Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
143 words
A shock mount for mounting an electrical apparatus to a chassis comprising: a resilient buffer mounted to said apparatus for compressive shock absorption along a first line; and an L-shaped arm having a first arm portion and a second arm portion, said first arm portion extending along a second line normal to said first line, said first arm portion having support means supporting said resilient buffer at one end thereof, said second arm portion extending along a third line normal to said first and second lines, one end of said second arm portion being joined to the end of said first arm portion opposite the end supporting said resilient buffer and the other end of said second arm portion joined to and integral with said chassis, said L-shaped, are being so sized as to support bending and torsional loads to absorb mechanical shock.
Claim 2
Dependent Claim
143 words
A shock mount for mounting an electrical apparatus to a chassis comprising: a resilient buffer mounted to said apparatus for compressive shock absorption along a first line; and an L-shaped arm having a first arm portion and a second arm portion, said first arm portion extending along a second line normal to said first line, said first arm portion having support means supporting said resilient buffer at one end thereof, said second arm portion extending along a third line normal to said first and second lines, one end of said second arm portion being joined to the end of said first arm portion opposite the end supporting said resilient buffer and the other end of said second arm portion joined to and integral with said chassis, said L-shaped, are being so sized as to support bending and torsional loads to absorb mechanical shock.
Claim 3
Dependent Claim
44 words
Apparatus according to claim 1 wherein said support means comprises a tab portion formed at said one end of said first arm portion, said tab defining a plane normal to said first line, said buffer being sandwiched between said tab portion and said apparatus.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 2 wherein said tab includes an aperture and said buffer is at least partially supported in said aperture.
Claim 5
Dependent Claim
28 words
Apparatus according to claim 1 wherein said support means comprises an extension of said arm compressively wrapped about at least a portion of the periphery of said buffer.
