Abstract

The present invention relates to a billiard ball rod which comprises a wooden shaft rod, wherein the rod body is at least provided with a hollow section which can extend along the shaft center, a solid section and an inner rod, wherein the hollow section is provided with a preset inner diameter and comprises a shaft hole with a preset hole diameter; the inner rod is made from material with the rigidity higher than wood, the length and the outer diameter of the inner rod correspond to the shaft hole, and the inner hole is tightly arranged in the shaft hole. Thus, the solid part of the ball rod can exert the advantages of wooden materials; the inner rod with high rigidity not only can prevent a wooden rod body from bending and deforming because of being wetted, but also can improve the stability of ball control of the ball rod because the wooden rod body is replaced by the inner rod.

Description

The billiard stick of improvement

The present invention is relevant with billiard stick, particularly about a kind of billiard stick with improvement axostylus axostyle (Shaft).

Wood materials is owing to have specific elasticity and toughness, be fit to very much be used for making billiard stick, precisely because still having some shortcomings still can't overcome so far, for example wooden club makes moist and flexural deformation easily, moreover then be that the timber that is used for making shaft is to take from natural timber, and same natural timber can form different fibre structures because of the difference that becomes long priority and environment, therefore after it makes club, the elasticity of each part shaft of this club and rigidity can produce difference with the difference of work fibre structure, and this kind situation can cause considerable influence for the ball-handling of club.

Main purpose of the present invention is promptly providing a kind of billiard stick of improvement, and it can be possessed the advantage of wooden shaft but can not be subjected to the influence of environment and flexural deformation, and in other words, it can make wooden club keep its glacing flatness for a long time.

Another object of the present invention is then providing a kind of billiard stick of improvement, and it can improve the stability of ball-handling under the situation that keeps wooden shaft advantage.

For reaching aforesaid purpose, a kind of billiard stick provided by the present invention includes a wooden axostylus axostyle, and its shaft has a hollow section of extending along its axis and one solid section at least, and this hollow section includes the axis hole of a tool preset aperture; And bar in, to make for high material so that rigidity is more wooden, length and external diameter are closely to be placed in this axis hole corresponding to this axis hole; Thus, the solid part of this club can be brought into play the advantage of wood materials, and the bigger interior bar of this rigidity can prevent wooden stick's damp flexural deformation of experiencing on the one hand, then wooden shaft is replaced by bar in this because of having partly on the other hand, and should can optionally select suitable material by interior leverage, for example full the genus or fiber reinforcement plastic, the institutional framework of these materials be owing to can make it be consistent on making, thereby can improve the ball-handling stability of this club.

The present invention is described further below to enumerate a preferred embodiment and conjunction with figs., wherein:

Fig. 1 is the stereogram of a preferred embodiment of the present invention;

Fig. 2 is a preferred embodiment of the present invention cutaway view on the 2-2 direction in Fig. 1;

Fig. 3 is the part exploded view of a preferred embodiment of the present invention.

See also each diagram, a preferred embodiment of billiard stick provided by the present invention is shown in figure number 10, and it has an axostylus axostyle (Shaft) 12 and a pressure pin (Butt) 14, one base of a fruit heads 16 and a pad 18.

An axostylus axostyle 12 and a pressure pin 14 are to be screwed onto together by a male and female spiro connecting piece 20,22.This base of a fruit head 16 is the front ends that are fixed in axostylus axostyle 12, and this pad 18 is the bottoms that are fixed in pressure pin 14.

Axostylus axostyle 12 is that for example maple (Maple) is made by natural wood materials, is 736.62mm (29 inches) in its total length of present embodiment, is pushing and drawing shape (Taper), and is divided into two joints.Wherein the length of first segment body portion 24 is about 508mm (20 inches), and it has a front end 26, and external diameter is about 13.2mm (0.52 inch), 28, one first solid sections 30 of rear ends, and one first hollow section 32.Hollow section 32 has an axis hole 34, and its aperture is about 7.1mm (0.28 inch), and length is about 279.4mm (11 inches), and has an opening 36 that is positioned on the end face of rear end.

The second joint body portion 38 is connected in first segment body portion 24 rear ends, and its connected mode has multiple for example sticking work or is spirally connected, because its non-target of the present invention is so will not describe in detail.The length of the second joint body portion 38 is about 228.6mm (9 inches), and it has a front end 40, and external diameter is about 21.3mm (0.84 inch), a rear end 42, one second hollow section 44, and one second solid section 48.Hollow section 44 has an axis hole 46 equally, and its aperture is about 7.1mm (0.28 inch), and length is about 101.6mm (4 inches) (or short in 50.8mm (2 inches)), and has an opening 50 that is positioned on front end 40 end faces.

Furtherly, the present invention makes axostylus axostyle 12 front and back ends all have one solid section, and after its two joints body portion combination, form an aperture and be at least 5mm (0.2 inch), length is at least the slotted hole of 254mm (10 inches), in the aperture of this slotted hole of present embodiment is 7.1mm (0.28 inch), and length is 381mm (15 inches).What must one carry is that above each numerical value only is a preferred embodiment of the present invention, its visual actual needs and multiple selection is arranged.

One hollow interior bar 60, it is to make for high material so that rigidity is more wooden, for example metal or fiber reinforcement plastic, its length and external diameter are corresponding to this axis hole respectively, and its two ends penetrate each

hollow section

32,44 and closely are placed in this slotted hole from each opening 36,50 respectively.

By as can be known aforementioned, axostylus axostyle 12 is owing to possess the wooden solid part that is positioned at front and back ends, so it is at square stance, still can bring into play the certain elasticity and the toughness of wooden club.In addition, the wooden shaft of the part of axostylus axostyle 12 is then replaced by the bigger interior bar 60 of rigidity, bar can prevent wooden stick's damp flexural deformation of experiencing on the one hand in this, then select suitable material on the other hand because of its visual actual needs, for example metal or fiber reinforcement plastic, and the institutional framework of these materials can make it be consistent according to present manufacturing technology, and therefore, the shortcoming that existing wooden club is subjected to fibre structure own to influence its ball-handling stability minimizes when draping over one's shoulders.
