Definitions

  • the present invention relates to a device for opening or closing a sliding door displaceable along a wall, said door having a drve cylinder with a piston mounted on the wall or on another fixed point, the stroke of which piston is smaller than the path to be travelled by the door during opening or closing, and having at least two projections mounted on the door with one of which a support mounted on the drive piston rod coacts over part of said path.
  • the drive unit In order to transmit sufficient energy of movement'to the door it is necessary to give ample dimensions to the drive cylinder. Particularly in a'door having a high weight of its own, the drive unitshould be very sturdy, while it should be borne in mind that there will be an increasing frictional resistance of the door when the guide structure becomes older.
  • Afurther'drawback of this prior drive device is that if, the door is unexpectedly stopped, for instance by some obstacle or other, before the full pathhas been travelled, and has thereby, come beyond the reach of the support, the doorcan be moved farther only by manual effort.
  • the object of the present invention' is to remove that when the sliding door is in the position of the door shown in FIG. 1.
  • FIG. 8 is a vertical sectional view on enlarged scaleof the-spring-biased pin.
  • FIG. 1 a sliding door 1, which can be displaced along a guide part 2, is drawn in the position in which an opening 3 in a wall 4 is covered.
  • the door 1 can be moved by a drive unit 5, for example a pneumatic cylinder with a piston and a piston rod 5 a, which is provided on the free end with support 6 and a pin 7, the position of which is determined by the shape of a profiled guide 8 havingbevelled ends 9 and 10.
  • the dragger pin 7 is urged upwards by means of a spring 7a, shown in FIG. 8, the upward urging being to a position as shown in FIGS. 3-6.
  • a switch 14 is mounted on the wall 4, while the door is provided with contact elements 15, 1 6, which coact with the switch 14 during the opening of the door.
  • a switch 17 also mounted on the wall 4 coacts during the closing of the door with two other'contact elements 18 and 19 mounted on the door.
  • the switching combination 14, l5,andl6 and also l7, l8 and 19 can consist both of contactless and of mechanically operated switches.
  • cording to a preferred embodiment of the invention, with a spring-biased pin which is slidable transverse to the direction of displacement of the piston and catches behind one of the projections in an extended position against spring pressure.
  • the position of the pin with respect to the support can be determined by a stationary profiled guide extending over the outreach of the support.
  • control device may have a switching means with contacts, of which part is mounted on the door and part on the wall.
  • FIG. 1 shows a front elevational view of a sliding door according to the invention in closed position
  • FIG. 2-5 show the upper part of the sliding door v shown in FIG. 1 in different positions during the opening of the door;
  • FIG. 6 is the same view of the sliding door in entirely opened position and FIG. 7 is a circuit diagram of the control device of the present invention, the circuit condition depicted being from the two end positions, as well as a changeover. switch 22, operated by the doorv in the two end posi: tions. i f
  • 'Said switches are connected with an electrically operable air valve 23 having. two alternative axial positions. In the axial position shown, the valve 23 enables air to be introduced into the drive motor 5. to the right of the piston on piston rod Sa'and air to be vented from the left hand end of the drive motor 5. In the other axial position, air is introduced to the left of the piston and air to the right of the piston is vented from the drive motor 5.
  • thedoor l is subsequently displaced further the opening direction.
  • the number of projections located between the end projections 11 and 13 need not be restricted to one, but may also be more than one projection with which the door can be driven each time over part of the total path of the door in the manner described above.
  • a device for opening and closing a door which is guidingly supported on a wall for sliding movement in a travel path along said wall between full open and full closed positions comprising a drive unit including a cylinder, a piston slidable in said cylinder, and a rod connected at one end to said piston, said cylinder being fixedly mounted with respect to the travel path of said door in a position wherein said piston and rod move in forward and return strokes in a course parallel to the travel path of said door adjacent the upper part of said the pin 7 door, the stroke of said piston and rod being less than the travel of said door when said door is moved between full closed and full open positions and vice-versa, said door'having at least three projections fixed to the upper part thereof, a support carried on the other end of said piston rod, a spring biased pin mounted on said support, said pin being disposed for sliding movement transverse to the travel path of said door and normally being urged by said spring in a direction away from said door travel path, fixed guide means, said pin being engaged with said guide means, said
