Definitions

  • This invention relates to an improvement of an apparatus for forcibly moving various kinds of movable bodies from a prescribed position up to a position at end of movement, and for applying a damping force to this forcible movement.
  • Patent Document 1 An example of a movement-assisting and shock-absorbing mechanism (assisting apparatus) of a sliding door using a so-called piston damper is given in Patent Document 1.
  • contacting bodies for contacting with contacted bodies provided respectively on the left and right on an upper part of a door frame, are provided respectively on a leading end of a piston rod and a rear end of a cylinder, and a tension coil spring for normally urging in a direction narrowing a space between both contacting bodies is provided.
  • both contacting bodies are held by magnetic force of holding bodies in a state in which the spring is stretched to the limit.
  • the contacting body collides with the contacted body at mid-course and is attracted thereto, and holding by the holding body is released.
  • the holding is released, the contacting body on the left side is relatively moved to the right side by the action of the spring, and the sliding door is forcibly moved to the left side in the amount of this movement.
  • the piston of the piston damper is pushed in at this time, and a damping force based on a fluid resistance inside the piston damper is applied to this movement.
  • Patent Document 1 Patent No. 3984645
  • a main problem to be solved by this invention is to ensure that a return operation of a movable body having been forcibly moved to a position at end of movement can be performed as smoothly as possible in this kind of assisting apparatus of a movable body.

  • the forcible moving mechanism includes a latch body supported to move slidably between a standby position and a drawn-in position on an apparatus base body, and a first urging body for applying an urging force toward the drawn-in position to the latch body in the standby position, and is configured so that the striker body is captured at the prescribed position by the latch body held in the standby position, the movable body is moved up to the position at end of movement by movement or relative movement of the latch body to the drawn-in position by release of the hold on the occasion of the capture, and the latch body releases the striker body at the prescribed position and is held again in the standby position during return movement of the movable body.
  • the damping mechanism includes a contact part for contacting with the latch body constituting the forcible moving mechanism, constituted so as to apply a resistance to a retraction of the contact part accompanying the movement of the latch body to the drawn-in position, and includes a second urging body for urging the contact part in an advancing direction.
  • the latch body having captured the striker body is relatively moved to the drawn-in position by the urging of the first urging body whereby the contact part is retracted, and the fluid resistance of the damping mechanism is applied as a damping force to the forcible movement of the movable body.
  • the second urging body urges the contact part in the advancing direction to the extent that the contact part is retracted, and the urging force of the second urging body also is applied as a damping force on the forcible movement of the movable body.
  • the contact part is advanced by the urging of the second urging body in the amount that the latch body moved toward the standby position, and the fluid resistance of the damping mechanism is therefore not applied to the return operation of the movable body.
  • Two forcible moving mechanisms may be provided, and the two forcible moving mechanisms may be arranged so that rear end sides of the latch bodies are brought to face opposite each other; the damping mechanism may be interposed between the rear ends of the latch bodies of the two forcible moving mechanisms, so that the contact part contacts the rear end of the latch body of one forcible moving mechanism and an opposite part opposite the contact part contacts or connects to the rear end of the latch body of the other forcible moving mechanism; and a fluid resistance of the damping mechanism may be applied to a retraction or relative retraction of the contact part narrowing a space between the contact part and the opposite part.
  • a damping force can be applied through the fluid resistance to the forcible movement by the urging of the first urging body ahead from the prescribed position, both when the movable body is moved to slide to the one side and when the movable body is moved to slide to the opposite other side.
  • a resistance-producing body in the damping mechanism may be a damper in which a fluid resistance of a fluid inside a cylinder is applied to a retraction or relative retraction of a piston, and the contact part may be formed on a projecting end part of a piston rod in the damper or on an outer end part of the cylinder opposite the projecting side of the piston rod.
  • the second urging body may be interposed between an inner depth part of the cylinder and the piston inside the cylinder, or between the cylinder and the latch body connected to the projecting end part of the piston rod outside the cylinder.
  • the piston is moved accompanying the movement to the drawn-in position of the latch body constituting the forcible moving mechanism after capturing the striker body, whereby the damping force of the damper can be applied to this movement as well as to the movement of the movable body.
  • the piston can be returned to the position before retraction by such second urging body, and the contact part of the damping mechanism can again contact or approach the rear end of the latch body being held again in the standby position.
  • the movable body in forward movement of the movable body, the movable body can be forcibly moved from a prescribed position and a damping force can be applied to this movement, and in return operation of the movable body from a position at end of movement, this return movement can be performed as smoothly as possible without action of the damping mechanism.

  • the latch body 10 of the forcible moving mechanism 1 on the right side is relatively moved toward the standby position while causing force to accumulate in the first urging body 11, releases the striker body S on the right side at the prescribed position, and is held again on the right end of the apparatus base body 3. During this time, the latch body 10 of the forcible moving mechanism 1 on the left side continues to be held on the left end of the apparatus base body 3 in the standby position.
  • the latch body 10 of the forcible moving mechanism 1 on the left side is held on the left end of the apparatus base body 3 in the standby position, captures the striker body S on the left side at the prescribed position during movement of the sliding door Ma to the left side, and is relatively moved to the drawn-in position on this occasion, whereby the sliding door Ma is forcibly moved to the left side up to the position at end of movement where the left end of the sliding door Ma is caused to collide with the doorstop Fc on the left side of the door frame Fa ( FIG. 1 to FIG. 3 ).

  • the latch body 10 When the catch-coupled parts 102e reach the position entering into the split groove 30a, the latch body 10 is relatively moved up to the drawn-in position by the urging of the first urging body 11, and the pair of holding pieces 102a and 102a is held between the side walls 33 of the upper chamber 31 of the apparatus base body 3 and is held in a state in which the front end sides are closed.
  • the pair of holding pieces 102a and 102a is such that the sliding door Ma is moved forward until reaching the position at end of movement in the amount of this movement.
  • the front end parts of the pair of holding pieces 102a and 102a constituting the catcher 102 are received in the window holes 34 by the advance of the plunger 103 and the front end side is opened, the striker body S is released, the catch-coupled parts 102e are caught again on the catch-coupling parts 30c, and the latch body held in the standby position ( FIG. 11 to FIG. 10 ).
  • a resistance-producing body 23 in the damping mechanism 2 is a damper 230 in which a fluid resistance of a fluid inside a cylinder 230a is applied to a retraction or relative retraction of a piston not illustrated.
  • damper 230 is referred to as "piston damper, or the like.” Silicon oil or other viscous fluid is typically used as such fluid, but it doesn't matter even if this is a gas.
  • Such piston is received inside the cylinder 230a so as to move reciprocally on the center line y of movement of the latch body 10.
  • a piston rod 230b is connected to this piston.
  • an outer end part of the cylinder 230a opposite the projecting side of the piston rod 230b in the damper serves as the contact body 20 for contacting with the rear end 100 of one latch body 10 (the latch body 10 on the right side in FIG. 5 ) of the two forcible moving mechanisms 1 and 1.
  • the leading end of the piston rod 230b serves as the opposite part 22 connected to the rear end of the other latch body 10 (the latch body 10 on the left side in FIG. 5 ) of the two forcible moving mechanisms 1 and 1.
  • the piston is moved accompanying movement of one latch body 10 of the two forcible moving mechanisms 1 and 1 to the drawn-in position after capturing the striker body S, whereby the damping force of such damper 230 is applied to this movement as well as to the movement of the movable body M.
  • the second urging body 21 is interposed between the cylinder 230a and the latch body 10 connected to the projecting end part of the piston rod 230b outside the cylinder 230a.
  • such second urging body 21 is a compression coil spring 21a with one end of the spring being abutted to an outer end part of the projecting side of the piston rod 230b and the other end of the spring being abutted to a step part 101c formed at a position roughly in the middle of the length direction of the latch base 101 of the latch body 10 positioned on the left side in FIG. 5 with the piston rod 230b being passed through inside.
  • the second urging body 21 can also be a compression coil spring arranged between an inner depth part of the cylinder 230a and the piston inside the cylinder 230a differently from the illustrated example.
  • a resistance-producing body 23 in the damping mechanism 2 is a damper 231 in which a fluid resistance of a fluid inside a stator 231a is applied to a rotation or relative rotation of a rotor not illustrated.
  • damper 231 is referred to as "rotary damper, or the like.”
  • the damping mechanism 2 includes a long and slender first member 24 of which a front end serves as the contact part 20 for contacting with the rear end 100 of one latch body 10 (the latch body 10 on the right side in FIG.
  • both members 24 and 25 are housed movably inside the apparatus base body 3 following the center line y of movement of the latch body 10.
  • a compression coil spring 21a serving as the second urging body 21 is interposed between a rear end 24a of the first member 24 and the rear end 100 of the other latch body 10 of the two forcible moving mechanisms 1 and 1.
  • stator 231a of the damper 231 is fixed to a rear end of the second member 25 so that the rotating shaft of the rotor is arranged in a direction orthogonal to the center line y of movement and in a horizontal direction.
  • a pinion 231b is provided on the other end of the rotor.
  • a rack 24b for engaging with a lower end of the pinion 231b is formed between the front end and rear end 24a of the first member 24.
