Embodiment Construction

[0038] Referring now to the drawings, in which like reference numerals are used to refer to like or similar elements, figure 1 , figure 2 and image 3 A view of a multifunctional writing instrument 100 with a push mechanism 1 is shown. Such as figure 1 The multifunctional writing implement shown in has a rear section 10 (eg, upper tube, cap) and a front section 20 (eg, lower tube). Such as figure 2 The assembled pushing mechanism 1 shown in FIG. 1 pushes the pencil point 2 through the writing point opening 27 in the lower tube 20 while pushing the eraser 43 through the eraser opening 11 in the upper tube 10 . The simultaneous pushing of the pencil point 2 and the eraser 43 is caused by rotating the upper tube 10 relative to the lower tube 20 .

[0039] refer to figure 2 and image 3 , the pushing mechanism 1 is accommodated in the upper tube 10 . The pushing mechanism 1 includes a guide 50 , a cam assembly 30 , a cam follower 60 and an eraser clamp 40 .

Abstract

A multi-function writing instrument includes a front section having a writing point opening and a rear section having an eraser opening. The rear section and the front section are rotatably connected to each other. A plurality of marking tips are disposed in the front section. One of the marking tips is a pencil lead marking tip. The marking tips are alternately selectable for extension through the writing point opening. An eraser holder is movably disposed in the rear section. An eraser is mounted in the eraser holder. The eraser holder is selectable for extension through the eraser opening. A means for simultaneously propelling the pencil lead marking tip through the writing point opening and the eraser through the eraser opening upon rotation of the front section relative to the rear section is housed in the multi-function writing instrument.

Description

technical field [0001] The present invention relates generally to the field of writing instruments, and more particularly to a novel and practical writing instrument equipped with a plurality of independently selectable marking tips. Background technique [0002] Multifunction writing implements provide the user with multiple writing tip options within the same writing implement, which reduces the number of writing implements to carry. [0003] Typical multifunctional writing instruments include two types: ink-based tips and pencil tips. Maximum use of the pencil point can be achieved by using an eraser that is usually affixed to the writing instrument. Since the eraser will only be used in conjunction with the tip of the pencil, the eraser is usually covered when not in use or always exposed. [0004] An example of the previous method is using a screw-on eraser cap on a multi-tool. These screw caps require an extra step in the use of the writing instrument, reducing the ...
