TITLE: QUICK-RELEASE FIXING STRUCTURE FOR A FENDER
OF A BICYCLE
BACKGROUND OF THE INVENTION Field of the Invention
The present invention relates to a fender, and more particularly to a simply structured and easily operable quick-release fixing structure which is 5 capable of assembling the fender onto the front fork of a bicycle or disassembling it therefrom by a simple pressing operation.
Description of the Prior Art
As shown in Figs. 1 and 2, a conventional removable fender D is fixed to a front fork A of a bicycle by a tightening device B and a quick-release fixing 10 structure C. The fender D is provided on its surface with a circular connecting portion D1 which is formed around the periphery thereof with four arc-shaped cavities D2, and at both ends of each of the arc-shaped cavities D2 are formed with an inner wall D21 and an opening D22.
The quick-release fixing structure C includes a control member 10 15 which is formed with a mounting portion 101 and a handle portion 102, and a disc member 11 disposed at the top of the mounting portion 101. The disc member 11 is formed with an annular end surface 111 against which an abutting end A1 of the front forth A is pressed. Below the mounting portion 101 is disposed a connecting member 12, and the mounting portion 101 is provided 20 with four L-shaped engaging blocks 103 around the connecting member 12. The connecting member 12 is formed with a central hole 121. The connecting member 12, the mounting portion 101 of the control member 10 and the disc member 11 are inserted on a bolt 13, and then the tightening device B is screwed with the bolt 13 and then fixed in the front fork A by pressing against the inner 25 surface of the front fork A, so that the fender D is fixed to the front fork A in such a manner that the four engaging blocks 103 of the control member 10 are engaged in the four arc-shaped cavities D2 of the fender D, and the ends of the engaging blocks 103 are inserted in the openings D22 of the arc-shaped cavities D2.
1039406 2
Pulling the handle portion 101 of the control member 10 can install or disassemble the fender D. However, this conventional fender still has the following disadvantages: 1. The engagement of the control member 10 with the fender D is 5 achieved by rotating the mounting portion 102, and in assembly, it is not easy for the user to see the positions of the engaging blocks 103 by looking from above the control member 10, so the user has to try to align the arc-shaped cavities D2 with the engaging blocks 103, then rotates the control member 10 to fix the fender D. however, rotating the control member 10 may cause 10 misalignment of the fender D with respect to the wheel of the bicycle. Therefore, the user has to pull the handle portion 102 of the control member 10 again to readjust the position of the fender D even after the fender D is fixed.
2. The quick-release fixing structure C is engaged with the fender D in a rotating member (by pulling the control member to rotate), and the engaging 15 structures of the quick-release fixing structure C and the fender D are located in the rotating direction, so the engaging structures or the handle portion 102 of the control member 10 are likely to be damaged if the user pulls the handle portion 102 too hard.
3. since the operation of the quick-release fixing structure C is 20 controlled by the rotation of the control member 11, it has to use the disc member 11 and the connecting member 12 to prevent the control member 11 from being worn out by the front fork A and the fender D during rotation, which makes the structure complicated and increases the cost.
The present invention has arisen to mitigate and/or obviate the 25 afore-described disadvantages.
SUMMARY OF THE INVENTION
The primary object of the present invention is to provide a simply structured and easily operable quick-release fixing structure which is capable of assembling the fender onto the front fork or disassembling it therefrom by a 30 simple pressing operation.
To achieve the above object, a quick-release fixing structure for a fender of a bicycle in accordance with the present invention comprises: a mounting member, an engaging member, and a control member.
The mounting member is connected to an end of the front fork, in a 3 bottom of the mounting member is formed a receiving cavity whose axial direction is defined as a longitudinal direction. The mounting member is formed around its periphery with two penetrating holes which penetrate through the periphery of the mounting member to leave two cutting grooves on an inner 5 surface of the receiving cavity, and the cutting grooves are in communication with the receiving cavity and the penetrating holes. An axial direction of the penetrating holes is defined as a transverse direction, an elastic piece extends from the mounting member, and a bolt which extends in the longitudinal direction is inserted through the receiving cavity and screwed with the 10 tightening device.
The engaging member is disposed on the fender and received in the receiving cavity of the mounting member and formed around its periphery with two arc-shaped cutting grooves for mating with the arc-shaped cutting grooves of the mounting member.
15 The U-shaped control member is provided with a pressing section and two engaging sections at both ends of the pressing section. The engaging sections of the control member are inserted in the penetrating holes, and each of the engaging sections is formed on an inner surface thereof facing the engaging member with an arc-shaped groove for mating with the cutting groove of the 20 mounting member. The elastic piece of the mounting member is capable of pressing against the pressing section of the control member to make the arc-shaped grooves of the control member misaligned with the cutting grooves of the mounting member, so that the engaging member is engaged with the j mounting member, or make the arc-shaped grooves of the control member i 25 aligned with the cutting grooves of the mounting member, so that the engaging member is disengaged from the mounting member.
The engaging structures are all engaged in the transverse direction, while the force for pushing the quick-release fixing structure is applied in the ! longitudinal direction, which enables the quick-release fixing structure to have a 30 relatively strong structural strength, so as to prevent the quick-release fixing structure from being damaged when it is pushed too hard.
The engaging member can also been integral with the fender and inserted directly in the mounting member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for 30 purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Referring to Figs. 3,4, 5 and 7B, a quick-release fixing structure C for a fender of a bicycle in accordance with a preferred embodiment of the present invention is used to fix a fender D to the front fork A of the bicycle by 5 cooperating with a tightening device B and comprises: a mounting member 20, an engaging member 30 and a control member 40.
The mounting member 20 is connected to an end of the front fork A, and abutting edge A1 of the end of the front fork A is pressed against a top 5 surface 21 of the mounting member 20. In the bottom of the mounting member 20 is formed a receiving cavity 23 whose axial direction is defined as a longitudinal direction Y, and the receiving cavity 23 is formed around its inner surface with two opposite arc-shaped surfaces 231 and two opposite restricting surfaces 232. In the bottom of the receiving cavity 23 is formed a tapered hole 10 24 tapering toward the front fork A. The mounting member 20 is formed around its periphery with two opposite arc-shaped surfaces 25, and in each of the arc-shaped surfaces 25 is defined a penetrating hole 26 which penetrates through the arc-shaped surfaces 25 to leave a cutting groove 261 in each of the arc-shaped surfaces 231, and the cutting grooves 261 are aligned to and in 15 communication with the receiving cavity 23 and the penetrating holes 26. The axial direction of the penetrating holes 26 is defined as a transverse direction X. An elastic piece 27 extends from an end of one of the arc-shaped surfaces 25 of the mounting member 20, and a bolt 29 which extends in the longitudinal direction Y is inserted through the receiving cavity 23 and screwed with the 20 tightening device B.
As shown in Fig. 4, in the center of the top surface 21 of the mounting member 20 is formed a polygonal protrusion 22, the mounting member 20 is further formed on its periphery with a flat surface 28 located corresponding to the elastic piece 27, and at the conjunction between the elastic piece 27 and the 25 mounting member 20 is formed a deformable portion 271.
The engaging member 30 is formed around its periphery with two opposite arc-shaped surfaces 301 and two opposite positioning surfaces 302 and received in the receiving cavity 23 of the mounting member 20 in such a manner that the two arc-shaped surfaces 301 and the two positioning surfaces 302 of the 30 engaging member 30 are aligned with the two arc-shaped surfaces 231 and the restricting surfaces 232 of the mounting member 20, respectively. Each of the arc-shaped surfaces 301 of the engaging member 30 is formed with an arc-shaped cutting groove 31 for mating with the arc-shaped cutting grooves 261 of the mounting member 20. In this embodiment, the restricting surfaces 232 6 and the positioning surfaces 302 are flat, so that the engaging member 30 can be engaged in the receiving cavity 23 of the mounting member 20, and the arc-shaped cutting groove 31 mates with the cutting groove 261 to form a complete hole.
5 The control member 40 is a U-shaped structure which is provided in the middle with a pressing section 401 and two engaging sections 402 at both ends of the pressing section 401. The engaging sections 402 of the control member 40 are inserted in the penetrating holes 26. Each of the engaging sections 402 is formed at an end thereof with a clamping slot 41 and a positioning protrusion 42 10 beside the clamping slot 41, so that when the clamping slots 41 are compressed, the engaging sections 402 can be inserted and fixed in the penetrating holes 26 by pressing the positioning protrusions 42 against the outer edge of the penetrating holes 26. An inner surface (facing the engaging member 30) of each of the engaging sections 402 is formed with an arc-shaped groove 43 which is 15 shaped corresponding to the configuration of the arc-shaped surfaces 231 of the receiving cavity 23 of the mounting member 20, so that when the control member 40 is inserted in the penetrating holes 26, the arc-shaped groove 43 will mate with the cutting groove 261 of the mounting member 20.
As shown in Figs. 5 and 6, the elastic piece 27 of the mounting member 20 20 is pressed against the pressing section 401 of the control member 40 to make the arc-shaped grooves 43 of the control member 40 misaligned with the cutting grooves 261 of the mounting member 20, so that the engaging member 30 is engaged with the mounting member 20, or make the arc-shaped grooves 43 of the control member 40 aligned with the cutting grooves 261 of the mounting 25 member 20, so that the engaging member 30 is disengaged from the mounting member 20.
Referring then to Figs. 5-8B, pressing the pressing section 401 of the control member 40 can assemble the fender D to the mounting member 20 which is fixed to the front fork A or disassemble the fender D from the mounting 30 member 20.
