Description

[Detailed Description of the Invention] This invention relates to a bicycle carrier, and more particularly, to a bicycle carrier that can be attached and detached from a seat pillar or a saddle body very easily as appropriate.

For example, a so-called mountain bike, which is used for off-road riding and mountain climbing, as shown in Fig. 1, has its crankshaft a positioned at a position different from that of a regular bicycle so that it can run smoothly over uneven terrain. In addition to using a sturdy frame b that is set slightly higher, it is equipped with thick tires c with a deep groove-like tread pattern so that it can run on all kinds of areas such as sand, mud, and rocky terrain without slipping. In the drive system, the gear ratios of the front and rear gears are widened to allow for easy climbing of steep slopes, and accessories such as mudguards and carriers that are not directly related to the driving function are In order to maintain safety under harsh driving conditions and reduce the weight of the vehicle, it is normally not installed.

However, even such bicycles are sometimes used for traveling on flat land like regular bicycles, and in such cases, even if you try to carry small luggage, there is no place to put it, which can be a problem. There is. Also, even if you try to attach a commercially available bicycle carrier, it will not be easy because the frame structure is not designed to allow such a commercially available carrier to be attached.

On the other hand, when riding a mountain bike like this, you may be riding on a steep slope. For example, when riding down a steep slope, the rider must shift his weight to avoid falling forward. It is dangerous if you do not move the center of gravity of the entire bicycle to the rear as much as possible. In such cases, since the front-to-back length of the saddle is roughly the same as that of a normal bicycle, it is unavoidable to lift the buttocks off the saddle and move the raised buttocks or other important parts to the unsupported space behind the saddle. Yes, this is also dangerous. In addition, even if you create a saddle with a long front-to-back saddle top to prevent these dangers, it will not look good, it will require manufacturing a small number of specially shaped parts, which will increase costs, and the weight of the vehicle will increase. This problem arises, and it cannot be said to be a preferable solution.

This invention was devised under the above circumstances, and its purpose is to be able to easily attach it as needed to secure a place to put luggage, and to use it as an auxiliary saddle that extends behind the saddle. It is an object of the present invention to provide a bicycle carrier which can function to ensure safety when traveling on steep slopes as described above.

In order to achieve this purpose, the bicycle carrier of the present invention employs the following configuration.

That is, a pair of left and right hooks are located below the saddle top and can be engaged near the rear ends of a pair of left and right base rods supported by clamps at the upper end of the seat pillar;
The present invention has a loading platform part continuous at approximately the same height as the upper surface of the saddle top, a carrier stay extending from the loading platform part, and a receiving section provided at the end of the carrier stay and received by the seat pillar.

This bicycle carrier can be easily installed by simply hooking the pair of left and right hook portions onto the base rod of the saddle and allowing the receiving portion of the end portion of the carrier stay to be received by the seat pillar. For example, if the receiving portion is formed as a member that simply contacts the rear surface of the seat pillar, it can be easily attached and removed without using any special tools or attachment members. Moreover, since the loading platform extends in a continuous direction from the upper surface of the saddle top in the attached state, this loading platform can also function as an auxiliary saddle extending behind the original saddle top, for example. Even when going down a steep hill on a mountain bike, by sliding your buttocks from the saddle top to the carrier's cargo bed, you can safely shift the center of gravity of the vehicle backwards without lifting your buttocks. .

Embodiments of the present invention will be specifically described below with reference to the drawings.

As shown in FIG. 2, the bicycle carrier 1 of this example can be formed by bending or welding a metal pipe or metal rod made of steel or light alloy, and has a pair of left and right openings. Hook portions 2, 2, a pair of left and right loading platform portions 3, 3 that extend an appropriate length approximately horizontally rearward in a continuous manner from the hook portions 2, 2 while slightly expanding, and a rear end portion 3a of the loading platform portions 3, 3. , 3a, and a pair of left and right carrier stays 4, 4 which extend diagonally forward downward and then horizontally forward, and the front ends 4a, 4a of these carrier stays 4, 4 are welded to each other, and the seat It has a receiving support portion 6 made of a plate material bent and formed so as to be able to hold the rear surface 5a of the pillar 5. A horizontal bar 7 is welded and fixed near the rear ends of the carrier parts 3, 3 so as to span between the carrier parts 3, 3, thereby increasing the rigidity of the carrier 1 as a whole.

On the other hand, the bicycle saddle 8 to which the carrier 1 is attached includes a seat pillar 5 that is inserted into and fixed to the upper end 10a of the pipe 10 of the bicycle frame 9, as shown in FIGS. 3 and 4.
It is composed of a saddle body 12 supported by a clamp 11 provided on the upper part of the seat pillar 5. The saddle body 12 has a saddle top 13 formed in a shape to conveniently receive the buttocks of a rider, and both front and rear ends 14a and 14b are fixed to the lower surface of the saddle top 13 so as to extend from the front to the rear. It has a pair of left and right base rods 14, 14. The saddle body 12 is constructed by clamping and fixing the intermediate portions of the base rods 14, 14 to the clamp 11.
It is attached to the seat pillar 5. As shown in FIGS. 3 and 4, the intermediate portions of the base rods 14, 14 have parallel portions 14c, 14c.
is provided, and when the clamping force is loosened by turning the screw 15 of the clamp 11, this clamp 11
The parallel portions 14c, 14c slide back and forth against the saddle body 12, so that the position of the saddle body 12 relative to the seat pillar 5 in the front and back direction can be adjusted. Also, since the intermediate portions of the base rods 14, 14, which have lengths in the front and rear, are supported by the seat pillar 5, the base rods 14,
14 is also slightly elastically bent and deformed by the weight of the rider, and also serves as a cushion spring.

As clearly shown in FIG. 4, the carrier 1 of this example has a pair of left and right hook portions 2, 2 attached to the rear end portions of the base rods 14, 14 of the saddle body 12.
In addition to hooking it on 4b and 14b,
As clearly shown in Figure 2, the receiving branch 6
It can be attached to the existing saddle 8 very easily by simply holding the rear surface 5a of the seat pillar 5, without requiring any special tools or attachment members. can. To remove this carrier 1, lift the rear part of the carrier 1, separate the receiving part 6 and the seat pillar 5, and then remove the hook parts 2, 2 and the base rod 1.
All you have to do is solve the multiplication with 4 and 14. Since the hook parts 2, 2 can be elastically moved toward and away from each other, it is very easy to disengage them from the base rods 14, 14.

In addition, if a downward load is applied to the loading platform 3 in the installed state, there is a concern that the supported branch 6 may slide downward on the surface of the seat pillar 5, but in this case, as shown in FIG. As shown in FIG. 2, a large diameter portion 17 is provided by fixing a clamp band 16 to an appropriate portion of the seat pillar 5, and the receiving branch 6 is hooked to this large diameter portion 17 to prevent it from sliding downward. Just do it like this. However, if the amount of protrusion of the seat pillar 5 from the upper end of the vertical pipe 10 is adjusted so that the upper end 10a of the vertical pipe 10 is properly caught on the receiving support 6, it is not necessary to provide the large diameter portion 17 as described above. will disappear.

As shown in FIG.
Since the loading platform parts 3 and 3 continue rearward from the rear end of the saddle top 13 at approximately the same height,
The loading platform portions 3, 3 can also be used as an auxiliary saddle continuous to the rear of the saddle top 13.
For example, when riding a mountain bike, when going down a steep slope, the buttocks are pushed to the top of the saddle.
Since the center of gravity of the bicycle can be adjusted by sliding it directly onto the loading platform parts 3, 3, which serve as auxiliary saddles, it is very convenient for riding safely on hills.

In addition, in this example, as clearly shown in FIG.
A parallelogram-shaped space 18 in side view surrounded by the carrier stays 4, 4 bent in a letter shape and the saddle 8
As shown in FIG. 6, this space 18 can be used to house and hold the bag 19. As shown in FIG. 7, for example, this bag 19 has a main body formed into a shape that can be stored in the space 18, and a pair of bags sewn onto the upper surface of the bag 19 so as to overhang from side to side. For example, the ear-shaped attachment bands 20, 20 are attached to surface fasteners 21, 21.
After storing the main body in the space 18, attach the mounting band 2 while wrapping the cargo platform parts 3, 3.
0, 20 can be attached to the side surface and attached to the carrier 1. In addition, if the mounting bands 20, 20 are formed of a cushioning member that connects left and right on the upper surface of the bag body and is wide in the front and back direction, when the bag 20 is installed, the cushion will be attached to the cargo platform 3 of the carrier 1. This makes it very convenient as a loading platform that should function as an auxiliary saddle.

Incidentally, it goes without saying that the present invention is not limited to the embodiments described above.

For example, as shown in FIG. 5, the receiving branch 6 whose end portion of the carrier stay 4 is to be received by the seat pillar 5 is formed integrally with a band clamp 21 fixed to the seat pillar 5 in advance. Alternatively, it is also possible to apply a flat part 23 formed at the end of the carrier stay 4 and to fix the two with screws 24.

Further, the carrier 1 as a whole may be formed of a rod-shaped member or may be formed into various shapes by combining sheet metal, welding, etc.

Further, the carrier of the present invention is not limited to mountain bikes, but can be attached to any bicycle that has a general saddle, such as randonneurs and rod racers.

As explained above, the bicycle carrier of the present invention has the excellent effect that it can be easily attached to and removed from an existing saddle as needed, and can also function as an auxiliary saddle when attached. Demonstrate.
