Inf. ci. A4sf 1/12, 1/161 U.S. Cl. 135-1 8 Claims ABSTRACT OF THE DISCLOSURE The invention essentially relates to the construction of a windbreak tent intended to permit sheltering from the wind whilst remaining exposed to the sun, and preferably made in the form of a pliable sheath capping a reinforcing grid or frame connected to a ground-sheet or the like.

BACKGROUND OF THE INVENTION Field of the invention This invention relates to tents and like protective covers, which provides a windbreak to permit people or articles under it sheltering from the wind whilst remaining exposed to the sun, and which may be converted simply into a normal tent providing shelter from the wind and/ or the sun as well as from outsiders looking in, so as to represent a conventional sheltering tent thereafter.

SUMMARY According to the present invention a tent or the like comprises a reinforcing frame connected to a groundsheet or the like, plastic posts starting, for example, from a series of reinforcing points of the sheet and terminating at a top element in the case of a tent of gothic or ogival shape.

BRIEF DESCRIPTION O'F THE DRAWINGS FIG. l is a perspective view of a windbreak tent;

FIG. 2 is a cross section of a post base;

FIG. 3 is an enlarged view of a base corner;

FIG. 4 is a partial cross section of a folded post;

FIG. 5 is a similar view to FIG. 4 showing the post erected; and

FIG. `6 is a perspective view of the top element of the tent.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, a windbreak tent comprises a sheath 10 of transparent plastic material capping a reinforcing frame made up of four posts 11-14 starting from the corners of a square ground-sheet 15 or the like and joined together around a top element 16 or block.

Each of the posts consists of a tube of relatively pliable and resilient plastic material comprising two sections, that is to say a bottom section such as 11A and an upper section such as 11B, which in the operative position are held one in the extension of the other by a coupling sleeve 18. As apparent in FIG. 2, the bottom terminal part of the post element 11A for example, is closed olf by a plug 19 made of wood for example, immobilized relative to the tube by screws 20 or by any other means such as gluing. This plug is tted by an axial screw 21 and a washer 22 to a corner reinforcement (not shown in detail) of the ground-sheet 15, Whose sides are advantageously raised within the tent, as shown at 23 for example.

The adjacent terminal parts of two elements such as 11A and 11B of each post are closed olf, respectively (see FIG. 4), by two cylindrical sections 24 and 25, of which one is set back slightly and the other projects slightly,

y 3,448,748 Patented June 10, 1969 which are axiallytraversed by an elastic cord 26. In the folded position of the post,'the coupling sleeve 1'8 rests on an abutment ring 27 projecting from the upper tube section 11B at a distance from its extremity corresponding substantially to the length of the sleeve, whereas the section 11A bears a similar ring 28 at a distance from its extremity corresponding substantially to half of the said length.

With an arrangement of this kind, it suffices to olferup the upper half-post 11B in extension of the lower halfpost 11A (FIG. 5), for assembly to occur automatically: the projecting and preferably slightly chamfered or tapered extremity of the cylindrical section or plug 25 drawn back by the resilient action of the cord 26 engages in the recess formed to this end by the other plug 24 in the extremity of the associated half-post, whereas the sleeve 18 mounted in a sliding t on the tubes, assumes its position on the lower abutment ring 28 by sliding under the action of its own weight.

The upper terminal part of each post is engaged on an end-piece 29 screwed for this purpose into a top element or block 30 (FIG. 6r) comprising a corresponding number of lateral surfaces, whereas a decorative apex element 31 in the form of a sphere for example, is screwed into its upper surface.

The sheath 10 for capping the reinforcing structure thus formed, starting from and above the ground-sheet 15, is formed by four panels cut from transparent plastic material sheet, namely two lateral panels, 32, 33, a rear panel 34 and a front panel 35.

In this case, each of the panels has the form of a curvilinear triangle of gothic arch form, with two curvilinear sides surmounting a suitably reinforced rectilinear base. The adjacent curvilinear sides are joined to each other by a welding seam such as 36, the four ridge-lines thus formed terminating at the centre of the sheath in a top ring shown diagrammatically at 38 in FIG. 6, this ring being adapted to engage over the decorative element 31.

On the other hand, each of the ridge-lines 36 at its lower extremity (FIGS. 2, 3) terminates at a corner reinforcement 39 bearing an oval eye 40y adapted to operate in conjunction with a hooking stud or the like 41 -on the corresponding corner reinforcement of the groundsheet.

The front panel 35 has a wide passage opening 42, the perimeter of this opening being reinforced by a marginal strip 43, which is naturally extended at 44-45 on the uncut terminal parts of the base of the front panel; if desired, these parts may moreover be tensioned in prolongation of each other and towards each other, by means of an elastic cord 46 fitted between two hooks 47.

The reinforcements are preferably made of impregnated fabric which may be joined to the plastic fabric of the sheath by bonding or welding.

At the bottom of each of the other panels 32, 33 and 34 of the sheath is an extension in the form of a rectangular strip having a part 146 facing the bottom of the panel along a predetermined height, and a part 147 forming a sill. The part 146 carries a row of swivel hooking studs or the like 48 adapted to receive and secure corresponding eyes 49 spaced along the outer edge of the sill so that the latter may be folded on itself to form a tubular structure which may be filled with sand, for example, in order to ensure stability of the tent under the action of the wind.

It is suicient in most cases moreover, to load the sill or flap 147 with sand to ensure stability of the tent,- without having to attach this flap to the swivel hooks 48.

VThe windbreak tent thus formed may be converted into a sheltering tent, such as a beach or unrobing tent, for example; for this purpose, a complementary sheath (not shown) of opaque cloth is provided, of similar form to the transparent sheath. This complementary sheath may have eyes to t over the swivel hooks such as 41 and 48 and may comprise a displaceable panel or ap in alignment with the front panel 35 or merely in alignment with the passage opening 42 wrought therein.

This movable panel or ap may have any suitable securing means such as a slide-fastener fitted at each side, or it may be constructed to be raised to form an awning with two posts in known manner.

With gothic arch tent shapes as herein described, a different number of posts and ridges may be used, the posts being made of a single piece or made up of more than two sections. Other shapes may be employed such as a truncated pyramid, a parallelepiped, or a semi-cylinder. The stabilising device formed by the loaded flaps or sills may be complemented or replaced by any conventional devices such as stakes or guy wires.

If desired, increased ventilation of the windbreak tent may be provided by arranging windows or other variable opening apertures in the side panels 32, 33, for example, in the construction of the drawings.
