The present invention relates generally to tents, and more particularly to tent construction.
Tents are portable structures made of lightweight, often waterproof, fabrics. Typically, a tent is a collapsible shelter of polyester or other material stretched over and supported by a frame, such as one or more poles. Tents are used for camping outdoors, or as temporary structures. Tents come in a variety of shapes, including dome and cabin style tents.
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, a hinged door is provided for a tent. The hinged tent door in one embodiment includes a frame for supporting the outer edges of the door. The door is thus supported as a structure, and is hinged to the tent, much like the doorway of a house.
In an embodiment, the hinged tent door includes a removable frame so that the door may be folded, along with the tent, into a compact configuration for storage or transport. As an example, the frame may include one or more poles that are removably attached to the door.
In an alternate embodiment, the frame may be an air frame, in which case the frame is deflated, instead of removed, for storage. In still another embodiment, the frame may be sufficiently flexible to be folded with the tent, but yet provides sufficient structural integrity to support the door when in use.
Mechanical hinge structures may be provided that are attached to the tent and the door and that permit the door to be hinged outward from the tent. As an alternative, the fabric of the tent may serve as a hinge, or a plastic hinge may be used that serves as a living hinge. As another embodiment, a hinge may not be used, and the door may be attached so that it may rotate relative to the tent, for example by capturing a pole on the door in a sleeve on the tent. The door may also be attached for rotation relative to a pole that is attached to the tent.
In an embodiment, the opening that the door covers, i.e., the doorway, may be supported by a frame. This doorway frame may support both the attachment of the hinged door and the tent doorway. A pole, hinge, or other structure may also be provided that supports the door where it is attached to the doorway.
In an embodiment, the door may be a screen door having a frame. A flap may attach on the outside of the screen for covering the screen. The flap may attach, for example, by a zipper.
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 walls 22 and poles 24 for supporting the walls and the tent in a manner known in the art. By “walls,” for embodiments, we include portions of the tent that might typically cover the top of the tent. In accordance with an embodiment, a novel door 26 is provided that is hinged to the tent 20, for example to one of the tent walls 22. The hinged door 26 may be opened and used in much the same manner as a door for a house. Although the embodiment shown in
In the embodiment shown in
In an embodiment, the structure for the doorway includes a C-shaped pole 34 that fits into a frame upper sleeve 28, a frame lower sleeve 30, and a frame releasable sleeve 32 that runs along a side edge of the doorway. The releasable sleeve 32 may be, for example, attachable around the C-shaped pole 34 by hook and loop fasteners, a zipper, or another releasable connector. The C-shaped pole 34 may be, for example, formed from pole segments, may be a shock-corded pole, or may be a single pole bent to the C shape.
In the embodiment shown in
In the embodiment shown in the drawings, the door 26 includes a screen window 52 at an upper half of the door. This screen window includes a flap 54 that may be rolled over the screen window 52 to protect the inside of the tent 20 from the weather. If a user desires to open the window 52, this flap 54 may be rolled downward and tied or otherwise secured in a manner known in the art. In an alternate embodiment, the screen 52 and the flap 54 may cover the entire doorway so that the door 26 may serve as a screen door along its entire length.
In the embodiment shown in
In some tents, the walls 22 of the tent 20 are sloped to lean inward from bottom to top. In an embodiment, such sloped walls are provided on the tent 20. As such, the door 26 is biased towards a closed position. Thus, fasteners are not required to keep the door 26 in place, but may be helpful in keeping the door closed in windy conditions.
A hinge 60 for the door 26 is shown in
The hinges 60 provide a connection of the door 26 to the frame pole 34, and thus provide support for the door 26. Additional support may be provided, such as by attaching the hinge directly to the tent 20.
The door 102 includes a similar door sleeve 108 and door pole 110. The door pole 110 may be maintained in the door sleeve 108 in the same manner as described with the frame pole 106, or using a different technique or structure.
A hinge 112 for the door 102 is shown in
Unlike the tent 300 in
The door 502 includes a grommet 514 at a lower part of the door that attaches to a strap 516 when the door 502 is in an open position. In this manner, the door is supported outward in an awning-type manner.
In the embodiment shown in
The post sections 603 each include an L-shaped bracket. Thus, the two post sections 603 and the pole 602, when connected, define a structure in which posts 606 extend outward from each of the post sections. These posts 606 may be inserted, for example, into pockets on a side of a tent. Preferably, the pockets are arranged so that the post sections 603 place the area of the tent in tension, providing structure for one side of the frame for the doorway.
The door supported by the hinges 600 includes a frame. In the embodiment shown in the drawings, the frame consists of the poles 605 which support the outer perimeter of the door. The poles may be a single U-shaped pole or may be connected to one or more other poles so that support for the periphery of the door is provided.
The hinges 600 provide a structure that is quickly attachable to a tent and that provides a hinged door or window for the tent. The posts 606 may be removed from the pockets of the tent to remove the door and allow compact folding of the tent.
A similar hinge 700 may be provided at a lower end of the door. Thus, the two hinges 700 provide support for the doorway and a hingeable door for the doorframe. In an alternate embodiment, the hinge 700 may be used with only a single socket in the rotating section 704, and the base section 702 may be sewn or otherwise connected directly to the tent.
The hinge 800 does not flex or provide a hinging function, but instead maintains the poles 806, 808 in perpendicular alignment with one another. Thus, the pole 808 may be rotatingly received in a sleeve, and locked for position in that sleeve by attachment of the hinges 800 to opposite ends. The poles 806 may provide structure for the door. Thus, a door supported by the hinges 800 may rotate about the pole 808 and may be supported by the poles 806.
A vertical pole 856 extends between the two rings 852. The vertical pole 856 includes ferrules 858 on both ends, and a hook 860 attached to the ferrules. The hook 860 hooks around the ring 852, and the connection of the vertical pole 856 to the two rings 852 provides vertical separation of, and support for, the hinge structure 850.
A C-shaped pole 870 is provided for support of an outer perimeter of a door. This C-shaped door pole 870 includes ferrules 872 at its ends, and hooks 874 attached to the ferrules. The hooks 874 loop into the rings 852. The round cross section of the portion of the ring 852 that connects to the hooks 874 permits the hooks, and therefore the C-shaped frame 870, to rotate relative to a doorway for a tent to which the hinge structure 850 is attached.
In the embodiment shown in the drawing, a C-shaped door pole 910 is provided to support the outer perimeter of a door. Ferrules 912 are connected to both ends of the C-shaped door pole 910. C-shaped flexible clips 914 are connected to the ferrules 912. These C-shaped clips clip onto the vertical 906, and are free to rotate around the pole. In this manner, a door connected to the hinge system 900 is hingeable. In an alternate embodiment, the C-shaped clips 914 lock on to the vertical pole 906, and the pole rotates with the C-shaped door pole 910.
Similarly, a pair of air frames 960, 962 having valves 970, 972, respectively, may be provided for supporting the doorway 954. In the embodiment shown in the drawings, when the door 952 is closed over the doorway 954, the air frame 956 for the door fits between the two air frames 960, 962 for the doorway 954. Although the embodiment in
If desired, air frames may be utilized to structurally support other parts of a door, window, or opening. In addition to the perimeter support shown in the drawings, a door may be supported, for example, at intermediate locations along the door.
In another embodiment, the frame for a door or window may be foldable. In such an embodiment, the frame may be permanently sewn to the tent and is flexible enough to be folded along with the tent. This type of frame is often used in collapsible fabric laundry baskets, foldable fabric hats, and foldable fabric sun shades.
Other variations are possible. For example, the poles and other structures described herein may be used on a window, allowing the window to be hinged open, or to be used as an awning. In addition, a very large door may be provided on the back or side of the tent, similar to the door 502 in
The door 502 may be supported in a way other than the strap 516. For example, a pole or other structure may be used for support.
Embodiments of the doors described herein are fully supported about their perimeters during use, for example by poles, but the support structure for most of the doors may be removed so that the door may be folded with the tent into a compact storage configuration. In addition, the poles or other supporting structure for the doors may be broken down for efficient storage and transport. However, the perimeter support on the doors permits the doors to have a form and to hinge outward from the tent.
The doors of the invention may be used for closable openings other than windows and doors, including pet doors, pet flaps, tent or shelter vents, and skylights.
Other variations are within the spirit of the present invention. Thus, while the invention is susceptible to various modifications and alternative constructions, a certain illustrated embodiment thereof is shown in the drawings and has been described above in detail.
