Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf bag with wheels.

[0002]

[Prior Art]

 Generally, a golf bag does not have a wheel for moving itself, but a method of carrying it around the shoulder or carrying it by hand is often used. However, since the contents of the golf bag is a club set made of iron, the weight of the golf bag is considerable, and the weight of the golf bag is heavy when it is transported from a passenger car to a golf course or driving range or when using a train or the like. It was a burden to carry the bag.

Further, to carry a golf bag on a golf course, it is common to use a carry for towing. However, since it is a carry with large wheels on a steel frame, the whole weight is heavy and it makes you tired when towing.It is also difficult to operate because it is large and there is a place to store the cart at the golf course. There was a problem such as taking. In addition, in the case of overseas golf courses, there are places where there is no carry.

Conventionally, as a method for solving such a problem, the following golf bag with wheels has been devised. As a first conventional example, as in Japanese Utility Model Laid-Open No. 54-48773, casters and support bars are vertically attached to the back side of the bottom of the golf bag.

Further, as a second conventional example, as in Japanese Utility Model Laid-Open No. 55-180462, a caster having a threaded rod is attached to the upper part of the bearing from a slanting downward direction, and a recessed part is provided on the bottom body of the golf bag. It is deeply screwed.

Further, as a third conventional example, as in Japanese Utility Model Publication No. 60-39024, two rods having a car at one end are built in the bottom of a golf bag, and a string is pulled to draw the car body. It is possible to take in and out.

[0007]

[Problems to be solved by the device]

 In the first conventional example described in the prior art, since the ground contact area is small when the golf bag is placed upright, there is a problem that the proportion cannot be maintained when the ground is soft or uneven. However, there is a problem that the golf bag moves by itself when it stands on an inclined surface, and a problem that the overall height of the golf bag increases.

In addition, in the second conventional example, in the case of a circular golf bag, there is a problem that the stability of the towing is poor because the vehicle wheel spacing is not so long due to the configuration, and the directionality because it is a caster There is no straightness when towing, and the problem is that if you try to pull on the lawn with a normal caster, the golf bag will sink into the lawn, the lawn will be marked on the lawn and the bottom will slip. I had.

Further, in the third conventional example, due to the structure in which the rod is built inside the bottom, the golf club storage space at the bottom is eliminated, and as a result, the overall height of the golf bag becomes high, Since the left and right rods cannot be integrated, the rigidity becomes insufficient during towing and becomes unstable. Especially, in the case of a circular golf bag, the state in which the wheels are pulled out is almost Since each wheel has a different shape, the traveling direction of each wheel is different, and there is a problem in that there is no straightness and operability is poor. The present invention addresses all of these problems.

[0010]

[Means for Solving the Problems]

 The first means of the present invention for solving the above problems is to provide a wide cylindrical wheel for movement near the end of the bottom of the golf bag. The second means is constructed so that the cylindrical wide wheel does not project downward from the bottom surface when the golf bag is placed upright. The third means is to provide a cut portion at the corner of the mounting side of the cylindrical wide wheel. The fourth means is to slightly increase the outer diameter of a part of the cylindrical wide wheel. The fifth means is to make the cylindrical wide wheel into a barrel shape. The sixth means is to provide a groove portion along the axial direction on the peripheral wall of the cylindrical wide wheel. The seventh means is such that the cylindrical wide wheel is slidable in the axial direction, and the left and right cylindrical wide wheels can be moved outward. The eighth means is to allow a cylindrical hollow wheel to be fitted onto a cylindrical wide wheel so as to be slidable in the axial direction, so that the left and right wheel widths can be varied.

[0011]

[Action]

 The action of the first means is to widen the ground contact area of the wheel to prevent the wheel from sinking on the grass which tends to sink, and when the golf bag is tilted, only the cylindrical wide wheel is used on the road surface or on the grass. It makes it possible to pull the golf bag by making a state of contact with the top.

As the action of the second means, it is possible to make contact with the bottom surface of the golf bag, so that even when the ground is soft or there is unevenness, it is possible to maintain the balance and when it stands on an inclined surface. However, it will not move by itself, and the problem that the overall height of the golf bag will increase will be solved.

The operation of the third means is to secure the vehicle height when the golf bag is tilted during towing, and to eliminate the ground contact at the corner portion of the golf bag on the side where the cylindrical wide wheel is mounted.

The operation of the fourth means is to reduce the ground contact portion on the road, improve the operability during towing on the road, and reduce the rolling noise of the wheels.

As with the fourth means, the action of the fifth means also reduces the ground contact portion on the road, so that the operability during towing on the road is improved and the rolling noise of the wheels is reduced. Of.

The action of the sixth means is to eliminate the slip on the lawn and to make the roller rotate smoothly.

The operation of the seventh means is to widen the wheel spacing, thereby improving the stability during towing on the lawn.

The operation of the eighth means is to widen the wheel width and the ground contact area, thereby further suppressing the sinking on the lawn and improving the stability during towing.
