A multi-function writing instrument includes a front section having a writing point opening and a rear section having an eraser opening. The rear section and the front section are rotatably connected to each other. A plurality of marking tips are disposed in the front section. One of the marking tips is a pencil lead marking tip. The marking tips are alternately selectable for extension through the writing point opening. An eraser holder is movably disposed in the rear section. An eraser is mounted in the eraser holder. The eraser holder is selectable for extension through the eraser opening. A means for simultaneously propelling the pencil lead marking tip through the writing point opening and the eraser through the eraser opening upon rotation of the front section relative to the rear section is housed in the multi-function writing instrument.

A retractable clip assembly (26) has a cap (4) with a recess, a fulcrum within the cap, a clip arm mounted for movement in the recess (23), and a spring that lies between the cap and the clip arm. The clip arm (6) is permanently affixed to the spring. The clip arm has a retracted position, an intermediate position, and an extended position. In the retracted position, the clip arm resides in a continuous plane with the cap profile. In the intermediate position, the front tip of the clip arm is tilted up and out of the recess via the spring pivoting against the fulcrum (11). In the extended position, the back end of the clip arm extends out by feeding material into the space under the clip arm.

An expandable pen has a pen barrel (50) with an expanding middle section. The pen barrel holds a retractable ball point pen refill cartridge (65). When the pen is expanded, the writing tip (60) of the refill is extended from a retracted position inside the pen barrel to a writing position, while the barrel becomes full length for comfort when writing. The pen may be collapsed for storage, which simultaneously retracts the writing tip inside the pen barrel.

An interactive data transfer system and method is provided. In embodiments of the invention, the data transfer system includes a computing device, and a data well for interfacing with an elongate instrument, the elongate instrument having a data transfer end with a data transfer tip. The data well has a housing with an opening for receiving the data transfer tip of the elongate instrument. The data well also has a communications port operatively coupled to the computing device to provide data to the computing device, and the data well has a data communication device contained in the housing for interfacing with the data transfer tip when the data transfer end of the elongate instrument is received in the opening. The computing device is programmed to receive data from the data well. The received data includes data indicative of at least one address on a global communications network. The computer device is also programmed, upon receipt of the at least one address, to launch an application to retrieve information related to the at least one address from the global communications network and transmit such information to the computing device.
摘要:
An expandable writing instrument has a writing end body section and a rear body section mounted to the writing end body section for relative axial and non-rotational movement between an extended position with the rear body section spaced away from the writing end body section, and a retracted position with the rear body section closer to the writing end body section. A spring in the writing end body section biases the cartridge upwardly. A helix cylinder is mounted for rotation and axial movement in the rear body section with a peg of the rear body section sliding in a track of the helix cylinder. The track is a closed loop with left and right hand helixes so that axial movement of the rear body section causes rotation of the helix cylinder continuously in one rotational direction. A shuttle receives a cartridge body and is mounted for axial movement in the helix cylinder. A shuttle cam on the shuttle is mounted for axial non- rotational movement to the writing end body section. Shuttle cam surfaces slidably engage cam surfaces of the helix cylinder and the cam surfaces include a high point that engages a flat portion of another cam surface for moving the shuttle with rotation of the helix cylinder, to project a writing tip of a cartridge out of the bottom opening in the extended position.

A data well (10) arrangement is for storing data and for interfacing with a writing implement (20) having a writing end (22) with a writing tip (24) and data transfer end (30) with a data transfer tip. The data well arrangement has a housing (12) with an inlet opening for receiving an end of the implement. A data reader (16) is in the housing for facing the data transfer tip to exchange data with the implement when the data transfer end of the implement is received in the opening. A shutter (50) in the housing is engageable with an engagement portion of the implement for moving of shutter between a writing end storage position in which the data reader is inaccessible, and an interface position in which the data reader is accessible to the data transfer tip with the shutter being engaged by the engagement portion of the implement, only when the data transfer end is received in this opening.

A hand instrument (10) with variable grip arrangement has an instrument body of the type to be held between the fingers of the hand for use, the body having an active end (14) and an opposite end (16). A resilient material forms a grip (18) around the body near the active end. Radial expansion beams (20) are under the grip for bending radially outwardly for expanding the grip into an expanded ergonomic position and for resiliently returning to a straightened condition for contracting the grip into a contracted storage position. Cams or threads or other mechanisms engage the beams for moving them between the expanded and the contracted positions with rotation of a part of the instrument body.
