CROSS-REFERENCE TO RELATED APPLICATION

This application claims all benefits of Korean Patent Application No. 10-2005-65383, filed on Jul. 19, 2005 in the Korean Intellectual Property Office, the disclosures of which is incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a climbing or camping tent, and more particularly to a tent having improved windproof and ventilation abilities.

2. Background of the Related Art

In general, a tent forms a dome shape having a certain volume made by assembling waterproof fabric and a plurality of tent poles, so that it provides a user with a space in which the user can temporarily reside out of doors during the mountain climbing or camping.

As shown in FIG. 1, a general tent forms a dome shape having a certain volume made by allowing a main body 1 comprised of waterproof fabric to be expanded in all directions by a plurality of tent poles 2 having flexibility and rigidity. The tent pole is inserted into sleeves 2 formed to extend along an outer ridgeline of the main body 1 or a plurality of clips (not shown) formed along an outer ridgeline of the main body 1 at an interval. When both ends of the tent poles are respectively fixed at edges of a lower portion of the main body 1 opposing to each other under state that the tent poles are bended into an arch shape, the tent poles stretch the main body 1 in all directions so that the main body is tightly unfolded by an elastic restoring force.

However, according to the tent of the prior art, as shown in FIG. 2, when a strong wind blows from a side, the tent pole 3 facing toward the wind is inwardly bended, thereby causing a shape of the tent to be deformed.

In addition, since the tent has generally poor ventilation ability due to the structure thereof, when it is used out of doors, it gets damp in the tent at night (dew condensation phenomenon) and a temperature is rapidly increased in the tent during the daytime.

In order to improve the ventilation ability of the tent, it is necessary to form a proper air passage in the tent so that the air can flow vertically from a bottom region to an upper region in the tent by a stack effect to ventilate the inside of the tent. However, according to the tent of the prior art, since a ventilation window is mainly formed at a side portion of the main body 1 considering a problem of rainwater infiltration, the stack effect cannot be obtained.

SUMMARY OF THE INVENTION

Accordingly, the present invention has been made to solve the above problems. An object of the present invention is to provide a tent having improved windproof and ventilation abilities.

In order to achieve the above object, there is provided a tent comprising at least one main pole fixed to a ground with being bended into an arch shape so as to constitute a frame of the tent, a main body made of waterproof fabric and expanded by the main pole to form a dome shape having a certain volume, and a wind screen provided to the highest top portion of the main body so as to extend while approximately forming a horizontality with the ground and capable of resisting wind flowing along an outer surface of the main body.

According to the tent of the invention, even when a strong wind blows, it is possible to maintain an original shape of the tent without any deformation because a side of the tent is raised due to the wind screen.

According to an embodiment of the invention, the wind screen may be extended into front and rear of the main pole to form a tunnel shape. Specifically, the wind screen may comprise at least one sub-pole provided to the highest top portion of the main pole so as to intersect the main pole while approximately forming a horizontality with the ground, and screen fabric having both ends to be fixed to the outer surface of the main body and protruding from the outer surface of the main body into the tunnel shape when a central portion of the screen fabric is stretched by the sub-pole.

In addition, according to an embodiment of the invention, the tent may further comprise an upper ventilation window formed at a lower side of the wind screen of an upper portion of the main body and a lower ventilation window formed at a lower portion of the main body. In this case, the air in the main body flows vertically from the lower ventilation window toward the upper ventilation window, thereby ventilating the inside of the tent. Like this, as the air flows vertically in the tent, it is possible to obtain a stack effect.

In addition, according to another aspect of the invention, there is provided a tent comprising at least one main pole fixed to a ground with being bended into an arch shape so as to constitute a frame of the tent; a main body comprised of waterproof fabric and expanded by the main pole to form a dome shape having a predetermined volume; a fly covering the main body; and a wind screen provided to the highest top portion of the fly so as to extend while approximately forming a horizontality with the ground and capable of resisting wind flowing along an outer surface of the fly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

As shown in FIG. 3, a tent according to the first embodiment of the invention has a main body 10 consisting of a plurality of main poles 21, 22 constituting a frame of the tent and having flexibility and rigidity, and waterproof fabric to be expanded into a dome shape having a certain volume by the main poles 21, 22. A plurality of clips 11 are provided to an outer surface of the main body 10 along a ridgeline thereof at an interval. The main poles 21, 22 are bended into an arch shape with being inserted into the clips 11 and fixed to the ground at its both ends, thereby expanding the main body 10 into a dome shape.

The highest top portion of the main body 10 is provided with a wind screen 30 for resisting wind flowing along the outer surface of the main body 10 to maintain the shape of the main body 10 even when a strong wind blows.

The wind screen 30 has a sub-pole 31 provided to intersect the main pole so that it is approximately parallel to the ground at the highest top portion of the main pole 21, which is located at a central portion of the main body 10, and screen fabric having both ends to be fixed to the outer surface of the main body 10 and protruding from the outer surface of the main body 10 into a tunnel shape when a central portion of the screen fabric is stretched by the sub-pole 31.

In other words, as shown in FIG. 4, the sub-pole 31 having a radius of curvature larger than that of the outer surface of the main body 10 is bended to stretch the screen fabric 32, so that the wind screen 30 forms the tunnel shape extending into the front and rear of the main pole 21 to be parallel to the ground at the highest top of the main body 10.

When a strong wind blows from a side of the tent, a front side 13 or rear side 14 of the main body 10 is bended into the tent due to an influence of the wind, as shown with a dash-dot-dot line in FIG. 4. At this time, since the front side 13 and the rear side 14 are formed to be inclined, the wind rises to the upper region of the main body 10 along the front side 13 or rear side 14 to strike against the wind screen 30. As the risen wind strikes against the wind screen 30, the wind screen 30 is upwardly expanded, so that the front side 13 or rear side 14 having been bended inwardly is raised outwardly on the whole to recover its original shape. Accordingly, the tent according to the present invention has an excellent windproof ability allowing the tent not to be easily deformed even when a strong wind blows.

Referring to FIG. 3 again, upper and lower portions of the front side 13 of the main body 10 are formed with an upper ventilation window 41 and a lower ventilation window 42 for ventilating an inside of the tent, respectively.

The upper ventilation window 41 is formed at the upper portion of the main body in the wind screen 30. Since the wind screen 30 serves as an awning, there is no worry that rainwater flows in the tent via the upper ventilation window 41.

The lower ventilation window 42 is formed perpendicularly to the ground at a lower inside of the front side 13 of the main body. By doing so, it is possible to prevent the rainwater from flowing in the tent via the lower ventilation window 42. The front side 13 of the main body is set up such that a lower end thereof is spaced from the ground at an interval. Thereby, the outside air can flow in the tent through the lower ventilation window 42 via a space formed between the front side 13 of the main body and the ground.

As shown in FIG. 4, the outside air flows in the main body 10 through the lower ventilation window 42 and the air in the main body 10 is discharged to the exterior through the upper ventilation window 41. In other words, according to the tent of the present invention, since the air flows vertically from the lower ventilation window 42 toward the upper ventilation window 41, a stack effect is expressed, so that good ventilation ability can be obtained.

In the embodiment shown in FIGS. 3 and 4, it is shown the ventilation windows 41, 42 formed at the front side 13 of the main body 10 only. However, it should be noted that the invention is not limited thereto. That is, the ventilation windows may be formed at upper and lower portions of the rear side 14 of the main body 10 and both at the front side 13 and the rear side 14.

In addition, in the embodiment shown in FIGS. 3 and 4, as a structure of the wind screen 30, it is shown that the screen fabric 32 is upwardly stretched by the single sub-pole 31 to form the tunnel shape. However, the structure of the wind screen 30 is not limited thereto and various modifications thereof can be made.

FIG. 5 shows a tent according to the second embodiment of the invention.

As shown in FIG. 5, the tent according to this embodiment has the main pole 21 transversely crossing over the main body 10 of the tent, and a pair of sub-poles 31 equipped side by side at an interval to the highest top portion of the main pole 21. In this embodiment, the screen fabric 32 is upwardly stretched by the pair of sub-poles 31, so that the wind screen 30 forms a tunnel shape having a width larger than that of the wind screen 30 shown in FIG. 3.

In the mean time, according to this embodiment, the tent is formed with a ventilation window 43 at an upper portion of the rear side 14 of the main body 10 and an entrance 15 having a size over a total area at the front side 13, so that it is possible to obtain a better ventilation ability than the embodiment shown in FIG. 3.

FIGS. 6 and 7 show a tent according to the third embodiment of the invention.

As shown in FIG. 6, the tent according to this embodiment comprises a fly 40 to be set up over the main body 10. The main poles 21, 22 constitute a frame of the main body 10 and support the fly 40.

Meanwhile, the wind screen 30 is formed on the top of the fly 40. Specifically, the screen fabric 32 formed on the highest top portion of the fly 40 is supported by the sub-pole 31, so that the wind screen 30 forms a tunnel shape. Both ends of the screen fabric 32 are fixed to the top outer surface of the fly 40 and the sub-pole 31 is connected to a central portion of the fabric with being bended to have a radius of curvature larger than that of the main body 10, so that the screen fabric forms a tunnel shape parallel to the ground.

As shown in FIG. 7, the ventilation window 42 for ventilating the inside of the tent is formed at the upper portion of the fly 40. The ventilation window 40 is formed to be located adjacent to the highest top portion of the tent and the wind screen 30 is extended beyond the ventilation window 43 toward the ground so that the ventilation window 42 is not exposed to the exterior.

In this embodiment, the fly 40 covering the outer surface of the main body 10 is formed with the wind screen 30 and the ventilation window 42, so that it is possible to prevent the rainwater from entering the tent without doubt as well as to obtain good ventilation ability.

FIG. 8 shows a tent according to the fourth embodiment of the invention.

The tent according to the embodiment shown in FIG. 8 has such structure that the wind screens 30, 30′ are formed on the top of the fly 40 covering the main body 10, as the tent shown in FIG. 6. However, the tent according to the embodiment shown in FIG. 8 is different from the tent shown in FIG. 6 in that the fly 40 is set up to extend into the front and rear of the main body 10.

In the tent shown in FIG. 8, a pair of fly poles 51, 52 is provided to the front and rear of the main body 10 so as to maintain the shape of the fly 40. The fly poles 51, 52 allow the fly 40 to be extended into the front and rear of the main body 10 by stretching the fly 40 from the outer side of the fly 40.

The sub-poles 31, 31′ for forming the wind screen 30, 30′ are provided to intersect the fly poles 51, 52 at the highest top portion of the fly poles 51, 52. Accordingly, the wind screens 30, 30′ are formed at the front and rear of the fly 40.

As described above, according to the invention, the wind screen resisting the wind flowing along the outer surface of the main body is provided at the highest top portion of the tent main body. Accordingly, since the side of the tent is raised due to the wind screen even when the strong wind blows, it is possible to maintain the original shape of the tent. That is, it is possible to embody a tent having excellent windproof ability.

Further, according to the invention, the ventilation windows are provided to the inside of the wind screen at the upper portion of the main body and to the lower portion of the main body, respectively. Accordingly, since the air can flow vertically in the tent and a stack effect can be thus obtained, it is possible to embody a tent having excellent ventilation ability.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
