Description

[Detailed Description of the Invention] The present invention relates to a basket fixing mechanism for motorcycles and motorized bicycles.

Conventionally, when attaching a basket to the carrier of a motorcycle, it has been common to directly tighten the basket to the front or rear carrier of the motorcycle using threaded parts such as bolts and machine screws.

However, with this method of tightening using only screw parts, it is difficult to control the displacement of the basket due to vibrations and impacts of the vehicle body. Further, there is also the problem that the coating of the basket, which is made of plating or synthetic resin processing, is peeled off by the threads of the screw parts. Therefore, this idea is
To provide a basket fixing mechanism capable of fixing a basket without shifting against severe vehicle body vibrations and shocks.

The basket fixing mechanism according to the present invention includes an outer frame,
A basket fixing mechanism for fixing a basket provided with a mounting member at the bottom to a cargo receiving platform for motorcycles and motorized bicycles, which includes first and second longitudinal support members fixed to the outer frame and intersecting with each other. The mounting member is fastened to the first and second longitudinal support members by means of fastening means through at least a pair of plate-like members having recesses corresponding to the longitudinal support members located above the first and second longitudinal support members. It is characterized in that it is fixed to a lower longitudinal support member of the second longitudinal support members.

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

As is clear from FIG. 1, a cargo receiving stand 2 is provided behind a seat 1 of a motorcycle or a motorized bicycle. The loading platform 2 has a substantially rectangular steel pipe outer frame 3 fixed to the vehicle body (not shown), and is arranged approximately perpendicular to the traveling direction and separated by a predetermined distance, and has both ends facing outward. A pair of groove-shaped steel first longitudinal support members 6 and 7 are welded to the left end 4 (with respect to the running direction) and right end 5 of the frame 3, and the first longitudinal support members 6 and 7 are formed by bending. 7 and a fork-shaped second longitudinal support member 8 made of round steel, which is provided to intersect with the second longitudinal support member 7 at a substantially right angle.

The branch part 9 of the second longitudinal support member 8 is welded to the rear part 10 of the outer frame 3, and the shaft parts 11 and 12 extending parallel to the running direction from the branch part 9 are connected to the first longitudinal support member 6 on the front side. It is bent diagonally forward to the left and right in front of the . The shaft portions 11 and 12 bent diagonally forward to the left and right have their tip portions bent downward, and the bent portions 13 and 14 are welded to the left side 4 and right side 5 of the outer frame 3, respectively.

The basket 15 is formed by welding steel wires subjected to a predetermined bending process to each other, and includes a pair of plate-like members 16 arranged parallel to the first longitudinal support members 6 and 7. and 17 on the loading platform 2. Also, basket 1
5 is coated with oxidation prevention means such as plating or synthetic resin coating, which also has an aesthetic effect.

A pair of mounting plates 19 and 20 are attached to the horizontal steel wire 18 extending at right angles to the running direction at the bottom of the basket 15.
are welded in correspondence with each other. Mounting plate 1
At both ends of each of 9 and 20, among a plurality of vertical steel wires 21 extending below the horizontal steel wire 18 at right angles to the horizontal steel wire, that is, in the running direction, a vertical steel wire 21 near the both ends is provided.
A pair of through holes 22 and 23 are provided corresponding to the center of the pitch.

On the other hand, a pair of through holes 26 and 27 are provided in each of the webs 24 and 25 of the first longitudinal support members 6 and 7 in correspondence with the through holes 22 and 23, and a pair of nuts 28 and 27 are provided in the lower surface of each of the webs, respectively. 29 is welded. Further, a pair of elongated holes 30 and 31 are provided in the plate members 16 and 17 corresponding to the through holes 22 and 23, respectively.
is provided.

The basket 15 is fitted into the through holes 22 and 23 and the elongated holes 30 and 31, respectively, and is fitted with a nut 28.
It is fixed to the cargo receiving stand 2 by tightening a pair of screws 32 and 33, which are screwed into each of the screws 32 and 29.

Here, a pair of recesses 34 and 35 are provided on the lower surfaces of the plate-like members 16 and 17, into which the shaft portions 11 and 12 of the second longitudinal support member 8 are fitted.
Further, a plate member 16 is provided corresponding to the recesses 34 and 35.
A pair of protrusions 36 and 37 protrude from the upper surface of each of the vertical steel wires 17 and 17. The tapered portions 38 and 39 of the protrusions 36 and 37 are sandwiched between the vertical steel wires 21 so as to come into contact with the vertical steel wires 21, and their upper ends are connected to the horizontal steel wires 18. is in contact with.

As described above, by providing the plate-like members 16 and 17 between the loading platform 2 and the basket 15, the shaft portions 11 and 12 of the second longitudinal support member 8 of the loading platform 2 and the sides of the basket 15 are The steel wire 18 and the vertical steel wire 21 are in line contact through the plate members 16 and 17 (if the plate members 16 and 17 are not provided,
This results in point contact between the shaft portions 11 and 12 and the horizontal steel wire 18).

When an object with relatively high rigidity such as the shaft parts 11 and 12 comes into contact with an object with high flexibility such as the horizontal steel wire 18 and the vertical steel wire 21, the larger the contact range, the more the mutual contact due to external force increases. This makes it difficult for deviations to occur. Further, since the shaft portions 11 and 12 are partially fitted into the recesses 34 and 35 of the plate-like members 16 and 17, the above-mentioned displacement between them becomes even more difficult to occur.

Therefore, the tightening force exerted by the screws 30 and 31 acts effectively, and the basket 15 is firmly fixed to the cargo tray 2.

Further, in this embodiment, a case is shown in which the protrusions 36 and 37 are provided on the upper surfaces of the plate-like members 16 and 17, but as in a modification of this embodiment shown in FIG. The shaft portions 11 and 12 of the loading platform 2 are fitted into the pair of recesses 40 and 41, and each pair of elongated holes 42 and 43 provided at both ends.
The upper surfaces 46 and 47 of the pair of plate members 44 and 45 into which the tightening screws 30 and 31 are respectively inserted are made flat, and the upper surfaces 46 and 47 are in full contact with the vertical steel wire 21 of the basket 2. It is also possible.

In this modification, the same reference numerals as in the first embodiment are used for members having the same configuration as in the first embodiment, and the other parts are also constructed in exactly the same manner as in the first embodiment.

As detailed above, in the basket fixing mechanism according to the present invention, the cargo rack for motorcycles and motorized bicycles is composed of an outer frame and first and second longitudinal support members fixed to the outer frame and intersecting with each other. at least one pair of basket fixing mechanisms for fixing a basket having a mounting member on the bottom thereof to the basket, the basket fixing mechanism having a recess corresponding to an upper longitudinal support member of the first and second longitudinal support members; The mounting member is fixed to the lower longitudinal support member of the first and second longitudinal support members by fastening means via the plate member.

That is, by interposing the plate-like member between the cargo receiving platform and the basket, the basket is firmly fixed to the receiving platform.

Therefore, in the basket fixing mechanism according to the present invention, the basket will not shift even if external forces such as severe vibrations or shocks of the vehicle body are applied.

Furthermore, in the basket fixing mechanism according to the present invention, since the longitudinal support member is half-fitted into the recess provided in the plate-shaped member, it is necessary to insert the plate-shaped member between the cargo receiving platform and the basket. It requires less space.

Furthermore, in the basket fixing mechanism of this invention, the prevention of misalignment between the basket and the load-receiving platform is entirely the responsibility of the plate-like member, and the fastening screw is not directly involved in this. Therefore, since the threads of the screw do not come into contact with the basket, there is no need to worry about the plating or synthetic resin coating of the basket being stripped off by the external threads.
