Description

May 5, 1964 F. J. MARlNO STABILIZED PORTABLE CANOPY Filed Feb. 12, 1962 FIGZ INVENTOR FRANK J. MARINO ATTORNEY.
United States Patent 3,131,705 STABILIZED PORTABLE CANOPY Frank J. Merino, Brooklyn, N.Y., assignor to L. Marina, 11m, Brooklyn, N.Y., a corporation of New York Filed Feb. 12, 1962, Ser. No. 172,710 4 tillaims. (Cl. 135-5} This invention relates to portable canopies, and more particularly concerns extensible, free standing canopies which are stabilized against the effects of air currents thereon.
An object of this invention is to provide an improved portable canopy of the expansible-contractible type, which in its extended form presents continuous vertically dis posed panels of substantial length and height, whereby incident air currents bearing on said panels tend to cause displacement of the canopy; said canopy including means for stabilizing the canopy against such displacement.
A further object of this invention is to provide in a free standing portable canopy having extensive vertically disposed continuous panel areas, accessory panel portions which tend to stabilize the canopy against undue movement when air currents impinge on said panel areas.
Still another object of this invention is to provide an improved free standing portable canopy which includes skirt portions for stabilizing the same, said skirt portions being of minimum dimension and bulk.
Yet another object of this invention is to provide an improved free standing canopy of the extensible-contractile type, which includes auxiliary panel portions for stabilizing the same, yet does not interfere with the contraction of the canopy for storage when not in use; and which increases the basic manufacturing cost of the canopy by a relatively small amount.
Other objects of this invention will in part be obvious and in part hereinafter pointed out.
In the drawing,
FIG. 1 is a side elevational view of a stabilized portable acnopy embodying the invention, with portions cut away; and
FIG. 2 is an end elevational view thereof with portions cut away.
Essentially, the stabilized portable canopy of the instant invention comprises a plurality of inverted U-shaped frames interconnected by linkage means which permits the frames to be displaced from each other or to be brought into close proximity to each other; a flexible covering extending over the top and side portions of the frames, said covering being extended to a taut condition or pleated between the frames, as said frames are extended or contracted. Said canopy further includes skirt portions at the lower ends of the sides of the covering which act as stabilizing means for the canopy when air currents impinge on the canopy sides, tending to substantially eliminate displacement of the canopy.
Thus, as shown in FIGS. 1, 2, the portable canopy embodying the invention is generally indicated at 10. The same comprises a plurality of inverted U-shaped frames 11 which are disposed in parallel relation and interconnected by linkages 12, which permit frames 11 to be displaced from each other to the extended position shown in FIG. 1, or to be contracted, when the canopy is not in use.
Each frame 11 comprises a top portion 13 and depending side portions 14, 15 which may be splined to top portion 13 to facilitate assembly thereof. Rollers 16 are mounted in brackets 17, which in turn are affixed to the lower ends of frame portions 14, 15.
Each linkage 12 comprises a pair of similar bars 18, 19 interpivoted at their midportions as at 20. Brackets 21 are fixedly mounted on the lower portions of frame side portions 14, 15 and the lower ends of bars 18, 19 are 3,131,705 Patented May 5, 1964 pivotally connected to lateral end portions of brackets 21, as at 22, 23. Tubular collars 24 are slidably mounted on the upper portions of frame side portions 14, 15, with brackets 25 secured to said collars. The upper ends of bars 18, 19 are pivotally mounted on brackets 25, as at 26, 27.
A flexible, waterproof covering 30 of canvas or plastic coated fabric formed of cotton, nylon or other synthetic materials, is disposed over the exterior of frames 11, and is suitably lashed to frame portions 13, 14 and 15, in a manner known in the art. The covering 30 is of such dimensions as to be stretched to a taut condition when the frames 11 are extended to their extreme positions, as shown in FIG. 1. It will be apparent that the portions of covering 30 intermediate the frames 11 will pleat and fold when the frames 11 are contracted toward each other.
With bars 18, 19 of linkages 12 of substantial length, approaching the overall height of frame side portions 14, 15 it has been found that the canopy 10 may be manipulated to extend 'or contract the same, with relative ease, despite the substantial dimensions of the same and the weight of the frames 11 and associated covering 30.
As canopy 10 may be used in a free standing condition, without securing the same to stationary structures, to provide storage means for goods, or the like; it has been found that the extensive surface areas of the side panel portions 31, 32 of covering 30 give rise to inadvertent movements of the canopy when air currents impinge on said side panel portions 31, 32.
Accordingly, means is provided for stabilizing canopy 10 against undue movement due to air currents. To this end, the lower ends of panel portions 31, 32 are extended to provide elongated, narrow skirt panel portions 33, 34 which extend horizontally and outwardly of panel portions 31, 32. Panel portions 33, 34 are supported in a horizontal position by angle brackets 35 whose horizontal portions 36 are welded at their inner ends to lower portions of side frame portions 14, 15.
The vertical portions 37 of brackets 35 have secured to the lower ends thereof, wheel brackets 17A and wheels 16A are rotatably mounted on said brackets 17A. Panel portions 33, 34 are suitably lashed to brackets 35 and provide an elongated, horizontal taut surface when the covering 3t and frames 11 are in an extended condition.
In the event that the canopy 10 is subjected to air currents, such currents on impinging on panel portions 31, 32, will be diverted in vertical directions along said panel portions. The air currents moving downwardly along panel portions 31, 32 will impinge on stabilizing panels 33, 34 and tend to anchor the canopy 10 against undue movement. Rollers or wheels 16A in outrigger relation to the inner rollers 16, also act as stabilizing elements against possible rocking movements of the canopy.
It is understood that with canopy 10 having panel portions 31, 32 of substantial height and length, incident air currents are diverted and utilized to neutralize their otherwise tendency to impart movement to the free standing canopy 10.
The frames 11 may be braced by diagonal bars 35 and the opposite ends of covering 30 is provided with triangular end flaps 36 at the corners of panel portions 31, 37 and 32, 37; for enclosing the corner portions of the end frames 11. The frames 11 and linkages 12 may be formed of aluminum or other light weight metals or alloys, to minimize the weight of the same. Also, the frames andlinkages may be of any suitable cross section to attain maximum strength.
The stabilizing panels 33, 34 may be varied as to width. However, panels of 18" width were found highly effective when associated with side panel portions measuring about 14' by 20'.
As various changes might be made in the embodiment of the disclosed invention without departing from the spirit thereof, it is understood that all matter herein shown or described shall be deemed illustrative and not limiting except as set forth in the appended claims.
What is claimed is:
1.
