Description

Technical Field

[0001] This invention relates to a wearable object comprising a housing and a chain attached to the housing, the wearable object being intended to be worn on a user's wrist. More specifically, this invention relates to an attachment device for removably attaching the chain to the housing of the wearable object, the attachment device enabling the assembly and removal of the chain without the use of tools.

[0002] More specifically, the present invention relates to a watch comprising a case and a bracelet, the bracelet being attached to the case via an attachment means for removably attaching the bracelet to the case. Background Technology

[0003] The attachment devices used to attach the chain to the watch case are typically quite large in terms of the number of different parts required for assembly, the complexity of these parts, and the difficulty of manufacturing them.

[0004] In particular, the ends of each strand of the bracelet and the watch case must be specially shaped and machined to enable assembly. Furthermore, assembling these different components is quite time-consuming and therefore expensive.

[0005] A common attachment device is based on the presence of two lugs or other protruding elements arranged on the outer periphery of the middle part of the watch case, with a crossbar inserted at the end of the chain strap, each end of which is inserted into a hole arranged at each lug.

[0006] This type of method of attaching the bracelet to the watch case requires the use of specific tools to replace the bracelet. Therefore, if a user wants to replace the bracelet due to wear or aesthetic reasons, they usually have to have it done by a professional. This process is time-consuming and incurs a cost.

[0007] From an industrial perspective, during the manufacture or finishing of a watch case, lugs or other components protruding from the outer periphery of the central component hinder the automation of many operations. Therefore, some operations need to be performed manually to avoid damaging the lugs or other protruding components.

[0008] Attachment devices for facilitating the replacement of watch chains are known. However, these attachment devices are typically complex to manufacture and require insertable components, such as springs or straps, between the chain and the watch case to ensure the chain is locked in place.

[0009] Furthermore, attachments that provide simplified bracelet replacement require extensive modifications to the watch case and / or bracelet, which do not benefit the manufacturing methods of these components at all, resulting in additional costs during the manufacturing process.

[0010] Therefore, in order to address at least one of the known limitations mentioned above, there is a need to improve the attachment mechanism for removably attaching the chain to the watch case—more generally, to the wearable object. Summary of the Invention

[0011] Against this backdrop, the object of the present invention is to provide an attachment device for removably attaching a chain to the housing of a wearable object, having a simple and cost-effective design that eliminates the need for any parts inserted between the chain and the housing of the wearable object to ensure a resilient connection and locking. Therefore, the present invention provides an "integrated" solution that eliminates the need for additional parts to assemble and lock the chain into place on the housing.

[0012] Another object of the present invention is to provide an attachment device that allows for the simple assembly and removal of the chain from the housing without the use of tools. Therefore, users can easily replace their chain when it wears out or modify its appearance without the need for professional assistance.

[0013] Another object of the present invention is to provide an attachment device that enables easy manufacturing of parts, allowing the chain and housing to be fully automated by conventional means without requiring any manual calibration of the attachment device.

[0014] The attachment device according to the invention makes it possible to provide a housing without lugs and protruding elements for assembling the chain in the middle part, which makes it possible to obtain a symmetrical housing that is easy to automate.

[0015] Therefore, the present invention relates to a wearable object comprising a housing having an intermediate component, a chain, and an attachment system for removably securing each end of the chain to the intermediate component. The intermediate component includes two longitudinal chambers configured to form a slide. Each end of the chain includes a fastening head having a shape complementary to the longitudinal chambers and configured to engage with one of the two longitudinal chambers by sliding to form the attachment system. The wearable object is characterized in that the fastening head includes a portion made of a viscoelastic material, and the attachment system includes a viscoelastic fitting device for locking the axial movement of the fastening head within the longitudinal chambers by the viscoelastic response of the portion. The viscoelastic fitting device is formed by the engagement of rigid locking protrusions disposed in each longitudinal chamber and configured to deform the portion (made of viscoelastic material) upon insertion of the chain. The locking protrusions are configured to fit within a recess formed in the portion made of viscoelastic material to lock the axial movement of the fastening head.

[0016] In addition to the features mentioned in the preceding paragraphs, the wearable object according to the invention may have one or more of the following additional features, either individually or in any technically feasible combination:

[0017] - The portion made of viscoelastic material is the end portion of the fastening head;

[0018] -The portion made of a viscoelastic material forms an end flange;

[0019] - The portion made of viscoelastic material is made of thermoplastic elastomer;

[0020] - The fastening heads at both ends of the chain are made of thermoplastic elastomer;

[0021] - A recess is formed in the central region of the portion made of a viscoelastic material, and a locking protrusion is centered longitudinally within the longitudinal cavity;

[0022] - The chain has two strips, each strip including a fastening head forming the end of the strip, and the fastening head is integrally formed with the strip of the chain;

[0023] - The locking protrusion is integrally formed with the intermediate component;

[0024] - The intermediate component is made of thermoplastic material, preferably polyamide 11;

[0025] - The size of the fastening head is larger than the size of the longitudinal chamber; therefore, when the fastening head is inserted into the longitudinal chamber, the portion made of viscoelastic material will inevitably undergo additional deformation.

[0026] - The attachment system is configured to allow assembly and removal of the chain via the first or second end of the longitudinal chamber;

[0027] - The longitudinal chambers extend on two arcuate sections of the intermediate component located at the 6 o'clock and 12 o'clock positions on the housing.

[0028] Advantageously, a wearable object is a watch. Attached Figure Description

[0034] In all the accompanying drawings, the same elements have the same reference numerals unless otherwise specified. Detailed Implementation

[0035] Figure 1 A first perspective view showing an exemplary embodiment of a wearable object 10 according to the present invention is shown. The wearable object 10 is herein in the form of a clock, such as a watch intended to be worn on a user's wrist. It should also be understood that the wearable object 10 can be, for example, a pedometer, a heart rate monitor, or any other wearable object intended to be worn by means of a strap—for example, worn on the wrist.

[0036] Figure 2 A second perspective view showing an exemplary embodiment of the wearable object 10 according to the present invention is shown, wherein the chain strap is shown not assembled in the intermediate component.

[0037] The wearable object 10 includes a housing 20, which is designed to house, for example, a watch movement (not shown here for clarity). The watch movement carries and drives a device for displaying information—such as the current time.

[0038] The housing 20 includes an intermediate component 21, which is closed at the bottom by a back cover 23 and at the top by a crystal 22. The housing 20 may also include a bezel (not shown) mounted on the intermediate component 21 and capable of carrying the crystal 22; the bezel may or may not be rotatable.

[0039] The housing 20 is defined, for example, in Figure 1 The visible main plane P has a transverse axis x and a longitudinal axis y. An axis z extends perpendicularly to the main plane P and defines the thickness of the housing 20. The main plane P is advantageously parallel to the planar portion of the plate included in the watch movement.

[0040] In the illustrated embodiment, the horizontal axis x is parallel to the axis from point 3 to 9, and the vertical axis y is parallel to the axis from point 6 to 12.

[0041] The housing 20 shown by way of example has a generally circular shape. However, the housing 20 may have other known embodiments without departing from the scope of the invention.

[0042] The wearable object 10 also includes a flexible, removable chain 30, the two ends of which are designed to be removably attached to the intermediate part 21 of the housing 20 via the attachment system 100. The attachment system 100 allows the chain 30 to be secured to the housing 20 without tools, locked in place, and the chain 30 to be easily replaced.

[0043] The attachment system 100 allows the chain 30 to be assembled in a reversible manner through viscoelastic deformation. Therefore, the attachment system 100 according to the invention is particularly advantageous compared to systems with irreversible snap-fit ​​engagements, where the irreversible snap-fit ​​engagement requires the destruction or damage of at least one of the elements constituting the attachment system when the chain 30 is removed from the housing 20.

[0044] The attachment system 100 according to the invention is an alternative embodiment of a snap-fit ​​type attachment system. This attachment system, utilizing viscoelastic deformation, particularly simplifies its production by leveraging the viscoelastic deformation properties of the chain. This makes the chain 30 easier to design and manufacture.

[0045] The chain 30 is presented in the form of two strips 30a, 30b connected to each other by a closing device (not shown), such as a hook, a release ring, or any other dedicated element for performing this attachment function of the two strips 30a, 30b of the chain 30 around the user's wrist.

[0046] According to an alternative embodiment, the chain 30 is formed from a single strip.

[0047] The intermediate component 21 includes two longitudinal chambers 110a and 110b, each longitudinal chamber configured to receive the end of each strip 30a, 30b of the chain belt 30, and more specifically, to receive fastening heads 31a, 31b forming the ends of each strip 30a, 30b of the chain belt 30. The first longitudinal chamber 110a... Figure 2 This is shown in more detail below.

[0048] Longitudinal chambers 110a and 110b are arranged in the intermediate member 21 and advantageously replace the attachment lugs typically used for attaching the chain belt 30. The longitudinal chambers 110a and 110b cooperate with the fastening heads 31a and 31b of the strips 30a and 30b of the chain belt 30 to form the attachment system 100 of the chain belt 30.

[0049] Therefore, it is observed that the intermediate component 21 of the housing 20 according to the invention does not include a protruding element for attaching the chain belt 30. Thus, the manufacture of the housing 20 can be carried out in a fully automated manner.

[0050] Longitudinal chambers 110a and 110b are formed at two opposing attachment portions, located on either side of the dial (not shown), and advantageously at 6 o'clock and 12 o'clock.

[0051] Longitudinal chambers 110a and 110b extend on two arcuate sections of the intermediate component 21 located at the 6 o'clock and 12 o'clock positions.

[0052] The longitudinal chambers 110a and 110b form a slide extending along the longitudinal axis, which forms a sliding axis XX. The sliding axis XX is parallel to the transverse axis x of the shell 20.

[0053] The longitudinal chambers 110a and 110b are configured to receive the fastening heads 31a and 31b of the strips 30a and 30b of the chain belt 30 and guide the fastening heads 31a and 31b to translate along the sliding axis XX during the assembly and removal of the chain belt 30.

[0054] Therefore, by sliding the fastening heads 31a and 31b in the longitudinal chambers 110a and 110b of the intermediate component 21, the strips 30a and 30b are assembled onto the intermediate component 21.

[0055] The longitudinal chambers 110a and 110b are through, meaning they are open at the first and second ends, allowing the chain 30 to be inserted and removed by sliding the fastening head through the first and second ends of the longitudinal chambers 110a and 110b—that is, the end located on the crown side (3 o'clock side) or the end located on the side opposite to the crown (9 o'clock side).

[0056] The fastening heads 31a and 31b of the strips 30a and 30b have complementary shapes that are suitable for being accommodated in the longitudinal chambers 110a and 110b and for engaging by sliding linearly along the sliding axis XX in the longitudinal chambers 110a and 110b.

[0057] Figure 3 A cross-sectional view of a portion of the wearable object 10 along the planes y and z is shown, so that the cross-sections of the longitudinal chambers 110a, 110b and the fastening heads 31a, 31b locked in the longitudinal chambers 110a, 110b can be illustrated.

[0058] It can be seen that the longitudinal chambers 110a and 110b and the fastening heads 31a and 31b have a roughly hook-shaped cross-section.

[0059] The longitudinal chambers 110a and 110b have a lower surface 111 defining the lower part of the chamber, a bottom 112 defining the upper part of the chamber, and an upper surface 113 defining the upper part of the chamber.

[0060] Advantageously, the longitudinal chambers 110a, 110b have an undercut portion for locking the movement of the chain belt—excluding translational movement along the sliding axis XX corresponding to the longitudinal axis of the longitudinal chambers 110a, 110b.

[0061] In the exemplary embodiment shown, undercut portions are formed in the upper surface 113 of the longitudinal chambers 110a and 110b, and the lower surface 111 is planar.

[0062] In an alternative embodiment (not shown), an undercut portion may be formed in the lower surface 111 of the longitudinal chambers 110a, 110b, and the upper surface 113 may be planar.

[0063] In an alternative embodiment (not shown), the lower surface 111 and the upper surface 113 of the longitudinal chambers 110a and 110b may each have an undercut portion.

[0064] Each fastening head 31a, 31b has an end flange 311 forming the free end of the fastening head 31a, 31b, the end flange 311 having an end face 312 intended to be positioned facing or contacting the bottom 112 of the longitudinal chambers 110a, 110b.

[0065] Compared with the strips 30a and 30b of the chain belt 30, the end flange 311 has a larger material thickness.

[0066] This configuration advantageously allows the strips 30a and 30b to translate within their respective longitudinal chambers 110a and 110b by sliding along axis XX, while simultaneously hindering other degrees of freedom through the presence of end flanges 311 at the ends of the fastening heads 31a and 31b, which have a greater material thickness than the strips 30a and 30b. The flanges 311 are shaped to mate with the undercut portions of the longitudinal chambers 110a and 110b and form a means for retaining the chain 30.

[0067] Obviously, other embodiments can also be considered. For example, the longitudinal chambers 110a, 110b and the complementary fastening heads may have circular, L-shaped, T-shaped, C-shaped cross-sections, etc.

[0068] The attachment system 100 also includes a viscoelastic assembly device for securing and locking the axial movement of each strip 30a, 30b in the longitudinal chambers 110a, 110b of the intermediate member 21, so as to lock the position of each strip 30a, 30b in a so-called locked position.

[0069] The viscoelastic assembly device is configured to achieve a reversible viscoelastic assembly of the fastening heads 31a, 31b of the strips 30a, 30b on the intermediate member 21 by viscoelastic deformation of the fastening heads 31a, 31b—more specifically, the end flanges 311.

[0070] For this purpose, at least the end flanges 311 of the fastening heads 31a and 31b are made of a material that allows viscoelastic deformation when the strips 30a and 30b are inserted into the housing 20.

[0071] The viscoelastic assembly includes a locking protrusion 210, such as a post or finger. Advantageously, the locking protrusion 210 is longitudinally centered relative to the sliding axis XX in each longitudinal chamber 110a, 110b. However, other locations for the locking protrusion 210 are also conceivable.

[0072] Figure 4 Show Figure 2 The wearable object 10 shown is illustrated in a cross-sectional view along the intermediate plane of the housing parallel to the planes x and y, showing the intermediate cross-section of the longitudinal chambers 110a, 110b and the fastening heads 31a, 31b, and in particular the locking protrusion 210 disposed within the longitudinal chambers 110a, 110b.

[0073] Locking protrusions 210 are formed at the bottom 112 of the longitudinal chambers 110a, 110b and protrude from the bottom 112 to form a barrier that prevents the assembly of the strips 30a, 30b of the chain belt 30.

[0074] Advantageously, the locking protrusion 210 is rigid.

[0075] Advantageously, the locking protrusion 210 is integrally formed with the intermediate component 21.

[0076] The locking protrusion 210 is configured to mate with the end face 312 of the end flange 311 of the fastening heads 31a, 31b, and causes the end flange 311 to undergo viscoelastic deformation when the chain 30 is assembled. Therefore, in order to assemble the chain 30, the user must resist a certain assembly resistance because the viscoelastic deformation of the end flange 311 is sufficient to ensure that the locking protrusion 210 passes through when the chain 30 is inserted into the longitudinal chambers 110a, 110b.

[0077] A recess 213 is formed at the end face 312 of the end flange 311 of the fastening heads 31a and 31b. The recess 213 is configured to receive the locking protrusion 210 and form a blocking device for preventing the axial movement of the strips 30a and 30b within the longitudinal chambers 110a and 110b. The recess 213 has a shape complementary to the shape of the locking protrusion 210.

[0078] The locking protrusion 210 engages with the recess 213 to form a viscoelastic assembly of the chain belt 30 and lock the axial movement of the fastening heads 31a and 31b. In order to remove the chain belt 30, the user must exert sufficient force to remove the locking protrusion 210 from the recess 213 and deform the end flanges 311 of the fastening heads 31a and 31b again.

[0079] Advantageously, the locking protrusion 210 and the complementary recess 213 have a chamfered or curved shape at the contact surface to facilitate the assembly and removal of the chain belt 30.

[0080] The viscoelastic assembly device according to the invention is configured to deform the end flanges 311 of the fastening heads 31a, 31b by compressing the material generally along the longitudinal axis y of the housing 20 toward the chain belt 30—more specifically, toward the strips 30a, 30b.

[0081] The fastening heads 31a, 31b of each strip 30a, 30b of the chain belt 30 are made of a material that is more flexible than the intermediate part 21 of the housing 20, so as to allow the end flanges 311 of the fastening heads 31a, 31b to deform during the assembly of the chain belt 30.

[0082] Advantageously, at least the end flanges 311 of the fastening heads 31a, 31b of the chain belt 30 are made of a thermoplastic elastomer of the TPV (thermoplastic vulcanizate), TPU (thermoplastic polyurethane), TPE (thermoplastic elastomer), or TPO (thermoplastic polyolefin) type. For example, at least the end flanges 311 of the fastening heads 31a, 31b can be made of Opti-Flex. TM Made.

[0083] For example, the fastening heads 31a and 31b of the chain belt 30 may be made of the same or different materials as the end flange 311, wherein the viscoelastic and hardness properties are the same or different.

[0084] For example, the strips 30a and 30b may be made of the same or different materials as the fastening heads 31a and 31b of the chain belt 30, wherein the viscoelastic and hardness properties are the same or different.

[0085] For example, intermediate component 21 is made of a metallic material or a polymer. Advantageously, intermediate component 21 is made of a thermoplastic polymer. For example, intermediate component 21 may be made of polyamide 11, also known as polyundecylamide or nylon 11.

[0086] Intermediate component 21 is advantageously a one-piece intermediate component. However, it is also possible to produce intermediate components assembled from multiple separately manufactured parts.

[0087] Advantageously, intermediate components made of polymers are integral intermediate components produced by injection molding.

[0088] The chain 30 is assembled onto the intermediate part 21 of the housing 20 in the following manner. Figures 4 to 6 Different assembly stages are shown.

[0089] exist Figure 4 In the first stage shown, each strip 30a, 30b is inserted into the longitudinal chambers 110a, 110b of the intermediate component 21.

[0090] Since the longitudinal chambers 110a and 110b are symmetrical, the chain 30 can be assembled via the first or second end of the longitudinal chambers 110a and 110b, that is, via the end located on the same side as the crown or via the end opposite to the crown.

[0091] exist Figure 5 In the second stage shown, each strip 30a, 30b is then aligned in the selected assembly direction (e.g., in...). Figure 5 (In the direction shown) XX slides along the sliding axis of the longitudinal chambers 110a and 110b into the longitudinal chambers 110a and 110b.

[0092] When the strips 30a and 30b are inserted, and when the locking protrusion 210 contacts the lateral end of the end flange 311, the user must apply force to cause viscoelastic deformation of the portion of the end flange 311 facing the locking protrusion 210, so as to allow the strips 30a and 30b to slide in the longitudinal chambers 110a and 110b until the locking protrusion 210 reaches the recess 213, so as to ensure that the chain 30 is locked by the viscoelastic response of the material at the end flange 311 that restores its initial shape.

[0093] Once the locking protrusion 210 is inserted into the recess, the chain 30 is immediately locked in place within the housing 20. This third locking stage... Figure 6 This is shown in detail in the text.

[0094] In order to unlock and remove the chain 30, the user must apply enough force to remove the locking protrusion 210 from the recess 213 and deform the end flanges of the fastening heads 31a, 31b again, especially the part of the end flange 311 facing the locking protrusion 210.

[0095] When the locking protrusion 210 is no longer in contact with the end flange 311 of the fastening heads 31a and 31b, the strips 30a and 30b can slide freely and be extracted from the longitudinal chambers 110a and 110b by translating the strips 30a and 30b along the sliding axis XX.

[0096] It should be noted that, since the end flange 311 is made of a deformable material, the thickness and rigidity of the end flange 311 must be determined to prevent the user from excessively deforming the end flange 311 by applying tension to the chain 30 along the longitudinal direction of the housing 20, thereby pulling the chain 30 out of the longitudinal chamber 110a. Therefore, with sufficient thickness, it will be ensured that the user cannot untangle the chain 30 by applying tension to the strips 30a, 30b.

[0097] According to an alternative embodiment (not shown), the fastening heads 31a, 31b—more specifically, the end flange 311—are slightly larger than the longitudinal chambers 110a, 110b. This requires additional deformation of the fastening heads when the strips 30a, 30b are inserted. In particular, such an alternative embodiment allows for increased force required to assemble and remove the chain by sliding.

[0098] The housing and system for attaching the chain to the housing according to the invention greatly facilitate the method of manufacturing the housing because the housing has no attachment lugs and is completely symmetrical. Therefore, the manufacturing of the housing and the chain can be automated. Thus, in particular, the manufacturing cost of such components and such wearable objects is reduced by the absence of alignment operations on the housing and the absence of additional elements such as rods for attaching the chain to the housing.

[0099] The attachment system according to the invention advantageously avoids the use of additional or inserted components, such as rods, elastic clips, etc., between the chain and intermediate components, or eliminates the need for tools (whether specialized or conventional) to secure and / or remove the chain.

[0100] Furthermore, the attachment system according to the invention simplifies the replacement of the chain belt, making it easy to update the chain belt in case of wear, or to modify its appearance through a simple procedure, without using tools during chain belt removal and without damaging one of the components of the attachment system.

[0101] The invention has been described with reference to specific embodiments of the housing and the ends of the chain straps. However, it will be apparent that other embodiments, as well as embodiments derived from the described embodiments, are contemplated.
