Tent fabric and tents

Abstract

To provide a tent fabric and tent that use a tent fabric with one-way visibility at the tent entrance, making it difficult to see inside from the outside, while conversely making it easy to see outside from the inside, and also providing ventilation and waterproofing for the tent. [Solution] A tent fabric 11 is provided with numerous circular holes 12a and 12b aligned in a straight line in both the vertical and horizontal directions, with a vertical hole pitch 13a of 3.2 mm and a horizontal hole pitch 13b of 3.00 mm, and each hole diameter of 0.8 to 2.0 mm. Furthermore, a black coating 20a is applied to the interior side of the tent fabric, and this fabric is used for the tent entrance. As a result, in environments where the external illumination is higher than the internal illumination, it is difficult to see inside from the outside, while the outside can be seen through from the inside, and the surface tension of the minute circular holes prevents rainwater from entering, ensuring breathability and waterproofing. This fabric can be applied not only to tent entrances but also to windows, etc., achieving both comfort and privacy for occupants inside the tent.

Description

Technical Field

[0001] This invention relates to tent fabrics and tents.

Background Art

[0002] In recent years, camping has become popular as a way to spend leisure time. An essential item for this camping is a tent. Regarding the tent fabric used for this tent, conventionally, mesh fabrics have been widely adopted for the tent fabric used for openings corresponding to the entrance / exit and window parts of the tent in order to ensure breathability. However, mesh fabrics have the problem that while it is possible to see through from the inside to the outside of the tent, at the same time, it is also possible to see through from the outside to the inside of the tent.

[0003] Therefore, for example, a tent fabric with one-way visibility as disclosed in Utility Model Registration No. 3253802 (Patent Document 1) has been proposed. According to this, when used for a tent, in an environmental condition where the external illuminance is high and the internal illuminance is low, it exhibits a one-way visibility effect where the inside of the tent can be seen through from the inside to the outside, but it is difficult to see from the outside to the inside, and a certain degree of privacy inside the tent can be ensured.

Summary of the Invention

Problems to be Solved by the Invention

[0005] This invention aims to provide a tent fabric and a tent using it that differ from conventional tent fabrics in the arrangement of perforations, and which can be used particularly in tent entrances and windows to ensure ventilation and waterproofing inside the tent, while allowing a clear view from the inside of the tent to the outside, but making it difficult to see inside from the outside, thereby ensuring comfort and privacy for occupants. [Means for solving the problem]

[0006] The tent fabric of this invention has numerous circular holes arranged in a straight line in both the vertical and horizontal directions, with a vertical hole pitch of 3.2 mm and a horizontal hole pitch of 3.00 mm, and each hole diameter of 0.8 to 2.0 mm.

[0007] Furthermore, the tent of this invention has the interior side of the tent fabric coated in black, and the tent fabric is used for the opening of the tent's entrance. [Effects of the Invention]

[0008] According to the tent fabric of this invention, by providing numerous circular holes in the fabric so as to be aligned in a straight line in both the vertical and horizontal directions, the fabric is given breathability and light transmission in one direction, and by making the circular holes small, even if rainwater is applied, it will not pass through the holes due to the surface tension of the water (unless it is heavy rain accompanied by strong winds), thus providing waterproofing as well.

[0009] Furthermore, by using the tent fabric of this invention for the entrances and windows of a tent, the numerous circular holes make it difficult to see from the brightly lit outside of the tent to see into the relatively dimly lit inside of the tent, thus maintaining privacy. Conversely, it is possible to see the outside from inside the tent through the tent fabric, ensuring a sense of openness.

[0010] Furthermore, according to the tent of this invention, by coating the interior side of the tent fabric with black, the inside of the tent can be kept relatively dark, while by using the same tent fabric at the entrance of the tent body, the brighter outside of the tent can be seen clearly through the tent fabric at the entrance, and conversely, it is made difficult to see inside the tent from the outside, thus maintaining privacy inside the tent, while also ensuring breathability and waterproofing, resulting in a comfortable living environment. [Brief explanation of the drawing]

[Figure 2] Front view and partial enlarged view of the tent fabric according to the above embodiment. [Figure 3] A perspective view of the tent according to the above embodiment when it is installed outdoors. [Figure 4] This is a perspective view showing what the outside looks like when the tent of the above embodiment is set up outdoors, and viewed from inside the tent through the tent fabric at the entrance. [Modes for carrying out the invention]

[0012] The embodiments of this invention will be described in detail below with reference to the drawings.

[0013] Figure 1 shows the overall structure of a tent 1 using tent fabric 10 according to one embodiment. While the tent 1 in this embodiment is dome-shaped, the tent's form is not particularly limited and may be lodge-shaped. The size is also arbitrary.

[0014] The tent fabric 10 of this embodiment is used at the entrance 2 of the tent 1, allowing users to enter and exit through this entrance 2. The same fabric can also be used at the window openings of the tent 1 where ventilation is required (not shown). The material of the fabric 11 of the tent fabric 10 can be either natural fibers or synthetic fibers, which are commonly used for tent fabrics. It may also be made of a different material from other parts of the tent 1.

[0015] As shown in FIGS. 2(a) and 2(b), a large number of circular through-holes 12a and 12b are provided in the fabric 11 so as to be aligned in a straight line in both the vertical and horizontal directions. The hole pitch 13a of the vertical rows of the circular through-holes 12a and 12b is 3.2 mm, and the hole pitch 13b of the horizontal rows is 3.00 mm. Each hole diameter is 0.8 to 2.0 mm.

[0016] Here, the reason why the hole diameter of each circular through-hole 12a and 12b is in the range of 0.8 to 2.0 mm is that when the hole diameter is less than 0.8 mm, the ventilation volume and the transparency from the inside are likely to be insufficient, and it is also difficult to form the holes. On the other hand, when the hole diameter exceeds 2.0 mm, it is difficult to obtain the waterproof effect due to the surface tension described later, and the inside of the tent 1 can be easily seen from the outside, making it difficult to ensure privacy. Also, the reason for making the hole pitch 13a (3.2 mm) of the vertical rows slightly larger than the hole pitch 13b (3.00 mm) of the horizontal rows is to arrange a large number of circular through-holes 12a and 12b neatly according to the difference in the density of the warp and weft of the fabric 11, and to ensure an aperture ratio that can achieve both air permeability and one-way light transmittance while suppressing a decrease in the strength of the fabric 11.

[0017] The whole tent 1 is stretched in a dome shape through an elastic frame 21 on an opaque tent cloth 20. The tent cloth 20 is provided with a black coat 20a on the inner surface to have light-shielding properties.

[0018] As shown in FIG. 3, in the tent 1 assembled in this way, it is possible to see through the bright outside from inside the tent 1 through the entrance / exit 2 provided with the tent fabric 10 of the embodiment.

[0019] As shown in FIG. 4, from the outside of the tent 1, it is not possible to peek inside the tent 1 even through the tent fabric 10 at the entrance / exit 2. However, air permeability is ensured. Also, since there is surface tension in rainwater and the circular through-holes 12a and 12b have a small diameter, rainwater does not enter the inside of the tent 1 through these circular through-holes 12a and 12b.
