Abstract
A clip for a writing instrument has an external biasing mechanism separate from the connection of the clip to the writing instrument to avoid permanent deformation or breaking of the clip arm and wear on the writing instrument body. The biasing mechanism is a coil spring mounted on the clip arm between two supports for compression and flexion when the clip arm is pulled away from the side of the writing instrument.
Claims24
A clip for a writing instrument comprising:
- a clip support rigidly extending from the writing instrument and defining a hole at a free end of the clip support;
- a clip arm, an upper end of the clip arm passing through the hole of the clip support;
- fastening means for securing the clip arm to the clip support through the hole;
- biasing means held on the clip arm for biasing the clip arm toward a resting position adjacent the writing instrument, the biasing means being distinct from the clip support and external to the writing instrument, the clip arm having a use position spaced from the writing instrument for clipping the writing instrument to an object against the bias of said biasing means.
A clip for a writing instrument comprising:
- a clip support rigidly extending from an end of the writing instrument, the clip support having a free end defining an opening therethrough;
- a clip arm having a threaded upper end and a stepped portion spaced apart from the threaded upper end, the clip arm held in the opening having the threaded upper end located on a top side of the clip support opening and the stepped portion located on a bottom side of the clip support opening;
- a coil spring fitted around the clip arm, a coil spring lower end resting against the stepped portion, a coil spring upper end resting against a bottom surface of the clip support;
- a fastener secured to the threaded end for pivotally holding the clip arm in the clip support opening, wherein the clip arm may be pivoted from a resting position under a force and the coil spring biases the clip arm toward the resting position.
A clip for a writing instrument comprising:
- a clip support rigidly extending from the writing instrument and defining a hole at a free end of the clip support;
- a clip arm, an upper end of the clip arm passing through the hole of the clip support;
- fastening means for retaining the clip arm in the hole of the clip support;
- and
- biasing means mounted on the clip arm for biasing the clip arm toward a resting position adjacent the writing instrument by compression or flexion in a direction generally corresponding to a longitudinal axis of the clip arm, the biasing means being distinct from the clip support and external to the writing instrument, the clip arm having a use position spaced from the writing instrument for clipping the writing instrument to an object against the bias of said biasing means.
A clip for holding a writing instrument to an object, the clip comprising:
- an elongated clip arm extending alongside the writing instrument in a longitudinal direction;
- support means for pivotally connecting the clip arm to the writing instrument in spaced relation adjacent the writing instrument;
- and
- biasing means mounted on the clip arm for biasing the clip arm toward a resting position adjacent the writing instrument by compression or flexion in the longitudinal direction, the biasing means being distinct from the support means and external to the writing instrument, the clip arm having a pivoted use position spaced from the writing instrument for clipping the writing instrument to an object against the bias of said biasing means.
