Foldable writing implement

Abstract

A ball point pen has a elongate shank 10 that supports a ball point element inside. A handle 11 can pivot and fold over and be held closed against the shank 10. This allows the pen to be maintained in a folded-up configuration and easily carried in a breast pocket or purse. The pen is biassed towards a writing configuration with the shank and handle connected end-to-end.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to writing implements.

2. Description of Prior Art

Writing implements are presently provided for writing use and for carrying in a breast pocket. As such, it is normally a requirement that the nib, a ball or pencil point is covered for carrying. A separate over may be easily misplaced or lost. In some cases, the nib or pencil point, say, is retracted so as not to be exposed when not is use and so as not to soil the fabric of the pocket when inserted into and removed from the pocket, and no separate cover is required. A writing implement may be itself relatively short, but never-the-less each writing instrument must be sufficiently long for normal use and preferably ‘balanced’ so that as to be comfortable for writing. This means that a normal writing implement is relatively long and does not fit easily into a shallow breast pocket that may be present on a shirt, or fit comfortably into a short purse or wallet.

SUMMARY OF THE INVENTION

It is an object of the invention to overcome or at least reduce these problems.

According to the invention there is provided a writing implement having a writing head supported by an elongate shank and an elongate handle that fits end-to-end to the shank in a writing configuration for normal use, in which the handle is pivotable connected to the shank and folds over the shank and is held against the shank the implement is in a folded configuration.

The pivotable connection is preferably spring biassed to restrain the shank and handle towards the writing configuration.

A remote end of the handle may manually releasably lock to a remote end of the shank to hold the writing implement in the folded position.

The handle preferably extends over an end of the shank and the writing head in the folded configuration.

A pocket clip may be mounted to and extending along a side of the handle.

BRIEF DESCRIPTION OF THE DRAWINGS

A ball-point pen according to the invention will now be described by way of example with reference to the accompanying drawings in which:

FIG. 1 is an isometric view of the pen in a writing configuration;

FIG. 2 is a isometric view of the pen in a folded configuration;

FIG. 3 is an isometric view of the pen in an intermediate configuration;

FIG. 4 is an isometric exploded view of the pen;

FIG. 5 is a sectional view of the pen in the folded configuration; and

FIG. 6 is another sectional view of the pen in the folded configuration.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, in FIGS. 1 to 3, the pen has an elongate shank 10 and an elongate handle 11. The shank and handle are pivotably connected together by a pin 12. A pocket clip 13 is mounted to the handle 11. The handle and shank fit together end-to-end in FIG. 1 and in FIG. 2 the handle surrounds the shank 10 in the folded configuration.

In FIG. 4, the shank 10 supports a replaceable ball point element 14 and a shroud 15, that push-fits into the shank 10, covers part of the element 14 and supports a writing head 16 as required. The pivot pin 12 is provided with a biassing spring 17 that biasses the pen towards the writing configuration. The handle 11 has a pivotably manually releasable button 18 that is releasable to allow the spring 17 to open the pen from its folded configuration.

In FIGS. 5 and 6, the various componenents of the pen are shown and it will be apparent how the pen is retained in and released from its folded configuration. It can also be seen that the shank 10 has an integrally formed abutment 19 that will bear against a stop 20 integrally formed on the handle. The abutment 19 will be urged by the spring 17 against the stop 20 when the pen is in a fully open configuration for writing.

The described pen can therefore be folded, and held folded, to fit comfortably in a wallet or shallow pocket, for example. For use, the button 18 is depressed to allow the pen to open and provide a pen of ‘comfortable’ length for writing. The writing head 16, and indeed the element 14, is well-protected and covered over by the handle 11 when the pen is in the folded configuration. The handle is permanently attached to the shank and so cannot be lost or independently misplaced.

Claims

1. A writing implement having a writing head supported by an elongate shank, the shank having a shank remote end opposite a shank connector end, and an elongate handle, the handle having a handle connector end opposite a handle remote end, said handle connector and shank connector ends fit end-to-end in a writing configuration for normal use, wherein the handle is pivotably connected to the shank and folds over the shank and is held against the shank when the implement is in a folded configuration and said handle has a cooperative engaging locking means at the handle remote end for releasable engagement and locking retention of the handle to the shank at the shank remote end when the handle is folded over the shank wherein actuation of said engaging locking means releases said shank to automatically pivot from said folded configuration to said writing configuration.

2. A writing implement according to claim 1, in which the handle is pivotably connected to the shank by a pivotable connection which is spring biased to restrain the shank and handle towards the writing configuration.

3. A writing implement according to claim 1, in which the handle extends over an end of the shank and the writing head in the folded configuration.
