Abstract

PROBLEM TO BE SOLVED: To enhance the effectiveness of the mounting works and stabilize the mounted condition. SOLUTION: A holding tool H is configured with a first engagement part F1 capable of being inserted into a mounting ring 9 of a torsion spring 8 and a second engagement part F2 capable of being engaged with a mounting hole 11 on the side with an instrument panel 1, and each engagement part is divided into two about the axis. In a position nearer the first engagement part F1, each element E generated by dividing is made rotatable by a hinge 10 between the spread condition and aligned condition. In the spread condition, a pair of pawls 17A constituting the first engagement part F1 are positioned opposingly, and there the mounting ring 9 can be inserted. Because the hinge 10 is arranged rotatable together in the connection part 16 with the two elements E, if the two elements are displaced so that the hinge 10 is inclined, the spacing of the pawls 17A can be narrowed, compared with the case where the hinge 10 is in the horizontal positioning, so that insertion into the ring 9 can be performed easily.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holder.

[0002]

2. Description of the Related Art Conventionally, an openable and closable cover is attached to a glove box of an automobile (see FIG. 1 for reference). The cover 3 is held in a closed state by a lock mechanism. However, when the lock device is released and the cover 3 is slightly opened, the cover 3 is automatically and slowly moved to the fully open position by a spring force. It can be migrated with. Conventionally, the spring 8 performing such an operation has been attached using rivets or screws.

[0003]

However, when the rivet is driven or the screw is tightened, the mounting operation is cumbersome and takes much time. Further, it is not inconceivable that the end of the spring is simply hooked on the target member, but it is easy to come off and the reliability of the attachment is low. As a countermeasure, a method of attaching using a resin clip can be considered, but even in this case, it is desired that the spring can be easily attached to the clip and that the attachment state is stable.

The present invention has been devised in view of the above-mentioned conventional problems, and an object of the present invention is to provide a holder which is excellent in mounting workability and can realize a stable mounting state. is there.

[0005]

According to a first aspect of the present invention, there is provided a holder for fixing a member having a through hole to a fixing member having a mounting hole. A first locking portion inserted into the through hole and locked to the mounted member; and a first locking portion disposed continuously from the first locking portion and inserted into the mounting hole and locked to the fixing member. And the entire holding tool is divided along the axial direction and divided into a pair of elements, so that the first locking portion becomes two claw pieces and The engaging portion is divided into two leg pieces, respectively, and both elements are connected by hinge pieces at the tip side of the claw pieces, so that the deployed state of the element through which the both claw pieces can be inserted into the through hole is provided. And the two claw pieces constitute a first locking portion while the through-hole At the same time, the two leg pieces constitute a second locking portion, and are rotatable between an alignment state of an element that can be inserted into the mounting hole in a retaining state, and When both elements are in the unfolded state, they are formed to have a width such that a predetermined distance is maintained between the claw pieces, and both end edges connected to both elements are turned together as hinge portions. It is characterized in that it constitutes a pivot point.

According to a second aspect of the present invention, in the first aspect of the present invention, the interference between the hinge piece and the claw piece during the transition from the deployed state to the aligned state is avoided near the pivot of the hinge piece. Is formed with a notch. The invention according to claim 3 is the device according to claim 1 or 2, wherein the position of the two elements near the hinge is cut off to avoid interference between the elements during the transition from the deployed state to the aligned state. It is characterized in that a surface is formed.

[0007]

According to the first aspect of the present invention, when the holder is to be mounted on the member to be mounted, first, both elements are in a deployed state. In this deployed state, the claw piece can be inserted into the through-hole of the attached member, but since the hinge piece has both ends as hinge parts and serves as a rotation fulcrum, if these pieces are rotated around these, Therefore, it is possible to make the tips of the both claw pieces approach each other. Therefore, the initial operation of inserting the attached member into the through hole is simplified. Also. Even if you move the hinge piece so that it is inclined,
The horizontal distance between the claw pieces can be made smaller than the same distance when the hinge pieces are in a deployed state in which the hinge pieces are horizontal. With this configuration, the turning radius of the element during the transition to the alignment state can be reduced, and the work of attaching the element to the attached member becomes smooth. In this way, by rotating both elements to the aligned state with the hinge pieces, the two claw pieces constitute the first locking portion and are locked around the mounting hole, so that the entire holder is attached to the member to be mounted. Is done. At the same time, since both leg pieces constitute the second locking portion, it can be fixed to the fixing member via the mounting hole. Thus, the attachment of the attached member to the fixing member is completed.

According to the second or third aspect of the present invention, by avoiding interference during the transition of the two elements from the deployed state to the aligned state, the rotation range of the two elements can be made as small as possible. Become like

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 is a cross-sectional view showing an outline of an opening / closing structure of a cover of a glove box of an automobile.
In the figure, reference numeral 1 denotes an instrument panel (hereinafter, referred to as an instrument panel 1), and a storage room 2 which is open to the front side is defined at a position facing the passenger seat. A cover 3 which can be opened and closed in a flip-up manner is attached to the front surface of the accommodation room 2 by a hinge 4. A lock means (not shown) is attached to the cover 3 so that the closed state of the cover 3 can be locked.

Further, an escape hole 5 is opened in the back wall 2A of the accommodation room 2, and an auxiliary arm 6 for urging the cover 3 to the fully open position is inserted therethrough. The base of the auxiliary arm 6 is guided to the back side of the accommodation room 2, and is attached to the instrument panel 1 via a pin 7. The auxiliary arm 6 extends to a position where it comes into contact with the inner surface of the cover 3 through the escape hole 5, and its distal end extends while the cover 3 opens and closes.
To be in sliding contact with the inner surface of the One end of a torsion spring 8 is hooked at a position near a pivot (pin 7) of the auxiliary arm 6. The torsion spring 8 plays a role of urging the auxiliary arm 6 to open the cover 3. The other end of the torsion spring 8
A mounting ring 9 (corresponding to a through hole of the present invention) which is bent in a circular shape is formed, and the mounting ring 9 is rotatably mounted on a wall surface in the instrument panel 1 by a holding tool H described below, whereby torsion is obtained. The entire spring 8 is mounted.

The holder H is integrally formed of a synthetic resin material, and as a whole, as shown in FIG. 9, a first locking portion F1 for locking to a mounting ring 9 of a torsion spring 8,
It comprises a first locking portion F1 and a second locking portion F2 which is continuous with the lower side and is locked to the wall surface of the instrument panel 1. Further, the holder H is divided along the axial direction, and includes a pair of elements E having a symmetrical shape. Both are rotatable between a deployed state and an aligned state by a hinge piece 10 described later, so that the two elements E are aligned to form the above-mentioned locking portions F1 and F2. .

First, the second locking portion F2 will be described. The second locking portion F2 has a contact plate 12 formed in a disk shape having a diameter larger than the mounting hole 11 penetrating through the wall surface of the instrument panel 1. And
Below the contact plate 12, a leg 13 composed of a pair of leg pieces 13A is formed. The tip of the leg 13 is formed with a tapered surface 13B such that the outer peripheral surface is tapered in order to smoothly insert the leg 13 into the mounting hole 11. Between the tapered surface 13B and the contact plate 12, there is a shaft 13C having a cylindrical shape. In both the shafts 13C, locking elements for locking the holes E of the mounting holes 11 are provided on both elements E. 14 are provided. The locking pieces 14 are provided in a cantilever manner so as to project obliquely outward from the lower edge of the window hole 15 opened to the shaft portion 13C, so that the locking pieces 14 can be bent and deformed inside the shaft portion 13C. Accordingly, the shaft portion 13C can be inserted into the mounting hole 11. A locking step 14 </ b> A is formed at the tip of the locking piece 14, and can be locked to the hole edge of the mounting hole 11.

Next, a description will be given of the first locking portion F1. A connecting portion 16 is provided at the center of the contact plate 12, and a holding portion constituted by a pair of claw pieces 17A is provided at the upper end thereof. A plate 17 is arranged coaxially. However,
The gap between the holding plate 17 and the contact plate 12 is set slightly larger than the thickness of the mounting ring 9 of the torsion spring 8. The holding plate 17 is formed to project slightly larger than the contact plate 12.

The two claw pieces 17A are connected at their roots by hinge pieces 10, so that when both elements E are deployed, the two claw pieces 17A face each other. The mounting ring 9 of the torsion spring 8 is fitted between the two pawl pieces 17A and the abutting plate 12 (hereinbelow, referred to as the insertion groove 18) which are opposed to each other. In addition, the tip edge of the nail piece 17A is formed into a cut-off shape with an inclined surface 17B over the entire width.

An oblique cut-off surface 19 is formed at the boundary between the claw piece 17A and the connecting portion 16, so that interference between the elements E can be minimized in the process of shifting the two elements E from the deployed state to the aligned state. Try to avoid it. Further, the hinge piece 10 is provided on the cut surface 1.
9 are provided so as to bridge the upper edges of the portions where the 9 is provided. The hinge piece 10 is formed to have the same width as the two claw pieces 17A, and the upper surfaces at both ends are removed along the entire width to form a relief portion 10A. In this way, the escape portion 10A is provided at the connection portion 16 minutes with the nail piece 17A.
, Both elements E constitute a hinge portion at both ends of the hinge piece 10 and can be rotated in each of them, and interference between the hinge piece 10 and the claw piece 17A is avoided as much as possible. .

Next, the operation and effect of this embodiment configured as described above will be specifically described. First, both elements E are deployed and the two claw pieces 17A are opposed to each other.
When the torsion spring 8 is inserted into the attachment ring 9, the hinge pieces 10 are turned around the ends of the hinge piece 10 so that the claw pieces 17A approach each other. By doing so, the mounting ring 9 of the torsion spring 8 can be easily inserted into both the insertion grooves 18. Of course, in this case, attachment to the attachment ring 9 can be performed in the following manner. That is, as shown in FIG. 5, both hinge pieces 10 are
Is shifted in the height direction. As a result, the horizontal distance between the two insertion grooves 18 is reduced while the insertion grooves 18 are substantially parallel to each other.
Thereby, the mounting ring 9 of the torsion spring 8 can be inserted straight to the bottom of both insertion grooves 18 in a natural state. That is, when the two elements E are shifted in the height direction as shown in FIG. 5, the above-mentioned case is more pronounced than the horizontal distance between the two insertion grooves 18 when the hinge piece 10 is horizontal as shown in FIG. 4. The distance can be shortened. Therefore, insertion into the mounting ring 9 can be easily performed.

Thereafter, as shown in FIG.
While crushing one of the relief portions 10A (the one on the left side in the figure), the element E on the right side in the figure is rotated about the end on the crushed side. By doing so, the element E on the right side in the figure can be rotated with a minimum radius, so that the mounting ring 9 can be rotated without incurring the expansion. When the element E on the right side in the drawing is in an upright posture along the axis, the hinge piece 10 is rotated around the opposite end (the right end shown in FIG. 7). . Also at this time, the interference between the two elements E is avoided by the cut-off surface 19, so that the element E on the left side in the figure can be rotated with the minimum radius. Accordingly, the mounting ring 9 does not expand during this time.

Then, when the elements E come into contact with each other as shown in FIG. 8, the two elements E are rubbed together so that the heights thereof are made equal to each other, so that both elements are brought into an aligned state. Thus, the torsion spring 8 is wound around the connection portion 16 and is held between the contact plate 12 and the holding plate 17.

Thereafter, the leg portion 13 composed of the leg piece 13A in the aligned state is pushed into the mounting hole 11 on the instrument panel 1 side. This allows both locking pieces 14 to bend and deform inwardly, thereby allowing insertion into the mounting hole 11 and allowing the contact plate 12
At the time when the abutment comes into contact with the surface on the instrument panel 1 side, the locking pieces 14 are elastically restored, and the locking step 14A is locked on the edge of the mounting hole 11 (state in FIG. 9). As a result, the mounting of the torsion spring 8 is completed.

As described above, according to the present embodiment, by setting the rotation fulcrum at both ends of the hinge piece 10, the two elements E are moved so that the insertion groove 18 can move in parallel while narrowing the interval between them. Can be displaced. Therefore, the operation from the initial insertion of the torsion spring 8 to the mounting ring 9 to the completion thereof can be easily performed. Also, by setting the relief portion 10A on the hinge piece 10 and the cut-off surface 19 on the connection portion 16, it is possible to avoid interference at the time of the rotation operation of the two elements E, and to shift from the deployed state to the aligned state. Operation can be performed smoothly. Thereby, the diameter of the mounting ring 9 is set to the claw piece 17A.
Since the element E is held in a substantially natural diameter from the time of insertion into the element until the alignment of the two elements E is completed, there is no excessive expansion deformation. Since they are closely fitted, no rattling occurs. Furthermore, since the holding tool H is formed in an unfolded state as shown in FIG. 4, it can be formed only by a mold that is split in the vertical direction in the figure. In other words, if you do not split in this way,
Although a slide core is required to form the locking piece 14 and the mold structure is complicated, this is not necessary in the present embodiment, and the mold structure may be simple. When a slide core is used, it is not necessary to cut out the tapered surface 13B serving as an insertion port, so that the tapered surface 13B can be formed larger than in the past, so that the insertability of the holder H into the mounting hole 11 is improved. Can be done.

The present invention can be variously modified,
The following modifications are also included in the technical scope of the present invention. In this embodiment, the torsion spring 8 is used as an attached member.
However, the present invention is not limited to this, and it is also possible to apply the present invention to various objects having a through hole (for example, a plate). Also,
Various shapes are also conceivable for the second locking portion F2. For example, it is also possible to set an anchor shape or the like and to divide the shape into two.
