Abstract

PROBLEM TO BE SOLVED: To enable furniture to be easily moved and set in a stable condition, by providing the furniture main body and casters rotatably equipped to the lower edge of the main body in a way capable of setting in/out in the vertical direction. SOLUTION: The vertical position relation between a caster attaching member 4 and the wheel of a caster 3 can be changed by matching a male screw to a screw hole and rotating a cross-slot screw driver D inserted into a cross recess on a shaft through an opening on a flat plate. The caster attaching member 4 is firmly fixed on the inner wall face of a base 2 by a screw etc. Thus, when the position relation between the caster attaching member 4 and the caster 3 is changed, the wheel moves within a range to a position where the wheel protrudes downward from the lower edge 2a of the base 2. At that time, the amount of wheel to set in/out can be arbitrarily controlled by regulating the amount of rotating the driver D. Thereby moving work is enabled to be carried out easily.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to furniture such as closets, bookshelves, and cabinets.

[0002]

2. Description of the Related Art Conventionally, this kind of furniture is usually installed at a predetermined position in a room, and is manually lifted or pushed when moving such as moving or rearranging. In recent years, at the time of building a house, a large room having a large living space is created, and the living space can be divided into a desired size by using this kind of furniture instead of a partition of the large room. Is being done. In such a house, the size of the living space is adjusted by moving furniture as needed.

[0003]

According to the above-mentioned conventional furniture, since the furniture itself is heavy and the weight of the stored items is added thereto, it is difficult to move the furniture, and a large number of hands and large power are required. There was a problem of needing. In particular, as described above, when furniture is used in place of a large room partition, furniture must be moved in order to change the size of the living space, and this difficulty in moving furniture is significant. Burdensome.

[0004] The present invention has been made to solve the above-mentioned problems, and has as its object to provide a furniture which can be easily moved and installed in a stable state.

[0005]

According to a first aspect of the present invention, there is provided a furniture main body, and a caster rotatably attached to the furniture main body so as to protrude and retract from a lower end edge thereof.

[0006] According to this furniture, the caster is attached to the furniture main body so as to be able to roll freely and to protrude and retract from the lower end edge of the furniture main body. The furniture can be moved while rolling the casters on the floor surface by protruding below the lower edge of the furniture. Thus, the furniture can be easily moved, requiring only a light force when the furniture is moved. In addition, when installing furniture after moving, by retracting the caster above the lower edge of the furniture body,
Since the lower end edge of the furniture main body is in contact with the floor, the furniture can be installed in a stable state. Further, when the caster is retracted inside the furniture body, the caster is not visible from the outside, and the appearance is improved.

In the above, the caster is provided with a shaft extending vertically and having an external thread formed on the outer periphery and having a head capable of engaging with a tool, and a wheel rotatably provided at the lower end of the shaft. In addition, it is preferable that a caster mounting member having a screw hole formed in a lower end portion of the fixture main body, into which a male screw of the shaft can be screwed and vertically penetrated is provided.

According to this furniture, a male screw is formed on the outer periphery of the caster shaft, and a screw hole into which the male screw can be screwed is provided.
Since it is formed on the caster mounting member, the caster shaft is screwed into the caster mounting member, and a tool is engaged with the head of the shaft and turned, for example, by inserting a cross driver into a cross hole in the head and turning. The vertical positional relationship between the caster mounting member and the wheels of the caster can be easily adjusted. Further, since the weight of the furniture can be supported by the screwing of the male screw and the female screw, the protruding state of the caster can be reliably maintained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
A fixture according to an embodiment of the present invention will be described. FIG.
2 shows a closet 1 to which the furniture of the present invention is applied. Closed as shown in both figures (furniture, furniture body)
At the lower end of 1, a square frame-shaped base (furniture body) 2 is integrally assembled, and metal (for example, light alloy) casters 3 are provided at four corners inside the base 2. Each is provided.

As shown in FIGS. 2 and 3, the caster 3 is mounted on a caster mounting member 4, and includes a shaft 3a and wheels 3b provided below the shaft 3a. The shaft 3a has a head with an external thread 3c formed on the outer circumference and a cross hole 3d formed on the upper surface.
The cross hole 3d is formed at the lower edge 2a of the base 2 as described later.
In order to adjust the amount by which the casters 3 protrude and retract, the tip of the cross driver D can be engaged with the cross hole 3d as shown in FIG. Further, a fork 3e is attached to a lower portion of the shaft 3a so as to be rotatable around a vertical axis with respect to the shaft 3a. This fork 3e
Has two arms 3f, 3f extending in parallel, and a wheel 3b is rotatably supported around a horizontal axis by an axle 3g passed between these arms 3f, 3f. .

The caster mounting member 4 is made of metal (for example, made of light alloy), and has a rectangular flat plate portion 4a,
Side plate portions 4b, 4b extending vertically downward integrally from two adjacent edges of the flat plate portion 4a. A boss 4 extending vertically downward is provided substantially at the center of the lower surface of the flat plate portion 4a.
c is formed integrally. The boss 4c is hollow and has a screw hole 4d penetrating from substantially the center of the upper surface of the flat plate portion 4a to the lower end thereof. As shown in FIG. 2, the male screw 3c of the shaft 3a is screwed into the screw hole 4d, and the cross driver D is inserted through the opening of the flat plate portion 4a.
By turning the caster mounting member 4 and the wheels 3b of the caster 3, the vertical positional relationship can be changed by turning the caster mounting member d.

Further, since the caster mounting member 4 has its side plates 4b, 4b firmly fixed to the inner wall surface of the base 2 by screws or the like (not shown), as described above, the caster mounting member 4 When the vertical positional relationship between the casters 3 and the wheels 3b is changed, the wheels 3b
2 moves between a position retracted above the lower end edge 2a of the base 2 (a position shown on the left side in FIG. 2) and a position protruding below the lower end edge 2a of the base 2 (a position shown on the right side in FIG. 2). At this time, by adjusting the amount of turning the driver D, the wheel 3
It is possible to arbitrarily adjust the amount of b that appears and disappears from the lower edge 2a of the base 2.

The operation of moving the closet 1 constructed as described above will be described. At the place where the closet 1 is installed, a drawer (not shown) on the lower side of the closet 1 is pulled out, and an opening (not shown) from which the drawer is drawn out. ), While holding the cross driver D, puts his arms. Next, the tip of the cross driver D is inserted into the cross hole 3d of the caster 3 through the opening of the flat plate portion 4a of the caster mounting member 4, and the wheel 3b is turned in a direction to protrude from the lower edge 2a of the base 2. At this time, if necessary, the corner of the closet 1 is slightly lifted off the floor so that it can be easily turned. After one caster 3 is protruded from the lower edge 2a of the base 2, the remaining three casters 3 are protruded from the lower edge 2a of the base 2 by the same operation. After the four casters 3 have all protruded from the lower edge 2a of the base 2, the closet 1 is moved to a desired position while rolling the casters 3 on the floor.

At this time, the caster 3 is fixed to the caster mounting member 4 by screwing the male screw 3c of the shaft 3a and the screw hole 4d of the boss 4c. We can maintain state. Also, wheels 3b
Is mounted rotatably about a vertical axis with respect to the shaft 3a via the fork 3e, so that the direction can be easily changed during movement. By such rolling of the caster 3,
Since the closet 1 is moved, the closet 1 can be moved easily without requiring a large force or manpower at the time of movement, as compared with the case where the closet 1 is lifted or pushed as in the conventional case. Therefore, when this closet 1 is used as a substitute for a large room partition, the operation of adjusting the size of the living space by moving becomes easier than in the past.

Next, when the closet 1 is moved to a desired position, the shaft 3a of the caster 3 is moved in a direction in which the wheel 3b is retracted from the lower end edge 2a of the base 2 by using the cross driver D in the opposite manner. Turn to. Four casters 3 are mounted on two
The lower end edge 2a of the table 2 comes into contact with the floor by retracting from the lower end edge 2a of the base 2. Thereby, the closet 1 is installed in a stable state. At this time, the caster 3 retreats into the table 2 and becomes invisible from the outside, so that the appearance is improved.

In the above-described embodiment, the cross hole 3d is provided at the head of the shaft 3a of the caster 3. However, the present invention is not limited to this, and the head of the shaft 3a may be similar to a hexagon socket head bolt or a hexagon bolt. Any shape can be used as long as it can be turned using a tool. In addition, as an example of the furniture, the one applied to the closet has been described. However, the invention is not limited thereto, and any furniture such as a bookshelf, a cabinet, and a cupboard may be used.
