TWI283641B - Retractile mechanism for refills of writing instrument - Google Patents

Abstract

A retractile mechanism for refills of writing instrument includes an outer tube, an inner tube, a refill and a compression spring, wherein the refill is engaged within the inner tube so as to slide in the inner tube simultaneously. The inner tube has a ring slide with load and an outer ring flange for blocking purpose. The outer tube is provided with a button hole at an appropriate location. The button hole is provided at its outside with an elastic button, such that the elastic button is able to pass through the button hole and to elastically urge against the inner tube. When swinging the writing instrument forwards, the inner tube and refill are able to slide forwards by means of inertia of the ring slide. When the outer ring flange of the inner tube surpasses the button hole, the elastic button is able to elastically urge against the outer ring flange of the inner tube from an outside of the button hole, to project the tip of the refill outwards in place thereby assuming a writing position. When pulling the elastic button to disengage from the outer ring flange, the compression spring provided to the front end of the refill would retract the inner tube and refill backwards to assume a storage position, whereby allowing easy operation of retraction of the refill.

The object of the present invention is to provide a refill structure of a pen reel which is sleeved into an inner sleeve and can be slid back and forth with the inner sleeve in the outer barrel, and a front end of the inner sleeve is provided with a It has a load ring and a stop ring for the outer ring; and a buttonhole is provided on the outer pipe, and the second elastic body is used to penetrate the button hole and elastically press the inner sleeve. When the front end of the writing instrument is tilted forward, the inner sleeve can slide forward by the load ring of the front end, and when the outer ring flange of the inner sleeve slides forward and passes over the button hole of the outer pen tube, the elasticity The button can be elastically forced by the outside of the buttonhole and the card is stuck on the outer ring flange.

1283641 Description of the invention: The inner sleeve and the forwardly protruding pen tip cannot be retracted backward to form a writing state; and when the elastic button is pulled outward and away from the outer ring flange, the refill and the inner sleeve can be The compression spring at the front end of the refill is retracted backward to form a stowed state, so as to achieve the purpose of easy operation of the telescopic retraction. A further object of the present invention is to provide a refill structure of a pen refill structure in which an inner end of the outer pen tube is provided with a guiding groove, and a circular path width of the guiding groove is slightly larger than a circular diameter at the rear end of the inner sleeve The width allows the rear end of the inner sleeve to extend into the guide groove to slide back and forth, thereby increasing the stability of the inner sleeve sliding in the outer pen tube. 9 Relatively increasing the stability of the refill to avoid shaking when writing.

Another object of the present invention is to provide a refill structure of a writing instrument, wherein the elastic button can be disposed on the inner surface of the tail end of the pen holder, and the elastic clamping force of the pen holder is used as the elastic button to force the elastic force. The elastic button can be inserted through the outside of the buttonhole and elastically pressed on the inner sleeve, especially when the user pulls the pen holder to be stored in the clip pocket, the elastic button can be pulled simultaneously to make the inner sleeve and the inner sleeve and The structure of the present invention and its technical features are described in detail below with reference to the following illustrations, in order to make the invention more conspicuous and detailed by inadvertently retracting the refill without retracting the refill: Referring to Figures 1, 2, 3, 4, and 5, the "refill structure of the pen refill" of the present invention includes an outer pen tube 1 一笔, a core 2 〇, an inner sleeve 30, and a compression. The spring 40, wherein the outer pen tube 1〇 can be composed of the pen body 11, the pen tip 12, the pen tail 13 and the pen holder 14, and the pen tail 13 can be internally provided with a coaxial and appropriate depth cylindrical guiding groove 131; 20 rear end sleeves nested in the inner sleeve 30

Page 6 1283641

Internally, the refill 20 and the inner sleeve 30 can be synchronously slid back and forth in the outer pen tube 1 ;; and the inner sleeve 30 is a tube body whose front end is closed at the rear end, and a load ring is arranged on the front end thereof. 32 and a stop outer ring flange 31; and the button body 11 of the outer pen tube 10 is provided with a button hole 1 Π, and the outer edge of the button hole lu is provided with an elastic button 141, so that the elastic button 141 can be worn through The button hole ^1 is inserted and elastically pressed on the inner sleeve 30. , 5, invention description (3) and in the continuous manufacturing 'the elastic button 141 can be set at the end of the pen holder n, and by the elastic clamping force of the pen holder 14 as the elastic force of the elastic button 1 4 1 The elastic button 141 has sufficient pressing force to elastically press the button sleeve ln to elastically press the inner sleeve 30; and when the user pulls the pen holder 14 to clamp the pen holder into/out of the pocket When the elastic button 141 is moved out synchronously, the inner sleeve 3〇 and the refill 20 are also retracted backwards synchronously, so as to ensure that the refill tip 21 is retracted during storage to avoid staining the clothes. . Further, the inner end of the outer pen tube 1 ' is the inside of the pen tail 13 , and a guiding groove 131 of a proper depth can be provided, and the circular path width of the guiding groove 131 is slightly larger than the circular diameter of the rear end of the sleeve 30 . The width of the inner sleeve 3 can be extended into the guiding groove 131 to slide back and forth, so that the inner sleeve 30 can be stably moved back and forth in the outer pen tube 1 ,, and the stability of the refill 20 can be relatively increased to avoid The refill 2〇 is shaken when checking b. The setting position of the button hole 1 1 1 of the outer and outer pen tube 10 is designed to match the outer ring flange 31 of the inner sleeve 3 &, as shown in Fig. 5, when the elastic button is 4 J passes through the sister hole 111 and elastically presses on the inner sleeve 30 and blocks the outer ring flange 31, and the refill tip 21 of the refill 20 that fits inside the inner sleeve 30 can protrude from the pen tip 1 2 outside the exit, and form a writing state. ,

On page 7 of 1283641, a compression spring 4 is disposed in the pen tip 12, and the compression spring 4 is sleeved on the front portion of the refill 20, so that the refill 20 is elastically supported by the g12 and the inner sleeve 30 by the compression spring 4〇. Between the X inner sleeve 3 〇 is provided with a load ring block and a retaining outer ring flange 31, which can be made of copper or ferrous metal, respectively, and the refilling of the refill of the present invention is separately illustrated. Operation Condition (I) As shown in Figs. 2 and 5, when the pen tip 21 is to be extended, the user can hold the pen tube 10 to move the pen tip 12 forward to cause the pen to drive the refill 2. ...note 12 direction) inertial sliding, then = J; 33 〇 ° j outer ring flange 31 forward over the outer pen tube 1 〇 buttonhole ln, the elastic button 14; can be externally through the buttonhole ln and elastic Pressing and blocking the outer ring convex, 'so that the inner sleeve 30 and the refilled tip 21 that has been extended forward cannot be retracted backwards' to form a writing state. ^二:), and as shown in Figures 1 and 4, when the refill tip 21 is to be retracted, the user = ^ clip 14 to cause the elastic 丨 to leave the buttonhole (1) and the outer ring flange 31, And 2 ί tube 3 ◦ can be retracted by the compression spring 40 with the refill 2 in the front section, and then retracted backwards to form a stowed state. ^The inner sleeve 30 can be made of copper or iron
