Detailed description of the invention

Fig. 1 shows golf ball bar body 10, and its one end is attached to head (not shown), And its other end is attached to golf grip 12.The building material of golf grip 12 can be Arbitrarily moulding material, the most naturally occurring or synthetic rubber or have as rubber or similar Elasticity and the polymer of shock absorbing characteristics.Such material is generally composited with implant, with Reduce rubber costly or the volume of polymer.The present invention considers also weight implant to be attached to In the building material of handle 12, to increase the weight of handle.It is preferably to be existed by density Between 1.1g/cc to 1.8g/cc, preferably the complex between 1.4g/cc to 1.8g/cc by Handle molding.We have found that the complex applying barium sulfate and white carbon implant in rubber will Obtain the ideal density between 1.4g/cc to 1.8g/cc.But, realize the present invention's in expectation In the case of compensating function, the implant of particle form is preferably randomly provided, and not at handle On cause weight to concentrate.It is also preferred that the outer surface at the period handle that swings will not be from height Skidding off in the hands of golf ball person, therefore the outer surface of handle is sometimes provided with feel and more preferably and assists Textured surface 13(Fig. 5, Fig. 7 that linksman grips).

When being assemblied on golf ball bar body 10, golf grip 12 is around hollow bar The periphery of body 10 extends, and golf grip covers the end 14 of shaft 10, in Fig. 1 16 shown in.Although we have been illustrated with the metal shaft of hollow, but golf clubs is led Material that the technical staff in territory has the ability to be used according to shaft completely (such as timber, metal, Such as composites such as graphite-filled polymer) characteristic hollow or solid shaft are provided.

In one embodiment of the invention, counterweight 18 is disposed in a mold, in order at least Partly or the most all by the building material bag of the golf grip 12 shown in Fig. 1 Envelope.This counterweight can with use cylindrical tube form, as it is shown in figure 1, or preferably, can With by two half-unit 20,21(Fig. 3) formed, in order to weight placement in a mold and is pacified Put the final position in molding handle.The thickness in cylindrical shape half portion 20 can be 0.039 English Very little, and length can be 2³/₄Inch.These values are for the counterweight formed by mild steel. When metal finer and close (the such as tungsten) used, these thickness and length value are bigger by causing Bulk density.If one or more embodiments described herein are applied in combination, by height The weight of your husband's handle increases to 92+/-3 gram and falls within the scope of the present invention, preferably weight At least 95 grams.The internal diameter of counterweight should be greater than the external diameter of golf ball bar body 10, so joins Weigh (or the inside in half portion 20,21 being assembled together) on the inwall of 18 can have by The coating that grip structure material is made, as 17 in figure 1.This makes handle 12 more hold Easily it is installed on shaft 10, without making the surface of counterweight 18 directly contact shaft 10, and handle 12 is played buffering.The quality that can change counterweight 18 compensates by Gao Er Husband's club head (not shown) and the size of golf ball bar body 10 and weight are incorporated into height Variation in the balance of golf club.

In other embodiments, counterweight 18(or half portion 20,21) in can be provided with and wear Hole, to allow the building material of handle 12 through counterweight.These perforation can be any shape Single or the multiple through hole of (such as, circle, elongated shape, tetragon, hexagon etc.), But it is preferably circular or tetragon.In some aspects, the quantity of this some holes is many, so that Start to be rendered as grid or trellis pattern in counterweight 18, such that it is able to arrange or be wound around multilamellar Weight material is to form final counterweight.Bored a hole by offer or grid/trellis pattern structure, It is able to ensure that building material is in close contact with counterweight 18.It is of course also possible to be applied in combination bonding Agent, surface roughness and other assist in ensuring that the building material of counterweight and handle 12 is closely tied The method closed.

Counterweight described herein is preferably formed by metal, and suitably metal include ferrum and Alloy (including steel) and other compact metal.Although the density of lead and gold makes them also may be used To become feasible candidate material, but the environmental treatment of the cost of gold and lead reduces conduct The probability of suitable metal.We the most preferentially select tungsten and alloy thereof to join as the band of the present invention The material of the golf grip of weight selects.Tungsten has high density, reaches 17 grams every cubic centimetre. When for embodiment discussed herein, the golf grip of the band counterweight of the present invention can compare Conventional golf grip weighs 40% to 90%.This additional counterweight helps compensate for being provided with The golf clubs of counterweight.Although we are it has been mentioned that tungsten individually or acts as with its alloy one For preferred metal, but the equivalent counterweight using the metal of not tungstenic to make also falls into the present invention Within the scope of.In this case, the volume of the metal of tungstenic can be not bigger so that close The equivalent weight of tungsten or the weight of tungsten alloy.Such metal includes that copper and alloy thereof are (such as yellow Copper and bronze), ferrum and alloy (including different grades of steel), aluminum and alloy, pottery And ceramic metal.

In alternative embodiments, counterweight can be positioned in the least significant end of golf clubs, So during brandishing golf clubs, per unit weight provides maximally effective compensation.At Fig. 5 In shown embodiment, counterweight 30 is positioned in the least significant end of handle 12, and this counterweight Upper surface is the most visible.Counterweight 30 is made the end of handle to be completely covered so that this end Invisible also fall into the scope of the present invention within.Covering can be molding compound itself, or Person is placed in the discrete item in counterweight 30, and this discrete item is connected to handle complex or is held Complex is caught.This counterweight can also be made up of the material identical with material discussed here, But preferably separately made by tungsten, or it is made up of tungsten and alloy thereof.The tungsten of one cubic centimetre can The counterweight of 17 grams is formed with the least significant end at handle 12.Counterweight 30 can take many forms, Including arranging perforation 32(Fig. 9 that grip material 33 can flow through), and arrange and can prolong Put in the protuberance 39 in the material of handle 12.It is not only perforation 32 and protuberance 39 guarantees Counterweight 30 and handle 12 combine, and as shown in Figure 6, it is also possible to shape in counterweight 30 Become flange 34, and flange 34 is caught by handle 12, such as the partial section view institute in Fig. 6 Show.As shown in Figure 6, the boundary portion 35 of grip material is in the end of shaft 10 and counterweight 30 Between extend.

Fig. 5 and Fig. 6 illustrates the longitudinal axis L of handle 12.Fig. 9 illustrates the longitudinal axis of counterweight 30 Line L1.Counterweight 30 has disk-shaped portion 31 and protuberance 39.It is embedded into handle 12 The longitudinal axis L 1 of the counterweight 30 in end is directed at the longitudinal axis L of the handle 12 shown in Fig. 5 And overlap.Counterweight 30 crosses longitudinal axis L thus around the longitudinal axis L of handle 12.

Figure 12 illustrates the alternative disc counterweight 130 of the handle 112 for Figure 13, counterweight 130 have longitudinal axis L 2.

The alternate embodiments of the counterweight 30 shown in Fig. 5 shows in fig. 12.Figure 12 illustrates The counterweight 130 of another embodiment, this counterweight 130 has multiple perforation or hole.These perforation 131, the existence of 132,133,134 makes the moulding material molding at handle of handle Journey can pass counterweight 130, counterweight 130 to be firmly held in the desired locations of handle. Perforation 131,132,133 and 134 can have a non-circular configuration, or can with cross section in Circular.Although we have been illustrated with four perforation, but perforation can be more or less than four, For example, two, three, five or more.Preferably bore a hole around the axis of counterweight 130 Arrange equably, to avoid bringing beyond thought change to distribution of weight.But, wittingly Within the counterweight of introducing non-uniform mass also falls into the scope of the present invention.One or more wear Hole can comprise indicator, such as groove 144(Figure 12), to assist counterweight 130 to be oriented in mould Specific location in tool.Alternately, or in addition to groove 144, central hole itself (in Figure 15, central hole 160 is square can also various shape；In Figure 16, in Heart perforation 170 is triangle), such that it is able to be used as counterweight relative to handle moulding material And/or the orientation element relative to the handle position on shaft.This labelling or design by with Being particularly desired in when appearing in part in counterweight, and expect these labellings or pattern Orientation.It is also likely to be when the non-uniform mass of counterweight useful, and expects to make inequality Even quality is orientated in particular directions relative to handle and/or shaft.

Although we have been illustrated with several shape, but it should be expressly understood that arrive, it is possible to use Can act as being orientated any shape of element.The limiting examples of this kind of shape includes such as square The tetragons such as shape, trapezoidal and rhombus, pentagon, hexagon, heptagon (hexagon), eight Limit shape etc., also includes the part-circular in flat portion or has the circle of extension slot, such as key Keyhole shape.In the forming process of the plastic complex of handle, mandrel and orientation element can be made Coordinate to be orientated counterweight relative to handle.

As shown in the partial section view of Figure 13, the moulding material of handle extend through perforation with Counterweight 130 is firmly held relative to handle and positions.In this counterweight, also comprise center wear Hole or steam vent 140, steam vent can extend through moulding material 141 and will hold with auxiliary On the shaft being arranged on golf clubs.Steam vent 140 and steam vent 141 match and will appoint The air what is detained discharges handle.This is particularly desired in the case where there: when cutting of shaft When face is solid, or shaft has been loaded into head, or air is stagnant when installing handle Stay in any case, either in the case of coming of new golf clubs or at replacement ball It is all desired in the case of existing handle on bar.

As shown in the partial section view of Figure 13 and the perspective view of Figure 14, showing of counterweight 130 The outer surface 136 exposed is significantly less than the outer surface shown in the embodiment of Fig. 5.This is owing to joining Weigh the 130 step characteristics having compared with counterweight 30.This makes more plastic complex It is positioned at the end (contrary with head) of handle and position can be reserved to the setting of labelling, than Name, golf clubs maker or the most specific country club such as handle maker Or tissue.

But, as it has been described above, counterweight 30 or 130 can be by plastic complex or peace The inserts put in counterweight is completely covered, to such an extent as to so counterweight is the most invisible.

Labelling 150 can also be arranged on the plastic complex of handle itself or it In, as shown in figure 14.Labelling 150 can be the name of handle maker, trade mark, design, The name of golf clubs maker, etc..

Additionally, the outer surface of handle can be provided with uniqueness or ornamental mark, as Shown in Figure 14 151,152.It addition, the mark of these uniquenesses is capable of functional Purpose, it is, for example possible to use handle is being installed to Gao Er by arrow 153 or other indicator Alignment handle is assisted time on the shaft of husband's club.As it is shown in fig. 7, it is aobvious in the lower end of handle 13 Showing the second mark, i.e. arrow, this is useful for handle setter, second mark with Arrow 153 combination guarantees that handle 13 does not reverse when being installed on shaft 10.Alternative Ground, or except mark 153, in addition to 154, with mark 153,154 be separated by 180 degree also Additional arrow or indicator (not shown) can be there is, assist handle 13 at shaft It is directed on 10.When acting purely as decoration, mark does not possess functional purpose.

While it is true, in each embodiment in these embodiments, be preferably in one's hands Least significant end at or neighbouring employing counterweight, to bring significant compensation benefit.Counterweight also may be used Think that the labellings such as possessory initial, club logo such as provide position, such as Figure 11 institute Show.But, compared with conventional stamp cap (monogramming cap), counterweight 30(or Person 130) weigh 850% than this stamp cap.

When counterweight is made up of more unsound metal materials such as such as aluminum or its alloys, may It is necessary to increase to a certain degree by the quality of this kind of lighter material so that gross mass will not occupy Space between end and the end of handle of shaft.In this case, it is mounted when handle Time on shaft, counterweight 30(or 130) space that extends to be surrounded by shaft can be forced. In such embodiments, as shown in figure 17, the afterbody of counterweight will extend to the end of shaft In end.Afterbody can be naked metal, or can be become by the other parts all-in-one-piece with handle Type complex covers.But, in any embodiment, it is important that either afterbody is naked Metal, or the molding compound covering afterbody is all not exposed to the inner surface of shaft, because this It is introduced into being brought by club batting the less desirable vibrations of shaft, then vibrations is transferred directly to The counterweight of handle.Therefore, always it is expected between counterweight and shaft leave space.

Although having disclosed several embodiments of the present invention, but these embodiments should having been recognized For being only exemplary rather than restrictive, because for those skilled in the art It is readily apparent that by reading these disclosure contents, can be in the spirit without departing from the present invention With make various modification in the case of scope.
