Description
Background
1. Field of Invention:
This invention relates generally to note recording devices, specifically to a key chain note card.
2. Prior Art:
A notepad is a stack of paper for receiving written notes. It is desirable to carry a notepad and a pen or pencil to make notes, reminders, etc. However, this is inconvenient because most notepads are too large to be carried in a pocket, and carrying a separate pen or pencil is troublesome. The notepad can get frayed if carried in a pocket. In addition, privacy or secrecy is difficult to maintain, because notes written on the top sheet are open to other's view when the notepad is exposed in public.
Various notepad holders have been proposed to overcome these disadvantages. U.S. Pat. Nos. 1,025,007 to Mieden (1912); 1,487,433 to Beckeft (1924); 1,530,070 to Bovee (1925); and 4,524,871 to Klinger (1985); as well as French patent 1,085,354 to Felsenbourg (1954) show fold-open booklets with a note card mounted onto one side, and one or more pens mounted in clips or slots. The notepads, and any notes written thereon, are normally hidden from view when the notebook is in the closed, storage position. Therefore the booklets must be opened before their notes can be read.
U.S. Pat. No. 5,060,794 to Linnet al. (1991) shows a frame that holds a notepad therein. The frame has an open face so that written notes on the top piece of notepaper are visible, and cannot be protected for privacy. Also the notepad is gradually used and depleted, so that it must be refilled periodically.
U.S. Pat. Nos. 4,518,080 to Ohlson (1985); and 5,038,926 to van der Toom (1991) show card holders or frames that securely surround the edges of a card, so that most of the card is visible. If they are used to hold notepaper, they can hold only a single piece; but if they are used to hold a reusable plastic notepad, the written notes may be inadvertently rubbed off from the exposed top surface of the card.
U.S. Pat. No. 2,226,969 to D'Onofrio (1940) shows a money clip that can be used for holding a notepad. If holds a reusable plastic notepad, the written notes may be inadvertently rubbed off from the exposed top surface of the card. French patent 1,394,243 to Seilinger (1965) shows a key chain pillbox with a sliding cover. If it is used to hold a notepad, the cover must be removed before notes can be written or read.
These and all other prior art notepads or card holders either cannot be read until they are opened, or they leave written notes exposed and subject to accidental erasure. Some use consumable notepads that must be periodically replaced, which are also too thick and heavy to conveniently carry in a pocket. Some notepads include no provision for carrying keys.
Objects and Advantages
Accordingly, several objects and advantages of the invention are to provide an improved note card, a note card which can be easily erased and reused, and a note card which prominently displays notes thereon without having to be opened, but which can also hide the notes from view for security.
Other objects and advantages of the invention are to provide a note card which conveniently stores a pen, which can provide a clear and unmistakable signal for indicating the presence of notes, which protects the notes from accidental erasure or smearing, which can be used to conveniently hold keys, and which is compact and easy to carry.
Additional objects and advantages will become apparent from a study of the following description and the accompanying drawings.
Summary of the Invention
A key chain note card device includes a housing with a slot for slidably receiving a note card with a reusable writing surface, and a brightly colored, opposite surface. The housing includes one transparent side and one opaque side, and a hollow shaft for storing a marking pen. The note card is removed from the housing to receive notes written with the pen. The note card can be reinserted into the housing with either the written surface visible through the transparent side of the housing, so that the notes can be easily read; or it can be reinserted with the colored surface visible through the transparent side, so that the notes are hidden from view for security, but still positively alert the user to the presence of notes.

Operation--Both Embodiments
Both embodiments of the key chain note holder are used in the same way, so that only the first embodiment (FIGS. 1A to 1E) will be described below as an example.
The key chain note holder is normally stored or carried in the condition shown in FIG. 1 C, i.e., pen 21 and note card 13 are both fully inserted into hole 20 and slot 12, respectively. When a user wishes to record notes, pen 21 and card 13 are removed from housing 10, so that pen 13 can be used to write exemplary note 29 on writing surface 13A, as shown in FIG. 1A. After note 29 is written, pen 21 is reinserted into hole 20, and note card 13 is reinserted into slot 12 with writing surface 13A visible through transparent side 17 of housing 10, so that note 29 can be easily read without removing note card 13 therefrom. Alternatively, card 13 can be reinserted into slot 12 with brightly colored, opposite surface 13B visible through transparent side 17 to hide note 29 for privacy, but still positively alert the user to its presence. In either situation, housing 10 protects note 29 from accidental smearing or erasure, but after card 13 is removed from slot 12, it can be easily cleaned with a cloth or tissue paper so that it can be reused.
As shown in FIG. 1A, ring 15 with key 16 can be attached to tab 11 so that the note card device can also be used as a key chain fob.
Conclusion, Ramifications, and Scope
Accordingly the reader will see that I have provided an improved key chain note card. It conveniently stores a pen for writing. It includes a reusable surface for receiving notes, which can be easily erased or wiped off with cloth or tissue paper. It protects written notes from accidental erasure or smearing. It prominently displays written notes so that they can be easily viewed. It can also hide notes from view for security, but still positively alerts the user to their presence so that they will not be forgotten. It can receive a key ring for conveniently holding one or more keys, and it is small enough to carry in a pocket or purse.
Although the above descriptions are specific, they should not be considered as limitations on the scope of the invention, but only as examples of the preferred embodiment. Many additional ramifications and variations are possible within the teachings of the invention. For example, the entire housing can be transparent, and both sides of the note card can be white for receiving notes. The housing can be cylindrical for concentrically receiving a cylindrical note card, which is rotated to display notes through a window on the housing. The housing can also be of other shapes, such as oval or triangular. Two lateral, cylindrical housings can be connected by a rectangular channel, like a film cassette, and a flexible, elongated note card or tape is scrolled from one cylinder to the other for displaying notes through a window on the channel. Instead of a note card slidably positioned under a fixed, transparent window, the housing can be a shallow box for holding a note card, which is covered by a hinged, transparent cover. Instead of being entirely plastic, the note card can be made of cardboard and covered with a sheet of celluloid for erasably receiving ink. The housing can be made of other suitable materials, such as polystyrene, glass, etc., and it can also have different dimensions. Other types of locking devices can be used for securing the note card and the pen in the housing. In lieu of the marking pen with the felt tip, a pencil, chalk, ball point pen, or stylus can be provided, and in lieu of a flat plastic note card, a pad of paper sheets, a slate, a computer marking tablet (with suitable connections to a host computer), or a magic market pad can be used.
Therefore the scope of the invention should not be determined by the examples given, but by the appended claims and their legal equivalents.
