Abstract
Abstract In a planning board of the kind having a foil surface adapted to have planning symbols attached thereto by a self-adherent effect, this effect being also utilized for the purpose of assembling the planning board from individual board elements. For this purpose, each element has a smooth surface at least along a margin of its reverse side so that it may be attached self-adherently to the surface of another like element. The resulting planning board can be folded like a book, e.g. for accommodation in a briefcase and provision may also be made for attaching it to a wall-mounted strip by the same self-adherent effect. Provision may also be made for the planning board to accommodate a card strip (e.g. bearing a notice) between two foil surfaces making up the planning board.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
122 words
A planning board comprising, in combination, a plurality of substantially planar planning board elements each having a front surface and a rear surface, said front surface formed by a soft, smooth foil having the property of detachably adhering by vacuum forces to a similar smooth surface pressed thereon by adherent interaction between the overlying surfaces, said rear surface having a smooth surface along at least a marginal portion to permit two or more planning board elements to be detachably interconnected in mutually adhering engagement by pressing together in overlying relationship said smooth marginal portion on one planning board element and a corresponding portion of the foil surface on another element to form a planning board from said plurality of planning board elements.
Claim 2
Dependent Claim
122 words
A planning board comprising, in combination, a plurality of substantially planar planning board elements each having a front surface and a rear surface, said front surface formed by a soft, smooth foil having the property of detachably adhering by vacuum forces to a similar smooth surface pressed thereon by adherent interaction between the overlying surfaces, said rear surface having a smooth surface along at least a marginal portion to permit two or more planning board elements to be detachably interconnected in mutually adhering engagement by pressing together in overlying relationship said smooth marginal portion on one planning board element and a corresponding portion of the foil surface on another element to form a planning board from said plurality of planning board elements.
Claim 3
Dependent Claim
14 words
A planning board according to claim 1, wherein the soft smooth foil is washable.
Claim 4
Dependent Claim
25 words
A planning board according to claim 1, wherein said elements are in the form of cardboard elements which are covered by said soft, smooth foil.
Claim 5
Dependent Claim
27 words
A planning board according to claim 1, wherein said elements can each be closed up like a book along a line extending substantially centrally of the element.
Claim 6
Dependent Claim
74 words
A planning board in accordance with claim 1, wherein each of said planning board elements is provided with a marginal lip along at least two adjoining sides thereof to serve as self-adhering portions on said planning board elements to secure said planning board elements together, said self-adhering marginal lips being disposed adjacent the surface of said planning board element to which a plurality of planning symbols may be detachably applied in a self-adhering manner.
Claim 7
Dependent Claim
31 words
A planning board according to claim 5, wherein the marginal lips are formed by a region which is covered by said soft, smooth foil and which is bounded by weld seams.
Claim 8
Dependent Claim
62 words
A planning board according to claim 6, wherein a strip is provided adjacent the region which is covered by said soft, smooth foil and adapted to have planning symbols pressed thereonto, the strip being formed by a first and a second said foil, said foils separably adhering together in such a manner as to enable a paper strip to be insertable therebetween.
Claim 9
Dependent Claim
20 words
A planning board according to claim 7 wherein said foils which form the strip are bounded by a weld seam.
Claim 10
Dependent Claim
36 words
A planning board in accordance with claim 5 wherein said marginal lips are formed on each of said planning board elements along adjacent marginal edge portions defining the length and width of said planning board element.
Claim 11
Dependent Claim
54 words
A planning board in accordance with claim 5 wherein said marginal lips extend throughout an area on said planning board element front surface and a longitudinally and transversely extending weld seam on said planning board element for separating the area of said marginal lips from the remaining surface portion of said planning board element.
Claim 12
Dependent Claim
38 words
A planning board in accordance with claim 1 including a foil strip having an adhesive on one surface and having a smooth other surface for self-adhering engagement with the rear surface of one of said planning board elements.
Claim 13
Dependent Claim
44 words
A planning board in accordance with claim 1 wherein at least one of said planning board elements is provided with an opening between said front and rear surfaces along one marginal edge and a strip removably positioned within said opening adjacent said marginal edge.
