The first side slide rail 12a is moved in the direction of arrow C, so that the first side L-shaped projection portion 212a and the third side L-shaped projection portion 212b are inserted into the first fitting hole 321a and the third fitting hole 321b, respectively. The first side slide rail 12a is moved in the direction of arrow D until the first side L-shaped projection portion 212a and the third side L-shaped projection portion 212b contact the lower end of the first fitting hole 321a and the third fitting hole 321b. The first side slide rail 12a is moved in the direction of arrow F, and the first bulge 212c of the first side L-shaped projection portion 212a and the third bulge 212d of the third side L-shaped projection portion 212b are hooked and fixed at the first cutout 321c of the first fitting hole 321a and the third cutout 321d of the third fitting hole 321b. When the holding force between the first and third bulges 212c, 212d and the first and third cutouts 321c, 321d is lacking, they also may be fixed by clinchers. Also, unit 42 is fixed to the first side slide rail 12a by a clincher 22a and a clincher hole 232a of the first unit-engaging slide member 221a.
As shown in
As described above, according to the slide rail structure of the second embodiment, the side of the first side slide rail 21a that contacts the chassis 32 may include two side L-shaped projection portions created by bending work from the first body portion after U-shaped punches are made, and these side L-shaped projection portions, each with its respective bulge, are arranged in the front side of the chassis 32. The side of the second side slide rail 21b may include the second side L-shaped projection portion 212f which has the second bulge 212h, and the fourth side L-shaped projection portion 212g which has the fourth bulge 212i, as with the first side slide rail 21a. The one side of the chassis 32 may include the first fitting hole 321a which has the first cutout 321c, and the third fitting hole 321b which has the third cutout 321d in the front portion of the side of the chassis 32 to insert and hook the first side L-shaped projection portion 212a and the third side L-shaped projection portion 212b. The other side of the chassis 32 may include the second fitting hole 321f which has the second cutout 321h, and the fourth fitting hole which has the fourth cutout 321i in the front portion of the side of the chassis 32 to insert and hook the second side L-shaped projection portion 212f and the fourth side L-shaped projection portion 212g. Therefore, the first side slide rail 21a can be fixed to the chassis 32 only to insert and hook the first side L-shaped projection portion 212a to the first fitting hole 321a, and the third side L-shaped projection portion 212b to the third fitting hole 321b. And to fix the second side slide rail 12b to the chassis 32 the worker has only to insert and hook the second side L-shaped projection portion 212f to the second fitting hole 321f, and the fourth side L-shaped projection portion 212g to the fourth fitting hole 321g. Therefore, the worker does not need to insert his or her hands into the chassis 32 in order to screw a clincher, and is able to assemble the slide rails easily without dropping the first side slide rail 12a and the second side slide rail 12b while at work.
As described above, the first and third sides L-shaped projection portions 212a, 212b are created by bending work from the first body portion after the punching of the side of the first chassis-engaging slide member 211a. However, as in the first embodiment the side L-shaped projection portions instead may be welded to the side of the first chassis-engaging slide member 211a. Also, while the first side slide rail 12a is described to include the first chassis-engaging slide member 211a, the first unit-engaging slide member 221a and the first intermediate slide member 231a, the first side slide rail 12a may include only the first chassis-engaging slide member 211a and the first unit-engaging slide member 221a.
The slide rail structure of the second embodiment described above, in addition to having the effects of the first embodiment, allows the slide rail to be fixed by the first side slide rail 12a and the second side slide rail 12b moving in only one direction, and the worker is able to work more easily, and can reduce the likelihood that he or she may drop and break the first side slide rail 12a and the second side slide rail 12b while at a work.
The first side slide rail 12a and the second side slide rail 12b can be arranged in the chassis 32 by moving them in one direction. Therefore the first side slide rail 12a and the second side slide rail 12b do not need to enter the back of the chassis 32 to be fixed, and it is possible to make the depth of the chassis 32 smaller.
Other VariationAccording to the above explanation of the first embodiment and the second embodiment, the pair of slide rails each may include two side L-shaped projection portions, and the chassis may include two fitting holes on each side, but the number of them on each side may be more than three or limited to one.
