Abstract

Abstract A shock absorber arrangement for use as a fender for ships and comprising a fixed plate mountable on a harbour wall and a movable plate connected thereto by an array of resilient shock absorbers of known type. The array of shock absorbers are coupled in three pairs to three points of the fixed plate, the three points lying at the apices of an equilateral triangle, and each pair of shock absorbers forms an isosceles triangle the base of which is formed by the fixed plate; the angle of the vertex of the isosceles triangle is greater than the angle of the other two apices. The three vertices of the pairs of shock absorbers are coupled to points lying at the apices of an equilateral triangle on the movable plate; the two equilateral triangles are positioned angularly displayed from one another by 60* and the two plates lie in substantially parallel planes when the arrangement is in a rest position.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 232 words
A resilient shock absorber arrangement attachable to a harbour wall or like fixed point to absorb shocks generated by impacts of ships against the sides thereof during docking maneuvres, of the type comprising: a first plate attachable to said fixed point, a second plate presenting an abutment surface for ships to strike against, resilient elongate shock absorber means interconnecting said first plate and said second plate, said shock absorber means being connected in three pairs such that the axes of the shock absorber means of each pair form an isosceles triangle, the base of which is formed by the said first plate and the vertex of which has a greater angle than the angle of the base apices, said three pairs of shock absorber means lying in three planes which define a first substantially equilateral triangle where they intersect the said first plate, one side of said first substantially equilateral triangle being substantially horizontal, the three vertices of said isosceles triangles formed by said three pairs of shock absorber means being connected to said second plate at three points defining a second substantially equilatral triangle one side of which is substantially horizontal, the substantially horizontal side of one of said first and second substantially equilateral triangles forming the upper side thereof, and the substantially horizontal side of said other of said first and second substantially equilateral triangles forming the lower side thereof.
Claim 2
Dependent Claim 232 words
A resilient shock absorber arrangement attachable to a harbour wall or like fixed point to absorb shocks generated by impacts of ships against the sides thereof during docking maneuvres, of the type comprising: a first plate attachable to said fixed point, a second plate presenting an abutment surface for ships to strike against, resilient elongate shock absorber means interconnecting said first plate and said second plate, said shock absorber means being connected in three pairs such that the axes of the shock absorber means of each pair form an isosceles triangle, the base of which is formed by the said first plate and the vertex of which has a greater angle than the angle of the base apices, said three pairs of shock absorber means lying in three planes which define a first substantially equilateral triangle where they intersect the said first plate, one side of said first substantially equilateral triangle being substantially horizontal, the three vertices of said isosceles triangles formed by said three pairs of shock absorber means being connected to said second plate at three points defining a second substantially equilatral triangle one side of which is substantially horizontal, the substantially horizontal side of one of said first and second substantially equilateral triangles forming the upper side thereof, and the substantially horizontal side of said other of said first and second substantially equilateral triangles forming the lower side thereof.
Claim 3
Dependent Claim 74 words
The shock absorber arrangement of claim 1 wherein th ends of said shock absorber means forming said base apices of adjacent isosceles triangles are connected to said first plate at substantially coincident positions which also coincide with the positions of said apices of said first substantially equilateral triangle formed by the intersections of said planes in which lie said axes of said pairs of shock absorber means with the plane of said first plate.
