Description

  The present invention relates to a game striking instrument for a game object that is moved by hitting or impacting. This includes hockey, golf and baseball.

  This striking device has an extension part simply called “handle” and a grip part, an operation part simply called “stick”, and each game object in the shape of, for example, a sliding tree or a stick-shaped stick, directly mechanically. And a collision part that causes action and coupling. This type of instrument, simply referred to as a striker, is on the market in a variety of structures and is generally known. The collision part is directly exposed to a large mechanical stress caused by a game object appearing at a high speed. In this case, it is basically an impulse-like impact force having very steep rise and fall, and the impact force is transmitted to the stick and therefore to the grip portion. The stick and the collision part are vibrationally shaped objects, and therefore can be excited by the frequency included in the rising and falling of the impulse and can vibrate naturally. Due to the predetermined coupling, this vibration is transmitted to the operating part, in particular to the grip part and thus to the player's hand or arm.

  Such vibrations, depending on their frequency and amplitude, are sensitive to the game process, in particular to distinguish the impact intensity or the speed of bounce, especially as the player desires from time to time. However, there is a possibility that it will greatly hinder the precise determination of the direction of rebound. In particular, it can also have a physically damaging effect on the player. In this connection, a rough and / or coarsely sized attenuation measure has been found to be less effective or insufficient because it generally also impairs the required reflective capacity of the racket. Yes. In addition, this generally impairs the player's “hit feeling”.

  From this, an object of the present invention is to realize a structure that makes it possible to better adapt the vibration behavior to the situation of the game process and the requirements and characteristics of the player.

  The solution to this problem according to the invention is defined by the features of claim 1. The basic refinement and optimization features of the invention are defined in the dependent claims.

  The effect of the features of the arrangement according to claim 1 is based on in particular affecting the natural frequency spectrum of the striking instrument as a whole. The first measure for this is to have a number of characteristic three-dimensional regions, surface regions and / or different surrounding, vibration-related, in particular resonance-related material and / or shape or dimensional parameters. It is to provide a line area. In this case, in practice, as many characteristic regions as possible are provided. These characteristic areas are then arranged in the form of at least one transition sequence, which extends over at least a part of the striking instrument and is arranged in at least one fixed sequence. In particular, it corresponds to a mathematical sequence determined mathematically or also by an algorithm. In this case, in practice, it is important to place a relatively large number of transition sequences once again on the striking instrument.

  These spaced apart characteristic regions are therefore also located on, along or in the percussion instrument, so that these transition sequences are divided into vibrating objects. Is the body. This is different from the original, i.e. undivided, oscillating object, in particular, generally higher natural frequencies, and also the natural frequency rise, i.e. correspondingly changed natural frequencies. Will result in a frequency spectrum. In this case, the degree of density of the natural frequencies and the distribution in the related frequency band are based on the functional requirements given to them, and various measures are taken to form this configuration in various ways. Can be modified and adapted or optimized by determining the dimensions of these regions and their transition series and selecting materials.

  Due to the steep rise and fall over time, in the case of impacts with impact impulses where the energy is distributed over a wide frequency band, the change is generally based on the spectrum given here, centered at a higher frequency The natural frequency of the hitting instrument will be excited at a correspondingly higher frequency distribution. However, if the frequency of a given vibration energy increases, the vibration amplitude decreases, so the vibration amplitude is in any case generalized by structuring the vibrating object as a transition sequence of characteristic regions. To reduce. However, since it is a vibration amplitude that can be perceived by the player in particular and does not impair the quality of the game, the basic configuration according to the present invention is suitable as a solution to the problem of the present invention.

  The method of operation and advantages of the present invention, and the features of the basic improved configuration will be described in more detail based on examples schematically drawn in the drawings.

  As an example, the striking instrument shown in FIG. 1 has an operation unit BT and a collision unit PT that directly acts and couples with a game object, for example, a pack in an ice hockey or a ball in a grass or field hockey. These parts are equipped with structures that affect the natural frequency spectrum, and each of these structures is composed of a single transition sequence of a number of characteristic three-dimensional areas, surface areas, or line areas. . These characteristic regions are different in at least one material parameter and / or shape parameter or dimensional parameter, which are related to vibration, in particular related to resonance, in particular at least a part of their respective circumferences, It has the feature that it is distinguished by different weight density, stiffness against deformation and / or damping. Within this transition sequence, the characteristic regions constitute at least one sequence in a certain order, each extending over at least a portion of the strike instrument.

  A first transition series A1 having a characteristic region or vibration member F1 is developed in the vertical direction of the operation unit BT, for example.

  Here, these vibrating elements are formed as layered layers of material, including metal, for example, which is durable with respect to its surroundings, painted, for example, by silk screen printing (Siebdruck).

  The characteristics of this transition series A1 are determined by joining together a number of characteristic regions or vibrating members F1 in series at equal intervals. These intervals are changed for each series, and by dividing the length of the operation unit into an integer number of predetermined parts, in detail, the part length of the operation part is roughly shown in FIG. This is determined in the sense of changing the mutual interval between characteristic regions corresponding to harmonic sequences having relative values of 1/2, 1/3 and 1/4. For the sake of clarity, the splicing based on these three first lines is not depicted in FIG. In practice, such structuring generally involves a very large number of relatively finer subdivisions, for which purpose in this case the characteristic regions are correspondingly reduced in small dimensions. Or the dimensions of the planes of these regions need to be changed further.

  The impingement part PT likewise has a characteristic area and, in particular, is again spliced and has a structure A2 which is effective against vibrations, each in the form of a number of equally spaced transition sequences. This structure can be formed as in the operating section here, and only the outline is shown in FIG.

  In this connection it is pointed out that such splicing can realize not only a gradual increase or decrease, but also a gradual change or sequence that changes in an iterative manner (Oszillatorisch). For example, in FIG. 1, the changing value is given by the spacing between characteristic regions. According to this, even with these small numbers of splicing or transition sequences, there is a repetition between increasing and decreasing between the characteristic regions of the 1/3 and 1/4 sequences. Where the spacing between the two is minimized. However, in the framework of the idea of the invention, and advantageously in some cases, it is possible to repeat a form with or without a little or little seaming by means of a direct definition of the magnitude of the vibration parameters and the construction of the sequence. Fluctuating changes can also be realized.

  Quite generally, with regard to the effect according to the invention, vibration parameters other than the spacing between the characteristic regions, such as material parameters and / or shape parameters or dimensional parameters, in particular different weights, weight densities, stiffness against deformation and / or Or attenuation etc. are also considered. However, by varying them in at least part of at least one transition sequence so that an effective structure against vibrations with multiple natural frequencies is formed, or possibly constant, or It is basic to use them in combination. In this case, at least partly and at least approximately a harmonic sequence, and also corresponding to a geometric sequence, a series of transitions extending over at least five parts, in particular in the form of spliced together, Of particular importance are structured transition sequences that are effective against such vibrations. In basic use, a transition sequence that extends over at least five parts, in particular a plurality of structured transition sequences that are spliced together and effective against such vibrations, is aimed at. It turns out that it is suitable or even necessary.

FIG. 2 shows an example of a transition series of regions that change based on the geometric sequence in the tubular grip portion. Here, planar, ring-shaped vibrating elements or characteristic areas F2, which are spaced apart from one another in the longitudinal direction of the tube, for example consisting of a flake containing metal or a silkscreen printing layer containing metal, Arranged outside. While these members F2 have the same width a1, their intervals are set based on the geometric sequence x, x ² , x ³ ... (X <1) that gradually decreases.

FIG. 3 shows the use of the geometric sequence again, but the interval a2 between the vibrating members or characteristic regions F3 arranged in a certain order in the longitudinal direction of the tube is constant, but here the width thereof is shown. Are set on the basis of the gradually decreasing geometric sequence x, x ² , x ³ ... (X <1). Such members are, for example, arranged in a perfectly matched manner not only on the outside of the tube but also on the surface of the internal cavity.

  FIG. 4 shows the vibration member R on the tubular operation portion BT, which is characterized by a characteristic region that is three-dimensionally expanded. These vibrating members or characteristic areas can be understood as engraved sinks made of material with a relatively high weight density, for example, on the outer wall surface of the operating part BT.

  These vibrating members are arranged as two multi-dimensional, basically orthogonal transition sequences, that is, in the axial direction of the tube based on the arrow P2 and in the circumferential direction of the tube based on the arrow P3. This means that it is very different from the joints arranged in one direction, respectively, according to FIG. This variation can have separate and possibly harmonious effects on the waves traveling in the longitudinal direction of the tube and the circumferential direction of the tube, or standing waves that develop in these directions. It is what.

  In the case of the golf club based on FIG. 5, the operation part BTG consisting of the handle ST and the grip part H and the thick rod-shaped collision part PTG are roughly shown. This handle has a thick portion V arranged in the longitudinal direction as a transition sequence with respect to the axial spacing and the axial width and / or radial thickness. These thick portions act as characteristic areas or vibrating members in the sense of the present invention. Here, it is a multiple splicing structure in the sense described above having an equidistant arrangement structure, and each of these equidistantities constitutes a single harmonic number sequence or a plurality of harmonic number sequences as a whole. . This is also true for the golf club according to FIG. 6, where the handle ST again has an array of thick ring-shaped portions R, which are formed as discrete ring-shaped objects. Therefore, each is concentrated on the axial region that develops in the vertical direction of the handle.

  The baseball bat depicted as an example in FIG. 7 has a handle-shaped operation portion BTB and a collision portion PTB formed in a substantially cylindrical shape having a ring-shaped characteristic region or vibration member SB. These regions or members are arranged in a certain order in the longitudinal direction of the cylinder while changing the interval between them, and have dimensions that are changed in the axial direction or the radial direction. In some cases, the outer surface of the cylindrical collision portion is kept smooth anyway, and this can be realized by appropriately configuring the outer surface of the ring-shaped vibrating member. These ring-shaped objects can be produced, for example, by splitting or cutting only one side, and then fitted or inserted into the corresponding ring groove of the impingement part. It is also conceivable that the plastic collision member is fitted in a shape-coupled form and the other is covered with an outer hollow cylindrical covering member. In view of the generally higher weight baseball bats, the material of the vibrating member advantageously has a relatively high weight density.

  In a variant of the embodiment of the baseball bat according to FIG. 8, the characteristic region is formed as an annular depression ESZ around the impact part PTBa and is covered by a cylindrical covering HL. Between these recesses, characteristic regions or vibrating members are formed, which are related to the mutual spacing or axial spacing of one or both ends of the structure. A plurality of at least approximately equidistant transition sequences of characteristic regions are joined together. This makes it possible to achieve fine-tuned adaptation based on various optimization requirements.

  A variant of the embodiment of the baseball bat according to FIG. 9 is formed, for example, by a hollow ESA around the cylindrical impact part PTBb and in the axial direction and also covered by a cylindrical covering member HL. A vibrating member or characteristic area is shown. Again, these vibration members are at least approximately equally spaced as a whole, but here are a series of a plurality of transition sequences of these characteristic regions that develop in the circumferential direction of the collision portion. With such a structure, clear optimization can be realized even in a relatively short collision part.

  Furthermore, combinations or seams of structures based on FIGS. 8 and 9 are also conceivable. This forms a number of radially projecting vibrating members having an angular or rounded cross-section with respect to the cylindrical cutting surface in the impingement or inside the covering member. This is an arrangement that has a great effect on vibrations or resonances, and that arrangement can have a great influence on the natural frequency spectrum of the percussion instrument.
