Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire and wheel carrier.

[0002]

2. Description of the Related Art In a tire service factory for large vehicles such as trucks and buses, vehicles to be maintained and maintenance equipment (balancer,
Changer, etc.) takes up a significant amount of weight. Therefore, in order to unmanned, labor-saving, and reduce labor of the tire wheel transfer work, an electric traction type or manual type tire wheel transfer cart is sometimes used. At this time, loading and unloading of the tire wheels to and from the trolley were performed by a power type such as an electric type or by manual power.

[0003]

However, if the loading and unloading of the tire wheels to and from the transport trolley is of a power type, the cost is increased. On the other hand, when performing work manually, the tire wheels of large vehicles sometimes exceed 100 kg, which put a considerable burden on workers.

That is, the loading of the tire wheels onto the tire wheel carrier can be relatively easily performed by rolling the tire wheels and providing inertia. However, the operation of dispensing the fixed tire wheels from the carrier is necessary. He needed considerable strength.

Accordingly, the present invention solves the above-mentioned conventional problems, and provides a tire-wheel transport trolley in which the loaded tire wheels can be easily dispensed and the burden on the operator can be reduced. The purpose is to:

[0006]

To achieve the above object, the present invention provides a base frame having a pair of front and rear vertical tire wheel fixing support frames and a plurality of wheels attached thereto.
A tire wheel dispensing member provided between the pair of support frame portions and pivotally attached to one end of the left and right ends of the base frame, and an operating arm portion provided in an upright state on the dispensing member; It has.

Further, the base frame has an opening for fitting the lower part of the vertically raised tire wheel between the pair of support frame parts, and the tire wheel dispensing member has a front edge of the opening and a tire wheel dispensing member. And / or a swing arm provided along the rear edge, and a tire wheel lifting rod provided at the tip of the swing arm.

In addition, a pair of tire wheel dispensing members arranged symmetrically in a plan view may be provided, or a horizontally projecting hook may be attached to one of the front and rear edges of the base frame.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail with reference to the drawings showing the following embodiments.

FIG. 1 shows an embodiment of a tire wheel transport cart according to the present invention. The tire wheel transport cart 1 has a rectangular base frame 2 for fixedly supporting a tire wheel.
And a pair of tire wheel dispensing members 6 and 6 attached to the base frame 2 and operation arms 7 and 7 provided on the dispensing member 6 in an upright state.

More specifically, the base frame 2 is provided with a pair of front and rear flanges 8, 8 and vertical tire wheel fixing support frames 3, 3, respectively.
Are fixed, and the flanges 8 are connected to form a rectangular opening 5.

A plurality of (four in the illustrated example) wheels 4 are provided on the back side of the corners of the flanges 8, 8, and a pair of horizontally projecting hooks are provided at the front edge. 13, 13 are attached. Further, as shown in FIG. 2, a pair of short horizontal shaft portions 9, 9 are provided on the front left side and the rear right end of the opposed inner surfaces 8a, 8a of the flanges 8, 8, respectively.

A pair of tire wheel dispensing members 6 and 6 are attached to the left and right ends of the base frame 2, and are arranged symmetrically along the periphery of the opening 5 in a plan view.
That is, the dispensing member 6 includes a swing arm 10 provided along the front edge 5a or the rear edge 5b of the opening 5 and a tire wheel lifting rod 11 provided at the tip of the swing arm 10. And it consists of

Then, as shown in FIG. 3, by inserting a hole provided at the base end of the swing arm portion 10 into the horizontal short shaft portion 9 of the base frame 2, the payout member 6 is attached to the base frame. 2 is pivotally attached to the swing arm. Also, the operation arm unit 7
It has a slightly bent lower end (as shown in FIG. 1), and an operating lever 12 is attached to the upper end. In addition, the lower end is bent so that the swing arm 10
Is fixed to the upper surface of the base end.

Next, a method of using the cart 1 will be described. First, as shown in FIG. 4, the flexible member 14 is attached to the hooking piece 13, and the towing vehicle C and the bogie 1 are connected. Next, the vertically raised tire wheel W is rolled toward the bogie 1 and the lower part of the tire wheel W is fitted into the opening 5,
The state shown in FIG.

Next, after the carriage 1 is pulled to a desired location, as shown in FIG. 5B, the operator pulls the operation lever 12 of the operation arm 7 in the direction of arrow A, and the tire wheel W The tire wheel W can be easily dispensed by being lifted upward by the lifting rod 11 abutting downward, and by swinging the swing arm 10 to incline in the dispensing direction.

Since the bogie 1 has a pair of tire wheel dispensing members 6, the tire wheel W can be dispensed in both left and right directions, and dispensed in a state where the tire wheel W is raised vertically. Therefore, it is convenient to attach it to a car.

The present invention is not limited to the above-described embodiment, and can be freely changed in design. For example, only one tire wheel dispensing member 6 may be attached to the base frame 2. Also,
In the case of one, it is preferable to provide a pair of swing arms 10, 10 along both edges of the front edge 5a and the rear edge 5b of the opening 5.
It is also preferable to provide holes at the left and right ends of the base frame 2 without providing the horizontal short axis portion 9 and insert the lower end of the operation arm portion 7 into the holes to pivotally attach.

[0019]

The present invention has remarkable effects as described below.

According to claim 1, as many as ten or more large tire wheels W used in large vehicles such as trucks and buses can be easily and safely paid out at desired positions. Repair, inspection and rotation of the tire wheel W can be reduced. Also, since it is a simple structure of a manual type, there is no cost.

According to the second aspect, the tire wheel W can be easily paid out in a vertically raised state.
Safe and convenient when working. Further, since the lever-type payout mechanism is used, the large and heavy tire wheel W can be paid out easily.

According to the third aspect, since the payout can be made in both the left and right directions, the tire wheel W can be paid out in a desired direction. According to claim 4, when the towing vehicle C is towed to a desired position, the flexible member 14 can be easily hooked,
The truck 1 and the towing vehicle C can be easily connected.
