Structure of a spoke positioning pocket

Abstract

The rim spoke positioning pocket is a single metal plate placed in a cylindrical shape. One embodiment is coiled, and another embodiment is an expanded cylinder. A through hole is placed in the center of the positioning pocket, and the bottom has claws that are circular in shape and expandable outward. The inside surface corresponds to the claw shape to received a spoke tip connector, and the top of the positioning pocket is a straight opening. One side of the positioning pocket forms a connecting part by a coiled metal plate. The rim spoke positioning pocket for a bicycle or motorcycle can be made with simple steps and a low cost, which is better for mass production.

DETAILED DESCRIPTION OF THE INVENTION

The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

First, FIGS. 3, 4, 5 show the preferred embodiment of the structure of a spoke positioning pocket. The rim mentioned herein includes the rim for a bicycle or motorcycle. The positioning pocket 40 mentioned herein is used for the expanded tip 51 of the spoke 50, when the spoke 50 is placed inside the joint hole 61 of the rim 60.

The positioning pocket 40 disclosed in the present invention is a single metal plate coiled inside the cylinder. A through hole 41 is placed in the center of the positioning pocket, and the top end 42 of the positioning pocket is a straight opening. Its bottom has a claw 43 that is circular in shape and expands outwardly. The inside corresponds to the claw shape to form a spoke tip connector 44, and one side of the positioning pocket 40 forms a connecting part 45 formed by the coiled metal plate mentioned above.

The above embodiment has an inner groove edge 46 formed between the roots of the claws 43. The inner groove edge 46 disclosed in the present embodiment is circular in shape, and through the setting of the inner groove edge 46 to stress the connection at the root of the claws 43, so that when the positioning pocket 40 is coiled in a cylinder shape, the surface can be a smooth curve to prevent the corner from being folded.

As for the idea of the positioning pocket 40 mentioned above to be in the coiled shape, as shown in FIG. 6, the making of the positioning pocket 40 uses a long metal material 70 to form several rectangular chips 71 for a single positioning pocket 40 by the thrust method. All rectangular chips are connected to the disconnecting line 72 and inner groove edge 46 that separate the claws 43. By so doing, the rectangular chip 71 can be coiled to make the positioning pocket 40.

Through the above structure and design, the operation of the present invention can be explained.

As shown in FIG. 7, when the positioning pocket 40 is assembled, it is placed on the spoke 50, and the expanded tip 51 of the spoke is inserted into the joint hole 61 of the rim 60. The positioning pocket 40 is inserted into the joint hole 61 by one end that has claw 43 (as shown in FIG. 8). As shown in FIG. 9, the spoke 50 is pulled back to make sure that the expanded tip 51 is locked into the spoke tip connector 44 of the positioning pocket 40, and then the expanded tip 51 is tightened up. The expanded tip is screwed to the spoke. Now, the spoke 50 and the rim 60 are positioned.

As shown in FIG. 10, there is another embodiment of the rim spoke positioning pocket. The positioning pocket 40B is a single metal plate in cylindrical shape, and a through hole 41B is placed in the center of the positioning pocket 40B. The top 42B of the positioning pocket is a straight opening, and the bottom has several claws 43B that are in circular shapes and that expand outwardly. The inside corresponds to the claw shape to form a spoke tip connector 44B. The edge of the top of the positioning pocket can be a cone shape.

The positioning pocket 40B made of metal plate mentioned above is shown in FIG. 11, and it can be a base material for a circular metal plate 80. The circular metal plate 80 is placed between pre-designated male and female molds 81, 82, and by moving the male mold 81 toward the female mold 82 the positioning pocket is formed.
