Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention raises one side of a cart with casters (1) slightly to disperse the load on a cart (4), and connects the carts with casters and the carts so that they are not easily displaced. It is characterized in that the bogie is moved lightly, accurately and easily by operating the car.

[0002]

2. Description of the Related Art Conventionally, carts with casters are supermarkets,
It is used in various sizes, shapes, and weights, such as baskets and shelves, for all kinds of delivery services, such as department stores, food, and light electricity. There are two types of casters, a fixed wheel and a universal wheel. Usually, four bogies (FIG. 5) or a combination of two universal wheels and two fixed wheels (FIG. 6) are mounted on a bogie. The bogie shown in Fig. 5 can be moved in any direction and is convenient. However, with a small amount of force, the bogie immediately rotates around one of the swivel wheels. Difficult, and some have a sturdy handle. Also, large or heavy bogies must start moving, and the axle direction of the free wheel that is facing apart must be turned in the direction of movement, requiring a large force, and the direction to move and the direction to start moving are not necessarily They do not match and have difficulty starting to move. In the bogie of FIG. 6, while pushing in the direction of the arrow from the free wheel side and pulling in the direction opposite to the arrow, the free wheel side is swung right and left around the fixed wheel, the bogie is rotated, and the bogie is moved to the target direction. It can be easily moved toward. However, the direction is not determined by the operation from the fixed vehicle side, and it is difficult to move. Also, you can not move in the direction perpendicular to the arrow, you can only move the trolley back and forth and move it little by little, just like moving the car, so move in narrow places such as in the elevator I have a hard time making it. On the other hand, the carrier (hand lift) shown in FIG. 7 is generally sold in various types such as a hydraulic type, a chain block type, and an electric type. The transport vehicle is composed of a fork portion for lifting the load, and a main body portion including two pairs of fixed wheels and a free wheel capable of controlling the direction. At about the center of the luggage, insert the carrier, raise the fork by hydraulic or other means, lift the luggage, and move the free wheel around the fixed wheel according to the principle of the bogie shown in Fig. 6 to accurately position the luggage. Can be moved to However, it lifts the entire load, so there is power in heavy loads. Also, because the entire load needs to be lifted, the transport vehicle is long, the turning radius around the fixed wheel is large, and to insert the transport vehicle near the center of the load, a certain amount of space is required in front of the load. Become. At present, trolleys with casters and carts are used for different purposes, and there is no cart to move carts with casters.

[0003]

SUMMARY OF THE INVENTION The present invention has been made so that a cart with casters can be moved by one person easily and accurately even in a narrow place.

[0004]

Referring to the drawings, a connecting plate (2) is provided at the bottom of a cart (1) with casters, and a supporting plate (5) is attached to the main body of a transport vehicle (4). Provide. At this time, the position of the support plate is such that the caster (3) of the bogie is slightly raised when the connecting plate hits the supporting plate by lifting the connecting plate with the fork (6) between the upper surface of the connecting plate and the lower surface of the supporting plate. To

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION A truck is inserted under a truck, and a connecting plate of the truck is sandwiched between a fork of the truck and a support plate.
When the fork is raised, the connecting plate is lifted, and one side of the bogie is also lifted, distributing the load of the bogie to the casters and the truck on the opposite side, and further pressing the connecting plate to the support plate to fix the bogie and the truck. , To be connected.

[0006]

Now, connecting plates are mounted on the four surfaces of the bogie of FIG. 5 and one surface of the fixed vehicle side of the bogie of FIG. 6, and the bogie is connected to the carrier. The free wheels (8) and the fixed wheels (7) and the free wheels (8) of the universal vehicle and the vehicle are reduced, and the load applied to each wheel is reduced, and the force required for movement is reduced. In addition, the force applied to the universal vehicle from the carrier through the connecting plate is transmitted in the same horizontal direction as the traveling direction of the carrier, and the axle of the universal vehicle changes its direction slightly in the same direction as the carrier. Light and easy to change direction. In addition, since the distance between the fixed wheel and the free wheel of the transport vehicle is short, the radius of rotation of the transport vehicle is small, and the vehicle rotates around the fixed wheel of the transport vehicle as a central axis, so that the bogie can be largely rotated by a small movement of the transport vehicle, Can be accurately and lightly moved even in narrow places. Also, since the axle of the bogie's free wheel is lightly oriented in the traveling direction of the transport vehicle, the bogie can be easily moved even if the number of free wheels is increased. Therefore, the loading load of the bogie, which is limited by the allowable load of the universal vehicle, can be increased. As the allowable load of the universal vehicle increases, the wheel diameter increases and the bogie increases, but the height of the bogie can be reduced by using a large number of universal vehicles with low allowable load. The present invention is particularly effective for a light truck, and in a flat light truck as shown in FIG.
There is no need to push and move the loaded luggage, and there is no need to carry a trolley even when there is no cargo. If the truck is heavy, the connecting plate is not always necessary, and when lifting one side of the truck,
It suffices if the movement of the transport vehicle is transmitted to the bogie as it is, and it works satisfactorily if the bottom of the bogie and the top surface of the fork do not easily shift in the horizontal direction. As a method of preventing the displacement, an elastic rubber plate, a resin plate or the like is stuck on the upper surface of the fork. Heavy trucks are mostly made of iron. Usually, the bottom of the truck is not a rigid flat plate, and an L-shaped angle or a C-shaped angle is used as a cross section of the bottom end as shown in FIGS. When you lift one side of the trolley,
Depending on the load, the end of the angle may bite into the rubber surface of the fork or dent the rubber surface. Since the force in the traveling direction of the cart is applied horizontally to the bottom of the cart, the rubber surface bites or the dent resists the misalignment in the horizontal direction. . In the case of a dolly with a reinforcing bar or a circular bar between legs, such as a bed on a caster in a hospital, the bar or round bar is lifted. Then, if you work with a frontage larger than the size of the square bar or round bar and lift one side of the bogie, the circular bar or square bar will fit along the processing groove and connect the transport vehicle and the bogie at a right angle and securely There are ways. In this way, the end shape of the bogie bottom and the processed shape of the upper surface of the fork may be matched. Also, a woody dolly such as plywood may be provided with several conical or pyramidal projections on the top surface of the fork. Even if the entire upper surface of the fork is formed as a conical or pyramid-shaped protruding surface, it is difficult to shift to some extent. Further, as shown in FIGS. 11 and 12, if the connecting plate is made hollow, the fork portion goes all the way, so that the lifting position may be anywhere on the fork. Therefore, the connection can be made at a position where the load protrudes from the cart.
