| 20120020719 | ROTARY-TYPE RETRACTABLE WRITING IMPLEMENT WITH AN ANTI-DRYING DEVICE - The present invention relates to a rotary-type retractable writing implement with an anti-drying device, wherein an upper shaft and a lower shaft are coupled together such that the two shafts are rotatable in opposite directions, and a cartridge accommodated in a intermediate connection member is movable, and an open/shut module for covering a nib opens/shuts by means of the movement of the cartridge so as to provide a nib-advancing path. The rotary-type retractable writing implement with an anti-drying device comprises: said cartridge equipped with a writing nib; said intermediate connection member having a slit for the upward and downward sliding of the cartridge accommodated therein; said lower shaft which is coupled to the intermediate connection member, and which has a nib hole for extending/retracting the nib therethrough; said upper shaft having a thread which enables the cartridge accommodated in the intermediate connection member to move in accordance with the integrated rotation of the intermediate connection member and the lower shaft; and a is ball shutter disposed within the lower shaft to open the nib-advancing path when the nib advances by the upward and downward sliding of the cartridge, and to shut the nib-advancing path when the nib moves backwards and to permit the nib to be accommodated in the closed space. | 01-26-2012 |
| 20120014737 | WRITING IMPLEMENT WITH SIMULTANEOUS RETRACTABLE ENDS - The present invention relates to a writing implement, both ends of which are retractable, in which an upper shaft and a lower shaft are coupled together such that the two shafts are rotatable relative to each other, and thus a cartridge and an eraser holder accommodated in an intermediate connection member are simultaneously movable in the upward and downward directions. The writing implement of the present invention comprises: said cartridge equipped with a writing nib; said intermediate connection member having a slit for upward and downward sliding of the cartridge accommodated therein; said lower shaft coupled to the intermediate connection member, and which has a nib hole for extending/retracting the nib therethrough; said upper shaft having a thread which enables the cartridge accommodated in the intermediate connection member to move in accordance with the integrated rotation of the intermediate connection member and the lower shaft; a cam coupled to one end of the upper shaft, and which has an inner wall with a protrusion; an eraser holder accommodated in the intermediate connection member such that the eraser holder engages the protrusion of the cam and the slit of the intermediate connection member and rotates in the upward and downward directions in accordance with the integrated rotation of the intermediate connection member and the lower shaft; and a ball shutter accommodated in the lower shaft to open/shut the nib hole by means of the upward and downward sliding of the cartridge. | 01-19-2012 |
| 20110318083 | WRITING IMPLEMENT WITH A RETRACTABLE CLIP - The present invention relates to a writing implement with a retractable clip in which a clip is configured to be retractable into a pen body, so that the clip can be kept in a retracted state when the clip is not being used and, therefore, the clip is not easily broken and does not easily injure a user and, furthermore, allows the user to efficiently use a space for receiving writing implements. | 12-29-2011 |
