  Incidentally, since the door closer described in Patent Document 1 is provided with an air damper that cushions the moving force of the slide member, when the slide member and the receiving member are reengaged, the holding state of the slide member is released. However, the slide member is braked by the air damper. In this way, when the braking force is applied in the middle of opening / closing the sliding door, the sliding direction end of the sliding door may jump up. In other words, the sliding door is usually assembled with a little play with respect to the door frame, and based on this play, the end of the sliding door in the sliding direction may jump up when the catch body and the hook body come into contact with each other during braking. there were.

  Here, a member that fills the gap between the sliding door and the door frame may be interposed to suppress the flip-up, but there are various gaps, and the flip-up that fits into each of the gaps is wide. Providing a plurality of types of suppression members leads to an increase in cost. In addition, this flip-up suppressing member is attached to the door frame from the viewpoint of improving the appearance.For example, in the case of a slide assist device that assists sliding in the closing direction, the sliding door is slid in the closing direction to slide the sliding member and the receiving member. There is a problem that it is necessary to position the flip-up suppressing member above the end in the closing direction of the sliding door when the two are engaged, and the positioning is troublesome.

  The present invention has been made in view of the above-described conventional problems. When a braking force is applied to the sliding door, the sliding door can be easily and effectively suppressed from being flipped up due to the braking force. The object is to provide a flip-up suppressing device.

  In order to solve the above-described problems, a sliding door flip-up suppressing device according to the present invention is attached to a sliding door that opens and closes an opening of a structure, and guides the sliding door along a rail provided in the structure. A main body, a receiving member that is attached to the structure and engages with the guide main body to apply a braking force to the guide main body at an intermediate position of opening and closing of the sliding door, and is attached to one of the guide main body and the sliding door. A pressing means for advancing to the other side of the guide main body and the sliding door to press the member on the other side in accordance with the braking of the guide main body by the engagement with the receiving member.

  According to the present invention, the guide body includes a guide body and a receiving member, and is attached to one of the guide body and the sliding door, and any one of the guide body and the sliding door accompanying braking of the guide body by engagement with the receiving member. When the guide body is braked by the engagement between the guide body and the receiving member, the pressing means is attached to the guide body. Advances to the sliding door side and presses the sliding door (when the pressing means is attached to the sliding door, it advances to the guide body side and presses the guide body). An external force acts on the sliding door in a direction to suppress the flipping up by the pressing by the pressing means, and thereby the sliding door can be easily and effectively suppressed from jumping up. In addition, the guide body or sliding door that slides when opening and closing is provided with a pressing means, and the other member that similarly slides is pressed by this pressing means, so that it is more stable than when pressing a stationary member. The sliding door can be smoothly prevented from jumping up.

  The specific configuration of the pressing means is not particularly limited, and when the guide member and the receiving member are engaged, the electric actuator or the like advances from the guide main body side to the sliding door side (or vice versa). It may also be one that presses the sliding door (or the guide body) by utilizing the biasing force by the elastic member, etc., but the pressing means includes a pressing block provided on the guide body, It is preferable to include a block advance mechanism that advances the pressing block from the guide body and presses the sliding door with the braking of the guide body.

  If comprised in this way, a press block can be easily advanced by a block advance mechanism using the braking of a guide main body, and the raising of a sliding door can be suppressed easily and reliably.

  In this case, the specific configuration of the pressing block and the block advancement mechanism is not particularly limited, but it is preferable that the pressing means has a conversion mechanism that converts a part of the sliding movement force of the sliding door into the advance output of the pressing block. . For example, the pressing block includes an inclined guide hole that penetrates in the width direction and inclines in the vertical direction with respect to the sliding direction of the sliding door, and the block advancing mechanism is connected to the guide body and moves the pressing block up and down. A base body that can be held, and a guide boss that is connected to the base body so as to be movable in the sliding direction of the sliding door, and is connected to the sliding door and is movably inserted into the inclined guide hole of the pressing block. An auxiliary guide body having a portion, and with the braking of the guide body, the auxiliary guide body moves away from the base body and the guide boss portion moves relatively along the inclined guide hole. It is preferable that the pressing block is configured to advance to the sliding door side.

  If comprised in this way, while a sliding door will slid and a braking force will act on a guide main body, a base body and an auxiliary | assistant guide body will move to a separation direction relatively along the sliding direction of a sliding door. Along with the movement in the separating direction, the guide boss portion of the auxiliary guide body moves in the inclined guide hole of the pressing block held by the base body, so that the pressing block advances from the base body to the sliding door side and Press the sliding door. Accordingly, the pressing force by the pressing block can be generated according to the braking force of the guide body with a simple structure, and this pressing force is generated according to the flip-up force of the sliding door (sliding sliding force of the sliding door). The sliding door can be effectively prevented from jumping up.

  Also in this invention, the specific configuration of the guide body is not particularly limited. For example, the guide body is a structural member of a sliding door braking device that cushions the sliding door by applying a braking force to the sliding door at the end of opening and closing. However, it may be a slide assist device (door closer) that applies sliding assist force of the sliding door at the end of opening and closing. Specifically, the guide body includes a frame, an elastic member that is housed in a free state in the frame, a slide member attached to the free end of the elastic member, and at least the slide member. A damper member that imparts a buffering effect to movement in a predetermined direction, and the sliding member and the receiving member engage with each other when the sliding door slides in one direction to extend the elastic member. The urging force of the elastic member is accumulated in the position, and when the slide member reaches a predetermined holding position, the engagement between the slide member and the receiving member is released, and the slide member is held in the holding position. When the sliding member and the receiving member are engaged with each other when the direction is slid, the urging force of the elastic member is released and the shock absorbing effect of the damper member The urging force braking force being applied is preferably applied to the sliding door as a slide assist force through the slide member.

  Thus, the flip-up restraining device for the sliding door of another invention can be preferably applied to the door closer.

  According to the sliding door flip-up suppressing device according to the present invention, when the guide body is braked by the engagement between the guide body and the receiving member, the pressing means advances from one member side and presses the other member, As a result, an external force can be applied to the sliding door in a direction to suppress the flipping up, and the sliding door can be easily and effectively prevented from jumping up. In addition, since both the member provided with the pressing means and the member pressed by the pressing means slide, it can be pressed more stably than when pressing the stationary member, and the sliding door can be smoothly bounced. Raising can be suppressed.

  Next, assembly of the pressing unit 6 will be described.

  First, the block main body 621 of the pressing block 62 is inserted into the holding hole 632 of the base body 63. Subsequently, the body portion of the base body 63 is inserted between the opposing wall portions 641 of the auxiliary guide body 64. At this time, the boss mounting hole 64a of the auxiliary guide body 64, the boss insertion hole 63a of the base body 63, and the inclined guide hole 62a of the pressing block 62 are aligned with each other in the front-rear direction. The guide boss portion 65 is inserted into each of the holes 64a, 63a, 62a. Since the guide boss portion 65 is press-fitted into the boss mounting hole 64 a of the auxiliary guide body 64, the guide boss portion 65 is fixed to the auxiliary guide body 64. Thereby, the assembly of the pressing unit 6 is completed.

  Then, the base unit 633 of the pressing unit 6 is attached to the frame body 311 and the guide attaching part 642 is attached to the first edge block 312 to attach the pressing unit 6 to the apparatus body 3.

  In this pressing unit 6, the base body 63 and the auxiliary guide body 64 are configured to be movable in the sliding direction of the sliding door D, and the guide boss portion 65 is moved from one end portion of the boss insertion hole 63a to the other end portion with this movement. Move to. As the guide boss 65 moves, the guide boss 65 moves in the inclined guide hole 62 a of the pressing block 62, so that the pressing block 62 moves forward and backward with respect to the base body 63.

  The operation of the slide assist device 1 configured as described above will be described with reference to FIGS. FIG. 6 is a partial sectional view in front view for explaining the operation of the slide assist device 1 when the sliding door D is opened from the closed state, and FIG. 7 is the same device when the sliding door D is closed from the opened state. It is a partial sectional view of the front view for demonstrating the effect | action of 1. FIG. FIG. 8 is a conceptual diagram for illustrating an initial state of the pressing unit 6, and FIG. 9 is a conceptual diagram for illustrating a sliding door pressing state of the pressing unit 6 when a braking force is applied to the apparatus main body 3.

  While explaining the action of the sliding assist force of the sliding door D, the action of suppressing the lifting of the sliding door D will also be explained.

  First, the function in the case of opening the sliding door D in the closed state will be described.

  As shown in FIG. 4, the sliding member 34 is in the initial position in the closed state of the sliding door D, and is located at the right end portion of the guide slit 311 a. In the closed state of the sliding door, as shown in FIG. 6A, the rotating engagement piece 342 of the slide member 34 is set to an engagement posture in which the tongue piece 342c protrudes upward from the frame body 31 through the guide slit 311a. Has been. In this engagement posture, the left end surface of the tongue piece 342c is engaged with the right side surface of the receiving projection 51 of the receiving member 5.

  When the sliding door D is moved leftward from this closed state and opened, the apparatus main body 3 also moves leftward along with the opening, but the tongue piece 342c is engaged with the receiving protrusion 51. Therefore, the movement of the slide member 34 is hindered. Therefore, the slide member 34 moves to the right relative to the frame body 31 along the guide slit 311a. As the slide member 34 moves, the tension spring 32 extends, and thereby the biasing force of the tension spring 32 is accumulated in the slide member 34.

  When the sliding door D is continuously opened, the sliding door D reaches a predetermined opening / closing position, and at this time, the tongue piece 342c of the slide member 34 reaches the rotation hole 311b. When the sliding door D is further opened from this state, the tongue piece 342c is pressed rightward by the receiving projection 51, and the tip protruding portion 342d of the tongue piece 342c engages with the right edge of the rotation hole 311b. The rotation engaging piece 342 rotates clockwise about the rotation shaft 342a. As a result, as shown in FIG. 6B, the rotation engaging piece 342 rotates through the rotation hole 311 b and changes its posture to the released posture in which the engagement state with the receiving projection 51 is released.

  At this time, the tongue piece 342c whose posture has been changed to the release posture is pulled to the left by the urging force of the tension spring 32, and the left end surface of the tongue piece 342c is locked to the left end edge of the rotation hole 311b (FIG. 7 ( A)). Accordingly, the slide member 34 is stopped and held at the holding position corresponding to the rotation hole 311b, and the front left end portion of the triangular block 342b of the rotation engagement piece 342 protrudes forward of the frame body 31 through the guide slit 311a. Placed in a state.

  Next, the function in the case of closing the sliding door D in an open state will be described.

  When the fully open sliding door D is moved to the right and closed, the sliding door D reaches the opening / closing position. At this time, as shown in FIG. 7A, the front left edge of the triangular block 342b interferes with the receiving projection 51, whereby the rotating engagement piece 342 rotates counterclockwise around the rotation shaft 342a. The tongue piece 342c moves out of the rotation hole 311b, and the state where the left corner portion of the tongue piece 342c is locked to the left edge portion of the rotation hole 311b is eliminated. That is, the rotation engaging piece 342 changes its posture from the release posture to the receiving protrusion 51 to the engagement posture (see FIG. 7B).

  As the posture is changed, the urging force of the pulling spring 32 is released and acts on the slide member 34. The slide member 34 is given a certain resistance by the damper member 33, and the frame 31 along the guide slit 311a. Relative to the holding position moves toward the initial position. At this time, since the slide member 34 is engaged with the receiving protrusion 51 of the receiving member 5, the urging force of the pulling spring 32 acts in the closing direction of the sliding door D as a slide assist force.

  By the way, in the closing operation of the sliding door D, when the closing speed of the sliding door D is high, the receiving projection 51 of the receiving member 5 interferes with the triangular block 342b and then collides with the protruding engaging portion 341b of the slide block 341. The braking force by the damper member 33 is applied to the apparatus main body 3, and the sliding door D is decelerated. In the conventional slide assist device 1, when this braking force is applied, the sliding door D is in a one-sided state, that is, the braking force is applied only to one upper end portion of the sliding door D and the braking force is not applied to the lower portion. Therefore, although the sliding door D may jump up, since the sliding assist device 1 of this embodiment is equipped with the sliding door flip-up suppressing device, the sliding door D can be effectively prevented from jumping up.

  That is, when the sliding door D is closed, a sliding force (specifically, a sliding operation force or an inertial force) acts on the sliding door D including the sliding door fixing body 2. At this time, when the receiving projection 51 of the receiving member 5 interferes with the protruding engaging portion 341 b of the slide member 34, the braking force by the damper member 33 acts on the apparatus body 3 as a braking force through the slide member 34. With this braking force, the frame body 311 side of the apparatus body 3 is braked, while the first edge block 312, the sliding door fixing body 2, and the sliding door D are advanced by inertial force or closing operation force, so that the base body 63 is relatively moved. Pulled to the left. Thus, the base body 63 slides relative to the auxiliary guide body 64, and the guide boss portion 65 moves along the boss insertion hole 63a and the inclined guide hole 62a. 62 is pushed downward (see FIG. 9). In other words, the auxiliary guide body 64 moves away from the base body 63 in accordance with the braking force, and the guide boss 65 moves relatively along the inclined guide hole 62a. Advance to D side. Along with this advancement, when the pressing portion 622 of the pressing block 62 presses the top surface of the sliding door D, it is possible to easily and reliably suppress the sliding door D from being flipped up. That is, the pressing unit 6 shifts from the initial state (see FIG. 8) to the pressed state (see FIG. 9).

  Moreover, the raising of the sliding door D is closely related to the closing speed of the sliding door D, and the higher the closing speed, the more feared that the sliding door D will jump up. However, in the slide assist device 1 of the present embodiment, the braking force is increased. Is due to the damper member 33, the higher the closing speed of the sliding door D, the greater the braking force. The greater the braking force, the greater the moving force between the base body 63 and the auxiliary guide body 64 in the separation direction. Accordingly, the pressing force against the sliding door D by the pressing block 62 also increases. Therefore, the slide assist device 1 equipped with the flip-up restraining device of the present embodiment can adjust the flip-up restraining force in accordance with the closing speed of the sliding door D, and can more easily and reliably bounce the sliding door D. Raising can be suppressed.

  Further, the pressing block 62 is incorporated in the apparatus main body 3 that slides when the sliding door D is opened and closed, and the pressing block 62 presses the top surface of the sliding door D that also slides, so that the pressing block 62 is a stationary member. There is no sliding contact, and it is possible to press more stably than when pressing a stationary member, and the sliding door D can be smoothly prevented from jumping up.

  After the slide block 341 is sufficiently decelerated, the biasing force by the tension spring 32 exceeds the braking force by the damper member 33. Accordingly, the slide member 34 moves from the holding position side toward the initial position relative to the frame body 31 along the guide slit 311 a while being given a certain resistance by the damper member 33.

  At this time, in the pressing unit 6, the base body 63 is pushed toward the auxiliary guide body 64 by the urging force of the pulling spring 32, and the base body 63 slides relative to the auxiliary guide body 64 in the proximity direction. Accordingly, the guide boss 65 moves along the boss insertion hole 63a and the inclined guide hole 62a. With this movement, the pressing block 62 is pushed upward, and the pressing unit 6 shifts from the pressing state to the initial state (see FIG. 8).

  The slide assist device 1 described above is an embodiment of an assist device equipped with the sliding door flip-up suppressing device according to the present embodiment, and the specific configuration and the like can be changed as appropriate. Hereinafter, modifications of the present embodiment will be described.

As shown in FIG. 10, it may be configured integrally. That is, the slide member 134 shown in FIG. 10 includes a slide block 135 and a rotation engagement piece 136 pivotally supported on the slide block 135 by a rotation shaft 137, and one end protrusion 136 a of the rotation engagement piece 136 is provided. The tongue piece 342c in the above embodiment plays a role, and the other end protruding portion 136b plays the role of the protruding engaging portion 341b and one end portion of the triangular block 342b (the left end portion in FIGS. 6 and 7). In this way, by integrally configuring the slide block, it is possible to further simplify the configuration by reducing the component configuration.

If the auxiliary guide body is installed so as to be relatively movable with respect to the base body, the same action as in the present embodiment can be exhibited. In this case, the pressing block presses the lower surface of the apparatus main body 3.

  (3) In the above embodiment, the base block 21 of the sliding door fixing body 2 is embedded in the top of the sliding door D, but the fixing position of the base block 21 with respect to the sliding door D is limited to that in the present embodiment. For example, the front (or the back) of the sliding door D may be used.
