Abstract

The top plate of a slate billiard table, which is heavy and difficult to carry and requires technology, cost and time for assembly adjustment, is reduced in weight, and unpleasant impact sound associated with weight reduction is suppressed.
SOLUTION: A honeycomb core panel in which an aluminum surface plate 1a and a back plate 1b are bonded and fixed to the upper and lower surfaces of a honeycomb core 2 made of a light alloy such as aluminum is used as a base, and the surface plate 1a has a thickness of 2 mm. This is a billiard table top plate provided with a buffer material 3 made of synthetic rubber and having an aluminum surface plate 4 fixed in close contact with the buffer material 3, and has the same rigidity as a top plate made of slate. ing. Light weight and high rigidity make it easy to transport and assemble and can be assembled and adjusted in a short time. Even when the ball collides with the cushion and bounces back, even if it collides with the top plate 1, the shock is absorbed by the cushioning material 3, and the impact sound does not resonate in the cavity of the honeycomb core 2 to produce an unpleasant sound.

Description

  The present invention relates to a billiard table top plate that has been conventionally made up of a heavy weight slate plate and is light in weight and is convenient for transportation and storage.

  The billiard table top plate generally uses a slate plate (stone) because the surface of the table requires high-precision flatness. The slate has a relatively large specific gravity of 2.7 and requires a sufficient thickness to ensure flatness. The total weight of the billiard table is 350 kg to 600 kg per unit including the frame. Therefore, it was not easy to carry or move.

  Slate is a fragile material, and if the entire billiard table is composed of one slate, it can be lifted so that force is evenly applied to the entire plate, but if it is lifted with the force biased, it will only In order to prevent breakage of the slate plate, the entire billiard table is not composed of a single slate, but one piece is divided into about 90 kg, and these are joined together It constitutes a pool table.

  Since multiple slate plates are joined together, each slate plate is placed on the frame for assembly work, but the height is adjusted using wedges so that there is no step at the joint. The joints are flattened with putty, and assembling and adjusting the divided slate plates requires skilled workers, which is time consuming and expensive.

As mentioned above, since the billiard table is required to be delicately assembled, once the assembled billiard table is moved, subtle deviations occur and the flatness of the billiard table is lost, or there is a step in the seam. Since it occurs, readjustment is necessary, and it can be said that it is almost impossible to move the billiard table that has been adjusted.
For this reason, if a billiard game tournament or a workshop is to be held for a short period of time, transportation and installation of the billiard table and assembly adjustment will be expensive and time consuming, so it has not been possible to implement it easily. For this reason, the billiard table requires a dedicated space, so it can be installed for a short period of time in a hall or gymnasium, which is a multipurpose space that many people use for different purposes. It was almost impossible to take out, adjust and play.
When a billiard table can be assembled and installed in a short time without the need for skilled technicians to assemble, install and adjust the billiard table for a short period of time and disassembly and removal after use, many Although people can easily enjoy billiards, it has been difficult due to the above circumstances.

US Pat. No. 5,830072

A billiard table using a slate is over 300 kg even if it is small, is not easy to transport, and requires a skilled engineer for assembly and adjustment, and thus requires cost and time. A billiard table that has been reduced in weight has been proposed in place of the heavy slate billiard table, but the billiard table is not sufficiently flat and has the disadvantages of being distorted over time. A high-strength, high-rigidity pool table has not been realized.
An aluminum honeycomb core panel is known as a lightweight, high-strength, high-rigidity member. The aluminum honeycomb core panel has been developed as an aircraft structural material, and is formed by sandwiching a hexagonal core of a light metal thin plate such as aluminum between upper and lower panels. Aluminum honeycomb core panels have been used as building materials mainly in high-rise buildings due to their light weight, high strength, and high rigidity.
When this aluminum honeycomb core panel having light weight, high strength and high rigidity is used in place of a slate as a billiard table top plate, it has been found that there are the following disadvantages.

Billiard is a game in which a ball is hit by a cue and rolled, the ball collides with a wall provided around the top plate, that is, a cushion rail having a repulsive force, and the ball is rebounded by the repulsive force in various games. If the aluminum honeycomb core panel is simply used as a top plate for a billiard table as a substitute for a slate, when the ball hits the cushion rail and returns, it is as big as hitting a drum that does not come out on the top plate of the slate. A hitting sound is generated and the atmosphere of the billiard hall is broken. Initially, the mechanism of the impact sound generation was unknown and countermeasures could not be taken, but various experiments were repeated, and when the ball bounces back on the cushion rail, the repulsive force of the cushion rail acts downward and the ball is It was presumed that a large sound was generated when the impact sound of the ball hitting the top plate at this time resonated in the hollow portion of the honeycomb core.
The object of the present invention is to reduce the weight of the billiard table top by using the honeycomb core panel and to exhibit the performance required for the billiard table, that is, the advanced technology of a professional billiard player, as with the conventional slate top plate. An object of the present invention is to provide a billiard table top plate that can eliminate the loud sound when the ball rebounds from the cushion rail.

A billiard table top plate in which a light metal surface plate is closely fixed to a top surface plate of a honeycomb core panel in which a light metal upper surface plate and a lower surface plate are fixed on both sides of the light metal honeycomb core through a cushioning material. It is.
The light metal is aluminum, aluminum alloy, titanium, or duralumin, and the buffer material is a rubber sheet, a soundproofing / absorbing material in which felt is impregnated with asphalt, or a hollow sphere having a diameter of 5 μm to 350 μm in a silicone gel base material. Is a buffer material in which is dispersed, or a combination of them in multiple layers.
Moreover, the surface plate made of light metal is a billiard table top plate having a thickness of 3 mm or more.

The billiard table top plate of the present invention has a light metal honeycomb core panel and a top plate made of light alloy with a cushioning material made of rubber sheet or the like interposed between the light metal surface plates so that it is lightweight, high strength, Because it is highly rigid, the weight of the billiard table top plate can be reduced to one-third compared to the slate, and it is easy to transport and assemble, and can be assembled easily even by a skilled engineer. became.
In addition, since a cushioning material such as a rubber sheet is interposed on the honeycomb core panel and the light alloy surface plate is fixed, the impact when the ball bounced off by the cushion rail hits the surface plate is absorbed. Generation of sound is suppressed, resonance due to the space of the honeycomb core does not occur, and generation of a loud hitting sound is prevented.
And because the top plate is high-strength and high-rigidity, there is no quiet ball rolling and no impact sound on the top plate when rebounding from the cushion rail, which is the same technology as the slate top plate, jumping is an advanced technology Shots, masses, and other shots are now possible, and all billiard games can now be handled, making it possible to play with the same feeling as a billiard table with a slate board.
In addition, since the top plate can be significantly reduced in weight, the strength of the frame that supports the top plate can be lowered from the billiard table of the slate top plate, so parts other than the top plate can also be reduced in weight. In addition, the billiard table structure can be simplified, so the manufacturing cost can be reduced, and the support height of the top plate at the four corners of the billiard table that supports the top plate can be adjusted without requiring craftsmanship for assembly and installation. By simply doing this, the level of the billiard table can be adjusted, making assembly and installation easy.

Sectional drawing of the billiard table top plate of this invention. The perspective view which fractured | ruptured partially the billiard table top plate of this invention.

  FIG. 1 is a cross-sectional view of a billiard table top plate 1 of the present invention. An aluminum core panel 1 in which aluminum or duralumin plates 1a and 1b having a thickness of 3 mm are fixed to the top and bottom of an aluminum honeycomb core 2 by bonding. A rubber sheet 3 having a thickness of 2 mm is closely attached to the surface of the upper plate 1a. Furthermore, a top plate 1 of a billiard table is obtained by bonding and fixing a surface plate 4 of an aluminum plate having a thickness of 3 mm on the rubber sheet 3.

  The thickness of the upper and lower plates 1a and 1b of the aluminum core panel 1 is set to 3 mm or more so that sufficient rigidity can be obtained. Further, the surface plate 4 is used as a billiard table with a cloth stretched on its surface. However, since the ball may drop and give an impact, it needs to have a thickness of at least 3 mm.

The rubber sheet 3 may be synthetic rubber or natural rubber, but if the thickness is 2 mm or less, the impact force is generated because the impact force is generated by colliding with the surface plate 4 by the repulsive force of the cushion rail. Has a thickness of 2 mm or more. Alternatively, a plurality of rubber sheets may be stacked to have a predetermined thickness as a multilayer.
The same effect can be obtained by using a cushioning material in which fine hollow spheres are dispersed in a silicone substrate as a rubber sheet 3 to suppress the generation of impact sound.
