Description

[0001] The utility model relates to the field of sports table games and can be used in the design of tables for playing table tennis.

[0002] A table tennis table is known from the prior art, comprising a playing surface in the form of a tabletop mounted on posts (RU 129829 U1, 10.07.2013 / D1 / ). A disadvantage of the prior art technical solution D1 is that it can only be used during daylight hours and lacks protection from precipitation and other environmental factors.

[0003] The aforementioned deficiencies have been addressed in a well-known table (RU 107908 U1, 10.09.2011 / D2 / ), which has a glass tabletop with LED under-illumination linked to a control unit for the backlight parameters. However, the D2 table is not intended for use as a table tennis table.

[0004] Also known from the prior art is a tennis table (SN 703726 A2, 21.10.2025 / D3 / ), adopted as the closest analogue, comprising a tabletop made of multilayer tempered glass, mounted on movable supports, designed with the possibility of changing the height of the table, and white LED strips built into the tabletop, designed with the possibility of regulating the brightness of the table lighting.

[0005] At the same time, the disadvantages of the D3 table include the insufficiently clear delineation of the boundaries of the table's playing area for use by players in low-light conditions, for example, at night, as well as for use by players with impaired vision.

[0006] The technical problem that the utility model is aimed at solving is the creation of a table tennis table that allows players with impaired vision to use it in conditions of insufficient lighting of the surrounding space.

[0007] The technical result achieved by the proposed utility model is an increase in the brightness of the illumination of the boundaries of the playing area of ​​the tennis table in conditions of insufficient lighting.

[0008] The said technical result is achieved in that in a tennis table comprising a tabletop made of multilayer tempered glass mounted on movable supports configured to change the height of the table, and white LED strips built into the tabletop configured to regulate the brightness of the table lighting, the tabletop is made with an upper matte, middle and lower transparent glass, wherein the middle glass consists of two identical parts installed to form a channel located in the middle of the tabletop and channels located along the perimeter of the tabletop between the edges of the upper and lower glasses protruding along the edges of the middle glass, wherein the said LED strips are placed in a U-shaped metal radiator mounted in the channel located in the middle and in two parallel U-shaped metal radiators installed in channels located along the perimeter of the tabletop,wherein on the lower side of the lower glass of the tabletop there is installed an LED grid connected to a corresponding power supply unit, which is closed from below by a metal sheet attached to the tabletop, wherein the LED strips installed in one of the channels located along the perimeter are connected through a corresponding power supply unit and a photo relay to a light sensor installed on one of the movable supports of the table, and the LED strips installed in the second of the channels located along the perimeter of the tabletop, and the LED strips installed in the channel located in the middle of the tabletop are connected through a manual brightness controller to the corresponding power supply unit.

[0009] The mentioned power supplies, regulator and photo relay are located in a box fixed on one of the movable supports of the table.

[0010] At the same time, the mentioned channels in the area around the metal radiators with LED strips and the gaps between the metal sheet and the lower glass are filled with transparent silicone.

[0011] The utility model is illustrated by drawings showing:

[0012] Fig. 1 - top view of the table top with a cross section;

[0013] Fig. 2 - view of the table top from the bottom with a cross section;

[0014] Fig. 3 - connection diagram of LED strips and mesh.

[0015] The tennis table comprises a tabletop made of multilayer tempered glass mounted on movable supports, for example, with wheels configured to change the height of the table by means of mechanisms known from the prior art (not shown in the drawings), for example, using table support posts containing, among other things, telescopic posts with a cavity design, as well as an adjustment rod and an eccentric wheel located at the lower end of the adjustment rod, while universal wheels are located on the lower end surfaces of the support posts that can drive the table tennis table (CN 107376272 A, A47B 25 / 00, 24.11.2017) or using table support posts containing pushers with wheels attached to them from below that have the ability to move up and down due to sliders driven in guides by means of an electric drive (CN 107136759 A, A47B 13 / 02, 09 / 08 / 2017).

[0016] The tabletop is made of multiple layers with top glass 1, middle glass 2 and bottom glass 3, which are connected, for example, glued, to each other.

[0017] The top glass (1) is frosted glass, providing uniform illumination across the tabletop and sharper definition of the playing field edges by equalizing the illumination from the multiple LED grids and strips embedded in the tabletop. The middle glass (2) and bottom glass (3) are transparent. The top and middle glass (1 and 2) can be made, for example, 6 mm thick, while the bottom glass (3) can be made 4 mm thick.

[0018] The middle glass 2 consists of two identical parts installed to form a channel 4 between them, located in the middle of the tabletop, and channels 5 located along the perimeter of the tabletop between the edges of the upper and lower glass 1 and 3 protruding along the edges of the middle glass 2.

[0019] In channels 4 and 5, U-shaped metal radiators 6 are installed with LED strips 7 placed in them, and in the channels located along the perimeter of the tabletop, two parallel radiators 6 are installed, and in the channel located in the middle of the tabletop, one radiator 6 is installed.

[0020] The walls of these heat sinks, such as aluminum ones, create a barrier to the divergence of LED beams, which are contained within a well after the areas around the heat sinks containing LED strips are filled with transparent silicone. This enhances the brightness of the illumination of the playing field perimeter by creating a unidirectional effect of these beams. This effect is also enhanced by the simultaneous installation of two parallel heat sinks, making it easier for players to use the table tennis table in low-light conditions. Furthermore, the heat sinks provide additional heat dissipation from the LED strips 7 located within them, thereby maintaining their temperature within the required limits under various all-weather operating conditions.

[0021] An LED grid 8 is attached (e.g., glued) to the underside of the lower glass 3 of the tabletop. The tabletop is covered from below with a metal sheet 9 attached to the lower glass 3, for example, by means of metal bars 10 glued thereto. The sheet 9 is fastened by any available means, for example, by means of metal brackets 11 to the movable supports of the table (not shown in the drawing). The gaps between the metal sheet 9 and the lower glass 3, as well as the areas around the radiators with LED strips, can be filled with transparent silicone to prevent condensation from forming in these areas, which affects the operation of electrical elements and circuits. Moreover, the transparent silicone helps to maintain the brightness of the illumination of the perimeter of the table without interfering with the passage of the LED beams.

[0022] The LED grid 8, attached to the lower glass 3, is electrically connected through a manual brightness controller 18 (dimmer) to the corresponding power supply unit 12. The LED strips 7, installed in one of the channels located along the perimeter of the tabletop, are connected through a corresponding power supply unit 13 and a photo relay 14 to a light sensor 15 installed on one of the movable supports of the table. And the LED strips 7, installed in the second of the channels located along the perimeter of the tabletop, and the LED strips 7, installed in the channel located in the middle of the tabletop, are connected through a manual brightness controller 16 (dimmer) to the corresponding power supply unit 17.

[0023] In this case, power supply units 12, 13 and 17, lighting brightness regulators 16, 18 and photo relay 14, to ensure reliable operation in any weather conditions, are located in a box fixed on one of the movable table supports (not shown in the drawing), which has the ability to be connected, for example, to a 220 V network.

[0024] For use, the table is adjusted to the desired height using its movable supports. To enable play by visually impaired players and / or in low-light conditions, power supplies 12, 13, and 17 are turned on. LED grid 8 provides uniform illumination of the entire tabletop, while LED strips 7, located around the perimeter and in the center of the tabletop, provide appropriate markings of the playing field in the form of light strips, the brightness of which can be adjusted, if necessary, using dimmer 16.

[0025] In the event of a significant decrease in the illumination of the space surrounding the table, a signal from the illumination sensor 15 is received via the photo relay 14 and the power supply unit 13, turning on the second line of LED strips 7 located along the perimeter of the tabletop, automatically increasing the brightness of the glow of the boundaries of the playing field.

[0026] Thus, the combination of all the essential features of the utility model contained in the independent claim ensures the achievement of the above-mentioned technical result, allows for the use of the tennis table by players in any weather conditions, in low light conditions, including in the evening, and in particular by players with impaired vision.
