Abstract

Abstract Shock absorbing device having an outer and an inner section supported for relative movement with respect to each other in the direction of a shock force, an intermediate section placed into the space formed by the outer and inner sections and comprising a material having volume-elastic properties, the elastic material is treated with a material having adhesive properties for delaying the return of it into the original position due to its elastic properties after a shock force causing compression of the elastic material has ceased, and wherein the outer section comprises an elastic material a portion of which is formed to receive the volume-elastic intermediate section, and the inner section lying closer to the object to be protected from the shock is made from a rigid profile and supports the outer section containing the volume-elastic material.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 161 words
Shock absorbing device comprising a first shaped section and a second shaped section supported for relative movement with respect to each other in the direction of a shock force; an intermediate section placed into the space formed by said first and second sections and comprising a material having volume-elastic properties, said properties being such that the return into the rest position by said intermediate section material after a shock force caused compression of said intermediate section material is delayed; said first section comprising an elastic material and forming part of an enclosure structure for said volume-elastic intermediate section, said second section being made from a rigid material and supporting said enclosure structure containing said volumeelastic material; said second section being channel shaped and the open side of which facing the intermediate section and forming a receiving space operable for receiving at least portions of said volumeelastic material in compressed form when said first section has been displaced by the shock force.
Claim 2
Dependent Claim 161 words
Shock absorbing device comprising a first shaped section and a second shaped section supported for relative movement with respect to each other in the direction of a shock force; an intermediate section placed into the space formed by said first and second sections and comprising a material having volume-elastic properties, said properties being such that the return into the rest position by said intermediate section material after a shock force caused compression of said intermediate section material is delayed; said first section comprising an elastic material and forming part of an enclosure structure for said volume-elastic intermediate section, said second section being made from a rigid material and supporting said enclosure structure containing said volumeelastic material; said second section being channel shaped and the open side of which facing the intermediate section and forming a receiving space operable for receiving at least portions of said volumeelastic material in compressed form when said first section has been displaced by the shock force.
Claim 3
Dependent Claim 45 words
Shock absorbing device as claimed in claim 1, wherein said enclosure structure has a cross-section of a U the basis of which forming said first section and having edge portions including shaped sections forming positive locking with counter shaped sec-tions formed on the second section.
Claim 4
Dependent Claim 43 words
Shock absorbing device as claimed in claim 2, wherein said enclosure includes elastic lip portions abutting against said second section, said lIp potions having a rigidity greater in the direction of the shock than the rigidity of the adjoining parts of said enclosure.
Claim 5
Dependent Claim 31 words
Shock absorbing device as claimed in claim 1, wherein said second section has associated therewith at least a pair of spring fingers secured to said first section at their end portions.
Claim 6
Dependent Claim 31 words
Shock absorbing device as claimed in claim 1, wherein said enclosure includes a resilient metal strip, said metal strip supporting said first section about the end portion of said intermediate section.
Claim 7
Dependent Claim 26 words
Shock absorbing device as claimed in claim 2, said edge portions of said first sections including also portions for covering the regions of said positive locking.
Claim 8
Dependent Claim 44 words
Shock absorbing device as claimed in claim 1, wherein said second section has an inner portion including hook portions, said enclosure having projections engaging the hook portions of said inner portion and thereby forming a positive locking between said first and said second sections.
Claim 9
Dependent Claim 42 words
Shock absorbing device according to claim 6, said first section and said metal strip defining a passage, a recess in said volume-elastic material opposite said passage, a lamp disposed in said recess, and means for supporting said lamp on said metal strip.
Claim 10
Dependent Claim 35 words
Shock absorbing device as claimed in claim 8, wherein said second section is formed to accommodate said lamp moving into it during a shock absorbing action to prevent destruction of said lamp by said shock.
Claim 11
Dependent Claim 23 words
Shock absorbing device according to claim 1, said receiving space having a reduced volume with respect to the volume of said volume-elastic material.
