Abstract

PROBLEM TO BE SOLVED: To provide a locking mechanism of a slide rail for exactly maintaining a state of housing a drawer, slide shelf, etc., into a main body of a rack, cabinet, etc. SOLUTION: An inner rail 3 provided with guide rail parts 4 and 4 facing the inside surfaces of guide rail parts 2 and 2 so as to face outward at the top and bottom ends is freely slidably mounted at an outer rail 1 provided with the inwardly facing guide rail parts 2 and 2 at the top and bottom ends. The inside surface inner than the terminal of the outer rail 1 is provided with a lock member 7 for elastically pressing the inside surfaces of the guide rail parts 4 and 4 of the inner rail 3. As a result, the inner rail 3 is maintained in the housing position at all times while the inside surfaces of the guide rail parts 4 are held elastically pressed by the lock member 7.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide rail lock mechanism for maintaining a slide rail used for a drawer, a slide shelf or the like.

[0002]

2. Description of the Related Art A conventional slide rail lock mechanism includes:
As shown in FIGS. 4A and 4B, a C-shaped lock member 23 made of a spring material is provided on one of the inner rail 21 and the outer rail 22, that is, on the base end side of the inner rail 21, and the other, that is, on the outer rail 22. After the opening 23a of the lock fitting 23 is forcibly expanded by the provided stopper fitting 24, the opening 23a is formed.
Was returned to the old state and engaged to maintain the stored state of the slide rail.

[0003]

However, in the prior art described above, after the opening 23a of the lock fitting 23 is forcibly expanded by the stopper fitting 24, the braking of the inner rail 21 is once released. Therefore, not only may the drawer shock the main body of the rack, cabinet, etc., which stores it due to inertia, generating unpleasant noise, or adversely affecting the objects stored in the drawer, etc. In the installed rack, cabinet, etc., there is also a concern that the strong impact when the drawer is stored causes the stopper metal 24 of the other drawer to be disengaged from the lock metal 23 and the other drawer may come out of the storage location. there were.

SUMMARY OF THE INVENTION A lock mechanism for a slide rail according to the present invention, which has been made to solve the above-mentioned problems, comprises an outer rail provided with inward guide rails at upper and lower ends. An inner rail provided with guide rails facing the inner surface of the outer rail at the upper and lower ends is slidably attached, and the inner surface of the guide rail of the inner rail is elastically pressed against the inner surface closer to the inner end than the end of the outer rail. A lock member is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, preferred embodiments of the present invention will be described with reference to the drawings. 1 is an outer rail provided with an inwardly arcuate or V-shaped guide rail portion 2 at the upper and lower ends,
Reference numeral 3 denotes an inner rail slidably mounted in the outer rail 1. At upper and lower ends of the inner rail 3, guide rails 4, 4 facing the inner surfaces of the guide rails 2, 2 are provided outward. is there. The guide rails 4 are opposed to the arc-shaped or V-shaped guide rails 2 and 2 so as to be concave or V-shaped. The outer rail 1 and the inner rail 3 can be slid smoothly with the ball 6 held by the ball holding metal 5 interposed therebetween.

[0007] Reference numeral 7 denotes guide rail portions 4 and 4 of the inner rail 3 provided on the inner surface inward from the end of the outer rail 1.
The lock member 7 resiliently presses the inner surface of the inner rail 3. The lock member 7 is attached to the upper and lower ends of the attachment plate portion 8 attached to the main body 1 a of the outer rail 1 by bending the band plates 9, 9. Angle lock portion 9 for resiliently pressing the inner surfaces of guide rail portions 4 and 4
a and 9a are formed of a spring steel plate. 10, 1
Reference numeral 0 denotes a slit provided on the base end side of the mounting plate 8 and the band plates 9, 9 for applying the elastic force of the mountain-shaped locks 9a, 9a. In addition, the lock member 7 may be one in which the mounting plate portion 8 is vertically divided into two at the center. Reference numeral 11 denotes a stopper piece which is bent inward at the end of the outer rail 1, and which comes into contact with the end surfaces of the guide rails 4 and 4 of the inner rail 3 to stop the inner rail 3 at the storage position.

[0007] In this construction, two outer rails 1 are used as fixed side rails and opposed to the side surfaces of a drawer on the main body side of a rack, a cabinet, a desk, or the like, or a side surface of a storage unit such as a slide shelf. The inner rail 3 is attached to both sides of a drawer, a slide shelf or the like, and the inner rail 3 is slid to the outer rail 1 to draw out or store the drawer, the slide shelf or the like.

According to the present invention, the guide rail portions 4, 4 of the inner rail 3 are provided on the inner surface of the outer rail 1 on the inner side from the end.
Is provided with a lock member 7 for resiliently pressing the inner surface of
When the end of the inner rail 3 reaches the end of the outer rail 1 when storing the drawn drawer, slide shelf, or the like, the end surfaces of the guide rails 4, 4 correspond to the chevron lock portions 9 a, 9 a of the lock member 7. The inner surfaces of the guide rails 4 and 4 are resiliently pressed by the mountain-shaped lock portions 9a and 9a of the lock member 7 by depressing the slope, and the speed is reduced to reach the storage position.

Therefore, the drawer or the like decelerates and reaches the storage position, so that no impact is applied between the drawer and the main body such as a cabinet or the like, thereby generating an unpleasant sound or adversely affecting the object stored in the drawer or the like. There is no fear. In addition, the inner rail 3 is maintained at the storage position under the resilient pressing of the lock members 7 on the inner surfaces of the guide rail portions 4, 4.
In a rack, cabinet, or the like in which a plurality of drawers are installed, there is no possibility that the drawers will come out even if a strong shock is applied to the racks.

The lock member 7 may not be made of a spring steel plate but may be made of a plastic material having a spring property. The elastic force may be imparted by interposing a pressing spring between the two mountain-shaped lock portions 9a, 9a without providing the mountain-shaped lock portions 9a, 9a themselves with a spring property.

[0011]

As described above, according to the present invention, a lock member for resiliently pressing the inner surface of the guide rail portion of the inner rail is provided on the inner surface closer to the end of the outer rail. When storing in a rack, cabinet, or other main body, the drawer, etc. is decelerated by the lock member and moved to the storage position, so that no shock is applied to the rack, cabinet, or other main body, and unpleasant noise is generated. Or
There is no danger of adversely affecting the items stored in the drawer or the like. Also, since the inner rail is always kept in the storage position under the elastic pressing of the lock member, the inner surface of the guide rail portion is used in racks, cabinets and the like in which a plurality of drawers and the like are installed,
Even if a strong shock is applied to the rack or the like, there is no danger that the rack will come off. Therefore, the present invention provides a slide rail lock mechanism that solves the conventional problems, and is extremely useful.
