Hinge for a panel door, in particular for a cooling cupboard

1. A hinge for a panel glass door for sealing a space, wherein the hinge comprises:

a sill/lintel-attachment part defining a longitudinal axis,

two mutually connectable clamping parts for clamping a panel in between them along an edge of the panel, and defining between them a mirror plane,

a pivot pin fixed to one of the sill/lintel-attachment part and the clamping parts, which connects, on one end, to the sill/lintel-attachment part and, on the other end, to the clamping parts in such a manner that the sill/lintel-attachment part and the clamping parts can pivot with respect to one another, wherein the mirror plane of the clamping parts extends radially from a pivot axis of the sill/lintel-attachment part and the clamping parts,

tensioning parts which force the sill/lintel-attachment part into a neutral position in which the sill/lintel-attachment is in equilibrium with respect to the clamping parts, wherein, in the neutral position, the mirror plane of the clamping parts and the longitudinal axis of the sill/lintel-attachment part are at an angle of 5-15 degrees, and

a lubrication channel, the lubrication channel running from a lubrication opening on one of the clamping parts to a top part of the pivot pin when the hinge is assembled.

2. The hinge of claim 1 , wherein the tensioning parts engage with the pivot pin.

3. The hinge of claim 1 , wherein the pivot pin is non-rotatably connected to the sill/lintel-attachment part.

4. The hinge of claim 1 , wherein the tensioning parts are positioned opposite one another, the pivot pin comprises mutually opposite stops for the tensioning parts, and the pivot pin is non-rotatably connected to the sill/lintel-attachment part, wherein a line connecting the opposite stops is parallel to the mirror plane of the clamping parts.

5. The hinge of claim 1 , wherein the hinge is furthermore provided with a seat defined by a distance between the clamping parts, wherein the pivot pin is rotatably held in the seat, and the seat is provided with the tensioning parts, on which seat the tensioning parts have a line of action which, in the neutral position, is parallel to the neutral position.

6. The hinge of claim 1 , wherein the pivot pin is made of a hardened steel material.

7. The hinge of claim 1 , wherein the seat is provided with an opening for the tensioning parts, the tensioning parts comprise a stop, coil spring and a fixation element, the opening being provided on its inside surface with a screw thread for engagement with the fixation element over only a part of the length of the opening.

8. A cooling cupboard provided with at least one glass door, at least two opposite hinges according to claim 1 attached to the glass door, and a stop for the glass door, wherein the stop is positioned to keep the glass door in a position in which an angle between the longitudinal axis and the mirror plane is less than the angle between the longitudinal axis and the mirror plane in the neutral position, and the neutral position of at least one hinge is inwards beyond the stop.

9. The hinge of claim 2 , wherein the tensioning parts are urged into contact with the pivot pin along a direction that is perpendicular to an axis of the pivot pin.
