Abstract
Abstract A compression coupling system is employed for attaching one optical or electro-optical component to another in a manner such that different diameters of devices readily may be coupled together without causing any cosmetic defects from the coupling function. The first component to which the other component is to be attached has a cylindrical portion on it; and the other component has a hollow cylindrical extension on it, with an internal diameter which is equal to or greater than the external diameter of the first component. A cylindrical sleeve/shim having a thickness which is equal to the difference between the external diameter of the first component and the internal diameter of the extension is placed between the two devices which then are fitted, one over the other. A compression ring and locking ring secure the devices together by compressing the locking ring onto the body of the first component.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
220 words
A device for coupling a second optical component to a first optical component, wherein said first optical component is mounted in a first housing having a cylindrical portion of a predetermined external diameter extending therefrom, said device including in combination: a second housing for said second optical component, said second housing having a hollow cylindrical extension thereon, the internal diameter of which is at least equal to said predetermined external diameter of said cylindrical portion of said first housing, said hollow cylindrical extension of said second housing being placed over and surrounding said cylindrical portion of said first housing; a hollow cylindrical sleeve/shim having a thickness which is equal to the difference between the external diameter of said cylindrical portion of said first housing and the internal diameter of said hollow cylindrical extension of said second housing, said sleeve/shim being located between said cylindrical portion of said first housing and said hollow extension of said second housing, with said hollow extension of said second housing being placed over said cylindrical portion of said first housing, whereby said cylindrical portion of said first housing and said hollow extension of said second housing become axially aligned with each other; and means for resiliently and releasably securing said cylindrical portion of said first housing and said hollow extension of said second housing together.
Claim 2
Independent Claim
220 words
A device for coupling a second optical component to a first optical component, wherein said first optical component is mounted in a first housing having a cylindrical portion of a predetermined external diameter extending therefrom, said device including in combination: a second housing for said second optical component, said second housing having a hollow cylindrical extension thereon, the internal diameter of which is at least equal to said predetermined external diameter of said cylindrical portion of said first housing, said hollow cylindrical extension of said second housing being placed over and surrounding said cylindrical portion of said first housing; a hollow cylindrical sleeve/shim having a thickness which is equal to the difference between the external diameter of said cylindrical portion of said first housing and the internal diameter of said hollow cylindrical extension of said second housing, said sleeve/shim being located between said cylindrical portion of said first housing and said hollow extension of said second housing, with said hollow extension of said second housing being placed over said cylindrical portion of said first housing, whereby said cylindrical portion of said first housing and said hollow extension of said second housing become axially aligned with each other; and means for resiliently and releasably securing said cylindrical portion of said first housing and said hollow extension of said second housing together.
Claim 3
Dependent Claim
38 words
The combination according to claim 1, wherein said securing means comprises a resilient compression ring held in compression contact with said extension on said second housing and the exterior surface of said cylindrical portion of said first housing.
Claim 4
Dependent Claim
117 words
The combination according to claim 1, wherein said securing means comprises a compression ring means having an internal diameter substantially equal to the external diameter of said cylindrical portion of said first housing; wherein said hollow cylindrical extension of said second housing has an open end and a substantially closed end, and said compression ring means abuts the open end of said hollow extension of said second housing; and further including a locking ring means extending over and engaging said compression ring means and coupled with said hollow extension of said second housing for compressing said compression ring means and simultaneously forcing said compression ring means into tight engagement with said cylindrical portion of said first housing.
Claim 5
Dependent Claim
74 words
The combination according to claim 3, wherein said compression ring means has opposing outer edges thereof beveled at a predetermined angle, and wherein the end of said hollow cylindrical extension of said second housing has a first corresponding mating bevel and said locking ring has a second corresponding mating bevel for engaging opposite sides of said compression ring means when said locking ring means is secured to said hollow extension of said second housing.
Claim 6
Dependent Claim
65 words
The combination according to claim 4, wherein said locking ring means and said hollow cylindrical extension of said second housing have mating releaseable securing means thereon for tightly engaging said compression ring means in one position thereof and for releasing said compression ring means in a second position thereof, for correspondingly attaching and releasing said second housing from said cylindrical portion of said first housing.
Claim 7
Dependent Claim
37 words
The combination according to claim 5, wherein said mating releasable securing means comprises an external threaded portion on said hollow cylindrical extension of said second housing and a mating internal threaded portion on said locking ring means.
Claim 8
Dependent Claim
51 words
The combination according to claim 6, wherein the axis of the cylindrical portion of said first housing comprises the optical axis of component mounted in said first housing, and the axis of said hollow cylindrical extension of said second housing comprises the optical axis of component mounted in said second housing.
Claim 9
Dependent Claim
51 words
The combination according to claim 1, wherein the axis of the cylindrical portion of said first housing comprises the optical axis of component mounted in said first housing, and the axis of said hollow cylindrical extension of said second housing comprises the optical axis of component mounted in said second housing.
