Description

  The present invention relates to a furniture caster structure, and more particularly to a furniture caster in which the structure of the caster element and its assembly achieve practical effects.

Tables and furniture such as low boards are equipped with casters for convenient movement. In particular, the wooden material is heavy, so that it is easy to move when a caster is attached. Many existing casters are made of metal, have a complicated structure, and the weight of the material is heavy. Many of the existing casters are fixed to the furniture with screws or connecting elements, especially wooden furniture. Then, the beauty of furniture will be damaged.

An object of the present invention is to provide a furniture caster that has a feature that the caster is light and has a simple structure, and has a beautiful appearance when the caster is attached to the furniture.

The present invention uses only a pad and a coupling element, mounts an interlocking seat in the base, sandwiches a plurality of stainless balls between the base and the interlocking seat, and is very easy to mount the ring body. Another object is to provide a furniture caster in which the entire structure of the element is simple and the assembly is quick and simple.

  The furniture caster of the present invention includes a base, an interlocking seat mounted in the base, and at least one ring body pivoted on the interlocking seat.

  Provided is a furniture caster that does not impair the beauty of furniture, is easy to install, and is quick to assemble.

As shown in FIG. 1, the caster applied to the furniture of the present invention includes a base 10, an interlocking seat 20 mounted in the base 10, and at least one ring body 26 pivoted on the interlocking seat 20. The interlocking seat 20 rotates around the entire circumference relative to the base 10, the ring body 26 rotates relative to the interlocking seat 20, smoothly moves the furniture in each direction, and is easy to assemble with simple elements. Is an effective caster.

As shown in FIG. 1 and FIG. 2, the cross section of the base 10 is a gate-shaped circular lid, the outer sealing surface abuts the furniture coupling surface 11, and the center of the inner top surface has a screw hole 121. The protrusion 12 is formed, and the outer ring side of the protrusion 12 is an outer rib 13 of the ring protrusion, and the outer side of the outer rib 13 is an annular concave arc-shaped base basin 14. The element 15 is a plurality of stainless balls.

As shown in FIG. 2 and FIG. 3, the interlocking seat 20 is circular and is accommodated in the base 10, and the interlocking seat 20 forms an annular concave arc-shaped interlocking basin 21 in the end surface direction of the base 10. The pearl tank 14 and the rolling element 15 are sandwiched, and the rolling element 15 is positioned in the space between the interlocking basin tank 21 and the base basin tank 14, and the interlocking seat 20 rolls relative to the base 10. The center of the interlocking seat 20 forms an inner hole 22 corresponding to the protrusion 12, and the outer side of the inner hole 22 forms an annular protruding edge 221, and the protruding edge 221 is placed outside the outer rib 13 of the base 10. On the other hand, the inner hole 22 is constrained by the outer rib 13, and the interlocking basin tank 21 and the base basin tank 14 maintain the clamping state of the rolling element 15, and the screw-like coupling element 25 is connected to the pad 24 The inner hole 22 is pierced and screwed into the screw hole 121, and the pad 24 is stuck on the outer rib 13 to provide the coupling element 25 with a fulcrum action. Further, the pad 24 stops a part of the protruding edges 221 and prevents the interlocking seat 20 from falling off the base 10.

The bottom side of the interlocking seat 20 has two pivot tanks 23 that correspond to each other in a straight line and are provided at both ends of a shaft 261 that pierces the ring body 26 and is fixed in the pivot tank 23. The shaft 261 is rotated as a fulcrum.

2 and 4 show an embodiment of mounting on furniture, and a bottom of the support leg 41 of the furniture 40 is provided with a set of tanks 42 relative to the altitude and outer diameter of the base 10 coupling surface 11. Then, it is closed and fixed to the coupling surface 11 of the base 10, and the ring body 26 supports the furniture 40 and contacts the ground.

Thereby, when the ring body 26 changes direction, the interlocking seat 20 surrounds the rolling element 15 until it is in an appropriate direction, and the furniture 40 is moved in a linear direction by the ring body 26. Since the base 10, the interlocking seat 20, and the ring body 26 of the present invention can be made of a plastic material, they are lightweight, and since the interlocking seat 20 and the base 10 can be assembled with only the coupling element 25, the structure is simple and the assembly is easy. It is easy and practical.

5 and 6 show another embodiment, in which the base 10 is engaged in the engagement seat 30 and assembled in the assembly basin 42 on the bottom side of the furniture support legs 41 having different scales. 10 and the assembly element between the furniture support legs 41, the bottom surface of the engagement seat 30 is recessed in the engagement tank 31, and the engagement tank 31 is closely engaged with and engaged with the base 10. The top surface of the seat 30 projects the ring body 32 upward, and the periphery of the ring body 32 is provided with a plurality of elastic ribs 321 in the radial direction, and the ring body 32 is closely attached to the furniture by the plurality of elastic ribs 321. 40 is assembled in a tank 42 on the bottom side of the support leg 41, the bottom side of the support leg 41 of the furniture 40 is stopped at the position of the top periphery of the engagement seat 30, and the base 10 is furniture of different scales by the engagement seat 30. It is attached in the support leg 41 of the furniture, and the assembly ability of the furniture caster is enhanced.

  In the present invention, preferred embodiments have been disclosed as described above. However, these are not intended to limit the present invention, and any person who is familiar with the technology can use various methods within the spirit and scope of the present invention. Therefore, the protection scope of the invention is based on the contents specified in the claims of the utility model.
