Description

Hub

This creation relates to the field of collection of bicycle cables, and in particular to a hub.

As shown in Fig. 5, the bicycle 90 has a frame 97 on which a brake system and a shifting system are mounted.

The brake system referred to herein is generally composed of a two-bar cable 91, a two-handle handle 93 and a two-way clamp 94. One end of each brake cable 91 is connected to the brake handle 93, and the other end is combined with the brake clamp 94 to slow down or stop the bicycle 90, thereby ensuring the safety of driving.

The shifting system referred to herein includes a shifting cable 92, an operating member 95, and a transmission 96. The shift cable 92 is connected to the operating member 95 at one end and to the transmission 96 at the other end to change the ratio of the force applied during the pedaling to a high or low speed.

Whether the brake cable 91 or the shift cable 92 is used, most of the core wires are formed by passing one or more core wires. The core wire is made of metal and has a certain tension. The tube is usually made of plastic and has flexible properties.

In the figure, the tube of the brake cable 91 is attached to the frame 97 and is not movable, but will bend as the bicycle 90 turns. The greater the curvature, the greater the friction between the tube and the core wire, and the effect of the brake is very large.

Secondly, the frame 97 forms a through hole 98 that allows the shift cable 92 to pass through the through hole 98 and is partially hidden within the frame 97. However, the structural strength of the frame 97 is due to The hole 98 is weakened. In addition, the tube of the shift cable 92 is still bent during the turning of the bicycle 90, and the frictional force of the core wire is increased, which also affects the smoothness of the shifting.

Taiwan's new patent No. M487876 proposes a vehicular line converging structure that is suitable for use on the front of a bicycle. The front bowl has a bead bowl, the bead bowl protrudes from one ear, and more than one perforation is formed in the ear, which has a limit effect on the brake line passing through the perforation, but cannot effectively solve the disadvantage of the curved tube increasing the frictional force of the core. .

In addition, the creator of the case provided a hub that uses a rotatable structure to reduce the influence of the bending of the tube on the braking or shifting performance, and has the effect of collecting the wire, and applied for the patent of Taiwan's new type M508496.

However, the creators of this case are not complacent, and in the spirit of excellence, once again developed a related hub, the main purpose of which is to simplify the interlocking structure, which not only is simple to assemble, but also reduces production costs.

Due to the above object, the hub of the present invention comprises: an endless belt having two ends and an inner wall, the inner wall of the annulus being a substantially C-shaped open space, when the two ends of the ring are close to each other, The inner wall encloses an annular or O-shaped space; an interlocking assembly includes: a first engaging structure having a first ridge formed at one end of the endless belt, the first ridge having a first end face, first The end surface protrudes from a first caliper arm, the bottom of the first caliper arm forms a row of teeth; a second engagement structure has a second ridge portion disposed at the other end of the endless belt, and the second ridge portion has a second caliper arm and a tongue piece, the second caliper arm extends according to the curvature of the inner wall, and the top surface has a row of teeth that can engage the first caliper arm, the tongue piece is hollow, and a hole is formed around the wall surface of the hollow portion; A wire clamping member comprising: a head having a substantially C-shaped cavity; a neck having one end connected to the head; and an expanding portion integrally formed with the other end of the neck, the expanded portion being along a length of the neck The extended slot is divided into two parts for engaging the tongue around the wall surface of the hole, so that the neck of the wire holding member is rotatably connected to the tongue and is not easily detached.

Wherein, a side of each of the second caliper arms and the tongues facing the first engaging structure is regarded as a second end surface, and the second end faces are substantially flush. Additionally, the aperture is preferably conical and is located at the top of the tab.

In this way, the hub of the present invention reduces the structure of the second tongue piece, the drop part and the like than the Taiwanese new type M508496 patent, and the interlocking structure can naturally be simplified, which is not only simple to assemble but also reduces the production cost.

Then, based on the detailed description of the related embodiments, the techniques, means and functions employed are described. It is believed that the above objects, structures and features of the present invention can be obtained from a deep and specific understanding.

Figure 4 is a schematic illustration of the hub used in the frame.

Figure 5 is a schematic view of a conventional bicycle.

As shown in Figures 1-3, a preferred embodiment of the hub 10 is constructed by adding an interlocking assembly 16 and a wire holder 18 to an endless belt 12.

In the figure, the annulus 12 has two ends, which have an inner wall 11 and enclose an approximately C-shaped open space (as shown in Fig. 2). When the two ends of the annulus 12 are close to each other, the inner wall 11 encloses an annular or O-shaped space (as shown in Fig. 3).

The interlocking assembly 16 includes a first engagement structure 22 and a second engagement structure 34 that are located at both ends of the annulus 12. When the inner wall 11 of the annulus 12 holds a C-shaped space (as in Fig. 2), the first and second engagement structures 22, 34 are separated. When the inner wall 11 of the endless belt 12 maintains an O-shaped space (as shown in Fig. 3), the first and second engaging structures 22, 34 are engaged with each other and are not easily separated.

Specifically, the first engaging structure 22 includes a first caliper arm 20 and a first ridge portion 23. The first raised portion 23 is located at one end of the endless belt 12 and has a thickness greater than the thickness of the endless belt 12, and the two are designed to be integrated. The first ridge 23 is similar to a hollow frame, which is defined as a first end face 24 facing one side of the second engagement structure 34 and projecting a first curvature arm 20 of a certain curvature at the first end face 24. The first caliper arm 20 is integrally formed with the first ridge portion 23, and a row of teeth 21 is formed at the bottom.

The second engaging structure 34 includes a second caliper arm 30, a tongue 32 and a second ridge 33. The second raised portion 33 is located at the other end of the endless belt 12, and is integrally formed with the endless belt 12, and extends the second clamp arm 30 by the inner wall 11 at a joint portion of the second raised portion 33 and the endless belt 12. The second caliper arm 30 is integrally formed with the second ridge portion 33, the top surface of which forms another row of teeth 31, and the side facing the first engagement structure 22 is the second end surface 37. The tongue piece 32 is integrally formed with the top end of the second raised portion 33, and is substantially parallel to the second forceps arm 30, and the three are enclosed by an engagement cavity 35. The tab 32 may be hollowed out, forming a hole 14 around the wall of the hollow portion, and the side of the tab 32 facing the first engaging structure 22 as the second end face 37. Wherein, the second second end faces 37 are substantially flush, and the holes 14 are preferably conical, which are located at the top of the tongue 32.

When the first and second ridges 23, 33 move toward each other, the first caliper arm 20 penetrates into the cavity 35, and the tongue 32 and the second caliper arm 30 are located above and below the first caliper arm 20, and the second row The teeth 21, 31 are engaged with each other until the first and second end faces 24, 37 are close to each other or resisted, so that the inner wall 11 of the annulus 12 maintains an O-shaped space which is tightened to the frame 97 (as shown in Fig. 4). Not easy to get rid of.

Next, a wire holder 18 is seen which includes a head 40, a neck 41 and an expansion 43. The head 40 is generally C-shaped and has a cavity 42 and an opening 45 having a diameter greater than the opening 45. The neck 41 has a substantially cylindrical shape, one end of which is coupled to the head 40, and the other end is connected to the expansion portion 43, and the three are designed to be integrated. The flared portion 43 is substantially hemispherical, and a slit 44 deeper from the center of the spherical surface toward the head 40 to the neck 41 allows the flared portion 43 to move in a closed position and a home position.

In the closed position, the flared portion 43 is reduced in volume and can pass through the aperture 14 of the tab 32. In the original position, the flared portion 43 returns to its original volume and catches the tab 32 around the wall surface of the aperture 14, preventing the wire holder 18 from leaving the tab 32, but the neck 41 can be rotated relative to the tab 32 by the neck 41.

In some embodiments, the flared portion 43 is generally conical, and the neck 41 can be a tapered cylinder.

It will be readily understood from FIG. 4 that the opening 45 of the head 40 is less than a diameter of a wire 50 for braking or shifting, the cavity 42 having a diameter substantially equal to the diameter of the wire 50.

When the wire 50 enters the cavity 42 through the opening, the head 40 has a biasing force to return to the original state, and the tube 52 of the wire 50 and the core wire 54 have a positioning effect similar to that of the core wire 54 and have a collecting effect.

Next, the wire holding member 18 is rotated, and even if the wire 50 is swung relative to the frame 97, it is less likely to be bent or folded, so that the core wire 54 still maintains a good linear motion effect.
