The present invention relates to the construction of tent frames, and more particularly to the construction of a tent with its covering material fixed to

the frame to facilitate quick and easy erection of the tent.

It is a general disadvantage of known tents that they are generally complex and therefore difficult and time consuming to erect. Also this adds to

the manufacturing costs.

Many attempts have been made to provide a tent which is both easily erected and of simple construction. The following is a list of such attempts.

U.S. Patent no. 2,960,993 discloses a tent having U-shaped frame members, which are of a telescoping construction, to assist in the folding of the frame, with the cover sheet fixed to the frame. The telescoping nature of the frame members makes the tent construction generally complex, and the erection is not straight forward and is generally time consuming.

U.S. Patent no. 3,405,721 , discloses a tent having U-shaped frame members, but the cover sheet and ground sheet are affixed to the frame after

the frame has been erected. Thus the erection of the tent is not straight forward and is generally time consuming.

U.S. patent no. 3,865, 123 discloses a tent which has a frame of a generally U-shaped construction, but has a zipper fastener on the ground sheet

to facilitate folding of the frame. Again this adds to the cost and complexity of the tent.

U.S. Patent no. 4,748,995 , by Guiseppe Viglione, overcomes most of the disadvantages of the prior art. However the present invention provides an improvement of this U.S. Patent in that it provides a tent of the same folded size as an equivalent tent made in accordance with U.S. Patent no. 4,748,995, but which folds out to a larger size.

In one broad form the invention comprises a foldable tent comprising:

a frame; and a cover and ground sheet fixed to the frame so as to provide an

enclosed living area when said tent is erected, said frame comprising a plurality of frame members, each of generally U-shaped configuration, with an elongated base having two arms extending therefrom, with the arms cooperating to form two frame sides,

a pivot assembly for each frame side to which the free ends of the arms

of the respective side frames are attached so that the arms of each frame side

pivot about a first folding axis on said respective pivot assembly, whereby said

frame members are pivotal from a first folded position, wherein said frame members are in a an abutted relationship, to an erected position in which the

frame members are angularly spaced about said first folding axes,

brace means extending between said frame members to support the

frame members in the erected position, an end member located at each end of the base and pivotally connected thereto, wherein the respective arms are rigidly connected to the extremity of

the respective end member, thereby enabling pivoting of the end member and

attached arm, about a second folding axis extending generally within the plane of the respective base and normal to the direction of extension of the base

member and the arm, whereby in the erected position the arms project away

from the base , with the second axes of the arms of a side being generally coterminous when the tent is folded, the end members of the first side being longer than the end members of the second side so that in the folded position

the arms of the second side lies between the bases and the arms the first side.

A preferred form of the invention will now be described with reference to

the accompanying drawings, in which:

Figure 1 is a schematic perspective view of a foldable tent according to

one embodiment of the present invention;

Figure 2 is a schematic side view of the tent shown in figure 1 ;

Figure 3 is a schematic view of the frame of the tent shown in figure 1 , in a partially folded position,

Figure 4 is a schematic sectional end view of the bracing employed in

the tent shown in figure 1 ;

Figure 5 is a schematic plan view of the frame shown in figure 2, in a

partially folded position;

Figure 6 is a schematic plan view of the frame shown in figure 2, in a

completely folded position; and

Figure 7 is a schematic view of a corner assembly of the frame shown in

figure 2.

In figure 1 there is schematically depicted a tent (10) having a frame

(11) which supports a cover sheet (12) which rest upon a ground sheet (13).

The frame (11 ) comprises a plurality of frame members (14), each of general U- shaped configuration. The frame members (14) are formed of metal tubing having a rectangle or square cross section. The cover sheet (12) and the

ground sheet (13) are permanently fixed to the frame members (14) by straps (15).

The sheet (12) provides a roof surface (16), a rear wall (17) and two side walls (18). The front wall of the tent (10) is provided with one or more foldable panels (19) which provide access to the interior of the tent.(10).

It should be appreciated that the tent (10) is self supporting and will

generally not require anchoring to the ground. However if the weather conditions so require it, the tent (10) could be tied down by means of lines (20). Still further the ground sheet (13) could be provide with eyelets adjacent its periphery through which pegs could be driven to further aid in anchoring the

tent (10) to the ground.

The frame members (14) are held in an erected position by means of braces (21 & 22). One extremity of the brace (22) is pivotally attached to the frame member (14) resting on the ground while one extremity of the brace member (21 ) is pivotally attached to the frame member (14) which is generally

T/A 7/00296

vertically extending, as shown in figure 2. The other two extremities of the

braces (21 & 22) are attached to a slide (23), slidably received in a channel

(24) defined in the frame member (14), as shown in figure 4.

Each of the frame members (14) is of generally U-shaped configuration

so as to have an elongated base (25) from which extends two arms (26 & 27). Each of the arms (26 & 27) can be attached to its associated base (25) by

means of a corner assembly (28), as shown in figure 7.

The extremities of the arms (26) are pivotally attached to a pivot

assembly (29) while the extremities of the arms (27) are pivotally attached to a pivot assembly (30). Thus the frames 14 are able to pivot about the same or a

plurality of parallel axes so as pivot from an erected position as shown in figure 2 to a folded position as shown in figure 3. Preferably the ground engaging

member (14) fixed to the pivot assemblies (29 & 30).

Each of the arms (26 & 27) are rigidly attached to the respective base

end members (32 & 33), which are pivotally attached to the base (25) by means

of pins (31 ). The pins (31 ) define pivot axes normal to the axis or axes defined

by the pivot assemblies (29 & 30). The end member (32) is longer than the end

member (33). The relative lengths of the portions (32 & 33) enables folding of the legs (26 & 27) to the position shown in figure 5 with the cover sheet (12)

and the ground sheet (13) still attached to the frame.

Each corner assembly (28) comprises a corner member (34) having two projections (35), which mate within the associated member to be joined.

Fasteners are then passed through the holes (36) to effect a join.

Because the arms (26 & 27) and their respective base end members (33

& 32) pivot from positions along the base (25), a fully folded tent of less lengtl ι

than the length of the base is obtained. Further a larger tent, made in

accordance to the present invention compared to that made in accordance to U.S. Patent no. 4,748,995, can be folded out from the same length folded package.

It should be obvious to people skilled in the art that variations and

modifications can be made to the above description without departing from the scope or spirit of the present invention.
