[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide rail fixed to an inner surface of a side plate of a cabinet and an opposing surface such as a drawer or a shelf.

[0002]

2. Description of the Related Art Conventionally, as this kind of slide rail, a vertical member and a horizontal roller are supported by a cabinet member fixed to a cabinet side and a trower member fixed to a drawer side, respectively. It has been known.

[0003]

However, in the above-mentioned conventional slide rail, the vertical roller is used for load transmission,
Since the horizontal rollers are each assigned a function for stabilizing in the horizontal direction, the usage mode is limited and multipurpose use is not possible.Also, the shape and structure of the cabinet member and the drawer member are different, and both members are different. In addition to the above, a roller support member (retainer) is required, and as a result, the number of parts is large and the structure is complicated. Therefore, its production and assembly are troublesome and time-consuming.
Production costs are high.

In view of the above-mentioned problems of the prior art, the present invention has a cabinet member and a drawer member which have the same shape and are formed so as to receive a thrust load in both directions of a tension direction and a compression direction. Rollers and horizontal rollers are designed not only to receive loads in the radial direction but also to stabilize them in the horizontal direction.This makes it possible to use them for multiple purposes such as vertical, horizontal and single-sided specifications. Is the purpose.

[0005]

According to the present invention, in order to achieve the above object, a cabinet member and a drawer member fixed to an inner surface of a side plate of a cabinet and a facing surface portion of a drawer with respect to the cabinet are orthogonal to each other. A first vertical flange and a first horizontal flange, and second second flanges respectively extending from ends of the two flanges so as to face the same flange.
The vertical flange and the second horizontal flange form one corner of the angular pipe with an open cross-sectional shape and have substantially the same shape. At one end, in a state where the two members are opposed to each other so as to be slidable in the length direction, the other members are located on the other member.
A vertical roller and a horizontal roller, which are respectively rotatably engaged and disposed between the second horizontal flanges and between the first and second vertical flanges, are fixed in the longitudinal direction of the members. It is an object of the present invention to provide slide rails each of which is pivotally supported at an interval.

[0006]

Since the cabinet member and the drawer member are formed in the same shape, by pulling them in opposite directions, the vertical roller and the horizontal roller of the pivot are supported at one end of the cabinet member by the first and second drawer members. The two flanges are disposed in engagement with each other between the horizontal flanges and between the first and second vertical flanges. On the other hand, a vertical roller and a horizontal roller pivotally supported by the drawer member are respectively disposed between the first and second horizontal flanges and between the first and second vertical flanges of the cabinet member.

Accordingly, the vertical roller and the horizontal roller of both the cabinet and the drawer can roll with respect to the first and second horizontal flanges and the first and second vertical flanges of the other member. Therefore, both members are slidable in a direction in which the members are extended or contracted when an external force is applied in the length direction.

When this is used to attach a drawer to a cabinet, a vertical rib of an L-shaped mounting bracket is fixed to an inner surface of a side plate of the cabinet by a screw, and a horizontal rib is provided on a cabinet member. The first horizontal rib is placed and fixed. On the other hand, in the drawer member, the side plate or the bottom plate of the drawer is placed and fixed on the first horizontal flange, whereby the drawer is slidably mounted. The above is the vertical specification of the slide rail, and the vertical rollers of both the cabinet and the drawer receive the vertical load of the drawer. On the other hand, the horizontal rollers of both members serve to stabilize the drawer in the lateral direction.

Further, if the cabinet member is fixed to the side plate of the cabinet by changing the direction of 180 ° in the above vertical specification, the horizontal specification of the slide rail is obtained. In this case, since the first vertical flange of the drawer member is in a horizontal state, the drawer is placed thereon and fixed. In such a horizontal specification, both horizontal rollers (actually in a vertical state) receive a vertical load, and both vertical rollers (actually in a horizontal state) stabilize the horizontal direction. Become.

[0010] Further, the drawer or the shelf or the like can be supported by the slide rail at two upper and lower locations with respect to the cabinet according to the above-mentioned vertical specification or horizontal specification so as to be a one-side specification. In the case of the one-side specification, naturally, the force due to its own weight, such as drawer, acts downward, so that the upper slide rail receives a thrust load in the tension direction, and the lower slide rail applies a thrust load in the compression direction. A load is applied, whereby the radial load can be sufficiently received by the slide rail on one side.
