Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a support structure related to a sliding body such as a sliding door of a console box mounted on an automobile or the like, or an ashtray.
[0002]
[Prior art]
As shown in FIG. 10, the door of the console box has a type that slides and opens as well as a type that opens by turning. In the figure, doors 59 are provided in two upper and lower stages, and the box is opened and closed separately. In the case of such a slide type, the support structure of the door 59 is as follows. 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-rear direction). Both rails 57 have two upper and lower channel grooves 58, and support members 62 corresponding to both doors 59 are slidably fitted in the respective grooves 58. The support member 62 is attached by being fitted into a notch recess 60 formed on each side edge of both doors 59. A spring member 70 is accommodated in both support members 62, and a 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.
[0003]
Further, the console box door is of a type that slides and opens as shown in FIG. In order to obtain smooth operability when sliding on the guide rail, the spring is placed in a resin box (injection molded product), and resin (polyacetal, polyethylene, polybutylene terephthalate, etc.) is used for sliding with the rail. It is common to have a structure that touches. When the door has a sliding structure, the operating force when manually opening and closing depends on the sliding resistance (frictional force) between the rail and the plastic box, which is largely due to the force that the built-in spring pushes up the plastic box. It is. Therefore, the adjustment to increase or decrease the operating force requires increasing the thickness of the leaf spring or changing the shape. As shown in FIG. 5, since the leaf spring is manufactured by press molding, it is necessary to correct the press mold each time the operating force is adjusted as described above.
[0004]
In the figure, doors 59 are provided in two upper and lower stages, and the box is opened and closed separately. In the case of such a slide type, the support structure of the door 59 is as follows. 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-rear direction). Both rails 57 have two upper and lower channel grooves 58, and support members 62 corresponding to both doors 59 are slidably fitted in the respective grooves 58. The support member 62 is attached by being fitted into a notch recess 60 formed on each side edge of both doors 59. A spring member 70 is accommodated in both support members 62, and a 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.
[0005]
[Problems to be solved by the invention]
In the case of the above, the support member 62 is attached to the door 59 by engaging the locking claw 64 formed on the support member 62 with the locking recess 61 on the recess 60 side. By the way, due to a dimensional error at the time of molding of the console, the door 59, and the like, the width dimension of the gap between the support member 62 and the rail 57 may vary after the assembly. If this gap exceeds the set range, the entire door 59 is rattled, and conversely, if it is less than the set range, it will bite the rail 57 and make the operation difficult. That is, in the conventional case, the support member 62 is attached in a state of being positioned with respect to the door 59, and the above-described clearance adjustment cannot be performed. In view of the above-described conventional problems, the object of the present invention is to cope with the variation even if there is variation in the distance between the pair of rails relative to the sliding body. It is possible to provide a support structure for a sliding body that can prevent rattling and galling (biting). Furthermore, in view of the above-described conventional problems, the object of the present invention is to provide a support member for a sliding body in which there is no variation in the pressing force of the sliding body on the inner surface of a pair of rails with respect to the sliding body, and support for the sliding body using the same. To provide a structure.
[0006]
In the case of the above, as shown in FIG. 5, the spring member 70 has an arc shape with a convex upper part, and by adjusting the degree of bending of the arc or adjusting the thickness, the pressure contact force to the rail inner surface can be increased. I was adjusting. Here, in consideration of a spring back (a reaction force acts on the force to bend) during press forming for bending the leaf spring, the bending is usually larger than the target bending angle. However, the return angle due to the spring back varies, and as a result, the bending angle of the spring member also varies, and therefore the pressure contact force on the inner surface of the rail also varies. In view of the above-described conventional problems, an object of the present invention is to provide a support member for a sliding body that does not vary in the pressure contact force of the sliding body to the inner surface of a pair of rails with respect to the sliding body, and a support structure for the sliding body using the same. There is to do.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below. In FIG. 5, reference numeral 1 denotes an automobile console box, which is mounted between a driver seat and a 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 above 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 formed of a metal material such as iron and a resin material such as nylon resin and ABS resin, and the inner surface of the groove 8 constituting the rail is processed with polytetrafluoroethylene (hereinafter referred to as PTFE). Is given.
[0017]
FIG. 1 is a view in which a spring member 12 is to be attached to an edge of a door. FIG. 2 is a schematic perspective view showing the door 9, and an edge 27 facing both the 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 cut out in a U-shape, and are a pair of left and right cutout recesses 10 respectively. A spring member 12 made of a soft and elastic synthetic resin material such as a polypropylene-based elastomer is attached to each of the notch recesses 10 and is fitted along the groove 8 so as to be slidable. Yes. The spring member 12 has an upper surface and a lower surface formed with cut pieces 17 formed in a circular arc shape, and is allowed to be slightly bent and deformed by contacting the upper and lower sides of the rail 7. Further, it is possible to eliminate backlash in the vertical direction between the rail and the door. The spring member 12 has a U-shaped cross section and is press-fitted into an edge of the door 9 that faces the rail 7. A cutout recess 10 is formed at the edge. Further, locking claws 14 are erected on the lower side of the left and right ends of the spring member 12, and the spring member 12 is fixed to the door 9 by contacting the surfaces 11, 13 at the notch recess 10. .
[0018]
The spring member 12 is formed by bending a thin spring material in the front-rear direction, thereby forming the above-described pressure contact material 17, and an arc-shaped elastic piece 19 is formed so as to be able to bend and deform from the side edge of the other end. Has been. The elastic piece 19 prevents the rattling of the door 9 in the left-right direction perpendicular to the movement of the door 9 by being pressed against the rail wall surface 15 in a state where the spring member 12 is assembled to the door 9.
[0019]
Moreover, the material of the spring member 12 should just be resin, and resin, such as a polyacetal, polyethylene, a polybutylene terephthalate, is used suitably.
[0020]
In the state where the spring member 12 is mounted, the full width of the door 9 including the spring member 12 may be set to be larger than the maximum value of the variation limit of the distance between the rails 7. This example is formed as described above. In assembling the doors 9, the spring members 12 are mounted in the cutout recesses 10. That is, by pressing the spring member 12 against the notch recess 10 and pressing it, the respective locking claws 14 are brought into contact with the surfaces 11 and 13 of the notch recess 10. At this time, the spring member 12 is fixed to the edge 5 of the door 9 by the gripping force by pushing into the notch recess 10 and the engagement of the locking claws 14 to the edge 5 of the door 9.
[0021]
Thus, after each spring member 12 is mounted on both doors 9, it is mounted on the console side. That is, the spring member 12 is adapted while inserting the corresponding door 9 into each rail 7, but as described above, the interval between the left and right rails 7 may vary. However, according to this example, when the interval is widened, the spring member 12 is pushed out by the elastic piece 19 and the entire door 9 is widened. The member 12 abuts against the side surface in the rail 7 and can prevent rattling. On the contrary, when the interval is narrowed, each spring member 12 is pushed inward against the projectile piece 19 by the rail 7, and the width of the entire door 9 is reduced according to the interval. Thus, the door 9 is mounted without being squeezed. In this case, the spring force of the elastic piece 19 becomes a part of the operation load of the door 9.
[0022]
Thus, since the spring member 12 is displaced in the width direction of the door 9 in accordance with the variation in the distance between the door 9 and the rail 7, the variation in the distance is absorbed. Therefore, the door 9 is supported without rattling and can be smoothly operated.
[0023]
In addition, since the inner surface of the rail 7 is subjected to PTFE processing, the sliding smoothness 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 a fluororesin. In addition, although this example illustrated the case where it applied to the console box for motor vehicles, it is also possible to apply to the drawer-type ashtray, accessory case, etc. for motor vehicles. FIG. 3 is a view showing a state in which the spring member 12 is assembled to the door 9.
[0024]
The method of forming the spring member 12 used in the present invention is very simple. As a manufacturing process, as shown in FIG. 4, the target spring member 12 can be formed by punching two locations in one leaf spring to form a notch 21, bending at a line 23, and further bending at a line 25. . Therefore, particularly large-scale equipment and processes are not required.
[0025]
Further, when the outer surface of the spring member 12 is coated with a fluororesin, the slidability is further improved.
[0026]
As another embodiment of the present invention, FIG. 6 shows a schematic perspective view of a support member. The support member 12 is formed by cutting out a pressure contact piece 17 formed in an arc shape on at least the upper surface thereof, and is allowed to be slightly deformed by contacting the upper portion of the rail 7. The support member 12 has a U-shaped cross section and is press-fitted into an edge of the door 9 facing the rail 7. A cutout recess 10 is formed at the edge. Further, a locking claw 14 is erected on the lower side of the left and right ends of the support member 12, and a locking recess 16 is formed on the lower surface of the notch recess 10. A support member 12 made of a soft and elastic synthetic resin material such as a polypropylene-based elastomer is attached to each of the notched recesses 10, and both slide along the groove 8 with respect to the groove 8. It is fitted so that it can be displaced.
[0027]
A flat leaf spring 20 is installed in the support member 12, and the pressure contact piece 18 is given an elastic force by the leaf spring. The pressure contact piece 18 is pressed against the rail upper surface 22 to prevent the door 9 from rattling in the vertical direction.
[0028]
The pressure contact piece 18 has a leaf spring abutting piece 24 that abuts at a substantially center of the flat leaf spring in a direction substantially perpendicular to the longitudinal direction of the leaf spring, and the leaf spring 20 is provided in the support member 12. It is preferable to have leaf spring support pieces 26 that support both ends of the leaf spring 20 so that is located at the approximate center in the support member 12.
[0029]
Moreover, the material of the support member 12 should just be resin, and resin, such as polyacetal, polyethylene, a polybutylene terephthalate, is used suitably.
[0030]
In the state where the support member 12 is mounted, the full width of the door 9 including the support 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. In assembling the doors 9, the support members 12 are mounted in the cutout recesses 10 as shown in FIG. 7. That is, by pressing the support member 12 against the notch recess 10 and pushing it in, the locking claws 14 are fitted into the locking recesses 16 of the notch recess 10. At this time, the support member 12 is fixed to the edge 27 of the door 9 by the gripping force generated by pushing into the notch recess 10 and the locking claw 14 being locked to the locking recess 16.
[0031]
Thus, after each support member 12 is mounted on both doors 9, it is mounted on the console side. That is, the support member 12 is adapted while inserting the corresponding door 9 into each rail 7. 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 of the support member 12, and rattling of the sliding material can be prevented.
[0032]
Thus, 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 distance is absorbed, that is, the door 9 is a leaf spring in the support member 12. Therefore, the door 9 is supported without rattling and can be smoothly operated.
[0033]
In addition, since the inner surface of the rail 7 is subjected to PTFE processing, the sliding smoothness 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 applied to the console box for motor vehicles, it is also possible to apply to the drawer-type ashtray for motor vehicles.
[0034]
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. The leaf spring 20 is supported at three points of the leaf spring support pieces 26 located at both ends of the support member 12.
[0035]

【The invention's effect】
As described above, since the present invention is a support structure of a sliding body using a support member, it can suppress not only the right and left but also the back and forth rattling with a simple structure, and a particularly complicated molding machine is also required. Instead, the structure can be simplified and the slidability can be improved.
[0036]
According to a second aspect of the present invention, the pressure contact piece includes a leaf spring abutting piece that abuts at a substantially center of the leaf spring in a direction substantially perpendicular to the longitudinal direction of the leaf spring. as spring is positioned substantially at the center of the support member, because it is supported member sliding body according to claim 1 having a plate spring supporting piece for supporting the both ends of the plate spring, the pressing force of the pressing member There is an effect that the variation becomes smaller.
[0037]
According to a third aspect of the present invention, in a sliding body that is movably installed between a pair of rails attached to the fixed body side, an edge of the sliding body that opposes the rail engages with a proper position of the sliding body. A support member having a latching claw in a part thereof and slidably fitted to both rails and provided with a leaf spring has a slight displacement in a direction perpendicular to the sliding direction of the sliding body. Each of the support members is assembled in a permissible state, and the support member is formed with a pressure-deformable deformable pressure contact piece that presses against a side edge of the sliding body and abuts against an upper surface of the rail, and the pressure contact piece is flat. The support structure of the sliding body is characterized by the fact that elastic force is applied by a flat leaf spring, so the variation in the pressure contact force of the support member to the rail is reduced, and the sliding body always slides with a constant force The effect of being able to There is.
