The second embodiment is the table tennis returning plate of regulating panel angle with screw rod, sees Fig. 6, Fig. 7.

This example is basically identical with upper example, and the adjustment structure that is hinged pair changes, and all the other are all consistent with upper example.

The ring dish of tabular transverse arm 27 alternative 1 of two isosceles triangles, its triangle base be in the same position of example 1 grillage, and fixedly links as the trailing flank middle part of grillage 2 with the fluting cylinder; The contiguous position that is shaped with through hole is down on the top of column, and transverse arm triangle angle position is shaped with the minor axis that stretches out to its inboard, and minor axis becomes hinged secondary 9 to link with column 13 top through holes, is shaped with nut shim at the inboard axle head of column, deviates from outside the restriction short axial.The crossbeam at column middle part is positioned at panel lower edge corresponding site, and disconnect from the middle part, respectively be in sustained height, be positioned at rear, plane, column place, fixedly link with parallel plane ring frame both sides, two column places, be the horizontal bow member that slightly rearward stretches out, become this routine back rest 28.Lay the link stopper substantially coplanar with encircling frame 29 in the ring frame.The position that ring frame and both sides bow member link links with the trunnion axis that is stretched out by the block both sides is hinged, the through hole that be shaped with axis vertical-horizontal hinge axes and link stopper plane in the middle part of the block, can cooperate with screw rod.Screw rod 24 diameters are suitable with through-hole aperture, and after screw rod penetrated the block through hole, the screw portion suitable with lead to the hole site was shaped with screw thread, are equipped with respectively the adjusting nut 23 that cooperates with screw rod at block through hole two ends.Screw front end is shaped with hinged the linking of two ears of pin 25 with the bearing 26 of axis horizontal, vertical screw axis, and bearing is fixed on the middle part of panel lower edge trailing flank.The main contents that more than are different from upper routine structure for this example.

During adjusting, because the transverse arm hinge axes is positioned at the rear side of panel, it is the state of acute angle that the panel deadweight can make panel remain on table, move block front and back two nuts to revolving away from the panel direction this moment, distance between nut and the panel is increased, through between two nuts, with the link position-limiting action of block front surface of the back rest, can increase the length of block the place ahead screw rod, can promote the angle that the panel lower edge swung forward, increased panel and table; Otherwise, move nut to revolving near the panel direction, equally owing to the position-limiting action of block rear surface, can reduce the length of block the place ahead screw rod, the panel lower edge is swung backward, reduce the angle of panel and table.More than be the adjustment structure of counter plate use angle and the description of operating process thereof, other situation and the upper example of this example are consistent.

The 3rd embodiment is the table tennis returning plate of regulating the panel use angle with worm couple, sees Fig. 8.

This example is consistent with above embodiment, and just the governor motion of panel use angle is changed into worm couple.

Transverse arm and the grillage of this example two worm gear 35 alternative, 1 ring dishes or example 2 link, and namely worm-wheel shaft is respectively from the two columns outsides, and also the through hole with the column middle part links, and become hinged secondary 9, and the axial location that limits worm gear by shaft end nut and the pad of column inboard.Worm gear is made large semi-circular, and its string limit fixedly links with the same routine relevant position with fluting cylinder grillage rear side middle part, only is shaped with the gear teeth in worm gear downside edge.At the corresponding site of column worm gear lower edge, fixing cooperate with worm-drive, with column with the coaxial hinged worm screw that links 36 of worm axis.When needs were regulated the use angle of panel, different worm screw rotation directions can obtain the rotation of worm gear different directions, drove grillage and panel, realized the adjusting to use angle.Because Worm Wheel System belongs to irreversible rotation, the use location after regulating can not change to some extent owing to panel weight adds to the moment of torsion of worm gear string avris, can guarantee instructions for use.

This routine compact conformation, adjusting facility are used reliable.

The 4th embodiment realizes the table tennis returning plate that panel promotes with the elevator structure, sees Fig. 1 and Fig. 2.

The structure that this is routine and above embodiment are basically identical, and just its panel is laid the transmission mechanism that the elevator pattern has been used in lifting highly.This example and grillage fixedly link, hinged what link can be ring dish described above, transverse arm or worm gear with column, but the position of connection all is positioned at the inner edge side of grillage rear side, and namely the outside of grillage trailing flank point of attachment still has vacant part.Be shaped with coaxial through-hole with the hinged minor axis centre that links of column, and with the hinged major axis 18 that cooperates, runs through two minor axises that have been installed on two columns of this through hole.Be positioned at the corresponding site of ring dish, transverse arm or worm gear outer face at major axis, be shaped with shoulder and continue the outwardly directed section of stretching out.This moment catch 4 or in addition the system position of being fixed in the corresponding section of stretching out of catch on transverse arm or the worm gear leave the through hole that limits shoulder, only allows the section of stretching out to stretch out.The major axis two ends exceed the section of stretching out of ring dish, transverse arm or worm gear outer face, and making the cross section is the regular polygon that is connected to the minor axis through hole in equilateral triangle, square or the orthohexagonal etc.; Major axis stretches out the built on stilts remaining suitable shaft section diameter of part of Duan Yuhuan dish, transverse arm or worm gear outer panel, for corresponding axis is rectified polygonal inscribed circle diameter.

Major axis stretches out grillage segmentum laterale total length and vertical long axis axis, can endwisely slip, be slidingly matched with the rocking arm 10 of corresponding regular polygon axis hole; Rocking arm slip stomidium is long, and to stretch out the diameter segment length consistent with major axis, and the major axis two ends are shaped with the bolt catch that prevents that rocking arm from deviating from from axle head.The brachium of rocking arm is the distance of octuple between major axis and grillage trailing flank approximately, can screw out to the position of vertical rocker-arm length direction when the power end of rocking arm is shaped with work, can turn back, be placed in the handgrip of rocking arm end section when not working.

Major axis be positioned at two columns inboard, with the inboard adjacent segment of column, the long lever arm such as difference hinged two are as both arms wheel carrier 6, the another end of two lever arms wheel shaft two ends of guide wheel 7 respectively and between these two ends are hinged, and with guide wheel be supported in major axis the top, be posted by the corresponding site of panel back surfaces.For making guide wheel normally be posted by back side of panel with radian, be positioned at front side, lever arm upper end, the outside and protrude slightly forward.Major axis section between each wheel carrier both arms, an end of pulling rope 8 is fixedly connected respectively, the another end of rope from bottom to top, through separately guide wheel rear side, to guide wheel upper limb height, from back to front, more from up to down, walk around guide wheel, by extending downward the panel lower edge between guide wheel and the back side of panel, fixedly link with the panel lower edge; The both sides pulling rope is isometric, consistent with panel lower edge fixed position.

At two grillage trailing flanks, be equivalent to the power end rotation of rocking arm to two positions that contact with its top, be shaped with respectively two vertically, vertical grillage trailing flanks, the flat board that is fixedly connected with two grillage trailing flanks, two flat boards keep horizontal range and rocking arm end diameter consistent size to each other, as this routine draw-in groove 20.In the two grillages outside separately, the power end rotation that is equivalent to rocking arm is to each two extreme, as to be in contact with it positions up and down, is shaped with respectively that size and draw-in groove are 20 consistent, the T groove 1 of cross sectional shape such as T word.To be that the T body of T groove is done vertical with the grillage lateral surface, T word thickness direction be rocking arm when forwarding this position to length direction, the T word thickness of rocking arm fixedly link for the dried lower end of length, T body and the grillage of this direction and grillage coincidence line, the height that the T body is dried, be that T word top board is consistent with spacing and the rocking arm end section diameter of grillage lateral surface.It more than is the record about this routine hoisting mechanism dependency structure content.

During assembling, other region of interest is identical with above corresponding embodiment, namely at the ring dish, after transverse arm or worm gear minor axis separately penetrates the column through hole, transverse arm or worm gear minor axis are located by inner nut shim, also two wheel carriers that this routine guide wheel is housed should be placed respectively each column inboard, penetrate successively the minor axis hole with major axis, the through hole that wheel carrier lower end and major axis are hinged, pass from other side minor axis centre bore, with bolt catch retainer ring dish and major axis, or with the restriction of the catch on transverse arm or worm gear major axis, pulling rope one end at the major axis that circumferentially is fixed in the wheel carrier, is upwards crossed guide wheel through the guide wheel rear and fixed down to the panel lower edge.The socket joint socket is positioned at the rocking arm at major axis two ends, the spacer bolt that the major axis axle head of packing into prevents that rocking arm from being deviate from by axle head, and the rocking-turn rocking arm, places the rocking arm end in the T groove respective side to the height that needs through pulling rope tension panel.So far finish the assembling process of this routine elevator structure, equipment is for treating duty.

When needs are regulated the height of panel, both sides rocking arm end is taken out in the T groove, the axle head direction shifts out vertically, exceed the corresponding axial location of T groove after, both sides are rotating arm simultaneously, rolls or emit pulling rope, can change the relative position of panel in the grillage groove.Because the long-range radius greater than major axis of rocker arm, so can use power much smaller than panel weight, slowly change the height and position of panel through pulling rope, for adjusting brings convenience.To be regulated when complete, move inward rocking arm to T groove respective inside, regain handgrip, make the rocking arm end enter contiguous T groove.Panel gravity acts on the moment of torsion of rocking arm reverse rotation through rope for traction, major axis, stopped by the T groove, makes the height and position after the adjusting of panel be maintained fixing.

If an attemperator is only arranged, in the time of maybe can only being positioned at the side adjusting of return of serve plate, can first the rocking arm that is positioned at offside T groove be taken out, inwardly move within the top draw-in groove 20 of grillage rear side, make at this moment rocking arm be in the cylindrical section of the major axis section of stretching out, connecting relation circumferential between this rocking arm and the major axis namely is disengaged; Because in addition to be the post of on-circular cross-section connect with socket joint between the hole side major axis and the rocking arm place of linking, the rocking arm end is spacing by the T groove again, the weight that can bear panel, and panel is still kept original position.The attemperator returns this side plate frame, takes out in the desired direction rocking-turn of rocking arm in the T groove.At this moment monolateral rocking arm rotates through major axis, the pulling rope that twines or loosen both sides, the height and position of change panel in grillage.Afterwards, finish adjusting with being pushed into the corresponding axial location of T groove in the rocking arm, putting into the T groove that closes on.The in addition side rocking arm that is disengaged the circumferentially connecting relation can not affect the operating process that this side rocking arm is regulated; Height after panel is regulated can be connected and fixed through major axis, rope by the spacing rocking arm of this side T groove.Also can take out from draw-in groove removing the in addition side rocking arm that connects, be pulled outwardly again to the corresponding axial location of T groove, put into T groove one side channel that vicinity can stop that rocking arm rotates to the panel falling direction, with the weight of other side rocking arm shared panel.

Certainly, this example can also with upper example in latch or the adjustment structure of cushion block be used in conjunction with, use hoisting mechanism when namely changing height, keep its height with cushion block or latch after adjusting to the right place, to free panel weight at the load of non-adjustment state to pulling rope, rocking arm is put into draw-in groove or the T groove of grillage and is fixed.This routine structure lifting is laborsaving, and it is convenient to regulate.

More than for the different implementation examples of table tennis returning plate of the present invention.

The 14 embodiment is the using method example of table tennis returning plate, such as Figure 18-22.

1. regulate with the angle between the table tennis table table top with the surface of panel bounce-back part, conversion is in the face of the exercise item of this bounce-back part, is 85-87 when spending with table extremely with the angular adjustment of return of serve plate, can practise the positive and negative ball that pulls; Be transferred to when spending to 88-92, can practise the froehand-backhand attacking driving; When being adjusted to 93-95 and spending, can practise positive and negative hand slam-shot; Service when more than practising is that ball is thrown rear this side billiard table of directly getting to, and bounce-back rebounds to the opponent's court at user place to the plate of returning serve again, and continues routinely to return this side billiard table by the other side, continues exercise; This kind exercise also helps to improve the control ability of user to exerting oneself.

2. panel is placed this side table tennis table dead astern (seeing Figure 18), can practise hitting the road straight shot and (be about to ball from the midline of user's one side billiard table, get to the midline of panel one side billiard table), the conversion ball of straight line, oblique line, and the technology of move left and right footwork, such as technology such as sliding steps, leapfrog, cross steps, single steps.

3. panel is moved to billiard table left comer or right corner, the normal direction of this place's panel and the diagonal of whole billiard table are consistent, can practise fore cross or back cross, and the fore cross of leaning to one side (seeing figure).

4. panel is placed the billiard table dead astern, Yi Bian it moves approximately 10 centimetres backward, can practise beating back straight and fore straight (seeing figure).

5. panel is advanced into above billiard table apart from about 30 centimeters of net, can practises positive and negative hand push ball, dial ball; Panel is advanced into above billiard table apart from about 10 centimeters of net, to the beginner can practise forehand, short ball (seeing figure) is chopped the chop, is put in backhand.Therefrom can improve ability of controlling the ball.This exercising method is that ball is directly got on the panel, and ball practitioner's side billiard table that rebounds is back got to ball on the panel after the bounce-back again, so repeats.

6. can improve sportsman's batting control and regulating power firmly with panel to white silk, because firmly excessive, can be from the end line out-of-bounds in sportsman one side stage district after the ball bounce-back, and firmly too small, ball then can not be backhauled by bounce-back mobilizes the side stage district, therefore, sportsman's's " number plate number " training method, can improve control and regulate ability firmly, more to the plate number of practicing with panel, control and the ability firmly of regulating are just stronger.

7. set objectives in the platform district of panel one side or articulate one or more small panel at panel, the sportsman can obviously improve the ability of hitting and the ability of controlling drop point by the training method of " beating target ".Can test hit rate with 10 tablees tennis, arbitrarily set up the position of target, and the size of target is decided according to technical merit, and comparable table tennis is large, and also comparable table tennis is little, or identical with table tennis.Hit the mark to get 1 minute; Miss the objective, the face if ball bounce-back returns to Chinese Taiwan then continue to beat if bounce-back is to sportsman's side stage district then lost 1 minute, can draw hit rate after 10 balls have been beaten.Hit rate reaches absolutely, can dwindle target, or target is placed the difficult position of beating, and generally places billiard table middle part ratio to be easier to hit, and places the billiard table both sides difficult; Can also carry out to different target the degree of accuracy exercise of continuous transformation.

8. panel is placed the billiard table dead astern, be an angle of 90 degrees with table, the sportsman stands in the middle of the offside billiard table, straight line various screws in road in sending out, as give and revolve " turn and do not turn " ball, on the left side, chop, on the right side, chop etc., the angle that can run into by ball the panel bounce-back, direction, speed is observed the revolution of basketball nature and extent, thereby improves constantly gyrating mass and the variation of service, as give to revolve to add and turn ball, the angle that ball is run into panel bounce-back downwards is little, speed is fast, and gives when revolving knuckle ball, and the angle of bounce-back is large, speed is slow, send out the left side spiral, ball is run into panel and is rebounded to left, and the top bounce-back is the left side topspin ball to the left, and the below bounce-back is the left side underspin ball to the left, right side spin is opposite direction in like manner.

During exercise the both sides net is set up, the ball that distributes can be collected, need not pick up ball, improve the efficient of exercise.Because panel is radian slightly, so this training method is best with road straight line screw effect in sending out, the angle that can reflect exactly bounce-back, and ball is dealt into the billiard table both sides, running into angle that panel rebounds back just reflects and to get not true and accurate, this mainly refers to send out the situation of left and right sides spiral, and backspin service is unaffected.After the requirement that reaches reverse twist service, just can stand in the screw that any position of billiard table sends out circuit any.Can also hang up linked network in the panel front, so that collect the table tennis that falls.

9. utilize the spacer screen on the panel, use the multi-ball drill method to practise various services, can by sportsman oneself with ball on billiard table, upspring by throwing rear self gravitation, by the sportsman ball is hit to again the billiard table at panel place.

10. panel and small panel are made multiple performance, elasticity, as want plate, long offset plate, anti-offset plate, positive offset plate, rubber plate etc., select to change for the user, different performance is placed on the panel of same use occasion, exercise is to the adaptive capacity of different ballistic properties.

11. the rule of the panel of different radians bounce-back is not identical with variation yet, comparatively mild panel return of serve circuit changes little, helps to train the athletic footwork of primary level, can carry out the specific aim exercise.
