  For example, in Patent Documents 1 to 3, a moving member made of an arm, a rod or the like that abuts at a predetermined angle against a shoji that moves slowly in the closing direction of the opening of the building is rotated against its own weight, There has been proposed a shock absorber for a window opening / closing device in which the moving member that comes into contact with the shoji that moves at a high speed in the closing direction with a predetermined angle is directly moved against an urging force such as a coil spring.

  By the way, in such a shock absorber for a window opening / closing device, it is necessary to accurately set a predetermined angle at which the shoji and the moving member abut in order to rotate and move the moving member in accordance with the movement of the shoji in the closing direction. However, since there is a minute gap in each movable part of the window opening and closing device, there is a possibility that an error occurs in the predetermined angle and a desired buffering operation cannot be performed. Further, in such a shock absorber for the window opening / closing device, it is necessary to accurately install the moving member so as to abut against the shoji at the predetermined angle. In addition, it is difficult to install it quickly.

And a connecting mechanism 19 that is connected to the window frame 3 so as to be openable and closable in the A direction. Since the connecting means 8 is provided on each of one side and the other side of the pair of vertical frames 14, and each of the pair of connecting means 8 is formed in the same manner, hereinafter, the one vertical frame The connecting means 8 on the 14 side will be described in detail, and the detailed description of the connecting means 8 on the other side of the vertical frame 14 will be omitted.

  The connecting mechanism 18 is attached to the part 6 on the upper collar 22 side of the vertical rod 24 and is attached to the shaft body 31 that moves up and down relative to the vertical frame 14 and the vertical frame 14 and the vertical frame 14 of the shaft body 31. And a guide member 32 for guiding the ascending and descending.

  The shaft body 31 is fitted to the guide member 32 so as to be rotatable and movable up and down. The shaft body 31 may be provided with a rolling roller for being smoothly guided by the guide member 32.

  The guide member 32 is fixed to the vertical frame 14. In this example, the guide member 32 is connected to the guide path 43 for guiding the part 6 in the vertical direction V, and the lower end is connected to the upper end of the guide path 43, the lower end is on the outside 9 side of the building, and the upper end is in the building 10. And a guide path 44 that guides in an inclined direction inclined with respect to the guide path 43 so as to be disposed on the side. The shaft body 31 mounted on the part 6 is arranged to be movable in the vertical direction V in the guide path 43 and to be movable in the tilt direction in the guide path 44. The guide paths 43 and 44 guide the part 6 of the shoji 5 along the guide paths 43 and 44 through the shaft body 31.

  The connecting mechanism 18 moves the shaft body 31 located in the region 6 upward or downward with respect to the window frame 3 in order to adjust the moving force toward the opening opening position of the shoji 5 or the moving force toward the opening closing position. And an urging member (not shown) made of a coil spring or the like that urges elastically.

  The connection mechanism 19 is connected to the part 7 of the shoji 5 so as to be rotatable about the rotation axis C1 and is connected to the part 35 of the window frame 3 positioned below the part 7 with respect to the vertical direction V. A pivoting arm 36 as a pivoting member that pivots in the R1 and R2 directions based on the opening / closing movement of the shoji 5 in the A direction, and the shoji 5 and the window frame 3 On the other hand, in this example, it is provided in the vertical frame 14 of the window frame 3 and swings with respect to one of the shoji 5 and the window frame 3 as the rotating arm 36 rotates in the R1 and R2 directions. A guide path 37 that guides the linear motion in the vertical direction V with respect to the frame 3 and a portion 39 of the rotating arm 36 located between the rotation axes C1 and C2 are rotatably connected around the rotation axis C3. , With respect to the part 39 with respect to the vertical direction V In other words, it is connected to the portion 40 of the window frame 3 located on the upper side with respect to the portion 39 with respect to the vertical direction V on the rotation axis C1 side so as to be rotatable about the rotation axis C4. And a connecting arm 38 as a connecting member that rotates based on the rotation of 36 in the R1 and R2 directions. The parts 35 and 40 are arranged in the vertical frame 14.

  The pivot arm 36 is connected to the part 7 of the vertical shaft 24 at the end of the shoji 5 so as to be rotatable about a rotation axis C1 as a horizontal axis extending in the lateral direction Y, and on the window frame 3 side. Is connected to the vertical frame 14 via a guide path 37 so as to be rotatable about a rotation axis C2 as a horizontal axis extending in the horizontal direction Y. The rotation axis C2 is located below the rotation axis C1.

  The connecting arm 38 is rotatably connected around the rotation axis C3 at the end on the rotating arm 36 side, and is connected rotatably around the rotation axis C4 at the end on the window frame 3 side. Has been. The rotation axis C4 is located above the rotation axis C2.

  The guide path 37 is a long hole or slit formed in the vertical frame 14 extending in the vertical direction V, and is formed in the plate-like body 15 fixed to the lower portion of the main body 17 extending in the vertical direction V of the vertical frame 14. ing. In the guide path 37, a shaft body 41 attached to the end of the rotating arm 36 on the window frame 3 side is disposed so as to be rotatable about the rotation axis C2. The shaft body 41 is fitted to the guide path 37 so as to be linearly movable in the vertical direction V. The shaft body 41 may be provided with a rolling roller for being smoothly guided by the guide path 37. The guide path 37 linearly guides the shaft body 41 on a line extending in the vertical direction V passing through the rotation axes C2 and C4.

  In addition, when the shaft body 41 reaches the upper end of the guide path 37, the rotation arm 36 is prohibited from rotating in the R1 direction, and thus the opening movement of the shoji 5 that opens the opening 4 in the A direction is also prohibited. In addition, when the shaft body 41 reaches the lower end of the guide path 37, the rotation arm 36 is prohibited from rotating in the R2 direction. Closed movements at may also be prohibited.

  In this example, the ratio of the length L1 from the rotation axis C3 to the rotation axis C4 and the length L2 from the rotation axis C2 to the rotation axis C3 is the length L2 and the rotation axis C1 to the rotation axis. It is equal to the ratio with the length L3 to the center C3. The rotating arm 36 and the connecting arm 38 are formed so that the lengths from L1 to L3 have a relationship of “L1: L2 = L2: L3”, respectively.

  The connecting means 8 can cause the portion 7 to perform a so-called approximate parallel motion (Scott Russell's parallel motion) in the inside-outside direction X of the building as the shoji 5 opens and closes the opening 4 and has a length L2. When L3 and L3 are equal to each other, the opening 7 is opened and closed by the shoji 5 so that the portion 7 can perform a so-called strict linear motion in the inside-outside direction X of the building, and the rotation axis C1 passes through the rotation axes C1 and C4. A strictly linear motion can be performed on a line extending in the inward / outward direction X. The lengths L1 to L3 may be equal to each other. Note that the inside / outside direction X of the building is a direction parallel to the horizontal direction and orthogonal to the horizontal direction Y in this example.

  For example, as shown in FIGS. 2 to 7, the shock absorber 1 is moved by the addition of a moving force based on the opening / closing movement of the shoji 5 in the A direction, and in this example, is rotated as a moving member that rotates and moves in the r1 and r2 directions. The arm 51 and the window frame 3 or the shoji 5 can be moved freely. In this example, the vertical frame 14 is rotatably mounted in the r1 and r2 directions and can be moved to the rotationally movable arm 51. In this example, the rotationally movable arm. The disc-shaped rotationally movable plate 52 as a movable member that is rotatably coupled in the same direction as the directions r1 and r2 in which the component 51 rotates, and the rotationally movable plate 52 with respect to the window frame 3 in the direction r1. The anti-movement force applying means 53 for applying the anti-movement force D1 against the rotation movement to the rotation movable plate 52 based on the rotation movement, and the rotational movement of the rotation movement plate 52 with respect to the rotation movement arm 51 in the r2 direction. Based on the anti-movement force applying means 54 for applying the anti-movement force D2 against the rotation movement to the rotation movable plate 52 based on the rotation movement of the rotation movement arm 51 in the r1 direction, the window frame 3 and the rotation movement One of the arms 51, in this example, a movement prohibiting means 55 for prohibiting the rotational movement of the rotatable movable plate 52 in the r1 direction relative to the vertical frame 14 and a later-described locked member 86 are provided in the r1 direction of the rotational moving arm 51. An elastic biasing member 56 that elastically biases the locked member 86 in the r4 direction opposite to the r3 direction that swings based on the rotational movement, and the window frame 3 or the shoji 5, in this example, the vertical frame 14 and a mounting plate 58 having a shaft body 57 on which a rotationally movable arm 51 and a rotationally movable plate 52 are rotatably mounted.

  For example, as shown in FIGS. 3 and 4, the rotary moving arm 51 includes an arm body 61, a circular hole 62 that is formed at one end of the arm body 61 and through which the shaft body 57 is inserted, and an arm body. A rolling roller 63 is provided as a contact portion that is rotatably provided at the other end of 61 and is in contact with the shoji 5. A bearing is interposed between the circular hole 62 and the shaft body 57. The rotational movement arm 51 is attached to the mounting plate 58 so as to be rotatable in the directions r1 and r2 about the axis O of the shaft body 57 by inserting the shaft body 57 into the circular hole 62.

  The arm main body 61 is arranged so as to generate a rotational movement in the r1 direction when the rolling roller 63 is pressed toward the inside 10 of the building in the inside / outside direction X of the building by the shoji 5 that has closed movement in the A direction. Has been.

  In this example, the rolling roller 63 is in contact with the surface of the vertical shaft 24 on the side of the building 10 and moves along the surface of the vertical shaft 24 while rotating in the rotational movement of the arm body 61 in the r1 and r2 directions. It is arranged to do.

  As shown in FIG. 8, the rotational movement arm 51 is disposed so as to abut against the regulation pin 65 erected on the mounting plate 58 at the maximum rotational movement position in the r2 direction. By the contact, the rotational movement in the r2 direction exceeding the maximum rotational movement position in the r2 direction is restricted. For example, when the rotational movement arm 51 is arranged at the maximum rotational movement position in the r2 direction, the regulation pin 65 is engaged with the rotationally movable plate 52 with respect to the mounting plate 58, and the rotational movement is caused by this engagement. When the rotational movement in the r2 direction exceeding the maximum rotational movement position in the r2 direction of the arm 51 is restricted, the restriction pin 65 may be omitted.

  For example, as shown in FIGS. 3 to 5, the rotationally movable plate 52 is provided at a central portion of the disk-shaped main body 71 and a disk-shaped main body 71 interposed between the mounting plate 58 and the rotationally-moving arm 51. And a circular hole 72 inserted through the shaft body 57. A bearing is interposed between the circular hole 72 and the shaft body 57. The rotatable plate 52 is attached to a mounting plate 58 by inserting a shaft body 57 through the circular hole 72 so as to be rotatable in the r1 and r2 directions. The rotationally movable plate 52 is attached to the vertical frame 14 via a mounting plate 58, and is rotatable in the r1 and r2 directions with respect to the vertical frame 14, and is relatively r1 with respect to the rotationally movable arm 51. And can be rotated in the r2 direction. As long as the anti-movement force D1 does not exceed the anti-movement force D2, the rotationally movable plate 52 transmits the rotational movement of the rotary movement arm 51 in the r1 direction via the anti-movement force applying means 54, thereby rotating the rotation movement arm. 51 is rotated in the same direction as the r1 direction which is the rotational movement direction of 51.

  In order to prevent mutual displacement of the rotationally movable arm 51 and the rotationally movable plate 52 in the lateral direction Y, the diameter of the portion where the rotationally movable arm 51 of the shaft body 57 having a circular cross section is mounted is the diameter of the shaft body 57. It differs with respect to the diameter of the part to which the rotationally movable plate 52 is mounted. The rotationally movable arm 51 and the rotationally movable plate 52 are rotatably attached to the shaft body 57 so as to rotationally move in the r1 and r2 directions around the same axis O.

  For example, as shown in FIGS. 3 to 5 and 8, the anti-movement force applying means 53 generates an anti-movement force D 1 that gradually increases based on the rotational movement of the rotatable plate 52 relative to the window frame 3 in the r1 direction. One end is connected to the window frame 3 via a connecting pin 76 erected on the mounting plate 58 and the other end is connected to the rotationally movable plate 52 via a connecting pin 77 erected on the rotatable plate 52. Is provided with a coil spring 75 as an elastic member. The connecting pin 77 is disposed so as to be separated from the connecting pin 76 as shown in FIG. 3 by the rotational movement of the rotatable movable plate 52 in the r1 direction with respect to the window frame 3.

  The anti-movement force applying means 53 is provided when the connecting pin 77 is separated from the connecting pin 76 by the rotational movement of the rotatable movable plate 52 in the r1 direction with respect to the window frame 3 and the coil spring 75 is extended as shown in FIG. Based on the elastic restoring force in the contraction direction of the coil spring 75 generated, the rotationally movable plate 52 generates an elastic anti-movement force D1 in the r2 direction that resists the moving force in the r1 direction of the rotationally movable plate 52. Thus, the anti-movement force D1 is applied to the rotatable movable plate 52. The anti-movement force D1 by the anti-movement force applying means 53 gradually increases as the rotational movement amount of the rotatable movable plate 52 in the r1 direction with respect to the window frame 3 gradually increases, and gradually decreases as the rotational movement amount decreases. It is supposed to be.

  For example, as shown in FIGS. 3, 4, 8, and 12, the anti-movement force applying means 54 gradually increases based on the rotational movement in the r <b> 2 direction of the rotary movable plate 52 relative to the rotary movement arm 51. One end is locked to the arm body 61 and the other end is locked to the rotationally movable plate 52 via a locking pin 81 erected on the rotationally movable plate 52 so as to generate the moving force D2. And a torsion spring 82 as an elastic member. As shown in FIG. 12, the locking pin 81 is attached to a portion 83 of the arm main body 61 that locks one end of the torsion spring 82 by the rotational movement of the rotationally movable plate 52 in the r2 direction relative to the rotational movement arm 51. It arrange | positions so that it may approach.

  In the anti-movement force applying means 54, the locking pin 81 approaches the portion 83 and the torsion spring 82 is compressed as shown in FIG. 12 by the rotational movement in the r2 direction relative to the rotational movement arm 51 of the rotationally movable plate 52. On the basis of the elastic restoring force of the torsion spring 82 generated in this case, the elastically movable force D2 in the r1 direction resists the rotationally movable plate 52 against the moving force in the r2 direction of the rotatable movable plate 52. Thus, the anti-movement force D2 is applied to the rotary movable plate 52. The anti-movement force D2 by the anti-movement force applying means 54 is a rotational movement amount in the r2 direction relative to the rotation movement arm 51 of the rotation movement plate 52, in other words, the rotation movement plate 52 of the rotation movement arm 51. Is gradually increased in accordance with the gradual increase in the rotational movement amount in the r1 direction relative to the, and gradually decreases in accordance with the gradual decrease in the rotational movement amount.

  In the anti-movement force applying means 53, when the rotational movement amount of the rotationally movable plate 52 in the r1 direction with respect to the window frame 3 and the rotational movement amount of the rotationally movable arm 51 relative to the rotationally movable plate 52 are equal to each other. In other words, the anti-movement force D1 smaller than the anti-movement force D2 by the anti-movement force applying means 54 is applied to the rotary movable plate 52. In this example, the anti-movement force applying means 54 is formed so as to apply an anti-movement force D2 much larger than the anti-movement force D1 by the anti-movement force applying means 53 to the rotary movable plate 52, Thus, unless the movement prohibiting means 55 prohibits the rotational movement of the rotationally movable plate 52 in the r1 direction relative to the window frame 3, the rotationally movable arm 51 is based on the application of the anti-movement force D2 to the rotationally movable plate 52. Thus, the rotational movement in the r1 direction relative to the rotationally movable plate 52 does not occur. In this respect, the rotationally movable arm 51 and the rotationally movable plate 52 are fixed to each other.

  For example, as shown in FIGS. 6 and 7, the movement prohibiting means 55 is swingable in the r3 and r4 directions on one of the rotary moving arm 51 and the rotary movable plate 52, in this example, on the rotary movable plate 52. An arm-like locked member 86 having a weight 88 which is connected and arranged away from the connected portion 85, and the other or window of the rotationally movable arm 51 and the rotationally movable plate 52. The frame 3 or the shoji 5, which is fixed to the vertical frame 14 in this example, and swayed in the r3 direction with respect to the rotary movable plate 52 based on the rotational movement of the rotary moving arm 51 in the r1 direction. And a locking member 87 for locking the locking member 86. Note that the locking member 87 is formed integrally with the mounting plate 58 in this example.

  For example, as shown in FIG. 6, the locked member 86 is provided on an arm-shaped main body 91 and a portion 85 on one end side of the arm-shaped main body 91 and is erected on the disk-shaped main body 71. A circular hole 93 through which the connecting pin 92 is inserted, and the other end of the arm-shaped main body 91 separated from the portion 85 in the direction intersecting the rotational movement locus in the r1 direction and the r2 direction in which the rotationally movable plate 52 rotates. The above-described weight 88 that is detachably mounted, the portion 85 of the arm-shaped main body 91, and the weight 88 are disposed, and the arm-shaped main body 91 is engaged with the locking member 87 when the arm-shaped main body 91 swings in the r3 direction. And a locked portion 94 to be stopped. The locked member 86 is connected to the rotatable plate 52 so as to be swingable in the r3 and r4 directions by inserting the connecting pin 92 through the circular hole 93. A bearing is interposed between the connecting pin 92 and the circular hole 93. The locked portion 94 includes a claw portion 95 extending in the lateral direction Y toward the locking member 87.

  For example, as shown in FIG. 7, the locking member 87 is formed along the movement trajectory in the r1 and r2 directions of the claw portion 95 of the locked member 86 arranged at a position swingable in the r3 direction. One of the long holes or slits, in this example, the arc-shaped slit 97 and the rotationally movable arm 51 and the rotationally movable plate 52, in this example, the slits 97 are arranged along the rotational direction of the rotationally movable plate 52. And a plurality of locking portions 98 formed on the outer surface. The plurality of locking portions 98 include a plurality of step portions 99 that lock the claw portions 95. Since the locking member 87 is formed integrally with the mounting plate 58, the locking member 87 is disposed in the window frame 3 so as not to move in the vertical frame 14.

  In such movement prohibiting means 55, when the rotationally movable plate 52 is rotationally moved in the r1 direction with respect to the window frame 3, the portion 85 of the locked member 86 connected to the rotationally movable plate 52 is also The weight 88 is rotationally moved in the r1 direction at the same speed as the rotational movement speed. If the speed is low, the weight 88 rotates in the r1 direction at substantially the same speed as the speed, whereas the speed is high. If there is, the weight 88 is rotated in the r1 direction at a speed lower than the speed in relation to the inertial mass of the weight 88. As a result, each of the one end and the other end of the locked member 86 is obtained. Thus, a difference is generated in the rotational movement amount in the r1 direction, and the locked member 86 swings in the r3 direction. When the r3 direction swings, the locked portion 94 is moved toward the plurality of locking portions 98 along with the swinging, and for example, as shown in FIG. Locked to any one of them. As described above, the movement prohibiting means 55 prohibits the rotational movement of the rotatable movable plate 52 in the r1 direction with respect to the window frame 3 by the locking of the locked member 86 by the locking member 87. The gradual increase of the anti-movement force D1 of the anti-movement force applying means 53 is restrained based on the prohibition of the rotational movement of the rotationally movable plate 52 by the movement prohibiting means 55.

  Note that the locked member 86 that is rocked in the r3 direction and locked to the locking member 87 rotates when the shock absorber 1 is placed vertically on the window opening and closing device 2 as in this example. When the movable plate 52 rotates and moves in the r2 direction with respect to the window frame 3 and the locked portion 94 is separated from the locking portion 98, the swing in the r4 direction is generated based on the gravitational mass of the weight 88. Although it can return to the original position, since the shock absorber 1 of this example includes the elastic biasing member 56, whether the shock absorber 1 is placed vertically on the window opening and closing device 2, for example, as shown in FIG. Regardless of whether or not it is placed flat as shown, the elastic biasing member 56 swings in the r4 direction based on the elastic biasing force in the r4 direction and returns to the original position.

  For example, as shown in FIG. 6, the elastic biasing member 56 is connected to the rotationally movable plate 52 via a connecting pin 45 erected on the disc-shaped main body 71 at one end and is arm-shaped at the other end. The coil spring 47 is connected to the locked member 86 through a connecting hole 46 provided in the main body 91. For example, as shown in FIG. 11, the coil spring 47 that is extended along with the swing of the locked member 86 in the r3 direction generates an elastic restoring force in the contraction direction, thereby elastically locking the locked member 86 in the r4 direction. It comes to energize. The elastic biasing member 56 causes the locked member 86 to swing in the r4 direction when the rocking force in the r3 direction of the locked member 86 is less than the elastic biasing force in the r4 direction of the coil spring 47. It can be returned to the position.

  As shown in FIG. 2, the window opening and closing device 2 further includes a locking tool (not shown) for releasably locking the shoji 5 in the opening closed position to the window frame 3. The shoji 5 is rotated by the operation when the shoji 5 is in the open closed position, and the shoji 5 is locked to the window frame 3, for example, the lower frame 13. For example, it may be rotatably attached to the lower arm 23 of the shoji 5.

  Hereinafter, the window opening and closing operation by the window opening and closing device 2 to which the shock absorber 1 is mounted as described above will be described.

  First, the locking of the shoji 5 to the window frame 3 by the locking tool is released by the operation. When the lock is released, the shoji 5 in the opening closed position shown in FIG. 2 is opened in the direction A because the center of gravity G is located on the side 10 in the building with respect to the rotation axis C1. The opening movement in the A direction that opens the opening 4 as shown in FIG. 9 is generated by the moment and the opening moving force in the A direction based on the elastic force of the coil spring 75 mainly of the shock absorber 1. In such a case, the rotation arm 36 rotates in the R1 direction around the rotation axis C1, and the end of the rotation arm 36 on the side of the window frame 3 is in the rotation of the rotation arm 36 in the R1 direction. The guide arm 37 linearly moves upward while being guided by the guide path 37, and the connecting arm 38 rotates about the rotation axis C4 based on the rotation of the rotation arm 36 in the R1 direction. Thus, the rotation axis C1 at the end on the shoji 5 side of the pivot arm 36 that rotates in the R1 direction is an approximate parallel movement from the inside 10 side of the building toward the outside 9 side of the building in the inside / outside direction X of the building. Then, a strictly linear motion is performed, and thereby the part 7 is also moved from the inside 10 side of the building toward the outside 9 side of the building in the inside / outside direction X of the building. The shock absorber 1 rotates the rotationally movable plate 52 and the rotationally movable arm 51 in the r2 direction mainly based on the elastic force of the coil spring 75, and causes the rolling roller 63 to follow the shoji 5 to rotate the rotationally movable arm 51. And the shoji 5 are kept in contact with each other.

  As described above, when the shoji 5 that opens and moves in the A direction reaches the opening opening position shown in FIG. 1, the center of gravity G is located on the same axis extending in the vertical direction V as the rotation axis C 1. 5 stands still in a state where it can be opened and closed in the A direction at the opening open position. The opening moving force based on the elastic force of the coil spring 75 of the shock absorber 1 is applied to the shoji 5 in the opening open position by the restricting pin 65 as shown in FIG. Is not granted. That is, when the shoji 5 is in the opening open position, the rotational movement arm 51 is in contact with the restriction pin 65, and therefore the rotational movement of the rotational movement arm 51 in the r2 direction is prohibited.

  Based on the airflow, when the shoji 5 at the opening open position is positive on the outside 9 side and negative on the inside 10 side of the shoji 5 with respect to the shoji 5, the shoji 5 is in the direction A based on the airflow. A closed movement occurs. When the shoji 5 is closed and moved, the flow rate of gas flowing between the outside of the building 9 and the inside of the building 10 decreases. When the addition of the closing movement force based on the airflow to the shoji 5 that has been closed and moved as described above disappears, the shoji 5 moves to open as described above and reaches the open position again. As described above, the window opening / closing device 2 performs natural ventilation by opening and closing the opening 4 of the shoji 5 based on the airflow.

  By the way, when the shoji 5 located on the opening opening position side with respect to the opening opening position or the opening closing position is subjected to a rapid closing movement by applying a large closing movement force when a strong wind is generated, The rotational movement arm 51 is also rapidly rotated in the r1 direction, and the rotationally movable plate 52 to which the rotational movement is transmitted from the rotational movement arm 51 via the anti-movement force applying means 54 is also r1 with respect to the window frame 3. Since the portion 85 of the locked member 86 is rapidly rotated in the r1 direction, the rotational movement amount in the portion 85 exceeds the rotational movement amount of the weight 88, so that the locked member 86 is rotated. As shown in FIG. 11, the to-be-latched member 86 is quickly locked by the locking member 87 as shown in FIG. As a result of the prohibition of rotational movement, As shown in FIGS. 10 and 12, the moving arm 51 is rotated in the r1 direction relative to the rotatable movable plate 52 by the closing movement of the shoji 5 based on the airflow, and thus imparts anti-movement force. The torsion spring 82 of the means 54 is compressed to produce a drag force D2 that is much greater than the drag force D1. This anti-movement force D2 is transmitted to the shoji 5 via the rotary movement arm 51 as an anti-movement force in the opening direction against the closing movement force in the A direction. Therefore, when a rapid closing movement occurs in the shoji 5, the rapid closing movement is quickly buffered by the shock absorber 1, and for example, a collision of the shoji 5 against the window frame 3 is prevented.

  In addition, the shoji 5 in the opening open position is closed and moved by the operation, and is disposed in the opening closing position, and is locked to the window frame 3 by the locking tool.

  According to the shock absorber 1 of this example, the moving force based on the opening / closing movement of the shoji 5 of the window opening / closing device 2 having the window frame 3 attached to the building and the shoji 5 that can be opened and closed with respect to the window frame 3. , A rotationally movable arm 51 that is moved by the addition, a rotationally movable plate 52 that is movably attached to the window frame 3 and is movably connected to the rotationally movable arm 51, and a rotationally movable plate 52 with respect to the window frame 3. The anti-movement force applying means 53 for applying the anti-movement force D1 against the movement based on the movement of the rotary movement plate 52 and the movement of the rotary movement plate 52 relative to the rotary movement arm 51 against the movement. Anti-movement force applying means 54 for applying anti-movement force D2 to the rotationally movable plate 52, and movement prohibiting means 55 for inhibiting the movement of the rotationally movable plate 52 relative to the window frame 3 based on the movement of the rotational movement arm 51. And The movement prohibiting means 55 is swingably connected to the rotatable movable plate 52 and has a weight member 86 having a weight 88 disposed away from the connected portion 85. And a locking member 87 that is fixedly attached to the window frame 3 and that locks the locked member 86 that swings with respect to the rotational movement arm 51 based on the movement of the rotational movement arm 51. The movement of the rotationally movable plate 52 relative to the window frame 3 is prohibited by the locking of the locked member 86 by the locking member 87, and therefore the rotationally movable plate of the locked member 86. 52 can cause a difference in moving speed between the portion 85 connected to the weight 52 and the weight 88, thereby causing the locked member 86 to oscillate and be locked to the locking member 87. Thus, the anti-movement of the anti-movement force imparting means 53 and 54 respectively. The desired buffering operation based on D1 and D2 can be performed, and it is not necessary to accurately set the angle at which the rotary moving arm 51 contacts the shoji 5, and the window opening and closing device 2 can be easily and quickly Can be installed.

  According to the shock absorber 1, the anti-movement force applying means 53 applies an anti-movement force D 1 smaller than the anti-movement force D 2 by the anti-movement force applying means 54 to the rotationally movable plate 52. The anti-movement force D1 by the force applying means 53 gradually increases in accordance with the gradual increase in the amount of movement of the rotary movement arm 51 in the r1 direction. The gradual increase of the anti-movement force D1 is freely rotatable by the movement prohibiting means 55. Since the movement of the rotationally movable plate 52 is not prohibited by the movement prohibiting means 55, the anti-movement force D1 in the movement with respect to the rotational movement arm 51 is prevented because the movement of the rotationally movable plate 52 is not prohibited by the movement prohibiting means 55. The rotationally movable plate 52 to which a greater anti-movement force D2 is applied can be made relatively stationary with respect to the rotationally movable arm 51, and the rotationally movable arm 51 can be moved by opening and closing the shoji 5 As a result, the anti-movement force applying means 53 can be mainly operated. As a result, the low-speed closing movement of the shoji 5 is allowed without causing a large anti-movement force D2 with respect to the closing movement of the shoji 5 in the low A direction. On the other hand, when the movement prohibiting means 55 prohibits the movement of the rotatable movable plate 52, the anti-moving force applying means 53 is not operated, so that the anti-moving force D2 by the anti-moving force applying means 54 can be generated. A large resistance against the closing movement in the high-speed A direction can be applied to the shoji 5 and the collision of the shoji 5 with the window frame 3 can be prevented.

  According to the shock absorber 1, the locking member 87 includes a plurality of lines arranged along the moving direction (directions r 1 and r 2) of the rotationally movable plate 52 as one of the rotationally movable arm 51 and the rotationally movable plate 52. Since the locking portion 98 is provided, if the shoji 5 is rapidly closed at any position between the opening open position and the opening closing position, the movement is prohibited immediately in response to the closing movement. It is possible to prohibit the movement by the means 55, and thus it is possible to generate the anti-movement force D2 promptly in response to the closing movement and to make the shoji 5 suitable for opening and closing.

  According to the shock absorber 1, the locked member 86 elastically biases the locked member 86 toward the r4 direction opposite to the r3 direction in which the locked member 86 swings based on the movement of the rotational movement arm 51. Since the urging member 56 is provided, it is possible to improve the degree of freedom of installation such as vertical placement and flat placement with respect to the window opening and closing device 2.
