Description

Switch body shock absorber {DAMPING DEVICE OF OPENING AND CLOSING DOOR}

The present invention relates to an opening and closing body shock absorber that can open and close the opening and closing bodies such as sliding doors and drawers forcibly gently at the time of opening, while being forcibly closed at the closing.

The conventional switchgear shock absorber is mounted on, for example, a sliding door rail on the building side, and is mounted on two sliding members disposed on both the open side and the closed side of the sliding door rail, and on the sliding side. And a capturing and retracting mechanism for capturing the member to be caught and for pulling the sliding door in the open direction or the close direction. The capturing entry mechanism is a longitudinal direction of the sliding door rail, which extends in the opening and closing direction of the sliding door, and at each end of the opening side and the closing side, the shaft is rotatable about a rotational shaft. A supported capture member (hook) is provided.

The capturing members on the open side and on the close side are slidably moved in the opening and closing direction, respectively, in the capturing insertion mechanism. Further, the catching members on the open side and the close side are connected in the opening and closing direction by a spring, and are pulled together by the spring force of the spring.

In addition, the capturing member on the open side and the close side is connected in the opening and closing direction by a damper for buffering the spring force pulling each other.

The capturing member on the closing side is for capturing the capturing member on the closing side. In this pre-captured state (captured release state), the capturing member on the closed side is locked (locked) to the main body portion (casing) of the capturing insertion mechanism, so that it cannot move in the opening and closing direction. From this locked state, when the sliding door is closed to a predetermined position, the captured member on the closing side and the capturing member on the closing side abut, and the capturing member is rotated. At this time, the lock between the capturing member and the main body is released to enable the capturing member to move in the opening and closing direction, and the capturing member on the closing side captures the capturing member on the closing side.

On the other hand, the capture member on the open side is for capturing the captured member on the open side. The capturing member and the capturing member on the open side have the same configuration as the closing side, and when the sliding door is opened to a predetermined position, the capturing member on the open side is rotated, the lock is released, and the capturing member can move in the opening and closing direction. In addition, the capture member on the open side captures the captured member on the open side.

In the opening and closing body shock absorber having such a configuration, when the sliding door does not reach any predetermined position on the closing side and the opening side, either of the capturing members in the state where the capturing members on the opening side and the closing side do not capture any captured member. The member is also locked to the main body of the capturing insertion mechanism so that neither capturing member can move in the opening and closing direction.

On the other hand, when the sliding door is closed to a predetermined position on the closing side and the capturing member on the closing side picks up the captured member, the locking of the capturing member on the closing side is released, but the capturing member on the open side is the main body of the capturing retracting mechanism. Locked, the captured member on the closed side is pulled to the open side by the pushing force of the spring. As a result, the sliding door is forcibly moved in the closing direction at the time of its closing.

On the contrary, when the sliding door is opened to a predetermined position on the open side and the capture member on the open side has captured the captured member, the lock on the capture member on the open side is released, but the capture member on the closed side is the main body of the capture retracting mechanism. Locked, the captured member on the opened side is attracted to the closed side by the pushing force of the spring. As a result, the sliding door is forcibly moved in the opening direction at the time of its opening.

In addition, when the sliding door is opened or closed, the damper described above buffers the pushing force of the spring, so that the sliding door is opened and closed smoothly (see Patent Document 1, for example).

Japanese Patent Publication No. 2009-127293

In the above-mentioned opening and closing body shock absorber, when the sliding door runs on the sliding door rail, the capturing member on either the closing side or the open side captures or releases the captured member. The capturing or releasing operation is performed by bringing the capturing member into contact with the capturing member and engaging or releasing the capturing member while the capturing member rotates. That is, the capturing member and the capturing member receive the opening / closing force of the sliding door at the predetermined position as it is, and rotate by the opening / closing force to forcibly engage or decouple the capturing member. In addition, the speed at which the capturing member rotates is almost the same as the speed at which the sliding door is opened and closed at this predetermined position.

Therefore, when trying to open and close the sliding door vigorously, when engaging or releasing the sliding door, the capturing member rotates at a high speed, and the capturing member and the capturing member strongly contact each other. Therefore, a big shock occurs at the time of engagement or decoupling. This shock causes the entire trapping mechanism to vibrate. For example, a vibration caused by the capturing operation on the open side is transmitted to the capturing member on the closing side, and a malfunction such as the locking of the capturing member on the closing side swings out. It happened.

On the contrary, the vibration by the capturing action on the closing side sometimes induced the malfunction of the capturing member on the open side.

In addition, when the sliding door is opened and closed vigorously, the speed at which the damper is elongated may be faster than the speed at which the spring draws the capture member. In this case, the spring cannot follow the opening / closing speed of the sliding door and thus cannot exert the pushing force (tensile force). Therefore, there is a possibility that the capturing member locked by the spring force rotates at its own weight and the capturing operation is released during the pulling operation.

In addition, when trying to open and close the sliding door vigorously, the capturing member rotates at a high speed, and the capturing member and the capturing member are forcibly engaged or decoupled, resulting in a coupling sound or a decoupling sound. Such sounds may be heard as annoying sounds, especially in the living room of a quiet home.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object thereof is to provide an opening / closing shock absorber which can reduce vibration caused by the capturing operation between the captured member and the capturing member, and further reduce the coupling sound or the decoupling sound. It is to provide.

MEANS TO SOLVE THE PROBLEM In order to solve the above-mentioned subject, this invention is a trapped member provided in each of the opening side and the closing side of any one of the opening | closing body or the fixing member which can guide the said opening-and-closing movement, and among the said fixing member or the said opening-closing body. And a trapping and retracting mechanism, which is attached to any one and configured to be movable in the opening and closing direction, wherein the capturing and retracting mechanism is configured to be movable in the opening and closing direction when the captured member on the closing side is captured and is not captured. When the first catch portion in which the movement in the opening and closing direction is locked and the capturing member on the open side is captured, the movable member is configured to be movable in the opening and closing direction. The second catch portion that is locked, the first catch portion and the second catch portion are connected in the opening and closing direction, so that the first catch portion When the first catching part is captured, the first catching part is led to the second catching part side, and when the second catching part catches the captured member on the open side, the second catching part is brought to the first catching part side. An opening and closing body shock absorber having a first elastic body to be introduced and a buffer member for cushioning a force for the first elastic body to enter the first catch portion or the second catch portion, the first catch portion and the second catch The contacting member is pressed against the captured member by the capturing member for capturing the capturing member and the opening / closing force for moving the opening and closing member along the fixing member to linearly move the capturing member so that the capturing member is moved. Each having a contact block for capturing and configured to move in the direction in which the contact block is pressed against the captured member when the captured member is captured. That is characterized.

According to this structure, even if the opening / closing body is opened and closed vigorously, the contact block moves and the impact at the first catch portion (or the second catch portion) is suppressed small.

The captured member may be attached to the fixing member, and the capture and pulling mechanism may be attached to the opening and closing body.

According to this structure, the capture | acquisition insertion mechanism can be comprised in the side which is easy to mount according to the structure of a switching body.

The capturing member is moved at a speed slower than the speed at which the opening and closing body is opened and closed.

According to this structure, it can depress the momentum which a capture member moves, and can move a capture member slowly.

The capturing insertion mechanism may further include a link mechanism for linearly sliding the capturing member and the abutment block in accordance with the opening and closing force for moving the opening and closing body along the fixing member.

According to this structure, a to-be-acquired member is captured as a slide moves, without rotating a capture | acquisition member.

In addition, the link mechanism has a link pin mounted to the capturing member, and a guide block through which the link pin is inserted, and an inner block for moving the capturing member up and down along the guide hole. And the abutment block, wherein the abutment block is formed with an inclined hole through which the link pin is inserted, and when the pressing member is pressed by the captured member, the capturing member moves in the up and down direction along the inclined hole. In addition, the contact block may be moved forward and backward with respect to the containment block.

According to this configuration, the contact block moves back and forth while the capture member moves up and down by the link mechanism.

Further, the link mechanism may be provided with a second elastic body that is arranged in the opening and closing direction between the inner block and the abutting block.

According to this structure, the movement of the contact block which the 2nd elastic body moves to the front-back direction is buffered, and the return operation | movement is promoted.

The capture insertion mechanism may further include a lock mechanism that holds the pushing force of the first elastic body when the capture member is slid and moved to release the capture member.

According to this structure, the capture member of the other side can be led in to the capture member side of the one side.

The locking mechanism may be operated by moving the capturing member in the vertical direction.

According to this configuration, the locking mechanism can be simply configured by using the vertical movement of the capture member.

In the opening and closing body shock absorber according to the present invention, the first catching portion and the second catching portion are caught by the catching member for catching the captured member, and by the opening and closing force for moving the opening and closing member along the fixing member. Each contact block has a contact block for linearly moving the capturing member to catch the capturing member by being pressed against the member, and the contact block is pressed against the capturing member when capturing the capturing member. Since it is comprised so that it may move to a direction, even if an opening / closing body is opened and closed vigorously, the contact block will move and the impact in a 1st catch part (or 2nd catch part) will be suppressed small. Therefore, in the 2nd catch part (or 1st catch part) to which the vibration by a capture operation is transmitted, the transmitted vibration can be made small. Therefore, in the second catch portion (or first catch portion) to which the vibration is transmitted, it is possible to prevent the malfunction caused by the vibration.

Moreover, when the sliding door is opened and closed vigorously, even if the damper extends faster than the speed at which the first elastic body pulls in the capturing member, the contact block is captured even if the pushing force of the first elastic body cannot be exerted. The capturing operation is not released as long as it is pressed by the member and moved in this pressing direction. Therefore, such a malfunction does not occur during the capturing operation, and a highly reliable opening and closing body shock absorber can be provided.

In addition, even when the opening and closing body is opened and closed vigorously, the contact block moves and buffers the force of contact with the member, thereby suppressing the coupling sound (collision) when the contact block and the member are contacted at the time of capture, The sound can be made smaller.

Further, since the capturing member is moved at a speed slower than the speed at which the opening and closing body is opened and closed, the capturing member can be depressed to move the capturing member to move slowly. As a result, when the capturing member moves to the upper limit at the time of capturing, the collision sound between the link pin and the upper end of the guide hole can be suppressed and the operation sound can be made smaller.

A corresponding perspective view.

In addition, "front side (front direction)" used by the following description shall mean the left side (door closing side) of FIG. 1, and "rear side (rear direction)" means the right side of FIG. We shall say (door open side). In addition, the direction of "up-down, left-right" shall mean the direction when the front side sees the switching body shock absorber 10 of FIG.

In addition, the "closed time" used in this specification means until the sliding door moves from the position which catches the to-be-acquired member 11 of the closing side to a position where the sliding door is completely closed. On the contrary, "opening time" shall mean until the sliding door fully opens from the position which the opening-closing body shock absorber 10 captures the to-be-acquired member 11 of the opening side.

The sliding device shown in FIGS. 1-3 is the guide rail 1 extended in the front-back direction (opening-closing direction) along the upper edge part of the opening part of a building, and along this guide rail 1 in the front-back direction. Sliding door 2 (opening and closing body) which opens and closes an opening by moving, and opening / closing buffer which guides this sliding door 2 to an open position or a closed position while braking when the sliding door 2 is opened or closed. It consists of the apparatus 10.

The opening and closing body shock absorber 10 includes the capturing member 11 on the closing side disposed on the front side of the guide rail 1, the capturing member 11 on the opening side disposed on the rear side of the guide rail 1, The guide rail 1 is constituted by a capture insertion mechanism 20 that can travel along the front-rear direction.

As shown in FIG. 1, the two to-be-acquired members 11 are formed in the concave shape which has the protrusion part 11a which protrudes toward the lower side. Such a member 11 is attached to a predetermined position (position for guiding the sliding door 2 in the opening and closing direction) on the front side and the rear side in accordance with the structure of the trapping mechanism 20.

The capture insertion mechanism 20 is housed inside the guide rail 1 having a cross-sectional c-shape in which the lower side is opened, and is mounted to be movable along the front and rear directions of the guide rail 1. More specifically, the capture insertion mechanism 20 is provided with guide rollers 21 (four in the front side and two in the rear side) in each of the front side part and the rear side part thereof. The guide roller 21 is driven on the raceway 1a of the guide rail 1, so that the capture insertion mechanism 20 can move freely in the front-rear direction of the guide rail 1.

In addition, the front part of the capture | acquisition drawing-in mechanism 20 is provided with the suspension part 300 mentioned later for details. The hanging part 300 is equipped with the upper end part of the sliding door 2 (the upper part obliquely to the left side of the page in Fig. 1), and the front end of the sliding door 2 is mounted. It is supported in the form of hanging parts. As a result, when the sliding door 2 is moved in the opening and closing direction (front and rear direction), the guide roller 21 of the capture insertion mechanism 20 rolls on the guide rail 1, and the sliding door 2 is moved forward and backward. Open and close smoothly.

In addition, although not the capture | acquisition insertion mechanism 20, the suspension part 5 is attached also to the upper-angle corner part of the right side of the sliding door 2. As shown in FIG. The hanging portion 5 supports the rear end portion of the sliding door 2 in the form of hanging, and the sliding door 2 is a guide roller 21 which can roll the driving surface 1a of the guide rail 1. ), The opening and closing smoothly in the front and rear directions.

As shown in FIGS. 1-3 and 4-6, the capture | acquisition drawing-in mechanism 20 has the 1st catch part 100 located in the front side, and the 2nd catch part 150 located in the rear side. It is installed. The first catch portion 100 is capable of sliding in the front-rear direction inside the capture insertion mechanism 20, and captures the projection 11a of the front-side captured member 11 at a predetermined position at the time of closing. do. In addition, the second catch portion 150 is also capable of sliding in the front-rear direction inside the capturing insertion mechanism 20, so that the projection 11a of the rear-side captured member 11 is moved at a predetermined position at the time of opening. Acquisition (details of the capture operation will be described later).

As shown in FIG. 1, the capture | acquisition drawing-in mechanism 20 has the 1st catch part 100 and the 2nd catch part 150 in the state which the sliding door 2 is located in the middle of an opening-closing direction. It is located between the capture member (11). In this state, neither the first catch part 100 nor the second catch part 150 captures the projection part 11a of the to-be-collected member 11. In other words, in this state, the capture insertion mechanism 20 does not function (standby state). In this standby state, the first catch portion 100 is positioned on the front end side of the capture insertion mechanism 20 in a state of being locked (details will be described later) on the main body side of the capture insertion mechanism 20, and the second catch portion. 150 is also located at the rear end side of the capture insertion mechanism 20 in the locked state (see FIG. 4).

When the sliding door 2 is moved to the front side (the left side of the ground, the door closing side in Fig. 1) from this standby state, the locking of the catch portion 100 described above is released when the sliding door 2 is closed, 1 catch part 100 captures the to-be-acquired member 11 located in the front side (door closed state. See FIG. 2).

In this door closed state, as shown in FIG. 5, while the 1st catch part 100 catches the to-be-acquired member 11, the center part side by the force of the spring 226 (refer FIG. 7 and FIG. 8) is carried out. Move to (arrow A direction). That is, the capture insertion mechanism 20 acts to pull the captured member 11 to the sliding door 2 side (right side, rear side in FIG. 1). As a result, the sliding door 2 is forcibly moved in the relatively closing direction (left side, front side in FIG. 1), and as shown in FIG. 2, the sliding door 2 is engaged with the front door stop 3 of the front side. It will be completely closed until it is reached. Moreover, in this door closed state, the 2nd catch part 150 stays in the same position as a standby state in the locked state.

On the other hand, when the sliding door 2 is moved from the standby state to the rear side (the right side of the ground in Fig. 1, the door opening side), the catch portion 150 described above is opened when the sliding door 2 is completely opened. The lock is released, and the second catch portion 150 captures the trapping retracting member 11 positioned at the rear side (door open state. See FIG. 3).

In this door open state, as shown in FIG. 6, the 2nd catch part 150 moves to the center part side (arrow B direction) by the force of the spring 226, capturing the captured member 11 of a rear side. . That is, the capture insertion mechanism 20 acts to pull the captured member 11 to the sliding door 2 side (left side, front side in FIG. 1). As a result, the sliding door 2 is forcibly moved in a relatively open direction (right side and rear side in FIG. 1), and as shown in FIG. 3, the sliding door 2 is engaged with the rear door stopper 4. It opens completely until it reaches it. Moreover, in this door open state, the 1st catch part 100 stays in the same position as a standby state in the locked state.

7 is an exploded perspective view of the capture insertion mechanism 20 as viewed from above, and FIG. 8 is an exploded perspective view of the capture insertion mechanism 20 as viewed from below. 9 is an enlarged view of the state which disassembled the 1st catch part 100, (a) is an exploded perspective view seen from the right side obliquely upward, and (b) is an exploded perspective view seen from the bottom obliquely leftward. 10 is an exploded perspective view of the second catching part 150 viewed obliquely downward.

As shown in FIGS. 4-6, 7 and 8, the capture | acquisition drawing-in mechanism 20 has the 1st catch part 100 which captures the projection part 11a of the to-be-adhered member 11, and the back side The second catch portion 150 for capturing the member 11 and the catch portion 200 for introducing the catch portions 100 and 150 to the center side along the extending direction (front and rear direction) of the guide rail 1. ).

The 1st catch part 100 is comprised as a link mechanism which operates according to the position of the link pin 140 mentioned later. Specifically, the first catch portion 100 is located at a predetermined position with the protrusion 11a of the member 11 to be captured, as shown in Figs. 7 and 8, in particular, Figs. 9 (a) and 9 (b). The contact block 110 which abuts, the capture plate 120 which moves up and down in order to capture this protrusion part 11a, and this contact block 110 and the capture plate 120 are contained, and are moved back and forth in these whole. The first containment block 130 moving in the direction, and the contact block 110, the capture plate 120, and the first containment block 130 are constituted by a link pin 140 for operating as a link mechanism. .

The abutment block 110 is formed in the form of a main body portion 111 formed in a substantially rectangular parallelepiped shape and protrudes obliquely upwardly to the rear of the main body portion 111, and an upper portion thereof is larger than an upper surface of the main body portion 111. It consists of the support part 112 which protrudes upwards.

The main body 111 has a cavity inside thereof, and the cavity is formed so as to penetrate up and down. In this cavity, the capture plate 120 is inserted and assembled from the lower opening. Further, the main body portion 111 is formed with an inclined hole 111a that extends obliquely forward and obliquely downward from the upper side to the lower side. The inclined hole 111a is formed to penetrate in the left and right direction of the main body 111 so that the link pin 140 is inserted when the first catch portion 100 is assembled.

9 (a) and 9 (b), the contact surface 112a which stands up from the upper surface of the main-body part 111 is formed in the front surface of the base part 112. As shown in FIG. When the contact surface 112a reaches the predetermined position at the time when the sliding door 2 closes, it comes in contact with the projection part 11a of the to-be-acquired member 11, and is pressed.

Moreover, as shown to FIG. 9 (b), the spring accommodating groove 112b of the shape concave in the front-back direction is formed in the back surface of the support part 112. As shown in FIG. One end of the compression coil spring 113 is supported by this spring receiving groove 112b.

The capture plate 120 is formed in a substantially rectangular shape, and a capture protrusion 121 is formed to protrude upward from the upper surface thereof. This capture | acquisition protrusion 121 is the projection part 11a of the to-be-attached member 11 with the above-mentioned support part 112 and this capture | acquisition protrusion 121, when the capture | acquisition plate 120 moved upwards by the link mechanism. ) Is captured from front to back.

A taper abutting surface 121a is formed on the rear surface of the capturing protrusion 121. The taper contact surface 121a is an inclined surface that is inclined upwardly obliquely upward from the lower side of the taper. When moving the sliding door 2 from the closed state (refer FIG. 2) to the opening direction, the projection part 11a of the to-be-adhered member 11 abuts on this taper contact surface 121a. And the projection part 11a pushes down the capture | acquisition protrusion 121 obliquely downward to the front which is a direction perpendicular | vertical to this taper surface. Thereby, it releases from the state which captured the protrusion part 11a, and returns to a standby state from the door closed state.

In addition, the capture plate 120 is provided with an auxiliary projection 122 located at the front side of the capture protrusion 121. When the auxiliary projection 122 cannot capture the projection 11a by the capturing projection 121 and the supporting portion 112 described above, the projection 11a is formed between the projection projection 121 and the auxiliary projection 122. ), That is to say, installed auxiliary.

Even if the auxiliary protrusion 122 captures the member 11 with the catching protrusion 121 and the auxiliary protrusion 122, the opening and closing body buffer device 10 causes the sliding door 2 to be closed. It is supposed to be. More specifically, when the catching protrusion 122 is pressed forward by the protrusion 11a of the captured member 11 when opening the sliding door 2, the catching protrusion 122 is bent downward and avoided. The capture member 11 is retracted to the front side of the auxiliary protrusion 122.

In addition, the capture plate 120 is provided with mounting holes 123 located below the capture protrusion 121 and penetrating in the left and right directions. The mounting hole 123 is a round hole having a diameter equal to or slightly larger than the outer diameter of the link pin 140, and a link pin 140 to be described later is inserted into the mounting hole 123. As a result, the capture plate 120 moves together with the link pin 140 in accordance with the movement of the link pin 140.

As shown in Figs. 7 and 8, in particular, Figs. 9A and 9B, the first nesting block 130 has an outer portion 131 formed in a substantially rectangular parallelepiped shape, and It consists of the support part 132 which protrudes from the rear end to the back side, and the guide protrusions 133 and 134 which protrude toward the outside of left and right from the left and right both sides of the outer part 131, respectively.

The outer portion 131 has a cavity inside thereof. This cavity is formed in the form of penetrating up and down. In this cavity, the contact block 110 is inserted and assembled from the upper opening. In addition, the outer portion 131 is formed with guide holes 131a extending in the vertical direction when viewed from the front. The guide hole 131a is formed to penetrate in the left and right direction of the outer portion 131, and when the first catch portion 100 is assembled, the inclined hole 111a of the contact block 110 is captured. The link pin 140 is inserted through the mounting hole 123 of the plate 120.

Moreover, the support surface 131b which stands up and down is formed in the rear end part in the cavity of the outer part 131. As shown in FIG. The other end of the compression coil spring 113 is supported on the support surface 131b in a state where the abutment block 110 is assembled in the first inner containment block 130.

Next, the operation of the opening and closing body shock absorber according to the embodiment of the present invention and the operation of the link mechanism functioning by the link pin 140 will be described. Fig. 13A is a plan view of the trapping mechanism, Fig. 13B is a front view of the trapping mechanism, and Fig. 14 is a sectional view taken along line C-C in Fig. 12A. 15 is a figure explaining the operation | movement of a 2nd catch part, (a) is an enlarged front view of a rear part, (b) is X-X sectional drawing. 16 is a figure explaining the operation | movement of a 2nd catch part, (a) is an enlarged front view of a rear part, (b) is Y-Y sectional drawing. 17 is a figure explaining the operation | movement of a 2nd catch part, (a) is an enlarged front view of a rear part, (b) is Z-Z sectional drawing. 18 is sectional drawing of a 2nd catch part, (a) is a figure which shows the state before a capture | acquisition member capture | acquires a to-be-captured member, and (b) shows a state after a capture | acquisition.

Here, the operation of the first catching part 100 and the second catching part 150, and the operation of the link mechanism are opposite to each other in the front-back direction, and the operation is the same. Therefore, in the following description, the operation | movement of the link mechanism in the 2nd catch part 150 is demonstrated, and the description about the link mechanism of the 1st catch part 100 is abbreviate | omitted.

In the standby state (see FIGS. 1, 4, 13 (a), 13 (b) and 14) in which the second catching part 150 does not capture the captured member 11, the link mechanism is operated. The link pin 140 is located at the position of the projection part ablation hole 219 which cut | disconnected the projection part 218 in the front-back direction. In addition, the end 140a of the link pin 140 is positioned below the upper surface of the protrusion 218 through the cutout 262. At this time, as shown in Figs. 15A and 15B, the capture plate 120 of the second catch portion 150 is in a downward state, and the lower portion of the capture plate 120 is guided ( It protrudes downward from the bottom square hole 217 of 210.

In addition, in this state, as shown to FIG. 15 (a) and FIG. 18 (a), the edge part 140a of the link pin 140 is cut | disconnected of the notch 262 formed by the protrusion part hole 219. As shown to FIG. It is in contact with the cotton in the front and rear direction. As a result, the second catch portion 150 is locked so that it cannot move freely in the front-rear direction.

When the sliding door 2 is moved to the door opening side (rear side. H direction of FIG. 18 (a)) from this waiting state, as shown to FIG. 16 (a) and FIG. 18 (b), the to-be-adhered member The projection 11a of 11 contacts the contact surface 112a of the contact block 110 of the 2nd catch part 150, and presses the contact block 110 forward. This pressing force E is equal to the force to open the sliding door 2, and a large force acts when it tries to open forcefully.

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

When the abutment block 110 slides forward, the inclined hole 111a of the abutment block 110 shown in FIG. 15 (a) moves forward as shown in FIG. 16 (a). The pin 140 is pushed up in the upper direction F along the inclination hole 111a and the guide hole 161a of the second inner block 160. As a result, the capture plate 120 moves upward with the link pin 140. In this state, as shown in Figs. 16A and 18B, the protrusions 11a of the rear-side captured member 11 are supported by the supporting portions 112 of the abutment block 110 described above. It is captured in the form of sandwiching the front and rear from the capture projection 121 of the capture plate 120.

In addition, when the link pin 140 moves in the upper F direction, as shown in FIG. 16B, the link pin 140 is located above the upper surface of the protrusion 218, and therefore, the notched surface of the cutout portion 262 of the protrusion 218. The locked state is released. As a result, the lock of the second catching part 150 is released, so that the end 140a of the link pin 140 can slide freely in the front-rear direction while sliding the upper surface of the protrusion 218.

In addition, when the speed of the upward movement of the capture plate 120 is based on the length of the inclined hole 111a, since the length of the guide hole 131a is short, it can be made slower than the speed of the contact block 110. have. That is, the capture plate 120 is moved upward at a speed slower than the speed of opening and closing the sliding door 2 (moving speed of the contact block 110).

In the unlocked state, as shown in Fig. 17A, the second catch portion 150 is pulled by the tension spring force of the tension spring unit 225 to the first catch portion 100 side (front side. G). Direction). In more detail, when the 2nd catch part 150 catches the protrusion part 11a in the fixed position of the to-be-acquired member 11, the operation | movement is completed, and the tension spring unit 225 and the damper thereafter. Unit 221 is operated.

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 mounting position of the captured member 11 while capturing the captured member 11, and the entirety of the capturing lead mechanism 20 other than the second catch portion 150 remains in place. Moves relatively backwards. That is, the tension spring force of this tension spring unit 225 pushes the sliding door 2 in the forcibly opening direction. As a result, the sliding door 2 is guided to the state where the sliding door 2 is completely opened, as shown in FIG. 3.

In addition, in the above-mentioned moving state, 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 forcefully.

On the contrary, when the sliding door 2 is moved from the completely open state to the closing direction (moving the sliding door 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 projection part 11a of the captured member 11 of the rear side contacts the capture | acquisition protrusion 121 of the capture plate 120, and the 2nd catch part 150 The tension spring 226 of the tension spring unit 225 moves in the direction of guiding. At this time, since the projection part 11a presses the taper contact surface 121a of the capture | acquisition protrusion 121, it always presses down to the capture plate 120 during the movement of the 2nd catch part 150 to the front-back direction. Force is at work The pushing force is supported 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 reaches the position of the protrusion 218. The pin 140 is pushed down through the cutout 262 of the protrusion 218.

In addition, since the end 140a of the link pin 140 is squeezed onto the protrusion 218 when the above-described downward force is acting, vibration hardly occurs during the movement of the second catch 150. . Therefore, the vibration transmitted to the 1st catch part 100 can be suppressed small by the movement of the 2nd catch part 150, and malfunctions, such as the lock of the 1st catch part 100, are hard to arise. Lose.

As a result, the capture plate 120 moves downward from the position of the projection cutout hole 219 (cutout portion 262), whereby the captured state is released. In addition, the end 140a of the link pin 140 is locked in the front-rear direction by contacting the cut-out surface of the cutout portion 262, so that the second catch portion 150 cannot freely move in the front-rear direction.

In addition, the contact block 110 is accelerated (assisted) by the force of the compression coil spring 113 to push back. As a result, the movement of the link mechanism at the time of capture release is performed more smoothly.

According to the opening and closing body shock absorber which concerns on embodiment of this invention, the to-be-adhered member 11 provided in each of the opening side and the closing side of the guide rail 1 which guides the sliding door 2 so that a movement is possible, and the sliding door (2) is provided with a capture insertion mechanism (20) configured to be movable on the guide rail (1) in the opening and closing direction, and the capture insertion mechanism (20) has captured the captured member (11) on the closed side. It is configured to be movable in the opening and closing direction at the time, and moves in the opening and closing direction when the first catch part 100 and the captured member 11 on the open side are locked when the movement in the opening and closing direction is locked when not being captured. It is comprised so that the 2nd catch part 150 and the 1st catch part 100 and the 2nd catch part 150 which lock the movement to an opening-closing direction when it is not capturing can be connected, 1 when the catch 100 catches the capturing member 11 on the closed side When the first catch part 100 is led to the second catch part 150 side and the second catch part 150 catches the captured member 11 on the open side, the second catch part 150 is held. The tension spring 226 which draws into the 1st catch part 100 side, and the damper unit 221 which buffers the force which the tension spring 226 enters the 1st catch part 100 or the 2nd catch part 150. (1), the first catching part (100) and the second catching part (150) are a catching plate (120) (capturing member) for capturing the member (11), and a sliding door ( Abutting block for contacting the captured member 11 by the opening and closing force for moving the 2) along the guide rail 1 to press the captured member 11 to linearly move the capturing member 11 to capture the captured member 11; Each of the holding doors 110 is configured to move in the direction in which the contact block 110 is pressed against the captured member 11 when the captured member 11 is captured. Even if it opens and closes, the contact block 110 moves, and the impact at the time of the contact by the 1st catch part 100 (or the 2nd catch part 150) is suppressed small. Therefore, the transmitted vibration can be made small by the 2nd catch part 150 (or 1st catch part 100) to which the vibration by a capture operation is transmitted. Therefore, the second catch portion 150 (or the first catch portion 100) through which the vibration is transmitted can prevent the malfunction caused by the vibration from occurring.

In addition, when the sliding door 2 is opened and closed vigorously, the damper unit 221 extends faster than the speed at which the tension spring 226 pulls in the capture plate 120, so that the tension spring 226 is pushed. Even if the force cannot be exerted, the capturing operation is not released as long as the abutting block 110 is pressed against the captured member 11 and moved in the pressing direction. Therefore, such a malfunction does not occur during the capturing operation, and a highly reliable opening and closing body shock absorber can be provided.

In addition, even if the sliding door 2 is opened and closed vigorously, the contact block 110 is moved to buffer the force of contact with the captured member 11, so that the contact block 110 and the captured member 11 at the time of capture. The coupling sound (collision sound) at the time of contact can be suppressed, and the coupling sound can be made smaller.

In addition, since the capture plate 120 is moved at a slower speed than the speed at which the sliding door 2 is opened and closed, the capture plate 120 can be moved to decelerate the moving plate to slowly move the capture plate 120. have. This suppresses the collision sound between the link pin 140 and the upper end of the guide hole 131a or the inclined hole 111a when the capture plate 120 moves to the upper limit at the time of capturing, thereby making the operation sound smaller. Can be.

In addition, the capture insertion mechanism 20 is provided with a link mechanism for linearly sliding the capture plate 120 and the contact block 110 by the opening and closing force for moving the sliding door 2 along the guide rail (1). Since the capture plate 120 is rotated, the captured member 11 is captured while the slide plate moves. Therefore, compared with the structure which engages or disengages by a rotation operation | movement, it does not apply an excessive force and it operates smoothly, and it can reduce the vibration at the time of capture and a coupling sound.

In addition, the link mechanism has a link pin 140 mounted on the capture plate 120 and a guide hole 131a through which the link pin 140 is inserted, and moves up and down the capture plate 120 along the guide hole 131a. And an inclination hole 111a through which the link pin 140 is inserted, the first and second nesting blocks 130 and 160 and the abutment block 110 to move to the abutment block 110. Is formed, and when it is pressed by the to-be-acquired member 11, while moving the capture | acquisition plate 120 to an up-down direction along the inclined hole 111a, the contact block 110 along the inclined hole 111a is made | formed Since the first and second nested blocks 130 and 160 are moved in the front-rear direction, the contact block 110 moves back and forth while the capture plate 120 moves up and down by the link mechanism. As a result, the link mechanism can be configured with a simple and easy structure.

Moreover, since the link mechanism is provided with the compression coil spring 113 (2nd elastic body) extended in the opening-and-closing direction between the 1st and 2nd containment blocks 130 and 160 and the contacting block 110, 2 The elastic body buffers the movement of the contact block which moves in the front-back direction, and promotes the return operation at the time of capture release. Therefore, the opening and closing force of the sliding door 2 can be buffered, and the return operation | movement which the capture plate 120 moves below can be assisted.

In addition, since the capture insertion mechanism 20 includes a lock mechanism that holds the pushing force of the tension spring 226 when the capture plate 120 is slid and moved to release the capture plate 120, the first catch portion (1) on one side ( The second catch portion 150 (or the first catch portion 100) on the other side may be introduced into the 100 (or second catch portion 150) side. Therefore, the tension springs 226 are attracted to each other, whereby the number of parts can be reduced.

In addition, since the lock mechanism is operated by moving the capture plate 120 in the vertical direction, the lock mechanism can be simply configured by using the vertical movement of the capture plate 120. In addition, since it moves linearly instead of rotating, the locking operation can be performed smoothly, and the vibration and sound at the time of engagement or disengagement can be reduced as compared with the rotating structure.

As mentioned above, although the switching body shock absorber which concerns on embodiment of this invention was described, this invention is not limited to embodiment which was demonstrated previously, Various deformation | transformation and a change are possible based on the technical idea of this invention.

For example, although the sliding door 2 is described in this embodiment, it is not limited to this. For example, the present invention can be used as long as the device is pushed in the direction of forcibly closing the door even when opening or closing a drawer, a left or right door or the like.

In addition, in this embodiment, although the switching body shock absorber 10 is provided in the upper part of a sliding door, it can also be provided in the lower part. That is, even when the guide rail 1 is attached to the lower edge of the opening portion, the opening and closing body shock absorber 20 according to the present invention may be mounted on the lower portion thereof.

In addition, in this embodiment, although the tension spring 226 and the compression coil spring 113 were described as a spring which is an elastic body, it is not limited to a spring. That is, it can be used for the present invention as long as it causes a pushing force by elasticity.

In addition, in this embodiment, although the to-be-attached member 11 is attached to the guide rail 1 side, and the capture | acquisition insertion mechanism 20 is attached to the sliding door 2 side, it may be reversed. According to this structure, the capture | acquisition insertion mechanism 20 can be comprised in the side which is easy to mount according to the structure of the sliding door 2, and design freedom is extended.
