Abstract

Abstract A post for supporting a crash barrier rail is disclosed. The post is a one piece plastics moulding comprising a leg from the upper end of which projects a shoulder having an outer face which is shaped to conform to the inner face of the rail. The post has a flat upper face for driving the post into the ground. A nut is moulded into the post and a passage extends between the outer face of the shoulder and the nut for receiving a bolt by means of which the rail is fixed on the post. A transverse passage may be moulded into the shoulder to provide a ligament joining the lower part of the outerface of the shoulder to the leg. This ligament will yield preferentially when the rail undergoes impact, providing increased elasticity to the barrier. The leg may be provided with a peripheral recess at which the leg will shear preferentially. The post may be moulded of recycled plastics.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 77 words
A post for supporting a crash barrier rail, the post being a one piece moulding of plastics material and comprising a leg and at least one shoulder projecting transversely from the leg with an outer face having a shape which is complemental to the shape of an inner face of the rail so that the inner face of the rail and the outer face of the shoulder fit together to assist positioning the rail on the shoulder.
Claim 2
Dependent Claim 77 words
A post for supporting a crash barrier rail, the post being a one piece moulding of plastics material and comprising a leg and at least one shoulder projecting transversely from the leg with an outer face having a shape which is complemental to the shape of an inner face of the rail so that the inner face of the rail and the outer face of the shoulder fit together to assist positioning the rail on the shoulder.
Claim 3
Dependent Claim 37 words
A post according to claim 1, in which the inner face of the rail comprises a longitudinally extending channel formation and the outer face of the shoulder comprises a protuberance which is received in the channel formation.
Claim 4
Dependent Claim 44 words
A post according to claim 1, in which the inner face of the rail comprises two longitudinally extending channel formations located above the other and the outer face of the shoulder comprises two protuberances which are received one in each of the channel formations.
Claim 5
Dependent Claim 25 words
A post according to claim 3, comprising fastening means for fastening the rail to the post, the fastening means being located between the two protuberances.
Claim 6
Dependent Claim 24 words
A post according to claim 3, comprising a nut for fastening the rail to the post, the nut being moulded into the plastics material.
Claim 7
Dependent Claim 29 words
A post according to claim 5, in which a passage is moulded into the plastics material, the passage extending from the outer face of the shoulder to the nut.
Claim 8
Dependent Claim 14 words
A post according to claim 1, in which the shoulder comprises a transverse passage.
Claim 9
Dependent Claim 34 words
A post according to claim 7, in which below the transverse passage the shoulder has a portion which is of diminished stiffness so that it will readily yield elastically when the rail is impacted.
