Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • Today golf clubs are adapted to the physical conditions of a player or a player on request, not only in a static way, in which a test racket placed on the ground and the shaft length and the angle between the club head and the shaft, the so-called Lie angle be adapted to the size of the player, but also in a dynamic manner, taking into account the movement conditions when hitting a golf ball.
  • a golf club is said to be suitable if, at the moment of impact, the sole of the club head touches the ground exactly in the middle. If this is the case, the club is twisted at the moment of impact, namely, neither to the right, nor to the left, which would necessarily be the case for non-central ground contact.
  • the static adjustment method is the older of the two; It is commonly referred to as “static lie fitting” worldwide.
  • the younger and thus more modern dynamic method, which represents the state of the art today, is called “Dynamic Lie Fitting”.
  • the player expediently proposes several balls of a specially prepared pad, the so-called pickguard or "Lie Test Hitting Board”.
  • the latter is an approximately 1-3cm thick plate, usually made of wood with the dimensions of 1m x 1m. The size should be such that a player standing on the plate can perform the Probeetti.
  • a marking surface is usually incorporated into the plate, which has a color layer, such as graphite, and which provides the sole of the club head with a colored mark in correctly executed golf club, the line of contact of the Sole with the pad represents.
  • the US-A-6,102,811 discloses only a spherically shaped pickguard, with which you can determine where the club head of a golf club touches the ground.
  • the CA-A-2, 312, 587 discloses only one method for determining the contact of the bottom of the racket with a bottom adhesive tape with special markings adhered to a racket sole to determine the area of contact with the ground when struck.
  • the object of the invention is therefore to provide an improved dynamic manufacturing process, with both forged as well as cast or otherwise produced golf clubs are individually tailored to produce.
  • the template process makes the previous fit, i. the change in the Lie angle by bending while maintaining the shaft length superfluous because, for the first time from the outset a racket set can be made with suitable for the user shank lengths and no Lie-change.
  • the evaluation of the test impact by means of the template takes into account for the first time the effect of the deflection of the racquet during impact. This bending is evidently not calculable, but only experimentally ascertainable.
  • the stenciling process will tend to take into account, in particular, the warp deflection found experimentally in the marker on the club head sole, also in the production of a match set from the outset.
  • WtF ground clearance
  • a template is created for the test set which indicates how much the point of contact of the bottom of the racket with the floor is displaced when one and the same test person with rackets, the same loft and lie angle, but other wrist To floor distances have, for example, a golf course on a pickguard.
  • a test person measures the distance of his wrist to the ground in the vertical direction, that is, selects the ground clearance H (or Wrist-to-Floor (WtF)) and a matching test racket if possible.
  • H or Wrist-to-Floor (WtF)
  • the test person performs a few golf strokes with the test racket selected previously on a pickguard.
  • the racket manufacturer takes the according to the template, holding it on the sole of the test racket and reading where the point of contact or line of contact is with respect to the center of the sole.
  • the racket manufacturer reads from a table how long the racket should be considering the correction made with the template and then cuts the shank to the correct length.
  • FIG. 1 schematically shows a golf club with a club head 1, a shank 2 attached thereto and a grip 3.
  • the grip 3 is applied on the end of the shaft 2 remote from the club head 1.
  • the club head 1 has a striking surface 4, which encloses a so-called loft angle ⁇ with a vertical plane corresponding to the plane of the drawing.
  • the loft can range from 10 ° to about 60 °.
  • the touch of the soil takes place at the moment of impact with the sole 5, wherein the Berühung should be done centrally according to the line 0, so that no torque can arise, which would turn the club head 1 to the right or left.
  • the angle ⁇ which includes the shaft 2 with the ground, is the so-called Lie angle, which due to many years of experience the has been assigned to individual racquets of a sentence.
  • Lie angle due to many years of experience the has been assigned to individual racquets of a sentence.
  • An example is again the table below; However, it should be noted that other Lie angle can be assigned to the respective racket.
  • Table 1 below shows these calculated values for four wrist-to-floor values.
  • Table 3 develops from Table 2 if one provides the length L1 with a further correction factor, namely the factor B for the deflection of the club shaft at the stroke, the so-called “toe-down bending", which is shown in FIG .
  • the values in Table 2 for Table 3 are increased by 0.1, for example, for an iron 9 and a 35 "racket from 36.4 to 36.5 and so on.
  • Table 3 Iron no.
  • FIG. 2 shows a template that has been created for an iron 9 and that shows how great is the displacement of the contact line with respect to the center or the zero line for a racket with a ground clearance H or a wrist-to-floor of FIG
  • the reason for this displacement is the curvature of the shank 2 in the impact, as shown in the right part of Figure 3 , which leads to the already mentioned toe-down-bending of the club head 1.
  • Figure 4a-c shows three further templates in which the contact lines for clubs with equal Lie angle ⁇ , but different wrist distance H and thus with other Wrist-to-Floor values not at intervals of ⁇ 0.5 "but directly in Wrist to-floor values are specified.
  • FIG. 4 a shows a template for a 28 "racket of the type iron 9, wherein the center line, which is designated by 0 in the case of the template according to FIG. 2, carries the inscription 28" here.
  • Figure 4b shows a similar template as Figure 4a , but for a 30 "test racket, while the template of Figure 4c is for a 32" test racket.
  • test racket which consists of the same heads, shanks and handles for the selection of the optimally adapted set of clubs the desired racket set was made.
  • the subject performs 1, 2 or more golf beats on a test board. This creates on the sole 5 of the club head 1, a mark indicating that at which point the sole 5 has touched the test board during the blow.
  • the club maker takes a template in the case Figure 4c with the inscription 32 "at hand and puts them on the sole 5 of the club head 1 that cover the sole 5 always existing engravings such as the relevant brand name and possibly the figure for the club head exactly, so that the template 32 "is precisely aligned with the sole of the 32" iron 9 type club.
  • each racket manufacturer can set up their own, product-related tables, according to which he wants to make his rackets. It is essential only that to each Test racket a table exists and that depending on the measured with the inventive template displacement of the contact line on the sole of the club head the right Wrist-to-Floor value and thus the correct table column can be selected.
