Magnetic pin for holding paper onto a ferromagnetic surface

Abstract

This device is composed of two pins. Each pin is made of plastic and a piece of magnetic that has opposite magnetic polarity facing each other. The pin can be used as a single unit where it can hold stationery such as papers, envelopes or small pamphlet to a ferromagnetic surface such as metal office cabinet, metal chalk board, refrigerator door or anywhere ferromagnetic surface exist. When used as one single unit the paper or stationery have some degree of rotational freedom and will self-center itself with the heaviest side down. It can also be attached to a center of a personal business card or credit card and be spun like a top vertically, horizontally or upside down on a ferromagnetic surface. However, when used as two individual pin to attach the stationery to a ferromagnetic surface such as metal office cabinet, metal chalk board, refrigerator door or anywhere ferromagnetic surface exist the stationeries will have no degree of rotational freedom and it will be fixed into position.

Claims

1. A magnetic device for holding sheet material, comprising: a pair of pin members configured to be used as a single unit or separately to hold sheet material there between to a ferromagnetic surface; said pair of pin members comprising a top and bottom pin member; said top pin member being constructed of a solid material and having cylindrical body portion having a planar lower face defining a socket extending from the planar lower face in which a first magnet is fixedly seated such that a magnet surface of said first magnet is coplanar with the planar lower face; said top pin further having an elongated grip portion defined by a neck and head portion extending from said cylindrical body portion; said bottom pin member being constructed of a solid material and having cylindrical body portion having a planar upper face defining a socket extending from the planar upper face in which a second magnet is fixedly seated such that a magnet surface of said second magnet is coplanar with the planar upper face; said bottom pin further having an bulbous grip portion extending radially from said cylindrical body portion and terminating in a convex face; wherein when employed as a single unit, the top and bottom pin members are magnetically connected to one another and, concurrently, the convex face of the bottom pin member is configured to be magnetically connected to a ferromagnetic surface having any orientation while maintaining rotational freedom of the device thereon; and wherein when employed separately the planar surfaces of the top and bottom pin members are configured to statically secure sheet material to a ferromagnetic surface.

DETAILED DESCRIPTION OF THE INVENTION

(10) A magnetic pin for holding paper onto a ferromagnetic surface (Flying Pin). This device is composed of a top pin member (10) and a bottom pin member (20).

(11) The top pin member is constructed of a solid plastic material and has cylindrical body portion having a planar lower face defining a socket extending from the planar lower face in which a first magnet (14) is fixedly seated such that a magnet surface of said first magnet is coplanar with the planar lower face. The top pin further has an elongated grip portion defined by a neck (12) and head (11) portion extending from said cylindrical body portion (13).

(12) The bottom pin member is constructed of a solid plastic material and has a cylindrical body portion having a planar upper face defining a socket extending from the planar upper face in which a second magnet (24) is fixedly seated such that a magnet surface of said second magnet is coplanar with the planar upper face. The bottom pin further having a bulbous grip portion (21) extending radially from said cylindrical body portion and terminating in a convex face.

(13) The device can be used as a single unit where top and bottom pins hold stationery such as papers (30), envelopes or small pamphlets to a ferromagnetic surface (40), such as metal office cabinet, metal chalk board, refrigerator door or anywhere ferromagnetic surfaces exist (FIGS. 2A-3B). When used as a single unit, the device will have some degree of rotational freedom and will self-center itself with the heaviest side of the bottom pin down. It can also be attached to a center of a personal business card or credit card and can be spun it like a top vertically, horizontally, or upside down on a ferromagnetic surface.

(14) The device can also be used as two individual pins to attach the stationery to a ferromagnetic surface, such as a metal office cabinet, metal chalk board, refrigerator door or anywhere ferromagnetic surfaces exist. In this arrangement, the stationery will have no degree of rotational freedom and it will be fixed into the position in which it was placed (FIGS. 4A-4B). In addition, it can be used as a set of two pins to attach a piece of paper onto a ferromagnetic surface. In this arrangement, the paper will have no degree of freedom and offers the advantage of being able to be removed or place with one hand onto a ferromagnetic surface. The magnetic pin holds the paper or stationery or pamphlet through friction and magnetic power and the papers or stationery or pamphlet that it is holding. In addition, it does not make holes onto the surface that it is attached to. Another advantage of the magnetic pin allows the user to remove the paper or stationery or pamphlet with one hand without have the stationary or the pin to fall onto the floor (FIGS. 5A-5B).
