Description

Tire detachable wheel in using transfer device and movement device

The present invention relates to a wheel used for a transportation means such as a suitcase or a carrier and a transportation means such as an inline skate or a kickboard.

The wheels used in the existing vehicles and vehicles consisted of plastic hubs and polyurethane tires. When the tires were molded to increase the coupling between the hub and the tires, the hubs were placed in the tire forming mold. The wheel was manufactured by molding a tire in a state. The wheels manufactured in this way have the advantage that the tires are not detached from the center hub because of the excellent binding force between the center hub and the tire, but it causes the following disadvantages.

First, in the process of molding the tire, the center of the hub and the center of the tire may be formed in a state where the tire does not coincide. In this case, the wheel is shaken when the wheel rotates, causing unnecessary energy loss and discomfort during driving. Brings about. In addition, when the tire is worn out, the wheels need to be replaced. Existing wheels cannot be separated from the center hub and the tires, so the entire wheel has to be discarded.

In order to solve the problems of the existing wheels as described above, the central hub and the tire should be separated and combined with each other, and the tire should not be separated from the central hub.

The present invention is to provide a wheel that can be separated and combined with the metal hub and the tire can be replaced only when the tire is worn out, the tire is not separated from the center hub even when the user's extreme operation.

The configuration of the present invention for achieving the above object will be described with reference to the accompanying drawings.

(A) of FIG. 1 is a front view of the present invention, (b) is a view showing a back view of the present invention, (a) of FIG. 2 is a perspective view of the present invention, (b) is a left side view of the present invention Drawing.

As shown, the subject innovation is not much different from the existing wheels in appearance. However, in order to achieve the object of the present invention to detach the central hub and the tire 30, the central hub is composed of the left hub 10 and the right hub 20 on an arbitrary basis. That is, the present invention consists of the left hub 10 and the right hub 20 and the tire 30 and the fastening means. As a fastening means, a plurality of bolts 33 and nuts 34 are used, which serves to fix the tire 30 while engaging the left hub 10 and the right hub 20. The left hub 10 and the right hub 20 have a substantially symmetrical structure but are slightly different in detail and will be described below.

3 is an exploded perspective view of the present invention.

As shown, the subject innovation consists of the left hub 10 and the right hub 20 and the tire 30 and a plurality of bolts 33, nuts 34. The left hub 10 and the right hub 20 have a symmetrical structure, and have a means for preventing the tire 30 from being separated from the central hub. The left hub 10, the right hub 20, and the tire 30 are provided with a plurality of through holes 16, 26, and 32, and then assembled by adjusting the positions of the through holes 16, 26, and 32. Insert the 33 into the through holes 16, 26, 32 and fix it with the nut 34 to form a completed wheel. The through holes 16, 26, and 32 are not well represented in the drawings, and thus will be represented in the following drawings.

(A) is a perspective view of a hub, (b) is a figure which shows the left side view of a hub, FIG. 5 (a) is a perspective view of a left hub, (b) is a figure which shows the back perspective view of a left hub.

As shown, the left hub 10 includes a bearing seat 11 capable of seating a bearing at its center portion, a rim 14 for seating the tire 30, and the bearing seat 11 and rim 14. The connection support 13 for connecting the tire and the tire guard 15, which serves to hold the tire 30 from the side so that the tire 30 is not separated is formed integrally. Similarly, the right hub 20 also includes a bearing seat 21, a rim 24, a connecting support 23, and a tire guard 25 in one body.

The tire guards 15 and 25 formed on the left hub 10 and the right hub 20 serve to hold the tires 30 mounted on the rims 14 and 24 from both sides so as not to be separated. In addition, a plurality of through holes 16 and 26 are formed in the tire guards 15 and 25 so that the bolts 33 may pass therethrough. In addition, a rectangular nut fixing groove 18 is formed along the tire guard 15 so as to fix the nut 34 on the outer surface of the tire guard 15 of the left hub 10, and the right hub 20. The outer side of the tire guard 25, the bolt groove 28 of the rectangular shape is formed along the tire guard 25 so that the head of the bolt 33 can enter. The nut fixing groove 18 is formed to hold the nut 34 even when no assembly or disassembly. In addition, the bolt groove 28 is for preventing the head of the bolt 33 from jumping outward unnecessarily during assembly.

6 is a perspective view and a partially enlarged view of the tire.

As shown, the tire 30 has a semi-circular cross section and has an insertion protrusion 31 protruding inward, which is a surface abutting with the rims 14 and 24 of the left and right hubs 10 and 20. A plurality of through holes 32 are formed in the insertion protrusion 31 in the rotation axis direction. Since the bolt 33 penetrates and assembles in the plurality of through holes 32, the tire 30 can be reliably prevented from being separated from the central hub.

7 is a view showing a cutaway and a partial enlarged view of the present invention, Figure 8 (a) is a cutaway perspective view of the present invention, (b) is a view showing a rear perspective view and a partial enlarged view.

As shown, the insertion protrusion 31 formed on the tire 30 is surrounded by the rims 14 and 24 and the tire guards 15 and 25 formed on the left hub 10 and the right hub 20, and thus the tire. 30 does not deviate from the central hub. Moreover, since the plurality of bolts 33 are assembled through the plurality of through holes 32 formed in the insertion protrusion 31, the tire 30 is reliably prevented from being separated during use.

The means for coupling the left hub 10 and the right hub 20 is the coupling force of the plurality of bolts 33 and the nut 34. Part of the contact with the ground when using the combined tire 30, the force received by the tire 30 is mainly transmitted to the rims 14 and 24 of the left hub 10 and the right hub 20. Therefore, the rim 14 of the left hub 10 and the rim 24 of the right hub 20 are also required to maintain the shape. For this purpose, the ends of the rim 14 and the right hub of the left hub 10 are required. The end of the rim 24 of the left hub 10 is formed in the form of a recessed groove 17 in the form of a dent so that the ends of the rim 24 of the 20 may be engaged with each other. 24) the fastening protrusions 27 are formed in the protruding shape. The fastening groove 17 and the fastening protrusion 27 are engaged with each other to disperse the forces when the tire 30 transmits the force received from the ground to the rims 14 and 24 to maintain the overall rigidity of the central hub. do. In addition, the fastening groove 12 is formed at the end of the bearing seat 11 of the left hub 10, and the fastening protrusion 22 is formed at the end of the bearing seat 21 of the right hub 20, thereby assembling. Poetry interlock with each other. This serves to increase the overall stiffness of the central hub.

On the bearing seats 11 and 21 of the left hub 10 and the right hub 20, protruding jaws 19 and 29 are formed to protrude in the center direction. The protruding jaws 19 and 29 serve to limit the depth of the bearing inserted into the bearing seats 11 and 21.

As shown in FIG. 8B, a nut fixing groove 18 is formed along the tire guard 15 on the outer surface of the tire guard 15 of the left hub 10. As shown in the enlarged view, the nut fixing groove 18 serves to hold the nut 34 so as not to rotate. This allows the nut 34 to be assembled or disassembled without tools. Prevents it from sticking out of the wheel. A bolt groove 28 is also formed along the tire guard 25 on the outer side of the tire guard 25 of the right hub 20, thereby preventing the bolt 33 from protruding to the outside.

According to the present invention, there is no phenomenon that the tire 30 slips in the rotational direction with respect to the center hub, and the phenomenon that the tire 30 is separated from the center hub does not occur. In addition, since the tire 30 can be detached from the central hub, only the tire 30 is replaced when the wheel is replaced, thereby providing the user with the advantage of using the tire 30 of various sizes and materials. Can be.
