Description

  The present invention relates to a door that has improved water resistance when immersed in a steel door.

  Steel doors used in conventional buildings are provided with the following four sections according to their closing performance. The first category is a normal steel door category, which does not take any action in the gaps between the joinery frame and the shoji, or the summons of the shoji, and has a closing property such as air and sound. It is a section of the door that does not. The second category is a semi-air tight door category. Airtight material made of chloroprene rubber, etc. is incorporated between the joiner frame and the shoji and between the shojis to ensure a certain level of airtightness when the door is closed. This is the door category.

  The third section is an airtight door section, and the above-described semi-airtight door is further provided with a protrusion that bites into the airtight material when the door is closed, and a lock mechanism that presses the shoji itself or the shoji and the fixture frame is provided. It is a division of a door (for example, refer to patent documents 1). The fourth category is a watertight door category, with a watertight packing to ensure watertightness when the door is submerged, and a door type with a shoji screen and frame that is reinforced to withstand water pressure. It is.

  The normal steel door of the first section is provided in the building where airtightness and sound insulation are not required. The semi-air tight door of the second section is often provided where a certain level of sound insulation is required.

  The airtight door of the third section is provided in a place where the airtightness is required in addition to the sound insulation, and is mainly an important room that directly touches the outside air. The airtight door is the door that is frequently used as an external fitting because it has the highest closing performance among the doors that are generally used.

  Compared to the doors of these sections, the specifications of the watertight doors of the fourth section are greatly different, and most of them are relatively small because they need to withstand water pressure. For this reason, the watertight door is mainly used only in places where water tightness such as an electric power room is strongly required, and is used less frequently than the airtight door.

JP 2011-094332 A

  As described above, an airtight door that is frequently used as an external joinery may be destroyed by water pressure when submerged, even if the airtightness can be secured. Specifically, there have been cases in the past where airtight doors were submerged and destroyed by flooding and tsunami.

  Specifically, when the air tight door is submerged, the water pressure applied to the air tight door is greatest at the lowermost portion and becomes smaller as it goes upward. For example, when the air tight door is a double-open door, deformation is restrained at the edge of the shoji (door main body) supported by the joinery frame, and deformation due to water pressure occurs at the central portion of the door main body. More specifically, since the water pressure increases as it goes downward as described above, the deformation of the portion slightly below the center portion is the largest.

  If this deformation becomes even larger, the fitting of fixed handles such as a lock mechanism such as a gremon lock provided at the center of the air tight door's summoning part or a lock mechanism provided at the lower part of the air tight door may be destroyed. Dropouts occur. Then, the deformation of the door main body that has lost the fixing force by the lock mechanism further proceeds, a breakage occurs in the summing portion of the air tight door, and the destruction of the entire door proceeds at once.

  In order to prevent such door destruction, it is first considered to replace the airtight door with a watertight door. However, replacement with a watertight door has a problem that replacement parts are large and the replacement work is complicated, and that a large amount of cost is required. Furthermore, as described above, there is a limitation due to the difference in dimensions between the airtight door and the watertight door, and thus there is a problem that even if replacement is performed, it may not be suitable for actual operation.

  The present invention has been made in order to solve the above-mentioned problems, and it is easy to improve the water resistance performance of a door that has airtightness, such as an air tight door, but has insufficient water resistance performance. It aims at providing the door which can do.

In order to achieve the above object, the present invention provides the following means.
The door of the present invention has a pair of doors supported so as to be openable and closable with respect to the door frame, and a rotation shaft fixed to a door tip portion of the indoor side surface of one of the pair of doors. A rod-shaped swivel portion, one end of which is supported, and a door-end portion on the interior side surface of the other of the pair of door bodies, and the other end of the swirl portion are fitted together. And holding the other end of the pinion portion in a state of being arranged above the rotating shaft and the receiving portion, and at least the other door tip portion of the pair of door bodies. And an engaging portion that releases the holding of the other end portion of the hinge portion when the center protrudes toward the indoor side.

  According to the door of the present invention, when the door body is bent so as to protrude indoors due to water pressure or the like, the retaining portion is released from the locking portion, and the other end portion of the retaining portion is connected to the receiving portion. Fitted together. Since the pair of door bodies has their door tips fixed by the yoke and the receiving portion, the resistance to water pressure is higher than when the fitting and the receiving portion are not fitted together. .

  In addition, since the locking portion holds the other end of the yoke portion at a position higher than the rotation shaft and the receiving portion, when the holding is released, the other end portion of the yoke portion is caused by gravity. It falls toward the receiving part and is fitted.

  Moreover, since the water-resistant performance of the door can be improved by adding the yoke portion, the receiving portion, and the locking portion, the water-resistant performance can be added to a door such as an existing airtight door. In other words, it is possible to easily take measures against submergence on the existing door.

  Compared with the case where the door body is replaced to improve the water resistance performance of the door, only the bolted portion, the catching portion and the locking portion are added, so the cost required for improving the water resistance performance can be suppressed. In addition, the work necessary for improving the water resistance performance is simplified. In addition, since there is no change in the basic structure of the door, it is difficult to cause trouble in the normal operation of the door.

  In the above invention, the locking portion is a locking convex portion and a locking concave portion that are fitted together, and one of the locking convex portion and the locking concave portion is provided at the other end of the pinning portion. It is preferable that the other of the locking projection and the locking recess is provided on a door body provided with the rotation shaft.

  By configuring the locking portion from the locking projection and the locking recess in this manner, the distance between the locking projection and the locking recess is increased when the door body is curved so as to protrude indoors. The fitting between the two is solved. As a result, the other end of the yoke is dropped and fitted toward the receiving part.

  In the above invention, the locking part is an adsorbing part and an adsorbed part that adsorb each other by a magnetic force, and one of the adsorbing part and the adsorbed part is provided at the other end of the yoke, and the adsorbing part It is preferable that the other of the part and the attracted part is provided on a door body provided with the rotation shaft.

  By configuring the locking portion from the suction portion and the portion to be sucked in this way, when the door body is curved so as to protrude into the indoor side, the distance between the suction portion and the portion to be sucked is increased and the two are separated from each other. The working attractive force is weakened. When the force at which the other end portion of the yoke portion drops is larger than the attracting force, the other end portion of the yoke portion moves toward the receiving portion and is fitted together.

  In the above invention, the engaging portion is an attracting portion that is attracted to the magnetic material by magnetic force, and the attracting portion is provided on the other end portion of the hinge portion and one of the door bodies provided with the rotating shaft. In addition, it is preferable that at least the other end portion of the yoke portion and at least the other of the door body provided with the rotation shaft have a portion formed of the magnetic material that is adsorbed by the adsorption portion.

  Thus, by providing an adsorbent body in one of the yoke and the door body, and at least the other of the yoke section and the door body is provided with a portion formed of a magnetic material that the adsorber adsorbs, thereby the door body is When it curves so as to protrude to the indoor side, the distance between the attracting portion and the portion formed from the magnetic material is increased, and the attracting force acting between the two is weakened. When the force at which the other end portion of the yoke portion drops is larger than the attracting force, the other end portion of the yoke portion moves toward the receiving portion and is fitted together.

  In the above invention, the outer surface of the door body is provided with a deformation suppressing portion that extends from the door tip portion toward the suspension base portion and protrudes to the outdoor side of other portions, and each of the pair of door bodies. A gap is formed between the end portions on the door tip side of the deformation suppressing portion provided on the door, and the door tips of the deformation suppressing portion are deformed when the door tip portions of the pair of door bodies are deformed to the indoor side. The side ends are preferably in contact with each other.

  By providing such a deformation suppression part, the tolerance with respect to the water pressure of a door body becomes high. That is, by providing the deformation suppressing part that at least partially increases the thickness of the door body, the strength of the door body alone is increased and the resistance to water pressure is increased. Further, when the door body protrudes into the room and curves, the end portions on the door tip side of the deformation suppressing portion come into contact with each other, so that the pair of deformation suppressing portions are integrated to function like a crown. The strength of the door body increases, and the resistance to water pressure increases.

  According to the door of the present invention, when the door body is bent so as to protrude indoors due to water pressure or the like, it is possible to easily improve the water resistance performance by providing the yoke portion and the receiving portion that are fitted together. There is an effect that can be done.

  The hinge portion 12 is a hinge member provided on each of a pair of frames extending in the vertical direction in the door frame 11, and supports the door bodies 13a and 13b so as to be opened and closed. As shown in FIG. 3, the hinge portion 12 is disposed so as to protrude from the door frame 11 to the outdoor side (the front side of the paper surface of FIG. 1A). In this embodiment, the door body 13a and the door body 13b will be described as applied to an example in which the door body 13a and the door body 13b are supported by three hinge portions 12 arranged in the vertical direction.

  The door bodies 13a and 13b are members formed in a pair of plates that are supported by the hinge portion 12 so as to be opened and closed. The door body 13a and the door body 13b are respectively arranged on the right half and the left half of the opening of the door frame 11 when viewed from the outside of the building body. As will be described later, a lock portion 15 and the like are attached to the door bodies 13a and 13b.

  The lock portion 15 is for fixing the door bodies 13a and 13b in a closed state. As shown in FIG. 1 (b), for example, the lock portion 15 is arranged on the door-end side on the indoor side surface of the door body 13b. It is. The lock portion 15 includes a portion that fixes the door body 13a or the door body 13b between the door frame 11 and a portion that fixes the door portion 13a and the door body 13b at the summing portion 14.

  Lock portions 15 for fixing the door body 13a or the door body 13b between the door frame 11 are arranged at two locations near the upper end and the lower end of the door body 13a or the door body 13b. The lock portion 15 to be fixed between the door body 13a and the door body 13b is disposed at substantially the center of the end on the door end side of the door body 13b.

  The lock portion 15 is mainly composed of a grip portion 15B and a rod 15C that rotate around a lock shaft 15A provided perpendicular to the door body 13a, and a fitting portion 15D into which the tip of the rod 15C is fitted. Yes. The format of the lock unit 15 is not limited to the above format, and other known formats can be used.

  Next, the yoke part 20, the receiving part 30, and the latching part 40 which are the characteristics of this embodiment are demonstrated. As shown in FIGS. 1 and 2, the yoke 20 and the receiving part 30 are arranged at substantially the center on the indoor side surface of the door bodies 13 a and 13 b, and the door bodies 13 a and 13 b protrude indoors due to water pressure or the like. When it curves, it fits together and raises the intensity | strength of a pair of door bodies 13a and 13b.

The yoke portion 20 is rotatably attached to the door body 13a and is fitted to the receiving portion 30 provided on the door body 13b.
As shown in FIGS. 3 (a) and 3 (b), the yoke 20 has a yoke main body 21 that is a rod-shaped member formed in a square column shape, and a rotary shaft 22 that rotatably supports the yoke main body 21. And mainly consists of. In the present embodiment, the yoke main body 21 is described as being applied to an example of a rod-shaped member formed in a quadrangular prism shape, but is not limited to a quadrangular prism shape, and those formed in other shapes are also used. Can do.

  A through hole 23 through which the rotary shaft 22 is inserted is provided at one end of the yoke main body 21, and the other end is a groove-like recess that becomes a part of a locking portion 40 described later. A recess 42 is provided.

  The rotary shaft 22 is attached in the vicinity of the center in the vertical direction of the door tip portion of the door body 13a so that the axis is always perpendicular to the indoor side surface of the door body 13a. The rotary shaft 22 is mainly composed of a columnar or cylindrical shaft body 24 inserted through the through-hole 23 and a flange portion 25 that rotatably holds the yoke body 21 between the door body 13a. Yes. In the present embodiment, the shaft body 24 is fixed to the protruding portion 26 formed on the door body 13 a, and after the shaft body 24 is inserted into the through hole 23 of the main body 21, the flange portion 25 is attached to the shaft body 24. The explanation is applied to an example.

  The receiving part 30 is provided in the door body 13b different from the door body 13a in which the yoke part 20 is provided, as shown in FIGS. Moreover, the receiving part 30 is a door-end part in the above-mentioned another door body 13b, and is provided in a range in which the main body 21 reaches in the lateral direction from the rotating shaft 22 in the front part 20. The receiving portion 30 is formed in an L shape including a protruding portion 31 extending from the door body 13 b toward the indoor side and a guide portion 32 that bends upward from the end portion of the protruding portion 31.

  The protruding portion 31 supports the guide portion 32 and also supports the main body 21 that has fallen due to gravity. The guide part 32 guides the main body 21 that has fallen due to gravity to the projecting part 31, and also holds the main body 21 supported by the projecting part 31 so as not to fall from the projecting part 31. . The guide part 32 may be arrange | positioned in parallel with respect to the surface by the side of the room | chamber interior of the door body 13b, and may be inclined and arrange | positioned in the direction away from the door body 13b toward the upper direction.

  The locking portion 40 normally holds the yoke portion 20 so as not to be fitted to the receiving portion 30, and when the door body 13a is curved so as to protrude indoors due to water pressure or the like, The holding portion 20 is released so that the yoke portion 20 and the receiving portion 30 are fitted together.

  As shown in FIG. 3, the locking portion 40 mainly includes a locking convex portion 41 provided on the door body 13 a and a locking concave portion 42 provided on the yoke main body 21. The latching convex part 41 and the latching recessed part 42 hold | maintain the yoke main body 21 by being fitted, and cancel the holding | maintenance of the yoke main body 21 by releasing fitting.

  The locking projection 41 is a door body 13 a provided with the yoke main body 21, and is provided above the rotation shaft 22. More preferably, it is provided above the vertical direction of the rotating shaft 22 or above the door end side. The locking projection 41 is a plate-like or bank-like member that protrudes from the door body 13a to the indoor side and extends in the radial direction around the rotation shaft 22, that is, the vertical direction in this embodiment. Further, the upper end portion of the locking convex portion 41 is formed so as to protrude to the indoor side from the lower end portion, and the upper end portion and the lower end portion are connected by an inclined surface.

  Thus, by making the protruding height of the lower end portion of the locking convex portion 41 lower than that of the upper end portion, it becomes easier to release the holding main body 21. That is, as shown in FIG. 3B, when the door body 13a is curved, the distance between the lower end portion of the locking convex portion 41 and the yoke main body 21 is compared with the distance between the upper end portion. Get closer. At this time, if the protruding heights of the upper end portion and the lower end portion are equal, the lower end portion is likely to be caught with the yoke main body 21, and the holding release of the yoke main body 21 may not be smoothly performed. On the other hand, by restraining the protruding height of the lower end portion, the catch between the lower end portion and the yoke main body 21 can be suppressed, and the holding main body 21 can be smoothly released.

  Further, the protruding height of the upper end portion of the locking convex portion 41 is determined by the degree of curvature of the door body 13a when releasing the holding of the yoke main body 21. That is, when releasing the holding main body 21 while the curvature of the door body 13a is small, the protrusion height of the upper end portion of the locking projection 41 is suppressed, and the curvature of the door body 13a becomes large. When the holding of the yoke main body 21 is released, the protruding height of the upper end portion of the locking projection 41 is increased.

  The locking recess 42 is an end opposite to the end provided with the through-hole 23 in the main body 21 and has a groove shape extending in the major axis direction of the main body 21 on the surface facing the door body 13a. It is the dent which can accommodate the latching convex part 41 in the inside formed.

  As described above, the locking projection 41 is a plate-like member extending in the radial direction around the rotation shaft 22, and the locking recess 42 is a groove-like recess extending in the longitudinal direction of the main body 21. Thus, it is possible to suppress a decrease in strength of the yoke main body 21. For example, if the locking recess 42 is a groove-like recess extending in the end axis direction of the punching main body 21, the force acting on the pulling main body 21 (the force acting in the shearing direction) when the pulling portion 20 is fitted to the receiving portion 30. ), The strength of the yoke main body 21 is likely to decrease. Even when the same force is applied, if the locking recess 42 is a groove-like recess extending in the major axis direction of the yoke main body 21, a decrease in strength of the yoke main body 21 is suppressed.

Next, improvement in water resistance in the waterproof door 1 having the above-described configuration will be described.
As shown in FIG. 3 (a), the waterproof door 1 of the present embodiment is fitted with the locking convex portion 41 and the locking concave portion 42 in a normal use state that is not submerged. As shown, the yoke main body 21 is held in a state extending upward from the rotary shaft 22.

  When the waterproof door 1 is submerged, the door body 13a is pressed by water pressure, and as shown in FIG. 3B, the door body 13a is curved so as to protrude to the indoor side (left side of FIG. 3B). Since the yoke main body 21 is supported by the door body 13a via the rotating shaft 22, the end portion on the side where the locking recess 42 is provided in the yoke main body 21 is separated from the door body 13a and the locking protrusion 41. Leave. By this relative movement, the engagement between the locking projection 41 and the locking recess 42 is released.

  Then, the end of the main body 21 provided with the locking recess 42 rotates around the rotation shaft 22 due to gravity, thereby dropping along the path indicated by the broken line in FIG. As shown in FIG. By fitting the crown main body 21 with the receiving portion 30, the pair of door bodies 13a and 13b are fixed integrally, and the strength of the pair of door bodies 13a and 13b against water pressure is increased.

  According to the waterproof door 1 having the above-described configuration, when the door body 13a is curved so as to protrude indoors due to water pressure or the like, the retaining portion 40 is released from being held by the locking portion 40, and the end portion of the retaining portion 20 is released. Is fitted with the receiving part 30. Since the pair of door bodies 13a and 13b has their door tips fixed by the punching portion 20 and the receiving portion 30, compared to the case where the sliding portion 20 and the receiving portion 30 are not fitted together. The resistance to water pressure can be increased.

  Moreover, since the latching | locking part 40 hold | maintains the edge part in which the latching recessed part 42 of the yoke part 20 was provided in the position higher than the rotating shaft 22 and the receiving part 30, when the said holding | maintenance was cancelled | released, The end portion of the crown portion 20 provided with the locking recess 42 falls toward the receiving portion 30 due to gravity and is fitted together. In other words, since it is not necessary to use power such as electricity, the waterproof performance of the waterproof door 1 can be improved even in an emergency such as a power failure.

  Moreover, since the watertight performance of the airtight door 10 can be improved by adding the yoke 20, the receiving portion 30, and the locking portion 40, the watertight performance can be added to the existing airtight door 10. In other words, it is possible to easily take measures against submersion of the existing airtight door 10.

  Compared with the case where the watertight performance of the air tight door is improved by replacing the door bodies 13a and 13b, only the bolting portion 20, the receiving portion 30 and the locking portion 40 are added, so that it is necessary to improve the water resistance performance. Cost can be reduced. In addition, the work necessary for improving the water resistance performance is simplified. In addition, since there is no change in the basic structure of the airtight door 10, it is difficult to cause troubles in the operation of the waterproof door 1 during normal times.

  In addition, like the above-mentioned embodiment, the latching recessed part 42 may be provided in the yoke main body 21, and the latching convex part 41 may be provided in the door body 13a, and it shows to Fig.4 (a) and FIG.4 (b). As described above, the latching main body 21 may be provided with the locking projection 41 and the door body 13 a may be provided with the locking recess 42.

  Further, as shown in FIGS. 5A and 5B, the engaging portion 40A includes an attracting portion 41A that is a magnet provided on the door body 13a, and an attracting portion 41A provided on the yoke main body 21. 42A of to-be-adsorbed parts formed from magnetic materials, such as iron attracted | sucked by magnetic force, may be comprised.

  By configuring the locking portion 40A in this manner from the suction portion 41A and the suctioned portion 42A, the distance between the suction portion 41A and the suctioned portion 42A can be increased when the door body 13a is curved so as to protrude indoors. The adsorptive power that works between them is weakened. When the force at which the end portion of the punching portion 20 falls more than the attracting force, the end portion of the punching portion 20 can be moved toward the receiving portion 30 and can be fitted together.

  Alternatively, the door body 13a may be provided with the suctioned portion 42A, and the yoke main body 21 may be provided with the suction portion 41A. In addition, instead of providing the attracted portion 42A, a region facing the attracting portion 41A in the door body 13a or the main body 21 may be formed of a magnetic material such as iron so that the attracting portion 41A can be attracted.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS.
The basic configuration of the waterproof door of this embodiment is the same as that of the first embodiment, but the configuration of the door body is different from that of the first embodiment. Therefore, in this embodiment, only the structure of a door body is demonstrated using FIG. 6 and FIG. 7, and description of other components is abbreviate | omitted.

  As shown in the perspective view of FIG. 6A and the cross-sectional view of FIG. 6B, the airtight door 110 of the waterproof door (door) 101 includes a door frame 11, door bodies 113a and 113b, and a door frame. 11 and the door body 113a, between the door frame 11 and the door body 113b, and between the door bodies 113a and 113b, mainly an airtight portion (not shown) for ensuring airtightness.

  The door body door bodies 113a and 113b are members formed in a pair of plates that are supported by the door frame 11 so as to be openable and closable. The pair of door body door bodies 113a and 113b are respectively disposed on the right half and the left half of the opening of the door frame 11 when viewed from the outside of the building body. The door bodies 113a and 113b are provided with a deformation suppressing portion 114 that suppresses deformation of the door bodies 113a and 113b when water pressure is applied.

  The deformation suppressing portion 114 is provided on the outer surfaces of the door bodies 113a and 113b in the vicinity of the center in the vertical direction and extends from the door tip portion toward the suspending portion than other portions of the door bodies 113a and 113b. Is also a portion protruding to the outside of the room. Furthermore, the deformation | transformation suppression part 114 is formed in the shape from which the protrusion height from the door bodies 113a and 113b becomes large gradually toward a door-end part from a suspension base part.

  Furthermore, a gap 115 is provided between the pair of deformation suppressing portions 114 and 114 as shown in FIG. For example, when the doors 113a and 113b are closed, the width of the gap 115 is not more than a level where a human hand is not caught between the deformation suppressing portions 114 and 114. The degree which the deformation | transformation suppression parts 114 and 114 contact after fitting to the part 30 can be mentioned.

  By providing such a deformation suppression part 114, the tolerance with respect to the water pressure of the door bodies 113a and 113b can be made high. That is, by providing the deformation suppressing portion 114 that increases the thickness of the door bodies 113a and 113b at least partially, the strength of the door bodies 113a and 113b alone is increased and the resistance to water pressure is increased. Furthermore, when the door bodies 113a and 113b protrude and curve toward the indoor side, the door-side end portions of the deformation suppressing portions 114 and 114 come into contact with each other, so that the pair of deformation suppressing portions 114 and 114 are integrated. It works like a pinch, can increase the strength of the pair of door bodies 113a and 113b, and can increase the resistance to water pressure.

  In addition, the shape of the deformation | transformation suppression part 114 may be a shape where the protrusion height from the door bodies 113a and 113b becomes large gradually toward the door-end part from the suspension part like the above-mentioned embodiment. Like the deformation | transformation suppression part 114A shown to the perspective view of Fig.7 (a), the shape from which a protrusion height does not change substantially from a hanging part to a door-end part may be sufficient. Further, the deformation suppressing portion 114 may be provided only in the vicinity of the substantially center in the vertical direction of the door bodies 113a and 113b, or the door body 114 may be substantially similar to the deformation suppressing portion 114B shown in the perspective view of FIG. You may make it all over.
