ATTORNEYS PORTABLE SHELTER This application is a continuation of Ser. No. 745,048, filed July 15, 1968, now abandoned.
BACKGROUND OF THE INVENTION The present invention relates to portable shelters, and more particularly to self-sustaining screen houses which can be supported on hard surfaces or staked to the ground, and which are particularly adapted for camping, recreation, display purposes or the like.
It is well known to provide portable screen houses which may be erected for camping or recreational purposes, but such prior art structures have various shortcomings, such as excessive costs, excessive weight, difficulty in erecting, moving or disassembling, lack of attractive appearance, or the like.
SUMMARY OF THE INVENTION The present invention has been developed to overcome these shortcomings of the prior art, and to provide a portable shelter which is characterized by its economical cost, its light weight, and the ease with which it can be erected, moved or disassembled, and further, which is characterized by the attractive appearance it has when erected.
According to one form of the present invention, a screen house is provided comprising a frame assembly and a cover of flexible material supported on the frame assembly. The frame assembly includes a central hub member, a plurality of bowed leg members radiating from the hub member and terminating at their outer extremities in lower ends adapted to be carried on a supporting surface, and a rod member extending axially upward from the hub member. The cover has a plurality of attachment means secured to the lower ends of the leg members and a dome-shaped upper portion covering the upper portions of the leg members and an axially upwardly projecting conical portion overlying the hub member. The rod member engages and supports the tip of the cone portion, and the leg members are bowed in a state of compression by the cover so as to tension the dome-shaped upper portion and to urge the hub member and its rod member upwardly to tension the cone portion. The side walls of the cover which extend downwardly from the dome-shaped upper portion are preferably made of a screen-like material.
Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

FIG. 2 is a top plan view of the embodiment illustrated in FIG. 1;
FIG. 3 is an enlarged fragmentary section taken through the center of the portable shelter, and showing one of the leg members in phantom in its unstressed position and in solid lines in its stressed position when connected to the cover;
FIG. 4 is a fragmentary enlarged section taken on the line 44 of FIG. 3;
FIG. 5 is a fragmentary top plan view of the frame assembly with a portion of the hub member in section; and
FIG. 6 is a fragmentary section taken on the line 6- 6 of FIG. 5, showing a fragment of the cover mounted on the top of the rod member and showing a fragment of the bulbous ornamental member seated on the top of the rod member.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Before explaining the present invention in detail, it is to be understood that the invention is not limited to its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.
Referring now to the drawings, the invention will be described in greater detail. The screen house or portable shelter 10 includes a frame assembly 12 and a cover 14. The cover is formed of a flexible material and has a top or dome-shaped upper portion formed of a suitable canvass or sailcloth and side wall or panel portions 18 formed of a suitable screen material, such as nylon netting. The cloth forming the top portion 16 is cut in segments so that when they are sewed together they will define the central cone or conical portion 20, the upper tip of which has a grommet 22 secured thereto. Also formed around the periphery of the top portion 16 is a decorative fringe 22. Secured to the top portion l6 are a plurality of strips or strip portions 24, each of which has at its upper end an aperture 26 and at its lower end an aperture 28. As an optional feature, the strips 24 can have a second aperture 30 for use by a stake 32, as indicated in FIG. 3, for the purpose of staking the portable shelter 10 to the ground. The side walls or screen panel portions 18 span the spaces between the strip portions 24 and are secured thereto. Access to the interior of the portable shelter 10 is gained by a passageway formed through one of the panel portions defined by the screen material 18, as shown in FIG. I.
The frame assembly 12 comprises a plurality of leg members 34, a hub member 36, and a rod member 38, extending axially upwardly from the hub member 36. Each leg member 34 has its radially inner end extending into the hub member 36, and radiates therefrom, first in a generally horizontal direction and then generally downwardly in an upright position to a terminal end which contains a pin 40 extending through the aperture 28 in the lower end of the associated strip 24.
Each leg member 34 preferably is formed with a horizontal portion 42 which is downwardly turned at 44 adjacent to its outer extremity, and a second portion 46 which defines a generally upright portion forming a continuation of the downwardly turned outer extremity. The portions 42 and 46 are telescoped together, as is best shown in FIG. 4, and the telescoped ends are normally urged apart by a coil spring 48. Preferably, the portions 42 and 46 are formed from aluminum tubing, and the downwardly turned outer extremity 44 of the portion 42 contains a rigidifying element to prevent undue stresses or bending from being imposed or occurring in the section having the smallest radius of the downwardly turned outer extremity 44.
As can be seen best in FIG. 3, each leg member 34 is designed so that it can be passed through the upper aperture 26 of the strip 24, and then bowed from its unstressed position shown in broken lines at 52 to a stressed position shown in solid lines with the tip 40 in serted through the aperture 28 at the lower end of the strip portion 24. When the leg members 34 are all inserted in the cover in this manner, each leg member 34 will be bowed causing an upward thrust of the horizontal portions 42 on the top or dome portion of the cover 14. Thus, the stressed condition of the leg members 34 and hub member 36 will cooperate to distend all of the cover, with the exception of the upper conical portion 20. In this respect it will be recognized that the coil springs 48 cooperate with the leg members in urging the horizontal portions 42 upwardly, and the rigidifying element 50 will prevent all of the bowing action to occur in that joint so as to provide a more uniform and equal distension of the cover. The coil springs 48 also facilitate assembling and disassembling of the frame assembly with the cover.
The rod member 38 is provided for tensioning and elevating the conical portion 20 of the cover 14. After the remainder of the frame assembly and cover have been erected, the rod member 38 can be inserted through the tube 54 which forms the axis of the hub member 36. The rod member 38 is hollow and contains an attached U-shape spring member 56 which has a locking pin 58 secured thereon and extending through a small hole in the side wall of the rod member 38. The pin 58 can be depressed to permit passing of the rod member 38 axially upwardly through the tube 54 and when the rod member 38 has reached the position shown in FIG. 6, the spring 56 will urge the pin 58 through the opening into a locking position on the upper side of the tube 54. The rod member 38 also includes an elongated pin 60 which forms an extension on the upper end thereof. This pin 60 is adapted to pass through the grommet 22 in the top of the cover 14 so that the tip of the conical portion 20, which includes grommet 22, can seat on the elevated rod member 38 so as to tension the top portion of the cover 14. The pin 60 can also be made sufficiently long so that an ornamental bulbous element 62 can be mounted thereon, in a manner illustrated in FIG. 6.
From the foregoing description, it will be apparent that a relatively simple screen house has been provided which can be assembled quickly, and when assembled, an extremely attractive shelter is provided. The component parts are light in weight and can be carried as a relatively small package. No particular skills are required for erecting or disassembling the shelter.
It is claimed:
