Title : "SHELTER"

BACKGROUND OF THE INVENTION

(1) Field of the Invention

This invention relates to a shelter, for providing shelter and shade, particularly in hot and windy climates.

(2) Brief Description of the Prior Art

The general object of the invention is to provide a shelter which will afford good shade, and also protection from rain, and may cover a large area, the shelter being capable of being quickly and easily erected and dismantled.

BRIEF SUMMARY OF THE PRESENT INVENTION With the foregoing and other objects in view, the invention resides broadly in a shelter of the type having a frame supporting a roofing sheet, wherein the frame includes a central member; a plurality of rafter members; connecting means for releasably connecting the rafter members to the central member so as to incline downwardly from the central member; and posts detachably secured to and supporting the outer ends of the rafter members; the roofing sheet being supported above the central member and the rafter members . Preferably the central member is a ridge truss member, its top forming a ridge, or a number of such ridge trusses releasably joined end to end, and the rafter members are substant¬ ially triangular trusses arranged in pairs extending in opposite directions, and obliquely downwards, from the ridge truss or trusses. Preferably the rafter trusses -support ceiling sections which are outwardly convergent to the roofing sheet thereabove. Other features of the invention will become apparent from the following description.

BRIEF DESCRIPTION OF THE DRAWINGS In order that a preferred embodiment of the invention may be readily understood and carried into practical effect, reference is now made to the accompany¬ ing drawings, wherein:-

FIG. 1 is a partly broken-away perspective view of a shelter according to the invention,

FIG. 2 is a partly broken-away perspective view of parts of the frame of the shelter,

FIG. 3 is a plan view showing parts of the shelter frame, and FIG. 4 is a diagrammatic cross-sectional view showing the roofing arrangements of the shelter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The shelter illustrated includes a frame consisting mainly of ridge trusses 10 interconnected end to end, pairs of rafter trusses 11 extending obliquely down, in opposite directions, from the ridge trusses, upper side members 12 interconnecting the outer ends of the .rafter trusses at both sides of the frame, and posts^" 13 supporting the outer ends of the rafter trusses. All these parts are made principally of square-section metal tube.

Each of the ridge trusses 10 is an elongated rectangle comprising an upper member or ridge 12 and a parallel lower member or tie-beam 15 rigidly interconnected at their ends by similar struts 16.

Each of the rafter trusses 11 consists of an upper member or rafter 17 and a lower member or tie-beam

18 rigidly interconnected at their ends by an inner strut

19 and a short outer strut 20, both the rafter 17 and -strut 18 inclining downwardly from the normally upright strut 19, and converging towards the outer strut 20. The strut 20 extends downwardly below the tie-beam 18 and is open-ended, to form a post socket 21. Upper side member sockets 22 extend in opposite directions from the top of the outer strut 20 in the case of the middle rafter trusses of the frame, a single socket 22 being provided for each of the end rafter trusses.

The ridge trusses 10 and rafter trusses 11 are detachably secured together by means of locking pins 23. Each of the ridge trusses 10 has secured to each side of each end a pair of spaced coaxial tubes 24, and each of the ridge trusses has secured to each side of its inner strut 20 a pair of similar coaxial tubes 25. When, as shown particularly in FIGS. 2 and 3, two ridge trusses 10 are brought together end to end, and a pair of opposite¬ ly directed rafter trusses 11 are located at opposite sides of the junction of the two ridge trusses, the pairs of tubes 24 of the ridge trusses become coaxially aligned with the pairs of tubes 25 of the rafter trusses 11. The locking pins 23, each engaged in aligned pairs of roof truss tubes 24 and rafter truss tubes 25 lock the trusses firmly together. The tubes 24 and 25 are so arranged that at one side of each rafter truss inner strut 19 the tubes 25 are above, and at the other side of the strut 19 they are below, the corresponding tubes 24 of the ridge trusses.

At each end of the frame, where there is no junction of two ridge trusses, there is provided an upright truss end-piece 26 (see FIG. 3) , which is abutted against the outer end strut 16 of the ridge truss, the end-piece 26 being provided with two pairs of tubes 24 as before described, so that locking pins 23 releasably hold together the ridge truss 10, the end-piece 26 and two rafter trusses 11.

Before the assembly of ridge and rafter trusses is locked rigidly together, as described, the upper side members 12 have their ends engaged in the upper side member socket 22 to interconnect the outer ends of the rafter trusses at both sides of the frame. The roof assembly before described is mounted upon the posts 13, the upper ends of which are closely fitted in the post sockets 21 at the outer ends of the rafter trusses 11. Each of the posts 13 has a telescopic bottom section 27, releasably locked in desired adjusted position by a set-screw 18, and having a foot 29 at its lower end. Near to its lower end, each post 13 is provided with a pair of oppositely directed lower side member sockets 30.

The shelter includes a roofing or cover sheet 31 which is stretched over the ridge truss and rafter truss assembly and is secured by any suitable means, such as lacing, to the upper side members 12 and the rafter trusses 11. The cover sheet 31 is made principally of two side sections 32 of the open weave fabric known as shade cloth connected by a central longitudinal section or ridge panel 33 overlying and extending to both sides of the ridge trusses 10, and made of a flexible waterproof material.

The shelter has a ceiling consisting of two rectangular sections 34 of flexible waterproof material, each of which is supported^* on the tie-beams 18 of the rafter trusses 11 at one side of the frame, being laced, clipped or otherwise secured to the end rafter trusses and similarly secured to the intermediate rafter truss. Owing to the substantially triangular form of the rafter trusses 11 supporting the cover sheet 31 and ceiling sections 33, the sides of the roofing sheet 31 are not parallel to the ceiling sections but, as shown particular¬ ly in FIG. 4, at each side of the shelter the roofing sheet and the ceiling section slope downwardly at different angles so that they are convergent towards" the sides of the shelter. The central longitudinal section 33 of the roofing sheet 31 covers the central opening between the two ceiling sections 34.

Side sections 35 for the shelter, made of flexible material, preferably of waterproof character, have their tops clipped, laced or otherwise secured to the upper side members 12 and at or near to their lower edges are connected to lower side members 36 which may, for example, be slidably passed through sleeves along the side sections. These lower side members may have their ends engaged in the lower side member sockets 30 of the posts 13, the side sections 35 then being vertical; or, as shown in FIG. 1, the side sections 35 may be supported in extended positions, as extensions to the roofing sheet 31, by the use of struts 37 which have their lower ends engaged with eyes 38 on the lower parts of the posts 13, their upper ends being engaged with the lower side members.

The shelter may also include end sections (not shown) of any suitable flexible sheet material.

In use, the frame may be quickly and easily erected together with its roofing or covered sheet, ceiling sections and side and end sections, without any high degree of skill being required, the telescopic construction of the posts 13 facilitating the erection of the frame on sloping or uneven ground. The shade-cloth sections 32 of the roofing sheet

33 shade the ceiling sections 34, protecting them from undue deterioration. The air layer between the ceiling sections and the roofing sheet acts as an insulation against solar heat, and .moreover convection currents of air rising from within the shelter and through the opening between the ceiling sections 34, and also of air from between the ceiling sections and the roof sheet, can pass through the shade-cloth sections 32.

In the event of rain, most of the rain water -flows down over the whole of the roofing sheet, including the shade-cloth sections, and any water which passes through the shade-cloth is finely divided or misted before reaching the ceiling sections. It is found that in windy conditions the sides of the roofing sheet and ceiling section are less liable to voilent flapping than is the case with

-

C FI conventional shelters, owing to the arrangement of these parts.

The shelter may be quickly dismantled and packed into a compact space for transport and storage. It will, of course, be understood that the particular embodiment of the invention herein described and illustrated may be subject to many modifications^' of constructional detail and design, which will be readily apparent to persons skilled in the art, without departing from the scope of the invention hereinafter claimed.
