US 7001090 B2Abstract
A offset pen includes a holding part, a writing end and a connecting part connected therebetween, in which the writing end and the holding part are disposed on different axes. When the user is operating the writing tool, the holding part inclines naturally while the writing end keeps vertical to the writing surface, and the writing result can be observed through the visible space formed between the writing end and the holding part. A holding end is disposed at the front end of the holding part of the writing tool, and each surface of the holding end can be twisted into irregular surfaces. Since the holding part, the connecting part and the writing end are substantially arranged as a Z letter, a perfect fitting feeling of the fingers can be created. Therefore, different users can feel comfortable and the fingers of the users with different holding poses can be naturally directed to a correct holding position, so as to form various geometric states suitable for hand holding. In addition, the holding part includes a receiving space for receiving the refills for substituting.
The present invention relates to an improved structure of a different axial pen, and particularly to a writing tool which is improved from the “OFFSET PEN” of U.S. Pat. No. 6,250,818 and can overcome the disadvantage of the difficulty of seeing the writing position. The writing tool has a holding part structure, which lets the user have a holding pose for naturally positioning and keep a good writing habit to ensure smooth writing and neat written characters. The writing tool can also increase the comfort of the fingers operating the different axial pen, and is more easily operated.
For a long time, all the common writing tool, such as a pencil, a colored pencil, a pen, a rollerball pen or a writing brush, belongs to a linear design, i.e. the writing end and the holding part are designed on the same axis. Due to the structure limit of the human hand, the holding part would be inclined rearward, which results in an inclined angle between the writing end and the working surface. Also, the writing surface would be sheltered by the hand and the writing end of the writing tool, so that the writer cannot clearly monitor the writing contents in time or control the precision.
To overcome the above-mentioned problems, the Inventor provides a solution for the “OFFSET PEN” of U.S. Pat. No. 6,250,818, i.e. changing the connecting manner of the writing tool, so that the holding part and the writing end are arranged at different axes. As a result, the user can maintain the original writing pose, but the writing view would not be sheltered, so as to keep stable writing works and reduce the loading of the writer.
It is an object of the present invention to provide a offset pen, in which the writing end and the holding part of the writing tool are not arranged at the same axis, but substantially arranged as a Z letter. The holding end has a positioning effect, which lets the user get a concerted holding action and develop a natural and correct writing habit.
Please refer to FIGS. 1 and 1A. The offset pen provided by the present invention mainly includes a holding part 1 and a writing end 2 disposed on the front end of the holding part 1, so that the writing end 2 and the holding part 1 are disposed on different axes. The offset pen further includes a connecting part 3 connected between the holding part 1 and the writing end 2, and the holding part 1, the writing end 2 and the connecting part 3 are substantially arranged as a Z letter. A holding end 11 is disposed on the front end of the holding part 1 close to the connecting part 3. The cross-section of the holding end 11 is a triangle, which is suitable to be held for the user. Therefore, when the user operates the offset pen of the present invention, his hand would be directed to a correct position on the holding end 11, so as to avoid improper holding pose, ensure holding on the correct position each time, and develop a good holding habit.
Please refer to FIGS. 8˜10. For conforming to the mold design, the writing end 2, the holding part 1 and the connecting part 3 can be manufactured independently. The rear end of the writing end 2 includes a positioning slot 25, and the connecting part 3 includes a positioning plug 26 correspondingly, so that the positioning slot 25 and the positioning plug 26 can fix with each other by directly fitting or other prior technique.
Please refer to FIGS. 11˜13. A rotating axis 27 is disposed between the writing end 2 and the connecting part 3, so that the writing end 2 can be rotated at a different axial angle with respect to the connecting part 3 and adjusted according to the writing pose or habit of the user to achieve the best operating effect.
