Description

Field of the invention

[0001] The present invention relates to the technical field of bicycle accessories and, in particular, to a bicycle fender mount. State of the art

[0002] Bicycles are equipped with mudguards attached to the conventional wheel axles of the front and rear wheels in conjunction with the frame to prevent water, sand, gravel and other foreign objects lying on the road from being thrown into the air by the tires and to provide the following protection: 1. Reducing the splashing of water, sand and gravel onto the user; 2. Avoiding splashing of water, sand and gravel onto pedestrians; 3. Reducing the ingress of water, sand and gravel into parts such as brake calipers, switchgear, lights, etc.

[0003] A common method of assembling mudguards is to connect the frame and mudguards together using several support rods, with the mudguards mounted over the bicycle tires to achieve the desired purpose of locking.

[0004] When replacing or repairing conventional support rods and fenders, the wheel axle nuts must first be removed before the support rods and fenders can be removed for repair. However, removing the nuts will affect the calibration of the wheel axles, causing problems with subsequent adjustments. Object of the invention

[0008] It is based on the Fig. 1 to 5, which show a bicycle mudguard holder according to the invention, which can be attached to the two ends of the wheel axle 93 of a frame 92 by means of a plurality of screw nuts 91 and serves to be combined with a mudguard 94 and comprises a plurality of tube seats 10, a first U-shaped holder 20, a second U-shaped holder 30, a plurality of connecting bushings 40, a plurality of bolts 50, a plurality of seals 60 and a plurality of ring pieces 80.

[0009] Here, a wheel axle 93 (state of the art) is arranged in coordination with the frame 92 on the front or rear wheel fork, wherein several screw nuts are provided for locking in order to tension and position the wheel axle 93 in cooperation with the frame 92.

[0010] A respective pipe seat 10 has an approximately T-shaped contour and has an axial section 12 and a radial section 14.

[0011] A respective axial section 12 has a shaft hole 122 running through its cutting surface, into which the wheel axle 93 can be inserted.

[0012] A respective radial section 14 extends outwardly from one side of the corresponding axial section 12, wherein a part of the outer peripheral side of a respective radial section 14 is provided with an external thread 142.

[0013] The first U-shaped bracket 20 has a first segment 22 and a second segment 24 arranged symmetrically thereto at each end, wherein the cutting surfaces of the first segment 22 and the second segment 24 are each provided with an inner screw hole 26.

[0014] The second U-shaped bracket 30 has a third segment 32 and a fourth segment 34 arranged symmetrically thereto at each end, each of which is connected to the first segment 22 and the second segment 24. In the implementation, an included angle is provided between the first U-shaped bracket 20 and the second U-shaped bracket 30.

[0015] A respective connecting bushing 40 surrounds the first segment 22 or second segment 24 matched to it and has a stepped bore 42 and an internal thread 44.

[0016] A respective stepped bore 42 extends along the extension direction of the corresponding connecting bushing 40 and has a large diameter section 422 and a small diameter section 424.

[0017] A respective internal thread 44 is provided at a predetermined position of the corresponding stepped bore 42. In the implementation, a respective internal thread 44 is provided at the large diameter portion 422 of the corresponding stepped bore 42.

[0018] One end of each bolt 50 is inserted through the corresponding connecting bushing 40 and then screwed into the corresponding inner screw hole 26, with the other end abutting the stepped end surface of the corresponding stepped bore 42 to define the corresponding connecting bushing 40 so that it movably surrounds the first segment 22 or the second segment 24. The two ends of each bolt 50 are each provided with a shaft head 52 and a shaft body 54.

[0019] A respective shaft head 52 has a profile that is larger than the cross-section of the small diameter portion 424 of the corresponding stepped bore 42, wherein the end surface of the shaft head remote from the corresponding shaft body 54 has a recess in the form of a polygonal hole 522.

[0020] After each shaft body 54 has been inserted through the small diameter portion 424 of the corresponding stepped bore 42, it is screwed into the corresponding inner screw hole 26.

[0021] A respective seal 60 surrounds the corresponding shaft body 54 and is housed in the large diameter portion 422 of the corresponding stepped bore 42 and is urged by the corresponding shaft head 52 to bear against the stepped surface of the large diameter portion 422 of the corresponding stepped bore 42.

[0022] The ring pieces 80 surround the outer peripheral side of the wheel axle 93 and are respectively arranged at the two ends of the axial section 12 of the corresponding tube seat 10. In practice, the ring pieces 80 are made of a soft material (e.g., plastic) to increase the tightness between the intersection surfaces provided at the two ends of a respective axial section 12 and the frame 92 or the screw nuts 91 (eliminating the gap between them), and also to absorb vibrations during cycling.

[0023] The various components and assembly methods of the bicycle fender mount according to a preferred embodiment of the present invention have been described above. The operating characteristics of the embodiment of the present invention are described below.

[0024] It is based on the Fig. 1 to 7. First, the screw nuts 91 located at both ends of the wheel axle 93 are unscrewed, then the shaft holes 122 of the axial sections 12 of the tubular seats 10 are aligned with the two ends of the wheel axle 93 and placed thereon, then the unscrewed screw nuts 91 are screwed again to the wheel axle 93 in order to fasten the tubular seats 10 to the two ends of the wheel axle 93.

[0025] The connecting bushings 40 located on the first and second sections 22, 24 are each aligned with the corresponding tube seat 10 matched to them, wherein the internal thread 44 of a respective connecting bushing 40 is screwed to the external thread 142 of the radial section 14 of the corresponding tube seat 10 in order to connect the first and second segments 22, 24 to the corresponding tube seat 10 in series, whereby the first and second U-shaped brackets 20, 30 each bridge the outer peripheral side of the bicycle tire so that a mudguard 94 can be combined with them and suspended over the bicycle tire.

[0026] When mudguards 94 or luggage carriers of various types need to be repaired or replaced, the repair or replacement can be carried out simply by separating the connecting bushings 40 and the tube seats 10, without having to loosen the screw nuts 91 again, in order to avoid the laborious calibration of the wheel axles 93.

[0027] It will be Fig. 8, which shows another embodiment of the nut 91 according to the present invention. To facilitate the user's ability to quickly assemble or disassemble the nut 91 without the use of tools, a lever portion 912 extends from one side of each nut 91 to allow the user to exert force to rotate the nut 91.

[0028] The above description represents only preferred embodiments of the invention and is not intended to limit the claims. All equivalent changes and modifications that can be made by one skilled in the art in accordance with the description and drawings of the invention are within the scope of the present invention.
