Abstract

PURPOSE: To move the dolly light-heartedly with an easy posture maintained by releasing brake equipment after a cargo has been rested on a base plate with casters braked by the brake equipment, and moving the dolly by pulling a handle engaged with a support piece. CONSTITUTION: Four casters 10 are mounted on a base plate 1 on which a cargo is rested, at each area close to the four corners of its bottom surface. Besides, a support piece 7 for mounting a handle 15, which can lock a ring shaped locking piece 18 at the tip end section of the handle 15 when the dolly is to be moved, is formed at the forward end center section of the base plate 1. Moreover, brake equipment 11 is installed on the bottom surface of the base plate 1 in such a way that an operation lever 12 is extruded outward out of the outer circumferential section of the base plate 1, and is used in selecting an interception of the rotation of the caster 10 or its continuous rotation. After a cargo 20 has been rested over the base plate 1 with the caster 10 braked by the brake equipment 11, the brake equipment 11 is then relased, the handle 15 is locked on the support piece 7, and the dolly 19 is thereby moved.

In the embodiment, one caster 10 is added, and when the caster 10 is added in this way, the cart 19 that can reliably prevent the base plate 1 from bending even if it is a thin plate material 19
Can be C.

[0018]

As is apparent from the above description, the following effects can be obtained in the present invention.

(1) A base plate on which a packed baggage such as a cardboard box can be placed, at least four casters attached to the base plate near the four corners of the bottom face, and the center of the top end of the base plate. And a handle mounting support piece that is formed so as to project downward on the base portion and that can lock a ring-shaped locking piece at the tip of the handle during movement, and an operating lever on the bottom surface of the base plate. Since it is configured with a brake device that can prevent rotation of the caster mounted so as to project outward from the outer peripheral portion and can be selected rotatably, it is a support for mounting the handle when the truck is moving. A handle can be attached to the piece and pulled to move. Therefore, the carriage can be easily moved in a comfortable posture.

(2) According to the above (1), since the support piece for mounting the handle may be formed on the base plate, it is easy to manufacture and can be manufactured at low cost.
