Description

Title of the invention: Vehicle trunk fixing hook for car.

[0001] The technical field relates to fastening hooks for car trunks, car trunks including such a fastening hook, as well as motor vehicles.

[0002] Automobile manufacturers take great care in developing their vehicles to offer their customers vehicles with impeccable build quality. Build quality is reflected, first and foremost, in the quality of the assembly and materials used in the vehicle. However, the quality perceived by customers is also influenced by the quality of the accessories supplied with the vehicle.

[0003] In this context, motor vehicles are frequently supplied with fastening devices for securing luggage in the vehicle's trunk. These fastening devices are designed to be inserted into an anchor hole and are equipped with a ring to which luggage and / or nets can be attached. These fastening devices are obviously very practical but have the disadvantage of significant play when secured in their anchor hole. This play is sometimes perceived as a sign of poor device stability, so users may interpret this play as a quality defect.

[0004] Thus, there is a need for a solution to improve the fixing of the fixing devices by eliminating the play in movement that can be perceived when handling the devices.

[0005] The present invention aims to overcome the problems described above. In this technical context, one objective of the present invention is to provide a fastening hook exhibiting reduced play when inserted into a fastening hole in the floor of a trunk.

[0006] To this end, the present invention relates to a fastening hook designed to allow the securing of luggage in the trunk of a motor vehicle, the hook comprising an anchoring portion designed to be inserted into an anchoring hole provided in a floor, the anchoring portion comprising retractable anchoring means designed to deploy and anchor the hook to the floor when the anchoring portion is inserted into the hole, the anchoring means being controlled by a hook control, mounted to rotate between an unlocked position, in which the anchoring means are retractable to allow the passage of the anchoring portion into the hole, and a locked position, in which the Anchoring means are deployed to allow the hook to be anchored to the floor, the hook further comprising elastic return means designed to bear against the floor when the hook is anchored to the floor, the control and the elastic return means being designed to block the compression of at least a part of the elastic return means in a compressed position when the control is in the locked position.

[0007] The invention also relates to a motor vehicle trunk comprising a floor having at least one anchoring hole, the trunk further comprising at least one fixing hook according to the invention, the anchoring part of each hook being dimensioned to be inserted into an anchoring hole, when the control is in the unlocked position, and to allow the hook to be anchored to the floor when the control is in the locked position.

[0008] The invention finally relates to a motor vehicle having at least one trunk according to the invention.

[0009] Thus, the hook according to the invention allows for the attachment of luggage and / or a net designed to secure luggage. The anchoring portion allows the hook to be engaged and secured in the anchoring hole. The elastic return means are designed to bear against the floor when the hook is anchored to the floor, thereby reducing the hook's movement within the hole. When the vehicle user uses the fastening hook, by flipping the control, they block the compression of a portion of the elastic return means, thus limiting the hook's movement towards the floor. Therefore, the elastic return means and the control, working together when the control is in the locked position, introduce at least a partial blockage of the elastic return means, limiting the movement of the hook anchored in the hole.The hook according to the invention therefore improves the quality perceived by users compared to conventional fastening devices.

[0010] According to one embodiment of the invention, the elastic return means comprise at least one hairpin spring including at least one elastic wire forming at least two strands, one of the strands having a protrusion shaped to bear against the other strand when the control is in the locked position. By bearing against each other, the two strands limit the compression possibilities of the elastic return means.

[0011] According to one possibility, the protrusion is provided at one end of an elastic wire.

[0012] In one embodiment of the fastening hook, the control is mounted to rotate about an axis of rotation, the axis of rotation forming a cam designed to bear against the elastic return means at least when the control is in the locked position.

[0013] Advantageously, the cam is designed to compress the return means elastic against the floor, when the control is moved from the unlocked position to the locked position and when the anchoring part is inserted into the hole in the floor.

[0014] According to one possibility, the control forms a mooring ring.

[0015] In one embodiment, the control rotates a quarter turn between the unlocked position and the locked position.

[0016] The invention will be better understood upon reading the following detailed description, given solely by way of non-limiting example and made with reference to the accompanying drawings in which:

[0017] [Fig-1] [Fig.1] represents a partial view of a chest according to the invention showing works a first embodiment of a fixing hook inserted into an anchoring hole in a trunk floor;

[0018] [Fig.2] [Fig.2] represents a partial view of a chest according to the invention showing works a second embodiment of a fixing hook inserted into an anchoring hole in a floor of the trunk;

[0019] In these figures, the same references are used to designate the same elements.

[0020] A hook la, 1b for fixing according to the invention, illustrated in the figures, is designed to allow the fixing of luggage in a trunk 2 of a motor vehicle.

[0021] The hook 1a, 1b includes an anchoring portion 3 designed to be inserted into a fixing hole 4 provided in a floor 5. As illustrated in the figures, the anchoring portion 3 has, for example, a shape inscribed in a cylinder with a circular base. The anchoring portion 3 is dimensioned to be inserted into the hole 4.

[0022] The anchoring part 3 includes retractable anchoring means 6, designed to deploy and anchor the hook la, 1b to the floor 5 when the anchoring part 3 is inserted into the orifice 4.

[0023] The anchoring means 6 are controlled by a control 7a, 7b of the hook la, 1b, mounted movably to rotate between an unlocked position (illustrated in [Fig.1]), in which the anchoring means 6 are retractable to allow passage of the anchoring part 3 in the orifice 4, and a locking position (illustrated in [Fig.2]), in which the anchoring means 6 are deployed to allow anchoring of the hook la, 1b on the floor 5. Advantageously the hook la, 1b includes a mechanism, not visible in the figures, which locks the anchoring means 6 in the deployed position when the control 7a, 7b is in the locking position.

[0024] As illustrated in the figures, the control 7a, 7b forms a mooring ring 8. The mooring ring 8 allows luggage to be secured using, for example, a strap passed through the mooring ring 8. In the example illustrated in the figures, the control 7a, 7b rotates a quarter turn between the unlocked position, illustrated on the [Fig.1], and the locking position, illustrated in the [Fig.2].

[0025] In the examples illustrated in the figures, the anchoring means 6 have two movable lugs 9. When the anchoring means 6 are in the retracted position, the lugs 9 are at least partially retracted or retractable into the anchoring portion 3. When the anchoring means 6 are in the deployed position, the lugs 9 protrude from the anchoring portion 3, so as to bear against the floor 5 to anchor the hook 1a, 1b to the floor 5, preventing the anchoring portion 3 from being withdrawn from the opening 4.

[0026] The hook 1a, 1b further includes elastic return means 10 designed to bear against the floor 5 when the hook 1a, 1b is anchored to the floor 5. In the examples shown in the figures, the elastic return means 10 comprise at least one hairpin spring 11 including at least one elastic wire 12 forming at least two strands 13a, 13b. One 13a of the strands 13a, 13b has a protrusion 14 shaped to bear against the other strand 13b when the control 7a, 7b is in the locked position. In the example shown in the figures, the protrusion 14 is provided at one end 15 of the elastic wire 12. In this case, the protrusion is formed by a bend in the end 15.

[0027] The control 7a, 7b and the elastic return means 10 are designed to prevent the compression of at least a portion of the elastic return means 10 in a compressed position when the control 7a, 7b is in the locked position. Thus, in the example illustrated in the figures, the protrusion 14 comes into contact with the strand 13b. When the two strands 13a, 13b are pressed against each other, the compression of the hairpin spring 11 is limited, or even prevented.

[0028] In the embodiments illustrated in the figures, the anchoring means 6 are designed to compress the elastic return means 10 against the floor 5, when the control is moved from the unlocked position to the locked position and when the anchoring part 3 is inserted into the orifice 4 of the floor 5.

[0029] In the embodiment illustrated in [Fig. 2] of the hook 1b, the control 7b is mounted to rotate about an axis A. The axis A forms a cam 16 designed to bear against the elastic return means 10 at least when the control 7b is in the locked position. The cam 16 forms an additional piece of material on the axis A which, in cross-section, has an elliptical or ovoid shape.

[0030] Advantageously still, the cam 16 of the anchoring means 6 is designed to compress the elastic return means 10 against the floor 5, when the control 7b is moved from the unlocked position to the locked position and when the anchoring part 3 is inserted into the orifice 4 of the floor 5.

[0031] Thus, the hook la, 1b allows for the attachment of luggage and / or a net intended to retain luggage. The anchoring part 3 allows the hook la, 1b to be engaged and secured in the anchoring hole 4. The elastic return means 10 are designed to bear against the floor 5 when the hook la, 1b is anchored to the floor 5, and to reduce the travel of the hook la, 1b in the hole 4. By flipping the control 7a, 7b, the user blocks the compression of part of the elastic return means 10, thus limiting the movement of the hook la, 1b towards the floor 5. Therefore, the elastic return means 10 and the control 7a, 7b, when the control 7a, 7b is in the locked position, introduce at least a partial blockage of the elastic return means 10, limiting the travel of the hook la, 1b anchored in the hole 4.

[0032] The invention is not limited to the embodiment of the fixing hook described above, only by way of example, but other embodiments can be designed by a person skilled in the art without departing from the scope and extent of the present invention.
