Abstract

[PROBLEMS] The present invention is capable of assembling both right-hand and left-hand doors in a low-pressure room installed not only in a decompression training facility for athletes but also in a corner of an apartment, condominium, or other small house. This is to provide a low pressure chamber.
The present invention relates to a low-pressure chamber main body composed of an end plate, a shell plate, and a door plate. The end plate is symmetrical, the shell plate is vertically symmetrical, and the door plate is vertically symmetrical. These parts are rearranged so that the door can be opened and closed freely for both the right hand and left hand.

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.

Conventionally, in Japanese Patent Publication No. 2-42992, an airtight room for exercise, in Japanese Patent Application Laid-Open No. 8-112373, a decompression training facility assuming pseudo high altitude training, and in Japanese Patent Application Laid-Open No. 11-336373, a decompression facility in which athletes can stay for a long time, Japanese Patent No. 2919111 And JP 2000-54666 propose large-scale decompression training facilities for exercise installed underground or semi-underground, but these all relate to the structure of a large-scale low-pressure chamber on the premise of movement. is there. Moreover, although a decompression training facility assuming pseudo high altitude training is proposed in Japanese Utility Model Application 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 is not only a decompression training facility for athletes, but also a low-pressure room installed in a corner of an apartment, condominium, or other small house. It is for providing.

The present invention is a low pressure chamber body composed of an end plate, a shell plate, and a door plate. The end plate is symmetrical, the shell plate is vertically symmetrical, and the door plate is vertically symmetrical. Then, by rearranging these parts and assembling them, an assembly-type low-pressure chamber that can be assembled with both the right-handed and left-handed doors is provided.

With the present invention, it is possible to provide a low-pressure chamber that can be assembled in either a right-handed or left-handed manner according to the layout of the building in a low-pressure room installed in a corner of an apartment, condominium, or other small house. Became.

The best mode for carrying out the present invention will be described. The assembleable low pressure chamber of the present invention is composed of the following three main components. That is, the end plate shown in FIG. 1, the shell plate shown in FIG. 2, and the door plate shown in FIG. The end plate 2 is symmetrical, and is reinforced to withstand external pressure by an end plate main rib 10 that runs in the lateral direction of the inner wall of the end plate and an end plate sub-rib 11 that runs in the vertical direction. The shell plate 3 is also vertically symmetrical and is reinforced to withstand external pressure by a shell plate main rib 17 that runs in the longitudinal direction of the inner wall of the shell plate and a shell plate sub-rib 18 that runs in the lateral direction. Further, the door plate 4 is also vertically symmetrical and is reinforced so as to be able to withstand external pressure by a door plate main rib 24 that runs in the lateral direction of the inner wall of the door plate and a door plate sub-rib 25 that runs in the vertical direction.

The method for assembling the low-pressure chamber that can be assembled according to the present invention will be described in detail. First, based on FIG. 4, the assembly method in the case of making door opening and closing right hand is demonstrated. In this case, the three components that are the main components are assembled from the left in the order of the end plate 2, shell plate 3, and door plate 4. The end plate 2 and the shell plate 3 are fastened by attaching bolts and nuts (not shown) to bolt holes 6 and 13 in which an end plate flange 5 and a shell plate flange 12 are provided in advance on the flange surface. In this case, sponge packing (not shown) is arranged on the outer periphery of the end plate flange 5 and the shell plate flange 12 in order to keep the low pressure chamber hermetic.

Next, a method for assembling the shell plate 3 and the door plate 4 will be described. The bearing unit 26 is tightly coupled to the right end of the shell plate 3 so as to rotatably support the door plate 4. Is inserted, and door arms 28 are fastened to the upper and lower ends of the shaft 27. A rotatable pin bracket 29 is inserted into the end of the door arm 28, and the pin bracket 29 is fastened to the upper and lower ends of the door plate 4. In this way, the low pressure chamber with the right door opening and closing is assembled.

The assembly method when the door opening / closing is left-handed will be described. In this case, the three components that are the main components are assembled from the right in the order of the end plate 2, the shell plate 3, and the door plate 4. Since the end plate 2 is symmetrical, there is no problem even if it is assembled in the opposite direction to the right-handed assembly described above. The end plate 2 and the shell plate 3 are fastened by attaching bolts and nuts (not shown) to bolt holes 6 and 13 in which an end plate flange 5 and a shell plate flange 12 are provided in advance on the flange surface. In this case, sponge packing (not shown) is arranged on the outer periphery of the end plate flange 5 and the shell plate flange 12 in order to keep the low pressure chamber hermetic.

Next, a method for assembling the shell plate 3 and the door plate 4 will be described. Since the door plate 4 is vertically symmetrical as described above, there is no problem even if it is assembled in an inverted state with respect to the right-handed assembly described above. A bearing unit 26 is fastened to the left end of the shell plate 3 to rotatably support the door plate 4 so that the door plate 4 can be freely opened and closed, and a shaft 27 is inserted into the bearing unit 26. A door arm 28 is fastened to the end. A rotatable pin bracket 29 is inserted into the end of the door arm 28, and the pin bracket 29 is fastened to the upper and lower ends of the door plate 4. In this way, the low-pressure chamber with a left-handed door opening and closing is assembled.

The present invention makes it possible to provide a low-pressure chamber that can be freely opened and closed according to the floor plan of the building, both right-handed and left-handed, and can only be installed in a corner of an apartment, condominium or other small house. In addition, when installing in low-pressure room service shops, etc., the degree of freedom of low-pressure room installation has greatly expanded.
