SOLUTION: This roulette rack is constituted so as to hold the roulette A in a horizontal state by disposing three studs 1 to the vertex positions of a virtual approximate equilateral triangle, forming a female screw part 2 to at least one of the upper and lower ends of the stud 1, screwing an adjusting male screw 4 onto the female screw part 2 and freely adjustably forming the length of the stud 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roulette stand for holding a roulette horizontally.

[0002]

2. Description of the Related Art Conventionally, a horizontally adjustable mount has been used to hold a roulette wheel in an absolutely horizontal state.

In this mount, a table is fixedly attached to the upper ends of four legs, an adjusting bolt is projected from the lower side of the round table to the upper surface, and the outer bottom surface of the roulette is placed and fixed on the upper end of the adjusting bolt. The horizontal adjustment of the roulette was done by rotating the adjusting bolt.

[0004]

However, the roulette rack has the following drawbacks.

(1) When placing the lower ends of the four legs on the floor surface, it is troublesome to adjust the lower ends of the four legs so that there is no play between the floor surfaces. Adjustments held in absolute level do not work.

(2) Since the round table and the pedestal are made of steel, they are heavy and are inconvenient to move and carry.

(3) There is no smart appearance due to the four legs,
The existence of the round table made me feel uncomfortable.

(4) Since the pedestal does not have a function of absorbing vibration, it is difficult to hold the roulette stably.

[0009]

In order to solve the above-mentioned problems, the present invention provides three pedestals at the apex positions of a virtual substantially equilateral triangle, and at least one of upper and lower ends of the pedestal has a female base. A threaded portion is formed, and an adjusting male screw is screwed onto the female threaded portion so that the length of the pedestal can be adjusted so that the roulette is held in a horizontal state.

A vibration absorber is connected to at least one of the upper and lower ends of the pedestal.

In addition, the three pillars are formed in a hollow shape having an opening at the upper end, and are connected to each other by three hollow horizontal rods so that a fluid is supplied to the hollow portions of the pillars and the horizontal rods. In order to fill and to follow the vertical movement of the fluid surface, the fluid surface is provided with legs for covering.

Moreover, the adjusting male screw connected to the upper end of the pedestal, the vibration absorber or the upper end of the leg body and the fitting concave member attached to the bottom surface of the roulette can be fitted freely.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION The roulette stand according to the present invention is
The three pillars are arranged at the vertices of a virtual equilateral triangle, and are connected to each other by three horizontal rods.

A female screw portion is formed on the upper end of the pedestal, and an adjusting male screw is screwed onto the female screw portion, while a female screw portion is formed on the lower end of the pedestal and is raised on the base. It is configured so that it can be screwed into the installed bolts, and the pedestal can be expanded and contracted.

Further, a tenon is formed at the upper end of the adjusting male screw, and the tenon can be fitted in a fitting recess for fitting attached to the lower bottom surface of the roulette.

With the above construction, the bolts at the lower ends of the pedestals can be adjusted vertically with respect to the floor surface, and the adjustment male screws at the upper ends of the pedestals can be used to horizontally adjust the roulette.

Therefore, a large inclination or a drop with respect to the floor can be adjusted at the lower end of the pedestal, and fine horizontal adjustment can be performed at the upper end of the pedestal, so that desired horizontal holding adjustment can be made at the upper and lower ends of the pedestal. Since this can be done, the adjustment work can be performed efficiently.

Furthermore, since the pedestal is arranged in a triangular position located at the top of the virtual substantially equilateral triangle, adjustment with the floor surface,
Adjustment with the lower bottom surface of the roulette is more
This can be done easily, and each of the three pedestals will be directly acted upon in the vertical adjustment operation, which has the effect of greatly contributing to the efficiency of the adjustment work.

Further, the roulette stand according to the present invention is one in which a vibration absorber such as a spring or a damper is connected to at least one of the upper and lower ends of the pedestal.

Even if the roulette on the roulette stand vibrates, the vibration can be absorbed.

Further, the roulette stand according to the present invention has three pedestals arranged at the apexes of a virtual substantially triangular shape, and each pedestal is
It is formed in a hollow shape with an opening at the upper end, and is connected and connected to each other by three hollow horizontal rods at the bottom of the pedestal, and the hollow portion of the pedestal and horizontal rod is filled with fluid such as water or oil. is there.

Moreover, the lower end surface of the leg is brought into contact with the fluid surface to cover it, and follows the vertical movement of the fluid surface,
The legs are designed to move up and down.

Then, the fluid filled in the hollow portion of the pedestal and the horizontal rod balances between the three pedestals, and the fluid moves between the pedestals, whereby the roulette can be held in an absolutely horizontal state, and Due to the viscosity of the fluid, the vibration of the roulette can be absorbed and the roulette can be held stably.
