Description

The present invention relates to a building seismic device that reinforces a building by forming braces when an earthquake occurs.

It has been widely known that it is effective to provide a brace between columns as a means of preventing the building from collapsing or being damaged by an earthquake by improving the earthquake resistance of the building. However, when an opening, a door, a window, or the like is formed on the wall surface, the function of the opening or the like is hindered if the brace is provided so as to straddle the opening or the like.

As a solution to this problem, Patent Document 1 discloses a seismic device that does not form a brace in a normal time when an earthquake does not occur, but detects the brace when an earthquake occurs and forms a brace. .. The conventional device disclosed in Patent Document 1 employs an earthquake sensor in order to detect an earthquake. This seismic sensor detects the vibration of the building, and the vibration detection information is transmitted to the brace forming mechanism by wire or wirelessly (see paragraphs 0038 and 0058). That is, an electrical mechanism is adopted to detect the occurrence of an earthquake and form a brace. Therefore, if a power outage occurs due to an earthquake, the expected operation may be hindered. It is quite predictable that a power outage will occur at the same time as a large-scale earthquake occurs.

Japanese Unexamined Patent Publication No. 2009-249964

The present invention has been made in view of the above problems, and even if a power failure occurs due to the occurrence of an earthquake, the operation is not hindered, and a building seismic resistance device that forms a brace in the building at the time of an earthquake ( In the following, the purpose is to provide (abbreviated as "seismic device" as appropriate).

In order to solve the above problems and achieve the above object, the first aspect of the present invention is the seismic resistance of the building by forming a brace in a predetermined vertical rectangular region of the building at the time of an earthquake. It is a seismic resistance device for buildings, and includes a long member, a weight, a guide member, a weight locking mechanism, a locking release mechanism, and a detent mechanism. The elongated member is expandable and contractible, and one end thereof is supported on the upper portion of the vertical rectangular region on the widthwise one end side so as to be rotatable within the vertical rectangular region. The weight is connected to the other end of the long member. The guide member is installed on the other end side in the width direction of the vertical rectangular region, and guides the weight so that it can fall from the upper part to the lower part. In the weight locking mechanism, the weight is placed at a position where the height of the other end of the long member becomes a height at which the one end is supported at the upper portion of the vertical rectangular region on the other end side in the width direction. , Locks so that it can be released. The unlocking mechanism has an earthquake detection weight, and mechanically transmits the movement of the earthquake detection weight due to an earthquake with a strength exceeding the specified value so as to release the locked state of the weight. , Drives the weight locking mechanism. The detent mechanism stops the reversion of the weight when the weight is guided by the guide member and falls and reaches the lower portion. Then, the long member is stretched and contracted so as to maintain the length when the length reaches the length at which the weight is in the lower part and forms a brace in the absence of an earthquake. It has an expansion and contraction prevention mechanism to stop the.

According to this configuration, in normal times when an earthquake exceeding the regulation does not arrive, no brace is formed in the vertical rectangular region of the building, and the long member is located on the upper end side and the other end side of the vertical rectangular region in the width direction. Placed between the top of the. Therefore, when openings such as entrances and exits and windows face the vertically rectangular region, the functions of those openings are not hindered in normal times. When an earthquake exceeding the specified value arrives, the movement of the weight for detecting an earthquake accompanying the earthquake is mechanically transmitted, so that the locked state of the weight by the weight locking mechanism is released, and the weight is guided to the guide member while being guided. It falls to the lower part on the other end side in the width direction of the vertical rectangular area. As a result, the long member forms a brace in the vertical rectangular region. The fallen weight is stopped from returning by the detent mechanism, and the long member maintains the original length as a brace by the action of the expansion and contraction prevention mechanism. For this reason, the long member exerts a function as a brace formed in the vertically rectangular region, and enhances the earthquake resistance of the building. Since no electrical mechanism is required to form the brace, even if a power outage occurs due to an earthquake, the operation is not hindered. By further providing a seismic device configured symmetrically with this configuration by reversing the positional relationship in the width direction of the vertical rectangular region, the seismic resistance of the building can be further improved. In the present application, the term "bracing" is also used for only one of the pair of members diagonally arranged so as to intersect each other in the vertical rectangular region.

The second aspect of the present invention is a seismic device of a building that enhances the seismic resistance of the building by forming a brace in a predetermined vertical rectangular region of the building when an earthquake occurs, and is a long member. , A weight, a guide member, a weight locking mechanism, a locking release mechanism, and a detent mechanism. One end of the long member is supported on the upper portion of the vertical rectangular region on the widthwise one end side so as to be rotatable in the vertical rectangular region, and the long members are connected to each other so as to be rotatable in the vertical rectangular region. It has two long elements, and the other end side of the two long elements is expandable and contractible. The weight is connected to the other end of the long member. The guide member is installed on the other end side in the width direction of the vertical rectangular region, and guides the weight so that it can fall from the upper part to the lower part. The weight locking mechanism has a predetermined height at which the other end of the long member is lower than the height at which the one end is supported at the upper portion of the vertical rectangular region on the other end side in the width direction. It locks to the standby position so that it can be released. The unlocking mechanism has an earthquake detection weight, and mechanically transmits the movement of the earthquake detection weight due to an earthquake with a strength exceeding the specified value so as to release the locked state of the weight. , Drives the weight locking mechanism. The detent mechanism stops the reversion of the weight when the weight is guided by the guide member and falls and reaches the lower portion. Then, the long member has the length of the long element on the other end side that can be expanded and contracted so that the long element on the other end side is in a horizontal posture when the weight is in the standby position. Further has a length holding mechanism that holds the weight and releases the holding state when the weight falls. Further, the length element on the other end side retains the length when the length reaches the length at which the weight is in the lower part and forms a brace in the absence of an earthquake. It has an expansion / contraction prevention mechanism that suppresses expansion and contraction. Further, the long element on the other end side has an extending portion extending in the longitudinal direction beyond the connecting portion between the long element on the one end side and itself. Further, the extending portion can be overlapped with the elongated element on the one end side so as to coincide with the longitudinal direction, and the elongated member can be overlapped with the extending portion and the elongated element on the one end side. Further, it has a bending restraining mechanism that stops bending in any direction when the longitudinal directions of the above are matched and maintains a state in which the longitudinal directions are matched.

According to this configuration, in normal times when an earthquake exceeding the regulation does not arrive, no brace is formed in the vertical rectangular region of the building, and the long member is placed between one end side and the other end side of the vertical rectangular region. It is placed in an area above a predetermined height. Therefore, when openings such as entrances and exits and windows face the vertically rectangular area, by setting the predetermined height higher than those openings, the function of those openings is not hindered in normal times. Can be done. Further, in a normal state, due to the function of the length holding mechanism, the long element on the other end side is in a horizontal posture at a predetermined height lower than the height at which one end of the long member is supported. Therefore, by setting the predetermined height slightly higher than the height of the ceiling, it is possible to prevent the pipes and the like, which are often arranged behind the ceiling, from interfering with the long member. When an earthquake exceeding the specified value arrives, the movement of the weight for detecting an earthquake accompanying the earthquake is mechanically transmitted, so that the locked state of the weight by the weight locking mechanism is released, and the weight is guided to the guide member while being guided. It falls to the lower part on the other end side in the width direction of the vertical rectangular area. As a result, the long member forms a brace. The fallen weight is stopped from returning by the detent mechanism, and the long member maintains the original length as a brace by the action of the expansion and contraction stop mechanism, and the two connected members are connected by the action of the bend restraint mechanism. The bending of the long elements is restrained so that the longitudinal directions of the long elements are kept in agreement. For this reason, the long member exerts a function as a brace formed in the vertically rectangular region, and enhances the earthquake resistance of the building. Since no electrical mechanism is required to form the brace, even if a power outage occurs due to an earthquake, the operation is not hindered. By further providing a seismic device configured symmetrically with this configuration by reversing the positional relationship in the width direction of the vertical rectangular region, the seismic resistance of the building can be further improved.

The third aspect of the present invention is the seismic device of the building according to the second aspect, in which the opening faces the vertical rectangular region, and the predetermined height is higher than the opening. high.
According to this configuration, in a normal time when an earthquake exceeding a regulation does not arrive, the long member does not interfere with the opening, so that the function of the opening is not hindered.

The fourth aspect of the present invention is a seismic device for a building according to any one of the first to third aspects, wherein an opening faces the vertically rectangular region, and the opening faces the opening. A door that opens and closes the opening is provided, and by mechanically transmitting the movement of the door, when the door is not closed, the weight locking mechanism releases the locked state of the weight. It is further provided with a locking release blocking mechanism that prevents the locking.

According to this configuration, when the door is not closed, the brace is not formed even if an earthquake occurs, so that a person who goes in and out through the open door is prevented from going in and out by the formation of the brace. There is no. Since no electrical mechanism is required to prevent the formation of braces, operation is not hindered even if a power outage occurs due to an earthquake.

The fifth aspect of the present invention is a seismic device of a building that enhances the seismic resistance of the building by forming a brace in a predetermined vertical rectangular region of the building at the time of an earthquake. , A first relay mechanism, a weight, a guide member, a relay release mechanism, and a detent mechanism. One end of the string is fixed to the upper part of the vertical rectangular region on the one end side in the width direction. The first relay mechanism relays the string extending from one end of the vertical rectangular region at the upper portion on the other end side in the width direction so as to be releasable. The weight is connected to the other end of the string body which is relayed and further extended. The guide member is installed on the other end side in the width direction of the vertical rectangular region, and guides the weight so that it can fall from a predetermined height lower than the upper portion to the lower portion. The relay release mechanism has an earthquake detection weight, and mechanically transmits the movement of the earthquake detection weight due to an earthquake with a strength exceeding the specified value so as to release the relay state of the string body. The first relay mechanism is driven. The detent mechanism stops the reversion of the weight when the weight is guided by the guide member and falls and reaches the lower portion. The length of the string is set to the length at which the weight is at the lower part to form a brace when there is no earthquake.

According to this configuration, in normal times when an earthquake exceeding the regulation does not arrive, no brace is formed in the vertical rectangular region of the building, and the string is from the upper part of the widthwise end side of the vertical rectangular region to the other end side. It is arranged over the upper part, and further arranged along the other end side in the width direction to the portion connected to the weight. That is, the string is arranged in the peripheral portion of the vertical rectangular region. Therefore, when an opening such as an entrance / exit or a window faces the vertically rectangular region, the function of the opening is not hindered in normal times. When an earthquake that exceeds the regulation arrives, the movement of the earthquake detection weight accompanying the earthquake is mechanically transmitted, so that the relay state of the string body by the first relay mechanism is released, and the weight is guided by the guide member while being guided. It falls to the lower part on the other end side in the width direction of the vertical rectangular area. As a result, the string body forms a brace. The fallen weight is stopped from returning by the detent mechanism, and the length of the string is set to the original length as a brace. For this reason, the string body exerts a function as a brace formed in the vertical rectangular region, and contributes to the improvement of the earthquake resistance of the building. Since no electrical mechanism is required to form the brace, even if a power outage occurs due to an earthquake, the operation is not hindered. By further providing a seismic device configured symmetrically with this configuration by reversing the positional relationship in the width direction of the vertical rectangular region, the seismic resistance of the building can be further improved.

The sixth aspect of the present invention is a seismic device of a building that enhances the seismic resistance of the building by forming a brace in a predetermined vertical rectangular region of the building at the time of an earthquake. , A first relay mechanism, a second relay mechanism, an elastic member, a relay release mechanism, and a detent mechanism. One end of the string is fixed to the upper part of the vertical rectangular region on the one end side in the width direction. The first relay mechanism relays the string extending from one end of the vertical rectangular region so as to be releasable at the lower portion of the vertical rectangular region on the one end side in the width direction or the upper portion on the other end side. The second relay mechanism slidably relays the string body that is relayed and further extends at the lower portion on the other end side in the width direction. The elastic member is connected to the other end of the string body which is relayed by the second relay mechanism and further extends, and is urged to pull the other end. The relay release mechanism has an earthquake detection weight, and mechanically transmits the movement of the earthquake detection weight due to an earthquake with a strength exceeding the specified value so as to release the relay state of the string body. The first relay mechanism is driven. The detent mechanism prevents the string body pulled out from the second relay mechanism by the urging of the elastic member from returning to the second relay mechanism.

According to this configuration, in normal times when an earthquake exceeding the regulation does not arrive, no brace is formed in the vertical rectangular region of the building, and the string is from the upper part of the widthwise one end side to the other end side of the vertical rectangular region. It is located over the top and further along the other end of the width from the top to the bottom, or from the top to the bottom of the width end and further from the bottom of the width end to the bottom of the other end. The string further extends from the lower end on the other end in the width direction until it is connected to the elastic member. That is, the string is arranged along the peripheral portion of the vertical rectangular region. Therefore, when an opening such as an entrance / exit or a window faces the vertically rectangular region, the function of the opening is not hindered in normal times. When an earthquake that exceeds the regulation arrives, the movement of the earthquake detection weight accompanying the earthquake is mechanically transmitted, so that the relay state of the string body by the first relay mechanism is released and the string body slides on the second relay mechanism. While being pulled by the elastic member. As a result, the string body forms a brace. The string pulled out from the second relay mechanism is stopped from returning by the detent mechanism. For this reason, the string body exerts a function as a brace formed in the vertical rectangular region, and contributes to the improvement of the earthquake resistance of the building. Since no electrical mechanism is required to form the brace, even if a power outage occurs due to an earthquake, the operation is not hindered. By further providing a seismic device configured symmetrically with this configuration by reversing the positional relationship in the width direction of the vertical rectangular region, the seismic resistance of the building can be further improved.

The seventh aspect of the present invention is the seismic resistance device of the building according to the fifth or sixth aspect, in which the opening faces the vertically rectangular region, and the opening faces the opening. A door that opens and closes the portion is provided, and by mechanically transmitting the movement of the door, when the door is not closed, the relay that prevents the first relay mechanism from releasing the relay state of the string. It is further equipped with a release prevention mechanism.

According to this configuration, when the door is not closed, the brace is not formed even if an earthquake occurs, so that the person entering and exiting through the open door is not prevented from entering and exiting by the formation of the brace. Since no electrical mechanism is required to prevent the formation of braces, operation is not hindered even if a power outage occurs due to an earthquake.

As described above, according to the present invention, even if a power failure occurs due to the occurrence of an earthquake, a building seismic resistance device that forms a brace in the building at the time of an earthquake without being hindered is realized.

1 and 2 are diagrams illustrating a schematic configuration of a seismic resistance device according to the first embodiment of the present invention, FIG. 1 shows a normal state, and FIG. 2 shows a state at the time of an earthquake. There is. The seismic resistance device 211 is installed along the wall surface 2 of the building 201. An opening forming an entrance / exit is formed on the wall surface 2, and a door 1 for opening / closing this opening is provided. In the figure, in order to clearly show the structure of the seismic resistance device 211, the building 201 is shown so that the wall surface 2 faces the front. Hereinafter, terms such as "upper", "lower", "left", and "right" indicate the direction and position when the wall surface 2 on which the seismic resistance device 211 is arranged is viewed from the front.

The building 201 is, for example, a residential house, and pillars 5 and 7 are erected on the foundation 3 so as to sandwich the wall surface 2 from the left and right. Pillars 5 and 7 are, for example, through pillars that pass through the first floor and the second floor. A floor board 11 is arranged on the floor surface of the first floor. The floor board 11 is supported by the floor joists 10. A ceiling plate 12 is arranged on the ceiling surface of the first floor, and a beam 13 is arranged between the first floor and the second floor. As an example, the ceiling plate 12 is arranged at the height of the lower surface of the horizontal member 14 that guides the door 1. As an example, reinforcing members 15 and 17 are provided between the upper portions of the columns 5 and 7 and the beam 13. Here, the "upper part" of the pillars 5 and 7 means the "upper part" of the first floor portion of the pillars 5 and 7. These columns 5, 7, the floor joists 10, and the reinforcing members 15, 17 are all components of the building 201, and are used to attach each component of the seismic resistance device 211.

The seismic resistance device 211 has a long member 19, and the long member 19 has long elements 21 and 23 rotatably connected to each other. One end of the long element 21 is rotatably supported by the reinforcing material 15, and the other end is rotatably connected to one end of the long element 23. The other end of the long element 23 is rotatably connected to the weight 25. The long element 23 has a cylindrical body 27 and a rod-shaped body 29 slidably inserted into the tubular body 27, whereby the elongated element 23 can be expanded and contracted in a telescope manner. .. The cross-sectional shapes of the tubular body 27 and the rod-shaped body 29 are rectangular as an example. Further, the long element 23 has an extending portion 20 extending in the longitudinal direction beyond the connecting portion between the long element 21 and itself. As an example, the extending portion 20 is a rod-shaped member having a rectangular cross section, and the long element 21 is a member having a “U” cross section so as to receive the extending portion 20.

A long guide member 31 that slidably guides the weight 25 in the vertical direction is fixed to the pillar 7 via the spacer 22. The lower end of the guide member 31 is further screwed to the building structural material 44. The building structural material 44 is fixed to, for example, the foundation 3 or the pillars 5 and 7. As the weight 25 slides vertically along the guide member 31, the long elements 21 and 23 are placed in a plane parallel to the plane including the central axes of the columns 5 and 7, in other words, in a plane along the wall surface 2. Rotate. This plane is a kind of virtual plane and corresponds to a specific example of the vertical rectangular region of the present invention. As the long elements 21 and 23 rotate, the rod-shaped body 29 slides with respect to the tubular body 27, so that the long element 23 expands and contracts.

A weight locking mechanism 33 that releasably locks the weight 25 is attached to the pillar 7 or the reinforcing member 17. The weight locking mechanism 33 has a position where the other end of the long element 23 connected to the weight 25 is lower than one end of the long element 21 and slightly higher than the opening of the wall surface 2 opened and closed by the door 1. That is, the weight 25 is locked so as to be slightly higher than the ceiling plate 12. As shown in FIG. 1, the weight locking mechanism 33 locks the weight 25 in a normal time without an earthquake, but when an earthquake occurs, the weight locking mechanism 33 releases the locked state as shown in FIG. Drop the weight 25. The long element 23 has a length holding mechanism 24 that holds the length of the long element 23 so as to be in a horizontal posture in a normal time without an earthquake. When the weight 25 falls due to the occurrence of an earthquake, the length holding mechanism 24 releases the holding state and enables the long element 23 to be extended. A configuration example of the length holding mechanism 24 will be described later.

FIG. 3 is a perspective view illustrating the schematic configuration of the weight 25. Further, FIG. 4 is a perspective view illustrating the configuration of the mechanism for opening the passage of the weight 25. The weight 25 is slidably supported by an upright guide member 31. The other end of the long element 23 is pivotally supported by the weight 25. When the weight 25 falls, it penetrates below the floor plate 11 (that is, under the floor). Therefore, the floor plate 11 is formed with an opening that allows the weight 25 to pass through, and is further provided with a lid 26 that covers the opening so that it can be opened and closed. In the example of FIG. 4, the lid 26 opens and closes the opening by sliding in the horizontal direction. A tubular body 30 is disposed on the back (that is, below) of the floor plate 11 and the back of the wall surface 28, and a string body 32 such as a wire is inserted through the tubular body 30. One end of the string 32 is connected to the lid 26, and the other end is connected to the hook (uncinus) 34 that engages with the weight 25. The hook 34 awaits the weight 25 in a state of being suspended from the opening end 36 of the tubular body 30 to the front side of the wall surface 28 by the string body 32 to the front side of the wall surface 28. When the weight 25 falls, the hook 34 engages with the recess 50 having a "V" cross section formed on the bottom surface of the weight 25. As the weight 25 descends, the other end of the string 32 is pulled down by the hook 34, and as a result, the lid 26 to which one end of the string 32 is connected is opened. As a result, the weight 25 can pass through the opening.

Returning to FIG. 2, when the weight 25 is guided by the guide member 31 and falls and reaches under the floor, the detent mechanism 35 stops the reversion of the weight 25. The detent mechanism 35 has a locking member 37. The locking member 37 is rotatably shafted to a building structure (not shown) arranged under the floor, such as a plate-shaped member fixed to any of a pillar 7, a floor joist 10, and a building structural material 44. Be provided. The locking member 37 is formed with a hook-shaped protrusion 42 that engages with a hook-shaped retracting portion 45 (see FIG. 3) formed on the side surface of the weight 25. The locking member 37 abuts on the stopper 40 also provided on the structural member (not shown), thereby limiting the rotation range. The elastic members 39 and 41 provided on the floor joist 10 urge the locking member 37 to maintain a contact with the stopper 40. The locking member 37 waits for the weight 25 to fall while maintaining this posture. When the weight 25 falls, the protrusion 42 of the locking member 37 is pushed away by the weight 25 and further engages with the retracting portion 45 of the weight 25. This prevents the weight 25 from reversing (ie, rising again). That is, the detent mechanism 35 has a snap-fit structure. As an example, the elastic member 39 is an elastic body such as rubber, and the elastic member 41 is a compression coil spring. Only the elastic member 41 may be used without using the two types of elastic members 39 and 41.

When the weight 25 falls due to the occurrence of an earthquake and the detent mechanism 35 stops the reversion of the weight 25, the expansion / contraction prevention mechanism 43 of the long member 19 stops the expansion / contraction of the long element 23, and the length is constant. Hold the weight. At the same time, the extending portion 20 is housed in the long element 21, and their axial directions overlap each other. The long member 19 is provided with a bending restraining mechanism 47, and the bending restraining mechanism 47 causes the long element 21 and the extending portion 20 having overlapping axial directions to rotate so as not to open each other. Be stopped. As a result, the elongated elements 21 and 23 are prevented from bending each other and are held in a straight shape as illustrated in FIG. In this way, when the detent mechanism 35 stops the reversion of the weight 25, the long member 19 is stopped from expanding and contracting and bending, and behaves like a single rod. As a result, the long member 19 functions as a brace and enhances the earthquake resistance of the building 201. The length of the long member 19 when it behaves like a single rod forms a brace when the weight 25 is prevented from reversing by the detent mechanism 35 when there is no earthquake and the building 201 is not deformed. The expansion / contraction prevention mechanism 43 is set so as to have the length of the long member 19 to be used.

In the example of FIG. 2, the ascending of the weight 25 is stopped by the detent mechanism 35, and the descending of the weight 25 is not stopped. Therefore, the long member 19 exerts a drag force solely against the tensile force (tension). On the other hand, a weight support member 52 that supports the weight 25 may be arranged below the weight 25 at the position shown in FIG. 2 so as to prevent the weight 25 from descending. The weight support member 52 illustrated by the dotted line in FIG. 2 is a block-shaped member, and is fixed on, for example, a building structural member 44. The weight support member 52 may be an elastic body having high compressive strength such as rubber. When such a member is arranged, the long member 19 functions as a brace that exerts a drag force against the compressive force, so that the seismic resistance of the building 201 is further improved.

FIG. 5 is a cross-sectional view illustrating the configuration of the length holding mechanism 24 and the expansion / contraction preventing mechanism 43 of the long member 19. In this example, through holes 49 and 51 are formed in the side wall of the tubular body 27 of the long element 23, and the recess 53 and the through hole 55 are formed in the rod-shaped body 29 of the long element 23. ing. Further, on the side wall of the tubular body 27, a pin 57 capable of penetrating through holes 49 and 51 and a pin support member 59 slidably supporting the pin 57 are installed. The pin support member 59 is provided with an elastic member 61 that urges the pin 57 so as to penetrate the through holes 49 and 51. Among these components, the recess 53 exclusively constitutes the length holding mechanism 24, and the through hole 55 exclusively constitutes the expansion / contraction prevention mechanism 43. Other components constitute both the length holding mechanism 24 and the expansion / contraction preventing mechanism 43.

In normal times when there is no earthquake, the tip of the pin 57 is inserted into the recess 53 of the rod-shaped body 29, as illustrated in FIG. As a result, the rod-shaped body 29 is prevented from sliding with respect to the tubular body 27, and the length of the long element 23 is kept constant. The long element 23 illustrated in FIG. 1 is in this state. The position of the recess 53 along the axial direction is selected so that the elongated element 23 is in a horizontal position. When an earthquake occurs and the weight 25 falls, a strong force acts on the rod-shaped body 29 in the direction of the arrow in FIG. 5 so as to extend the long element 23. As a result, the engaged state between the recess 53 and the pin 57 is released, and the rod-shaped body 29 slides in the direction of the arrow while being guided by the tubular body 27. As described above, when a force of a certain amount or more is applied to the rod-shaped body 29, the engagement state between the recess 53 and the tip end portion of the pin 57 is released. When the weight 25 is locked by the detent mechanism 35, the through hole 55 of the rod-shaped body 29 overlaps with the through holes 49, 51 of the tubular body 27. As a result, the pin 57 penetrates these three through holes 49, 55, 51. As a result, the rod-shaped body 29 is pinned to the tubular body 27, and the expansion and contraction of the long element 23 is stopped. The long element 23 illustrated in FIG. 2 is in this state. Unless the pin 57 is artificially pulled out, the pinned state of the rod-shaped body 29 and the tubular body 27 is not released.

6A and 6B are views illustrating the configuration of the bending restraining mechanism 47, where FIG. 6A is a perspective view and FIG. 6B is a cross-sectional view. The illustrated bending restraining mechanism 47 has a structure similar to the expansion / contraction stopping mechanism 43 illustrated in FIG. That is, through holes 63 and 65 are formed in the side wall of the long element 21 having a "U" cross section, and through holes 67 are formed in the extending portion 20. Further, on the side wall of the long element 21, a pin 69 capable of penetrating the through holes 63 and 65 and a pin support member 71 slidably supporting the pin 69 are installed. The pin support member 71 is provided with an elastic member 73 that urges the pin 69 so as to penetrate the through holes 63 and 65. The pin support member 71 is further provided with a plate-shaped position regulating member 75 that regulates the position of the tip of the pin 69. The tip of the pin 69 penetrates the through hole 77 formed in the position restricting member 75.

A plate-shaped pin blocking member 79 that prevents the pin 69 from penetrating the through holes 63 and 65 is inserted between the position restricting member 75 and the long element 21. The pin blocking member 79 is held between the position restricting member 75 and the long element 21 without being displaced by the frictional force generated by the pressing of the tip of the pin 69. As shown in the figure, the pin blocking member 79 is installed so as to project on the side where the extending portion 20 is received. A through hole 81 through which the pin 69 can penetrate is formed in the protruding portion of the pin blocking member 79.

Behind the through hole 67 in the extending portion 20 seen from the long element 21, a plate-shaped protruding member 83 projecting from the surface of the extending portion 20 in which the through hole 67 opens is provided. As an earthquake occurs and the weight 25 falls, the extending portion 20 rotates so as to approach the long element 21, and is further welcomed into the groove 90 of the long element 21. At this time, the protruding member 83 comes into contact with the pin blocking member 79 and pushes the pin blocking member 79. Since the pin blocking member 79 is prevented from being displaced only by the frictional force generated by the pressing of the tip of the pin 69, the pin blocking member 79 retreats without being able to withstand the pressing of the protruding member 83. As a result, the through hole 81 of the pin blocking member 79 reaches the position of the tip end portion of the pin 69, so that the pin 69 penetrates the through holes 81, 63, 67, 65. As a result, the extending portion 20 is pinned to the long element 21 in a state of being accommodated in the groove 90 of the long element 21, and the bending of the long member 19 is stopped. Unless the pin 69 is artificially pulled out, the pinned state of the extending portion 20 and the long element 21 is not released.

7 and 8 are views illustrating the configuration of the weight locking mechanism 33, FIG. 7 is a perspective view, FIG. 8A is a plan sectional view, and FIG. 8B is a front view. The weight locking mechanism 33 has a pin 93 for locking the weight 25 by being inserted into a locking hole 91 formed in the side wall of the weight 25. The pin 93 is supported by the pin support member 95 so that it can be inserted and removed from the locking hole 91. The pin support member 95 is fixed to a building structural material such as a reinforcing material 17 by, for example, screwing. The pin 93 is urged by the elastic member 97 in the direction of releasing the lock. The elastic member 97 is, for example, a compression coil spring. In normal times when there is no earthquake, the pin 93 is pressed in the direction of locking the weight 25 by the pressing lever 99 rotatably supported by the pin supporting member 95. The pressing lever 99 is urged by the elastic member 101 in the direction of pressing the pin 93. The elastic member 101 is, for example, a tension coil spring. The holding lever 99 is connected to a tilting lever 105 (see FIGS. 1 and 2) that tilts when an earthquake occurs by a string body 103 such as a wire. When the tilting lever 105 is tilted, the holding lever 99 is disengaged from the pin 93, whereby the pin 93 is separated from the locking hole 91 of the weight 25 and the locked state of the weight 25 is released.

The pin 93 has a flange 109 on which the magnet 107 is arranged. Another magnet 110 is arranged on the pin support member 95 so as to face the magnet 107. The pin 93 is supported by the pin support member 95 so as to be rotatable around its axis. In normal times when there is no earthquake, the pin 93 is in a rotational position where the magnet 107 and the magnet 110 attract each other with opposite polarities (that is, attractive polarities). A rotation lever 111 for rotating the pin 93 is connected to the head of the pin 93. The rotary lever 111 is connected to the tilt lever 105 (see FIGS. 1 and 2) by a string 113 such as a wire. As described above, when the tilting lever 105 is tilted, the holding lever 99 is disengaged from the pin 93, whereby the pin 93 is separated from the locking hole 91 of the weight 25. At this time, the rotation lever 111 rotates to the rotation position where the magnet 107 and the magnet 110 have the same polarity (that is, the polarities that repel each other) and face each other. Due to the repulsive force between the magnet 107 and the magnet 110, the force for pulling out the pin 93 from the locking hole 91 of the weight 25 is increased. Therefore, even when the urging force of the elastic member 97 is insufficient, the locked state of the weight 25 can be released. When the magnet 107 and the magnet 110 are attracted to each other, a large force is required to rotate the pin 93. Therefore, when the tilting lever 105 is tilted, it is desirable to set the string body 113 looser than the string body 103 so that the holding lever 99 is removed from the pin 93 and then the pin 93 is rotated.

Returning to FIGS. 1 and 2, the tilt lever 105 is rotatably supported by a rotation shaft 114 fixed to some building structural material (not shown). This building structural material is, for example, a plate-shaped member fixed to a beam 13. When another long member 19 is juxtaposed symmetrically with the seismic resistance device 211, as shown in the figure, the tilt lever 105 has a string connected to the weight locking mechanism 33 for the other long member 19. The bodies 115 and 117 are connected. The tilting lever 105 is urged by the elastic member 119 in the direction of pulling the strings 103, 113, 115, and 117. The elastic member 119 is supported by some kind of building structural material such as a plate-shaped member fixed to the beam 13 (not shown), and is, for example, a tension coil spring. The tensile force of the elastic member 119 has sufficient strength to release the locked state of the weight 25 by the pair of weight locking mechanisms 33.

In normal times when there is no earthquake, the tilt lever 105 is restrained from tilting by the tilt restraining lever 121. The tilt restraining lever 121 is rotatably supported by some building structural material such as a plate-shaped member (not shown) fixed to the beam 13. A string body 123 such as a wire is connected to the tilt restraining lever 121. The string body 123 is extended in a direction changed by a relay member 124 supported by some building structural material such as a plate-shaped member (not shown) fixed to the beam 13, and the earthquake illustrated in FIG. 9 is exemplified. It is connected to the detection weight 125. The seismic detection weight 125 is held by a weight holding member 127 supported by a building structural material such as a pillar 7. The weight holding member 127 has an annular member 129 as an example, and an earthquake detection weight 125 is placed on the annular member 129.

When an earthquake of a predetermined strength or higher occurs, the earthquake detection weight 125 falls from the weight holding member 127. As a result, the gravity of the seismic detection weight 125 or the impact caused by the fall is transmitted to the tilt control lever 121 through the string body 123. Due to this gravity or impact, the tilt restraining lever 121 releases the restraining state of the tilt lever 105 as illustrated in FIG. As a result, tension is applied to the strings 103, 113, 115, and 117 by the tensile force of the elastic member 119, and the locked state of the weight 25 by the weight locking mechanism 33 is released. The weight holding member 127, the earthquake detection weight 125, and the transmission mechanism from the string 123 to the string 103, 113, 115, 117 that mechanically transmit the movement of the earthquake detection weight 125 are the locking of the present invention. A specific example of the release mechanism is configured.

As illustrated in FIGS. 1 and 2, the door 1 is a sliding door, and the rail that guides the door 1 is slightly tilted so that the door 1 remains in the illustrated closed state. Is desirable. Above the ceiling plate 12 (that is, behind the ceiling), in addition to the transmission mechanism such as the tilt lever 105, when the door 1 is not closed, the weight locking mechanism 33 prevents the weight 25 from being released from the locked state. A release prevention mechanism 130 is installed. The locking release prevention mechanism 130 has, for example, a tilt prevention lever 132 that prevents the tilt lever 105 from tilting. The tilt prevention lever 132 is rotatably supported by the rotation shaft 131. The rotating shaft 131 is fixed to some building structural material such as a plate-shaped member (not shown) fixed to the horizontal member 14. The tilt prevention lever 132 is set so that the weight and length of one of the rotation shaft 131 is larger than that of the other, thereby urging the rotation shaft 131 so as to tilt in the clockwise direction in the front view. Has been done. The door 1 is provided with a pressing member 133 that projects upward from the upper end thereof and presses the upper surface of the tilt preventing lever 132. The pressing member 133 is provided with a rolling element 135 such as a roller that rolls on the upper surface of the tilt preventing lever 132.

When the door 1 is opened and closed, the holding member 133 translates with the door 1. The upper surface of the tilt blocking lever 132 forms a kind of cam surface, and is formed with irregularities. As a result, when the door 1 is closed, the tilt preventing lever 132 is pressed by the pressing member 133 so as to tilt in the counterclockwise direction in the front view against the urging force. At this time, the end portion of the tilt blocking lever 132 close to the tilt lever 105 retracts downward so as not to interfere with the tilt lever 105. 1 and 2 show the tilt prevention lever 132 in this state with a solid line.

On the other hand, when the door 1 is opened, the rolling element 135 of the pressing member 133 is located at the retracted portion formed on the upper surface of the tilt preventing lever 132. FIG. 1 illustrates the position of the holding member 133 when the door 1 is opened by a dotted line. As a result, the tilt prevention lever 132 tilts in the clockwise direction in the front view according to the urging force. At this time, the end portion of the tilt prevention lever 132 close to the tilt lever 105 is lifted so as to prevent the tilt lever 105 from tilting. In FIG. 1, the tilt prevention lever 132 in this state is represented by a dotted line. Therefore, when the door 1 is not closed, an earthquake occurs and the gravity or impact of the seismic detection weight 125 is transmitted to the tilt control lever 121, and even if the tilt lever 105 tries to tilt, the end of the tilt prevention lever 132. The part prevents tilting. Therefore, the weight 25 does not fall and the long member 19 does not form a brace.

From the above, it is understood that the seismic resistance device 211 has the following advantages. All operations from earthquake detection to brace formation are mechanically realized and do not require an electrical mechanism, so even if a power outage occurs due to an earthquake, the operation will not be hindered. Further, in a normal time when an earthquake exceeding a regulation does not arrive, the long member 19 does not interfere with the doorway, so that the function of the doorway is not hindered. Further, in a normal state, the long element 23 is in a horizontal posture at a position slightly higher than the ceiling plate 12. Therefore, it is possible to prevent the pipes and the like, which are often arranged behind the ceiling, from interfering with the long member 19. Further, when the door 1 is not closed, the brace is not formed even if an earthquake occurs, so that the person entering and exiting through the opened door 1 is not hindered by the formation of the brace.

10 and 11 are diagrams illustrating a schematic configuration of a seismic resistance device according to a second embodiment of the present invention, FIG. 10 shows a normal state, and FIG. 11 shows a state at the time of an earthquake. There is. The seismic resistance device 212 is different from the seismic resistance device 211 illustrated in FIGS. 1 to 9 in that a long member 137 is used instead of the long member 19. One end of the long member 137 is rotatably supported by the reinforcing member 15, and the other end is rotatably connected to the weight 25. The long member 137 has a cylindrical body 139 and a rod-shaped body 141 slidably inserted into the tubular body 139, whereby the elongated member 137 can be expanded and contracted in a telescope manner. There is. In the illustrated example, the end of the tubular body 139 is supported by the reinforcing member 15, and the end of the rod-shaped body 141 is connected to the weight 25. The cross-sectional shapes of the tubular body 139 and the rod-shaped body 141 are rectangular as an example. The weight locking mechanism 33 locks the weight 25 at a height at which the long member 137 becomes horizontal in a normal time when there is no earthquake. When the weight 25 falls due to the occurrence of an earthquake, the long member 137 rotates around one end while stretching.

The elongated member 137 has a simpler structure than the bendable elongated member 19 (see FIGS. 1 and 2). The long member 137 has an expansion / contraction prevention mechanism 143 like the long element 23 of the long member 19. As an example, the structure is the same as the expansion / contraction prevention mechanism 43 illustrated in FIG. When the weight 25 falls due to the occurrence of an earthquake and the detent mechanism 35 prevents the weight 25 from returning, the long member 137 is stopped from expanding and contracting by the expansion and contraction prevention mechanism 143 of the long member 137, and is constant. Keep the length. As a result, the long member 137 functions as a brace and enhances the seismic resistance of the building 201. The length of the long member 137 when the expansion and contraction is stopped and behaves like a single rod is when the weight 25 is stopped from returning by the detent mechanism 35 when there is no earthquake and the building 201 is not deformed. In addition, the expansion / contraction prevention mechanism 143 is set so as to have the length of the long member 137 forming the brace. As illustrated in FIG. 2, a weight support member 52 that prevents the weight 25 from descending may be arranged.

12 and 13 are diagrams illustrating a schematic configuration of a seismic resistance device according to a third embodiment of the present invention, FIG. 12 shows a normal state, and FIG. 13 shows a state at the time of an earthquake. There is. The seismic devices 213 are seismic devices exemplified in FIGS. 1 to 11 in that a string body 145 such as a wire is used instead of the rigid long members 19 and 137 as the members forming the brace. It is different from 211 and 212. One end of the string body 145 is fixed to the reinforcing material 15, and the other end is connected to the weight 25. A relay mechanism 147 that relays the string body 145 so that it can be released is attached to the reinforcing material 17. As a result, the weight 25 is held in a state of being suspended by the string body 145. In normal times when there is no earthquake, the string body 145 extends substantially horizontally in the section from one end stopped by the reinforcing material 15 to being relayed by the relay mechanism 147.

14 and 15 are views illustrating the configuration of the relay mechanism 147, FIG. 14 is a perspective view, and FIG. 15 is a plan sectional view. The relay mechanism 147 has a structure similar to that of the weight locking mechanism 33 (see FIGS. 7 and 8), and the point that the pin 151 stops the string body 145 instead of locking the weight 25 is the weight engagement. It is different from the stop mechanism 33. The pin 151 is supported by the pin support member 155 so that it can be inserted and removed from the string chamber 153 through which the string 145 is passed. The pin support member 155 is fixed to a building structural material such as a reinforcing material 17 by, for example, screwing. The pin 151 is urged by the elastic member 97 in the direction of releasing the lock. In normal times when there is no earthquake, the pin 151 is pressed in the direction of being inserted into the string chamber 153 by the pressing lever 99 rotatably supported by the pin supporting member 155. The holding lever 99 is connected to a tilting lever 105 (see FIGS. 12 and 13) that tilts when an earthquake occurs by a string body 103.

The pin 151 is supported by the pin support member 155 so as to be rotatable around its axis. A rotation lever 111 for rotating the pin 151 is connected to the head of the pin 151. The rotary lever 111 is connected to the tilt lever 105 (see FIGS. 12 and 13) by a string 113 such as a wire. When the tilting lever 105 is tilted, the holding lever 99 is disengaged from the pin 151, whereby the pin 151 is separated from the string chamber 153. At this time, the rotation lever 111 rotates to the rotation position where the magnet 107 and the magnet 110 have the same polarity (that is, the polarities that repel each other) and face each other. Due to the repulsive force between the magnet 107 and the magnet 110, the force for pulling out the pin 151 from the string chamber 153 is increased.

Returning to FIG. 13, when the tilt lever 105 is tilted due to the occurrence of an earthquake and the relay state of the string body 145 by the relay mechanism 147 is released, the weight 25 falls while being guided by the guide member 31. When the weight 25 reaches the underfloor, the detent mechanism 35 stops the reversion of the weight 25. As a result, the string body 145 functions as a brace and enhances the earthquake resistance of the building 201. The length of the string body 145 is set to a length that forms a brace when the weight 25 is prevented from reversing by the detent mechanism 35 when there is no earthquake and the building 201 is not deformed. As illustrated in FIG. 2, a weight support member 52 that prevents the weight 25 from descending may be arranged. In addition, in FIGS. 12 and 13, the portion corresponding to the unlocking mechanism of FIGS. 1 and 2 corresponds to a specific example of the relay releasing mechanism of the present invention. Similarly, the portion corresponding to the lock release prevention mechanism corresponds to a specific example of the relay release prevention mechanism of the present invention.

16 and 17 are diagrams illustrating a schematic configuration of a seismic resistance device according to a fourth embodiment of the present invention, FIG. 16 shows a normal state, and FIG. 17 shows a state at the time of an earthquake. There is. In this seismic device 214, the seismic device 213 exemplified in FIGS. 12 and 13 is in that the weight 25 is not used and the other end of the string body 145, which is a member forming the brace, is connected to the elastic member 157. Is different. The elastic member 157 is arranged below the floor plate 11, that is, under the floor, and one end thereof is fixed to the building structural material 159 installed under the floor. The elastic member 157 is, for example, a tension coil spring. Tension is applied to the string body 145 by the elastic member 157.

The tensioned string body 145 extends horizontally from one end stopped by the reinforcing material 15 to the relay mechanism 147, extends downward from the relay mechanism 147, and further extends in the extending direction under the floor by another relay mechanism 161. Is turned horizontally. The relay mechanism 161 is attached to another building structural material 162 installed under the floor. The building structural materials 159 and 162 are, for example, plate-shaped members fixed to columns 5, 7, floor joists, and the like. As an example, the relay mechanism 161 has a rotation shaft fixed to the building structural material 162 and a roller rotatably supported by the rotation shaft.

The string body 145 extending horizontally from the relay mechanism 161 passes through the detent mechanism 163 and is connected to the elastic member 157. The detent mechanism 163 prevents the string body 145 attracted by the elastic member 157 from reversing. As the detent mechanism 163, a conventionally known device that prevents the string such as a rope or a wire from reversing can be used.

As illustrated in FIG. 17, when the tilt lever 105 is tilted due to the occurrence of an earthquake and the relay state of the string body 145 by the relay mechanism 147 is released, the string body 145 is instantly moved by the tensile force of the elastic member 157. Gravitate. As a result, the string body 145 forms a brace. The drawn string 145 functions as a brace that enhances the earthquake resistance of the building 201 because the detent mechanism 163 prevents the string from reversing.

18 and 19 are diagrams illustrating a schematic configuration of a seismic resistance device according to a fifth embodiment of the present invention, FIG. 18 shows a normal state, and FIG. 19 shows a state at the time of an earthquake. There is. In this seismic resistance device 215, the relay mechanism 147 is fixed to the building structural material 159, and along with this, the relay release mechanism such as the tilt lever 105 and the relay release prevention mechanism such as the tilt prevention lever 165 are arranged under the floor. This is different from the seismic resistance device 214 (see FIGS. 16 and 17). The tilt control lever 167 that stops the tilt of the tilt lever 105 during normal times without an earthquake extends long on the opposite side of the rotation axis from the side close to the tilt lever 105, thereby stopping the tilt of the tilt lever 105. Being urged to a moving position. The tilt lever 105 and the tilt restraint lever 167 are rotatably supported by some building structural material (not shown). This building structural material is, for example, a plate-shaped member fixed to the floor joist 10.

As illustrated in FIG. 19, when the tilt lever 105 is tilted due to the occurrence of an earthquake and the relay state of the string body 145 by the relay mechanism 147 is released, the string body 145 is instantly moved by the tensile force of the elastic member 157. Gravitate. As a result, the string body 145 forms a brace. The drawn string 145 functions as a brace that enhances the earthquake resistance of the building 201 because the detent mechanism 163 prevents the string from reversing.

The tilt prevention lever 165 that prevents the tilt lever 105 from tilting when the door 1 is not closed is rotatably supported by the building structural material 159. As a result, it is urged to tilt in the counterclockwise direction in the front view in the figure. The door 1 is provided with a pressing member 171 that projects downward from the lower end thereof and presses the lower surface of the tilt preventing lever 165. The pressing member 171 is provided with a rolling element 173 such as a roller that rolls on the lower surface of the tilt preventing lever 165.

When the door 1 is opened and closed, the holding member 171 translates together with the door 1. The lower surface of the tilt blocking lever 165 is a kind of cam surface, and is formed with irregularities. As a result, when the door 1 is closed, the lower surface of the tilt preventing lever 165 is pushed up by the pressing member 171 so as to tilt in the clockwise direction in the front view against the urging force. At this time, the end portion of the tilt prevention lever 165 close to the tilt lever 105 retracts upward so as not to interfere with the tilt lever 105. 18 and 19 show the tilt prevention lever 165 in this state with a solid line.

On the other hand, when the door 1 is opened, the rolling element 173 of the pressing member 171 is located at the retracted portion formed on the lower surface of the tilt preventing lever 165. FIG. 18 illustrates the position of the pressing member 171 when the door 1 is opened by a dotted line. As a result, the tilt prevention lever 165 tilts in the counterclockwise direction in the front view according to the urging force. At this time, the end portion of the tilt prevention lever 165 close to the tilt lever 105 descends so as to prevent the tilt lever 105 from tilting. In FIG. 18, the tilt prevention lever 165 in this state is represented by a dotted line. Therefore, when the door 1 is not closed, an earthquake occurs and the gravity or impact of the seismic detection weight 125 is transmitted to the tilt control lever 167, and even if the tilt lever 105 tries to tilt, the end of the tilt prevention lever 165. The part prevents tilting. Therefore, the relay of the string body 145 by the relay mechanism 147 is not released, and the string body 145 does not form a brace.

20 and 21 are diagrams illustrating a schematic configuration of a part of the seismic resistance device according to the sixth embodiment of the present invention, FIG. 20 shows a normal state, and FIG. 21 shows a state at the time of an earthquake. Is shown. The seismic resistance device 216 further has a string body 123A branched from the string body 123 in the seismic resistance device 211 shown in FIGS. 1 and 2 as an example. One end of the string 123A is connected to the middle portion of the string 123, and the other end is connected to the tilt lever 105.

When an earthquake of a predetermined strength or higher occurs, the impact of gravity or drop of the earthquake detection weight 125 (see FIG. 9) is transmitted to the tilt restraining lever 121 through the string body 123. Due to this gravity or impact, the tilt restraining lever 121 releases the restraining state of the tilt lever 105. As a result, the tilting lever 105 is tilted as illustrated in FIG. 21 by the tensile force of the elastic member 119, and tension is applied to the strings 103, 113, 115, and 117. At this time, the string body 123A branched from the string body 123 cooperates with the elastic member 119 to tilt the tilt lever 105. Even if the elastic member 119 has a sufficient elastic restoring force to tilt the tilting lever 105, the provision of the string body 123A enhances the certainty of the tilting of the tilting lever 105. Considering that the life of the building 201 is as long as several decades, it is meaningful to provide a double mechanism for tilting the tilt lever 105.

The impact of the earthquake detection weight 125 is transmitted to the tilt restraining lever 121 through the string body 123, and after the tilt restraining lever 121 releases the restrained state of the tilting lever 105, the tension of the string body 123A is transmitted to the tilting lever 105. Is desirable. For this reason, as illustrated in FIG. 20, it is desirable to set the string 123A somewhat looser than the string 123 connected to the tilt restraining lever 121 in the normal state before the occurrence of an earthquake. The string 123A branched from the string 123 can be similarly provided not only in the illustrated seismic device 211 but also in other seismic devices 212 to 215.

FIG. 22 is a diagram illustrating a part of the schematic configuration of the seismic resistance device according to the seventh embodiment of the present invention, and shows a state in a normal state. Further, FIG. 23 is a cross-sectional view showing the structure of the door and the guide rail of FIG. 22. The seismic resistance device 217 has a structure in which the tilt prevention lever 132 is replaced with the tilt prevention lever 177 in the seismic resistance devices 211 to 214. In FIGS. 22 and 23, the members having the same functions as the members of FIGS. 1 to 21 are designated by the same reference numerals. The detailed description of the members with the same reference numerals will be omitted.

The door 1 has a rolling element 179 such as a roller at the upper end thereof, and the rolling element 179 rolls on the guide rail 181 so that the door 1 is smoothly guided to the guide rail 181. The guide rail 181 is provided, for example, as a part of the horizontal member 14 (see FIG. 1 and the like). The guide rail 181 is preferably slightly tilted so that the door 1 can be manually opened without resistance, while automatically closing when the man leaves. A magnet 183 is attached to one end of the guide rail 181 and a magnet 185 is attached to a portion of the door 1 facing the magnet 183. These magnets 183 and 185 are installed so that the same poles, for example, the N poles face each other. As a result, the door 1 is urged in the closing direction when it is opened, so that it moves in the closing direction with momentum after the human hands are separated.

The tilting lever 105 is rotatably supported by a rotating shaft 114 fixed to some building structural material (not shown). In normal times when there is no earthquake, the tilt lever 105 is restrained from tilting by the tilt restraining lever 121. In FIG. 22, the tilting lever 105 in the normal posture is represented by a solid line. When an earthquake of a predetermined strength or higher occurs, the impact of gravity or drop of the earthquake detection weight 125 (see FIG. 9) is transmitted to the tilt restraining lever 121 through the string body 123. Due to this gravity or impact, the tilt restraining lever 121 releases the restraining state of the tilt lever 105. As a result, the tilting lever 105 is tilted by the tensile force of the elastic member 119 as illustrated by the dotted line, and tension is applied to the strings 103, 113, 115, and 117. The string body 123A branched from the string body 123 assists the function of the elastic member 119 that tilts the tilting lever 105, similarly to the seismic resistance device 216 illustrated in FIGS. 20 and 21. As a result, for example, the locked state of the weight 25 by the weight locking mechanism 33 (see FIG. 1) is released, and for example, the long member 19 (see FIG. 1) forms a brace.

Like the tilt prevention lever 132 (see FIG. 1), the tilt prevention lever 177 is a member for preventing the formation of brace even if an earthquake occurs when the door 1 is not closed. As an example, the tilt prevention lever 177 has a shape that is bent in a substantially “he” shape in a plan view, and is rotatably supported by a rotation shaft 191 at the bent portion. The rotation shaft 191 is fixed to, for example, a guide rail 181. The tilt prevention lever 177 is set so that the weight and length of one of the rotation shafts 191 are larger than those of the other, so that the tilt prevention lever 177 is urged to tilt in the clockwise direction in the front view in the drawing. ing. The door 1 is provided with a pressing member 193 that projects diagonally upward from the upper end and the side end thereof and presses the lower surface of the tilt preventing lever 177. The pressing member 193 is provided with a rolling element 195 such as a roller that rolls on the lower surface of the tilt preventing lever 177.

When the door 1 is closed, the lower surface of the tilt preventing lever 177 is pressed by the pressing member 193 so as to tilt in the counterclockwise direction in the front view against the urging force. At this time, the lower end of the tilt prevention lever 177 close to the tilt lever 105 retracts downward so as not to interfere with the tilt lever 105. In FIG. 22, the tilt prevention lever 177 in this state is represented by a solid line.

On the other hand, when the door 1 is opened, the pressing member 193 translates so as to move away from the rotation shaft 191 of the tilt prevention lever 177. As a result, the tilt prevention lever 177 tilts in the clockwise direction in the front view while the lower surface thereof is supported by the rolling element 195 of the pressing member 193. When the door 1 is opened to some extent or more, the restraining member 197 provided on the tilt blocking lever 177 and the restraining member 199 provided on the guide rail 181 for example come into contact with each other, so that the tilting of the tilt blocking lever 177 is stopped. , A constant tilting posture is maintained. At this time, the lower end portion of the tilt prevention lever 177 close to the tilt lever 105 is lifted so as to prevent the tilt lever 105 from tilting. In FIG. 22, the tilt prevention lever 177 in this state is represented by a dotted line. Therefore, when the door 1 is not closed, an earthquake occurs and the gravity or impact of the earthquake detection weight 125 is transmitted to the tilt control lever 121 through the string body 123, and even if the tilt lever 105 tries to tilt, the tilt is prevented. The lower end of the lever 177 prevents tilting. Therefore, no brace is formed.
