This application claims the benefit of Chinese Patent Application 200820101733.4 filed on Mar. 19, 2008, which is hereby incorporated by reference in its entirety.
The field of the invention relates generally to a portable structure, such as a tent, and, more particularly, to a tent having a component or structure that facilitates draining of water, such as rainwater, from the tent fabric to prevent or limit undesirable accumulation of such water on areas of the tent fabric.
In recent years, tent camping has become increasingly more popular with rapid economic development and enhancement of living standards throughout the world. Conventional tents include a tent frame, a tent fabric connected with the frame and an apron fabric connected about a lower circumference of the tent fabric such that the apron fabric encircles an outer perimeter defined by the frame. Conventional tents may not include a draining component or structure for rapidly draining rainwater collected on the tent fabric during a rain storm and, as a result, a large amount of rainwater may accumulate on the tent fabric that will impose a heavy burden on the tent fabric and/or the tent frame, such that a service life of the tent may be reduced.
In one aspect, a tent defining an interior volume and configured to facilitate draining rainwater is provided. The tent includes a frame, a tent fabric connected with the frame, and an apron fabric connected with the tent fabric. A portion of the apron fabric defines a concave cavity that extends inward with respect to the interior volume of the tent. A portion of the tent fabric is connected with the portion of the apron fabric defining the concave cavity. The portion of the tent fabric extends downward with respect to a ground plane to define a concavity in flow communication with the concave cavity to define a passage configured to drain rainwater from the tent fabric.
In another aspect, a portable structure defining an interior volume, and configured to facilitate draining rainwater, is provided. The portable structure includes a frame including a central support and a side support shorter than the central support. A roof fabric has a first edge coupled to the central support and an opposing second edge coupled to the side support. At least a portion of the roof fabric extends downward at the second edge with respect to a ground plane to define a concavity. An apron fabric is coupled to the roof fabric at a joint. The apron fabric is configured to extend toward the ground plane. A portion of the apron fabric defines a concave cavity that extends inward with respect to the interior volume of the portable structure. The concave cavity is in flow communication with the concavity to define a passage configured to drain rainwater from the roof fabric.
In a further aspect, a method is provided for making a tent configured to facilitate draining rainwater. The method includes forming a tent fabric having a first edge that is configured to couple to a first support and an opposing second edge configured to couple to a second support shorter than the first support such that, with the tent constructed to define an interior volume, at least a portion of the tent fabric extends downward at the second edge with respect to a ground plane to define a concavity. An apron fabric is coupled to the tent fabric at a joint. With the tent constructed, the apron fabric is configured to extend toward the ground plane, and a portion of the apron fabric defines a concave cavity that extends inward with respect to an interior volume of the constructed tent. The concave cavity is in flow communication with the concavity to define a passage configured to drain rainwater from the tent fabric.
This disclosure describes a portable structure, such as a tent, configured to facilitate preventing or limiting accumulation of rainwater on a roof or tent fabric. In one embodiment, the tent includes a draining component or structure to facilitate draining rainwater from the tent fabric to prevent or limit accumulation of rainwater on the tent fabric. The tent includes a tent frame, a tent fabric connected with the tent frame, and an apron fabric connected with the tent fabric at a lower circumference of the tent fabric. A portion of the apron fabric, such as a top edge portion of the apron fabric defines a concave cavity that extends inward with respect to a volume defined by the tent. A portion of the tent fabric, such as a bottom edge portion of the tent fabric at least partially coupled to the top edge portion of the apron fabric, extends downward to define a concavity. The concave cavity cooperates with or is in flow communication with the concavity to define a passage for the rainwater to move through to prevent or limit accumulation of rainwater on the tent fabric. In one embodiment, the passage is positioned within a central area of the tent fabric and the apron fabric and does not extend an entire width of the tent fabric and the apron fabric. In alternative embodiments, an alternative passage or an additional passage may be formed at one or more ends or corners of the tent fabric.

In the exemplary embodiment, tent fabric 14 and/or apron fabric 18 is connected with or coupled to a gauze or netted fabric 60. Netted fabric 60 may include any suitable material that allows rainwater to flow through netted fabric 60. In one embodiment, netted fabric 60 includes a material suitable for allowing rainwater to flow through netted fabric 60 while preventing debris, such as leaves and twigs, from flowing through netted fabric 60. As shown in
The present disclosure provides a portable structure, such as a tent or a gazebo, which defines an interior volume suitable for accommodating one or more occupants. The portable structure includes a draining component or structure configured to facilitate draining rainwater to prevent or limit undesirable accumulation of rainwater on the portable structure. The portable structure includes a frame having a central support and side supports positioned on opposing sides of the central support. Each side support is shorter than the central support. A roof fabric has a first edge coupled to the central support and an opposing second edge coupled to the side support. At least a portion of the roof fabric extends downward at the second edge with respect to a ground plane to define a concavity. An apron fabric is coupled at a top edge to the roof fabric at a joint. The apron fabric is configured to extend toward the ground plane. At least a portion of the apron fabric at the top edge defines a concave cavity that extends inward with respect to the interior volume of the portable structure. The concave cavity is in flow communication with the concavity to define a passage configured to drain rainwater from the roof fabric. In a particular embodiment, the passage is defined by a rotary arc surface having an axis outside the tent.
The top edge of the apron fabric is at least partially coupled to the second edge of the roof fabric at the joint to define the passage. In the exemplary embodiment, a connecting fabric couples the top edge of the apron fabric and/or the second edge of the roof fabric to the side support. A netted fabric has a first portion or edge coupled to the top portion of the apron fabric defining the concave cavity and an opposing second portion or edge coupled to the connecting fabric. The first portion or edge of the netted fabric is coupled transversally with a central region of the apron fabric defining the concave cavity and/or coupled transversally with a central region of the tent fabric defining the concavity such that an upper portion of the passage defined by the concavity has a first angle with respect to the connecting fabric and a lower portion of the passage defined by the concave cavity has a second angle with respect to the connecting fabric greater than the first angle. In a particular embodiment, the first angle is less than 90° and/or the second angle is an obtuse angle.
The embodiments described herein provide a portable structure, such as a tent, having a draining mechanism or structure that facilitates preventing water, such as rainwater, from accumulating on the roof or tent fabric, and therefore facilitates overcoming such noted drawbacks associated with some conventional tents.
In one embodiment, the tent includes a tent frame, a tent fabric connected with the tent frame, and an apron fabric connected to a lower circumferential or peripheral edge portion of the tent fabric. A top portion of the apron fabric defines a concave cavity that extends inward with respect to the apron fabric into an interior volume defined by the tent. A portion of the tent fabric is connected with the top portion of the apron fabric defining the concave cavity and extends downward towards a ground plane to define a concavity. This concavity cooperates with or is in flow communication with the concave cavity to define a passage for draining rainwater collected on the tent fabric to prevent or limit accumulation of rainwater on the tent fabric. In one embodiment, the apron fabric is located on an outside of the tent frame. The apron fabric is connected with a gauze or netted fabric having a bottom portion that is connected with or coupled to the top portion of the concave cavity. In a further embodiment, the passage for draining the rainwater is defined at least partially by a rotary arc surface having an axis defined outside of the tent.
The tent frame includes a central support and at least two side supports. The two side supports are located on opposite sides of the central support and have a height less than a height of the central support. A top or central portion of the tent fabric is connected with the central support, and a joint coupling the apron fabric and the tent fabric is connected with or coupled to the side support. A top of the netted fabric is also coupled to the side support.
In contrast with conventional tents, the embodiments described herein facilitate preventing or limiting an accumulation of rainwater on the tent fabric and facilitate preventing or limiting wetting of the tent frame by the rainwater. In the exemplary embodiment, the concave cavity of the apron fabric extends inward, the edge portion of the tent fabric is connected with or coupled to the top edge portion of the apron fabric defining the concave cavity and extends downward to define a concavity, and this concavity cooperates with and/or is in flow communication with the concave cavity to define a passage for the rainwater collected on the tent fabric to drain through. Therefore, the rainwater may drain off the tent fabric through the passage to prevent or limit accumulation of rainwater on the tent fabric. The bottom portion of the netted fabric is connected or coupled transversally with the apron fabric and/or the tent fabric that at least partially defines the passage for draining rainwater. The netted fabric does not prevent the drainage of rainwater, and the joint between the netted fabric and the passage may be pulled outward to be elevated to increase a rate of the rainwater drainage. In one embodiment, the passage for draining rainwater is defined by a rotary arc surface having an axis such that a relatively large amount of rainwater on the tent fabric may be drained off rapidly through the passage.
