DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mechanism for attaching a cover for covering a recess formed in a plane and a kotatsu plate.

[0002]

2. Description of the Related Art In recent years, as shown in FIG. 8, there is a type in which a concave portion 2 is provided at one corner of the surface of a kotatsu plate 1 and an operation knob 9 such as a temperature control is provided in the concave portion 2. In particular, a lid for closing the recess 2 was not provided. For this reason, at the time of use, a user's elbow or the like may inadvertently hit the operation knob 9. In addition, when used as a sitting table in summer, the concave portion 2 is completely unnecessary, and is inconvenient to use.

[0003]

For this reason, when the operation knob 9 is not used, it is conceivable to provide the lid 6 for closing the recess 2 by a hinge 10 so as to be freely rotatable. If unevenness such as a knob for opening and closing is formed on the side surface, the unevenness is present on the surface of the kotatsu plate when the lid is attached, which is inconvenient.

In addition to the hinge, it is conceivable to make the lid detachable with a magnet or the like. However, when a magnet or the like is used, a clock, a magnetic recording medium, or the like which will be placed on the operation unit is considered. There is a concern about the adverse effects on

In any of the above cases, when the operation knob is formed in the concave portion, it is assumed that dust or the like is deposited, so that the concave portion is desirably made as shallow as possible.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cover attaching mechanism capable of solving the problems in consideration of such problems as the conventional kotatsu.

[0007]

SUMMARY OF THE INVENTION The present invention provides an apparatus for mounting a lid which satisfies the above-mentioned demands, and has a bottom having a shape fitting into a concave portion formed on a predetermined apparatus surface. It has a dish shape at the top,
Each of the plates has a locking portion at an opposite portion of an inner peripheral edge thereof, and a storage container having an inclined wall formed at an inner peripheral edge different from the inner peripheral edge at which the locking portion is formed, When the lid is attached, the engaging portions provided on both sides of the lid engage with the locking portion of the dish of the storage container, and when the engaged lid comes out, the lid is A slope provided on one rear side of the plate comes out while hitting a slope wall of the dish.

The present invention is also a kotatsu plate, wherein the lid mounting mechanism is provided at a corner.

According to this configuration, there is no need to provide the opening and closing irregularities on the surface of the lid, and the lid is configured to be attached without using a tongue or the like. The size of the recess provided with the operation knob can be reduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below.
A case in which the present invention is applied to an operation knob recess provided in a kotatsu plate will be described with reference to the drawings.

FIG. 1 is an exploded perspective view of a lid mounting mechanism according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a closed state of the lid of the lid mounting mechanism. FIG. 3 is FIG.
AA sectional drawing which shows the principal part of the attachment mechanism of the same lid body of FIG.

In FIG. 1 to FIG. 3, reference numeral 3 denotes a resin storage container having an upper surface formed in the shape of a rectangular dish 30, which is fitted into a concave portion 2 formed in a corner of a kotatsu plate 1. I have. A plurality of control knobs (not shown) are arranged on the bottom surface 30a of the plate 30 of the storage container 3.

Further, projecting locking portions 4, 4 are formed at opposing portions on the inner side surface of the peripheral edge of the plate 30 of the storage container 3. Further, on one of the other inner surfaces different from the opposing locking portions 4, 4, there is formed an inclined wall 5 which is gradually deepened and inclined toward the center of the dish. Further, the inner side surface 50 of the plate 30 facing the inclined wall 5 is not particularly inclined.

Reference numeral 6 denotes a flat lid for covering the plate 30, which has a rectangular shape corresponding to the shape of the rectangular plate 30. Further, a pair of engaging portions 7, 7 that can engage with a pair of locking portions 4 provided on the plate 30 are provided on a pair of left and right opposite sides of the lid 6. That is, the engaging portions 7, 7 are grooves, and the protruding locking portions 4 are fitted into the locking portions 4 so as to be slidable. Further, the groove of the engaging portion 7 is cut out to at least the front portion 61 of the lid 6 (the portion to be put into the plate 30 first) so that the locking portion 4 can be inserted into the groove.

Further, the bottom surface of the front portion 61 of the lid 6 is formed with an inclined surface 8 which is inclined corresponding to the inclined wall 5 of the plate 30.

Next, in this embodiment, the operation of closing the plate 30 of the storage container 3 with the lid 6 will be described.

First, as shown in FIG. 4, the front portion 61 of the lid 6 is slid while being placed on the bottom surface 30a of the plate 30.
As shown in FIG. 5, the front portion 61 of the lid 6 reaches the locking portions 4 and 4. At that time, the locking portions 4, 4 enter the grooves of the engaging portions 7, 7 of the lid 6, and the lid 6 further slides to the back. Then, as shown in FIG.

The upper and lower widths of the groove of the engaging portion 7 and the thickness of the projection of the locking portion 4 are as shown in FIG.
Are designed to have a margin for each other so that they can slide in a slightly oblique state with respect to (see C and C).

In such a state, the lid 6 is fixed to the locking portions 4 and 4.
It does not slip off because it is locked to the plate 30 by. FIG. 3 shows this state.

Next, the operation of removing the lid 6 from the plate 30 will be described.

In the state shown in FIG. 6, the lid 6 is slid to the left in the drawing while pressing the upper surface of the lid 6 with a finger. A slope 8 is formed in the rear part of the lid 6, and a slope wall 5 is formed in the inner peripheral surface behind the plate 30, so that the lid 6 easily changes its direction upward. While sliding out of the plate 30.

Thereafter, the lid 6 smoothly comes out of the plate 30 by the operation opposite to the operation of inserting the lid 6 described above, and
0 is opened. Then, the operation knob on the bottom surface 30a becomes operable.

[0023]

As described above, according to the present invention,
The lid can be detachably attached without providing irregularities on the surface of the lid, and the depth of the dish can be reduced.
