Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide rail mechanism, and more specifically, to a relative movement of a fixed member along a fixed track, or The present invention relates to a slide rail mechanism for guiding a movable member which is made to relatively move in a certain stroke.

2. Description of the Related Art Conventionally, for example, as shown in FIG. 2 of the accompanying drawings, several drawers 1 are arranged one above the other, and each drawer 1 is
In order to make the drawer 1 in and out smoothly in the rearranging box 20 which can be taken in and out,
Between the inner surface of the side wall of the drawer 1 of each drawer 1 and the outer surface of the side wall of each drawer 1 facing it,
It is common practice to provide the slide rail mechanism 2. And as this slide rail mechanism 2,
For example, as shown in FIG. 3, it comprises an inner rail 3 and an outer rail 4 which are slidably fitted to each other and have flat bottoms and which are substantially U-shaped in cross section. It is attached to the outer surface of the side wall of the rail in the pull-out direction with the opening facing outward, for example, at a position approximately half the height thereof, at the bottom of the rail 3, and 20 drawers 1 such as a storage box. On the inner surface of the side wall of the loading / unloading part, the outer rail 4 is attached at the position corresponding to the position of the inner rail 3 with its opening inside.

In this way, when the drawer 1 is taken in and out, the drawer 1 is guided by the inner rail 3 attached to the side wall of the drawer 1 and the outer rail 4 attached to the inner surface of the side wall of the storage box 20 such as a storage box. By doing so, the putting in and out can be performed smoothly.

However, according to such a configuration, there is no connecting member between the inner and outer rails 3 and 4, so that, for example, once the drawer 1 is pulled out, this is arranged in a predetermined box such as a rearranging box 20. Drawer 1 to return to position
In addition, it was necessary to apply a pushing force from the outside. This is because, with such a configuration, no restoring force acts between the drawer 1 and the storage box 20 or the like.

In order to solve this and to give a restoring force between the inner and outer rails 3 and 4, it has been attempted to connect them with an appropriate restoring mechanism.In this case, this restoring mechanism is configured. After attaching each part separately to the inner and outer rails 3 and 4, respectively, when fitting the drawer into the storage box 20 etc., both parts are designed to be combined with each other. In this case, the relative mounting positions of both parts require a certain degree of accuracy, which makes mounting them difficult, and the combination and adjustment of both parts after mounting are complicated. It was

Further, a certain amount of extra space is required for the fixing member and the moving member in order to mount these parts.

Therefore, the present invention can provide a restoring force to the slide rail mechanism, which is a guide member composed of such inner and outer rails, and is easy to install. The purpose is to obtain a slide rail mechanism with a tension device.

Means for Solving the Problems In order to achieve this object, the present invention relates to the first part of the accompanying drawings.
As shown in the figure, it consists of an inner rail (11) and an outer rail (12) which are fitted to each other, and these inner and outer rails (11, 12) are arranged at one end of them. It is characterized by a slide rail mechanism with a constant tension device which is mutually connected by a constant tension device (17).

In addition, the present invention installs a stopper member on a rearranging box or the like (20) and fixes the brake part to the outer rail (12), thereby suppressing and stopping the return movement of the inner rail (11). Doing is also a feature.

Embodiment Hereinafter, the present invention will be described in detail with reference to FIG. 1 of the accompanying drawings showing an embodiment thereof.

FIG. 1 is a perspective view showing a slide rail mechanism 10 according to the present invention.
The present invention will be described as being used in place of the slide rail mechanism 2 of the prior art in the same organizing box 20 as shown in FIG. 2 described above as having one example of the prior art. To do.

The slide rail mechanism 10 according to the present invention, as shown in FIG. 1, has an inner rail having a flat, substantially U-shaped cross section with a flat bottom portion which are slidably fitted together. 11 and the outer rail 12, which are assembled so that the openings face each other,
This point is substantially the same as that of the prior art shown in FIG. However, according to the present invention, in the vicinity of one end, which is deep in the drawing direction of the drawer 1 of the outer rail 2, in the U-shaped groove, the bottom is flat, and the cross-section is substantially U-shaped. Mounting bracket that has a surface
13 is fixed at its bottom, and on its opposite side wall, a shaft 14 is arranged parallel to the bottom and penetrating at a right angle to its longitudinal direction, and each end is attached to a fitting.
The bobbin-shaped constant-tension winding jig 16 is fixed to the side wall of 13 via a retaining ring 15 on the outside thereof, and the shaft 14 has a bobbin-shaped constant tension winding jig 16 between the opposing side walls of the retaining metal 13. It is attached, and one end of a known constant tension device 17 composed of a spiral spring or the like is fixed on the fixed tension device 17. After being wound around the mandrel of the tension winding jig 16 several times, the other end is fixed to the inner rail 11. For this reason, on the flat bottom surface of the inner rail 11, another mounting member 18 bent into a substantially chevron shape is provided near the end near the mounting position of the mounting member 13 on the outer rail 12.
Secured at one end and near the raised other end to fitting 18 or inner rail 11
In the cut-and-raised portion formed by cutting and raising the end near the mounting bracket 13 of the flat bottom in a mountain shape, the spiral spring which constitutes the constant tension device 17 either directly on the inner rail 11 or A screw 19 is fixed near the other end of the.

Although the present invention has the above-mentioned configuration, in using it, the inner rail 11 is used in the same manner as in the prior art.
The outer rail 12 and the outer rail 12 may be appropriately mounted on the outer surface of the side wall of the drawer 1 and the inner surface of the opposite side wall of the drawer portion of the organizing box 20, respectively. In this case, the inner and outer rails 1
To install 1,12, use the constant tension device 17 to fix both rails 11,12.
It can be easily carried out by placing the constant tension device 17 in a state in which an appropriate tension is applied or in a state in which the tension is appropriately relaxed in a state in which is connected. Also,
The tension exerted by the constant tension device 17 can be appropriately adjusted and set to an optimum one according to the weight of the drawer 1 including the internal volume of the drawer.

In this way, according to the present invention, the pulling-out of the drawer 1 or the pushing-in operation thereof can be carried out lightly and smoothly with the aid of the tension of the constant tension device 17.

Also, if necessary, the outer rail of the inner and outer rails 11
Both rails 1 in maximum withdrawal position for 12
An appropriate releasable stopper member (not shown) is installed between 1, 12, etc., and the constant tension device 17 is installed at this position.
Suppresses the return movement of the drawer 1 based on the restoring force of
On the other hand, at the push-in position of the drawer 1, another stopper member may be provided in order to suppress the pull-in by the constant tension device 17 having a restoring force.

Further, although the slide rail mechanism according to the present invention has been described above as being applied to the drawer of the organizing box, the present invention is not limited to such an application, and for example, the door is vertically moved. It goes without saying that it can also be applied to a closet that is attached to the open and close in a similar manner.

Effect of the Invention The present invention has the above-described structure and operation, and since the inner and outer rails 11 and 12 are integrated with the constant tension device 17, the inner and outer rails 11 and 12 can be attached to an adherend. The constant tension device 17 characteristics can be easily adjusted to the required values in this way, so that the restoring force of the constant adjustment device 17 can be utilized. It can be adjusted to the weight or friction of drawers, drawers such as drawers, or
The external force required for pushing can be minimizedBecause the constant tension device 17 can be made compact, it does not require a special storage space for that purpose, for example in the case of a drawer. In the open position, it can be installed with a margin in the space left between its back and the rear wall of the organizing box etc. The presence of the constant tension device 17 allows any drawer to be pulled out. It is possible to pull out or push in from a position with a small external force, when the slide rail mechanism according to the present invention is used, for example, in a door configured to move up and down,
By properly selecting the characteristics of the constant tension device 17 and, if necessary, cooperating with a stopper member, the door can be kept stationary at any position in the vertical direction. By providing an appropriate stopper member that can block the movement along the relative movement path of, it is possible to stop the moving member such as the drawer at an accurate planned position. It has many excellent effects.
