Definitions

  • This invention relates to a goal structure for a game such as hockey which comprises a pair of goal posts interconnected by a cross bar at the upper end in which the posts are normally attached rigidly to the playing surface.
  • goal posts and goal structure are generally rigid and include projections or narrow struc­tures which can cause serious injury. This is overcome in hockey played by younger children by merely placing the rigid goal frame and net loosely on the playing sur­face so that whenever it is contacted by a player it simply moves away from the original location and no dam­age is caused.
  • the restraining force provided by this device is at a maximum before any displacement of the post occurs and then drops to zero once displacement has taken place.
  • the post is rigid and stationary without any deflection or displacement at the time of impact when injury is most likely.
  • a goal structure for attachment to an ice surface com­prising a pair of vertical goal posts each having a hol­low interior and arranged for attachment of a lower end thereof to the ice surface, a cross-bar rigidly inter­connecting said the goal posts at upper ends thereof in spaced upstanding position and a net support member extending rearwardly of and between the posts and rigidly attached to said lower ends thereof so that the goal structure defines a rigid body for supporting a net rear­wardly of a face defined between the goal posts which can sit on the ice surface upon a base defined by the lower ends of the posts and an underside of said net support member, and a kit of parts for attachment of the goal structure to the ice surface, said kit comprising first and second spring means for mounting within the hollow interior of respective ones of said posts, first attach­ment means for attaching one end of each of said spring means within said goal post to the goal structure and second attachment means for attaching an opposed end of each of said spring means to the ice surface through the other
  • a struc­ture of this type can provide the necessary flexibility, that is it can break away from the fixed position under severe impact and yet the goal structure itself is sub­stantially unchanged with the springs and coupling arrangements mounted substantially wholly within a post and therefore do not interfere in any way with the normal movement of the puck or projectile.
  • the spring force can be varied by providing different springs or an adjustment device and thus the impact force can be varied for different ages or sizes of player.
  • the hockey net or goal structure illustrated in Figure l is only one example since it will be appreciated that a goal structure of this type could be used in other games, but it is particularly useful for ice hockey where the velocity of movement of the players is very high and their stability reduced.
  • the goal structure is substantially the same as the conventional structure in that it comprises a pair of goal posts l0 and ll in the form of a hollow pipe which are integrally connected to a cross-bar l2 at the upper end which together form the goal face.
  • Rearwardly of the goal face is the net supporting structure which comprises rearwardly and inwardly extending net support l3 which lies against the playing surface and is rigidly attached to the goal posts at the bottom end.
  • a further upper support l4 is positioned at the top of the net and again is rigidly attached to the goal posts together with a downwardly and rearwardly extending strut l5 which con­nects to the centre of the bottom net support l3 to pro­vide a substantially rigid structure which does not col­lapse on impact and which can slide across the ice surface on the bottom of the posts and on the undersurface of the net support l3.
  • the details of the net support arrangements are arranged to conform to standard hockey nets and any rules which may apply.
  • a conventional con­struction of this type can either rest freely on the ice when young children are playing or alternatively, can be rigidly affixed to the ice by pins which extend upwardly from the ice attached to nuts secured to the concrete floor beneath the ice or in a more recent development, can be mounted on magnets in the ice playing surface.
  • the invention provides an improved mounting arrangement as will be described hereinafter.
  • the post l0 is formed from a hollow pipe with a cylindrical wall l6 upstanding from the ice surface indicated at l7.
  • the conventional existing anchor nut is illustrated at l8 mounted in the concrete floor l9.
  • the lower end of the post is closed by a guide block 20 which has a central axial aperture 2l.
  • a rigid anchor bolt 22 is provided which can screw into the nut l8 and includes a bore 23 for receiv­ing a nipple 24 of a flexible attachment cable 25.
  • the cable 25 is attached to one end of a spring 26 which comprises a coiled tension spring.
  • the other end of the spring 26 is attached to a transverse pin 27 which extends across the post l0 and has ends 28 and 29 which are received in slots 30 and 3l in the wall l6 of the post 10.
  • the shape of the slots 30 and 3l is shown in elevational view in Figure l and it will be noted that the slots are both of walking stick shape providing an elongate section 34 extending longitudinally of the post and at the upper end of the elongate section a notch 33.
  • the end portions 28 and 29 of the transverse pin 27 are reduced in width so as to enter relatively narrow slots 30 and 3l and the outer extent of the ends 28 and 29 is confined to lie within the outer peripheral surface of the wall l6 so as not to project beyond the outer edge of the post l0.
  • bores 34A are provided in the outer faces of the ends of the end por­tions 28 and 29 for receiving a tool by which the trans­verse pin 27 can be grasped for sliding in the slots 30 and 3l.
  • the transverse pin rests at the bottom of the elongate portion 34 of the slots 30 and 3l so that the top of the spring is displaced downwardly toward the bottom of the post l0, ll.
  • the flexible cable 25 is free to extend out through the guide block 20 without substantially tensioning the spring 26.
  • the post can be positioned in the ice with the cable 25 pulled to one side of the post for attachment to the bolt 22 which can then be screwed into position into the concrete floor.
  • the pin 27 is grasped by the tool (not shown) which engages the bores 34A and is lifted by the tool upwardly along the slots to the top of the elongate portion 34 at which the pin 27 is turned angularly as shown in Figure 3 by the arrow 35 so as to enter the notches 35 which act to re­ tain the pin 27 at the upper position of the slots 30, 3l.
  • the spring 26 is tensioned and any slack in the cable 25 is taken up so as to draw the post downwardly onto the pin 22.
  • the upper surface of the pin 22 is positioned at or below the level of the ice surface.
  • the underside of the guide block is smooth so that the post is free to slide sideways over the ice and is not in any way inhibited in its movement by contact with the pin. The sideways sliding movement thus tensions the spring 26 and flexes the cable 25.
  • the spring 26 and cable 25 act to draw the post back to its normal position with the projection 36 and recess 37 acting again to locate the post in the exact required position.
  • An inner surface of the block 20 at the bore 2l and an outer edge of the block 20 at the base of the post ll are both chamfered to avoid sharp edges which can cut the cable 25.
  • the screw coupling between the bolt 22 and the nut l8 can be replaced by a quick release coupling (not shown) so that the goal can be rapidly released to be removed for flooding the ice.
  • a separate cap can be provided to cover the nut when the goal is removed during flooding to prevent ice formation over the nut.
  • the post includes a guide block 4l at the lower end thereof which is formed from a plastics material and which is inserted into the lower end of the post with a flange 42 of the guide block acting to engage the lowermost end of the post and locate the guide block within the post.
  • Set screws 43 are provided to retain the guide block within the lower end.
  • a cable 44 passes through the guide block from an attachment nipple 45 at the lowermost end to an attachment member 46 at the upper end of the cable which can be clamped onto the cable by a set screw 47.
  • the attachment member 46 includes a male screw thread portion 48 which is screwed into fixed engagement with the inner surface of a spring 49.
  • the upper end of the spring 49 is similarly attached to an attachment member 50 which has a male screw thread 5l again screwed into the interior of the spring so as to allow the remainder of the spring to flex between the two attachment members.
  • the attachment member 50 has a central bore 52 which can rotate upon a pin 53 and is held in position on the pin by a washer and screw 54.
  • the pin 53 forms part of a elongated bar 55 which extends longitudinally and axially of the post 40.
  • the bar 55 has on an outside surface thereof a screw thread 56 which cooperates with an inner screw thread of an outer sleeve member 57 so that the axial position of the bar 55 can be adjusted by rotating the bar within the inner screw thread so as to increase and decrease the tension in the spring 49.
  • the rotation coupling between the attachment member 50 and the pin 53 allows the bar 55 to rotate in its adjustment movement.
  • Adjustment of the bar 55 is provided by a tool which can be inserted into an opening 58 in an upper end of the bar 55.
  • the opening comprises a cylindrical portion 59 and a counter bore portion 60 of increased diameter.
  • the counter bore por­tion 60 defines a bayonet type fitting so that a cross-­bar of a tool clan be inserted though a slot in the upper face into the bore 60 and can rotate around the bore 60 to engage a stop 6l so that further rotation of the tool causes the bar 55 to rotate and adjust axially.
  • the bayonet type fitting defined between the tool and the recess allows the bar 55 to be grasped by the tool and pulled axially.
  • the outer sleeve 57 is slideably positioned within an outermost sleeve 62 which is itself attached to the inner surface of the post by set screws 63.
  • a screw 64 projects inwardly from the inner surface of the outer­most sleeve 62 to engage into a slot 65 provided in the outer surface of the outer sleeve to prevent the outer sleeve from rotating as the bar 55 is rotated in its adjustment movement.
  • the cooperation between the slot 65 and the screw 64 limits the axial sliding movement of the outer sleeve so that it can move from the position shown in Figure 4 to a lowered position which will be apparent from inspection of the length of the slot 65 in which any tension in the spring is released and the cable 44 allowed to project without tension beyond the end of the guide block 4l to a length sufficient to allow the guide block and post to be moved to one side to expose the nipple 45.
  • a transversely slideable latch member 66 is supported in the outermost sleeve 62 so as to prevent axial movement of the latch member.
  • the latch member is however slideable across the sleeve and is biased to a latched position by a spring 7l so that a portion 67 thereof engages a recess in the outer sleeve 57 to prevent the sleeve from moving axially.
  • the portion 67 is formed as a circular bore so that movement sideways against the spring 7l of the latch member allows the circular outer sleeve 57 to drop through the bore indicated at 68 to the lowermost position.
  • Sideways movement of the latch 66 is obtained by pressure against an outer surface 69 thereof exposed at an opening 70 in the post.
  • the size of the opening 70 is small and is positioned inwardly and rear­wardly of the post so as not in any way to interfere with contact with the post of a puck or other projectiles.
  • the tool (not shown) which cooperates with the opening 58 at the end of the bar 55 can pass through a hole cut at the upper end of the post on the axis of the post as the post curves into the cross-bar. Again such a small opening does not interfere with the reaction between a puck and the goal structure.
  • a receptacle 7l which can be of a type which is permanently mounted in the concrete layer 72 or which is attached to the concrete layer by set screws applied from the top.
  • An inner sur­face of the receptacle includes projections 73 which can cooperate with a coupling member 74.
  • the coupling member 74 is formed in two parts split at a center line 75.
  • the coupling member includes an inner bore 76 an upper portion 77 of which tapers inwardly so as to cooperate with the nipple 45 to retain it in position within the coupling member 74.
  • the space between the two halves of the coup­ ling member indicated at 75 is sufficient so that when the tension is released on the nipple 45 and the nipple is moved downwardly into the wider part of the inner bore 76, one part of the coupling member can be moved inwardly to a position where it is free from the projection 73 and can thus be withdrawn out of the receptacle 7l.
  • the other half is also free to be with­drawn leaving the nipple 45 and the cable 44 totally free from the receptacle 7l so the post can be moved to one side.
  • the receptacle 7l is of the conventional type which includes an internal screw thread and the coupling member 74 has on the outer surface of each of the halves a cooperating screw thread so that when the two halves are forced out­wardly by the nipple 45 the screw thread on the outer surface cooperates with the inner screw of the receptacle to retain the two halves within the receptacle.
  • the upper surface of the receptacle 7l on the upper surface of the coupling member 74 are well below the upper surface of the ice as indi­cated at 78.
  • the under surface of the guide block 4l sits on the ice surface around the opening within which the receptacle is positioned.
  • the guide block is there­ fore free to slide sideways on the ice on impact on the post by a player providing sufficient force to overcome the resistance to movement generated by the spring and cable.
  • this post mounting arrangement provides immediate and soft deflec­tion of the post when impacted following which the force gradually increases while the speed of the impacting player slows.
  • This arrangement does therefore provide a very effective cushioning effect to reduce the danger of any injuries while allowing the post to be retained effec­tively in position and to spring back immediately to the required position without significantly interfering with the game.
