Door hinge
A door hinge has a first leaf assembly, a second leaf assembly and a link assembly for pivoting of the first leaf assembly on the second leaf assembly between an open position and a closed position. This link assembly in turn has a first hinge link and a second hinge link pivoted about a connecting axis on the first link. The first hinge link is formed with a contact face that in the open position flatly engages a contact face of the second hinge link. This the first contact face also is formed with a projection that in the open position engages complementarily in a recess formed in the second hinge link.
1. A door hinge comprising:
a first leaf assembly, a second leaf assembly and a link assembly for pivoting of the first leaf assembly on the second leaf assembly between an open position and a closed position, the link assembly comprising
a first hinge link connected to the first leaf assembly so as to be pivotable about a first hinge axis, the first hinge link being pivotal about a second hinge axis positively guided on the second leaf assembly, and
a second hinge link pivoted about a connecting axis on the first link, the first hinge link having a contact face that in the open position flatly engages a contact face of the second hinge link, the first contact face also having a projection that in the open position engages complementarily in a recess of the second hinge link, the second hinge link being connected to the first link assembly so as to pivot about a third hinge axis that is positively guided on the first leaf assembly, the second hinge link being connected to the second leaf assembly so as to pivot about a fourth hinge axis.
2. The door hinge according to claim 1 , wherein the second hinge axis is guided on the second leaf assembly in a link guide.
3. The door hinge according to claim 1 , further comprising:
a pivot link carrying the second hinge axis on the second leaf assembly.
4. The door hinge according to claim 3 , wherein the pivot link in the open position lies flat against an outer face of the second hinge link.
5. The door hinge according to claim 4 , wherein the outer face forms with the second contact face an angle between 90° and 135°.
6. The door hinge according to claim 4 , further comprising:
another pivot pin connecting the pivot link to the second leaf assembly and coaxial to a pivot axis of the other pivot pin, the outer face extending in a plane extending through the axis of the other pivot pin.
7. The door hinge according to claim 3 , wherein the pivot link in the closed position bears with a back face against a casing of the second leaf assembly.
8. A door hinge comprising:
a first leaf assembly, a second leaf assembly and a link assembly for pivoting of the first leaf assembly on the second leaf assembly between an open position and a closed position, the link assembly comprising
a first hinge link,
a second hinge link pivoted about a connecting axis on the first link, the first hinge link having a contact face that in the open position flatly engages a contact face of the second hinge link, the contact face having a projection that in the open position engages complementarily in a recess of the second hinge link, and
a hinge pin connecting the first hinge link and the second hinge link and centered on the connecting axis, the first contact face extending in a plane passing through the hinge pin.
9. A door hinge comprising:
a first leaf assembly, a second leaf assembly and a link assembly for pivoting of the first leaf assembly on the second leaf assembly between an open position and a closed position, the link assembly comprising
a first hinge link, and
a second hinge link pivoted about a connecting axis on the first link, the first hinge link having a contact face that in the open position flatly engages a contact face of the second hinge link, the first contact face also having a projection that in the open position engages complementarily in a recess of the second hinge link, the first hinge link is being T-shaped with a horizontal crosspiece and a central leg member, the second hinge link being O-shaped with two vertical members and two horizontal members surrounding the central leg member, the pivot link being C-shaped.
10. The door hinge according to claim 9 , wherein the projection is formed on the leg member of the first hinge link.
11. The door hinge according to claim 9 , wherein the recess is formed on one of the vertical members and extends over not more than the half of a vertical height of the second hinge link.
