The specific embodiment

In the accompanying drawings, reference number 10 represents generally according to physical training apparatus of the present invention.In the present embodiment, physical training apparatus is that tennis training is an application example for the exercising device of the ball game form of band net.

Exercising device 10 comprises substrate 12, is used for installing at supporter.In this example, substrate 12 is installed in the upper along part of the net 14 (shown in Fig. 2 A to 2C) used such as the tennis court.Exercising device 10 also comprises bar 16, is connected on the substrate 12 according to the mode of partly stretching out outside the substrate 12 to major general's one, thereby when substrate 12 is installed on the net 14, makes bar 16 can reach the top of net 14, shown in Fig. 2 B.

One end of elastic rope 18 is connected to bar 16, and ball 20 is connected to the other end of elastic rope 18.Ring 19 (shown in Fig. 3 and 5) are connected to ball 20.Connector 21 such as clip or change is connected to each other ball 20 and rope 18.Connector 21 allows ball 20 to rotate centered by pivot with respect to elastic rope 18 or spins, and this helps to prevent that rope 18 from twining and entanglement.

Bar 16 is placed suitable position, thereby moving (shown in Fig. 2 B) to the direction away from net 14 at ball 20 causes rope 18 to stretch in the situation of long or tension, when rope shrank, bar 16 and rope 18 can be worked in coordination with and be promoted that ball 20 oppositely returns (shown in Fig. 2 C) above net 14.

Substrate 12 is rectangular slab normally, is provided with in the horizontal the groove 22 of relative both sides indent on the substrate 12, is used for rope 18 is wrapped in substrate 12, consequently makes apparatus 10 be convenient to deposit.

It is porose 24 that substrate 12 also arranges, and it is normally circular, and the shape in hole 24 and size are suitable for holding tennis 20 in the mode of frictional fit, equally also are convenient to deposit apparatus 10.Groove 26 extends to take in the part rope 18 of close tennis 20 from circular port 24.

The length of substrate 12 between 300 millimeters to 400 millimeters, for example about 360 millimeters, and transverse width is between 200 millimeters to 300 millimeters, for example about 240 millimeters.

Substrate 12 can be multiple different material, and for example substrate 12 can be wooden, moulded plastic or composite, for example glass fiber compound material or carbon fibre composite.

Substrate 12 also defines the hole 28 that is roughly T shape, to form a carrying handle 30.In use, be with 32 to pass T shape hole 28, the lower end so that substrate 12 is used is fixed on the tennis net 14, with the inclination in use of opposing substrate 12.Be with 32 to contain picture Velcro ^TMSuch colludes-ring structure, is used for the lower end of substrate 12 is fixed on tennis net 14.The width in T shape hole 28 approximately is 2.5 centimetres.

Substrate 12 comprises a clamping device 34, is used for substrate 12 being fixed on the upper edge of net 14, shown in Fig. 2 A to 2C temporarily.

Apparatus 10 comprises joint 38, is used for barre 16 and is connected to substrate 12.Bar 16 is rotated centered by pivot between operating position and off-position joint 38 or by hinge through, wherein the operating position is that bar 16 reaches the top position of net 14 when substrate 12 is fixed on the net 14; Off-position refers to that bar 16 reaches the below of supporter, returns to avoid stymy 20 to cross net 14.In Fig. 2 A to 2C with arrow 17 indicating arms 16 rotatablely moving centered by pivot.

Joint 38 comprises a passage that is used for taking in bar 16 that is limited by stationary pipes 40; With counter-sunk screw 37 or similarly screw pass hole 43 cramp bars 16 and be fixed in the stationary pipes 40.Like this, bar 16 is dismountable, unclamps and takes away so be easy to barre 16.In addition, can by unclamp counter-sunk screw 37 and in stationary pipes 40 sliding bar 16 come the effective depth of adjusting lever 16 above net 14.Be understandable that, the height of bar 16 can be regulated with additive method, for example bar 16 is made the form of expansion link.Highly regulate the style that allows apparatus 10 adaptation users, and harmonious with the characteristic of required ball flight.

Joint 38 comprises a pillar 39, is installed on the substrate 12 and from substrate 12 and stretches out, and stationary pipes 40 utilizes whirligig or hinge mechanism 41 to be installed on the pillar 39.

In the situation that bar 16 shortenings, when bar 16 turns downwards by pivot, the bottom that the leg 29 in T shape hole 28 holds bar 16.The width of leg 29 between 20 millimeters to 30 millimeters, for example approximately is 25 millimeters greatly.The length in T shape hole 28 is about 150 millimeters-250 millimeters, for example about 200 millimeters.

The stop of a stopper (stopper) 35 forms is installed on the substrate 12, and stopper 35 is placed between joint 38 and the upper end 45 of substrate 12 when work.The direction of clamping device 34 is configured to when substrate 12 is installed on the net 14, and joint 38 and stopper 35 are placed on the longitudinal axis of substrate 12, and stopper 35 is above joint 38.Therefore, when bar 16 with axle pivot steering or when being turned back to its stand up position, stopper 35 is in the position that stops bar 16, stopper 35 is cylinders usually, uses that resilient vibration-absorptive material forms as rubber.

About at a distance of 80 millimeters to 100 millimeters between joint 38 and the stopper 35, for example about 110 millimeters.Be understandable that, select the distance between joint 38 and the stopper 35, make the serviceability of bar 16 best, so that it provides required strength for together the backhaul of ball 20 with rope 18, therefore, also can select other distance between joint 38 and the stopper 35.

Specifically, joint 38 and stopper 35 are separated, when throwing up, cause ball 20 to apply a power and to produce the individual effect of whipping at bar 16, bar 16 bump stoppers 35 and crooked return ball 20.

In addition, when returning after ball 20 is correctly impacted, the height of bar 16 helps to guarantee that ball 20 can skip net 14; When ball 20 returns, rope 18 absent-mindedness, at least because the effect of bar 16 centers of gravity and the help of stopper 35 reaction forces are overturn bar 16 downwards, like this, the top that ball 20 is crossed net 14 is returned and is not subjected to the obstruction of bar 16.

Rope 18 is solid, is made by latex or rubber.The diameter of rope 18 is about 2 millimeters to 4 millimeters, for example 3 millimeters.Rope 18 can change tubulose into, and its quality is less than the similar solid rope of size like this, and elasticity is similar to solid rope.In this example, rope 18 is outer, and its internal diameter is about 2 millimeters to 4 millimeters through being about 3 millimeters to 5 millimeters, and rope 18 is about 4 meters to 5 meters.But be understandable that this length can change according to practical application.

Put it briefly, when tennis 20 is hit overpass net 14, rope 18 is elongated or upholds, make rope 18 be tightened up or be tauted, bar 16 applies a pulling force can for rope 18 as a result.Described in following more detailed description, bar 16 is constituted as with rope 18 and cooperates, and allows tennis 20 cross net 14 and returns.

Bar 16 is with suitable material extending or fashions into, such as graphite, carbon fiber or glass fibre etc.When ball 20 is hit overpass net 14 and away from bar 16 during with rope 18 tension, these materials allow bars 16 to depart from its original-shape or elastic bending, for example configuring suitable bar 16 can be similar with the pole that fishing is used.Therefore, bar 16 can be glass fiber compound material, and other suitable material comprises plastics or metallic article, for example spring steel and aluminium alloy or aluminium alloy.Be understandable that, the size of bar cross section will be according to using material type to change.

The length of bar 16 is about 400 millimeters to 700 millimeters, for example is about 580 millimeters, and from its in the lower end in when work the upper end during to its work tapered.When bar 16 was made by glass fiber compound material, its base diameter was about 5 millimeters to 9 millimeters, for example approximately 9 millimeters; Its top diameter is about 1 millimeter to 5 millimeters, for example is about 3 millimeters.

End at bar 16 also comprises pivoted loop or pivot mounting 64 and encircles 66, encircles 66 and is used for rope 18 is connected to pivoted loop 64.Pivoted loop 64 allows ring 66 rotations, to adapt at least to a certain extent the rotation of ball 20, avoids rope 18 excessively to twine and causes entanglement.Be to be understood that rope 18 also can pull down from installed part 64 when needed.For example, rope 18 can tie up on the installed part 64 or from installed part 64 and untie.Therefore, can predict apparatus 10 can be equipped with also and can not be equipped with rope 18 and/or ball 20.

With reference to figure 3, Fig. 3 has shown athletic training external member 50, and it comprises tennis racket 52, and the exercising device 54 of another embodiment of the present invention.External member 50 also comprises the packaging bag (not shown), and its shape and tennis racket cover are similar, is used for packing tennis racket 52 and tennis training apparatus 50.With reference to figure 1 and Fig. 2, identical reference number refers to identical part, unless otherwise specified.

Fig. 6 and Fig. 7 have shown approximate relative size and the orientation of exercising device 54 assemblies.Particularly, the selection of size A, B, C can produce materially affect to the mode of this exercising device work.

Size A is height or the length of stopper 35; Size B is that the surface 132 of slave plate 58 is to the distance of stationary pipes 40 center lines 130; Size C is that the rotation 134 of bar 16 is to the distance of the stopper 35 in bar 16 Plane of rotations.

In the present embodiment, distance A is about 30 millimeters to 40 millimeters, for example 33 millimeters to 37 millimeters; Be about 35 millimeters to 50 millimeters apart from B, for example 35 millimeters to 40 millimeters; Distance C is about 90 millimeters to 100 millimeters.In one embodiment, select size A and B, so that when bar 16 is resisted against stopper 35, the major axis of bar 16 departs from the angle of end 45 of plate 58 between the 0-10 degree, and for example 5 spend.In addition, chosen distance C suitably whips or dynamic bending so that bar 16 is produced.

Fig. 8 and Fig. 9 illustrate two different examples of plate 58 structures.In Fig. 8, plate 58 is cast into groining shape, and the rigidity of this model 58 is similar with real central layer, but does not have real central layer heavy.In Fig. 9, plate 58 can be real core, also can adopt the mode that adds a backboard 112 at plate shown in Figure 8 from consideration attractive in appearance.

In use, when the user wants to train, just untie rope 18 from substrate 12, and be fixed on the upper along part (shown in Fig. 2 A to 2C) of tennis net 14 with clip 34 with 32 substrates 12.

During rest, bar 16 is placed the position 16.1 shown in Fig. 2 A; When the user impacts tennis 20 when crossing tennis net 14 with enough strength, tennis 20 is tightened rope 18, and the rope 18 of tightening then is pulled to its stand up position with bar 16.When bar 16 moved into the described position of Fig. 2 B, the start position of above-mentioned movement was shown in 16.2 among Fig. 2 A.

When bar 16 arrives its stand up position, be pressed against on the stopper 35, and in rope 18 tensions, further tightrope 18 so that bar 16 buckle from original shape, shown in Fig. 2 B.

When the inertia of tennis 20 exhausted under the impact of elastic rope 18, bar 16 returned its original shape, thus as a result bar 16 tows 18 lifting the balls 20.Like this, use and impel ball 20 to cross tennis net similar in appearance to the action of whipping to return, shown in Fig. 2 C.

Returning of tennis 20 can make the user repeat to impact tennis 20 with the movement of the bar 16 shown in the arrow 17.

In addition, described exercising device allows tennis to snap into the opposite side of net before turning back to user's one side.Like this, when playing ball, can allow the user infer he or she the degree of accuracy.When the user only trained facing to wall, this point was irrealizable.

Be understandable that the selection of relative dimensions, weight and material determines exercising

device

10,54 operating characteristic.

For example, the average height of actual tennis net is about 90-94 centimetre, so the ball 20 that the length of selector 16 will be convenient to return is crossed net.As mentioned above, when bar 16 impacts stopper 35, an angle is arranged between bar 16 and the plate 58.Select this angle so that when rope 18 unclamps bar 16 sagging immediately under Action of Gravity Field so that ball 20 is crossed net 14 passback and can not bumped against bar 16.

In addition, in one embodiment, the gross weight of selector 16 and pivoted loop 64 is approximately lighter by 8% to 12% than ball 20, and for example 10%.This weight and above-mentioned angle help bar 16 sagging within the very short time, to avoid stymie 20 together.

In one embodiment, pivoted loop 64 is than bar 16 weights, and for example, the about 4-6 gram of the weight of pivoted loop for example 5 restrain, and the weight of bar 16 lightly, approximately the 1-3 gram.Therefore, the weight of pivoted loop 64 and above-mentioned bar 16 help bar 16 to withdraw from the return route of ball 20 with respect to

substrate

12,58 angle together.In this embodiment, the weight of ball 20 is about the 60-70 gram, for example 66 restrain, and the weight of selector 16 is about the 10-20 gram, for example 16 grams.

Be understandable that, ball 20 allows ball 20 to come and go above net according to the mode of nature than rope 18 with bar 16 relative high weight.In addition, the selection of relative dimensions, weight and material allows bar 16 according to consistent and stably pendulum model manner of execution swing, so that the sportsman forms a kind of rhythm, simultaneously still in the face of recently on wall or from the more real ball of the ball of tennis serve machine.

Be understandable that, the sportsman of different heights has different batting demands.As mentioned above, bar 16 reaches the length of

substrate

12,58 tops and can regulate, and this conciliation can be used for adjusting exercising

device

10 or 54, to be fit to athletic height.
