ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an article housing device of a motorcycle disposed under a seat and adapted to house a long article such as a U-shaped lock device.
A U-shaped lock device commercially available as a lock device for preventing a motorcycle from being stolen is widespread because it is very strong as compared with a chain lock, a wire lock, or the like. However, because the U-shaped lock device can not be folded into a compact size unlike the chain lock, the wire lock, or the like, the U-shaped lock device is difficult to be housed in a housing device having a small capacity and provided under a seat of the motorcycle. A conventional example of a structure for housing the U-shaped lock device under the seat is disclosed in Japanese Patent Laid-Open Publication No. HEI 7-89472, for example.
Although the structure of the conventional example is suitable to a road sports type of motorcycle in which a position of the seat is relatively high and a front-to-rear (longitudinal) length of the seat is large, the structure is difficult to be applied to an American type of motorcycle, for example, in which the position of the seat is low and the front-to-rear length thereof is short because a thickness of a cushion of the seat can not be increased and a body layout is severely limited. Moreover, the above structure of the conventional example is for housing only a U-shaped lock device and can not house other types of long articles such as a collapsible umbrella.
SUMMARY OF THE INVENTION
An object of the present invention is to substantially eliminate defects or drawbacks encountered in the prior art mentioned above and to provide a housing device, for accommodating articles, of a motorcycle which can comfortably house a long-size article such as U-shaped lock device without being affected by a height and a length of a seat, a body layout, or the like and without affecting a swing arm supporting a rear wheel.
This and other objects can be achieved according to the present invention by providing a housing device, for accommodating articles, of a motorcycle which comprises a lateral pair of frame bodies, a pivot shaft connected between the frame bodies, a swing arm supported to be swingable to the pivot shaft and supporting a rear wheel and in which a housing box is disposed below a seat, the housing box being composed of an upper portion and a lower extension portion which extends vertically downward so as to pass through a space of the swing arm between the pivot shaft and the rear wheel in an installed state of the motorcycle.
In a preferred embodiment, the housing box has a size decreased downward as viewed from a side of the automobile in an installed state and has a decreased size portion of the housing box passes through the space of the swing arm.
The swing arm is provided with a lateral pair of arm members extending both lateral sides of a body of the motorcycle, a bridge member is disposed so as to connect the arm members and the pivot shaft connects both the arm members so as to define a space between the pivot shaft and the bridge member through which the lower extension portion of the housing box passes.
The lower extension portion of the housing box has a longitudinal length and a width length which is larger than the longitudinal length.
At least an uppermost portion and a lowermost portion of the housing box is provided with fixing portions for fixing the housing box to the body of the motorcycle body.
According to the the housing device of the motorcycle of the structure mentioned above, since the housing box disposed under the seat extends downward such that the housing box has a portion vertically passing through the swing arm supporting the rear wheel between the pivot shaft and the rear wheel, the vertical length of the housing box can be increased satisfactory and, accordingly, the long article such as U-shaped lock device can be housed comfortably without being affected by the height and the length of the seat, the body layout or the like.
Furthermore, the size of the housing box decreases downward when the housing box is viewed from the side, the longitudinal length of the portion of the housing box is smaller in size than the width of that portion, and only the smaller portion passes through the swing arm, so that the housing box can pass through the swing arm without affecting the swing arm and, accordingly, the long article can be housed.
Still furthermore, since the housing device is fixed to the motorcycle body at at least uppermost portion and the lowermost portion, the housing box vertically extending can be firmly mounted to the body.
The nature and further characteristic features of the present invention will be made clear in the following descriptions with reference to the accompanying drawings.
