A sports implement for obtaining autographs, having a core, a hole in the core having an open end and a closed bottom end, a housing disposed within the hole further comprising a latch, a spring, and a stop rim. The implement further includes a cap rotatably and slidably disposed within the housing comprising a first position wherein the cap compresses the spring toward the closed bottom end and a second position wherein the spring urges the cap against the stop rim, and a writing utensil removably coupled with the cap and rotationally coupled with the housing, further comprising a striker selectively interfacing with the latch.

The method and apparatus described herein allows for the automatic retraction and extension of the writing element of a bistable self-retaining writing instrument. The method and apparatus consists of a writing element that is joined to the end of a flexible tube or material. These are inserted through a longitudinal channel formed along the outer surface of the writing instrument and are anchored only at the end opposite the writing element. When the bistable self-retaining writing instrument transitions from a coiled to straight configuration the writing element is automatically exposed. Conversely, when pushed into its coiled configuration the writing element slides back into the channel and is thereby protected. The flexible tube or material may also act as a reservoir for a writing substrate such as ink.

An easy-to-hold off-axis pen has a pen head, a barrel, and at least one forefinger support. The pen head is irregularly shaped and hollow. The barrel is connected with the pen head and is hollow to accommodate a cartridge and to be held. A detachable clip fastener is strip-shaped whose two ends are respectively disposed on the pen head and an off-axis part of the barrel. One end of the detachable clip fastener can be pulled by fingers. The at least one forefinger support is disposed on a sidewall of the off-axis part to support and locate the forefinger during writing. The present invention can further include middle finger abutments disposed on the off-axis part and thumb anti-slip parts disposed on the barrel to make the easy-to-hold off-axis pen easy to grasp and anti-slip, and make users comfortable to grasp.

[Problems] An object of the present invention is to provide: thermochromic color-memory composition which effectively expresses a property of being capable of interchangeably memorizing and retaining colors and is thus applicable to various fields; and thermochromic memory microcapsule pigment encapsulating the same. [Means for Solution] Provided are thermochromic color-memory composition and thermochromic color-memory microcapsule pigment encapsulating the same, the thermochromic color-memory composition comprising: (a) a component composed of an electron-donating color-developing organic compound; (b) a component composed of an electron-accepting compound; and (c) a reaction medium which comprises an ester compound represented by the following Formula (1) and controls color reaction between the components (a) and (b): ##STR00001##
(wherein, R represents an alkyl group having 4 to 22 carbon atoms, a cycloalkylalkyl group having 5 to 12 carbon atoms, a cycloalkyl group having 4 to 8 carbon atoms or an alkenyl group having 4 to 22 carbon atoms; X represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms or a halogen atom; and n represents 0 or 1).

A writing instrument including: a body extending longitudinally along a central axis; a resilient element fixed to at least one portion of the body. The resilient element of the at least one portion of the body is in one piece and is made of at least partially amorphous metal alloy.

A modular magnet writing instrument and hobby tool comprises a plurality of permanent magnet segments and a writing cartridge. Each magnet segment is magnetized axially. An aperture extends longitudinally through the entirety of each magnet segment. The writing cartridge has an elongate body, which is sized for coaxial insertion within a magnet segment, or plurality of magnet segments, such that the magnet segments are in sliding engagement with the elongate body. In operation, different combinations of magnet segments can be axially positioned on the elongate body, in a variety of like-pole and unlike-pole interactions, to produce a plurality of writing and hobby tool configurations.

A magnetized writing and amusement device. The device having a first end and a second end. Each of the ends having a magnet embedded with the interior. The magnetics allowing for the coupling of multiple devices together. The first end functions as a cap for the device and conceals a writing implement located within the internal structure of the device.

A writing instrument includes a shaft barrel and a grip provided at part of the shaft barrel. The grip has a cylindrically shaped inside shaft part and a cylindrically shaped outside shaft part arranged at the outside of the inside shaft part, thinner than the inside shaft part, and made of a nonviscoelastic plastic. A space part is provided between the inside shaft part and the outside shaft part.
