Description

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

In recent years, research on the physiological significance of people 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 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. Also, for those who do not exercise regularly, staying at high altitude causes normal stress of physiological functions such as cardiopulmonary function, and if it is the same life load as flat land, the high altitude is relatively higher, oxygen transport Improvements in functions and the like are expected to increase 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 large-scale exercise decompression training facilities installed in the basement 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, when trying to install a low-pressure chamber in a corner of an apartment, condominium or other small house, a rectangular parallelepiped low-pressure chamber has been forced to have a hexahedral plane structure, but such a hexahedral plane configuration. In order to ensure pressure resistance, each plane has a rib structure in which ribs are arranged vertically and horizontally on one side or both sides of a flat plate, and is large and fixed. Therefore, in the production of a low-pressure chamber using a hexahedron plane structure, rib material preparation, rib welding, and rib painting are indispensable, and the rectangular parallelepiped low-pressure chamber has a limit in reducing manufacturing costs. .

The present invention has a conventional planar configuration in which a pair of casings each having a casing flange and having a recess therein are arranged facing each other at the outer peripheral end of the casing. It eliminates the need for flat plate ribs, eliminates the need for rib material, eliminates the need for rib welding, and provides a safety device for opening and closing the housing of a low-cost low-pressure chamber that eliminates the need for rib coating. is there.

In order to solve the above-mentioned problems, the invention of claim 1 is characterized in that two housings (2) and (4) made of a pressure vessel end plate having recesses face each other so that the recesses face each other, and a living space is formed inside the housing. (1) and seats (22) and (23) are provided, and a packing (6) is arranged between the butted portions of the outer peripheral ends of the casings (2) and (4) so as to be openable and closable. In the room, the seats (22), (23) are seated sensors (24a), (24b) and the two-hand operation push button switches (25a), (25b) on both sides of the seats (22), (23), respectively. , (25c), (25d), and when all the people seated in the seats (22), (23) operate the push button switches (25a), (25b), (25c), (25d) with both hands Double safety that can only close the housing (2), (4) Characterized in that it is a housing closing safety device of the low-pressure chamber provided with a location.

The invention of claim 2 is a speaker (26) or a display provided in the housing space (1) inside the housing (2), (4) before and during the opening and closing of the housing (2), (4). 2. The low pressure chamber according to claim 1, wherein the television (27) provides guidance to the low pressure chamber occupant that the casing (2), (4) is opened or closed by voice or video or both means. This is a case opening and closing safety device.

By this device, the safety of the low-pressure room occupants can be completely secured, and the product value is further enhanced by the sensory effect of boarding the space shuttle, as the registered name of the low-pressure room “Shuttle Keifu”. It has risen.

FIG. 1 is a front view showing an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1, and FIG. 3 is a cross-sectional view taken along the line BB of FIG.

A housing space (1) and seats (22) and (23) are provided inside the casing with the recesses of the two casings (2) and (4) made of pressure vessel end plates having recesses facing each other. In the low pressure chamber in which the packing (6) is arranged between the butted portions of the outer peripheral end portions of the casings (2) and (4) so as to be able to be opened and closed, the seats (22) and (23) are respectively Two-hand operation push button switches (25a), (25b), (25c), (25d) are provided on both sides of the seating sensors (24a), (24b) and the seats (22), (23), respectively. 22) All the members seated in (23) can close the casings (2) and (4) only when the push button switches (25a), (25b), (25c) and (25d) are operated with both hands. A double safety device was installed.

Another embodiment will be described.
Before and during the opening and closing of the housings (2) and (4), the speaker (26) or the display television (27) provided in the living space (1) inside the housings (2) and (4) Alternatively, it is possible to provide guidance to the person entering the low-pressure chamber that the casings (2) and (4) are starting or opening / closing by means of video or both means.

The conventional low-pressure chamber required an airtight door to enter the low-pressure chamber. However, in the low-pressure chamber of the present invention, the housing itself opens and closes, and safety is provided to prevent accidents caused by being caught when opening and closing. Since the apparatus is provided, a person entering the low pressure chamber can safely enter the low pressure chamber.

It is the front view which showed embodiment of this invention. It is sectional drawing of the AA line direction of FIG. It is sectional drawing of the BB line direction of FIG.
