Description

  The present invention relates to an earthquake countermeasure door.

  In recent years, the Japanese archipelago is said to have entered an active period, and earthquakes are frequently occurring throughout the country. As is well known, many people are killed and injured and many buildings are damaged during a large earthquake. As people living in earthquake countries, we must always be prepared for earthquakes.

  When a house is damaged due to an earthquake, the door frame may be deformed and the door cannot be opened or closed. Rescue is delayed because the door cannot be opened because the door does not open, and in the worst case, it can be burned to death by being caught in a fire that has occurred, or it can be overwhelmed by the collapse of a building caused by an aftershock.

  In order to prevent such a situation, many inventions and devices have been made. One of the measures is to prevent the deformation of the door and the door housing frame by providing springs on the top and bottom and / or left and right of the door to absorb the destructive force caused by the earthquake (Japanese Utility Model Sho 61-). No. 65190, JP-A-9-189174, JP-A-10-184218, JP-A-10-280821, etc.).

Japanese Utility Model Publication No. 61-065190 JP 09-189174 A JP-A-10-184218 Japanese Patent Laid-Open No. 10-280821

  In each said patent document, the spring is provided between the door and the door accommodating frame, and the destructive force by an earthquake is absorbed. Patent Documents 1 and 2 absorb the vertical force of the door, and Patent Documents 3 and 4 absorb the vertical and horizontal force of the door.

  These conventional devices only need to function well, but depending on the magnitude of the earthquake and the strength of the spring, it is expected that the purpose may not be sufficiently achieved. In such a case, it is advantageous if the door and the door housing frame can be artificially opened.

  An object of the present invention is to allow a door to be opened by artificially opening a gap between the door and the door housing frame when the door housing frame is deformed after the earthquake and cannot be opened or closed. Is to provide such earthquake countermeasure doors.

  The present invention includes an upper arm 11 having means that can be expanded and contracted in the vertical direction, a lower arm 12 having means that can be expanded and contracted in the vertical direction, and a means that can expand and contract in the left and right direction. A door main body having a door toe fence 13 having a central control section 2 having a rotary plate 21 provided on the door main body, the rotary plate 21, the upper rod 11, the lower rod 12.

  Preferably, the stopper 27 for stopping the rotation of the rotating plate at an appropriate position is a V-shaped recess provided in the rotating plate 21 (Claim 5).

  Preferably, the means for allowing the upper and lower heels and the door toe to be expanded and contracted includes slits 113 and 133 provided in each, and springs 115 and 135 provided across the slits 113 and 133, respectively. The inner plates 114 and 134 on which the slits slide are formed (claim 6).

  Preferably, the rope 33 on the door end side is divided into two to avoid collision with the lock (claim 7).

  Preferably, a plurality of balance devices 6 are provided so as not to lose the balance and tilt when the upper rod 11, the lower rod 12, and the door rod 13 are pulled (Claim 8).

  Preferably, each of the balance devices 6 includes a spring 62 built in the main body 61 and a head 63 that constantly presses the upper rod 11, the lower rod 12, and the door-end rod 13 by the spring 62. (Claim 9).

  According to the first aspect of the present invention, by rotating the rotary plate 21 of the central control unit 22, the ropes 31, 32, 33 are drawn and the upper rod 11, the lower rod 12, and the door-end rod 13 are moved. It can be pulled toward the door center. In this state, the vertical and horizontal dimensions of the door are shortened, so that the door can be easily opened even from the deformed door housing frame.

  Claims 2 to 7 show preferred embodiments of the present invention.

  Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

It is (a) side view and (b) front view of the earthquake countermeasure door which concerns on the Example of this invention, and has shown the state which removed the surface plate. It is the (a) side view and (b) front view of the earthquake countermeasure door which show the operation principle of the Example, and has shown the state which removed the surface plate. It is AA sectional drawing of FIG. It is (a) front view, (b) side view, (c) bottom view, (d) rear view of the central control part which concerns on the Example. FIG. 5 is a cross-sectional view taken along a line CC in FIG. 4, (a) when fixed, and (b) when rotating. It is sectional drawing of DD of FIG. 4, (a) is at the time of fixation, (b) is at the time of rotation. It is the (a) front view before rotation of the central control part which concerns on the Example, (b) The front view after rotation. It is BB sectional drawing of FIG. 1, (a) Before operation | movement, (b) After operation | movement.

  As shown in FIG. 1, an earthquake countermeasure door 1 is attached to a door housing frame (not shown) by a hinge 5. An anti-seismic hinge may be used as the hinge 5, but in the present embodiment, the anti-seismic hinge is not necessarily required, and a general-purpose hinge may be used.

  In the earthquake countermeasure door 1 of the present embodiment, a central control unit 2 having a rotating plate 21 is fixed at the center of the door. Rope 31, 32, and 33 are stretched from the rotating plate 21 in three directions, ie, upper door 11, lower rod 12, and door rod 13. On the door rod 13 side, when it goes straight, it hits a lock (not shown), so it is stretched in two parts to avoid it.

  As shown in FIG. 2, when the rotating plate 21 is rotated, the ropes 31, 32, and 33 are pulled, and the upper rod 11, the lower rod 12, and the door rod 13 move toward the central control unit 2. Therefore, gaps 112 and 134 are formed between the door 1 and the door housing frame (not shown).

  Before rotating the rotating plate 21, it is of course necessary to unlock it. If the door is locked, the door end side rope 33 cannot be pulled, and the rotating plate 21 cannot rotate. Therefore, neither the upper side rope 31 nor the lower side rope 32 can be pulled.

  As shown in FIG. 3, the rotating plate 21 of the central control unit 2 is installed on a fixed plate 28 attached to the back surface of the surface plate 14 on the outdoor side of the door 1. An opening 16 for inserting a tool such as the socket wrench 4 is provided in the surface plate 15 on the indoor side. In the present invention, in order to artificially open the door, it is preferable to keep such a tool around the entrance.

  As shown in FIGS. 4 and 5, the rotating plate 21 has a prismatic protrusion 22 at the center. Long holes 23 are provided at four locations around the protrusion 22 to form four divided arcs.

  A first pin 24 is fixed to the fixed plate 28 by spot welding in each elongated hole 23. A spring 244 is set between the first pin head 242 and the washer 243 on the rotating plate, and can be expanded and contracted on the first pin main body 245.

  Three edges of the second pin 26 are fixed to the edge of the rotating plate 21, and the ropes 31, 32, 33 are fixed to the second pin 26. As described above, the three ropes are directed in the three directions of the upper arm 11, the lower arm 12, and the door toe 13 of the door, and maintain the tension state at the end portions 111, 121, 131, 132 (FIG. 1). To be fixed. It is preferable to provide a rope slack eliminating mechanism so that the tension state does not relax.

  The rotating plate 21 is further provided with a stopper 27 so that it does not rotate during normal times and stops at the rotation end position. As shown in FIG. 6, the stopper 27 of the rotating plate 21 is a recess having a V-shaped cross section. When the V-shaped projection 271 is engaged with the slit 141 or the depression of the door surface plate, the position of the rotating plate 21 is fixed (FIG. 6B).

  As shown in FIG. 3, when the socket 41 of the socket wrench 4 is inserted into the protrusion 22 through the opening 16 and the protrusion 22 is rotated, the stopper 27 is removed as shown in FIGS. 5B and 6A. Due to the mountain-shaped protrusion 271, the rotating plate 21 is slightly lifted and can be rotated. The rotating plate 21 moves from the state shown in FIG. 7A to the state shown in FIG. The rotation angle is about 25 degrees.

  Since the rope is stretched in a tension state, as shown in FIG. 2, the upper rod 11, the lower rod 12 and the door rod 13 of the door 1 move toward the center of the door, and between the door 1 and the door housing frame. The gaps 112 and 134 are formed. About 5 mm is sufficient for each gap.

  When the upper rod 11, the lower rod 12, and the door rod 13 proceed toward the center of the door, there is a risk that the balance will be lost if nothing is done. In order to prevent this, as shown in FIGS. 1 and 2, two balance devices 6 are attached in the vicinity of the upper rod 11, the lower rod 12, and the door rod 13. In the balance device 6, a spring 62 is built in a main body 61, and the spring 62 always presses each head lightly against the head 63. The pressing force should not be stronger than the pulling force of the rope.

  When the rotating plate 21 is rotated, the upper and lower doors 11, 12, and 13 of the door are shortened in size, so that space must be secured in the door. For this purpose, as shown in FIG. 8, the door plates of the upper ridge 11, the lower ridge 12 and the door-end ridge 13 are provided with slits 113 and 133 near the corner portion. Slide along 114,134. In order to keep the slits 113 and 133 open during normal times, springs 115 and 135 are set so as to straddle the slits.

  When the rotating plate 21 is rotated about 25 degrees, the state shown in FIGS. When the rotating plate 21 comes to the stopper position, the rotation stops, and the spring 244 causes the mountain-shaped protrusion 271 to enter the slit 144 and be fixed. As a result, the upper rod 11, the lower rod 12, and the door rod 13 are maintained in a state where the dimensions are shortened. In this state, since the door 1 is separated from the door housing frame, the door can be opened.

  It should be noted that if the upper rod 11, the lower rod 12, and the door rod 13 are completely fixed to the door surface plate, the size of the door cannot be shortened, so these rods must be able to move freely. . Further, since the door surface plate itself should not hinder the opening and closing of the door, the size is preferably set to the size when the door is the smallest. Even when the door is the smallest, it is only about 5 mm shorter at the top, bottom, and left of the door, so there is little loss of aesthetics or weakness.
