The specific embodiment

Tennis racket 1 among Fig. 1 is made of following: a tension force frame 2 that forms racket head has String of a musical instrument grid 3 is disposed thereon, and string of a musical instrument grid 3 is made racket by many strings of a musical instrument that cross one another Neck or racket spools are connected to tension force frame 2 or its tension force frame profile 2 ' or the 2a ' (figure of heart section more than 5 2-5), at this axle racket handle 7 is being set. Tension force frame profile 2 ' or 2a ', heart section 5 are by two Individual arm 5 ' stretches out and separately forms from Handle axis 6. Handle axis 6 and heart section are linked to be the ball of a single-piece Racket frame is made to a hollow body or hollow frame in the embodiment shown, and this framework is to covering Close and made by a kind of suitable material such as fibre reinforced plastics, have one along its whole length pair The hollow profile of outer closure.

Shown in Fig. 2 and 3, on the tension force frame 2 or tension force frame profile 2 ' in string of a musical instrument grid 3 outsides Be provided with whole along the tension force frame 2 between 5 liang of arms 5 ' of heart section of external force buffering support profile 8 Long limit surrounds tension force frame 2 or tension force frame profile 2 '. In the embodiment shown, support profile is 8 pairs Claim in string of a musical instrument grid plan BE and be one to the lid shape profile cross section 9 that string of a musical instrument grid 3 is opened, It leaves on the outside of string of a musical instrument grid, in the district of the string of a musical instrument grid plan BE of the cutaway view of Fig. 2 and 3 The outer surface that an indent is arranged in the territory, the depression 10 that forms a groove shape surrounds racket head in the outside Or tension force frame 2. In depression 10 both sides, profile cross section 9 has an evagination basically on the outer surface Arch upward, therefore form two parts in the both sides of string of a musical instrument grid plan BE, these two parts are at its face Inboard to string of a musical instrument grid respectively has the depression 11 of an indent flat along the whole length of support profile 8 Row extends in depression 10. In addition, support profile is one of profile cross section 9 frame oriented profiles 2 ' The bossed sleeve of system or eyelet member 12 on the side. Eyelet member 12 is inserted through on the framework profile 2 ' The

hole

13 and 14 that gets out, the boring 13 and 14 same axis that have on string of a musical instrument grid plan BE. Eyelet member 12 itself has boring 15, and by this boring 15, the string of a musical instrument 3 ' is with usually on tennis racket The mode of wiring is guided, and the relevant string of a musical instrument 4 is stretched by the boring of eyelet member 12 by given direction Go out, then in depression 10 along the outer side shifting of tension force frame, pass through again another eyelet member downwards 12 or its boring 15 and so on. Adopt eyelet member 12, support profile 8 can be in certain limit On the axis direction of eyelet member 12, framework profile 2 ' is regulated. Therefore tension force frame 2 is at least one at it Be to be made by two parts on the partial-length. Support profile 8 is all peripheral along framework 2 by one The single-piece of extending is made.

Shown in Fig. 2 and 3, profile 2 ' is in its outside towards profile cross section 9, at string of a musical instrument net for another example The both sides of lattice plane BE and the place of leaving its distance are shaped with a groove depression 16 and depression 11 Corresponding. In depression 16 or cave in 11, the outer surface of framework profile 2 ' and support profile 8 or There is a flexible member 17 to prolong along the whole length of support profile between the inner surface in profile cross section 9 Stretch. When support profile 8 was in not tensioning state, profile 2 ' was left in two outsides in profile cross section 9 A distance (Fig. 2), and after tennis racket 1 wiring, specifically namely after the string of a musical instrument 4 wirings, bullet Property element 17 is pressurized, produces between the inner surface of the outer surface of framework profile 2 ' and support profile 8 Give birth to the effect of a flexible or damping, make support profile 8 at the regional inner close fitting at edge 9 ' in type Therefore on the outer surface of face 2 ', between the outer surface of framework profile 2 ' and support profile 8, form The space is closed, thereby such as pointed being applied by string of a musical instrument grid 3 or the string of a musical instrument 4 of arrow K among Fig. 3 Tension force just can transfer on the profile 2 ' by support profile 8 and elastic deformation component 17. Element 17 The effect of not only playing tension element can be used to keep the tension force of the string of a musical instrument, but also particularly conduct Damping element, it can provide momentum when pellet impact is played ball to string of a musical instrument grid or with tennis racket 1 Flexible damping also can prevent the vibrations, vibration of the interference on the games racket frame etc. simultaneously.

Flexible member 17 can be made by elastic rubber material such as plastics, can have circular cross section and Corresponding length. Preferably not only want flexible performance when selecting the material of flexible member 17, and want There is damping capacity can consume the performance of kinetic energy.

Element 17 can also be sebific duct, for example can fill within it with fluid, gas or admixture of gas, air or inert gas (such as nitrogen or CO₂) then closely sealing. These sebific ducts can be at confined state (figure 2) namely before the string of a musical instrument 4 tensionings with certain exert pressure, or keep not pressurized.

When element 17 is filled with liquid medium, when for example containing the medium of oil and/or water, can obtain Special effect. Hit on string of a musical instrument grid and the tension force of maximum is applied to when ball in this case In the time of on the string of a musical instrument, can provide at short notice one inwardly towards the string of a musical instrument in this position upper support profile 8 The power of grid; And on string of a musical instrument grid 3, not being subjected to or few affected zone, because the liquid of displacement Medium, support profile 8 is pressurized by element 17, has the outward force of increase, therefore can increase The tension force of the string of a musical instrument. When pouring into gas, this effect generally also can take place. So just cause one Individual to tennis racket 1 effectively complete new performance.

In the superincumbent explanation, suppose that element 17 is totally continuous elements. But also may divide Become several independent elements, connect and fixing so that assembling in the direction of support profile 8 then.

In addition, may make element 17 become the part of total profile, for example can pass through a cross bar will Two elements 17 link together and become the profile cross section, shown in dotted line among Fig. 2 19. Moreover, can Can be with element 17 built on the framework profile 2 ' or on the support profile 8.

As mentioned above, support profile 8 must be transferred to side force K by deformation element 17 On the framework. But simultaneously, support profile 8 or its profile cross section 9 at least in the zone at edge 9 ' still Enough elasticity should be arranged, make that support profile 8 can pass through element 17 when string of a musical instrument grid 3 is subjected to impacting Distortion make inside damped motion. The material that is applicable to support profile 8 is fibre-reinforced moulding Material, metal or contain metal and the composite of plastics. In order in 9 ' zone, edge, to keep required Elasticity, profile cross section 9 can be constructed like this, for example leaves edge 9 ' for the transfer of exerting all one's strength terminates in Enough place far away and the minimizing thickness that needs and/or strengthen the profile cross section. This problem can have many Plant solution.

When the profile cross section of support profile was made of metal, eyelet member 12 preferably was made of plastics also Be inserted into or be formed in the respective aperture in profile cross section 9. In general, always can be eyelet member Selecting a kind ofly more has flexible and flexible material than profile cross section 9.

Eyelet member 12 is in the insertion point or the certainly seal frame profile 2 ' closely of 13 or 14 places of holing Inside.

Shown in Fig. 2 and 3, tension frame profile 2 ' forms the supporting table of inclination in its exterior lateral area Face 2 ", carrying the zone at edge 9 ' in the profile cross section 9 of support profile 8, this inclination on it Face and string of a musical instrument grid plan BE form an angle less than 90 ° and open wide to string of a musical instrument grid 3. Like this When the string of a musical instrument is tensioned with respect to the tension force frame under the strain in profile cross section 9, can reduce above-mentioned The motion of support profile 8.

Figure 4 and 5 illustrate another possible embodiment, and this is a tennis racket, wherein tension force frame 2a At least be designed to be made up of two parts at its partial-length, in fact a part seals Hollow frame 2a ', another part are support profiles 8.

The embodiment of Figure 4 and 5 and Fig. 2 and 3 embodiment relatively, main is not both: at frame Do not adopt boring 13 and 14 among the frame profile 2a ', but the outside from framework profile 2a ' is prolonged Reach inboard diameter and become gradually big opening 20, this opening 20 is by towards framework profile 2a ' inside Funnel-form wall section 21 sealing. Therefore only have the 12 quilt plants of short eyelet member in opening 20. Because opening becomes big at least gradually on perpendicular to the cross-sectional axis of string of a musical instrument grid plan BE, therefore The corresponding string of a musical instrument 4 can not have lateral displacement when being at play, because above-mentioned change is just meaned greatly actually The expansion of shock surface or string of a musical instrument surface mesh.

Fig. 6 and 7 is for similarly to scheme with Figure 4 and 5, a tennis racket shown in the figure pass through tension force The cross section of frame 2b. Tension force frame 2b has a framework profile 2b ' suitable with framework profile 2a ' With a support profile 8b that function is suitable with support profile 8a. In the embodiment of Fig. 6 and 7, institute What adopt is not flexible member 17, and be provided in a side of string of a musical instrument grid plan BE both sides, in tension force frame type Flexible member 17b between face and support profile 8b or its wing profile cross section 9b. Two elements all For rail-like and all extend along the whole circumference of tension force frame 2b, the tension force frame is by frame on this circumference Two parts of frame profile 2b ' and support profile form. In the embodiment shown, flexible member 17b by Elastomeric material such as resilient plastics or rubber are made.

The suitable shape of flexible member 17b reaches and forms between framework profile 2b ' and support profile 8b The suitable shape of space 18b can when the string of a musical instrument 4 is subjected to tension force, decide, at that time will be with these The support profile 8b that the string of a musical instrument is fixed on the tension force frame 2 will be supported on the framework profile 2b. Work as bullet Property element 17b still leaves the gap, namely during by strain between flexible member 17b and the string of a musical instrument Flexible member 17b does not touch the string of a musical instrument, as shown in Figure 6.

But in being at play when racket be subjected to ball strike, have very large tension force to be applied to string of a musical instrument grid Or on indivedual strings of a musical instrument the time, the strain of flexible member 17b will be increased to as shown in Figure 7 These elements 17b is pressed on the string of a musical instrument 4, along with the increase that is applied to the external force on the string of a musical instrument, bullet The property element the power that compresses also increase, therefore can be firmly the fixing string of a musical instrument 4 diametrically, this not only makes ball Bat or tension force frame can use when being at play well, and can suppress the vibration of the string of a musical instrument, thereby also press down The vibration of the tension force frame that system causes therefrom.

Supposition damping element 17b is two elements that separate in the superincumbent explanation, but also may with They make an independent rail-like element, have opening on it and can insert the string of a musical instrument.

Fig. 8 one similarly scheme with Fig. 6 and 7, passes through the tension force frame 2c of a tennis racket shown in it Cross section. Tension force frame 2c has a framework profile 2c suitable with framework profile 2b ' and one The support profile 8c that function is similar to support profile 8b. Flexible member 17 is located at tension force frame profile 2c ' And between support profile 8c or its wing cross section and be located at respectively the both sides of string of a musical instrument grid plan BE. Support profile 8c is made by a single-piece of extending along framework 2 whole peripheries. Element 17 Can be made by the material with permanent elasticity or elastomeric material, because its elasticity, it can give the string of a musical instrument Required tension force is provided.

Also be provided with another one unit in the zone of string of a musical instrument grid plan BE between two elements 17 Part 17c, it is bearing in the inboard of support profile 8c on the one hand, and is shelved on the other hand tension force In the groove depression on the frame profile 2c '. In the embodiment shown, element 17c be not subjected to tension force State under have the cross section of a circle and extend this element along the total length of support profile 8c Made by the material with damping capacity, this material can suppress the motion of the string of a musical instrument, also can suppress tension force The motion of frame is such as vibration, impact etc. Therefore element 17c material therefor is so a kind of material, it Can be out of shape, but when distortion, will consume kinetic energy.

When element 17c has continuous form, this element contain perforation so as to insert the string of a musical instrument or String of a musical instrument eyelet member. But also element 17c may be made several independent elements and be distributed in tension force frame 2c Circumferencial direction on, at this moment element 17c just must be located between the string of a musical instrument eyelet member.
