Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is a caddy bag in which a golf club is carried and a disassembling cart is directly attached.

[0002]

2. Description of the Related Art Conventionally, a cart is brought to a golf course or rented at a golf course, and a caddy bag is carried on the cart for carrying.

[0003]

[Problems to be Solved by the Invention]

B. In the case of self-owned cart, the size occupied by the cart when not in use is an obstacle. B. In case of renting a cart, extra expense was required. Ha, without a cart, I had to carry a caddy bag for long distances during play.

The present invention aims to solve the above three items.

[0005]

In order to achieve the above object, the caddy bag of the present invention is provided with a wheel storage on the bottom surface, a frame is fixed on the back surface, and the frame is equipped with removable axles and wheels. A foldable axle support device and a towing arm are attached.

The axle support device can be attached to the frame at an appropriate position, but one point on each of the bottom surface of the wheel storage and the outer peripheral surfaces of the two wheels attached to the axle is on the same plane. If the position of the axle support device is determined as described above, the upright state of the caddy bag is stabilized because the caddy bag is supported upright by the bottom of the wheel storage and the three wheels when the caddy bag is installed upright.

A bag for storing the axle when disassembled may be attached to the side surface of the caddy bag.

[0008] It is preferable that the axle support device be in close contact with the frame and accommodated in a minimum space when the wheels are not used.

The towing arm should be closely attached to the frame when not in use.

When the tow arm is rotated 90 degrees toward the lower part of the caddy bag and fixed with bolts, the tow arm becomes a posture stabilizing leg of the caddy bag when the caddy bag is installed at an angle.

[0011]

[Operation] The procedure for preparing the wheels is as follows: first pull out and fix the axle support device that is in close contact with the frame, insert the axle into the bearing tube or the tubular shaft core of the hinge, and then attach the axle stopper to the axle. Project the protrusion from the stopper receiving hole and fix the axle, take out the wheel from the wheel storage and insert it into the axle, tighten the bolt attached to the wheel, rotate the towing arm closely attached to the frame and bolt it to the desired angle. Preparation is completed by fixing with.

Due to the action of the stepped wheel support which has the same inner diameter and is attached to the wheel and the stepped axle at both ends,
The wheels are prevented from moving toward the center of the axle, and the bolts attached to the wheel supports are tightened to prevent the wheels from falling off the axle.

The presence of the wheel supports reduces the friction between the axle and the wheels.

Since the present invention is configured as described above, it has the following effects.

By attaching the cart directly to the caddy bag, there is the convenience that a heavy caddy bag can be carried by the cart at any place.

Since it is a disassembling cart, it has a compact size that is almost the same as the volume of the caddy bag used conventionally when disassembling.

By attaching the wheel storage to the bottom surface of the caddy bag, the caddy bag serves as a posture stable maintaining stand when the caddy bag is installed upright.

Since the towing arm is a rotary type, the main arm and the auxiliary arm can be adjusted to freely expand and contract and angle with respect to the frame, and it also serves as a posture-maintaining leg when the caddy bag is installed diagonally, and when not in use, the frame is used. To make the caddy bag compact.

The axle is fixed to the axle supporting device simply by protruding the protrusion of the axle stopper into the stopper receiving hole,
It simplifies cart assembly.

The presence of the wheel receiver in the wheel simplifies the structure of the axle and reduces the friction of the wheel on the axle.

Since the five types of axle support devices shown in the drawings are all foldable, the assembly is simplified and the caddy bag is made compact when the wheels are not used.
