  • Patent number: 8087841
    Abstract: A retractable pen includes an improved triggering device (i.e., an actuating means), which is easy for manufacturing and user-friendly. The retractable pen has a pen-body having two pen-tubes, a pen-cartridge within the pen-body, and an actuating means. The actuating means not only triggers the movement of pen-cartridge (slidable protrusion/retraction of the pen-cartridge) but also, at the meantime, triggers length-change of pen-body (slidable movement between the two pen-tubes).

  • Publication number: 20110103877
    Abstract: A pen with rotating ornaments is disclosed. The pen includes a pen tube with a power supply therein, a motor whose one end is arranged with a wire connected with the power supply while at least an end is disposed with a shaft that connects with an ornament. The ornament is arranged with figures, words or advertisement. By the voltage from the power supply, the motor rotates so that the shaft rotates and drives the ornament to rotate. Thus by the rotated ornament through transparent pen tube, the interest senses, decorative effects and advertising effect of the pens are improved.

  • Patent number: 7926968
    Abstract: A dual mode luminous ball pen is disclosed. The luminous pen includes a pen shaft; a tapered transparent tip portion disposed on a proximal end of the shaft; a refill, a switch portion, a lamp, a control portion, and a button. The switch portion disposed inside the pen shaft and connected to the tip portion for rotating a sleeve. The lamp includes at least a cell, a first light emitting diode (LED), and a second LED, and can be rotated together by the sleeve to supply/cut-off a power supplied by the cell to the LEDs. The control portion is disposed on the switch portion to turn on one of the first and second LEDs. The button is depressed into the pen shaft to rotate the control portion.

  • Publication number: 20100322696
    Abstract: A pen with windows for display of patterns at random is revealed. The pen consists of a pen holder, at least one window disposed on the pen holder, a first control part and a second control part operated outside the pen holder. At least one rotating part with a plurality of patterns, a driving member and a stopping member are respectively mounted in the pen holder. The first control part is operated for driving the rotating part to rotate by the driving member. Then operate the second control part so as to stop the rotating part by the stopping member and one of the patterns is displayed through the window.

  • Patent number: 7854559
    Abstract: A pen with double pen barrels is revealed. The pen with double pen barrels includes two pen barrels connected in parallel, a pen refill in each pen barrel, and a driving member disposed between the two pen barrels. When one of the pen barrels is pressed and moved downward, a pen refill extends out of a front end of the pen barrel, located to be in writing state. Then by releasing a stopper of the pen barrel, the pen barrel moves upward and the pen refill retracts to be in storage state. Thus the pen barrel and the pen refill extends and contracts synchronously. Moreover, interests in use of the pen are increased.

  • Publication number: 20090016801
    Abstract: A handy tool pen is mainly constituted, for example, to write a brief summary and to implement a repair of hardware equipment. A hollow shaft 20 has a working end at a proximal end, where a hole axially formed through a center. A handwriting instrument of the refills is thereby stretched out from the working end, or retracted in the working end. When the handwriting instrument stretched out from the hole can write well, while the handwriting instrument retracted in the working end, which can implement a repair for hardware equipment. As well known, a spring fit around a circular cylindrical surface of the refills can urge the refills descend downward to stretch out the handwriting instrument to write, and also can urge the refills elevate upward to retract in the working end, which use for repairing office equipment or even hardware.
