Detailed Description

The following describes in further detail specific embodiments of the present invention based on the drawings. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.

Referring to fig. 1 to 3, the present invention provides an ergonomic propelling pencil, which includes a cap 10, a tip 20 disposed at the bottom of the cap 10, a refill unit disposed in the cap 10, a cap 30 disposed at the top of the refill unit and protruding from the top of the cap 10, and a clip 40 disposed at the outside of the top of the cap 10.

The part of the pen cap 10 close to the pen point 20 is a holding part 11.

Referring to fig. 4, the circumferential side of the cap 10 or the grip 11 includes three main sides and three transition sides 15. In one embodiment, three main sides and three transition sides 15 are disposed on the whole circumferential side of the pen cap 10, and in this case, the circumferential side of the grip 11 is necessarily also provided with three main sides and three transition sides 15; in another embodiment, three main sides and three transition sides 15 are provided only on the circumferential side of the grip 11, the main sides and the transition sides 15 are not provided on the upper portion of the pen cap 10, and the upper portion of the pen cap 10 may be formed in a cylindrical shape.

The first included angle between any two adjacent main side surfaces is 120 degrees. The transition side surface 15 is a curved surface or a cambered surface connecting two adjacent main side surfaces. Smooth transition is realized to transition side 15, avoids forming comparatively sharp edges and corners to be convenient for the user to hold.

In the present embodiment, the three main side surfaces are the first main side surface 12, the second main side surface 13, and the third main side surface 14, respectively.

A plurality of concave thumb abutting parts 121 are obliquely arranged on the first main side surface 12 of the holding part 11 at intervals, and the shape of the thumb abutting part 121 is an ellipse.

The second major side 13 of the grip 11 is provided with a plurality of concave index finger contacting portions 131 at intervals and obliquely, and the shape of the index finger contacting portion 131 is oval.

A second included angle a between the long axes of the thumb abutment 121 and the index finger abutment 131 and the central axis of the cap 10 is 10-30 degrees, preferably 25 degrees.

The third main side surface 14 of the grip 11 is provided with a plurality of concave middle finger contact portions 141 at intervals, the shape of the middle finger contact portion 141 is an ellipse, and the long axis of the middle finger contact portion 141 is parallel to the central axis of the pen cap 10.

The thumb contact portion 121, the index contact portion 131, and the middle contact portion 141 are provided at different heights with respect to the nib 20.

In use, a person's thumb is positioned in the thumb abutment 121, the index finger is positioned in the index abutment 131 at a lower height than the thumb abutment 121, and the middle finger is positioned in the middle abutment 141 at a lower height than the index abutment 131. Since the long axis of the middle finger abutting portion 141 is parallel to the central axis of the cap 10, the middle finger can be relatively comfortably abutted against the middle finger abutting portion 141; because the thumb abutting part 121 and the forefinger abutting part 131 are obliquely arranged and are matched with the shapes of the thumb and the forefinger when a person holds the pencil, the thumb and the forefinger can be conveniently and comfortably abutted against the pencil cap 10 and can be caught from two directions. Thus, the multifunctional pen accords with the human engineering, improves the use comfort level, and is convenient for a user to hold and write.

The thumb contact portion 121, the index finger contact portion 131, and the middle finger contact portion 141 simultaneously position the finger on the pen cap 10 and prevent the finger from sliding with respect to the pen cap 10.

In the present embodiment, the top end of the clip 40 is disposed on the transition side 15 between the first main side 12 and the second main side 13, that is, the first main side 12 and the second main side 13 are respectively located at two sides of the clip 40.

Compared with the prior art, the ergonomic propelling pencil of the utility model comprises a pencil cap 10, a pencil head 20 arranged at the bottom of the pencil cap 10, a pencil lead unit arranged in the pencil cap 10, and a pencil cap 30 arranged at the top of the pencil lead unit and protruding out of the top of the pencil cap 10; the part of the pen cap 10 close to the pen point 20 is a holding part 11; the circumferential side surfaces of the holding part 11 comprise a first main side surface 12, a second main side surface 13, a third main side surface 14 and three transition side surfaces 15, wherein the transition side surfaces 15 are curved surfaces which are connected between the first main side surface 12 and the second main side surface 13, between the second main side surface 13 and the third main side surface 14 and between the third main side surface 14 and the first main side surface 12; a plurality of concave thumb abutting parts 121 are arranged on the first main side surface 12 at intervals and in an inclined manner; a plurality of concave index finger abutting parts 131 are arranged on the second main side surface 13 at intervals and in an inclined manner; the thumb abutting part 121 and the index finger abutting part 131 are both elliptical in shape; a plurality of concave middle finger abutting parts 141 are arranged on the third main side surface 14 at intervals, the shape of the middle finger abutting parts 141 is oval, and the long axis of the middle finger abutting parts 141 is parallel to the central axis of the pen cap 10; the thumb contact portion 121, the index contact portion 131, and the middle contact portion 141 are provided at different heights with respect to the nib 20. Therefore, the pen cap is convenient for fingers to be positioned on the pen cap, prevents the fingers from sliding relative to the pen cap, accords with human engineering, improves the use comfort level, and is convenient for a user to hold and write.
