Abstract

The present invention relates to a wheel of a chair or a storage box that requires rotational movement, and is a bottom part of the storage box. A separate shaft (8) is installed as a component wheel for the problem of the disassembly and detachment of the assembly of the shaft, which can be generated by the pressing force connected to the underlay of the chair (figure 4) concentrated on the shaft (7). For example, to improve the complicated problems in the manufacturing and structural, such as a small bead (2) is precisely divided into the inside of the rotating wheel body (1) directly connected to the recess 10 of the base (figure 5) (2) The load will be distributed to the depressing gravity, and then the rolling of each other with the large beads (3) to be embedded is such that the smoothness of the mutual grains of the large beads (3) and the small beads (2) and the abrasion resistance are eliminated. There is a feature that the groove (5) is installed on the outsider (body) is configured for the removal of foreign matter and the buffering force of the pin during the operation of the large beads (3).

Description

Rotating Wheels {Roundin WheeL}

The present invention relates to products that require free rotation (360 degrees) and forward and backward movement, that is, wheels attached to the bottom of chairs, storage boxes, steel safes, refrigerators, etc. The structure is complicated by the parts that are coupled to the chair support and the wheels that constitute the separate axis for the forward and backward movement and the axis for rotation attached to the chair support, so there is a problem to reduce and move the rotation radius is an improved design.

They have a separate axis of rotation for nearly 360-degree rotation, and at the bottom of the axis, they also consist of wheels for forward and backward movement, which simultaneously rotate and move forward, but the complexity of the structure is large. There is a drawback that it is restricted in use, such as not applicable to storage.

The present invention was devised to solve all the drawbacks that are limited to use as described above. It is designed to facilitate smooth 360-degree rotation and forward / backward movement. The weight that is pushed down by installing the grooves in several places where the SMALL BALL is equally divided on the upper surface and installing the LARGE BALL at the bottom of the ball is distributed at the same time. 360 degree rotation and forward and backward smoothly.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic view of the present invention, FIG. 2 is an exploded perspective view of the present invention, and FIG. 3 is an all-weather perspective view assembled in the present invention, and FIG. 4 is an assembly view of a product currently in use. It is a combined assembly diagram of the product of the present invention.

As shown in the figure, the rotary wheel of the present invention, which is fitted as a single operation to be inserted into the recess 10 of the base 9 of the chair of FIG. 5, is exactly equal to the inner upper end of the body 1. After seating the small beads (2) in the grooves (4) of the various places, the large beads (3) works smoothly, so that the end of the end (6) is properly tightened so that the rolling and turning operations are activated. B. A groove 5 was formed in the outer outer body of the large bead 3 in case foreign matter entered.

The base of the chair currently being used (such as the wheel of a chair or a storage box for moving) (FIG. 4) is weighted to the shaft 7 which is assembled and connected to the recess 10 when a person sits or contains an object. This is because the weight of the shaft 7 is displaced and distorted, and not only this, but the concentrated weight is applied to the shaft 8 of the wheel. In the present invention, but limited to the application of the large bead (3) inserted directly under the small bead (2) built in the inside of the rotary wheel directly assembled in the recess 10 of the base (figure 5) is smooth Since there is no obstacle to 360-degree rotation and forward / backward movement, the force distributed by the small bead 2 is distributed firstly, and the frictionless mutual rotation operation of the small bead 2 and the large bead 3 is performed with the rotating wheel (4 degrees). Made easy compared to) Of course, almost perfect rotation and forward and backward, such as smooth rolling operation is implemented.

As described above, since all the principles of operation are utilized by the perfect cloud of beads, the effects of the long life of the overall life and simple appearance are expected by improving the wear resistance and durability.

Claims (1)

Form grooves (4) in various places that are exactly equally located on the upper surface of the wheel body (1), and then place small beads (2) in them, and then insert the large beads (3) to smoothly roll and escape the beads. In order to prevent it from being properly tightened at the end part 6, the assembly part and the outer part of the large bead 3 are provided with a plurality of grooves 5 so as to buffer foreign matters and buffer the force during the rotation of the beads.
