Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a bicycle carrier, and more specifically, the carrier can be fixed to either the front fork or the back fork of a bicycle frame, and is compatible with back forks of various angles of inclination, and can be attached to clothes or side backs. The present invention relates to a vehicle that can effectively prevent wheels from coming into contact with spokes of a wheel.

[Conventional technology]

As a bicycle carrier mounting device that allows carriers of the same standard to be mounted on frames with various backhawk angles, the
The one shown in Publication No. 14151 has been proposed.
This involves tightening and fixing one end of the connecting fitting to the cantilever brake pedestal provided on the fork so that it can move up and down, and attaching the tightening fitting to the other end of the connecting fitting so that it can slide. The connecting fitting and the upper end portion of the carrier leg are fastened and fixed together through the connecting fitting and the upper end portion of the carrier foot.

[Problems that the idea should solve]

According to the conventional bicycle carrier mounting device described above, if the bicycle has a cantilever type brake, even if the angle of inclination of the back hawk is different, the position of the fastening metal fitting with respect to the connecting metal fitting can be adjusted. This makes it possible to install carriers of the same standard. however,
Most bicycles use so-called caliper brakes, and cantilever type brakes are rarely used, so the scope of application of the above conventional example is extremely narrow. Since the backhawk of a bicycle equipped with a normal caliper brake does not have the cantilever brake pedestal required for the conventional mounting device described above, the mounting structure of the conventional example described above can be adopted as is for a bicycle equipped with a caliper brake. This is because it is not possible. Therefore, the object of this invention is to provide a bicycle carrier that can all be attached to a bicycle according to the same standard.

[Means adopted to achieve the purpose]

In order to achieve the above object, the bicycle carrier of the present invention includes the following means. In other words, a carrier frame for carrying luggage,
A pair of left and right carrier legs that hang down from both side frames of the carrier frame and whose lower ends are connected to the rear end plate or hawk end of the bicycle frame, and are each fixed in a substantially horizontal direction at the vertical midpoint of the pair of left and right carrier legs. a support arm that is engaged with the guide rail so that it can be expanded and contracted in the direction toward the backhawk or front fork, and a support arm that is pivotally attached to the tip of the support arm and that and a clamp band that can hold the middle proper portion of the belt.

[Functions and effects of the idea]

The means for connecting the supporting arm to the back hawk or front hawk, which is attached to the carrier leg in a telescopically adjustable manner, is a clamp band that holds and tightens the hawk, so the supporting arm can be connected to any device in the longitudinal direction of the hawk. be able to. Further, since the length of the support arm from the carrier leg can be adjusted, the angle of the carrier can be adjusted as desired while reliably fixing the carrier. Furthermore, although the angle of inclination of the back hawk and the angle of inclination of the front hawk are different, the bicycle carrier of the present invention allows the length of the supporting arm to be fixed to the hawk to be adjusted, so that the length of the support arm from the carrier leg to the hawk can be adjusted. If you adjust the length of the support arm to correspond to the horizontal distance, whether it is a back hawk or a front hawk,
Identical carriers can be conveniently and securely mounted with their carrier frames horizontal. Additionally, in the present invention, the position of the carrier is determined by providing guide rails at the intermediate portions of the left and right carrier legs, and by connecting the tip of the extendable supporting arm to the hawk. , and since all bicycles necessarily have a front fork and a back fork, the bicycle carrier of the present invention can be conveniently attached to all bicycles as either a front carrier or a rear carrier. be able to. In addition, guide rails facing approximately horizontally are attached to the left and right carrier feet, which are positioned to sandwich the wheel from both sides.This guide rail prevents occupants' clothing and camping side bags from getting into the spokes of the wheel. It plays the role of a guard that effectively blocks the attack. As a result, the bicycle carrier of the present invention greatly contributes to improved safety.

[Explanation of Examples]

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an overall perspective view of an embodiment of the present invention. A carrier frame 1 on which cargo is placed has a substantially oval outer frame in which parallel side frame members 2, 2 are connected by front and rear curved portions 3, 4, and a space between the parallel side frame members 2, 2. It consists of two reinforcing rods 5, 5 connected in a spanning manner and an inverted U-shaped load holding member 3a extending upward from the front curved portion 3, and the pipe or rod material can be bent or welded. It is made by doing. A pair of left and right carrier feet 6,6
is formed into a V-shape when viewed from the side, and its upper end portions 7, 7 are fixed to the lower surfaces of both side frame members 2, 2 of the carrier frame 1, and a lug piece 12 with a through hole 11 is attached to the lower end portion 8. It is designed to be fixed to a mounting hole in a rear end plate 10 of a bicycle frame using bolts 9. In this way, the basic shape of the bicycle carrier of the present invention is completed, which consists of the carrier frame 1 and the carrier legs 6, 6. However, the carrier frame has a seat lug or a mounting piece for the carrier brake mounting shaft, as seen in conventional carriers. is omitted. The above basic shape is
Various design changes are possible; for example, the carrier frame 1 may have a flat plate part formed by press working a steel plate, and the carrier legs 6, 6 are not limited to the V-shape in side view as shown in the example, but may be the same on the left and right sides. It may also be formed from a book bar. In the vertical middle part of the carrier legs 6, 6,
Guide rail 1 so that it faces horizontally in the front-rear direction.
3 and 13 are attached. This guide rail 13
As shown in detail in FIG. 2 and FIG.
A, 14a are formed so as to hold one side thereof, and both ends form a V shape in the carrier legs 6, 6 and are fixed to respective bars located in the front and rear. In this way, by sliding the support arms 14, 14 on the guide rail 13 in the front-rear direction, the effective length of their forward protrusion can be adjusted. The effective protruding length of the support arms 14, 14 can be adjusted by, for example, elongated holes 15, 1 provided in the guide rail 13.
5, screw the bolts 16, 16 toward the screw holes drilled on the guide rail side side surfaces of the bases of the support arms 14, 14, and tighten the bolts 16, 16 to fix the support arms, then loosen them. As a result, the fixation is released and the support arm moves to the guide rails 13, 13.
All you have to do is make it slide on the top. In the illustrated example, the side bag holders 17, 17 are removably attached via ears 18, 18 provided on the guide rail and attachment ears 12a provided at the lower ends of the carrier legs 6, 6. . Clamp bands 19, 19 capable of holding the back hawk and front hawk are attached to the tips of the support arms 14, 14. The clamp band 19 has through-holes formed in the ears 20, 20 provided at the abutting ends thereof, and also through-holes are formed at the ends of the support arms 14, 14, and bolts and nuts are inserted into these through-holes. It is attached by assembling the screwing means 21, 21 according to the above. When the screwing means is tightened, the inner diameter of the clamp bands 19, 19 is reduced and the hawk is tightened, and the supporting arms 13, 13 and the hawk are fixed to each other. On the other hand, when the screwing means is loosened,
The inner diameters of the clamp bands 19, 19 expand to release the above fixed state, and the clamp bands 19, 19 become pivotable around the bolts of the screwing means. Next, the operation of this embodiment will be explained. The shape of bicycle frames, especially the angle of inclination of the backhawk, differs between manufacturers and countries. Furthermore, it is well known that the inclination of the backhawk with respect to the vertical axis and the inclination of the front fork with respect to the vertical axis are different from each other. Furthermore, in bicycle carriers, there are various methods for fixing the front portion of the carrier frame to the frame. For example, one that fixes a branch extending from the front of the carrier frame to the caliper brake mounting shaft, one that fixes a stay integral with the carrier frame to a cantilever brake pedestal,
Or something that is fixed to the seat rug.
In this case, for example, a carrier that is fixed to a cantilever brake pedestal is not compatible with a bicycle that does not have a cantilever brake. It can only be installed by hand. In contrast, the bicycle carrier of the present invention can be attached to all bicycles, regardless of the detailed configuration of the bicycle frame. This is because the carrier of the present invention uses a clamp band at the tip of the support arm that is telescopically attached to the carrier leg to hold and fix the back fork or front fork that all bicycle frames have. Because there is. Furthermore, as shown in FIG. 5, even if the inclination of the back hawk B varies, the support arms 13 and 1 can be adjusted according to the horizontal distance from the carrier foot 6 to the back hawk.
By adjusting the length of the carrier frame 1, the carrier frame 1 can be conveniently installed horizontally. Similarly, the same carrier can be attached to the front fork at the front of the bicycle, as shown in FIG. Furthermore, as shown in FIG. 6, the guardrails 13 and support arms 14 are positioned so as to sandwich the wheels from both sides, so they act as guards to prevent the occupant's clothes and side bags from accidentally getting into the spokes of the wheels. It also has functions that improve driving safety. It goes without saying that the scope of the present invention is not limited to the embodiments described above. For example, in the illustrated example, a side bag holder is attached to the side of the carrier leg, making it suitable for so-called camping vehicles, but whether or not to attach the side bag holder is merely a matter of choice. Further, the specific shapes of the guide rail and the support arm that slidably engage with the guide rail can also be modified in various designs.

【summary】

As explained above, the bicycle carrier of the present invention can be conveniently attached to any bicycle in a single shape, and the cost reduction effect by shifting to mass production of one product is extremely significant.
