Abstract
Abstract A housing assembly is provided for use with a remote electronic surveillance camera or the like, having a removable housing cover which permits rapid access to the interior of the housing assembly for service and adjustments. The cover is connected to the housing with a plurality of latching mechanisms which combine both latching and hinging functions in a single unit. The latching mechanisms cooperate with each other to allow hinging of the housing cover about a number of different axes, and further permit complete removal of the cover. A specially designed locking mechanism is also disclosed which provides the above-mentioned latching and hinging features while securing the housing assembly against unauthorized intrusion. The preferred embodiment of the invention further discloses a fan assembly and heating element which are used to maintain a desired temperature range inside the housing for optimum performance of an electronic surveillance camera mounted therein. The air flow pattern created by the fan assembly may also be directed past optical surfaces inside and outside of the housing to keep atmospheric contaminants such as dust and moisture from settling on the surfaces and distorting optical transmissions to the camera.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
97 words
A housing assembly for electronic surveillance apparatus, comprising: complementary first and second housing members defining an enclosed region when joined together; first hinge means for joining said first and second housing members in hinged relationship about a first axis; second hinge means for joining said first and second housing members in hinged relationship about a second axis, different from said first axis; and said first and second hinge means each having means for independently releasing its respective hinge means to permit said first and second housing members to hinge about the axis of the other hinge means.
Claim 2
Dependent Claim
97 words
A housing assembly for electronic surveillance apparatus, comprising: complementary first and second housing members defining an enclosed region when joined together; first hinge means for joining said first and second housing members in hinged relationship about a first axis; second hinge means for joining said first and second housing members in hinged relationship about a second axis, different from said first axis; and said first and second hinge means each having means for independently releasing its respective hinge means to permit said first and second housing members to hinge about the axis of the other hinge means.
Claim 3
Dependent Claim
123 words
A housing assembly as in claim 1, wherein each of said hinge means further comprises at least one latching mechanism for fastening said first and second housing members together, said latching mechanism including: shaft means mounted on said first housing member for supporting said member in hinged relation to said second member; means mounted on said second housing member for providing a hinge seat for said shaft means when said first and second housing members are joined, and shaped to receive said shaft means in a direction substantially perpendicular to said axis; and means for detachably retaining said shaft means in said hinge seat means while permitting hinged movement of said first and second housing members about the axis of said shaft means.
Claim 4
Dependent Claim
49 words
A housing assembly as in claim 2, wherein said means for detachably retaining said shaft means in said hinge seat means comprises: a latch plate mounted on said shaft means and rotatable about the axis thereof, and means for detachably securing said latch plate to said second housing member.
Claim 5
Dependent Claim
19 words
A housing assembly as in claim 1 wherein said retaining means are independently detachable from the respective shaft means.
Claim 6
Dependent Claim
65 words
A housing assembly as in claim 4, wherein said housing assembly comprises a horizontally elongated structure with vertically oriented right and left side walls, wherein said first and second housing members are joined along a substantially horizontal junction line on each of said right and left side walls, and said first and second hinge means are mounted respectively on said right and left side walls.
Claim 7
Dependent Claim
49 words
A housing assembly as in claim 2 wherein said shaft means is attached to said first housing member by a plurality of support arms extending outwardly from the surface of said first housing member and suspending said shaft means away from and substantially parallel to said first housing member.
Claim 8
Dependent Claim
45 words
A housing assembly as in claim 6 wherein said hinge seat means comprises at least one slotted member extending outwardly from the surface of said second housing member, said slot positioned to receive said shaft means when said first and second housing members are joined.
Claim 9
Dependent Claim
80 words
A housing assembly as in claim 7 wherein said retaining means comprises a clamping member having a hooked end and a free end, the tip of said hooked end dimensioned for insertion between said shaft means and said first housing member when said shaft means is seated in said slotted member, and means attached to said second housing member and to the free end of said clamping member for tensioning said free end after said insertion of said hooked end.
Claim 10
Dependent Claim
231 words
A housing assembly for electronic surveillance apparatus, comprising: complementary first and second housing members defining an enclosed region when joined together; and at least one latching mechanism for fastening said first and second housing members together, said latching mechanism including: shaft means mounted on said first housing member for supporting said member in hinged relation to said second member about the axis of said shaft means; means mounted on said second housing member for axially receiving said shaft means when said first and second housing members are joined, and means for detachably retaining said shaft means in said receiving means, including a latch plate mounted on said shaft means and rotatable about the axis thereof, and means for detachably securing said latch plate to said second housing member; said means for detachably securing said latch plate including an arm pivotally mounted on said latch plate, bracket means mounted on and extending outwardly from said second housing member forming a channel between said bracket means and said second housing member for receiving said arm, means for pivoting said arm into and out of said channel, a flange mounted on and projecting substantially perpendicularly from said second housing member, and a tab projecting from said latch plate in a substantially radial relationship to said shaft means and positioned to engage said flange when said latch plate is rotated against said second housing member.
Claim 11
Dependent Claim
231 words
A housing assembly for electronic surveillance apparatus, comprising: complementary first and second housing members defining an enclosed region when joined together; and at least one latching mechanism for fastening said first and second housing members together, said latching mechanism including: shaft means mounted on said first housing member for supporting said member in hinged relation to said second member about the axis of said shaft means; means mounted on said second housing member for axially receiving said shaft means when said first and second housing members are joined, and means for detachably retaining said shaft means in said receiving means, including a latch plate mounted on said shaft means and rotatable about the axis thereof, and means for detachably securing said latch plate to said second housing member; said means for detachably securing said latch plate including an arm pivotally mounted on said latch plate, bracket means mounted on and extending outwardly from said second housing member forming a channel between said bracket means and said second housing member for receiving said arm, means for pivoting said arm into and out of said channel, a flange mounted on and projecting substantially perpendicularly from said second housing member, and a tab projecting from said latch plate in a substantially radial relationship to said shaft means and positioned to engage said flange when said latch plate is rotated against said second housing member.
