Hinge joint device for the support of a sign post or the like comprising - a first element for the junction with a foundation for the sign post, - a second element for the junction with a base section of the sign post, whereby the second element has a substantially tubular shape that has an inner receiving part for receiving a resilient element and - a hinge junction that connects the first element with the second element with which the second element is movable with respect to the first element between a first angular position and a second angular position, whereby the first angular position is a position for which the first element has substantially the same orientation than the second element and whereby the second angular position is an inclined position of the second element with respect to the first element, whereby the hinge joint device comprises a prestressed return element that is configured to force the first element and the second element into the first angular position, whereby the prestressed return element comprises the resilient element, which comprises a disc spring or a series of disc spring assemblies, and a deforming element for the interaction with the resilient element for the elastic deformation of the resilient element during a movement between the first angular position and the second angular position, whereby the resilient element has a first end, a second end turned away from the first end and a end-to-end hollow space that extends between the first end and the second end, whereby the inner receiving part has a supporting area for the first end of the resilient element, whereby the deforming element is placed through the end-to-end hollow space of the resilient element and comprises a head that bears on the second end of the resilient element, whereby the head in the second angular position is nearer to the supporting area than in the first angular position and whereby the hinge joint device comprises a chain with a multitude of rings (31, 32, 33), whereby a first ring is connected to the first element and the second ring to the deforming element. - a first element for the junction with a foundation for the sign post, - a second element for the junction with a base section of the sign post, whereby the second element has a substantially tubular shape that has an inner receiving part for receiving a resilient element and - a hinge junction that connects the first element with the second element with which the second element is movable with respect to the first element between a first angular position and a second angular position, whereby the first angular position is a position for which the first element has substantially the same orientation than the second element and whereby the second angular position is an inclined position of the second element with respect to the first element, whereby the hinge joint device comprises a prestressed return element that is configured to force the first element and the second element into the first angular position, whereby the prestressed return element comprises the resilient element, which comprises a disc spring or a series of disc spring assemblies, and a deforming element for the interaction with the resilient element for the elastic deformation of the resilient element during a movement between the first angular position and the second angular position, whereby the resilient element has a first end, a second end turned away from the first end and a end-to-end hollow space that extends between the first end and the second end, whereby the inner receiving part has a supporting area for the first end of the resilient element, whereby the deforming element is placed through the end-to-end hollow space of the resilient element and comprises a head that bears on the second end of the resilient element, whereby the head in the second angular position is nearer to the supporting area than in the first angular position and whereby the hinge joint device comprises a chain with a multitude of rings (31, 32, 33), whereby a first ring is connected to the first element and the second ring to the deforming element.
