Abstract
Abstract The protective anti-shock jacket for instruments for personal and professional use, in particular for portable remote control units, is of the structurally monolithic type made in elastomer material, and exhibits in its inferior wall one or more windows or slits destined to reduce tension on the other walls, which tension is relative to the elastic reaction of the material of the elastically deformed jacket, with the insertion of the instrument into the jacket.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
111 words
A shock-proof protective jacket housing a portable remote-control unit of the single-body type, said jacket being made from an elastomer material and having six walls, one of which is a top wall with a large window for insertion of a remote control unit therethrough and for external access to said unit, a bottom wall, two end walls and two lateral side walls defining the jacket, wherein the bottom wall comprises one or more slits in proximity to at least one other wall, wherein each slit reduces the tension on the other walls resulting from an elastic reaction of the jacket material deformed by the insertion of the unit into the jacket.
Claim 2
Dependent Claim
111 words
A shock-proof protective jacket housing a portable remote-control unit of the single-body type, said jacket being made from an elastomer material and having six walls, one of which is a top wall with a large window for insertion of a remote control unit therethrough and for external access to said unit, a bottom wall, two end walls and two lateral side walls defining the jacket, wherein the bottom wall comprises one or more slits in proximity to at least one other wall, wherein each slit reduces the tension on the other walls resulting from an elastic reaction of the jacket material deformed by the insertion of the unit into the jacket.
Claim 3
Dependent Claim
70 words
A protective jacket as in claim 1, characterized by the fact that in one or more portions of said lateral side walls, or in a whole intermediate part of said lateral side walls comprised between the two ends of the jacket, and in one or two contiguous portions of the top wall and the bottom wall, there are areas of greater thickness connected and alternated with areas of lesser thickness.
Claim 4
Dependent Claim
64 words
A jacket as in claim 1, characterized by the fact that in one or more portions of the lateral side walls or in a whole intermediate part of said side walls comprised between the two ends of the jacket, and in one or more contiguous portions of the top wall and the bottom wall, there is a longitudinal section conformed in a bellows shape.
Claim 5
Dependent Claim
40 words
A jacket as in claim 1, wherein the edge of the window and the edge of each slit exhibits a swelling or reinforcement along at least its longer sides, and characterized by the fact that said edges are not sharp.
Claim 6
Dependent Claim
36 words
A jacket as in claim 4, wherein said window edge exhibits in section a back draft going from the outside towards the inside, and wherein said edge is relatively thinner at its outside than its inside.
Claim 7
Dependent Claim
36 words
A jacket as in claim 1, wherein each slit is closed by a thin film of the same material as the jacket itself, which film is obtained during a production by forming of the said jacket.
Claim 8
Dependent Claim
26 words
A jacket as in claim 1, wherein said side walls include stretchable areas of lesser thickness than a thickness of the end walls of the jacket.
Claim 9
Dependent Claim
48 words
A jacket as in claim 1, wherein said bottom wall has an intermediate part that is of lesser thickness than a perimetral frame of said bottom wall, which frame is connected with the side walls of the jacket and that each slit is made in said intermediate part.
Claim 10
Dependent Claim
42 words
A jacket as in claim 1, characterized by the fact of having in at least one of its two end walls an opening for the transmission to the outside of a signal emitted by a remote control unit housed in said jacket.
Claim 11
Dependent Claim
58 words
A jacket as in claim 9, wherein a flat element is provided at each said opening, which flat element is resistant to bending and transparent to the signal emitted by said unit, said flat element stably interpositionable between the adjacent end of said unit and substantially the peripheral part of an internal surface of the adjacent end wall.
Claim 12
Dependent Claim
43 words
A jacket as in claim 10, characterized by the fact that it exhibits a peripheral groove sunk into an internal surface of each end wall exhibiting a said opening and destined to hold in place the correspondence flat element at a perimetrical edge.
Claim 13
Dependent Claim
62 words
A jacket as in claim 10, characterized by the fact that, for the stable positioning of each flat element, ridges are provided inside the jacket and are arranged facing the internal surface of each end wall exhibiting a said opening, said ridges having a substantially tooth-shaped cross-section appearance and having a face which is closest to the end wall parallel to it.
Claim 14
Dependent Claim
52 words
A jacket as in claim 1, characterized by the fact that it exhibits on an internal surface of its sides at least one flap projecting towards the inside of said jacket for a short distance, said at least one flap preferably being inclined with respect to the longitudinal centre-line of the jacket.
Claim 15
Dependent Claim
13 words
A jacket as in claim 1, wherein each slit exhibits a geometrical shape.
Claim 16
Dependent Claim
25 words
A jacket as in claim 1, wherein said one or more slits are comprised of a number of openings aligned in one or more lines.
Claim 17
Dependent Claim
103 words
A jacket as in claim 1, characterized by the fact that said elastomer material comprises a microcellular polyurethane pressed with 0.4 g/cm 3 pressing density; the choice of the components, taken from the isocyanates and the polyhydric alcohol families, in order to obtain the following mechanical characteristics for the body of the jacket: hardness of the pressed object, Shore A from 3 to 70; maximum tensile stress from 6 to 50 kg/cm 2 ; stretching from 200 to 250%; tearing resistance from 1.2 to 6 kg/cm; abrasion (DIN 53516) from 350 to 150 g.; compressive strength from 0.4 to 7.5 kg/cm 2 .
Claim 18
Dependent Claim
61 words
A remote control instrument shock-proof protective jacket comprising a casing having a top wall, a bottom wall, two side walls and two end walls, said casing comprised substantially of an elastomer material, said top wall including at least one large window, said bottom wall including at least one slit in proximity to at least one side wall or one end wall.
Claim 19
Dependent Claim
61 words
A remote control instrument shock-proof protective jacket comprising a casing having a top wall, a bottom wall, two side walls and two end walls, said casing comprised substantially of an elastomer material, said top wall including at least one large window, said bottom wall including at least one slit in proximity to at least one side wall or one end wall.
