Description

Improved pool cue

本发明是和撞球杆有关，特别是关于一种具有改良轴杆(Shaft)的撞球杆。The present invention relates to pool cue sticks, and more particularly to a pool cue stick with an improved shaft.

按，木质材料由于具有特定的弹性及韧性，非常适合用来制造撞球杆，惟其仍存有若干缺点至今仍无法克服，例如木质球杆容易受潮而弯曲变形，再者则是用来制造杆身的木料是取之于天然木材，而同一天然木材会因成长时间的先后以及环境的不同而形成不同的纤维结构，因此当其制成球杆后，该球杆各部份杆身的弹性及刚性会随著纤维结构的不同而产生差异，此种情形对于球杆的控球性会造成相当大的影响。By the way, wooden materials are very suitable for making billiard cue sticks due to their specific elasticity and toughness, but there are still some shortcomings that cannot be overcome so far. The wood of the body is taken from natural wood, and the same natural wood will form different fiber structures due to the growth time and the environment. Therefore, when it is made into a club, the elasticity of each part of the club shaft And the stiffness will vary with the fiber structure, which will have a considerable impact on the ball control of the club.

本发明的主要目的即在提供一种改良的撞球杆，其可保有木质杆身的优点但不会受环境的影响而弯曲变形，换言之，其可使木质球杆长期保持其平直度。The main purpose of the present invention is to provide an improved billiard cue, which can maintain the advantages of the wooden shaft but will not be bent and deformed by the environment, in other words, it can keep the wooden cue straight for a long time.

本发明的另一目的则在提供一种改良的撞球杆，其可在保持木质杆身优点的情况下提高控球的稳定度。Another object of the present invention is to provide an improved billiard cue, which can improve the stability of ball control while maintaining the advantages of the wooden shaft.

缘是，为达成前述的目的，本发明所提供的一种撞球杆包含有一木质轴杆，其杆身至少具有一沿其轴线延伸的空心段以及一实心段，该空心段包含有一具预定孔径的轴孔；以及一内杆，以刚性较木质为高的材质制成，长度与外径对应于该轴孔，是紧密地容置于该轴孔内；藉此，该球杆的实心部将可发挥木质材料的优点，而该刚性度较大的内杆一方面可防止木质杆身受潮弯曲变形，另一方面则因有部份木质杆身被该内杆所取代，而该内杆系可视需要选择适当的材质，例如全属或纤维补强塑胶，此等材质的组织结构由于在制造上可使其保持一致，因而将可提高该球杆的控球稳定度。The reason is that, in order to achieve the aforementioned purpose, the billiard cue stick provided by the present invention includes a wooden shaft, the shaft of which has at least one hollow section extending along its axis and a solid section, and the hollow section contains a predetermined the shaft hole of the aperture; and an inner rod, made of a material with higher rigidity than wood, the length and outer diameter correspond to the shaft hole, and are tightly accommodated in the shaft hole; thereby, the solid body of the club The part will be able to take advantage of the advantages of wooden materials, and the inner rod with greater rigidity can prevent the wooden shaft from being bent and deformed by moisture on the one hand, and on the other hand, because part of the wooden shaft is replaced by the inner rod, the inner rod The bar system can choose appropriate materials according to needs, such as all-metal or fiber-reinforced plastics. The organizational structure of these materials can make them consistent in manufacture, thus improving the ball-controlling stability of the club.

以下兹举一较佳实施例并配合图示对本发明做进一步的说明，其中：A preferred embodiment is cited below and the present invention is further described in conjunction with the drawings, wherein:

图1为本发明一较佳实施例的立体图；Fig. 1 is a perspective view of a preferred embodiment of the present invention;

图2为本发明一较佳实施例于图1中2-2方向上的剖视图；Fig. 2 is a sectional view of a preferred embodiment of the present invention in the direction of 2-2 in Fig. 1;

图3为本发明一较佳实施例的部份分解图。Fig. 3 is a partial exploded view of a preferred embodiment of the present invention.

请参阅各图示，本发明所提供撞球杆的一较佳实施例如图号10所示，其具有一轴杆(Shaft)12及一托杆(Butt)14，一蒂头16及一托垫18。Please refer to the drawings, a preferred embodiment of the billiard cue provided by the present invention is shown in figure number 10, which has a shaft (Shaft) 12 and a butt (Butt) 14, a pedicle 16 and a holder Pad 18.

轴杆12及一托杆14是藉由一公、母螺接件20，22螺接在一起。该蒂头16是固接于轴杆12的前端，该托垫18是固接于托杆14的底端。The shaft 12 and a supporting rod 14 are screwed together by a male and a female screw joint 20 , 22 . The pedicle head 16 is fixedly connected to the front end of the shaft rod 12 , and the support pad 18 is fixedly connected to the bottom end of the supporting rod 14 .

轴杆12是由天然木质材料例如枫木(Maple)所制成，于本实施例其总长度为29英寸，呈推拔状(Taper)，且分成二节。其中第一节身部24的长度约为20英寸，其具有一前端26，外径约为0.52英寸，一后端28，一第一实心段30，以及一第一空心段32。空心段32具有一轴孔34，其孔径约为0.28英寸，长度约为11英寸，且具有一位于后端端面上的开口36。The shaft 12 is made of natural wood material such as maple, and in this embodiment, its total length is 29 inches, in the shape of a push-pull (Taper), and divided into two sections. Wherein the first shaft portion 24 is about 20 inches in length, has a front end 26 with an outer diameter of about 0.52 inches, a rear end 28 , a first solid section 30 , and a first hollow section 32 . Hollow section 32 has an axial bore 34 approximately 0.28 inches in diameter, approximately 11 inches in length, and has an opening 36 in the rear end face.

第二节身部38连接于第一节身部24后端，其连接方式有多种例如粘著或螺接，由于其非本发明的标的故不予详述。第二节身部38的长度约为9英寸，其具有一前端40，外径约为0.84英寸，一后端42，一第二空心段44，以及一第二实心段48。空心段44同样具有一轴孔46，其孔径约为0.28英寸，长度约为4英寸(或较短如2英寸)，且具有一位于前端40端面上的间口50。The second body part 38 is connected to the rear end of the first body part 24 through various connection methods such as adhesion or screw connection, which are not described in detail because they are not the object of the present invention. The second shaft portion 38 has a length of about 9 inches and has a front end 40 with an outside diameter of about 0.84 inches, a rear end 42 , a second hollow section 44 , and a second solid section 48 . Hollow section 44 also has an axial bore 46 having a diameter of about 0.28 inches and a length of about 4 inches (or shorter such as 2 inches) with an opening 50 on the end face of front end 40 .

进一步言之，本发明是使轴杆12前、后端均具有一实心段，且当其二节身部组合后形成一孔径至少为0.2英寸，长度至少为10英寸的长孔，于本实施例该长孔的孔径为0.28英寸，长度为15英寸。必须一提的是以上各数值仅是本发明的一较佳实施例而已，其可视实际需要而有多重选择。In further words, the present invention makes the front and rear ends of the shaft rod 12 all have a solid section, and when its two joints are combined, a long hole with a diameter of at least 0.2 inches and a length of at least 10 inches is formed. For example, the diameter of the long hole is 0.28 inches and the length is 15 inches. It must be mentioned that the above values are only a preferred embodiment of the present invention, and there are multiple choices depending on actual needs.

一空心内杆60，其是以刚性较木质为高的材质制成，例如金属或者纤维补强塑胶，其长度与外径是对应于各该轴孔，其两端分别自各开口36、50穿入各空心段32、44而被紧密地容置于该长孔内。A hollow inner rod 60 is made of a material with higher rigidity than wood, such as metal or fiber-reinforced plastic. into each hollow section 32, 44 and be tightly accommodated in the elongated hole.

由前述可知，轴杆12由于保有位于前、后端的木质实心部，因此其在击球时，仍会发挥木质球杆的特定弹性与韧性。另外，轴杆12的部份木质杆身则由刚性度较大的内杆60所取代，此内杆一方面可防止木质杆身受潮弯曲变形，另一方面则因其可视实际需要选择适当的材质，例如金属或纤维补强塑胶，而此等材质的组织结构依目前的制造技术可使其保持一致，因此，习用木质球杆受本身纤维结构影响其控球稳定度的缺失当可披减至最低。It can be seen from the foregoing that the shaft 12 still exhibits the specific elasticity and toughness of a wooden club when hitting a ball because it retains the wooden solid parts at the front and rear ends. In addition, part of the wooden shaft of the shaft rod 12 is replaced by a rigid inner rod 60. On the one hand, this inner rod can prevent the wooden shaft from being bent and deformed by moisture; materials, such as metal or fiber-reinforced plastic, and the organizational structure of these materials can be kept consistent according to the current manufacturing technology. minimized.
