Abstract
Abstract A waterproof housing for electrical or electronic test equipment with an opening at the rear for equipment and having a flap at the front, the flap hinged upwardly to open and close an aperture for operating or viewing instruments of the equipment. Ideally, two identical housings may be joined rear-to-rear to form an assembly with a partition between them to close the openings and seal equipment inside one of the housings. Movement of the flap is desirably frictionally resisted to allow it to be located in any desired position. With the flap closed, a gap is formed between flap and housing for passage of wiring from the equipment. Preferably, the housing has inner and outer skin layers which are relatively resiliently movable and a compressible foam may be between skin layers.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
96 words
A housing for electrical or electronic test equipment made from waterproof material, having inner and outer skin layers which are relatively resiliently movable upon application of pressure, defining a chamber for containing electrical or electronic test set equipment and comprising a closed top, two sidewalls and a base, a rear defining an opening to admit the equipment into the chamber, and a front wall defining an aperture to the chamber, and a flap on said housing for closing the aperture, the flap being hinged at an upper edge for upward hinging movement away from the aperture.
Claim 2
Dependent Claim
96 words
A housing for electrical or electronic test equipment made from waterproof material, having inner and outer skin layers which are relatively resiliently movable upon application of pressure, defining a chamber for containing electrical or electronic test set equipment and comprising a closed top, two sidewalls and a base, a rear defining an opening to admit the equipment into the chamber, and a front wall defining an aperture to the chamber, and a flap on said housing for closing the aperture, the flap being hinged at an upper edge for upward hinging movement away from the aperture.
Claim 3
Dependent Claim
15 words
A housing according to claim 1 comprising means closing the opening in the rear wall.
Claim 4
Dependent Claim
28 words
A housing according to claim 1 wherein the hinge offers frictional resistance to movement of the flap to enable the flap to be located in any pivotal position.
Claim 5
Dependent Claim
42 words
A housing according to claim 1 wherein when the flap is in a position closing the aperture, the front wall and the flap define between them at least one gap to enable electrical or transmission wiring to pass through from the chamber.
Claim 6
Dependent Claim
47 words
A housing assembly comprising a first housing according to claim 1 and a second housing, the second housing being attached to the first housing so as to close the rear opening, the second housing defining a chamber which is separated from the chamber of the first housing.
Claim 7
Dependent Claim
41 words
An assembly according to claim 5 wherein the second housing has an opening to its chamber and is attached to the first housing with the two openings opposing one another, and a partition is provided which is located between the housings.
Claim 8
Dependent Claim
43 words
An assembly according to claim 6 including electrical test equipment in the chamber of the first housing, the equipment being detachably mounted within the first housing and having electrical instruments located in line with the aperture for viewing with the flap pivoted upwards.
Claim 9
Dependent Claim
27 words
An assembly according to claim 7 wherein the equipment is mounted within a shock absorbing moisture resistant surround which is detachable with the equipment from the chamber.
Claim 10
Dependent Claim
54 words
An assembly according to claim 8 wherein the surround has a top wall, bottom wall and front and side walls contacting respective walls of the first housing, the surround also defining a rear opening for insertion and removal of the equipment and the partition is sealed to the surround around the surround rear opening.
Claim 11
Dependent Claim
16 words
A combination according to claim 1 wherein a compressible foam is located between the skin layers.
Claim 12
Dependent Claim
15 words
A combination according to claim 5 wherein the housings are of identical size and shape.
Claim 13
Dependent Claim
170 words
A housing and electrical or electronic test equipment assembly comprising a housing made from waterproof material comprising a closed top, two sidewalls and a base defining a chamber, a rear defining an opening to admit the equipment into the chamber, and a front wall defining an aperture to the chamber, a flap on said housing for closing the aperture, the flap being hinged at an upper edge for upward hinging movement away from the aperture, electrical or electronic test set equipment in the chamber of the housing, the equipment having electrical instruments located in line with the aperture for viewing with the flap pivoted upwards, a shock absorbing moisture resistant surround containing the equipment and being detachable with the equipment from the chamber, the surround having a top wall, bottom wall and front and side walls contacting respective walls of the housing, the surround also defining a rear opening for insertion and removal of the equipment, and a partition which is sealed to the surround around the surround rear opening.
