Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problems: if a low-pressure chamber is installed in the open air, rainwater strikes a casing to cause noises at a rainfall; the casing is heated by direct sunlight and a person entering the low-pressure chamber cannot repress displeasure such as sultriness by radiation heat transfer from the casing for the duration of sunshine, and therefore the indoor installation of the low-pressure chamber is obliged to install indoors; and moreover, if the low-pressure chamber is installed in a flat way, costs for the land increases in a high land price area. <P>SOLUTION: In the low-pressure chamber (1) composed of a low-pressure chamber casing (2) which can bear low pressure and a pressure control mechanism (3) for controlling pressure inside the low-pressure chamber casing (2), the low-pressure chamber (1) can be installed in the open air by establishing a cover (7), which in turn interrupts a rain sound and the direct sunlight, around the low-pressure chamber casing (2) and further, the low-pressure chamber casing (2) is installed inside a stand (8) which can be laminated, or the low-pressure chamber (1) can be multistage laminated by establishing a supporting metal fitting (10) in which the low-pressure chamber (1) can be laminated, in the upper part of the low-pressure chamber casing (2). <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

The present invention relates to a low-pressure chamber for realizing a high-altitude atmospheric pressure environment on a flat ground.

In recent years, research on human physiological significance in high altitude environments has become active. Here, the highland means a low oxygen partial pressure environment. For example, when the atmospheric pressure is 1 atm on a flat ground, the altitudes are 0.80 atm and 0.74 atm at altitudes of 1800 m and 2400 m, respectively. And it is reported that if you continue training at high altitudes, you are doing well in long distance events and marathons. For those who do not exercise on a daily basis, staying at high altitudes can cause normal stress in physiological functions such as cardiopulmonary function. Improvements in functions and the like are expected to improve the efficiency of intracellular energy metabolism.

Therefore, an exercise airtight room (for example, see Patent Document 1) that exercises the body by using atmospheric pressure, or decompression that enables highland training on flat ground instead of actual highland training performed on high altitude land. Training facilities (for example, see Patent Document 2), decompression facilities where athletes can stay for a long time (for example, see Patent Document 3), and exercise large-scale decompression training facilities installed underground or semi-underground (for example, patents) References 4 and 5) have been proposed respectively, but these all relate to the structure of a large-scale low-pressure chamber on the premise of movement.

Furthermore, although the decompression training facility (for example, refer patent document 6) which proposed the pseudo high-altitude training is proposed, it is related with the structure of the large-scale low-pressure room on the assumption that these also move.

Conventionally, low pressure chambers have been made of steel plates with excellent mechanical strength to ensure the strength to withstand decompression. However, when such low pressure chambers are installed outdoors, rainwater hits the housing and makes noise when it rains. When the sun is shining, the casing is heated by direct sunlight, and radiant heat from the casing inevitably prohibits the person entering the low-pressure chamber from feeling uncomfortable, such as heat, and is forced to install the low-pressure chamber indoors. In addition, if the low-pressure chamber is installed in a plane, there is a problem in the high land price region because of the cost of site procurement. Therefore, the problem to be solved by the present invention is to eliminate the discomfort of the low-pressure room occupants in the outdoor installation of the low-pressure chamber and to effectively use the site where the low-pressure chamber is installed.

In order to solve the above-mentioned problems, the invention of claim 1 includes a low-pressure chamber housing (2) capable of withstanding a low pressure and a pressure control mechanism (3) for controlling the pressure inside the low-pressure chamber housing (2). In the low-pressure chamber (1) to be constructed, the low-pressure chamber (1) is provided with a covering (7) having a function capable of blocking rain sound and direct sunlight around the low-pressure chamber casing (2). It is an outdoor installation type low-pressure chamber that can be installed outdoors.

According to the invention of claim 2, the low pressure chamber casing (2) is installed inside the gantry (8) having a stackable function, or the low pressure chamber (1) is stacked on the upper portion of the low pressure chamber casing (2). The outdoor-installed low-pressure chamber according to claim 1, wherein the low-pressure chamber (1) can be stacked in multiple stages by providing support metal fittings (10a) and (10b) having possible functions.

According to the present invention, the low-pressure chamber can solve the problem of noise caused by rainwater during rain and the problem of heating the casing due to direct sunlight during sunshine, and can be freely installed indoors or outdoors. In addition, the multi-layer stacking of low-pressure chambers can achieve a high volumetric efficiency of low-pressure chamber installation even in high land prices, so it has a great effect on the effective use of land.

The low-pressure chamber housing (2) is installed inside the gantry (8) having a stackable function, or the low-pressure chamber (1) is supported on the upper portion of the low-pressure chamber housing (2). By providing the metal fittings (10a) and (10b), the low pressure chamber (1) can be stacked in multiple stages.

Conventionally, low pressure chambers have been made of steel plates with excellent mechanical strength to ensure the strength to withstand decompression. However, when such low pressure chambers are installed outdoors, rainwater hits the housing and makes noise when it rains. When the sun is shining, the casing is heated by direct sunlight, and radiant heat from the casing inevitably prohibits the person entering the low-pressure chamber from feeling uncomfortable, such as heat, and is forced to install the low-pressure chamber indoors. In addition, when the low-pressure chamber is installed flat, there is a problem in the high land price area because of the cost of site procurement. However, according to the present invention, there is a problem of noise caused by rain water during rain and a problem of heating the case due to direct sunlight during sunlight Can be fixed anywhere, indoors or outdoors. In addition, the multi-layer stacking of low-pressure chambers can achieve high volumetric efficiency of low-pressure chamber installation even in high land price areas, so it has a tremendous effect on the effective use of land in relaxation business by low-pressure chamber service shops.
