During assembling, grillage is positioned at the homonymy of two columns, ring dish minor axis is inserted in column through hole respectively outside two columns, with bolt, catch is fixed on outside column, in the screw of column ring groove position, load set bolt, insert panel from grillage slit opening upper end, in place in groove closed bottom end to its lower end, around ring dish minor axis rotary panel or grillage to required angle position, screw the bolt of ring disk ring groove place column.So far complete the assembling of table tennis returning plate, namely this routine table tennis returning plate enters treats duty.

If the working depth of panel is inadequate, panel can be promoted, select the respective through hole at the bottom of the grillage outer side slot of suitable panel lower edge position, insert latch and arrive at grillage lateral surface to its shoulder, groove lower end support panel can be substituted by latch from the upper side of the through hole section of stretching out, different lead to the hole site, panel can be made to be in different bearing heights, make panel keep corresponding suitable location, complete the adjustment that panel uses height.According to use needs, can trip ring disk ring groove place set bolt, rotary panel, change the position of its relative column, when panel is in the angle required for bounce-back ball, screw annular groove place, both sides bolt more respectively, ring dish and column are interfixed, completes the adjustment of panel use angle.

During use, roller can be provided convenience for the movement of whole return of serve plate, and return of serve plate is placed in the position required for relative billiard table, and can rebound corresponding ball, completes return of serve task.Relative position between adjustable ring dish and column, between panel and grillage groove, between whole table tennis returning plate and table tennis table, can distinguish or with its various combination, realize the adjustment of table tennis returning plate, to obtain different bounce-back return of serves; Change different ballistic properties, differently curved radian, even not level panel simultaneously, also can obtain different bounce-back return of serve abilities.

This routine support body provides basic ground supports; With slotted cylinder grillage by ring dish and the hinge-coupled relation that forms between support body, realize counter plate support fixing while, provide panel angle and the possibility highly regulated; The installation of catch both shaft orientation moving ranges of stop collar dish, do not hinder again the adjustment of erecting of panel angle; Socket joint between panel with grillage connects, also for the exchange of different performance panel is provided convenience; Roller gives the mobility of table tennis returning slab integral.

This example can also regulate panel to lay height by cushion block, sees Figure 4 and 5.

At this moment be no longer equipped with through hole in the side of grillage bottom land, but in the grillage groove of both sides lower end closed inner face on, set up equal height cushion block 21 respectively.When need regulate panel lay height time, can change or change superposition cushion block quantity or height, the bearing height of panel is changed, reach counter plate lay height adjustment.For the operating position of fixing cushion block, increase the cross section that cushion block protrudes grillage medial surface part, be fixedly connected with screw 22 and cell wall in the part increased.Like this, change the bearing height that cushion block can regulate panel, screw can fix the operating position of cushion block, and is convenient to operation when changing.Also can in cushion block additional magnet, keep the normal position of cushion block with the absorption affinity between itself and flute profile grillage, save with the fixing structure of screw.

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

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

The ring dish of two isosceles triangle tabular transverse arm 27 alternative 1, its triangle base, in the same position of example 1 grillage, is fixedly connected with as in the middle part of the trailing flank of grillage 2 with cylinder of slotting; The contiguous position being shaped with through hole is down on the top of column, and transverse arm vertex angle position is shaped with the minor axis stretched out inside it, and minor axis becomes hinged secondary 9 to be connected with column 13 top through hole, is shaped with nut shim at the inner side axle head of column, deviates from outside restriction short axial.Crossbeam in the middle part of column is positioned at panel lower edge corresponding site, and disconnect from middle part, respectively be in sustained height, be positioned at plane rear, column place, fixedly be connected with two parallel plane ring frame both sides, column place, be the horizontal bow member slightly rearward stretched out, become the back rest 28 of this example.The link stopper 29 substantially coplanar with ring frame is laid in ring frame.The position that ring frame and both sides bow member are connected, is connected with the trunnion axis stretched out by block both sides is hinged, the through hole that be shaped with the horizontally hinged axis of axes normal and link stopper plane in the middle part of block, can coordinate with screw rod.Screw rod 24 diameter is suitable with through-hole aperture, and after screw rod penetrates block through hole, the screw portion suitable with lead to the hole site is shaped with screw thread, is equipped with the adjusting nut 23 coordinated with screw rod at block through hole two ends respectively.Screw front end is shaped with axis horizontal, the pin 25 of vertical screw axis is connected with two ears of bearing 26 are hinged, and bearing is fixed on the middle part of panel lower edge trailing flank.More than for this example is different from the main contents of upper routine structure.

During adjustment, because transverse arm hinge axes is positioned at the rear side of panel, it is the state of acute angle that panel deadweight can make panel remain on table, now move two nuts before and after block to revolving away from panel direction, distance between nut and panel is increased, through the position-limiting action of the block front surface that is connected between two nuts, with the back rest, the length of block front screw rod can be increased, the angle that panel lower edge swings forward, increases panel and table can be promoted; Otherwise, moving nut to revolving near panel direction, equally due to the position-limiting action of block rear surface, the length of block front screw rod can be reduced, panel lower edge is swung backward, reducing the angle of panel and table.Be more than 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.

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

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

Transverse arm and the grillage of this example two worm gear 35 alternative 1 ring dish or example 2 are connected, and namely worm-wheel shaft is respectively outside two columns, also with column in the middle part of through hole be connected, become hinged secondary 9, and limited the axial location of worm gear by the shaft end nut inside column and pad.Large semi-circular made by worm gear, and its string limit is fixedly connected with the same routine relevant position at middle part on rear side of cylinder grillage of slotting, and only on the downside of worm gear, edge is shaped with the gear teeth.At the corresponding site of column worm gear lower edge, fixing to coordinate with worm-drive, with column with the coaxial hinged worm screw 36 be connected of worm axis.When needing the use angle regulating panel, different worm screw rotation directions, can obtain the rotation of worm gear different directions, drives grillage and panel, realizes the adjustment to use angle.Because Worm Wheel System belongs to irreversible rotation, the use location after regulating, can not change to some extent because panel weight adds to the moment of torsion of worm gear string avris, can ensure instructions for use.

This routine compact conformation, adjustment facility, use reliable.

4th embodiment is the table tennis returning plate realizing panel lifting with elevator structure, sees Fig. 1 and Fig. 2.

Structure and the above embodiment of this example are basically identical, and just the transmission mechanism that lifting highly employs elevator pattern laid by its panel.This example and grillage are fixedly connected, hinged what be connected can be ring dish described above, transverse arm or worm gear with column, but the position connected all is positioned at the inner edge side on rear side of grillage, and namely the outside of grillage trailing flank point of attachment still has vacant part.Coaxial through-hole is being shaped with the hinged minor axis centre be connected of column, and the major axis 18 that coordinate, run through two minor axises that are installed on two columns hinged with 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.Now the through hole limiting shoulder, only allow the section of stretching out to stretch out is left at catch 4 or another position of making the corresponding section of stretching out of catch be fixed on transverse arm or worm gear.Major axis two ends exceed the section of stretching out of ring dish, transverse arm or worm gear outer face, and making cross section is the regular polygon being connected to minor axis through hole in equilateral triangle, square or orthohexagonal etc.; Major axis stretches out Duan Yuhuan dish, transverse arm or worm gear outer panel and makes somebody a mere figurehead remaining part and divide suitable shaft section diameter, is the inscribed circle diameter of corresponding axle head regular polygon.

Major axis stretch out grillage segmentum laterale total length to vertical long axis axis, can slide axially, be slidably matched with the rocking arm 10 of corresponding regular polygon axis hole; It is consistent that rocking arm slip stomidium length and major axis stretch out diameter segment length, and major axis two ends are shaped with the bolt catch preventing rocking arm from deviating from from axle head.The brachium of rocking arm is about the distance of octuple between major axis and grillage trailing flank, can screw out when the power end of rocking arm is shaped with work to vertical rocker-arm length direction position, do not work time can to turn back, be placed on the hand handle of rocking arm end section.

To be positioned at inside two columns at major axis, with column inside adjacent segment, 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 guide wheel are supported in the top of major axis, are posted by the corresponding site of panel back surfaces.For making guide wheel normally be posted by back side of panel with radian, being positioned on front side of lever arm upper end, outside and protruding slightly forward.Major axis section between each wheel carrier both arms, be fixedly connected one end of pulling rope 8 respectively, the another end of rope from bottom to top, on rear side of respective guide wheel, to guide wheel upper limb height, from back to front, more from up to down, walk around guide wheel, by extending downward panel lower edge between guide wheel and back side of panel, be fixedly connected with panel lower edge; 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 with its upper contact, 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 consistent with rocking arm end diameters to each other, as the draw-in groove 20 of this example.In two grillages outside separately, the power end being equivalent to rocking arm rotates to each two extreme, to be in contact with it positions up and down, is respectively shaped with that size is consistent with draw-in groove 20, cross sectional shape is as the T groove 1 of T word.Namely the length that the T body of T groove does length direction that, T word thickness direction vertical with grillage lateral surface is rocking arm rocking arm when forwarding this position to, T word thickness is this direction and grillage coincidence line, T body does lower end and grillage is fixedly connected, and spacing and the rocking arm end section diameter of T body height, i.e. the T word top board done and grillage lateral surface are consistent.It is more than the description about this routine hoisting mechanism dependency structure content.

During assembling, other region of interest is identical with above corresponding embodiment, namely at ring dish, after transverse arm or worm gear minor axis separately penetrates column through hole, transverse arm or worm gear minor axis are located by inner nut shim, also should two wheel carriers that this routine guide wheel is housed be placed in inside each column respectively, minor axis hole is penetrated successively with major axis, wheel carrier lower end and the hinged through hole of major axis, from another side, minor axis centre bore passes, with bolt catch retainer ring dish and major axis, or limit major axis with the catch on transverse arm or worm gear, pulling rope one end is fixed on the major axis in wheel carrier in circumference, fix down to panel lower edge again up over guide wheel through guide wheel rear.Socket joint socket is positioned at the rocking arm at major axis two ends, loads the spacer bolt that major axis axle head prevents rocking arm from being deviate from by axle head, and rocking arm end, is placed in the corresponding side of T groove to the height needed through pulling rope tension panel by rocking-turn rocking arm.So far complete the assembling process of this routine elevator structure, equipment is for treating duty.

When needing the height regulating panel, taken out in T groove by both sides rocking arm end, axle head direction is shifted out vertically, and after exceeding the corresponding axial location of T groove, both sides are rotating arm simultaneously, rolls or releases pulling rope, can change the relative position of panel in grillage groove.Being greater than the radius of major axis because rocker arm is long-range, so by the power much smaller than panel weight, the height and position of panel slowly can be changed through pulling rope, bringing convenience for regulating.To be regulated complete time, move inward rocking arm to T groove respective inside, regain hand handle, make rocking arm end enter contiguous T groove.Panel gravity acts on through rope for traction, major axis the moment of torsion that rocking arm reversely rotates, stop by T groove, the height and position after the adjustment of panel is maintained fixing.

If only there is an attemperator, when maybe can only be positioned at the side adjustment of return of serve plate, first the rocking arm being positioned at offside T groove can be taken out, inwardly move within the top draw-in groove 20 on rear side of grillage, make rocking arm at this moment be in the cylindrical section of the major axis section of stretching out, between this rocking arm and major axis, namely the connecting relation of circumference is removed; Because another side major axis is that the post of on-circular cross-section connects with the socket joint between hole with the rocking arm place of being connected, rocking arm end is spacing by T groove again, and can bear the weight of panel, panel still maintains original position.Attemperator returns this side plate frame, takes out rocking arm rocking-turn in the desired direction in T groove.At this moment monolateral rocking arm rotates through major axis, the pulling rope being wound around or loosening both sides, the height and position of change panel in grillage.Afterwards, by being pushed into the corresponding axial location of T groove in rocking arm, putting into the T groove closed on and completing adjustment.The operating process of this side rocking arm adjustment can not be affected by the another side rocking arm removing circumferentially connecting relation; Height after panel regulates, can be connected and fixed through major axis, rope by the rocking arm that this side T groove is spacing.Also can take out removing the another side rocking arm connected from draw-in groove, then be pulled outwardly to the corresponding axial location of T groove, put into vicinity and can stop T groove one side channel that rocking arm rotates to panel falling direction, with the weight of another side rocking arm shared panel.

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

Be more than the different implementation examples of table tennis returning plate of the present invention.

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

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

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

3. panel is moved to billiard table left comer or right corner, the diagonal of the normal direction of this place's panel and whole billiard table is consistent, fore cross or back cross can be practised, and fore cross of leaning to one side (see Figure 20).

4. panel is placed in billiard table dead astern, it moves about 10 centimetres backward, can practise beating back straight and fore straight (see Figure 19).

5. panel is advanced into above billiard table apart from net about 30 centimeters, positive and negative hand push ball can be practised, dial ball; Panel is advanced into above billiard table apart from net about 10 centimeters, forehand can be practised to beginner, backhand is chopped the chop, put short ball (see Figure 20 and 21).Therefrom ability of controlling the ball can be improved.This exercising method is directly got on panel by ball, and ball rebounds back practitioner side billiard table, gets on panel again, so repeat after bounce-back by ball.

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

7. set objectives in the platform district of panel side or mount one or more small panel at panel, sportsman, by the training method of " beating target ", can significantly improve the ability of hit and control the ability of drop point.Can test hit rate with 10 tablees tennis, the position of target is arbitrarily set up, and the size of target is determined 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 obtain 1 point; Miss the objective, the face if ball bounce-back returns to Chinese Taiwan, continue to beat, if do not rebound sportsman's side stage district, lose 1 point, 10 balls can draw hit rate after having beaten.Hit rate reaches absolutely, can reduce target, or target is placed in the more difficult position beaten, generally be placed in billiard table middle part ratio and be easier to hit, and is placed in billiard table both sides difficult; The degree of accuracy exercise of continuous transformation can also be carried out to different target.

8. panel is placed in billiard table dead astern, be an angle of 90 degrees with table, player stands is in the middle of offside billiard table, send out the various screw of Road straight line, " turn and do not turn " ball is revolved as given, on left side, chop, on right side, chop etc., the angle of panel bounce-back is encountered by ball, direction, speed observes the rotation nature and extent of ball, thus improve constantly gyrating mass and the change of service, revolve to add as given and turn ball, it is little that the angle that panel rebounds encountered downwards by ball, speed is fast, and give when revolving knuckle ball, the angle of bounce-back is large, speed is slow, send out left side spiral, ball is encountered panel and is rebounded to the left, top bounce-back is left side topspin ball to the left, below bounce-back is left side underspin ball to the left, right side spin in like manner, just direction is contrary.

During exercise, both sides net is set up, the ball distributed can be collected, need not ball be picked up, improve the efficiency of exercise.Due to panel slightly radian, so this training method is best to send out Road straight line screw effect, the angle of bounce-back can be reflected exactly, and ball is dealt into billiard table both sides, encounter angle that panel rebounds back just to reflect and to obtain true and accurate not, this mainly refers to the situation sending out left and right sides spiral, and backspin service is unaffected.When after the requirement reaching reverse twist service, the screw that any position of billiard table sends out circuit any just can be stood in.Linked network can also be hung up, so that collect the table tennis fallen before panel.

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

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

The rule of the panel bounce-back of 11. different radians is not identical with change yet, and comparatively mild panel return of serve circuit change is little, contributes to the athletic footwork of training primary level, can carry out specific aim exercise.

The difference of 12. sizes can use by supporting varying mesa.Small-sized table tennis returning plate can shorten return of serve plate and be about the size of half, can mate with small-sized billiard table, contributes to developing athletes and to go back home middle exercise basic fundamental.

The elasticity of 13. panels and the content of exercise can be regulated with the distance that billiard table is laid, the user that strength is little can select elasticity large, lay pattern apart near, the user that strength is large can select that elasticity is less, distance exercise mode slightly far away, and is applicable to exercise and has an effect and draw accelerated loop, attacking driving and slam-shot.

14. exercises carrying out doubles transposition.In turn ball is beaten the target and direction of specifying to panel by two sportsmen, rebound also can get back to corresponding drop point regularly, makes sportsman practise the transposition footwork of rule; Impact target if do not specify, irregular two people within the scope of full court can be practised and to replace footwork.

Regulate the position of the relative table tennis table of panel, conversion exercise item mounts small panel in panel local, can carry out the exercise of accurate drop point.

In sum, using method has enriched the content of the single exercise of table tennis significantly.
