Abstract

A child's portable climbing apparatus is disclosed, having first and second climbing members. The first and second climbing members each have spaced, opposing parallel support beams and spaced, horizontal climbing bars secured to the opposing parallel support beams. The first and second climbing members are pivotally joined by a top horizontal climbing bar secured to the beams at a location offset from the longitudinal centerline, to enable the first and second climbing members to be folded into parallel alignment for ease of transportation and storage. At least one safety bar is removably secured between a selected climbing bar on the first climbing member, and a selected climbing bar on the second climbing member to adjustably position and releasably secure the climbing apparatus in a variety of heights and angular climbing positions. A safety catch is preferably used to secure the safety bar during use. A pawl may be positioned to pivot upwardly to allow the selected horizontal climbing bar to enter a slot in the safety bar. Once the climbing bar is positioned in the slot, the pawl pivots to restrict removal of the climbing bar from the slot. To remove the safety bar from the slot, the pawl must be manually raised. Two opposing pawls may be used on each side of the slot.

Dependent claims

A child's portable climbing apparatus, comprising:

a first climbing member having spaced, opposing parallel support beams, each of which is identified as having inner and outer sides as well as upper and lower sides;
with spaced parallel, horizontal climbing bars secured to the inner sides of the opposing support beams;
a second climbing member having spaced, opposing, parallel support beams each of which is identified as having inner and outer sides as well as upper and lower sides;
with spaced parallel horizontal climbing bars secured to the inner sides of the opposing support beams;
and the sides of the opposing support beams of the second climbing member spaced to be closely received within the opposing support beams of the first climbing member;
a top horizontal climbing bar secured between the opposing support beams of the first and second climbing members permitting relative pivotal movement of at least one of the first and second climbing members about the top horizontal climbing bar;
at least one safety bar is removably secured between a selected climbing bar on the first climbing member and a selected climbing bar on the second climbing member to adjustably position and releasably secure the climbing apparatus in a variety of heights and angular climbing positions, each safety bar having at least one safety catch comprising two opposing pawls which are pivotally secured adjacent to a slot in the safety bar, to releasably secure the selected climbing bar in the slot during use.

A first climbing member having spaced, opposing parallel support beams each having inner, outer, upper and lower sides;

with spaced parallel, horizontal climbing bars secured to the inner sides of the opposing support beams, the climbing bars intersect the beams at locations offset from the longitudinal centerline of the inner sides of the beams towards the upper sides of the beams;
a second climbing member having spaced, opposing, parallel support beams each having inner, outer, upper and lower sides;
with spaced parallel horizontal climbing bars secured to the inner sides of the opposing support beams, the climbing bars intersect the beams at locations offset from the longitudinal centerline of the inner sides of the beams toward the upper sides of the beams;
and the sides of the opposing support beams spaced to be closely received within the opposing support beams of the first climbing member;
a top horizontal climbing bar secured between the opposing support beams of the first and second climbing members, the top bar intersects the beams at a location offset from the longitudinal centerline of the inner sides of the beams toward the lower sides of the beams permitting relative pivotal movement between the climbing members;
and
at least one safety bar removably secured between a selected climbing bar on the first climbing member and a selected climbing bar on the second climbing member to adjustably position and secure the climbing apparatus in a variety of heights and angular climbing positions, the safety bar having at least one gravity actuated safety catch comprising two opposing pawls which are pivotally secured adjacent to a slot in the safety bar, to releasably secure the selected climbing bar in the slot during use.
