Description

[Detailed description of the invention] This invention relates to a tank support device for motorcycles, etc., and is particularly suitable for use in oil tanks, fuel tanks, water tanks, etc. of motorcycles whose seats cannot be opened and closed. Regarding equipment.

In the above-mentioned motorcycles, etc., when a tank is installed below the seat, an injection port is provided above the tank when injecting oil, fuel, water, etc. into the tank.
Since it is close to the bottom of the sheet, there is a problem that the sheet gets in the way and makes it difficult to inject.

Conventionally, many proposals have been made to simplify the filling operation into such a tank.

For example, by attaching a removable cylinder to the injection port of a tank, and pulling out and fixing the cylinder from the injection port prior to injection, the injection port can be placed at a position protruding from the side of the seat. It is known that the length is extended.

However, such a structure has problems such as a large number of parts, a complicated structure, and complicated operations prior to injection work.

On the other hand, in order to simplify the operation prior to the injection work, the tank itself is movably supported by multiple guide shafts. There are also known devices in which the device can be pulled out from the storage position.

However, in such a tank mounting structure, the structure is complicated, and due to the dimensional error between the guide shaft and the engaging part of the tank that engages with this guide shaft, it is difficult to install the tank at the storage position. Since rotation and wobbling of the tank occur, there is a problem in that high dimensional accuracy is required for the engagement between the guide shaft and the engaging portion of the tank.

This invention was made against the above-mentioned background, and its purpose is to be able to support the tank movably between the storage position and the pull-out position with an extremely simple structure, and to support the tank in the storage position. An object of the present invention is to provide a support device for a tank of a motorcycle, etc., which does not cause rotation or rattling of the tank.

The feature is that it is fixed to the frame that supports the seat and extends almost vertically downward from the part that is fixed to the frame, and from this locking part horizontally towards the side of the seat. A support member having an extended tank guide portion is provided, and the locking portion is configured to abut against a wall surface of the tank at a position away from a position where the guide portion and the tank are engaged at a storage position of the tank. By doing,
Even if there is some dimensional error in the engagement between the guide part and the tank, the tank is prevented from rotating around the guide part or wobbling at its storage position.

An embodiment of this invention will be described below with reference to FIGS. 1 to 4.

In the drawings, reference numeral 1 indicates a seat, 2, 3, and 4 frames forming part of the vehicle body frame, and 5 a fuel tank. a support member 6 welded to the frame 2;
The locking portions 7, 7' extend substantially vertically downward from the portion fixed to the frame 2, and the locking portions 7, 7' extend substantially horizontally toward the side portion 1a of the seat 1. It has a guide part 8.

This guide member 8 is comprised of side surfaces 7a, 7'a extending from the locking portions 7, 7', an upper surface 9, and a lower surface 10.

The support member 6 supports the oil tank 11 so as to be movable between a storage position shown in FIG. 2 and a pulled-out position shown in FIG. This tank 11 has wall surfaces 12, 12' which come into contact with the locking portions 7, 7' in the storage position of the tank shown in FIG. 2, and side surfaces 12a, 12' extending from the wall surfaces 12, 12'. a
, an upper surface 13, and a lower surface 14.

A tank 11 that slidably fits into the guide portion 8
The hollow hole portion is constituted by the side surfaces 12a, 12'a, an upper surface 13, and a lower surface 14.

Further, an inlet 15 for injecting oil is provided at the top of the tank 11, and normally this inlet 1
5 is closed by a cap 16.

A washer 17 is installed at the right end of the hollow hole.
is welded to the tank 11. This washer 17 is provided with a tightening member 22.

This tightening member 22 has a male threaded portion 1 which is screwed into a female threaded portion 18 fixedly provided at the right end inside the guide portion 8.
9 and a knob portion 20. When storing the tank, this tightening member 22 screws the male threaded part 19 into the female threaded part 18, and the protrusions 21 and 21' formed at the lower left end of the locking part 7 are attached to the tank 11. The tank 11 is tightened to the support member 6 by tightening it until it contacts the left end surface 11a.

Furthermore, a locking portion 23 is provided at the tip of the tightening member 22.
is formed. This locking portion 23 is attached to the stepped portion 2 when the tank is pulled out at the position shown in FIG.
3a engages with the left end portion 18a of the female threaded portion 18, thereby locking the tank 11 to the support member 6, and in the storage position of the tank shown in FIG.
It is inserted into a hole 24a of a holding member 24 fixedly provided inside the guide section 8.

Here, the knob portion 20, the male threaded portion 19, the female threaded portion 18, and the projections 21, 21' constitute a tightening means for tightening the tank 11 to the support member 6 at the storage position.

Further, the stepped portion 23a of the locking portion 23 and the left end portion 18a of the female screw portion are connected to the tank 11 in the pulled-out position.
This constitutes a locking means for locking the support member 6 to the support member 6.

Hereinafter, the operation of the above-described embodiment will be explained. Before injecting oil into the oil tank 11, the knob 20 is rotated in the storage position of the tank shown in FIG. 2 to release the threaded engagement between the male threaded portion 19 and the female threaded portion 18. Then, pull out the tank 11 from the storage position shown in FIG.
3 to the pull-out position shown in FIG. 3, where it protrudes from the side 1a. During the movement, the hollow holes 12a, 12'a, 13, 14 of the tank 11 are
a, 7'a, 9, and 10.

Then, the stepped portion 23a of the tip portion 23 engages with the left end portion 18a of the female threaded portion 18, whereby the tank 11 is locked to the support member 6 at the drawn-out position shown in FIG.

In this state, the cap 16 is removed and oil is injected into the tank 11 from the can 25. After filling the oil, move the tank 11 to the left at the position shown in FIG.
1 and 21' are tightened until they come into contact with the left end surface 11a of the tank 11. Thereby, the tank 11 is secured in its storage position. In this state, the locking portion 23 is connected to the hole 24 of the holding member 24.
It is simply inserted into a.

Further, at the storage position of the tank 11, a guide portion 8 formed by the surfaces 7a, 7'a, 9, and 10 and a hollow hole portion formed by the surfaces 12a, 12'a, 13, and 14 are provided. As is clear from FIG. 4, even if there is a slight dimensional error in engagement with the guide portion 8, the locking portions 7, 7' of the support member 6 are in contact with the guide portion 8 in the retracted position shown in FIG. The wall surface 1 of the tank 11 is located at a position away from the engagement position with the hole.
2 and 12', the tank 11 will not rotate around the guide portion 8 in the direction of the arrow in FIG. 4 or shake.
Moreover, the means for holding the tank 11 in the retracted position and the means for holding it in the drawn-out position are concentrated in one location, thereby simplifying the structure.

As described above, according to the present invention, in a motorcycle or the like in which a tank is installed under the seat and the seat cannot be opened or closed, the work of filling fuel, oil, water, etc. into the tank can be done with an extremely simple configuration. It is possible to obtain a support device for a tank that can perform this very easily, and also to lock the support member at a position away from the engagement position between the hollow hole part of the tank and the guide part of the support member in the storage position of the tank. Since the part is configured to abut against the wall surface of the tank, even if there is a slight dimensional error in the engagement between the guide part and the hollow hole part, the tank will not rotate around the guide part or shake. There isn't.
