Abstract

It is used to train and the light hollow curved of skill improvement bounce-back plate and preparation method invention describes a kind of ball such as football, vollyball, tennis and the beginner of table tennis motion.The hollow bounce-back plate erect touches sphere（Front）It is to have the arcwall face for gathering rebound effect, can be by that can realize that curved surface is faced upward or had a down dip certain angle in front and rear pin cushioning certain thickness, to adapt to different types of ball, plate also rebound with going out ball people distance and going out the difference of ball people's height, reach reduce juggle or bat difficulty, reduce pick up the ball time, improve the unit interval tactile ball number purpose, be advantageous to beginner etc. rapidly lifted the feel of the ball.

Description

A kind of hollow curved face type bounce-back plate and preparation method

Technical field

The present invention relates to ball such as football, vollyball, tennis and the beginner of table tennis motion to be used for training and technical ability The removable lightweight bounce-back plate of lifting.

Background technology

With people's sports, the popularization of especially various ball game, requirement to training facilities also more and more higher, But there was only sports ground at present, without the infrastructure for lifting feel of the ball playing skill enough.The feel of the ball of most students in middle and primary schools green hand is too poor, It also is difficult to produce confidence into court, can loses interest gradually certainly, so forms training less, playing skill is poor, and self-confidence is poor, interest Difference, then few vicious circle of playing football, therefore one kind is provided and is available for stadiums indoor and outdoor to use and feel of the ball ball can be lifted rapidly The training facilities of skill is extremely urgent.

The content of the invention

The present invention is intended to provide a kind of balls sport training plate of curved, at the same can adjustment angle up or down, Reach reduce juggle difficulty, reduce pick up the ball time, improve the unit interval tactile ball number target, so as to lifted juggle training effect Rate.

To achieve these goals, the invention provides a kind of hollow bounce-back plate of curved of lightweight and preparation side Method, the curved surface of the curved slab can be made into ellipse arc, the ball that goes out for the diverging that ball people hits is gathered bounce-back by curved surface and is returned to Go out ball people, continuously juggle or cry the difficulty of batting so as to substantially reduce sportsman to wall or plate, reduction is picked up ball time accounting, had The feel of the ball is lifted rapidly beneficial to beginner.

The bounce-back plate erect above is by that can realize in the certain thickness foot pad of front and rear pin cushioning or support and face upward or have a down dip Certain angle, different types of ball is so adapted to, also accommodates bounce-back plate and go out ball people distance and go out ball people's height Difference.

Such as Fig. 1 and Fig. 2, hollow curved surface bounce-back plate positive and negative（Touch sphere）It is the curved surface of arc, two side panels are all Flat board, each flat board tightly touch the central part of the curved edges of two tactile balls, and such two flat board can play limitation and touch sphere The effect of flexural deformation, and it is firm in flat board and the junction screw-driving of curved surface, guarantee.

Such as Fig. 1 and Fig. 5, between side is connected to curved slab former and later two panels with strip stiff sheet, two curved slabs are fixed, are prevented Big flexural deformation in use.

Such as Fig. 2 and Fig. 3, the flat board of side all seals the big half space of hollow curved slab, stickfast, so whole hollow song Panel can be used as container to load water, silt etc., can so prevent plate from being fallen down under being pushed away under bang or again.

Manufactured and completed by extruding-out process without the hollow curved bounce-back plate of side panel as described above.Such as Fig. 2 and Fig. 4, Can first by the destructing of the curved slab of unitary closed into two, mould is designed with half block curved surface plate shape, by extruder for shaping, After the completion of two halves curved slab is merged into closed surface plate such as Fig. 2, gluing integral by melting, re-polishing is processed into light Sliding surface.

The type semienclosed curved slab of water can be filled as described above to manufacture completion by plastics sucking moulding technique, by curved surface plate shape The mould of plastics sucking moulding is designed, goes out only to stay the curved slab of a lateral opening with ABS composite plate plastics sucking mouldings, finally uses surface plate Sealing-in fixes whole plate and opens an aperture into totally enclosed bounce-back plate, then in upper side, can fill water or river sand enter with Increase the weight of overall curved slab, to resist the impact of big ball.

Specific embodiment 1.

Design the shape and size of semi-surface plate first, on the basis of 3.6m*2.6m ellipses, major axis in vertical direction, from Oval left hand edge, which is turned right, offsets 20cm, draws a vertical line, cuts out an elliptic arc, then the 1.05m above oval leftmost side marginal point Locate the horizontal line of picture one, the horizontal line is connected with the elliptic arc cut out with fillet, the radius 5cm of fillet, and lower end is ibid set with upper end Count into symmetrical.

In the vertical line of picture one at 3.0cm on the left of left side edge point, the vertical line and upper and lower side horizontal line crosspoint are should be half bent The docking point of panel.

Such as Fig. 4 on the basis of the semi-surface plate cross section of the shape and size of above-mentioned determination, design, extrusion molding is prepared Mould, cut with 40,30,50cm for length standard in extrusion, then two 40cm semi-surface plate splicing is integral, with identical Material binding agent is adhesively fixed.The shape of curved slab centre, such as Fig. 2 are cut into the thick PC plate materials of 5mm again, then sealing-in is in curved surface Plate centre, is fixed with screw, completes the preparation of this curved slab.

Specific embodiment 2.

The shape and size of semi-surface plate are equally designed first, and on the basis of 3.6m*2.6m ellipses, major axis is in vertical side To, turned right from oval left hand edge and offset 20cm, drawn a vertical line, cut out an elliptic arc, then above oval leftmost side marginal point The horizontal line of picture one at 1.05m, the horizontal line are connected with the elliptic arc cut out with fillet, the radius 5.0cm of fillet, lower end and upper end Ibid it is designed to symmetrical.

Such as Fig. 4 on the basis of the semi-surface plate cross section of the shape and size of above-mentioned determination, design, extrusion molding is prepared Mould, cut with 40,30,50cm for length standard in extrusion, then two 40cm semi-surface plate splicing is integral, with identical Material binding agent is adhesively fixed.The thick sheet materials of 4mm are cut into such as Fig. 3 lower side shapes again, the plate cut out sealed following big The curved slab of half portion, is cemented with adhesive, and the watertight effect in inner space of bottom can not be allowed by reaching.

Above-mentioned curved slab inserts river sand in, practises available for big ball such as football, vollyball and basketball etc..

Specific embodiment 3.

The inner mould of plastics sucking moulding is designed in the shape, goes out only to stay a side to open with ABS composite plate plastics sucking mouldings The curved slab of mouth, finally fixes whole plate with surface plate sealing-in and opens an aperture into totally enclosed bounce-back plate, then in upper side Water can be filled or river sand is entered to increase the weight of overall curved slab, to resist the impact of big ball.

Claims

A kind of plate 1. hollow type for own elasticity ball training rebounds, it is characterised in that the positive and negative for the plate that rebounds（Touch sphere） It is the curved surface of arc, two sides are all planes, and can directly be adhesively fixed positive and negative two curved surfaces.
