Description

The invention relates to billiards, in particular to billiard tables designed to play the “Russian pyramid”, and can be used in billiard tables designed to play “snooker” and “carom”.

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, fastening elements of the sides to the tabletop, including bolts passed through end holes made in the sides and in the tabletop, connected using threaded joints with mounting anchors installed in the countertop, as well as coverings of the countertop and sides / US patent No. 2391395, “Billiard table”, NPK 273-6, IPC A 63 D 15/00, publ. 12/25/1945, declared. 06/05/1942, analogue; US patent No. 2333709, “Means of fastening of billiard table plates”, NPK 273-6, IPC A 63 D 15/00, publ. 11/09/1943, declared. 06/05/1942, analogue.

The countertop is made in the form of a set of several plates made of natural stone.

Fixing anchors are installed with a given step in the ends of the plates around the perimeter of the countertop and are made with threaded holes located in the horizontal plane. End holes in the sides are aligned with the mounting anchors. Fixing anchors are made with transverse holes matching the vertical holes made in the countertop plates. Fixing anchors are fixed in the countertop plates with screws that are passed through the vertical holes of the countertop plates and the transverse holes of the fixing anchors and are fixed (screwed) in the underframe of each countertop plate. The countertop plates, together with the underframes, are supported on the longitudinal and transverse frames (slats) of the frame and are connected to the latter by means of bolts.

The disadvantages of the known billiard table are the imperfection of the design of the mounting anchors and their installation in the countertop, which reduces the reliability of fastening the sides to the countertop.

This is explained by the fact that when tightening the bolts, a cross-section of the screws occurs, which violates the fastening of the sides to the countertop.

Violation of the fastening of the sides to the countertop can also occur with strong repeated blows of billiard balls on the board of the billiard table.

Also known is a billiard table containing a frame mounted on vertical supports, a rectangular tabletop horizontally located on the frame and provided with sides with rollers and rubber shock absorbers, fastening elements of 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 fixing anchors installed in the countertop, as well as coverings of the countertop and sides / RU patent No. 2108834 C1, “Professional billiard table”, 6 M K A 63 D 15/00, publ. 04/20/1998, declared 12/01/1995, analogue /.

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

For fixing, fixing anchors are molded into the ends of the plates with a given step along the perimeter of the countertop during its manufacture. Fixing anchors are made with threaded holes located in the horizontal plane. End holes made in the sides for bolts are located coaxially with the mounting anchors. The outer surface of the mounting anchors is made smooth cylindrical.

The disadvantages of the known billiard table are the imperfection of the layout and design of seats for mounting anchors in the countertop, which increases the complexity and reduces the reliability of fastening the sides to the countertop.

This is due to the fact that fixing anchors must be very accurately (the deviation from the flatness of the countertop as a whole should not exceed 100 microns) to be installed in the design position directly when manufacturing the countertop from a highly filled composite material based on a polymer matrix.

In addition, due to the fact that the outer surface of the mounting anchors is smooth cylindrical, their reliable adhesion to the tabletop material is not ensured. Therefore, when tightening the bolts, the axial displacement of the anchors in the end openings of the countertop occurs, causing a violation of their design position and a decrease in the strength of fastening the sides to the countertop.

The axial displacement of the fixing anchors in the end openings of the countertop can also occur during strong multiple impacts of billiard balls on the sides of the billiard table.

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, fastening elements of the sides to the tabletop, including bolts passed through end holes made in the sides and in the tabletop, connected by threaded connections with fixing anchors installed in the countertop, as well as coverings of the countertop and sides / UA declaration patent for invention No. 33000 A, “Billiard table ”, 6 IPC A 63 D 15/00, 15/06, publ. 02/15/2001, bull. No. 2001, stated 10/02/1998, analogue.

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

Fixing anchors are monolithic with a given step in the ends of the plates along the perimeter of the countertop and are made with threaded holes located in the horizontal plane. End holes made in the sides for bolts are located coaxially with the mounting anchors. For better adhesion to the countertop after hardening concrete, the outer surface of the mounting anchors is made wavy.

The disadvantages of the known billiard table are the imperfection of the layout and design of seats for mounting anchors in the countertop, which increases the complexity and reduces the reliability of fastening the sides to the countertop.

This is caused by the fact that for the countertops made of natural stone, such a fastening of the sides causes considerable difficulties. This is due to the fact that in the ends of the countertops, it is first necessary to make end openings, after which fixing anchors are installed in them with the help of concrete or another substance. After the hardening of concrete or other substance during fastening of the boards to the countertop, the bolts are tightened.

When tightening the bolts due to poor adhesion of the mounting anchors or countertops with cured concrete or other substance, they are axially displaced in the end openings of the countertop, causing a violation of their design position and a decrease in the strength of fastening the sides to the countertop.

The axial displacement of the fixing anchors in the end openings of the countertop can also occur with strong multiple impacts of billiard balls against the billiard table.

Known closest to the invention by the number of common features and 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, fastening elements of the sides to the tabletop, including bolts, passed through end openings made in the sides and in the countertop, connected by threaded connections to mounting anchors installed in the countertop, as well as coverings for countertops and sides / RU patent for the invention No. 2138308 C1, “Billiard table of A. M. Basov”, 6 MPK A 63 D 15/00, 13/00, publ. 09/27/1999, declared 03.03.1999, the closest analogue prototype /.

The countertop is made in the form of a set of several plates made of duralumin brand D16.

Fixing anchors are made in the form of nuts, which are pre-mounted (filled) in the plates of the countertop with a given step.

The disadvantages of the known billiard table are the imperfection of the layout and design of seats for mounting anchors in the countertop, which increases the complexity and reduces the reliability of fastening the sides to the countertop.

This is due to the fact that for duralumin countertops such fastening of the sides causes considerable difficulties. This is due to the fact that in the manufacture of plate tops, nuts are installed in the slots of the plates and poured with D 1 grade duralumin, which complicates the technology and increases the complexity of their manufacture.

In addition, when pouring nuts with duralumin in the plates, some of them may take a non-design position, in which they are skewed and the axes of the threaded surfaces of the nuts and bolts do not coincide, as a result of which their screwing is not ensured, which reduces the reliability of fastening the sides to the countertop.

It should also be noted that with repeated or excessive tightening of bolts, a violation of the integrity of the thread of some nuts may occur, and the latter must be replaced. And since the nuts are filled with duralumin, it is not possible to replace substandard nuts with new ones, which also reduces the reliability of fastening the sides to the countertop.

The objective of the invention is in the pool table by improving the layout and design of seats for mounting anchors in the countertop to reduce the complexity and increase the reliability of fastening the sides to the countertop.

The problem is solved in that in a billiard table containing a frame mounted on vertical supports, a rectangular tabletop horizontally located on the frame and provided with sides with rollers and rubber shock absorbers, fastening elements of the sides to the tabletop, including bolts passed through end holes made in the sides and in the countertop, connected by means of threaded connections with mounting anchors installed in the countertop, as well as the cover of the countertop and sides, according to the invention, each cre The peugeot anchor is installed in a countersunk hole made below the tabletop at a distance from the end and located crosswise to the end hole through which a bolt is connected, which is connected via a threaded connection to this anchor.

The above features of the invention are essential, since in the aggregate they are sufficient to ensure operability and solve the problem, and each separately is necessary to identify the claimed technical solution.

Thus, a new set of common / known / and distinctive / new / from the prototype of the essential features that characterize the improved pool table is sufficient in all cases to which the scope of legal protection applies, as it solves the problem.

The above features of the invention are not mandatory, but, according to the applicant, are the best and do not exclude the possibility of another equivalent implementation of a pool table within the specified essence of the invention.

A causal relationship between the set of essential features of the invention, including distinctive / new / when interacting with common / known / features, in providing new technical properties of the object of protection due to the problem being solved, is as follows.

Due to the fact that in the improved billiard table, each fixing anchor is installed in a countersunk hole made below the tabletop at a distance from the end and located crosswise to the end hole through which a bolt connected through a threaded connection to this anchor is passed, reduces labor intensity and increases reliability fastening the sides to the countertop.

Reducing the complexity of mounting the sides to the countertop is achieved due to the fact that there is no need to use duralumin for monoling fixing anchors in the seats of the countertop.

Improving the reliability of fastening the sides to the countertop is achieved due to the fact that the improved free location of the mounting anchors in countersunk holes eliminates their misalignment and mismatch of the axes of the threaded surfaces of the mounting anchors and bolts, does not violate their design position and provides high strength of fastening the sides to the countertop.

If necessary, substandard mounting anchors in a simple and affordable way can be easily replaced with new ones, which also increases the reliability of fastening the sides to the countertop.

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

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

This embodiment of mounting anchors is the simplest and most technologically advanced version (option 1), since their manufacture can be carried out from round rolled products.

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

This embodiment of mounting anchors is another simple and technologically advanced embodiment (option 2), since their manufacture can be carried out, for example, from hexagonal steel intended for the manufacture of bolts and nuts.

With this embodiment, the mounting anchors simplifies the manufacture of transverse threaded holes in them.

In addition, due to the fact that the mounting anchors in both versions (options 1 and 2) and countersunk countersunk holes are tightly mated with each other by contacting surfaces, this significantly reduces the contact stress between them when tightening the bolts.

In the pool table, according to the invention, the countersunk hole of each fixing anchor is closed by a cork made of easily destructible material, for example lead, babbitt or polymeric 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 a stable working condition of the billiard table and its safe operation.

In addition, the aforementioned cork fixes the mounting anchor in the design position during installation, dismantling and transportation of the pool table.

The implementation of the cork from easily destructible material, such as lead, babbitt or polymeric material makes it easy to remove and install the cork in the countersunk hole when replacing the mounting anchor.

The invention is further explained in the detailed description of its design with reference to the drawings.

Figure 3 shows a section aa in figure 2.

Figure 4 shows a section bB in figure 3, option 1.

Figure 5 shows a section bB in figure 3, option 2.

The billiard table contains (Figs. 1-5) a frame 1 (Fig. 1) mounted on vertical supports 2, a rectangular tabletop 3 (Fig. 2), horizontally located on the frame 1 and provided with sides 4 (Fig. 3) with rollers 5 and rubber shock absorbers 6, fasteners for fastening the sides 4 to the countertop 3, including bolts 7, passed through the end holes 8, 9, made in the sides 4 and in the countertop 3, connected by means of threaded connections to the fixing anchors 10 installed in the countertop 3, and also coverings 11,12 of table-top 3 and boards 4.

Each mounting anchor 10 is installed in a countersunk hole 13 made at the bottom of the countertop 3 at a distance t from the end and located crosswise to the end hole 8 through which a bolt 7 is connected, which is threadedly connected to this anchor 10.

The distance t from the axis of the countersunk hole 13 to the end of the countertop 3 is a value that provides sufficient strength of the jumper s of the countertop 3 of the billiard table.

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

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

The countersunk hole 13 of each mounting anchor 10 is closed by a plug 15 (FIG. 3) made of easily destructible material, for example, lead, babbitt or polymeric material.

Cork 15 fixes the mounting anchor 10 in the design position during installation, dismantling and transportation of the pool table.

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

Features of the manufacturing technology and assembly of a billiard table are as follows.

Worktop 3 is made of natural stone or composite material.

As a cover 11, 12 of the countertop 3 and sides 4, for example, billiard cloth of one of the world famous manufacturers - Iwan Simonis (Belgium) of blue or green color is used.

In the manufacture of countertops 3, the distance t is selected from the condition of ensuring the design strength of each jumper s of the countertop 3 located between the countersunk hole 13 and its end. The design strength of the mentioned jumpers of the countertop 3 is necessary for a reliable threaded connection of the bolts 7 and fixing anchors 10 when fastening the sides 4 to the countertop 3.

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

The sides 4 are made of hardwood, such as oak, beech, ash or various types of mahogany.

When using the advanced billiard table, laboriousness is reduced and reliability of fastening the sides 4 to the countertop 3 is increased.

The reduction in the complexity of fastening the sides 4 to the countertop 3 is achieved due to the fact that there is no need to use duralumin for monoling fixing anchors 10 in the seats of the countertop 3.

Improving the reliability of fastening the sides 4 to the countertop 3 is achieved due to the fact that the improved free location of the mounting anchors 10 in countersunk holes 13 eliminates their skew and misalignment of the axes of the threaded surfaces of the mounting anchors 10 and bolts 7, does not violate their design position and provides high strength fastening sides 4 to the countertop 3 when tightening the bolts 7.

This is achieved both by tightening the bolts 7, and with strong repeated blows of the balls on the sides 4 of the billiard table.

This is due to the fact that the mounting anchors 10 reliably rely on the strong jumper s of the countertop 3, formed between the countersunk holes 13 made in it and the ends of the countertop 3.

If necessary, substandard mounting anchors 10 in a simple and affordable way can be easily replaced with new ones, which also increases the reliability of fastening the sides 4 to the countertop 3.

The billiard table of improved design can be repeatedly manufactured industrially using well-known materials and modern technology at any enterprise producing billiard tables.
