Description

  The present invention relates to an opening / closing body shock absorber capable of forcibly and gently closing an opening / closing body such as a sliding door or a drawer when opening, and a method for attaching / detaching the opening / closing body shock absorber. About.

  A conventional opening / closing body shock absorber is attached to, for example, a sliding door rail on the building side, two captured members respectively disposed on both the open side and the closed side of the sliding door rail, and attached to the sliding door side. And a capture pull-in mechanism for capturing the capture member and retracting the sliding door in the opening direction or the closing direction. This capture pull-in mechanism extends in the longitudinal direction of the sliding door rail and extends in the opening / closing direction of the sliding door, and can be rotated around a rotation axis at each of its open and closed ends. An axially supported capture member (hook) is provided.

  These open side and closed side capture members can be slid in the open / close direction inside the capture pull-in mechanism. The open side and closed side capture members are connected in the opening and closing direction by a spring, and are attracted to each other by the spring force of the spring. Furthermore, the open side and closed side capture members are connected in the opening and closing direction by dampers for buffering the spring forces attracting each other.

  The closed-side capture member is for capturing the closed-side captured member. In the state before the capture (the state where the capture is released), the capture member on the closed side is locked (locked) to the main body (casing) of the capture pull-in mechanism and cannot move in the opening / closing direction. Yes. When the sliding door is closed to a predetermined position from the locked state, the closed-side captured member and the closed-side capturing member come into contact with each other, and the capturing member rotates. At this time, the lock between the capturing member and the main body is released, and the capturing member can move in the opening and closing direction, and the closed capturing member captures the closed captured member.

  On the other hand, the open-side capture member is for capturing the open-side captured member. The open side capture member and the capture target member have the same configuration as the closed side. When the sliding door is opened to a predetermined position, the open side capture member rotates and the lock is released. Can move in the opening and closing direction, and the open-side capture member captures the open-side captured member.

  In the opening / closing body shock absorber having such a configuration, the sliding door does not reach the predetermined position on either the closed side or the open side, and the capture member on the open side or the closed side does not capture any captured member Then, both of the capturing members are locked to the main body of the capturing / retracting mechanism, and neither capturing member can move in the opening / closing direction.

  On the other hand, when the sliding door is closed to a predetermined position on the closed side and the closed-side capture member captures the captured member, the closed-side capture member is unlocked, but the open-side capture member is captured and retracted. Therefore, the captured closed member to be captured is attracted to the open side by the urging force of the spring. As a result, the sliding door is forced to move in the closing direction when the sliding door is closed.

  Conversely, when the sliding door is opened to a predetermined position on the open side and the capture member on the open side captures the captured member, the lock on the capture member on the open side is released, but the capture member on the closed side is captured and retracted. Since it is locked to the main body of the mechanism, the captured member to be captured on the open side is drawn toward the closing side by the biasing force of the spring. Thereby, a sliding door comes to move to an opening direction compulsorily at the time of the opening.

  Further, when the sliding door is opened or closed, the above-described damper buffers the urging force of the spring, so that the sliding door opens and closes gently (see, for example, Patent Document 1).

  Hereinafter, an opening / closing body shock absorber 10 according to an embodiment of the present invention will be described in detail with reference to the drawings. In addition, this Embodiment demonstrates what uses the opening-and-closing body buffer device 10 for a sliding door apparatus.

  FIG. 1 is a front view of an upper part of a sliding door 2 provided with an opening / closing body shock absorber 10 according to the present invention, and shows a state in which the sliding door 2 is located in the middle in the opening / closing direction (left and right direction on the paper). 2 is a front view showing a state where the sliding door 2 is closed from the state shown in FIG. 1, and FIG. 3 is a front view showing a state where the sliding door 2 is opened from the state shown in FIG. FIG. 4 shows the capture / retraction mechanism 20 as a single unit, and is a perspective view corresponding to a state where the sliding door 2 is located in the middle (the state shown in FIG. 1). 5 is a perspective view corresponding to a state in which the sliding door 2 is closed (the state shown in FIG. 2), and FIG. 6 corresponds to a state where the sliding door 2 is opened (the state shown in FIG. 3). FIG.

In addition, the “front side (front direction)” used in the following description means the left side (door closing side) in FIG. 1, and the “rear side (rear direction)” means the right side (door opening) in FIG. Side). Further, the “up and down, left and right” directions are directions when the opening / closing body shock absorber 10 of FIG. 1 is viewed from the front side.
Furthermore, “when closing” used in the present specification refers to a period from when the opening / closing body shock absorber 10 moves to the position where the sliding door is completely closed from the position where the opening / closing body shock absorber 10 is captured. On the contrary, “when opening” means a period from the position where the opening / closing body shock absorber 10 captures the capture target member 11 on the open side until the sliding door is fully opened.

  The sliding door device shown in FIGS. 1 to 3 moves in the front-rear direction along the guide rail 1 extending in the front-rear direction (opening / closing direction) along the upper edge of the opening of the building. The sliding door 2 (opening / closing body) that opens and closes the opening portion and the opening / closing body shock absorber 10 that brakes the sliding door 2 when the sliding door 2 is opened or closed and guides the sliding door 2 to the open position or the closed position. .

  The opening / closing body shock absorber 10 includes a closed-side captured member 11 disposed on the front side of the guide rail 1, an open-side captured member 11 disposed on the rear side of the guide rail 1, and the guide rail 1. It is comprised with the capture drawing-in mechanism 20 which can drive | work along the front-back direction.

  As shown in FIG. 1, the two captured members 11 are formed in a convex shape having a protrusion 11 a that protrudes downward. These captured members 11 are respectively attached to predetermined positions on the front side and the rear side (positions for guiding the sliding door 2 in the opening / closing direction) in accordance with the structure of the capture pull-in mechanism 20.

  The catching / retracting mechanism 20 is accommodated inside the guide rail 1 having a U-shaped cross section whose lower side is open, and is attached so as to be movable along the front-rear direction of the guide rail 1. More specifically, the capture pull-in mechanism 20 is provided with guide rollers 21 (four on the front side and two on the rear side in FIGS. 1 to 3) on each of the front side portion and the rear side portion thereof. As the guide roller 21 rolls on the rolling surface 1 a of the guide rail 1, the catching and retracting mechanism 20 can freely move in the front-rear direction of the guide rail 1.

  In addition, a hanging portion 300, which will be described in detail later, is provided on the front side portion of the capturing and retracting mechanism 20. An upper end corner (an upper left corner of the drawing in FIG. 1) of the sliding door 2 is attached to the hanging portion 300, and the front end portion of the hanging door 2 is supported in a suspended manner. Accordingly, when the sliding door 2 is moved in the opening / closing direction (front-rear direction), the guide roller 21 of the capture pull-in mechanism 20 rolls on the guide rail 1, and the sliding door 2 opens and closes smoothly in the front-rear direction.

  In addition, although it is not the capture drawing-in mechanism 20, the suspension part 5 is attached also to the upper-end corner part of the right side of the sliding door 2. As shown in FIG. The suspension portion 5 supports the rear end portion of the suspension door 2 in a suspended manner, and the sliding door 2 is smoothly moved in the front-rear direction by a guide roller 21 that can roll the rolling surface 1 a of the guide rail 1. Will open and close.

  As shown in FIGS. 1 to 3 and FIGS. 4 to 6, the capture pull-in mechanism 20 is provided with a first catch portion 100 located on the front side and a second catch portion 150 located on the rear side. Yes. The first catch portion 100 is configured to be slidable in the front-rear direction inside the catching / retracting mechanism 20 and catches the protrusion 11a of the to-be-captured member 11 on the front side at a predetermined position when closed. Further, the second catch portion 150 is also slidable in the front-rear direction inside the capture pull-in mechanism 20, and captures the protrusion 11a of the rear captured member 11 at a predetermined position when opened (capture) Details of the operation will be described later).

  As shown in FIG. 1, in the capture pull-in mechanism 20, the first catch portion 100 and the second catch portion 150 are positioned between the two captured members 11 in a state where the sliding door 2 is positioned in the middle in the opening / closing direction. In this state, neither the first catch part 100 nor the second catch part 150 captures the protrusion 11a of the captured member 11. That is, in this state, the capture / retraction mechanism 20 is not functioning (standby state). In this standby state, the first catch portion 100 is positioned on the front end side of the capture pull-in mechanism 20 while being locked to the main body side of the capture pull-in mechanism 20 (details will be described later), and the second catch portion 150 is also locked. It is located in the rear end side of the capture drawing-in mechanism 20 in the state (refer FIG. 4).

When the sliding door 2 is moved from the standby state to the front side (the left side in FIG. 1, the door closing side), when the sliding door 2 is closed, the locking of the catch unit 100 described above is released, and the first catch unit 100 is moved to the front side. The to-be-captured member 11 is captured (door closed state, see FIG. 2).
In this door-closed state, as shown in FIG. 5, the first catch portion 100 captures the front captured member 11, and the center portion side (in the direction of arrow A) by the force of the spring 226 (see FIGS. 7 and 8). ) That is, the capture pull-in mechanism 20 acts to draw the captured member 11 to be captured toward the sliding door 2 side (the right side in FIG. 1 and the rear side). As a result, the sliding door 2 is forcibly moved in a relatively closing direction (left side in FIG. 1, front side) and is completely closed until the sliding door 2 comes into contact with the front door stop 3 as shown in FIG. Be able to. In this door-closed state, the second catch portion 150 is locked and remains at the same position as in the standby state.

On the other hand, when the sliding door 2 is moved from the standby state to the rear side (the right side in FIG. 1, the door opening side), when the sliding door 2 is fully opened, the above-described catch 150 is unlocked, 2 The catch part 150 catches the catching / retracting member 11 located on the rear side (door open state, see FIG. 3).
In this door open state, as shown in FIG. 6, the second catch portion 150 moves toward the center side (in the direction of arrow B) by the force of the spring 226 while capturing the rear-side captured member 11. That is, the capture pull-in mechanism 20 acts to pull the captured member 11 that has been captured toward the sliding door 2 side (left side in FIG. 1, front side). As a result, the sliding door 2 is forcibly moved in the relative opening direction (right side in FIG. 1, rear side), and as shown in FIG. 3, the sliding door 2 is completely in contact with the rear door stop 4. Will be opened. In this door open state, the first catch portion 100 is locked and stays at the same position as in the standby state.

  FIG. 7 is an exploded perspective view of the capturing / retracting mechanism 20 as viewed from above, and FIG. 8 is an exploded perspective view of the capturing / retracting mechanism 20 as viewed from below. Further, FIG. 9 is an enlarged view of the first catch part 100 in an exploded state, where (a) is an exploded perspective view seen from the upper right side, and (b) is an exploded perspective view seen from the lower left side. It is. FIG. 10 is an exploded perspective view of the second catch portion 150 as viewed from the rear obliquely lower side.

  As shown in FIGS. 4 to 6, 7, and 8, the capture pull-in mechanism 20 includes a first catch portion 100 that captures the protrusion 11 a of the front captured member 11 and a rear captured member 11. A second catch portion 150 to be captured and a pull-in portion 200 for pulling the catch portions 100 and 150 toward the center along the extending direction (front-rear direction) of the guide rail 1 are provided.

  The 1st catch part 100 is constituted as a link mechanism which operates according to the position of link pin 140 mentioned below. Specifically, as shown in FIGS. 7 and 8, particularly FIGS. 9A and 9B, the first catch portion 100 is in contact with the protrusion 11 a of the captured member 11 at a predetermined position. The first inclusion block that includes the block 110, the capture plate 120 that moves in the vertical direction to capture the protrusion 11a, and the contact block 110 and the capture plate 120 that move in the front-rear direction. 130, and the abutment block 110, the capture plate 120, and the first inclusion block 130 are configured by link pins 140 for operating as a link mechanism.

  The contact block 110 is formed in a mode in which the main body 111 is formed in a substantially rectangular parallelepiped shape and protrudes obliquely upward to the rear of the main body 111, and the upper portion of the contact block 110 protrudes above the upper surface of the main body 111. Part 112.

  The main body 111 has a hollow inside, and this hollow is formed so as to penetrate vertically. The capture plate 120 is inserted and assembled into the cavity from the lower opening. Further, the main body portion 111 is formed with an inclined hole 111a extending from the obliquely upper front side toward the obliquely lower rear side. The inclined hole 111a is formed so as to penetrate the body portion 111 in the left-right direction, and the link pin 140 is inserted when the first catch portion 100 is assembled.

  As shown in FIGS. 9A and 9B, a contact surface 112 a that rises upward from the upper surface of the main body 111 is formed on the front surface of the receiving portion 112. When the sliding door 2 reaches a predetermined position when the sliding door 2 is closed, the abutting surface 112a comes into contact with and is pressed against the protrusion 11a of the captured member 11 on the front side.

  Further, as shown in FIG. 9B, a spring receiving groove 112 b having a shape recessed in the front-rear direction is formed on the rear surface of the receiving portion 112. One end of the compression coil spring 113 is supported by the spring receiving groove 112b.

  The catch plate 120 is formed in a substantially rectangular shape, and is formed with catch claws 121 that protrude upward from the upper surface thereof. When the capture plate 120 is moved upward by the link mechanism, the capture claw 121 captures the protrusion 11a of the captured member 11 in the front-rear direction by the receiving portion 112 and the capture claw 121 described above. .

  A taper contact surface 121 a is formed on the rear surface of the catching claw 121. The tapered contact surface 121a is an inclined surface that is inclined from the lower side of the taper toward the upper front side. When the sliding door 2 is moved in the opening direction from the closed state (see FIG. 2), the protruding portion 11a of the captured member 11 comes into contact with the tapered contact surface 121a. Then, the protrusion 11a pushes down the catching claw 121 toward the obliquely lower front side which is a direction perpendicular to the tapered surface. Thereby, it cancels | releases from the state which caught the protrusion 11a, and comes to return to a standby state from a door closed state.

  In addition, the catch plate 120 is formed with an auxiliary claw 122 positioned on the front side of the catch claw 121. The auxiliary claw 122 captures the protrusion 11a between the capture claw 121 and the auxiliary claw 122 when the projection 11a cannot be captured by the capture claw 121 and the receiving portion 112 described above. Is provided.

The auxiliary claw 122 is configured so that the opening / closing body shock absorber 10 can close the sliding door 2 even when the captured member 11 is captured by the capture claw 121 and the auxiliary claw 122. More specifically, when the auxiliary claw 122 opens the sliding door 2 and is pressed forward by the projection 11a of the captured member 11, the auxiliary claw 122 bends downward to cause the captured member 11 to move. It escapes to the front side of the auxiliary claw 122.

  Further, the catch plate 120 is formed with an attachment hole 123 that is located below the catch claws 121 and penetrates in the left-right direction. The mounting hole 123 is a round hole having a diameter that is the same as or slightly larger than the outer diameter of the link pin 140, and a link pin 140, which will be described in detail later, is inserted into the mounting hole 123. As a result, the capture plate 120 moves together with the link pin 140 as the link pin 140 moves.

  As shown in FIGS. 7 and 8, particularly FIGS. 9A and 9B, the first inner block 130 includes an outer shell 131 formed in a substantially rectangular parallelepiped shape, and a rear end from the rear edge of the outer shell 131. It is comprised by the support part 132 which protrudes to the side, and the guide protrusions 133 and 134 which protrude toward the left and right outer side from the both right and left sides of the outer shell part 131, respectively.

  The outer portion 131 is hollow inside. The cavity is formed so as to penetrate vertically, and the contact block 110 is inserted and assembled into the cavity from the opening on the upper side. Further, the outer shell 131 is formed with a guide hole 131a extending in the vertical direction when viewed from the front. The guide hole 131a is formed so as to penetrate in the left-right direction of the outer shell part 131, and when the first catch part 100 is assembled, the inclined hole 111a of the contact block 110, the mounting hole 123 of the catch plate 120, and Together, the link pin 140 is inserted.

  In addition, a receiving surface 131b that rises up and down is formed at a rear end portion in the cavity of the outer shell portion 131. The other end portion of the compression coil spring 113 is supported on the receiving surface 131b in a state in which the contact block 110 is assembled in the first inclusion block 130.

  Further, a constricted portion accommodating groove 131c for accommodating a constricted portion 227a of a spring receiver 227 of a tension spring unit 225, which will be described in detail later, is formed in the lower rear portion of the outer shell portion 131 (under the receiving surface 131b). . The constricted portion receiving groove 131c regulates the position of the spring receiver 227 in the left-right direction and the front-rear direction in a state where the spring receiver 227 is assembled.

  The support portion 132 is formed with a mounting groove 132a extending in the vertical direction at the rear end thereof. A tip end portion of an output shaft 221a of a damper unit 221 described later in detail is inserted into the mounting groove 132a, and the mounting position in the left-right direction of the output shaft 221a is restricted.

  The guide protrusions 133 and 134 extend in the front-rear direction (the moving direction of the sliding door 2). These guide protrusions 133 and 134 are in a state in which the first inclusion block 130 is incorporated in the guide part 210 of the retracting part 200 described later, and the protrusions 218 of the guide part 210 described later in detail (FIG. 17A). , See FIG. 17B) and the groove 261 formed by the step 260, and slides back and forth along the groove 261. As a result, the first catch portion 100 moves in the front-rear direction with respect to the retracting portion 200.

  Further, the outer shell 131 is provided with slide protrusions 135 and 136 on both the front and rear sides.

A front portion of the attachment cover 401 is open, and the engagement claw 230 of the rear attachment block 250 is inserted through this opening. Engagement holes 401 b that engage with the engaging claws 230 are formed on both the left and right sides of the mounting cover 401. Thereby, the engagement claw 230 can be freely attached to and detached from the engagement hole 401b without using a fastening member such as a screw.
Further, the two guide rollers 21 are rotatably supported by a rotating shaft 402 that penetrates the mounting cover 401 from side to side.

  Next, the operation of the opening / closing body shock absorber according to the embodiment of the present invention and the operation of the link mechanism that functions by the link pin 140 will be described. FIG. 13A is a plan view of the capture pull-in mechanism, FIG. 13B is a front view of the capture pull-in mechanism, and FIG. 14 is a cross-sectional view taken along the line CC in FIG. FIGS. 15A and 15B are views for explaining the operation of the second catch portion, where FIG. 15A is an enlarged front view of the rear portion, and FIG. Furthermore, FIG. 16 is a figure explaining operation | movement of a 2nd catch part, Comprising: (a) is an enlarged front view of a rear side part, (b) is YY sectional drawing. FIGS. 17A and 17B are diagrams for explaining the operation of the second catch portion, where FIG. 17A is an enlarged front view of the rear portion, and FIG. 17B is a ZZ sectional view. FIG. 18 is a cross-sectional view of the second catch portion, where (a) is a state before the capturing member captures the captured member, and (b) is a diagram illustrating a state after capturing.

  Here, the operations of the first catch portion 100 and the second catch portion 150 and the operation of the link mechanism are the same except that the front-rear direction is reversed. Therefore, in the following description, the operation of the link mechanism in the second catch portion 150 will be described, and the description of the link mechanism of the first catch portion 100 will be omitted.

  In the standby state where the second catch portion 150 is not capturing the member 11 to be captured (see FIGS. 1, 4, 13A, 13B, and 14), the link pin 140 that operates the link mechanism is used. Is in the position of the ridge portion excision hole 219 in which the ridge portion 218 is notched in the front-rear direction. Further, the end portion 140 a of the link pin 140 passes through the notch portion 262 and is positioned below the upper surface of the protrusion 218. At this time, as shown in FIGS. 15A and 15B, the catch plate 120 of the second catch portion 150 is in a state of being lowered, and the lower portion of the catch plate 120 is the bottom portion of the guide portion 210. It protrudes downward from the square hole 217.

  Further, in this state, as shown in FIGS. 15A and 18A, the end portion 140a of the link pin 140 is a notch surface of the notch portion 262 formed by the protruding portion cutting hole 219. And in the front-rear direction. Thereby, the 2nd catch part 150 will be in the locked state so that it cannot move freely in the direction of order.

  When the sliding door 2 is moved from the standby state to the door opening side (rear side; H direction in FIG. 18A), as shown in FIG. 16A and FIG. The eleven protrusions 11a abut against the abutment surface 112a of the abutment block 110 of the second catch portion 150 and press the abutment block 110 forward. This pressing force E is the same as the force for opening the sliding door 2, and a large force is applied when trying to open the sliding door vigorously.

  When this pressing force E acts, the contact block 110 of the second catch portion 150 slides forward. At this time, since the contact block 110 compresses the compression coil spring 113, the pressing force E is buffered. Thereby, first, the force when opening the sliding door 2 is not transmitted to the second catch part 150 as it is, and a smaller force is applied.

  When the contact block 110 slides forward, the inclined hole 111a of the contact block 110 shown in FIG. 15 (a) moves forward as shown in FIG. 16 (a). Along the inclined hole 111 a and the guide hole 161 a of the second inner block 160, it is pushed upward in the F direction. Thereby, the capture plate 120 moves upward together with the link pin 140. In this state, as shown in FIGS. 16A and 18B, the protrusion 11a of the rear member to be captured 11 captures the receiving portion 112 of the contact block 110 and the capture plate 120 described above. It is captured in such a manner that the front and rear are sandwiched between the claws 121.

  Further, when the link pin 140 moves in the upper F direction, as shown in FIG. 16B, the link pin 140 is positioned above the upper surface of the ridge 218, so that the notch surface of the notch 262 of the ridge 218. The locked state is released. Accordingly, the lock of the second catch portion 150 is released, and the end portion 140a of the link pin 140 can freely slide in the front-rear direction while sliding on the upper surface of the ridge portion 218.

  Furthermore, the upward movement speed of the capture plate 120 can be slower than the movement speed of the contact block 110 because the length of the guide hole 131a is short based on the length of the inclined hole 111a. That is, the capture plate 120 moves upward at a speed slower than the speed at which the sliding door 2 is opened and closed (the movement speed of the contact block 110).

  In the unlocked state, as shown in FIG. 17A, the second catch portion 150 is biased toward the first catch portion 100 side (front side, direction G) by the tension spring force of the tension spring unit 225. Is done. More specifically, when the second catch portion 150 captures the protrusion 11a at the fixed position of the rear captured member 11, the operation is completed, and thereafter the tension spring unit 225 and the damper unit 221 operate. .

The second catch portion 150 moves in the G direction while capturing the captured member 11 on the rear side. In other words, the second catch portion 150 stays at the attachment position of the captured member 11 while capturing the captured member 11, and the entire capture pull-in mechanism 20 other than the second catch portion 150 moves relatively rearward. Moving. That is, the tension spring force of the tension spring unit 225 urges the sliding door 2 in a direction to forcibly open it. Thereby, as shown in FIG. 3, the sliding door 2 will be guide | induced to the state which the sliding door 2 opened completely.
Further, in the moving state described above, the spring force of the tension spring unit 225 is buffered by the damper unit 221 so that the sliding door 2 does not collide with the door stop 4 vigorously.

  Conversely, when the sliding door 2 is moved from the fully open state to the closing direction (when the sliding door is moved from the state of FIG. 3 to the closing direction), the operation is the reverse of the above-described operation. That is, when the sliding door 2 is moved to the front side, the protruding portion 11a of the rear-side captured member 11 comes into contact with the catching claw 121 of the catching plate 120, and the second catch portion 150 causes the tension spring 226 of the tension spring unit 225 to move. Move in the pulling direction. At this time, since the protrusion 11a presses the taper contact surface 121a of the catching claw 121, a force to push down the catching plate 120 is always applied to the catching plate 120 during the movement of the second catch 150 in the front-rear direction. This pushing down force is received by the protrusion 218 when the link pin 140 is on the protrusion 218, but when the link pin 140 reaches the position of the protrusion cutting hole 219, the link pin 140 It is pushed down through the notch 262 of the protrusion 218.

  In addition, when the above-described downward pressing force is applied, the end portion 140a of the link pin 140 is pressed onto the protruding portion 218, so that vibration is generated during the movement of the second catch portion 150. hard. Therefore, the vibration transmitted to the first catch portion 100 due to the movement of the second catch portion 150 can be suppressed to a low level, and malfunctions such as unlocking of the first catch portion 100 are less likely to occur.

Thereby, the capture plate 120 moves downward at the position of the ridge portion excision hole 219 (notch portion 262), and the capture state is released. Further, the end portion 140a of the link pin 140 is locked in the front-rear direction by coming into contact with the cut-out surface of the cut-out portion 262, so that the second catch portion 150 cannot freely move in the front-rear direction.
Further, the abutting block 110 is promoted (assisted) by the force of moving backward by the urging force of the compression coil spring 113. Thereby, the movement of the link mechanism at the time of release of capture is performed more smoothly.

Next, a method for attaching and detaching the capturing / retracting mechanism 20 of the opening / closing body shock absorber according to the embodiment of the present invention will be described in detail with reference to FIGS.
In addition, in the following description, what assembled the 1st catch part 100, the 2nd catch part 150, and the drawing-in part 200 (part except the suspension part 300 and the rear side guide roller part 400 from the capture drawing-in mechanism 20). , Called the capture pull-in mechanism main body T.

  FIG. 19 is a perspective view of a state in which the capture pull-in mechanism 20 is attached to the guide rail as viewed from the front obliquely lower side. 20 is a perspective view showing a state in which the mounting screw 213 is removed downward from the state shown in FIG. 19, and FIG. 21 is a perspective view showing the state where the front side of the catching / retracting mechanism main body T is suspended from the state shown in FIG. FIG. 22 is a perspective view illustrating a state in which the capture pull-in mechanism main body T is pulled out from the rear guide roller unit 400 from the state illustrated in FIG. 21. is there.

As shown in FIG. 11, the guide rollers 21 on the front side and the rear side of the catching and retracting mechanism 20 are attached so as to be placed on the inner bottom surface 1 a of the guide rail 1. As the guide roller 21 rolls along the longitudinal direction of the inner bottom surface 1a (longitudinal direction of the guide rail 1), the capturing and retracting mechanism 20 freely moves on the guide rail 1.

  From this state, the catching / retracting mechanism main body is left in the guide rail 1 while the hanging portion 300 to which the front guide roller 21 is attached and the rear guide roller portion 400 to which the rear guide roller 21 is attached are left in the guide rail 1. The part T is removed from the guide rail 1.

  First, as shown in FIG. 19, the sliding door 2 is removed from the hanging part 300, and the whole bottom part of the capture drawing-in mechanism 20 is made visible from the opening side where the sliding door 2 was attached. Next, as shown in FIG. 20, the mounting screw 213 that assembles the retracting part 200 and the hanging part 300 is removed from the lower side of the capturing and retracting mechanism 20 in the J direction. This operation can be easily performed because the tool can be used upward from the opening side to which the sliding door 2 is attached.

  The mounting screw 213 is inserted in the vertical direction (direction different from the moving direction of the sliding door 2) in order to make it easy to attach and detach from the lower side, but to receive an impact due to the momentum when the sliding door 2 is opened and closed. This is also for resisting the biasing force of the tension spring 226 of the tension spring unit 225. That is, in the method of fixing by fitting or the like in the same direction as the moving direction of the sliding door 2, these forces are applied when the sliding door 2 is guided in the opening and closing direction by the momentum when the sliding door 2 is opened and closed and by the tension spring 226. This is because there is a risk of disengagement. On the other hand, the rear guide roller portion 400 that does not support the sliding door 2 is not affected by the impact when the sliding door 2 is opened and closed and the urging force of the tension spring 226, and therefore fits in the same direction as the moving direction of the sliding door 2. It may be fixed by, for example.

  Next, as shown in FIG. 21, the suspending portion 300 provided with the guide roller 21 is left on the guide rail 1 as it is, and the capturing / retracting mechanism main body T and the rear guide roller portion 400 are moved to the rear side (K direction). Move together. As a result, the fitting (clamping) between the mounting block 240 and the clamping part 311 of the front guide roller part 310 is completely disengaged in the front-rear direction, and the hanging part 300 and the front side part of the capture pull-in mechanism main body T are removed.

  From this state, as shown in FIG. 21, the front portion of the catching and retracting mechanism main body T is rotated in the L direction around the rotation shaft 402 of the rear guide roller portion 400, and the front portion is lowered downward. This is because the guide rollers 21 of the rear guide roller portion 400 are configured in one row in the front-rear direction, and therefore can rotate around the rotation shaft 402.

  Then, as shown in FIG. 22, the capture pull-in mechanism main body T is removed so as to be pulled out in the lower M direction. At this time, the two left and right engaging claws 230 can be disengaged from the engaging holes 401b by bending the engaging claws 230 inward by elasticity. As a result, the rear end portion of the capture pull-in mechanism main body T can be pulled out (removed from fitting) from the rear guide roller portion 400.

Further, as a matter of course, the capture pull-in mechanism main body T is fitted into the rear guide roller portion 400 by pushing the rear side portion of the capture pull-in mechanism main body T into the rear guide roller portion 400, that is, the reverse procedure of the above-described removal procedure. By fixing the front side portion of the capture pull-in mechanism main body T with the mounting screw 213, it can be easily attached.
As a result, it is possible to remove and attach the capture pull-in mechanism main body T to the guide rail 1 while leaving the suspending portion 300 and the rear guide roller portion 400.

  According to the opening / closing body shock absorber according to the embodiment of the present invention, the guide roller 21 is disposed before and after the capture pull-in mechanism main body T, and the guide roller 21 is assembled to the guide rail 1 in the state where the guide roller 21 is assembled. Since the mechanism main body T is configured to be detachable from the guide roller 21, the guide rail 1 attached to the upper edge or the lower edge of the opening of the building can be removed from the edge of the opening. In addition, only the capture pull-in mechanism main body T requiring maintenance can be detached from the guide rail 1 alone while leaving the guide roller 21 mounted on the guide rail 1 mounted on the fixed member side. . Therefore, unlike the conventional case, it is not necessary to remove the entire capture / retraction mechanism 20 from the guide rail 1, and maintenance of the capture / retraction mechanism 20 can be performed easily and in a short time. In particular, the present apparatus in which the sliding door 2 is retracted on both the closed side and the open side is useful because the frequency of maintenance is increased compared to the apparatus that is retracted only on one side.

  In addition, since the front guide roller portion 310 including the front guide roller 21 and the capture pull-in mechanism main body portion T are attached by a detachable attachment screw 213 inserted from a direction different from the moving direction of the sliding door 2, Front side against the urging force of the tension spring 226 that receives momentum (impact) when the sliding door 2 is opened and closed, and is forced to move the sliding door 2 to an open state or a closed state provided inside the capture pull-in mechanism main body T The guide roller part 310 side can be firmly fixed.

  Furthermore, since the rear guide roller portion 400 including the rear guide roller 21 and the capture pull-in mechanism main body portion T are detachably attached along the moving direction of the sliding door 2, the sliding door 2 can be opened and closed. The attachment of the rear guide roller portion 400 where the impact and the urging force of the tension spring 226 do not act can be structured to be easily pulled out in the moving direction of the sliding door 2.

  Moreover, since the rear guide roller part 400 provided with the guide roller 21 and the capture pull-in mechanism main body part T are attached by fitting, attachment / detachment can be facilitated. Therefore, the structure can be pulled out more easily.

  Furthermore, the capture pull-in mechanism main body T is configured to rotate around the other guide roller 21 with either one of the front or rear guide rollers 21 removed. The main body T can be rotated by its own weight to a position where it can be easily pulled out, and maintenance work can be performed more easily.

  On the other hand, according to the attachment / detachment method of the opening / closing body shock absorber according to the embodiment of the present invention, the front and rear guide rollers in the state where the capture pull-in mechanism 20 is attached to the guide rail 1 via the guide rollers 21. Since the capture pull-in mechanism main body T is removed while leaving 21 on the guide rail 1, the guide rail 1 attached to the upper edge or lower edge of the opening of the building is attached to the edge of the opening. From the guide rail 1, only the capture pull-in mechanism main body T that requires maintenance is removed from the guide rail 1 while leaving the guide roller 21 mounted on the guide rail 1 on the fixed member side. Can be removed alone. Therefore, unlike the conventional case, it is not necessary to remove the entire capture / retraction mechanism 20 from the guide rail 1, and maintenance of the capture / retraction mechanism 20 can be performed easily and in a short time. In particular, the present apparatus in which the sliding door 2 is retracted on both the closed side and the open side is useful because the frequency of maintenance is increased compared to the apparatus that is retracted only on one side.

  The catching / retracting mechanism 20 is attached by a detachable attachment screw 213 in which either the front or rear guide roller 21 and the catching / retracting mechanism main body T are inserted from a direction different from the moving direction of the sliding door 2. The other guide roller 21 and the catching / retracting mechanism main body T are fitted and attached so as to be detachable along the moving direction of the sliding door 2, and the catching / retracting mechanism 20 is attached to the guide rail 1 via the guide roller 21. In the attached state, the mounting screw 213 for fixing the capture / retraction mechanism body T is removed from either the front or rear guide roller 21 of the capture / retraction mechanism body T, and the other guide roller 21 is the center. The capture pull-in mechanism main body T is rotated, and the capture pull-in mechanism main body T is moved to the other guide line at a position where it can be easily pulled out. Since the so withdrawn from 21, it is possible removably to pivot by its own weight to easily position pull the capture retraction mechanism body portion T, good workability. Therefore, maintenance work can be performed more easily.

The opening / closing body shock absorber and the opening / closing body shock absorber attachment / detachment method according to the embodiment of the present invention have been described above, but the present invention is not limited to the above-described embodiment, and is based on the technical idea of the present invention. Various modifications and changes are possible.
For example, although the sliding door 2 is described in the present embodiment, the present invention is not limited to this. For example, even when a drawer or a double door is opened and closed, the present invention can be used as long as it is a device that urges the door to be forcibly closed.

  In the present embodiment, the guide roller 1 and the capture pull-in mechanism 20 are provided at the upper edge of the opening that is closed by the sliding door 2, but are provided at the lower edge of the opening instead of the upper edge. Even if it exists, this invention can be utilized. Even in this case, only the main body portion T of the capture pull-in mechanism 20 attached to the guide rail can be easily removed without removing the guide roller 21 from the guide rail 1. Thereby, the maintainability of the capture pull-in mechanism main body T can be improved.

  Furthermore, in the present embodiment, the front guide roller portion 310 side is fixed by the mounting screw 213 and the rear guide roller portion 400 is configured to be pulled out by fitting. However, an opposite structure may be used. That is, in the present embodiment, the suspension part 300 for supporting the sliding door 2 is provided on the front guide roller part 310 side, and the spring force for forcibly biasing the sliding door 2 to the closed state is the front guide rail part. 310 also has a structure in which the mounting screw 210 to be inserted in a direction different from the moving direction of the sliding door 2 is provided in the front guide roller unit 310, but the suspension unit 300 is provided in the rear guide roller unit 400. When providing, it is necessary to make it a reverse structure. Thus, the mounting structure can be reversed in the front and rear as appropriate depending on the position where the hanging part 300 is provided.
