Claims7
An apparatus for a collapsible cot having sheet means for supporting a load;
- rail means for holding said sheet means;
- a plurality of leg means for positioning said rail means a predetermined distance above a floor;
- joint means for interconnecting said leg means and said rail means;
- and wherein the improvement comprises:
- a plurality of insertable pin means extending through said leg means for locking said joint means to said leg means and extending through said rail means for locking said joint means to said rail means, thereby forming a stable structure.

Apparatus for a collapsible cot comprising, in combination:
- a. sheet means for supporting a load, said sheet means including
- 1. a flexible sheet having a generally rectangular configuration;
- and
- 2. a pair of enclosing envelopes forming the long sides of said rectangular sheet for receiving said rail means;
- b. rail means for holding said sheet means, said rail means including a pair of rod-shaped rails for insertion into the enclosing envelopes, each said rail having a plurality of rod-shaped modules having an externally threaded portion at one end thereof and an internally threaded portion at the other end thereof, opposite ends of two such modules being threadably connectable;
- c. a plurality of leg means for positioning said rail means a predetermined distance above a floor, each said leg means including
- 1. a pair of corner pieces, each having
- i. a rod-shaped element including a first end and a second end;
- ii. a plurality of adjustment notches positioned at an edge of said first end and across the axis of the element;
- and
- iii. a segment connected at a substantial angle to said second end and being adapted at an upper end thereof for connecting to said joint means;
- and
- 2. a central interconnecting link for attaching to said pair of corner pieces, said link having
- i. a long U-shaped piece including a pair of upright arms and a flange connecting the arms;
- and
- ii. a pair of pivot pins located at opposite ends of said link and connecting between said upright arms at a distance from said flange for engaging the adjustment notches;
- whereby, said link attaches to said corner pieces by inserting said first ends thereof into opposite ends of said link between said pivot pins and said flange, engaging one of the adjustment notches in said first ends, and positioning said first ends against said flange;
- d. joint means for interconnecting said leg means and said rail means;
- and
- e. a plurality of insertable pin means for locking said joint means to said leg means and for locking said joint means to said rail means, thereby forming a stable structure.

Apparatus for a collapsible cot comprising, in combination:
- a. a flexible sheet means for supporting a load and having a generally rectangular shape, the long sides of the rectangle being folded back on themselves and fastened together to form a pair of enclosing envelopes;
- b. a pair of side rails insertable into the enclosing envelopes for holding said sheet means taut between said rails, each of said rails including a plurality of rod shaped sections which are threadably connectable to each other;
- c. a pair of corner pieces, each having
- 1. a rod shaped element including a first end and a second end;
- 2. a plurality of adjustment notches positioned at an edge of said first end and across the axis of the element;
- and
- 3. a segment connected at a substantial angle to said second end and being adapted at an upper end thereof for connecting to said joint means;
- d. a central interconnecting link for attaching to said pair of corner pieces, said link having
- 1. a long U-shaped piece having a pair of upright arms and a flange connecting the arms;
- and
- 2. a pair of pivot pins located at opposite ends of said link and connecting between said upright arms at a distance from said flange for engaging the adjustment notches;
- whereby, said link attaches to said corner pieces by inserting said first ends thereof into opposite ends of said link between said pivot pins and said flange, engaging one of the adjustment notches in said first ends, and positioning said first ends against said flange;
- e. a plurality of joint means for mounting said side rail means to said leg means, each joint means including
- 1. a bottom saddle having a concave shape positioned upward for supporting said side rail means and having a through hole therein;
- 2. a locking insert attached to the bottom of said saddle and having an aperture therein aligned with the through hole;
- 3. an adapter attached to the bottom of said saddle and having a hollow portion into which said upper end may be inserted;
- and
- 4. a top cap having a concave shape positioned downward for retaining said side rail means;
- f. a plurality of first pin means, each insertable through said adapter and said inserted upper end, for securing said leg means to said joint means;
- and
- g. a plurality of second pin means insertable through said top cap, said side rail means, said through hole and said aligned aperture for securing said side rail means to said joint means.
