Description

[Detailed Description of the Invention] <<Industrial Application Field>> The present invention particularly relates to a sliding device for a top plate of a desk or the like.

<<Prior Art and Problems>> The above-mentioned conventional slide device has a movable side rail fixed to the back of the top plate, connected to the top plate of the desk body,
It consists of a fixed side rail that holds the movable side rail slidably in the front and back direction, and the fixed side rail has the left and right ends of the board bent inward into a substantially circular arc,
It has left and right bent edges with ball guide grooves on the inner surface,
The moving side rail has the left and right ends of the board bent outward, and has left and right bent edges with ball guide grooves on the outer surface, and a plurality of steel balls with a predetermined interval between the two bent edges. A ball retainer that rotatably holds the is arranged between both rails, and a front and rear stopper is formed at the front and rear ends of the stationary side rail, and a rear stopper is formed at the rear end of the movable side rail, so that the movable side rail moves forward. When the moving side rail moves backward, the rear stopper of the moving side rail touches the rear end of the ball retainer, the front end of the ball retainer touches the fixed side rail front stopper, and the forward movement stops, and when the moving side rail moves backward, the movement stops. The rear stopper of the side rail came into contact with the rear stopper of the stationary side rail to stop the rearward movement.

For this reason, in order to smoothly slide the stationary side rail and the movable side rail, a high degree of processing accuracy is required in the formation of both bent edges, the size of the steel balls, etc., which has the disadvantage of being expensive.

The purpose of the present invention is to provide a sliding device for a top plate, etc., which has a simple structure that does not require high processing precision, can be manufactured at low cost, and can provide smooth sliding.

<<Example>> Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 3 shows an exploded perspective view of the main parts of a desk equipped with the present invention, in which 1 is the desk body, 2 is a top plate attached to the desk body 1, and 21 is a top plate attached above the rear end of the top plate 2. Desk bookshelf, 3, 3 is desk body 1 and top plate 2
This is a slide device installed at the left and right ends between the two.

The desk body 1 includes a sleeve cabinet 11 having four drawers in the vertical direction, a leg body 12 standing at a predetermined distance from the sleeve cabinet 11, and a
A desk top plate 13 is attached to the top end of the desk and the top surface of the sleeve cabinet 11, a central drawer 14 is formed on the left underside of the desk top plate 13, and a leg 1
A foot rest 15 is provided at the front lower end between the side cabinet 11 and the seat 2, and the lower shelf 16 is provided so as to be freely height adjustable.
It is composed of a rear plate 17 etc.

As shown in FIG. 4, in normal use, the top plate 2 has front, rear, left and right end surfaces that are the front surface of the desk body 1 (the front surface of the front panel of the drawer of the sleeve cabinet 11 and the front panel of the front panel of the center drawer 14); With the palm of the hand pressed against the front end surface of the top plate 2, press the fingertips in the width direction of the lower surface of the front end protruding from the left and right end surfaces of the legs 12 and the sleeve cabinet 11, and the rear end surfaces of the legs 12 and the sleeve cabinet 11. A finger jamming prevention protrusion 21 is formed having a depth dimension that prevents the fingers from slipping into the rear.

Continuing with the left and right ends of the finger jam prevention projection 21, left and right projections 23, 23 are formed in the depth direction of the lower surface of the left and right ends of the top plate 2, and the upper part of the desk body top plate 13 and the top A predetermined space 20 is formed on the lower surface of the plate 2, behind the finger jam prevention ridge 21, and between the left and right ridges 23, 23, in which the rail devices 3, 3 are attached.

Slide device 3 As shown in FIG. 1, FIG. 2, and FIG. It is comprised of a fixed side rail 32 that holds a rail 31 slidably in the front-rear direction and is connected to the desk main body top plate 13.

The fixed side rail 32 has a sliding groove 3 that is open at the top.
21, guide holding grooves 322, 322 formed on the left and right side portions slightly above the sliding groove 321, and mounting protrusions 323, 323 formed on the lower left and right end portions so as to protrude laterally. and the upper surface of the sliding groove 321,
Upper walls 324, 324 of guide holding grooves 322, 322
On the lower surface, there are sliding protrusions 325, 325, 326, 32 for smoothly sliding the moving rail 31.
6 is integrally formed by extrusion of synthetic resin.

The fixed side rail 3 configured as described above comes into contact with the upper wall 324 of the guide holding grooves 322, 322 and the upper surface of the mounting protrusion 323, and is a fixed side rail holding member that is screwed to the desk main body top plate 13. 327,327
, the moving side rail 3 comes into contact with the upper surface of the sliding groove 321.
The end of the 1 side protrudes upward and the front and rear stoppers 3
31, 341 are formed, and are fixed on the desk main body top plate 13 by front and rear stopper members 33, 34 screwed to the desk main body top plate 13.

The moving side rail 31 has the sliding groove 321
Consisting of a sliding groove 311 located above and mounting parts 312, 312 screwed to the back surface of the top plate 2, the central part of the sliding groove 311 and the front and rear ends have side walls 313, which penetrate through the side walls 313. There are provided upward stop portions 314 whose left and right ends are located within the guide holding grooves 322, 322.

316, 317 are the front and rear stopper portions 33;
It is a front and rear stopper formed corresponding to No. 1,341.

The present invention is formed as described above, and from the state shown in Figure 1, the suspension can be used widely, or
When a study assistant is seated alongside the child, or a child who is unable to pull a chair closer to the desk, slide the top plate 2 toward you, and the front stopper 331 will eventually move to the moving side rail. The front stopper 316 collides with the front stopper 31, and the forward movement of the top plate 2 is stopped.

Further, when the top plate 2 is moved to the rearmost position, the rear stopper abutment 317 collides with the rear stopper portion 341 of the rear stopper member 34, and the backward movement of the top plate 2 is stopped.

In addition, 310, 310 is the front and rear stopper part 33
This is a cushioning material provided on the inner surface of 1,341.

《Effect》 As mentioned above, since the fixed side rail has a shape that can be formed by extrusion molding of synthetic resin material, it can be manufactured at low cost, and by forming a sliding protrusion in the sliding groove, it can be made in a shape that can be formed by extrusion molding of synthetic resin material. Smooth sliding can be achieved by extremely reducing the contact area.

Further, since the stopper part is projected outward from the side wall of the sliding part and positioned within the guide holding groove, the top plate does not lift up from the top plate of the desk main body, making it safe.
