Description

The utility model relates to sports equipment and is designed to move balls on the pool table by hitting them with a thin part of the cue.

The following technical solutions are known from the prior art.

Known cue with a sheath of carbon fiber and with a polyurethane foam core (UK patent No. 21995505, 07/13/1988). The cue includes an impact tip, shaft, carbon fiber sheath, filled with a polyurethane foam core in its intermediate part, with space at the front end, the front end of the carbon fiber connector, glued to the impact tip and rod at the rear end of the connector for insertion into the front end parts of the shell and core contact. The butt of the cue is closed with a plastic sleeve and a rubber tip.

Known billiard cue (RF patent No. 123331, 12/27/2012) whose body includes a drummer, a middle part, consisting of a set of reciprocal reciprocal shapes and interconnected inserts, and a turner, characterized in that each insert of the middle part is made in the form of a hollow details having the shape of a paraboloid directed by the apex towards the drummer, while all the inserts are located coaxially.

The closest analogue of the claimed utility model is a cue, comprising a shell of carbon fiber, forming a hollow body and a core made of solid wood; the shaft and turnstile cue are connected by means of a threaded connection (Chinese patent No. 102764500, 11/7/2012).

A disadvantage of the known solution is the deterioration of the cue sliding on the arm due to the continuous coating of the cue with carbon fiber, while the black color of the cue interferes with aiming around its ball. In addition, the continuous installation of carbon fiber does not provide the optimal wave of oscillation that occurs when a product collides with a billiard ball. These shortcomings do not provide good gaming characteristics cue.

The technical result of the proposed utility model is to improve the gaming characteristics of the product by achieving the necessary elasticity and density of the cue.

The claimed technical result is achieved due to the design of the cue for Russian billiards, including shaft made of wood with a sticker on the end and the turnstile, sequentially connected to each other flush with a threaded connection and installed along the longitudinal axis, while in the shaft part and in the turnstile part in the region their connections to each other are cut out grooves with a depth of 1 ÷ 5 mm, a carbon fiber with epoxy resin is pressed onto each groove.

As a result of this treatment of the flow of cues with carbon fiber with a synthetic thermosetting resin with crimping, a homogeneous layer of carbon fiber is obtained, which is also called carbon fiber or high modulus graphite.

Unlike the shell completely made of high-modulus graphite, the proposed technical solution provides an increase in the elasticity and density of the cue due to the fact that the installation location of carbon fiber is selected so that when it hits a billiard ball, an optimal product oscillation wave occurs.

The cue stick is strengthened with threads of natural or synthetic origin of various colors by wrapping them on the handle and fixing with high strength glue.

For better grip with the hand, inserts made of artificial or jewelry rubber are inserted into the base of the handle.

Next, the solution is illustrated by reference to the figure, which shows a General view of the cue for playing billiards.

The claimed cue includes serially connected to each other flush and installed along the longitudinal axis of the shaft (1) 800–850 mm long, the turner (2) 750–900 mm long. The basis of the components is made of natural wood of hornbeam.

The shaft (1) and the turnstile (2) are connected by means of a threaded connection (4). The handle (3) is strengthened with threads of natural or synthetic origin of various colors by winding them and fixing them with high strength adhesive. For better grip with the hand, the base of the handle (3) is made of artificial or jewelry rubber inserts by cutting at the base of the turnstile, pre-treated with threads with glue, grooves in several places on the handle, and gluing rubber mates into them. Rubber can be used synthetic or jewelry.

To achieve the necessary elasticity and density of the product, which are necessary to improve the gaming characteristics of the cue, the product is reinforced with carbon fiber (another name is carbon fiber roving).

To do this, a groove (5) is made in the wood (recess) to a depth of 1-5 mm, depending on the task (more dense and resilient cue or less resilient and dense cue), the length of the groove in the shaft portion is 300 ÷ 450 mm, the length of the groove in parts of the turnstile 300 ÷ 450 mm. Next, carbon fiber is laid in this groove by winding it with epoxy resin and crimping it using heat-shrink film (tube) or using vacuum bags. Before winding, carbon fiber is impregnated with epoxy resin. The result is a uniform layer of carbon fiber, which is also called carbon fiber or high modulus graphite. The groove in the part of the turnstile and in the part of the shaft is made in such a way that a section with carbon fiber is formed in the central part of the cue in the area of the connection of the shaft and the turnstile. The location of the groove is selected by calculations taking into account the properties of the materials for the formation of an optimal wave of vibrations (6) in such a way that at the beginning and at the end of the section with carbon upon impact of the cue ball with the ball, the vibration amplitude (6) of the cue was close to zero.

For winding can be used carbon fiber (roving) of various grades and properties for example.
