Description

[Detailed description of the invention] This invention allows when a drawer, equipment, etc. is removed from the main body and then reattached to the main body, the drawer, etc. can be easily attached by the same operation as when removing it. The purpose is to provide a slide device. below,
The present invention will be explained based on the drawings.

In FIG. 1, A indicates the slide device of the present invention, 1 is an outer member, 2 is an inner member, and 3 is a ball retainer.

The outer member 1 has ball guide grooves 11, 11 in the longitudinal direction of the inner surface, which are formed by curving the upper and lower ends of a band-shaped metal plate into an inward arc shape or a V shape.
The upper and lower bending edges 12, 12 have a substantially C-shaped cross section. And the board 13
A rebound prevention member 4 is attached to the rear inner surface, a guide member 5 is attached to the inner surface, and a retainer spring 6 is attached to the front inner surface. In addition, in front of the retainer spring 6, at a slightly rear position of the guide member 5 and a base plate 13 at the front part of the anti-rebound member 4.
A portion of the retainer is slightly protruded inward to form a retainer front end stopper 14 and a retainer rear end stopper 15. 17 is a hole for attaching the outer member 1 to a furniture body or the like. The vertical length of the front end portion of the outer member 1 is slightly shortened to prevent the inner member 2, which will be described later, from accidentally slipping out. The inner member 2 is approximately the same length as the outer member 1, is made of a band-shaped metal plate, is large enough to be inserted into the outer member 1, and is formed with upper and lower ends curved outward in an arc shape or a V shape. upper and lower bent edges 22, 22 having ball guide grooves 21, 21 in the longitudinal direction of the outer surface;
The substrate 23 is formed into a substantially C-shaped cross section, with the rear end slightly tapered. 24... are mounting holes for drawers, equipment, etc. Ball retainer 3 is
A band-shaped metal plate of a size that can be inserted between the outer member 1 and the inner member 2, and
The length of the outer member 1 is less than half of the length of the outer member 1, and the substrate 31 is rotatably held with balls 33 projecting upward and downward at several locations in the longitudinal direction of both the upper and lower bending edges 32, 32. It protrudes toward the inner member 2 side. In addition, in the drawing, the upper and lower bent edges 32, 32 of the ball holding strip 3 are connected in the front and back, but in order to reduce the weight, the part other than the part that holds the ball 33 is cut off. Good too. The anti-rebound member 4 is made of a plate spring material and includes inner member holding parts 41, 41 formed in a spiral shape at the upper and lower ends on the inner member 2 side, and a guiding slope in which the front and rear ends of the holding parts 41, 41 are tapered. Part 42... and base part 43
The base portion 43 includes mounting holes 44, 44 formed in correspondence with the mounting holes 19, 19 formed at the rear end of the outer member 1. and,
The diameter of the inner member holding parts 41, 41 is the guide groove 1 of the outer member 1 and inner member 2.
1..., 21..., and is formed so as to hold the inner member 2 by the elastic force of the holding part 41 when the rear part of the inner member 2 is located at the rear part of the outer member 1. It is installed at B.

The guide member 5 has both ends bent toward the ball retainer 3 side to form upper and lower edges 51, 51, throttle holes 52, 52 are formed in the upper and lower edges 51, 51, and resin balls 53, 52 are formed in the throttle holes 52, 52. 53 is projected and held on both upper and lower sides, and the base 54 includes:
A positioning protrusion 17' that protrudes a part of the substrate 13 of the outer member 1 to the inner surface, and a mounting hole 18,1
8, position cut holes 55, mounting holes 56, 56
is formed and attached to the inner surface of the front end of the outer member 1 with rivets B. and,
The guide member 5 and the balls 53, 53 are connected to the upper and lower bent edges 12, 12 of the outer member 1 when the inner member 2 is inserted into the outer member 1.
It is determined to have a dimension located between the upper and lower bending edges 22, 22 of the inner member 2. The retainer spring 6 has a vertical movement regulating piece 61 formed by cutting out the central part and folding the upper and lower pieces toward the ball retainer 3 side, and mounting parts 62, 62 formed in connection with the vertical movement regulating piece 61... and the mounting portion 62,
62 is made of a plate spring material bent toward the ball retainer 3 side, and the outer member 1
At least one end portion is movably attached between retainer attachment portions 18', 18', which are formed by cutting a portion of the substrate 13 inwardly and facing each other.

The present invention has the above-mentioned configuration, in which the rear ends of both members 1 and 2 are aligned, the rear end of the ball retainer 3 is in contact with the retainer rear end stopper 15 of the outer member 1, and the anti-rebound member 4 is in contact with the inner member 2. When pulling out a drawer etc. from a state where the rear end is held, first, the rebound prevention member 4
When the ball retainer 3 is pulled out with some force against the elastic force of the inner member 2, the rear part of the inner member 2 is moved away from the anti-rebound member 4, and the ball retainer 3 is continued to be pulled forward. Then, the inner surface of the base plate 31 of the ball retainer 3 moves forward while coming into contact with the curved portion of the retainer spring 6. Therefore, since at least one end of the retainer spring 6 is movable back and forth, the retainer spring 6 is deformed to become flat against elasticity, and is always applied to the inner surface of the ball retainer 3 with a constant force. There will be contact. And further inner member 2
If the drawer (such as a drawer) is continued to be pulled, the front end of the ball retainer 3 will come into contact with the retainer front end stopper 14 of the outer member 1, and the ball retainer will stop. In this state, the outer shape of the front part of the outer member 1 is slightly smaller, so the balls 3 are inserted into the ball guide grooves 11, 11 of the outer member 1 and the ball guide grooves 21, 21 of the inner member 2.
3 is in close contact with the inner member 2, and the ball 33
Stops due to friction. Normally, the contents of the drawer etc. are taken out or equipment is inspected in this state, but if the drawer needs to be moved or equipment needs to be removed for repair, if the drawer etc. is pulled out more forcefully, the ball may The inner member 2 moves forward against the frictional force with the inner member 33 and is pulled out.
In this state, the ball retainer 3 is held in front of the outer member by the elastic force of the retainer spring 6, so that it will not move rearward due to tilting, vibration, etc. of the main body. In other words,
When installing the extracted drawer etc. to the outer member 1 again, from the front end of the inner member 1,
Since the distance to the ball retainer 3 is minimized, attachment of the inner member 2 is easy.

In this embodiment, the slide device such as a drawer is composed of one outer member and one inner member, but when using a combination of several slide devices, the inner member to which the drawer etc. is attached and the inner member can be slid freely. It goes without saying that the present invention can be used for the outer member that has been used.

As described above, in the present invention, one end of the retainer spring made of an elastic material curved toward the ball retainer is attached to the inner surface of the outer member so as to be movable back and forth, so that the retainer spring is easily deformed. It does not hinder movement, and when the inner member is pulled out from the outer member, the ball retainer is held at the front end of the outer member, so when it is time to reattach the inner member, it can be done very easily. This is a useful idea.
