Description

Furniture wheel device {Furniture wheel device}

The present invention relates to a wheel device for furniture, and more particularly, to a wheel device for furniture, having a leg coupling means for coupling to the legs of the furniture, and having a braking means for elastically immersed and broken in use. The purpose of the present invention is to provide a braking limiting means for limiting the braking according to the user's choice in use, so that the furniture can be moved smoothly and quietly without noise when the furniture is moved, and a stable fixed state can be maintained during use.

In general, the furniture legs are in close contact with the floor, such as furniture for the table, and the wheels such as casters are provided on the legs so as to be able to push and move while sitting like a chair among office furniture.

As described above, the office furniture provided with casters such as casters on the legs is configured to enable the wheels to be clouded even in a used state, such that the furniture rolls over in an unstable seating process.

Therefore, as disclosed in the Republic of Korea Utility Model Registration No. 0262499, the wheel body is elastically protruded through the spring as a spring, so that the wheel is elastically immersed in use and friction contact with the wheel body housing causes the rolling of the wheel to stop. have.

However, the conventional furniture wheel as described above had a problem that the movement is impossible when the wheel is elastically immersed in use and trying to move in a clouded state.

Thus, the present invention, as described above, the wheel for the furniture configured to stop the movement when the seat is elastically immersed as in the conventional chair wheel is impossible to move in the seated state, and can not be used in response to furniture having a variety of structures This is to improve the problem.

That is, the present invention is a wheel device for furniture, having a leg coupling means for coupling to the legs of the furniture, and having a braking means to be elastically immersed and braked in use, braking is limited according to the user's choice in use It is provided with a braking limiting means.

Therefore, the present invention has a wheel that is coupled to the furniture legs to facilitate the movement of the furniture in the state of using the furniture is limited to the movement of the furniture to maintain a safe fixed state, when using the brake of the wheel according to the needs of the user It can be limited.

That is, the present invention is a furniture wheel apparatus, having a leg coupling means for coupling to the legs of the furniture, having a braking means for the wheel to be broken when in use, and braking of the wheel according to the user's choice when using And braking limiting means for limiting.

Here, the leg coupling means is composed of a tightening fastener 110 is fastened and fastened by fitting to the leg.

As shown in FIGS. 1 to 3, the tightening fastener 110 has tightening restraints 112 for tightening and restraining the legs by equally spaced cutting grooves in the longitudinal direction and the tightening restraining unit 112 side. It is composed of a tightening nut 111 is screwed to the tightening screw 113 formed in the tightening constraining portion 112 is contracted in the radial direction to tighten the operation.

The tightening constraining part 112 is formed such that its outer diameter becomes narrower from the inner side to the outer side, and the tightening nut 111 has an outer side inner diameter which is formed larger than the outermost part of the tightening constraining part and smaller than the central part. In the fastening process is configured to tighten the tightening restraint unit 112.

Meanwhile, as shown in FIG. 5, the tightening constraining part 112 may be provided with an adapter bush 114 having a cylindrical shape so as to absorb and insert an internal diameter variation according to the size and shape of the furniture leg. .

The adapter bush 114 is made of elastic rubber, and the inner side is formed of a circular or polygonal hole according to the outer shape of the furniture leg.

And, another embodiment of the leg coupling means is composed of a leg binding bolt 120 is screwed to the furniture leg as shown in Figure 6 and 7.

In addition, the braking means is formed in a semi-circular shape, as shown in Figure 3, the wheel housing 200 is provided with a leg coupling means at the top, and the wheel shaft portion is coupled to the wheel protruding downward from the wheel housing 200 (210), the wheel lifting hole 211 formed to form a long hole up and down on the wheel shaft portion 210, and the wheel (1) is elastically immersed by the weighted load when used on the inner surface of the wheel housing 200 It is composed of a wheel spring 220 which is brought into frictional contact with the formed friction part 201 and elastically protruded and rolled when the load is removed.

On the other hand, the braking limiting means is provided with a support rod 310 protruding upward by supporting the wheel spring 220 on the upper portion of the braking means, as shown in Figures 1 to 4, the upper side of the support rod 310 The braking limiting cam 320 is pivotally coupled to an upper portion of the wheel housing 200 to limit the protrusion of the support rod.

It is provided rotatably on top of the wheel housing 200 of the braking limiting cam 320, the handle 321 is configured to protrude to the front side.

Hereinafter, described in detail by the accompanying drawings as follows.

As described above, in the furniture wheel device, having a leg coupling means for coupling to the legs of the furniture, and having a braking means for the wheel to be broken when in use, the braking of the wheel according to the user's choice when using It is provided with a braking limiting means to be limited, wherein the leg coupling means is composed of a tightening fastener 110 is fastened and fastened by fitting to the leg,

The braking means is a wheel lifting hole 211 formed to form a long hole up and down on the wheel shaft portion 210 of the wheel housing 200, and the wheel 1 is elastically immersed by the weighted load of the wheel housing 200 It consists of a wheel spring 220 which is brought into frictional contact with the friction portion 201 formed on the inner surface of the inner surface, and elastically protrudes and rolls when the applied load is removed.

The braking limiting means includes a support rod 310 protruding upward by supporting the wheel spring 220, and is pivoted on the top of the wheel housing 200 to limit the protrusion of the support rod on the upper side of the support rod 310. When using the furniture implemented by applying the present invention having the bound braking limiting cam 320, the wheel 1 is elastically immersed in friction contact with the friction portion 201 of the wheel housing 200, the cloud is limited It is to maintain a stable fixed state.

On the other hand, in the practice of applying the present invention, if the braking is to be limited when the braking limiting cam 320, which is a braking limiting means as shown in Figure 4 by the braking limiting cam 320 The support rod 310 is lowered to limit the amount of elastic immersion of the wheel 1 so that the wheel 1 does not come into contact with the friction part 201 of the wheel housing 200, so that the braking action is not performed and the furniture is not used. Clouds can be moved.
