Description

Technical Field

[0001] The present invention relates to jewelry and watchmaking, and more specifically to chains, necklaces and / or bracelets including bracelets for wristwatches. In one aspect, the present invention relates to links and / or clasps arranged to be incorporated into and / or removed from a chain.

Background Art

[0002] (Technical problem underlying the present invention) In the field of chains and bracelets for jewelry and watchmaking, it is desirable to be able to shorten or lengthen the chain by removing links from the chain, and also to be able to open the chain, for example when a buckle and / or clasp is not present.

[0003] It is an object of the present invention to provide a chain and / or link arranged to allow removal and / or addition of links to / from a chain and / or bracelet.

[0004] In the field of decorative jewelry and watchmaking, more specifically in the field of decorative chains, such as chains for necklaces or bracelets, the requirements for miniaturization and / or aesthetics constitute a significant constraint on the implementation of solutions for the purposes defined above. For example, a mechanism that allows for the removal of links from a decorative chain and / or bracelet must necessarily be made from very small parts (parts that are between 1 millimeter and 1 centimeter or 2 centimeters in size, depending on the part), which imposes challenges with respect to the manufacture of the parts, their assembly, and the reliability of the mechanism. To avoid the loss of bracelets and / or necklaces, it is important that the detachable links do not come undone accidentally, for example, by the link or chain getting caught on clothing and / or by collision with any object.

[0005] Furthermore, due to aesthetic considerations, it is advantageous to implement a mechanism that can be realized in a form that is little to no visible from the outside and does not necessarily include protruding structures such as working members that would interfere with the overall design of the chain links.

[0006] The following documents disclose clasps that are more or less relevant to the art of the present invention, but do not disclose links for chains according to the present invention: KR200334455Y1, US7082651, and US6484376. CN207055005U discloses a clasp for a belt.

[0007] The present invention provides links and / or clasps for chains, particularly decorative chains and / or jewelry, thereby achieving the above objectives. [Overview of the project]

[Modes for carrying out the invention]

[0093] Figures 1A, 1B, and 1C show a link 10 in the in-service position and / or service position according to one embodiment, the link comprising a first element 1 and a second element 2. In this in-service position, the first and second elements are joined to each other, preferably rigidly connected, thereby forming a closing link and / or loop of the chain, which can be formed with other links of the same or different types to form a chain.

[0094] The first element 1 and the second element 2 form a closed loop, thereby enclose and / or surround space 3, which forms or is a passage or hole. The passage allows other links to pass through and connect to the link or clasp of the present invention, like any other link, preferably in a typical chain-like manner. Thus, the link or clasp of the present invention can be incorporated into or connected to a chain.

[0095] Link 10 may be connected to other links that pass through the loop, as is customary for links in a chain.

[0096] The first and second elements each enclose or surround a portion of the closed space 3; that is, the two elements together form a link loop, and the link is necessary for it to function in this way. This feature distinguishes this embodiment from the apparatus shown in Figures 10A to 11B, in which the link is included in the second element and / or formed independently (Figures 10A and 10B), or there is no link enclosing the space (Figures 11A and 11B).

[0097] In one embodiment, two elements 1, 2 are the main elements that form and / or constitute a link. The link also includes a bolt 14 arranged to connect the two elements in a detachable manner.

[0098] Link 10, in the shown embodiment, the first element 1 comprises a body 1.1. The first element, in particular the body 1.1, comprises an opening 11. The actuation member 17, here in the form of a protruding push button, is positioned to be pressed down to unlock the first element relative to the second element, thereby allowing the first and second elements to move relative to each other and release the loop formed by the first and second elements. Releasing the loop allows the link to be separated from other links and / or added to other links, for example, a chain comprising the link of the present invention.

[0099] In the embodiment shown, unlocking allows the first and second elements to be completely separated.

[0100] The locking mechanism for the first and second elements will be described with reference to Figures 2, 3, 4, 5, and 6. Figures 1A to 1C illustrate the simplicity of the mechanism in terms of the design and / or appearance of the link from the outside. The actuating member 17 passes through the opening 11 and forms a push button that protrudes onto the outer surface of the first element and / or link. The user can easily operate the push button, for example, with their finger.

[0101] As shown in Figures 2-6, the body 1.1 of the first element 1 includes a housing 15, more precisely the first housing, which houses the bolt 14 and the insert 21 of the second element, resulting in a locking engagement (effect).

[0102] The housing 15 is formed at least partially by two channels 26, 27 (Figures 4A, 4B), the two channels 26, 27 are positioned perpendicular to each other and intersect inside the body 1.1.

[0103] In one embodiment, the channel is a hole, preferably a blind hole. The channel is preferably machined by drilling a hole in the body 1.1.

[0104] The first channel 26 opens to the outside through the first opening 11, and the second channel 27 opens to the outside through the second opening 12; therefore, the first opening and the second opening are separate openings within the body 1.1 in the shown embodiment.

[0105] Therefore, the first opening 11 and the second opening 12 provide access to the housing 15 through their respective channels. In the shown embodiment, the channels (blind holes) form the housing 15.

[0106] The bolt 14 is housed within the first channel 26 and comprises a head 17, the head 17 of which protrudes through the first opening 11 and comprises and / or comprises an actuation member that allows the bolt 14 to be actuated through the opening 11.

[0107] Inside the main body 1.1, the housing 15 has or forms a compartment. The dimensions and / or shape of the compartment are arranged to enclose and guide the bolt 14, thereby allowing the bolt 14 to perform linear, translational, and / or axial movement along its main axis. The enclosement and / or guidance is preferably defined by a first channel 26.

[0108] A return element 16, for example, a spring, preferably a cylindrical compression spring, is located within the housing 15, more specifically in a dedicated compartment 37 at the inner end of the channel 26, opposite to the opening 11, to extend the housing of the bolt 14 and propel the bolt axially and / or toward the opening 11.

[0109] As will be understood below, the return element 16 is positioned to facilitate the bolt to the locked position and / or to prevent accidental unlocking. In the embodiment shown, the housing 15 includes and / or is formed by different compartments, namely channels 26, 27 and recesses 37, which are intended to house and / or stabilize different parts, namely the bolt, insert 21 and spring 16, respectively.

[0110] The lock 14 is shown separately in Figure 2. Towards the first end shown on the left side of Figure 2, the bolt includes a head 17 that functions as and / or forms an actuating member. The other end (second end) includes a housing 34 and / or at least one bearing surface (Figure 5) to accommodate the end of a spring, where the spring constitutes a return element. The housing 34 may be, for example, a blind hole drilled axially into the lock, and this housing allows the spring to be supported and / or stabilized and / or to receive the end of a compression spring.

[0111] At or near the second end, the bolt also comprises and / or forms a cooperating region 31 and / or a locking portion of the lock. In the shown embodiment, the cooperating region comprises a cylindrical portion whose diameter is adjusted to allow locking with a cooperating structure 24, the cooperating structure 24 (the latter, latter) comprising a circular opening located in an insert 21 of the second element 2 of the link, the opening here oriented laterally with respect to the axial direction of the bolt 14 to receive the bolt 14.

[0112] The head 17 and the locking portion 31 are connected by a gap and / or connecting structure or region 33, the latter having dimensions reduced relative to the dimensions of the locking portion 31. The dimensions, particularly the diameter, are adjusted to allow unlocking and / or disengaging of the cooperative structure 24 along a defined clearance direction.

[0113] In the embodiments shown in Figures 1 to 6, the head 17 has a protruding structure with dimensions and / or shape, in this case a sphere, to facilitate manual operation. To enable guidance of the movement of the lock, the lock (latter) includes a guide region 32, the shape of which is complementary to the shape of the first channel 26, enabling guidance and / or sliding of the bolt along a defined displacement within the channel 26.

[0114] In the embodiment shown, the first channel is a cylindrical bore, and the guide region 32 is cylindrical in shape, and the guide region 32 (latter) is adapted to guide the axial movement of the bolt within the channel. The cooperating region 31, which is primarily for locking, can also serve as a guide toward, for example, the inner end of the channel 26.

[0115] The lock 14 further includes a collar 36 that defines a recess 38 that separates the head 17 from the gap region 33.

[0116] In the embodiments shown in Figures 1 to 6, different regions and / or different parts of the component forming the bolt are formed in a simple manner. The bolt 14 can be manufactured from a cylindrical pin, which is machined to include a defined region with a reduced diameter.

[0117] Here, the diameters of the guide region 32, the collar 36, and the locking structure 31 are, for example, the same as the diameter of the original pin. The gap region 33 and the recess 38 have a reduced diameter compared to the diameter of the original pin and can be machined into the pin to form the bolt 14. Furthermore, it should be noted that collar 36 is not mandatory, and there are other methods or arrangements for achieving bolt retention within housing 15, as will be described later with reference to Figure 8.

[0118] The second element 2 of the link shown in the figure forms an open O-shape, open circle, or open loop resembling the letters omega (Ω) or horseshoe, and its arms form a first end 41 and a second end 42. At least one of these ends, particularly the first end 41, preferably both, is provided with or forms an insert 21. The insert 21 is configured to be inserted into the first element 1 to position the insert within the housing 15, preferably through a second opening 12.

[0119] The insert 21 comprises one or more structures configured to lock the insert within the housing 15, more specifically, to allow the insert to cooperate with a bolt. The insert comprises, in particular, an opening or passage, in this case a circular hole, oriented to allow the bolt 14 to pass through when the insert is placed within the housing 15. The passage forms a cooperating structure 24 positioned to cooperate with the cooperating area 31 of the bolt, thereby locking the insert within the housing 15 as the bolt passes through the opening, in accordance with the conventional operation of locking.

[0120] The insert 21 further comprises a second passage 23 formed within the end 41, more specifically in the first passage 22, here as a notch and / or recess 23. The second passage 23 is preferably oriented perpendicular to the direction of the lock. This passage connects or opens the first passage 22 to the outside.

[0121] In the embodiment shown, the second passage 23 creates a fork-shaped end at the end 41. Instead of the second passage, the cooperative structure may be provided as a rim, for example, produced by cutting, which forms and / or defines the second cooperative structure. The second passage may not be present as an insert passage and / or may be defined together with the first element by an assembly formed by the geometric shape and / or shape of the housing 15 and the geometric shape and / or shape of the insert 21.

[0122] The second passage 23 has the same dimensions and / or shape as, or slightly larger than, the void area 33 of the bolt 14. In contrast, the dimensions and / or shape of the passage 23 are such, where appropriate, that they do not allow the locking structure 31 to pass through, taking into account the orientation of the insert when the insert is inserted into the second channel 27.

[0123] It should also be noted that the retaining portion 35, formed by the retaining clip, is fitted onto the bolt, more precisely into the recess 38, to prevent the lock from moving in the axial direction. The retaining portion 35 forms a shoulder on the lock. This shoulder protrudes beyond the outer surface of the bolt, particularly with respect to the guide region 32, forming a contact surface 39 (Figure 2). This contact surface is preferably adjacent to the guide region 32. Since the retaining portion 35 moves with the bolt 14, it forms a travel-restricting stop portion.

[0124] To assemble the bolt 14 into the housing 15, first the spring 16 is placed in its dedicated compartment 37 at the bottom of the blind hole 26. It can be inserted through either the first opening 11 or the second opening 12. The bolt 14 is preferably inserted into the channel 26, preferably through the first opening 11. The channel 26 forms a guide structure for the bolt, and inserting the bolt through the second opening 12 is not possible in the shown embodiment. Next, the retaining portion 35, which is a retaining clip or a type of washer or ring, is placed in the recess 38 of the bolt by inserting it through the second opening 12. To precisely position the retaining portion 35 on the bolt, it is usually necessary to push the bolt slightly into its housing, i.e., push the head 17, as in the case of operation during unlocking.

[0125] The retaining portion 35 forms an end stop portion 39 positioned to abut against the inner edge 29 (Figure 4B) of the housing 15, where the housing 15 is formed by the intersection of a first channel 26 and a second channel 27. Thus, the retaining clip holds the bolt within the housing 15 and / or within the channel 26.

[0126] As shown in Figures 4A and 4B, the actuation member 17 is a push button intended to be pressed down to move from the locked (or stationary) position shown in Figure 4A to the actuation and / or unlocked position shown in Figure 4B.

[0127] In the locked position, the insert 21 is held by the bolt and its cooperating region 31 engages with a cooperating structure 24 provided in the insert, so that it cannot exit the second opening 12. In the shown embodiment, the cooperating region 31 is a cylindrical portion of the bolt that fills the hole and / or passage, the latter (hole and / or passage, latter) which constitutes or comprises the cooperating structure 24.

[0128] The shape and dimensions of these cooperating structures (or parts) produce locking. The cooperating structure 24 of the insert aligns with the notch and / or passage 23, but the notch and / or passage 23 (the latter, latter) is made narrower than the passage defined by the cooperating structure 24, so that the insert 21 locks into the housing 15.

[0129] When the actuating member 17 is actuated, the bolt moves along its axis, resulting in the separation of the cooperating region 31 and the cooperating structure 24. Thus, they are no longer aligned in the direction of movement of the insert 21, which corresponds here to the axis of the second channel 27.

[0130] As a result of the operation, the bolt 14 is further pushed into its housing and / or channel 26, and the return element is compressed. This movement aligns the bolt's gap region 33 with the passage 23. The gap region 33 is sized to pass through the passage 23. In this configuration, the bolt can no longer block the movement of the insert 21 and is therefore able to exit the housing 15 in motion guided by the second channel 27. The result of the displacement of the second element 2 relative to the first element 1 is complete separation of the first element 1 and the second element 2, as can be seen in Figure 2.

[0131] As shown in Figures 3 and 5, the first element 1 comprises a second housing 45 formed by a bore substantially parallel to the second channel 27. The second housing 45 is positioned to receive the second end 42 of the second element 2. The second insert 22 is positioned to form the second end, and in the shown embodiment, the second insert has the same shape as the first insert 21.

[0132] The second housing 45 does not include a bolt, and therefore the insert 22 formed by the second end 42 is not locked within this second housing. When the bolt 14 is in the depressed and / or unlocked position, the two inserts 21, 22 formed at each end of the second element can exit from the first housing 15 and the second housing 45, respectively, allowing the link to be released.

[0133] In the shown embodiment, the second end 42 and / or the second insert 22 have the same shape and / or structure as the insert 21 of the first end, including the cooperative structure and / or the shape corresponding to the first passage 24 and the second passage 23. In this embodiment, this is not necessary in principle, as these shapes do not serve any particular function. It is possible to form the second end 42 differently and / or omit the structure necessary for the cooperation between the insert 21 of the first end 41 and the lock. The second insert 22 can be, for example, cylindrical overall. In the shown embodiment, the first and second inserts are made identically and / or the second insert 22 is a mirror image of the first insert 21. This facilitates the use of the link, as a user who wishes to lock the first and second elements does not need to worry about any particular orientation of the second element relative to the first element. The link can be locked in either the first insert 21 or the second insert 22, which are placed in the housing 15 via the channel 27.

[0134] In Figure 2, reference numerals 50, 51, and 52 indicate that the body 1.1 of the first element 1 can be segmented into three consecutive structures. The first support structure 51 is positioned to receive and accommodate the first end 41 (or first insert 21) of the second element, and the second support structure 52 is positioned to receive and accommodate the second end 42 (or second insert 22) of the second element. The first and second support structures are connected by a connecting structure 50, which in the shown embodiment is not significantly different from the first and second support structures but may be characterized by a reduced shape and / or size.

[0135] Other variants of the present invention can be directly inferred (deduce) by those skilled in the art. For example, the first channel 26 may be extended to join with the second housing 45, and a bolt may extend within this extended channel to provide a structure and / or shape that allows for locking and / or unlocking in cooperation with the second insert 22 and / or second end 42 of the second element. In this case, the bolt is positioned to lock and / or unlock simultaneously the inserts 21 and 22 at the ends 41 and 42 of the second element.

[0136] Link 10.1 according to a second embodiment is shown in Figures 7A, 7B, and 7C. In drawings showing other embodiments, the same reference numerals are used to indicate structural features corresponding to those already described herein. The difference between link 10.1 and link 10 shown in the aforementioned figures concerns the realization of the actuating member 17'. The latter (actuating member, latter, in link 10.1) does not form a prominent and / or protruding structure, but here it is formed by the guide region 32 and / or by the free end of the latter (latter) and / or more generally by the free end of the bolt 14'.

[0137] In the stationary / locked position, the actuarial member 17' may be substantially coplanar with the outer surface of the first element 11 or slightly recessed into the first channel 26. In this embodiment, there are no protrusions and / or projecting structural elements. More specifically, the bolt 14' in this embodiment does not protrude beyond the opening 11 of the first channel 26.

[0138] In this embodiment, the guide region 32 or its end functions as an actuating member 17', which can actuate the bolt 14'.

[0139] In preferred embodiments, particularly when the link of the present invention is not a clasp, the diameter of the first opening 11 is less than 4 mm, preferably less than 2 mm, more preferably 1.5 mm or less, for example, 0.9 to 1.4 mm. Its dimensions ensure that the actuator 17' can hardly be operated by hand with sufficient force to cause unlocking (to effect). The actuator 17' is preferably positioned to be pressed by a pointed, thin, and / or elongated object such as a needle, the tip of a screwdriver, or the tip of a pen.

[0140] The coplanar arrangement of the actuarial member 17' and the outer surface of the body 1.1 of element 1 has the effect of at least partially concealing the actuarial member 17'. Link 10.1 has the same external shape and / or the same external contour as other links of the same type that lack a locking mechanism. Thus, link 10.1 can be integrated into a chain of links having the same shape, and as a result, the links of the present invention fit perfectly into the chain and are generally not identifiable as specific links by an external observer.

[0141] In the embodiments shown in Figures 7A to 7C, the operating member 17' is positioned to close the opening 11. In this embodiment, the head 17' does not protrude from the opening 11 and / or is not positioned to protrude beyond the opening 11.

[0142] To open the links, the user and / or wearer typically inspects and / or orients each link closely, one by one, thereby exposing the opening 11 and, consequently, the actuation member 17'. For example, the user can identify a link 10.1 by selecting a viewing angle that allows them to see the opening 11 in which the actuation member 17' is located.

[0143] In the embodiments shown in Figures 8A and 8B, the bolt 14.3 is held within its housing 15 by means of a retaining ring 29.1, which is fixed to a seat 11.2 located on the first element 1, for example, by press-fitting, bonding, or welding. The bolt here includes a circular rim 39.3 that constitutes an end stop (travel limit stop), positioned to abut against the inner surface of the retaining ring 29.1 under the action of a force exerted by the return element 16. The seat 11.2 may be a hole and / or bore coaxial with the axis of the lock. The central opening 11.3 of the retaining ring 29.1 corresponds to the first opening 11 described above, through which the bolt head 17.1 can be actuated. In this embodiment, the separate retaining portion 35 shown in Figure 2 is not required. As in the first embodiment, the spring 16 is placed in the bottom of the bore 26, preferably in a recess 37 positioned to receive the end of the spring (Figure 5). Next, the bolt 14.3 is placed inside the housing 15. Finally, the retaining ring 29.1 is positioned here by press-fitting it onto the seat 11.2. Once placed on its seat 11.2, the retaining ring preferably maintains an integral and rigid connection to the body 1.1 of the first element 1. This embodiment illustrates an alternative method for retaining a bolt and / or preventing the bolt from separating from its housing.

[0144] Figure 9 shows an embodiment in which the link design of the present invention is adapted to constitute a clasp 10.3 for a jewelry item such as a necklace or bracelet in the form of a chain 30. Unlike the links of the first and second embodiments, link 10.3 has a shape that makes it distinguishable from the other links of the chain and / or identifies link 10.3 as a clasp of the chain. In the illustrated embodiment, clasp 10.3 comprises a first element 1.2 that forms two loops, each having a second element 2.1 and a third element 2.2. Generally, only the second element 2.1 (or only the third element 2.2) is arranged to separate when the actuating member 17.2 is operated. The other element, for example, the third element 2.2, may be formed integrally with the first element 1.2 and / or permanently connected to it. Elements 2.1 and 2.2 of the clasp are each connected to the loops and / or links 3.2 of the chain, preferably to the two end links 3.2 of the chain 30.

[0145] Figures 10A and 10B show a clasp 10.4 of an embodiment in which the second element 2.4 is provided with only a single insert 21.4. Element 2.4 comprises a closed loop 2.41 in the form of, for example, an O-shape, circular, elliptical, ring, or any chain link, the loop being provided with the insert 21.4, which is preferably positioned on the outer surface and / or around the closed loop.

[0146] Assuming the chain is laid flat so that the insert faces an adjacent link, the insert 21.4 is preferably oriented in the direction of extension of the chain, which includes the clasp 10.4.

[0147] The first element 1.4 has a first opening 11 and a second opening 12.4, but in this case, the second insert and / or second end of the second element 2.4 is absent, so the third opening may also not be present. The second opening 12.4 is oriented in the direction of extension of the chain so as to face the insert 21.4.

[0148] The bolt 14 is positioned and housed within the body of the first element 1.4, as will be described below with respect to the other embodiment, and operates in the same manner. Thus, the insert 21.4 comprises a cooperative structure and passages or recesses, allowing it to be held by the bolt 14 and separated from the bolt 14, as described above, depending on whether the actuation member 17 is actuated or not.

[0149] It should be further noted that in the first element 1.4, two structures may be distinguished. These two structures are a structure with a support or body 1.41 that accommodates the bolt and is arranged to receive the insert 21.4, and a structure with a (second) closed loop 1.42, which is preferably rigidly connected to the support 1.41 and may, but does not have to be, be formed integrally with the latter (latter, body) as described with respect to the clasp shown in Figure 9. The assembly formed by the first element 1.4 and the second element 2.4, including loops 1.42 and 2.41, preferably constitutes the clasp of this embodiment.

[0150] More generally, the embodiments shown in Figures 10A and 10B demonstrate the operation of the concept of the present invention having a single protruding end positioned to connect to a single insert 21.4 and / or a first element 1.4, the first element having a (single) opening 12.4 adapted to receive such an insert. This embodiment is preferably a clasp for jewelry, such as any jewelry comprising a necklace, bracelet, or chain.

[0151] Figures 11A and 11B show a connecting system 10.5 comprising a first element 1.5 and a second element 2.5 that can be rigidly connected to each other, according to the first and second elements of the link and clasp of the previous embodiment. In system 10.5, the second element 2.5 is a connecting device adapted to be attached to a strand of a bracelet by means of, for example, a spring bar (not shown). For this purpose, the second element comprises two lugs or lateral tabs 2.52, each having a hole 2.53, the two holes being positioned opposite each other to receive the end of a spring bar and to firmly hold the spring bar. The two lateral tabs 2.52 are positioned on a lateral bar 2.11 and connected thereto.

[0152] Spring bars can be placed at the ends of the bracelet strands so as to allow the bracelet strands to connect to the second element 2.5.

[0153] A flat and / or non-cylindrical insert 21.5 is positioned on the lateral bar 2.5 on the side opposite to the side supporting the lateral tab 2.52.

[0154] The first element 1.5 comprises a body 1.51 in which an opening 12.5 is formed, the opening 12.5 providing access to a housing 15.5 and positioned to receive an insert 21.5 of the second element 2.5, more precisely the second element 2.5 (the latter, latter). The first element 1.5 further accommodates a bolt 14.5 having the same characteristics as described above, and in particular comprises a continuous area shaped to perform different functions, such as an actuating member 17.5, a sliding and / or guiding area 32.5, arrangements 35, 36.5 and 38.5 forming end stops for holding the bolt within its housing, a gap area 33.5, and a cooperating and / or locking area 31.5. The spring 16 is also housed in the housing 15.5 located in the first element 1.5, as described above.

[0155] The locking and unlocking of the first key 1.5 and the second element 2.5 by the operation of the operating member 17.5 functions as described above with respect to the other embodiment.

[0156] The first element 1.5 can be attached to a watch case or jewelry, for example, to be part of a clasp, or to be part of any connecting system for watch and / or jewelry components.

[0157] As can be seen, the present invention is advantageous in that it provides a chain link that can be conveniently opened and closed in a secure manner. The link or clasp may be realized with as few as five parts, as disclosed herein. In some embodiments, the link or clasp may, of course, have more parts, for example, for decorative purposes. Thanks to the small number of parts and the contribution of the overall configuration, the link or clasp can be assembled quickly and miniaturized. The actuation member can be concealed as shown in Figures 7A to 8B, but is still operable by the user from the outside.

[0158] Those skilled in the art will not encounter any particular difficulty in adapting the contents of this disclosure to their own needs, and in particular in implementing links for jewelry or watchmaking items, without departing from the scope of the present invention. It should be noted that adapting this teaching to construct other types of links for bracelets, necklaces, chains, or any other jewelry that does not necessarily involve chains will not impose any particular difficulty on those skilled in the art.

[0159] In one embodiment, the first and second elements may be connected by a hinge instead of being completely separable, for example. One end of the second element, preferably the second end 42, can be connected by a hinge to the first element 1, for example, to a second support structure 52 (Figure 2). In this case, the first element 1 is preferably positioned to allow pivotal movement of the first end 41 when the bolt is in the unlocked position. For example, it is possible to enlarge the second opening 12 and / or the second channel 27 to allow such pivotal movement.
