Description

The present invention relates to a door panel gap shielding device that shields a gap between a door panel and a floor surface to prevent sound leakage and light leakage. The gap shielding device according to the present invention can be applied to door panels of hinged doors and sliding doors, and partition panels (door panels) of partitioning devices.

This type of gap shielding device is disclosed in, for example, Patent Document 1 (name of invention: sealing device for door bottom). The sealing device of Patent Document 1 includes a retractable element protruding from the side surface of the door on the hanging side when opened, a slide piece that slides in response to the retracting motion of the retractable element, and a curved piece that slides according to the sliding movement of the piece. It is equipped with a pair of deformable leaf springs and a seal frame supported by both leaf springs. A sound absorbing material is housed inside the seal frame that opens downward, and a pair of seal lips are provided above and below the seal frame. When the door is closed, the infestation moves in and out of the door, the distance between the slide pieces is reduced by that amount, the leaf spring is curved like a downward protrusion, and the seal frame is pressed against the floor to press the door and floor. Shield the gap between the faces.

In the gap shielding device of the present invention, the floor contact body that shields the gap is supported by the parallel link mechanism, but the supporting structure of the shielding body using the parallel link is described in Patent Document 2 (Title of the invention: door device for moving partition). ). In the door device of Patent Document 2, a concave groove that opens downward is provided in the lower part of the door body, an elevating member is housed inside the groove, and a push rod provided at the hanging source of the door and a slide operation are performed by the rod. The parallel link mechanism is operated by the shaft to raise and lower the elevating member. The elevating member is pushed up and urged by a return spring. When the door is closed and the push rod is pushed into the door, the link swings downward and pushes the elevating member against the floor surface to block the gap between the door and the floor surface.

In the sealing device of Patent Document 1, a pair of seal lips come into contact with the floor surface to provide sound insulation and shading. However, since the infestation child is pushed into the door to lower the seal frame, the seal frame starts contacting the floor before the door reaches the closed position, and the seal is dragged by the door. The frame is pressed against the floor. Therefore, the seal frame between the floor contact start position and the floor contact completion position moves with the door while being in contact with the floor surface with frictional resistance, and the door is opened and closed lightly in the vicinity of the closed position. Can not. In addition, the seal lip is worn or habituated as the door is opened and closed, and the sound insulation effect and the light shielding effect are likely to be impaired at an early stage, which has the disadvantage of shortening the replacement interval of the seal frame.

In that respect, in the door device of Patent Document 2, the groove width of the concave groove is made larger than the thickness of the elevating member and a gap is provided between the two, so that the elevating member and the door are relatively moved in the vicinity of the floor contact completion position. Therefore, it is possible to prevent the elevating member from being dragged by the door. However, the door device of Patent Document 2 has a structure in which the parallel link is swung downward by the action of pushing the push rod into the inside of the door, and the elevating member is pressed against the floor surface. Therefore, as in the sealing device of Patent Document 1, the elevating member is pressed against the floor surface in a state of being dragged by the door, and the door cannot be opened and closed lightly in the vicinity of the closed position. In addition, the elevating member at the floor contact completion position must be tilted by the amount of relative movement between the elevating member and the door, and there is a risk that a part of the seal portion provided at the lower end of the elevating member will be separated from the floor surface and cannot be brought into close contact with the floor. There is.

As described above, in the conventional device, the door cannot be opened and closed lightly due to the friction between the floor contact body and the floor surface in the vicinity of the closed position, but there are cases where the door is more difficult to open and close. For example, in the case of a private room in a high-rise hotel, the pressure difference between the inside and outside of the door may be large due to the high airtightness of the building. It was necessary to win and open the door, and it was desired to develop a gap shielding device that could open and close the door lightly.

An object of the present invention is to slowly move the floor contact body downward from the time when the floor contact body starts descending until it touches the floor surface, and the floor contact body touches the floor while being dragged by the door panel. Therefore, it is an object of the present invention to provide a gap shielding device for a door panel, which can easily close and operate the door panel, prevent wear of the seal body of the floor contact body, and improve durability.

A floor contact spring 24 for urging is provided. The trigger mechanism 11 is configured to be switchable between a standby position for restricting the downward movement of the floor contact body 9 and a release position for allowing the downward movement of the floor contact body 9. In the state where the trigger mechanism 11 is switched from the standby position to the release position, the elevating mechanism 23 can start descending from the upward posture. After the trigger mechanism 11 in the standby position starts to be switched to the release position side, the delay structure is activated while the floor contact body 9 moves downward toward the floor contact position, and the floor contact timing of the floor contact body 9 is activated. It is characterized by delaying.

The elevating mechanism 23 is provided with a delay structure. The delay structure is composed of a damper 25 that brakes the downward movement of the elevating mechanism 23. While the trigger mechanism 11 is switched from the standby position to the release position and the elevating mechanism 23 moves downward from the upward posture, the descent movement of the elevating mechanism 23 is braked by the damper 25 to adjust the contact timing of the floor contact body 9. I'm delaying. The delay structure composed of the damper 25 may be used alone or in combination with the delay structure described above for delaying the descent start timing of the elevating mechanism 23.

The link release mechanism 11B includes a closing detector 78 that detects that the door panel 2 has been closed. The link release mechanism 11B is configured to be switchable between a first state of holding the link holding mechanism 11A in the standby position and a second state of switching the link holding mechanism 11A to the release position according to the operation of the closing detector 78. NS. When the door panel 2 is in the open position, the link release mechanism 11B is in the first state. When the closing detector 78 detects that the door panel 2 has been closed, the link releasing mechanism 11B switches to the second state and switches the link holding mechanism 11A to the releasing position (see FIG. 1). The delay structure operates in conjunction with the link release mechanism 11B starting the switching operation from the first state to the second state, delaying the timing at which the link holding mechanism 11A switches to the second state, and raising and lowering the mechanism.

When the door panel 2 is in the open posture, the link holding mechanism 11A is held in the standby position by engaging the trigger claw 63 with the engaging pin 62 of the first slide frame 61. When the detector 78 detects that the door panel 2 has been closed, the second slide frame 77 runs idle with respect to the first slide frame 61, and then the activation arm 84 of the second slide frame 77 triggers a claw. The trigger claw 63 and the engaging pin 62 are disengaged by swinging the 63, and the link holding mechanism 11A is switched to the disengaging position.

The first slide frame 61 and the second slide frame 77 are connected so as to be relatively slidable via a pin 85 and an elongated hole 83 (see FIG. 3). The second slide frame 77 is vacant with respect to the first slide frame 61 from the time when the closing detector 78 starts moving in and out until the starting arm 84 of the second slide frame 77 touches the trigger claw 63. It is designed to run. At the end of the retracting stroke of the closing detector 78, the starting arm 84 of the second slide frame 77 swings the trigger claw 63 to release the engagement between the trigger claw 63 and the engaging pin 62.

It has a body 97.

In the gap shielding device for the door panel according to the present invention, the delay structure operates while the floor contact body 9 moves downward toward the floor contact position after the trigger mechanism 11 starts switching to the release position side. The contact timing of the contact body 9 was delayed. According to the gap shielding device provided with the delay structure as described above, the floor contact body 9 comes into contact with the floor before the door panel 2 is completely closed, and the floor contact body 9 is worn due to sliding on the floor surface F. This can contribute to improving the durability of the door panel 2 provided with the gap shielding device. Since it is possible to prevent the floor contact body 9 from sliding on the floor surface F and generating a frictional force, the door panel 2 can be lightly closed and operated.

According to the delay structure including the second actuating body 77 and the first actuating body 61 which are relatively slidably connected via the pin 85 and the slot 83, when the trigger mechanism 11 is switched from the standby position to the release position. , The second actuating body 77 can idle with respect to the first actuating body 61 to delay the descent start timing of the elevating mechanism 23. By delaying the lowering start timing of the elevating mechanism 23 in this way, the floor contact body 9 can be brought into contact with the floor surface F after the door panel 2 is completely closed, so that the floor contact body 9 can come into contact with the floor surface F. The durability can be improved by surely preventing the wear by sliding on the top. Further, while the trigger mechanism 11 is switched from the standby position to the release position, the second actuating body 77 is allowed to run idle with respect to the first actuating body 61, and then the elevating mechanism 23 starts descending in a delayed state. Therefore, the elevating motion amount of the elevating mechanism 23 can be set independently of the switching operation amount of the trigger mechanism 11. Therefore, if the lifting operation amount of the lifting mechanism 23 is set to be large according to the facing gap between the floor contact body 9 and the floor surface F, even if the facing gap changes to a large or small size, the difference in the facing gap can be seen. In the absorbed state, the floor contact body 9 can be reliably brought into contact with the floor surface F, and it is not necessary to adjust the elevating movement amount of the elevating mechanism 23 according to the difference in the facing gap. You can save the trouble of.

According to the delay structure composed of the damper 25 that brakes the descending movement of the elevating mechanism 23, the moving speed of the elevating mechanism 23 that moves downward can be reduced by the damper 25. The time required for the floor body 9 to come into contact with the floor surface F can be extended to delay the floor contact operation of the floor contact body 9. By slowly lowering the floor contact body 9 in this way, the door panel 2 can be closed completely while the floor contact body 9 starts descending and then comes into contact with the floor surface F. Therefore, the floor contact body 9 can be closed. Can be reliably prevented from sliding on the floor surface F and being worn, and its durability can be improved.

The elevating mechanism 23 is composed of a pair of sliders 26 and 27, an upper link 28, a pair of inclined links 29, and a parallel link mechanism provided with a lower link 30, and the movement of the mechanism is controlled by the elevating roller 41 and the guide groove 56. It is now possible to regulate only up and down movement. According to such an elevating structure 10, the elevating roller 41 and the guide groove 56 regulate the lower ends of the pair of inclined links 29 to move up and down in an arc, or the lower link 30 to move left and right, in parallel. The link mechanism can be moved up and down vertically between the contact position and the leave position. Therefore, in the state where the parallel link mechanism 23 is switched to the downward posture, the floor contact body 9 is properly and evenly pressed against the floor surface F to shield the gap between the door panel 2 and the floor surface F from end to end. Therefore, the sound insulation effect and the light shielding effect can be effectively exerted. Further, the floor contact body 9 can be provided from one end to the other end of the door panel 2.

The trigger mechanism 11 and the holder body 50 are arranged with the elevating mechanism 23 sandwiched between them, and the floor contact spring 24 and the damper 25 are arranged between the holder body 50 fixed to the guide frame 8 and the elevating mechanism 23. .. According to such an elevating structure 10, with one end of the floor contact spring 24 and the damper 25 fixedly supported by the holder body 50, the other end of the floor contact spring 24 and the damper 25 is connected to the elevating mechanism 23 to connect the floor contact spring 24 and the damper 25 to the floor contact spring. The urging force of 24 and the braking force of the damper 25 can be appropriately applied to the elevating mechanism 23. Therefore, the elevating mechanism 23 can be smoothly moved between the lower posture and the upper posture in a stable state at all times. Further, since the floor contact spring 24 and the damper 25 and the holder body 50 supporting both of them can be centrally arranged on one side of the elevating mechanism 23, the elevating structure 10 can be avoided from becoming complicated and the labor of assembly can be saved. Can be omitted.

A strip-shaped floor contact frame 15 and a seal body 16 mounted on the floor contact frame 15 constitute a floor contact body 9, and the floor contact frame 15 and the seal body 16 are mounted grooves 17 provided on the floor contact frame 15. And the mounting rib 21 provided on the seal body 16 are engaged and integrated. According to such a floor contact body 9, the mounting groove 17 and the mounting rib 21 can be engaged with each other by inserting and mounting the floor contact frame 15 from one end to the other end of the seal body 16, so that the floor contact body 9 requires less effort. Can be assembled. Further, since the connecting groove 47 of the hanging piece 43 is engaged and connected by using the groove wall 17a projecting from the inner surface of the floor contact frame 15, the hanging piece 43 is connected to the floor contact frame 15. It is not necessary to separately provide the structure of the above, and the cost required for manufacturing the gap shielding device can be reduced as a whole.

The trigger mechanism 11 is composed of a link holding mechanism 11A, a link releasing mechanism 11B, and a delay structure provided between both mechanisms 11A and 11B, and the link holding mechanism 11A can be switched between a standby position and a releasing position. Further, the link release mechanism 11B is configured to be switchable between the first state and the second state according to the operation of the closing detector 78. According to such a trigger mechanism 11, the delay structure operates in conjunction with the link release mechanism 11B starting the switching operation from the first state to the second state, and the link holding mechanism 11A is switched to the second state. The timing of the change can be delayed. Further, in the state where the link release mechanism 11B is switched to the second state, the link holding mechanism 11A can be switched to the release position to allow the parallel link mechanism 23 to descend. Therefore, the timing at which the link holding mechanism 11A is switched to the release position can be adjusted by the delay structure, and unlike the conventional device that lowers the parallel link mechanism 23 in conjunction with the closing operation of the door panel 2, the parallel link mechanism 23 is lowered. By delaying the start timing, it is possible to reliably prevent the floor contact body 9 from being dragged by the door panel 2.

The trigger base 60, the first slide frame 61, the engaging pin 62, and the trigger claw 63 constitute the link holding mechanism 11A, and the link releasing mechanism 11B includes the second slide frame 77, the closing detector 78, and the return spring. 79 was provided. In such a trigger mechanism 11, in a state where the door panel 2 is closed, the second slide frame 77 runs idle with respect to the first slide frame 61 as the closing detector 78 moves back and forth. The starting arm 84 of the second slide frame 77 swings the trigger claw 63 to disengage the trigger claw 63 and the engaging pin 62, and the link holding mechanism 11A can be switched to the disengaging position. Further, when the door panel 2 is open, the second slide frame 77 and the closing detector 78 can be slid and moved by the urging force of the return spring 79 to quickly raise the parallel link mechanism 23 to the upward posture. .. As described above, according to the trigger mechanism 11 configured as a mechanical mechanism, the link holding mechanism 11A and the link releasing mechanism 11B can be switched only by the opening / closing operation of the door panel 2 and the urging force of the return spring 79, so that the link holding mechanism 11A and the link releasing mechanism 11B can always be switched. The parallel link mechanism 23 can be accurately moved up and down in a stable state. Further, as compared with the case where an actuator such as a motor or a solenoid is used as a drive source, there is an advantage that the structure of the gap shielding device can be simplified and the gap can be shielded without any problem even in the event of a power failure.

A trigger in which the first slide frame 61 and the second slide frame 77 are connected so as to be relatively slidable via a pin 85 and an elongated hole 83 so that the second slide frame 77 runs idle with respect to the first slide frame 61. According to the mechanism 11, the engagement between the trigger claw 63 and the engaging pin 62 can be disengaged at the end of the retracting stroke of the closing detector 78. Therefore, the lowering start timing of the parallel link mechanism 23 can be sufficiently delayed, and the contact of the floor contact body 9 with the floor surface F before the door panel 2 is completely closed can be more reliably eliminated.

According to the manual trigger mechanism 11 composed of the connecting body 95, the manual switching mechanism 96, the transmission body 97, and the like, compared with the case where the trigger mechanism 11 is automatically switched in conjunction with the closing operation of the door panel 2. , The structure of the trigger mechanism 11 can be remarkably simplified to provide a gap shielding device at a lower cost. Further, since the descending movement of the elevating mechanism 23 can be started only by switching the operating tool 106 of the manual switching mechanism 96, the floor contact body 9 is dragged to the door panel 2 as long as the proper usage is followed. Can be resolved.

In the manual trigger mechanism 11, the moderation mechanism for holding the position of the operating tool 106 in the first state and the second state is composed of a moderation recess 107, a moderation protrusion 108, and a moderation spring 109. According to such a trigger mechanism 11, the moderator recess 107 and the moderation protrusion 108 are engaged with each other in conjunction with the operation of switching the operation tool 106 between the first state and the second state, so that the operation tool 106 is in the first state and It is possible to prevent the switching operation from being inadvertently performed in the second state. Further, the moderation mechanism can prevent the parallel link mechanism 23 held in the upward posture from trying to move downward due to an external force or an impact.

The manual switching mechanism 96 is composed of an operation tool 106 and a slide body 118, and the operation tool 106 is composed of an operation knob 119 and an operation lever 120 that moves the slide body 118 up and down in conjunction with the operation knob 119. According to such a manual switching type trigger mechanism 11, the structure of the trigger mechanism 11 is remarkably simplified as compared with the automatic switching type trigger structure in which the trigger mechanism 11 is automatically switched in conjunction with the closing operation of the door panel 2. , The gap shielding device can be provided at a lower cost. Further, since the downward movement of the parallel link mechanism 23 can be started only by switching the operating tool 106 of the manual switching mechanism 96, the floor contact body 9 is dragged to the door panel 2 as long as the proper usage is followed. Can be surely resolved. Further, since the connecting body 95 can be switched between the standby position and the release position by swinging the operation knob 119, the operation knob 119 can be easily switched as compared with the case where the operation tool 106 is slid up and down. Can be done. Since the moderation mechanism is composed of a kick spring 133 made of a twisting coil spring, the structure of the moderation mechanism can be simplified and contributes to cost reduction.

According to the trigger mechanism 11 provided with the opening restricting structure for restricting the switching operation of the manual switching mechanism 96, the movable regulating portion 114 and the fixed regulating portion 115 are engaged with each other when the door panel 2 is opened. Therefore, it is possible to regulate that the operating tool 106 is switched to the second state. Further, since the operating tool 106 can be switched to the second state only when the movable restricting portion 114 and the fixed restricting portion 115 are disengaged, the floor contact body 9 is formed before the door panel 2 is completely closed. Can be more reliably eliminated from being dragged by the door panel 2 in contact with the floor surface F.

According to the gap shielding device provided with the automatic switching type trigger structure and the manual switching type trigger structure, the operation knob 119 of the manual switching type trigger mechanism 11 is switched to the first state when the door panel 2 is open. By doing so, the floor contact body 9 can be held at the leaving position even when the door panel 2 is closed. Further, by closing the door panel 2 and then switching the operation knob 119 to the second state, the floor contact body 9 can be slowly brought into contact with the floor surface F. Further, when the door panel 2 is opened while the operation knob 119 is switched to the second state, the trigger mechanism 11 of the automatic switching method is activated to move the floor contact body 9 up to the bed leaving position. be able to. As described above, in the state where the operation knob 119 of the manual switching type trigger mechanism 11 is switched to the first state, the switching operation of the automatic switching type trigger mechanism 11 linked to the opening / closing operation of the door panel 2 is invalidated. NS. Therefore, depending on the purpose of the room opened and closed by the door panel 2, the state of the gap shielding device is switched between the case where it is necessary to prevent sound leakage and the case where it is not necessary, and the floor contact body 9 Can be eliminated from being unnecessarily contacted with the floor surface F.

It is fixed with two screws 51. A hook pin 54 for the floor contact spring 24 and a cylinder hole (connecting hole) 55 for the damper 25 are formed on the left end surface of the holder body 52. Further, a vertically long guide groove 56 for guiding the elevating roller 41 is formed on the rear surface of the holder main body 52. In this way, by guiding the elevating roller 41 with the vertically long guide groove 56, when the parallel link mechanism 23 moves up and down, the parallel link mechanism 23 is restricted from swinging left and right, and the floor contact body 9 is placed in a horizontal posture. As it is, it can be properly adhered to the floor surface F.

In FIG. 3, the trigger mechanism 11 is a delay structure provided between the link holding mechanism 11A, the link releasing mechanism 11B, and both mechanisms 11A and 11B, and is configured as an automatic switching type trigger structure. The link holding mechanism 11A can switch between a standby position in which the lower link 30 of the parallel link mechanism 23 is held in a standby position so as not to be lowered and a release position in which the lower link 30 is allowed to be lowered. As shown in FIG. 5, the link holding mechanism 11A has a trigger base 60 that is engaged and mounted on the guide groove 13, and a first slide frame (first operating body) that is connected to the upper link 28 and slides along with the link 28.

It consists of pressed metal fittings. An engaging step portion 73 that engages with and disengages from the engaging pin 62 is formed on the lower surface of the intermediate portion of the engaging arm 71. The trigger claw 63 is pivotally supported on the claw receiving wall 66 of the trigger base 60 by a pin 74 so that the engaging arm 71 and the passive arm 72 are at the engaging positions shown in FIG. 3 and FIG. It can be tilted up and down between the release positions shown in. The engaging step portion 73 at the engaging position engages with the engaging pin 62 to restrict the slider 26 from moving to the right. Further, the engaging step portion 73 at the disengaging position is separated from the engaging pin 62 to allow the slider 26 to move to the right.

The link release mechanism 11B detects that the second slide frame (second operating body) 77 slidably supported by the guide frame 8 and the door panel 2 attached to the second slide frame 77 have been closed. A closing detector 78 and a return spring 79 arranged between the second slide frame 77 and the trigger base 60 are provided. The second slide frame 77 is a plastic integrally provided with a frame body 80 that is slidably guided by a guide groove 13 of the guide frame 8 and a vertically horizontally long vertical wall 81 projecting from the lower surface of the frame body 80. It consists of a molded product. The frame main body 80 is formed with an accommodating recess 82 for the closing detector 78 that opens upward, and the vertical wall 81 is formed with a horizontally long slide hole (long hole) 83. Further, a lateral activation arm 84 that swings the trigger claw 63 via the passive arm 72 is projected from the lower right end of the vertical wall 81. The second slide frame 77 and the first slide frame 61 are connected so as to be relatively slidable by guiding a guide pin (pin) 85 that is caulked and fixed to the first slide frame 61 with a slide hole 83.

The closing detector 78 is housed in a housing recess 82 together with a bolt 88 having a hexagonal operating head, a flat latch body 89 screwed and connected to the bolt 88, and a bolt 88, and retracts the bolt 88. It is composed of a compression coil type spring 90 that is urged. The bolt 88 is fixed by a cover 91 that closes the upper surface of the accommodating recess 82 (see FIG. 8). The return spring 79 is composed of a compression coil type spring, and the sliders 26 and 27 are moved to the left to return the floor contact body 9 from the floor contact position to the bed leaving position, and at the same time, the closing detector 78 is advanced to the outside of the guide frame 8. do. Therefore, the tension of the return spring 79 is set to be larger than the tension of the floor contact spring 24. As shown in FIG. 10, the latch body 89 is guided by the guide groove 13 of the guide frame 8 so as to be retractable, and an arcuate pressure receiving surface 92 is formed at the tip of the latch body 89.

The link release mechanism 11B can be switched between a first state of holding the link holding mechanism 11A in the standby position and a second state of switching the link holding mechanism 11A to the release position according to the movement of the closing detector 78 to appear and disappear. Is. The link release mechanism 11B in the state where the door panel 2 is open is switched to the first state as shown in FIG. 3, and the second slide frame 77 receives the urging force of the return spring 79 from the trigger base 60. Extruded in the direction away from each other, the latch body 89 of the closing detection body 78 protrudes from the side end surface of the door panel 2. Further, the link release mechanism 11B in the state where the door panel 2 is closed switches from the first state to the second state and switches the link holding mechanism 11A to the release position, the details of which will be described later. The delay structure is composed of a second slide frame 77 and a first slide frame 61 that are relatively slidably connected via a pin 85 and a slide hole 83.

The gap shielding device configured as described above can be assembled, for example, as follows. With the elevating roller 41 engaged with the guide groove 56, the damper holder 50 and the elevating structure 10 are temporarily assembled, and the floor contact spring 24 and the damper 25 are assembled between them. The holder body 52 of the damper holder 50, the sliders 26 and 27 of the elevating structure 10, and the trigger base 60 are fitted into the guide groove 13, and the link release mechanism 11B including the return spring 79 is housed in the guide frame 8 to form a gap. Temporarily assemble the main members of the shielding device. Next, the trigger base 60 is fixed to the guide frame 8 with the screw 59, the damper holder 50 is fixed to the guide frame 8 with the screw 51, and the relationship position between the trigger base 60, the parallel link mechanism 23, and the damper holder 50 is fixed. do. In this state, the floor contact frame 15 is inserted and engaged with the hanging piece 43 protruding outside the guide frame 8, and the floor contact body 9 is integrated with the parallel link mechanism 23.

The floor contact body 9 is configured by engaging the mounting groove 17 provided in the floor contact frame 15 with the mounting rib 21 provided in the seal body 16. In that case, the floor contact frame 15 is one end of the seal body 16. Since the mounting groove 17 and the mounting rib 21 can be engaged with each other by inserting and mounting from the other end to the other end, the floor contact body 9 can be assembled with less effort. Further, since the connecting groove 47 of the hanging piece 43 is engaged and connected by using the groove wall 17a projecting from the inner surface of the floor contact frame 15, the hanging piece 43 is connected to the floor contact frame 15. It is not necessary to separately provide the structure of the above, and the cost required for manufacturing the gap shielding device can be reduced as a whole.

The gap shielding device in the above state is fitted into the mounting groove 2a of the door panel 2 and fixed with screws, and the door panel 2 is supported by the hinge 3 so as to be swingable and openable. The door panel 2 suspended from the opening frame 1 is closed and rocked to confirm the timing at which the floor contact body 9 starts to contact the floor surface F, and the amount of protrusion of the close detection body 78 from the guide frame 8 is adjusted. do. For example, when the floor contact timing is too early, the latch body 89 is pulled out of the guide frame 8 against the urging force of the spring 90, the latch body 89 is screwed into the bolt 88, and the guide frame of the closing detector 78 is screwed. The amount of protrusion from 8 is reduced. If the contact timing is too late, the latch body 89 is loosened with respect to the bolt 88 to increase the amount of protrusion. The gap shielding device can be commonly used even when the hanging source of the door panel 2 is on the right side of the opening frame 1. In that case, as shown by an imaginary line in FIG. 10, the latch body 89 It is preferable to reverse the direction of the pressure receiving surface 92 so that the direction is reversed.

The gap shielding device when the door panel 2 is closed operates as follows. When the door panel 2 is open, the trigger claw 63 engages with the engaging pin 62 to hold the parallel link mechanism 23 in the upward position as shown in FIG. 3, and the elevating roller 41 has a guide groove. It is located at the upper end of 56. Further, the closing detection body 78 receives the urging force of the return spring 79, the tip of the latch body 89 projects outward from the guide frame 8, and the floor contact spring 24 is in an extended state. That is, the link holding mechanism 11A holds the parallel link mechanism 23 on standby so that it cannot descend, and the link releasing mechanism 11B switches to the first state and holds the link holding mechanism 11A in the standby position. The seal body 16 in this state is housed in the guide frame 8 as shown in FIG.

As the door panel 2 is closed from the above state, the side surface of the door panel 2 on the hanging side approaches the opening frame 1, and eventually the tip of the latch body 89 is received by the opening frame 1 and returns. It is pushed into the guide frame 8 while resisting the spring force of the spring 79. When the closing detector 78 is pushed in and moves to the right, the second slide frame 77 moves with it, but the moving operation of the frame 77 is absorbed by the slide hole 83, and the second slide frame 77 is the first slide frame 61. The first slide frame 61 does not move because it runs idle. When the second slide frame 77 is subsequently moved to the right, the starting arm 84 abuts on the passive arm 72 of the trigger claw 63 as shown in FIG. 9, and the trigger claw 63 is swung in the counterclockwise rotation direction. Then, when the trigger claw 63 swings to the position indicated by the imaginary line, the engagement between the engaging step portion 73 and the engaging pin 62 is released, and the restraint of the first slide frame 61 by the trigger claw 63 is released.

Further, when the second slide frame 77 is idled with respect to the first slide frame 61, the engagement between the trigger claw 63 and the engaging pin 62 can be released at the end of the retracting stroke of the closing detector 78. .. Therefore, the lowering start timing of the parallel link mechanism 23 can be sufficiently delayed, and the contact of the floor contact body 9 with the floor surface F can be reliably eliminated before the door panel 2 is completely closed. After that, the sliders 26 and 27 and the upper link 28 receive the spring force of the floor contact spring 24 and start moving to the right. As described above, the link release mechanism 11B switches from the first state to the second state and switches the link holding mechanism 11A to the release position immediately before the door panel 2 is completely closed.

When the slider 27 starts to move to the right, the braking force of the damper 25 acts on the slider 27, so that the parallel link mechanism 23 and the floor contact body 9 slowly descend and come into contact with the floor surface F. As shown, the seal portion 20 is pressed against the floor surface F. At this time, since the speed at which the door panel 2 swings to the closed position is sufficiently faster than the speed at which the floor contact body 9 descends, the floor contact body 9 is placed on the floor surface F with the door panel 2 completely closed. You can touch the floor. When the floor contact body 9 is in the floor contact position, the elevating roller 41 is located near the lower end of the guide groove 56 as shown in FIG. As described above, when the elevating roller 41 is guided so as to be movable up and down by the guide groove 56 of the damper holder 50, the lower link 30 tries to move left and right with the damper holder 50 fixed to the guide frame 8 as a position reference. Can be regulated by the elevating roller 41 and the guide groove 56. Therefore, the parallel link mechanism 23 can be moved up and down more accurately.

As described above, the activation arm 84 abuts on the passive arm 72 of the trigger claw 63, and the trigger claw 63 starts swinging in the counterclockwise rotation direction just before the door panel 2 is completely closed. The slide stroke S of the starting arm 84 (second slide frame 77) from the start of the claw 63 to the disengagement of the engaging step portion 73 and the engaging pin 62 is shown in FIG. There are only a few. Further, from the time when the sliders 26 and 27 slide to the right and the seal body 16 starts descending from the floor leaving position to the floor contacting position and is pressed against the floor surface F, it takes several seconds for the braking operation of the damper 25. During that time, the door panel 2 moves to a completely closed position and stops. Therefore, the floor contact body 9 is pressed against the floor surface F after the door panel 2 is completely closed.

As described above, in the gap shielding device of the first embodiment, the second slide frame 77 is idled with respect to the first slide frame 61 to delay the descent start timing of the elevating mechanism 23, and further, the elevating mechanism moves downward. The moving speed of the 23 is reduced by the damper 25, the time required for the floor contact body 9 to come into contact with the floor surface F after the floor contact body 9 starts descending is extended, and the floor contact operation of the floor contact body 9 is performed. Was delayed. According to such a gap shielding device, the floor contact body 9 can be brought into contact with the floor surface after the door panel 2 is completely closed, and the floor contact body 9 slides on the floor surface F and is worn out. It can be reliably prevented and its durability can be improved. Since the floor contact body 9 is prevented from sliding on the floor surface F to generate a frictional force, there is also an advantage that the door panel can be easily closed and operated.

Further, by allowing the second slide frame 77 to run idle with respect to the first slide frame 61, the lowering start timing of the elevating mechanism 23 can be delayed. Further, while the trigger mechanism 11 is switched from the standby position to the release position, the second slide frame 77 is idled with respect to the first slide frame 61, and then the elevating mechanism 23 starts descending in a delayed state. Therefore, the elevating motion amount of the elevating mechanism 23 can be set independently of the switching operation amount of the trigger mechanism 11. Therefore, if the lifting operation amount of the lifting mechanism 23 is set to be large according to the facing gap between the floor contact body 9 and the floor surface F, even if the facing gap changes to a large or small size, the difference in the facing gap can be seen. In the absorbed state, the floor contact body 9 can be reliably brought into contact with the floor surface F, and it is not necessary to adjust the elevating movement amount of the elevating mechanism 23 according to the difference in the facing gap. You can save the trouble of.

When the door panel 2 is opened from the closed position, the closing detector 78 that receives the urging force of the return spring 79 moves to the guide frame 8 as the side end surface of the door panel 2 begins to separate from the opening frame 1. The second slide frame 77 moves to the left at the same time. Further, since the first slide frame 61 moves along with the second slide frame 77 moving to the left, the parallel link mechanism 23 starts to rise from the lower posture to the upper posture. At this time, the piston rod 25d of the damper 25 is pushed out by the advance urging spring 25c and follows the second slide frame 77 without resistance, so that the parallel link mechanism 23 rapidly rises and moves due to the urging force of the return spring 79. Then, the engaging step portion 73 of the trigger claw 63 engages with the engaging pin 62 to hold the parallel link mechanism 23 in the upward position. Incidentally, the ascending speed of the parallel link mechanism 23 when the door panel 2 is opened from the closed position is sufficiently faster than the ascending speed when the parallel link mechanism 23 descends while being braked by the damper 25. The link release mechanism 11B while the engaging step portion 73 of the trigger claw 63 engages with the engaging pin 62 switches from the second state to the first state, and the latch body 89 projects outward from the guide frame 8. do. The trigger claw 63 swings downward due to a moment in the clockwise rotation direction due to its own weight and engages with the engaging pin 62. If necessary, the trigger claw 63 may be downwardly urged by a dedicated spring.

As described above, the elevating mechanism according to the above embodiment includes a pair of sliders 26 and 27, an upper link 28, a pair of inclined links 29, and a parallel link mechanism 23 including a lower link 30. According to such a parallel link mechanism 23, since the pair of sliders 26 and 27 are connected by the upper link 28 and the pair of inclined links 29 are connected by the lower link 30, the pair of sliders 26 and 27 are accurately synchronized. While sliding in the state, the pair of inclined links 29 can be moved up and down in a state of being accurately synchronized. Further, the upper end of the pair of inclined links 29 slides along with the pair of sliders 26 and 27, while the lower end of the pair of inclined links 29 accompanies the lower link 30 and moves up and down. Therefore, the inclined link 29 does not move up and down so that the lower end thereof draws an arc, and can be moved up and down vertically between the lower posture and the upper posture. Further, since the parallel link mechanism 23 can vertically move the floor contact body 9 up and down, the floor contact body 9 can be provided from one end to the other end of the door panel 2. Therefore, in the state where the parallel link mechanism 23 is switched to the downward posture, the floor contact body 9 is properly and evenly pressed against the floor surface F to shield the gap between the door panel 2 and the floor surface F from end to end. Therefore, the sound insulation effect and the light shielding effect can be effectively exerted.

Further, in the above embodiment, the trigger mechanism 11 and the damper holder 50 are arranged with the parallel link mechanism 23 sandwiched between them, and the floor contact spring is placed between the damper holder 50 fixed to the guide frame 8 and the parallel link mechanism 23. 24 and the damper 25 are arranged. According to such an elevating structure 10, with one end of the floor contact spring 24 and the damper 25 fixedly supported by the damper holder 50, the other end of the floor contact spring 24 and the damper 25 is connected to the parallel link mechanism 23 to contact the floor. The urging force of the spring 24 and the braking force of the damper 25 can be appropriately applied to the parallel link mechanism 23. Therefore, the parallel link mechanism 23 can be smoothly moved between the floor contact position and the floor leaving position in a stable state at all times. Further, since the floor contact spring 24 and the damper 25 and the damper holder 50 supporting both of them can be centrally arranged on one side of the parallel link mechanism 23, it is troublesome to assemble the elevating structure 10 without becoming complicated. Can be omitted.

According to the trigger mechanism 11 composed of the link holding mechanism 11A and the link releasing mechanism 11B, when the closing detector 78 detects that the door panel 2 has been closed, the link releasing mechanism 11B switches to the second state. Therefore, the link holding mechanism 11A can be switched to the release position to allow the parallel link mechanism 23 to descend. Therefore, the timing at which the link holding mechanism 11A is switched to the release position can be adjusted on the side of the link release mechanism 11B, and unlike the conventional device that lowers the parallel link mechanism in conjunction with the closing operation of the door panel, the parallel link mechanism 23 It is possible to delay the start of descent of the floor contact body 9 and prevent the floor contact body 9 from being dragged by the door panel 2.

The trigger mechanism 11 is configured as a mechanical mechanism, and the link holding mechanism 11A and the link releasing mechanism 11B can be switched only by the opening / closing operation of the door panel 2 and the urging force of the return spring 79. Therefore, the parallel link mechanism 23 can be appropriately moved up and down in a stable state at all times, and the structure of the gap shielding device is simplified and the cost is reduced as compared with the case where an actuator such as a motor or a solenoid is used as a drive source. In addition, there is an advantage that the gap can be shielded without any problem even in the event of a power failure.

(Example 2) FIGS. 12 to 14 show a gap shielding device for a door panel 2 according to a second embodiment of the present invention, wherein the trigger mechanism 11 is configured by a manual switching type trigger structure, and the first embodiment. It is different from the gap shielding device of the first embodiment in that the elevating structure 10 of the above is arranged in a state of being inverted left and right. In FIGS. 12 and 13, the trigger mechanism 11 performs a switching operation between the connecting body 95 fixed to the swing tip side of the floor contact body 9, the manual switching mechanism 96 provided on the door panel 2, and the manual switching mechanism 96. It is composed of a metal transmission rod (transmission body) 97 or the like that is transmitted to the connecting body 95.

The connecting body 95 is made of a plastic molded product integrally provided with a lower connecting portion 98 that is engaged and connected to the groove wall 17a of the floor contact frame 15 and a hanging frame portion 99 that projects upward of the floor contact frame 15. Become. A vertically long guide groove 100 that opens before and after the connecting body 95 is formed in the hanging frame portion 99, and a nut body 101 is slidably arranged vertically inside the groove 100. In the connecting body 95, a rod hole 102 that allows the transmission rod 97 to slide up and down is formed in a vertically penetrating shape. The upper end of the transmission rod 97 is connected to a slide knob 106, which will be described later, and the screw shaft 103 provided at the lower end thereof is screwed and connected to the nut body 101.

In FIG. 14, the manual switching mechanism 96 includes a case 105 mounted on the door panel 2 adjacent to the door handle 4, a slide knob (operation tool) 106 that is slidably guided up and down by the case 105, and a case 105. It is provided with a moderation mechanism provided between the slide knobs 106. The moderation mechanism includes a moderation recess 107 formed by being recessed at the top and bottom of the case 105, a moderation protrusion 108 that moves along with the slide knob 106, and a moderation spring 109 that pushes out and urges the moderation protrusion 108. The slide knob 106 is slid between the upper first state and the lower second state, and the position is held by the moderation mechanism at each switching position. When the slide knob 106 is switched to the first state, the connecting body 95 is held in the standby position and the floor contact body 9 can be held in the leaving position. Further, when the slide knob 106 is switched to the second state, the connecting body 95 can be switched to the release position and the descending movement of the floor contact body 9 can be started. Since the other parts are the same as those in the first embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted. The same shall apply in the following examples.

When the door panel 2 is open, as shown in FIG. 14, the slide knob 106 is switched to the upper first state, and the floor contact body 9 is held in the position of leaving the floor. When the slide knob 106 is pushed down to the second state to switch the connecting body 95 to the release position with the door panel 2 in this state completely closed, the parallel link mechanism 23 is started to move downward and the floor contact body. 9 can be brought into contact with the floor surface F while slowly moving downward. When opening the door panel 2 again, first, the slide knob 106 is switched to the upper first state to raise the transmission rod 97 and the nut body 101, and the upper surface of the nut body 101 contacts the upper end of the guide groove 100. In this state, the floor contact body 9 is moved upward with the accompaniment. As a result, the floor contact body 9 is suspended by the manual switching mechanism 96, and the parallel link mechanism 23 is switched to the upward posture against the urging force of the floor contact spring 24.

According to the manual switching type trigger mechanism 11 configured as described above, the structure of the trigger mechanism 11 is compared with the automatic switching type trigger structure in which the trigger mechanism 11 is automatically switched in conjunction with the closing operation of the door panel 2. Can be significantly simplified to provide a gap shielding device at a lower cost. Further, since the downward movement of the parallel link mechanism 23 can be started only by switching the operating tool 106 of the manual switching mechanism 96, the floor contact body 9 is dragged to the door panel 2 as long as the proper usage is followed. Can be surely resolved.

According to the trigger mechanism 11 in which the moderation mechanism is composed of the moderation recess 107, the moderation protrusion 108, and the moderation spring 109, the moderation recess 107 is interlocked with the operation of switching the operating tool 106 between the first state and the second state. And the moderation protrusion 108 can be engaged with each other to prevent the operating tool 106 from being inadvertently switched in the first state and the second state. Further, the moderation mechanism can prevent the parallel link mechanism 23 held in the upward posture from trying to move downward due to an external force or an impact.

(Example 3) FIGS. 15 to 17 show a gap shielding device for a door panel according to a third embodiment of the present invention, and the trigger mechanism 11 of the second embodiment is opened to regulate the switching operation of the manual switching mechanism 96. It differs from the gap shielding device of the second embodiment in that a regulating mechanism is added.

As shown in FIG. 16, the opening regulation mechanism includes a latch body (infestation body) 112 that appears and disappears at the side end of the door panel 2 on the swing tip side, a push spring (spring) 113 that pushes out and urges the latch body 112, and The latch body 112 is provided with an elongated hole-shaped regulation hole (movable regulation portion) 114 formed in a vertically penetrating shape, and a regulation groove (fixation regulation portion) 115 formed in the transmission rod 97 corresponding to the regulation hole 114. The front-rear width of the regulation hole 114 is set to be slightly larger than the diameter of the transmission rod 97.

In the state where the door panel 2 is open, as shown in FIG. 17, the latch body 112 is extruded and urged by the push spring 113, the latch body 112 protrudes from the side end of the door panel 2, and the regulation hole 114 is pushed. The end on the spring 113 side is engaged with the regulation groove 115. Therefore, the slide knob 106 cannot be pushed down from the first state to the second state. Further, when the door panel 2 is closed, the latch body 112 in contact with the opening frame 1 is pushed against the urging force of the push spring 113 as shown in FIG. 16, and the regulation hole 114 and the regulation groove are operated. Since the engagement of the 115 is released, the slide knob 106 can be pushed down to the second state to switch the coupling body 95 to the disengagement position, and the downward movement of the parallel link mechanism 23 can be started. The timing at which the regulation hole 114 and the regulation groove 115 are disengaged may be before the door panel 2 is completely closed, and even in that case, the floor contact body 9 can be slowly brought into contact with the floor surface F. , The floor contact body 9 can be eliminated from being dragged by the door panel 2. Further, it is possible to reliably regulate that the slide knob 106 is erroneously pushed down while opening and closing the door panel 2.

When opening the door panel 2 in the closed position, the slide knob 106 is pushed up from the second state to the first state to switch the parallel link mechanism 23 to the upward posture, and the floor contact body 9 is moved by the moderation mechanism. Hold the position at the bed leaving position. When the door panel 2 is opened in this state, the latch body 112 is extruded by the push spring 113 and protrudes from the side end of the door panel 2, the regulation hole 114 engages with the regulation groove 115, and the transmission rod 97 moves downward. To regulate. Therefore, it is possible to reliably prevent the floor contact body 9 from being dragged by the door panel 2 while being pressed against the floor surface F by switching the floor contact body 9 to the floor contact position when the door panel 2 is open.

(Example 4) FIGS. 18 and 19 show a gap shielding device for a door panel according to a fourth embodiment of the present invention, and the trigger mechanism 11 is configured with a trigger structure of a manual switching method different from that of the second embodiment. I made it. In FIG. 18, the manual switching mechanism 96 includes a case 105 mounted on the door panel 2 and an operating tool 106 that is supported by the case 105 so as to be swingable back and forth and can be switched between the first state and the second state. , A slide body 118 that is supported by the case 105 so as to be able to move up and down is provided. The operating tool 106 is arranged inside the thumb turn knob (operation knob) 119 arranged on the outer surface of the door panel 2 and the case 105, and moves the slide body 118 up and down in conjunction with the reciprocating swing of the thumb turn knob 119. A thumb turn lever (operation lever) 120 is provided, and both 119 and 120 are interlockably connected by an interlocking shaft 121 having a drum-shaped cross section. The elevating structure 10 in this embodiment is arranged in the same state as the elevating structure 10 in the first embodiment.

The slide body 118 includes a press fitting including a passive wall 123 that is long in the vertical direction and a connecting wall 124 that is connected and fixed to the upper end of the transmission rod 97. Above and below the edge of the passive wall 123 facing the thumb turn lever 120, there are a partial arc-shaped stopper portion 125 that is received by the tip of the thumb turn lever 120 and a U-shaped passive groove 126 that is raised and lowered by the thumb turn lever 120. It is formed. Further, slide pins 127 are fixed above and below the passive wall 123, and by guiding the pins 127 with vertically long guide grooves 128 provided in the case 105, the slide body 118 can be moved up and down in the case 105. It is supported.

The thumb turn lever 120 is formed by projecting a switching lever 130 and a spring receiving arm 131 on the opposite peripheral surface of the boss portion that engages with the interlocking shaft 121, and the stopper portion 125 at the tip of the switching lever 130 is formed. A locking surface 132 for receiving is formed. In order to hold the thumb turn knob 119 and the thumb turn lever 120 in the first state shown by the solid line and the second state shown by the imaginary line, a moderation mechanism composed of a kick spring 133 is provided between the case 105 and the thumb turn lever 120. ing. The kick spring 133 is formed of a torsion coil spring, forms a circular locking ring 134 at the ends of a pair of spring arms, and engages one of the locking rings 134 with a pin 135 fixed to the case 105. The other locking ring 134 is engaged with a pin 135 fixed to the spring receiving arm 131. When the thumb turn knob 119 and the thumb turn lever 120 are switched to the first state, the connecting body 95 is held in the standby position and the floor contact body 9 can be held in the leaving position. Further, the position is held by the moderation mechanism at each switching position. When the thumb turn knob 119 and the thumb turn lever 120 are switched to the second state, the connecting body 95 can be switched to the release position and the descending movement of the floor contact body 9 can be started.

When the door panel 2 is open, as shown in FIG. 18, the thumb turn knob 119 is switched to the first state, and the floor contact body 9 is held at the bed leaving position. With the door panel 2 in this state fully closed, when the thumb turn knob 119 is swung in the counterclockwise rotation direction to switch to the second state, the passive groove 126 of the slide body 118 is lowered by the switching lever 130. Then, the connecting body 95 is switched to the release position. Along with this, the parallel link mechanism 23 can be started to move downward, and the floor contact body 9 can be brought into contact with the floor surface F while slowly moving downward. When opening the door panel 2 again, first, the thumb turn knob 119 is swung in the clockwise direction to switch to the first state, the passive groove 126 of the slide body 118 is lifted by the switching lever 130, and the connecting body 95 is opened. To the standby position, as shown in FIG. 19, the transmission rod 97 and the nut body 101 are raised, and the floor contact body 9 is accompanied upward with the upper surface of the nut body 101 in contact with the upper end of the guide groove 100. Move. As a result, the floor contact body 9 is suspended by the manual switching mechanism 96, and the parallel link mechanism 23 is switched to the upward posture against the urging force of the floor contact spring 24.

According to the manual switching type trigger mechanism 11 configured as described above, the structure of the trigger mechanism 11 is compared with the automatic switching type trigger structure in which the trigger mechanism 11 is automatically switched in conjunction with the closing operation of the door panel 2. Can be significantly simplified to provide a gap shielding device at a lower cost. Further, since the downward movement of the parallel link mechanism 23 can be started only by switching the operating tool 106 of the manual switching mechanism 96, the floor contact body 9 is dragged to the door panel 2 as long as the proper usage is followed. Can be surely resolved. Further, since the connecting body 95 can be switched between the standby position and the release position by swinging the thumb turn knob 119, the thumb turn knob 119 can be easily switched as compared with the case where the operating tool 106 is slid up and down. Can be done. Further, since the moderation mechanism is composed of the kick spring 133, the structure of the moderation mechanism can be simplified and the cost can be reduced as compared with the moderation mechanism described in the second embodiment.

By switching, the floor contact body 9 can be held at the leaving position even when the door panel 2 is closed. Further, by closing the door panel 2 and then switching the thumb turn picking 119 to the second state, the floor contact body 9 can be slowly brought into contact with the floor surface F. Further, when the door panel 2 is opened while the thumb turn knob 119 is switched to the second state, the trigger mechanism 11 of the automatic switching method is activated to move the floor contact body 9 up to the bed leaving position. be able to. The ascending movement of the connecting body 95 at this time is absorbed by the relative sliding of the nut body 101 and the guide groove 100. As described above, in the state where the thumb turn knob 119 of the manual switching type trigger mechanism 11 is switched to the first state, the switching operation of the automatic switching type trigger mechanism 11 linked to the opening / closing operation of the door panel 2 is invalidated.
