Description

  The present invention relates to a fire shutter device provided near a stairs in a building such as a large-scale store or building.

  In large-scale buildings such as department stores, supermarkets, shopping centers, and office buildings, in order to prevent the staircase from becoming a chimney in the event of a fire, block the opening of the passage connecting each floor and staircase. It is obliged to install a fire shutter device. Such a fire shutter device includes a so-called shutter portion that moves up and down to open and close the opening, and a fire door that is disposed adjacent to the shutter portion in order to ensure an evacuation path when a disaster occurs.

  Normally, a guide rail is provided on both sides of the shutter curtain in order to prevent the shutter curtain, which is an aggregate of a large number of slats suspended from above, from moving in and out, as described above. In the case of a simple fire shutter device, the guide rail on one side needs to guide the shutter on one side and receive the door end portion of the fire door on the other side. As shown in FIG. 20, this stand is arranged in the vicinity of the center of the passage from the floor to the ceiling so as to block the passage, so that it is disturbing for customers moving in the building during normal times. For this reason, it is necessary to consider the layout in the building so that the stand is as inconspicuous as possible.

Patent Document 1 discloses a fire door apparatus in which a guide rail of a shutter is provided at the door tip of the door so that such a stand is unnecessary. Patent Document 2 discloses an architectural shutter device having a structure in which a locking mechanism is provided at the front end of a fire door, and one side end of the shutter is locked and reinforced by this locking mechanism.

  However, in the structure of the fire door device disclosed in Patent Document 1, when a fire or the like occurs, it is necessary to first close the fire door to the closed position and then lower the shutter. Therefore, since the operation is in two stages, there is a problem that it takes time to close and is not necessarily preferable for safety.

  Further, according to the structure of the architectural shutter device disclosed in Patent Document 2, by providing a locking mechanism at the door end, the two-stage operation as in the structure disclosed in Patent Document 1 is not necessary. There is a problem that the structure of the locking mechanism is too complicated to be actually commercialized.

  Therefore, an object of the present invention is to provide a fire shutter device that can widely use a floor passage and has a simple structure, and can quickly complete a closing operation when necessary.

  The present invention will be described below. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

When the shutter is opened, the shutter is accommodated in the ceiling portion of the passage, and the door and the vertical portion are drawn to one of the walls on both sides of the passage. The vertical part is formed separately from the door, and is configured to be moved in the opening surface while maintaining an upright posture. The problem is solved by providing a fire shutter device, which is moved in the opening surface and can be unlocked and re-linked at a predetermined position of the vertical portion.

The invention of claim 2 is a fire shutter device (100) for closing a passage opening in a building, and at the time of closing, a shutter (300) arranged adjacent to the opening surface, a door (200), A vertical portion (400) disposed between the shutter and the door. When the shutter is opened, the shutter is accommodated in the ceiling portion of the passage, and the door and the vertical portion are drawn to one of the wall portions on both sides of the passage. The vertical part is formed separately from the door and is configured to be moved in the opening surface while maintaining an upright posture, and further, one end can be rotated to the upper part of the vertical part. An interlocking device attached to the lower end of the shutter so that the other end of the shutter can be pivoted, and with the interlocking device, the vertical portion is moved in the opening surface in conjunction with the raising and lowering of the shutter; Toribe part To provide a fire-proof shutter device characterized in that the interlocking device and the vertical part, or the interlocking device and the shutter can be disengaged and re-engaged by being disengaged at a position. The above-described problem is solved.

  According to the first aspect of the present invention, since the vertical portion is attracted to the side of the passage wall during normal times, it is on the passage and does not hinder traffic. Further, since the door and the vertical portion are separated, it is possible to easily adopt a structure capable of lowering the shutter while closing the door. Furthermore, since the vertical portion can be automatically moved in conjunction with the raising and lowering of the shutter, the shutter can be opened and closed while the vertical portion is automatically moved in the shutter direction.

  Hereinafter, the present invention will be described based on embodiments shown in the drawings.

  FIG. 1 is a perspective view showing the entirety of the fire shutter device 100. The illustrated fire shutter device 100 is a device that closes an opening plane A that is conceived when a passage in a building is cut by a plane perpendicular to the passage traveling direction, and is open during normal times. In the following description, for the sake of easy understanding, the case where the fire shutter device 100 is viewed from the lower left side in FIG. 1 is “indoor view”, and the case where the fire shutter device is viewed from the upper right side in FIG. Sight ". This is for ease of understanding, and the relationship between one and the other across the fire shutter 100 is not necessarily limited to the indoor / outdoor relationship.

  The plane A is surrounded by a four-sided frame consisting of an upper frame 10, a lower frame 20, a left vertical frame 30, and a right vertical frame 40. The fire prevention shutter device 100 includes a door 200, a shutter 300, and a vertical portion 400 disposed between the door 200 and the shutter 300 when closed.

  The door 200 is rotatably attached to the left vertical frame 30 by a hinge or the like. The door 200 includes a smaller inner door 210 inside thereof. The inner door 210 can be opened and closed even when the door 200 is closed. Even if there is a person locked out by the fire shutter device 100, the inner door 210 can be opened and closed. An evacuation route is secured.

  The vertical portion 400 is arranged adjacent to the left vertical frame 30 near the passage side wall W on the left side of the drawing in a normal state, and maintained an upright posture toward the center of the passage due to a fire alarm or the like. It is configured to stick out. The protrusion of the vertical portion 400 is supported by the interlocking device 500 described later, and the upper groove rail 11 and the lower groove rail 12 (upper portion of the upper frame) formed on the lower surface of the upper frame 10 and the upper surface of the lower frame 20. The groove rail 11 is not shown in FIG. 1 because it is in a blind spot.) The upper end portion 410 and the lower end portion 420 of the vertical portion 400 are moved in the direction toward the center of the passage along the vertical axis 400.

  When the shutter 300 is in a normal state, each slat 310 is wound up on a winder 330 in the shutter box by a motor 320 disposed in the ceiling of the passage. When the shutter 300 is lowered and closed due to a fire notification or the like, one end of the shutter 300 is guided and lowered by a guide groove (not shown) formed in the right vertical frame 40. On the other hand, the other end side of the shutter 300 is engaged with the guide rail 630 provided in the interlocking device 500 and the vertical part 400 by the guidance of the interlocking device 500. Thereby, the shake of the shutter 300 in the inner and outer directions is suppressed.

  Next, the moving mechanism of the vertical part 400 will be described with reference to FIGS. 2A is a perspective view showing the lower end portion 420 and the lower groove rail 12 of the vertical portion 400, and FIG. 2B is an enlarged perspective view of the lower end portion 420 and the lower groove rail 12 of the vertical portion 400. It is shown. FIG. 3 is a perspective view showing the contact ring mechanism 430 attached to the lower end portion 420 of the vertical portion 400. 4A is a front view, FIG. 4B is a side view of the contact ring mechanism shown in FIG. 3 (however, the lower groove rail 12 is also shown in this figure), c) is a plan view. Further, FIG. 5A is a view showing the entire vertical part 400 traveling between the upper groove rail 11 and the lower groove rail 12 in the outdoor view together with an interlocking device 500 described later, and FIG. 5B is a vertical part 400. It is a figure which expands and shows the lower end part 420 of FIG. FIG. 5 shows a case where the shutter device 100 is viewed from the upper right side of FIG.

  As is clear from FIGS. 2 and 5, a contact ring mechanism 430 is attached to the lower end portion 420 of the vertical portion 400. Although not shown, the contact ring mechanism 430 b is also attached to the upper end portion 410 of the vertical portion 400. The upper abutment ring mechanism 430b is guided by the upper groove rail 11 and the lower abutment ring mechanism 430 is guided by the lower groove rail 12. The upper abutment ring mechanism 430b and the lower abutment ring mechanism 430 have basically the same structure except that the upper and lower abutment ring mechanisms 430 are reversed to the upper side and the lower side. A description will be given on behalf of 430.

  As shown in FIGS. 3 and 4, in the contact ring mechanism 430, auxiliary plates 432 and 432 are attached to the front and back of the substrate 431 with screws 433, and one auxiliary plate 432 has two Horizontal wheels 434 and 435 are attached to the other auxiliary plate 432, and one vertical wheel 436 is rotatably attached thereto. A long hole 437 is formed in the substrate 431 in the vertical direction.

  4B, when the contact ring mechanism 430 is disposed in the lower groove rail 12, the horizontal wheels 434 and 435 are disposed on the side plate 12a of the lower groove rail, and the vertical ring 436 is disposed on the bottom plate 12c. Alternatively, it is brought into contact with the top plate 12d. Thus, the lower abutment ring mechanism 430 guides the lower end portion 420 of the vertical portion 400 so that it can smoothly travel along the lower groove rail 12 and restricts the vertical portion 400 from moving inward and outward.

  The upper contact ring mechanism 430b is fixed to the upper end portion 410 of the vertical portion 400 so as to freely rotate. On the other hand, the lower abutment ring mechanism 430 is attached to freely move in the vertical direction using a lower end portion 420 of the vertical portion 400 and a long hole 437 provided in the substrate 431. With this configuration, as shown in FIG. 5, the vertical portion 400 is given a certain degree of freedom of rotation between the upper groove rail 11 and the upper and lower groove rails 11 of the vertical portion 400 caused by the rotation. The expansion / contraction of the distance between 12 is adjusted between the lower groove rail 12 and the lower contact mechanism 430.

  Next, the interlocking device 500 that assists the horizontal operation of the vertical portion 400 will be described. FIG. 6 is a perspective view in an outdoor view in which members constituting the interlocking device 500 are taken out and shown. The interlocking device 500 includes an integrally formed connecting arm 510, a rotation support member 511, and a connecting portion 530. In addition to the integrally formed connecting arm 510, the rotation support member 511 and the connecting portion 530, a pair of receiving members 550 and 560 are provided. The rotation support member 511 is attached to the upper end portion of the connection arm 510, and the connection portion 530 is attached to the lower end portion of the connection arm 510.

  The structure of the interlocking device 500 will be described in more detail. 7A and 7B show the connecting arm 510, the rotation support member 511, and the connecting portion 530 that are integrally formed. FIG. 7A is a front view, FIG. 7B is a side view, and FIG. FIG. 7C shows a scale larger than those shown in FIGS. 7A and 7B for ease of viewing. The structure of the connecting arm 510, the rotation support member 511 and the connecting portion 530 that are integrally formed will be described with reference to FIG. As can be seen from FIG. 7C, the rotation support member 511 is a member having a substantially U-shaped horizontal cross section, and one side thereof is attached to the side surface of the connecting arm 510. Accordingly, as shown in FIGS. 7A and 7C, the rotation support member 511 is disposed so as to protrude from the side surface of the connection arm 510. Furthermore, holes 512 and 512 are provided in two sides of the rotation support member 511 that are not in contact with the connection arm 510. These two holes 512 and 512 have a center on the same axis in the vertical direction in the drawing in FIG.

  As shown in FIGS. 7A and 7B, the connecting arm 510 is a rod-shaped member. Further, as can be seen from FIG. 7C, the cross section is rectangular and has a hollow portion 513. Furthermore, one of the four sides which are rectangular has an opening 514 over the entire length, and the hollow portion 513 communicates with the outside. In addition, L-shaped members 510a and 510b are extended from both ends of the opening 514, and a connecting portion 530 described later is attached to one side of the L-shaped members 510a and 510b.

  The connecting portion 530 includes a pair of brackets 531a and 531b, a pair of first connecting rollers 532a and 532b, and a pair of second connecting rollers 533a and 533b. The brackets 531a and 531b are flat members, and have attachment portions 534a and 534b formed in an L shape only at portions where they are attached in contact with the L shape members 510a and 510b of the connecting arm 510. The bracket 531a is attached to the L-shaped member 510a of the connecting arm 510 via the attaching portion 534a, and the bracket 531b is attached to the L-shaped member 510b of the connecting arm 510 via the attaching portion 534b. Accordingly, the two brackets 531a and 531b are disposed substantially in parallel at a predetermined interval in portions other than the attachment portions 534a and 534b. Further, the direction is substantially perpendicular to the opening 514 of the connecting arm 510. Therefore, as can be seen from FIGS. 7B and 7C, a straight line is formed between the two brackets 531a and 531b from the outside (the left side in FIG. 7C and the front side in FIG. 7B). Can be inserted into the hollow portion 513 of the connecting arm 510. As will be described later, the opening 514 and the hollow portion 513 can be inserted into the end portion of the shutter 300 and have a role as a guide rail.

  A pair of first connection rollers 532a and 532b and a pair of second connection rollers 533a and 533b, which are attached to face each other, are disposed on the opposing surfaces of the two brackets 531a and 531b. The first connection roller 532a and the first connection roller 532b share an axis and are rotatable. The same applies to the second connecting roller 533a and the second connecting roller 533b. In addition, the distance between the first connection roller 532a and the first connection roller 532b facing each other and the distance between the second connection roller 533a and the second connection roller 533b are slightly wider than the distance between the openings 514 of the connection arm 510. Yes. Therefore, as described above, a straight line, that is, the end of the shutter 300 from the outside (the left side in FIG. 7C and the front side in FIG. 7B) between the two brackets 531a and 531b. The portion can be inserted into the hollow portion 513 of the connecting arm 510.

  Further, as can be seen from FIG. 7A, when the connection portion 530 is viewed from the front, the first connection rollers 532a and 532b and the second connection rollers 533a and 533b are attached to the lower portions of the brackets 531a and 531b. Yes. Also, the height direction mounting positions of the first connecting rollers 532a and 532b and the second connecting rollers 533a and 533b to the brackets 531a and 531b are different, and the first connecting rollers 532a and 532b are the second connecting rollers 533a and 533b. It is arranged at a higher position.

  Next, the receiving members 550 and 560 that are other members constituting the interlocking device 500 will be described. FIG. 8 is a perspective view of the receiving member 550 arranged on the outdoor view side of the pair of receiving members 550 and 560. In FIG. 8, when the receiving member 550 is disposed on the fire shutter 100, the lower left side of the paper is the side far from the connection arm 510, and the upper right side of the paper is the side near the connection arm 510. Further, the upper left shutter on the paper surface, and the lower right on the paper surface is the outdoor side. The receiving member 550 includes a base body 551 and a receiving groove 552 that are integrally formed. The base 551 is a flat member. The receiving groove 552 is a member that protrudes from one surface 551a of the base body 551 and has a form such that a member having an L-shaped cross section is bent. One end of the portion 552a in the L-shaped cross section is attached in contact with the surface 551a of the base 551, and the other portion 552b is disposed not in contact with the base 551. Thus, the receiving groove 552 forms a portion like a groove with the portion 552a as the bottom between the surface 551a of the base 551 and the portion 552b. Further, the receiving groove 552 is formed on the surface 551a of the base body 551 from the side far from the connecting arm 510 (the left side in the drawing) in the following manner. First, it is disposed substantially vertically below the upper part of the base 551 far from the connection arm 510, bends substantially at a right angle at the substantially central position in the vertical direction of the base 551, and extends in the direction approaching the connection arm 510 in a horizontal posture (right side of the drawing). Is done. Further, the base 551 is bent and extended vertically downward at a position slightly closer to the connecting arm 510 than the center in the horizontal direction. Further, it is bent and extended horizontally in a direction approaching the connecting arm 510, and further extended obliquely upward at an end portion of the base 551 near the connecting arm 510. With the above configuration, the receiving groove 552 has two horizontal groove portions having different heights, and two concave portions are formed. As will be described later, the first connecting roller and the second connecting roller are connected to each of the two concave portions.

  The other receiving member 560 of the pair of receiving members 550 and 560 is symmetrical with respect to the surface of the receiving member 550 on which the receiving groove 552 is not provided (not shown as a blind spot in FIG. 8). The other configurations are formed in the same shape as the receiving member 550.

  By using the interlocking device 500 as described above, the shutter 300 and the vertical portion 400 can be interlocked appropriately and reliably. Next, the relationship between the interlocking device 500 and other members will be shown and the operation will be described. The arrangement of the interlocking device 500 is as shown in FIG. 1 when viewed indoors, but FIG. 9 shows an enlarged view focusing on the interlocking device 500 and its periphery for the sake of explanation. A rotation support member 511 of the connection arm 510 is rotatably attached to the upper portion of the vertical portion 400. At this time, although not visible in FIG. 9, the connecting arm 510 and the upright portion 400 are rotated by passing a shaft having a diameter smaller than the holes 512 and 512 through the holes 512 and 512 (see FIG. 7) of the rotation support member 511. Mounted movably.

  On the other hand, the connecting portion 530 is provided on the other end side of the connecting arm 510 as described above. As shown in FIG. 7, the connecting portion 530 includes a pair of brackets 531a and 531b and first and second connecting rollers 532a, 532b, 533a and 533b, and a predetermined interval is secured. As shown in FIG. 9, the end portion of the shutter 300 is sandwiched between the predetermined intervals. As described above, the interval between the connecting portions 530 communicates with the opening 514 and the hollow portion 513 of the connecting arm 510. Accordingly, with the closing of the shutter 300 and the movement of the vertical portion 400, the end of the shutter 300 is accommodated in the hollow portion 513 through the opening 514 of the connecting arm 510, and the opening 514 and the hollow portion 513 serve as guide rails. This restricts the end of the shutter 300 from moving inward and outward when the shutter 300 is closed.

  The shutter 300 and the connecting portion 530 are connected through receiving members 550 and 560. The pair of receiving members 550 and 560 are attached to both sides of the shutter 300 at the end near the connecting arm 510 below the shutter 300. At this time, the surface where the receiving grooves 552 and 562 are not provided is arranged in contact with the shutter 300. Since the receiving members 550 and 560 have the receiving grooves 552 and 562 as described above, the first connecting rollers 532a and 532b or the second connecting rollers 533a and 533b are connected to the receiving grooves 552 and 562. The part 530 and the receiving members 550 and 560 are connected, and as a result, the connecting arm 510 and the shutter 300 are connected.

  With the arrangement of each member as described above, the vertical portion 400 and the shutter 300 are connected to each other, and when the shutter 300 is closed, the vertical portion 400 moves so as to approach the shutter 300. Move in the direction.

  Next, an operation when the vertical portion 400 moves as the shutter 300 is lowered and a change in the state of the connecting portion 530 and the receiving members 550 and 560 at that time will be described with reference to FIGS. 10, 11, and 12. To do. 10, 11, and 12, (a) of each drawing is a front view of the fire shutter device 100 as viewed from the outside, and (b) of each drawing shows the connection portion 530 and the receiving member 550 at that time. It is the figure which expanded and showed this relationship. When the fire shutter device 100 is open during normal times, the state is as shown in FIG. 10, the shutter 300 is stored in the upper part of the fire shutter 100, and the vertical portion 400 is disposed close to the wall. At this time, the interlocking device 500 is accommodated horizontally above the fire shutter device 100. Further, as shown in FIG. 10B, the connecting portion 530 and the receiving member 550 are formed of the recess 552 c of the receiving groove 552 of the receiving member 550 in which the second connecting rollers 533 a and 533 b are attached to both surfaces of the shutter 300. They are connected by engaging with each other.

  Next, when there is a fire notification or the like and the shutter 300 starts to descend, as shown in FIG. 11, the connecting arm 510 is connected to the receiving members 550 and 560 by its own weight, and the mounting portion with the vertical portion 400 is used as an axis. It is rotated counterclockwise. Since the connecting arm 510 does not change its length, when one end of the connecting arm 510 on the shutter 300 side is moved downward by this rotation, the other end is fixed to the upper portion of the upright portion 400. It cannot be changed. As a result, the end of the connecting arm 510 on the side attached to the vertical portion 400 moves to the left in the drawing, and accordingly, the vertical portion 400 is drawn toward the shutter 300. Since the connecting arm 510 pulls the vertical portion 400 while changing the angle, the first connecting rollers 532a and 532b come into contact with the receiving groove 552 in the middle when the shutter 300 is closed to some extent.

  Here, the connection arm 510 has been shown to have one end lowered by its own weight. However, the connection arm 510 may include a mechanism or member for maintaining the connection portion 530 and the receiving members 550 and 560 in a more firmly connected state. For example, a mechanism for applying a force for pressing the connection arm 510 downward, a lock mechanism for connection, and the like can be given. It is preferable to employ a suitable method depending on the material used for the interlocking device 500 and the vertical portion 400, the size of the fire prevention shutter device 100, and the like.

  When the closing operation further proceeds, as shown in FIG. 12, the vertical portion 400 reaches a predetermined position, and the connecting arm 510 becomes substantially vertical. At this time, the connecting arm 510 is housed inside the vertical portion 400 and prevents the end of the shutter 300 from shaking as a guide rail of the shutter 300 as described above.

  In the state shown in FIG. 12, the shutter 300 has not yet been closed. Therefore, when the closing operation of the shutter 300 further proceeds, as shown in FIG. 13, the connecting portion 530 is detached from the receiving members 550 and 560, and the shutter 300 can continue and complete the closing operation. Since the connecting portion 530 can be separated from the receiving members 550 and 560 in this way, the interlocking device 500 is set without necessarily matching the descending distance required for completing the passage closing of the shutter 300 and the length of the arm 510. be able to. Therefore, it is possible to provide a fire shutter device that can cope with various sizes of openings and has excellent versatility.

  Next, the operation when the shutter 300 moves from the closed state to the open state will be described. About operation | movement, it is performed so that the closing operation | movement of the shutter 300 mentioned above may be traced. This will be described with reference to FIGS. 10 to 13 in the same manner as the closing operation. When the shutter 300 starts to be opened from the closed state of the shutter 300, a state as shown in FIG. 13 is first obtained. In this state, the interlocking part 530 and the receiving members 550 and 560 are still in the detached state.

  When the shutter 300 is further opened, as shown in FIG. 12, the interlocking unit 530 and the receiving members 550 and 560 are connected again. At this time, the first connecting rollers 532a and 532b first contact the receiving groove 552. The first connection rollers 532a and 532b are provided at a position farther in the horizontal direction than the rotation fulcrum attached to the vertical portion 400 of the connection arm 510 than the second connection rollers 533a and 533b. As a result, the first connecting rollers 532a and 532b can obtain many moments and can start the movement of the vertical portion 400 more smoothly.

  When the shutter 300 is further opened, the state shown in FIG. 11 is obtained. In this state, the connecting arm 510 changes its angle as the shutter 500 is raised, and accordingly, the vertical portion 400 moves to the wall side. At this time, the connecting roller in contact with the receiving groove 553 is switched from the first connecting rollers 532a and 532b to the second connecting rollers 533a and 533b according to the angle change of the connecting arm 510. The second connection rollers 533a and 533b are arranged at positions closer to the connection arm 510 than the first connection rollers 532a and 532b. Accordingly, when the shutter 300 as shown in FIG. 10 is housed, the connecting arm 510 can be pushed upward, and the connecting arm 510 can be suitably housed in the upper part of the fire prevention shutter device 100.

  Through the series of operations described above, as the shutter 300 is opened and closed, the vertical portion 400 can move from the wall side to the end of the shutter 300 and can return to the wall side again.

  Next, the pulling mechanism 600 will be described. As shown in FIG. 1, a guide rail 630 is provided from the center of the vertical portion 400 in the height direction to the bottom. The guide rail 630 is arranged so that the guide rail at the end of the shutter 300 is formed continuously from the connecting arm 510 in a state where the connecting arm 510 is in a vertical posture and is housed inside the vertical portion 400. . The guide rail 630 is a guide rail for preventing the end of the shutter 300 from swinging inward and outward when the connecting arm 510 and the receiving members 550 and 560 are detached as shown in FIG.

  The drawing mechanism 600 will be described with reference to FIGS. 14 and 15. FIG. 14 is a perspective view of an outdoor view focusing on the pulling mechanism and its periphery. FIG. 15 is a front view of an outdoor view showing the drawing mechanism and its surroundings. As will be described later, a part of the pulling mechanism 600 is provided inside the guide rail 630. Therefore, in FIG. 15, the guide rail 630 is shown in a broken surface. The pulling mechanism 600 includes a shutter side member 610 and a rail side member 631. The shutter side member 610 has a base 611 and a pulling roller 612 and is attached to the lower end portion of the shutter 300 on the side close to the vertical portion 400. The base 611 is attached directly in contact with the shutter 300, and the pulling roller 612 is attached to the base 611 as a vertical wheel and is rotatable. On the other hand, the rail side member 631 is provided inside the guide rail 630 as shown in FIG. The rail-side member 631 is a member on a plate having a width in front and back in FIG. 15, and this is integrally formed inside the guide rail 630. Moreover, the rail side member 631 has the inclination part 631a and the vertical part 631b, as shown in FIG.

  As the closing of the shutter 300 proceeds and the connecting arm 510 approaches a substantially vertical state as shown in FIG. 12, the end of the shutter 300 is inserted into the side while being guided by the vertical portion 400. At this time, as indicated by the straight arrows in FIG. 14, the pulling roller 612 enters the inside of the guide rail 630 and contacts the inclined portion 631 a of the rail side member 631. Thereafter, as shown by a broken line in FIG. 15, the pulling roller 612 rolls on the rail side member 631. At this time, the pulling roller 612 rolls on the inclined portion 631a, whereby the shutter 300 strongly pulls the vertical portion 400. Then, by rolling on the pulling roller 612 vertical portion 631b, the shutter 300 can be moved up and down while maintaining the state in which the shutter 300 and the vertical portion 400 are strongly attracted. Accordingly, the vertical portion 400 can be reliably pulled toward the shutter 300 side, and can be maintained in a state of being strongly connected to the shutter 300 even after being pulled, and the fire protection shutter can be reliably closed as a whole. Conversely, when the shutter 300 is raised, the above operation is performed while going back.

  Next, the closing operation adjusting mechanism 700 will be described with reference to FIGS. FIG. 16 is a view showing the operation of the closing operation adjusting mechanism 700 at the same time as the door 200 and the vertical portion 400. FIG. 16A is a view showing a state where the closing operation adjusting mechanism 700 is operating during the closing operation, and FIG. 16B is a view showing a state where the closing operation is completed. FIG. 17 is an enlarged plan view showing the closing operation adjusting mechanism 700, the vertical portion 400, and the door tips of the door 200 from the indoor side when the closing operation is completed. FIG. 18 is a perspective view showing a state in which the closing operation adjusting mechanism 700 is operating.

  A closing operation adjusting mechanism 700 is attached to a portion of the upper frame 10 corresponding to the door tip when the door 200 is closed. The closing operation mechanism 700 includes an attachment base 710 attached to the surface of the upper frame 10 on the door 200 side. A stopper 730 is rotatably attached to the mounting base 710 via a shaft 720. The stopper 730 is directed in the direction of the door 200 whose front end is closed during normal times. When the door 200 is closed, the front end of the stopper 730 comes into contact with the door 200, and the door 200 is further closed. regulate.

  The vertical portion 400 is provided with an overhanging portion 405 that protrudes toward the door 200, and a contact bar 406 that protrudes upward is attached to the upper surface of the overhanging portion 405.

  In FIG. 16, as apparent from FIG. 16A, the closing operation of the door 200 is restricted by the stopper 730, so that the movement of the vertical portion 400 in the shutter direction is performed without any restriction. When the vertical portion 400 moves in the shutter direction from the wall side (moves from right to left in the figure), the contact bar 406 presses the stopper 730 that restricts the closing of the door 200, and the stopper 730 is moved to the shaft 720. Rotate around counterclockwise. Thus, the restriction on the closing of the door 200 by the stopper 730 is released, and the door 200 can be rotated to a position parallel to the upper frame 10 to complete the closing.

  FIG. 19 is a view showing the operation of the fire shutter device 100 of the present invention, where (a) is in an open state (normal time), (b) is in the middle of closing, and (c) is a state in which it is completely closed. is there. Moreover, the upper stage of each figure is a front view in outdoor view, and the lower stage shows a top view. During normal times, the shutter 300 is wound around a winder 330 provided in the ceiling, and the door 200 and the vertical portion 400 are arranged near or along the wall on the right side of the passage. Therefore, since there is nothing that obstructs the passage of the passage, it is possible to use the passage extensively. Further, since the interlocking device 500 is arranged so as to be covered in the ceiling, the presence of the interlocking device 500 hardly stands out from the outside, and the appearance of the ceiling portion can be made clear.

  When a fire or the like occurs and the fire shutter device 100 needs to be closed, the locking device that has wound the shutter 300 around the winding device 330 and is released is released, and the shutter 300 starts to descend due to its own weight. On the other hand, the connecting arm 510 of the interlocking device 500 housed in the ceiling portion is rotated counterclockwise as the shutter 300 is lowered, and the vertical portion 400 starts moving from the wall side to the shutter side so as to be pulled. . Simultaneously with these operations, the closing operation of the door 200 is also started. Finally, as shown in FIG. 19 (c), the vertical portion 400 is arranged between the fully closed shutter 300 and the door 200. As described above, since the closing operation of the shutter 300, the vertical part 400, and the door 200 proceeds simultaneously in an emergency, it does not take much time to change from the normal state to the complete closed state.

  In the above description, for example, FIG. 1 illustrates an example in which the door is disposed on the left side of the opening and the shutter is disposed on the right side. However, the arrangement of the door and the shutter may be reversed to the left and right in this example.
