Disc Brake Locking Assembly

The present invention concerns a disc brake locking assembly. More particularly, said disc brake locking assembly involves the employment of a locking pin that is capable of sensing the presence of a ventilation opening, thereby eliminating the need of finding a ventilation opening on the disc brake and aligning it manually with the locking pin of a disc brake lock.

In light of the fact that conventional configurations of disc brake locks are subject to drawbacks, such as being inconvenient to deploy and requiring complicated steps during the manufacturing process, the inventor arrives at the present invention, which concerns a disc brake locking assembly. Accordingly, the following merits are realized with the design improvement pertaining to the present invention:

1. The moving piece pertaining to the present invention moves accurately and reliably, because the cross section thereof is comparatively large.

2. The locking rod pertaining to the present invention cannot be damaged readily, because the controlling cotter is controlled indirectly by the lock cylinder and the locking rod, in turn, is also indirectly controlled by the controlling cotter; furthermore, said locking rod is actuated indirectly by the moving piece.

3. The bottom of the opening slot is equipped with a rubber cushion, so that the bottom of the opening slot cannot be damaged accidently by the braking disc during the deployment of the disc brake locking assembly.

4. The locking operation pertaining to the present invention can be performed rapidly, because said disc brake locking assembly involves the employment of a locking rod that is capable of sensing the presence of a ventilation opening when the opening slot is inserted into the braking disc and the locking rod comes into contact with said braking disc, thereby eliminating the need of finding a ventilation opening on the disc brake and aligning it manually with the locking pin of a disc brake lock.

5. The left side of the lock body pertaining to the present invention is equipped with a lock hole, which is a through hole, thereby allowing said lock hole to be clean and dirt to come out.

As shown in FIGS. 1 and 2, the disc brake locking assembly pertaining to the present invention consists of components, which include a lock body 12, moving piece 13, locking rod 14, controlling cotter 15 and rubber cushion 17. An opening slot or slot-like opening 18 with an opening facing upward is located at an appropriate location on the left side of said lock body 12. Accordingly, said lock body 12 exhibits a U-shaped configuration. The bottom of said opening slot 18 is equipped with a rectangular slot 19, and a rubber cushion 17 is placed inside said rectangular slot 19. As shown in FIG. 2, the left and right sides of said opening slot 18 possess trapezoidal slots 20 and 21 respectively at corresponding positions. As shown in FIG. 3, the trapezoidal slots 20 and 21 are equipped with rubber pieces 22 and 23 respectively, so that damage caused by the braking disc striking on said disc brake locking assembly can be prevented. Said disc brake locking assembly also possesses a vertical cotter hole 24 at a specific location on the right upper part of said lock body 12, and a FIG. 8 slot or receiving aperture 25 with a certain specified depth on the upper right side wall of said lock body 12, as shown in FIGS. 3 and 4. In addition, an axial through hole 24 is made at a specific location on the FIG. 8 slot 25 in such a manner that said through hole 26 is connected to said vertical hole 24 and penetrates into said opening slot 18. An interior lock hole 27 is made on the right side wall of the left side of said lock body 12 at a specific location corresponding to the through hole 26. Moreover, a lock cylinder hole 28 is made below the FIG. 8 slot 25, and the front of said lock cylinder hole 28 is connected to said vertical hole 24. A first spring 29 and a controlling cotter 15 equipped with a catch 30 on the top thereof and a lock tongue receiving slot 31 at the lower part thereof are placed into said vertical hole 24 in said order. The moving piece 13, which exhibits a FIG. 8 shape having an upper and lower portion, fits snugly into said FIG. 8 slot 25. The lower part of said moving piece 13 is elliptical and is equipped with a round slot 32 on the left side, while the upper part of said moving piece 13 is round and is equipped with a round slot or lateral hole 34. A third spring 33 is placed inside said round slot 32, while a vertical round slot or hole 35 is made at a specific location on the top of said moving piece 13 and connected to said round slot 34. The underside of one end of said locking rod 14 is equipped with a catch section 36 at a specified location, and the upper side of the other end is equipped with a slot 37. The end of said locking rod 14, possessing said catch section 36, is round, while the other end has a flat surface. A second spring 38 and said locking rod 14 are placed inside the round slot 34 on the upper left side of said moving piece 13 in said order, and a second pin 39 is then inserted into said slot 37 on the upper part of said locking rod 14 through said round slot 35, so that said locking rod 14 is bound to said moving piece 13. The waist area of said moving piece 13 is equipped with a slot 40. The assembled moving piece 13 containing said locking rod 14 is then inserted into said FIG. 8 slot 25. Said operation allows said locking rod 14 to be inserted snugly into the through hole 26 and the rounded end of said locking rod 14 to protrude slightly into said opening slot 18, so that said locking rod 14 can come into contact with the braking disc 43. Said lock body 12 is equipped with a pin 41, with one end thereof extending inside said lock body 12 and joining the slot 40 located on said moving piece 13. The configuration allows said pin 41 to control the extent said moving piece 13 can move back and forth and to govern the position thereof precisely. The front of said lock cylinder 16 possesses a rectangular tongue 42, and the installation of said lock cylinder 16 into said lock hole 28 causes the rectangular tongue 42 at the front of said lock cylinder 16 to be inserted into the vertical hole 24 and rest inside the slot 31 of said controlling cotter 15. Accordingly, the up-down movement of said controlling cotter is governed by the turning of said lock cylinder either for locking or unlocking.

The locking operation of said disc brake locking assembly is described below. As shown in FIGS. 3 and 4, when the opening slot 18 pertaining to said disc brake locking assembly is inserted into the braking disc 43 (see FIG. 3), said braking disc 43 comes into contact with the rounded end of said locking rod 14, causing said locking rod 14 to be pushed into the round slot 34 of the moving piece 13, opposing said spring 38. When the round face of said locking rod 14 comes into contact with a ventilation opening 44 on the braking disc 43, the restitution force of said spring 38 causes the round face of said locking rod 14 to be inserted into said ventilation opening on said braking disc 43. Next, the moving piece 13 in the lock body 12 is pushed forward, causing said locking rod 14 to be inserted into the lock hole 27 after penetrating through the ventilation opening 44 on the braking disc 43. Meanwhile, the restitution force of the spring 29 causes the controlling cotter 15 to move upward, thereby allowing the catch 30 on top of said controlling cotter 15 to bind tightly onto the catch section 36 on said locking rod 14, and completing the locking operation. Said disc brake locking assembly can be unlocked by turning the lock cylinder 16 to the opening position. Said action changes the orientation of the rectangular piece 42 at the front of said lock cylinder 16, as shown in FIG. 3. As a result, said controlling cotter 15 is caused to move downward, thereby releasing the catch 30 on top of said controlling cotter 15 from the catch section 36 and freeing said locking rod 14. The restitution force of the spring 33 causes the moving piece 13 to move away from the lock body 12, which allows said locking rod 14 to return to said through hole 26, with the round face situating in the opening slot 18.
