When assembling the drawer supporting device B of the present invention, first, as shown in FIG.
While fitting the front rail receiving member 7 in a slightly inclined state, the compatible walls 18 and 18 having a substantially U-shaped cross section are fitted to the protrusions 13 of the front reinforcement 5 fixed to the lower surface, and the rear standing wall 18 Nail piece 19
Are engaged with the engaging holes 14 of the ridges 13, and the front standing wall 18
The projecting piece 20 is pushed into the opening 15, and the claw piece 21 of the projecting piece 20 is locked to the rear edge of the opening 15 to be fitted and locked substantially horizontally. Next, as shown in FIG. 8, a slider 32, which is attached rearward to a support plate 34 of the rear connecting member 11 fixed between the rear portions of both side rails 9, 9, is provided with a concave groove formed in the front opening of the rear rail receiving member 8.
The slider 32 fitted forward to the connecting plate 33 of the front connecting member 10 fixed between the front portions of the both side rails 9 in the state of being fitted in the inside of 26 so as to be slidable laterally is fitted to the front reinforcing member 5. The rear rail receiving member 7 is fitted in the recessed groove 22 opened rearward so as to be slidable in the lateral direction, and the compatible walls 23, 23 of the rear rail receiving member 8 having a substantially U-shaped cross section are provided on the ridge 16 of the rear reinforcing member 6. Claw plate formed by the rear standing wall 23 by fitting the claw piece 24 projecting from the front standing wall 23 into the engaging hole 17 formed in the front side surface of the projection 16 while being fitted from below. The state where 25 is pressed against the rear side surface of the ridge 16 is completed, and the assembly is completed as shown in FIG. The drawer C is supported by the well-known slide mechanism so that the drawer C can be drawn back and forth on both side rails 9 and 9 supported by the front rail receiving member 7 and the rear rail receiving member 8 mounted on the lower surface of the top plate A so as to be slidable in the lateral direction. To do.

In this manner, the sliders 32 of the front connecting member 10 and the rear connecting member 11 are slid laterally in the concave groove 22 of the front rail receiving member 7 and the concave groove 26 of the rear rail receiving member 8, respectively, to thereby draw out the drawer C. After being freely moved in the lateral direction and set to a desired position, it can be pulled out in the front-rear direction.

[Effect of device]

According to the drawer support device of the present invention as described above, the drawer can be supported so that it can be drawn out forward and backward and can be slid laterally, and in the assembly thereof, the front reinforcement projection fixed to the lower surface of the top plate. The standing wall of the front rail receiving member is fitted into the strip from below, and the claw pieces projecting from the standing wall are engaged with the engaging holes formed on the front side and / or the rear side of the projecting strip, and the rear connecting member is formed. In the state in which the slider mounted rearwardly on the front rail member is fitted slidably in the recessed groove formed in the front of the rear rail receiving member, the slider forward mounted on the front connecting member is fitted and locked to the front reinforcement. The rail receiving member is laterally slidably fitted in the recessed groove that is opened rearward, and the standing wall of the rear rail receiving member is fitted to the rear reinforcing projection from below, and the front side and / or rear of the projection is provided. Projected on the standing wall in the engaging hole formed on the side It is possible to assemble very easily and in a short time by a fitting work that only engages and installs the claw pieces, and in the assembled state, the front rail receiving member and the rear rail receiving member are front reinforcing and rear While the claw pieces that are externally fitted to the respective ridges of the reinforcement and are provided on the standing wall engage with the engaging holes formed on the front surface and / or the rear surface of the ridge,
Further, since the front and rear connecting members fixed to the front and rear portions of the both side rails are fitted in the facing concave portions of the front and rear rail receiving members, respectively, the sliders which are attached so as to project forward and backward respectively, are fitted in abutting state. The receiving member does not come loose and fall out, and it is extremely strong and has excellent durability. Since the front-rear connecting member can be slid laterally with respect to the front-rear rail receiving member via the slider, an appropriate frictional force can be set between the slider and the groove for guiding the slider. The drawer does not excessively move in the lateral direction, and can be easily moved when it is desired to move it.
