CN2352222Y - Bent-proof cues - Google Patents

Abstract

The utility model relates to a bend-proof billiard ball rod which comprises a rod body with a long shaft, wherein the rod body is provided with a wood core part and a fiber reinforced plastic surface layer which is covered at the outer side of the core part, the surface layer is formed by overlapping and winding a plurality of fiber looms soaked with resin, and the whole thickness of the surface layer conforms to the range of 0.3 mm to 3 mm. Thus, the surface layer can not lose the bend-proof function even if abrasion exists in the manufacture process, and the characteristic of wood material can be completely exerted.

Description

The Bent-proof billiard stick

The utility model is relevant with billiard stick, does not particularly so have the billiard stick of its meeting flexural deformation disappearance about a kind of characteristic with wood materials.

Press, wood materials is because its specific toughness and elasticity, be fit to very much be used for making billiard stick, precisely because be subjected to climatic effect flexural deformation then to be its maximum disappearance easily, in order to solve this disappearance, the U.S. the 4th, 943, No. 333 the patent case provides a countermeasure, and it promptly is coated with fiber in the wooden shaft outside and mends plastic cement, can avoid the flexural deformation of billiard stick though wooden utility model case creator finds this countermeasure, but still there are some problems of work, for example, when the fiber reinforcement plastic top layer was too thin, this top layer tended to be undermined in the process of polishing japanning, prevent diastrophic effect and lose, otherwise, when the fiber reinforcement plastic top layer is too thick, then can lose the characteristic of wood materials.Further it up to now, there is no a kind of characteristic and don't the diastrophic billiard stick of meeting that can bring into play wood materials fully on the market and occurs.

Main purpose of the present utility model is promptly providing a kind of billiard stick of improvement, and it can be brought into play the characteristic of wood materials fully and don't have diastrophic disappearance person.

Another purpose of the present utility model is then providing a kind of billiard stick of improvement, and it can increase the degree of accuracy person of batting.

Edge is, for reaching aforesaid purpose, billiard stick provided by the utility model includes the shaft of a tool major axis, and this shaft has the fiber reinforcement plastic top layer that a wooden heart portion and is coated on this heart portion outside.This top layer is to form by containing the fiber weaving cloth coiling that is soaked with resin, and its gross thickness is between 0.3-3mm.By this, in processing procedure, this top layer can not prevent the bent function that becomes because of wearing and tearing lose it, more and the characteristic of wood materials fully can be brought into play.

Another feature of billiard stick that the utility model provides is, its shaft is by a footstalk, and one find a place to live in form, the front end external diameter of this footstalk is little than its rear end, this is found a place to live in is the rear end that is connected in this footstalk, this footstalk has one certainly apart from the about 10 inches bridge formation sections of locating to begin past its rear end definite length extended of its front end, and this bridge formation section has identical external diameter.By this, the bridging point with the rod square stance in the time of can making the aiming of this club maintains on the same position, and increases the degree of accuracy of batting.

Below lift a preferred embodiment now and cooperate diagram that the utility model is described further, wherein:

Fig. 1 is the stereogram of the utility model one preferred embodiment;

Fig. 2 is that the part shaft of the utility model one preferred embodiment is in the schematic diagram of its wooden heart portion outside covered fiber reinforced plastic nonwoven fabric layer;

Fig. 3 is the utility model one preferred embodiment cutaway view on the 3-3 direction in Fig. 1;

Fig. 4 is the zoomed-in view of the utility model one preferred embodiment part body of rod in Fig. 1; And

Fig. 5 is the part body of rod relevant position figure of the utility model one preferred embodiment aiming and rod square stance.

See also each diagram, a preferred embodiment of billiard stick that the utility model provides is shown in figure number 10, and its shaft is to be found a place to live in 30 by a footstalk 20 and to constitute.

It 30 is to be screwed onto together by male and female spiro connecting piece 40,42 that this footstalk 20 is found a place to live in this.

This billiard stick 10 has more a top base of a fruit 50 and is fixed in these footstalk 20 front ends 22, one rubber heelpieces 60 and is fixed in this rear end 32 of 30 of finding a place to live in.

This shaft has a wooden heart portion 14, and a fiber reinforcement plastic top layer 16.This top layer 16 is to contain the carbon-fiber cloth 161,162 that is soaked with epoxy resin by three, and 163 stacked coilings form.The thickness on this top layer 16 is about 1.45mm, and the wearing and tearing when this kind thickness can bear processing procedure on the one hand prevent the bent effect that becomes in order to bring into play it, can make wooden heart portion bring into play its properties of materials on the other hand again, according to creator's experience, this thickness minimum can be 0.3mm, and maximum can be 3mm.

The total length of this footstalk 20 is about 29 inches, the external diameter of its front end 22 is 13mm, the external diameter of rear end 24 is 21mm, extend 8 inches to locate to t ' be the section 26 of building bridge from begin toward this rear end 24 apart from this front end 22 about 10 inches t, this bridge formation section has identical external diameter for 26 whole sections, the size of this external diameter is to cooperate the external diameter of this footstalk front end and determine, but preferably between 12mm-14mm, is 13mm in its numerical value of present embodiment.Because the external diameter that this bridge formation section is 26 whole sections is identical, the bridging point X when therefore aiming at and the bridging point X ' of rod square stance are in same position, so aiming point P and striking point on the ball P ' error can not take place, in other words, can exactly ball be hit.

Claims (5)
