Description

  The present invention relates to opening / closing of a sliding door or window (opening / closing body) such as an entrance sliding door or a sliding sash, and more particularly to a pinching prevention device for a sliding opening / closing body that prevents pinching of a finger or the like when the door is closed.

  Traditionally, sliding sliding doors and shojis (opening / closing bodies) have been used in the opening of houses, and the opening / closing body overlaps with the sliding sash, or the frame (fixed frame) side of the opening / closing body There was a case where a finger etc. were pinched between. In recent years, the ratio of the size of this opening / closing body increasing to improve the landscape and the paired glass with emphasis on crime prevention and heat insulation has increased, and the weight of the opening / closing body has increased accordingly. For this reason, there is a tendency that the danger when a finger or the like is pinched is increasing.

Various techniques have been developed in order to prevent a finger or the like from being caught. For example, Patent Document 1 discloses a technique in which two magnets are attached to the fixed frame side and the opening / closing body side, respectively, and the repulsive force of the magnet is used. Yes. In the apparatus of Patent Document 1, a rod-like member having a magnet attached to the tip between a fixed frame and an opening / closing body is installed on the fixed frame side, and another magnet is attached on the opening / closing body side. By slowly closing, the two magnets repel and the rod-shaped member can be retracted so that the opening / closing body is closed, and when the opening / closing body is quickly closed, the magnet cannot repel and the opening / closing body collides with the rod-shaped member and stops the opening / closing body. is there.
JP-A-8-82157

  However, since the magnet used in Patent Document 1 is weak against collision and a load is directly applied to the fixed shaft, the durability is low. And it can be imagined that it is very difficult to adjust the timing of the operation, that is, how fast to stop the opening and closing body, because the magnetic flux density of the magnetic body such as a magnet has a large variation. .

  The present invention has been made in view of the above problems, and it is an object of the present invention to provide a slide type opening / closing body pinching prevention device that controls sliding of the opening / closing body by mechanical control and has high durability.

The squeezing prevention device for a sliding opening / closing body according to the present invention is a squeezing prevention device for a sliding opening / closing body provided between a fixed frame and an opening / closing body that slides within the fixing frame, the fixing frame or the opening / closing body. A stopper that is held by at least one of them, and held by at least the other of the fixed frame or the opening / closing body, and engages with the stopper and retracts from the stopper before the opening / closing body contacts the fixing frame. a first movable body that moves in a direction, is held in at least the other of the fixed frame or the movable member, and engages with the stopper in conjunction with the movement in the direction of the retreat of the first movable body a second movable body that moves from a position for restricting the slide in time delay position that does not regulate the slide does not engage with the stopper, and the second movable member and the first movable member In conjunction with, and having a a time delay generating member for generating said time delay.

  According to the present invention, the stopper and the first movable body are engaged with each other before the opening / closing body contacts the fixed frame, and then the second movable body is engaged with the stopper with a time delay. Then, the sliding speed of the opening / closing body is regulated by reducing the sliding speed of the opening / closing body or stopping the sliding of the opening / closing body. The time delay is generated by a time delay generating member located between the first movable body and the second movable body, and the opening / closing body in which sliding is restricted cannot contact the fixed frame, and the time delay between the opening / closing body and the fixed frame It becomes difficult to pinch fingers between them.

  The time delay generating member used in the slide type opening / closing body pinching prevention device of the present invention includes a first urging member for urging the first movable body in a direction to engage with the stopper, and the second movable body. And a second urging member that urges the stopper in a direction to engage with the stopper, and one end of the first urging member is preferably engaged with the second movable body. The time delay generating member is composed of two urging members, and one end of the first urging member is engaged with the second movable body, whereby the two urging members cooperate to generate a time delay. Thereby, the 2nd movable body can regulate or permit the slide of an opening-and-closing body. Thus, since it is a simple structure which makes only two urging | biasing members cooperate, it is easy to control mechanically.

  In the first urging member and the second urging member, it is preferable that the urging force of the first urging member is stronger than the urging force of the second urging member.

  The slide opening / closing body pinching prevention device of the present invention further includes a bracket for holding the second movable body via the second urging member, and the bracket is extended by the second urging member. It is preferable that the rotation center part of the rotating second movable body has a groove that can move along the sliding direction of the opening / closing body. If the force of the first urging member that moves in the direction in which the first movable body retracts from the stopper and the second movable body is larger than the urging force of the second urging member, the second movable body retracts from the stopper. It is movable. The second movable body is movable around the center of rotation. Therefore, the collision load when the second movable body is engaged with the stopper is received by the rotation center portion and the end portion in the traveling direction of the opening / closing body of the groove of the bracket with which the rotation center portion is engaged. Therefore, after the second movable body is engaged with the stopper, the rotation center portion of the second movable body can escape in the direction opposite to the traveling direction along the groove, thereby reducing the load on the rotation center portion and the end of the groove. be able to. Thereby, damage of the rotation center part of the 2nd movable body and the groove | channel of the bracket which supports it can be avoided, and a highly durable apparatus can be provided.

  Further, when the second movable body engages with the stopper and the center of rotation of the second movable body moves along the groove and escapes in the opposite direction, the bracket receives a collision load when the second movable body engages with the stopper. It is preferable to have an impact absorbing member that absorbs by absorbing a part of the second movable body. As a result, the second movable body that has moved in the opposite direction absorbs the collision load by the shock absorbing member and is difficult to return to the traveling direction, and the shock absorbing member is rebounded from the end of the groove in the traveling direction side. I can prevent it.

  In the stopper used in the slidable opening / closing body pinching prevention device of the present invention, the second movable body is engaged with the inclined engagement surface that is engaged with the first movable body and inclined with respect to the sliding direction. A passing line in which the first movable body engages with the inclined engagement surface and a passing line in which the second movable body engages with the load receiving engagement surface are in a sliding direction. Are preferably parallel to each other. Since the inclined engagement surface of the stopper is inclined with respect to the sliding direction, the first movable body can be moved in a direction in which it can be retracted from the stopper after engagement, and the first urging force is against the urging force of the first urging member. A load is applied to the member. And the 2nd movable body which a 1st biasing member engages can be moved to the direction which retracts | saves from a stopper with time delay. In addition, by making the passage line of the first movable body and the passage line of the second movable body parallel to each other along the slide direction, the first movable body does not engage with the load receiving engagement surface but becomes the inclined engagement surface. The second movable body engages with the load receiving engagement surface without engaging with the inclined engagement surface. Therefore, after the first movable body is engaged with the inclined engagement surface, the second movable body can be engaged with the load receiving engagement surface with a time delay, so that sliding of the opening / closing body can be restricted or permitted. .

  It is preferable that the stopper used in the device for preventing pinching of the sliding opening / closing body of the present invention has a position adjusting unit that can change the position of the inclined engaging surface with respect to the load receiving engaging surface in the sliding direction. By adjusting the position of the inclined engaging surface in the sliding direction by the position adjusting unit, the distance between the inclined engaging surface and the load receiving engaging surface can be adjusted in the sliding direction. That is, it is possible to set how much the opening / closing body is regulated by the distance of both surfaces. For example, the closer the both surfaces are, the more the opening / closing body slides are restricted when the opening / closing body speed is faster, and the farther the both surfaces are, the farther the opening / closing body slides are restricted even when the opening / closing body speed is slower. The position adjustment of the inclined engagement surface by the position adjustment unit is very practical because the setting can be easily changed in consideration of the type of the opening / closing body, the installation location, the installation situation, and the like.

  According to the slidable opening / closing body pinching prevention device of the present invention, when the opening / closing body slides in the closing direction, the stopper and the first movable body are engaged before the opening / closing body abuts the fixed frame, and then the time is delayed. Since the second movable body engages with the stopper to reduce the sliding speed of the opening / closing body, or the sliding of the opening / closing body is stopped to regulate the sliding of the opening / closing body, It is difficult to pinch your fingers.

  The time delay until the first movable body engages with the stopper and the second movable body engages with the stopper is linked with the first urging member and the second urging member, which are time delay generating members. It is easy to control mechanically with a simple configuration.

  And the apparatus of this invention has the bracket which hold | maintains a 2nd movable body via the 2nd biasing member, The groove | channel which supports the rotation center part of a 2nd movable body is formed in the bracket. Since this groove opens along the direction in which the opening / closing body slides, when the second movable body and the stopper are engaged, the center of rotation of the second movable body can move in the reverse direction of the groove and rotate. The load on the center and groove is relaxed. Therefore, breakage of the rotation center portion of the second movable body and the groove of the bracket that supports the second movable body can be avoided, and a highly durable device can be provided.

Furthermore, the second movable body that has moved in the opposite direction has the impact absorbing member that absorbs the collision load when the bracket is in contact with a part of the second movable body and the second movable body is engaged with the stopper. The impact absorbing member absorbs the collision load, making it difficult to return to the traveling direction, and preventing the center of rotation from bouncing back to the end of the groove in the traveling direction side. Since it has a mating surface, the first movable body can move in such a direction that it can slide away from the stopper by sliding on the inclined engagement surface. Furthermore, since it has the load receiving engagement surface with which the 2nd movable body engages, the 2nd movable body engages with a load receiving engagement surface, and receives the load of the collision of an opening-and-closing body. Then, the first movable body receives the load by making the passage line through which the first movable body passes the stopper and the passage line through which the second movable body passes the stopper parallel by the sliding of the opening / closing body along the sliding direction. The second movable body can engage with the load receiving engagement surface without engaging with the inclined engagement surface without engaging with the engagement surface. Thereby, after the first movable body is engaged with the inclined engagement surface, the second movable body can be engaged with the load receiving engagement surface with a time delay, and thus the sliding of the opening / closing body can be restricted or permitted. it can.

  In addition, since the stopper includes a position adjusting unit that allows the stopper to change the position of the inclined engagement surface in the sliding direction, the distance in the sliding direction between the inclined engagement surface and the load receiving engagement surface can be changed. That is, it can be set so that both sides are closer or further away, and it is possible to set how much the opening / closing body is regulated by the distance between both sides. For example, the closer the both surfaces are, the faster the opening / closing body is regulated, and the farther the both surfaces are, the more the opening / closing body is regulated at a slower speed. Therefore, since the setting can be changed each time in consideration of the type (size and weight) of the opening / closing body, the installation location, the installation situation, and the like, it is possible to provide a very practical device for preventing a finger or the like from being caught.

  The squeezing prevention device for the sliding opening / closing body according to the embodiment of the present invention is attached to an opening that can be opened / closed of a front door or a window that slides in a horizontal direction such as a sliding door of a house entrance or a sliding sash of a window. Can do. Hereinafter, the case where the opening / closing body is closed will be described. The direction in which the opening / closing body slides in order to close the opening is referred to as “traveling direction”, and both the traveling direction of the opening / closing body and its opposite direction are referred to as “sliding direction”.

The slide type opening / closing body pinching prevention device 11 of the first embodiment is installed on the left side of the upper collar 221 in FIG. 1 in which the opening / closing body 22 is closed.

  The slide type opening / closing body pinching prevention device 11 according to the first embodiment includes a stopper 3, a bracket 4, a first movable body 5, a second movable body 6, and a time delay generating member 7.

  As shown in FIG. 2, the stopper 3 is fixed to the inner peripheral side of the fixed frame 21 so as to protrude toward the opening / closing body 22. Specifically, the device 11 of the first embodiment is disposed above the side where the opening / closing body 22 is closed and comes into contact with the fixed frame 21 before the opening / closing body 22 contacts the fixed frame 21 and the opening / closing body 22 is closed. It is a position that can function. When the opening / closing body 22 is slid in the left direction and closed, it is located on the left side of the upper collar 221 of the fixed frame 21. The stopper 3 includes a movable stopper 31 formed with an inclined engagement surface 311 that is inclined in a straight line with respect to the traveling direction of the opening / closing body 22 and a load receiving engagement surface 321 that is perpendicular to the traveling direction. And a fixed stopper 32 formed thereon. The movable stopper 31 is located closer to the traveling direction than the fixed stopper 32. As shown in FIG. 5, the movable stopper 31 and the fixed stopper 32 have different surface positions in the thickness direction of the opening / closing body 22 (fixed frame 21) so that both surfaces do not overlap in the traveling direction. It is attached to the fixed frame 21. In FIG. 5, a movable stopper 31 is attached to the front side, and a fixed stopper 32 is attached to the back side. Note that the positions of the movable stopper 31 and the fixed stopper 32 in the thickness direction may be reversed.

  The movable stopper 31 further includes a position adjusting unit 312 that can adjust the position of the inclined engaging surface 311 by changing the position in the sliding direction. In FIG. 5, the position adjustment unit 312 includes a long hole-shaped opening 312 a extending in the vertical direction along the sliding direction and a bolt 312 b that passes through the opening 312 a and fixes the movable stopper 31 to the fixed frame 21. Have. If the movable stopper 31 is moved in the sliding direction and the movable stopper 31 is fixed with the bolt 312b, the inclined engagement surface 311 can be set at an arbitrary position in the sliding direction. The position adjusting unit 312 may be one in which the opening 312a penetrates not to the fixed frame 21 but to the fixed stopper 32 and is fixed to the fixed stopper 32 with a bolt 312b.

  The fixed stopper 32 is attached to the fixed frame 21 with two bolts 322.

  Returning to FIG. 2, the bracket 4 is fixed above the opening / closing body 22, and a rotation support portion 41 that engages with a rotation center portion 610 of the second movable body 6 described later, and a time delay generating member 7 described later. It has a first engaging portion 42 with which one end of a two spring (second urging member) 72 is engaged, and an impact absorbing member (not shown) that abuts against a part of a second movable body to be described later and absorbs an impact. . In FIG. 2, only a part of the bracket 4 is shown.

  The 1st movable body 5 is the shape extended in the up-down direction in FIG. 2, and the 2nd engagement with which the end of the 1st spring (1st biasing member) 71 of the time delay production | generation member 7 mentioned later is engaged. And a straight inclined slide portion 512 that engages with the inclined engagement surface 311 and has an inclination angle substantially the same as the inclination angle of the inclined engagement surface 311. The first movable body 5 is biased in a direction (upward direction, arrow H1 direction) in which the inclined slide portion 512 is engaged with the inclined engagement surface 311 by the first spring 71 (a tension spring), and the inclined slide portion 512 is energized. The upper end portion with the protrusion protrudes upward from the upper end surface of the upper collar 221 of the opening / closing body 22. Then, after the inclined slide portion 512 is engaged with the inclined engagement surface 311, the first movable body 5 moves in the direction of retreating from the stopper 3 (downward direction, arrow H2 direction).

  The second movable body 6 includes a rotation center portion 610 at an end portion extending downward in the traveling direction, a third engaging portion 611 and a fourth engaging portion 612 in the middle of the lower portion, and a fixed frame 21 side on the opposite side in the traveling direction. A load receiving portion 613 is provided on the upper side and extended, and a bracket contact portion 614 is provided on the opposite surface.

  The rotation center portion 610 engages with the rotation support portion 41 of the bracket 4. The third engaging portion 611 is located closer to the traveling direction than the center portion in the sliding direction, and the other end of the first spring 71 of the time delay generating member 7 described later is engaged. The fourth engagement portion 612 is located on the opposite side of the traveling direction from the third engagement portion 611, and the other end of the second spring 72 of the time delay generation member 7 described later is engaged. The load receiving portion 613 has a surface that is positioned above the opposite side of the traveling direction and perpendicular to the sliding direction toward the traveling direction, and engages with the load receiving engagement surface 321 of the fixed stopper 32 of the stopper 3. A buffer member (not shown) that absorbs an impact at the time of engagement is fixed. The bracket contact portion 614 is located on the end surface on the opposite side in the traveling direction, that is, on the opposite side of the load receiving portion 613, and contacts the shock absorbing member (not shown) of the bracket 4.

  The second movable body 6 is urged by the second spring 72 in the direction of engagement with the stopper 3 (arrow H3 direction), and the load receiving portion 613 is positioned above the upper end surface of the upper collar 221 of the opening / closing body 22. Then, the opposite side of the traveling direction in which the bracket contact portion 614 is formed around the rotation center portion 610 swings due to the expansion and contraction of the second spring 72.

  As shown in FIG. 5, the inclined slide portion 512 of the first movable body 5 passes through the movable stopper 31 along the line 512 </ b> L by the sliding of the opening / closing body 22, and the load receiving portion 613 of the second movable body 6 is slid on the opening / closing body 22. Passes through the fixed stopper 32 along the line 613L. The line 512L and the line 613L are substantially parallel along the sliding direction. That is, the inclined slide part 512 is positioned on the near side in the thickness direction from the load receiving part 613. By doing so, the inclined slide portion 512 does not engage with the load receiving engagement surface 321 but engages with the inclined engagement surface 311, and the load receiving portion 613 engages with the load receiving engagement surface 321 to 2 The movable body 6 can regulate the sliding of the opening / closing body 22.

  The time delay generating member 7 includes a first spring (first urging member) 71 and a second spring (second urging member) 72. One end of the first spring 71 is engaged with the third engagement portion 611 of the second movable body 6, and the other end is engaged with the second engagement portion 511 of the first movable body 5. Is a tension spring that urges the stopper 3 in the direction of engagement with the stopper 3 (the direction of the arrow H1). One end of the second spring 72 is engaged with the first engaging portion 42 of the bracket 4, the other end is engaged with the fourth engaging portion 612 of the second movable body 6, and the second movable body 6 is engaged with the stopper 3. Is a tension spring that is biased in the direction of engagement with (in the direction of arrow H3).

  The first spring 71 extends because the inclined slide portion 512 of the first movable body 5 engages with the inclined engagement surface 311 of the stopper 3 and the first movable body 5 moves in the direction of the arrow H2, and the other end engages. The second movable body 6 is pulled in the direction of arrow H4. The second spring 72 extends when the second movable body 6 moves in the arrow H4 direction. Therefore, the biasing force of the first spring 71 is stronger than the biasing force of the second spring. By setting the first spring 71 and the second spring 72 as described above, the time delay generating member 7 generates a time delay by extending the first spring 71 and then the second spring 72. .

  Next, the operation of the slidable opening / closing body pinching prevention device 11 according to the first embodiment will be described. FIG. 2 is a diagram showing a state where the opening / closing body 22 is slid to close the opening, and the opening / closing body 22 is slid to the left. At this time, the first movable body 5 is urged in the arrow H1 direction by the first spring 71, and the second movable body 6 is urged in the arrow H3 direction by the second spring 72. The second spring 72 is balanced.

  Then, the case where the opening / closing body 22 slides quickly in the traveling direction (a dangerous speed when a finger or the like is sandwiched between the fixed frame 21 and the opening / closing body 22 when the opening / closing body 22 contacts the fixed frame 21) is shown in FIG. Is shown in First, the inclined slide portion 512 of the first movable body 5 is engaged with the inclined engagement surface 311 of the stopper 3. Since the inclined engagement surface 311 is inclined with respect to the traveling direction of the opening / closing body 22, the inclined slide portion 512 slides on the inclined engaging surface 311, and the first movable body 5 moves downward while moving in the traveling direction. Go down. Therefore, a load is applied to the first spring 71 engaged with the first movable body 5, and the first spring 71 pulls the second movable body 6. Then, the load of the first spring 71 becomes larger than the urging force of the second spring 72, and the second movable body 6 rotates clockwise around the rotation center portion 610 in the direction opposite to the traveling direction, and moves in the direction of arrow H4. To do. However, if the sliding speed of the opening / closing body 22 is fast and the time for the load receiving portion 613 to reach the load receiving engagement surface 321 is short, the load receiving portion 613 engages with the load receiving engagement surface 321 with a time delay. Then, the second movable body 6 is rebounded in the direction opposite to the traveling direction, and the bracket contact portion 614 of the second movable body 6 contacts the impact absorbing member of the bracket 4. As a result, the load receiving portion 613 of the second movable body 6 and the impact absorbing member of the bracket 4 receive a collision load of the opening / closing body 22, and the opening / closing body 22 fixed to the bracket 4 moves both in the traveling direction and in the opposite direction. Can not slide and stops.

  Next, FIG. 4 shows a case where the opening / closing body 22 is slowly slid in the traveling direction and closed. First, the inclined slide portion 512 of the first movable body 5 is engaged with the inclined engagement surface 311 of the stopper 3. Since the inclined engagement surface 311 is inclined with respect to the traveling direction of the opening / closing body 22, the inclined slide portion 512 slides on the inclined engaging surface 311, and the first movable body 5 moves downward while moving in the traveling direction. Go down. Therefore, a load is applied to the first spring 71 engaged with the first movable body 5, and the first spring 71 pulls the second movable body 6. Then, the load of the first spring 71 becomes larger than the urging force of the second spring 72, and the second movable body 6 rotates clockwise around the rotation center portion 610 in the direction opposite to the traveling direction, and moves in the direction of arrow H4. To do. The sliding speed of the opening / closing body 22 is slower than the time delay until the load receiving portion 613 of the second movable body 6 is engaged with the load receiving engagement surface 321 of the stopper 3, and the load receiving portion 321 is connected to the load receiving engagement surface 321. If the time required for 613 to reach is long, the load receiving portion 613 moves (lowers) in the arrow H4 direction so that it cannot engage the load receiving engagement surface 321. Therefore, the inclined slide portion 512 of the first movable body 5 finally slides below the movable stopper 31 from the inclined engagement surface 311 of the movable stopper 31, and the opening / closing body 22 advances without stopping the sliding of the opening / closing body 22. It is completely closed in contact with the fixed frame.

  According to the slidable opening / closing body pinching prevention device 11 of the first embodiment, before the opening / closing body 22 comes into contact with the fixed frame 21, the inclined engaging surface 311 of the movable stopper 31 of the stopper 3 and the inclination of the first movable body 5 are arranged. After the sliding part 512 is engaged, the sliding speed of the opening / closing body 22 is delayed by the time delay generating member 7, and the load receiving part 613 of the second movable body 6 is brought into contact with the load receiving engagement surface 321 of the fixed stopper 32 of the stopper 3. Since the sliding of the opening / closing body 22 is restricted by engaging and reducing the sliding speed of the opening / closing body 22 or stopping the sliding, it is difficult to pinch a finger or the like between the opening / closing body 22 and the fixed frame 21.

  And the time delay production | generation member 7 which produces | generates a time delay is comprised by the 1st spring 71 and the 2nd spring 72, and it is easy to control by the simple mechanical mechanism using the urging | biasing force of a spring.

  In addition, since the stopper 3 includes the position adjusting unit 312 that can change the position of the inclined engagement surface 311 in the sliding direction, the distance in the sliding direction between the inclined engagement surface 311 and the load receiving engagement surface 321 can be adjusted. Thereby, when both surfaces are adjusted to a closer distance, the opening / closing body 22 is regulated at a higher speed, and when both surfaces are adjusted to a longer distance, the opening / closing body 22 is also regulated at a slower speed. Adjustment is possible. Therefore, since it can be adjusted each time the apparatus is installed in consideration of the type (size and weight) of the opening / closing body 22, the installation location, the installation situation, etc., a very practical apparatus for preventing pinching of fingers or the like can be provided. .

(Example 2)
The slide type opening / closing body pinching prevention device 12 of the second embodiment is substantially the same as the configuration of the slide type opening / closing body pinching prevention device 11 of the first embodiment, and in the direction in which the second movable body 6 is engaged with the stopper 3. The configuration of the biasing second spring 72 and the configuration of the bracket 4 are partially different. Detailed description of the same configuration as that of the first embodiment will be omitted.

  As shown in FIGS. 6A and 6B, the bracket 4 further includes a groove 43 that extends in the direction opposite to the traveling direction from the rotation support portion 41 formed on the traveling direction side. And since the 1st engaging part 42 of the bracket 4 is formed in the advancing direction side rather than the 3rd engaging part 611 of the 2nd movable body 6, the 2nd spring 72 of the time delay production | generation member 7 is with respect to the advancing direction. It becomes the composition which can be attached diagonally. Therefore, the second movable body 6 comes into contact with the rotation support portion 41 at the end of the groove 43 in the traveling direction.

  The inclined slide part 512 of the first movable body 5 has an arc shape. The inclined slide portion 512 may be a straight inclined surface as in the first embodiment, and may be any shape that can move the inclined engagement surface 311 of the movable stopper 31 of the stopper 3. And the rotation center part 610 of the 2nd movable body 6 is a rod-shaped member, and is bridged by the bracket 4 in the thickness direction.

  FIG. 6A shows a state in which the sliding of the opening / closing body 22 is stopped by the squeezing prevention device 12 of the sliding opening / closing body of the second embodiment when the opening / closing body 22 slides in the traveling direction at a high slide speed. ing. In the drawing, the solid line indicates before the inclined slide portion 512 of the first movable body 5 is engaged with the inclined engagement surface 311 of the stopper 3, and after engagement is indicated by a two-dot broken line. As in the first embodiment, if the sliding speed of the opening / closing body 22 is fast and the time for the load receiving portion 613 to reach the load receiving engagement surface 321 is short, the time delay generation is performed after the inclined slide portion 512 is engaged with the inclined engagement surface 311. The load receiving portion 613 engages with the load receiving engagement surface 321 with a time delay due to the member 7. Then, the second movable body 6 is bounced back in the traveling direction, and the bracket contact portion 614 of the second movable body 6 contacts the impact absorbing member 44 of the bracket 4. As a result, the load receiving portion 613 and the shock absorbing member 44 receive a collision load of the opening / closing body 22, and the opening / closing body 22 fixed to the bracket 4 cannot slide in the traveling direction or the opposite direction and stops.

  And the state when the opening-and-closing body 22 slides in the advancing direction slowly is shown by FIG. In the drawing, the solid line indicates before the inclined slide portion 512 of the first movable body 5 is engaged with the inclined engagement surface 311 of the stopper 3, and after engagement is indicated by a two-dot broken line. As in the first embodiment, the load receiving portion 613 of the second movable body 6 is loaded with the load receiving engagement surface of the stopper 3 after a time delay after the inclined slide portion 512 of the first movable body 5 is engaged with the inclined engagement surface 311 of the stopper 3. Since the second movable body 6 is movable in the direction of arrow H4 before 321, the load receiving portion 613 and the load receiving engagement surface 321 are not engaged. Therefore, the inclined slide portion 512 of the first movable body 5 also finally slides below the movable stopper 31 from the inclined engagement surface 311, and the opening / closing body 22 continues to advance in the traveling direction without stopping the sliding of the opening / closing body 22. It can be completely closed by contacting the fixed frame.
