Abstract
.cndot. A wearable pen comprises a pen and a neck cord. The pen comprises a pen body and a ferromagnetic element. The neck cord comprises a loop-shaped cord, a permanent magnet, and a means for securely mounting the permanent magnet to the loop-shaped cord. The pen is capable of attaching to the neck cord by the magnetic attraction force in a single-hand operation when a user places the ferromagnetic element of the pen in proximity to the permanent magnet of the neck cord. The ferromagnetic element of the pen is capable of detaching from the permanent magnet of the neck cord in a single-hand operation when a user applies a force greater than the magnetic attraction force between the ferromagnetic element of the pen and the permanent magnet of the neck cord. This invention relates to pens, and the principal use of the invention is for operating a pen with a single hand.
Description
Description Title o Magnetically Attached inlearable Pen Technical Field o This invention relates to pens, more particularly to a wearable pen.
Background Art o There are many instances where it would be desirable to be able to provide a wearable pen which allows a user to magnetically attach a pen to a neck cord in a single-hand operation.
o A number of patents disclose wearable pens.
o U.S. Patent 6 394 677 discloses "Hanging pen and cord thereof". This prior art pen has a pen cap, and a penholder. The pen cap has a blocking cover with a loop cord for carryz_ng and an opening at the other end. The penholder provides a center. stick therein with a writing head of the center stick extending outwardly from a conical part at an end of the penholder. A magnetic ring is fixed in the pen cap. The conical part is made of magnet inducing material. The pen cap engages the penholder by way of the magnetic ring attracting the conical part when the conical part is inserted into the pen cap from the open end.
o These prior art arrangements do riot provide a wearable pen which allows a user to magnetically attach a pen to a neck cord in a single-hand operation. In addition, prior art wearable pens do not provide a feather in order to simulate a quill.
Description of the Invention o It is a primary object of the invention to provide a wearable pen which has a loop-shaped cord to be worn by the user around his/her neck.
o It is another object of the invention to provide a wearable pen in which a pen magnetically attaches to a neck cord in a single-hand operation by the user.
o It is another object of the invention to provide a wearable pen in which a pen detaches from a neck cord in a single-hand operation by the user.
o It is another object of the invention to provide a wearable pen to which a feather is attached in order to simulate a quill.
o A wearable pen comprises a pen and a neck cord. The pen comprises a pen body and a ferromagnetic element. The neck cord comprises a loop-shaped cord, a permanent magnet, and a means for securely mounting the permanent magnet to the loop-shaped cord. The pen is capable of attaching to the neck cord by the magnetic attraction force in a single-hand operation when a user places the ferromagnetic element of the pen in proximity to the permanent magnet of the neck cord. The ferromagnetic element of the pen is capable of detaching from the permanent magnet of the neck cord in a single-hand operation when a user applies a force greater than the magnetic attraction force between the ferromagnetic element of the pen and the permanent magnet of the neck cord.
Brief Description of the Figures in the Drawings o In drawings which illustrate embodiments of the invention:
o Figure 1 marked "Prior Art" is a sectional front view of a conventional wearable pen in an attached position;
o Figure 2 marked "Prior Art" is a sectional front view of another conventional wearable pen in an attached position;
