    Description [0001] The present invention relates to an adjustment unit, in particular a group for adjusting the length of a flexible element, particularly a strap or a belt or the like, which are commonly used in the watch, jewelery, leather goods and clothing sectors.
    [0002] As is known, there are numerous types of watch straps, bracelets and the like made of metallic materials, such as gold or steel, and flexible materials such as leather, fabric or plastic.
    [0003] Straps of flexible material usually comprise a first end connected to a buckle provided with a barb or similar elements and a second end, arranged on the opposite side of the buckle, provided with holes arranged at a regular distance along the axis of development of the strap.
    [0004] To close these straps, the end provided with holes is inserted into the buckle and is locked by inserting the barb into one of the holes, chosen according to the morphological characteristics of the user.
    [0005] The straps described above, however, have the disadvantage that they cannot be adjusted according to lengths different from those defined by the holes present along the strap.
    [0006] In order to overcome the aforementioned drawback, it is known to use a punching pliers which allows further holes to be made in the strap in positions intermediate the existing holes so as to adapt the strap to the needs of the user.
    [0007] However, this solution entails the need to have to open and / or remove the strap to be adjusted and therefore its length cannot be adjusted if the strap and the object associated with it are worn.
    [0008] Furthermore, the provision of further holes to cover the intermediate adjustment distances does not always represent an aesthetically acceptable solution and, therefore, is not very suitable for being present on straps of particular value.
    [0009] As regards the straps in metallic material, they usually comprise a plurality of modular metal elements which are chained to one another in succession by means of rotation pins so as to form an articulated strap to which a closure is associated which allows you to wear it and take it off.
    [0010] In other embodiments, the strap can also be constituted by a flexible metal lamina provided with a closure suitable to allow it to be worn.
    [0011] The adjustment of the length of these straps can be performed only by expert personnel who removes or adds modular elements to the chain, based on the needs of the user.
    [0012] These straps therefore have a first drawback which is that in general they cannot be adjusted in length independently by the user but require the intervention of specialized personnel.
    [0013] Another drawback of the aforementioned straps is that they cannot be adjusted to lengths different from the multiples of the length of the single modular element.
    [0014] Very often, in fact, it is necessary to adjust the length of a strap or belt based on temporary needs.
    [0015] For example, in summer it may be necessary to increase the length of a strap to compensate for a slight swelling of the wrist due to the increase in temperature.
    [0016] In other cases, for example in the case of watch straps that are worn over the suit during scuba diving, it may be necessary to reduce the length of the strap to prevent it from slipping off the wrist due to the increased pressure that during the dive compresses the suit.
    [0017] These adjustments are fine type adjustments of a per se reduced entity but whose merit is to allow the user to wear the strap and / or the belt in a more comfortable situation.
    [0018] In order to carry out these fine adjustments, the use of a device comprising tubular connecting and connecting means which allow to vary the length of the strap by applying a force along the direction is known from US 9 198484. of extension of the strap itself and the action of elastic return means.
    [0019] Further devices for the aforesaid adjustment are described in the documents EP 0 737 427c and CH 695 656 where this adjustment is carried out by means of a release button which allows to vary the length according to two predefined measurements.
    [0020] However, the length of the straps or belts cannot be adjusted using the devices described above when the strap or belt to which they are attached are worn by the user because their use implies the need to open the strap or belt with consequent waste of time and greater complexity in the execution of the adjustment operation.
    [0021] The present invention intends to overcome all the limitations and drawbacks indicated.
    [0022] Specifically, it is an object of the invention to provide an adjustment unit, in particular a group for adjusting the length of flexible elements, for example straps and / or belts, which allows fine adjustment of their length to be performed so as to ensuring greater comfort for the user.
    [0023] It is another purpose for the adjustment unit of the invention to allow the adjustment operation to be carried out on these flexible elements without the need for the user to open and / or remove them.
    [0024] It is a further object that the regulation unit of the invention can be used on flexible elements of any type and made with any material.
    [0025] Last but not least, the purpose of the invention is to provide an adjustment unit which can be arranged in any position along the development of the flexible element to which it is applied.
    [0026] The objects listed are achieved with the realization of the adjustment group of the invention as described in the main claim to which reference will be made.
    [0027] Other features of the adjustment assembly are described in the dependent claims.
    [0028] Advantageously, the use of the adjustment group of the invention improves the performances offered by the flexible element to which it is applied, making it more suitable to the different conditions of use.
    [0029] The objects and advantages listed and other advantages which will eventually be mentioned hereinafter will be highlighted during the description of preferred embodiments of the invention which are given by way of non-limiting example, with reference to the figures shown in the enclosed drawings in which: fig. 1 and 2 show the adjustment unit of the invention in two different adjustment positions applied in an intermediate position to a flexible element, in particular a strap; fig. 3 and 4 show the adjustment unit of the invention in two different adjustment positions applied to an end of a flexible element and to its closure element; fig. 5 represents the axonometric exploded view of the regulation group of the invention; fig. 6 represents a plan view of the adjustment unit of the invention arranged in a position of regulation; fig. 7 represents the section of fig. 6, executed according to the section plan VII-VII; Fig. 8 represents the section of fig. 7 performed according to Section VIII - VIII; fig. 9 represents the section of fig. 8 when the adjustment unit of the invention is arranged in another adjustment position; fig. 10 and 11 show enlarged details of the sections respectively of fig. 8 and of fig. 9; fig. 12 represents the section of fig. 9 when the invention adjustment group is arranged in the elongation position; fig. 13 represents the plan section of fig. 12 with the adjustment unit constrained in the extended position; Figs.14 and 15 show the plan section of a variant embodiment of the adjustment unit of the invention arranged in two different adjustment positions.
    [0030] The regulation group of the invention is represented in the axonometric views of Figs. from 1 to 4 where it is indicated as a whole by 1 and where: - in figs. 1 and 2 the adjustment unit 1 is shown in two different adjustment positions and is applied to the ends Et and E2 of a flexible element indicated as a whole with E; - in figs 3 and 4 the adjustment unit 1 is shown in two different adjustment positions and is applied to an end E1 of the flexible element E and to the closure C of the same flexible element E.
    [0031] The flexible element E can be of any type and can be made with any material, for example leather, fabric, steel or precious metals in general.
    [0032] The flexible element E can therefore be a watch strap or a belt or any other similar object for which it is necessary to adjust its length.
    [0033] Still with reference to figs from 1 to 4 it can be observed that the regulation unit 1 of the invention comprises a first element 2 having first joining means 3 for the connection to a first end E2 of the flexible element E or to the closure C of which the flexible element E is provided and a second element 4 having second connecting means 5 for connection to a second end E1 of the flexible element E.
    [0034] It can be seen that the aforesaid elements 2 and 4 are arranged adjacent to each other one after the other according to the length of the flexible element E and the first element 2 has a substantially U-shaped profile which delimits a shaped area 2a configured to accommodate the second element 4.
    [0035] With particular reference to figs from 5 to 13 it can be observed that in the mutually adjacent ends of the elements 2 and 4 there are sliding means 6 which allow the elements to be moved relative to one another according to the length of the flexible element E to vary their distance and lengthen shorten the flexible element E itself, as will be better explained below.
    [0036] As regards the sliding means 6, for example with reference to fig. 5, it can be seen that they comprise an undercut area 2b formed in each end of the first element 2, configured to receive the corresponding end 4b of the second element 4.
    [0037] Finally, it should be noted that the adjustment unit 1 also comprises connection means, indicated as a whole with 7 and particularly visible in the exploded view of Fig. 5, which are able to join the elements 2 and 4 together, arranging them close to the sliding means 6 and therefore substantially coupling each end 4b of the second element 4 in the respective undercut 2b of each end of the first element 2.
    [0038] The aforementioned connection means 7 which are also visible in each of the fig. from 6 to 13, according to the invention, comprise: - at least one operating push-button 10, operable by the user of the flexible element E, which is slidably and elastically associated in a housing 10a formed at the end of the first element 2; - at least one guide pin 8 which connects the operating button 10 to the end of the first element 2; - at least one junction pin 9 which connects the operating button 10 to the adjacent ends of the first element 2 and of the second element 4; - at least one shaped seat 11 present in the second element 4 and provided with abutment means 12 suitable for stably fastening the junction pin 9 to the second element 4 and guide means 13 suitable for slidingly connecting the junction pin 9 to the second element 4 .
    [0039] It is particularly observed in the exploded drawing of Fig. 5 that the second element 4 is composed of two half-shells 4c and 4d which, when joined by the screws 4e, define between them the shaped seat 11 with the respective abutment means 12 and guide means 13. In particular for the button maneuver 10 are possible: - a first position indicated with A and observable for example in fig. 11 in which the operating push-button 10 is pressed towards the bottom of its housing 10a and arranges the joint pin 9 to be slidably received in the guiding means 13 to allow the displacement of the elements 2 and 4 in mutual approach and / or withdrawal; - a second position indicated with B and observable for example in fig. 10 in which the operating button 10 is released and allows the junction pin 9 to be constrained to the abutment means 12 to prevent the displacement of the elements 2, 4 in mutual approach and / or withdrawal.
    [0040] According to the embodiment which is described herein with reference to the figs. from 5 to 13 the adjustment unit of the invention comprises two operating push-buttons 10 each of which is received in a respective housing 10a formed in one end of the first element 2 and is connected to the guide pin 8 and at the first end 9 a of the junction pin 9, both previously mentioned.
    [0041] The junction pin 9, as can be observed, is also provided with a second end Se, opposite to the first end 9a, which is received in the shaped seat 11 of the second element 4 and in which the aforementioned matching means are present 12 and guide means 13 which are configured to cooperate with the second end 9c of the joint pin 9.
    [0042] More particularly, it can be observed that the junction pin 9 has the first end 9a fixed in a first hole 23 present in the operating button 10, the second end 9c, opposite to the first end 9a, which as described above is configured for be inserted inside the shaped seat present in the second element 4 and an intermediate area 9b, comprised between the first end 9a and the second end 9c, which is slidably coupled in a through hole 24 present in the first element 2.
    [0043] Finally, externally to the junction pin 9 and comprised between the operating button 10 and the first element 2, there is at least a second elastic element 13b able to make the movement of the operating button 10 within its housing 10a compliant when is pressed and released.
    [0044] It is also noted that the guide pin 8 which connects the operating button 10 to the end of the first element 2 has a first end 8a which is fixed in a first hole 21 present in the operating button 10 and a second end 8b , arranged on the opposite side of said first end 8a, which is associated with at least a first elastic element 13a, also adapted to make the movement of the operating button 10, which is inserted in a second hole 22 present in the first, elastically yielding. item 2.
    [0045] Ultimately the first elastic element 13a associated with the guide pin 8 and the second elastic 13b associated with the joint pin 9. both interposed between the operating button 10 and the first element 2, serve to make the movement of the button elastic. of maneuver 10 in the respective housing 10a when pressed and released.
    [0046] As far as the abutment means 12 is concerned, particularly with reference to figs. of details 10 and 11, that they comprise two or more shaped holes 12a which are formed in the shaped seat 11 of the second element 4, are arranged side by side and spaced apart from one another and are connected to each other by joining slits 15 which realize the aforementioned means guide 13.
    [0047] As regards the junction slots 15 they are configured to slidably accommodate the second ends 9 of the junction pin 9 when the operating button 10 is pressed towards the bottom of the housing 10a.
    [0048] Furthermore each of the shaped holes 12a is configured to receive a shaped core 16 congruent to it which is connected to the second end 9c of the junction pin 9, from which it protrudes peripherally to constrain the junction pin 9 to the second element 4 when the maneuver button 10 is released.
    [0049] As regards in particular the shaped holes 12a and the shaped core 16, they are mutually congruent since they have cylindrical shapes of the same diameter.
    [0050] Furthermore the junction pin 9 also has a cylindrical shape and its diameter is less than the diameter of the shaped holes 12a and of the shaped core 16 and substantially the same and in any case not greater than the width of the junction slits 15.
    [0051] Operationally, when the operating push-button 10 is at rest with the elastic elements arranged in the expanded position which is observed in figs. 6, 8 and 10, each shaped core 16 of each junction pin 9 is housed inside a respective shaped hole 12a so that the first element 2 and the second element 4 are constrained respectively in a stable manner and cannot move relatively long the sliding means 6.
    [0052] They are therefore in the approached position shown in the aforementioned fig. 6, 8 and 10.
    [0053] When the operator intends to modify the length of the flexible element E he presses the operating buttons 10 which move towards the bottom of the respective housings 10a causing the shaped cores 16 to come out of the respective shaped holes 12a as shown in the figures . 9 and 11.
    [0054] In this situation the junction pins 9, particularly their second ends 9c, are made free to slide along the junction slots 15 and allow the reciprocal displacement of the elements 2 and 4 which are arranged in the configuration shown in fig. . 12 with consequent lengthening of the flexible element E.
    [0055] If at this point the operating buttons 10 are released, the elastic recovery of the elastic means with which they cooperate brings them back to the initial rest position in which the movement of the junction pins 9 causes the insertion of the shaped cores 16 from the respective shaped holes 12a as shown in fig. 13.
    [0056] In this situation the elements 2 and 3 are blocked in the position reached in which the flexible element E is elongated. The displacements described are indicated by the arrows shown in the respective drawings.
    [0057] Starting from the situation in fig. 13 and by repeating the same maneuvers described above, the elements 2 and 4 can be brought closer together in the configuration of fig. 6 and 8.
    [0058] In the embodiment described herein, there are only two stop means 12 consisting of two shaped holes 12a connected to each other by means of guide means 13 which are constituted by a single guide slit 15 and therefore allow only two positions of the elements 2 and 4 that make up the adjustment group 1.
    [0059] Obviously, embodiments are possible in which the abutment means 12 are provided with several shaped holes 12a in which case for the elements 2 and 4 which make up the adjustment unit 1, more than two adjustment positions will be possible at distances between them. different.
    [0060] From what has been described it can therefore be understood that the regulation group of the invention achieves all the prefixed purposes.
    [0061] In particular, the adjustment unit of the invention allows fine adjustment of the length of the flexible element to ensure greater comfort for the user who can adapt the circumference of the flexible element to its own needs.
    [0062] A further object is also achieved, as far as has been described, that this adjustment operation is simple and can be carried out by the user himself while keeping the flexible element worn.
    [0063] For the adjustment unit of the invention it is possible a variant embodiment which is represented in two positions in the figs. 14 and 15 where the regulating unit is indicated as a whole with 100 and differs from the regulating unit described above only because it is provided with a single operating button 110 slidably sliding and received in the respective housing 110a formed in one end of the first element 102 which is connected to the guide pin 108 and to a first end 109a of the joint pin 109, which, differently from the previously seen embodiment, extends along the second element 104 between two shaped seats 111 each of which is present in one of the ends of the aforesaid second element 104.
    [0064] Also in this embodiment, inside each of the shaped seats 111 there are the abutment means 112 and the guide means 113 constituted respectively by shaped holes 112a and by joint slots 115 which cooperate with corresponding associated shaped cores 116 to the joint pin 109.
    [0065] Operation takes place in a manner analogous to what has been said for the embodiment described above in this case by acting on the single operating button 110.
    [0066] Obviously also the adjustment unit 100 of the executive variant now described achieves all the purposes of the invention. In the executive phase, modifications and variations may be made to each of the embodiments of the adjustment group of the invention which have not been described in the patent text and which have not been represented in the respective figures.
    [0067] However, it is understood that if these possible modifications and / or variations should fall within the scope of the following claims, they must certainly be considered protected by the present patent.
