Description

Detailed Description of the Invention

This invention provides a large amount of transport of luggage by large basket, try to ping cart at the time of using the walking assistance and, from the cash register passing after Shiyopingu, to your home, luggage Tsumemekawa, loading of the own-wheel vehicle loading platform, strapping, etc. Work and time can be reduced.

A conventional basket of a bicycle has a small capacity . It is installed on the front wheel handle side. Transport of heavy loads due to the basket, sense of instability is inevitable due to have a high of luggage inertia and center of gravity.

Problems to be solved by the invention

A basket mounted on a conventional bicycle has a smaller capacity than the large basket according to the present invention. A shopping loaded in the basket may not be operated unless a measure such as bunting is performed. The large basket of the present invention is expected to have a capacity about three times larger than that, and can carry a plurality of bags, long sleeves such as an attache baseball bat without difficulty,
With the method of using a shopping cart, it is not necessary to refill the basket belonging to the supermarket after passing through the cash register.
By owning the shopping cart (FIG. 5) of the present invention and the two shopping baskets (14) attached thereto, it is possible to return home by bicycle after passing through the cash register, thereby reducing labor and time. I can do it.

(A) The self-wheeling vehicle of the present invention secures a target space above the rear wheel by setting a long distance between the crankshaft (14) and the rear wheel shaft (15). The ping cart has an opening (11) in front of the wheel mounting frame, and the lower stage has a structure that can be slid up and down to prevent interference with the rear wheel when the apparatus is installed on the own vehicle.
To carts in the lower (10), a descent in Shiyopingu position (16), when the bicycle device lifts pulling the grip (17), previously suspended into the upper end hook (18), the upper end hook torsion spring ( 19) the you are prevented from dropping taken out (c) to ping basket (20 to carts lower part of FIG. 5), the procedure advance upholds lifting grip (17), then Fukkunigiri (21) below The lower part of the shopping cart (10) can be lowered gently (16).
(D) As shown in FIG. 18, the bicycle is loaded on the side of the side (22) with both left and right hands and tilted rearward so that the front wheel of the shopping cart is 1/8 arc-shaped on the entrance side of the wheel step (7). (8) Put on the part. Next, grab the cart walking bar (23) and push it forward, and check the connection between the front fixed handle part (1) and the rear fixed handle part (2), and support the cart running bar (23). While tightening, tighten the rear fixing lever (6). Next, tighten the left and right fixing lever (5) from the front of the cart.

Is located.
(E) Large baskets must be used interchangeably with shopping carts, and cannot be used at the same time. (F) Front fastening shaft (12) and rear fastening shaft (13) for securing to a bicycle are large. The basket and the shopping cart should be installed in the same position to be compatible.
(G) The front side fixed handle part (1) and the rear side fixed handle part (2) are for coupling the front fastening shaft (12) and the rear fastening shaft (13), respectively.
Both the left and right fixing levers (5) and the rear fixing lever (6) have a metal fitting (25) coupled to a portion located under the neck and penetrate the housing (31). Install with nut (24).
(H) The tip of the fitting (25) has a shape corresponding to the R shape of the tightening shaft, and the R portion (27) of the tightening base (26) functions as a sliding guide during mounting. ing.
(I) The wheel step (7) is fixed by a bracket A (28) in which the vicinity of the rear wheel shaft is on the input side and the wheel passage groove bottom is 1/8 arc shape (8). The mounting position on the wheel step, that is, the front side of the bicycle is set to a 1/3 arc shape (9), and this portion is fastened to the oblique tube (30) of the bicycle using the bracket B (29).

Embodiment of the Invention

The maximum width of the shopping cart and large basket used by the present invention is about 80% and 70% compared to the handle width. Both sides have an R shape.

The invention's effect

(B) Compared to baskets, which are called the front of a conventional bicycle, the large basket of the present invention has a capacity of about 300%, and is a long one that can be loaded and transported without any difficulty in ordinary packed shopping. A large box-like object can be advantageously used as such.
(B) When using the shopping cart, it is possible to return home immediately after passing the cash register, that is, it contributes to labor and time reduction and walking assistance.
(C) Loading on the rear wheel side is more stable when operating the handle than the front basket.
(D ) The present invention has a low center of gravity and excellent safety during operation.
