Description
Dec. 16, 1969 G. J. MARSON ETA!- OXYGEN TENT SUSPENSION Filed June 19, 1968 DVVENTORJ' GEORGE. J1 MAPSON WILLIAM H. SW/7H H La United States Patent US. Cl. 135-5 1 Claim ABSTRACT OF THE DISCLOSURE A resilient suspension for oxygen tents comprising at least one resilient member adapted to absorb stress and a limiting member for limiting elongation of the tent. A cross-strap extends between opposite corner hanging loops for limiting the distance between those corners. In a first embodiment the cross-strap is provided with an intermediate resilient member such as a rubber loop or band which permits within limitation stretching of the tent. In a second embodiment the hanger loop are themselves resilient rubber bands and are fastened at either end of the cross-strap.
BACKGROUND OF THE INVENTION Field of the invention Oxygen tent canopies and suspension systems.
Description of the prior art The prior art is evidenced by US. Patent No. 2,597,- 655 which issued May 20, 1952 to George Marson. An overhead support provided with a plurality of hangers or hooks is frame-mounted over a patient bed and the oxygen tent is removably hooked thereto as required. The
tent fabric is commonly a thin and fragile plastic film or sheet which is known to tear under applied stress thereby admitting to the enclosed volume an uncontrolled and undesirable environment. The prior art has therefore sought to provide a suspension which will absorb those stresses without imparting them to the tent fabric. The Marson patent describes a bold stride in that direction by having extensible suspension members. No limit, however, was placed on their extensibility and the tent fabric suffers accordingly.
Summary of the invention Accordingly, the present invention provides a resilient suspension for oxygen tents which prevents undo stress from being imparted to the tent fabric.
The present invention also provides a tent suspension in which elongation of certain of its members is limited.
Basically, and not by way of limitation, the persent invention provides a cross-strap between opposite edges of the upper surface of an oxygen tent at which hanger hooks may be introduced, the cross-strap having limited or no properties of elongation. In a first embodiment an element of limited expansibility is introduced intermediate of the cross-strap. In a second embodiment members of limited expansibility are introduced at either end of the cross-strap to provide hanger loops.
BRIEF DESCRIPTION OF THE DRAWING FIGURE 1 is a perspective view of the first embodiment of the present invention.
FIGURE 2 is a cross-sectional view taken across line 22 of FIGURE 1.
FIGURE 3 is a perspective view of the second embodiment of the present invention.
FIGURE 4 is a cross-sectional view taken across line 44 of FIGURE 3.
DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION Referring to the drawing, an oxygen tent 1 is provided in a first embodiment at upper side edges with heat secured tabs or loops 2. Connecting between opposite tabs or loops 2 is a cross-strap comprised of two side members 3 connected by a resilient member 4 which may be a loop or band of heavy gum rubber. Resilient member 4 permits elongation of the cross-strap but only within closely restricted limitations. A hanger 5 has end books 6 each of which may be introduced to a heat sealed loop at outer ends of the cross-strap.
In the second embodiment of the present invention a relatively non-extensible cross-strap 7 is heat sealed at its ends to opposite upper side edges of oxygen tent 1. Resilient members 8 are provided one at each end of crossstrap 7 and is adapted to receive one of the hook ends 9 of hanger 10. Resilient members 8 may be loops or bands of heavy gum rubber or other similar material extensible within well-controlled limitations. Each such resilient member 8 may be retained in place by a heat-formed pocket 11.
It will thus be seen that there has been provided an oxygen tent suspension having resilient properties but also having limitations on the resilience or permitted elongation. Undo stresses and strains are therefore not imparted to the tent fabric and a limit is placed on the extent to which opposite upper side edges of the tent may be spread apart.
While the forgoing is illustrative of preferred embodiments of the invention it is clear that other embodiments and modifications may be had within the teachings hereof and the scope of the appended claim.
What is claimed is:
1. A resilient suspension for oxygen tents, comprising:
(a) a pair of opposed corner hanging loops each at an opposite side edge of the oxygen tent;
(b) a cross-strap engaged between said opposed hanging loops for limiting enlargement of the distance between said opposed hanging loops, said cross-strap comprising a pair of side members each having an end loop at its outer end and an intermediate loop at its inner end, said end loop and said intermediate loop being integral with said side member;
(c) a pair of hanger hooks, each hanger hook adapted to engage an end loop; and
(d) at least one resilient member placed between said hanger hooks engaging said intermediate loops and acting therebetween.
