The specific embodiment

At first with reference to Fig. 1, racquet frame 10 according to an embodiment of the invention is shown comprises head 20, cylindrical member 30, two arms 40 and handle 50 (being depicted as brachymemma).Two arms 40 provide the connection between head 20 and the handle 50.

As Fig. 4 know illustrate, head 20 is breach frames of hollow, the remainder of the ring on its end 24 and the breach both sides that are limited with gap 22 is therebetween compared cross-sectional area and is reduced.Both sides adjacent with gap 22 on head 20 is formed with two through hole 26.The opposite face that ring is directly passed in hole 26 is with the hole of the paired aligning that is formed for attached coupling part, as after this with reference to as described in Fig. 3.Head 20 is compatibly made by fiber reinforcing material such as fiber reinforced plastic material or suitable metal or metal alloy.

The free end of head 20 or terminal 24 links together by cylindrical member 30, and cylindrical member is the form of pipe as shown in Figure 4 or the solid that has depression at each end.The internal diameter of pipe or depression is identical with terminal 24 external diameter basically so that terminal 24 be placed in the member 30 in the sleeve pipe mode.

Two terminal 24 of member 30 and head 20 passes through suitable glue or other adhesive, perhaps twines by the joint that the curable materials band is centered on pipe 30 and head 20 and makes the curing of material band then, so that member 30 and head 20 are combined.

Cylindrical member 30 can be made so that unique outward appearance to be provided by the transparent or semitransparent material such as nylon or plastics.Member 30 also can be made by the opaque material such as metal or metal alloy or opaque plastics.

Two arms 40 respectively have main part 42 of extending from handle 50 and the coupling part 44 that is connected and forms connecting elements between main part 42 and the head 20 regularly with main part 42.Coupling part 44 is provided with the bent hole 442 of longitudinal extension, and the free end of head 20 passes this bent hole.This part of coupling part 44 is provided with from the coupling part 44 periphery and extends to a plurality of holes 444 in the bent hole 442.One of through hole 26 in each hole 444 and the head 20 is cooperated being formed for that two-piece type fixture 12 is received in wherein locating hole, as Fig. 3 know illustrate.Fixture 12 (Fig. 3) is combined to form by cloudy bolt 12a and positive bolt 12b's.To observe hole 26 from Fig. 3 and have outside 26a, this outside diameter is fixed the effect of immersing oneself in of a 12c on two bolt 12a and the 12b greatly with formation than the diameter of inner 26b.

Therefore, for the coupling part 44 with arm 40 is attached to head 20, the free end of head 20 passes the hole 442 of coupling part 44 and passes through cylindrical member 30 attached together.Slide up to the hole on the coupling part 44 44 with till the hole 26 on the head 20 is aimed at around head 20 in coupling part 44 then.In case aim at, but positive bolt 12a and each side of cloudy bolt 12b ground patchhole 444 and pass hole 26 and can merge up to them and be threaded togather so that coupling part 44 is fixed to head 20.

The main part 42 of two arms 40 of handle 50 forms for example part.Main part 42 is connected to coupling part 44, therefore handle 50 is connected to head 20.Coupling part 44 respectively has straight part 162 and extends and extend to the sweep 164 of an end of straight part 162 from a side.The other end of straight part 162 is provided with cavity 166.The main part 42 of two arms 40 has projection 45, cavity 166 complementations of this projection and coupling part also are used for

part

42 and 42 is linked together, such connection can be used glue or other adhesive that is fit to, and perhaps twines by the joint that the curable materials band is centered on

part

42 and 44 and the material band is solidified so that coupling part 44 and main part 42 are linked together to realize.

Coupling part 44 can be made so that unique outward appearance to be provided by the transparent or semitransparent material such as nylon or other plastic material that is fit to.Coupling part 44 also can be made by the opaque material such as metal or metal alloy or opaque plastics material.

Because head 20 and two arms 40 are connected to each other by fixture 12, so when head 20 damaged, the user can unclamp fixture 12 the head 20 of fracture is pulled out the bent hole 442 of two arms 40.Then, new head (using new pipe 30 if desired) is installed on two arms 40 so that racquet frame 10 is available once more.

In addition, adopt this racquet frame, when the user uses the racket square stance, because head 20 and arm 40 are members independently, only the sub-fraction of shock energy is delivered to handle 50 through the interface of head 20 and two arms 40.Racquet frame 10 can reduce the shock energy that is delivered to the user.Specifically, coupling part 44 can be made to strengthen the vibrations inhibitory action of racquet frame 10 by elasticity or vibration absorptive material.

Manufacturer can change the color of head 20, pipe 30, coupling part 44 and handle 50 or material so that racquet frame is unique.

Relate generally to tennis racket although should be appreciated that described embodiment, be to be understood that the present invention also can be used for other other racket such as wall ball racket and racket.
