Box having foldable and self-locking side walls

摘要

A foldable box includes a floor having a shaft arranged in a base area of an exterior wall area thereof. A guide opening in the fixed exterior wall area and includes a lateral opening section extending from an outside of the fixed exterior wall area inwards. A cam in the base area includes a cam contour which gets into contact with a contact surface of the exterior wall area. When exceeding a boundary angle the shaft is moved inwards. After exceeding the boundary angle a bottom side of the exterior wall is pressed against an internal edge area of the fixed exterior wall area by a force higher than a force by which the bottom side of the exterior wall in the erected vertical position is pressed against a top side of the fixed exterior wall area by the effect of the shaft or the cam.

1. A foldable box comprising:
a floor comprising a fixed exterior wall area extending upwards from the floor in a vertical direction; an exterior wall comprising a shaft arranged at a base area of the exterior wall; a guide opening in the fixed exterior wall area in which the shaft is arranged and which comprises a lateral opening section extending in a basically lateral direction from a exterior side of the fixed exterior wall area inwards; a cam arranged at the base area of the fixed exterior wall area and comprising a cam contour; and a cam opening in the fixed exterior wall area in which the cam is arranged and which includes a contact surface, wherein, when erecting the exterior wall, the cam contour gets into contact with the contact surface to cause a force directed inwards upon the exterior wall so that the shaft is moved inwards in the lateral opening section so that after exceeding a boundary angle, by means of the shaft or the cam, a bottom side of the exterior wall is pressed against an internal edge area of the fixed exterior wall area with a first contact pressing force which is larger than a second contact pressing force, and wherein the bottom side of the exterior wall is pressed with the second contact pressing force against an upper side of the fixed exterior wall area in the upright vertical position by the effect of the shaft or the cam.
