BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mirror plate angle adjusting mechanism capable of adjusting a mounting angle of a so-called mirror plate disposed on a front side of a drawer assembled from a plurality of parts.

[0002]

2. Description of the Related Art Conventionally, in addition to an integrally manufactured drawer,
As a drawer using a metal material such as aluminum, it is known to assemble the drawer by a plurality of parts. In such a drawer, as shown in FIG. 3, the left and right side plates b, b, which are integral with the rail a, and the rear plate c are fixed by screws e, ... It is assembled by fixing the front ends of the side plates b, b and the end plate f with screws g. However, since there is a problem in connection strength between the respective parts only with such an assembly structure, a guard bar h as a reinforcing member is erected by being screwed between the two mounting brackets d, d by using screws i. Furthermore, after inserting the drawer into the furniture body,
In order to correct the fitting condition of the end plate to the furniture, a end plate mounting angle adjuster j capable of adjusting the mounting angle of the end plate is also provided.

As the above-mentioned end plate mounting angle adjusting mechanism, the one shown in FIG. 4 is known. That is,
It has an insert bush k, which is embedded by being driven into the inner surface of the drawer end plate f, and a hook portion m which is hooked so as to be inserted and rotatable in an oblique direction with respect to the mounting hole l thereof, and The rear end is composed of a guard bar o having an axially long screw hole n, and a screw rod q fixed to the rear plate c with a screw p and screwed into the screw hole n of the guard bar o.

[0004]

In the case of the above-mentioned end plate mounting angle adjusting mechanism, the guard bar o itself is rotated to adjust the screwing amount of this and the screw rod q fixed to the rear plate c.
As a result, the mounting angle of the end plate f can be adjusted. However, since the guard bar o is quite long, it is not easy to rotate it with one hand, and both hands must be used, or the base of the screw rod q serves as the adjustment allowance r. The adjustment margin r is exposed and the appearance is not good. Therefore, as shown by the chain double-dashed line in the figure, a structure is added such as covering the adjustment margin r with a separately prepared cover s, and there is no loosening prevention means for the guard bar o and the screw rod q. Therefore, not only is the guard bar o loosely rotated by vibration or the like during drawing and drawing, and the mounting angle of the end plate f is apt to be unintentionally deviated, but a known guard bar o is also provided between the pair of long guard bars o. As described above, a partition member (not shown) is laid over, and as a result, there is a problem that the rotation operation of the guard bar becomes more difficult to perform due to sliding with the partition member.

The present invention has been made in view of the above drawbacks of the above-described conventional apparatus, and the mounting angle of the end plate can be easily adjusted with good operability even when the partition member is mounted. At the same time, it is possible to lock the end plate to the adjustment angle so as not to cause an error, and also to provide a drawer end plate angle adjusting mechanism that is excellent in appearance by not seeing the screw part and the like. That is the purpose.

[0006]

In order to achieve the above object, the drawer end plate mounting angle adjusting mechanism of the present invention has a male threaded portion at the front end that is long in the axial direction, and has a drawer component at the rear end. A guard bar that has a mounting part that can be fixed non-rotatably by being fitted into the groove of a mounting bracket, and the mounting hole of an insert bush embedded in the inner surface of the end plate, is slidably inserted and locked so that it can rotate. An adjuster screw having a hook portion protruding from the front end, and a screw hole screwed into the male screw portion of the guard bar so as to be movable in the axial direction is engraved in the length direction of the rear end, and the adjuster in the male screw portion. A lock nut that is screwed into the male thread so that the screw can be tightened in the axial direction is provided, and the end plate is attached by rotating the adjuster screw. The degree adjustment, there is provided a panel mounting angle adjusting mechanism of the drawer made as may perform s husband tightening the by rotational operation of the lock nut.

[0007]

[Function] The guard bar is tilted forward to the mounting hole of the insert bush which is buried in the inner surface of the end plate in advance, and the hooking portion thereof is obliquely inserted, and then pivoted in a horizontal state to be locked. Fit the mounting part at the rear end of the guard bar into the groove of the mounting bracket and fix it with screws. By doing this, the end plate and the mounting bracket are connected by the guard bar and the adjuster screw that is screwed into this, so by rotating the lock nut and retracting it, it is released from the tightened state with the adjuster screw. The adjuster screw can be rotated.

When the adjuster screw is rotationally operated, the adjuster screw rotates while the hooking part remains hooked on the insert bush, and is screwed with respect to the male screw part of the guard bar to move in the lengthwise direction. Therefore, if the adjuster screw is rotated forward, the end plate tilts forward, and if the adjuster screw is rotated in the opposite direction, the end plate tilts backward. Thus, the end plate is adjusted to any mounting angle.

After adjusting the mounting angle of the end plate, the lock nut is rotated, moved to the adjuster screw side, and the both are axially tightened to lock the adjuster screw, whereby the end plate is adjusted to the pre-adjusted mounting angle. Since the rotation of the adjuster screw is blocked by the lock nut while being fixed, the angle of the end plate is prevented from being deviated due to vibration or the like when the drawer is drawn.
