Description

In recent years, research on the physiological significance of people in highland environments has become active. The present invention relates to a low pressure chamber for realizing a high altitude atmospheric pressure environment on a flat ground.

(Patent Document 1) Conventionally, in Japanese Patent Publication No. 2-42992, an exercise hermetic chamber, in Japanese Patent Application Laid-Open No. 8-112373, a decompression training facility assuming a pseudo high altitude training, and in Japanese Patent Application Laid-Open No. 11-336373, a decompression in which an athlete can stay for a long time In the facility, Japanese Patent No. 2919111 and Japanese Patent Laid-Open No. 2000-54666, a large-scale decompression training facility for exercise installed in the basement or semi-underground is proposed. Is related to the structure of
(Non-Patent Document 1) In addition, although a decompression training facility assuming pseudo high altitude training is proposed in Japanese Utility Model Laid-Open No. 2-118571, this also relates to the structure of a large-scale low-pressure chamber on the premise of exercise. .

The present invention relates to a structure of a low-pressure chamber that can be manufactured at a very low cost not only in a decompression training facility for athletes but also in a low-pressure chamber installed in a corner of an apartment, condominium, or other small house.

The present invention includes a flat mirror plate, a dish-shaped mirror plate, a regular semi-elliptical mirror plate, an approximate semi-ellipsoidal mirror plate, a deep dish-shaped mirror plate, a missing ball, a special dish-shaped mirror plate, a hemispherical mirror plate, a pipe cap, and a cone-shaped mirror plate. It is characterized by being a low-pressure chamber that can be manufactured at an extremely low cost, which has not been seen in the past, by comprising an eccentric conical, a bell mouth, a lifted end panel, a hat type or an expansion.

Conventionally, when trying to install a low-pressure chamber in one corner of an apartment, condominium, or other small house, a rectangular parallelepiped low-pressure chamber has a casing structure with a plane configuration called a hexahedron. In order to ensure the pressure resistance of the flat surface, a rib structure in which ribs are arranged vertically and horizontally on one side or both sides of the flat plate has to be used. Therefore, preparation of rib material, rib part welding work and rib part painting work are required, and the rectangular parallelepiped low-pressure chamber has a limit in reducing the manufacturing cost.

On the other hand, in the present invention, the casing is made of a flat mirror plate, a dish-shaped mirror plate, a regular semi-ellipsoidal-shaped mirror plate, an approximate semi-ellipsoidal-shaped mirror plate, a deep dish-shaped mirror plate, a missing ball, a special dish-shaped mirror plate, a hemispherical-shaped mirror plate, a pipe cap, Consists of a cone-shaped end plate, eccentric conical, bell mouth, lifted end end plate, hat type or expansion, etc., making it possible to eliminate the need for flat plate ribs in the conventional planar configuration, eliminating the need for rib material, and welding the rib part It is possible to eliminate the need for work and the need to paint the ribs, making it possible to manufacture low-pressure chambers that are extremely inexpensive and not seen in the past.

The housing of the low-pressure chamber is a flat mirror plate, dish-shaped mirror plate, regular semi-elliptical mirror plate, approximate semi-elliptical mirror plate, deep dish-shaped mirror plate, missing ball, special dish-shaped mirror plate, hemispherical mirror plate, pipe cap, cone-shaped mirror plate, An eccentric conical, a bell mouth, a lifted end panel, a hat type, an expansion, or the like can be used.

FIG. 1 is an elevation view of a low-pressure chamber using the present invention, FIG. 2 is a plan view, and FIG. 3 is a side view. In the example, the casing is made of a regular semi-ellipsoidal end plate made of Hockai Co., Ltd. and made of a general structural rolled steel SS400.

First, the structure of the low pressure chamber will be described. The low-pressure chamber 1 is arranged so that the housing 2 to which the housing flange 3 is airtightly welded and the housing 4 to which the housing flange 5 is airtightly welded face each other, and one or both of the housing flanges 3 and 5 are arranged. A packing 6 is disposed on the outer periphery of the.

Next, a method for opening and closing the low pressure chamber will be described. The casing 2 of the low-pressure chamber 1 is tightly connected to the legs 13, and the legs 13 are tightly connected to the gantry 14 and installed on the floor. One housing 4 is fastened to linear guide bearings 11 and 12 that can linearly move on linear guide rails 9 and 10 fastened to fixing brackets 7 and 8 fastened to the other housing 2, respectively. Therefore, in order to open and close the low pressure chamber 1, the housing 4 may be linearly moved on the linear guide rails 9 and 10.

Next, the habitability of the low pressure chamber will be described. In the low pressure chamber 1, a floor 21 is installed, and chairs 22 and 23 are also installed. Therefore, the resident can sit on the chairs 22 and 23 and relax.

Next, elimination of the feeling of anxiety in the low pressure chamber will be described. In such a sealed space, some occupants feel stuffy and feel uncomfortable, but a flange 16 is hermetically welded to the casing opening 15 of the casing 2, and an O-ring 17 and a transparent acrylic plate are connected to the flange 16. 18 and the flange 20 are fastened with a bolt 19 to maintain airtightness.

Next, the materials of the casings 2 and 4 constituting the low pressure chamber will be described. In the embodiment, the material of the casings 2 and 4 is the general structural rolled steel SS400 that can be recycled in consideration of the global environment, but is not necessarily limited thereto. The materials of the housings 2 and 4 may be other metal materials, and may be plastics material, wood, or other materials. A combination of these materials may also be used. Moreover, a transparent material or an opaque material may be sufficient.

Next, the method for opening and closing the low-pressure chamber is not necessarily limited to linear motion. An opening / closing mechanism based on rotational motion may be used, and an opening / closing mechanism based on a combination of linear motion and rotational motion may be used.

The special dish-shaped end plate means those of the MD, XD, and UD symbols, which are in-house standards of Hockai Co., Ltd. In addition, as for the names of the other end plates, the names of Hockai Co., Ltd. were all cited.

Conventionally, when trying to install a low-pressure chamber in one corner of an apartment, condominium, or other small house, a rectangular parallelepiped low-pressure chamber has a casing structure with a plane configuration called a hexahedron. In order to ensure the pressure resistance of the flat surface, a rib structure in which ribs are arranged vertically and horizontally on one side or both sides of the flat plate has to be used. Therefore, preparation of rib material, rib welding work, and rib painting work are required, and the rectangular parallelepiped low-pressure chamber has a limit in reducing production cost, but this invention makes it extremely easy for anyone, anytime, anywhere. It has become possible to obtain a low-pressure chamber at low cost, and thus it has become extremely easy to experience a high-altitude pressure environment.

In terms of industrial applicability, it is expected to be widely used not only for general households, but also for schools, gyms, hotels, hot springs, golf rest houses, hospitals, osteopaths, nursing homes, professional athletes, low-pressure room service shops, etc. The
