Definitions

  • the present invention relates to a writing instrument. More particularly, the present invention relates to an improved pen such as a ball-point pen and an improved mechanism for activating and/or deactivating the pen.
  • pens comprise an outer casing containing a pen refill and a removal cap attached to the lower portion of the pen to cover the pen nib.
  • Others are the commonly known push button and twist type pen. In the first category of pen mentioned, the cap is easily lost, is small and is awkward to use.
  • pens of the second type push button
  • push button When pens of the second type (push button) are carried in a pocket its button may be unintentionally pushed to activate the pen. This may result in staining of the pocket with ink.
  • Pens of the third type have attempted to alleviate these problems, however, the pen nib is again often exposed unintentionally. The user will commonly only partially close the pen leaving part of the nib exposed. An added problem with the twist pen is that they typically cannot withstand sustained pressure on the pen nib without retracting into the lower portion of the pen.
  • telescopic pen There is a final type of telescopic pen that has tried to alleviate the above problems. However, these pens have complex and relatively expensive mechanisms involving materials such as magnets which also tend to impact on their durability.
  • these pens prevent unintentional activation of the pen, they do not adequately prevent unintentional deactivation as the upper portion of the pen can easily and unintentionally be pushed down having the effect of retracting the pen nib into the lower portion of the pen.
  • the design of each of these pens prevents a sleek and smooth outer appearance.
  • a writing instrument comprising: a main body comprising an upper portion and a lower portion; a pen refill comprising a pen nib located within the upper and lower portions; wherein the upper portion of the pen is capable of being pulled back whereupon on releasing the upper portion, the upper portion returns to its resting position and the pen nib of the pen is exposed.
  • a writing instrument comprising: a main body comprising an upper portion and a lower portion; a pen refill including a pen nib located within the upper and lower portions; a rod interconnecting said upper and lower portions wherein the upper portion is capable of moving along the rod; a first spring located at a first end of the rod; a second spring located at a second end of the rod; a collar located on the rod and situated between the first and second springs; wherein the upper portion of the pen is capable of being pulled back and compressing the first and second springs whereupon on releasing the upper portion the pen nib of the pen is capable of being exposed.
  • the present invention therefore relates to a new operating mechanism for actuating a pen such as a ball-point pen.
  • the upper and lower portions may be substantially cylindrical and may be shaped and/or adapted to be easily held by a user.
  • the upper and lower portions may be substantially hollow in form and may form an outer casing for the pen.
  • a mechanism for operating the pen may be located within the upper and lower portions.
  • the pen may have an inactivated state where the pen refill is fully located within the upper and lower portions of the pen.
  • the pen may also have an activated state wherein the pen refill may be extended from within the upper and lower portions of the pen and the pen nib therefore being exposed from the lower portion ready to be used for writing by a user.
  • the pen may be activated and inactivated as many times as necessary (e.g. a plurality of times) by the operating mechanism of the pen.
  • the rod may be a push rod and may allow the upper portion to be pulled back from its resting position and away from the lower portion. During this process the rod may be exposed. On release of the upper portion, the upper portion may spring back towards the lower portion and ultimately to its resting position against the lower portion and the pen nib may become exposed.
  • the rod may extend from and be connected to the lower portion.
  • the spring may be mounted between an upper engagement means such as an annular rim and a lower engagement means such as a further annular rim which may be formed by a bottom face of the upper portion.
  • the rod may comprise a main tubular body and elongate apertures (e.g. two, or two or more) at one end of the rod.
  • the rod may also comprise, for example a further four apertures which may, for example, during use, engage with catch members of the collar. In particular embodiments there may be two catch members.
  • a collar situated around the rod.
  • the collar may be akin to a block which may extend around the rod.
  • the cap may be located at the top of the rod and may abut and/or engage against a top end of the upper portion of the pen.
  • the writing instrument may comprise a further annular rim which may extend around the rod and may be located in the region between the two springs.
  • This further annular rim may be used as a stop against the collar during the activation/deactivation of the pen.
  • the upper portion of the pen may be pulled back which may have the effect of compressing the first spring between the upper annular rim and the lower annular rim.
  • the second centrally mounted spring may become compressed between the cap and the collar.
  • the pen may therefore contain stored energy to activate the pen.
  • the collar may be unlocked from the rod.
  • the upper portion On release of the upper portion, the upper portion may spring back to its resting position and, at the same time, as the second spring decompresses it may push the collar down the rod until it rests on the further annular rim. At this point the collar may again lock onto the rod.
  • This action may activate the pen by pushing the pen refill down the interior of the main body of the pen and out of the lower portion of the pen. At this point the pen may be described as activated as the pen nib may become exposed.
  • the upper portion of the pen may be pulled back which may have the effect of compressing the first spring between the upper annular rim and the lower annular rim.
  • the second centrally mounted spring may become compressed between the cap and the collar.
  • the collar may be pulled up the rod by the further annular rim.
  • the collar may at a specific point lock onto the rod.
  • the upper portion may spring back to its resting position. This action may deactivate the pen by pulling the pen refill up the interior of the main body of the pen and into the lower portion of the pen. At this point the pen may be described as deactivated as the pen nib may no longer be exposed.
  • a method for activating and/or deactivating a writing instrument comprising: providing a main body comprising an upper portion and a lower portion; providing a pen refill including a pen nib located within the upper and lower portions; providing a rod interconnecting said upper and lower portions wherein the upper portion is capable of moving along the rod; providing a first spring located at a first end of the rod; providing a second spring located at a second end of the rod; providing a collar located on the rod and situated between the first and second springs; wherein the upper portion of the pen is capable of being pulled back and compressing the first and second springs whereupon on releasing the upper portion the pen nib of the pen is capable of being exposed.
