Definitions

  • the invention relates to a motorized closure for devices with a door that a has circumferential elastic seal.
  • the invention has for its object to facilitate operation and to ensure a uniform closing pressure regardless of the quality and wear of the seal.
  • This object is achieved in a motorized closure of the type mentioned in that a door-side block, which has a transverse bore, is immersed in a gripper which consists of two pliers halves connected by a bearing, between which a slotted hole and a motor-driven control slide is mounted is, which in one end position releases the pliers opening and blocks these pliers and the block in the other, so that the motor can pull the door against the housing with adjustable force.
  • Fig. 1 denotes a block which projects between the halves 2a, 2b of a gripper 2.
  • the parts 2a, 2b represent two-armed levers which are connected to one another via molded-on bearing blocks 2a1, 2b1 and a bolt 3.
  • a control slide 4 between the bearing blocks 2a1 and 2b1, the elongated hole 4a of which extends over the bolt 3.
  • a light coil spring 5 is clamped, which compresses the gripping pliers 2 at the left end.
  • the actual gripping elements are truncated cones 2a2 and 2b2, which fit into a recess 1a in the block 1.
  • the pliers 2 snap into place, as shown in Fig. 2 .
  • the block 1 is held with a force that is predetermined by the characteristics of the spring 5.
  • Fig. 4 it is shown how the unit consisting of the clamp 1 and gripper 2 was pulled to the right with the aid of the control slide 4 in order to firmly press the door seal.
  • the contact pressure is determined by the motor, which has an adjustable switch-off torque.
  • the opening of the cabinet is as follows: If the motor is reversed by an opening pulse, the described unit moves to the left until the pressure exerted by the seal is balanced. The control slide 4 then runs into its left end position, which is drawn in FIG. 2 . In this unlocked position, the door can be easily opened with the block 1, as shown in FIG. 1 .
  • 5 shows the pliers half 2b in a top view. The truncated cone 2b2 can be seen at the bottom, the bearing blocks 2b1 in the central region and pins 2b3 at the upper edge, which receive two identical coil springs.
  • this pull rod 6 can be seen in different operating states.
  • the left end of the rod is connected to the control spool 4 via the holes 6a, and the right end is coupled to a geared motor unit 7 shown in FIG. 10 via an angled slot 6b.
  • the driven wheel 8 of this unit carries an eccentric pin 9 which slides in the slot 10a of a link 10.
  • this link has a coupling pin 10b which slides in the slot 6b. Slot and coupling pin serve as an emergency release for the closure.
  • Fig. 8 shows the arrangement in the state of the emergency release
  • Fig. 9 shows the position of the parts with the door closed.
  • the rod 6 can move to the left and the pliers 2 release the block 1. If the door is to be closed after an emergency release, the motor must first receive an opening impulse. The setting 10 then moves to the left until the pin 10b assumes the latching position in the angled slot 6b. The rod 6 either falls down due to its own weight, or the engagement is effected by a spring. In Fig. 10 , the rod 6 and the backdrop 10 assume the left end position, in which the door is open or prepared for opening. When the motor 13 starts in the closing direction, the driven gear 8 is moved in the direction of the arrow 12 via the gears 14, 15, 16.
  • the eccentric pin 9 pulls the link 10 with the rod 6 to the right until a certain closing force is reached and the state corresponds to FIG. 9 .
  • the angle of rotation of the wheel 8 can be between 100 and approximately 170 °. By fine adjustment, an angle between 150 and 170 ° will be preferred, because then a greater closing force can be achieved with a smaller motor torque.
  • the gears 14, 15 are designed as worm gears, the drive is self-locking.
  • a sensor for the current consumption causes the motor to switch off when a desired closing force is reached.
  • the locking command for the geared motor can come from a door contact, a button on the cabinet or in the foot area or from a program control.
  • the door lock described is intended to be used in hot appliances or other technical devices such as centrifuges. It is particularly advantageous that the operator has his hands free.
  • the maintenance intervals for the system are very long because the gripping pliers, which are exposed to heat or a special atmosphere, have no sensitive parts and because the aging seal is always pressed with constant closing force.
