 An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an exploded perspective view of a slide rail such as a drawer according to the present invention.

The slide rail 1 is composed of an outer rail 2, an inner rail 3 and a ball retainer 4, and the inner rail 3 is moved in the longitudinal direction of the outer rail 2 via a large number of balls 43 held by the ball retainer 4. It is slidably attached.

The outer rail 2 is a strip-shaped metal plate body having a C-shaped cross section, and includes a substrate 21 and bent side edge portions 22 in which upper and lower side edge portions of the substrate are bent toward the substrate inner surface 21a side. The substrate 21 is a flat plate portion fixed to a stationary portion such as a cabinet body.

In addition, at the front end of the board 21 on the pull-out side, one piece of the engaging piece 23 is formed by cutting and raising to the side of the board inner surface 21a, and the board 21 behind the engaging piece 23 has a ball. Similarly, a stopper 27 is provided to prevent the retainer 4 from hitting the front end portion on the pull-out side and sliding the retainer 4 forward. The stopper 27 is a protruding piece obtained by cutting and raising a part of the substrate 21 toward the substrate inner surface 21a.

Further, a stopper 28 is provided at the rear end of the base plate 21 to prevent the rear end of the ball retainer 4 from hitting and to prevent the retainer from sliding rearward. The stopper 28 is a rectangular protrusion that raises a part of the substrate 21 toward the substrate inner surface 21a.

Further, near both ends of the board 21, mounting holes 29a for inserting a stopper (not shown) for fixing the outer rail 2 to a fixed portion such as a cabinet body are formed.

Reference numeral 24 in the drawing denotes a synthetic resin guide member attached to the front end portion of the substrate 21 via a mounting hole 29b. When the inner rail 3 is mounted, a pair of upper and lower guide pieces 24a are provided. It will guide the inner rail 3.

The inner rail 3 is a strip-shaped metal plate having a substantially U-shaped cross section and having the same length as the outer rail 2. The inner rail 3 has a board 31 and bent side edges formed by bending the upper and lower edges of the board 31 toward the board inner surface 31a. 32 and 32. The substrate 31 is a flat plate portion to which a drawer or the like is attached.

At the rear end of the board inner surface 31 a on the pull-out side, when the inner rail 3 to which a drawer or the like is attached is pulled out from the outer rail 2 to which the cabinet body or the like is attached, the inner rail 3 is removed from the outer rail 2. A stopper 35 is attached to keep the projecting state.

The stopper 35 is a strip-shaped plate plate (elastic plate) that is bent in a substantially V shape toward the front, and includes a fixing portion 351, an inclined portion 352, and an operating portion 353. Consists of.

The fixing portion 351 is a portion fixed to the substrate 31, and is provided with a plurality of holes 351 a into which a stopper for fixing is inserted.

The inclined portion 352 is bent and extends obliquely upward from the fixed portion 351, and at the same time, the one side portion near the operation portion 353 has a rectangular shape with which the engaging claw 23 is engaged. An engagement cutout portion 352a is formed.

As will be described later, the operating portion 353 is an operating protrusion that releases the engagement state between the engaging claw 23 and the engaging cutout portion 352 a, and faces the inner rail 3 side in front of the inclined portion 352. It is bent into a letter shape.

Further, a stopper for fixing the inner rail 3 to a movable portion such as a drawer or a stopper for fixing the fixing portion 351 of the stopper 35 is inserted at both ends and the central portion of the substrate 31. The mounting holes 33 and 35 are formed by folding.

The ball retainer 4 is a strip-shaped metal thin plate member set to have a length of about 1/3 of the outer rail 2 and the inner rail 3, and has a base plate 41 and upper and lower side edges bent to the base outer surface 41 b side. The ball holding portion 42 and a plurality of balls 43 rotatably held by the ball holding portion 42.

Next, the operation of the slide rail 1 thus configured will be described.

With the rear ends of the outer rail 2, the inner rail 3, and the ball retainer 4 aligned, the other end 45 of the ball retainer 4 hits the stopper 28 of the outer rail 2 and the inclined portion 352 of the stopper 35 causes the ball retainer 4 to move. Is in contact with the outer surface 41b of the substrate (see a in FIG. 2).

When the drawer attached to the inner rail 3 is pulled out from this state, the inner rail 3 slides, and along with this, the ball retainer 4 also slides by half of the moving distance of the inner rail 3. Eventually, the tip end portion 44 of the ball retainer 4 hits the stopper 27, and the ball retainer 4 stops.

At the same time, the engaging claw 23 of the outer rail 2 engages with the engaging notch 352a of the stopper 35 provided at the rear end of the inner rail 3 to stop the sliding of the inner rail 3 (FIG. 2). B)).

In this state, the operating portion 353 of the stopper 35 is in a state of protruding to the outside of the outer rail 2. As a result, the drawer attached to the inner rail 3 is maintained in a state of protruding from the cabinet body to which the outer rail 2 is attached.

Further, when pulling out the inner rail 3 to which the drawer is attached from this state, the operating portion 353 of the stopper 35 is pushed toward the inner rail 3 side with a fingertip, and the engaging claw 23 and the engaging cutout portion 352a are formed. The drawer with the inner rail 3 is pulled out while maintaining the state in which the engagement with and is released.

When the drawn drawer is mounted on the outer rail 2 again, when the inner surface of the bent side edge portion 32 above the inner rail 3 is pressed against the upper surface of the engaging claw 23, the inner rail 3 is removed. It is easily pushed into the outer rail 2.
