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 main body and may be integrated with the furniture main body, but may be manufactured integrally with the furniture main body.

A furniture moving apparatus A according to the present invention is provided in a base B of the furniture F as shown in FIGS. This furniture moving device is firmly fixed to the bottom of the furniture body on both sides by screws or the like in a base. This moving device is an upper base 1 fixed in a base on a lower bottom surface of the furniture body,
A lower base 2 fitted into the upper base 1 and capable of moving up and down in the vertical direction, and having casters 3 attached to lower surfaces at both ends;
A rotating shaft 4 for operation, which is rotatably mounted in the lower base by an operation from outside the furniture body, and a cam fixed to the rotating shaft for operation and rotated by the rotation of the rotating shaft. 6, 6 are configured to be eccentrically fixed to the axis of the rotation shaft.

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.
That is, it is formed in an elongated box shape having an open lower surface so as to serve as a reinforcing member and a guide piece for guiding the ascending / descending operation reliably, and one end of the upper base 1, that is, the upper base is fixed to the lower surface of the furniture along the depth direction. Then, a hole H for inserting the tip of the handle or the lever into the rotating shaft for operation is formed on the front side of the furniture.

On the lower surface of both ends of the lower base 2, casters 3,
3, which is fixed to the lower base 2 with screws or bolts or the like. This is the same as the conventional caster mounting, but when the caster is mounted, the caster wheel 3W The outer peripheral surface of is not in contact with the floor surface. When the lower base 2 is pushed down by the cam, the wheel 3W is brought into contact with the floor surface, whereby the upper base 1 is substantially lifted.

As shown in FIG. 1, one rotating shaft 4 is inserted into the lower base 2 in the longitudinal direction thereof, and is screwed into the upper base, fixed by welding or the like, and vertically suspended. At least one end face of the rotating shaft 4 faces and is close to the hole H formed in the side end piece of the lower base, and has a square end face. The handle insertion hole 4H is formed such that a polygon such as a hexagon or a part of a circle is missing.

On a rotating shaft 4 rotatably supported by bearings 5 and 5, a position where the upper table 1 is raised on average, for example, as shown in FIG. The cams 6 and 6 having a disc shape or other shapes are fixedly eccentric to the rotation shaft 4 at a predetermined angle, and the cams are rotated together with the rotation shaft. When the short axis side of the cam 6 is on the lower surface, the upper base is in the lowered position, and when the long axis side of the cam is on the upper side, the lower base is pushed down and the casters are grounded according to the eccentric amount of this cam. Act to substantially push up the upper platform.

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

The upper table 1 and the lower table 2 can be slid in the direction of contact with and separated from each other within a range allowed in the vertical direction, but the two tables 1 and 2 are always integrated. They are connected by a telescopic support 9. The support 9 is provided with a single rotating shaft in the longitudinal direction of the lower base 2 and at the center position in the width direction thereof, so that it is arranged on both sides of the shaft avoiding the rotating shaft. At the same time, both sides of the upper base should be kept in parallel so that the upper base and lower base always slide in the direction of contact and separation while maintaining the parallelism. The connecting rods 8 are crimped on one side, and a long hole is formed in the side piece of the lower base in the vertical direction, and the connecting rod 8 is inserted into the long hole.

When the cam 6 has a sector shape or a shape in which at least the surface directly in contact with the lower surface of the upper base makes at least surface contact, the rotation of the cam 6 causes the outer peripheral surface of the cam to directly contact the lower surface of the upper base. The lower casters can be grounded by the eccentricity caused by the rotation of the cam so that the upper stand can be substantially lifted. However, when the disc-shaped cam 6 is used as shown in FIG. 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 base. When this cam guide is used, the eccentricity of the cam due to the rotation of the cam makes the contact with the lower stand always surface contact, the pushing force of the lower stand is made uniform, and the lower stand is transmitted smoothly to the lower stand. is there.

A thrust bearing 10 is provided 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 slidable via the thrust bearing 10 to support a load. Thereby, the sliding of the cam guide at the time of cam rotation can be performed smoothly and lightly. 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 base. However, when the furniture is lowered, the cam guide is moved by the load of the furniture. Is also depressed. At this time, as shown in the figure, to help the gum guide return to the horizontal direction,
A spring 11 may be provided between the end surface of the cam guide and the inner surface of the lower base.

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

Accordingly, the handle locking hole 4H is formed in a shape such that the tip end of the handle is locked to all or a part of the hole and a torque is transmitted, for example, a polygonal hole such as a square or a hexagon. This turning handle (not shown) is inserted into the end face of the turning shaft, and the turning angle is set to a predetermined angle, for example, 170-2.
By tilting about 00 degrees, the rotating shaft / cam is rotated to move the upper and lower bases in the vertical direction as described above, that is, the lower base is pushed down to ground the casters, and the furniture is slightly moved through the upper base. It can be lifted and moved by casters.
