Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
109 words
A shock-proof watchcase comprising a case body; a case back adapted for cooperative engagement with said case body; a watch movement; a supporting ring engaged against the periphery of said watch movement for supporting said watch movement; and shockabsorbing means intermediate said supporting ring and each of said case body and case back, said supporting ring, shockabsorbing means, case back and case body being dimensioned for clearance between said supporting ring and watch movement on the one hand and said case back and case body on the other hand in both the axial and transverse directions of said watchcase so that both axial and transverse shocks may be absorbed.
Claim 2
Dependent Claim
109 words
A shock-proof watchcase comprising a case body; a case back adapted for cooperative engagement with said case body; a watch movement; a supporting ring engaged against the periphery of said watch movement for supporting said watch movement; and shockabsorbing means intermediate said supporting ring and each of said case body and case back, said supporting ring, shockabsorbing means, case back and case body being dimensioned for clearance between said supporting ring and watch movement on the one hand and said case back and case body on the other hand in both the axial and transverse directions of said watchcase so that both axial and transverse shocks may be absorbed.
Claim 3
Dependent Claim
31 words
A shock-proof watchcase as recited in claim 1, wherein said shock-absorbing means includes shock-absorbing portions projecting substantially in said axial direction for respective engagement by said case body and case back.
Claim 4
Dependent Claim
71 words
A shock-proof watchcase as recited in claim 2, wherein said supporting ring and said shock-absorbing portions of said shock-absorbing means are dimensioned so that said watch movement is spaced a greater distance from said watchcase and watch back than said supporting ring, said supporting ring being formed at least in part of a resilient material for absorbing the shock force of any engagement thereof against said case body and case back.
Claim 5
Dependent Claim
31 words
A shock-proof watchcase as recited in claim 2, wherein at least one of said shock-absorbing portions is formed as a separate element mounted intermediate said supporting ring and said case back.
Claim 6
Dependent Claim
44 words
A shock-proof watchcase as recited in claim 4, wherein at least the shock-absorbing portion engaging said case back is formed as a separate element, and is formed of a maTerial having greater resiliency than the material of the shock-absorbing portion engaging said case body.
Claim 7
Dependent Claim
42 words
A shock-proof watchcase as recited in claim 2, wherein said shock-absorbing portions are formed as an axially extending plate member engaged between said case body and case back, said shock-absorbing means including means for supporting said supporting ring on said plate member.
Claim 8
Dependent Claim
37 words
A shock-proof watchcase as recited in claim 6, wherein the respective surfaces of said case body and case back against which said plate member engages are inclined, said plate member being formed of a thin metal plate.
Claim 9
Dependent Claim
40 words
A shock-proof watchcase as recited in claim 6, wherein the respective portions of the surfaces of said case body and case back against which said plate member engages are inclined, said plate member being formed of a thin synthetic resin.
