Description

This technical solution relates to control and measuring equipment, and more specifically to devices for monitoring the linear and angular parameters of the billiard table pocket corridor, with dimensions of 12, 10, 9, 8 and 7 feet for Russian billiards.

Known, for example, is the pocket pattern (https://www.sites.google.com/site/poolbuilding/snuker_ip) for snooker. The disadvantages of this solution include the need to use a separate template for each type of pocket.

The task to be solved by the claimed technical solution is the creation of a universal device (template) that provides control of interconnected parameters of the corridor of billiard pockets in three-dimensional space.

The technical result of the claimed utility model is the ability to use a universal device to control the parameters of the corner and central pockets of billiard tables of various sizes.

This technical result is achieved due to the fact that the device for controlling the geometrical parameters of the pockets consists of two movable parts connected with a tenon-groove, each of which represents a mirror image of the contour of the pocket corridor, and a replaceable plate installed between the moving parts, while at one end each of the parts repeats the mirrored contour of the pocket corridor of the central pocket, and from the opposite end repeats the mirrored contour of the pocket corridor of the corner pocket.

The utility model is illustrated by drawings. In FIG. 1 shows a general view of the device for controlling the geometric parameters of the pockets, in Fig. 2 is an exploded isometric view of the template with the installed template plate. In FIG. 3 view of template with template plate in closed position. In FIG. 4 shows the position of the template in the corner pocket with the template plate installed. In FIG. 5 shows the position of the template in the center pocket with the template plate installed. In FIG. 6 shows the position of the template in the central pocket.

The device (template) for controlling the geometrical parameters of the pockets (Fig. 1) consists of two parts (1) and (2) movably connected with the tongue and groove, each of which represents a mirror image of the pocket corridor. A replaceable plate (3) (Fig. 2) is installed between the moving parts, the dimension of which allows you to adjust the target within 70-72 mm for the corner pockets and 80-82 mm for the central pockets of the billiard table.

The existing plate sizes have the following correspondence:

1) Plate 70/80 - the alignment of the corner pocket of the table is 70 mm, the central one is 80 mm, the size of the plate in this variant is 213 × 35 × 6 mm.

2) Plate 71/81 - the alignment of the corner pocket of the table is 71 mm, the central one is 81 mm, the size of the plate in this variant is 213 × 35 × 7 mm.

3) Plate 72/82 - corner table 72 mm, central 82 mm, the size of the plate in this variant is 213 × 35 × 8 mm.

The inventive template can be used both for assembling a billiard table and for controlling the main parameters of the corner (Fig. 4) and central pockets (Fig. 5). The split type of the template allows you to dismantle the template from the pocket without disturbing the geometry of the pockets. To do this, it is enough to remove the template plate and close both parts of the template. In the closed position, both parts of the template fit into each other according to the type of tenon-groove connection, and the template easily and without disturbing the geometry leaves the central or corner pocket.

After setting the sides of the corner pockets will have the same linear and angular dimensions. The central pockets will have the same linear and angular parameters. This product allows you to obtain the required standards for the accuracy of the geometric parameters of the pockets (FBSR standard. The main technical requirements for tournament tables and equipment for Russian billiards by the Russian Billiard Sports Federation).

The flare angle of the template for the corner pockets is 10 degrees from the horizontal, the flare angle of the template for the center pockets is 8 degrees from the horizontal. The angle of expansion of the corner and central parts of the template to the vertical is 3 degrees. The template repeats the radii of the curvature of the onboard rubber. At the central part it is 5 mm, at the corner 1 mm. In addition, the template repeats the angular slope of the U-118 bead rubber used to assemble billiard tables involved in Russian billiards. The angular inclination of the side tires for the corners and for the central ones is 29 degrees 45 minutes. The angle between the parts of the corner pocket template is 90 degrees. The template with the 70/80 plate has a size of 71 mm in the part that is installed in the target of the corner pocket, and 80.5 mm in the central part, respectively.

To control the symmetry of the central pocket, a window (4) was made, which allows you to see how much the symmetry of the central pocket differs from the ideal one (Fig. 6).

The template in each of its parts has a recess under the arm, which allows the table assembler to easily take it when installing the boards or when controlling the corner and central pockets during tournament competitions.
