JPH11342848A - Member for shock absorber of handcart - Google Patents

Abstract

PROBLEM TO BE SOLVED: To eliminate such nonconformities, as a member for shock absorber cannot be moved to the position being damaged according to the positions of the damage even through the damage positions of the hand-cart and the baggage are made different according to the condition of the road and the like where the handcart is used, so as to prevent to exercise the role as the shock absorber member, and many metal members are used to install near the wheel of the push handle and the like to make the weight heavier, and the structure complicated, to necessitate the time and the labor for its installing work. SOLUTION: A locking hole 1a is provided at the center of a main body 1 which consists of a flexible material, and a cutout part 2 to hit to the locking hole 1 is provided from the side part of the main body 1. As a result, the locking hole 1a can be force-opened. Furthermore, a close contact means 3 to contact closely the cutting parts opposing to the cutout part 2 may be provided.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shock-absorbing member attached to a cart or other handcart used for carrying loads in factories, warehouses, distribution centers and the like.

[0002]

2. Description of the Related Art Conventionally, in factories, warehouses, distribution centers and the like where it is essential to carry luggage, a wheelbarrow for carrying luggage is indispensable.

By the way, in these places, goods are often transported by a wheelbarrow in a relatively narrow passage, and in general, the direction of movement of a wheelbarrow cannot be accurately controlled. In addition, other luggage and equipment may be placed in the aisle, and the aisle is not always well-organized.

[0004] Therefore, when using a handcart, the carriage is moved while colliding with a load on the side wall of the passage or the luggage or equipment placed on the passage.

[0005] However, if the wheelbarrow collides with the side wall of the passage, the luggage, or the equipment while moving, there is a possibility that these may be damaged or damaged. Moreover, there is a possibility that the luggage placed on the wheelbarrow may be damaged.

[0006] Therefore, various types of shock absorbing members have been attached to this type of wheelbarrow near the wheelbarrow or wheels.

[0007]

However, since the shock absorbing member of the above-described conventional wheelbarrow cannot be easily moved from the position where it is mounted, it is difficult to move the shock-absorbing member according to the situation of the passage using the wheelbarrow. However, even if the part where the wheelbarrow or the luggage is damaged is different, the part cannot be moved to a position corresponding to the part, and there is a problem that the part may not function as a shock absorbing member.

Further, the conventional shock absorbing member of a wheelbarrow uses a large number of metal members to be attached to the vicinity of a handwheel or a wheel, so that the problem that the weight becomes heavy and the structure is complicated. Therefore, there has been a problem that it takes time and effort to attach the device to a wheelbarrow.

Accordingly, the present invention is to solve the above-mentioned conventional problems, and can easily move the position to be mounted on the wheelbarrow, and is light in weight, and the work of mounting on the wheelbarrow is very easy. An object of the present invention is to provide a shock-absorbing member that can be easily performed.

[0010]

For this purpose, a shock absorbing member of a pushcart according to the present invention is provided with a locking hole 1a at the center of a main body 1 made of a flexible material, and the locking hole 1a is formed from the side of the main body 1. By providing the notch 2 which reaches the locking hole 1a, the locking hole 1a can be pry open.

The shock absorbing member of the handcart according to the present invention may be provided with a contacting means 3 for keeping the cuts 2a, 2a facing the notch 2 close to each other.

Further, the shock absorbing member of the handcart according to the present invention has surface adhesive fasteners 10a, 10b at both ends.
Can be combined with the fastening band 10 for drop prevention.

Further, the shock absorbing member of the handcart according to the present invention is provided with a hole diameter adjusting member 12 having a locking hole 12a at the center and a cutout 13 reaching the locking hole 12a from the side. The main body 1 may be fitted into a locking hole 1a.

[0014]
