Abstract
Abstract The board comprises a generally rectangularly shaped multi-layer panel section secured around its periphery in a rigid frame that is generally U-shaped in cross section. The panel section includes a plastic-coated metal layer forming the face of the board; and a plurality of bails are mounted on the back of the board for engagement by a plurality of hooks which are mounted on a wall so as to suspend the board therefrom. Two foldable arms are pivotally mounted on the frame adjacent its lower edge to extend parallel to the plane of the board when folded, and to extend normal to the board and to engage the wall and hold the board in an inclined position when unfolded. The frame prevents accidental dislodgment of the bails from the hooks when the board is moved to its inclined position.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
234 words
Apparatus for suspending from a vertical wall a scheduling board of the type having a generally rectangularly shaped, multi-layer panel section secured around its periphery in a rigid frame, comprising a plurality of bails, means mounting said bails on one side of said panel section to swing about a common axis extending adjacent and parallel to one edge of said panel section, a plurality of hooks secured to and extending from said wall releasably to register with and engage in said bails, thereby to suspend said board from said wall for limited pivotal movement about at least said common axis between a collapsed position in which the lower edge of said board remote from said one edge of said panel section is in proximate engagement with said wall, and an inclined position in which said lower edge of said board is spaced from said wall a distance greater than the upper edge thereof, and a plurality of support arms pivotally mounted each adjacent on end thereof on said frame adjacent said lower edge of the board for limited swinging movement between folded positions in which said arms are located adjacent and parallel to said panel section, when the board is in its collapsed position, and unfolded positions in which said arms extend tranverse to said panel section to have the opposite ends thereof engage said wall to hold the board in its inclined position.
Claim 2
Dependent Claim
234 words
Apparatus for suspending from a vertical wall a scheduling board of the type having a generally rectangularly shaped, multi-layer panel section secured around its periphery in a rigid frame, comprising a plurality of bails, means mounting said bails on one side of said panel section to swing about a common axis extending adjacent and parallel to one edge of said panel section, a plurality of hooks secured to and extending from said wall releasably to register with and engage in said bails, thereby to suspend said board from said wall for limited pivotal movement about at least said common axis between a collapsed position in which the lower edge of said board remote from said one edge of said panel section is in proximate engagement with said wall, and an inclined position in which said lower edge of said board is spaced from said wall a distance greater than the upper edge thereof, and a plurality of support arms pivotally mounted each adjacent on end thereof on said frame adjacent said lower edge of the board for limited swinging movement between folded positions in which said arms are located adjacent and parallel to said panel section, when the board is in its collapsed position, and unfolded positions in which said arms extend tranverse to said panel section to have the opposite ends thereof engage said wall to hold the board in its inclined position.
Claim 3
Dependent Claim
95 words
Apparatus as defined in claim 1, wherein said mounting means comprises a plurality of brackets each secured adjacent one end to said frame at said one side of said panel section, and pivotally connected adjacent its opposite end to one of said bails to support the latter for limited swinging movement about said common axis, and means limiting the swinging movement of each of said bails in one direction about said common axis and operative to maintain said bails in a plane inclined to said panel section, when the board is suspended from said hooks.
Claim 4
Dependent Claim
44 words
Apparatus as defined in claim 2, wherein said limiting means comprises one edge of said frame engagable with said bails to retain the latter in a plane inclined at an acute angle to said panel section, when the board is suspended from said hooks.
Claim 5
Dependent Claim
29 words
Apparatus as defined in claim 1, including means mounting said support arms on said frame for swinging movement about a second common axis parallel to the first-named common axis.
Claim 6
Dependent Claim
49 words
Apparatus as defined in claim 4, including means on each of said arms for limiting the swinging movement thereof in one direction about said second common axis, and operative to retain said arms substantially at right angles to said panel section, when said arms are in their unfolded positions.
Claim 7
Dependent Claim
85 words
Apparatus as defined in claim 5, wherein each of said arms comprises a rigid plate mounted adjacent one end thereof to pivot about a pin which is secured to said frame parallel to said first-named common axis, and engagable at its opposite end with said wall, when the arm is in its unfolded position, and a flange projects laterally from said arm adjacent said opposite end thereof to overlie and engage the rear face of said frame when the arm is in its unfolded position.
Claim 8
Dependent Claim
19 words
Apparatus as defined in claim 6, wherein said opposite end of each arm has a plastic cap secured thereover.
Claim 9
Dependent Claim
117 words
Apparatus as defined in claim 1, wherein said mounting means comprises a plurality of brackets each having one end thereof extending beneath and secured to one side of said U-shaped frame in confronting relation to said one side of said panel section, and projecting at its opposite end beneath the adjacent edge of said frame, and each of said brackets having formed on said opposite end thereof a rolled edge disposed coaxially of said common axis and rotatably housing therein a portion of one of said bails to support the latter of limited swinging movement about said axis, said adjacent edge of said frame being positioned to limit the pivotal movement of said bails in one direction.
Claim 10
Dependent Claim
38 words
Apparatus as defined in claim 8, wherein said bails are held by said adjacent edge of the frame in a plane inclined at an acute angle to said panel section when the board is suspended from said hooks.
Claim 11
Dependent Claim
15 words
Apparatus as defined in claim 9, wherein said hooks are secured directly to said wall.
Claim 12
Dependent Claim
22 words
Apparatus as defined in claim 9, wherein said hooks are secured to a board which in turn is secured to said wall.
Claim 13
Dependent Claim
32 words
Apparatus as defined in claim 1, including means mounting said support arms on said frame for swinging movement automatically to their unfolded positions, when the board is swung toward its inclined position.
Claim 14
Dependent Claim
55 words
Apparatus as defined in claim 1, wherein each of said bails is generally tirangularly shaped in configuration, and is disposed to have one leg thereof mounted for pivotal movement about said common axis, and is disposed to have the apex formed by the other pair of its legs releasably positioned over one of said hooks.
Claim 15
Dependent Claim
32 words
Apparatus as defined in claim 13, wherein each of said hooks has thereon opposed side edges which are inclined toward each other in the direction of the terminal end of the hook.
Claim 16
Dependent Claim
71 words
Apparatus as defined in claim 13, wherein each of said hooks comprises a vertical leg section disposed parallel to and spaced from said wall, and operative to support the terminal end of the associated hook above and in overlapping relation to said apex of the bail positioned on the hook, and said vertical leg section of each hook has a length substantially greater than the thickness of the bail positioned thereon.
