Description

Technical Field

[0001] The present invention relates to the field of devices for hooking small objects or sundry items to a wall or partition, particularly in the passenger compartment or luggage compartment of a motor vehicle. Background Art

[0002] Many devices are known for hooking objects or items in the passenger compartment or luggage compartment of a motor vehicle. These devices make it possible, for example, to hook a cup holder, a bottle holder, a telephone holder or any other object to the visible inner wall of a motor vehicle. Thus, these hooking devices can make it possible to store objects (such as those mentioned) so that they are easily accessible to the user, or to prevent them from being thrown around in the vehicle in the event of an accident or sudden braking.

[0003] Fixed hooks or loops can, for example, help to store and transport objects in a vehicle. However, these hooking devices must withstand considerable mechanical stress. The wall to which the hooking device is fastened may also not be robust enough with respect to the forces, which are increased by the cantilever arms and lever arms generated by the device and the user's manipulation of it. This is because the fastening wall is typically a polypropylene sheet 2.5 mm thick and subject to "blistering" or pulling-off phenomena. Summary of the Invention

[0004] The object of the present invention is to propose a system for fastening an object to a motor vehicle wall that is simple to use and low in cost, while making it possible to hold the object so that it is easily accessible to the user and is not thrown around in the event of an accident or sudden braking of the vehicle.

[0005] Accordingly, an object of the present invention is a system for fastening an object to a wall, the system comprising a convex element fastened to the wall and a concave element configured to be assembled with the convex element, the concave element being rigidly connected to the object, the system being characterized in that:

[0006] - the convex element includes a head protruding from the wall and includes a first collar extending over at least a portion of the periphery of the head, and

[0007] - the concave element includes a body provided with three claws that are connected to a prestressed return member, thereby allowing the claws to move relative to the body and grip the collar of the convex element in order to assemble the concave element with the convex element by alternating between a closed position and an open position.

[0008] Thus, the system is capable of firmly and reversibly fastening an object to the wall of a vehicle. As a result, a user can fasten an object (such as a phone holder or a cup holder) to the convex part previously fastened to the wall of the vehicle, so that the object is at its disposal without any risk of the object being thrown around in the vehicle in the event of an accident or sudden braking.

[0009] Once the concave element and the convex element are assembled together, the two elements are closely associated with each other such that there is no play between them, thus preventing any noise and / or cantilever that might weaken the system.

[0010] These three claws are capable of moving between an open position and a closed position, and the transition from one position to the other occurs by actuation of a prestressed return member. The closed position (or rest position) corresponds to the initial position adopted when the concave element is not fastened to the convex element, and also corresponds to the position adopted when the claws close again around the collar of the convex element after the concave element and the convex element are assembled. This closed position corresponds to the position adopted by the claws when the prestressed return member is not compressed or deformed. The open position is the position adopted by the claws in order to be able to assemble the concave element and the convex element. In this open position, the claws move away from each other such that they can pass around the collar of the convex element and then close again around the collar by adopting the closed position. This position corresponds to the position adopted by the claws when the prestressed return member is compressed or deformed.

[0011] When the user acts on the prestressed return member to drive the claws away from each other, or when the user moves the claws away from each other (for example by forcefully pushing the concave element against the head of the convex element) and the movement of the claws away from each other then drives the prestressed return member to deform, the claws can adopt the open position. Once the claws have passed over the collar, due to the prestressed return member returning to its initial position, the claws close again spontaneously.

[0012] The prestressed return member (preferably a spring) allows the claws to close again so as to spontaneously adopt the closed position once no pressure is applied to the claws and / or the prestressed return member.

[0013] The body of the concave element serves as a support for the claws, which are capable of moving relative to the body.

[0014] The collar can extend over a part of the periphery of the head or over the entire periphery of the head of the convex element. The collar forms one or more flanges that project from the head and enable them to act as hooks for the claws, which close around the one or more flanges again behind them. When the collar extends over a part of the periphery, it can form a single flange (the single flange extends such that all the claws can hook onto it), or form multiple flanges, for example one flange for each claw.

[0015] Other features of the present invention are described below, which can be considered individually or in combination.

[0016] The concave element may include a transmission part that allows the prestressed return member to deform to drive the movement of these claws and vice versa. Thus, the transmission part enables the deformation of the prestressed return member to be linked to the movement of the claws. Preferably, the pressure on the transmission part drives the movement of the part, preferably the translation of the part relative to the body, and this movement causes the deformation of the prestressed return member and the opening movement of the claws. The pressure can be applied by the user.

[0017] According to the first usage method, the pressure applied to the transmission part thus enables the claws to be opened and the prestressed return member to be deformed in order to assemble the concave element with the convex element. Then, once the concave element is assembled with the convex element, releasing the pressure that has been applied to the transmission part allows the prestressed return member to spontaneously return to its initial position while driving the transmission part, which also returns to its initial position. Then, the transmission part drives these claws, and these claws close around the collar.

[0018] When the deformation of the prestressed return element drives the movement of these claws and vice versa, the first claw and the second claw can perform a translation that moves them away from each other along a first axis E1 perpendicular to the deformation axis D1 of the prestressed return member, and the third claw can perform a movement along a second axis E2 parallel to the deformation axis of the prestressed return member.

[0019] Therefore, based on the deformation of the prestressed return member, the three claws open simultaneously, two claws open in a first direction but in opposite senses, and the third claw opens in a second direction so as to open a space between the claws that can receive the head of the convex element.

[0020] The axis E1 and the axis E2 particularly define the overall opening direction of the claws, which move away from each other towards the outside of the body, and the claws preferably move away from each other with a movement including translation.

[0021] The axis D1 defines the deformation direction of the prestressed return member, which is preferably compressed along a straight axis.

[0022] Each claw may include a pin. The first pin of the first claw can be inserted into the first slot of the transmission part, the second pin of the second claw can be inserted into the second slot of the transmission part, and the pin of the third claw can be inserted into the orifice of the transmission part. These slots and the orifice enable the claws to move according to the movement of the transmission part and thus the movement of the prestressed return member.

[0023] The two slots and the orifice enable the movement of the drive part (and thus the deformation of the prestressed return member) to be simply associated with the movement of the pawls by means of the pins. Thus, each of the three pins forms a guiding member for the pawls and an engagement element between the pawls and the drive part.

[0024] Preferably, the slot includes a notch at one end, which enables the pawl to be locked in the closed position. Thus, when the force applied by the user on the part protruding from the housing of the drive part is applied to compress the prestressed return member, the pin can only leave the notch to slide in the slot. This prevents the pawl from easily opening in the event of a collision.

[0025] When the deformation of the prestressed return member drives the movement of these pawls and vice versa, the first pin and the second pin can slide along the first slot and the second slot respectively, and the third pin can be translated by the drive part along the axis E2. According to a preferred embodiment, the first slot and the second slot extend in a divergent direction and diagonally with respect to the axis E1. Thus, the movement of the drive part enables the pins to move away from the center of the body or, conversely, towards the center by sliding the pins along the slots.

[0026] When the third pin is inserted into the orifice of the drive part, the third pin directly follows the movement of the drive part.

[0027] According to a preferred embodiment, the drive part moves along the axis D1 and, when the prestressed return member deforms, enables the pins to move away from the center of the body and thus open these pawls.

[0028] The pawls can be C-shaped parts, which are preferably formed integrally and include a first section and a second section parallel to each other, and a third section connecting the first section and the second section, the third section being perpendicular to the other two sections.

[0029] Thus, the pawls have optimized stiffness, which allows the pawls to withstand the pulling force that may be applied to the pawls due to, for example, the weight of an object or the pressure exerted by an occupant accidentally leaning on them when the concave element and the convex element are assembled together.

[0030] According to a preferred embodiment, the third section passes through the body, and the first section then extends on the first face of the body, and the second section extends along the second face of the body on the side opposite to the first face.

[0031] The third pin can be positioned on the second section and protrude from the second section. When the drive part drives the pin as it moves, the force applied to the pin thus enables the pawl to move, and in particular enables the first section to move away from the body in order to open these pawls.

[0032] The first section can form the hooking portion of the claw, which is configured to grip the convex element by extending behind the collar of the element. Due to the stiffness of the claw as a whole (which is made possible in particular by its C-shaped form), the first section does not deform, and the angles between the first section and the third section on the one hand and between the second section and the third section on the other hand do not change, even when the object to be fastened is heavy. Thus, the claw firmly holds the concave element on the convex element, thereby preventing any play that could generate noise and / or damage the object when the assembly is subjected to vibrations due to the running of the vehicle being supported.

[0033] The transmission part can include a pusher protruding from the body of the concave element, and the prestressed return member can be deformed by applying pressure on the pusher. Thus, it is easy for the user to actuate the pusher in order to open the claw to assemble the concave element with the convex element or, conversely, to disconnect the concave element from the convex element. When the user no longer applies pressure on the pusher, the transmission part returns to its initial position, and so does the prestressed return member.

[0034] The concave element can include a member for fixing to an object. This fixing member can be a recess for receiving a screw, a hook, a magnet, or any type of member enabling the concave element to be fastened temporarily or permanently to the object.

[0035] According to a second object, the invention relates to a concave element for a system according to the first object of the invention. The concave element can have the various features described above related to the concave element of the system according to the first object of the invention.

[0036] According to a third object, the invention relates to a motor vehicle comprising a system according to the first object of the invention. Description of the Drawings

[0048] Unless otherwise specified, in the drawings, the same elements have the same reference numerals.

[0049] As Figure 1 shown, a system 40 for fastening an object to a wall 52 according to an embodiment of the present invention includes a convex element 50 fastened to the wall 52 and a concave element 1 assembled with the convex element 50, the concave element 1 being capable of being rigidly connected to an object.

[0050] ​​​​​​​​​​​​​​The convex element 50 includes a head 54 that projects from the wall and includes a first collar 56 that extends over at least a portion of the periphery of the head. In this embodiment, the first collar 56 extends over the entire periphery of the head. In this embodiment, the convex element 50 includes a second collar 58 by means of which the convex element 50 bears against the wall 52. The convex element 50 that can be assembled with the concave element 1 described in the present invention is described in patent application FR2203604.

[0051] The concave element 1 includes a body 2 that is provided with a first claw 10a, a second claw 10b, and a third claw 10c. The claws 10a to 10c are connected by a prestressed return member ( Figure 1 (not shown) that allows the claws 10a to 10c to move relative to the body 2 and grip the collar 56 of the convex element 50 in order to assemble the concave element 1 with the convex element 50 by alternating between a closed position and an open position. In Figure 1 the figure, the concave element 1 is assembled with the convex element 50 and the claws 10a to 10c are in the closed position and inserted into the channel formed by the first collar 56 and the second collar 58.

[0052] Figure 2a and Figure 2b shows the concave element 1 without the prestressed return member. In this figure, the concave element 1 only includes the body 2 and the three claws 10a to 10c.

[0053] The body 2 includes a first face 2a or front face, and a second face 2b or rear face. In this embodiment, the body 2 is a substantially square hollow portion with chamfered corners. The rear face 2b is generally a hollow face that includes a recess 6 formed by two tabs 6a and 6b that enable the prestressed return member to be received. The front face 2a is a face that includes a relief that forms a ring around the main recess 8 so as to enable the convex element 50 to be received.

[0054] As Figure 3 shown, the three claws 10a to 10c (or 10) are identical and everything described for one claw also applies to the other two claws. The claw 10 is a C-shaped part that has a first section 12 and a second section 14 that are parallel to each other, and a third section 16 that connects the first section 12 and the second section 14. The third section 16 is substantially perpendicular to the section 12 and the section 14, which means that the third section 16 forms an angle of 90° ± 10° with the first section 12 and the second section 14.

[0055] As Figure 2a 、 Figure 2b and Figure 4bAs shown, the claws 10a to 10c are positioned on either side of the body 2 and are arranged such that the third section 16 passes through the body 2. Thus, the first section 12 is positioned against the front face 2a of the body to form the hooking portion of the claw 10a, which enables the grasping of the convex element 50. The second section 14 is positioned against the rear face 2b of the body and is used for the movement of the claw.

[0056] As can be seen in Figure 1 the C-shaped shape of the claw imparts optimized stability to it while allowing it to withstand tension. The first section 12 has an inner end 12a that is inserted between the first collar 56 and the second collar 58 of the convex element 50 (when assembled with the concave element). The outer end 12b is inserted into the ring of the body so as to form a continuous surface when the claws 10a to 10c are in the closed position.

[0057] The claw includes a pin 18 that is positioned on the second section 14 and projects towards the outside of the C. The pin 18 has the function of allowing the movement of the claw, as described below.

[0058] As Figure 4a shown, the concave element 1 includes a drive portion 20 that is positioned against the rear face 2b of the body 2. The drive portion 20 includes a first slot 22a and a second slot 22b into which the pin 18a of the first claw 10a and the pin 18b of the second claw 10b are inserted, and the pins 18a and 18b can slide along the first slot and the second slot. The drive portion 20 also includes an orifice 23 into which a third pin 18c is inserted. The interaction between the drive portion 20 and the pins 18 allows the claws 10a to 10c to move in order to assemble the concave element and the convex element, as described below.

[0059] The first slot 22a and the second slot 22b each include a first notch 25a and a second notch 25b at one of their ends, which enable the locking of the pins 18a and 18b without applying a force to compress the spring 30. When the sliding of the pins 18a and 18b is locked, the first claw 10a and the second claw 10b are locked in the closed position.

[0060] The first slot 22a and the second slot 22b extend in a divergent direction with respect to the movement axis of the drive portion 20, which enables the first claw 10a and the second claw 10b to move in a direction perpendicular to the movement direction of the drive portion 20 in order to allow the opening of these claws.

[0061] Additionally, the transmission part 20 includes a recess 24 that enables the reception of a prestressed return member 30, which is a spring in this embodiment. For this purpose, the transmission part includes a rod 26 that is inserted into the spring 30 and enables the compression of the spring 30 in the recess 6 of the body 2. The spring 30 is compressed during installation to ensure sufficient return force, enabling the claws 10a to 10c to close again after the concave element 1 and the convex element 50 are assembled.

[0062] In this embodiment, the transmission part 20 includes a pusher 28 that enables the transmission part 20 to translate against the body 2. The pusher 28 is placed at the top of the recess 24 and enables the compression of the spring when a user applies pressure to the spring 30, causing the transmission part to translate along the axis D1, which is also the compression axis of the spring 30. When the pressure on the pusher 28 is released, the return force allows the spring 30 to return to its initial position, causing the reverse translation of the transmission part 20, which then returns to its initial so-called rest position.

[0063] As Figure 5a and Figure 5b shown, the body 2 includes a cover 32 that enables the closing of the concave element 1 by clamping to the rear 2b of the body 2 with the aid of four clips 34. The cover enables the protection of the mechanism of the interaction between the transmission part 20, the spring 30, and the pins 18 of the claws 10.

[0064] The cover 32 includes a central orifice 36 around the tube 19, enabling the fixing of the concave element 1 to an object. In this embodiment, the tube 19 enables the reception of a screw for fastening the concave element 1 to any type of object. According to other embodiments, the concave element 1 can be fastened to an object by other types of fastening members.

[0065] The fastening system 40 operates simply and quickly by changing the position of the claws 10a to 10c between an open position and a closed position. The transition from one position to the other occurs by actuation of the pusher 28. The closed position (or rest position) corresponds to the initial position adopted when the concave element 1 is not fastened to the convex element 50, and also corresponds to the position adopted when the claws 10a to 10c close again around the collar 56 of the convex element 50 after the concave element 1 and the convex element 50 have been assembled. This closed position corresponds to the position adopted by the claws 10a to 10c when the spring 30 is not compressed or deformed. The open position is the position adopted by the claws 10a to 10c in order to be able to assemble the concave element 1 and the convex element 50. In this open position, the claws 10a to 10c move away from each other so that they can pass around the collar 56 of the convex element and then close again around the collar 56 by adopting the closed position. This position corresponds to the position adopted by the claws 10a to 10c when the spring 30 is compressed or deformed.

[0066] As Figure 4b shown, when the user acts on the spring 30 (e.g., by applying pressure on the pusher 28), the claws 10a to 10c can adopt the open position, thus driving the transmission part 20 to move and thus driving the claws 10a to 10c to move away from each other.

[0067] When the spring 30 is compressed, the first claw 10a and the second claw 10b perform movements along a first axis E1 and in two opposite senses, the axis E1 being perpendicular to the compression axis D1 of the spring 30. This movement is made possible due to the orientation of the slots 22a and 22b, which extend along diverging axes forming an angle of approximately 45° with the axis D1. Since the third pin 18c is inserted into the orifice 23 of the transmission part 20 and thus directly follows the movement of the transmission part 20, the third claw performs a movement along a second axis E2 parallel to the deformation axis of the prestressed return element.

[0068] As Figure 6a and Figure 6b shown, the fastening system according to the above-described embodiment can be used to fasten an object, such as a cup holder. The convex element 50 is positioned in the wall 52 of a motor vehicle, and the concave element 1 is fastened to the cup holder, for example. Thus, the cup holder 60 can be fastened to the wall 52 by positioning the concave element 1 facing the convex element 50 (as Figure 6a shown) and then pushing the concave element 1 against the convex element so as to force the claws 10 to open, or by applying pressure on the pusher 28 so as to open the claws. Once the concave element 1 and the convex element 50 are assembled together, the pressure can be released so that the claws 10a to 10c close again around the collar 56.

[0069] Thus, the cup holder 60 is firmly and securely fastened to the wall 52 and is accessible to the user without any risk of being thrown around in the event of a vehicle collision. However, the fastening of the cup holder 60 is reversible, and the cup holder can be easily detached from the wall by applying pressure on the pusher 28 to open the claws 10a to 10c and thus disconnect the concave element 1 and the convex element 50.
