The present inventive subject matter relates to a magnetic display system that may be connected to a surface. More particularly, the present inventive subject matter relates to a magnetic display system with a fabric top layer and magnetic back layer, which may be connected to a surface such as a wall, chalkboard, or dry erase board.
There are many well-known teaching aids available in the prior art. These include chalkboards, dry erase boards, flannel cloths, wood blocks, plastic blocks, magnetic blocks and foam-like blocks. Each of these teaching aids have advantages and disadvantages, including cost, size, and the availability of these devices to teachers and students. Some of these teaching aids can be intimidating to students because of their size and/or their location in a given room. Further, some of these aids include heavy, messy, expensive, and difficult to use components.
Educators have always desired obtaining and using teaching aids that are readily and easily available, as well as obtaining teaching devices which can be readily and easily available and used by students, in particular with younger more impressionable students. It is thought that the use of teaching devices that are easily handled and manipulated by the teacher and the students can enhance learning by, inter alia, encouraging participatory learning processes by students.
However, encouraging students to participate in learning exercises can sometimes be a daunting task to many educators. Moreover, many younger students, such as those students in pre-kindergarten, kindergarten, first, second, and third grades, can be intimidated easily by having to approach an education device, such as a chalkboard or dry erase board and having to perform a desired task on the device.
In an attempt to make learning easier and fun for these younger students, flannel boards have been created. Flannel boards typically consist of a board covered with a flannel material in which flannel cut-outs can be placed thereon for education and illustration purposes. However, many of these boards only have a solitary use, which make them somewhat undesirable to many educators and school systems. For example, a flannel board may be great for interactive learning exercises, however, if an educator wants to lecture before a class, using a dry erase board or chalkboard is usually more efficient.
Due to rising education costs, and dwindling budgets, schools are forced to cut back and prioritize how money is spent every year. Thus, for many schools, the ability to purchase a standard chalkboard or dry erase board for a classroom is all the school can budget for. Such other preferable learning and education devices, such as an interactive flannel board, may not make the budget cuts.
Further, many schools and classrooms are becoming increasingly over populated. Many times, teachers barely have enough space for a standard chalkboard or dry erase board, let alone the space for a separate flannel board.
Thus, it is highly desirable to condense the amount of learning and education devices needed, while also reducing the cost and space restrictions put in place by schools. Further, it is highly desirable to produce an easy to manipulate and light weight, teaching and education device, which can increase the learning of students, in particular that of pre-kindergarten, kindergarten, and early elementary grade level students.

More particularly, the present inventive subject matter relates to a display system that includes a top layer, a middle section connected to the top layer, and a back layer connected to the middle section, wherein the top layer includes a fabric material, and the back layer includes a magnetic material.
The present inventive subject matter further relates to a process for manufacturing a display device. The process includes the steps of attaching a top layer to a back layer by connecting a middle section to both the top layer and the back layer, wherein the top layer includes a fabric, and the back layer is a magnetic material.
In another embodiment, the fabric material of the display system is selected from the group consisting essentially of flannel, felt, cotton, polyester, nylon, hook and loop material, and velvet.
In a further embodiment, the connecting middle section of the display system is an adhesive. In yet a further embodiment, the adhesive is an acrylic containing pressure sensitive adhesive.

It is understood that the above descriptions are not, and should not be, limited solely to that explicitly shown in the figures. In the embodiments illustrated above, the magnetic display systems are constructed having three layers, however, it would be well within the scope and breath of this disclose to construct a magnetic display system having less than or more than three layers.
The top layer of the magnetic display system can be constructed in part, or in whole, from any suitable material, including, but not limited to, fabric(s), textile(s), metal(s), alloy(s), wood(s), porcelain, polymer(s), elastomer(s), or combinations thereof. In some embodiments the top layer can contain at least one fabric, textile, metal, alloy, wood, porcelain, polymer, or elastomer. In one embodiment the top layer of the magnetic display system is constructed in part, or in whole, from a pliable, soft material such as a fabric or textile material. Non-limiting examples of suitable fabrics or textile materials include, but are not limited to, flannel, felt, nylon, cotton, polyester, hook and loop material, and velvet. Non-limiting examples of other materials that can be utilized include, but are not limited to, latex, polyvinyl chloride, silicone, polyvinyl alcohol, chlorinated polyethylene resins, thermoplastics, and thermoset polymers. In another embodiment of the present inventive subject matter, the top layer comprises a fabric or textile, such as flannel or felt, which can hold a static electricity charge to aid in allowing characters to be placed and temporarily secured thereon.
The connecting middle section can be any suitable chemical composition, agent, mixture, emulsion, or adhesive, or mechanical device, which connects the top layer to the back layer. If the connecting middle section comprises a chemical substance, the chemical substance can be present in a continuous, or non-continuous, porous, or non-porous layer. Further, if the middle section comprises a chemical substance, the chemical substance can be present in separate or joined, connected or unconnected lines, dots, or other patterns.

Further, the characters can include at least one magnetic, or magnetizable material to aid, promote, and/or necessitate the characters to attach to the top layer of the magnetic display system.
In certain embodiments of the inventive subject matter, a magnetic display system, including all of the embodiments described herein, is attached to a surface such as a chalkboard, a dry erase board, or other magnetic surface by placing the back layer of the magnetic display system flush against the surface to which the display system is desired to be attached, and remains connected to the surface by magnetic force. After placing the back layer flush against the surface to which the magnetic display system is to be attached, the top layer will be planar to the surface upon which the display system is attached. Characters, as previous described and depicted, can be attached to the top layer for teaching or learning exercises.
