The above base plate (110) is fixedly coupled to the horizontal support shaft (31) by being compressed by the pressure of the wheel nut (38) and positioned between the hub nut (37) and the vehicle body frame (22a) while the shaft hole (112) which is open in the center is inserted through the horizontal support shaft (31). A flat surface (113) is formed around the shaft hole (112) and is parallel to the contact surface (A) of the hub nut (37), having a diameter relatively larger than the contact surface (A) of the hub nut (37). An inclined surface (114) is formed at a certain angle (θ) from the edge of the flat surface (113). It further includes a support plate (140) having a through hole (141) formed in the center and formed in a plate shape corresponding to the flat surface (113), inserted through the horizontal support shaft (31), positioned between the hub nut (37) and the base plate (110) so as to face the flat surface (113), and supporting the flat surface (113) while being compressed by the pressure of the wheel nut (38). A bicycle wheel cover device characterized in that the base plate (110) has a reinforcing bent portion (111) formed laterally at the edge end and extended along the circumference.

  4. In claim 1, The above base plate (110) is, A ventilation hole (115) is formed that is open to the side to allow wind blowing from the side to pass through, and The above outer image member (120) and inner image member (130) are, It is formed in the form of an adhesive sheet with an advertising image or a decorative image printed on one side and an adhesive (121, 131) applied on the other side, and is placed on the base plate (110) with the other side attached to the outer or inner side of the base plate (110) so as to cover the through hole (141), and is made of a cutable sheet material so that a position corresponding to the ventilation hole (115) can be selectively cut to expose the ventilation hole (115) to the outside. A bicycle wheel cover device characterized by having a cutting line (L) of the same shape as the ventilation hole (115) formed at a position corresponding to the ventilation hole (115), so that when cutting each image member (120, 130), the ventilation hole (115) can be exposed to the outside simply by pulling the cutting line (L).

Description

Bicycle wheel cover apparatus that is easy to attach and detach The present invention relates to a bicycle wheel cover device that is easy to attach and detach, and more specifically, to a bicycle wheel cover device that is easily attached and detached by being coupled to a horizontal support shaft fixed to a vehicle frame by a wheel nut, and can display an advertising image or decorative image in a stationary state to the outside using the side of the wheelset, thereby providing a decorative effect that allows the bicycle to be used as an advertising delivery medium or decorated according to the user's taste. Generally, bicycles are a means of transportation equipped to move by having a person sit on them and turn the wheels with the power of two legs, and are widely used for exercise or leisure purposes in addition to transportation purposes. Recently, there have been attempts to achieve advertising effects by attaching advertising boards to such bicycles. FIGS. 1 and 2 disclose the configuration of an advertising board device for a bicycle according to the prior art. Referring to the drawing, the conventional bicycle advertising board device is composed of a coupling member (3, 3') that is fastened to the axle (4) of a bicycle wheelset, and an advertising board (2) that is made in the shape of a disc, has an advertising text on its surface, stands upright, is fastened around the circumference of the coupling member (3, 3'), and is placed in the space between the left spoke (1) and the right spoke (1) of the wheelset. Accordingly, the advertising text of the advertising board (2) is exposed to the side to promote an advertising effect. In addition, since the advertising text cannot be seen while moving when the advertising board (2) rotates with the wheel, the coupling member (3, 3') is fastened so that its inner surface slides on the outer surface of the shaft (4), and a weight (5, 5') is mounted on the bottom of the advertising board (2) so that the load is always concentrated on the bottom, allowing the advertising board (2) to stand upright even when the wheel rotates, thereby improving visibility. In addition, in order to insert the above-mentioned advertising board (2) into the interior of the wheelset, that is, between the left spoke (1) and the right spoke (1), the wheelset must be disassembled and then reassembled with the advertising board (2) mounted, or as shown in FIG. 2, a cut line (7) can be formed in the advertising board (2) and the spoke (1) can be passed through the cut line (7) to be inserted into the interior of the wheelset. However, there was a problem in that some spokes (1) could be deformed while being pressed during the insertion of a large advertising board (2) between narrowly spaced spokes (1), and after inserting the advertising board (2), the advertising board (2) had to be fixed to the connecting member (3, 3') with bolts and nuts through multiple nail holes (8, 8', 9, 9', 10, 10', 11, 11'), making assembly cumbersome and increasing the manufacturing cost. In addition, bearings can be used to reduce the frictional force generated between the shaft (4) and the coupling member (3, 3'), but there was a problem in that maintenance costs were incurred due to wear of the bearings from long-term use. FIGS. 1 and 2 are a front cross-sectional view and a side view showing the configuration of a bicycle advertising board device according to the prior art, FIG. 3 is a photograph showing a state in which a bicycle wheel cover device according to a preferred embodiment of the present invention is mounted on each wheelset of the front and rear wheels of a bicycle. FIG. 4 is an exploded perspective view showing a structure in which a bicycle wheel cover device according to a preferred embodiment of the present invention is mounted on a wheelset. FIG. 5a is an exploded side view showing the configuration of a bicycle wheel cover device according to a preferred embodiment of the present invention, FIG. 5b is a front cross-sectional view showing a state in which a bicycle wheel cover device according to a preferred embodiment of the present invention is combined to be positioned between a body frame and a spoke. FIG. 6 is a cross-sectional view showing the configuration of a reinforcing bent portion according to a preferred embodiment of the present invention, FIG. 7 is a side cross-sectional view showing the configuration of the flat surface of the base plate and the support plate according to a preferred embodiment of the present invention, FIG. 8 is an exploded perspective view showing a configuration in which a ventilation hole is formed in a base plate according to a preferred embodiment of the present invention. FIG. 9 is an exploded perspective view showing a configuration in which the ventilation holes of a base plate according to a preferred embodiment of the present invention are selectively exposed. FIG. 10 is a plan view showing a state in which a base plate according to a prefe
