Title: Ring pen device

Description:
CROSS REFERENCE TO RELATED DOCUMENT 
   This invention was described in Disclosure Document Number 550367, which was received by the U.S. Patent &amp; Trademark Office on Mar. 31, 2004. 
   BACKGROUND OF THE INVENTION 
   1. Technical Field 
   The present invention relates to a ring pen device with a retractable, insertable pen assembly or the like that can be worn on the finger as a conventional finger ring, or removed and used as a writing implement. 
   2. Background Information 
   Oftentimes, a conventional pen will leak ink into the shirt pocket where it is kept, or onto adjacent items in a handbag or briefcase. This can ruin an expensive shirt or handbag. Also, a forgotten pen left in a student&#39;s pants pocket, for example, can leak in the washing machine. Men, women, and children have a tendency to misplace conventional pens in their pockets, handbags, book bags, car trays, and elsewhere. Then they have to spend an inordinate amount of time searching for a writing implement when they need it, often to no avail. Other people are often inconvenienced, too, such as the person waiting on the other end of a cell phone to provide a name, address, or phone number. Thus, there is a need for an easy to use writing implement that is unlikely to leak and cause damage, and is always readily available. 
   BRIEF SUMMARY OF THE INVENTION 
   The present invention is a ring pen device that is convertible between a use as a finger ring and a writing implement. The instant ring pen device includes: (a) a ring hull; (b) a hull insert within the ring hull, which includes a channel; and (c) an extendible pen assembly within the hull insert, which includes at least one ink tube. The pen assembly has a retracted position within the hull insert, and an extended position in which a portion of the ink tube is extended from an end of the channel in the hull insert. The pen assembly preferably further comprises a slide bar adjacent the ink tube, and at least one pair of matching slide bar stops extending from the slide bar on either side of the ink tube. The slide bar preferably includes a central section, a lower section attached to the ink tube, and a flexible section. The hull insert is preferably affixed to the ring hull, and comprises a cavity and at least one pair of notches in the hull insert. Each slide bar stop is insertable in at least one of the notches. 
   The ring pen device of the present invention overcomes the problem of digging for a writing implement in the bottom of a pocket, handbag, briefcase, knapsack, glove compartment, etc. Since a conventional pen or pencil is often difficult to locate, the ring pen device of the present invention is advantageous in that it provides the wearer with fast and easy access to a pen. At the same time, it is a stylish and novel accessory. Since it is worn on the user&#39;s finger, it is unlikely to be lost. The present ring pen device is particularly useful for the person on the go, such as a student, traveler, tourist, or salesperson, who must juggle his or her supplies or undertake other activities while attempting to take notes quickly.

   DETAILED DESCRIPTION OF THE INVENTION 
   In the following description, like reference characters designate like or corresponding parts throughout the several views. Also, in the following description, it is to be understood that such terms as “front,” “back,” “within,” and the like are words of convenience and are not to be construed as limiting terms. Referring in more detail to the drawings, the invention will now be described. 
   Referring to FIGS.  1 A–C and  2 A–C, a retractable ring pen device, generally referred to herein by reference number  10 , may be worn as a finger ring and also utilized as a miniature pen. As shown in  FIG. 1C , the ring pen device  10  is worn around a user&#39;s finger  24 , though preferably not the thumb, with its pen assembly  13  in a retracted position when it is not being used as a writing implement. When the user desires to use the pen assembly  13  to jot down a name and telephone number, for example, as shown in  FIG. 2C , the ring pen device  10  is removed from the finger  24  and held between the thumb  43  and forefinger  42  so that the user may write. This allows for a comfortable writing position and mimics the way a conventional pen is normally held. After use, the ring pen device  10  can be placed back on the finger  24 , where it is readily accessible for the next time a writing implement is needed. 
   As shown in  FIGS. 3 and 4 , a preferred embodiment of the ring pen device  10  comprises a ring hull  11 , a hull insert  12 , a pen assembly  13 , and a ball point pen tip assembly  14 . Referring to  FIG. 4  and also  FIGS. 5A–C , the ring hull  11  is comprised of a band portion  15  and a pen portion  17 . The band portion  15  extends out from opposite faces  21 ,  22  of the pen portion  17  to form a circular shape that fits around a user&#39;s finger. In use, a user&#39;s finger is insertable through the generally circular aperture  16  extending through the circular band portion  15 . The pen portion  17  is preferably generally rectangular in shape and has the following generally planar faces, which form a hollow: front face  18 , top face  19 , bottom face  20 , left face  21 , right face  22 , and open back face  23 . The open back face  23  faces the band portion  15  and is opposite the front face  18 . The hull insert  12  is receivable through the open back face  23  of the pen portion  17 . 
   Referring to FIGS.  4  and  6 A–D, the hull insert  12  is insertable in the inside hollow of the pen portion  17 . The hull insert  12  is therefore also generally rectangular in shape and similar in size to the hollow. The hull insert  12  is comprised of the following generally planar faces: two, opposed insert left and right side faces  47 ,  48 , an insert bottom face  38 , a partially open insert top face  37 , an insert front face  49 , and an open insert back face  51 . The faces  37 ,  38 ,  47 ,  48 ,  49 ,  51  surround a uniquely shaped cavity  34 , which receives the pen assembly  13 . Lower and upper notches  35 ,  36  in the insert back face allow the pen assembly to operate and contain the pen assembly  13  in the hull insert  12 . 
   To assemble the ring hull  11  and the hull insert  12 , the manufacturer of the pen assembly glues or otherwise inserts the hull insert  12  into the hollow pen portion  17  of the ring hull  11  through its open back face  23 . Within the pen portion  17 , the insert front face  49  lies flush against the rear side of the front face  18  of the pen portion  17 , and the open insert back face lies flush with the open back face  23  of the pen portion  17 . Correspondingly, the insert left and right side faces  47 ,  48  lie adjacent to the left and right side faces  21  of the pen portion  17 , respectively, and the insert top and bottom faces  37 ,  38  lie adjacent to the top and bottom side faces  19 ,  38  of the pen portion  17 , respectively. 
   Referring to FIGS.  4  and  7 A–D, the pen assembly  13  is slidable into and out of the hull insert  12 . The pen assembly  13  is comprised of a slide bar  27 , a tube  28  containing ink or another suitable marking substance adjacent the slide bar, and a pair of matching slide bar stops  33  on either side of the marking tube  28 . The marking tube is preferably ink-filled. The slide bar stops  33  are preferably substantially identical. The slide bar  27  is generally rectangular in shape and the ink tube  28  is hollow and generally cylindrical in shape. The slide bar  27  comprises a central section  29 , a lower section  31  where the slide bar attaches to the ink tube  28 , and a flexible section  30  (see  FIG. 7B–D ). An ink assembly aperture  41  extends along the longitudinal center of the ink tube  28  for receiving ink and the ball point tip assembly  14  (see  FIG. 7D ). 
   To insert the pen assembly  13  into the hull insert  12 , the user slides the lower section  31  of the ink tube  28  of the pen assembly  13  into the substantially similarly shaped cavity  34  in the hull insert  12  through the partially open top end  37  (see  FIG. 4 ). The ink tube  28  fits into the cavity  34 , which is molded to accommodate the ink tube  28 . As the lower edge of the lower section  31  of the pen assembly  31  approaches the bottom face  38  of the hull insert  12 , the slide bar stops  33  make contact with top edge of the back face  51  of the hull insert  12 . The bottom side of the notches are curved, so continuing to apply pressure to the lower end of the slide bar  31  causes the slide bar stops  33  to ride up on to the back face  51  of the hull insert  12  (see  FIGS. 6 and 7 ). This forces the flexible section  30  of the slide bar  31  to flex backwards. When the slide bar stops  33  reach the upper notches  35 , they snap into the upper notches. 
   The pen assembly  13  is now inserted into the hull insert  12 . The pen assembly is in the extended position (see  FIG. 2B ). Applying pressure by pushing the pen assembly  13  toward the insert bottom face  38  forces the slide bar stops  33  out of the upper notches  35 , which again causes the flexible section  30  of the slide bar to flex backwards. Continuing to apply pressure to the slide bar forces it down toward the insert bottom face  38 . When the lower section  31  of the pen assembly  13  reaches the bottom face  38  of the hull insert  12 , the stops  33  will be aligned with the bottom set of notches  36 . The slide bar stops  33  will snap into the bottom notches  36 . The pen assembly  13  is now at rest in the retracted position, as shown in  FIG. 1B . 
   To use the ring pen device  10 , the user moves the pen assembly  13  to the extended position, applies pressure to the lower section  31  of the slide bar  27 , pushing the pen assembly  13  toward the top face  19  of the hull insert. This forces the slide bar stops  33  out of the bottom notches  36 , which are curved to allow this action, and up onto the back face of the hull insert  51 . Continuing to apply pressure will move the pen assembly toward the insert top face  37 . When the stops  33  reach the upper notches  35 , they snap into the upper notches  35 . The pen assembly is now in the extended position, as shown in  FIG. 2B . 
   The topside of the upper notches  35  are made on approximately a 90 degree angle in relation to the movement of the pen assembly  13 . The upper notches  35  are similarly shaped in order to provide a stop for the pen assembly  13 . This prevents the pen assembly  13  from being pushed out of the hull insert when the pen assembly  13  is moved from the retracted position to the extended position. 
   To remove the pen assembly  13  from the hull insert  12 , the user starts with the pen assembly  13  in the extended position. While gently applying pressure on the lower end of the slide bar  27  in the direction of the insert top face  37 , the user lifts up slightly on the end of the slide bar. This pulls the slide bar stops  33  out of the upper notches  36 . The pen assembly  13  will now slip out of the hull insert  12 . 
   When the ring pen device  10  no longer works, it may be disposed of appropriately and easily replaced, since it is inexpensive. An alternate embodiment is refilled by removing the pen assembly and replacing it with a new one. 
   Turning to  FIGS. 8A–B , a preferred ball point tip assembly  14  is comprised of an upper ink barrel section  39   a  and a lower ink barrel section  39   b  joined by a stop ring  40 . The ink barrel sections  39   a ,  39   b  are substantially longitudinally oriented. The lower ink barrel section  39   b  has a greater diameter than the diameter of the lower ink barrel section  39   a . The lower ink barrel section  39   b  fits the ink tube  28 . The stop ring  40  prevents the barrel from sliding up into the ink tube  28 . The upper ink barrel section  39   a  forms the writing tip. 
   To use the ring pen device  10  as a pen, the user simply slides the pen assembly  13  longitudinally through the cavity  34  so that the stops  33  disengage the lower notches  36  and engage the upper notches  35 . As a result, the pen assembly  13  is in the extended position as shown in  FIGS. 2A–C ; the upper ink barrel section  39   a  extends from the top face  37  of the ring hull  11 . Then, in order to write, the user inserts his or her forefinger  42  through the band aperture  16  and holds the ring portion  17  between his or her forefinger  42  and thumb  43 , so that the front face  18  faces the user and the upper ink barrel section  39   a  points in a generally downward direction. As the user writes, ink  44  from the marking tube  28  flows through the lower ink barrel section  39   b  out of a tip  45  of the upper ink barrel section  39   a , and onto the writing surface  46 , as shown in  FIG. 2C . The word “ink” as used herein means any type of writing medium including pen ink. 
   To wear the ring pen device  10 , the user gently slides the pen assembly  13  back into the cavity  34 , so that the slide bar stops  33  disengage the upper notches  35  and engage  36  the lower notches  36 . As a result, the entire pen assembly  13  is in a retracted position within the cavity  34 , where the upper ink barrel section  39   a  is concealed by the top face  37  of the ring hull  11 , as depicted in  FIGS. 1A and 1B . Then the user inserts his or her ring finger  24 , or any other finger, through the aperture  16  with the pen assembly  13  lying against the top side of his or her finger between the hand and the finger knuckle. 
   According to the preferred embodiment of the of the ring pen device  10 , the hull insert  12  is fixed in the pen portion  17  of the ring hull  11 , the pen assembly  13  is removably insertable in the cavity  34  of the hull insert  12 , and the ball point tip assembly  14  is affixed in the pen assembly aperture  41  of the pen assembly  13 . 
   The ring hull  11  is preferably made of a precious metal, such as gold or silver, for durability and attractiveness. The hull insert  12  is preferably made of a durable plastic material. The pen assembly  13  is preferably disposable, inexpensive, and easy to manufacture. The hull insert  12  and the pen assembly  13  may be constructed from plastic. Having a ring hull  11  separate from a hull insert  12  is advantageous in that the ring pen device is less costly and lighter in weight when the ring hull is made of a precious metal and the hull insert is made of a plastic material rather than the precious metal. 
     FIG. 3  shows an alternate embodiment of the ring pen device  60 , in which the hull insert  12  is integral with the ring hull  11 . In this embodiment, both the ring hull  11  and the hull insert  12 , which form a ring hull/hull insert  50 , are preferably made of a durable plastic. An integral ring hull  11 /hull insert  12  is advantageous in that it is inexpensive to manufacture. 
   The band portion  15  of the ring pen device  10 ,  60  can be made in a variety of different sizes (i.e., the circumference of the band portion  15  can be manufactured in different lengths), or the band portion may be adjustable so that it fits different fingers of different users, as in the embodiment  70  shown in  FIG. 9 . As illustrated in  FIG. 9 , the ring hull  11  has an adjustable band  52 , which is non-contiguous. A first band section  53  projects from the left (or first) face  21  of the ring hull  11 , and a second, mirror image band section  54  projects from the right (or second) face  22  of the ring hull  11 . A gap  55  between the two band sections  53 ,  54  allows for adjustment. In use, these band sections  53 ,  54  flex slightly about the two faces  21 ,  22 . To decrease the circumference of the adjustable band  52 , the user pushes the band sections  53 ,  54  together into the gap  55 . To increase the circumference of the adjustable band  52 , the user pulls the band sections  53 ,  54  away from one another, thus increasing the gap  55  and the fit. 
     FIGS. 10–14  depict alternate embodiments of the ring pen device of the present invention, in which the pen portion  17  is not generally rectangular in shape.  FIGS. 11 ,  12 , and  13  illustrate a ring pen device with a pen portion  17  that is generally ovular in shape, while  FIG. 15  illustrates a ring pen device with a pen portion  17  that is generally circular in shape. Other shapes may also be used. In the embodiments shown, the pen portion  17  still comprises a generally planar, open back face  23  so that it rests substantially flush against a user&#39;s finger when worn by the user. Whatever the shape of the pen portion  17 , it accommodates a hull insert  12 . The ring pen device may include decorative objects or designs on the front face  18  of the pen portion  17 . These objects or designs may be integral with or attached to the front face  18 . Exemplary designs include a butterfly shape  56 , as shown in  FIG. 10 , a personalization  57  (e.g., user&#39;s name or initials) or other word, as shown in  FIG. 11 , and interlocking hearts  26 , as shown in  FIG. 1A . Exemplary objects include at least one jewel or stone (natural or imitation)  58 , shown in  FIGS. 12 and 14 . Of course, the front face  18  of the ring hull  11  need not include any object or design. 
   As shown in the alternate embodiment  80  of  FIG. 15 , an alternative type of marking assembly may be employed instead of a ball point tip assembly  14 , such as a felt tip assembly, a marker assembly  81 , and a roller tip ink assembly. Included in the present invention is a ring pen kit for assembling a ring pen device. The ring pen kit comprises: (a) a ring hull  11 ; (b) a hull insert  12  insertable in a cavity  34  in the ring hull  11 ; (c) a detachable, extendible pen assembly  13  within the hull insert  12 ; (d) a detachable, extendible felt tip assembly; (e) a detachable, extendible marker assembly  81 ; and (f) a detachable, extendible roller tip ink assembly. The hull insert  12  comprises a channel  32 . The pen assembly  13  comprises at least one marking tube  39 , as described herein, preferably an ink-filled tube made of plastic or the like. Each of the assemblies (pen, felt, marker, roller) has a retracted position within the hull insert  12 , and an extended position in which a marking portion of the assembly, such as the ink tube  39  of the pen assembly  13 , extends from an end of the channel  32  in the hull insert  12 . As described herein, the hull insert  12  comprises at least one pair of notches  35 ,  36 , the pen assembly  13  comprises a slide bar  27 , the slide bar  27  comprises at least one pair of matching stops  33  extending from the slide bar  27 , and each slide bar stop  33  is removably engageable with one of the notches  39 . 
     FIGS. 16 through 18  depict an alternate embodiment  90  of the ring pen device of the present invention, which comprises a ring hull  11 , a hull insert  91 , a pen assembly  92 , and a ball point pen tip assembly  14  (see  FIG. 16 ). The ring hull  11  is comprised of a band portion  15  and a pen portion  17 . The band portion  15  extends from opposite faces  21 ,  22  of the pen portion  17  to form a circle that fits around a user&#39;s finger. The band portion  15  has a generally circular aperture  16  extending through it for accommodating a user&#39;s finger. The pen portion  17  is generally rectangular in shape and has the following generally planar faces: front face  18 , top face  19 , bottom face  20 , left face  21 , right face  22 , and open back face  23 . The open back face  23  faces the band portion  15  and is opposite the front face  18 . 
   The pen assembly  92  of this slide arm embodiment  90  is slidable into and out of a slide arm hull insert  91 . The slide arm hull insert  91 , which is receivable through the open back face  23  of the pen portion  17 , may be integral with the ring hull  11 , or it may be detachable from the ring hull. The slide arm pen assembly  92  is comprised of a slide bar  27  attached to an ink tube  28 . The slide bar  27  is generally rectangular in shape and the ink tube  28  is hollow and generally cylindrical in shape. 
   The slide bar  27  is comprised of a central section  29 , a lower section  31 , and two flexible, matching side arms  93 , as shown in  FIGS. 16–18 . Both the central and lower sections  29 ,  31  of the pen assembly are generally rectangular in shape, with the lower section  31  having a width slightly greater than a width of the central section  29 . The slide arms  93  protrude from an upper end of a central section  29  and extend longitudinally along the length of the central section  29  and are separated by channels  32  from the central section  29 . Two mirror image slide arm stops  94  project substantially perpendicularly from the slide arms  93  away from the channels  32  and the central section  29 . Likewise, the lower section  31  protrudes from a lower end of the central section  29 . The ink tube  28  is affixed to a rear side of the slide bar  27  and extends between the upper end of the central section  29  and the lower end of the lower section  31 . A preferred ball point tip assembly  14  is comprised of an upper ink barrel section  39   a  and a lower ink barrel section  39   b  joined by a stop ring  40 , as described herein. 
   As shown in  FIG. 16 , the slide bar  27  fits into a first part of the cavity  34 , which is molded to accommodate the slide bar  27 , and the ink tube  28  fits into a second part of the cavity  34 , which is molded to accommodate the ink tube  28 . In use, as the lower edge of the lower section  31  approaches the bottom face  38  of the slide arm hull insert  91 , the slide arm stops  94  contact the top side  37  of the hull insert  91 . The user then exerts a downward force on the slide arm pen assembly  92 . Due to the curvature of the slide arm stops  94 , the slide arms  93  flex slightly inwardly into the channels  32  when the slide arm stops are pressed against the top face  37 . The slide arm stops  94  clear the top end  37 . The user continues to push the pen assembly generally downward into the cavity  34 . The walls of the cavity  34  continue to retain the arms in the channels  32  and the stops  94  continue to slide by the sides of the cavity  34  until they reach the upper notches  35 . Upon alignment of the slide arm stops with the upper notches  35 , inwardly directed pressure is no longer exerted on the stops  94 ; thus, they move out of the channels  32  and engage the upper notches  35 . At this point, the pen assembly is ready for use in an extended position, as shown in  FIG. 18 . 
   Again the user exerts generally downwardly directed pressure on the pen assembly  92  so that the walls of the cavity exert generally inwardly directed pressure on the slide arm stops  94 , the slide arms  93  flex into the channels  32 , the slide arm stops  94  disengage the upper notches  35 , and pen assembly  92  slides further down into the cavity  34 . Upon alignment of the slide arm stops  94  with the lower notches  36 , the walls of the cavity  34  no longer exert generally inwardly directed pressure on the slide arms  93 , and the slide arm stops  94  engage the lower notches  36 . At this point, a lower edge of the lower section  31  contacts the bottom side  38  of the hull insert  12 , and the pen assembly  92  is in the retracted position, as depicted in  FIG. 17 . 
   From the foregoing it can be realized that the described device of the present invention may be easily and conveniently utilized as a ring pen device for dual use as a piece of jewelry and a writing implement.
