    description
    Background of the Invention 1. Field of the Invention The present invention relates to a portable apparatus, in particular, a portable timepiece equipped with a push button. 2. Description of the Related Art Some portable devices such as a portable timepiece, a wristwatch or a pocket watch, a stopwatch, a cellular phone, and a personal digital assistant, mounted on the body of the apparatus, have a push-button for actuating, for example, a contact in FIG Device body on. In the case of, for example, a portable timepiece, it is possible to turn on the illumination of the dial by depressing the push button by a predetermined stroke, or to switch the display of the timepiece from analog to digital display, or vice versa, or to correct the date or day of the week is displayed digitally.
    In a portable device of this type, the push button is urged by a spring in a direction opposite to its Eindrückrichtung, which is why the release of the push button is prevented by a tube by this spring force. For this purpose, a type C or type E retaining ring designed to be stopped by one end of the pipe is provided at an end portion of the push button which extends through the pipe fixed to the apparatus body into the interior of the apparatus body.
    In view of this design, the conventional portable device is provided with a locking member to prevent wrong operation of the push button. The locking element has an internal thread formed in its inner circumference, which is in threaded engagement with a male thread formed on the outer circumference of the tube attached to the device body, and which is adapted to change between a threaded position between a locking position and an unlocked position by a change in engagement is movable (see, for example, JP-A-2003-7164 (Patent Literature 1)).
    In this design, the locking element, when the locking member is moved to the unlocked position, released from the head of the push button, which has moved through the pipe. Accordingly, the operation for pushing the push button is possible with a stroke corresponding to the release distance. Conversely, when the lock member is moved to the lock position, the lock member is brought into contact with the head of the push button. As a result, pressing the push button is prevented.
    In the prior art technique, the snap ring mounted on the push button is stopped by one end of the tube within the body of the device, whereby the push button is fixed in position; and the locking member moved to the locking position is brought into contact with the head of the push button in this state. Therefore, even in the state in which the push button is locked, the state of engagement with each other between the external thread and the internal thread is maintained.
    Essentially to achieve the locking position by the locking element, it may happen that the locking element with the internal thread or a rotating ring by the user is mistakenly rotated too far.
    Such a wrong operation is possible for the following reasons. That is, the strength of the locking ring is not so large, and it can be relatively easy to elastic deformation of the locking ring; Further, the retaining ring has a gap, so that it can deform such that its diameter is reduced. Consequently, because of the elastic deformation of the locking ring, it is rather difficult for the user to perceive that the locking element has reached the locking position. As a result, it may happen that the locking member or the rotary ring is incorrectly operated as described above.
    As a result, if the locking element or the rotary ring is erroneously turned too far, it may happen that the deformed locking ring is pulled into the tube. Therefore, there is a fear that a smooth axial movement of the push button after the wrong operation is prevented. In particular, when the locking member or the rotary ring is designed with a larger diameter to improve the operability, the torque due to the above-mentioned wrong operation is increased. As a result, the snap ring can be deformed more easily and there is a high probability that the snap ring will be pulled into the tube. Further, the problem due to the above-mentioned wrong operation is a hindering factor in the design of the locking member or the rotary ring having a larger outer diameter.
    One can possibly overcome the above-mentioned problem by increasing the wall thickness of the circlip or forming the circlip from a high-strength material to make it difficult for the circlip to undergo deformation. However, this makes it necessary to re-develop a specially provided locking ring, which leads to an increase in costs. Moreover, the process of attaching / detaching the circlip to / from the shaft of the pushbutton is a problem since it causes a considerable deterioration in the
    Feasibility results when the components are removed to clean the pushbutton. Therefore, the above measure is not desirable.
    And it is desirable to prevent an increase in the cost of avoiding the generation of a problem due to the above-mentioned erroneous operation. For this purpose, it is desirable to avoid increasing the number of components as much as possible and to make the component structure as simple as possible. When these conditions are met, assembly and component manufacturing are easier and cost increases can be prevented.
    Summary of the Invention It is an object of the present invention to provide a portable device, particularly a portable timepiece, which has a simple construction and yet helps to prevent the locking element from being in the locked position when in the state of being in the locking position has been moved, in which the pressing of the push button is prevented, is erroneously operated excessively.
    In order to achieve the above object, according to the present invention, there is provided a portable apparatus comprising: a device body having a through hole; a single-piece pipe inserted into the through-hole with an insertable pipe section and fixed to the apparatus body, and an outer pipe section formed integrally with the insertable pipe section projecting from the apparatus body and having a stopper; outer pipe section an external thread is formed; a locking member having an internal thread, a locking part and a locking portion, formed and configured such that it is movable by means of a threaded engagement of the internal thread with the external thread of the tube in the axial direction of the tube, whereby the locking portion is movable relative to the stop and upon contact of the Locking portion with the stop the movement of the locking element is limited; a push button comprising a shaft which is axially movably received in the tube, and whose one end is formed as a head which projects from the device body and which has a stop surface for the locking part; a spring, which pushes the push button to the outside of the body of the device; and a locking ring disposed at the other end of the shaft, which is disposed within the body of the device and which prevents the push button from disengaging from the tube.
    The portable device according to the present invention may be applied to a portable timepiece such as a wrist watch or a pocket watch, a stop watch, a mobile phone, a personal digital assistant, etc., and the apparatus body thereof is an outer case or the like. In the present invention, it is desirable to use an end face on the back of the head for the abutment surface of the head of the push button; but the stop surface can also be something other than a surface. In the present invention, a type C or type E circlip may be used as the circlip.
    When it is said in the context of the present invention that the spring urges the push button towards the outside of the device body, this means that the spring pushes the push button upwards, if the push button is provided so that they from the front of the Device body is pressed forth; and if the pushbutton is pressed in from a side surface of the apparatus body, it means that the spring urges the pushbutton laterally outwards.
    The locking element of the portable device of the present invention is rotated by a user such as a user. By this operation, the engagement between each other between the external thread of the pipe attached to the device body and the internal thread of the locking element undergoes a change, and by this change, the locking element moves between an unlocked position and a locking position. The arranged in the unlocking locking element allows the process of pressing the push button. The locking element arranged in the locking position restricts the movement of the pushbutton so that the pushing-in process can not be carried out on the pushbutton.
    In the state in which the locking element has been moved by a rotary actuator into the locking position, so the locking portion of the locking element is spaced from the stop formed on the pipe. In the same state at the same time the locking part of the locking element is spaced from the abutment surface of the head of the push button. Consequently, it is possible to depress the pushbutton. When the push button is depressed, it is possible to actuate by its shaft a key reaction element such as a contact arranged in the device body.
    In the state in which the locking member has been moved by a rotary operation in the locking position, the locking part of the locking element is in close proximity or in contact with the abutment surface of the head of the push button. Consequently, the locking member acts as a stop and the push button is retained so as not to be pressed.
    At the same time, the locking portion of the locking member in the state in which the locking member has been moved to the locking position, in contact with the stopper of the tube. Since the insertable Rohrrab section of the tube is attached to the device body, the locking element is held in the state in which it is fixed on the device body in the position, so that the locking element due to the contact (engagement) between the locking portion and the stop no further can move away from the device body.
    As a result, even if the user or the like tries to further rotate the locking member moved to the locking position, it can be prevented that the locking member is excessively rotated in the wrong direction. That is, the erroneous operation of the lock member moved to the lock position is prevented and, as a result, excessive stress is prevented from being applied to the lock ring.
    In this case, even if the locking element due to the engagement into each other on the threaded engagement portion between the internal thread and the external thread can rotate slightly, the force which tends to rotate the locking element at this moment, via the pipe from the device body added. As a result, it can be prevented that the abutment surface of the push button is pressed strongly, so that it is released from the body of the device.
    Further, the tube having a stopper retaining the locking member in the locking position is not formed by combining a plurality of members; it is a single component. Therefore, there is no time, no effort and no construction to attach the stop made separately from the pipe to the pipe. As a result, the required number of components and assembly man-hours are small and the design is simple, which helps to achieve a cost reduction.
    Accordingly, in the portable apparatus of the present invention, with a simple structure, it can be prevented that an excessive load is exerted on the locking ring via the push button, and thereby the fear that the locking ring is deformed and into the pipe can be precluded is pulled.
    In a preferred mode of the present invention, a portable device is provided in which the outer pipe section is formed with a pipe section of large diameter, on which the stop and the external thread are formed, and with a between the insertable pipe section and the Large diameter pipe section of small diameter pipe section having a smaller diameter than the pipe section of large diameter; wherein the stop is formed by a stepped transition between the large-diameter pipe section and the small-diameter pipe section; and the locking portion is formed by an annular end face of the locking member having a through hole having a larger diameter than the small diameter pipe portion and a smaller diameter than the large diameter pipe portion.
    In this preferred type, the locking portion formed by the annular end surface of the locking element in the state in which the locking element has been moved to the locking position, stopped by the stop, which is formed by the stage, the large portion of the pipe section Diameter and the pipe section is formed with a small diameter. As a result, this locking element is held on the device body in its position, so that it is not detached from the device body. Therefore, even if the locking member disposed in the locking position is rotated in the wrong direction, it can be prevented that the abutment surface of the push button is strongly pressed by the locking part of the locking member, so that it is released from the device body. Consequently, with a simple design, the fear can be ruled out that the circlip is deformed and pulled into the pipe.
    In a preferred mode of the present invention, a portable device is provided in which the outer tube section is formed with a pipe section of large diameter, on which the stop and the external thread are formed, and with a between the insertable pipe section and the Large diameter pipe section of small diameter pipe section having a smaller diameter than the pipe section of large diameter; the male thread being formed on the large diameter pipe section such that one end of the male thread merges into the stopper formed by a stepped transition between the large diameter pipe section and the small diameter pipe section; the abutment is formed by an incomplete threaded portion of the external thread, which is spaced from the stepped transition; and the locking portion is formed by one end of the internal thread formed integrally with the locking part.
    In this preferred type, the locking portion formed by one end of the internal thread of the locking member in the state in which the locking member has been moved to the locking position, held in contact with the stop, which of the incomplete threaded portion of the external thread of the pipe section large diameter of the tube is formed. As a result, the locking element is held on the device body in its position, so that it is not detached from the device body. Therefore, even if the locking member arranged in the locking position is rotated in the wrong direction, it can be prevented that the abutment surface of the push button is strongly pressed by the locking part of the locking member, so that it is detached from the device body. Consequently, with a simple design, the fear can be ruled out that the circlip is deformed and pulled into the pipe.
    In a preferred mode of the present invention, a portable apparatus is provided in which the small diameter pipe section has a larger diameter than the insertable pipe section; and the step formed by the small-diameter pipe section and the insertable pipe section is held in contact with a bottom surface of a recess formed in the apparatus body so as to be open to the outside of the apparatus body.
    In this preferred mode, the stage of the pipe attached to the apparatus body and the bottom surface of the recess of the apparatus body are held in contact with each other, whereby the introduced into the through hole of the device body tube fixed in the axial direction with respect to the device body in position can be. As a result, the large-diameter stopper and the pipe portion are located at a suitable position with respect to the bottom surface of the recess, so that it is easy to control the stroke of the locking member between the locking position and the unlocking position.
    In a preferred mode of the present invention, there is provided a portable apparatus in which the locking member has a small-diameter pipe section with the inner thread formed in its inner circumference, a large-diameter pipe section having a larger diameter than that of the small-diameter pipe section and covering the outer periphery of the head, and having the bottom wall integrally connecting the large-diameter pipe section and the small-diameter pipe section to form the recess together with the large-diameter pipe section; and between the pipe section with a large diameter and the head a sealing ring is provided.
    In this preferred mode, when the user rotates the lock member and pushes the push button, the user can have an appropriate operation feeling thanks to the sliding resistance of the seal ring. At the same time the penetration of foreign bodies such as grains of sand can be prevented by a gap between the pipe section with a large diameter of the locking element and the outer circumference of the head by means of the sealing ring.
    In order to achieve the above object, according to the present invention, there is provided a portable apparatus according to any one of the above aspects of the invention, which is a portable timepiece.
    According to the present invention, a portable timepiece is formed by a portable apparatus according to any one of the above aspects of the invention, so that a portable timepiece can be provided in which, with a simple construction, it can be prevented that the locking member in the Condition in which the locking member has been moved to the locking position in which the pressing of the push button is prevented, is erroneously turned too far.

    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment of the present invention will be described with reference to Figs.
    In Figs. 1 to 5, reference numeral 11 denotes a portable apparatus such as a portable timepiece, and more specifically, a wristwatch used as a waterproof timepiece. The wristwatch 11 is provided with a device body, e.g. a timepiece outer body 12, provided.
    As shown in Figs. 4 and 5, the timepiece outer body 12 accommodates the required elements including a display dial such as a dial 13, a display control device, e.g. a movement 15 configured to control the movement of a clock 14 for indicating the time of day, comprising a lamp (not shown) and a battery (not shown) as the power source.
    The movement 15 has at least one, for example, two key reaction elements (Figs. 4 and 5 each show one of them) such as contacts 16. These contacts 16 are formed of leaf springs or the like and are from the outer periphery of the movement 15 from. The contacts 16 are depressed by push buttons 61 described below, with the movement 15, etc., each having one of the push buttons 61 assigned function. For example, the lower right push button 61 in FIG. 1 has a function for starting and stopping the time measurement, and the upper right push button 61 in FIG. 1 has a function for turning on and off a lamp.
    As shown in FIGS. 4 and 5, the timepiece outer body 12 has a body 21 formed with an annular shape of a metal such as stainless steel or titanium, and a cover glass 22 which makes a dial 13 visible. is attached in a liquid-tight manner to the end face of the body 21; at the same time, a watch bottom 23 made of metal, synthetic resin or the like is attached to the back surface of the body 21 in a liquid-tight manner.
    In Figs. 4 and 5, reference numerals 25 and 26 denote seals for maintaining the liquid-tightness of the timepiece outer body 12. In Figs. 1 to 3, reference numeral 28 denotes a crown.
    Next, the construction for arranging push-button devices 33 described below at predetermined locations on the timepiece outer body 12, e.g. in two places of the body 21 forming the side wall of this timepiece outer body 12. The two push button devices 33 and the constructions for arranging them on the timepiece outer body 12 are the same, and therefore, the construction for arranging the push button device 33, which is for turning on and off the lamp for illuminating the dial 13, on the body 21 with reference to FIGS. 4 and 5 will be described.
    The body 21 has a recess 31 and a through hole 32. As shown in Fig. 5, the recess 31 opens to the outer surface of the body 21 a (outer side surface of the outer body) of the body 21. One end of the through-hole 32 is open to a bottom surface 31 a of the recess 31, and the other end of the through-hole 32 is toward the inner surface of the timepiece outer body 12, e.g. the body inner surface 21b (inner side surface of the outer body), open toward. The recess 31 and the through-hole 32, which has a smaller diameter than this, are both circular and they are provided coaxially.
    Next, the push-button device 33 will be described with reference to FIGS. 4 to 6. The push-button device 33 is provided with a pipe 35, a lock member 51, a push button 61, a lock ring 64, and a spring 71.
    The tube 35 consists of a single part, which is formed of a metal such as stainless steel or titanium; it has a cylindrical shape and is provided with an insertable pipe section 36 and an outer pipe section 37 formed therewith continuously. The material of the tube 35 is not limited to metal; It can also be made of synthetic resin.
    The insertable tube section 36 is a straight tube, e.g. is pressed into the through hole 32; its distal end portion may be reduced in diameter.
    The outer tube section 37 has a large-diameter tube section 37a and a small-diameter tube section 37b. The insertable pipe section 36 passes over the small-diameter pipe section 37b into the large-diameter pipe section 37a. The small-diameter pipe portion 37b has a smaller diameter than the large-diameter pipe portion 37a. As a result, the small-diameter pipe portion 37b merges with a step into the large-diameter pipe portion 37a. It is desirable that the small-diameter pipe portion 37b has a diameter larger than the outer diameter of the insertable pipe portion 36. As a result, the insertable pipe section 36 and the small-diameter pipe section 37b merge into one another via a step.
    The outer tube section 37 has an external thread 38 and a stop 39 integrally formed therewith. More specifically, the male thread 38 is formed on the large-diameter pipe portion 37a and over, for example, the entire outer periphery of this portion. This external thread 38 is provided so as to cause a locking member 51 described below to move back and forth in the axial direction. The stopper 39 is formed by a step between the large-diameter pipe section 37a and a small-diameter pipe section 37b. This stop 39 merges into one end of the external thread 38.
    The spring receiving groove 40 opens to the end face of the pipe section with a large diameter 37a out, that is to the end face on the side opposite to the step that forms the stop 39.
    The tube 35 is inserted into the body 21 and fixed to it. That is, the insertable pipe portion 36 of the pipe 35 is pressed in from the outside of the body 21 to thereby be inserted into the through hole 32. In this case, the insertable pipe section 36 is inserted until the step formed by the small-diameter pipe section 37b and the insertable pipe section 36 comes into contact with the bottom surface 31a of the recess 31. The insertion of the tube 35 into the through-hole 32 is performed in a state where the locking member 51 has previously been threadedly engaged with the outer tube portion 37.
    The tube 35 is attached to the body 21. For this attachment, a solder material 34 is used, which consists for example of metal. The solder material 34 is received by an annular groove formed at a corner portion formed by the bottom surface 31 a of the recess 31 and the through hole 32. The solder material 34 is covered by the outside of the body at the stage of the tube 35.
    The distal end portion of the insertable pipe section 36 fixed as described above protrudes into the interior of the body 21. Thus, the outer tube portion 37 of the tube 35 fixed to the timepiece outer body 12 is outside the body 21, i. outside the timepiece outer body 12, arranged.
    The locking member 51 covering the outer tube portion 37 is mounted thereon so as to be movable in the axial direction of the tube 35.
    More specifically, the locking member 51 is formed by a metal ring having a stepped shape. The locking member 51 is provided with a small-diameter pipe section 52, a large-diameter pipe section 53, a lock member 54, an internal thread 55, and a lock portion 56.
    The outer diameter of the small-diameter pipe section 52 is smaller than the diameter of the recess 31. The inner thread 55 is formed on the inner surface of this small-diameter pipe section 52. The inner diameter and the outer diameter of the large-diameter pipe portion 53 are larger than the diameter of the recess 31 and the diameter of the outer pipe portion 37. A plurality of grooves 53a (see FIG. 6) for preventing the fingers from slipping off upon manual operation of the locking member 51 are formed in the outer periphery of the large-diameter pipe portion 53 so as to be parallel to the axial direction of the locking member 51.
    The locking member 54 is a wall extending in a direction perpendicular to the axial direction of the locking member 51 direction; this locking part 54 extends between the small-diameter pipe section 52 and the large-diameter pipe section 53 to integrally connect them. A key depression recess 51a is defined by the large-diameter pipe portion 53 and the lock member 54, and the lock member 54 includes the bottom of this key press-in recess 51a. The inner diameter of the key press-in recess 51a is larger than the diameter of the inner thread 55, and is slightly larger than the outer diameter of a head 63 described below.
    The lock portion 56 is formed by an end face of the lock member 51. That is, the locking portion 56 is provided integrally and continuously at the end on the side of the small-diameter pipe portion 52 opposite to the locking portion 54 so as to narrow the opening of this end. The diameter of a through hole 56a formed in the center of this locking portion 56 is larger than the diameter of the small diameter pipe portion 37b and smaller than that of the large diameter pipe portion 37a.
    The internal thread 55 of the locking element 51 is in threaded engagement with the external thread 38 of the outer tube section 37, and the locking element 51 is mounted on the outer tube section 37 so that it is movable in the axial direction of the tube 35, wherein the outer Tube section 37 covered. In the state in which the locking member 51 is supported by the pipe 35, the locking portion 56 of this locking member 51 between the bottom surface 31 a of the recess 31 and the stopper 39 is arranged.
    The pushbutton 61 is carried by the tube 35. The pushbutton 61 consists of a one-piece molded part made of metal or synthetic resin and has a shaft 62 and a head 63.
    The shaft 62 has a columnar shape and is longer than the axial length of the tube 35. This shaft 62 extends in the axial direction through the tube 35 and a locking ring 64, which prevents the release of the push button 61 of the tube 35 is mounted on the shaft end (distal end) of the shaft 62, which projects into the interior of the body 21. The locking ring 64 is formed of metal and is of type C or type E; its size is large enough to cause it to be stopped by the end face of the insertable tube section 36, which projects into the interior of the body 21.
    The shaft 62 has a continuous annular Dichtungsaufnahmenut in its circumferential direction. A gasket 66 is fittingly engaged with this gasket receiving groove and mounted on the shaft 62. The seal 66 is formed with a ring-like shape of a rubber or plastic-like material that can deform elastically. In the elastically deformed state, the seal 66 is held in close contact with the inner circumferential surface of the tube 35. By this seal 66, the seal between the tube 35 and the shaft 62 is accomplished, whereby the interior of the body 21 is made waterproof and dustproof.
    The head 63 is integrally provided on the other shaft end of the shaft 62. The outer diameter of the head 63 is slightly smaller than the diameter of the key press-in recess 51a. This head 63 has a stop surface 65. The abutment surface 65 is formed, for example, by the annular end face on the back of the head 63.
    The shaft 62 of the push button 61 is inserted from the outside of the body 21 in the tube 35 and guided by it; then the snap ring 64 is mounted on the shaft end portion of the shaft 62, which projects into the interior of the body 21, whereby the push button 61 is mounted so that it is prevented from detaching from the tube 35. By this mounting, the head 63 is fitted into the outside of the timepiece outer body 12 and into the inside of the push-button recess 51a to be arranged therein. At the same time causes the abutment surface 65 opposite the locking part 54 of the locking member 51.
    A spring such as a coil spring 71 is held between the outer tube portion 37 and the head 63 in a compressed state. The part of the coil spring 71 on the side of the outer tube portion 37 is housed in a spring receiving groove 40. This coil spring 71 can be further compressed by pressing the push button 61.
    By the spring force of this coil spring 71, the pushbutton 61 is urged in the direction of the outside of the timepiece outer body 12 (more precisely in the direction of the outside of the body 21). Thereby, the snap ring 64 is held in the state of being stopped by the end face of the tube 35 protruding into the interior of the timepiece outer body 12.
    Next, the methods by which the push-button device 33 is assembled will be described. First, the internal thread 55 of the locking member 51 is brought from the side of the insertable pipe section 36 of the tube 35 into threaded engagement with the external thread 38 of the large-diameter tubular section 37a of the tube 35 so as to mount the locking element 51 on the tube 35, the locking element 51 covers the outer tube section 37. Thereafter, the soldering material 34 is accommodated in the annular groove formed at the corner portion formed by the bottom surface 31 a of the recess 31 of the body 21 and the through-hole 32.
    In this state, the insertable pipe portion 36 of the pipe 35 is inserted into the through hole 32 from the outside of the body 21 until the step portion formed by the insertable pipe portion 36 of the pipe 35 and the small diameter pipe portion 37b is inserted. comes into contact with the bottom surface 31 a of the recess 31. Subsequently, the brazing material 34 is melted by heating, and then this brazing material 34 solidifies, thereby fixing the tube 35 to the body 21.
    Next, the gasket 66 is mounted to the shaft 62 of the push button 61, and the coil spring 71 is fitted into engagement with the shaft 62 so as to be wound around it.
    Finally, the pushbutton 61 is mounted on the tube 35 in this state. That is, the shaft 62 of the push button 61 is inserted from the outside of the body 21 into the tube 35 and guided therethrough. At the same time, the gasket 66 is compressed and brought into close contact with the inner peripheral surface of the tube 35, and the coil spring 71 is compressed while being accommodated in the spring receiving groove 40 of the outer tube portion 37. In this state, in which the shaft 62 is thus passed through the tube 35, the locking ring 64 is mounted on the distal end portion of the shaft 62, which projects into the interior of the body 21, thereby preventing the release of the push button 61.
    To release the push button 61 when the wristwatch 11 is disassembled for cleaning, the snap ring 64 is released, whereby it is possible to pull the push button 61 out of the tube 35 to the outside of the body 21. Thus, it is possible to clean the external thread 38 and to replace the seal 66 and the coil spring 71.
    The pushbutton 61 of the wristwatch 11 described above is in a state of being urged by the coil spring 71 in a direction opposite to the push-in direction of this key. In this case, the snap ring 64 is stopped by the distal end portion of the insertable pipe section 36, thereby preventing the push button 61 from being released.
    The locking member 51 of this wristwatch 11 is turned by the user when it allows or inhibits the depression of the push-button 61.
    When the depression of the push button 61 is permitted, the lock member 51 is rotated to be located in the unlocking position shown in Figs. 2 and 4.
    That is, the locking member 51 is rotated to shorten the length of engagement of the external thread 38 and the internal thread 55 into each other, whereby the locking member 51 is moved to the position (unlocked position) in which the locking portion 56 at one of his End in contact with the bottom surface 31 a of the recess 31 of the body 21 is.
    The locking member 51 moved to the unlocking position is in a state of being fixed in position on the body 21 of the timepiece outer body 12. In this state, the locking portion 56 of the locking member 51 is farthest from the stopper 39 of the tube 35, and the locking part 54 of the locking member 51 is farthest from the abutment surface 65 of the head 63 of the push button 61. Consequently, it is possible to depress the push button 61 according to the distance between the lock member 54 and the abutment surface 65.
    When the push button 61 is pushed against the spring force of the coil spring 71 from the outside of the body 21 in the state where the lock member 51 has been moved to the unlocked position, the distal end portion 62a of the shaft 62 depresses the contact 16 which is located near at and opposite to him. As a result, the movement 15 is operated to perform the function assigned to the push button 61 and to turn on the lamp for illuminating the dial, for example. Thereafter, when the depression of the push button 61 is released, the push button 61 is returned to the previous state by the spring force of the coil spring 71, so that the lamp is turned off.
    When the accidental depression of the push button 61 during transportation, etc. of the wristwatch 11 is inhibited, the locking member 51 is rotated and arranged in the locking position shown in Figs.
    That is, the locking member 51 is rotated so that the length of engagement of the external thread 38 and the internal thread 55 is extended into each other, whereby the locking member 51 is moved to a position (locking position) in which its locking portion 56 of the Bottom surface 31 a of the recess 31 of the body 21 is spaced and is stopped by the stop 39 of the tube 35. In this case, the locking member 51 is moved in the axial direction so as to protrude laterally from the body 21. This movement of the locking member 51 is restricted by its locking portion 56 coming into contact with the stopper 39 of the tube 35, and it is not possible to further turn the locking member 51.
    In the state where the lock member 51 is located in the lock position, most of the head 63 of the push button 61 is buried in the key press-in recess 51a of the lock member 51, so that the user can know that the Pushbutton 61 is in a state in which it can not be pressed.
    When the push button 61 receives a depression force in the state where the lock member 51 has been moved to the lock position, the abutment surface 65 of the head 63 and the lock member 54 of the lock member 51 are in contact with or in close proximity to each other. Therefore, the locking member 54 functions as a stop and prevents the push button 61 is depressed.
    The tube 35 is thus fixed to the body 21 of the timing device outer body 12 by brazing. Therefore, in the state where the lock member 51 has been moved to the lock position, the load exerted on the lock member 54 from the body 21 via the pipe 35 can be endured (the pushing-in force of the push button 61). Consequently, it can be prevented that the push button 61 is depressed.
    As described above, in the state where the lock member 51 is located in the lock position, its lock portion 56 is in contact with the stopper 39 of the pipe 35. As a result, the lock member 51 can be prevented from being excessively rotated, so that the length of engagement of the external thread 38 and the internal thread 55 is extended into each other. Therefore, in spite of the fact that the lock member 51 and the head 63 are in contact with each other, there is no fear that the push button 61 is moved toward the outside of the body 21.
    Consequently, there is no fear that the circlip 64 mounted on the shaft 62 is pulled into the tube 35 under deformation. At the same time, there is no fear that the pushbutton 61 will be unintentionally released. Therefore, it is possible to improve the reliability of the push-button device 33 of a waterproof watch such as a diver's watch.
    In the above push-button device 33, the tube 35 with the stopper 39, which retains the locking element 51 in the locking position, not a combination of several elements, but a single component. Therefore, it does not take the time and effort and no construction to attach the stop made to the pipe 35 separately from the pipe 35. As a result, the required number of components and assembly man-hours for the push button device 33 is small and the design is simplified; and thus, the cost of the wristwatch 11 equipped with the push-button device 33 can be reduced.
    As described above, in the wristwatch 11 of the first embodiment, with a simple structure, it can be prevented that too much stress is applied to the snap ring 64 via the push button 61; and at the same time the fear can be ruled out that the retaining ring 64 is deformed and pulled into the tube 35.
    Further, in the push-button device 33, the small-diameter pipe section 37b of the outer pipe section 37 has a larger diameter than the insertable pipe section 36 of the pipe 35, and the step formed by the small-diameter pipe section 37b and the insertable pipe section 36 is Contact with the bottom surface 31 a of the recess 31 formed in the body 21 of the timepiece outer body 12 so as to be open to the outside of this body 21.
    Due to this configuration, the tube 35 inserted into and attached to the through-hole 32 of the body 21 can be fixed in position in the axial direction with respect to the timepiece outer body 12. As a result, the stopper 39 of the pipe 35 and the large-diameter pipe portion 37a are arranged with the male thread 38 at suitable positions with respect to the bottom surface 31a of the recess 31. Therefore, it is easy to control the stroke of the lock member 51 between the lock position and the unlock position.
    Figs. 7 to 9 illustrate the second embodiment of the present invention. Other than the description below, the structure of the second embodiment is the same as that of the first embodiment, and therefore the components having the same structure and function as those of the first embodiment will be denoted by the same reference numerals, and a description thereof will be omitted.
    In the second embodiment, the length of the external thread 38 formed in the outer circumference of the large-diameter pipe section 37a of the outer pipe section 37 of the pipe 35 is shorter than the axial length of the large-diameter pipe section 37a. Therefore, the external thread 38 has an incomplete threaded portion. This incomplete threaded portion is used as the stopper 39 and is provided at a position spaced from the step formed by the large-diameter pipe portion 37a and the small-diameter pipe portion 37b.
    Further, in the second embodiment, the small-diameter pipe portion 52 of the lock member 51 is a straight pipe, and the end of this small-diameter pipe portion 52 is open on the opposite side of the large-diameter pipe portion 53, and its opening is not narrowed , Consequently, the female thread 55 is formed over the entire small-diameter pipe portion 52 in its axial direction. In the second embodiment, the locking portion 56 of the locking member 51 is formed by the end of the internal thread 55 formed integrally with the locking member 54. Otherwise, this embodiment is similar to the first embodiment.
    In the second embodiment, when the pushing-in of the push-button 61 is permitted, the locking member 51 is rotated and arranged in the unlocking position shown in FIG.
    That is, the locking member 51 is rotated so that the length of engagement of the external thread 38 and the internal thread 55 is shortened into each other, whereby the locking member 51 is moved to a position (unlocked position), in which the distal end of the pipe section with small diameter 52 is held in contact with the bottom surface 31 a of the recess 31 of the body 21.
    The locking member 51 moved to the unlocking position is fixed on the body 21 of the timepiece outer body 12 in position. In this state, the locking portion 56 of the locking member 51 is furthest from the incomplete threaded portion stop 39, and the locking part 54 of the locking member 51 is farthest from the abutment surface 65 of the head 63 of the pushbutton 61. As a result, the push button 61 can be depressed by a distance corresponding to the distance between the lock member 54 and the stopper surface 65.
    When the push button 61 is pushed against the spring force of the coil spring 71 from the outside of the body 21 in the state where the lock member 51 has been moved to the unlocked position, the distal end portion 62a of the shaft 62 depresses the contact 16 which is very close to and opposite to him. As a result, the movement 15 is operated to perform the function assigned to the push button 61 and to turn on the lamp for illuminating the dial, for example. Thereafter, when the depression of the push button 61 is released, the push button 61 is returned to the previous state by the spring force of the coil spring 71, so that the lamp is turned off.
    When the accidental depression of the push button 61 during transportation, etc. of the wristwatch 11 is inhibited, the lock member 51 is rotated and arranged in the locking position shown in FIG.
    That is, the locking member 51 is rotated so that the length of engagement of the external thread 38 and the internal thread 55 is extended into each other, whereby the tube portion of small diameter 52 of the locking member 51 is moved to a position (locking position) its locking portion 56 is spaced from the bottom surface 31a of the recess 31 of the body 21 and in which the end (locking portion 56) of the internal thread 55 of the locking member 51 is in contact with the stopper 39 consisting of the incomplete threaded portion of the external thread 38 , In this case, the locking member 51 is moved in the axial direction so as to protrude laterally from the body 21. This movement of the locking member 51 is restricted by its locking portion 56 coming into contact with the stopper 39 of the tube 35, and it is not possible to further turn the locking member 51.
    When the push button 61 receives a depression force in the state in which the lock member 51 has been moved to the lock position, the abutment surface 65 of the head 63 and the lock member 54 of the lock member 51 are in contact with or in close proximity to each other , Therefore, the locking member 54 functions as a stop and prevents the push button 61 is depressed.
    The tube 35 is thus attached to the body 21 of the timepiece outer body 12 by brazing. Therefore, in the state where the lock member 51 has been moved to the lock position, the load exerted on the lock member 54 from the body 21 via the pipe 35 can be endured (the pushing-in force of the push button 61). Consequently, it can be prevented that the push button 61 is depressed.
    As described above, in the state where the lock member 51 is located in the lock position, its lock portion 56 is in contact with the stopper 39 of the pipe 35. As a result, the lock member 51 can be prevented from being excessively rotated, so that the length of engagement of the external thread 38 and the internal thread 55 is extended into each other. Therefore, in spite of the fact that the lock member 51 and the head 63 are in contact with each other, there is no fear that the push button 61 is moved toward the outside of the body 21.
    Consequently, there is no fear that the circlip 64 mounted on the shaft 62 is pulled into the tube 35 under deformation. At the same time, there is no fear that the pushbutton 61 will be unintentionally released. Therefore, it is possible to improve the reliability of the push-button device 33 of a waterproof watch such as a diver's watch.
    In the above push-button device 33, the tube 35 with the stopper 39, which retains the locking member 51 in the locking position, not a combination of several elements, but a single component. Therefore, it does not take the time and effort and no construction to attach the stop made to the pipe 35 separately from the pipe 35. As a result, the required number of components and assembly man-hours for the push button device 33 is small and the design is simplified; and thus, the cost of the wristwatch 11 equipped with the push-button device 33 can be reduced.
    As described above, in the wristwatch 11 of the first embodiment, with a simple structure, it can be prevented that too much stress is applied to the snap ring 64 via the push button 61; and at the same time the fear can be ruled out that the retaining ring 64 is deformed and pulled into the tube 35.
    Further, the configuration of the locking member 51 used in the second embodiment is simpler than the configuration of the locking member 51 used in the first embodiment; In addition, it is easy to machine the internal thread 55 with respect to the small-diameter pipe section 52. As a result, the cost of the locking member 51 can be reduced.
    Fig. 10 shows the third embodiment of the present invention. Other than the description below, the third embodiment has the same configuration as the first embodiment, and therefore the components having the same configuration and the same function as those of the first embodiment will be denoted by the same reference numerals, and a description thereof will be omitted ,
    In the third embodiment, the diameter (outer diameter) of the small-diameter pipe portion 37b of the outer pipe portion 37 is equal to the outer diameter of the insertable pipe portion 36.
    Further, in the third embodiment, a seal ring 75 is provided between the large-diameter pipe portion 53 of the lock member 51 and the head 63 of the push-button 61. Therefore, for example, at the distal end portion of the annular wall portion of the head 63, an annular groove is provided which is open to the outer periphery thereof. The sealing ring 75 is fittingly engaged with this annular groove, whereby the sealing ring 75 is mounted on the outer periphery of the head 63. The sealing ring 75 is formed of a rubber or plastic-like material that can deform elastically. The seal ring 75 is held in close contact with the inner peripheral surface of the large-diameter pipe section 53 of the lock member 51. This sealing ring 75 accomplishes the sealing between the pipe section with a large diameter 53 of the locking element 51 and the head 63 of the push button 61st
    Otherwise, this embodiment has the same construction as the first embodiment. Therefore, for the same reasons as mentioned with regard to the first embodiment, even in the third embodiment, with a simple construction, it is possible to prevent the locking ring 64 from being over-loaded by the push-button 61; At the same time, the fear can be ruled out that the circlip 64 will be deformed so that it will be drawn into the tube 35.
    Further, in the third embodiment, when the user rotates the lock member 51 and makes a pushing-in operation on the push-button 61, it is possible to give the user an adequate operation feeling thanks to the sliding resistance of the seal ring 75; Moreover, it is possible to prevent inadvertent rotation in the releasing direction of the locking member 51 disposed in the locking position, so that the locking member 51 is held in the locking position with high reliability. At the same time, this embodiment is better than the first embodiment, since it is possible, thanks to the sealing ring 75, to prevent the penetration of foreign bodies such as grains of sand through the gap between the large-diameter pipe section 53 of the locking element 51 and the outer circumference of the head 63.
