BACKGROUND

1. Field of the Invention

The present invention relates to a fixture for a vehicle, and more particularly, to a fixture for a vehicle, in which a plurality of retaining arms substantially serving as stoppers are arranged in the form of a pyramid so that an external force transmitted from an outer side to, for example, an indoor handle is equally dispersed to each retaining arm, and the fixture is prevented from being escaped or separated from a coupling hole formed in a body panel, and thus noise is reduced, and a safety accident generated when the indoor handle falls into an interior of the vehicle is prevented.

2. Discussion of Related Art

Generally, various construction elements are assembled in a vehicle using a fixture. For example, the construction elements include a room lamp, a head lamp, and an indoor auxiliary handle. At this time, the used fixture may be separately manufactured and used according to each construction element. However, in an aspect of productivity and cost reduction, one kind of fixture is generally developed and applied to all places which are required to be coupled in a clip manner. Patent documents 1 to 3 show examples in which a module clip capable of being used in another construction element is used to fix a headliner.

Patent documents 1 provides an indoor handle fixture for a headliner module of a vehicle, in which a base 110 assembled between a body panel 10 and a headliner 20 is provided at a base end, and a hook 120 integrally bent from the base 110 to be inserted and coupled into a coupling hole 11 of the body panel 10 is formed at a fore-end, wherein the hook 120 includes two pairs of supporting arms 121 having supporting portions 121a bent from both sides of the base 110 to be inclined upward in directions facing each other and flanges 121b bent downward from upper ends of the supporting portions 121a, one pair of retaining arms 123 formed between the two pairs of supporting arms 121 to be bent from centers of the flanges 121b and to be inclined downward in directions far away from each other, retaining portions 124 bent from lower ends of the retaining arms 123 to be inclined downward in directions facing each other, retaining jaws 125 bent downward from lower ends of the retaining portions 124 to be caught by a circumferential surface 11a of the coupling hole 11 of the body panel 10, and insertion guide beads 126 formed at centers of the retaining arms 123 to extend from upper ends to lower ends and to protrude in directions far away from each other.

Patent document 2 relates to an indoor handle fixture for a headliner module of a vehicle, which has a simple manufacturing process and a low manufacturing cost, and is configured to restrict generation of noise when being installed and used in the vehicle. In the indoor handle fixture for the headliner module of the vehicle, in which a base 110 assembled between a body panel 10 and a headliner 20 is provided at a base end, and a hook 120 integrally bent from the base 110 to be inserted and coupled into a coupling hole 11 of the body panel 10 is formed at a fore-end, the hook 120 includes supporting arms 121a bent from both sides of the base 110 to be inclined upward in directions facing each other and flanges 121b formed to extend from upper ends of the supporting arms 121a to both sides of the supporting arms 121a and to be bent downward, two pairs of retaining arms 122 bent from both sides of the flanges 121b to be inclined downward in directions far away from each other, retaining portions 123 bent from lower ends of the retaining arms 122 to be inclined downward in directions facing each other, retaining jaws 124 bent downward from lower ends of the retaining portions 123 to be caught by a circumferential surface 11a of the coupling hole 11 of the body panel 10, and at least one noise preventing protrusion 125 formed to restrict generation of noise due to mutual contact of the flanges 121b configured to protrude from opposed surfaces of the flanges 121b to face each other.

Patent document 3 relates to an indoor handle fixture for a headliner module of a vehicle, including a base 110 assembled between a body panel 10 and a headliner 20, and a hook 120 bent from the base 110 to be inserted and coupled into a coupling hole 11 of the body panel 10, wherein the hook 120 includes one pair of supporting arms 121 generally formed in a “T” shape and having flanges 121a bent from upper ends thereof to face each other and to be in contact with each other, retaining arms 122 formed to gradually extend outward from upper horizontal sides of the supporting arms 121 toward a bottom and bent inward at an end thereof to form hooking portions 122a, cut-away portions 123 formed at portions, in which transverse and longitudinal portions of each supporting arm 121 are met, to be gradually directed upward toward the longitudinal portions, and shoulders 124 formed to extend from outer frames of connection portions between the retaining arms 122 and the flanges 121a, wherein at least one pair of movement preventing protrusions 112 are integrally formed at portions of the base 110 cut in the form of a “C” shape to face each other toward the flanges 121a, and the pair of movement preventing protrusions 112 are gradually bent inward toward a top thereof, and at least one nose preventing protrusion 121b is further provided at one of both opposed surfaces of the one pair of flanges 121a to be in point-contact.

However, these conventional fixtures are generally manufactured in the form of a clip, and the clip-shaped fixture has the following problems.

(1) The conventional fixtures (clip modules) have a structure which is not moved once they are fixed. For example, in case of a room lamp, a head lamp, and a headliner, since they are not moved and an external force is hardly applied to them, there is no problem. However, when the indoor handle which is grasped by a passenger and to which an external force is applied is fixed, there are some problems as follows.

(2) Since the fixture is manufactured so the retaining arms substantially serving as hooks are located to face each other and to be symmetrical vertically or horizontally, the external force applied to the indoor handle may not be uniformly dispersed to the retaining arms.

(3) That is, when the external force is applied in a direction in which an auxiliary handle is grasped and pulled downward, the external force is uniformly applied to the conventional fixture and thus the retaining arms. However, when the auxiliary handle is twisted or grasped to be inclined to one side, the conventional fixture is twisted by a force generated at this time, and thus the retaining arms are also twisted.

(4) In the retaining arms twisted as described above, the force is applied to one of the retaining arms or to one side, and thus the twisted retaining arms may be separated from or may escape from a coupling hole.

(5) This is caused by a structure in which the force applied to the indoor handle may not be dispersed to each retaining arm, even when being applied in any directions, i.e., a structure in which the retaining arms face each other.

(6) Meanwhile, the conventional fixture which is vulnerable to the twisting may be separated from or may escape from the coupling hole, when the indoor handle is used.

(7) When the fixture is separated, the fixture may bump against other construction elements and may generate noise, and thus the separation of the fixture may act as a factor which deteriorates riding comfort.

(8) The indoor handle is generally fixed by two fixtures, and when all of the fixtures are separated from the coupling hole, the indoor handle may fall into an interior of the vehicle, and thus a safety accident may occur.

DETAILED DESCRIPTION OF THE INVENTION

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the terms used in the specification and the appended claims should not be construed as limited to general and dictionary meanings, but interpreted based on the meanings and concepts corresponding to technical aspects of the present invention on the basis of the principle that the inventor is allowed to define terms appropriately for the best explanation.

Therefore, the description proposed herein is just a preferable example for the purpose of illustrations only, not intended to limit the scope of the invention, so it should be understood that other equivalents and modifications could be made thereto without departing from the spirit and scope of the invention.

(Construction)

As illustrated in FIGS. 4 to 7, a fixture for a vehicle according to the present invention includes a base 100 formed in a circular shape to have a fastening hole 110 formed in a center thereof, and a plurality of guides 200 and retaining arms 300 alternately formed at edge portions of the base 100.

In particular, the present invention is used to fix a headliner, a head lamp, or an indoor handle by inserting the retaining arms 300 into a coupling hole H formed in a body panel P, and the retaining arms 300 are arranged to form a triangular pyramid. Therefore, even though a force is applied in any directions of the fixture, the retaining arms 300 configured to perform coupling action disperse and absorb the force, and thus prevent the fixture of the present invention from being separated from or escaping from the coupling hole.

The detailed description of such a structure is as follows. Here, the fixture of the present invention is used to fix the headliner, the room lamp, the head lamp, the indoor handle, or the like. In the specification, it is assumed that the fixture is installed at the indoor handle to which an external force is most frequently applied in an installed state, and thus which may be separated or disassembled. In FIG. 6, an unexplained reference numeral 20 is the headliner, 41 is a fixture plate installed between the body panel 10 and the headliner 20, 40 is the indoor handle, and 42 is a fastening means, such as a screw, onto which the indoor handle 40, the headliner 20, and the fixture plate 41 are inserted and which is fastened into the fastening hole 110.

As illustrated in FIGS. 6 and 7, the base 100 has the fastening hole 110 formed in a center thereof. The fastening hole 110 is used to fasten the fastening means (not shown) such as the screw used when the indoor handle is fastened. In the preferred embodiment of the present invention, FIG. 7 illustrates an example in which the base 100 is formed in a regular hexagonal shape. This is to sequentially and alternately form the guides 200 and the retaining arms 300 at each side. However, the base 100 is not limited thereto, and may be formed in an n-polygonal shape (“n” is an even number equal to or larger than 6). In this case, the guides 200 are formed at odd-numbered sides, and the retaining arms 300 are formed at even-numbered sides.

As illustrated in FIGS. 4 to 7, the guides 200 are formed to be in contact with an inner surface of the coupling hole H. At this time, the guides 200 serve to guide and then support the fixture of the present invention, when the fixture is inserted into the coupling hole H.

As illustrated in FIG. 7, three guides 200 are formed at the base 100 to be respectively in close contact with three of six inner surfaces of the coupling hole H formed in the regular hexagonal shape. At this time, each guide 200 is formed to be alternately in close contact with adjacent one of the inner surfaces. Therefore, since the three guides 200 are formed on an imaginary circle based on the fastening hole 110 to be spaced at regular intervals from each other and thus to be supported by three points, the fixture of the present invention may be stably inserted and supported into the coupling hole H.

In the preferred embodiment of the preset invention, the three guides 200 are provided, but not limited thereto. Three or more guides 200 may be provided. This is caused by that the base 100 is formed in the regular hexagonal shape. When the base is formed in a regular n-polygonal shape (“n” is an even number equal to or larger than 6), the actual number of the guides 200 is n/2.

Further, in the preferred embodiment of the present invention, as illustrated in FIG. 7, the guides 200 are preferably formed so that a portion thereof which is horizontal with a surface of the base 100, while being in contact with the inner surface of the coupling hole H, protrudes upward and is in close contact with the inner surface of the coupling hole H. This is to allow a flat portion defined by the guide 200 and the base 100 to be in close contact with the body panel (not shown), thereby increasing a contact area therebetween and thus being stably supported.

As illustrated in FIGS. 4 to 7, each retaining arm 300 is formed between the adjacent two guides 200. In particular, longitudinally middle portions of the retaining arms 300 are folded to be in contact with each other above the fastening hole 110, as illustrated in FIGS. 4 to 6.

As illustrated in FIG. 6, the retaining arms 300 are formed to be spread outward, and a hooking portion 310 is formed at each end of thereof. As illustrated in FIG. 7, when the fixture of the present invention is inserted into the coupling hole H, the hooking portion 310 is caught by an inner edge portion of a side forming the coupling hole H.

In the preferred embodiment of the present invention, a portion of each retaining arm 300, which is folded outward based on the longitudinally middle portion thereof, is preferably formed to be spread to an outer side of the fixture of the present invention, such that the fixture is generally formed in a pyramid shape, as illustrated in FIGS. 4 and 7. Therefore, a pyramidal portion allows an easy assembling operation of the fixture, when the fixture is inserted into the coupling hole H, and also since the plurality of retaining arms 300 are arranged on the imaginary circle to be spaced at regular intervals, a force applied to the fixture is dispersed and absorbed by the retaining arms 300 uniformly supported by the three points, even when the force is applied in any directions, and thus the fixture is prevented from escaping from or being separated from the coupling hole.

Further, in the preferred embodiment of the present invention, the retaining arms 300 may have at least one reinforcing bead 320 formed at one surface thereof in a lengthwise direction, and thus may reinforce a structural strength. The drawings illustrate an example in which the reinforcing bead 320 is formed at an outward protruding portion of the longitudinally folded middle portion of the retaining arm 300 to be recessed toward an inner side of the fixture.

Meanwhile, the fixture of the present invention may be manufactured by a press working process of a metal plate, and thus may have a simple structure to be easily manufactured and used, and also may be massively manufactured.

To this end, the fixture may be manufactured by cutting the metal plate by a length necessary to form each guide 200 and retaining arm 300 based on the circular base 100 and folding the guide 200 and the retaining arm 300 in the above-mentioned shape.

In the present invention as described above, since the plurality of retaining arms serving as hooks are formed in the pyramid shape to be arranged on the imaginary circle, when a force is applied to the fixture in a direction which is twisted or inclined to one side, the retaining arms serving as hooks at predetermined positions of the inner surface of the coupling hole disperse and absorb the force, and thus stably support the fixture to be prevented from escaping from or being separated from the coupling hole.

The fixture for the vehicle according to the present invention has the following effects.

(1) In the case of the indoor handle to which the external force is applied by a passenger, as well as the headliner, the room lamp, and the head lamp to which the external force is hardly applied, once they are fixed, the external force can be effectively dispersed.

(2) That is, since the three retaining arms serving as the hooks are arranged on the imaginary circle based on the center of the base to be spaced at regular intervals, even when the force is applied to the fixture, the force can be dispersed and absorbed through the retaining arms configured to support the fixture in all directions. Therefore, the fixture of the present invention can be prevented from easily escaping from or being separated from the coupling hole.

(3) Since the fixture is prevented from easily escaping from or being separated from the coupling hole, the noise generated when the fixture is separated from the coupling hole and then collides with other construction elements can be prevented, and the riding comfort can be increased, and a safety accident generated so that the indoor handle falls into an interior of the vehicle and hurts the passenger can be prevented.

(4) In particular, according to the present invention, since the retaining arm is formed in the pyramid shape, even when the fixture is twisted or inclined to one side by a force, the retaining arms facing each other in all directions can stably disperse and absorb the force, and thus the separation or escaping prevention effect of the fixture can be further improved.

(5) Further, according to the present invention, since the three retaining arms are formed in the pyramid shape, the fixture can be easily inserted and installed into the coupling hole, and also since the retaining arms can uniformly apply the force to the whole coupling hole, the fixture can be supported so as not to escape from or be separated from the coupling hole, even when the force is applied in any directions of the fixture.

It will be apparent to those skilled in the art that various modifications can be made to the above-described exemplary embodiments of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention covers all such modifications provided they come within the scope of the appended claims and their equivalents.
