Definitions

  • THIS INVENTION relates to an apparatus for generating a surface wave.
  • the invention has been devised particularly, although not solely, for generating a surface wave in a rink or other area used for sports, games or recreational activities particularly related to roller skating and skate boarding.
  • the present invention seeks to provide an apparatus for generating a surface wave which does not suffer from the disadvantage discussed above in relation to the prior proposals.
  • the invention resides in apparatus for generating a surface wave comprising a support surface, a flexible deck resting on the support surface, the flexible deck being constructed with a lateral deformation which provides a permanent wave formation in the deck, and means for moving the wave formation relative to the flexible deck.
  • the lateral deformation in the flexible deck is created by the presence of surplus material in the deck.
  • the deck is generally circular and the lateral deformation is created by introducing an additional sector of material into the circular deck.
  • the wave formation would progressively increase in amplitude in a radially outward direction from the centre of the deck.
  • the wave is arranged to move in a circuit around the flexible deck.
  • the support surface comprises a floor area or ground surface.
  • said means for moving the wave along the flexible deck comprises a carriage located between the support surface and the lateral deformation in the flexible deck. Movement of the carriage along the support surface causes movement of the wave formation along the flexible deck. While the carriage may cause the lateral deformation to assume a shape which provides a smooth wave formation, it does not in itself create the lateral deformation. The lateral deformation exists in the flexible deck irrespective of the presence of the carriage; the primary purpose of the carriage is to cause the wave formation to move relative to the flexible deck.
  • the carriage is preferably in the form of a boom disposed radially with respect to the flexible deck.
  • the boom may be supported on wheels which travel along the support surface, with at least one of the wheels being driven.
  • the boom preferably includes rollers which make rolling contact with the underside of the flexible deck.
  • the boom preferably extends upwardly in a radially outward direction to provide the varying amplitude of the wave formation.
  • the peripheral edge of the flexible deck is located closely adjacent the support surface when it is not elevated owing to the presence of the wave formation.
  • the peripheral edge of the support surface may be bevelled or otherwise shaped to define a ramp to provide a smooth transition between the support surface and the upper face of the deck.
  • the peripheral edge of the flexible deck is preferably constructed to provide cushioning upon impact. This serves to lessen the likelihood of damage or injury in the event of a rider crashing into the edge of the flexible deck when it is elevated owing to the presence of the wave formation.
  • a skirt or other protective device is preferably provided at the outer edge of the carriage.
  • the flexible deck may be of any suitable form, it is particularly convenient to construct the deck from . sectors.
  • the sectors may be sheet metal interconnected for limited pivotal movement at their neighbouring edges. The limited pivotal movement between sectors provides the deck with the required flexibility while preventing the wave formation from collapsing.
  • the flexible deck may be of laminated construction, with each lamination comprising a plurality of sectors. The sectors defining each lamination are bonded to sectors in a neighbouring lamination and are offset with respect to each other such that each sector in one lamination extends across two sectors of a neighbouring lamination.
  • the sectors may be of resilient sheet metal or any other suitable material.
  • Another form of the flexible deck may involve construction (by moulding or any other process) of a one-piece deck with the deformation created in it during the construction stage.
  • a moulding process is used to construct such a form of flexible deck, the mould would have a surface profile which would establish the deformation in the moulded deck.
  • the flexible deck may be provided with more than one wave formation if so desired.

  • the first embodiment is shown in Figs. 1 to 15 of the drawings and is directed to a rink for skateboarding and roller skating.
  • the rink includes a floor area 11 and a flexible deck 13 which rests on the floor.
  • the flexible deck 13 provides a surface over which riders of skateboards and roller skates can travel.
  • the peripheral edge 15 of the flexible deck is shaped to provide a ramp which provides a relatively smooth transition between the floor 11 and the upper surface of the flexible deck.
  • the flexible deck 13 is constructed with two diametrally opposed lateral deformations which provide permanent wave formations 17 in the deck.
  • the wave formations are created by the presence of surplus material in the deck, as will be explained in more detail later.
  • the wave formations remain in the flexible deck as it rests on the floor area and each can support its own weight and the normal weight of users on the rink.
  • a carriage 19 is located between the floor surface and each lateral deformation in the flexible deck. Movement of the carriages 19 over the floor surface 11 causes the wave formations 17 to travel in a circuit around the flexible deck.
  • the carriages 19 are coupled together for movement in unison and each comprises a mobile boom 21 disposed radially with respect to the circular flexible deck.
  • Each boom 21 is pivotally connected at its radially inner end to a beam 23 which is pivotally mounted onto a post 24 for rotation about a substantially vertical axis.
  • the boom 21 is supported on ground engaging wheels 25 at leat one of which is driven by drive means 20 such as an electric motor.
  • the boom 21 supports a plurality of rollers 27 for rolling contact with the underside of the flexible deck 13.
  • the rollers 27 are arranged to follow the progressively increasing amplitude of the wave formation in the radial direction.
  • the rollers 27 include central rollers 27a which contact the underside of the flexible deck at the crest of the wave formation and rollers 27b which contact a the underside of the deck at the point at which the wave formation rises and falls.
  • the rollers 27 act on the lateral deformation to cause it to assume a shape which provides a smooth wave formation.
  • the rollers do not create the lateral deformation.
  • the lateral deformation exists in the flexible deck irrespective of the presence of the rollers.
  • the purpose of the carriage is to merely cause the lateral deformation to move around the flexible deck.
  • each boom 21 is covered with a skirt 28 which travels with the boom.
  • the flexible deck 13 is composed of a plurality of sectors 31 of sheet metal material. Neighbouring sectors 31 are hingedly connected to each other to provide flexibility to the deck while preventing collapse of the wave formations. The sectors themselves also provide a degree of flexibility in that the sheet metal is resilient.
  • the connection 32 between neighbouring sectors is illustrated in Fig. 12 of the drawings. The connection comprises an inturned portion 34 at the radial edge of each sector 31 so as to define a channel 35.
  • a link element 37 extends between the sectors and includes a pair of inturned marginal portions 39 which define channels 40 which interlock with the channels 35 of the neighbouring sectors in the manner shown in the drawings. Metal to metal contact between the various parts in the connection is prevented by the presence of cushioning materials such as silicon sealant (not shown) .
  • a rib 41 of resiliently flexible material such as urethane is installed between the radial edges of neighbouring sectors.
  • a radially extending reinforcing rib 43 is centrally mounted on the underside of each sector.
  • Cushioning means 45 such as elements of rubber or other . suitable material are provided on the underside of each sector 31, one between the central reinforcing rib 43 and each radial edge.
  • the cushioning means 45 are arranged to function as buffer which prevents the sectors 31 from actually coming into contact with the ground, thereby preventing excessive noise.
  • each connecting link 47 is connected to a circular frame 46 mounted on the post 24, by way of connecting links 47.
  • the effective length of each connecting link 47 is variable to accommodate rise and fall of the sectors as the wave formations pass around the flexible deck. This is achieved by slidably supporting each connecting link 47 is a sleeve 48 which is pivotally mounted at 49 onto the circular frame 46.
  • the connecting link 47 is retained in the sleeve by a stop 50 at the radially inner end. Sliding movement of the connecting link relative to the sleeve is controlled by two springs 51, one acting on the sleeve and the other acting on the radially outer end of the sector.
  • the springs also act on spacer 53 which maintains then in a spaced condition, as best seen in Fig. 13.
  • the wave formations in the flexible deck are created by the inclusion of surplus material in the circular flexible deck. More particularly, - at least one additional sector is incorporated into the flexible deck in this embodiment to create the wave formations.
  • the creation of the wave formations is schematically illustrated in the three views which appear in Figs. 15.1, 15.2 and 15.3 of the drawings.
  • the views illustrate that a flat circular plane 56 (Fig. 15.1) can be caused to deform laterally by forming a radial slit 57 in the circular plane and expanding the slit.
  • the extent of the expansion of the slit 57. determines the amplitude of the wave formations 58 so produced as shown in Figs. 15.2 and -15.3.
  • the surplus material is introduced into the distorted plane as a sector to fill the expanded radial slit.
  • the flexible deck 13 is of laminated construction, comprising a plurality of layers (there being five layers shown in Fig. 16) .
  • Each layer 60. is composed of a plurality of sectors 61 incl ⁇ ding at least one additional sector to create a wave formation.
  • the sectors of one layer are bonded to the sectors of a neighbouring layer and each sector extends across two sectors of a neighbouring layer, as shown in the drawings.
  • This construction allows the formation of a flexible deck ⁇ o. with one or more wave formations without requiring pivotal connection between neighbouring sectors.
  • Each sector is constructed of resilient material such as sheet metal and neighbouring sectors in each lamination are spaced apart to accommodate relative movement therebetween as the wave formations travel through the sectors.
  • the flexible deck may be moulded or otherwise formed as a one-piece unit with each lateral deformation created during the formation process.
