Description

The invention relates to billiards, in particular to billiard tables intended for the game of "Russian pyramid", and can be used in billiard tables intended for the game of "snooker" and "carom".

A known billiard table containing a frame mounted on vertical supports, a rectangular tabletop horizontally located on the frame and equipped with sides with rollers and rubber shock absorbers, elements for attaching the sides to the tabletop, including bolts passed through end holes made in the sides and in worktops connected by means of threaded joints with fastening anchors installed in the worktop, as well as covering of the worktop and sides (05, patent Mo2391395, "Billiard table", NPK 273-6, MPK Ab6ZO 15/00, publ. 25.12.1945, statement 06/05/1942, analogue; 5, patent Mo2333709, "Means of fixing billiard table plates", NPK 273-6, MPK Ab3O 15/00, published 11/09/1943, application 06/05/1942, analogue).

The table top is made in the form of a set of several slabs made of natural stone.

Fastening anchors are installed with a specified step in the ends of the plates along the perimeter of the tabletop and are made with threaded holes located in the horizontal plane. The end holes in the sides are located coaxially with the fastening anchors. Fastening anchors are made with transverse holes that coincide with vertical holes made in the slabs of the tabletop. Fastening anchors are fixed in the tabletop slabs with the help of screws, which are passed through the vertical holes of the tabletop slabs and the transverse holes of the fastening anchors and fixed (screwed) into the subfloor of each tabletop slab. The slabs of the tabletop together with the sub-floor rest on the longitudinal and transverse slats (rails) of the frame and are connected to the latter with the help of bolts.

The disadvantages of the well-known pool table are the imperfection of the design of the fastening anchors and their installation in the tabletop, which reduces the reliability of attaching the sides to the tabletop.

This is explained by the fact that when the bolts are tightened, the cross-section of the screws occurs, which disrupts the attachment of the sides to the tabletop.

Violation of the attachment of the sides to the tabletop can also occur with strong repeated blows of billiard balls against the side of the billiard table.

A billiard table is also known, which includes a frame mounted on vertical supports, a rectangular tabletop, horizontally located on the frame and equipped with sides with rollers and rubber shock absorbers, elements for attaching the sides to the tabletop, including bolts passed through end holes made in the sides and in the tabletop, connected by means of threaded connections with fastening anchors installed in the tabletop, as well as the covering of the tabletop and sides (KO, patent Meo2108834, C1, "Professional billiard table", BMPK AbYEZO 15/00, publ. 04/20/1998, appl. 01.12.1995, analogue).

The table top is made in the form of a set of several plates made of highly filled composite material based on a polymer matrix.

For fixation, fastening anchors are formed in the end of the plates with a specified step along the perimeter of the tabletop during its manufacture. Fastening anchors are made with threaded holes located in the horizontal plane.

The end holes made in the sides for the bolts are located coaxially with the fastening anchors. The outer surface of the fastening anchors is smooth cylindrical.

The disadvantages of the well-known billiard table are the imperfection of the layout and design of the seats for the fixing anchors in the tabletop, which increases the labor intensity and reduces the reliability of attaching the sides to the tabletop.

This is caused by the fact that the fastening anchors must be installed very precisely (the deviation from the flatness of the tabletop in general should not exceed 100 μm) in the design position directly during the manufacture of the tabletop from highly filled composite material based on a polymer matrix.

In addition, due to the fact that the outer surface of the fastening anchors is made of a smooth cylindrical surface, their reliable adhesion to the worktop material is not ensured. Therefore, when the bolts are tightened, there is an axial shift of the anchors in the end holes of the tabletop, which causes a violation of their design position and a decrease in the strength of fixing the sides to the tabletop.

Axial displacement of the fixing anchors in the end holes of the tabletop can also occur when billiard balls hit the sides of the billiard table repeatedly.

The known closest to the invention in terms of the number of common features and the technical result achieved is a billiard table containing a frame mounted on vertical supports, a rectangular tabletop horizontally located on the frame and equipped with sides with rollers and rubber shock absorbers, elements for attaching the sides to the tabletop , which include bolts passed through the end holes made in the sides and in the tabletop, connected by means of threaded connections with fastening anchors installed in the tabletop, as well as covering the tabletop and sides (VI, patent for the invention Mo2138308, C1, "Billiard table A .M.

Basova", BMPK АЭ3015/00, 15/06, publ. 27.09.1999, statement 03/03/1999, prototype).

The tabletop is made in the form of a set of several slabs made of reinforced concrete or natural stone.

Fastening anchors are hammered with a given step in the ends of the plates along the perimeter of the tabletop and are made with threaded holes located in the horizontal plane. The end holes made in the sides for the bolts are located coaxially with the fastening anchors. For better adhesion to the countertop after the concrete has hardened, the outer surface of the anchors is wavy.

The disadvantages of the well-known billiard table are the imperfection of the layout and design of the seats for the fixing anchors in the tabletop, which increases the labor intensity and reduces the reliability of attaching the sides to the tabletop.

This is caused by the fact that for a tabletop made of natural stone, such fastening of the sides causes significant difficulties.

This is due to the fact that it is necessary to first make end holes in the ends of the tabletop, after which fixing anchors are installed in them with the help of concrete or another substance in the design position. After the concrete or other substance has hardened, the bolts are tightened while attaching the sides to the tabletop.

When the bolts are tightened due to the weak adhesion of the fastening anchors or the worktop with hardened concrete or another substance, their axial displacement occurs in the end holes of the worktop, which causes a violation of their design position and a decrease in the strength of the attachment of the sides to the worktop.

Axial displacement of the fixing anchors in the end holes of the tabletop can also occur when billiard balls hit the side of the billiard table repeatedly.

The task of the invention is to provide a decrease in the labor intensity and increase the reliability of fixing the sides to the table top by improving the layout and design of the seats under the fixing anchors in the table top.

The task is solved by the fact that in the pool table, which contains a frame mounted on vertical supports, a rectangular tabletop, horizontally located on the frame and equipped with sides with rollers and rubber shock absorbers, elements for attaching the sides to the tabletop, including bolts passed through the end the holes made in the sides and in the table top are connected by means of threaded connections to the fastening anchors installed in the table top, as well as the covering of the table top and sides, according to the invention, each fastening anchor is installed in a hidden hole made from the bottom of the table top at a distance from the end and located cross the end hole through which the bolt is passed, connected by means of a threaded connection to this anchor.

The given features of the invention are essential, because in aggregate they are sufficient to ensure operability and the solution of the given task, and each separately is necessary for the identification of the claimed technical solution.

Thus, the new set of general (known) and distinctive (new) essential features from the prototype, which characterize the improved pool table, is sufficient in all cases covered by the scope of legal protection, because it solves the task at hand.

The given features of the invention are not mandatory, but, in the opinion of the applicant, they are better and do not exclude the possibility of another equivalent performance of the pool table within the specified scope of the invention.

The cause-and-effect relationship between the set of essential features of the invention, including distinctive (new) in their interaction with general (known) features, in providing new technical properties of the object of protection, determined by the problem to be solved, is as follows.

Due to the fact that in the improved billiard table, each fastening anchor is installed in a hidden hole made from the bottom of the tabletop at a distance from the end and located diagonally to the end hole, through which the bolt, connected by means of a threaded connection to this anchor, is passed through, reducing the complexity and increasing reliability fixing the sides to the tabletop.

A reduction in the complexity of attaching the sides to the tabletop is achieved due to the fact that there is no need to use concrete or another hardening substance to monopolize the fastening anchors in the seating places of the tabletop.

An increase in the reliability of fastening the sides to the tabletop is achieved due to the fact that the improved location of the fastening anchors excludes their axial shift in the tabletop, does not cause a violation of their design position and ensures high strength of the fastening of the sides to the tabletop, both when the bolts are tightened and during strong repeated blows of billiard balls balls against the sides of the pool table. This is due to the fact that the fastening anchors reliably rest on the strong bridge of the tabletop between the hidden holes and ends made in it.

The pool table has other distinctive features that complement and characterize the invention in certain cases of its implementation and are used to improve its technical and consumer properties.

In the pool table, according to the invention, each fastening anchor can be made in the form of a round rod with a transversely located threaded hole.

This execution of fastening anchors is the most simple and technological option (option 1), because they can be manufactured from round rolled steel.

In the billiard table, according to the invention, each fastening anchor can be made in the form of a multifaceted rod with a transversely located threaded hole.

This execution of fastening anchors is another simple and technological variant of execution (option 2), because their manufacture can be carried out, for example, from hexagonal rolled steel intended for the manufacture of bolts and nuts.

With this version of the execution of the fastening anchors, the manufacture of transverse threaded holes in them is simplified.

In addition, due to the fact that the fastening anchors in both versions (options 1 and 2) and the hidden holes of the tabletop are tightly connected to each other by contacting surfaces, this significantly reduces the contact stresses between them when the bolts are tightened.

In the pool table, according to the invention, the hidden hole of each fastening anchor is closed with a plug made of a material that is easily destroyed, such as lead, babbitt or polymer material.

This improvement of the billiard table eliminates unauthorized access to the fastening elements, which significantly increases the reliability of fastening the sides to the tabletop and ensures stable working condition of the billiard table and its safe operation.

In addition, the mentioned plug fixes the fastening anchor in the design position during assembly, disassembly and transportation of the pool table.

Making the plug from a material that is easily destroyed, such as lead, babbitt or a polymer material, allows for easy removal and installation of the plug in the countersunk hole when replacing the fixing anchor.

In the following, the invention is explained by a detailed description of its construction with reference to the attached drawings.

In fig. 1 shows a pool table, general view, side view.

In fig. 2 shows a pool table, general view, top view.

In fig. C shows the section A-A in fig. 2.

In fig. 4 shows a section B-B in fig. 3, option 1.

In fig. 5 shows a section B-B in fig. 3, option 2.

The billiard table includes (fig. 1-5) a frame 1 (fig. 1) installed on vertical supports 2, a table top C (fig. 2) of a rectangular shape, horizontally located on the frame 1 and equipped with sides 4 (fig. 3) with rollers 5 and rubber shock absorbers 6, elements for fastening the sides 4 to the table top 3, which include bolts 7, passed through the end holes 8, 9, made in the sides 4 and in the table top 3, connected by means of threaded connections to the fastening anchors 10 installed in the table top 3 , as well as covering 11, 12 of tabletop C and sides 4.

Each fastening anchor 10 is installed in a concealed hole 13, made from the bottom of the tabletop Z at a distance from the end and located diagonally to the end hole 8, through which a bolt 7 is passed, connected to this anchor 10 by means of a threaded connection.

The distance y from the axis of the hidden hole 13 to the end of the table top Z is the value that ensures sufficient strength of the bridge 5 of the table top Z of the billiard table.

Each fastening anchor 10 can be made in the form of a round rod with a transversely located threaded hole 14 (option 1) (Fig. 4).

Each fastening anchor 10 can be made in the form of a multifaceted rod with a transversely located threaded hole 14 (option 2) (Fig. 5).

The hidden hole 13 of each fastening anchor 10 is closed by a plug 15 (Fig. 3), made of a material that is easily destroyed, for example, lead, babbitt or polymer material.

The plug 15 fixes the fastening anchor 10 in the design position during assembly, disassembly and transportation of the pool table.

The plug 15 made of easily destructible material is easy to remove and install in the hidden hole 13 when replacing the anchor 10, for example, when cutting the thread in the latter.

The features of the billiard table manufacturing and assembly technology are as follows.

Countertop C is made of natural stone or composite material.

For example, a blue or green billiard cloth of one of the world's famous manufacturers - Map Zitopov (Belgium) is used as a cover for 11, 12 tables C and sides 4.

During the manufacture of tabletop Z, the distance i is chosen from the condition of ensuring the design strength of each jumper 5 of tabletop Z, located between the countersunk hole 13 and its end. The design strength of the above-mentioned bridge of the worktop C is necessary for a reliable threaded connection of bolts 7 and fastening anchors 10 when attaching the sides 4 to the worktop 3.

Bolts 7 and fastening anchors 10 are made of high-strength steel.

Boards 4 are made of hard wood, such as oak, beech, ash or different types of mahogany.

When using an improved billiard table, it is ensured that the labor intensity is reduced and the reliability of fixing the sides 4 to the table top 3 is increased.

A reduction in the complexity of attaching the sides 4 to the worktop C is achieved due to the fact that there is no need to use concrete or another hardening substance for monopolizing the fastening anchors 10 in the seating positions of the worktop 3, as provided for in the prototype.

An increase in the reliability of fastening the sides 4 to the worktop C is achieved due to the fact that the improved location of the fastening anchors 10 excludes their axial shift in the worktop 3, does not cause a violation of their design position and ensures high strength of the fastening of the sides 4 to the worktop 3.

This is achieved both when the bolts 7 are tightened and when the billiard balls repeatedly hit the sides 4 of the billiard table.

This is due to the fact that the fastening anchors 10 reliably rest on the strong bridge 5 of the tabletop 3, formed between the concealed holes 13 made in it and the ends of the tabletop 3.

A pool table with an improved design can be repeatedly manufactured by an industrial method using known materials and modern technology at any pool table manufacturing enterprise.
