Description

IMPROVED ADVERTISING BALL POINT PEN

BACKGROUND OF THE INVENTION

1. Field of, the Invention This invention relates generally to a writing instrument that can be used_, for indicia display, such as for advertising, and specifically to a writing instrument, such as a ball point pen, that has two or more optical displays produced by a lenticular lens display system affixed to the outer surface of the writing instrument housing,

2. Description of Related Axt

Writing instruments have long been, utilized as a popular form of advertisement for businesses. In particular, often a corporate name or logo is printed on the surface of a writing pen. U.S. Patent 5,086,577 issued to Abernethy February 11, 1992 shows a writing instrument advertisement device. ϋ\S. Patent 4,787,161 issued November 29, 1988 to Feng shows an advertisement writing instrument that can clamp to a user' s pocket for display.

It is also desirable for a writing instrument such as a ballpoint pen to have a non-slip surface for ease in writing when grasping a pen body in the hand and digits of the user.

The present invention ^" provides fo ^" an improved writing instrument such as a ballpoint pen, ink pen, pencil or stylus that also has two or more viewable indicia displays including pictorial, graphic or alphanumeric information disposed on the outside body of the writing instrument for informational, advertising, or entertainment purposes. Advances in the design and manufacture of lenticular optical systems have lead to the increased use of lenticular lens arrays . Lenticular lenses are well known in the art for use in optical systems to produce various types of optical affects. A lenticular optical system in the prior art generally includes a transparent sheet having a planar surface on one side and on the other side, a series of parallel, longitudinal, convex curved ridges 'separated by parallel grooves forming a multi lenticular system of convex lenses. A printed sheet of indicia is typically disposed behind the lens adjacent to the planar surface. The printed sheet contains at least two alternative series of spaced image lines constituting a dissection or break-up of a master image. The series of spaced image lines are optically related with ^• respect to the lens elements as to be alternately visible upon positional changes of the observer with respect to the lenses and images. When viewed from a first position, a first series of image lines are visible and a first composite image is observed. When viewed from a second position, a second (different) series of image lines are visible and display a second (different) composite image, U.S. Patent 2,815,310 issued to Anderson discloses an example of a dual image lenticular optical system.

Further advances in lenticular optical systems have resulted in an increasing of observable sets of images available. The increase in observable sets has made lenticular animation possible. Therefore, as the observer moves relative to the lenticular lens array viewing screen, a series of pictures comes successively into view thus creating the impression of continuous changes in the phases of motion. Accordingly, current lenticular optical technology is capable of producing a composite image in a series of N scenes resulting in an animation picture when viewed properly at successive viewing angles. In addition such technology may be used to display a wide variety of useful information, such as account information, telephone numbers, and e-mail addresses, as examples. The production of images which change with a change in viewing angle has been known for many years. It is described, for example, by A.G. Anderson in U.S. Patent No. 2,815,310, The images are produced on opaque or transparent sheets of material such as paper, paper board, or plastic. The resulting imprint, in black and white or color, is laminated to a transparent lenticular lens. Alternatively, a transparent plastic carrier may be printed on its reverse side and viewed through a lenticular lens face of the carrier. A lenticular screen, as is well known, has a number of

75 lenses arranged in side-by-side relationship. Each lens, commonly termed a lenticle, may be formed by an elongated or circular convex frontal surface, and a flat rear surface,

The printed image is formed by two interleaved pictures producing a grid of parallel lines with alternating striations.

80 The pitch, or number of picture-element pairs per unit distance, must be the same as the lens pitch of the lenticular array. In addition, the focal length of each lenticle should be equal to the thickness of the lenticular sheet. Under these conditions, at one viewing angle an observer will see only one

.85 picture, while at a different angle the same observer will see the other picture.

The requirement that the picture elements be in registration with the lenticular array complicates the printing and lens forming steps. In practice, the pitch of the

90 lenticular assembly is limited to a spacing that is equivalent to 100 lenticles per inch, or less. Even with 50-100 lenticles per inch, it is difficult to hold the registration over widths of more than a few inches. This limitation restricts the quality of pictorial resolution, as well as size. 95 The focal length of the lenticles must equal the thickness of the lenticular -sheet, At -a pitch of 100 lenticles per inch, assuming a half cylinder lenticular surface, the focal length for a conventional plastic sheet, having refractive index of 1,5 to 1.6 is 0,016 to 0.019 inches.

100 Currently there exists a need for a writing instrument such as a ball point pen that can be used to display advertisements _(ι and to have multiple different image displays available on a single instrument. The lenticular lens surface grooves are non- slippery, which aid in gripping or holding the writing

105 instrument while writing with the hand and digits. This is caused by a plurality of convex lens surfaces that are separated by lenticular lens grooves that are circularly presented around the body of the writing instrument such as a ballpoint pen.

110 BRIEF SX3I4MRΪ OF THE INVENTION

A writing instrument such as a ball point pen that includes a substantially cylindrical elongated housing, a barrel that is ^< an ink reservoir and projecting from one end of the barrel, a ball point writing tip. A barrel support is disposed within the

115 elongated tubular housing. A pen tip activating mechanism including an activating cap allows the ball point tip to be retracted or extended from one end of the housing manually.

Attached to the outer surface of the tubular housing is a lenticular lens dual image display system that includes a

120 plurality of convex lens surfaces separated.by circular grooves dispersed laterally around the pen body outer surface. The lens material is a translucent and clear plastic. Disposed directly on the outside body surface of the pen or on the planar lower surface of the lens body is the indicia images used with the

125 lenticular lenses that includes two separate ink images critically aligned relative to the lenticular convex lens surfaces such that an observer would be able to observe at least two visual images or pictures disposed on the portions of the ball point pen exterior surface by relatively moving the pen

130 body with respect, to the observer's point of view (eyes), Therefore, the ball point pen tubular body includes, attached to its outer surface of the pen housing, a lenticular lens array and at least two diff rent images , The lenticular lens^' array forms a lenticular optical system capable of displaying animated

135 images, alpha numeric information, advertising material, or other useful information. The actual image lenses may be on paper, glued to the pen body or painted directly on the surface of the pen or lens. The invention may include at least a portion of the pen body surface that comprises a transparent

140 lenticular display.

The ball point pen and ink transfer to paper operates in a normal way, while the lenticular lens optical system also helps holding the outer pen surface because of the lenticular circular grooves disposed parallel to the cross section of the pen body

145 length. The grooves are spaced apart in such away as to aid and improve non-slip on the grasping surface for the hand and digits for holding the pen. The pen may also include a rubber holding portion near the tip for the extreme ends of the thumb and index finger while holding the pen near the tip.

150 It is an object of the present invention to provide a writing instrument, such as a ballpoint pen, that includes a lenticular lens optical display system on its outer body for indicia display.

Another object of the present invention is to provide a

155 writing instrument that includes an lenticular lens array capable of displaying a wide variety (at least two or more) of images and/or information on the outside surface of the writing instrument body.

Yet another object of the present invention is to provide a

160 manual writing instrument with an lenticular lens array that is manufactured to standard writing instrument specifications and sizes for use manually that includes dual image indicia and lenticular outer lens surfaces and grooves for non-slip grasping.

165 In accordance with these and other objects, which will become apparent hereinafter, the instant invention will now be described with particular reference to the accompanying drawings . 170 BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS

Figure 1 shows a side elevational view of the present invention with the ballpoint tip extended.

Figure 2 shows a front elevational view of the present invention as shown in Figure 1 with the ballpoint pen extended 175 rotated 90 degrees from the view of Figure 1.

Figure 3 shows an enlarged side elevational view of the present invention portion of its body for explanatory reasons.

Figure 4 shows a cut away segment of the surface of the ballpoint pen, the indicia disposed thereon, and a portion of 180 the lenticular lenses in cross section.

PREFERRED EMBODIMENT OF THE INVENTION Referring now to the drawings and in particular Figure 1, the present invention is shown generally at 10 including a ball

185 point pen tubular plastic or metal body 12 which is an elongated tube having a conical rubber or synthetic rubber-like grasping tip 30. The conical tip 30 may include a plurality of semi- spherical recesses oriented about the tip surface 30 for easier grasping. Inside of the ball point pen housing 12 is a barrel

190 20 which is an ink reservoir that has a ball point pen tip 28 connected at the end for writing purposes. The ballpoint pen 10 includes a mechanism inside the housing 12 which includes a spring lock so that manual depression of button 18 causes the ballpoint pen tip 28 to be retracted or extended depending on

195 the position of the mechanism. The ballpoint pen itself is conventional in operation and may include .a pocket clip-on 16. The housing 12 may be made of metal or plastic.

Affixed to the outer housing 12 is dual image indicia 24 and 26 which as an illustration shows a human set of lips both

200 open and closed. The open lips image indicia 24 show human teeth while image indicia 26 shows a pair of closed lips. The images 24 and 26 change when the pen body is moved relative to the observer's optical line of sight. These images 24 and 26 are disposed about the surface of the body 12 by painting or

205 gluing paper or plastic image indicia onto the outer surface 12. Disposed on top of the indicia 24 and 26 is a lenticular lens system having convex lenses 14 separated by grooves 22 that are disposed laterally around the circular body of the ballpoint pen 10. Each circular groove 22 basically forms a plane that is

210 perpendicular to the longitudinal axis of the ballpoint pen. Each of the grooves 22 extends circularly around and separates the adjacent convex lenses 14 forming the lenticular display system. Figure 2 shows the same view of the pen shown in Figure 1 only at 90 degrees therefrom again including indicia 24 and

215 26. Each image is made up of two sets of lines and contains both image 24 and image 26 at each image location. Moving the pen body produces movement of the lips 24 and 26 between an open lip display and a closed lip display, as results from the lenticular lens 14. For the sake of example, the lenticular

220 lens surface areas have been exaggerated in size and would be much, much smaller when observed. Also in Figure 2, the ballpoint pen writing tip shown in Figure 1 as element 28 has been retracted. Each pair of lips shown on the pen 10 in Figures 1 and 2 contain both images 24 and 26.

225 Referring to Figure 3, the ballpoint pen body 12 is shown in cross section but has affixed to its surface two different image lines 24 and 26 relative to each of the lenticular convex lenses 14. Basically when a person observes the image lines 24 or 26, because of the lenticular convex lenses 14 and their

230 separation by grooves 22, at one position the eyes would perceive one set of image lines 26 showing a pair of lips that are closed. Movement of the pen body relative to the observer would then show the same area but different image 24 that the lips are open and displaying teeth, Closing and opening motion

235 is also perceived by moving the pen body. Any types of two different images can be presented whether it is alphanumeric information, letters, corporate logos or other data that could be useful to someone that is utilizing the ballpoint pen.

As shown in Figure 3, the eye is capable of looking at

240 either indicia 26 or 24 depending upon the relative location of the ballpoint pen body. Note that in the drawings, the convex lens surfaces 14 and grooves 22 are exaggerated in size and are much smaller on the actual pen. The pen body lens surface exterior has a non-smooth

245 surface which aides in grasping a pen during a writing operation.

Figure 4 shows the pen body 12 having affixed to its outer surface indicia images 24 and 26 which are sized and used in conjunction with the lenticular optical system 14 at the same

250 area of the pen body. Lenticular convex lenses 14 are separated by the grooves 22 which allow an observer to see either the indicia image lines 24 or alternatively indicia image lines 26.

As stated in the above example, the images 24 and 26 are ^'an animated pair of lips in a closed position, which then opens to

255 an open position exposing the lips and teeth. Motion is detectable between the two images while changing the viewing angle. As diagra matically illustrated in Figures 3 and 4, the series of spaced image indicia lines 24 and 26 are optically related with respect to the lens elements as to be alternately

260 visible upon positional changes of the observer with respect to the lenses. For example, when viewed from a first observer position, a first series of image lines 24 are visible and display of a first composite image 24 is viewed. Specifically when viewed from another observer position, the optical lines of

265 sight are refracted by convex lenses 14 towards first image line so that the observer sees the image lines 24 coherently and comprehensively corresponding to the image presented by all first image lines. When viewed from a second observation position, a second series of image lines 26 are visible and

270 display a second composite image 26 overall. Similarly, when viewed from a second observation position, the optical lines are refracted by convex lenses 14 towards the second image lines 26 so that the observer sees a coherent and comprehensive image 2β corresponding to an image represented by the second image lines.

275 As previously discussed, advances in lenticular optical systems have resulted in an increase in the number of images that include animation for use with lenticular lenses . The increase in observer image sets has made- lenticular animation possible. Therefore as the observer moves relative to the

280 lenticular ^■ viewing screen, a series of pictures come successively into view, bringing the appearance of continuous changes in the phases of motion. Accordingly, to the extent that the disclosure and diagrammatic representation here may be limited to first and second image sets, the present invention

285 may include the use of large number of observable images such as to achieve animation. While the preferred embodiment of the invention contemplates a lenticular lens having a series of convex lenses, it is contemplated that any suitable lenticular lens structure within the scope of the present invention is

290 possible.

In an alternate embodiment and the lenticular lens may cover only a small portion of the ballpoint pen body surface for informational purposes.

Although the writing instrument shown here is a

295 conventional ball point pen, a fountain pen or pencil or other type of writing instrument including electronic devices could be utilized by affixing the proper lenticular lens system to the outer surface for display. Although the lenticular lens system is shown with the grooves running laterally circularly around

300 the ball point pen body, a lenticular pen display could be arranged so that the grooves run longitudinally along the outer surface which will change the viewing angle 90 degrees.

The instant invention has been shown and described herein in what is considered to be the most practical and preferred

305 embodiment. It is recognized, however, that departures may be made therefrom within the scope of the invention and that obvious modifications will occur to a person skilled in the art.
