The present invention generally relates to tents and shelters, and more particularly to tent and shelter construction.
Camping is a popular recreational activity enjoyed by many. Some people camp so that they may enjoy the outdoors, and others use camping as an inexpensive alternative to staying in a hotel.
Typically, campers sleep in a tent while camping. Tents are portable shelters made of lightweight, often waterproof, fabrics. Typically, the fabric is stretched over and sustained by a frame. Tents are used for camping outdoors or as temporary structures, and come in a variety of shapes and sizes. The most popular shape is the dome, or free standing, model. This model is easy to set up and does not require support from tree limbs or other objects.
Another structure that is often used while camping is a shelter. In general, a shelter is a structure, typically a frame with poles, that includes a covering or canopy that provides protection from the rain, insects, and/or the sun. For camping, a shelter is typically made of fabric and foldable poles so that the shelter may be folded into a compact configuration for transport and storage. The shelter may or may not have walls, such as screen walls. The shelter may be, for example, set up over a picnic area, used adjacent to a tent as a storage area, configured to serve as protection from the rain, or used as a screened area to avoid insects.
The advent of new waterproof materials typically prevents a shelter canopy as well as a rain fly for a tent from leaking. Thus, rain flies and shelter canopies typically work well to shelter a tent or other items underneath the covering. However, one problem with the use of such coverings is that water draining off of a rain fly or a shelter canopy may drip in undesirable areas, such as at a tent door or at tent windows. In addition, a hard rain may cause a large amount of water to flow off of a covering and may cause considerable splashing or splatter, especially for shelters, which typically have canopies that are spaced higher from the ground than a tent rain fly.
The following presents a simplified summary of some embodiments of the invention in order to provide a basic understanding of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified form as a prelude to the-more detailed description that is presented later.
In accordance with an embodiment of the invention, a gutter and downspout system is provided that may be used with a tent, shelter, or other fabric structure. As one example, the gutter may be aligned along a rain fly edge to direct water away from the tent door or tent windows. After the rainwater is directed the proper distance to clear the tent door and/or windows, the water can fall from the rain fly to the ground. Alternatively, in accordance with an aspect of the invention, the rainwater may be directed via a downspout to the ground. Thus, a camper can enter or exit the tent through the door without the water dripping on the camper. In addition, windows may be left partially open during a rain shower without the rainwater runoff entering the tent through the open window(s). Also, rainwater flow off a shelter may be controlled and/or directed.
In accordance with an embodiment of the invention, the gutter is formed of a flexible material that is sewn to the rain fly or to the canopy. In accordance with another embodiment of the invention, the flexible material is positioned inside the trim fabric for the rain fly or canopy. In accordance with yet another embodiment of the invention, the flexible material is sufficiently flexible to allow compact packing of the rain fly or canopy when not in use. The flexible material may, for example, be formed of closed cell polyethylene or another flexible tube extrusion. The gutter may be aligned along edges of the rain fly or shelter canopy. Alternatively, if a shortened version of a gutter is used, then the shortened version of the gutter may be sufficient to allow rainwater runoff to miss a tent door and/or windows. In accordance with an embodiment of the invention, the gutter material may also be positioned at locations other than at the edge of the rain fly or shelter canopy.
In accordance with an embodiment of the invention, a downspout may be provided that enhances water control of rainwater runoff. The downspout may include, for example, a flexible ring at an upper portion connected to an elongate waterproof fabric tube. The end of the tube may be arranged and directed as wanted. The attachment of the downspout to a rain fly or shelter canopy may be permanent or removable. The downspout directs rainwater runoff completely away from the tent or shelter area so that pooling or accumulation of water under or around the tent or shelter is eliminated.
Other features of the invention will become apparent from the following detailed description when taken in conjunction with the drawings, in which:
In the following description, various embodiments of the present invention will be described. For purposes of explanation, specific configurations and details are set forth in order to provide a thorough understanding of the embodiments. However, it will also be apparent to one skilled in the art that the present invention may be practiced without the specific details. Furthermore, well-known features may be omitted or simplified in order not to obscure the embodiment being described.
Referring now to the drawings, in which like reference numerals represent like parts throughout the several views,
The tent 20 includes a rain fly 22 covering a top portion of the tent 20. The tent 20 also includes a door 24 and windows 26 and 28 on sides of the tent 20. In the embodiment shown, the rain fly 22 extends out beyond the door 24 and the windows 26, 28. However, embodiments of the present invention can be used with tents having a different structure.
The rain fly 22 shown in the drawings includes a top 30, and side edges 32, 34, and 36. In the drawings, the side edge 32 is to the right, the side edge 34 is to the front, and the side edge 36 is to the left.
In accordance with an embodiment of the invention, a gutter or gutters may be provided on the rain fly 22 or on a rain fly for another tent. In fact, although the embodiments described are discussed with reference to the rain fly 22 for the tent 20, embodiments of the invention may be used for any covering in which it is desired to direct rainwater runoff, including, but not limited to, canopies, shelters, and tarpaulins.
In the embodiment shown, a gutter is not included on the right side edge 32 of the rain fly 22. However, a full gutter 40 extends along the entire length of the front side edge 34. A partial gutter 42 extends a portion of the length of the left side edge 36. The full gutter 40 redirects water heading toward the front side edge 34 to corners 46, 48 of the rain fly 22. The partial gutter 42 directs water away from the window 26, but because it does not extend to the corner 48 or an opposite corner 50, the partial gutter 42 only provides partial redirecting of water from the side edge 36.
In the embodiment shown in
In the embodiment shown in
The trim material 56 is aligned beginning at a top end 60 along the top 52 of the rain fly 22. The trim material 56 then extends in a loop 62 around the bead 58 and then is overlapped over the top end 60 in an overlap section 64. The trim material 56 then wraps around under the bottom 54 of the rain fly 22 and terminates at a bottom end 66.
In the embodiment shown, the trim material 56 may be glued, sewn, or otherwise attached to the top 52 and/or bottom 54 of the rain fly 22. In accordance with an embodiment of the invention, the trim material 56 is attached so that the overlap section 64 is fixed to the top end 60 so that a break 68 occurs in the trim material 56 between an attached portion of the overlap section 64 and the loop 62. This break 68 is the point at which the overlap section 64 is no longer attached to the top end 60. The top end 60 of the trim material 56 is attached to the top 52 of the rain fly 22 up to this same break 68.
Thus, in accordance with this embodiment of the invention, the loop 62 is not attached to the rain fly 22, permitting the loop 62 to move to the position shown in
If desired, the trim material 56 may be attached at a location other than at an edge of the rain fly 22. For example, in the embodiment of a tent 70 shown in
The gutters 72, 74 may be attached in a manner similar to the gutter 40 described with reference to
Returning to a description of the bead 58, the bead 58 is preferably a flexible material to allow compact packing of the rain fly 22 when not in use. As an example, the bead 58 may be a closed cell polyethylene foam extrusion, having a round cross section, or alternatively a cross section of another suitable shape. The bead 58 may also be a flexible polyvinyl chloride extruded tube. In an example of a gutter 80 shown in
As described above, the gutter system of the present invention provides a gutter geometry that resists the flow of water down a rain fly (e.g., the rain fly 22) and provides a damming effect for that water. This damming effect provides a resistance to stop the flow of water over the gutter, such as at a rain fly edge, and directs the water parallel to the gutter toward the end of the gutter which may, for example, be at a rain fly corner 46 or 48. Alternatively, if a partial gutter 42 is used, the water may be directed to the ends of the gutter which may correspond, for example, to just beyond the outer edges of the window 26. Alternatively, as also described above with reference to
In accordance with an embodiment of the invention, a downspout 100 (e.g.,
In use, water flows down the rain fly 22 and into the downspout 100. The water may be directed in this manner, for example, by the full gutter 40. Water directed into the downspout 100 flows into the open mouth formed by the flexible bead 102 and out of the end 104.
The flexible bead 102 provides an advantage in that it permits easy flow of water into the downspout 100. If desired, a downspout could be configured to not include such a flexible bead, but construction with the flexible bead 102 permits easy capture of water directed toward the downspout 100. In addition, the use of flexible material for the flexible bead 102 permits the downspout 100 to be folded into a compact configuration for storage or transport.
The downspout 100 may be attached to the rain fly 22 in a suitable manner, such as by sewing, adhesive, or another permanent attachment mechanism. Alternatively, the downspout 100 may be attached to the rain fly 22 so that the downspout 100 is removable. For example, the downspout 100 may be attached by hook and loop fasteners (not shown, but known in the art)
Although shown attached to the corners 46, 48, the downspout 100 may alternatively be used in other areas. For example, for the rain fly 22, downspouts 100 may be attached at the ends of the partial gutter 42. These downspouts 100 may have their ends 104 suitably directed either along the rain fly 22 or, if the downspout 100 is long enough, to the ground.
The end 104 of the downspout 100 may be directed so that the rainwater runoff may be directed away from a base of the tent 20 or away from a shelter, if used with a shelter. This feature aids in keeping the tent 20 dry, and may be utilized to avoid puddles in a tent or shelter area.
The present invention provides a method of controlling and directing rainwater runoff from a rain fly (e.g., the rain fly 22), a shelter, or other covering. The gutter system of the present invention directs the rainwater runoff along the gutter, for example along a rain fly edge, downward to the ends of the gutter. The ends of the gutter may be at corners of the rain fly, or at other suitable locations. The water directed to the corners or other location(s) may be allowed to fall to the ground or may be directed to run into the downspout 100. If the downspout 100 is used, the runoff water may be directed to a suitable location by directing the end toward the location.
