Embodiment Construction

[0035] The same numerical reference numerals are used in the drawings to designate the same or similar constituent parts.

[0036] figure 1 A preferred embodiment of the writing instrument according to the invention is shown. The tool 1 has a barrel 2 extending along a central axis Z from a front end 2a to a rear end 2b. The front end 2a has a front hole 3 through which a writing head 4 can be passed in the image 3 shown in the extended position and Figure 4 Move between the retracted positions shown. The rear end 2b of the barrel has a rear hole 5 through which a rear click button 6 protrudes.

[0037] The barrel 2 comprises from the front end to the rear end a nose cone 8 , a middle tubular element 9 and a rear tubular element 10 with a clip 11 . However, the cartridge may consist of a different number of parts.

[0038] The writing head 4 is formed as figure 2 The spherical head at the front end of the ink cartridge 14 is visible. The ink cartridge 14 has two opp...

Abstract

A writing instrument comprising: a barrel (2) extending along a central axis (Z) between a front and a rear ends (2a, 2b) provided with apertures (3, 5) ; a writing tip (4) movable between an extended position and a retracted position; an actuating mechanism (20) comprising a plurality of parts for extending and retracting the writing tip upon actuation of an actuation member (6) ; and a cushioning device (30) enabling a retraction of the writing tip when an excessive pressure is exerted thereon by an user. The cushioning device comprises a spring member (32) elastically deformable in the central axis direction, which is integrally formed with a movable part (23) of the actuating mechanism. The part (23) is movable relative to the barrel (2) along said central axis. The spring member has a free end (32b) abutting the barrel and has a through hole (35) extending along said central axis. A stem (22b) connects the actuating member to the actuating mechanism.

Description

technical field [0001] The present invention relates to writing instruments having retractable writing tips and cushioning means for retracting the writing tips when excessive pressure is applied to the writing tips by the user. More specifically, the present invention relates to a writing instrument comprising: [0002] a tube extending along the central axis between the front end and the rear end respectively provided with the front hole and the rear hole; [0003] a writing tip movable through the front aperture between an extended position and a retracted position in which the writing tip is within the barrel; [0004] a drive mechanism comprising a plurality of components for extending and retracting the writing head upon actuation of the drive element; and [0005] Buffer. Background technique [0006] The use of a cushioning device increases the user's writing comfort and prevents damage to the paper or to the writing head. It can be used for various writing imple...
