JPH11189187A - Front basket burglar preventing tool for bicycle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a burglar preventing tool capable of preventing damage caused by the theft or jumping-out of a cargo or the like housed in a front basket, easy to be used and easily handled as a product. SOLUTION: A cap plate is attached to a fixed member fixed to the backside of the front basket B of a bicycle so as to be freely rotated in upper and lower directions, and by providing springs 11 and 11 to the attaching parts of the cap plate 2 and the fixed member, a spring force for lower direction energizing in the front basket B is supplied to the cap plate 2. When the cap plate 2 is raised against the spring forces of the springs 11 and 11, a cargo or the like is housed and a hand is released, the cap plate 2 is energized in a lower direction again by the springs 11 and 11, and thus the cargo or the like is pressed by the cap plate 2 and guarded. Also, since the cap plate 2 is separated from the front basket, an increase in size is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security device for preventing a bag or luggage, etc., stored in a front basket of a bicycle from being stolen by snatching or the like.

[0002]

2. Description of the Related Art To prevent this kind of theft, for example,
2. Description of the Related Art A front basket in which a lid plate is provided at an upper portion of an opening so as to be rotatable in a vertical direction is known. The cover plate is attached via a hinge formed of a ring or the like, and by covering the cover plate from above, it is possible to prevent the hand or the like stored in the front basket from being easily accessed.

[0003]

However, this front basket has a problem in that the lid plate is easily opened by the vibrations of the bicycle during running, and the luggage or the like may jump out to the outside and be damaged. In this case, a locking means such as a hook or a string can be provided on the cover plate, but it takes time and effort to open and close the cover plate, and there is a risk that it is difficult to take in and out luggage and the like.

On the other hand, since the front basket body is bulky, there is a problem that a space is required for transportation and storage, and it is difficult to handle.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a security device for a front basket which can prevent the luggage or the like from being stolen or damaged by jumping out, is easy to use, and is easy to handle as a product.

[0006]

According to the present invention, a cover plate is attached to a fixing member fixed to the rear side of a front basket of a bicycle so as to be rotatable in a vertical direction.
By providing a spring at the attachment portion between the cover plate and the fixing member, a security device for the front basket in which a spring force for urging the cover plate downward in the front cage is provided.

In this security device, when the fixing member is fixed to the rear side of the front basket, the cover plate is raised upward against the spring force of the spring, and when the luggage or the like is stored and released, the cover plate is re-opened. It is urged downward by a spring.

As a result, the luggage and the like are guarded by being pressed from above by the lid plate, so that they cannot be easily taken out by inserting a hand, and do not unexpectedly jump out due to vibration during traveling. Further, since it is separated from the front basket main body, it is not bulky and suitable for transportation and storage.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The security device shown in FIGS. 1 and 2 has a fixing plate 1 (fixing member) fixed to the back side of a front basket B of a bicycle, and a cover plate 2 rotatable vertically. It is configured to be attached.

[0010] The fixing plate 1 is formed with a pair of left and right side-to-side elongated screw holes 3, 3 extending vertically, which are formed in parallel with each other. It is screwed together with the front basket B while being sandwiched between them. On both sides of the fixed plate 1, there are provided a pair of support shafts 4, 4 projecting from both ends from the lower end of the fixed plate 1 and extending above the front basket B. The upper ends of the support shafts 4 and 4 are bent obliquely forward, and ring portions 5 and 5 are formed at the ends of the shafts 4 and 4 so as to be folded back. Between the support shafts 4, 4 and the fixed plate 1, reinforcing vertical rails 6, 6 and a horizontal rail 7 are passed.

The cover plate 2 has a structure in which the same mesh as that of the front basket B is applied to a frame 8 slightly smaller than the upper opening of the front basket B, and is reinforced by a plurality of vertical bars 9, 9 provided. I have. On both sides of the cover plate 2, a pair of connection shafts 10 and 10 protruding rearward and having bent shapes in directions approaching each other and fitted into the ring are provided. Springs 11 are mounted between the connection shafts 10 and the support shafts 4, thereby urging the cover plate 2 downward in the front basket B. A spring force is applied.

In this front basket security device, the fixing plate 1 is fixed to the rear side of the front basket B, and the cover plate 2 is raised upward against the spring force of the springs 5, 5 to store the luggage L. When the hand is released, the lid plate 2 is again urged downward by the springs 5,5.

As a result, the luggage L is guarded by being pressed from above by the lid plate 2, so that the luggage L cannot be easily taken out as long as the hand is inserted, and does not suddenly jump out due to vibration during traveling. . Also, since it is separated from the front basket B main body, it is not bulky and is suitable for transportation and storage.

When not in use, the cover plate 2
Is pressed against the back side of the front basket B, so that the appearance is neat and the design is excellent.

Further, since the mounting holes 3, 3 for screwing are elongated in the vertical direction, the mounting position can be adjusted up and down, so that the front basket B having various heights can be accommodated.

Although the illustrated fixing plate 1 is located on the outer surface side of the front basket B, it may be fixed on the inner surface side. Further, a key may be provided on the cover plate 2 so that the cover L can be locked at the upper edge of the front basket B to prevent theft of the baggage L while the bicycle is parked.

[0017]

As described above, in the bicycle front basket security device according to the present invention, the lid plate is urged downward in the front basket by the spring force of the spring. Not only does it have a high security effect because it is held down by a lid plate and is guarded, it also does not suddenly jump out of the front basket with vibration during traveling.

Also, since it is separated from the front basket main body, it is not bulky and is suitable for transportation and storage. When not in use, the lid plate is pressed against the back side of the front basket. Therefore, the appearance is clear and the design is excellent.

Further, by forming a vertically elongated mounting hole in the fixing member, the mounting position with respect to the front basket can be adjusted up and down, so that it is possible to cope with front baskets of various heights. Easy to use.
