JP3019061U - A dolly that has four wheels arranged in a C shape and can run without removing the C-shaped groove. - Google Patents

Abstract

(57) [Summary] [Purpose] A simple structure that does not take up a lot of space during storage because it allows smooth movement when pulling the curtain with a horizontal pull-out curtain and storage device. [Structure] Attach the four wheels to the C-shaped base in the C-shape using the axle and assembly bolts. Attach the bottom plate to the bottom of the c-shaped base to reduce the inclination of the bar-mounting rod, and fix it with the base tightening nut so that it will not shake laterally between the upper and lower guide rails. A square base may be used instead of the C-shape. Since it runs continuously in the C-shaped groove, the entanglement prevention plates are attached to the front and back so that they do not get entangled. The distance between the front and rear wheels is set to be the minimum distance that does not fall from the C-shaped groove even when the platform swings, so that the vehicle body length is shortened as much as possible. The angle of the C-shape of the wheel is determined by the width of the C-shaped groove, the size of the base, and the size of the wheel.

2. Description of the Related Art There are two types of curtains, a hanging type and a horizontal type.

In the horizontal curtain type, C-shaped material of stainless steel or aluminum is used for the upper and lower rails.

There is a vehicle in which four moving wheels and four guide wheels are arranged for stable traveling in the C-shaped groove (reference picture 3).

Since the dolly has a complicated structure because eight wheels are arranged, the vehicle body length becomes long.

A long car body enables stable running, but a long space is required to store the car in one place

There are times when trouble occurs when traveling in a curved groove and smooth traveling cannot be performed.

[0007]

[Problems to be solved by the invention] It is necessary to continuously drive a large number of trucks for the purpose of use.

The body length is short due to the simple structure

Each car body does not get entangled in a narrow groove

[0010] For the intended use purpose, it should be placed vertically so that it does not get caught in the groove even if it is tilted.

[0011]

[Means for Solving the Problem] The C-shaped groove has a wide inner width, and moving wheels and guide wheels are required for stable traveling inside.

Conventionally, four wheels are arranged in front two and rear two in parallel (like a car), and two wheels are horizontally attached before and after that to eliminate left and right runouts and stabilize the wheels.

The wheel mounting base is made into a C shape and four wheels are mounted in a C shape.

When the wheels are formed into a C-shape, one wheel serves as the moving wheel and the guide wheel, and the corner of the wheel comes into contact with the groove wall to stop the left and right runout.

Since the corners of the wheels are in point contact, there is no contact resistance and smooth running is possible.

Some steps can be overcome depending on the size of the wheel

To prevent the entanglement between the bogie and the bogie, and the wheels and the wheels, an anti-entanglement plate was attached to prevent entanglement when running continuously.

Since the bolts for mounting the bar-mounting rods can swing laterally only on the upper side of the table (top of the C-shape), the bottom plate is attached to reduce the angle at which the bolts tilt

The front and rear wheel spacing is the minimum spacing that does not fall from the C-shaped groove even if the platform swings, and the vehicle body length is made as short as possible.

The angle of the C shape is determined by the width of the C groove, the size of the base, and the size of the wheel.

The C-shaped wheel mount may be formed into a square shape and the axle may be bent.

[0022]

[Operation] By arranging four wheels in a C-shape, the vehicle runs stably in the C-shaped groove.

Because the front and rear wheel spacing can be shortened, it does not get caught even in a curved groove

[0024]

[Embodiment] Used as a drawer for a horizontal curtain and as a guide wheel for a storage device

[0025]

[Advantage of the Invention] Since it is difficult to take a large space from the installation situation of the horizontal curtain device, it is advantageous that the vehicle body is short and the storage space is small.

Since each is provided with an anti-entanglement plate, each of them runs without getting entangled.
