Description

  The present invention relates to a mechanism for allowing a movable body supported by being suspended from a rail by a suspension vehicle to self-run to a stop position after the movable body has been moved to a self-run start position.

  In the case of a movable body that is suspended and supported on a rail by a suspension vehicle such as a hanging door, the end surface (front end) located in front of the forward movement usually hits the end surface of a door or a pair of hanging doors. It is manually moved to the stop position. Here, if the force of this manual forward movement is too strong, the movable body that has been moved forward will rebound from the stop position. On the other hand, if the momentum of this manual forward movement is too weak, the movable body stops before reaching the stop position.

  The main problem to be solved by the present invention is that, after a movable body such as this kind of hanging door is manually moved forward halfway, the movable body is moved forward from there and reliably moved to its stop position. It is in the point to make.

In order to achieve the above object, according to the present invention, the self-propelled forward movement mechanism of the movable body has the following configurations (1) to (10).
(1) A mechanism that allows a movable body supported by being suspended from a rail by a suspension car to self-propelled to a stop position after the movable body has been moved to a self-propelled start position,
(2) a runner combined with the rail so that it can run;
(3) a catcher that is movably accommodated along the moving direction in a recess that extends long along the moving direction of the movable body formed on the upper portion of the movable body;
(4) a catcher biasing means,
(5) The runner has a runner main body and a striker that protrudes downward from the runner main body and enters the recess and is positioned in front of the catcher.
(6) The runner main body is provided with a runner stopper which is incorporated in the runner main body so as to be movable up and down and presses the upper end against the upper inner surface of the rail by urging.
(7) The catcher is a catcher stopper provided to be movable up and down with respect to the catcher main body, a striker holding body that is provided to be movable back and forth and receives the striker from the front in a non-holding state, and urging thereof Has a body,
(8) With this urging body, when the catcher stopper protrudes the lower end downward, the holding body is in the forward movement position and in the non-holding state, and the holding body is in the backward movement position and is held. When in the holding state, the catcher stopper is designed to pull the lower end upward,
(9) A catching hole at the lower end of the catcher stopper is formed in the recess, and energy is accumulated in the biasing means at the reference position of the catcher in which the catcher stopper is engaged with the catching hole. And
(10) The rail has a hook hole at the upper end of the runner stopper, and the runner's runner stopper with the striker entering the catcher's holding body at the reference position moves to the position where the movable body starts to run automatically. When it has been done, it will be hooked into this hooking hole.

  In the stage before the movable body is moved forward to the self-propelled start position, the catcher holding body protrudes most forward, and the catcher stopper has its lower end inserted in the engagement hole of the recess. (Reference position of catcher) When the movable body is moved forward toward the self-running start position, the striker of the runner has entered the holding body in the non-holding state. When the runner stopper of the runner is engaged with the engagement hole of the rail and the runner is stopped, the runner is pushed by the striker and the holding body is moved backward against the bias of the biasing body. When the holding body is moved rearward, the holding body is positioned in the holding state, and the catcher is integrated with the stopped runner. At the same time, the catcher stopper is moved upward by the rearward movement of the holding body and comes out of the engagement hole provided in the recess. As described above, when the catcher stopper is disengaged from the engagement hole of the case, the stored power of the urging means is allowed to be released, so that the movable body can be self-propelled to the stop position. When the movable body that has been self-propelled to the stop position is moved back to the self-propelled start position, the catcher is moved relative to the reference position while accumulating the biasing means, and the catcher stopper is moved to the engagement hole in the recess. At the same time, the striker is released from the holding body, and the runner and the catcher are separated.

The runner main body of the runner is incorporated so that it can move back and forth, and the front end is projected toward the forward movement destination that is always forward by biasing, and the runner stopper is moved downward by pushing against the biasing. With release parts,
A suspension car is provided between the front end of the movable body and the recess,
In some cases, when the movable body at the stop position is moved backward, the suspension vehicle hits the release part to make the pushing operation.

  In this case, the engagement between the runner stopper and the rail engagement hole can be released by moving the movable body at the stop position back to the self-running start position.

  A damper device that applies braking to the relative movement of the catcher may be incorporated in the recess.

  In this case, the momentum of the relative movement of the catcher due to the self-running movement of the movable body ahead from the self-running start position is moderately relaxed to give a high-class feeling to the mobile body's self-running and at the time of stopping Impact noise can be reduced.

  According to the self-propelled forward movement mechanism according to the present invention, after the movable body has been moved forward to the self-propelled start position, the movable body can be moved forward to the stop position and reliably moved to the stop position.

  The best mode for carrying out the present invention will be described below with reference to FIGS.

  The self-propelled forward movement mechanism according to this embodiment is configured such that the movable body 1 supported by being suspended from the rail 2 by the suspension vehicle 10 is stopped after the movable body 1 is moved forward to the self-propelled start position SA. Self-propelled travel to SP. As the movable body 1, typically, a hanging door 1 'or a folding door is planned.

  Then, after the mechanism has manually moved the suspension door 1 ′ supported by the rail 2 so as to be movable along the rail 2 to the self-running start position SA, the mechanism moves to the stop position SP. In other words, typically, the end face (front end 11) positioned forward of the forward movement of the suspension door 1 ′ is self-propelled to a position where it abuts against the door stop or the end face 3 of the pair of suspension doors. Used.

  The mechanism includes (1) a runner 5, (2) a catcher 6, and (3) an urging means 7 for the catcher 6.

  The runner 5 is combined with the rail 2 so that it can run. The runner 5 includes a runner main body 50 that is substantially contained in the rail 2, and protrudes downward from the runner main body 50 into a recess 12 described later (in front of the catcher 6 in the recess 12 (the catcher 6 and the movable body 1). The striker 51 is located between the front end 11 of the first step and the second end.

  Further, the runner main body 50 is provided with a runner stopper 52 that is incorporated in the runner main body 50 so as to be movable up and down and that always presses the upper end against the upper inner surface of the rail 2 by urging.

  In the illustrated example, the rail 2 is configured to have an upper plate portion 20, left and right plate portions 21, 21, and a bent plate portion 22 protruding inward from the lower ends of the left and right plate portions 21, 21. . The rail 2 is attached to the ceiling 4 by being fitted into a groove 40 formed in the ceiling 4 with the upper plate portion 20 facing upward. The runner main body 50 has a central portion 501 that is long in the length direction of the rail 2 and includes left and right protruding portions 502 and 502, and the left protruding portion 502 is formed on the inner surface of the bent plate portion 22 of the left plate portion 21 of the rail 2. The right projecting portion 502 is accommodated in the rail 2 so as to be in sliding contact with the inner surface of the bent plate portion 22 of the right plate portion 21 of the rail 2. A lower portion of the center portion 501 protrudes downward from a gap 23 between the pair of bent plate portions 22 and 22 of the rail 2.

  A through-hole 503a penetrating through the central portion 501 in the vertical direction is formed on the rear end side of the central portion 501 of the runner main body 50 (the side facing the forward and backward side of the movable body 1). The through hole 503a is configured to have a large diameter on the upper side and a small diameter on the lower side, and has a step surface 503b facing upward in the middle. The striker 51 is formed in a rod shape having a small-diameter portion 512 below the large-diameter portion 511 and has a step surface 513 facing downward. In the illustrated example, the striker 51 is inserted from above into the through hole 503a until the step surface 513 hits the step surface 503b of the through hole 503a, and the central portion 501 is inserted into the stop hole 514 formed in the large diameter portion 511. The pin 503d is driven from the side using the formed stop hole 503c, and is assembled to the runner main body 50. The narrow diameter portion 512 of the striker 51 protrudes downward from the lower portion of the central portion 501 of the runner main body 50.

  Further, on the front end 11 side of the central portion 501 of the runner main body 50, a vertical operation hole 504 penetrating the central portion 501 in the vertical direction is formed. Further, the central portion 501 of the runner main body 50 is formed with a lateral movement hole 505 that forms a hole at the front end 11 and continues toward the rear end side of the central portion 501 and communicates with the vertical movement hole 504 in a cross shape. Has been. A clearance gap 506 is formed between the inner back portion of the lateral operation hole 505 and the through hole 503a, and a through hole 507 communicating with the escape clearance 506 is formed in the inner rear portion of the lateral operation hole 505. Is formed.

  In this embodiment, the front end of the runner main body 50 of the runner 5 is incorporated into the runner main body 50 so as to be movable forward and backward, and is always forwardly moved forward by biasing. A release part 53 that moves the runner stopper 52 downward by the resisting push is provided.

  In the illustrated example, the runner stopper 52 has a roller 521 at the upper end, and is configured to have a shaft shape with a pin through hole 522 penetrating in the left-right direction in the middle portion. It is comprised so that the upper end may be made to appear and disappear from the hole opening.

  On the other hand, the release part 53 has a rectangular frame portion 531 that is opened up and down, and a shaft portion 532 that protrudes rearward from the rear end of the rectangular frame portion 531. Each of the left and right frame plates of the rectangular frame portion 531 is formed with a curved guide groove 533 formed so that the lower end of the groove is positioned forward, the upper end of the groove is positioned rearward, and the upper front side is set to be curved outward. ing.

  In addition, vertical guide grooves 508 are formed through the left and right side portions of the center portion 501 of the runner main body 50 where the horizontal operation holes 505 and the vertical operation holes 504 cross each other.

  In the example shown in the drawing, the release part 53 is inserted into the horizontal operation hole 505 with the shaft portion 532 first, and the runner stopper 52 is inserted into the rectangular frame part 531 of the release part 53 from the vertical operation hole 504. In this state, the runner stopper 52 and the release part 53 are assembled to the runner main body 50 through the pins 509 through the vertical guide grooves 508 and 508, the curved guide grooves 533 and 533, and the pin through holes 522. A compression coil spring 534 is wound around the shaft portion 532 of the release part 53. The compression coil spring 534 always presses the rear end of the spring against the inner back portion of the laterally operating hole 505, and the front end of the spring is a rectangular frame. It is always pressed against the rear end of the portion 531.

  The release part 53 is always urged forward by the compression coil spring 534, and the runner stopper 52 is always urged upward through the release part 53 thus urged.

  In a stage before the movable body 1 is moved forward to the self-running start position SA, the release part 53 protrudes most forward, whereby the pin 509 has a groove upper end of the vertical guide groove 508 and a groove upper end of the curved guide groove 533. The runner stopper 52 is positioned at a protruding position where the roller 521 is pressed against the upper inner surface of the rail 2. In the illustrated example, the engagement hole 241 of the rail 2 to be described later is configured by a recess 242 formed in the hole plug body 24 fitted in the attachment hole 25 formed in the upper plate portion 20 of the rail 2. The inner depth level of the recess 242 of the hole plug body 24 is substantially equal to the level of the inner surface of the upper plate portion 20 of the rail 2. In addition, an inclined surface 243 is formed on the rear side of the hole plug body 24 so as to gradually protrude downward toward the front (the forward movement destination side of the movable body). A recess 242 is formed in front of the inclined surface 243. Is located. When the movable body 1 is moved forward to the self-running start position SA, the movable body 1 is pushed forward by the holding body 62 of the catcher 6 housed in a recess 12 described later of the movable body 1. The runner stopper 52 of the runner 5 is pushed down by the inclined surface 243 against the urging force, and protrudes again by the urging at a position over the inclined surface 243 and enters the engaging hole 241 and is engaged therewith. (FIG. 4) Thereby, the runner 5 is stopped. Further, when the movable body 1 that has been self-propelled to the stop position SP is moved back to the self-propelled start position SA (FIGS. 6 to 9), as will be described later, the release part 53 in the runner 5 stopped in this way The suspension vehicle 10 is pushed from the front and the release part 53 is moved backward against the bias. The rearward movement of the release part 53 is allowed by inserting the shaft portion 532 into the escape gap 506 through the through hole 507. As the release part 53 is moved rearward, the runner stopper 52 is moved downward and comes out of the engagement hole 241, and the runner 5 is also moved backward together with the backward movement of the movable body 1. (Fig. 11)

  On the other hand, the catcher 6 is housed in a recess 12 which is formed in the upper part of the movable body 1 and continues long along the movement direction of the movable body 1 so as to be movable along the movement direction.

  In the example shown in the figure, a suspension wheel 10 is provided on the upper portion of the front door 11 side of the suspension door 1 ′ as the movable body 1. In addition, a built-in recess 13 of the case 14 that is opened upward and extends long in the moving direction of the suspension door 1 ′ is formed at the upper portion of the suspension door 1 ′ with a slight gap between the suspension vehicle 10 and the suspension door 10 ′. ing. In the example shown in the drawing, an elongated case 14 having an open upper surface is inserted into the built-in recess 13, and the catcher 6 is movably accommodated in the length direction of the case 14 and the suspension door 1 ′ side. Is equipped with a catcher 6. That is, in the illustrated example, the inside of the case 14 functions as the recess 12.

  The case 14 is roughly divided into upper and lower portions by a partition 141 formed at a position approximately in the middle in the vertical direction. A slot 142 is formed in the partition 141 between the front end side of the case 14 and the center thereof at a position approximately in the middle in the width direction, and is formed at the rear end of the catcher main body 60 described later of the catcher 6. The hook portion 601 enters the lower chamber 143 of the case 14 through the slot 142. In the lower chamber 143, a tension coil spring 145 having a spring front end fixed to the hook portion 601 of the catcher main body 60 and a spring rear end fixed to a hook portion 144 formed at the rear end of the case 14. Is paid. Further, the partition 141 between the front end of the slot 142 and the front end of the case 14 is formed with a recess 146 directed downward, and a catcher 6 stopper described later is a reference position of the catcher 6 into the recess 146. In R, the tension coil spring 145 is extended most. In other words, in the illustrated example, the recess 146 functions as the engagement hole 147 of the catcher stopper 61. Further, the left and right side walls of the case 14 are notched between the engagement hole 147 and the front end of the case 14, and a holding piece 623 of a holding body 62 (to be described later) of the catcher 6 at the reference position R is this notch. 148 enters and is not hugged. (Figure 3)

  The catcher 6 includes a catcher stopper 61 that can move up and down with respect to the catcher main body 60, a holding body 62 of the striker 51 that can be moved back and forth and receives the striker 51 from the front in a non-holding state, These urging bodies 63 are provided. When the catcher stopper 61 protrudes the lower end of the catcher stopper 61 downward by the biasing body 63, the holding body 62 is in the forward movement position and is in the non-holding state, and the holding body 62 is in the backward movement position. When it is in the holding state, the catcher stopper 61 has its lower end retracted upward.

  In the illustrated example, the catcher main body 60 is configured so as to be long in the moving direction of the movable body 1 and fit within the width of the upper chamber 149 of the case 14. The hook portion 601 is formed at the lower part of the rear end side of the catcher main body 60.

  On the front end side of the catcher main body 60, a vertical operation hole 602 penetrating in the vertical direction is formed. Further, the catcher main body 60 is formed with a lateral operation hole 603 that is formed in a hole at the front end thereof and continues toward the rear end side of the catcher main body 60 and communicates with the vertical operation hole 602 in a cross shape. A clearance gap 604 is formed between the inner back portion of the lateral movement hole 603 and the rear end of the catcher main body 60, and a passage communicating with the escape gap 604 is formed in the inner depth portion of the lateral movement hole 603. A hole 605 is formed.

  In the illustrated example, the catcher stopper 61 has a roller 611 at the lower end and is configured to have an axial shape with a pin through hole 612 penetrating in the left-right direction in the middle portion. It is comprised so that the lower end may be made to appear and disappear from the hole of the side.

  On the other hand, the holding body 62 includes a rectangular frame portion 621 that is opened up and down, a shaft portion 622 that protrudes rearward from the rear end of the rectangular frame portion 621, and a pair of holding members provided at the front end of the rectangular frame portion 621. And holding pieces 623 and 623. The pair of holding pieces 623 and 623 has a protruding portion 623a that protrudes inwardly on the side facing each other. The pair of holding pieces 623 and 623 are respectively integrated with the rectangular frame portion 621 via an elastically deformable resin hinge portion 623b, and the elasticity of the resin hinge portion 623b makes it between the top portions of the overhang portions 623a. It is positioned in a non-holding state in which the interval is larger than the diameter of the striker 51 of the runner 5. Further, the left and right frame plates of the rectangular frame portion 621 are respectively provided with curved guide grooves 624 formed so that the upper end of the groove is located forward, the lower end of the groove is located rearward, and the obliquely lower front is defined as the curved outer side. Is formed.

  Further, vertical guide grooves 606 are formed through the left and right side portions of the catcher main body 60 where the horizontal operation holes 603 and the vertical operation holes 602 cross each other.

  In the illustrated example, the holding body 62 is inserted into the lateral movement hole 603 with the shaft portion 622 first, and the catcher stopper 61 is inserted into the rectangular frame 621 of the holding body 62 from the vertical movement hole 602. In this state, the catcher stopper 61 and the holding body 62 are assembled to the catcher main body 60 through the pins 607 in the vertical guide grooves 606, 606, the curved guide grooves 624, 624, and the pin through holes 612. . A compression coil spring 625 is wound around the shaft portion 622 of the holding body 62. The compression coil spring 625 always presses the rear end of the spring against the inner back portion of the laterally operating hole 603, and the front end of the spring is square. It is always pressed against the rear end of the frame portion 621.

  The holding body 62 is always urged forward by the compression coil spring 625, and the catcher stopper 61 is always urged downward via the holding body 62 thus urged. That is, in the illustrated example, the compression coil spring 625 functions as the biasing body 63.

  In a stage before the movable body 1 is moved forward to the self-running start position SA, the holding body 62 protrudes most forward, whereby the pin 607 has a groove lower end of the vertical guide groove 606 and a groove of the curved guide groove 624. The catcher stopper 61 is positioned at the lower end, and the lower end thereof is inserted into the engagement hole 147. (FIG. 1, reference position R of catcher 6) When the movable body 1 is moved forward toward the self-running start position SA, the striker 51 of the runner 5 holds the pair of the holding bodies 62 in the non-holding state. It has entered between the pieces 623 and 623 to a position where it hits the front end of the rectangular frame portion 621. When the runner stopper 52 of the runner 5 is engaged with the engagement hole 241 of the rail 2 and the runner 5 is stopped, the striker 51 pushes the holding body 62 against the urging force of the urging body 63. Moved to. (FIGS. 5 to 7) The rearward movement of the holding body 62 is allowed by inserting the shaft portion 622 into the escape gap 604 through the through hole 605. When the holding body 62 is moved rearward, the holding piece 623 is pulled out from the notch 148 of the case 14 and the pair of holding pieces 623 and 623 are formed while the resin hinge portion 623b is elastically deformed by the left and right side walls of the case 14. It is positioned in a holding state in which the interval between the tops of the overhang portions 623a is smaller than the diameter of the striker 51 of the runner 5. (FIG. 8) Thereby, the catcher 6 is integrated with the stopped runner 5. At the same time, the catcher stopper 61 is moved upward by the rearward movement of the holding body 62 and comes out of the engagement hole 147 provided in the case 14. Thus, when the catcher stopper 61 and the engagement hole 147 of the case 14 are disengaged, elastic return in the direction in which the tension coil spring 145 contracts is allowed, so that the movable body 1 is self-propelled to the stop position SP by this elastic return. Is done. (FIG. 6) During this self-running, the roller 611 of the catcher stopper 61 is rotated in contact with the upper surface of the partition body 141 of the case 14 to be advanced, and when the self-running movement is completed, the catcher 6 is moved in the length direction of the case 14 It is relatively retracted to a substantially middle position.

  In this embodiment, the suspension vehicle 10 is provided between the front end 11 of the movable body 1 and the recess 12, and this suspension vehicle is moved when the movable body 1 at the stop position SP is moved backward. 10 hits the release part 53 to make the push-in.

  Specifically, the movable body 1 moves backward from the stop position SP so as to abut against the runner 5 in which the main body 101 of the suspension vehicle 10 is stopped in the rail 2 from the front.

  Thereby, in this embodiment, the engagement between the runner stopper 52 and the engagement hole of the rail 2 can be released by moving the movable body 1 at the stop position SP back to the self-running start position SA. It is like that. Thereby, the runner 5 can be moved back to an appropriate position along the rail 2 together with the movable body 1.

  The catcher 6 integrated with the stopped runner 5 is moved relatively forward while accumulating in the biasing means 7 by the backward movement of the movable body 1 from the stop position SP. When the self-propelled starting position SA is reached, the catcher stopper 61 is inserted into and engaged with the engaging hole 147 of the case 14 by the urging body 63 again. (FIG. 9) At the same time, the forward movement of the holding body 62 by the urging force of the urging body 63 is allowed, the holding body 62 is returned to the non-holding state, and the catcher 6 and the striker 51 are separated. (FIG. 11) Thereby, the initial state is restored.

  In this embodiment, a damper device 15 is incorporated in the recess 12 to apply braking to the relative movement of the catcher 6.

  In the illustrated example, the upper chamber 149 of the case 14 includes a cylinder 151 and a piston (not shown), and a damper device 15 configured to give resistance to the entry when the piston enters the cylinder 151 is housed. ing. In the illustrated example, the rear end of the cylinder 151 is fixed to the rear end of the case 14, and the front end of the piston rod 152 is fixed to the rear end of the catcher 6. 152 protrudes most from the cylinder 151. In the illustrated example, the position where the piston rod 152 enters the cylinder 151 to the maximum is the limit position of the relative backward movement of the catcher 6.

  As a result, in this embodiment, the momentum of relative movement of the catcher 6 due to the self-propelled forward movement of the movable body 1 from the self-propelled start position SA is moderately relaxed, so that the movable body 1 is high-grade. A feeling can be given and the collision sound at the time of the stop can be reduced.
