This present application claims priority to China Patent Application No. 202222698273.0 filed Oct. 13, 2022; the disclosure of which is incorporated by reference herein in its entirety.
The present invention relates to the field of panels and boards. More specifically, it relates to mechanisms for attaching and detaching panels and boards to fixed surfaces.
Conventionally, a drawing board (or blackboard) requires a matching easel to fix. When the easel is fixed, the user must carry the drawing board and the easel at the same time, which is very inconvenient, especially in the small space of the conference room. The easel occupies a large place, and it is also hard to store. Meanwhile, the easel is generally high-cost aluminum alloy shelf, which is inconvenient to move back and forth. Therefore, the present invention provides a detachable board to solve the shortcomings of the state of the art.
It is an objective of the present invention to provide a detachable board, which has the advantages of simple structure, rational design, small floor space, low in cost, and easy to store and move. To overcome the presented technical problems, the present invention provides the following technical solution: a detachable board comprises a body, a filling foam, and one or more mounting patches. The body includes a recessed area on the back of the body made by stamping process. The filling foam is arranged to be positioned within the recessed area, and with the inner walls and/or inner corners of the rim of the recessed area, to form one or more mounting slots. The shape of each of the mounting slots matches that of each of the mounting patches. In one embodiment, the filling foam is further configured to provide one or more notches on its edges that form part of each of the mounting slots.
During installation, the filling form is first installed in the recessed area, then the mounting patches are snuggly fitted into the mounting slots.
In accordance with one embodiment of the present invention, the thickness of the filling foam is same as the depth of the recessed area.
In accordance with one embodiment, there are four mounting patches. Each of the mounting patches has a thickness greater than the depth of the recessed area. Each of the mounting patches has a horizontal surface area (or volume) slightly larger than that of each of the mounting slots.
The cross-section of each of the plurality of mounting patches from top to bottom includes: a release film layer, an adhesive layer, and a substrate layer. The substrate layer is configured to be in contact with the body of the detachable board when the mounting patches are fitted within the mounting slots.
In accordance with one embodiment, the release film layer is provided with a shielding block. The shielding block is integrated to the release film layer in one-piece, and the shielding block can completely cover the protrusion.
In accordance with another embodiment of the present invention, the substrate layer is a memory foam or an elastic resin.
The present invention has the following advantages compared to the state of the art:
The present invention provides a detachable board. The detachable board includes a detachable board body, a filling foam, and one or more mounting patches. The overall structure is simple and the design is rational. The detachable board body is configured with a recessed area on its back by stamping process. The filling form is arranged and positioned in the recessed area and forms one or more mounting slots. During installation, the filling foam is to be installed in the recessed area, then the mounting patches are snuggly fitted into the mounting slots. Further, the thickness of the mounting patches is greater than the depth of the recessed area. When the detachable board is ready to be mounted onto a fixed surface, the mounting patches are protruding outward from the recessed area, which is convenient for the mounting operation. Meanwhile, the volume of each of the mounting patches is slightly larger than that of each of the mounting slots, providing a tight fitting, and thus strong gripping force, between the mounting patches and the mounting slots, so that the detachable board does not easily fall off when mounted. The notches, which allow the insertion of human fingers for handling the filling form, further ease the installation operation.
The cross-section of the mounting patch from top to bottom is: the release film layer, the adhesive layer, and the substrate layer. The release film layer is provided with a shielding cover, and the shielding cover can completely cover the notch corresponding to the mounting patch, which effectively prevent dust from entering the notch. At the same time, the release film layer can also protect the adhesive layer. Only the release film layer is needed to be peeled off during use. And the adhesive layer may paste onto a fixed surface, such as glass or a smooth wall. It is convenient to use in a small conference room. Compared to the traditional drawing board with the easel, the detachable board provides many practical utilities such as small floor space, low cost, and easy to move back and forth.
The present invention meets the diversified needs of users by printing text patterns on the erasable coating, and has strong practicability.
