Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
172 words
A fail safe resilient mount having: (a) an outer dome shaped member with an opening centered about an apex thereof and oppositely disposed ears extending therefrom with an inner bell shaped member with a top smaller than its bottom, protruding partially through said opening but restricted from complete passage through said opening by degree of taper between said top and bottom relative to size of the opening; (b) said inner bell shaped member offset partially axially within said outer member and having a centered aperture at top thereof with an aligned locking member therein (c) a block of elastomeric material having a hollow through the center to permit a fastener to be attached to the locking member, said block bonding said outer dome shaped member and inner bell shaped member in their relationship by extending between said members and covering other exposed surfaces of said inner bell shaped members and said outer dome shaped members and extending above top of said projection of said inner member to distribute shock between said members.
Claim 2
Dependent Claim
172 words
A fail safe resilient mount having: (a) an outer dome shaped member with an opening centered about an apex thereof and oppositely disposed ears extending therefrom with an inner bell shaped member with a top smaller than its bottom, protruding partially through said opening but restricted from complete passage through said opening by degree of taper between said top and bottom relative to size of the opening; (b) said inner bell shaped member offset partially axially within said outer member and having a centered aperture at top thereof with an aligned locking member therein (c) a block of elastomeric material having a hollow through the center to permit a fastener to be attached to the locking member, said block bonding said outer dome shaped member and inner bell shaped member in their relationship by extending between said members and covering other exposed surfaces of said inner bell shaped members and said outer dome shaped members and extending above top of said projection of said inner member to distribute shock between said members.
Claim 3
Dependent Claim
38 words
A mount according to claim 1 wherein said mount has a size from about 4 inches from ear and about 11/2 inches in height, to about 2 inches from ear to ear and about 3/4 inches in height.
Claim 4
Dependent Claim
18 words
A mount according to claim 1, wherein said ears have an aperture therein to receive a fastening member.
Claim 5
Dependent Claim
28 words
A mount according to claim 1, wherein said aperture in said inner member has a sufficient diameter to allow a load fastening member to engage said locking member.
Claim 6
Dependent Claim
43 words
A mount according to claim 1, wherein said inner member has a polygonal shaped inner surface sidewall extending from the top of a inner surface to about a mid portion of said inner member to receive and hold said locking member against turning.
Claim 7
Dependent Claim
56 words
A mount according to claim 5, wherein said sidewall is slightly smaller in diameter than said locking member so that insertion of said locking member into said inner member will require the exertion of sufficient force to provide a frictional lock between the outer surface of said locking member and said sidewall of said inner member.
Claim 8
Dependent Claim
31 words
A mount according to claim 6, wherein said elastomeric material is further interposed between and bonded to a inner surface of said sidewall and said outer surface of said locking member.
Claim 9
Dependent Claim
20 words
A mount according to claim 1, wherein said dome shaped member and the inner bell shaped member are frustoconically shaped.
Claim 10
Dependent Claim
31 words
A mount according to claim 1, wherein said locking member is a threaded portion of an inner surface of said inner bell shaped member to engage a threaded load anchoring member.
Claim 11
Dependent Claim
16 words
A mount according to claim 1, wherein said inner and outer members are a reinforced composite.
Claim 12
Dependent Claim
17 words
A mount according to claim 1, wherein said inner and outer members are a reinforced graphite composite.
