  Hereinafter, examples of embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in FIG. 1, a high-pressure space forming apparatus 1 according to an embodiment of the present invention includes a high-pressure capsule 2, a high-pressure container door device 4, a compressor 6, and a base 8. The high-pressure capsule 2 includes a cylindrical body 20 made of a metal member such as aluminum or stainless steel, and hemispherical protrusions 22 and 22 that are installed at both ends of the body 20 and made of a transparent resin. , A relief mechanism 24 installed at one of the protrusions 22 and 22 and a plurality of communication for supplying high-pressure air, high-concentration oxygen, aromatic air for aroma, antenna wiring for TV, etc. to the internal space A tube 26 is provided. The high-pressure capsule 2 extends on the base 8 so that its longitudinal direction is horizontal, and a bed 28 is disposed inside. As a result, the user can sleep inside the high-pressure capsule 2.

  On the upper surface side of the high-pressure capsule 2, a rectangular opening 2A having an angular range of about 90 degrees in the circumferential direction and a size of about 1 meter in the longitudinal direction is formed. Specifically, the opening 2A is inclined so as to have an angle of about 40 degrees in the circumferential direction. Therefore, the user can smoothly enter and exit from the side of the high pressure capsule 2 through the opening 2A.

  The relief mechanism 24 is formed with handles 24A and 24A on both the inside and outside of the high-pressure capsule 2, and by using this handle 24A, the open valve portion 24B is slid to communicate the inside and outside space. . As a result, the high-pressure air inside the high-pressure capsule 2 is discharged to the outside through the release valve portion 24B, and can be quickly depressurized to the atmospheric pressure. If a user operates this relief mechanism 24 from the inside of the high-pressure capsule 2, the internal space can be depressurized to an atmospheric pressure environment and the door can be opened as will be described later. In addition, by operating the outer handle 24, an outsider can forcibly depressurize the internal space. Note that the compressor 6 compresses external air to generate compressed air. This compressed air is supplied to the inside of the high-pressure capsule 2 through the pressure control device 80 of the high-pressure container door device 4 and the communication pipe 26.

  Next, the high pressure container door device 4 will be described in detail.

  As shown in FIG. 2 in an enlarged manner, the high-pressure container door device 4 includes a door 40, a pair of reinforcing members 42, a pair of arm members 44, a tube 46, a tube receiving member 48, a gripping member 50, and a lower slide. A shaft 52, an upper slide shaft 54, a pair of lower slide shaft holding members 56, a pressure control device 80 (see FIG. 1), and the like are provided.

  The door 40 is a transparent resin plate member arranged inside the opening 2A. The door 40 is curved in a semi-cylindrical shape with substantially the same curvature as the body portion 20 of the high-pressure capsule 2, and has a size slightly larger than the opening 2A. Further, when the inside of the high-pressure capsule 2 is at atmospheric pressure, a gap S is formed between the door 40 and the opening 2A. When the door 40 is brought into close contact with the inner periphery of the opening 2 </ b> A so as to fill the gap S, the door 40 becomes a part of the high-pressure capsule 2 and a high-pressure environment is formed inside the high-pressure capsule 2. A gripping member 50 is installed on the door 40, and a user slides the door 40 with the gripping member 50.

  Arc-shaped reinforcing members 42 are installed at both ends in the longitudinal direction (axial direction) of the door 40 to increase the rigidity of the door 40. The lower slide shaft 52 is a rod-like member, and is fixed in the longitudinal direction to the inner wall of the body portion 20 of the high-pressure capsule 2 in the vicinity of the lower edge of the opening 2A. The upper slide 54 is also a rod-like member, and is fixed in the longitudinal direction to the inner wall of the barrel 20 of the high-pressure capsule 2 in the vicinity of the upper edge of the opening 2A. Therefore, the lower slide shaft 52 and the upper slide shaft 54 are parallel to each other so that both function as a horizontal guide mechanism, and the door 40 is slidably held in the horizontal direction by the guide mechanism.

  A lower slide shaft holding member 56 is fixed to the lower end of the reinforcing member 42, and the lower slide shaft 52 is inserted into the insertion hole 56 </ b> A of the lower slide shaft holding member 56. As a result, the lower slide shaft holding member 56 is slidable in the axial direction with respect to the lower slide shaft 52 and is swingable with the lower slide shaft 52 as a base point. Therefore, the lower slide shaft 52 functions as a swing shaft of the door 40 in addition to the horizontal guide mechanism.

  A door-side support shaft 42 </ b> A is installed at the upper end of the reinforcing member 42. In the vicinity of one end of the arm member 44, a long hole 44A into which the door side support shaft 42A is movably inserted in the arm longitudinal direction is formed, and in the vicinity of the other end, an insertion hole into which the upper slide shaft 54 is inserted. 44B is formed. A cylindrical slide tube 44C is fixed between the insertion holes 44B of the pair of arm members 44, and the upper slide shaft 54 is inserted into the slide tube 44C. Therefore, one end side of the arm member 44 is swingably connected to the door 40 via the door side support shaft 42A, and the other end side is swingably connected to the upper slide shaft 54 of the high-pressure capsule 2.

  The inside of the long hole 44 </ b> A and the door side support shaft 42 </ b> A become a sliding mechanism in the circumferential direction (longitudinal direction of the arm member 44), and vary the distance L between the door 40 and the high-pressure capsule 2 held by the arm member 44. Normally, the door-side support shaft 42A is positioned on the inner end 44AX side of the long hole 44A due to the dead weight of the door 40, the holding distance L is the shortest, and the gap S is the maximum. On the other hand, if the door side support shaft 42A is slid to the outer end 44AY side of the long hole 44A, the entire door 40 can be swung to the opening 2A side with the lower slide shaft 52 as a base point. As a result, the door 40 comes into close contact with the opening 2A.

  The tube receiving member 48 is a rod-like member, and both ends thereof are fixed by a pair of arm members 44 so as to be parallel to the slide tube 44C. The tube 46 is a band-shaped bag member into which compressed air can be introduced. When the compressed air is introduced into the tube 46, the entire tube swells into a rod shape. One side edge 46A of the strip-like tube 46 is fixed so as to be sandwiched between the tube receiving member 48 and the slide tube 44C. The other side edge 46B of the tube 46 is fixed to a fixing member 40B having an L-shaped cross section that is fixedly installed along the upper edge 40A of the door 40. The fixing member 40B also functions as a stopper by contacting the slide tube 44C.

  Therefore, as shown in FIG. 2, in a state where compressed air is not introduced into the tube 46, the tube 46 is crushed between the upper edge of the door 40 and the upper slide shaft 54 (slide tube 44C). . As shown in FIG. 3, when compressed air is introduced into the tube 46, the tube 46 expands between the tube receiving member 48 and the upper edge of the door 40, and the upper edge of the door 40 is pushed up. The door 40 is in close contact with the opening 2A.

  As shown in FIG. 4, two strip-shaped guide tubes 60 are arranged on each of the upper slide shaft 54 and the lower slide shaft 52 (not shown in FIG. 4). As shown in FIG. 5, the guide tube 60 is configured by connecting a plurality of bag portions 60A in a row, and a plurality of guide openings 60B are formed at locations where the bag portions 60A are avoided. ing. Since the guide openings 60B are formed at regular intervals in the longitudinal direction of the guide tube 60, the upper slide shafts 54 are formed in all the guide openings 60B by making the guide tubes 60 into ninety folds. Alternatively, the lower slide shaft 52 can be inserted. When compressed air is introduced into the bag portion 60A of the guide tube 60 folded ninety times, the bag portion 60A expands, so that the guide tube 60 extends in the axial direction.

  The guide tubes 60 are respectively disposed on both outer sides in the axial direction of the door 40 in each of the upper slide shaft 54 and the lower slide shaft 52. Accordingly, in each of the upper slide shaft 54 and the lower slide shaft 52, when compressed air is introduced into one guide tube 60 and the other guide tube 60 is opened to the atmosphere, the one guide tube 60 is released. Extends, the door 40 slides, and the door 40 closes. At this time, the guide tube 60 on the other side is in a ninety-nine fold state by being crushed by the door 40. Further, when compressed air is introduced into the other guide tube 60 and the one guide tube 60 is opened to the atmosphere, the other guide tube 60 extends and the door 40 slides. Opens. At this time, the guide tube 60 on one side is in a ninety-nine fold state by being crushed by the door 40. In this way, by installing the pair of guide tubes 60 on the upper slide shaft 54 or the lower slide shaft 52, the door 40 is automatically used by using the compressed air used to increase the internal pressure of the high-pressure capsule 2. It can be opened and closed.

  The pressure control device 80 includes a plurality of introduction valves, a solenoid that operates the valves, an electronic control mechanism such as a microcomputer, and the like. At the start of operation, the pressure control device 80 introduces compressed air into the tube 46 to increase its internal pressure, and also introduces compressed air into the high-pressure capsule 2 to increase the internal pressure. Furthermore, this pressure control device 80 controls the tube 46 to be opened to the atmosphere side to reduce the internal pressure after the internal pressure of the high pressure capsule 2 has increased to a certain level. Thereafter, the internal pressure of the high-pressure capsule 2 is further increased to the target value, and a use state is obtained. After use, the internal pressure of the high-pressure capsule 2 is gradually decreased and finally matched with the atmosphere. The pressure control device 80 also controls the introduction of compressed air to the four guide tubes 60 described above.

  Next, a procedure for using the high-pressure space forming apparatus 1 will be described.

  As shown in FIG. 6, at the start of use, the pressure control device 80 controls expansion and contraction of the guide tube 60 and slides the door 40 in the axial direction along the upper slide shaft 54 and the lower slide shaft 52. Let it open. The opening can also be performed manually using the gripping member 50. Thereafter, the user enters the high-pressure capsule 2 through the opening 2 </ b> A and sleeps on the bed 28. Thereafter, using the operation panel inside the high-pressure capsule 2, the expansion and contraction of the guide tube 60 is controlled again, and the door 40 is automatically closed. When the door 40 is closed as shown in FIG. 1, the tube 46 of the high-pressure container door device 4 is inflated by the control of the pressure control device 80, and the gap S between the door 40 and the opening 2 </ b> A is eliminated. Thereafter, when the compressed air is fed into the high-pressure capsule 2 by the pressure control device 80, the internal pressure increases. When the internal pressure of the high-pressure capsule 2 becomes high, the door 40 is pressed against the inner peripheral surface of the opening 2A by the internal pressure itself, so that the sealing performance is naturally increased, and the urging by the tube 46 becomes unnecessary. At that time, the pressure control device 80 opens the inside of the tube 46 to the atmosphere side. As a result, the compressed air inside the tube 46 is automatically discharged to the outside by the internal pressure of the high-pressure capsule 2, and the bag is completely crushed.

  As a result, the inside of the high-pressure capsule 2 becomes a high-pressure state. For example, high-concentration oxygen or the like is supplied to the inside to promote efficient absorption into the body and promote health.

  At the end, the internal pressure of the high-pressure capsule 2 is gradually decreased by the pressure control device 80. As already described, since the tube 46 is in a completely crushed state, a gap S is formed between the opening 2A and the door 40 by the dead weight of the door 40, and the high-pressure capsule 2 becomes atmospheric pressure. 40 becomes a slidable state. Therefore, the expansion and contraction of the guide tube 60 is controlled using the operation panel, and the door 40 is automatically opened. The user raises his / her body and exits from the opening 2 </ b> A to terminate the use of the apparatus 1.

  The high-pressure space forming apparatus 1 of the present embodiment fills the gap between the opening 2 </ b> A of the high-pressure capsule 2 and the door 40 by inflating the tube 46. Therefore, it becomes possible to operate the tube 46 by sharing the compressor 6 for increasing the internal pressure of the high-pressure capsule 2 and to efficiently create a sealed space. Further, the tube 46 is merely an opportunity to create a sealed space, and thereafter, the door 40 can be urged toward the opening 2A by the internal pressure of the high-pressure capsule 2 itself, so that the burden on the tube 46 can be reduced. As a result, it is no longer necessary to firmly fix the door for the doorway with a jig in order to withstand the internal pressure as in the prior art, and it is possible to achieve both convenience of access and comfort during use.

  Furthermore, in this embodiment, the tube 46 is arrange | positioned inside the door 40, and it has the structure which urges | biases the door 40 to 2A of opening by expansion of the tube 46. FIG. Therefore, since the tube 46 is not interposed between the opening 2A and the door 40, the sealed state of both can be stabilized. For example, by providing an elastic member such as silicon rubber or butyl rubber on the inner peripheral surface of the opening 2A, it is possible to further enhance the sealing performance of the door 40 and the opening 2A by this elastic member. Further, as shown in FIG. 4, the tube receiving member 48 and the tube 46 can be slid together with the door 40 on the inner wall side of the door 40, so that the tube 46 is prevented from coming into contact with the high pressure capsule 2 and being worn. it can. As a result, it is possible to reduce maintenance work and maintain a stable operation over a long period of time. Particularly, since the tube receiving member 48 is installed on the arm member 44 and the tube 46 is held by the tube receiving member 48, the tube 46 can be moved integrally with the door 40 with a simple configuration. .

  Moreover, in this embodiment, since the opening 2A and the door 40 are inclinedly arranged on the upper surface side of the trunk portion 20 of the high-pressure capsule 2, the user can easily enter and leave the high-pressure capsule 2. In order to increase the pressure resistance of the high-pressure capsule 2, it is difficult to make the opening 2A too large. For example, the upper limit of the circumferential angle range occupied by the opening 2A in the trunk portion 20 is considered to be about 120 degrees. Therefore, when the opening 2A is arranged right above the trunk portion 20, the user must go in and out so as to straddle the edge of the opening 2A. Therefore, as in the present embodiment, the opening 2A and the door 40 are arranged so as to be inclined in the circumferential direction with respect to the trunk portion 20, so that the lower edge of the opening 2A is arranged at a low position, so that it can be easily accessed. It is possible to do.

  Further, in the high pressure space forming apparatus 1, the lower and upper slide shafts 52 and 54, the pair of lower slide shaft holding members 56, and the pair of arm members 44 function as a horizontal guide mechanism for the door 40. The capsule 2 can be opened and closed easily by smoothly sliding in the axial direction.

  Moreover, since the guide tube 60 which expands and contracts with gas is installed in this horizontal direction guide mechanism, the door 40 can be opened and closed automatically. Moreover, since the power source of the guide tube 60 can share the compressor 6 for generating high pressure of the high-pressure capsule 2, the apparatus configuration can be simplified.

  In the present embodiment, the arm 40 is connected between the door 40 and the high pressure capsule 2 (upper slide shaft 54). In detail, since the arm member 44 uses the pivoting support shaft at the two points of the door-side support shaft 42A and the upper slide shaft 54, the door 40 can be smoothly swung with a high degree of freedom.

  In particular, in this embodiment, since the holding distance L between the door 40 and the high-pressure capsule 2 can be freely changed, it is possible to ensure a large gap S between the door 40 and the opening 2A. Opening and closing work can be made smooth. In particular, here, since the fulcrum of the door side support shaft 42A is slid by the long hole 44A formed in the arm member 44, the distance between the holdings can be changed with a simple configuration. In addition, the change in the distance between the holdings can be such that the arm member 44 itself can have an extendable structure in addition to sliding the fulcrum of the swing shaft through the long hole.

  Further, in the present embodiment, the lower slide shaft holding member 56 fixed to the door 40 holds the lower slide shaft 52. Accordingly, the lower slide shaft holding member 56 side makes the distance between the holding of the door 40 and the high-pressure capsule 2 unvariable, and therefore the entire door 40 swings with the lower slide shaft 52 as a base point. As a result, since the swinging motion of the door 40 is stabilized, it is possible to always stabilize the sealing performance between the door 40 and the opening 2A.

  In particular, in the present embodiment, the door 40 is inclined, and the lower slide shaft 52 is used as a rocking base point (fixed end) of the door 40 and is swung with the upper edge side of the door 40 as a moving end. Yes. As a result, when the door 40 is opened from the opening 2 </ b> A, the weight of the door 40 can be effectively utilized to swing the upper side of the door 40 so as to drop. Therefore, the door 40 can be more reliably separated from the opening 2A simply by lowering the internal pressure of the high-pressure capsule 2.

  In the above embodiment, although it showed only when the door 40 slides the inside of the high pressure capsule 2 to an axial direction (horizontal direction), this invention is not limited to it. For example, as shown in FIG. 7, a guide rail 90 is disposed in the circumferential direction, and the door 40 may slide in the circumferential direction along the guide rail 90. In this case, it is of course possible to arrange the guide tube 60 along the guide rail 90 and automatically open and close the door 40.

  Moreover, in this embodiment, although it showed only when moving the door 40 with the tube 46 and producing the clearance gap between the door 40 and opening 2A, this invention is not limited to it, The clearance gap between the door 40 and opening 2A. The tube 46 may be inserted and inflated on the side, and the tube 46 itself may serve to fill the gap S. In this case as well, by increasing the internal pressure of the high-pressure capsule 2 and reducing the internal pressure of the tube 46, the tube 46 is crushed and eventually the door 40 is directly urged to the opening 2A. it can.

  The high-pressure container door device and the high-pressure space forming device of the present invention are not limited to the above-described embodiments, and various changes can be made without departing from the scope of the present invention. .

  The present invention can be widely used in various fields for forming a high-pressure space.
