  • the apparatus may be erected on any suitable supporting surface such as reasonably flat ground or on the floor of a room. It is a further feature of the embodiments that the apparatus is free standing and requires no structural support such as being tied to pegs in the ground or to a support column other than the separate free standing net support described as part of some of the embodiments.
  • a first embodiment is shown in Figures 1 to 10 .
  • the apparatus of the first embodiment comprises an enclosure 111 for catching a ball (not shown) having a membrane in the form of a net 112 having an open end 113 and a closed end 114 thereby defining a space 115 into which a ball may be projected.
  • the net 112 is adapted to be supported at its open end 113 from a first self supporting structure 120 which comprises a base 121 and flexible resilient elongate frame element 130, as better shown in Figure 2 .
  • the base 121 of the structure 120 comprises a base frame in which there is located a playing surface 126, the base frame defined by side members 122 and 123, a rear member 124 and a front member 125.
  • the outline of the base is of substantially trapezoidal in form, having the two sides 122 and 123 converging from the rear to the front, as seen in the plan view.
  • the base is adapted to better cooperate with the net which is substantially conical in form when in use.
  • a portion of the net is laid beneath the base and it has been found that a converging base form sits over the net in a way that avoids bunching and/or stretching of the net in localised areas.
  • This configuration enables the net to be constructed by simple cylindrical netting thereby avoiding difficult and expensive net construction.
  • the net 113 is of cylindrical or tubular construction, a construction method well known to those skilled in the art, having an edge transverse to the cylinder axis at one end to comprise the closed end and an edge formed obliquely to the cylinder axis at the other end to provide the open end.
  • the net may be formed from any suitable material but netting of Rachell Knotless Knitted type has been found to be particularly suitable.
  • Nylon is the preferred cord material for forming the netting due to its strength and durability.
  • other, less expensive materials including polyester, polypropylene or polyethylene may also be used.
  • nylon is preferred due to its superior strength which therefore provides the least weight per unit of area of netting material. It is also more pliable which enables the net to adopt the desired enclosure shape more readily and with lower tension applied.
  • the netting mesh size is determined to be as large as practicable while still being capable of preventing the passage of the ball through the netting. The size selected will also depend upon the netting material chosen and its thickness.
  • a net produced from nylon of 3mm thickness with a mesh size of 16mm x 16mm is considered optimum to stop a golf ball, although these parameters may be modified depending on the circumstances.
  • the playing surface 126 is defined by a first group of three, identically shaped mats 127, each of symmetrical trapezoidal shape, and a second group of three, identically shaped mats 128 each of symmetrical trapezoidal shape.
  • the length of the non-parallel sides of the mats of the second group is the same as the length of the non-parallel sides of the first group, while the length of the shorter parallel side of mats of the second group is equal to the length of the longer side of the mats of the first group.
  • the mats are arranged on the supporting surface to provide the playing surface 126 in three columns of two mats side by side, each column being of symmetrical trapezoidal shape.
  • the playing surface thereby is provided with two straight sides and a front end comprising three, equal-length segments and a rear end comprising three, equal-length segments.
  • Each mat comprises a support base with an upper surface suitable for practising the striking of a golf ball with a golf club.
  • Synthetic lawn has been found to be very suitable although even good carpet has proved to be adequate for general practice. Indeed it is possible for the rear mats, only to be of a type suitable for striking the ball as a player would generally find he is too close to the net if he strikes from the forward mats.
  • the base frame when assembled, provides a border surrounding and abuttingly conforming to the assembled playing surface 126.
  • the side member 122 and 123, the front member 124 and the rear member 125 each comprise three sub-members.
  • the side member 122 comprises a central sub-member 131, a forward sub-member 132 and a rearward sub-member 133, while the side member 123 comprises a central sub-member 131, a forward sub-member 134 and a rearward sub-member 135.
  • each central sub-member 131 comprises an integrally moulded, substantially channelled-section member having an upper flange 135 joined to a lower flange 136 by a web 137.
  • the lower flange 136 is planar and adapted to sit on a flat surface, while the upper flange 135 is arcuate as seen from the side view.
  • the web 137 is inwardly indented at a position spaced from the upper and lower channel to provide additional stiffness.
  • the central sub-member 131 is provided with a lattice of reinforcing ribs 138 extending the length of the sub-member within the channel portion.
  • a laterally disposed tube portion 139 extending from the upper flange 135 to the lower flange 136, and attached to the web 137 for strength.
  • the tube portion 139 is aligned with an aperture 140 in the upper flange 135 and adapted to receive an end of the frame element 130.
  • each connecting means comprises a leg portion 141 extending from the respective end of the central sub-member 131 and terminating in a retaining head 142 overlying the leg portion 141.
  • Figures 5 a to f depict a sub-member suitable for use as sub-member 132 or 135. It should be understood that sub-members 133 and 134 are of the mirror image construction and are not separately described. The sub-members are generally of the same manner of construction as the central sub-member 131, having a substantially channel section with lattice reinforcement. At the end of each of the sub-members adjoining the central sub-member 131 there is provided female engaging means in the form of two apertures 143, each shaped with a profile corresponding with the outline of the male connecting means of the central sub-member 131 and adapted to engagingly receive the respective male connecting means.
  • each of the sub-members remote from the central sub-member 131 there is provided connecting means in the form of a single male member 142 of corresponding design to those provided on the central sub-member when viewed from the side elevation as shown in Figure 5a .
  • Each upper flange of the forward and rearward sub-members is arcuate when viewed from the side elevation as shown in Figure 5a . Due to the arcuate profile of the upper flange of the forward and rearward sub-members, the height of the side members reduces towards the end remote from the central sub-member 131.
  • the front member 124 comprises a middle sub-member 151, a left sub-member 152 and a right sub-member 153.
  • Figures 6 a to g depict the middle sub-member 151.
  • Each sub-member comprises a moulding from plastics material having a regular upper surface 161 extending from a transverse lip 162 at the inner edge to the outer edge.
  • the inner edge of each sub-member has a height corresponding with the thickness of the mats of the playing surface.
  • the profile of the upper surface 161 is arcuate so that, when the sub-member is placed on a planar surface for use, the upper surface extends substantially to the planar surface at the outer edge.
  • the upper surface 161 is reinforced by a lattice of ribs 164 substantially transverse to the upper surface extending to the plane bounded by the lower edges of the sub-member.
  • Corresponding connection means are provided at the ends of each sub-member for connection with the adjoining sub-member.
  • the left and right sub-members 152 and 153 have connection means suitable for connecting with a corresponding forward side sub-member 132 or 134 respectively on their ends remote from the middle sub-member 151.
  • the rear member 125 comprises a middle sub-member 171, a left sub-member and a right sub-member.
  • the middle sub-member 171 is shown in Figures 7 a to g.
  • the manner of construction of the sub-members of the rearward member 125 is similar to that of the forward member, the profile of bottom surface incorporating a space 173 in order to accommodate the net 112 as discussed below.
  • the rearward sub-members include identification markings 175 on the upper surface.
  • the flexible frame element 130 is adapted to be supported from the sides of the base to form an arch able to support the open end of the net 112.
  • the flexible frame element 130 comprises a rod or tube of substantial strength in order to be able to support the net 112 and may be formed from fibreglass or suitable plastics material such as a medium to high-density polyethylene to provide the relevant level of resilient flexibility.
  • the ends of the flexible frame element 130 are received within the tube portion 139 of each side member through each aperture 140.
  • the exposed portions of the flexible frame element are covered by an energy absorbing material such as a foamed plastics material.
  • the net 112 is of drooping conical or horn-like configuration when in use, the horn-like shape extending from the closed end to the open end to direct a ball to roll from the closed end to the playing surface.
  • the closed end 114 is created by circumferentially binding the net 112 adjacent the closed end 114 about an end element in the form of a cup 181.
  • the cup 181 is preferably made from leather as this material has been found to provide the required strength and durability together with the appropriate impact absorbing properties to absorb the energy of a ball in the event of a direct hit.
  • the use of the cup 181 also prevents a ball from becoming jammed at the closed end 114 and reduces wear at that area of the net 112.
  • the cup 181 comprises retaining means 182 adapted to be engaged by suitable supporting means.
  • the cup 181 also incorporates a resilient pad 183 covering the base 185 of the cup 181.
  • the pad 183 is adapted to further absorb the energy of a ball in the event of a direct hit.
  • the base 185 of the cup 181 is mounted obliquely to the horizontal so that a direct hit is not reflected straight back to the player.
  • the closed end is supported above the supporting surface by suitable support means to hold the net 112 in extended form. While it may be possible to support the closed end from a neighbouring fixed structure such as a wall or a post extending from the supporting surface or by a support structure extending from the base, as disclosed in the applicant's previous disclosure, WO 00/02629 , it has been found advantageous to provide a portable support 191 to enable the enclosure to be utilised on any supporting surface even where no suitable fixed structure is available.
  • the portable support 191 comprises a portable base member 192 and a resilient elongate support member 197 having a small degree of flexibility.
  • the portable base member 192 comprises a substantially hollow, closed container having a sealable opening 193 and of substantially pyramid form having a relatively broad foot 194 and a means for supporting the elongate support member 197.
  • this means for supporting comprises a recess 195 in the wall of the container adapted to receive and hold the end of the elongate support member 197.
  • the elongate support member 197 may simply comprise a relatively strong rod or tube of wood or plastics material but is preferably a mechanism of adjustable length.
  • the elongate support member 197 is placed within the recess 195, the portable base member 192 is filled with water through the sealable opening which is then sealed by a suitable cap.
  • the portable base member 192 when filled with water provides a free-standing, stable support capable of supporting the net.
  • the limited flexibility of the elongate support member 197 enables the member to deflect when a ball strikes the net, thereby absorbing a portion of the impact.
  • the open end 113 of the net 112 is provided with a tensioning strip in the form of a hem 116.
  • the open end 113 comprises a lower portion and an upper portion.
  • the lower portion is adapted to have the base 121 at least partially overlie the lower portion and be secured by hooks or other retaining means adjacent the rear corners of the base.
  • the base surface of the rear member 125 incorporates a space 173 adapted to accommodate the tensioning strip of the lower portion of the open end 113.
  • the upper portion is adapted to extend above the base from adjacent the rear corners of the base to the flexible frame element 130 substantially above the base, thereby providing side portions of the net adapted to intercept the ball in the event that the ball is mis-hit by the player.
  • the hem 116 of the central section of the upper portion of the open end 113 is adapted to receive the frame element 130 through apertures in the hem 116.
  • the portable support comprises a support as shown in Figures 10a to 10d , 11 , 12 and 13 .
  • the support 291 comprises an attachment member 292 supported from a substantially vertical post 293 supported from the supporting surface by a foot member 294.
  • the support 291 further comprises two stabilizing arms 295 extending sidewardly and rearwardly from the sides of the attachment member 292.
  • Each stabilizing arm 295 is also provided with a foot member 294 to rest on the supporting surface.
  • each foot member 295 is of substantially hemispherical shape to provide a relatively broad flat base.
  • the stabilizing arms 295 are detachable from the attachment member 292 to facilitate transportation.
  • the attachment member 292 is adapted to support the cup 281 and thereby apply a significant tension to the net to hold it in an extended manner to provide the substantially horn-like shape. It has been found that a portable support in accordance with this design is able to support the net while weighing considerably less than the support of the first embodiment. This is because the sidewardly and rearwardly extending arms 295 distribute the weight of the net rearwardly of the end of the net, while still being clear of the net. In this way the weight of the net cooperates with the weight of the support means to increase the frictional force provided by the feet of the support to the support surface.
  • the cup 181 of the first embodiment is replaced by a larger receiving bowl 281, as shown in Figures 14 and 15 .
  • the bowl 281 comprises an external shell 282 of leather having a base portion 283 and a side portion 284.
  • the net 113 is sewn to the inner side of the side portion 284 to form the closed end of the enclosure.
  • a leather catching wall 285 is also sewn to the inner side of the side portion 284.
  • the wall extremity 286 is positioned to rear of the side portion 284 to provide a circumferential strip 287 to support the catching wall 285.
  • the catching wall 285 is then folded backwards about the circumferential strip 287 to thereby enclose the receiving bowl 281 and provide a space 288 between the catching wall 285 and the external shell 282.
  • This space is substantially filled with pellets of high-density, low-recoil foam.
  • a plurality of apertures 289 are provided in the base portion 283 to enable air to escape upon the impact of a ball.
  • the apertures are covered by netting on the inner surface of the base portion 283 to prevent escape of the foam. In use, when a ball strikes the leather catching wall 285, the wall 285 is deflected into the foam and tends to thereby compress it.
  • an apparatus for practising ball sports which has a number of significant advantages over those of the prior art.
  • an enclosure which has a very simple design and which is capable of being erected by a very simple procedure, in a way that provides the appropriate level of tension to the enclosure forward of the flexible frame element 130 and to the side portions to the rear of the flexible frame element 130.
  • the apparatus may be assembled and used in environments which only provide a clear surface and no other means of support, such as a sports hall or many domestic situations.
  • the height of the device may be limited to less that of an average player, such that it can readily be used in many domestic environments.
  • the use of the flexible frame element 130 enables the frame element and thus the open end of the net to be deflected forwardly and sidewardly when a ball strikes the net, thereby permitting considerably greater deflection of the net at the point of impact so that the stress on the net at the point of impact is reduced and as a result, the life of the net is prolonged considerably. This also reduces considerably the slight risk of the ball penetrating the net when the net has been used extensively. Nevertheless, due to the resilience of the flexible frame element 130, the net is returned to its original shape ready to receive the next ball. At the same time, the ball is returned to the playing surface adjacent to the feet of the player without requiring the player to take any special action.
  • the apparatus is considerably lighter than prior art devices which have equivalent characteristics while retaining equivalent strength.
  • the enclosure by careful design of the interrelationship between the net, the base and the flexible frame element, it has been found possible to form the enclosure from a net of simple cylindrical construction which provides the open end with a lower portion extending from adjacent the rear corners of the base beneath the base and an upper portion which extends from adjacent the rear corners of the base forwardly in an arced arrangement to adjacent the uppermost point of the flexible frame element 130, thereby providing enveloping protective side portions to the enclosure which are inherently kept clear of the user.
  • Such net construction is therefore simple and economical to produce while providing an enclosure configuration that provides the user with the required protection by an apparatus of limited height and which is free-standing, thereby being adapted for use in domestic environments.
  • a ball stop which is adapted to dissipate practically all kinetic energy of the ball and prevent it from rebounding to any significant extent.
