Description

The present invention relates to a two-wheel travel type handy carry cart for towing and transporting a load by connecting a two wheel travel type handy carry cart to a bicycle.

Conventionally, in order to transport a baggage by bicycle, the baggage is placed on a loading platform or a basket is attached to a position in front of the handle, and the baggage is put in the cart for transport.

To carry a load with a two-wheeled handy carry cart, place the load on the two-wheeled handy carry cart, and push or pull the two-wheeled handy carry cart manually by human walking. It was.

When a load was placed directly on the bicycle carrier or basket, the load on the bicycle was added and the running balance was hindered.

When carrying a two-wheel-drive handy carry cart with a person walking on it, the distance of the action range was limited.

Even when trying to connect a two-wheeled handy carry cart to a bicycle, the range of connection compatibility between the two-wheeled handy carry cart and the bicycle is limited depending on the size of the bicycle.

Even if the weight and shape of the load placed on the two-wheeled handy carry cart are different, if the angle cannot be adjusted, the angle position of the two-wheeled handy carry cart is constant, and the two wheels according to the weight and shape of the load It was not possible to stabilize the running balance by adjusting the angle of the running handy carry cart.

When a bicycle was parked with a two-wheeled handy carry cart connected, the two-wheeled handy carry cart occupied the parking area, which was in the way.

In order to solve the above problems, a two-wheel traveling handy carry cart with an angle adjusting connecting device according to the present invention, in which a two-wheel traveling handy carry cart with an angle adjusting connecting device is connected, is a bicycle and a two-wheel traveling handy carry cart. The connection is freely removable.

In order to make it possible to adjust the connection angle of the bicycle two-wheeled handy carry cart, a position shaft is provided at the center of the slightly upper part of the two-wheeled handy carry cart.

A shaft axis is provided at a central position of the shaft.

On both sides of the shaft, a member is provided with a semicircular base provided with several holes oriented in different directions.

On the opposite side, the same semicircular base is provided with a member on which several fixing nuts are mounted that are plane-symmetrical with holes facing in different directions.

A connecting shaft that enables one rotational movement is provided between the left and right semicircular base members, and the connecting shaft overlaps the positions of several semi-circular holes at different angles. A hole through which a screw bolt passes is provided at a position.

Screw bolts at the three holes of the semicircular member, the hole of the connecting shaft, the fixing nut provided in the semicircular member on the facing side, The structure is fixed by inserting and tightening.

A ring-shaped hook is provided at the tip of the connecting shaft, and a rotation shaft is provided at a position behind the ring-shaped hook at the tip of the connecting shaft.

In order to suppress the upward and downward swinging up at a certain height, by providing a projecting part on the member equipped with the rotating shaft, the member and the connecting shaft are intentionally held together, and the upward and downward swinging up is kept at a constant height. The structure is to be suppressed.

The pivot that holds the connecting shaft of the two-wheel-drive handy carry cart is detachable at the rear of the bicycle. The pivot is cylindrical, and the pivot of the fastener is a screw-type umbrella with an umbrella-shaped screw so that the connecting shaft does not come off. A lid is provided.

By carrying the cargo on a carry cart, the load on the bicycle can be reduced and the running balance is improved.

By carrying a bicycle with a load on a carry cart, it was decided to extend the distance from the walking range to the cycling range.

If the angle adjustment is possible, when connecting a two-wheeled handy carry cart to a large size bicycle, the angle of the connecting shaft can be set to a wide angle and the connection can be made in the direction in which the shaft is laid down. When connecting a wheeled handy carry cart, the connection range of the two wheeled handy carry cart and the bicycle was widened by making the angle of the connecting shaft an acute angle and enabling the connection in the direction where the shaft was raised, By widening the coupling compatibility range of the two-wheel-drive handy carry cart and the bicycle, it has become easier to handle various types of bicycles.

If the angle can be adjusted, and the load placed on the two-wheel-drive handy carry cart is heavy, connecting the shaft in the direction in which the shaft is laid down with the angle of the connecting shaft widened, the baggage can be transported in a low center of gravity. It becomes possible, and stable running can be achieved in a balanced state.

If the angle can be adjusted, even if the two-wheeled handy carry cart is parked with the bicycle connected to the bicycle, the angle of the connecting shaft is fixed in the vertical direction and the two-wheeled handy carry cart is set up to stand up to 2 The parking area of the wheeled handy carry cart can be reduced.

If angle adjustment is possible, when using it exclusively for a two-wheeled handy carry cart, by fixing the angle of the connecting shaft vertically, the shaft protrusion can be stored in the two-wheeled handy carry cart body, There is no problem in use as a two-wheeled handy carry cart dedicated to walking.

In order to suppress the up and down swinging at a certain height, a protruding part is provided on the upper part of the member provided with the rotating shaft of the connecting shaft so that the protruding part prevents the connecting shaft from jumping up and down. By bringing the portion and the connecting shaft together, the jumping up and down can be suppressed at a certain height, so that the load can be transported in a stable state.

Since the connecting shaft is fixed at any angle, the go and stop movement of the towing vehicle is directly transmitted to the two-wheeled handy carry cart, so that the operation of the bicycle and the two-wheeled handy carry cart is integrated. And stable traction can be achieved.

If the angle can be adjusted, even if the load placed on the two-wheeled handy carry cart is as long as a golf bag, it can be pulled and transported by setting the angle of the connecting shaft so that the shaft stands upright. become.

At the position of the upper part of the carry cart, a shaft 7 is provided, and a semicircular base 5 is provided with a member having a plurality of holes 3 oriented in different directions, on the opposite side. The same semicircular base is provided with a member on which several fixing nuts 6 that are symmetrical with respect to a hole that faces in different directions are mounted.

A connecting shaft 1 that enables one rotation between the left and right semicircular base members is provided, and the connecting shaft is located in a semicircular shape and overlaps with several holes at different angles. Are provided with holes 15 through which screw bolts pass.

Screw bolts at the three holes of the semi-circular member, the hole of the connecting shaft, the fixing nut provided in the semi-circular member on the opposite side, Insert 4 and tighten to secure.

A ring-shaped hook 9 is provided at the tip of the connecting shaft.

A rotating shaft 8 is provided at a position behind the ring-shaped hook at the tip of the connecting shaft.

The shape which fastens the connection shaft of a two-wheel-drive type handy carry cart is a pivotal cylindrical retainer 10.

The pivot of the fastener has a screw-type umbrella shape so that the connecting shaft does not come off, and an umbrella-type screw cover 12 is provided to widen the screw-type umbrella-type umbrella-shaped portion.

The semicircular base of the two-wheel-drive handy carry cart has several semi-circular bases with several holes facing in different directions. Screw bolts into the holes in the base plate, the holes in the connecting shaft, and the fixing nuts in the semicircular base plate, and tighten them.

Insert the ring-shaped hook at the tip of the connecting shaft into the cylindrical bracket on the rear axis of the bicycle, and turn and tighten the cylindrical bracket so that it does not come off the threaded umbrella lid.
