Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
82 words
A waterproof seal for a push-button in a panel; comprising a shroud of flexible and resilient material having a substantially cylindrical portion and an end wall closing one end to shroud the push-button; said end wall being normally resiliently biased from a first to a second position in which said end wall is inwardly collapsed to provide a visual and tactile indication of the position of the push-button; and sealing means for sealing the open end of said shroud to the panel.
Claim 2
Dependent Claim
82 words
A waterproof seal for a push-button in a panel; comprising a shroud of flexible and resilient material having a substantially cylindrical portion and an end wall closing one end to shroud the push-button; said end wall being normally resiliently biased from a first to a second position in which said end wall is inwardly collapsed to provide a visual and tactile indication of the position of the push-button; and sealing means for sealing the open end of said shroud to the panel.
Claim 3
Dependent Claim
26 words
A waterproof seal as in claim 1, in which said end wall is provided with at least one coaxially positioned circular groove to produce said bias.
Claim 4
Dependent Claim
44 words
A waterproof seal in accordance with claim 1, in which said sealing means comprises an internally screw-threaded substantially cylindrical insert sealingly adjoining said substantially cylindrical portion and coaxially aligned therewith; said insert being adapted to cooperate with an externally screw-threaded member surrounding the button.
Claim 5
Dependent Claim
127 words
A sealed push-button assembly, comprising a push-button mounted in a panel for movement between extended and retracted positions, an upstanding cylindrical member mounted on the panel and surrounding the push-button, and a waterproof seal surrounding the upstanding cylindrical member and shrouding the push-button, said seal comprising a shroud of flexible and resilient material having a substantially cylindrical portion and an end wall closing one end, said end wall being normally resiliently biased from a first to a second position in which said end wall is inwardly collapsed to provide a visual and tactile indication of the position of the push-button, said waterproof seal having engaging means cooperating with the unstanding cylindrical member to effect sealing by compression of the open end of said seal against the panel.
Claim 6
Dependent Claim
127 words
A sealed push-button assembly, comprising a push-button mounted in a panel for movement between extended and retracted positions, an upstanding cylindrical member mounted on the panel and surrounding the push-button, and a waterproof seal surrounding the upstanding cylindrical member and shrouding the push-button, said seal comprising a shroud of flexible and resilient material having a substantially cylindrical portion and an end wall closing one end, said end wall being normally resiliently biased from a first to a second position in which said end wall is inwardly collapsed to provide a visual and tactile indication of the position of the push-button, said waterproof seal having engaging means cooperating with the unstanding cylindrical member to effect sealing by compression of the open end of said seal against the panel.
Claim 7
Dependent Claim
63 words
An assembly in accordance with claim 4, in which said engaging means comprises an internally screw-threaded substantially cylindrical insert in said substantial cylindrical portion of said seal sealingly adjoining the same and coaxially aligned therewith, and a screw-threaded outer surface on said upstanding cylindrical member threadedly engagable with said insert to effect compression of the open end of said seal against said panel.
