Definitions

  • This invention relates to an improvement over the swing seats described in the Complete Specification of our British Patent Application No. 9361/75 (Serial No. 1,535,728) and in the corresponding patents and applications in other countries.
  • swing seats were made of wood but it has been recognised for many years that wooden seats can inflict severe injury and a number of alternative constructions have been proposed.
  • One alternative form of construction is to make the swing seat of rubber with a metal core and seats of this kind were proposed some thirty to forty years ago.
  • the swing seats described in our earlier application are of this general type but the rubber at the periphery of the seat is moulded into a particular configuration to give enhanced safety by virtue of the impact force/deflection/energy absorption characteristic provided by the particular configuration. Swings seats in accordance with the description given in our earlier application have proved very successful in safety tests but it would naturally be desirable to have an even safer swing seat if that were possible..
  • the present invention provides a seat for a swing, the seat being of composite structure comprising a first member, which is sufficiently rigid to bear the weight of a user, and a second member of a compressible polymeric material, the first member being of substantially laminar form and the second member covering at least part of the peripheral edge of the first member, characterised in that the first member is made of a lightweight metal alloy and has a number of integrally-formed ribs depending from its underside.
  • the first member can be oblong with the ribs running parallel to the longitudinal axis of the oblong. There can be five or more, preferably, seven ribs provided.
  • the first member can be provided with a peripheral flange.
  • the first member can be rectangular and a respective rib can define the flange on each long side of the rectangle.
  • a respective angle member can be provided at each short side of the rectangle to define the flange on each short side.
  • the angle members can be riveted to the remainder of the first member.
  • the substantially laminar part and integrally-formed ribs can comprise an extrusion of aluminium alloy.
  • Each rib can be tapered and be thinnest at its distal part.
  • the second member can be as described or claimed in our earlier application.
  • United States Patent Specification 4,066,258 issued 3rd January 1978 corresponds to our British Patent Application No. 9361/75 (Serial No. 1,535,728) and provides a published description of the swing seats on which the present embodiment is based.
  • the description contained in United States Patent 4,066,258 (or any other published equivalent to 9361/75) will therefore be taken as the starting point for the present description.
  • the reader is assumed to have available a copy of United States Patent 4,066,258 or its equivalent and the disclosure thereof is incorporated herein by reference.
  • the present embodiment consists of a swing seat as described with reference to Figures 1 to 3 of United States Patent 4,066,258 with the exception that instead of the core member reference 1 of the earlier specification a different form of core member is used.
  • the core member 1 of the earlier specification is here replaced by a core member 1 1 shown in the accompanying drawings. Parts which differ from our earlier swing seat are given primed reference numerals, parts which correspond are given unprimed numerals. Parts with unprimed reference numerals will not necessarily be described again here.
  • the core member 1' consists of an extruded section 100' of aluminium alloy and two aluminium alloy angle members 102' riveted thereto.
  • a preferred alloy is one in accordance with British Standard BS1474 Grade HE30 TF to provide lightness, strength and corrosion-resistance.
  • Figure 1 shows a cross-section through the part 100'.
  • the extruded section defines a laminar body portion 104' with seven ribs 106' depending therefrom.
  • the outermost of the ribs define peripheral flanges 108', 109' and each rib is tapered being thinnest at its distal end.
  • Figure 2 is a scrap view of the underneath of the section 100' and introduces three further dimensions K, L and M equal, respectively, to 15.16, 14 and 0.58 inches.
  • FIGS 3 and 4 show elevation and plan views of one of the angle members 102'.
  • Each angle member 102' is an extruded right-angle section of aluminium alloy and has two 7/1 6 inch diameter holes 110' formed therein to correspond to the holes 3.
  • the core member 1' is assembled by riveting a respective one of the angle members 102' to each end of the section 100' with the holes 110' and 3 aligned as indicated in the perspective sketch Figure 5. Aluminium rivets (not shown), two per angle member, are used and located for example, between the second and third and the fifth and sixth ribs.
  • the angle members together with the first and seventh ribs define a peripheral flange about the core member.
  • the assembled core member 1' has the cushioning member 2 described in United States Patent 4,066,258 bonded to it, Figure 6 showing a section through the bonded structure corresponding to Figure 2 of our prior specification.
  • the peripheral flange of the core member 1' is completely embedded in the cushioning member 2 but the central part 112 of the underside of the core member is left exposed as shown in the underneath view Figure 7.
  • the swing seat with the core member 1' is even safer than our earlier swing seat because the present core member has a substantially smaller mass than the steel core member of our earlier seat so reducing force applied in impact. Moreover, the present configuration achieves this reduced mass whilst enhancing the strength and durability, retaining the resistance to vandalism of our earlier seat and keeping manufacturing costs-down.
  • the present core member can be used with other cushioning members besides that described, for example, with the cushioning member described with reference to Figures 4 to 6 of United States Patent 4,066,258, the given dimensions being modified as necessary.
