Description
-~, BACKGROUND OF THE INVENTION ~ 7 The present invention relates to writing pens, and more particularly, to ball-point pens.
Pens come in a variety of shapes, sizes and types.
There are felt tip pens, ball-point pens and fountain pens, all of which employ an ink reservoir mated to a writing tip of some sort and a body or housing for containing the writing tip and reservoir. For ball-point pens, the writing tip includes a ball contained in a metallic or plastic tube to form a ball-point. In use, the ball-point is rubbed against the surface of the paper and ink flowing from the reservoir to the ball-poin-t is neatly deposi-ted on the surface of the paper.
In order to maximize the free flow of ink onto paper, the body of the pen should be held so that the ball-point is held as close to a vertical position from the surface of the paper as possible. If the ball-point is not held at such a steep angle, the ball-point lays down less ink on the paper.
Traditionally, pens have had straight tubular housings or bodies for containing the ink reservoir, which have an apertured writing end through which the writing tip projects in order to make contact wi-th the paper. The , , ;~ 73~
straight tubular nature of traditional pen bodies is adequate for retaining the writing tip and ink reservoir but does not maximize the comfortable use of the pen.
In -the past, attempts were made to improve the comfortable use o-f pens by modifying the housing with ridges or bulges located near the writing tip in order to better conform the housing of the pen to the grip of the user.
Other attempts included the use of customized or modified writing tips in order to improve the position of the writing tip in rela-tion to the grip of the user. H.R. Fehling e-t al., U.S. Patent No. 3,106,190 discloses a ball-point pen having a ball held within an angled metal tube. This angled tube permits -the ball-point to be held at the axis of the housing and at an angle closer to -the verticle when the body of the pen is held in a comfortable writing position.
Although a custom writing unit having a angled ball-point makes for better contact of ball-point with paper, the comfortable grip of the Fehling pen as with previous pens is limited by the straight stick-like shape of the body.
SUMMARY OF THE INVENTION
The present invention overcomes at least some of the limitations of the prior ar-t by providing a pen having a tubular housing with an aper-ture at one end thereof, a long ' .

tubular flexible reservoir dimensioned -to fit within the housing, a writing tip mated to the ink reservoir and dimensioned to fit through the housing aperture, wherein a lower sec-tion of the housing adjacent the apertured end is shaped to reposition the writing tip relative to -the longitudinal axis of an upper substantially straight section of the housing. The shaping of the lower section takes the form of a first por-tion extending away from the longitudinal axis at a first angle and having a first pre-selected length and a second portion contiguous with the first portion having a second pre-selected length and extending back towards the longitudinal axis at a second angle rela-tive -to the first portion. The first and second pre-seleted lengths and the first and second angles are selected to position the writing tip at a pre-selected distance from the longitudinal axis.
In an alternative embodiment of the invention, the first and second portions are not co-planar and the angle of the second por-tion is selected to further position the writing tip at a third angle relative to the longitudinal axis and to one side of the plane of the housing defined by the first portion and the upper straight section of the housing.

3~3 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As can be seen from Figures 1 and 2, the pen shown generally as 10 comprises housing shown generally as 12, ink reservoir means shown generally as 14, writing tip shown generally as 16, and retracting means shown generally as 18.
With particular reference to Figure 2, ink reservoir means 14 comprises a long tubular flexible ink reservoir 15 which is mated to writing tip 16. Ink reservoir 15 is a long flexible tube which is easily bent and deformed. In a' preferred embodiment, wri-ting tip 16 comprises a ball-point writing tip. Housing 12 is a long tube-like structure which tapers to writing end 20 having aperture 22. Housing 12 has chamber 24 and flexible ink reservoir 15 is adapted to fit within chamber 24. Writing tip 16 is configured to project through aperture 22.
Retracting means shown generally as 18 preferably comprises a push button 36 which engages reservoir 15 which in turn is blased by spring 38. When push button 36 is depressed, reservoir 15 is pushed down through chamber 24 and writing tip 16 is extended out of aperture 22. A
mechanism is provided within housing 12 for holding the reservoir in this position when push but-ton 36 is released.
Such mechanisms are:well known in the art and may comprise a :
thrust tube/rotating sleeve arrangement, a ball and cam !

mechanism or some other mechanism. Which ever mechanism is used, when push button 36 is depressed and released again writing point 16 is drawn into chamber 2~ by the recoil action of biasing spring 38. In order to facilitate the manufacture of these retractable pens, housing 12 is formed in two pieces which can be separa-ted to permit the replacing of reservoir 15 when the ink contained therein is exhausted.
Referring to Figure 1, housing 12 has an upper straight section 26 having a longitudinal axis shown by dotted line A. Lower section 28 of housing 12 ad~acent apertured 22 is shaped to reposition wri-ting tip 16 relative to longi-tudinal axis A. Lower shaped section 28 comprises first portion 30 and second portion 32. Firs-t portion 30 is continguous with upper straight sec-tion 26 and has an axis of its own defined by dot-ted line B. First portion 30 extends away from longitudinal axis A a-t first angle R.
Second portion 32 is contiguous with first portion 30 and has also an axis of its own as shown by dotted line C.
Second portion 32 extends back towards -the longitudinal axis A at second angle S relative to axis B. First portion 30 and second portion 32 have a first pre-selected length and a second pre-selected length respectively. The first and second pre-selected lengths and angles R and S are selected to position writing tip 16 at pre-selected distance 34 from longitudinal axis A. In the preferred embodiment, axes A, B
and C are co-planar, and angle S is selected so that axis C
~ .
; ~
' .
73~
intersec-ts axis A at -third angle T resulting in writing tip 16 being positioned at third angle T relative to longitudinal axis A.
Preferably, first angle R is between 15 to 30, second angle S is between 10 to 30, third angle T is between 5 to 15, the lengths of first portion 30 and second por-tion 32 are between 2 -to 4 cm and 1 to 3 cm respectively, the ]ength of first portion 30 being greater than second portion 32. In the preferred embodiment, R is about 12, S is about 20 and T is about 8.
As shown in Figure 3, in a preferred embodiment, the bending of the lower section 28 of pen 10 -takes place in a single plane, i.e. axes A, B and C are in a single plane.
However, as shown in Figure 4, in an alternative , "right handed" embodiment, shown generally as 40, second portion 42 of lower housing section 44 is bent relative to - first portion 41, resulting in axis C1 of second portion 42 not being in the plane defined by first portion 41 and upper stright housing section 48, such plane extending out of the page towards the reader. This bending of lower portion 42 results in writing tip 47 being positioned at angle V
relative to the longitudinal axis A at a distance of between about 1 to about 3 mm from the aforesaid~plane.
This alternative embodiment would be particularly useful as :
~ - \
a writing implement for right handed people because it posltions -the writing tip towards the user and therefore the user can better see the writing tip and also results in less hand strain.
Referring now to Figure 5, in yet another alternative embodiment of -the invention shown generally as 50, second portion 52 angles away from first portion 51 so that the axis of second portion 52 as shown by dotted line E
intersects the plane defined by upper housing section 58 and first portion 51 of lower housing section 54 at angle W as shown in Figure 5. This alternative embodiment would be particularly useful for people who are left handed.
In opera-tion, the writing tip is first extended out of aperture 22 by depressing push button 36. Housing 14 is then grasped such that the thumb of operater rests agains-t the point 35 near the junction of longitudinal portion 26 and first portion 30 and the third finger of the same hand rests against point 37 near writing end 20 of pen 10. Because writing tip 16 is positioned a-t pre-selected distance 34 from longltudinal axis A, and at third angle T
relative to longitudinal axis A, pen 10 can be held comortably in the hands, while at the same time positionlng writing tip 16 at an angle which is steeper than the angle between the paper and the longitudinal axis of the upper part of the pen housing.
~ ~: : . , ,, ~
This positioning of writing tip 16 facilitates the free flow of ink, particularly if writing tip 16 comprises a ball-point. Furthermore, because of the shape of first portion 30 and second portion 32 of lower section 28, flexible ink reservoir 14 can slide rreely within chamber 2~, and therefore housing 12 could be utilized wi-th standard flexible ink reservoirs having standard ball-points mated thereto. Also, because of the shape of housing l~ and the resulting orientation of the thumb and third finger when the pen is held in a writting position, the pen is more comfor-table to hold. The lessening of the strain together with the generally more comfortable grip associated with pen 10 makes the use of pen 10 more comfortable in the hands of operators suffering from ar-thritis of the hands.
Although a retractable ball-point pen is illustrated in Figures 1 through 5, it is clear that the present invention may also comprise non-retractable pens having one piece or two piece bodies which use ball-point or felt tipped writing tips. In embodiments where no retracting means is provided, the writing tip is rigidly retained by the housing such that it rigidly extends out through the aperture. A cover or cap may be provided -to cover over the writing tip when the pen is not in use.
Furthermore, all of the angles and pre-selected length may be modified to bet-ter conform the shape of the g ~ ~ . - ,. ~ ."

Second portion 32 is contiguous with first portion 30 and has also an axis of its own as shown by dotted line C.
Second portion 32 extends back towards -the longitudinal axis A at second angle S relative to axis B. First portion 30 and second portion 32 have a first pre-selected length and a second pre-selected length respectively. The first and second pre-selected lengths and angles R and S are selected to position writing tip 16 at pre-selected distance 34 from longitudinal axis A. In the preferred embodiment, axes A, B

However, as shown in Figure 4, in an alternative , "right handed" embodiment, shown generally as 40, second portion 42 of lower housing section 44 is bent relative to - first portion 41, resulting in axis C1 of second portion 42 not being in the plane defined by first portion 41 and upper stright housing section 48, such plane extending out of the page towards the reader. This bending of lower portion 42 results in writing tip 47 being positioned at angle V
relative to the longitudinal axis A at a distance of between about 1 to about 3 mm from the aforesaid~plane.
This alternative embodiment would be particularly useful as :
