The inventor claims no sponsorship or support of any kind from any other party.

FIELD

The present application is in the field of portable shelters (e.g. tents and tarps) such as those used by backpackers.

BACKGROUND

Backpackers and other outdoor users frequently use tent shelters to gain protection from the elements such as rain, insects, and wind. These shelters are frequently erected with a pole set formed from flexible tubing (referred to as tent poles), which can support the fabric components to provide a shelter that is lightweight and mostly or entirely freestanding, such that few or no tent stakes are required.

These tents will typically be a “doublewall” design where the floor is sewn to a set of interior walls to form an enclosed “inner tent”, while a detachable waterproof outer layer (referred to a “canopy” or “fly” or “flysheet”) is positioned to generally cover the inner tent. This doublewall design with separate canopy and inner tent components is the most common configuration, but other configurations exist including an inner tent that is itself not fully enclosed but becomes fully enclosed by being permanently affixed to the canopy to collectively form an enclosed single piece tent that is called a “singlewall” or “hybrid” design (due to the partial or complete absence of interior walls).

Existing tent designs supported by flexible tubing are commonly based upon a canopy that has a hexagonal shape at the canopy base (bottom perimeter) such that a rectangular floor can be provided with triangular vestibules (non-floored areas) on both sides. However, this geometry has several common downsides. On lightweight models, it is generally too heavy to extend the pole set to all six corner vertexes of the hexagonal canopy base, so the pole set is reduced such that it commonly only extends to four of the six corner vertexes (corresponding to rectangular floor corners inside) which leaves the final two vertexes of the hexagonal base without structure and needing to be staked out. Additionally, using a pole set that extends to only 4 of 6 corner vertexes, means that the tent can usually not form its full preferred shape with only the canopy and pole set because there is not a direct line of fabric between all adjacent pole tips to define their position. Attempts to assemble a hexagonal based canopy with a pole set that extends to only 4 corner vertexes with no other supporting elements generally results in the canopy and pole set deforming from their preferred shape. As such, these tents are commonly pitched with “inner first” where the pole set is first connected to an inner tent that has a rectangular floor capable of defining the locations of the four tips of the pole set, while the hexagonal based canopy is added later and the additional corner vertexes are staked out. This inner first pitching method is common but has the downside that the inner tent gets wet during setup in the rain. Previous solutions to this problem generally consist of incorporating other elements to aid in defining the preferred shape of the pole set (e.g. a groundsheet, stakes, additional cords or straps) but with resulting greater weight and complexity.

Some prior freestanding tents have used a rectangular canopy base and with a pole set extending to all four corner vertexes. These tents are more readily capable of pitching without the inner tent and other support since the canopy and pole set both extend to the same four corner vertexes, but these designs have always used a rectangular floor shape. With some designs this rectangular floor generally fills the entire area of the rectangular canopy to leave a lack of vestibules. Prior attempts to create vestibules while using a rectangular floor inside a rectangular canopy base have reduced the size of the rectangular floor to leave vestibules along 1 or more sides. This is a viable design, but with a rectangular floor those rectangular vestibules must span the full side of the tent (which results in an inefficient use of space as the vestibule area is widely distributed into a long strip rather than contained into a more centralized area).

BRIEF SUMMARY OF THE INVENTION

Disclosed herein is an improved geometry for a freestanding tent canopy with a simpler quadrilateral shaped canopy base (rather than the more common hexagon) and with a distinctive floorplan involving positioning at least one side or two opposing sides of the floor to be oblique relative to the canopy base, so the tent can provide the floorplan elements found in hexagonal tents including conveniently shaped vestibules, while simplifying the structure such that the tent can be fully assembled into its preferred shape with only the canopy and a pole set extending to only four corner apexes. This design requires no other elements (e.g. no mandatory floor, stakes, guylines, straps, or inner tent) to form its preferred shape. This architecture also enables the tent to offer a wider variety of pitching options including inner tent first, canopy first, and canopy only pitching.

According to one aspect of the invention, there is provided a tent shelter comprising: a canopy having a canopy base; a floor configured for ground laid placement in a predetermined position relative to the canopy for overhead coverage thereby in an erected state of said canopy; and a pole set configured for cooperatively assembly with canopy to support same in said an erected state providing said overhead coverage of the floor; wherein the canopy base shape is a quadrilateral of either a rectangle or isosceles trapezoid type with four corner vertexes in said erected state of the canopy, the pole set is configured to extend to all of said four corner vertexes of the canopy base when cooperatively assembled therewith, and the floor is a non-rectangular quadrilateral in shape and is configured to lie with at least one side thereof substantially oblique to a respectively neighbouring side of the canopy base in said predetermined position, so as to thereby leave at least one area unfloored as a vestibule at a corner vertex of the canopy base.

In one embodiment, the quadrilateral canopy base shape of either a rectangle or isosceles trapezoid type is a generally rectangular type, and the at least one side of the non-rectangular quadrilateral shaped floor that is substantially oblique to a respectively neighbouring side of the canopy base in said predetermined position includes two opposing sides of the floor thereof that are configured to lie respectively parallel to each other but respectively oblique to their said neighbouring sides of the canopy base, whereby said at least one area unfloored as a vestibule at a corner vertex of the canopy base comprises at least two equally sized areas unfloored as vestibules situated at diagonally opposing corner vertexes of the canopy base.

In another embodiment, the quadrilateral canopy base shape of either a rectangle or isosceles trapezoid type is a generally rectangular type, and the at least one side of the non-rectangular quadrilateral shaped floor that is substantially oblique to a respectively neighbouring side of the canopy base in said predetermined position includes one side of the floor thereof arranged to lie oblique relative to a neighbouring side of the canopy base while the opposing side of the floor is arranged generally parallel to its neighbouring side of the canopy base, whereby said at least one area unfloored as a vestibule at a corner vertex of the canopy base includes an unfloored vestibule area at one corner vertex of the canopy base without a matching unfloored vestibule area at the diagonally opposite corner of the canopy base.

In another embodiment, the quadrilateral canopy base shape of either a rectangle or isosceles trapezoid type is generally an isosceles trapezoid type, and the at least one side of the non-rectangular quadrilateral shaped floor that is substantially oblique to a respectively neighbouring side of the canopy base in said predetermined position includes one side of the floor thereof arranged to lie oblique relative to a neighbouring side of the canopy base while the opposing side of the floor is arranged generally parallel to its neighbouring side of the canopy base, whereby said at least one area unfloored as a vestibule at a corner vertex of the canopy base includes an unfloored vestibule area at one corner vertex of the canopy base without a matching unfloored vestibule area at the diagonally opposite corner of the canopy base.

DETAILED DESCRIPTION OF THE INVENTION

Referring FIGS. 1-6, illustrated therein are different embodiments of a novel design for a freestanding lightweight tent that avoids common disadvantages with existing lightweight shelters supported by tent poles. The invention combines three key features, which are an outer canopy 1 (also referred to as a “fly”, “flysheet” and/or “exterior wall”) with a quadrilateral shaped base 2 (bottom canopy perimeter), a pole set 7 comprised of tubular poles (referred to as “tent poles” and “pole set”) that connect to all four of the canopy base's corner 3 vertexes, and a floor 4 that has a substantially non-rectangular quadrilateral shape so as to be oblique to one or more sides of the canopy base 2 which creates vestibules 6 at one corner 3 or two diagonally opposite corners 3 inside the canopy base 2 (FIG. 1). As such, the tent has common conveniences like vestibules 6 inside of a simpler quadrilateral canopy base 2 shape, which enables it to be capable of forming its full preferred shape without support from other elements besides the canopy 1 and pole set 7. This enables the tent to be pitched in a wide variety of configurations (e.g. canopy-first, inner-first, canopy-only) and with other functional advantages, including elimination of the requirement to stake out the vestibules 6 (compared to most hexagonal tents) to establish the full preferred shape.

The canopy 1 is typically constructed from woven fabric but can be made from a variety of weather proof or weather resistant materials including laminated fabrics, woven fabrics, and composite materials. The canopy 1 has a base 2 which is a quadrilateral. Most typically the quadrilateral base 2 will be rectangular (i.e. approximately 90 degrees at all four corners 3; per the first and second embodiments shown in FIGS. 1, 2, 4 and 5) but can alternatively be an isosceles trapezoid (per the third embodiment shown in FIGS. 3 and 6). The isosceles trapezoidal base 2 may be desirable for a single vestibule 6 embodiment as it enables a consistent floor 4 width, while the rectangular canopy base 2 is suited for both single and dual vestibule 6 embodiments. It should be understood that the shape of the canopy base 2 is the important attribute of the canopy 1 shape (as opposed to other base 2 shapes, such as a pentagon or hexagon) and the invention is not reliant on aspects of the canopy 1 shape. The dimensions of the base 2 will vary based on the intended capacity of the shelter (e.g. one person, two person). When the base 2 shape is a provided as a rectangle, the length will typically exceed the width. The length of the rectangular base 2 will typically be seventy five to one hundred and ten inches long such that the tent is long enough to accommodate an adult whether laying parallel or oblique to the lengthwise sides of the canopy base 2. The width of the rectangular base 2 will vary with the number of intended occupants (as a wider base 2 enables a wider floor 4) and will typically be forty to seventy five inches wide in models intended for one occupant, and fifty to ninety inches wide in models intended for dual occupants. In higher capacity models the width can exceed the length. The sides of the rectangular canopy base 2 considered to be the lengthwise sides can typically be identified as the two opposing sides which remain relatively similar in length as the person capacity of the tent changes, as the two opposing sides where one or both sides contain a doorway, and/or as the two opposing sides where one or both sides are substantially oblique to the floor 4 such that the largest vestibule 6 area(s) are neighbouring these sides. When the base 2 shape is a provided as an isosceles trapezoid (rather than a rectangle) it will typically be intended for one occupant. The legs of the isosceles trapezoid base 2 can be referred to as the lengthwise sides of the canopy base 2 and these will typically be seventy five to one hundred and tent inches long such that the tent is long enough to accommodate an adult laying parallel to the lengthwise sides of the canopy base 2. The width of the isosceles trapezoid base 2 will vary but will typically be thirty to fifty inches wide at the narrow end of the trapezoid and fifty to seventy five inches wide at the wider end, in models intended for one occupant. Wider two occupant models are possible.

Aside from the base 2 shape, the rest of the canopy 1 shape, in its erected state with the pole set 7, will generally resemble a dome (half sphere) but the exact shape can vary widely. Typically the canopy 1, in its erected state, will rise to a peak height of thirty five to fifty inches. The canopy 1 has at least one door 5, which can vary in position but will be provided somewhere along one or both of the two lengthwise sides of the canopy base 2 such that the occupants have wider “side entry” doors 5 rather than narrower doors on the typically shorter end walls of the tent. Typically there will be two canopy doors 5 (one on each lengthwise side) but a single door 5 can be provided and may be preferred, such as on versions intended for a single occupant. Placement of a door 5 at one or both lengthwise sides of the tent enables the door 5 to be accompanied by a vestibule 6. Typically there will be a vestibule 6 provided at each door 5.

A unique element of the invention is the shape of the floor 4, which is modified in distinctive fashion from a traditional rectangle floor 4 shape and is instead has a non-rectangular quadrilateral shape, so as to leave one or two triangular areas inside the canopy base 2 area but outside the floor 4 area unoccupied by the floor 4 as vestibules 6. More specifically, the floor 4 lies at an oblique orientation to the canopy base 2 along one or both of the lengthwise sides thereof, so as to create one or two vestibules 6 at the canopy base 2 corners 3 with a generally triangular shape. A dual vestibule 6 embodiment whose floor 4 is characterized by a dual-sided lengthwise obliqueness relative to the canopy base 2 forming dual diagonally opposing vestibules 6 is shown in FIGS. 1 and 4. In this dual vestibule 6 embodiment, the floor 4 is shaped as a non-rectangular parallelogram whose two lengthwise sides lie in oblique orientation to the canopy base 2 but in approximately parallel orientation to each other, so as to create vestibules 6 in two opposite corners 3 of the canopy base 2. The angle of each of the other two sides of the floor 4 (i.e. the widthwise ends thereof) can vary. Commonly these widthwise sides of the floor 4 will be generally parallel to the widthwise sides of the canopy base 2 but in other variations, the orientation of the floor 4 widthwise sides may vary from such parallel relation to the canopy base 2 ends, such that the ends of the floor 4 are mildly oblique 12 to the canopy base 2 (as shown in FIG. 8). This can be done to improve lengthwise tensioning on the floor 4 when the floor 4 corners are anchored to the neighbouring canopy base 2 corners 3.

When the tent is provided in a dual vestibule 6 configuration, most commonly the canopy base 2 will be a rectangle such that the approximately parallelogram shape of the floor 4 creates dual vestibules 6 at two diagonally opposite corners 3 of the canopy base 2. The single vestibule 6 embodiments are characterized by obliqueness along only one of two lengthwise sides of the canopy base 2 relative to their neighbouring sides of the floor 4 and are shown in FIGS. 2, 3, 5 and 6. In the single vestibule 6 embodiments, the floor 4 has one lengthwise side that is approximately parallel to respectively neighbouring lengthwise side of the canopy base 2, while the other lengthwise side of the floor 4 is oriented obliquely to its respectively neighbouring lengthwise side of the canopy base 2 to create a vestibule 6 along that lengthwise side. In these single vestibule 6 embodiments, the canopy base 2 can be a rectangle (FIGS. 2 and 5) such that single vestibule 6 has a generally right angle triangular shape which tapers narrower such that the floor 4 widens towards the non-vestibule 6 end of the tent. Alternatively, the canopy base 2 can be an isosceles trapezoid (FIGS. 3 and 6) such that the floor 4 remains are a more consistent width towards the non-vestibule 6 end of the tent and instead of the floor 4 widening the canopy base 2 narrows. When an isosceles trapezoidal canopy base 2 is used, the two ends of the canopy base 2 will be generally parallel to one another while two lengthwise sides (or “legs” of the trapezoid) will be non-parallel such that they are wider apart at the vestibule 6 end of the tent and closer together at the non-vestibule 6 end of the tent.

The floor 4 may consist of a separate piece of material (e.g. a groundsheet) from the rest of the tent to provide protection from the ground, but more commonly the floor 4 will be connected to another part of the tent in a permanent or removable fashion. A common design is to equip the tent with an inner tent of separate character from, but attachable and detachable in relation to the canopy 1. This inner tent will usually consist of a floor 4 sewn to interior walls and an interior roof to form a full inner tent of self-enclosed character, which then is positioned inside the canopy 1. Alternatively, a partial inner tent (e.g. the inner tent possessing only a set of some interior walls and no roof) may be permanently attached to the interior of the canopy 1 such that the inner tent and canopy 1 collectively form a fully enclosed space above the floor 4. This partial inner tent configuration is often referred to as a “hybrid” or “singlewall” design. A wide range of methods are available to interconnect the floor 4, interior walls, and canopy 1, but such details are not essential to a working understanding of the invention, and thus not embellished on herein. Any doors on the interior walls of such inner tent may vary in quantity, size and/or location, but generally will be aligned with the canopy doors 5 along one or both lengthwise sides of the tent.

The pole set 7 is constructed of hollow tubing that is often constructed of aluminum or carbon fiber, but the pole material can vary. The pole set 7 can connect to the rest of the tent in a variety of ways, including connecting to the exterior of the canopy 1 via fabric sleeves or with clips, or interior the canopy 1 where it is held by the canopy 1 walls and/or via connections to the canopy 1 or inner tent. A key feature of the pole set 7 is that, in the erected state of the tent, the pole set 7 extends to all four corner 3 vertexes of the canopy base 2, such that the canopy 1 and pole set 7 can together be fully erected into their preferred shapes without requiring of other elements to aid in establishing the shape (e.g. guylines, stakes, straps, groundsheet, inner tent). This is known as a fully freestanding tent. Stakes and guylines will commonly be used for further anchoring and stabilization, but the tent of the present invention is capable of being assembled into its fully erected and preferred form without requiring these anchoring and stabilization elements. Aside from the characteristic of connecting to all four corners 3 of the canopy 1, the erected pole set 7 can vary widely in form and these variations are inconsequential to the claimed invention. Commonly, the pole set 7 may use dual arches 8 (FIGS. 1, 5 and 7), with each arch crossing over the other near the peak and joining to opposite corner 3 vertexes. Other practical embodiments include joining the dual arches together in the upper portion of the tent to form a single arch with forked ends 10 (FIGS. 2, 3, and 7D), or using dual arches that cross over each other twice 11 such that each arch connects to adjacent corners 3 (FIG. 7E). The pole set 7 may incorporate other elements to modify or increase the interior volume, such as pre-bent pole sections to shift the arch shapes away from a constant radius, and/or a cross bar 9 to widen the upper portion of the tent. There are almost an unlimited quantity of variations that can be made to the pole set 7, but the claimed invention is not specific to any particular implementation of the pole set 7, aside from its particularly connectivity to all four corner 3 vertexes of the canopy base 2.

It is to be understood that the dimensions, geometry and features described herein are variable and should be given reasonable interpretation. Those familiar with shelter design will find it apparent that the previous described embodiments are exemplary versions only, and other variations may exist which fall within the scope of this invention. The presently preferred embodiments are examples of how to make and use the invention, and are presented to enable rather than limit the invention. The scope of the invention supported by the present disclosure should be construed within the scope of what it teaches to those skilled in the art. This scope is defined by the following claims.
