Abstract
Abstract A palisade comprises visible or wall surfaces disposed on opposing sides and intermediate end faces. One of the end faces is provided with a projecting convex head, while the other end face comprises a correspondingly formed concave receptacle for the head. When forming a palisade wall, the head of a palisade can engage in the receptacle of a neighboring palisade such that the head substantially completely fills the receptacle. To be able to bend neighboring palisades relative to one another over a large angle and to increase the design possibilities of a palisade wall, the head and the receptacle are disposed eccentrically on the respective end face and preferably in the corner region between the end face and the associated visible or wall surface.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
131 words
A palisade with visible or wall surfaces disposed on opposing sides, and lateral end faces, wherein one of the end faces is provided with a single projecting convex head portion and the other end face is provided with a single concave receptacle portion, and wherein the head and the receptacle engage with one receptacle or head of a neighboring palisade when forming a palisade wall, such that the head substantially completely fills the receptacle, wherein the head and the receptacle are eccentrically disposed in a same direction on the respective end face, and wherein said head projects outwardly from the planes of one of said visible or wall surfaces and one of said end faces end wherein said palisade comprises a unitary concrete structure formed with said head and said receptacle.
Claim 2
Dependent Claim
131 words
A palisade with visible or wall surfaces disposed on opposing sides, and lateral end faces, wherein one of the end faces is provided with a single projecting convex head portion and the other end face is provided with a single concave receptacle portion, and wherein the head and the receptacle engage with one receptacle or head of a neighboring palisade when forming a palisade wall, such that the head substantially completely fills the receptacle, wherein the head and the receptacle are eccentrically disposed in a same direction on the respective end face, and wherein said head projects outwardly from the planes of one of said visible or wall surfaces and one of said end faces end wherein said palisade comprises a unitary concrete structure formed with said head and said receptacle.
