Device for combined support, display, exhibition, reading and writing of flat objects.

Abstract

The invention relates to a device for combined support, display, exhibition, reading and writing of flat objects, which consist of two separate essentially flat and plane sheet members ( 10, 20 ), one of which ( 10 ) is made up of an elongated horizontal base part which on its upper surface in the longitudinal direction has a coherent array of transverse serrated steps ( 13 ) and at least one transverse slit-formed recess ( 11 ), whereas the other member ( 20 ) is made up of an elongated mainly vertical erected support part having a sheet thickness which fits into the width of the transverse slit-formed recess ( 11 ) in the base part ( 10 ) when assembling the two parts, wherein the transverse slit-formed recess ( 11 ) is provided at the top of a transverse projecting elevation ( 12 ) on the upper surface at one end of the horizontal base part ( 10 ) thus forming a selected definite angle between the facing surfaces of the base part ( 10 ) and the vertical part ( 20 ) when the parts are assembled. Both ends ( 21, 22 ) of the vertical support part ( 20 ) can be used for introduction into the slit formed recess ( 11 ) in the base part ( 10 ) to form different selected angles between the surfaces of the plate members ( 10, 20 ) facing each other.

1 . A device for combined support, display, exhibition, reading and writing of flat objects, which consist of two separate essentially flat and plane sheet members ( 10 ,  20 ), one of the sheet members being an elongated horizontal base part ( 10 ) having an upper surface in the longitudinal direction which has a coherent array of transverse serrated steps ( 13 ) and at least one transverse slit-formed recess ( 1 ), and another one of the sheet members being an elongated mainly vertical erected support part ( 20 ) having a sheet thickness which fits into the width of the transverse slit-formed recess ( 11 ) in the horizontal base part ( 10 ) when assembling the two parts, wherein said transverse slit-formed recess ( 11 ) extends essentially vertical from the top of a transverse projecting elevation ( 12 ) provided on the upper surface at one end of the horizontal base part ( 10 ) so that a selected definite angle between the facing surfaces of the horizontal base part ( 10 ) and the vertical support part ( 20 ) is formed when the parts are assembled. 
     
     
         2 . A device according to  claim 1 , wherein the transverse serrated steps ( 13 ) on the upper surface of the horizontal base part ( 10 ) are projections having a substantial vertical front face facing towards the position of the transverse projecting elevation ( 12 ) on the horizontal base part ( 10 ) and a backwards sloping rear surface. 
     
     
         3 . A device according to  claim 1 , wherein the total area of the upper surface of the horizontal base part ( 10 ) or a major part thereof is covered with a coherent array of transverse serrated steps ( 13 ) except for a small length ( 16 ) corresponding to about the extent of two to three steps nearest the front face of the elevation ( 12 ) at the end of the horizontal base part ( 10 ). 
     
     
         4 . A device according to  claim 1  wherein an end part of the vertical support part ( 20 ) which projects down into the slit-formed recess ( 11 ) is faintly curved in the longitudinal or cross direction, preferably in the cross direction, so that said end part is firmly squeezed in the slit-formed recess ( 11 ) even though the width of the slit formed recess is slightly greater than the thickness of the vertical support part. 
     
     
         5 . A device according to  claim 1 , wherein the slit-formed recess ( 11 ) in the transverse projecting elevation ( 12 ) on the upper surface of the horizontal base part ( 10 ) may be weakly wedge-shaped in cross section so that the slit-formed recess is broadest at top and narrowest at bottom or vice versa. 
     
     
         6 . A device according to  claim 1 , wherein the end part ( 21 ) of the vertical support part ( 20 ) is substantially straight in the longitudinal direction and another end ( 22 ) of the vertical support part is provided with a distinct stronger curvature or bending ( 23 ) in the longitudinal direction of the vertical support part ( 20 ). 
     
     
         7 . A device according to  claim 6 , wherein the distinct curvature or bending ( 23 ) starts sufficiently near the another end ( 22 ) of the vertical support part ( 20 ) to cause a tight squeezing in the slit-formed recess even when a thickness of the vertical support part ( 20 ) is slightly smaller than a width of the slit formed recess ( 11 ). 
     
     
         8 . A device according to  claim 1 , wherein the transverse projecting elevation ( 12 ) on the upper surface the horizontal base part ( 10 ) also is provided with a transverse horizontal side slit recess ( 15 ) in the front face and at the bottom of the elevation ( 12 ) having a width which fits tight to sheet thickness of the vertical support part. 
     
     
         9 . A combined device according to  claim 1 , wherein the horizontal base part and the vertical support part are produced of different materials so that the horizontal base part ( 10 ) is made of a heavier material, selected from the group of stainless steel, aluminum, an aluminum alloy and other metal alloys, whereas the vertical support part ( 20 ) is produced of a lighter material. 
     
     
         10 . A combined device according to  claim 9 , wherein the horizontal base part ( 10 ) is extruded aluminum which preferably has an anodized surface which optionally may be colored, and the vertical support part ( 20 ) is ABS plastic that may be clear or transparent, or colored with any desired shade. 
     
     
         11 . A combined device according to  claim 9 , wherein the vertical support part ( 20 ) is made of plastic.
