Hinge for a packaging box or the like
A hinge for a packaging or cargo box or the like, having a first and a second hinge leaf, the second hinge leaf has a first bushing and a second bushing located at a distance therefrom, between which a bushing of the first hinge leaf can be rotated about a mutual hinge axis. An axial tube is rotationally fixed to the bushing of the first hinge leaf and is pivot-supported in the bushings of the second hinge leaf. A torsion spring is disposed in the axial tube and attached to one end of the axial tube. A torque support connects the other end of the torsion spring to the second hinge leaf in a rotationally fixed manner. A damper for the hinge movement is connected to the second hinge leaf and the axial tube. In a cylindrical hollow space of an outer opening, formed by the three bushings ( 65 a , 65 b , 65 c ), the damper ( 56 ), the axial tube ( 53 ) containing the torsion spring ( 58 ), and the torque support ( 54 a ) are inserted successively starting at the second bushing ( 65 b ) of the second hinge leaf ( 52 ), and the torque support ( 54 a ) is prevented from rotating and from being axially displaced in the second bushing ( 65 b ) by a safety device ( 54 d , 68 a , 70, 72 ).
1. A hinge for a cargo box or other article, comprising:
a first and a second hinge leaf,

a damper for hinge motion connected to the second hinge leaf and the axle tube, a cylindrical hollow space is formed by the three bearing bushings ( 65 a , 65 b , 65 c ) together, wherein the damper ( 56 ) has smaller outside dimensions than inside dimensions of the second bearing bushing ( 65 b ) and the bearing bushing ( 65 c ) of the first hinge leaf ( 51 ) so that the damper ( 56 ) is slidable through the second bearing bushing ( 65 b ) and the bearing bushing ( 65 c ) of the first hinge leaf ( 51 ), and the damper ( 56 ), the axle tube ( 53 ) containing the torsion spring ( 58 ), and the torque converter support ( 54 a ) are inserted successively from an outer opening of the second bearing bushing ( 65 b ) of the second hinge leaf ( 52 ) into the cylindrical hollow space from a same side of the hinge so that an end of the first bearing bushing on an axially opposite side of the hinge can remain closed or inaccessible, and the torque converter support ( 54 a ) in the second bearing bushing ( 65 b ) is prevented from rotation and axial displacement by a securing device ( 54 d , 68 a , 70 , 72 ).
2. The hinge according to claim 1 , wherein the first and the second bearing bushing ( 65 a , 65 b ) project approximately equally as far in an axial direction past the second hinge leaf ( 52 ).
3. The hinge according to claim 1 , wherein the first bearing bushing ( 65 a ) of the second hinge leaf ( 52 ) is closed on a side facing away from the second bearing bushing ( 65 b ).
4. The hinge according to claim 1 , wherein the damper ( 56 ) has a radial damping vane that rotates in a chamber of a damper housing ( 56 a ) filled with viscous damping material, and the damper housing is locked in rotation with the first bearing bushing ( 65 a ) of the second hinge leaf ( 52 ).
5. A hinge for a cargo box or other article, comprising:
a first and a second hinge leaf,
the second hinge leaf has a first bearing bushing and a second bearing bushing set apart from the first bearing bushing, a bearing bushing of the first hinge leaf is rotatable about a common hinge axis between the first and second bearing bushings,
an axle tube locked in rotation with the bearing bushing of the first hinge leaf and is supported in the bearing bushings of the second hinge leaf so that it rotates,
a torsion spring arranged in the axle tube and mounted with one end on the axle tube,
a torque converter support ( 54 a ) that locks the other end ( 58 ) of the torsion spring in rotation with the second hinge leaf ( 52 ), and
a damper for hinge motion connected to the second hinge leaf and the axle tube, a cylindrical hollow space is formed by the three bearing bushings ( 65 a , 65 b , 65 c ) together, wherein the damper ( 56 ), the axle tube ( 53 ) containing the torsion spring ( 58 ), and the torque converter support ( 54 a ) are inserted successively from an outer opening of the second bearing bushing ( 65 b ) of the second hinge leaf ( 52 ) into the cylindrical hollow space, and the torque converter support ( 54 a ) in the second bearing bushing ( 65 b ) is prevented from rotation and axial displacement by a securing device ( 54 d , 68 a , 70 , 72 ), wherein the securing device comprises a securing element that engages through at least one opening ( 70 ) in the second bearing bushing ( 65 b ) in a peripheral groove ( 68 b ) of a retaining ring ( 68 ) that is locked in rotation with the torque converter support ( 54 a ).
6. The hinge according to claim 5 , wherein the securing element comprises a spring clip ( 72 ) that engages via two openings ( 70 ) in the second bearing bushing ( 65 b ) in the peripheral groove of the retaining ring ( 68 ).
7. The hinge according to claim 5 , wherein for the rotational locking between the torque converter support ( 54 a ) and the retaining ring ( 68 ), the torque converter support ( 54 a ) has a cylinder peg ( 54 d ) that has external teeth and that engages in an opening ( 68 a ) of the retaining ring ( 68 ) with internal teeth, and the retaining ring ( 68 ) has an outer periphery with external teeth that engage in internal teeth ( 69 ) in the second bearing bushing ( 65 b ) of the second hinge leaf ( 52 ).
