DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The furniture moving apparatus of the present invention will be described below with reference to the illustrated embodiments. In the figure, F is general furniture such as a closet, a bookcase, and 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 is provided integrally with the lower part of the furniture F so as to surround the lower part of the furniture. The base B may be manufactured separately from the furniture main body and integrated, but it is also possible to manufacture the base B integrally with the furniture main body.

Inside the base B of the furniture F, the furniture moving apparatus A of the present invention is provided as shown in detail in FIGS. This furniture moving device is firmly fixed to the bottom of the furniture main body on both sides with screws or the like in the base. This moving device is the lower bottom surface of the furniture body, and the upper base 1 fixed in the base,
A lower base 2 which is fitted and inserted in the upper base 1 so that it can be vertically moved up and down, and casters 3 are attached to the lower surfaces of both ends,
A rotating shaft 4 for operation mounted rotatably in the lower table by an operation from the outside of the furniture body, and a cam fixed to the rotating shaft for operation and rotated by rotating the rotating shaft. 6 and 6 are eccentrically attached to the axis of the rotating shaft and fixed.

The upper pedestal 1 has a size and shape that can be attached in the depth direction at both left and right ends of the furniture F, and the outer periphery of a flat plate-like body piece is bent almost vertically to move the upper pedestal 2 in the vertical direction.
In other words, the upper and lower ends of the upper stand 1 are fixed to the lower bottom of the furniture along the depth direction while forming a slender box-like shape with an opening on the lower surface so as to also serve as a guide piece for guiding up and down operations reliably. When this is done, a hole H for inserting the tip of the handle or lever into the rotary shaft for operation is bored on the front side of the furniture.

Casters 3 are provided on the lower surfaces of both ends of the lower base 2.
3 is attached, but this is fixed to the lower base 2 with screws or bolts, which is the same as the conventional caster mounting, but when the caster is mounted, the wheel 3W of the caster is used at the position where the lower base 2 is lowered. The outer peripheral surface of should not touch the floor. Then, when the lower base 2 is pushed down by the cam, the wheel 3W is grounded to the floor surface, so that the upper base 1 is substantially lifted.

Further, as shown in FIG. 1, a single rotating shaft 4 is inserted in the lower base 2 in the longitudinal direction thereof, and a bearing is vertically installed by being fixed to the upper base by screws, welding or the like. 5 and 5 are rotatably supported, and at least one end face of the rotating shaft 4 is made to face and be close to the hole H drilled in the side end piece of the lower stand, and the shaft end face has a square shape. A handle insertion hole 4H is formed such that a polygon such as a hexagon or a part of a circle is cut off.

On the rotary shaft 4 rotatably supported by the bearings 5 and 5, the upper base 1 is raised on average, for example, near both ends of the lower base 2 as shown in FIG. The cams 6 and 6 each having a disk shape or other shape are eccentric to the rotary shaft 4 by a predetermined angle, and the cams 6 and 6 are rotated together with the rotary shaft. When the short axis side of the cam 6 is the lower surface, the upper table has a lowered position load, and when the long axis side of the cam is the upper surface, the lower table is pushed down and the caster is grounded according to the eccentric amount of the cam. The upper base is operated so as to be substantially pushed up.

The eccentricity of the cam 6 is appropriately set so that furniture placed on the floor can float above the floor and can be moved by casters, but it is generally about 10 mm.

Although the upper and lower bases 1 and 2 can slide in the contacting and separating directions with respect to each other within a range allowed in the vertical direction, the two bases 1 and 2 are always integrated. They are connected by a stretchable support 9. Since this support 9 has a single rotating shaft arranged in the longitudinal direction of the lower base 2 and at the center position in the width direction thereof, it is arranged on both sides of the rotating shaft so as to avoid this rotating shaft. Along with both sides of the upper base so that the upper base and the lower base always slide parallel to each other in the contact and separation directions and that the opposing side pieces of the upper base and the lower base do not spread even under load. The connecting rods 8 are crimped between the pieces, and vertical holes are formed in the side pieces of the lower table, and the connecting rods 8 are inserted into the elongated holes.

When the cam 6 is fan-shaped or has a shape such that at least the surface in direct contact with the lower surface of the upper base is in surface contact, the outer peripheral surface of the cam is brought into direct surface contact with the lower surface of the upper base by the rotation of the cam 6. It is also possible to bring the casters of the lower base into contact with each other by eccentricity caused by the rotation of the cam so that the upper base can be substantially lifted up. The cam 6 is rotatably fitted in a circular cam fitting hole 7h formed in the cam guide 7, and the lower surface of the cam guide 7 is brought into contact with the inner bottom surface of the lower table. When this cam guide is used, the eccentricity of the cam due to the rotation of the cam makes the contact with the lower table always in surface contact so that the pressing force of the lower table is made uniform and the lower table can be pushed down smoothly. is there.

A thrust bearing 10 is arranged on the lower surface of the cam guide 7 in the longitudinal direction of the cam guide, and the cam guide and the lower base are slidably supported by the thrust bearing 10 to support the load. As a result, the cam guide can smoothly and smoothly slide when the cam rotates. At this time, the cam guide descends according to the amount of eccentricity due to the rotation of the cam, and also moves in the horizontal direction to push down the lower table, but when lowering the furniture, the load of the furniture causes the cam guide to move. Can also be pushed down. At this time, in order to assist the gum guide to return to the horizontal direction, as shown in the figure,
The spring 11 may be disposed between the end surface of the cam guide and the inner surface of the lower base.

In the furniture moving apparatus constructed as described above, the holes F for inserting one end of the handle or the lever are formed in the base B and at the left and right ends of the furniture F. This handle or lever is L-shaped, crank-shaped,
In addition, the rotating shaft with a cam is formed to be easily rotated by a small torque, and one end of the rotating shaft is inserted and locked in the handle fitting hole 4H of the shaft 4.

Therefore, the handle locking hole 4H has a shape in which the tip of the handle is locked to all or a part thereof so that torque is transmitted, for example, a polygonal hole such as a quadrangle or a hexagon. A handle (not shown) for this rotation is inserted into the end surface of the rotation shaft, and this is adjusted to a predetermined angle, for example, 170-2.
By tilting it about 00 degrees, the rotating shaft / cam is rotated to move vertically between the upper stand and the lower stand as described above, that is, the lower stand is pushed down to ground the casters and the furniture is slightly moved through the upper stand. It is possible to lift and move by casters.
