Abstract

A slide rail includes: a rail assembly 2 ; an inner rail 4 mounted on the rail assembly 2 , and slidable in a longitudinal direction of the rail assembly 2 ; and a locking arm 5 a rear end portion of which is secured to a surface of the inner rail 4 facing the rail assembly 2 , and a front end portion of which is a free end, wherein the locking arm 5 has a lock protrusion portion 5 a that, when pulling out the inner rail 4 from the rail assembly 2 , locks slide at a predetermined position, and wherein the rail assembly 2 has a lock hole 2 a for catching the lock protrusion portion 5 a.

First claim

The invention claimed is:

1. A slide rail comprising:
a rail assembly;
an inner rail accommodated in the rail assembly, and slidable in a longitudinal direction of the rail assembly; and
a locking arm a rear end portion of which is secured to a surface of the inner rail facing the rail assembly, and a front end portion of which is a free end,
wherein the locking arm has a lock protrusion portion that, when pulling out the inner rail from the rail assembly, locks slide at a predetermined position,
wherein the rail assembly has a lock hole for catching the lock protrusion portion,
wherein a lock of the slide of the inner rail is released when the front end portion of the locking arm is pressed toward the inner rail and the lock protrusion portion of the locking arm disengages from the lock hole of the rail assembly,
wherein the locking arm has a bent portion formed by hemming, in the front end portion, and
wherein the inner rail has, at a position facing the bent portion formed by hemming, a lock clearance hole for letting the bent portion escape when releasing the lock of the slide.

2. The slide rail according to claim 1 , wherein the rail assembly has no protrusion on a surface facing the inner rail.

3. The slide rail according to claim 2 , wherein the lock protrusion portion is two upper and lower bent portions arranged in a transverse direction, at a predetermined position between the front end portion and the rear end portion of the locking arm.

4. The slide rail according to claim 1 , wherein the lock protrusion portion is two upper and lower bent portions arranged in a transverse direction, at a predetermined position between the front end portion and the rear end portion of the locking arm.

5. An equipment mounting rack comprising
a slide rail attached to both sides of a rack body, in a front-back direction,
wherein the slide rail includes:
a rail assembly;
an inner rail accommodated in the rail assembly, and slidable in a longitudinal direction of the rail assembly; and
a locking arm a rear end portion of which is secured to a surface of the inner rail facing the rail assembly, and a front end portion of which is a free end,
wherein the locking arm has a lock protrusion portion that, when pulling out the inner rail from the rail assembly, locks slide at a predetermined position,
wherein the rail assembly has a lock hole for catching the lock protrusion portion,
wherein a lock of the slide of the inner rail is released when the front end portion of the locking arm is pressed toward the inner rail and the lock protrusion portion of the locking arm disengages from the lock hole of the rail assembly,
wherein the locking arm has a bent portion formed by hemming, in the front end portion, and
wherein the inner rail has, at a position facing the bent portion formed by hemming, a lock clearance hole for letting the bent portion escape when releasing the lock of the slide.
