Abstract
Abstract A combined shutter and awning protective device for an opening in a wall such as a window, comprising a plurality of slats of uniform cross-section slidably received within one another and having a rotary member by means of which the shutter can be rolled upon the rotary member to provide for raising and lowering thereof. The device includes frame members which are pivotable whereby the device can be pivoted outwardly from a wall or the like to act as an awning. The device also includes frame sections secured to the wall which allows the device, in its non-pivoted position with the shutter fully lowered, to secure itself in position over the window or the like to act as a protective and security covering.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
272 words
A protective shutter device for an opening in a wall or the like comprising an articulated curtain made of a plurality of identical interlocked elongated rigid slats each assembled hingedly relative to an adjoining slat and each having a rod-like integral projection extending along an edge thereof and a socket-like integral portion extending along the other edge thereof whereby said plurality of slats are assembled together by sliding the rod-like projection along an edge of a slat through the socket-like edge portion of another slat, a pair of guide frame members each mounted on one side of said articulated curtain and having a groove slidably receiving an end of each of said slats, and a drive mechanism for raising and lowering said articulated curtain, said drive mechanism comprising a shaft having an axis of rotation disposed substantially parallel to the longitudinal axis of said slats, means rotatably supporting said shaft at the top of said opening, at least a pair of lugs mounted on said shaft and extending radially from said shaft, means attaching one of said slats disposed at an end of said articulated curtain to one of said lugs whereby rotation of said shaft in one direction causes said articulated curtain to be raised and said slats to be wound around said shaft in spaced apart relationship from said shaft, gear drive means driving said shaft in said one direction for raising said articulated curtain and in an opposite direction for lowering said articulated curtain, and gear drive locking means for controllably locking said gear drive means against rotation when not in operation for raising and lowering said articulated curtain.
Claim 2
Dependent Claim
272 words
A protective shutter device for an opening in a wall or the like comprising an articulated curtain made of a plurality of identical interlocked elongated rigid slats each assembled hingedly relative to an adjoining slat and each having a rod-like integral projection extending along an edge thereof and a socket-like integral portion extending along the other edge thereof whereby said plurality of slats are assembled together by sliding the rod-like projection along an edge of a slat through the socket-like edge portion of another slat, a pair of guide frame members each mounted on one side of said articulated curtain and having a groove slidably receiving an end of each of said slats, and a drive mechanism for raising and lowering said articulated curtain, said drive mechanism comprising a shaft having an axis of rotation disposed substantially parallel to the longitudinal axis of said slats, means rotatably supporting said shaft at the top of said opening, at least a pair of lugs mounted on said shaft and extending radially from said shaft, means attaching one of said slats disposed at an end of said articulated curtain to one of said lugs whereby rotation of said shaft in one direction causes said articulated curtain to be raised and said slats to be wound around said shaft in spaced apart relationship from said shaft, gear drive means driving said shaft in said one direction for raising said articulated curtain and in an opposite direction for lowering said articulated curtain, and gear drive locking means for controllably locking said gear drive means against rotation when not in operation for raising and lowering said articulated curtain.
Claim 3
Dependent Claim
87 words
The protective shutter of claim 1 wherein said gear drive locking means comprises a gear box, a drive shaft journalled in said gear box, a first bevel gear mounted on said drive shaft, a second bevel gear meshing with said first bevel gear, means coupling said second bevel gear to said first mentioned shaft, mating locking teeth on said drive shaft and in said gear box for holding said drive shaft against rotation, and means for disengaging said mating teeth for permitting rotation of said drive shaft.
Claim 4
Dependent Claim
22 words
The protective shutter device of claim 2 wherein an end of said drive shaft has means for coupling with a driving handle.
Claim 5
Dependent Claim
71 words
The protective shutter device of claim 2 wherein said means coupling said second bevel gear to said first mentioned shaft comprises an intermediary shaft having said second bevel gear mounted on one end thereof, a third bevel gear mounted on the other end of said intermediary shaft and a fourth bevel gear mounted on an end of said first mentioned shaft, said fourth bevel gear meshing with said third bevel gear.
Claim 6
Dependent Claim
59 words
The protective shutter device of claim 4 wherein said third and fourth bevel gears are disposed in a second gear box, each of said third and fourth bevel gears is mounted on a stub shaft journaled in said gear box, and said intermediary shaft is coupled to one of said stub shafts by means of a spline coupling arrangement.
Claim 7
Dependent Claim
61 words
The protective shutter device of claim 1 further comprising a bar member hingedly attached to the slat disposed at the other end of said articulated curtain, a T-shaped end portion at each lateral end of said bar member, and a T-shaped groove in each of said side frame members for slidably receiving one said T-shaped end portion of said bar member.
Claim 8
Dependent Claim
42 words
The protective shutter device of claim 6 further comprising locking means in said bar member having a reciprocable tongue member engageable in a corresponding recess in each of said side frame members for locking said articulated curtain in an extreme lowered position.
Claim 9
Dependent Claim
105 words
The protective shutter device of claim 1 wherein each of said side frame members is formed of two separate normally aligned upper and lower sections and further comprising pivot means supporting the upper end of said upper section, locking means at the lower end of said upper section for locking said lower end in alignment with said lower section, and a guide arm for each of said side frame members, said guide arm having one end pivotably mounted to said lower portion and another end slidably attached to said upper portion for maintaining said upper portion in any one of a plurality of angled positions.
Claim 10
Dependent Claim
18 words
The protective shutter device of claim 1 wherein said slats are made of lengths of extruded metallic material.
