Magnetic multilayer pushpin board
Provided is a multilayer pushpin board for retaining and displaying messages that is capable of accommodating both pushpins and magnets. The multilayer message board includes a support substrate preferably made from an elastically recoverable elastomeric material that can be pierced by and releasably retain the spike of a pushpin. A composite sheet made from magnetic attractable particles dispersed into a binder material is secured to the support substrate. The composite sheet is thin and soft enough to allow the spike of a pushpin to penetrate therethrough. Preferably, a cover sheet is laid over and secured to the composite sheet, the cover sheet preferably being made of elastically recoverable elastomeric material. The cover sheet is thin enough to avoid interfering with the magnetic attraction associated with the composite sheet.
1 . A multilayer pushpin board adapted to temporarily retain at least one magnet and to receive at least one pushpin spike having a length, said board comprising:
a support substrate, said support substrate comprising a surface; and
a piercable composite sheet comprising a magnetic attractable material dispersed into a binder material, the composite sheet overlaid on at least a portion of the surface of the support substrate, whereby said composite sheet is adapted to be pierced by said pushpin spike, said pushpin spike being received in said support substrate, and whereby the composite sheet is adapted to temporarily retain the magnet.
2 . The multilayer pushpin board of claim 1 wherein the support substrate comprises a recoverable elastomeric material.
3 . The multilayer pushpin board of claim 2 , wherein the recoverable elastomeric material comprises foamed ethyl vinyl acetate.
4 . The multilayer pushpin board of claim 1 further comprising a cover sheet overlaid on at least a portion of the composite sheet.
5 . The multilayer pushpin board of claim 4 , wherein the cover sheet is flexible.
6 . The multilayer pushpin board of claim 4 , wherein the cover sheet comprises at least one of the following: a recoverable elastomeric material, a fabric, or a paper.
7 . The multilayer pushpin board of claim 6 , wherein the support substrate and the cover sheet are comprised of the same recoverable elastomeric material.
8 . The multilayer pushpin board of claim 4 , wherein the cover sheet has a thickness of about 2.5 millimeters or less.
9 . The multilayer pushpin board of claim 8 , wherein the cover sheet has a thickness of about 1 millimeter or less.
10 . The multilayer pushpin board of claim 4 , wherein at least two of the composite sheet, the cover sheet, and the support substrate define respective peripherial edges of corresponding shape.
11 . The multilayer pushpin board of claim 1 , wherein the magnetic attractable material comprises ferrometallic particles and the binder material comprises a polymeric material.
12 . The multilayer pushpin board of claim 1 wherein the binder material comprises at least one of chlorinated polyethylene or polyvinyl chloride.
13 . The multilayer pushpin board of claim 1 , wherein the composite sheet has a thickness of about 2.0 millimeters or less.
14 . The multilayer pushpin board of claim 13 , wherein the composite sheet has a thickness of about 0.5 millimeters or less.
15 . The multilayer pushpin board of claim 1 , wherein the composite sheet is flexible.
16 . The multilayer pushpin board of claim 1 , further comprising a dry-erase surface.
17 . The multilayer pushpin board of claim 16 , wherein the dry-erase surface is disposed along at least a portion of at least one of said surface of the support substrate and said composite.
18 . The multilayer pushpin board of claim 1 , further including a mounting arrangement for coupling the board to a support surface.
19 . The multilayer pushpin board of claim 1 , further comprising a frame, at least one of the support substrate or the piercable composite sheet being at least partially disposed in said frame.
20 . The multilayer pushpin board of claim 19 , wherein the support substrate is removably disposed in said frame.
