Description

[Detailed Description of the Invention] This invention relates to an attachment device that allows a bicycle luggage basket to be easily attached to and detached from a bicycle with a single touch.

Conventionally, bicycle luggage baskets have been fixed with screws and are integrally attached to the bicycle, making it inconvenient to use because they cannot be removed when shopping. In addition, the material of the luggage basket is limited, the selection range is narrow, and the design is also restricted.

This design is easy to operate without tools, and allows you to easily attach or not attach the luggage basket to your bicycle depending on the intended use, and it is convenient to use without the hassle of transferring shopping items to the basket. We aim to provide a product with a robust structure that can withstand long-term use without fear of damage, and with a tasteful design.

Hereinafter, this invention will be explained with reference to drawings that are examples. 1 is a bicycle luggage basket (hereinafter simply referred to as a luggage basket), and a hooking hook 2 is provided on the upper back side of the bicycle basket, and a lower hooking bracket is provided on the front part of the bottom surface. 3 is provided.

The engaging claw metal fittings 2 are provided with engaging claws 4, 4 corresponding to the upper and lower, left and right sides at required intervals on the upper and lower edges of the flat metal plate.
and 5, 5 are provided, and locking grooves 4a, 5a are provided on the inner edges of the engaging claws 4, 5 on the upper side near the mutually opposing tips.

The hooking fitting 3 has a U-shape with mounting portions 3a, 3a on both ends, and is attached to the cargo basket 1 with screws 15 and a back plate 16.

Reference numeral 6 denotes an arm fitting that is fixed to the bicycle frame and attaches the upper part of the luggage basket, and in the embodiment, the base end 6a
is attached to a Hawk stem (not shown), and the distal end 6b protrudes from both sides to form a T-shape, and the distal end is bent upward as shown and provided on the mounting surface.

Reference numeral 7 denotes a presser plate, which is fixed to the rear surface of the tip 6b of the arm fitting 6 with screws 8, 8, and both ends are formed wider than the tip 6b of the arm fitting 6, and both ends are pushed toward the front side as required. The width is bent and protrudes, and the spring receiver 7
a, 7a, and furthermore, spring housing grooves 7b, 7b are press-molded near the center of each.

Reference numeral 9 denotes a locking spring, which is curved into a U-shape and is used, one of which is used as a mounting portion 9a with its upper half accommodated in the housing groove 7b and the whole is mounted, and the other is a locking portion 9b which is attached to the holding plate 7. Its expansion is restricted by the spring receiver 7a, and it is arranged to be expandable and contractible in a space formed outside both ends of the tip 6b of the arm fitting 6 and inside the spring receiver 7a.

Reference numeral 10 is a basket receiving frame, which is made by curving a metal bar of the required length from the center, bending the whole into a U-shape on the plane, and then bending the second half of the required length upward in parallel at a required angle to stand up. A standing portion 10b is formed with an L-shaped side surface relative to the standing portion 10a, and then the supporting plate 11 is passed horizontally between the upper ends of the standing portion 10b, and the connecting portion with the standing portion 10b is welded and fixed. After overlapping the tip portion 6b of the arm fitting 6 and the presser plate 7 on the back side of the arm fitting 6, the screws 8 are used to securely fasten the end portion 6b of the arm fitting 6. moreover,
At the rear end of the bottom 10a of the cargo basket receiving frame 10, a lower support rod is provided with a support leg plate 13 whose tip end is fastened to the front end of a brake mounting bolt 12 on a bicycle frame, in the embodiment, a front fork. 14
The connecting parts are welded and fixed.

In addition, a knob ring 9c is provided at the top end of the locking portion 9b of the locking spring 9, and a stop ring 9c is provided at the top end of the mounting portion 9a.
d are provided integrally.

Since this invention is constructed as described above, in order to attach the luggage basket 1 to the bicycle, place the luggage basket 1 on the luggage basket receiving frame 10 and move it rearward. The lower hooking bracket 3 is hooked to the front end of the basket receiving frame 10, and in conjunction with this operation, the arm bracket 6 is inserted between the hooking claws 4, 4 and 5, 5 of the hooking hook bracket 2 on the upper back side of the cargo basket 1. tip 6b of
and the holding plate 7 are fitted, and then the locking portion 9b of the locking spring 9 is inserted into the locking grooves 4a, 5 of the engaging claws 4 and 5.
a to lock the fitting.

Next, to remove the luggage basket 1 attached to the bicycle,
When the locking portion 9b of the locking spring 9 is contracted by applying it to the inner side, for example, against the knob 9c at the top end, the locking portion 9b is released from the engaging pawls 4 and 5, and the lock is released. Then, by pulling the cargo basket 1 forward, it can be removed from the cargo basket receiving frame 10.

In addition, when the tips of the hooking claws 4 and 5 are formed in an arc shape, when the luggage basket 1 is attached to a bicycle, the hooking claws 4 and 5 have their inner edges horizontally touching the locking portion 9b of the locking spring 9. When it is pressed and bent to engage the support plate 11 and the locking grooves 4a and 5a match, the locking spring 9 automatically locks the locking claws 4 and 5 as described above.

Since this invention is as described above, it can be attached to or removed from the bicycle with a simple operation.
If necessary, it can be used in two ways: with or without a basket attached.

Furthermore, since the structure is simple, manufacturing costs can be reduced, and in addition, simply pressing and bending a spring is sufficient for attachment and detachment, making attachment extremely easy and ensuring reliable locking.

Also, in case of rain or other bad weather, remove the basket,
Since it can be stored separately, items that are sensitive to moisture, such as elegant items such as rattan baskets, can be used as equipment, and the design can be interesting.
