  The main problem to be solved by the present invention is that after the movable body has been moved forward to the self-running start position, a structure that can be reliably moved to the stop position by the self-running forward movement of the movable body. This is in that the space for providing this structure in the left-right direction can be provided without excessively large space.

In order to achieve the above object, in the present invention, the self-propelled forward movement mechanism of the movable body has the following configurations (1) to (8).
(1) A mechanism that supports a movable body that is supported by placing the upper part in a rail-like body, and after the movable body has been moved forward to a self-running start position,
(2) a striker body provided in a rail-shaped body;
(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 catcher is provided with a catcher stopper that can be moved in and out of the catcher main body, a striker holding body that can be moved back and forth, and that accepts the striker body from the front in a non-holding state. Have power,
(6) By this urging body, when the catcher stopper is projected from the catcher main body, 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. The catcher stopper is drawn into the main body of the catcher when in the holding state,
(7) A catching hole for the catcher stopper at the time of protrusion is formed in the recess, and energy is accumulated in the urging means at the reference position of the catcher in which the catcher stopper is engaged with the catching hole. And
(8) When the movable body is moved forward to the self-running start position, the striker body enters the holding body of the catcher at the reference position, and the engagement between the catcher stopper and the engagement hole is released, and the urging means The self-running movement of the movable body is made .

  In a stage before the movable body is moved forward to the self-propelled start position, the holding body protrudes most forward, and the catcher stopper is also engaged with the engagement hole. (Reference position of catcher) When the movable body moves forward to the self-propelled start position, the striker body enters the recess from the front, and is pushed by the striker body that has entered in this way, It is moved backward against the bias. When the holding body is moved backward, the holding body is positioned in the holding state. Thereby, the catcher captures the striker body and is integrated. At the same time, the catcher stopper is drawn into the main body of the catcher by the rearward movement of the holding body and comes out of the engagement hole. In this way, when the engagement between the catcher stopper and the engagement hole of the case is released, the movable body can be self-propelled to the stop position by the urging means. 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 relatively moved 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 body is released from the holding body and the catcher and the striker body are separated. Since the holding body only moves along the moving direction of the movable body between the forward movement position and the backward movement position, in this self-propelled forward movement mechanism, the horizontal dimension of the movable body is minimized. It has features that can be made.

  A slide body in which the holding body is combined with a catcher main body so as to be movable back and forth, and a pair of left and right holding pieces, by a resin hinge portion extending between the front end of the slide body and the rear end of the holding piece. It may be configured to be integrally connected.

  In this case, when the movable body is moved forward to the self-running start position and pushed by the striker body and the holding body is moved backward against the urging force of the urging body, the resin hinge portion is moved. It is possible to hold the striker body that has entered while narrowing the interval between the pair of holding pieces while being elastically deformed.

  A notch portion is formed on a part of the inner wall along the moving direction of the movable body constituting the recess, so that at least the outer surface side of the holding piece of the catcher at the reference position is inserted by the elasticity of the resin hinge portion. Sometimes it is left.

  In such a case, the holding body is notched between the pair of holding pieces by the notch portion without increasing the horizontal dimension of the self-running forward movement mechanism until the movable body is moved forward to the self-running start position. The movable body can be moved to the self-propelled start position and pushed by the striker body so that the holding body can move backward against the bias of the biasing body. When moved, the holding piece is pulled out from the notch, and the resin hinge part is elastically deformed by the left and right side walls of the case, and the interval between the pair of holding pieces is narrowed. Can be produced.

  Including a spacer tool including protruding sliders protruding laterally on both the left and right sides of the movable body so that a gap is always formed between the inner surface of the rail-shaped body and the left and right surfaces of the movable body. A traveling mechanism may be configured. Further, in this case, it is also possible to provide the spacer member with an elastic piece that can be elastically deformed in a direction away from the inner surface of the rail-like body, and to provide a protruding slider on the elastic piece. is there.

  In this case, the upper part of the movable body is not in contact with the inner surface of the rail-like body, and the sliding resistance when moving the movable body to the rail-like body via the projecting slider is minimized. In addition, it can be supported without rattling. In addition, the spacer can be centered so that the position of the movable body approximately in the middle in the width direction is positioned at the position approximately in the middle of the rail-shaped body in the width direction. When it has been done, the striker body can be surely captured by the catcher at the reference position in the recess. In addition, if the elastic piece portion is provided with the protruding slider, the movable body is deformed by deforming the elastic piece portion when a pressing force directed to the left or right side of the rail-like body is applied to the movable body. The movable body can be allowed to move toward this side, and when the action of this force is lost, the movable body can be repositioned to the intended position by the elastic return of the elastic piece portion.

  Further, the striker body may be provided on a striker base having a pivot assembly part toward the rail-shaped body side with an interval in the moving direction of the movable body between the striker base and the pivot assembly part. In this case, even if the support position of the movable body with respect to the rail-shaped body has changed in the direction orthogonal to the moving direction of the movable body after attaching the striker body to the rail-shaped body side, The position of the striker body can be moved within the width of the rail-like body at the starting position of the self-propelled by the forward movement, so that the striker body can appropriately enter the holding body of the catcher. In this case, the striker base is further provided with a through-groove along a virtual circular arc whose center is the rotational assembly portion, and the rotation is performed by a shaft-like stopper fastened to the rail-like body side through the through-groove. If the movement is restricted, the striker body can be stably provided on the rail-like body side while allowing the movement of the position of the striker body.

  The striker body may be provided on a striker base that is attached to the rail-like body side so as to be movable in a direction substantially orthogonal to the moving direction of the movable body. Even in this case, even after the striker body is attached to the rail-shaped body side, even if the support position of the movable body with respect to the rail-shaped body has changed in the direction orthogonal to the moving direction of the movable body, the movable body By the forward movement, the position of the striker body can be moved within the width of the rail-like body at the self-running start position, so that the striker body can be appropriately entered into the holding body of the catcher.

  Further, the striker body may be provided with engaging portions for two or more holding bodies at intervals in the moving direction of the movable body. In this case, even when the striker body enters the holding body deeply or shallowly, the striker body and the catcher can be integrated by engaging the holding body with one of the engaging portions. it can.

  When a sliding door is configured by applying such a mechanism, after the sliding door is manually closed to the desired self-propelled start position (forward movement), the front end of this sliding door is a door stop or the front end of a sliding door that makes a pair, etc. To the stop position where it hits

  According to this invention, after the movable body has been moved forward to the self-propelled start position, the structure that can be reliably moved to the stop position by self-propelled forward movement is provided in the left-right direction of the movable body. The space for providing can be provided without requiring an excessive space.

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

Yes. 11 and 12 show the members constituting the catcher 2 as being separated from each other. Moreover, FIGS. 13-16 has shown the spacer tool 5 for forming a space | interval between the movable body M and the rail-shaped body R, respectively. FIGS. 17 to 19 show examples in which the striker body 1 is configured to be movable in the direction crossing the moving direction of the movable body M in the rail-shaped body R. 20 and 21 are other examples in which the striker body 1 is configured to be movable in the direction crossing the moving direction of the movable body M, and FIG. 22 is an example in which the configuration of the striker body 1 is changed. Is shown.

  The self-propelled forward movement mechanism according to this embodiment is configured such that the movable body M supported by the upper portion being accommodated in the rail-shaped body R is stopped after the movable body M is moved forward to the self-propelled start position. To self-propelled. As this movable body M, a sliding door, a suspension door, a folding door, etc. are typically planned.

  In the illustrated example, an example in which such a mechanism is applied to the sliding door M ′ is shown. The rail-shaped body R is configured to have a groove shape that accommodates the upper portion of the sliding door M ′. In this example, the rail-shaped body R is formed on the lower surface portion of the upper frame member W that defines an opening that can be opened and closed by the sliding door M ′. When such a mechanism is applied to the sliding door M ′, after the sliding door M ′ is manually closed to the desired self-propelled starting position (forward movement), the front end Ma of the sliding door M ′ is not touched by the door. It is possible to make a self-propelled drive to a stop position that hits the front edge of the sliding door.

  This mechanism includes (1) a striker body 1, (2) a catcher 2, and (3) an urging means 3 for the catcher 2.

  The striker body 1 is provided in the rail-shaped body R. The movable body M is moved forward from the position where the striker body 1 is captured by the catcher 2 to the stop position. In the illustrated example, the striker body 1 is configured to have an axial shape that protrudes downward in the vertical direction from the lower surface of the mounting portion 10, and the mounting portion 10 is fixed to the top surface Ra of the rail-shaped body R. As a result, the rail-shaped body R is provided in the rail-shaped body R so as to be positioned at a position approximately in the middle of the width direction of the rail-shaped body R. The striker body 1 enters the recess Mb from the open end Mc on the front end Ma side of the movable body M in the later-described recess Mb when the movable body M is moved forward to the self-running start position. It has become.

  17 to 19, the striker body 1 is placed on a striker base 10 ′ having a rotation assembly portion 11 toward the rail-shaped body R side in the moving direction of the movable body M between the rotation assembly portion 11 and the striker base 10 ′. An example is shown in which a space is provided. In this example, the striker base 10 ′ is configured to have a plate shape attached to the top surface Ra so that the top surface is in contact with the top surface Ra of the rail-shaped body R. The striker base 10 'is configured to be long in the moving direction of the movable body M and to have a width narrower than the width of the rail-shaped body R. The striker body 1 is configured so as to have a shaft shape integrally provided with an upper end of the shaft between both ends of the striker base 10 ′ and projecting downward in the vertical direction. The rotating assembly portion 11 is provided on the front end 10a side (the end located on the forward movement destination side of the movable body M) of the striker base 10 '. In this example, a stepped screw 12 is passed through a shaft hole 11a provided in the striker base 10 'in a penetrating state, and the screw 12 is fixed to the rail-shaped body R side, so that the striker is centered on the screw 12. The rear end 10b side of the base 10 ′ is movable within the width of the rail-shaped body R in a direction crossing the moving direction of the movable body M. In the illustrated example, a portion 12c between the step portion 12a and the head portion 12b of the screw 12 has an outer diameter substantially equal to the shaft hole 11a. Such a screw 12 is typically fastened at a position approximately in the middle of the rail-shaped body R in the width direction. In this case, after the striker body 1 is attached to the rail-shaped body R side, the movable body M with respect to the rail-shaped body R in the direction orthogonal to the moving direction of the movable body M (the front-back direction in the case of the sliding door M ′). Even if the support position of the catcher 2 is changed, the position of the striker body 1 is moved within the width of the rail-like body R at the self-running start position by the forward movement of the movable body M. The striker body 1 can be appropriately entered into the holding body 22. Specifically, the opening 41 of the case 4 to be described later is inclined so as to gradually narrow the left and right internal dimensions of the case 4 as it approaches the intermediate position between the pair of holding pieces 225 and 225 of the holding body 22. A guide surface 41a is formed, and even if a deviation occurs in the relative position of the striker body 1 in the range between the left and right guide surfaces 41a, 41a, the striker body 1 is moved by the guide surface 41a and a pair of holding pieces The striker body 1 appropriately enters between 225 and 225. Further, in this example, the striker base 10 ′ is configured to gradually increase in width toward the rear end 10b side, and a virtual assembly with the rotational assembly portion 11 being a center on the rear end 10b side. Is provided with a through groove 13 along the circular arc of the circle, and its rotation is regulated by a stepped screw 12 as a shaft-like stopper fastened to the rail-like body R side through the through groove 13. It has become. The groove width of the through groove 13 is substantially equal to the outer diameter of the location 12c between the step 12a and the head 12b of the screw 12. Thereby, in this example, the striker body 1 can be stably provided on the rail-like body R side while allowing the movement of the position of the striker body 1.

  20 and 21 show an example in which the striker base 10 ′ is attached to the rail-like body R side so as to be movable in a direction substantially orthogonal to the moving direction of the movable body M, and the striker body 1 is provided. In the example shown in FIG. 20, the striker base 10 ′ is configured to fit within the width of the rail-shaped body R and form a long plate shape in the moving direction of the movable body M. The striker body 1 The upper end of the shaft is integrally provided at a position approximately in the middle of the length direction of ', and is configured to have a shaft shape protruding downward in the vertical direction. In the example shown in FIG. 20, through-grooves 14 extending in the width direction are formed on both end sides of the striker base 10 ′, and screws are fastened to the rail-shaped body R side through the through-grooves 14. As a result, the striker base 10 ′ and the striker body 1 are attached to the rail-like body R side in a movable state in a direction substantially perpendicular to the moving direction of the movable body M. Further, in the example shown in FIG. 21, the striker base 10 ′ is stored in the base case 15. The base case 15 is formed with two screw through holes 15a at intervals in the moving direction of the movable body M, and the striker base 10 is secured to the rail-like body R through the through holes 15a. 'Is attached to the rail-shaped body R side. The striker body 1 is configured to have a shaft shape in which a shaft upper end is integrally provided on the lower surface of the striker base 10 ′ and protrudes downward in the vertical direction. On the lower surface of the base case 15, a through hole 15 b that extends long in a direction orthogonal to the moving direction of the movable body M that projects the striker body 1 is formed. In the example shown in FIG. 21, the striker base 10 ′ housed in the base case 15 is configured to have a width that can move in the direction perpendicular to the moving direction of the movable body M in the base case 15. Thus, the striker body 1 is attached to the rail-shaped body R side in a movable state in a direction substantially orthogonal to the moving direction of the movable body M. 20 and FIG. 21 also, after attaching the striker body 1 to the rail-shaped body R side, the direction perpendicular to the moving direction of the movable body M (the front-rear direction of the sliding door M ′) Even if the support position of the movable body M with respect to the rail-shaped body R is changed in step S1, the position of the striker body 1 is moved within the width of the rail-shaped body R at the self-running start position by the forward movement of the movable body M. It can be made to move and the striker body 1 can be appropriately approached in the holding body 22 of the catcher 2 mentioned later.

  FIG. 22 shows an example in which the striker body 1 is provided with hooking portions for the holding bodies 22 of the catchers 2 at two or more places with an interval in the moving direction of the movable body M.

Is positioned in a non-holding state where the diameter is larger than the diameter of the striker body 1.

  Specifically, the right holding piece 225 is joined to the slide body 221 by a resin hinge portion 227 extending between the rear end of the right holding piece 225 and the right front corner of the slide body 221. The left holding piece 225 is joined to the slide body 221 by a resin hinge 227 extending between the rear end of the left holding piece 225 and the left front corner of the slide body 221. When the catcher 2 is positioned at the reference position, the holding body 22 is in the forward movement position. In this state, the holding piece 225 spreads outward by the elasticity of the resin hinge portion 227 by the cutout portion 441 of the case 4. It is allowed to be put out. (FIG. 6 / The outer surface side of the holding piece 225 enters the notch 441.) When the movable body M is moved forward to the self-propelled start position, the front end of the slide body 221 located between the rear ends of the pair of holding pieces 225 and 225. The striker body 1 comes into contact with the slide body 221, that is, the holding body 22 is pushed toward the retracted position. In the illustrated example, the front end of the slide body 221 is covered with a cushion material 223. When the holding body 22 is pushed into the retracted position, the pair of holding pieces 225 and 225 are respectively pulled out from the cutout portions 441 and pushed by the side walls 44 of the case 4 so that they are inwardly narrowed and the interval between the overhanging portions 226 is increased. The striker body 1 is held in the back of the overhanging portion 226 so as to be narrower than the diameter. As a result, the striker body 1 is captured by the catcher 2.

  In addition, the left and right frame plates of the slide body 221 are each formed with a curved guide groove 222 formed so that the upper end of the groove is positioned forward, the lower end of the groove is positioned rearward, and the lower front is inclined outward. Has been.

  Further, vertical guide grooves 207 are formed through the respective left and right side portions of the catcher main body 20 where the horizontal operation hole 203 and the vertical operation hole 202 intersect.

  In the illustrated example, the slide body 221 of the holding body 22 is inserted into the lateral movement hole 203 with the shaft portion 224 first, and the catcher is inserted into the slide body 221 of the holding body 22 from the vertical movement hole 202. The stopper 21 is inserted, and in this state, the catcher stopper 21 and the holding body 22 are assembled to the catcher main body 20 through the pins 24 through the vertical guide grooves 207, the curved guide grooves 222, and the pin through holes 212. A compression coil spring 231 is wound around the shaft portion 224 of the holding body 22, and the compression coil spring 231 always presses the rear end of the spring against the inner back of the laterally operating hole 203 and slides the front end of the spring. The body 221 is always pressed against the rear end.

  The holding body 22 is always urged forward by the compression coil spring 231, and the catcher stopper 21 is always urged downward via the holding body 22 urged in this way. That is, in the illustrated example, the compression coil spring 231 functions as the biasing body 23.

  In a stage before the movable body M is moved forward to the self-running start position, the holding body 22 protrudes most forward, whereby the pin 24 has a groove lower end of the vertical guide groove 207 and a groove lower end of the curved guide groove 222. The catcher stopper 21 has its lower end inserted into the engagement hole 402. (FIG. 5, reference position of catcher 2) When the movable body M is moved forward to the self-propelled start position, the striker body 1 enters the recess Mb from the front and is pushed by the striker body 1 that has entered in this way. The holding body 22 is moved backward against the urging force of the urging body 23. (FIG. 5 to FIG. 7) The rearward movement of the holding body 22 is permitted by inserting the shaft portion 224 into the escape gap 206 through the through hole 205. When the holding body 22 is moved rearward, the holding piece 225 comes out of the notch 441 of the case 4 and the pair of holding pieces 225 while elastically deforming the resin hinge portion 227 by the left and right side walls 44 and 44 of the case 4. 225 is positioned in a holding state in which the distance between the tops of the overhang portions 226 is smaller than the diameter of the striker body 1. Thereby, the catcher 2 is integrated with the striker body 1. At the same time, the catcher stopper 21 is moved upward by the rearward movement of the holding body 22 and comes out of the engagement hole 402 provided in the case 4. When the catcher stopper 21 and the engagement hole 402 of the case 4 are thus disengaged, the elastic return in the direction in which the tension coil spring 30 is contracted is allowed, so that the movable body M is self-propelled to the stop position by this elastic return. The (FIGS. 8 to 10) During this self-running, the roller 211 of the catcher stopper 21 is rotated in contact with the upper surface on both sides of the slot 401 of the partition 40 of the case 4 to be advanced, and the self-running movement is finished. The catcher 2 is relatively retracted to a position approximately in the middle of the length direction of the case 4.

  Note that the catcher 2 integrated with the striker body 1 is moved relatively forward while accumulating in the biasing means 3 by the backward movement of the movable body M from the stop position, and the movable body M starts to self-run. When the position is reached, the catcher stopper 21 is inserted into and engaged with the engaging hole 402 of the case 4 by the urging force of the urging body 23 again. At the same time, the forward movement of the holding body 22 by the biasing body 23 is allowed, and the holding body 22 is returned to the non-holding state, and the catcher 2 and the striker body 1 are separated. (FIG. 5) Thereby, the initial state is restored.

  In the illustrated example, a cam follower portion 228 that protrudes downward is formed on each of the front end sides of the pair of holding pieces 225 and 225 of the holding body 22, and the upper surface of the front end of the partition body 40 of the case 4 Is formed with a cam portion 49 that guides the cam follower portion 228 and allows the holding piece 225 to enter the cutout portion 441 of the case 4 when the movable body M is moved back to the self-running start position. .

  In this embodiment, a damper device 6 is incorporated in the recess Mb to apply braking to the relative movement of the catcher 2.

  In the illustrated example, a damper device 6 is provided that includes a cylinder 60 and a piston (not shown) in the upper chamber 48 of the case 4, and is configured to give resistance to the entry when the piston enters the cylinder 60. ing. In the illustrated example, the rear end of the cylinder 60 is fixed to the rear end of the case 4, and the front end of the piston rod 61 is fixed to the rear end of the catcher 2, and the piston rod 61 is at the reference position of the catcher 2. From the inside of the cylinder 60. In the illustrated example, the position where the piston rod 61 enters the cylinder 60 to the maximum is the limit position for the relative backward movement of the catcher 2. As a result, in this embodiment, the momentum of the relative movement of the catcher 2 due to the self-running movement of the movable body M ahead of the self-running start position is moderately relaxed, and the movable body M has a high-class feeling of self-running. Is added, and the collision sound at the time of the stop is reduced.
