A bulging surface-facing wall 43 that is in contact with the inner wall and a substantially triangular sealing hollow portion 44 on the inside, with the fitting base 41 as a vertex toward the frame side of the sliding door 3 and having a substantially triangular cross section. One-piece molding using synthetic resin with excellent durability and fitting of semi-rigid resin Certain parts 41 as having been formed by co-molding.

  The large sliding door device A has, for example, a height of about 2.8 m and a width of, for example, a large opening between columns and a ceiling and a floor of an RC structure building, for example, at an appropriate position between the fitting part 1 and the floor. The large-sized sliding door 3 having a large area terrace type so as to be about 4 m is appropriately disposed, and the sliding door 3 is fitted and the indoor side of the portion 1 is used as a door bag and is superposed and accommodated therein. The window opening frame 2 defined by the upper frame 21, the lower frame 22, the left and right vertical frames or the vertical 23 arranged on the interior side of the window frame integrally or separately from the window frame 2 is opened or closed in a single-drawing or drawing manner. In this case, the building has a deck flush with the floor on the outside of the room, and the sliding door 3 can be opened and closed to enter and exit the deck.

  The large sliding door 3 has an expected width increased by arranging, for example, three glass panels in a double insulation space. For example, the upper and lower sides having an expected width of about 8 to 9 cm are set to about 4 m above and below, and 2. It is made of aluminum in which an eaves frame is formed by assembling upper eaves 31, lower eaves 32, and left and right vertical eaves 33 made of thick aluminum extruded material of about 8 m, and is attached to the upper frame 21 of the window opening frame 2. By guiding the upper rod 31 to the formed groove rail and the lower rail door wheel 321 to the projecting rail formed on the lower frame 22, the horizontal pulling opening / closing of the above-mentioned single pull or draw between the left and right vertical frames or the vertical 23 is performed. To do.

  The upper rod 31, the lower rod 32, and the left and right vertical rods 33 that form the rod frame are respectively used on the indoor side surface of the rod or separated from each other so that the outer peripheral end portion in the out-of-plane direction is located on the same plane on the indoor side. A series of wide and airtight material contact surfaces are provided by fixing the airtight material receiving material afterward, and the sealed airtight material 4 of the window opening frame 2 is in contact with the airtight material contact surface. This ensures high airtightness when the sliding door 3 is closed at the outer peripheral end in the out-of-plane direction.

  The sealing airtight material 4 is fitted into an airtight material receiving groove 24 formed in the upper frame 21, the lower frame 22, the left and right vertical frames or the vertical 23 of the window opening frame 2 according to a conventional method. The window opening frame 2 is projected so as to be in contact with the frame frame, and at this time, the airtight material receiving groove 24 is located on the same surface at the outer peripheral end of the window opening frame 2 in the out-of-plane direction. By recessing the outdoor side surface integrally with the indoor side like the upper frame 21 and the vertical frame 23 and projecting a pair of protrusions integrally like the lower frame 22 or fixing a separate receiving groove member by retrofitting Similarly, they are arranged in series.

  The sealing and airtight material 4 can use rubber, synthetic resin, etc., but in this example, it is made of synthetic resin excellent in elasticity and durability as it repeats contraction by air suction and elastic bulge by air supply. In this example, a fitting base 41 made of a semi-rigid resin with fins is simultaneously molded on the silicon rubber to ensure the elasticity and durability. At the same time, the fitting base 41 can be securely fitted into the airtight material receiving groove 24 and prevented from coming off.

In this example, the hermetic sealing material 4 has both sides projecting so as to expand from the fitting base 41 fitted into the hermetic material receiving groove 24 of the window opening frame toward the frame of the sliding door 3 as described above. A pair of widening inclined walls 42, and a bulging surface contact wall 43 that bulges toward the frame side of the sliding door 3 that connects the protruding direction ends of the widening inclined wall 42 and that faces the wall frame; The fitting base 41 is used as an apex and is formed in a substantially triangular cross section toward the frame side of the sliding door 3. That is, the hermetic sealing material 4 of the present example has a pair of widened inclined walls 42 having a thickness of, for example, 2 to 3 mm and a projecting width of the sliding door to the frame side of about 1.5 cm. A bulging width is provided with a bulging surface contacting wall 43 at the front end in the projecting direction having a surface width of about 2.5 to 3 cm between the expanding inclined walls 42, and a substantially triangular sealing hollow portion 44 is also provided inside. It is as a thing.

  The hermetic sealing material 4 is also arranged in series with respect to the series of hermetic material receiving grooves 24 of the window opening frame 2, and the series of arrangements include, for example, the upper frame 21 and the lower frame of the window opening frame 2. 22 and a long airtight material cut into the length of a vertical frame or a vertical wall 23 are cut at 45 ° angles at both ends in the longitudinal direction, and the cut ends are abutted, for example, welding or bonding As a rectangular frame having the same shape as the rectangular airtight material receiving groove 24 of the window opening frame 2, the fitting base 41 is fitted into the airtight material receiving groove 24. As a result, the sealing hermetic material 4 is formed in a rectangular shape including the corner portion so as to form a sealed hollow portion 44 that communicates in series with each other, and contraction of air suction by the vacuum suction device and expansion by air supply are performed. You can get out.

The suction pipe 5 is, for example, a metal or hard resin pipe having a circular cross section, and the tip of the suction pipe 5 is inserted into the inside of the sealed hollow portion 44 of the sealed airtight material 4 from a through hole formed in the fitting base 41 of the sealed airtight material 4. The suction pipe 5 is connected to the hermetic airtight material 4 and the suction pipe 5 of this example is formed by cutting the front end of the hermetic airtight material 4 into a rectangular shape facing the outer peripheral direction. The opposing opening 51 of the suction pipe 5 is formed with a specific opening 51 and is inserted into the hermetic seal material 4 so as to be arranged in the longitudinal direction of the hermetic seal material 5.

  That is, in this example, the suction pipe 5 is inserted so as to pass through the fitting base 41 of the hermetic seal member 4 so that the fitting base 41 is elastically inserted and sealed as necessary. By taking measures, the insertion is performed with high airtightness, and the suction pipe 5 is prevented from oscillating or coming off to prevent airtightness from being lost.

  In this example, the vacuum suction device 7 is formed with an air supply electromagnetic valve 71, an air suction electromagnetic valve 72 and a vacuum pump 74 that are operated by the operation switch 6, and an air supply electromagnetic valve. An air filter 73 is disposed on the valve 71. At this time, the vacuum suction device 7 includes an air supply solenoid valve 71, an air suction solenoid valve 72, and a vacuum pump 74 in the longitudinal direction of the suction pipe 5 connected to the hermetic seal material 4, and an air supply solenoid valve 71. A series of air suction and supply systems are formed by connecting an air filter 73 to the air filter 73. At this time, in this example, the electromagnetic valves 71 and 72, the vacuum pump 74 and the like are accommodated in a box 78 which is collectively accommodated in the box 78, except that the connection side of the suction pipe 5 to the hermetic seal 4 is projected to the outside. For example, an operation switch for operating the vacuum suction device 7 is configured such that the above-described contraction and bulging of the hermetic sealing material 4 can be controlled by installing it at a predetermined position under the floor. 6 includes, for example, an open button 61 having a display corresponding to the opening and closing of the sliding door 3, a switch button of the close button 62, and a display lamp 63 in an open / closed state corresponding thereto. It is embedded or attached at the first operation position.

At this time, the vacuum suction device 7 of this example is further operated by air suction by the operation switch 6 and includes a timer 75 for starting air supply after a set time has elapsed, and also detects air pressure by detecting the internal pressure of the suction pipe 5. a pressure switch 76 to initiate, there as having in addition to the operating switch 6, these timers 75 in the present embodiment, the pressure switch 76 also housed in the same manner as described above box 78, the vacuum suction unit It is intended to make

  That is, the vacuum suction device 7 is in a state where the solenoid valves 71 and 72 for air supply and air suction are opened as shown in FIG. When the open button 61 of the operation switch 6 is pressed to open / close the air supply, the air supply electromagnetic valve 71 located on the side of the sealing airtight member 4 of the suction pipe 5 remains open as shown in FIG. The air suction electromagnetic valve 72 is closed and the vacuum pump 74 is operated, and the air suction supply system is used as an air suction system to form an air flow in the direction of the arrow. By vacuum-sucking the air from the sealed hollow portion 44, the sealed airtight material 4 is contracted elastically to separate it from the frame of the sliding door 3, thereby freeing the frame of the sliding door 3. The sliding door 3 is opened and closed.

  When the close button 62 of the operation switch 6 is pressed, as shown in FIG. 9, the air supply electromagnetic valve 71 is closed and the air suction electromagnetic valve 72 is opened, the vacuum pump 74 is stopped, and the air suction is performed. Using the air supply system as an air supply system, an air flow in the direction of the arrow is formed in the sealed hollow portion 44 of the sealed airtight material 4 in a reduced pressure state via the suction pipe 5, and an air supply electromagnetic wave is supplied from the air filter 73. Air is supplied through the valve 71 to elastically bulge the hermetic seal 4 and closely adhere to the frame of the sliding door 3, so that the window opening frame 2 and the frame of the sliding door 3 are spaced from each other. The airtightness of the sliding door 3 is secured to prevent the sliding door 3 from being opened and closed by the frictional resistance of opening and closing due to the close contact, and the closed state of the sliding door 3 is maintained.

  In this example, the timer 75 is operated by pressing the open button 61 and closes the air supply solenoid valve 71 after a preset time, for example, 2 to 3 hours has elapsed. , Using the air suction supply system as an air supply system, air is supplied from the air filter 73 via the air supply solenoid valve 71, and the sealing hermetic material 4 is elastically expanded without operating the close button 62. The sliding door 3 is brought into close contact with the frame and the closed state of the sliding door 3 is maintained.

  On the other hand, the pressure switch 76 is disposed in the suction pipe 5 between the hermetic seal material 4 and the air supply electromagnetic valve 71, and the pressure switch 76 determines the internal pressure of the sealing hollow portion 44 in the suction pipe 5, that is, the hermetic seal material 4 in advance. When the set lower limit value is reached, this is detected, and the air suction by the vacuum pump 74 is started using the air suction supply system as the air suction system in the same manner as when the open button 61 is pressed.

  That is, when the sealed airtight member 4 is vacuumed by operating the open button 61 and contracted, the vacuum pump 74 is stopped, while the timer 75 is activated to extend the state in which the sliding door 3 can be opened and closed by the contraction. If maintained over time, as time passes, for example, as shown in FIG. 8, the air suction system causes a very small amount of air leakage in the direction of the arrow, and air is supplied to the hermetic seal 4. As a result, the shrinkage of the sealing hermetic material 4 is gradually damaged and this bulges out. In some cases, the sealing hermetic material 4 comes into contact with the frame of the sliding door 3, and the sliding door 3 is maintained in an openable / closable state. There remains a possibility that the opening and closing will be impossible. However, the state in which the pressure switch 76 reaches the lower limit value of the internal pressure, that is, the sealed airtight material 4 contracted by vacuum suction is slightly swollen or formed in the frame of the sliding door 3. contact When the internal pressure that hinders the openable / closable state is detected, the internal pressure is detected, and the vacuum pump 74 of the vacuum suction device 7 in the air suction system is operated, so that the sealed airtight material 4 is renewed at that time. In this way, the sliding door 3 is maintained in an openable / closable state.

  In the figure, 64 is a lead wire of the operation switch, 77 is a control plate of the vacuum suction device 7, 8 is a blind or screen door, 81 is its guide rail, and 82 is its winding shaft.

  In the large sliding door device A of the present example configured as described above, by operating the vacuum suction device 7 by the operation switch 6, the air is sucked from the sealed hollow portion 44 of the sealed hermetic material 4, and the sealed hermetic material 4 The sealing hermetic material 4 is separated from the frame of the sliding door 3 toward the indoor side by contracting, and after the sliding door 3 is closed, air is supplied to the sealing hollow portion 44 to conversely. 4 is elastically bulged to the outside of the door so as to be in close contact with the frame of the sliding door 3, thereby eliminating the frictional resistance of the hermetic sealing material 4 against the frame of the sliding door 3, Both reliable opening and closing and ensuring high airtightness in the closed state of the sliding door 3 can be realized at the same time.

At this time, the sealing hermetic material 4 of the present example has a substantially triangular cross section, and the bulging surface contact wall 43 is in contact with the frame, so that a very high airtightness is secured when the sliding door 3 is closed. The bulging surface contact wall 43 is received between the pair of expanding inclined walls 42 on both sides by air suction, and the sealing airtight material is contracted by narrowing and closing the space between the pair of expanding inclined walls 42 on both sides. For this purpose, the hermetic sealing material 4 can be smoothly and reliably separated from the frame of the upper rod 31, the lower rod 32 and the vertical rod 33, and is swelled in reverse by the air supply so It can be in close contact. The suction pipe 5 is provided with a partial opening 51 at its distal end, by which is disposed toward the opening 51 in the longitudinal direction of the sealing gas-tight material 4, when the suction by operating the vacuum pump 74, the suction pipe 5 The suction port strongly adsorbs the bulging surface contact wall 43 so that the suction port is not blocked, thereby causing the contraction failure of the sealing airtight material 4 and the shrinkage by the air suction and the air supply at all times. Swelling can be performed reliably.

  Furthermore, the vacuum suction device 7 can be made as reliable as possible with a simple structure as much as possible, and can have a long-term durability of air suction and air supply to the sealed airtight material 4 and a timer 75 is provided. By installing the sliding door 3, the sliding door 3 can be opened and closed without operating the operation switch 6 during a set time that is expected to be opened and closed. By arranging the switch 76, the possibility of slight air leakage remains, preventing the openable state of the sliding door 3 from being obstructed, and the sealed airtight material 4 is always kept during the timer setting time. The state where the sliding door 3 can be opened and closed can be reliably maintained as the contracted state.

  Although the illustrated example is as described above, a window opening is included in the implementation of the present invention, including that the sealing hermetic material has an appropriate shape such as a rectangular shape and a circular shape capable of contraction and expansion. Frame, its airtight material receiving groove, sliding door, its frame, sealed airtight material, suction pipe, vacuum suction device, operation switch, if necessary, opposed opening of suction pipe, solenoid valve for air suction, solenoid for air supply Each specific structure, shape, material, relationship thereof, addition to these, etc., such as a valve, a vacuum pump, a timer, a pressure switch, etc. can be in various forms as long as it does not contradict the gist of the present invention.
