DETAILED DESCRIPTION OF THE INVENTION
As shown in FIG. 1 and FIG. 2, an accessory assembly 100 of the preferred embodiment of the present invention is mounted on a handlebar 200 of a bicycle (not shown). The accessory assembly 100 includes a mounting frame 10 and a plurality of accessories.
As shown in FIG. 3 and FIG. 4, the mounting frame 10 has a frame member 12 and a pressing member, which is a bolt 16 in the present embodiment. The frame member 12 is a tubular member having a central hole 122 at a center, and the handlebar 200 is able to be inserted into the central hole 122 of the frame member 12. The frame member 12 is further provided with three openings 124, three coupling slots 126, and two holding portions 128, 128′. The openings 124 are on a surface of the frame member 12, and are arranged separately in different radial directions of the central hole 122, wherein the openings 124 extend in an axial direction of the frame member 12, which is an extending line of the center of the frame member 12, and are communicated to the central hole 122. The coupling slots 126 are on the surface also and between each two of the neighboring openings 124, wherein the coupling slots 126 are arranged in different radial directions of the central hole 122. The coupling slots 126 are grooves in the present embodiment without being communicated to the central hole 122. In more details, each of the coupling slots 126 can be divided into an upper portion and a lower portion, wherein a width of the lower portion is wider than that of the upper portion. The coupling slots 126 each have an elongated direction parallel to the axial direction of the frame member 12. The coupling slots 126 are open at an end of the frame member 12, which are defined as open ends. The holding portions 128 are two protrusions projected from the surface of the frame member 12. The frame member 12 has a gap 14 between the holding portions 128, 128′, and the gap 14 has opposite ends extending to one of the openings 124 and an end of the frame member 12. The holding portion 128 is provided with a hole 128a thereon, and the other holding portion 128′ is provided with a threaded hole 128b. 
The bolt 16 has a head 162 and a threaded rod, and the threaded rod is screwed into the threaded hole 128b through the hole 128a. By screwing the bolt 16, the head 162 abuts against the two holding portions 128, 128′ to narrow a width of the gap 14, and therefore the frame member 12 can be firmed mounted on the handlebar 200.
The accessories include a light 18 (headlight), a derailleur controller 24, and a brake lever 32. In practices, any accessories which can be mounted on the handlebar 200, such as bells, cell phone holders, and GPS devices, could be incorporated in the present invention.
The light 18 is connected to a sliding member 20, and the sliding member 20 has a coupling portion 202 and a threaded hole 204. The shape of the coupling portion 202 is complementary to the coupling slots 126 on the frame member 12, so that the coupling portion 202 can enter the coupling slot 126 through its open end. The sliding member 20 has an extending portion, on which the threaded hole 204 is provided. While the coupling portion 202 is engaged in the coupling slot 126, the extending portion is over the surface beside the coupling slot 126, and a bolt 22 can be screwed into the threaded hole 204 and presses the surface of the frame member 12 when the coupling portion 202 is moved to a predetermined position. The sliding member 20 is tilted when the bolt 22 is tightened to secure the coupling portion 202 in the coupling slot 126. As a result, the light 18 is firmly mounted on the handlebar 200.
The derailleur controller 24 has a base 26, and the base 26 includes a main body 28 and a sliding member 30. Typically, the main body 28 is a block connected to the derailleur controller 24, and the sliding member 30 is a protrusion projected from the main body 28. The sliding member 30 has a coupling portion 302, which has a shape complementary to the coupling slots 126 of the mounting frame 10. The same as above, the coupling portion 302 is engaged in the coupling slot 126, and a bolt 31 abuts against a surface of the frame member 12 to secure the base 26. As a result, the derailleur controller 24 is firmly mounted on the handlebar 200.
The brake lever 32 has a sliding member 34. The same as above, the coupling portion 32 has a coupling portion 342 to be engaged in the coupling slot 126, and a bolt 36 is screwed into a threaded hole 344 to secure the brake lever 32 on the handlebar 200.
The mounting frame 100 and the sliding members are so called a mounting device to connect the accessories 18, 24 to the handlebar 200, and the accessories 18, 24, and 32 are around the frame member 12. In other words, the accessories 18, 24, and 32 are mounted on the handlebar 200 in parallel, not in series.
FIG. 6 shows an alternative pressing member including a press handle 40 and a connecting rod 42, wherein the press handle 40 has a head 402, which is in a shape of a cylindrical cam. The head 402 is pivotally connected to an end of the connecting rod 42, and abuts against a holding portion 129. Another end of the connecting rod 42 passes through the holding portion 129 and another holding portion 129′, and a nut 44 is connected to the connecting rod 42 to abut against the holding portion 129′. A width of a gap 14′ between the holding portions 129, 129′ is narrowed by pressing the press handle 40 to urge the holding portions 129, 129′ to move towards each other. Therefore the mounting frame 10′ is firmly mounted on the handlebar 200.
As shown in FIG. 7, a mounting frame 45 has a coupling slot 452 which can be divided into an upper section 452a and a lower section 452b, wherein the upper section 452a is above the lower section 452b, and the upper section 452a is narrower than the lower section 452b. The sliding member 46 includes a main body 48 and a coupling base 50, wherein the main body 48 has a hole 482, and the coupling base 50 has a threaded hole 502. A part of the main body 48 is exposed out of the coupling slot 452, and a width of said part is wider than that of the upper section 452a. Another part of the main body 48 goes into the upper section 452a, and the coupling base 50 is received in the lower section 452b. A bolt 56 is screwed into the threaded hole 502 of the coupling base 50 through the hole 482 of the main body 48, and a head 562 of the bolt 56 abuts against the main body 48, which urges the part of the main body 48 exposed out of the coupling slot 452 to abut against a peripheral surface of the mounting frame 45. At the same time, the coupling base 50 abuts against walls of the upper section 452a and the lower section 452b, and therefore the mounting frame 45 is firmly mounted.
As shown in FIG. 8, a mounting frame 60 includes a main frame 602 and a plurality coupling rails 604 which extend in an axial direction of the main frame 602. Hereafter we take one of the coupling rails 604 as an example for explanation. The main frame 602 has a central hole 602a fitted on the handlebar 200. The coupling rails 604 are arranged in different radial directions of the central hole 602a, and each of the coupling rails 604 has a neck 604a and a head 604b, wherein the neck 604a is extended from a peripheral surface of the main frame 602. A sliding member 62 is provided for engaging the light 18, wherein the sliding member 62 has a coupling slot 622 which is complementary to the coupling rail 604 in shape. The coupling slot 622 is fitted into the coupling rail 604 through an end of the coupling rail 604, and the sliding member 62 is movable along the coupling rail 604. Similarly, the sliding member 62 is firmly engaged onto the mounting frame 60 by screwing a bolt 64 into a threaded hole 624 of the sliding member 62 and abutting the bolt 64 against the head 604b of the coupling rail 604.
As shown in FIG. 9, a mounting frame 66 includes a main frame 662 and a plurality of coupling rails 664, wherein the main frame 662 has a central hole 662a. The coupling rails 664 are engaged to the main frame 662 by a plurality of bolts 68, and are arrange in different radial directions of the central hole 662a. Each of the coupling rails 664 is gradually getting narrower from top to bottom, and a coupling slot 666 is formed between two neighboring coupling rails, wherein the coupling slot 666 is wider at a bottom thereof. Whereby, the mounting frame 66 can engage two different kinds of sliding members 70, 70′, wherein the sliding member 70 is engaged in one of the coupling slots 666, and the sliding member 70′ is engaged to one of the coupling rails 664.
As shown in FIG. 10, a mounting frame 72 includes a first main frame 722 and a second main frame 724 which are engaged with each other to form a central hole 726 therebetween. The first main frame 722 and the second main frame 724 respectively have two opposite ends, wherein the ends of the first main frame 722 respectively have a first holding portion 722a, and the ends of the second main frame 724 respectively have a second holding portion 724a which corresponds to one of the first holding portions 722a. A gap 728 is respectively formed between each of the first holding portions 722a and the corresponding second holding portion 724a. With two pressing members, which are two bolts 74 in the preferred embodiment, respectively screwed into a threaded hole 724b of one of the second holding portions 724a through one of the first holding portions 722a, a width of each of the gaps 728 can be narrowed by urging each of the first holding portions 722a to move towards the corresponding second holding portion 724a. As a result, the first main frame 722 and the second main frame 724 hold the handlebar 200 together, and therefore the mounting frame 72 is firmed mounted on the handlebar 200.
As shown in FIG. 11, a mounting frame 76 similarly includes a first main frame 762 and a second main frame 764, except that one of the two opposite ends of the first main frame 762 is pivotally connected to the second main frame 764, and the other end of the first main frame 762 has a holding portion 762a, while the second main frame 764 has another holding portion 764a. A gap 766 is formed between the holding portions 762a, 764a. With a bolt 78 screwed into a threaded hole 764b of the holding portion 764a of the second main frame 764 through the holding portion 762a of the first main frame 762, the first main frame 762 and the second main frame 764 can hold the handlebar 200 together to firmly mount the mounting frame 76 on the handlebar 200.
In conclusion, the accessories are around the frame member and firmly mounted on the handlebar. Besides, the coupling slots are longer than the sliding members, and the sliding members could be secured at any position within the coupling slots.
The description above is a few preferred embodiments of the present invention and the equivalence of the present invention is still in the scope of claim construction of the present invention.
