A RECTANGULAR-SHAPED BOARD OF FLAT CORRUGATED MATERIAL WITH AN IMPROVED EDGE STRUCTURE This is a continuation of application Ser. No. 185,288, filed Sept. 30, l971,'now abandoned.
BACKGROUND OF THE INVENTION The present invention relates generally to improvements in pattern boards and the like constructed from laminated material and the like and, more particularly to an improved pattern board made from corrugated material which is provided with edges formed in a manner to reduce injury due to handling the board.
It has been a general practice to manufacture work boards having printing or illustrations on one side thereof such as pattern boards, chart boards and the like from laminated material such as corrugated board. Corrugated board material is especially suited for this application because it is receptive to printing; easy to penetrate with pins or tacks and is lightweight and inexpensive to manufacture. While such boards formed of corrugated cardboard have served the general purpose for which they are applied, they have not proved entirely satisfactory under all conditions of service for the reason that there is a danger of injury to the individual using the board because of the sharp edges formed on the periphery of the work boards. One solution to this problem has been to apply a tape-like material around the periphery of the work board to cover the sharp edges. Although this method satisfactorily protects against injury, his time consuming and expensive to apply to the board.
One purpose of the present invention is to provide a work board which is constructed from a corrugated board material and does not have sharp edges on its periphery which may injure the hands of the user. To attain this, the present invention utilizes a specially constructed improved edge in which one of the liner sheets of the corrugated material extends over and is attached to the other side of the board thus covering the edge of the corrugated material.
OBJECTS OF THE INVENTION One object of the present invention is the provision of a work board with an improved protective edge thereon.
Another object of the present invention is the provision of a work board with an improved protective edge thereon, which is simple and inexpensive to manufacture.
Other objects and many of the attendant advantages of this invention will be readily appreciated by those of ordinary skill in the art as the same become better understood by reference of the following detailed description when considered in connection with the accompanying drawings, wherein:
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 illustrates a plan view of the improved work board of the present invention, showing an example of printing on one side thereof;
FIG. 2 is a perspective view of an improved work board shown in the folded condition;
FIG. 3 is an enlarged sectional view of the board taken transverse to the direction of fluting; and
FIG. 4 illustrates an enlarged sectional view of the Y work board taken on line 4-4 of FIG. 1 looking in the direction of the arrows.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, wherein like reference characters designate like or corresponding parts throughout the several views, there is shown in FIG. 1 a work board 10 of a rectangular shape which in this case is constructed from a corrugated cardboard material to give the board sufficient rigidity and strength when in use. The front side of this board may be pro vided with printing 12, which in FIG. 1 is shown as a grid but could be a chart, graph, map or the like. The board can also be creased along parallel fold lines 14 so that the board may be folded for conveneient storage as shown in FIG. 2.
Turning now to FIG. 3, there is shown an enlarged sectional view illustrating the corrugated material from which the board is constructed. This corrugated material is constructed with paper material front and rear liners l6 and 18, respectively, which are bonded or connected together by a paper material central backing medium or web 20 which is alternately connected between the front and rear liners to form a wavelike or fluted cross-section. The front liner 16 is formed from a material to which it is easy to apply printing 12 while the rear liner 18 can be of any suitable paper material. It can be seen by constructing the board 10 from corrugated material as shown in FIG. 3 that pins or tacks can be easily inserted into the board to hold various items in position thereon. It is contemplated that other types of materials could be used which would easily allow the insertion of pins therein such as a paper material with a styrofoam backing, but it is believed convenient that at least one sheet of material be used to provide a surface for the printing 12 to be placed thereon and that some form of backing be provided to give the sheet rigidity.
It is obvious from the fact that since the board 10 is constructed from laminated sheet materials that, when the periphery of the board 10 is formed by ordinary cutting, a sharp and sometimes dangerous edge of the liners will be present. To prevent the formation of this edge the present invention utilizes, as can be seen in FIG. 4, an extension 26 on the front liner material 16, which is bent back over the edge of the board and is sealed at 28 to the rear liner 18 by a suitable adhesive such as disclosed in the patent to Wagers et al., US. Pat. No. 3,563,843, issued Feb. 16, 1971. In this manner, the edges of the liner material and medium are covered.
For purposes of appearance, the front liner has been extended, but it is obvious that the rear liner could also be extended, or the front liner extended on some edges and the rear liner on the other edges. It is also apparent that the invention could be utilized on laminated materials having as few as one liner sheet with backing medium thereon. In this case, the liner would extend around the backing medium and be attached to the opposite side. Obviously the invention could be utilized on boards with other exterior shapes and on less than all of the sides of each board as dictated by the shape and method of manufacture.
Various modifications are contemplated in view of the above disclosure and may obviously be resorted to by those or ordinary skill in the art without departing from the spirit and scope of the invention as hereinafter defined by the appended claims.
What is claimed and desired to be secured by United States Letters Patent is:
1. A workboard comprising:
a rectangular-shaped board of flat corrugated mateby third and fourth elongated parallel spaced edges parallel to the length of the corrugations, a plurality of spaced creased areas extending across said board parallel to the length of said corrugations whereby said board can be folded for storage,
protective edge means on the periphery of said board along said third and fourth edges, said protective edge means comprising an extension of said first liner beyond said corrugated web and said second liner, said extension being folded over and around both corners of said corrugated web and along the outside of said second liner and,
an adhesive material attaching said extension to said second liner.
