    TECHNICAL FIELD The present disclosure relates to a manual device with two opposite retractable heads, in which one head is retracted when the other head is in the position of use, and vice versa.
    In particular, such a manual device can be a writing instrument, but not only
    TECHNOLOGICAL BACKGROUND There are known writing instruments with two opposite retractable heads in which one head is retracted when the other head is in the position of use, and vice versa. However, your withdrawal mechanisms are not always entirely satisfactory, particularly from the point of view of ease of use. There is therefore a need in this sense.
    PR E S ENTATION An embodiment relates to a manual device, in particular a writing instrument, comprising a body extending. According to an axial direction and having a first axial end and a second axial end opposite the first end axial in the axial direction, a single carriage housed in the body at 20 being movable in translation in the axial direction relative to the body, the single carriage carrying a first head and a second head opposite to the first head in the axial direction, or a first carriage and a second carriage housed in the body being movable in translation in the axial direction relative to the body, the first carriage and the second carriage respectively carrying a first head and a second head opposite in the axial direction to the first head, and a single locking device comprising a single cavity and at least one ball or equivalent, a ball or equivalent of the at least one ball or equivalent blocking the single carriage or the first carriage relative to the body 30 when, considered in the direction of gravity, the first axial end is below the second axial end, so that the first head is locked relative to the body by projecting axially from the first axial end while the second head is retracted into the body, and a ball or equivalent of the at least 35 ball or equivalent blocking the single carriage or the second carriage when, considered in the direction of gravity, the first axial end is above the second axial end, so that the second head is locked relative to the body by projecting axially from the second axial end while that the first head is retracted into the body.
    It is understood that the manual device comprises either a single carriage, or a first carriage and a second carriage. By “single carriage” is meant a single and same entity capable of moving in one block in the axial direction, this entity possibly comprising a single part or several parts axially coupled in translation. By “a first carriage and a second carriage” is meant two carriages independent of one another, in particular in the axial direction. Thereafter, and unless otherwise indicated by "the cart" means "the only cart" or "the first cart and the second cart".
    By "direction of gravity" means of course the direction of Newtonian gravitational acceleration created by the Earth or more generally by the body or the star on which the manual device is used.
    By "ball or equivalent" means any solid element of any shape, movable in the cavity, and able to move in the cavity under the effect of gravity relative to the walls delimiting the cavity. Thereafter, and unless otherwise indicated, by "ball" means "ball or equivalent". For example, the ball is metallic, but not necessarily.
    The manual device can comprise a single ball or several balls (i.e. a plurality of balls), for example two or more balls. Thus, by “a ball or equivalent of the at least one ball or equivalent” is meant “the ball or equivalent” if the locking device comprises a single ball or equivalent or else “a ball or equivalent among the plurality of balls or equivalents ”if the locking device comprises several balls or equivalent. Thereafter, and unless otherwise indicated, by "the ball" means "the at least one ball or equivalent".
    The single cavity is formed by a single hollow volume, within which the ball can move under the effect of gravity. In other words, the cavity houses the ball. The shape of the cavity is arbitrary, and can be simple or complex. For example, the cavity may comprise one or more chambers, of fixed or variable dimensions, these chambers being interconnected by passages within which the ball can flow to pass from one chamber to another. The body and the carriage form all or part of the walls of the cavity. Thus, the shape and / or dimensions (or volume) of the cavity are likely to change depending on the relative position of the carriage relative to the body.
    For example, the first head and / or the second head is formed by any tool tip of a manual device, for example a wrench tip, a screwdriver, a blade, a punch, a body of writing (felt tip, ball point or other, graphite lead, chalk or any means allowing to write on a substrate), a brush, an eraser, a friction body, a tip (active or passive) configured to cooperate with a screen touchscreen, for example a capacitive, resistive, inductive, infrared, optical, electrostatic screen, etc., a cosmetic applicator (brush, pencil, mascara brush, ball applicator, lipstick or any means of cosmetic application), etc. .
    In the variant comprising a single carriage, thanks to the ball which moves within the cavity, when the first axial end is below the second axial end with reference to the direction of gravity, the only ball or a ball among the plurality of ball cooperates with the single carriage to block it relative to the body in the axial direction so that the first head carried by the single carriage extends out (ie at least partly out) of the body from the first axial end. In this case the second head is retracted (i.e. fully retracted) into the body. In this variant, the second head being mounted on the single carriage, it is also locked in this position.
    Conversely, still thanks to the ball which moves within the cavity, when the first axial end is above the second axial end with reference to the direction of gravity, the single ball or a ball among the plurality of balls cooperate with the single carriage to block it relative to the body in the axial direction so that the second head carried by the single carriage extends out (ie at least partially out) of the body from the second axial end. In this case the first head is retracted (i.e. fully retracted) into the body. In this variant, the first head being mounted on the single carriage, it is also locked in this position.
    In the variant comprising a first carriage and a second carriage, thanks to the ball which moves within the cavity, when the first axial end is below the second axial end with reference to the direction of gravity , the single ball or a ball among the plurality of ball cooperates with the first carriage to block it relative to the body in the axial direction so that the first head carried by the first carriage extends out (ie at least in outside part) of the body from the first axial end. In this case the second head is retracted (i.e. fully retracted) into the body. The second carriage carrying the second head may or may not be locked relative to the body.
    Conversely, still thanks to the ball which moves within the cavity, when the first axial end is above the second axial end with reference to the direction of gravity, the single ball or a ball among the plurality of balls cooperate with the second carriage to block it relative to the body in the axial direction so that the second head carried by the second carriage extends out (ie at least partially out) of the body from the second end axial. In this case the first head is retracted (i.e. fully retracted) into the body. The first carriage carrying the first head may or may not be locked relative to the body.
    Thus, both in the first variant and in the second variant, it is understood that the manual device takes a first configuration in which the first head projects from the body from the first end while the second head is retracted into the 1st body and a second configuration in which the second head protrudes from the body from the second end while the first head is retracted into the body. In the first configuration the first head is in a position of use while the second head is in the retracted position, and conversely, in the second configuration the second head is in a position of use while the first head is in the retracted position .
    To go from the first configuration to the second configuration and vice versa, the first end is passed, which is below the second end in the first configuration, above the second end, and vice versa. change, thanks to gravity, the ball which cooperates with the single or the first carriage in the first configuration is released and circulates in the cavity to no longer cooperate with the single or the first carriage, and a ball, the same or another comes to cooperate with the single or the second carriage in the second configuration. In other words, the blocking device is a gravity blocking device which operates automatically and only through the effects of gravity.
    If there is a single ball, it is this single ball which cooperates with the single carriage or with the first and second carriages. If there are several balls, for example a first ball cooperates with the single carriage or the first carriage in the first configuration and a second ball, distinct from the first ball, cooperates with the single carriage or the second carriage in the second configuration.
    Thus, thanks to the locking device comprising the single cavity and the ball, the head that the user intends to use (ie the head which faces downward relative to the direction of gravity) automatically comes into the use position and is locked there while the other head comes automatically into the retracted position. This makes the use of the manual device particularly easy.
    In some embodiments, the single cavity comprises a first chamber and a second chamber separate from the first chamber, the first chamber being formed between the body and the single carriage or between the body and the first carriage, the second chamber being formed between the body and the single carriage or between the body and the second carriage, a ball or equivalent of the at least one ball or equivalent being housed in the first chamber when, considered according to the direction of gravity, the first axial end is below the second axial end, and a ball or equivalent of the at least one ball or equivalent being housed in the second chamber when, considered in the direction of gravity, the first axial end is above the second axial end.
    The single cavity comprises two chambers, namely the first chamber and the second chamber, the first chamber being configured to receive the ball which cooperates with the single or the first carriage in the first configuration while the second chamber is configured to receive the ball which cooperates with the single or the second carriage in the second configuration.
    This allows to perfectly configure the single ball cavity according to the configuration of the manual device. The precision of the locking device is improved, which contributes to the ease of use.
    In certain embodiments, the dimensions (or else the volume) of the first chamber and / or the dimensions (or else the volume) of the second chamber are variable depending on the relative position of the single carriage or first and second carriages relative to the body.
    For example, the dimensions of the first and / or the second chamber vary so that the space of the first and / or of the second chamber configured to receive a ball varies between a zero space and a predetermined maximum space not bad.
    This ensures a reduced size of the locking device, which gives the manual device dimensions suitable for easy gripping and handling.
    In some embodiments, each chamber includes an entrance and a bottom, all or part of the walls of the first chamber and / or all or part of the walls of the second chamber converge from the entrance to the bottom.
    We understand that the entrance to a room is the place through which passes the ball to enter / exit the room while the ball can not go beyond the bottom of the room when it is in bedroom. The bottom can be closed or open. For example, the ball may protrude partially from the chamber from the bottom, but cannot completely exit the chamber from the bottom. For example the walls of the chamber extending between the entrance and the bottom of the chamber, called side walls, are inclined relative to each other (ie are not parallel) so that the space between the side walls decrease from the entrance to the bottom. For example, the maximum space between the walls of the chamber at the bottom of the chamber is less than the diameter of the ball configured to be housed in said chamber.
    Convergent walls ensure that the ball configured to be received in the chamber cooperates with the walls 5 of the chamber so as to block the carriage axially without play relative to the body. In other words, the converging walls form a backlash system. Thus, when using the head carried by the carriage which is in the position of use, there is no, or very little, axial play, so as to ensure a certain comfort and a certain ease of use. .
    In some embodiments, the single cavity comprises a passage for the at least one ball or equivalent extending between the first chamber and the second chamber, the passage being formed between the body and the single carriage or between the body and the first 15 and second carriages.
    This passage allows the ball to flow between the first chamber and the second chamber. It is therefore understood that the first passage is arranged axially between the first chamber and the second chamber. For example, the single cavity includes only the first chamber, the second chamber and the passage connecting the first and second chambers. For example, the passage is delimited only by the body and the carriage.
    This ensures a reduced size of the locking device, which provides the manual device with dimensions 25 suitable for easy gripping and handling.
    In some embodiments, the manual device comprises at least one striker configured to strike a ball of the at least one ball or equivalent when, considered in the direction of gravity, the first axial end passes from a position 30 above the second axial end at a position below the second axial end, and / or when viewed in the direction of gravity, the first axial end passes from a position below the second axial end to a position above the second axial end.
    In other words, your striker is configured to strike the ball that blocks the carriage relative to the body. For example, the striker can be a movable counterweight axially distinct from the at least one ball or else a ball from the at least one ball. It is therefore understood that the striker is mobile under the effect of gravity. For example, the striker is configured to strike the ball in the axial direction.
    When moving from the first configuration to the second configuration or vice versa, the striker facilitates the release of the ball which blocks the carriage relative to the body. This ensures that the carriage is well unlocked and free to move axially within the body. Such a striker avoids any untimely blocking of the carriage within the body and ensures even easier use of the manual device.
    In some embodiments, the manual device comprises two strikers and, considered in the axial direction, the at least one ball or equivalent is disposed between the two strikers.
    It is therefore understood that a first striker allows to release the single ball when we want to go from the first configuration to the second configuration while the second striker allows to release the single ball when we want to go from the second configuration to the first configuration. Of course, this structure with a single ball and two strikers can be used both in manual devices comprising a single carriage and in manual devices comprising two carriages. Such a structure is particularly reliable.
    In some embodiments, the two strikers are coupled (i.e. are mechanically coupled) in the axial direction.
    By coupling the two strikers it increases the mass of the movable assembly striking the ball which blocks the carriage in position. The percussive unlocking effect is thus improved so that the handling of the manual device is further facilitated.
    BRIEF DESCRIPTION OF THE DRAWINGS The object of this presentation and its advantages will be better understood on reading the detailed description given below of various embodiments given by way of nonlimiting examples. This description refers to the pages of attached figures, on which:
    FIG. 1 represents a first embodiment of the manual device,
    FIG. 2 represents an axial section view of the manual device of FIG. 1,
    FIGS. 3A to 3E represent the different stages for the transition from the first configuration to the second configuration, and
    - Figure 4 shows a second embodiment of the manual device.
    DETAILED DESCRIPTION FIG. 1 represents a manual device 10, in this example a writing instrument, and more particularly a pen with retractable ball point, comprising a body 12 which extends in an axial direction X. The body 12 has a first axial end 12A and a second axial end 12B, opposite the first axial end 12A in the axial direction X. A first head 14A is configured to project, retractably, from the first axial end 12A while a second head 14B is configured to project, retractably, from the second axial end 12B. In this example the first head 14A is a ball point with thermochromic ink while the second head 14B is a friction body. As a reminder, a friction body is a body configured to be rubbed on a surface, for example to generate heat and cause a thermochromic ink to change color, that is to say an ink which changes color as a function of the heat to which it is subjected. Of course, any other head can be envisaged both for the first head and for the second head. In FIG. 1 the first head 14A projects from the body 12 from the first axial end 12A while the second head 14B is retracted into the body 12. In other words, the first head 14A is in the position of use while the second head 14B is in the retracted position. It is noted that the body 12 is equipped with a retractable protection 16 configured to protect the first head 14A and to avoid accidental staining when the manual device 10 is not used. This retractable protection 16 takes the form of a sheath movable axially between a protection position (in broken lines in FIG. 1)) in which it protects the first head 14A, even when it is in the use position, and a release position (in solid lines in FIG. 1), in which the first head 14A can be normally used when it is in the position of use. This protection 16 comprises means known moreover by a person skilled in the art for moving it between these two positions, in particular a button 16A, and for keeping it in the protection position and in the release position.
    The manual device 10 will now be described in more detail with reference to Figure 2. The manual device 10 has in this example a single carriage 14 housed in the body 12 and movable 10 axially within the body 12. This carriage 14 carries the first head 14A and the second head 14B, the first head 14A being disposed on the side of the first axial end 12A while the second head 14B is disposed on the side of the second axial end 12B. In this example, each head is mounted on the carriage 14 by screwing, but of course any other mounting method known moreover to those skilled in the art is conceivable.
    In this example, the single carriage 14 comprises two identical parts 14-1 and 14-2 distinct and mounted together, so as to be mechanically coupled. In particular, these two parts 1420 1 and 14-2 are coupled in translation in the axial direction X. Each part 14-1 and 14-2 has a base 15A extending in the axial direction X on which is fixed a head 14A or 14B, and a receptacle 15B configured to receive the ball 18B of the locking device 18 described later. In this example, the concavity of the receptacle 15B 25 has an inverted "V" shape, the ball 18B being able to go on one side or the other of the "V". Of course, according to a variant, the concavity of the receptacle can have any other shape, for example a single branch of the "V" or else a conical or frustoconical shape.
    In this example, the two parts 14-1 and 14-2 are assembled by clipping via axial tabs extending from the receptacles, so that the receptacle for each part is vis-à-vis according to the axial direction X with the receptacle of the other part. Of course these two parts 14-1 and 14-2 can be assembled together by any other means known moreover to those skilled in the art. According to a variant 35 shown in Figure 4, the parts 14-Γ and 14-2 'do not have assembly means and are independent of one another. Thus, the manual device of the variant of FIG. 4 has a first carriage 14-Γ and a second carriage 14-2 'separate from the first carriage 14-1'.
    The manual device 10 comprises a single locking device 18 having a single cavity 18A and in this example a single metal ball 18B housed in the single cavity 18A. According to a variant, there could be two or more balls circulating in the single cavity 18A.
    The cavity 18A is formed between the carriage 14 and the body 12 and has a first chamber 18A1, a second chamber 18A2 separate from the first chamber 18A1, and a passage 18A3 connecting the first and second chambers 18A1 and 18A2.
    The portion of the body 12 receiving the carriage 14 is cylindrical, and has two internal radial projections 12C diametrically opposite extending towards the inside of the body 12. Each projection 12C has a first axial end wall 12C1, a second axial end wall 12C2, opposite in axial direction to the first axial end wall, and an axial wall 12C3 extending between the first and second walls of axial ends 12C1 and 12C2. The radial space between the carriage 14 and the radial projections 12C, along the axial walls 12C3, forms the passage 18A3 in which the ball 18B circulates to go from one chamber to the other. The space between the first axial end walls 12C1 and the carriage 14 forms the first chamber 18A1 while the space between the second axial end walls 12C2 and the carriage 14 forms the second chamber 18A2. In other words, the first chamber 18A1 is delimited by the first axial end walls 12C1 and the walls of the carriage 14 facing each other while the second chamber 18A2 is delimited by the second axial end walls 12C2 and the walls of the carriage 14 opposite. More particularly, in this example, the first chamber 18A1 is delimited by the first axial end walls 12C1 and the walls forming the "V" of the receptacle 15A of the part 14-1 of the carriage 14. Similarly, in this example , the second chamber 18A2 is delimited by the second axial end walls 12C2 and the walls forming the first "V" of the receptacle 15A of the part 14-2 of the carriage 14.
    The walls of the "V" of the receptacles 15B are not parallel to the axial end walls 14A1 and 14A2. In other words, the walls of the first and second chambers are convergent. More precisely, each chamber 18A1 and 18A2 has an inlet E and a bottom F, the walls being convergent from the inlet E towards the bottom F. In this example, considered in section along the axial direction X, 5 the first walls 12C1 axial end and the walls forming the "V" of the receptacle facing the first 12C1 axial end walls are inclined at an angle a relative to each other (see magnifying glass in Figure 2) . In this example a = 3 ° (three degrees of angle). Similarly, in this example, considered in section along the axial direction X, the second axial end walls 12C2 and the walls forming the "V" of the receptacle opposite the second axial end walls 12C2 are inclined at an angle a to each other. Of course, the angle a of the first chamber 18A1 and of the second chamber 18A2 can be the same or different.
    The carriage 14 being movable in the axial direction X relative to the body 12, the dimensions of the first chamber 18A1 and of the second chamber 18A2 vary depending on the relative position of the carriage 14 relative to the body 12. In particular , in FIG. 2, the first chamber 18A1 has its maximum dimensions (and its maximum volume) while the second chamber 18A2 is reduced to its minimum and has a zero volume. Conversely, in Figure 3E the second chamber 18A2 has its maximum dimensions (and its maximum volume) while the first chamber 18A1 is reduced to its minimum and has a zero volume. The diameter of the ball 18B is greater than the minimum width of the convergent formed by each chamber when the chamber has its maximum dimensions, so that the ball 18B cannot escape from the chamber through its bottom. Furthermore, in this example, depending on the relative position of the carriage 14 relative to the body 12, the passage 18A3 is closed on one side of an axial end 30 of the body or another by the carriage 14. Although heard according to a variant, the passage can remain open whatever the relative position of the carriage 14 relative to the body 12.
    The manual device 10 comprises in this example two strikers 20A and 20B. Considered in the axial direction, the ball 35 18B is disposed between the two strikers 20A and 20B. More particularly in this example, the carriage 14 is disposed axially between the two strikers 20A and 20B. In this example, the two strikers 20A and 20B are coupled in translation in the axial direction X by means of a rod (not shown) connecting them to each other. In this example, the strikers 20A, 20B strike the ball 18B via the open bottom 5 of each chamber 18A1, 18A2.
    The operation of the manual device 10 will now be described with reference to Figures 3A to 3E.
    Figure 3A shows the manual device according to the configuration of Figures 1 and 2, namely the first configuration where the first head 14A is in the use position while the second head 14B is in the retracted position. In this configuration, considered along the direction of gravity G, the first axial end 12A is below the second axial end 12B. The ball 18B is in the first chamber 18A1 and blocks the carriage 14 axially with respect to the body 12. In fact, the ball 18B is interposed, without play thanks to the converging shape of the walls of the first chamber 18A1, between the carriage 14 and a radial projection 12C of the body 12. Thus, when the user wants to use the first head, and presses it while writing on a substrate, it is locked in position thanks to the ball 18B, which thus blocks the movement of the carriage 14, and therefore from the first head 14A in the axial direction X then the first axial end 12A towards the second axial end 12B. Of course, the movement of the carriage 14, and therefore of the first head 14A, in the axial direction X from the second axial end 12B towards the first axial end 12A is blocked by a shoulder of the body 12 not shown. The carriage 14 being blocked relative to the body 12 and carrying the first and second heads, the heads 14A and 14B are respectively locked in the use position and in the retracted position.
    To go to the second configuration where the first head 14A is in the retracted position and the second head 14B in the position of use, it suffices to pass, considered in the direction of gravity G, the first axial end 12A above the second axial end 12B, as shown in Figure 3B. In this position, thanks to gravity, the striker 20A strikes the ball 18B, which has the effect of helping it to disengage from the walls of the first chamber 18A1. According to a variant, there is no striker, and the ball 18B emerges all by itself from the walls of the first chamber 18A1 under the effect of gravity, thanks to its relatively large mass, the ball 18B being in this metallic example.
    When the ball 18B is released, it moves under the effect of gravity G, leaves the first chamber 18A1 to go into the passage 18A3, as shown in Figure 3C. In this way, the carriage 14 becomes free to move in the axial direction X with respect to the body 12, since it is no longer blocked by the ball 18B.
    Under the effect of gravity G, the carriage 14 moves towards the second axial end 12B as shown in Figure 3D. It is noted that during this displacement the dimensions of the first chamber 18A1 are reduced until the volume of the first chamber 18A1 is zero while the volume of the second chamber 18A2 becomes non-zero and gradually increases.
    In FIG. 3E, the volume of the second chamber 18A2 is maximum, and the ball 18B, still under the effect of gravity G, has come out of the passage 18A3 and has entered the second chamber 18A2 to get stuck, without play, between the converging walls of the second chamber 18A2.
    During this movement, the carriage 14 has driven the first head 14A from the use position to the retracted position and the second head 14B from the retracted position to the use position. The manual device 10 is thus in the second configuration. The ball 18B blocking the carriage 14 relative to the body 12, the user can easily use the second head 14B which remains in position in particular when it presses against a substrate. In other words, when the user wants to use the second head 14B, and presses it against a substrate, it is locked in position thanks to the ball 18B, which blocks the movement of the carriage 14, and therefore of the second head 14B in the axial direction X from the second axial end 12B to the first axial end 12A. Of course, the movement of the carriage 14, and therefore of the second head 14B, in the axial direction X from the first axial end 12A towards the second axial end 12B is blocked by a shoulder of the body 12 not shown. The carriage 14 being blocked relative to the body 12 and carrying the first and second heads, the heads 14A and 14B are respectively locked in the retracted position and in the position of use.
    To return to the first configuration, it suffices to carry out the reverse movement, namely to place, considered in the direction of gravity G, the first axial end 12A below the second axial end 12B. Under the effect of gravity G the striker 20B then strikes the ball 18B which emerges from the second chamber 18A2, releases the carriage 14 which moves axially by driving the heads 14A and 14B, until the ball s' introduce into the first chamber 18A1 and blocks the carriage 14 relative to the body 12. We then find ourselves in the first configuration shown in FIG. 3A.
    4 shows a second embodiment of the manual device 10 ', identical to the manual device 10 according to the first embodiment, with the exception of the carriage. Thus, the other elements are not described again and their reference sign remains unchanged.
    In this second embodiment, there is not a single carriage but a first carriage 14-1 'and a second carriage 14-2' respectively carrying the first head 14A and the second head 14B. Thus, in the first configuration, when the first head 14A is in the position of use and the second head 14B in the retracted position, the first head 14A is locked in this position by means of the ball 18B while the second head 14B is not not locked in this position, the second carriage 14-2 'not being blocked by the ball 18B (while the first carriage 14-1' is blocked by the ball 18B). However, thanks to gravity, the second head 14B remains in the retracted position. Conversely, in the second configuration where the first head 14A is in the retracted position and the second head 18B in the use position, the second head 14B is locked in this position thanks to the ball 18B while the first head 14B is not locked in this position, the first carriage 14-1 'not being blocked by the ball (while the second carriage 14-2' is blocked by the ball 18B). However, thanks to gravity, the second head 14B remains in the retracted position.
    It should be noted that the choice of design of the manual device for one carriage or two carriages may be guided by requirements of space and / or robustness of the blocking of the carriage by the ball, but not necessarily. In fact, the variant with two trolleys makes it possible to produce larger interaction surfaces with the ball than in the variant with a trolley (the amplitude of axial movement required being less with two trolleys than with a trolley), thanks to 5 what blocking operated by the ball can be more robust.
    Although the present invention has been described with reference to specific embodiments, it is obvious that modifications and changes can be made to these examples without departing from the general scope of the invention as defined. by your claims. In particular, individual features of the various illustrated / mentioned embodiments can be combined in additional embodiments. Therefore, the description and the drawings should be considered in an illustrative rather than restrictive sense.
