Description

Bicycle fork mount

This creation relates to the transportation technology of vehicles, and in particular to a mount that facilitates the carrying and transporting of bicycles by vehicles.

Some vehicles will have a carrying frame at the top. This carrying frame has a crossbar or related components for series use. The two ends are respectively an externally threaded section for locking the corresponding nut through a coupling. The device forms a clamping action on the front or rear fork of the bicycle, facilitating the vehicle to carry the bicycle to the destination.

Conventional coupling devices have been found in U.S. Patent No. 6,036,069. The coupling device has a hollow cross member and two side members. The cross member has a fastening device therein, and the fastening device partially exposes the outside of the cross member to clamp the front fork of the bicycle. Each of the side members is vertically connected to the end of the cross member, the free end of which forms a substantially U-shaped notch sufficient to accommodate the threaded section of the crossbar.

However, the side members and the cross members are coupled by means of welding, and the joints of the two are not only susceptible to rust or cracking, but also impair the structural characteristics in addition to affecting the appearance. Secondly, the assembly of the carrying frame must repeatedly perform the nut removal and locking action, which is very inconvenient.

Therefore, how to make the bicycle easily placed on the roof of the car becomes an urgent problem to be solved in this creation.

In view of this, the creator explored the problems of prior art in depth, and after years of experience in R&D and manufacturing of related industries, actively sought solutions, and finally succeeded in developing a new mount to improve the problem of custom creation. .

The purpose of this creation is to use a one-piece molding technology, combined with a combination of multiple components, not only easy to assemble or disassemble, but also reduce the probability of corrosion, thus extending the service life. limit.

Due to the above object, the seat of the present invention comprises: a body, which is connected with two longitudinal members in a transverse member, so that the seat body has a bifurcated contour, and each longitudinal member forms a round receiving hole with a vehicle Connected and detachable; two side members, each of which has a flange formed on the periphery thereof, the flanges are provided with an insertion portion and an exposed portion, and a hole is formed in the center of the side member, and the two ends of the hole are respectively exposed through the insertion portion The end face of the section; and a quick release.

When the flange is in contact with the wall surface of the receiving hole of the longitudinal member, the exposed portion is exposed outside the longitudinal member, and the insertion portion passes through the corresponding receiving hole, so that the holes of the two side members are opposite to each other for quick release, allowing quick release Reciprocating between a releasable position and a clamped position.

When the quick release is moved to the release position, the exposed portions of the two side members carry the corresponding fork ends of the bicycle. When the quick release comes to the clamping position, the fork end is clamped with the flange to fix the bicycle to a vehicle and can be removed.

Thus, the longitudinal members are integrally formed beside the cross members such that the bifurcated seat has a lower corrosion rate than the welded coupling device. In particular, the combination of the seat and the side parts and the quick release makes the clamping or unloading movement easier and less time consuming.

Hereinafter, the purpose, structure and characteristics of the related embodiments will be described in detail based on the drawings, and it is believed that the techniques, means and functions adopted by the present invention can be obtained from an in-depth and specific understanding.

Figure 1 is an exploded perspective view of a preferred embodiment of the present mounting.

Figure 2 is a combined perspective view of the mount.

Figure 3 is a cross-sectional view showing the first use state of the mount.

Figure 4 is a schematic view of the second use state of the mount.

Referring to Figures 1 and 2, the specific configuration of the mount 10 is illustrated, including: a body 20 and two side members 30, which are assembled together by a quick release 12.

The quick release 12 in the figure has a screw 14 for a pair of compression springs 18 to be placed over the screw 14. The screw 14 has two thread segments 16, each of which is formed at a respective end of the screw 14. One of the thread segments 16 is screwed to a detachable nut 11. The other threaded segment 16 is maintained in a threaded relationship with a short rod 15 by a movable sleeve 13. The movable sleeve 13 is hollow inside, one end of which is opposite to the corresponding compression spring 18, the other end accommodates a follower 17, and a concave curved surface 42 is formed at a portion of the follower 17 exposed to the movable sleeve 13, and the curved surface 42 is facing the second The outer edge of the pivot 44 of the shape is symmetric. The pivots 44 are integrally formed with a handle 19, each of which has an eccentric annular profile for receiving at the corresponding end of the stub 15 and coupling the structure of the stub 15 through the screw 14 to prevent the stub 15 from leaving the pivot Ear 44.

The structure of the quick release 12 is not limited to the structure disclosed in the drawings. The reciprocating movement of the handle 19 in the loose and clamped position belongs to the scope of the quick release 12 of the present invention.

The release position herein refers to the position where the handle 19 is located when the distance between the nut 11 and the pivoting arm 44 is increased.

The clamping position herein refers to the position where the handle 19 is located when the distance between the nut 11 and the pivoting arm 44 is shortened.

Next, it is seen that the seat body 20 has a cross member 22 which is a rectangular sheet material which is bent over a longitudinal member 24 on both sides so that the seat body 20 has a bifurcated contour. These longitudinal members 24 are symmetrical in shape and are formed by a continuous bending means to form an upright portion 21, a slanted shoulder portion 25 and a joint portion 27.

The two upright portions 21 are bent on the short sides of the rectangular plate material (that is, the two sides of the cross member 22), and are preferably kept parallel to each other. A circular receiving hole 23 is formed in the center of each of the upright portions 21. Each of the inclined shoulder portions 25 is coupled to the lower side of the upright portion 21, and the other side is extended outwardly from the angle to be integrated with the corresponding joint portion 27, so that the two longitudinally extending joint portions 27 are spaced apart from each other by a distance greater than the distance between the two upright portions 21. . Further, each of the joint portions 27 is formed with a groove 28 on the side so that the joint portion 27 has a hook-like profile and is detachable by being assembled to the vehicle.

Each of the side members 30 is substantially T-shaped, and a flange 32 is formed on the periphery thereof. The flanges 32 are respectively an insertion portion 34 and an exposed portion 36, and a surface is formed between the end surface of the insertion portion 34 and the end surface of the exposed portion 36. Hole 31. The insertion portion 34 has a cylindrical shape, and its circumferential surface forms a plurality of stripes 38 arranged in a horizontal strip.

During assembly, each side member 30 passes through the corresponding receiving hole 23 with the insertion portion 34 until the flange 32 abuts against the wall surface of the longitudinal member 24 around the receiving hole 23, allowing one The inner tube 46 is inserted into the hole 31 of the two side members 30. At this moment, the groove 38 of the insertion portion 34 forms a frictional relationship with the wall surface of the accommodating hole 23, and the support exposed portion 36 is exposed outside the longitudinal member 24.

The quick release 12 removes the nut 11 and the corresponding compression spring 18, and the screw 14 passes through the holes 31 of the two side members 30 opposite to each other, and then the nut 11 and the compression spring 18 are returned to the original position to complete the seat. 20 assembly work with the side members 30.

When the handle is forced to the release position, the nut 11 is remote from the pivot 44, facilitating the bicycle front fork 40 to straddle the corresponding exposed portion 36, similar to the hook end 47 of the joint 27. When the handle 19 is returned to the clamped position, the nut 11 is reduced in distance from the pivoting arm 44 such that the nut 11 cooperates with the movable sleeve 13 to exert a clamping force on the front fork 40, as shown in FIG.

In the figure, a partial edge around the pivot 44 touches the curved surface 42 of the follower 17. Since the distance from the center point of the short bar 15 to the edge of the pivot 44 is inconsistent, the pivot 44 moves eccentrically with the swing of the handle 19, and the short bar 15 and the follower 17 are separated from each other, and the screw 14 is driven by the screw 14 together with the screw. The caps 11 move together toward the handle 19. Conversely, the handle 19 comes from the clamped position to the release position, and the nut 11 and the movable sleeve 13 are pushed away by the compression spring 18 to facilitate the removal of the bicycle from the vehicle.

The inner tube 46 supports the side member 30 around the periphery of the screw 14, and the end surface of the inner tube 46 is resisted by the compression spring 18. If necessary, the wall thickness of the side member 30 can be increased such that the diameter of the hole 31 is substantially equal to the diameter or width of the screw 14, so that the compression spring 18 abuts against the thickened end surface of the side member 30 to replace the inner tube 46.

It should be noted that the front fork 40 of the present embodiment belongs to a standard part, a similarly constructed front fork 40, and other types.

The difference between the front fork 40 and the upper embodiment shown in FIG. 4 is that the front end of the front fork 40 forms an annular joint end 48, which is respectively adjacent to the corresponding exposed portion 36 of the side member 30, and is fastened and disassembled 12 The nut 11 is clamped to the movable sleeve 13 so that the joint end 48 is fitted over the outside of the screw 14 without being easily detached.

At this moment, as long as the groove 28 of the two joint portion 27 is aligned with a cross bar 52, the front fork 40 can be coupled with the carrier carrier 50 of the joint rail 52 by a conventional screw locking method.

The above embodiments are merely illustrative of the present invention and are not intended to limit the creation. Familiar with this skill Various changes, modifications, and applications derived from the above-described embodiments are within the scope of the present invention.
