Abstract
A pen holder (22) comprising six tapered tubular cavities (24) for holding and sealing various size pens, is formed in a resilient foam (28) cooperating with a skin (30) that surrounds all outside surfaces. The resilient materials are flexible enough to hold pens against the tapered section without loosening. Tapered tubular cavity (24) has a mouth (42) that is connected to a throat (44). Throat (44) leads to a primary gripping zone (46) that connects to a secondary gripping zone (48). The gripping zones have different tapered ranges to accommodate different pen widths. Foam (28) and skin (30) surrounds tapered tubular cavities (24) forming an outside block shape with a face (32) that comprises six mouths (42) exposed in face (32). Face (32) is parallel to a base (34). The block shape comprises two concave sides (36A) and (36B). Pen holder (22) comprises two waist walls (38A) (38B) that are perpendicular to concave sides (36A) and (36B). Pen holder (22) can be held in a human being's hand during operation or can be held by a wall bracket (62). In addition, pen holder (22) has an eraser well (26) that comprises two short walls (56A) and (56B) which are tapered to hold a conventional eraser (78). Eraser well (26) comprises two side walls (58A) and (58B) that are perpendicular to a end wall (60). End wall (60) is parallel to a port (54) which is exposed in face (32) of pen holder (22).
Description




BACKGROUND




1, Field of Invention




This invention relates to pen holders, specifically to such holders which are used for holding pens of various size.




2. Description of Prior Art




Pen manufacturers commonly supply consumers with pens that have different sizes, lengths, and degrees of slope along the pen length. Pen manufactures often equip pen models with a mating cap to prevent evaporation of ink.




These pens require the use of two hands for removing caps before writing. Conversely, after writing, the caps need to be installed to prevent drying of ink. However, writers objected because the act of using a cap in such a manner becomes tedious.




Thereafter, inventors created pen holders to facilitate one-hand operation for writing. U.S. Pat. No. 5,405,024 to Sahf (1995) discloses a complex rack with an internal groove for a ring seal. However, ink can easily contaminate the seal precluding the use of different colors of ink pens. U.S. Pat. No. 5,163,549 to Hayduchok (1992) shows a hollow rigid modular pen holder system. However, this system requires a close tolerance between the pen and the holder. U.S. Pat. No. 5,033,629 to Caine (1991) demonstrates a thin resilient cylindrical sleeve mounted in a rigid box. However, the round inner sleeve area has a static unbiased hole size. Thus, the seal must compress with ever greater pressure when pens of larger sizes are inserted . Also, pens must be kept in a upright position to prevent toppling precluding portable hand-held use of holder while writing. Finally, Caine's pen holder grips pens at the tip diameter increasing the risk of ink contamination. U.S. Pat. No. 4,493,575 to Mutschler (1985) employs an internal tapered sleeve attached at one end only. However, the sleeve can be pulled out of holder along with pen unless sleeve is rigid. U.S. Pat. No. to Kennamer 2,957,270 (1960) shows a solid block that slides on a track with a plurality of cavities therein. However, the solid block needs to be of a rigid low friction material so as to be able to slide on dovetail rib. U.S. Pat. No. 2,082,831 to Hansen (1935), U.S. Pat. No. 1,789,439 to Horix (1926), and U.S. Pat. No. 1,641,829 to Sheaffer Walter and Sheaffer Craig (1924) illustrate sleeves mounted to a base at one end. However, the sleeves need to be made of a rigid material to prevent collapse when pens are inserted. U.S. Pat. No. 2,011,040 to Cuthbert (1935) and U.S. Pat. No. 1,804,120 to Sengbusch (1927) document complex multiple part holders that use resilient gripping fingers to accommodate different size pens. However, these configurations would be prohibitively expensive to manufacture. U.S. Pat. No. 1,762,104 to Liddell (1928) divulges a sleeve attached at one end with a series of inner-stepped recesses. However, the shoulder of the pen abuts on top of the recess requiring gravity to maintain upright position. Also, holder cannot maintain pens in horizontal position without toppling and falling out. U.S. Pat. No. 1,641,846 to Fremon Jules and De Haven Avery (1927) embodies a rubber cylindrical sleeve with an internal shoulder and a flared open end. However, the shoulder of pen sits on top of the internal shoulder in a loose fashion thus requiring a vertical position. U.S. Pat. No. 1,620,529 to Ferris (1927) presents a rubber sleeve inserted into a base. However, the sleeve has an axial internal groove preventing an airtight seal. Also, different size pens are accommodated by using a new sleeve with mating size bore. U.S. Pat. No. 3,866,992 to Katz (1975) and U.S. Pat. No. 3,428,380 to Danjczek (1969) displays tubular elements seated in a container filled with water. However, tubular elements do not provide a perfect airtight seal. U.S. Pat. No. to 5,850,917 Denton (1998) shows a box with cavities therein. However, Denton teaches that his box is rigid and requires a foam liner to hold syringes of different diameters. Additionally, Denton explains that the holder is designed to hold syringes with a sterile cap over a hypodermic needle. Also, Denton's syringe holder does not compensate for the effect that various syringe widths have on the ratio of protruding syringe length to inserted syringe length. U.S. Pat. No. to 4,253,830 Kazen (1981) cites a resilient cylindrical tapered stepped sleeve inserted into a rigid box. Nevertheless, the sleeve encompasses a constricting aperture wall that results in an unbiased static hole. Also, Kazen has designed the holder to continuously vent to atmosphere so that dental instruments will not corrode in the holder.




All of the pen holders mentioned attempt to solve the objections of writers, nevertheless all of the pen holders heretofore known endure from a number of disadvantages:




(a) The tubular side wall of the holders in the present do not have a constant yielding frictional engagement with pens of different sizes. Such holders require ever increasing force to insert pens of larger sizes therein. Such increasing pressure on holder requires the use of reinforced fastening system to prevent holder from moving. Also, such holders are limited to permanent fixtures that will not move. Portable devices such as easels or tripods need to be permanently attached to the earth. Pens cannot be pulled out of the holder by grasping cap attached to end of barrel without detachment. Conversely, such holders cannot maintain minimum frictional engagement to facilitate pen release. Pens of smaller sizes result in ever decreasing holding force on pens. Smaller pens require the holder to be mounted in a vertical position to prevent pens from toppling or falling out. Also, such holders cannot maintain an airtight seal around pens of various size so that only minimum force is need to substantiate a perfect seal. Such holders do not readily allow consumers to buy different pen models which will work in such holders with consistent performance. Finally, variance in frictional engagement requires a writer to accommodate to different insertion and release pressures of various pens from holder.




(b) In present holders, the marking tips of pens can easily touch the inner wall of tubular holder. If one uses pens with different ink colors the holder must be cleaned prior to insertion. Such holders engage pens at their tip. The use of a plurality of holders with different color pens requires assignment of each pen to an exclusive holder to prevent cross contamination of ink. Such holders decrease writing speed when writers dedicate a specific color pen to an addressed holder.




(c) Present tubular holders do not compensate for the effect that various pen widths have on the ratio of protruding pen length to inserted pen length. Pens of narrow diameters will engage tubular holder deeper than pens of larger diameters. Consequently, a narrow diameter pen will have a greater percentage of its pen length inside the tubular holder than a larger diameter pen of comparable length. Accordingly, narrow pens require writers to reach a farther distance to grab pens verses a shorter distance for larger diameter pens. Reaching for pens of differing protruding lengths requires greater concentration for a writer.




(d) Pen holders of the present require the use of multiple parts and complex installations, thereby increasing cost and sales resistance for consumers. Also, multiple-part designs increase the chance for product defects.




(e) Pen holders of the present are limited to the use of rigid materials to prevent collapse. Rigid material requires that pen and holder be of mating dimensions to provide seal. Also, rigid material requires a snap fit. Mating surface between pen and holder require the use of different size holders for different size pens. The use of different size holders requires writers to put pens back in their assigned holder. Such holders require an exclusive model of pen to be used. Other pen models must remain with original caps precluding one-hand operation.




(f) The use of an internal shoulder to seat pens requires the use of gravity for pens to remain seated. Pens used in horizontal position will topple and not seat properly for airtight seal. Holders that provide annular stepped recesses to accommodate larger pens do not provide a constant yielding frictional engagement.




(g) Pen holders of the present do not allow writers or artists to handle pen holder in a palette-like fashion.




(h) Pen holders of the present do not allow writers to hold and squeeze holder in such a manner as to aid in tension release.




Objects and Advantages




Several objects and advantages that the present invention remedies are:




(a) to provide a holder which can accept many different pen models of different size with consistent performance.




(b) to provide a holder which prevents ink contamination by engaging various size pens at the barrel away from pen tip.




(c) to provide a holder which will compensate for the effect of various pen widths on the ratio of protruding pen lengths to inserted pen lengths.




(d) to provide a holder which is a singular molded part allowing for inexpensive rapid production with minimal installation for consumers.




(e) to provide a holder which is flexible with yielding properties that will hold pens of various size in a secure delicate fashion with airtight seal.




(f) to provide a holder which has a tapered tubular cavity without inner-stepped walls allowing pens to be gripped and held therein by a resilient yielding cushion in any position.




(g) to provide a holder that can be held like an artist palette to facilitate writing or drawing with various pens of different size and color.




(h) to provide a holder that can be held and squeezed to aid in tension release.




Further objects and advantages are to provide a holder which is extremely light weight, which is unbreakable, which can be attractively packaged in a clear plastic bag with reseal capabilities allowing consumers to inspect item, which requires inexpensive packaging decreasing cost for consumers, which uses inexpensive printed labels on package, which can be hung on peg board with minimal fixture support, and which can be supplied in master boxes of a standard size with lowest cost per cubic inch, without regards to total weight. Still further objects and advantages will become evident from observing the following description and drawings.

From the description outlined above, numerous advantages of our pen holder become evident:




(a) The same pen holder will be able to hold many different types of pen models, eliminating the need for manufacturing standards of pen size, length, and slope along the barrel. Thus, consumers can purchase pens based on other factors such as price, color, and style. With the use of a plurality of identical tapered tubular cavities to hold a infinite number of pen models, consumers will be able to use several different pen models concurrently without the need of returning a specific pen model to a exclusive tapered tubular cavity. Thus, writing speed will increase when several different pen models are used in conjunction.




(b) Tapered tubular cavities that grip various pen models away from the tip permit users to exchange pen models of different color into adjacent tapered tubular cavities, without the need to clean the inside of tapered tubular cavities. Thus, cross contamination of inks can easily be avoided.




(c) Tapered tubular cavities that compensate for the effect of different pen widths on protruding pen lengths, allow users to switch pen models of different widths into adjacent tapered tubular cavities without the sacrifice of appearance. Thus, uniform appearance of inserted pens is easily maintained. Also, pens that are uniform in appearance are easier to grasp because users do not have to reach between and below adjacent pens in order to grasp a narrow pen. Additionally, multi-tapered tubular cavities provides better support for pens by decreasing the variance depth at which different pen widths engage tapered tubular cavities. Pens of different widths engage multi-tapered tubular cavities near the center depth. Thus, the effect from different pen widths on the protruding height of pens is minimized.




(d) A single molded part requires no pre-assembly. Pen holders made in this fashion require less time per unit of manufacture. Also, single molded parts significantly reduce probability of defects.




(e) The use of foam to form tapered tubular cavities allows for an increase in tolerance between pen and tapered tubular cavity. Therefore, pens will suspend and seal against tapered tubular cavity even though the taper value of pen does not match taper value of tapered tubular holder, without the sacrifice of loosening or drying out. Pens can have a slope value that is zero, positive, or negative in comparison to tapered tubular cavity. Also, foam allows pen holder to resist breaking.




(f) The use of foam allows tapered tubular cavity to omit the use of a shoulder to seal the pen. Foam allows tapered tubular cavity to grip and suspend pen in any position.




(g) The hand-held capability of pen holder allows for superior ergonomic control for a user to insert and grasp implements. Users can naturally position pen holder so that the implements line up with the grasping hand.




Although pen holders made of rigid materials can be hand-held per se, the use of foam material in our pen holder will provide a pen holder that is light weight and comfortable with a nonslip surface.




(h) Pen holders made of foam material allow users to squeeze pen holder in the hand. This produces a custom fit in user's hand. Also, pen holder can be manipulated to aid in stress relief.

The manner of using pen holder


22


is similar to pen racks of present day use. Specifically, one first removes a cap from a pen and either discards cap or affixes the cap to the end of the pen barrel in normal fashion. As shown in

FIGS. 5A and 5B

(

FIG. 2

with implements added) chisel tip pen


76


is inserted into pen holder


22


with chisel tip


86


pointing toward tapered tubular cavity


24


until chisel tip pen


76


reaches a interference fit with tapered tubular cavity


24


. It is possible for one to insert a pen such as round tip pen


74


into pen holder


22


with pen butt


88


pointing toward tapered tubular cavity


24


with pen cap


90


covering round tip


84


. The interference fit of joint theta


92


of chisel tip pen


76


in

FIG. 7

(reference


7


of

FIG. 5B

) shows a deflection in tapered tubular cavity


24


of primary gripping zone


46


. The interference fit of joint delta


94


of round tip pen


74


in

FIG. 6

(reference


6


of

FIG. 5B

) shows a deflection in tapered tubular cavity


24


of secondary gripping zone


48


. As can be seen, the expansion of primary gripping zone


46


(

FIG. 7

) and secondary gripping zone


48


(

FIG. 6

) is similar in the amount of deflection between both tapered tubular cavities


24


. The uniform deflection pressure upon chisel tip pen


76


(

FIG. 7

) and round tip pen


74


(

FIG. 6

) allows for different pen models of various size and slope along the barrel to be inserted and removed from pen holder


22


with minimum force and consistent performance. The interference fit between the implements and tapered tubular cavities


24


is enough pressure for user to hold pen holder


22


in any position without the implements becoming loose from gravity or centrifugal force. The interference fit between tapered tubular cavities


24


and the implements produces an airtight seal around the implements.




To remove a pen inserted into pen holder


22


one simply grasps the exposed portion of a pen and pulls the pen loose from pen holder


22


as shown in FIG.


14


.




As shown in

FIG. 9

round tip pen


74


and chisel tip pen


76


are inserted into pen holder


22


with both round tip


84


and chisel tip


86


inside tapered tubular cavities


24


. It can be seen that the implements are tangent to tapered tubular cavities


24


with both round tip


84


and chisel tip


86


free and clear from the internal wall of tapered tubular cavity


24


.




In

.




To store eraser


78


(

FIGS. 10 and 12A

) in pen holder


22


one inserts eraser


78


into port


54


until eraser


78


becomes tangent with end wall


60


. When eraser

78


. The pressure applied to eraser


78


is enough pressure to hold eraser


78


firmly into eraser well

To temporarily hold pen holder


22


to a planar surface one can use a wall bracket


62


. Wall bracket


62


in

FIGS. 13A and 13B

is used to hold pen holder


22


against a planar surface. Wall bracket


62


can be mounted to a planar surface by a mechanical fastener such as a screw or nail (not shown). Wall bracket


62


can be attached to a planar surface by using a hook-and-loop or adhesive tape system (not shown). Through-hole


66


A and


66


B located at each end of plate


64


can be used to fasten wall bracket


62


to a planar surface. When wall bracket


62


is fastened against a planar surface, pen holder


22


can be inserted into wall bracket


62


using one hand. Tapered ends

22


at concave sides


36


A and


36


B. Channel walls


68


A and


68


B have slightly steeper taper than pen holder


22


causing an interference fit. The interference fit allows channel walls


68


A and


68


B to hold pen holder


22


tight enough to prevent gravity or centrifugal force from loosing pen holder


22


from wall bracket


62


(with implements inserted). Pen holder


22


can be removed from wall bracket


62


by grasping the exposed portion of pen holder


22


and sliding the holder against channel walls


68


A and


68


B toward the open end of the wall bracket


62


.




It is possible to temporarily fasten pen holder


22


to a planar surface without the use of wall bracket


62


by using a hook-and-loop fastening system (not shown). Also, pen holder


22


can be fastened to a planar surface by using an adhesive tape (not shown).




Pen holder


22


can be held like an artist palette as shown in

FIG. 14. A

writer or artist uses one hand to hold pen holder


22


. The other hand is free to grasp a pen, such as round tip pen


74


. Using pen holder


22


like an artist palette allows a writer or artist to remain in close proximity to pen holder


22


. The close proximity of pen holder


22


to its user allows a writer or artist to ergonomically control the position at which pens are selected. Pen holder


22


can be squeezed in an ergonomic manner to produce a custom fit in a users hand.




Summary, Ramifications, and Scope




Accordingly, the reader will understand that the pen holder of this invention can be used to hold pens easily and conveniently, can display pens in an ascetic manner, and can aid user in successive use of various pens. In addition, the pen holder can contour to a user's hand. Furthermore, the pen holder has the additional features in that:




it permits the use of various size pens without requiring a manufacturer to produce a specific pen model to use in conjunction with pen holder;




it permits the use of different color pens without the need to clean pen holder;




it counteracts the effect of various pen widths on protruding pen lengths inserted therein, providing a uniform appearance;




it allows rapid manufacturing techniques to be employed;




it provides reliability to hold and seal pens of various sizes;




it provides stability of inserted pens without the use of gravity;




it permits fluid movement for writers and artists to ergonomically control the position at which to grip pens from holder; and




it provides a pen holder that can be handled and squeezed to aid in stress relief of user.




Although the description above comprises many specific details, these should not be construed as limiting the scope of the invention but as simply providing illustrated examples of some of the presently preferred embodiments of this invention. For instance, the pen holder can have other shapes, such as trapezoidal, triangular, circular, etc.; the tapered tubular cavities could be more or less than six; tapered tubular cavity could have different degrees of slopes or be of a single tapered slope etc.; the eraser well can have bosses or cams to hold eraser inside the eraser well; and other implements beside pens can be used such as electronic probes, pencils, router bits, drill bits, etc.
