Description:
TENT AND TEND BED FOR ASSEMBLY ON UNEVEN GROUND SURFACES BACKGROUND The present invention relates to tents and more particularly relates to a tent for accommodating uneven terrain. The invention further relates to an adjustable base for a tent which allows a user to set up the tent on sloped, uneven or irregular surfaces.

PRIOR ART Fabric-covered structures are a relatively common form of semi-permanent shelter or tent. Such structures typically can withstand moderate to severe weather conditions over extended periods of time. Fabric-covered frame tents are a prolific and popular form of temporary shelter. Such frame tents are typically relatively cheap and easy to construct on generally even and horizontal or substantially horizontal surfaces.

Frame tents can generally be erected and disassembled by unskilled persons and without specialized equipment. Frame tents typically comprise a number of relatively small lightweight frame components that can easily be transported from one site to another. Such frame tents thus are well-suited for short term accommodation in the outdoors. Frame tents typically are constructed by first assembling the roof of the tent on the ground. The roof is then lifted so that legs can be installed to support the roof.

After it is constructed, the frame tent is typically staked to the ground using stays secured at one end to ground engaging stakes and at the other end to legs which support the roof. Frame tents typically are not anchored to the ground during construction thereof, so even moderate winds can make construction of the tent more difficult. In addition, the fabric of frame tents is typically only loosely secured to the frame of the tent. The loosely secured fabric can flap in the wind, thereby stressing the frame of the tent. These problems were overcome by anchoring the tent to the ground during construction thereof.

Tents typically comprise a number of relatively small lightweight frame components that can easily be transported and assembled. One known type of tent comprises beam assemblies each comprising a roof portion and legs for supporting the roof

portion. A number of base members are secured to the ground at predetermined locations. The roof portions may be pivotally connected to the base members and rotated upwardly from the ground while maintaining the connection to the base members.

The prior at is replete with a variety of tents and methods of construction thereof.

For example United States Patent No 6,209, 558 discloses a foldable tent comprising a frame with a cover and ground sheet affixed thereto. The frame comprises a plurality of U-shaped frame members, each having a base from which extend two arms. The arms are pivotally connected to each other, and each arm is rigidly attached to a base end member which is pivotally connected to the base, whereby in the folded position the arms fold parallel to the base with the end members preferably lying normal to the base and the arms.

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.

Attempts have been made to provide a tent which is both easily erected and of simple construction.

For example U. S. Pat. 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 a cover sheet fixed to the frame. The telescoping nature of the frame members makes the tent construction generally complex, time consuming and the erection is not straight forward.

U. S. Pat. 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. Pat. 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. U. S. Pat. No. 4,748, 995, provides a tent which folds out to a larger size.

United States Patent 6,148, 834 discloses a modular tent platform system for elevating a tent structure from a ground surface to enhance comfort within the tent structure and

prevent saturation of the tent structure due to ground moisture, runoff, or precipitation includes substantially planar support panels, support braces, support legs for interlocking adjacent support panels, and attachment assemblies for securing a tent to the platform. The support legs and adjacent panels may be coupled together using channelled connecting members.

Another example of a known tent assembly is disclosed in United States Patent 5,660, 197 which teaches a Tent with an integrated, inflatable mattress. The tent has an outer sidewall supported by a pair of flexible, plastic support poles. A double cushioned floor aligns the bottom of the tent, and is permanently seamed around the perimeter of the tent. An integral, inflatable air mattress is formed between the cushioned floor and a mattress upper surface, defining an air-tight, internal volume.

On the exterior of the tent is at least one inflation valve.

In another example United States Patent 5,615, 521 discloses a tent flooring system including a support structure having two separately inflatable bladder members ; and a fastener assembly for securing the support structure beneath a tent. The first bladder member is provided with a non-slip surface for contact with the existing tent floor.

The second bladder member has a plurality of multi-directional channelling structure protrusions extending therefrom for allowing water to pass under the first bladder member during a rainstorm or the like.

United States Patent 5,031, 652 discloses an adaptable camping shelter comprising a tubular, ribbed, elevatable sleeping shelter that is compressible to a size convenient for carrying by an individual. In its preferred form, the shelter has three circular, sectioned ribs, each having a removable, handle-like projection across the bottom which serves as an elevating means. Each rib is comprised of four sections, the top section being smaller in circumference to allow its partial insertion inside the hinged side sections for consolidation purposes. The ribs are separated by braces along each side and the floor, and a cover is provided for the floor braces. The angular shape of the brace connections serves to hold the structure upright. Rotatable floor connections and optional use of adjustment extensions ensure that the unit sets firmly on the ground and reduces the risk of warping of the brace connections. A cover encloses the circumference of the ribs and is secured at the bottom between the ribs and elevating projections. A closure at each end is attachable by means of a double zipper.

Ventilation can be controlled from within. Assembly or disassembly can quickly and

easily be achieved.

Another example of a known tent is disclosed in United States Patent 4,198, 996. The invention relates to a tent which may be transported in an automobile trunk suitable for camping which comprises a frame comprised of first and second end members and two side members, each of the side members being of adjustable length to permit the distance between the end members to be varied and a first frame support means, upon which the first end members rests, adapted to be secured to a transportation vehicle ; and a second support means hingedly connected to the second end member, such that in a compressed position it lies in substantially the same plane as the frame, and in an extended position supports the second end member, the second support means being adjustable such that the second end member may be maintained at the same elevation as the first end member.

Commonly, camping tents consist of a large number of parts which require substantial time and effort to erect. Generally, commonly available tents once erected, rest on the ground thus requiring the use of ground sheets, air mattresses, and the like, to keep out the dampness and chill from the ground, and smooth out the generally uneven terrain. The susceptability of most known camping tents to dampness from the ground makes them somewhat uncomfortable. The outdoor camping shelters which offer a floor off the cold ground are generally bulky, expensive and often must be towed behind an automobile or truck. A camper tent which, in its stored configuration, may easily be transported in the trunk of a car, quickly assembled and erected, and once erected offers the user a shelter sufficiently elevated above ground to avoid the dampness and cold from the ground and the discomfort of uneven terrain. This is achieved through the use of a rigid telescoping frame supported at one end by the bumper of a vehicle and the other end by a support frame of adjustable height which is hinged to the end of the frame so that it can be swung into the plane of the frame for storage. In addition a removable centre support frame is provided for extra strength.

These are not free standing tents and are very limited in their application. United States Patent 4,427, 021 discloses a collapsible tent structure with an elevated <BR> <BR> floor. A tent structure adapted for use by game hunters, fishermen, etc. , comprises a

pair of floor-supporting frames hinged to one another on a medial axis for folding together ; a foldable linkage for supporting the floor frames in elevated positions above ground moisture; and foldable corner posts and roof frame structure for supporting a canvas covering in an area rising vertically from the floor area.

United States Patent 4,273, 306 discloses an adjustable-height support apparatus such as an adjustable-height table or bed, including a platform which is supported by a pair of leg supports, which cross each other, each leg support comprising a pair of legs pivotally connected at one end with respect to the platform for sliding movement, the opposite end being arranged to contact a support surface ; a strut being associated with each leg, the associated strut being pivotally connected at one end to the platform and the other end being pivotally connected at a location along the leg, both legs of each pair being connected together for movement in unison, and actuating means, e. g. a ram or a screw member associated with both leg supports for slidably moving the legs relative to the platform to lower or higher the platform.

DETAILED DESCRIPTION OF EMBODIMENTS The present invention will now be described I more detail according to a preferred but non limiting embodiment and with reference to the accompanying illustrations wherein: FIG. 1 is an exploded view of a skeletal frame of a tent and tent bed with adjustable legs according to one embodiment.

FIG. 2 is a perspective view of the tent bed frame structure assembled on uneven ground with legs at different elevations and with a bedding member attached to the frame.

Figure 3 shows a tent and tent bed assembled in accordance with a preferred embodiment of the invention with protective canopy attached.

Figure 4 shows a side elevation of the tent of figure 3 set free standing on uneven

terrain and with open canopy.

Figure 5 shows a perspective view of an assembled tent according to one embodiment and with canopy closed Referring to FIG. 1, there is shown an exploded view of a tent frame assembly 1 according to a preferred embodiment. Assembly 1 comprises a primary frame 2, secondary frames 3,4 and 5 which mutually engage to define an internal space 6 of a tent.

Primary frame 2 according to the embodiment shown comprises end struts 7 and 8 and intermediate strut 9. Lateral rails of frame 2 are respectively formed by members 10,11 and 12, 13, This forms a tent bed (see figure 2).

Primary frame 2 is held above ground surface 14 by means of adjustable legs 15-20.

Each leg shown may be telescopically adjustable to vary the vertical distance between primary frame 2 and ground surface 14. Thus, with this arrangement, even where a vertical distance between primary frame 2 and ground surface 14 may vary at any point within the area defined by the primary frame, the primary frame may be nevertheless be horizontally disposed.

According to a preferred embodiment, legs 15-20 are each adapted with connecting elements which allow connection of the legs to primary frame 2. For instance, leg 15 is adapted for engagement with end strut 7 and lateral rail member 13 via connecting elements 21 and 22 which respectively engage strut 7 and lateral rail member 13.

Leg 16 includes connecting elements 23,24 and 25 which respectively engage members 13,9 and 12. The remaining legs 17-20 are connected at the positions shown in a similar manner using their own connecting elements..

This embodiment of figure 1 allows a tent or tent bed constructed according to this arrangement to be assembled on sloped, uneven, rough and irregular terrain and avoids the need to seek out flat level ground for assembly of a tent and tent bed.

Figure 2 shows a tent bed 26 of a partially assembled tent of the type described with reference to figure 1 and with corresponding numbering for corresponding parts.

Primary frame 2 is shown fully assembled with a bedding support material 27 disposed in the space defined by frame 2. According to one embodiment, this may be effected by sleeves formed in the periphery of material 27. For example member 27 includes an end flap 28 which wraps around end strut 8. Connections to the remaining members of primary frame 2 may be made in a similar manner.

Figure 2 shows legs 15-20 set at various elevations to accommodate uneven ground surface 29. Legs 15-20 may be adjusted by various arrangements but in the embodiment of figure 2 each leg is shown as telescopically adjustable. For example leg 15 includes extension member 30 which has been set according to the vertical height at the location of leg 15 between primary frame 2 and ground surface 29.

Similarly, leg 17 includes extension member 31 extended to a maximum extent to accommodate the larger vertical height between ground surface 29 and primary frame 2. When tent bed 26 is assembled primary frame 2 is integral with legs 15-20 but bedding support material 27 remains horizontal regardless of the terrain elevation at any point under primary frame 2. Previously in the prior art there were attempts to elevate tent bedding off a ground surface to prevent moisture permeation from a ground surface but these could not be used on rough terrain such as on rocks or on irregular or high slope terrains. The present invention may be set up irrespective of the ground surface. For instance the tend bed may be assembled over a stream which will inevitably have an uneven bed. The adjustable legs may be manufactured from a lightweight tubular material such as but not limited to aluminium. The telescopic extension of each leg may be adjusted by means of a screw or locking pin engaging spaced holes in the respective extension member of each leg.

Figure 3 shows a fully assembled tent with numbering of corresponding parts as for figures 1 and 2 and including canopy cover 32. Cover 32 includes a flap or window cover 33 which allows air access to internal space 6 via opening 34.

A person occupying the tent space 6 will lie on surface 35. It will be appreciated that the configuration of legs 15-20 may be re arranged to suit various loading requirements. Also the tent geometry may be altered to suit multiple persons although the tent is ideal as a one or two person tent.

Figure 4 shows a side elevation of the tent of figure 3 set free standing on uneven terrain 36 and with open canopy 32 and rolled up cover 33. Legs 37 and 38 may be telescopically adjustable in the general direction of arrow 39 to vary the vertical distance between primary frame 45 and ground surface 36. Thus, with this arrangement, even where a vertical distance between primary frame 45 and ground surface 36 may vary at any point within the area defined by the primary frame 45, the primary frame may be nevertheless be horizontally disposed.

This embodiment of figure 4 allows a tent or tent bed constructed according to this arrangement to be assembled on sloped, uneven, rough and irregular terrain and avoids the need to seek out flat level ground for assembly of a tent and tent bed.

Canopy 32 also comprises cover flap 40 which allows a user to gain access to internal space 48. Flap 40 is supported by strut 41 which is stayed by stay 42. Stay 42 is anchored by anchor 43 or equivalent. Window 44 allows ventilation of space 48.

Figure 5 shows a perspective view of an assembled free standing tent according to one embodiment and with canopy closed. Figure 5 shows a tent bed 26 of an assembled tent of the type described with reference to figures 1 and 2 with corresponding numbering for corresponding parts. Primary frame 2 is shown fully assembled with a bedding support material 27 disposed in the space defined by frame 2. Figure 5 shows legs 15-20 set at various elevations to accommodate uneven ground surface 29. Legs 15-20 may be adjusted by various arrangements but in the embodiment of figure 5 each leg is shown as telescopically adjustable. For example leg 15 includes extension member 30 which has been set according to the vertical height at the location of leg 15 between primary frame 2 and ground surface 29. Similarly, leg 17 includes extension member 31 extended to a maximum extent to accommodate the larger vertical height between ground surface 29 and primary frame 2. When tent bed 26 is assembled primary frame 2 is integral with legs 15-20 but bedding support material 27 remains horizontal regardless of the terrain elevation at any point under primary frame 2. The present invention may be thus set up irrespective of the ground surface. The telescopic extension of each leg may be adjusted by means of a screw or locking pin 28 engaging spaced holes (not shown) in the respective extension member of each leg. It will be recognised by persons skilled in the art that numerous variations and modifications may be made to the invention as broadly described herein without departing from the overall spirit and scope of the invention.
