Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting structure for a sliding body such as a sliding door of a console box mounted on an automobile or an ashtray.

[0002]

2. Description of the Related Art A console box door is of a type that opens by rotating, or a type that opens by sliding as shown in FIG. In the illustrated case, doors 59 are provided in upper and lower two stages, and the boxes are opened and closed separately. In the case of such a slide type, the support structure of the door 59 is as shown below. A pair of left and right rails 57 are attached to both side edges of the box body in the console box along the length direction (front-back direction). Both rails 57 have upper and lower two-tiered channel grooves 58.
A support member 62 corresponding to both doors 59 is slidably fitted therein. Support member 62 is a double door 5
It is attached by being fitted in the notch recessed part 60 formed in each side edge of 9. Spring members 70 are housed in both support members 62,
The pressure contact piece 67 formed on the upper portion of the support member 62 is pressed against the inner surface of the rail 57 to apply a predetermined operation load.

Further, the door of the console box can be opened by rotating, or can be opened by sliding as shown in FIG. In order to obtain smooth operability when sliding on the guide rail, the spring is stored in a resin box (injection molded product), and sliding with the rail is made of resin (polyacetal, polyethylene, polybutylene terephthalate, etc.). It is common to have a contact structure. When the door has a sliding structure, the operating force when manually opening and closing depends on the sliding resistance (friction force) between the rail and the resin box, which is largely due to the force of the built-in spring pushing up the resin box. Is. Therefore, in order to adjust the operating force up and down, it is necessary to increase the thickness of the leaf spring or change the shape. Since the leaf spring is manufactured by press molding as shown in FIG. 5, it is necessary to correct the press mold every time the operating force is adjusted as described above.

The one shown in the figure has two upper and lower doors 59, and the boxes are opened and closed separately. In the case of such a slide type, the support structure of the door 59 is as shown below. A pair of left and right rails 57 are attached to both side edges of the box body in the console box along the length direction (front-back direction). Both rails 57 have channel grooves 58 in upper and lower stages, and both doors 59 are provided in each groove 58.
The support member 62 corresponding to is slidably fitted. The support member 62 is attached by being fitted into the notch recesses 60 formed on the respective side edges of both doors 59. A spring member 70 is housed in each of the support members 62, and
The press-contact piece 67 formed on the upper part of 2 is pressed against the inner surface of the rail 57 to apply a predetermined operation load.

[0005]

In the case of the above, the support member 62 is attached to the door 59 by locking the locking claw 64 formed on the support member 62 in the locking recess 61 on the notch recess 60 side. Is going by.
By the way, the width dimension of the gap between the support member 62 and the rail 57 may vary after assembly due to a dimensional error in molding the console, the door 59 and the like. If this gap exceeds the set range, the door 59
If there is rattling on the whole, and on the contrary, if it falls below the rail 57
It will cling to the hands and make the operation difficult. That is,
This is because, in the conventional case, the support member 62 is mounted in a state of being positioned with respect to the door 59 and the above-mentioned gap adjustment is not possible. In view of the conventional problems described above, an object of the present invention is that even if there is a variation in the distance between the pair of rails with respect to the sliding body, the variation can be satisfactorily dealt with, and the sliding body with respect to the pair of rails can be provided. It is possible to provide a support structure for a sliding body that can prevent rattling and galling (biting). Further, in view of the above-mentioned conventional problems, an object of the present invention is to provide a support member for a sliding body in which there is no variation in the pressure contact force of the sliding body to the inner surface of the pair of rails with respect to the sliding body, and a support for the sliding body using the same. To provide the structure.

In the case of the above, as shown in FIG. 5, the spring member 70 has an arc shape with a convex upper portion, and by adjusting the bending degree of the arc or the thickness, the inner surface of the rail is adjusted. I adjusted the contact pressure. here,
In consideration of spring back (reaction force works against force to be bent) at the time of press forming for bending the leaf spring, the plate spring is usually bent at a larger angle than the intended bending angle. However, there is variation in the return angle due to springback, and due to this variation in the bending angle of the spring member also occurs, which causes variation in the pressure contact force to the rail inner surface. In view of the above-mentioned conventional problems, an object of the present invention is to provide a support member for a sliding body in which the pressure contact force of the sliding body with respect to the inner surfaces of a pair of the sliding body does not vary, and a supporting structure for the sliding body using the same. To do.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. In FIG. 5, reference numeral 1 is a console box for an automobile, which is mounted between the driver's seat and the passenger seat. The entire console box 1 is provided with a box portion 2 that opens upward, and a sliding body (hereinafter referred to as a door) 9 is provided on the upper portion of the box portion 2. The console box 1 has a frame portion 5, and the frame portion 5 has a pair of rails 7 for opening and closing the door 9 in the front-rear direction of the vehicle. The left and right rails are arranged so as to face each other. Both rails 7 are both made of a metal material such as iron and a resin material such as nylon resin or ABS resin, and the inner surface of the groove 8 constituting the rail is processed with polytetrafluoroethylene (hereinafter referred to as PTFE). Has been applied.

FIG. 1 shows a spring member 12 at the edge of the door.
FIG. FIG. 2 is a schematic perspective view showing the door 9, and the edge 27 facing both rails 7 in FIG. 1 is the position of the portion A in FIG. 2, and one of the edges facing the both rails 7 on the door 9 side. The portions are notched in a U-shape, and are a pair of left and right notched recesses 10. The spring member 1 is made of a soft and elastic synthetic resin material such as polypropylene elastomer in each of the notched recesses 10.
2 is attached and fitted along the groove 8 so as to be slidable. The spring member 12 has elastic pieces 17 formed in an arc shape cut out on the upper surface and the lower surface thereof, and a slight bending deformation is allowed by abutting the upper and lower sides of the rail 7. Further, it is possible to eliminate rattling in the vertical direction between the rail and the door.
The spring member 12 has a U-shaped cross section and is press-fitted to the edge of the door 9 facing the rail 7. Further, a cutout recess 10 is formed on the edge. Furthermore, below the left and right ends of the spring member 12,
A locking claw 14 is provided upright, and the spring member 12 is fixed to the door 9 by contacting the surfaces 11 and 13 at the cutout recess 10.

The thin spring material of the spring member 12 is bent in the front-back direction to form the above-mentioned pressure contact material 17, and the arc-shaped elastic piece 19 is flexibly deformed from the side edge of the other end. It is made possible. This resilient piece 19 prevents the rattling of the door 9 in the left-right direction orthogonal to the movement of the door 9 by pressing the spring member 12 to the door 9 while pressing it against the rail wall surface 15.

The material of the spring member 12 may be resin, and resins such as polyacetal, polyethylene and polybutylene terephthalate are preferably used.

With the spring member 12 mounted, the entire width of the door 9 including the spring member 12 may be set larger than the maximum value of the variation limit of the distance between the rails 7. This example is formed as described above. When assembling both doors 9, each spring member 1
2 is mounted in each notch recess 10. That is, by pressing the spring member 12 against the cutout recess 10 and pushing it in, the locking claws 14 are brought into contact with the surfaces 11 and 13 of the cutout recess 10. At this time, the cutout recess 10
The spring member 12 is fixed to the edge 5 of the door 9 by the gripping force by pushing into the edge 5 of the door 9 and the locking of the locking claws 14 to the edge 5 of the door 9.

After the spring members 12 are mounted on both doors 9 in this manner, they are mounted on the console side, respectively. That is, the spring member 12 is adapted while inserting the corresponding door 9 into each rail 7, but as described above, the spacing between the left and right rails 7 may vary. However, according to this example, when the gap is wide, the spring member 12 is pushed out by the resilient piece 19 and the entire door 9 is widened. Therefore, if the variation is within the allowable range, the spring is released. The member 12 contacts the side surface inside the rail 7, and rattling can be prevented. vice versa,
When the space is narrow, each spring member 12 is pushed inward by the rail 7 against the resilient piece 19, and the width of the entire door 9 is reduced according to the space. Then, the door 9 is mounted without being seized, and in this case, the spring force of the elastic piece 19 becomes a part of the operation load of the door 9.

As described above, since the spring member 12 is displaced in the width direction of the door 9 according to the variation in the distance between the door 9 and the rail 7, the variation in the above distance is absorbed, that is, the door 9 is elastically repelled to the left and right. Since the center of the door 9 is automatically adjusted by the balance of the spring force from the piece 19, the door 9 is supported without rattling, and its smooth operation is possible.

In addition, since the inner surface of the rail 7 is subjected to PTFE processing, the smoothness of sliding of the spring member 12 is further ensured, and the sliding noise can be further reduced.
Further, it is more effective to coat the spring member 12 with fluororesin. Although this example illustrates the case where the present invention is applied to a console box for an automobile, the present invention can also be applied to a drawer type ashtray or a small container for an automobile. FIG. 3 is a view showing a state in which the spring member 12 is assembled to the door 9.

Further, locking claws 14 are provided upright on the lower sides of the left and right ends of the support member 12, and a locking recess 16 is recessed in the lower surface of the cutout recess 10. Then, a support member 12 formed of a soft and elastic synthetic resin material such as polypropylene-based elastomer is attached to each of the notch recesses 10, and slides along the groove 8 with respect to the groove 8. It is fitted so that it can be displaced.

A flat leaf spring 20 is installed in the support member 12, and an elastic force is applied to the pressure contact piece 18 by the leaf spring. The pressure contact piece 18 is in pressure contact with the rail upper surface 22 to prevent the door 9 from rattling in the vertical direction.

The pressure contact piece 18 has a leaf spring abutment piece 24 that abuts at a substantially central portion of the flat leaf spring in a direction substantially perpendicular to the longitudinal direction of the leaf spring. It is preferable to have a leaf spring support piece 26 that supports both ends of the leaf spring 20 so that the leaf spring 20 is positioned substantially in the center of the support member 12.

The material of the support member 12 may be resin, and resins such as polyacetal, polyethylene and polybutylene terephthalate are preferably used.

With the support member 12 mounted, the entire width of the door 9 including the support member 12 is equal to that of the rails 7.
It is recommended to set it larger than the maximum value of the variation limit of the interval. This example is formed as described above. When assembling the both doors 9, as shown in FIG. 7, each support member 12 is mounted in each notch recess 10. That is, the support members 12 are pressed against the cutout recesses 10 and pushed in, whereby the locking claws 14 are fitted into the lock recesses 16 of the cutout recesses 10. At this time, the support member 12 is fixed to the edge 27 of the door 9 by the grip force by pushing it into the notch recess 10 and the locking of each locking claw 14 with the locking recess 16.

Thus, each support member 12 is attached to both doors 9
After mounting on the console, mount on the console side respectively.
That is, the support member 12 is fitted while inserting the corresponding door 9 to each rail 7. Support member 1
The support member 12 can be brought into contact with the upper portion of the rail 7 by the pressure contact piece 18 formed in an arc shape on at least the upper surface thereof, and the rattling of the sliding member can be prevented.

As described above, since the support member 12 is displaced in the vertical direction of the door 9 according to the variation in the distance between the door 9 and the rail 7, the variation in the above distance is absorbed, that is, the door 9 is inside the support member 12. Since the center of the leaf spring is automatically adjusted by the balance of the spring force of the leaf spring, the door 9 is supported without rattling, and its smooth operation is possible.

In addition, since the inner surface of the rail 7 is subjected to PTFE processing, the smoothness of sliding of the spring member 12 is further ensured, and the sliding noise can be further reduced.
In addition, although this example illustrated the case where it was applied to the console box for automobiles, it can also be applied to the drawer type ashtray for automobiles.

As a method of mounting the flat leaf spring 20 on the spring member 12 used in the present invention, the leaf spring 20 is inserted into the support member 12 as shown in FIG. Contact piece 24 and support member 1
The leaf spring 20 is supported by three points of the leaf spring support pieces 26 located at both ends of the plate spring 2.
