1. A foldable modular spaceframe comprising:
a polygonal front frame having at least one holding structure;
a rigid and planar first truss frame, said first truss frame comprising at least first and second hinge arms and a first longitudinal connector beam, whereby said first truss frame is hingedly attached with the first and second hinge arms to the front frame at one end of the first and second hinge arms, each of the hinge arms being attached at said one end to the front frame towards opposite edges of the front frame, whereby said first connector beam rigidly connects other ends of the hinge arms opposite to the one end of the hinge arms, where the other ends of the hinge arms are not attached to the front frame,
a first hinge connection connected to the first and second hinge arms, around which the first truss frame hinges, and forming a first hinge axis, that is parallel to the first connector beam;
a first locking element on a first end of said first connector beam;
a rigid and planar second truss frame, said second truss frame comprising at least third and fourth hinge arms, and a second longitudinal connector beam, whereby said second truss frame is hingedly attached with the third and fourth hinge arms to the front frame at one end of the third and fourth hinge arms, each of the hinge arms being attached at said one end to the front frame towards opposite edges of the front frame, whereby said second connector beam rigidly connects other ends of the hinge arms opposite to the one end of the hinge arms, where the other ends of the hinge arms are not attached to the front frame;
a second hinge connection connected to the third and fourth hinge arms, around which the second truss frame hinges, and forming a second hinge axis, parallel to the first hinge axis, and whereby other ends of the third and fourth hinge arms opposite to the one end of the hinge arms, where the other ends of the hinge arms are not attached to the front frame, detachably interlock with the locking elements of the connector beam of the first truss frame,
a second locking element on a first end of said second connector beam, the first end of said second connector beam facing to said first end of said first connector beam and said second locking element facing to said first locking element;
whereby said other ends of the hinge arms comprise locking elements for said detachable interlocking;
wherein the first hinge axis of the first truss frame lies in a first plane, and the second hinge axis of the second truss frame lies in a second plane, where both said first frame and said second frame are parallel to the front frame, thereby allowing the first and the second truss frame to be folded towards the front frame to a substantially parallel position to said front frame,
and where said first hinge connection moves said first connector beam in a first direction, and said second hinge connection moves said second connector beam in a second direction opposite to the first direction, until the first connector beam is collinear to the second connector beam, and where the first locking element on the first connector beam connects to the second locking element on the second connector beam when the first connector beam is collinear to the second connector beam.
