Description

[Detailed Description of the Invention] The present invention relates to a drawer opening/closing device using a slider, which allows the slider to be installed easily and reliably, and allows the drawer to be opened and closed smoothly.

Next, to explain the details with reference to the drawings, in Fig. 1, 1 is a drawer side plate, 1' is a protruding part that also serves as a rail provided on the side plate, and 2 is a synthetic resin part attached to the rear end of the protruding part 1'. As shown in FIGS. 2 and 3, the slide 2 is approximately rectangular and has upper and lower sliding surfaces 3 and 4, respectively, and the front part of the inner surface has a hook-shaped part that protrudes forward. It has a locking projection 5 and a pin engaging hole 6 connected to the rear thereof, and a locking projection 8 having upper and lower engaging grooves 7, 7' is provided at the rear.

At the front of the slider, the base of the front locking protrusion 5 is locked inside the front edge of the long hole 9 (Fig. 1) formed in the protruding strip 1' of the drawer side plate, and the long A locking pin 10 fitted into the pin engaging hole 6 is fitted into the rear end of the hole 9 to prevent the slider 2 from retreating.

This locking pin 10 is fixed to the slider 2 by a head 10' and a locking protrusion 10'' that locks inside the edge of the elongated hole 9.

(Figure 4). The locking protrusion 10'' passes through the retaining hole 6 by expanding the band-shaped part 6b (Fig. 2) formed by the slits 6a provided above and below the engagement hole 6, and after passing through, the band-shaped part 6b becomes elastic. It returns to its original position and is locked by this.

In addition, at the rear part, the engagement groove 7.7' of the rear locking projection 8 is
are engaged with and held by the upper and lower edges of a notched groove 11 provided at the rear edge of the side plate convex strip 1'.

Therefore, this slider is connected to the side plate protrusion 1' of the front locking projection 5.
protrudes inward from the elongated hole 9, is moved forward and is engaged with the inner front edge of the elongated hole 9, and the engagement groove 7 of the rear engagement protrusion 8
．． 7' to engage the upper and lower edges of the notched groove 11 on the rear edge of the convex strip,
The locking pin 10 can be reliably attached to the drawer side plate by an extremely simple operation of inserting the locking pin 10 through the pin engaging hole 6 and the elongated hole 9 and fixing it by the locking protrusion 10'' of the pin.

As shown in FIGS. 5 to 7, in this drawer, the slider 2 is fitted between the upper and lower rail plates 13' and 13'' of a fixed rail 13 that has a U-shaped cross section and is fixed to the support wall 12 inside the drawer main body. The side plate protrusions 1' are supported by slides 14 attached to the front end of the lower rail plate 13'', allowing smooth opening and closing.

At that time, a convex portion 15.
16 slidably contacts the inside of the fixed rail 13 to prevent the drawer from swinging laterally.

Also, when the drawer is pulled out, the front end 17 of the slider 2 is stopped by the front locking piece 18 provided on the lower rail plate 13'', and when the drawer is closed, the rear end of the slider 2 is stopped. 19 is locked and stopped by the rear locking piece 20 provided inside the fixed rail 13, so the slide 2 can also serve as a stopper.

The drawer opening/closing device of the present invention has the structure as described above, and has a U-shaped cross section in which the slide 2 attached to the rear end of the convex strip 1' of the drawer side plate 1 is fixed to the support wall 12 of the drawer container body. It is slidably fitted onto the shaped fixed rail 13, and the protruding strip 1' of the drawer side plate is slidably supported by the slider 14 attached to the front end of the lower rail plate 13'' of the fixed rail 13. The drawer can be smoothly opened and closed by the rear slider 2 and the front slider 14, and since the rear slider 2 is slidably fitted to the fixed rail 13 having a U-shaped cross section as described above, the drawer can be opened and closed smoothly. Even if the drawer is pulled out and weight is applied to the front part, the upper rail plate 13 of the fixed rail suppresses upward rotation of the rear part of the drawer, so that the drawer does not tilt forward and can reliably maintain a horizontal state.

Furthermore, locking pieces 18 and 20 are provided protruding from the front and rear sides of the fixed rail 13 to lock the front and rear surfaces 17 and 19 of the rear slider 2 when the drawer is opened and closed. As mentioned above, it can also serve as a stopper when opening and closing the drawer, and in this case, as mentioned above, the rear slider 2 is connected to the front and rear locking protrusions 5 and 8.
It is firmly attached to the convex strip 1' of the drawer side plate, and is prevented from retreating by the locking pin 10 that fits into the elongated hole 9, and the forward edge of the elongated hole 9 and the notched groove 11 allows it to move forward of the slider 2. Since the movement of the slider 2 is prevented, the slider 2 will not come off or move due to shocks when opening and closing the drawer, and can fully fulfill its role as a stopper. This has practical effects such as the ability to attach the slider 2 to the strip 1' extremely easily and reliably.
