DETAILED DESCRIPTION OF THE INVENTION
Aside from the preferred embodiment or embodiments disclosed below, this invention is capable of other embodiments and of being practiced or being carried out in various ways. Thus, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of components set forth in the following description or illustrated in the drawings. If only one embodiment is described herein, the claims hereof are not to be limited to that embodiment. Moreover, the claims hereof are not to be read restrictively unless there is clear and convincing evidence manifesting a certain exclusion, restriction, or disclaimer.
Wrist writing apparatus 10, FIG. 1 of this invention, includes ergonomically shaped chassis 12 for attaching to the wrist of a user. Chassis 12 includes parallel plates 14 and 16 and is typically made of plastic or a similar type materials. Plate 14 includes curved surface 17 and lobes 18 and 20 with orifices 22 and 24, respectively. Plate 16 similarly includes curved surface 19 and lobes 26 and 28 with orifices 30 and 32, respectively. Curved surfaces 17 and 19 are shaped to ergonomically fit about the wrist of a user. Writing surface 32, FIG. 2, is connected between parallel plates 14 and 16. In one design, rotating shaft 34 is disposed through orifice 30, FIG. 1, in lobe 26 and through opposing orifice 22 in lobe 18. Core of a rolled writing substrate 38, e.g., rolled paper, is disposed about rotating shaft 34 (discussed below). Similarly, rotating shaft 40 is disposed through orifice 32 in lobe 28 and through opposing orifice 24 in lobe 20. One or both of rotating shafts 34 and 40 may be hollow for receiving a writing device. In this example, rotating shaft 40 is hollow and includes area 44 for receiving and securing a writing device. Similarly, rotating shaft 34 may be hollow and include area 49 for receiving a writing instrument. In other designs, rotating shaft 34 may be solid while rotating shaft 40 is hollow or rotating shaft 40 may be solid and rotating shaft 34 is hollow, or any combination thereof. In yet another design, both rotating shafts 34 and 40 are solid and a clip device is used to secure the writing instrument to chassis 12 (discussed below). Although as described above rotating shafts 34 and 40 are disposed through the orifices in the lobes of chassis 12 to secure the rotating shafts 34 and 40 to chassis 12, this is not a necessary limitation of this invention, as rotating shaft 34 and/or rotating shaft 40 may be attached to chassis 12 using pins, detents, journals, or any technique known to those skilled in the art.
FIG. 3 shows an example of writing device 46 being inserted in area 44 of hollow rotating shaft 40. FIG. 4 shows writing device 46 secured in rotating shaft 40. Take-up core 48, FIG. 1, is disposed about rotating shaft 40. Knob 45 is attached to rotating shaft 40 and knob 47 is attached to rotating shaft 34. The writing substrate of core of a rolled writing substrate 38 is attached from rotating shaft 34 across writing surface 32 to take-up core 48 about rotating shaft 40 such that rotating shafts 34 and 40, e.g., with knob 45, provides a continuous writing area 50, FIG. 4 on the writing substrate disposed across writing surface 32. FIG. 5 shows an example of a user note taking on continuous writing area 50 with writing device 46. FIG. 6 shows in further detail core of a rolled writing substrate 38, e.g., rolled paper, disposed about rotating shaft 34 (shown in phantom) and the rolled paper being taken up by take-up core 48 about rotating shaft 40 (shown in phantom).
The result is wrist writing apparatus 10 of this invention provides a convenient and easy way for note taking on the continuous writing area. The hollow area in one or both of the rotating shafts or a clip mechanism on the shaft provides a convenient area for storing the writing device. The continuous writing area on the writing surface is located on the ergonomically shaped chassis attached to the wrist of the user to provide for convenient note taking while performing various activities, such as shopping, walking, motorcycle riding, or any type of note taking activity. Wrist writing apparatus 10 can also be used by doctors, nurses, tradesmen, and the like, for convenient note taking. Moreover, when the core of a rolled writing substrate is completely used, it can be removed and stored for recordkeeping. Additionally, preprinted data on the core of a rolled writing substrate 38, e.g., measurements for wood working, directions, and the like can be provided so that the user can take notes directly on the preprinted core of rolled writing substrate.
Wrist writing apparatus 10, FIG. 7, includes attachment device 60 for attaching chassis 12 to the wrist of a user. Attachment device 60 preferably includes flexible band 62 with a loop mechanisms on one surface, e.g., surface 65, and a hook mechanisms on the other surface, e.g., surface 67, such as VELCRO® or similar type materials. Preferably, attachment device 60 is attached to chassis 12 by attaching patch 39, FIG. 6, of pressure sensitive hook mechanisms to chassis 12 with glue, staples, or similar type devices. The hook mechanisms on patch 39 attach to the loop mechanisms on surface 65, FIG. 7 of the flexible band 62 to secure flexible band 62 to chassis 12. Flexible band 62 may also be attached to chassis 12 by staples, glue, tacks or equivalents thereof. In other designs, attachment device 60 may be made of cloth, leather, plastic, neoprene, or any material known to those skilled in the art, and include a hook and eye device (not shown), similar to a conventional belt. FIG. 8, where like parts have been given like numbers, shows an example of wrist writing apparatus 10 of this invention secured to the wrist of a user with attachment device 60.
In one design, core of a rolled writing substrate 38, FIG. 1, is attached to rotating shaft 34 by a plurality of splines 70, FIG. 9, which protrude from rotating shaft 34 to attachably secure core of a rolled writing substrate 38 to shaft 34. In a similar manner, plurality of splines 70 may be used to secure take-up core 48, FIG. 1, to rotating shaft 40.
In one embodiment of this invention, rotating shaft 34 may be secured within orifice 30 by a shelf protruding from the shaft, e.g., shelf 80, FIG. 10, where like parts have been given like numbers, which fits into orifice 30, FIG. 1. Splines 70′, FIG. 10, secure the core of a rolled writing substrate to rotating shaft 34. Similarly, rotating shaft 48, FIG. 1 may include shelf 82, FIG. 10 that fits into orifice 32 and splines 70′ for securing the take-up core to rotating shaft 48.
Rotating shaft 34, FIG. 1, may include clip device 82, FIG. 11, for securing the other end of rotating shaft 34 into orifice 22, FIG. 1. Similarly, rotating shaft 40 may include clip device 82 for securing the other end of rotating shaft 40 into orifice 24. Another example of a clip device that may be used to secure rotating shaft 34 and/or rotating shaft 40 into orifices 22 and 24, respectively, is clip device 82′, FIG. 12.
In one design, rotating shaft 40, FIG. 13, may be hollow and includes tapered portion 84 for securing the writing device in the shaft. Similarly, rotating shaft 34, FIG. 1 may be hollow and may include tapered portion 84, FIG. 13 for securing the writing device in rotating shaft 34.
Although as described above, one or both of rotating shafts 34 and 40 may be hollow for securing writing device 46, this is not a necessary limitation of this invention, as one or both of rotating shafts 34 and 40 may be solid. In this design, clip 91, FIG. 14, e.g., a clevis type clip, is attached to chassis 12 and secures the writing device to the chassis.
In one preferred embodiment, wrist writing apparatus 10′, FIG. 15, where like parts have been given like numbers, includes measuring device 90, e.g., a retractable tape measure, attached to wrist attachment device 60. In one example, a patch 94, FIG. 16, of pressure sensitive hook mechanisms is attached to measuring device 90 with glue or equivalents thereof. The hook mechanism on patch 90 engage the loop mechanisms on surface 65, FIG. 7 of flexible band 62 to attach measuring device 90 to flexible band 62. In other examples, a clip on the back of measuring device 90 (not shown) may be used to attach measuring device 90 to flexible band 62. Measuring device 90 provides for efficient and easy use for carpenters, woodworkers, tradesmen, and the like, to conveniently take measurements. FIG. 17 shows a user employing measurement device 90 to take a measurement and record the measurement on continuous writing area 50 using writing device 46. FIG. 18 shows the user recording the measurement on a continuous writing area 50 and holding tape measure device in place with his thumb.
Thus, wrist writing apparatus 10′ allows the carpenters, woodworkers, tradesmen, and the like, to easily take and record multiple measurements. In operation, the user simply takes a desired measurement, holds the measurement device in place with his thumb (as shown in FIG. 18), removes the writing device from the hollow core of the rotating shaft or the clip on the chassis, records the measurement on the continuous writing area 50, puts the writing device back into the hollow core or clip, and then takes the next measurement. When continuous writing area 50, FIG. 18 is filled with data, knob 45 is rotated so that the core of rolled writing substrate provides additional continuous writing area 50. There is no need to locate and pick up a writing pad or walk back and forth from the location of the measurement. The result is wrist writing apparatus 10′ eliminates multiple steps associated with conventional methods for taking and recording measurements as discussed in the Background section above which saves time and money. In one sample trial, conventional methods for measuring and recording measurements needed to build a cabinet took approximately 8 hours. Using wrist writer apparatus 10′ of this invention, the time required to take and record the measurements for the same cabinet was reduced to approximately 2 hours.
