Hinge part that is attached to the lower part of a freezer, for example. The fixed hinge part "consists only of a tab 2> one with this from one piece "existing bearing pin 3» which is opposite Holding surfaces 4 »5 for the compensation mechanism "and a stationary on the trunnion 3. Link 6. The quay surfaces 4, 5 of the bearing journal 3 are slightly conical «The same applies to * the corresponding hole in the connecting link 6, so that a backlash-free engagement with the components of the compensation and locking mechanism is guaranteed, as will be explained below, .on the link is articulated "«

A swing arm 8 is rotatably mounted on the connecting link 6 by means of a hinge pin 7 and a swivel arm Io is rotatably mounted on the i-bow hinge part 1 by means of a further hinge pin 9. The pig carries 8 on her ,,: oiiteror. Hr.- <5e Eiren other G elenkbolzen wad 11 with a cam 12 and a Hachspannkurve 13 is provided. The swivel arm 1.0 is provided at its free end with an elongated hole 14 for mounting the hinge pin H, which allows displacement of the engaging lever arm. The upper end of a spring guide rod 15 is also mounted on the G-pivot pin 11 of the rocker arm 8.

Via the rocker arm 8 and the leather guide rod under the guidance of the swivel arm Io, the force of a designed as a helical spring compression spring 16 on the fixed so-hinge part, namely the connecting member 6, the bearing pin 3 and the bracket 2, transferred.

009829/0390

The compression spring 16 is supported at its upper end

a correspondingly widened paragraph lOder spring guide rod 15 and at its lower end via a plate 18 on a guide tube 19, which is externally threaded is provided and with the interposition of a rocker 2o, which is accordingly provided with a thread on the inside, rests on a cutting edge bearing 21 in the wing hinge part 1. By rotating the guide tube 19, the tension of the compression spring 16 can be adjusted to the desired cover torque before installation can be set.

To describe the mode of operation, reference is made to Figure 1, which the wing in closed State shows. The spring 16 presses over the spring guide βtange 15 »the hinge pin 11 and the rocker arm 8 on the Hinge pin 7 on the connecting link 6 and thus on the fixed hinge part. The hinge pin 11 is guided in the elongated hole 14 through the swivel arm Io. To close of the wing, the rocker 8 slides with its control cam 12 on the hinge pin protected by a roller 22 along to the position shown in FIG. The shape of the control cam 12 ensures that during the closing movement the hinge pin 11 maintains its position in the elongated hole 14 of the pivot arm Io. Only when the wing comes close has reached its closed position, the hinge pin 11 is pressed by the spring Ig into the opposite end shown in FIG. The hinge pin 11 therefore stops during the pivoting movement of the door its greatest possible distance from the roller 22 or the hinge pin 9. This is the distance between the hinge pin and 9 smaller than the distance of the bearing pin 3 from the hinge pin 7. The distance can, however, with a corresponding Change of the spring characteristics also designed differently

will. With a corresponding selection of the spring characteristics, the two mentioned distances can also be approximately the same. So when the wing 1 is pivoted through a certain angle, the pivot arm 10 pivots at the same time through a larger angle in the embodiment shown. The interaction of the spring characteristics and the acting lever arm results in a change in the torques according to the cosine function.

The control cam 12 of the rocker 8 is followed by a flat clamping cam 13. As can be seen from Figure 1, So with the wing closed, the spring 16 presses the spring guide rod 15 on the roller 22 and tries to Swing arm 8 to move to the left. In doing so, it generates a torque in the wing, which acts on the wing's seal presses. With a corresponding design of the Haohepann curve 13 At the same time, the hinge pin 11 is divided into an inner line pressed in slot 14. Depending on the shape of the tensioning curve, this end division is more or less achieved. After that, however, the position of the rocker and thus the size of the contact pressure of the wing on its seal depends. Depending on the selected shape of the tensioning curve, the contact pressure of the wing on the sealing of the lower part is thus E.g. a freezer be larger or smaller. The wing can also be from part of its own weight be relieved.

If the wing is now opened by about 15 °, ao slides the rocker 8 with the Hachspannkurve 13 and the control cam 12 bo on the roller 22 along that the hinge pin 11 is pressed into the furthest position from the roller 22 at the other end of the elongated hole 14 and thus with a maximum The pivot arm pivots around the hinge pin 9 and makes the wing weightless in every position.

By the control cam 12 it is achieved that the pivot arm 10 always has maximum effective length, since the legs Hinge pin 11 assumes its outer position in slot 14.

As can be seen from FIG. 1, when the wing is closed, the rocker 8 is carried along to such an extent that the roller 22 on the inside of the rocker 8 on a sowing 23 is present. By appropriately shaping the projection 23, it is possible to achieve that the end position of the wing at its contact pressure is limited at will.

When the sash is open, the opening angle may be large or be small, the animal joints take 3 »7» 9 »11 one Position to each other in which the axis of the pivot pin 9 lies outside a triangle that is formed from the rest of the articulation arch. The pressure of the spring 16 acts while on the Federführungestaage 15, the Gelemkboleen 11, the rocker 8 on the articulated arch 7 and acts dea Gewioht towards the flight. When the wing is closed, as in Figure 1 shows, the undercut causes the rocker θ ia area the Hachepann curve 13 in connection with the elongated hole 14- of the swivel arm Io is a deflection of the spring force, on the other hand the hinge pin 9 with the hollow 22 so that its axis lies within the triangle that is formed from the three remaining hinge pins. The Federdruok now works in the other directions of rotation and the wing is not only with its own weight but nooh with the help of the spring force on the seal of the container pressed.

In order to limit the opening path of the sash (generally one chooses a largest opening angle Ton 90 °) the connecting member 6 has the bearing pin 3 on its

009829/0390

overlapping part 35 on a certain Durohmesser. In the open position of the hinge, you swing arm 8 rests against part 35 with its stop 23 and thus prevents further opening of the paddle. Through suitable Choosing the diameter of the part 35, it is up to you to determine the opening angle.

The storage of the compensation and locking mechanism within the pivoting hinge part 1 is in Pigur shown. After that, the U-shaped housing of the adjustable Hinge part 1 in the side walls 25 »26 bearing bores 271 28, the bearing surfaces of which by after inwardly directed, annular material settings 29 are widened. The connecting member 6 is on the one hand with a bolt-like one engaging in the storage container 27 Approach 31 and, on the other hand, provided with a recess 32. In the recess 32 of the connecting member 6 engages a bearing bush 33, which at its end in the bore 28 of Side surface 26 of the housing is mounted. Between the side surface of the connecting member 6 facing the G-housing wall 26 and the annular material setting 3o of the same A peder ring 34 is arranged on the side wall 26 of the housing on the bushing 33. The journal 3, which through reaches through the bores of the components shown in Pigur 2, is provided with a thread at its protruding end on the inside of the paddle. As a result of the conical design of the holding surfaces 4, 5 of the journal 3 can eämtlicht components of the storage be braced against each other by means of a cutter from the inside on the bearing pin.
