Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of a shopping car that can be connected to a bicycle.

Prior Art This type of shopping car has a back frame made by bending a tubular member into a substantially rectangular shape, and the upper sides of the left and right sides of the back frame are bent so as to project horizontally, so that the back frame is generally horizontal. A handle is formed, and connecting rods that slide in the axial direction of both sides of the handle are provided on both sides of the handle, and a substantially semicircular locking portion is formed at the tip of the connecting rod, and the locking portion is formed at the tip of the connecting rod. A device is known in which a claw is provided in the stop portion so that it can freely move in and out (Utility Model Application No. 51-92852).

Problems to be Solved by the Invention This shopping car is connected to a bicycle by hooking the roughly semicircular locking part to the bicycle's cargo bed.
Simply hooking this approximately semicircular locking portion onto the bicycle carrier is not sufficient to connect the bicycle to the bicycle, and prevents the locking portion from falling off the bicycle carrier while the bicycle is running. In order to prevent this, it is necessary to hook the locking part to the bicycle carrier and then pull out the claw from the locking part with your finger to close the opening of the locking part. The connection work becomes extremely complicated. Further, in this shopping car, after the claw is pulled out from the locking portion to close the opening of the locking portion, a means is provided for causing the pulled-out nail to maintain a state in which the opening of the locking portion is closed. Since there is no such provision, there is a risk that the pawl may be pulled into the locking part due to vibration while the bicycle is running, opening the opening of the locking part, and as a result, the locking part may fall off from the bicycle carrier.

SUMMARY OF THE INVENTION An object of the present invention is to provide a shopping car that can be reliably connected to a bicycle with a single touch.

In the shopping car according to the present invention, the jointer attached to the tip of the towing handle has a main body having a substantially C-shaped vertical section, and a jointer that rotates along the side of the main body at one end of the main body. a rocking plate whose one end is freely pivoted to close or open an opening of the main body having a substantially C-shaped longitudinal section; A stopper provided at the other end is stretched between the swing plate and the main body, and the swing is moved in a direction in which the free end of the swing plate abuts and locks on the inner side of the stopper. It is configured to include a tension spring that constantly biases the moving plate to rotate.

Function In the shopping car according to the present invention, when the swinging plate is applied to the frame of the cargo bed and the jogner body is pressed when connected to a bicycle, the pushing force causes the swinging plate to resist the biasing force of the tension spring. The biasing force causes it to rotate in the opposite direction to the direction in which it is being urged to rotate, and as it rotates, the opening of the joiner body opens and the frame of the cargo platform closes to the free end of the rocking plate. At the same time, the rocking plate rotates by the biasing force of the tension spring and comes into contact with the stopper, so that the joiner body is connected to the loading platform. As described above, the shopping car according to the present invention can be connected to a bicycle carrier with one touch by simply pressing the joiner main body against the frame of the carrier. In addition, once the connection is made, the rocking plate is pressed against the stopper by the biasing force of the tension spring to keep the opening of the joiner body closed, so that when the bicycle is running, There is no risk of it falling off the carrier.

Embodiments Hereinafter, embodiments of a shopping car according to the present invention will be described with reference to the accompanying drawings.

The shopping car according to the present invention can be connected to a bicycle loading platform, and as shown in the first figure, this shopping car 1 includes a metal towing handle 10, a metal frame 11 foldably connected to the handle, and a metal frame 11 that is foldably connected to the handle. 1 cloth or plastic bag attached to a frame
22, three legs 13 provided below the metal frame 11, and wheels 15 each attached to the lower end of each leg 13 via a shock absorber 14, forming a tricycle. When this shopping car 1 is towed by a bicycle, the legs that support the front wheels can be folded, so that when the car is being towed, it can be moved using only the rear wheels. In addition, the handle for towing 10
A jointer 16 is provided at the tip of the
By connecting this joiner 16 to the loading platform 30 of the bicycle 3, the shopping car 1 can be connected to the bicycle 3.

This jointer 16 is attached to the towing handle 1 of the shopping car 1, as shown in FIGS. 2a and 2b.
The joiner main body 17 having a substantially C-shaped longitudinal section is attached to the joiner main body 17, and the main body 1 is attached to the side of the joiner main body 17 so as to close the opening 17a of the joiner main body 17.
A rocking plate 1 rotatably supported along the side of 7.
It consists of 9. More specifically, a horizontal plate 17c extending laterally is integrally formed on the lower edge of the joiner body 17 as shown in FIG. The lower end 19a of the rocking plate 19 is rotatably supported by a pin 20 on the side of the lower end 17b of the joiner main body 17. Further, a tension spring 21 is stretched between the rocking plate 19 and the horizontal plate 17c of the joiner main body 17, and the rocking plate 19 is rotated clockwise in FIG. 2a by the tension spring 21. However, the upper end of the rocking plate 19 comes into contact with a stopper 17d that is integrally formed on the upper end of the joiner body 17 and protrudes to the same side as the rocking plate 19. Possibly the opening 17 of the joiner body 17
A is always occluded.

In the shopping car configured in this way, when the jogner main body 17 is pressed while the rocking plate 19 is applied to the frame 31 of the loading platform 30 of the bicycle,
The pressing force causes the rocking plate 19 to rotate counterclockwise about the pin 20 while resisting the action of the tension spring 21. With this rotation, the opening 17a of the joiner main body 17 is opened and the loading platform 30 is opened.
At the same time that the frame portion 31 of the rocking plate 19 is fitted into the opening 17a over the free end of the rocking plate 19, the rocking plate 19 is rotated clockwise by the tensile force of the tension spring 21 and is pressed against the stopper 17d of the joiner body 17. Since they come into contact and close the opening 17a, they can be reliably connected to the bicycle with a single touch.
Also, the jointer main body 17 is connected to the frame 31 of the loading platform 30.
In the state in which the rocking plate 19 is pressed against the stopper 17d by the tension of the spring 21, the opening 17a of the joiner body 17
Since the space is closed, the Joyner body will not come off the loading platform while the bicycle is running.

Further, the jogner main body 17 can be configured to be attached to the towing handle 10 of the shopping car 1 via an elastic body 22 such as a spring spring (see FIG. 2a), and by such a configuration, the bicycle can be The elastic body 22 can eliminate the shock that occurs when the vehicle stops or suddenly stops. Furthermore, by attaching a rubber piece 23 to the inner surface of the joiner body 17 and also attaching a rubber piece 23 to the inner surface of the rocking plate 19, the jointer body 17 and the cargo bed are easily connected when the bicycle is running. Noise caused by collision with the frame portion 31 can be muffled.

Effects of the Invention As described above, according to the present invention, a shopping car that can not only be connected to a bicycle with a single touch, but also be securely connected to the bicycle loading platform without detaching from the bicycle loading platform while the bicycle is running. can be obtained.
