Abstract
Abstract An environmental protection device with manually operated latching mechanism is described. The device includes a rigid hook and flexible latch on opposite peripheral edges of the device with cavity halves therebetween capable of fitting together upon the latching of the hook and latch to form an enclosure around an elongate substrate such as a coaxial cable splice or a cable to tap port connection upon the closing of the device and the locking of the latch and hook members. The device is preferably filled with a gel sealing material having an elongation of at least 100% and a Voland hardness from about 1 to 50 grams.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
146 words
An environmental protection device for an elongate substrate passing therethrough and/or there into, said device comprising: a hinged body which includes a longitudinal flexible latch member adjacent an aperture formed in said body and extending along a peripheral edge and a rigid hook member on an opposite peripheral edge of the device, first and second cavity halves therebetween capable forming a cavity to enclose around an elongate substrate upon the closing of the device and the latching of the rigid hook and flexible latch member through said aperture, at least one edge including an elongate ridge capable of being received in a trough on an opposite peripheral edge, said ridge and trough assisting in the closing of the cavity halves wherein the latch and hook have a mating force and release force which are less than the holding force of the latch and hook when mated.
Claim 2
Dependent Claim
146 words
An environmental protection device for an elongate substrate passing therethrough and/or there into, said device comprising: a hinged body which includes a longitudinal flexible latch member adjacent an aperture formed in said body and extending along a peripheral edge and a rigid hook member on an opposite peripheral edge of the device, first and second cavity halves therebetween capable forming a cavity to enclose around an elongate substrate upon the closing of the device and the latching of the rigid hook and flexible latch member through said aperture, at least one edge including an elongate ridge capable of being received in a trough on an opposite peripheral edge, said ridge and trough assisting in the closing of the cavity halves wherein the latch and hook have a mating force and release force which are less than the holding force of the latch and hook when mated.
Claim 3
Dependent Claim
21 words
The device according to claim 1 wherein the latch and hook receptacle members hinge about a living hinge between cavity halves.
Claim 4
Dependent Claim
39 words
The device according to claim 2 wherein the cavity halves are filled with a sealant material selected from the group consisting of a polyurethane gel, a silicone gel, a thermoplastic elastomer with plasticizing oil gel, or a polyurea gel.
Claim 5
Dependent Claim
24 words
The device according to claim 3 wherein the body is fabricated from a material selected from the group consisting of polypropylene, nylon, and polyetheylene.
Claim 6
Dependent Claim
30 words
The device according to claim 4 wherein the gel has a Voland hardness of from about 10 to about 50 grams and an ultimate elongation of at least about 100%.
Claim 7
Dependent Claim
31 words
The device according to claim 5 further including passages through opposite peripheral edges of the device to provide means for securing members to pass therethrough upon the closing of the device.
Claim 8
Dependent Claim
25 words
The device according to claim 6 wherein the interior of the cavity halves includes a surface treatment to enhance the adhesion of the gel thereto.
Claim 9
Dependent Claim
29 words
The device according to claim 7 wherein the surface treatment is selected from the group consisting of chemical etching, glow discharge etching, and a plurality of ribs molded therein.
Claim 10
Dependent Claim
76 words
The environmental protection device according to claim 5 further including a second hingeable body having first and second cavity halves and a hook and latch mechanism on peripheral edges wherein the hook of the second body mates to the latch of the first body and the latch of the first body mates with the hook of the second body to seals parallel coaxial cable splices passing containing coaxial cable passing therethrough within the mated cavity halves.
Claim 11
Dependent Claim
28 words
The device according to claim 5 further including two coaxial cable connectors spliced together across a coaxial cable splice and sealed within the cavity of the cavity halves.
Claim 12
Dependent Claim
14 words
The device according to claim 4 wherein the latch flexes about a living hinge.
Claim 13
Dependent Claim
98 words
In an environmental protection device for coaxial cable, coaxial cable connectors, splices and/or tap or splitter signal ports, the improvement which comprises: a rigid hook and a flexible latch along opposite edges of the coaxial cable, coaxial cable connector, tap port or signal port protection device, said hook and latch exhibit a holding together force upon connecting together which is greater than the force required to unlatch the hook and latch, said latch adjacent an aperture formed in said device and flexes towards a body of the device for unlatching from the hook which extend through said aperture.
Claim 14
Dependent Claim
98 words
In an environmental protection device for coaxial cable, coaxial cable connectors, splices and/or tap or splitter signal ports, the improvement which comprises: a rigid hook and a flexible latch along opposite edges of the coaxial cable, coaxial cable connector, tap port or signal port protection device, said hook and latch exhibit a holding together force upon connecting together which is greater than the force required to unlatch the hook and latch, said latch adjacent an aperture formed in said device and flexes towards a body of the device for unlatching from the hook which extend through said aperture.
Claim 15
Dependent Claim
30 words
The device according to claim 11 wherein the gel has a Voland hardness of from about 10 to about 50 grams and an ultimate elongation of at least about 100%.
Claim 16
Dependent Claim
14 words
The device according to claim 13 wherein the latch flexes about a living hinge.
Claim 17
Dependent Claim
39 words
The device according to claim 14 wherein the cavity halves are filled with a sealant material selected from the group consisting of a polyurethane gel, a silicone gel, a thermoplastic elastomer with plasticizing oil gel, or a polyurea gel.
Claim 18
Dependent Claim
45 words
The device according to claim 1 wherein the periphery of the trough adjacent the rigid hook restricts the outward movement of the rigid hook member so as to retain the device closed in the absence of the flexing of the latch member towards the body.
