Abstract
A horizontal ladder particularly useful in playgrounds includes two end structures, two elongated members extending between the end structures and handholds attached to the cables. Since the ladder does not need any horizontal support members it is safer to use than standard horizontal ladders.
Claims13
A horizontal ladder for a playground comprising:
- a first and a second end structure;
- four cables secured between said first and second ends, said four cables including first and second upper cables, and first and second lower cables disposed substantially below said first and second upper cables, respectively;
- and
- a first set and a second set of cells arrange and constructed to form handholds for traversing from said first to said second end structure, each cell of said first set being mounted between said first upper and said first lower cable, and each cell of said second set being mounted between said second upper and said second lower cable.
1 more element
A structure for playgrounds which can be traversed hand-to-hand comprising:
- an elongated support member extending horizontally;
- handhold means including a flexible cable extending in parallel with and being disposed under said supper member, said handhold means being arranged for grasping with a hand;
- and
- a plurality of coupled members extending in a spaced relationship between said support member and said handhold means for supporting said handhold means.
1 more element
A horizontal ladder comprising:
- a pair of ladder structures each;
- first and second end structures;
- and
- first and second substantially coextensive longitudinal structures extending above ground between said end structures, said ladder structures being spaced at a predetermined distance to define an unobstructed space therebetween, each longitudinal structure including an elongated support member extending between said end structures;
- and a set of grasping means extending downwardly from said support member, said grasping means includes a plurality of hingedly coupled cells secured to one of said support members, each cell being arranged and constructed to from a handhold.
