Definitions

  • the invention relates to a spring-operated hinge with a spring tensioned when the door is opened, the legs of which transmit the closing forces from the hinge flap to the hinge bracket.
  • Hinges have been manufactured and sold for many years, the parts of which are connected by a spring.
  • the spring is tensioned when the door is opened. Your potential energy is used to accelerate the door in the closing direction.
  • Such hinges are preferably used on doors for refrigerated counters, which are held in the closed position by magnetic strips.
  • the known spring hinges have the disadvantage that the door impinges on the closing strips with momentum and can spring back, so that there is no secure closure without holding magnets. It is also disturbing that the door does not remain in the open position by itself, so that the user must keep the door open against the force of the closing spring.
  • the object of the invention is to provide a hinge which automatically keeps the door open and initiates the closed position after overcoming a dead center. Above all, however, it should have a sufficient closing torque in the closed state.
  • Fig. 1 denotes the hinge bracket, 2 of the hinge tabs, 3 an upper cap, 4 a lower cap, 5 an upper and 6 a lower spring. Parts 1 and 2 are connected to one another by a hinge pin 7.
  • a set screw 8 (Fig. 1 a) is used to bias the springs 5, 6.
  • 3a-c show how the springs 5, 6 mounted in the hinge flap 2 act on the hinge bracket 1.
  • control cams 1 e, 1 f are formed, on which the outer spring legs 5a, 6a rest.
  • Fig. 3a shows the closed position
  • Fig. 3b and 3c intermediate positions when opening
  • Fig. 3 shows an extreme open position after an angular movement of almost 180 °.
  • the hinge When the door is closed, the hinge initially behaves indifferently between 180 ° and approximately 60 °. The springs maintain their deflection state and do not exert any torque on the door. In the last third of the closing process (transition from Fig. 3b to Fig. 3a), the springs 5, 6 exert a strong torque on the hinge bracket. The door closes and is held in the closed state by pressing the seals.
  • Fig. 4 shows the hinge flap 2 from the rear.
  • stiffening ribs 2c, 2d and the receiving pockets 2e, 2f for the springs 5 and 6 can be seen.
  • the longitudinal section AB is shown in FIG. 5.
  • FIG 6 shows the cross section CD in the region of the fastening hole 2a.
  • Fig. 7 shows the side view.
  • FIG. 8 is a sectional view along the line EF in FIG. 5.
  • a slot 2g can be seen in which the legs of the springs 5, 6 are immersed.
  • a threaded pin is inserted into a threaded hole 2h, which allows the preload of the springs to be set.
  • the opening 2i receives the hinge pin 7.
  • FIG. 9 shows a section along the line GH in FIG. 5.
  • FIG. 10 shows the front view of the threaded tab 2 with the fastening holes 2a, 2b.
  • the slots 2j, 2k serve for the passage of the spring legs 5a, 6a.
  • Fig. 11 shows the front view of the hinge bracket 1 again.
  • the end shields are designated 1 a, 1 b. Holes 1 c, 1 d serve for attachment. Control cams 1e, 1f are formed on the shields 1a, 1.
  • FIG. 11 shows the hinge bracket 1 from above.
  • Fig. 12 shows the partially cut side view of the hinge bracket 1.
  • the hole 1 g receives the hinge pin.
  • Fig. 13 three views of the cap (Fig. 1, 2) are shown.
  • FIG. 13a The view from below is shown in FIG. 13a. It has webs 3a, 3b which engage in corresponding grooves on the bearing block. With 3c, 3d are cutouts for weight reduction.
  • the hinges described are preferably intended to be used in all types of refrigeration cabinets. Installation is easy and can be carried out without any problems.
  • the caps shown in Fig. 3 are pushed onto the built-in hinge bracket with the door open. Since they cannot be removed when the door is closed, they serve as a securing means for hinge pin 7. The caps not only make it more difficult to break open the door, they also fulfill a design function.
