Description

The present invention temporarily stops the drawer, devices and the like from the main body, and pulls the drawer, devices and the like (moving side rail) from the main body (fixed side rail) by a simple operation as necessary. The present invention relates to a slide rail that can be pulled out and that can be mounted easily.

Conventionally, the slide rail is composed of a fixed side rail provided on a fixed side member such as a furniture body, a movable side rail slidable on the fixed side rail, and a ball retainer rotatably holding a ball between both rails. A guide member having a stopper projection is provided on the inner surface of the front end of the fixed rail, and the rear end of the stopper member is rotatably attached to the inner surface of the rear end of the movable rail in correspondence with the guide member. In the slide rail, the stopper member is a stopper step that contacts the rear surface of the stopper projection when the moving member is pulled out, an operation section that cancels the contact state of the stopper projection, and the stopper step always keeps the stopper projection. The elastic legs that are maintained at the abutting positions of the parts are integrally formed of a synthetic resin material.
(See Patent Document 1)

In this case, from the middle of pulling out the moving side member (moving side rail) to the maximum pulling position of the moving side member (moving side rail) (state where the stopper step contacts the stopper protrusion), the fixed side is always The rail was to be exposed in the fixed member.
That is, when the slide rail is used in a display case that is displayed by looking into the interior from above, such as a display case made of precious metal, the precious metal is stored so that the customer can see it or wear it. When it is necessary to take out the display tray from the inside of the display case, pull out the display tray (moving side member) to the outside of the display kale, and the fixed side rail will be exposed at the original position where the display tray was pulled out. It was supposed to hurt.

If the slide rail is used in a storage unit with a small vertical dimension and a large depth, when the moving rails (moving-side members such as drawers) are all extracted, there are multiple steps in the vertical direction. The fixed-side rails that are provided over almost the entire width in the depth direction impede the cleaning of the inside of the storage body, which requires more time and effort than necessary.

On the other hand, in the case of the slide rail, the ball retainer remains in the state where the moving side rail is pulled out and the ball retainer is arranged in the fixed side rail. When the removed moving-side rail is mounted on the fixed-side rail again, the remaining ball retainer needs to be positioned at the front end of the fixed-side rail. (Because the ball rotatably held by the ball retainer is interposed between the fixed side rail and the moving side rail.) Therefore, the ball retainer is inadvertently moved backward between the fixed side rail and the ball retainer. Therefore, it is necessary to provide a holding member for holding the ball retainer at the front end of the fixed side rail so that the ball retainer does not move.

On the other hand, if the retaining member is not provided, when mounting the extracted moving side rail to the fixed side rail again, check whether the ball retainer is located at the front end of the fixed side rail, or place it at the front end. It was necessary to do the work, and it was very complicated.
Further, in the case of the slide rail, since the stopper member is attached to the extracted moving side rail, the stopper member is directly exposed to the outside in the state where the moving side rail is extracted. Therefore, when the moving-side rail is carried with the moving-side member, the stopper member may be unexpectedly damaged due to a collision with another article.
