The prior art design that discloses such as GB 2140311 (Collings) has also disclosed sidepiece.But the sidepiece that such device has is only as the simple interpolation to the main protection net.Therefore such additive is restricted making additive can be attached to support frame but do not disturb on the height more than the ground of user's swing arm.Therefore, for the protection to the mistake batting is provided with such device, such framework must significantly be lifted on user's the height, has got rid of its situation about using under home environment basically.Simultaneously, the side plate of interpolation means that net can not provide with simple single-piece column structure, so production cost will be more expensive.

According to second embodiment, portable support comprises as Figure 10 a to 10d, the support shown in 11,12 and 13.Support 291 and comprise the attachment members 292 that supports from vertical substantially post 293, post 293 by foot member 294 from support.Support 291 and further comprise two arms of stability 295 that extend to the rear flank from the side of attachment members 292.Each arm of stability 295 also is equipped with foot member 294 to stand on the stayed surface.In the present embodiment, each foot member 294 all is basic semicircle so that roomy relatively plane base to be provided.The arm of stability 295 can be convenient to transportation from attachment members 292 dismountings.Attachment members 292 is suitable for supporting cup-shaped member 281, therefore applies a considerable amount of tension force to net, holds it in the mode that is stretched, and the roughly shape of loudspeaker is provided.Though have been found that the support that is significantly less than first embodiment according to the portable support weight of this design, but still can support net.This is because the arm 295 that extends to the rear flank distributes the weight of net to the rear of net end, still makes net keep clear clearly demarcated simultaneously.Like this, the weight of the weight of net and bracing or strutting arrangement matches the frictional force that is provided to stayed surface by the foot that supports has been provided.

Also have, in a second embodiment, the cup-shaped member 181 of first embodiment is substituted by the bigger admittance bowl-type element shown in Figure 14 and 15 281.Bowl-type element 281 comprises the shell 282 of leather, has foundation 283 and sidepiece 284.Net 112 is stitched to the inboard of sidepiece 284 to form the blind end of catch net.Leather is caught the inboard that wall 285 also is stitched to sidepiece 284.Wall terminal 286 is positioned at the rear portion of sidepiece 284 and catches wall 285 so that peripheral band 287 to be provided in order to support.Catch wall 285 then and fold back, admit bowl-type element 281 and the space 288 of catching between wall 285 and the shell 282 is provided thereby surround around peripheral band 287.The particle of the low screen resilience foamed material of the basic filling high density degree in this space.In addition, a plurality of holes 289 are arranged on air can be escaped when ball hits.The hole is covered by the reticulated on foundation 283 inner surfaces, prevents that foamed material from leaking.In use, when ball hits leather and catches wall 285, thereby wall 285 has the trend of compressed foam to the foamed material bias internal.Simultaneously air 288 is evicted from by hole 289 from the space, thereby brings into play function in the mode similar with impact absorption, disperses the energy from ball.Have been found that according to the admittance bowl-type element of present embodiment also effectively on the ball that stops even hit, can not produce any tangible rebound towards the rear by professional sportsman.Or rather, ball will fall into the bottom of catch net, gently be rolled near the basis of user's pin.This is to surpass the improvement that the main secure context of design is arranged earlier.

As the result who uses pliable and tough frame element 130, provide a kind of device of carrying out golf with the many remarkable advantages that surpass prior art.At first; provide to have very simple structure and can pass through the very upright catch net of simple steps the mode of taking catch net before pliable and tough frame element 130 and the sidepiece behind pliable and tough frame element 130 that the tension force of proper level is provided when catch net is upright.By using portable support 191, this device can clear surface only is provided but do not have other bracing or strutting arrangements such as the environment in gymnasium perhaps many families condition under assembling and using.By means of this design, height of devices can be restricted to the average height that is lower than the sportsman, and it can be used under many home environments easily.But the more important thing is, because the pliability of can be forward when ball hits net and getting back to the pliable and tough frame element 130 of its settling position to two side shiftings and elasticity, compare with the device with relative stiffness support frame, the whole energy absorption of this device strengthens greatly.Especially, by the use experience of the device of the embodiment of disclosure in WO 00/02629, the use rigid frame members causes causing the very fast damage to net, and especially strong batter square stance repeatedly is all the more so.On the contrary, use pliable and tough frame element 130, when ball hits net, make frame element and therefore the openend of net can be offset forward and to both sides, thereby allow net bigger skew significantly a little to be arranged being hit, net is reduced at the stress that is hit a little, as a result, the life-span significant prolongation of net.When net during, also obviously reduced the slight danger that ball penetrates net by overtime use.Yet because the elasticity of pliable and tough frame element 130, net is returned to its initial shape and prepares to accept next ball.Simultaneously, ball does not need the sportsman to take any special action just to turn back near the moving surface of sportsman's pin.In addition, this device is obviously light than the device of prior art, has identical characteristic and keeps identical intensity simultaneously.In addition; find with the cross correlation between basis and the pliable and tough frame element by careful design net; net with the simple circle rod structure just can form catch net; this catch net provides the openend with bottom and top; extend near the relief angle on basis below the basis bottom; top is from extending near going up most the point of pliable and tough frame element 130 in the mode of arc forward near the relief angle on basis; thereby provide the protectiveness sidepiece of encirclement to catch net, these sidepieces keep separating for the user inherently.Such net structure is simple production cost but also economy not only, and the catch net structure is provided simultaneously, and this catch net structure provides needed protection by the device of highly limited and free setting to the user, thereby is suitable for using under home environment.At last, provide a kind of ball holdout device by the admittance bowl-type element that uses second embodiment, this device is suitable for effectual whole kinetic energy of dispersing ball, prevents knock-on any degree to practical significance of ball.
