The present invention relates to a wheel for furniture attached to the bottom surface of the furniture or bag.

In the conventional furniture wheels, since the frame of the wheel integrated with the eccentric shaft is assembled at the center of the connection part, when the wheel is assembled on the lower surface of the heavy furniture, the eccentric shaft contacted with the furniture is on one side. There were many cases of itching and wheel breakage.

Among the wheels attached to the legs of the swivel chair, the weight of the person sitting on the chair is the center of the eccentric shaft connected to the leg surface of the chair. The wheels withstand the weight with the angle of inclination in the eccentric shaft and the chair body loses its center because the eccentric shaft is twisted in the frame of the wheel every time the chair moves.

The present invention has been devised to solve the above-mentioned drawbacks, and the structure and effect will be described in detail by the accompanying drawings as follows.

The furniture wheels 1 are placed in the lowered double-sided shaft holes 5 of the upper base 2 and the grooves 6 and the long holes 7 in both side holes 8, 8 ′, 8 ″ of the lower base 3. Fixing to the shaft hole 5 and the hole 8 of the upper expectation 2 and the lower expectation 3 while installing the spring 13 as a protrusion on the inner surface of the upper expectation 2 and the inner of the lower expectation 3 during assembly. The shaft 9 was fitted and the shaft 11 of the wheel 10 was fitted with the recess 6 and the hole 8 ', and the shaft 12 was passed through the long hole 7 and the hole 8 ″, respectively. The supporting jaw 4 on one side of the base 3 connected the bearing 15 to the eccentric shaft 14 toward one side of the upper surface of the upper expectation 2 which blocked the side hole of the upper expectation 2.

When the furniture wheel 1 of the present invention configured as described above is attached to the bottom of the leg of the furniture or the bottom of the bag, the shaft 9 and the hole 8 of the upper and lower bases 2 and 3 are centered on the fixed shaft 9. The upper and lower bases (2) and (3) have a shaft (12) penetrating the hole (8 ″) and the long hole (7) by the restoring force of the spring (13) in contact with the lower surface of the long hole (7), The shaft 11 is in contact with the inner surface of the recess 6 and is separated from the state where the side of the upper expectation 2 is covered by the supporting jaw 4 of the lower expectation 3. 2) The spring 13 in the 3 is contracted and the shaft rod 12 is centered on the shaft hole 5 and the hole 8, and the shaft 11 of the wheel 10 is recessed to the upper surface of the long hole 7. 6) moved to the outer side and at the same time the support base (4) of the lower expectation (3) has the elasticity to be in contact with the side of the upper expectation (2), while the direction of the furniture to be moved when moving furniture The spring 15 of the mandrel 14 is rotated and the wheels 10 connected to the upper and lower bases 2 and 3 in the rear direction are installed on both sides of the shaft 11 so that the furniture is balanced by the two wheels 10. Since the cushioning function is supported by the restoring force of the spring 13 which is proportional to the weight of the furniture, the two wheels 10 move smoothly with elasticity when the furniture is moved, and the furniture can be conveniently moved. The weight according to the weight applied to the eccentric shaft 14 connected to the shaft 12 into the long hole 7 and the recess 6 in which the upper base 2 and the lower base 3 are joined by the restoring force of the spring 13. ) And the shaft 11 acts as a shock absorber, and the wheel 10 is brought into close contact with each other to balance the shaft 11 so that the protrusion is smoothly rotated even when the wheel moves over the furniture while moving the furniture. It is designed to preserve the stored contents.

Claims (1)

In the downwardly double-sided shaft hole 5 of the upper base 2, the hole 8 of the lower base 3 is fitted with the fixed shaft 9, and the shaft of the wheel 10 in the groove 6 and the hole 8 (11) by inserting the shaft (12) through the long hole (7) and the hole (8 ″), respectively, characterized in that the spring 13 is elastically installed by the projections of the upper base (2) and the lower base (3) One furniture wheel.
