This invention relates generally to the field of clothing accessories. More specifically, this invention involves a magnetic collar stud assembly for securing a shirt collar in place. In a preferred embodiment, the magnetic collar stud assembly includes two magnets of opposite polarities where one magnet is positioned inside the shirt and the other magnet is positioned outside the collar.
Various accessories currently exist for holding the collar of a traditional button-down shirt in place. One of the most popular accessories is a pair of collar stays. Collar stays are long, flat and typically plastic structures that are positioned inside a collar to hold the collar in place.
An additional accessory for holding a collar in place is a pair of traditional collar studs. Collar studs generally include a decorative side and an attachment side. In the most common example of a collar stud, the decorative side and the attachment side are connected by a thin rod. The collar studs generally act by forcing the decorative side through a slit in the inner collar of a shirt and then through a slit in the outer collar of the same shirt. The thin rod is positioned inside the two slits and the decorative side and the attachment side hold the collar against the shirt in a fixed position.
The traditional collar studs are limited for several reasons. First, the traditional collar studs require a pair of slits in the shirt collar for inserting the thin rod. Thus, traditional collar studs cannot be worn on shirts that do not have specially made slits in the collar. Second, traditional collar studs are limited to a fixed position—the position of the slits. It is not possible to position traditional collar studs other than at the slits without forming additional slits on the collar, which would be unsightly.
Magnetic elements have previously been used in the clothing field and for the specific use of keeping a shirt collar aligned and fastened. U.S. Pat. No. 7,409,730 to Boos (hereafter “Boos”) discloses a Method and Apparatus for Keeping a Shirt Collar Aligned and Fastened Magnetically. Boos discloses a metal collar stay insertable into a conventional collar stay pocket and a magnet, magnetically attachable to the collar stay through the shirt front, for holding the collar in the selected position. Boos further discloses one or more detents in the collar stay for preventing relative longitudinal movement between the magnet and the collar stay. The magnet disclosed in Boos is flat and may be difficult to handle with one's fingers.
U.S. Pat. No. 5,974,634 to Eisenpresser (hereafter “Eisenpresser”) discloses a decorative multi-use magnetic button construction which includes a decorative shell having a cavity containing a first magnet. The first magnet contacts a base of the construction and the base contacts a garment. The construction is held in place on the fabric by attraction to a second magnet on the opposite side of the magnet. The device of Eisenpresser lacks a mechanism for holding the magnets in place beyond their inherent magnetic attractive forces. Further, similar to the device of Boos, the Eisenpresser device is flat and may be difficult to handle with one's fingers.
In view of the deficiencies and drawbacks relating to securing a collar in place, it is a primary object of the present invention to provide a magnetic collar stud assembly.
A further object of the present invention is to provide an improved magnetic collar stud assembly that is more secure than existing devices for securing a shirt collar.
In summary, there is provided in a preferred embodiment of the present invention A collar stud assembly for selectively securing a collar to a shirt, comprising an outer decorative assembly, the outer decorative assembly including a frame and a first magnet having a first polarity; a second magnet, the second magnet being spherical and having a second polarity opposite to the first polarity; wherein the frame includes an indent, the indent adapted to match the curvature of the second spherical magnet.
With reference to
The outer assembly 105 includes a frame 115, a magnet 120 having a first polarity, and a decorative cover 125. The frame 115 further includes an indent 130 and a cavity 135. The cavity 135 is sized and shaped to contain the magnet 120 and the decorative cover 125. Preferably, the magnet 120 is positioned inside the cavity 135 and the decorative cover 125 is fixed to the frame 115 thereby securing the magnet 120 inside the cavity 135.
As illustrated in
The spherical magnet 110 is held in a fixed position relative to the frame 115 by the indent 130. The indent 130 is shaped and sized to match the curvature of the spherical magnet 110. As best shown in the cross-section view of
The positioning of the portions of the outer collar 210 and the inner collar 220 in the indent 130 creates a shadow indent 230 in the collars. See
In the preferred embodiment, the frame is cylindrical and includes a frame base 117. The frame base represents to the bottom side of the frame, i.e. the side furthest from the decorative cover 125. In the preferred embodiment, the indent 130 has a depth which is one third the width of the frame base.
The magnetic collar stud assembly 100 is removed from the shirt 200 by griping the spherical magnet 110 in between one's thumb and index finger and griping the outer assembly 105 between the thumb and the index finger of one's opposite hand. The spherical shape of the spherical magnet 105 make the spherical magnet 105 easier to grip and thus easier to remove and attach.
As illustrated in
Both the spherical magnet 110 and the magnet 120 are preferably constructed of neodymium magnets in the N42 to N52 range. Neodynium magnets are made from an alloy of neodymium, iron, and boron to form an Nd2Fe14B tetragonal crystalline structure. Neodynium magnets are one of the strongest types of permanent magnet currently available. It has been found that using strong magnets such as neodymium magnets prevent the collar stud assembly from detaching during use.
