[specific embodiment]

To the embodiment 1 of the utility model ball return shown in Figure 3, ball return comprises framework 1, support 2 and double-deck bounce-back net at Fig. 1.As depicted in figs. 1 and 2, framework 1 and support 2 are connected by bolt.Double-deck bounce-back net is 2 layers of graticule mesh of pressing close to mutually 3.Anterior layer graticule mesh mesh width approximates 5/8ths of bulb diameter, and back layer graticule mesh is identical with anterior layer graticule mesh specification.2 layers of graticule mesh opened and is set up in the framework.The periphery of double-deck graticule mesh 3 is connected with elastic device with framework, by described elastic device graticule mesh is tightened.As shown in Figure 3, the periphery of double-deck graticule mesh 3 is connected with the tensioning frame by elastic threads 4, and elastic threads 4 is passed the mesh of described double-deck graticule mesh 3 peripheries, is wrapped on the hanging ring 1d that is welded on the framework, by elastic threads 4 double-deck graticule mesh 3 is tightened.

The bounce-back net of present embodiment ball return is made up of the near graticule mesh 3 of 2 laminatings, though internal layer graticule mesh mesh width equals outer graticule mesh mesh width, but when 2 layers of graticule mesh when tightening, the grid of front and back graticule mesh all unavoidably can take place some the distortion, the nettle of front and back graticule mesh can stagger mutually.Concerning each grid of anterior layer net, the distance that back layer grid staggers can be not identical.As shown in Figure 5,, not only can hit the nettle 301,302 of anterior layer graticule mesh, also can hit the back layer

graticule mesh nettle

303 or 304 that is attached to this grid back when ball 10 hits bounce-back when online.The bounce of ball is their common counteractive results.Because concerning the grid of each anterior layer net, the distance that back layer grid staggers has nothing in common with each other.So ball hits on the grid of different anterior layer nets, the front and back two layers of mesh is also inequality to the resultant direction of ball reaction force, and does not have certain rules.Shown in Fig. 5 a, 5b, 5c, this ball return is concerning the sportsman bats each time, because each ball 10 hits is the grid of different anterior layer net, so angle of rebound does not have rule, the orientation of return of serve can't be pre-estimated, actual combat sensation and interest when having increased training have also been improved the effect of training.

Back layer graticule mesh is identical with anterior layer graticule mesh specification in the present embodiment, but also can adopt the back layer graticule mesh of different size, for example back layer graticule mesh mesh width can be slightly less than the anterior layer graticule mesh, in general, being not less than 1/2nd of anterior layer graticule mesh mesh width gets final product, if front and back layer graticule mesh mesh width difference is too big, the variation of batting angle of rebound will reduce.

In the embodiment 2 of Fig. 4 and the utility model ball return shown in Figure 6, embodiment 2 comprises also that on the basis of embodiment 11 near graticule mesh 3 of individual layer bounce-

back net

5,2 laminatings is installed on an end face of described framework 1.Individual layer bounce-back net 5 is installed on the other end of framework 1, and both do not contact mutually.When the person of practising a ball game wishes to use traditional ball return, can allow individual layer bounce-back net 5 forward framework 1 upset, double-deck bounce-back net is backwards.The angle of the return of serve of ball return bounce-back at this moment is a direction substantially, does not have big variation.

In order to improve the portability of ball return, to shown in Figure 9, framework 1 is by 2 ㄇ

shape framework

1a and 1b is hinged combines as Fig. 7, and pin joint 1e is positioned at the position of 2 ㄇ shape frameworks, 1 butt joint, departs from plane, graticule mesh 3 place.Like this, after framework 1 opens,, can not draw in automatically because the tension force that graticule mesh 3 is tightened withstands on together the interface of framework 1 firmly.After framework 1 drew in, elastic threads 4 was closed up 2 ㄇ

shape framework

1a and 1b, can not open automatically.Like this, the volume of maximum component framework 1 can dwindle widely in the ball return.Simultaneously, as shown in Figure 9, ball return support 2 adopts dismountable combining structure, can dismantle apace and make up, and in the packing box of packing into after the whole ball return dismounting, the boot of the automobile of can packing into easily improves the portable performance of ball return greatly.
