Description

The golf club handle of composite
(1) technical field
The utility model relates to a kind of golf club handle.
(2) background technology
Be the outside drawing of golf clubs in the past as shown in Figure 1, golf clubs 1 in the past mainly comprises three parts, be respectively a bar head that contacts with golf ball body 11, a handle 12 for user's gripping, reach one in order to connect the shaft 13 of this bar head 11 and this handle 12, because handle 12 is the parts that directly contact with the user, therefore, the design of handle 12 is especially important.Golf club handle 12 in the past has various style, size and material, be available for users to select, because everyone hand size and thickness all more or less have some differences, therefore, the user should select hand size and the lucky golf club handle 12 that cooperates of thickness with oneself for use, size is for the very important influence of selecting for use of handle 12, so-called size is meant the thickness+internal diameter after handle 12 is installed in club, whether the thickness of handle 12 appropriately will influence the user when gripping and the sensation in when swinging, when the thickness of handle 12 is not enough or blocked up, the user is difficult for gripping, and then influences smooth degree and the outbound form of golf ball (as Draw (HOOK) or miss (SLICE)) that swings.
As mentioned above, golf clubs 1 is by bar head 11, handle 12 and shaft 13 are formed, therefore the change on arbitrary construction weight will inevitably have influence on gross weight (the total weight of whole golf clubs 1, or claim static gross weight) and swing weight (swing weight), the meaning of aforementioned swing weight is a nose heave amount of being felt when swinging of bar, the distribution of club weight just, being that a kind of bar is nose heave heavily reaches the heavy ratio of handle with shaft, swing weight is bigger, bar head speed is faster, square stance strength is bigger, ball flies far, swing weight is differentiation with Luo Lashimike scale (lorythmic scale) more generally, with English alphabet A, B, C, D, E, F and G are distinguished into seven grades, each grade is divided into ten scales such as 0 ~ 9 grade again, the grade back of healing, then swing weight is bigger, the grade front of healing, then swing weight is littler, and for example: the swing weight of grade D0 is the swing weight less than grade D5.General male sex sportsman only uses the golf clubs 1 before grade D0 ~ D5, grade D5 later on normally male sex's professional class using.
From the above, the weight change of club 1 three parts (bar head 11, shaft 13 and handle 12) can have influence on static gross weight and swing weight.The manufacturing commercial city of most of golf clubs 1 increases swing weight by weight that reduces shaft 13 or the weight that increases bar head 11; The manufacturer of a few exceptions reaches the purpose that increases swing weight with the size that thin rubber material changes handle 12, yet so but can make handle 12 lose suitable size; Handle 12 whenever increases, when subtracting 4 g, the grade that makes swing weight is subtracted, increases lorythmic scale1 scale, when the grade of swing weight only increases, subtracts 1 scale, general user is difficult for feeling, substantially, when the grade of swing weight increased, subtracts 3 scales, the user just can feel the variation of weight.
Because golf swing is the extremely strong a kind of motion of instantaneous burst power, at square stance, the vibrations that impact produced of club and ball often hurt arm muscle because of hand-tight handle passes to sportsman's hand, so the shock absorption of handle is improved also very important.
Golf club handle 12 in the past is to adopt monolithic rubber or synthetic plastic is molded forms, because of it has surface anti-skidding, tough and tensile and have advantages such as elasticity, after golf clubs 1 often uses a period of time, the surface of handle 12 can wearing and tearing or hardening and become more sliding, influence the degree of accuracy that the user swings, therefore need to change; When changing handle 12, two kinds of selections can be arranged, just embedded type handle or coil type handle, explanation as back respectively:
1. changing the outfit about the embedded type handle--at first remove handle originally, shaft 13 ends are exposed, then paste double faced adhesive tape in coating on the position of script handle, assistance that then need be by some instruments and chemical solvent could be incited somebody to action roughly and the identical hollow embedded type handle of shaft 13 external diameters, wears up from the end of shaft 13; Because the embedded type handle is high and very time-consuming at the degree of difficulty of installing, can't finish by general golf player, so the golf player needs its club 1 is transferred to golf shop a couple of days of specialty so that changing the outfit of handle 12.
2. changing the outfit about the coil type handle--at first remove handle originally, shaft 13 ends are exposed, then coil type handle 2 could be installed on the position of script handle, as shown in Figure 2, the elongate resilient band 21 that one inner face is adhesive with double faced adhesive tape is wound in outside the shaft 13 to the direction at bar head 11 places gradually from the end of shaft 13, elastic webbing 21 edge strips 210 on the volume of back must be close proximity to elastic webbing 21 edge strips 210 on the last volume during coiling, after treating that elastic webbing 21 coilings are finished, put a retainer ring 22 and an elastomeric cap (cap) 23 again in the two ends of elastic webbing 21 respectively, so promptly finish the replacing of coil type handle 2; Compared to the degree of difficulty of the embedded type handle that changes the outfit, the coil type handle is easier to be installed voluntarily by general golf player, yet the coil type handle that changes the outfit still has the following place that should note and shortcoming:
(1) when coiling elastic webbing 21, must focus one's attention on very much, otherwise promptly can't reel smooth-goingly, and accidentally just make adjacent winding produce the gap easily.
(2) because retainer ring 22 and elastomeric cap 23 assemble in addition, in use for some time, be easy to come off, particularly the part of elastomeric cap 23 is all the more so.
Patent about the coil type handle is quite a lot of, and its major requirement all is that the user can be installed easily, yet still has some shortcomings, enumerates the explanation back:
(1) U.S. the 2nd of Michael J. Prey De Jiasite (Michael J.Prendergast), 721, No. 741 patents, it discloses the upper shield that winding part and that a golf club handle has a spirality breach forms in the winding end, the terminal correspondence of upper shield end and shaft is formed with trip (key) and the slot (slot) that cooperatively interacts, and makes upper shield be positioned the shaft end; Its shortcoming is: when mounted, at first must make a slot at the shaft end by instrument, cause operational difficulty, then finish the coiling of winding part on shaft, just upper shield is positioned the shaft end then, for general golf player high degree of difficulty is arranged and be difficult to carry out, being easy to install of this and this case institute demand deviated from fully.
(2) U.S. the 4th of Gai Se (Gaiser), 174, No. 109 patents, it discloses a golf holding rod is to be made by a belt with open cellular type (open-celled) foam structure, and be wound in shaft spirally, the two has an open edge in adjacent cover part, then has adhesion at the back side of open edge; Its shortcoming is: the employed winding material of this case is open cellular type foam structure, makes very soft of winding, so that square stance can't provide firm support, and makes and installing unusual difficulty and time-consuming.
(3) patents such as the U.S. the 5th, 816,933 and 5,813,921 of yellow (Huang) disclose and finish the various compound golf club handle that winding that unification open pores inner textile layer (for example felt) and the synthetic outer cortex of a sealed porosity polyamine fat constituted forms.Basically, this golf club handle is formed by being coated on the outer winding (5,816,933 patents as described above) of shaft spirally, then putting a upper shield (cap) separably in the shaft end throws off to prevent belt, in other words, the handle of this type needs two steps when mounted at least, and forms a strength tolerances than weakness between upper shield and winding, because upper shield is to be installed on shaft in addition, but not integrally formed with winding, in use for some time, upper shield gets loose easily; In addition, this winding is too thin, flat and too soft, its thickness is difficult to surpass 2.5mm, so that be only applicable to the shaft (0.790 " ~ 0.865 ") of large-size, because the winding internal layer is the woollen layer (felt layer) of perforate fabric, tough and tensile inadequately, can't be as adopted rubber or hot plastic rubber to provide the square stance that swings enough supports in the past.This golf club handle also can be by being wound in winding on one sleeve pipe, and then sleeve pipe is coated on shaft outer (as described above 5,813,921 patents, so that handle thickness increases) form, like this, though can avoid the shortcoming of the aforesaid U.S. Patent of Huang, yet when this handle is installed in shaft, be subjected to the restriction of winding, so that be difficult for sleeve pipe is strutted, cause the difficulty of installing.
Therefore, the selection of handle must be considered following factor especially with installation, for example suitable handle size, weight (this can influence swing weight and speed), skid resistance, shock absorption, be easy to install or the like, more than all personal like and the demand with the golf player is relevant.
