Abstract
An elongated structural support member for truss sections of collapsible shelters having a cellular core structure including internal dovetailed wall portions and an internal medial wall portion joined at opposite ends to the dovetailed wall portions.
Claims21
In an elongated structural support member having a cellular core structure of generally oblong cross-sectional configuration, the improvement comprising:
- said cellular core structure including an outer rigid shell and internal dovetailed wall portions at opposite ends of said shell and an internal medial wall portion joined at opposite ends to said dovetailed wall portions.
An elongated truss member having a cross-sectional honeycomb configuration, the improvement comprising:
- said honeycomb configuration including first opposing recess sections having inner walls intersecting a medial wall portion and forming symmetrical second recess portions on opposite sides of said medial wall portion.
An extended tubular member of generally honeycomb configuration comprising:
- an outer shell of generally oval-shaped configuration;
- at least two hollow sections in opposing relation to one another, said hollow sections having at least three sides;
- and
- at least two polygonal hollow sections on opposite ends of said opposing hollow sections.
A support beam comprising:
- a first pair of hollow polygonal tubular sections juxtaposed to one another, each said tubular section having an inner common side therebetween;
- and
- a second pair of polygonal hollow tubular sections juxtaposed on each end of said first polygonal tubular sections having inner walls adjoining opposite ends of said common side in a generally Y-shaped configuration.
In a shelter having a canopy and a collapsible frame including vertical support legs at spaced peripheral intervals between said canopy, a telescoping center support member and truss sections extending from said vertical support legs and said center support, the improvement comprising:
- slidable mounting members located on an upper end of each of said vertical support legs;
- said mounting members each having at least two bosses with a bore therethrough, arm members defining said truss sections including an aligned bore and pivotally mounted in juxtaposition to said bosses;
- said vertical support legs having mutually aligned bores;
- position locking members located on said mounting members defined by a spring member mounted under compression between a pin lever member and a base mounting member, said spring member resiliently urging said pin lever member in a direction causing a retention pin mounted on an opposite end of said pin lever member to engage with said aligned bores;
- and
- said arm members defined by a plurality of elongated structural support members each having an outer rigid shell and internal dovetailed wall portions at opposite ends of said shell and an internal medial wall portion joined at opposite ends to said dovetailed wall portions.
