Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a luggage basket to a front cargo bed or a rear cargo bed of a bicycle or a motorcycle.

[0002]

2. Description of the Related Art Conventionally, a box-shaped luggage basket is generally fixed to a front luggage carrier or a rear luggage carrier of a bicycle or a motorcycle by screws or the like, but recently, loading and unloading of luggage is carried out. In consideration of inconvenience of work, etc., a technique for detachably attaching a luggage basket to a luggage carrier is disclosed.

As a technique for making this luggage basket detachable, for example, there is one disclosed in Japanese Utility Model Laid-Open No. 5-24492, and the technique described in this publication is fixed to the front part or the rear part of a bicycle. A base member and a luggage basket removably connected to and fixed to the base member are provided. By placing the luggage basket on the base member from above, the engagement holes on the luggage basket side are formed on the base member side. Is provided with a holding mechanism that engages the engaging piece against the spring.

[0004]

By the way, as the holding mechanism of the technique described in the above publication, a structure for elastically urging the engaging piece or the like by a spring is adopted, so that a separate member such as a coil spring is required. Therefore, there are problems such as an increase in the number of parts and an increase in the number of assembly steps on the production line. Further, since a spring receiving seat is required as a holding mechanism, there is a drawback that the structure becomes complicated and the production cost becomes high when the base member is made of a synthetic resin material.

Further, even if the base member is made of a synthetic resin material, the spring is generally made of a spring steel wire, and when used as a part for a motorcycle exposed to rainwater or the like. , Must be rustproofed, etc.
There is a drawback that the overall cost is high. In addition, anyone can easily remove the luggage basket, which may result in theft of the luggage basket.

In addition to the above publications, there is a technique for easily attaching and detaching a luggage basket to and from a luggage carrier (for example, Japanese Utility Model Publication 5).
8-73097 and Japanese Utility Model Laid-Open No. 3-73281), even in these techniques, a spring steel wire is used as a mechanism for holding a luggage car, and the same drawbacks as in the above publication exist. Further, no means for preventing theft is applied.

In view of the above, an object of the present invention is to provide a luggage car fixing structure for a two-wheeled vehicle which can securely hold a removable luggage car without using a spring steel wire. Still another object of the present invention is to provide a luggage basket fixing structure capable of preventing the luggage basket from being stolen.

[0008]

In order to achieve the above object, in the present invention, a cargo bed fixed to an appropriate position of a two-wheeled vehicle, for example, an upper front wheel or an upper rear wheel, and detachably fixed to this cargo bed. In the fixed structure of the luggage basket,
An engaging piece is projected on the bottom of the luggage basket, the upper surface of the luggage carrier is formed into a flat shape, and an engaging hole is formed in the luggage carrier so that the engaging piece can be fitted from above. A structure provided with a lock mechanism that does not use a spring steel wire to hold the luggage car immovably in the vertical direction and prevent the luggage car from moving in the front-rear direction by moving it in the front-rear direction after fitting from above. Has been adopted.

The plane of the upper surface of the loading platform is
This is to prevent the protrusion from interfering with the fixing of the luggage when the other luggage is directly placed on the luggage carrier when the luggage basket is removed. Further, the reason why the engaging piece is not provided on the cargo bed side is also for the same reason.

As the structure of the engaging piece, a hanging piece protruding from the bottom of the luggage basket and a lateral piece bent at the lower end of the hanging piece are formed into a substantially L shape. By fitting the to the engaging hole from above and then moving in the front-rear direction, the luggage basket can be held immovable at least in the vertical direction. Further, when the hanging piece comes into contact with the hole wall of the engaging hole, either the forward or backward direction is regulated, and the locking mechanism cooperates with the restricting action of the hanging piece to shift the backward or forward direction. By restricting the movement of the luggage basket in the front-rear direction, the luggage basket can be securely and firmly fixed.

In addition to the above structure, as a structure for preventing rattling of the luggage car in the left-right direction, an engaging piece on the side of the luggage car is provided with a hanging piece protruding from the bottom of the luggage car and a left-right direction from the lower end thereof. A lateral piece formed by bending is formed into a substantially L-shape, while an engagement hole on the side of the cargo bed is formed with a fitting portion having the same shape as the lateral piece.
It is also possible to employ a configuration in which a plan view is formed into a hook shape from the sliding portion which is continuous with this in the front-rear direction and has the same lateral thickness as the hanging piece.

According to this structure, since the hanging piece is located at the sliding portion, the lateral piece is restricted by the lower surface of the loading platform to prevent the hanging piece from coming out upward, and the hanging piece is restricted by the sliding portion. This will prevent rattling in the left-right direction.
Of course, the bottom of the luggage basket can be prevented from slipping down, but in order to prevent rattling in the vertical direction, it is desirable that the length of the hanging piece be set to be approximately the same as the thickness of the luggage carrier. The engagement relationship between the engagement pieces and the engagement holes may be one, but by providing a plurality of engagement pieces, the engagement and fixation relationship can be maintained more reliably and firmly.

In the engagement hole, the fitting portion and the sliding portion are arranged in the front-rear direction, that is, the structure in which the slip-out is prevented by sliding the luggage basket in the front-rear direction is
For the user, if the fitting part and the sliding part are arranged in the left-right direction, the loading position of the luggage basket with respect to the loading platform may be uncomfortable, but the sliding direction in the front-back direction is also considered in terms of gravity balance. Is considered to be easy.

However, when fitting the engaging piece into the engaging hole or sliding after fitting, it is a little uncertain whether the luggage car can be surely guided to slide in the front-rear direction. Therefore, it is desirable to form the ridges for guiding the luggage car in the front-rear direction on the left and right sides of the bottom surface of the luggage basket at intervals slightly larger than the left and right width of the luggage carrier.

Various structures are conceivable as the lock mechanism that does not use a spring, and the typical ones are as follows. As one of the locking mechanisms, a lock pin provided so as to abut a surface of the front surface and the rear surface of the luggage car on the side where the engagement piece is disengaged from the engagement hole, in the engagement holding state of the engagement piece, It is considered that the simplest structure is a structure provided with an insertion hole provided in the bed so that the lock pin can be inserted and removed freely. If this lock pin is provided so that it can be removed from the insertion hole, the lock pin will not get in the way when the luggage basket slides back and forth, and will be lost if the lock pin is connected to the bicycle by a chain or the like. The fear can be avoided.

There are various conceivable shapes of the lock pin, and a wire for locking wheels and a chain-type locking device can be generally used. In this case, when the method of passing the wire portion of the locking device through the insertion hole and locking the wheels of the bicycle at the same time when locking the bicycle is adopted, it is possible to lock the bicycle, lock the luggage basket, and prevent theft at once.

Further, as another lock mechanism, in the engagement holding state of the engaging piece, among the engaging hole peripheral portion of the lower surface of the loading platform and the engaging piece so as to prevent the engaging piece from moving in the horizontal direction. By adopting a configuration in which a convex portion is formed on one side and a concave portion is formed on the other side so as to engage with this convex portion, and the convex portion is slip-fitted into the concave portion, the luggage basket can be locked with a simple structure, Further, when the luggage basket and the luggage carrier are formed of a synthetic resin material, they can be integrally molded at the same time, which leads to a reduction in production cost.

Further, as another lock mechanism, it is provided so as to abut on a surface of the front side and the rear surface of the luggage basket on the side where the engaging piece is disengaged from the engaging hole, in a state where the engaging piece is held in engagement. If the lock lever is provided and the lock lever is supported in the recess formed on the upper surface of the auxiliary base so as to be rotatable around the horizontal axis between the standing posture and the retracted posture, the lock can be reliably performed. At the same time, the structure is such that it can be prevented from protruding from the upper surface of the auxiliary table even in the immersed state.

The lock mechanism typified by these, in the form of sliding the luggage basket in the front-rear direction to engage and hold the engagement pieces in the engagement holes, employ the above-mentioned ones singly or in combination. By adopting these in combination, the luggage basket can be more firmly fixed.

In the fixing structure as described above, the engagement piece is prevented from sliding by sliding in the front-back direction, but in addition to this, the above object can be achieved by rotating the engagement piece side in the horizontal direction. can do. That is, the engaging piece is composed of a hanging cylinder projecting from the bottom of the luggage basket and a lateral piece projecting laterally from the lower end thereof, and the engaging hole is fitted with the hanging cylinder and a hanging cylinder having the same shape as the lateral piece. Part and horizontal piece fitting part,
It is also possible to employ a configuration in which a side wall of the hanging tube fitting portion is provided with a notch for rotating and fitting the lateral piece continuously with the lateral piece fitting portion.

By rotating the lateral piece, it is possible to prevent the luggage basket from coming off in the vertical direction with a simple structure. Here, it is more optimal to form one hanging cylinder at the center of the bottom of the luggage basket in a balanced manner. This is for keeping the flat state as much as possible by making it protrude so as to be flush with the upper surface of the luggage carrier.

It is a usual technical means that the carrier is composed of a carrier fixed to the vehicle body frame of the motorcycle and an auxiliary base made of synthetic resin fixed to the upper surface carrier of the carrier. In this case, the luggage basket can be fixed simply by attaching the auxiliary stand to the carrier already installed on the bicycle. As a fixing structure for this auxiliary base, a metal plate that is long in the left-right direction is applied from above and below both sides of the carrier top surface of the carrier, and the metal plate is tightened by inserting a screw member from above the auxiliary base. It is generally fixed, but if this fixing structure is adopted, the work must be performed while temporarily holding two vertically long metal plates in the left-right direction, and the work becomes complicated.

In view of this, in the present invention, a fixing member is provided for holding the wire rod forming the upper surface load receiving base of the carrier from below and fixing the auxiliary base to the upper surface load receiving base by a screw member inserted from above the auxiliary base. , As the fixing member, a fitting groove for fitting the lower half of the wire rod, an insertion hole for inserting the screw member, and a configuration including tightening means for tightening the screw member in the insertion hole, Tightening work is possible simply by holding the fixing member with one hand.

In particular, depending on the carrier, there are many cases in which the intervals and sizes of the wire rods constituting the load receiving tray are not constant. Therefore, it must be taken into consideration that the portion for tightening the auxiliary base varies depending on the fixing member. In order to deal with this, the present invention adopts a configuration in which a screw member insertion hole that is long in the left-right direction is formed in the auxiliary base. On the other hand, when tightening the screw member, the fixing member is put in the free hole after inserting the tip of the screw member into the screw hole of the fixing member, and the fixing member also rotates together with the rotation of the screw member. And cannot be tightened.

Therefore, in the present invention, a long screw member insertion hole is formed in the left-right direction of the auxiliary base, and the upper surface of the fixing member is engaged with the screw member insertion hole in order to prevent the fixing member from rotating around. A structure was adopted in which a rotation stop protrusion was formed to prevent rotation of the fixing member around the screw member when tightening the auxiliary base.

As the tightening means, various structures such as a structure in which a screw is cut in the hole wall of the insertion hole, a structure in which a nut is embedded in a part of the insertion hole, and a structure in which the screw member itself is a tapping screw can be adopted.

The above embodiment is an invention of a structure for attaching an auxiliary base to an existing carrier. In addition to this, the existing carrier is abolished as a cargo carrier, and the auxiliary carrier and the cargo carrier are made of a synthetic resin material. It is also possible to adopt a structure in which a connecting fork that can be connected to the supporting pipe of the saddle is also integrally formed, and only carrier legs such as a metal pipe are rotatably fixed to the connecting fork.

[0028]

In the above structure, when the luggage basket is mounted on the luggage carrier, the luggage basket is placed on the luggage carrier and the engaging piece at the bottom of the luggage basket is fitted into the engaging hole of the luggage carrier from above to move the luggage basket in the horizontal direction. Move to the required distance to. Then, the lateral piece of the engaging piece is located on the lower surface of the loading platform, and at least the vertical direction cannot be pulled out. Further, the hanging piece comes into contact with the hole wall of the engaging hole, which cooperates with the locking mechanism. By the action, the movement of the luggage car in the front-back direction is also restricted, and the same engagement holding state as when using a spring steel wire or the like can be obtained. Therefore, the number of parts is reduced as compared with the case where the spring steel wire is used, and the rustproofing process, the spring receiving seat and the like are not necessary, so that it is possible to provide a low-cost luggage basket fixing structure.

In particular, if the substantially L-shaped engagement piece and the hook-shaped engagement hole in plan view are engaged in a manner that cannot be slipped out by sliding the luggage basket in the front-rear direction, the luggage cage will move horizontally and vertically. It is possible to prevent rattling as much as possible, and the presence of a plurality of these engagement relationships enables reliable and firm fixation.

In this case, since the guide ridges are formed in the front-rear direction on the left and right end portions of the bottom of the luggage basket, the guide ridges can slide in the front-rear direction while being fitted to the left and right end portions of the luggage carrier. Therefore, sliding can be performed smoothly.
After this sliding is performed, by adopting various lock mechanisms, it is possible to securely and firmly fix the luggage basket without using the spring steel wire. Moreover, the left and right guide ridges on the bottom surface of the luggage basket smoothly guide the engagement pieces of the luggage basket to the engagement holes, and also contribute to the prevention of rattling in the horizontal direction when the luggage basket is fixed. . Note that the luggage basket can be easily removed by releasing the lock mechanism and pulling out the engaging piece from the engaging hole.

On the other hand, if the rotary engagement system is adopted as the fixing structure of the luggage basket, the lateral piece is fitted laterally by simply rotating the luggage basket after fitting the engaging piece of the luggage basket into the engagement hole. It gets into the joint and the luggage basket cannot be pulled out. In this case, like the lock mechanism described above, it is possible to hold it by the engagement of the convex portion and the concave portion, but since the luggage basket can hardly rotate during traveling of the bicycle etc. There is no need to provide parts and recesses. Also,
The luggage basket can be easily removed by rotating the luggage basket in the opposite direction to the above.

Further, when the carrier is composed of the carrier and the auxiliary base, it is usual to fix the auxiliary base to the existing carrier carrier with the screw member. In this case as well,
If a fixing member having a fitting groove that fits into the wire rod of the load receiving base is adopted, positioning of the fixing member can be easily performed. If it is inserted into the screw member insertion hole on the auxiliary table side, it is possible to prevent accompanying rotation even when tightening the screw, and it is possible to easily perform tightening work.

Further, regarding the loading platform, if the loading platform itself is an auxiliary platform made of synthetic resin, the metallic loading platform etc. can be omitted and a simple luggage basket fixing structure can be provided.
