Abstract
Abstract A shock absorbing pad is formed of first and second interleaved constituent components of different hardness which are interleaved through the thickness of the pad for absorbing forces applied in the direction of the pad thickness. The pads are formed by die cutting interim pads from mats of the first and second materials with the pads comprising constituent components that are separable. The constituent components are separated and respectively associated with different constituent components formed of the other material to provide the desired pad formed of the two interleaved different materials.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
95 words
A method of forming composite shock absorbing padding of first and second materials having different hardness, said method comprising the steps of die cutting mats of said first and second materials by the use of identical dies or a single die to provide (interim) transient pads formed of a single material and comprising first and second mating constituent components; disassembling the interim pad components; and associating each constituent component formed from the first material with a mating constituent component of the second material to provide a composite pad formed of interleaved harder and softer materials.
Claim 2
Independent Claim
95 words
A method of forming composite shock absorbing padding of first and second materials having different hardness, said method comprising the steps of die cutting mats of said first and second materials by the use of identical dies or a single die to provide (interim) transient pads formed of a single material and comprising first and second mating constituent components; disassembling the interim pad components; and associating each constituent component formed from the first material with a mating constituent component of the second material to provide a composite pad formed of interleaved harder and softer materials.
Claim 3
Dependent Claim
27 words
The method of claim 1 wherein said constituent components each include a plurality of parallel finger elements extending from a common base element of each constituent component.
Claim 4
Dependent Claim
17 words
The method of claim 2 wherein said constituent components each comprise a series of interconnected L-shaped elements.
Claim 5
Dependent Claim
24 words
The method of claim 1 wherein one of said constituent components comprises a series of connected H-shaped elements received within the other constituent component.
Claim 6
Dependent Claim
21 words
The method of claim 1 wherein said constituent components each comprise a series of linear fingers connected to form square spirals.
Claim 7
Dependent Claim
55 words
A shock absorbing pad formed of first and second constituent components respectively comprising materials of different hardness and each including a plurality of parallel elements extending from a common base element of each constituent component wherein said elements of each of the different constituent components are interleaved with the elements of the other constituent component.
Claim 8
Dependent Claim
55 words
A shock absorbing pad formed of first and second constituent components respectively comprising materials of different hardness and each including a plurality of parallel elements extending from a common base element of each constituent component wherein said elements of each of the different constituent components are interleaved with the elements of the other constituent component.
Claim 9
Dependent Claim
28 words
A shock absorbing pad as recited in claim 6 wherein one of said constituent components comprises a series of connected H-shaped elements positioned within the other constituent component.
Claim 10
Dependent Claim
26 words
A shock absorbing pad as recited in claim 6 wherein said constituent components each comprise a series of linear fingers connected to form a square spiral.
Claim 11
Dependent Claim
21 words
A shock absorbing pad as recited in claim 6 wherein said constituent components each comprise a series of interconnected L-shaped elements.
Claim 12
Dependent Claim
62 words
A relatively flat shock absorbing pad having thickness, length, and breadth dimensions with the thickness dimension being substantially less than the other dimensions comprising first and second interleaved constituent components formed of materials of different hardness with both constituent components extending through the entire thickness of said pad for absorbing forces applied to the pad in the direction of the pad thickness.
Claim 13
Dependent Claim
62 words
A relatively flat shock absorbing pad having thickness, length, and breadth dimensions with the thickness dimension being substantially less than the other dimensions comprising first and second interleaved constituent components formed of materials of different hardness with both constituent components extending through the entire thickness of said pad for absorbing forces applied to the pad in the direction of the pad thickness.
Claim 14
Dependent Claim
185 words
A shock absorbing pad as recited in claim 10 wherein one of said constituent elements comprises an enclosing member in which the other constituent element is enclosedly positioned, said enclosing member including semicircular end portions joined by linear side elements, linear arm members extending inwardly from central portions of said linear side elements, parallel internal linear elements extending perpendicularly from the inner extent of said linear arm members, inwardly curved connector portions extending inwardly from opposite ends of said parallel internal linear elements and parallel innermost linear elements 90 extending toward the center of the pad from one end of each of said inwardly curved connector portions, said other constituent element comprising two U-shaped inwardly facing portions each respectively positioned between one semicircular end portion, a portion of a linear side element, the linear arm members, a portion of the parallel internal linear elements and two of the inwardly curved connector portions, said other constituent element further including a longitudinal central portion extending between the inwardly facing U-shaped portions and first and second T-shaped portions extending transversely from opposite sides of the longitudinal central portion.
Claim 15
Dependent Claim
28 words
A shock absorbing pad as recited in claim 10 wherein one of said constituent components comprises a series of connected H-shaped elements positioned within the other constituent component.
Claim 16
Dependent Claim
26 words
