BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a furniture moving device according to the present invention. In the figure, F is general furniture such as a chest, a bookcase, a cupboard, or a filing cabinet for an office, and the size, use, and shape of the furniture F are not limited. A base B having a required height surrounding the lower part of the furniture is integrally provided below the furniture F. The base B may be manufactured separately from the furniture and may be integrated with the furniture, but may also be manufactured integrally with the furniture.

A furniture moving apparatus according to the present invention is provided in a base B of the furniture F as shown in FIGS. This furniture moving device comprises an upper base 1 which is firmly fixed in a base by screws or the like at the lower bottom surface of the furniture, is inserted into the upper base 1, and can be slid up and down, that is, can move up and down. A lower base 2 on which the above-mentioned casters 3 are mounted, an operating rotary bolt 4 rotatably mounted on the upper base by an operation from outside the furniture, and a screw of the operating rotary bolt A cam 7 that moves laterally by rotation, and an upper roller 9 that is attached to an upper base that guides the upper surface of the cam.
L, 9R, and lower rollers 8L, 8R vertically opposed to the upper roller and attached to a lower base so as to guide an inclined surface formed below the cam.

The upper base 1 has a size and a shape that can be attached to the left and right ends of the furniture F in the depth direction, and the outer periphery of the flat main body is bent almost vertically so that the upper base 2 is vertically moved.
In other words, the guide piece serves as a reinforcement and also serves as a guide piece for guiding the ascending and descending operation reliably.
That is, when the upper base is fixed to the bottom surface of the furniture along the depth direction, the operation turning bolt 4 is disposed on the side that becomes the front side of the furniture.

The operation turning bolt 4 has a handle insertion hole 4H formed at the outer end side thereof for inserting and locking the tip of the turning handle from the outside of the furniture. A screw screw 4S is engraved and is rotatably supported by a fixture 5 fixed to the upper base 1.

A nut-shaped screw 6 is screwed into the screw 4S of the operation rotation bolt 4, and the screw 6S
Is fixed to one end of the cam 7. The upper surface of the cam 7 is contacted by upper rollers 9L and 9R rotatably supported on support shafts 1S and 1S fixed to the upper base 1, and the cam 7 is vertically opposed to the auxiliary roller, and Lower roller 8 rotatably supported by supporting shafts 2S, 2S protruding from lower base 2.
L, 8R are abutted, and are slidably supported by the upper and lower rollers in the lateral direction, that is, along the longitudinal direction of the upper base 1.

The upper surface of the cam 7 may be flat, but the lower surface of the cam 7 is partially formed with inclined surfaces 71 and 72, and the lower rollers 8L and 8L are brought into contact with the inclined surfaces 71 and 72.
When the cam 7 slides through the screw body 6 by the rotation of the bolt 4, the lower rollers 8L and 8R are provided.
With R, a pushing force acts on the cam along the inclined surfaces 71, 72 of the cam, whereby the upper base 1 and the whole furniture F to which the upper base 1 is fixed are pushed up via the upper roller.

When the moved cam 7 is returned to its original position by turning the operation turning bolt, that is, after the furniture is moved to a predetermined position and then re-installed, the bolt may be turned in the opposite direction. . At this time, a tension spring S3 is stretched between a pin P1 protruding from the cam and a pin P2 protruding from the lower base 2 so as to penetrate the long hole 7H of the cam so that the bolt can be rotated more smoothly. It may be set up.

Further, a tension spring S is provided between the upper and lower bases 1 and 2.
1 and S2 are stretched, and thereby a force is applied so that the upper and lower stands always contact each other.

Casters 3 and 3 are attached to both ends of the lower base 2, which penetrates the mounting shaft 3S of the casters 3 to the lower base 2 and is fixed by nuts 3B. However, when the caster is mounted, the outer peripheral surface of the wheel 3W of the caster is prevented from contacting the floor surface at the position where the lower base 2 is hardened. When the upper base 1 is pushed up by the cam, the wheel 3W is set on the floor.

The furniture moving device constructed as described above is mounted inside the base B and on the lower surfaces of the left and right ends of the furniture F. A turning handle or the like is provided on the base B at a position facing the end surface of the operation turning bolt 4. A hole H for insertion is formed. The turning handle has a T-shape, a crank shape, or a shape that can be easily turned with a small torque, and one end of the turning handle is inserted and locked into the handle fitting hole 4H of the bolt 4.

Accordingly, the handle locking hole 4H is formed in a shape such that the tip of the handle is locked in all or a part of the hole and torque is transmitted, for example, a polygonal hole such as a square or a hexagon. This turning handle (not shown) may be made manually or electrically, for example, by using an electric drill.

[0018]

According to the furniture moving device of the present invention, the operation pivoting bolt attached to the furniture is rotated by an operating tool such as a handle inserted from the front side of the furniture, and the cam is moved to move the two cams. The lower base with the casters is lowered by sliding it to the upper base fixed to the lower surface of the furniture base, so that the furniture is lifted, so without taking out any items stored in the furniture, Can be operated lightly. In particular, an upper roller rotatably supported by two support shafts located between two casters and fixed to an upper base that guides the upper surface of the cam with a space therebetween, and opposing the upper roller. In addition, a lower roller rotatably supported by two support shafts fixed at an interval on a lower base for guiding two inclined surfaces formed at a lower portion of the cam is provided. The lower base to which the casters are attached can be stably slid with respect to the upper base fixed to the lower surface of the furniture base.
