Patent number: 7931415Abstract: Upon depressing a knock rod in a state of writing of FIG. 8A, a cam protuberance 3b of a rotor turns rightward to assume a position shown in FIG. 8B. Upon removing a finger, the cam protuberance 3b turns sliding on a tilted surface, arrives at a position shown in FIG. 8C through a first vertical motion (distance d) and, further, arrives at a position shown in FIG. 8D through a second vertical motion (distance e). Here, a tilted surface of cam protuberance 3b comes in collision with a tilted surface of an inner cylinder cam 2b twice, and shocks are transmitted to a refill 7. By forming a step between the front half and the rear half of the tilted surface of the inner cylinder cam 2b, however, a distance of vertical motion of the cam protuberance 3b each time is shortened to decrease the shock of collision imparted to the refill each time.Type: GrantFiled: August 11, 2008Date of Patent: April 26, 2011Assignee: Mitsubishi Pencil Company, LimitedInventors: Yoshiharu Namiki, Hisami Tamano

Patent number: 7581896Abstract: The object of this invention is to provide a safety knock-type writing instrument. The writing instrument includes a barrel (10) with a cartridge (50), a gear unit (30), and a knock unit (60). The gear unit (30) is positioned on an exterior of the barrel (10) and rotatably seated on a clip (20). The knock unit (60) is provided in the barrel (10), and includes first and second protrusions (61, 62) to engage with the gear unit (30), thus operating the gear unit. In this writing instrument, when the first protrusion (61) of the knock unit disengages from the gear unit (30), the cartridge is retracted into the barrel. Thus, although a user puts the writing instrument, with the cartridge extended, in a pocket without first retracting the cartridge, the cartridge is automatically retracted into the barrel, thus preventing his/her clothing from being stained by the cartridge.Type: GrantFiled: December 31, 2004Date of Patent: September 1, 2009Assignee: Morris CorporationInventor: Hyun-son Yoon

Patent number: 4790678Abstract: A mechanism for extruding and retracting the writing member of a writing instrument which is set ready for writing by pressing a clip member vertically movable in a slit bored in the rear side wall of a cylinder, but held in a protruded state while the writing instrument is not set for writing. The clip member presses a flexible working element arranged under the clip member and having a plurality of elastic zigzag bent portions. The working element thus pressed down axially extends to press the back of the writing member contained in the front part of the cylinder and energized backward by spring action and moves the writing member forward. The tip of the writing member is protruded from the opening at the front end of the cylinder and the clip holder of the clip member is held inside the slit during writing.Type: GrantFiled: June 25, 1987Date of Patent: December 13, 1988Assignee: Pilot Ink Co., Ltd.Inventor: Toshio Araki

Patent number: 4717275Abstract: A writing instrument having a casing with an axially-extending bore seating a cantilevered arm of a pocket clip which protrudes through the casing bore when the instrument is in an "off" position. The pocket clip has guide tabs which fit into guide channels in the instrument's casing. The guide channels, with spring fingers which bias the pocket clip in the direction of the bore, are capable of releasably locking the clip in plural positions. In the "off" position the pocket clip arm protrudes through the casing aperture but the writing members housed within the casing are retracted. Moving the pocket clip to a "write" position causes a writing member to project from either the front or back of the housing and the pocket clip arm to be retracted into the casing.Type: GrantFiled: June 20, 1986Date of Patent: January 5, 1988Inventor: Dietmar Burkhardt, Jr.

Patent number: 3992115Abstract: A pen, scribe or similar instrument fits into and projects out one end of a central axial aperture in a barrel. The barrel has a longitudinal groove in its surface and angularly displaced depressions in its outer surface at the end from which the pen projects. A cap assembly has an elongated shaft axially movable and oscillatable in the longitudinal groove and held in place by an upper and lower spring around the barrel. A helical spring biases the shaft toward retracted position with an end of the shaft projecting out the end of the barrel opposite the pen. The upper end of the shaft carries a fitting having a pocket clip and a pen cap. In retracted position, the clip and cap fit into their respective depressions. By depressing the shaft end against the force of the spring the clip and cap are raised and the spiral groove and upper spring cause them to pivot with the shaft until the cap is above the tip of the pen and the clip projecting outward of the barrel.Type: GrantFiled: November 10, 1975Date of Patent: November 16, 1976Inventor: Craig F.
