BACKGROUND OF THE INVENTION1. Field of the Invention[0001]
The present invention relates to card holders that typically hold identification cards or access cards and often are connected to a display device and attached to a person or a persons clothing.[0002]
2. Description of the Related Art[0003]
Wearable card holders are common for displaying identification badges, access cards, and other credentials in offices, hospitals, conventions, and other situations. Card holders function as a means to attach cards to a user's clothing while displaying the cards. The card holder may also be attached to a person such as by way of a neck lanyard or wristband. Card holders are available in a variety of shapes, designs, and materials.[0004]
The sizes of card holders have become increasingly standardized as the size of identification cards have become standardized to the approximate size of a credit card or driver's license. Often these cards have pictures, logos, writing, and other graphics to be displayed by the user. Some cards are machine-readable and include devices such as magnetic stripes, bar codes, and electronic circuits. Frequently such cards are used to gain entry to certain areas by inserting them into a machine, showing them to a security guard, or placing them near a sensor.[0005]
Card holders, therefore must allow users to repeatedly access their cards. Typically the card is completely encapsulated by the card holder. Many card holders utilize envelope designs to secure a card. Some of the envelope designs include snap closures or tab closures. Such designs are effective for preventing accidental loss of cards, but they require additional efforts to remove the cards from the holders. While a card is completely encapsulated, it typically cannot function with reader devices while being held in these types of holders and thus must be removed from the holder to be used. For this reason, these types of card holders are not preferred for cards which include embedded information-containing indicia such as magnetic stripes, bar codes, or electronic circuits.[0006]
As an alternative to card holders, holes or slots are punched into cards and clips are attached through them. Punching holes in cards is not favorable because holes will often interfere with embedded indicia and with the overall appearance of the card. Punching the holes also requires additional machinery and labor. Furthermore, a hole in the card will frequently cause weakening or wearing of a card, requiring replacement sooner than a card without a hole.[0007]
Notwithstanding the many different types of card holders, it is believed that there is a need for an improved card holder that allows users quick and easy access to embedded indicia and does not obscure the appearance of the card.[0008]
SUMMARY OF THE INVENTIONIn accordance with one aspect of the present invention, a card holder is provided that secures cards in such a way that a portion of the card protrudes from the holder while the card is fully inserted. This allows cards to be secured without being completely encapsulated. Where appropriate, the exposed portion of cards inserted in this card holder can be made to communicate with reading devices such as card readers or card-operated door locks. The card holder may be provided with a tab for connecting the holder to the cord of a displaying device such as a retractable reel. This enables the cord to be conveniently placed near a sensing device without separating the holder from the cord.[0009]
In accordance with another aspect of the present invention, a card holder is provided that allows indicia on cards to be visible through the card holder. The card holder is made of a clear plastic and does not block or distort the appearance of the card.[0010]
In accordance with another aspect of the present invention, a card holder is provided that secures a card with a three sided space. The dimensions of the space are such that cards fit snugly into the card holder. The cards are held securely due, in part, to the tight fit without a need for glue. This configuration allows the cards to be removed from the holder when desired.[0011]
In accordance with another aspect of the present invention, a card holder is provided that secures cards with a tacky adhesion of the plastic holder to the card. The properties of the plastic used in the card holder provide some adhesion to plastic cards to prevent accidental dislodgment but allow for removal from the holder when desired.[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTFIG. 1 illustrates a[0020]card holder10 preferably made from transparent, flexible plastic. FIG. 2 shows that the card holder includes apocket12 defined by twoplastic walls14 and16 lying in face-to-face relationship with each other. The walls are sealed along theirshort ends22 and23, and also along onelong edge20, with the oppositelong edges19 and21 being unsealed, to define an entry to the pocket. Thewall16 and itsedge19 extend beyond thewall14 to facilitate opening of the pocket and insertion of astiff card18. The length of the holder is such that holder ends tightly engage the card ends. While a holder with only two opposite ends of the pocket sealed might grip a card sufficiently, it is preferred that three edges of the walls are sealed so as to limit the extent to which a card can be inserted into the pocket holder.
The cross section in FIG. 3 illustrates that the card holder is flat when no card is inserted. When a card is inserted, the card holder walls must spread to receive it as shown in FIG. 4, which causes the card holder's length to shorten slightly, tightening the grip on the card.[0021]
In a preferred embodiment, the pocket is sized to fit a standard size,[0022]plastic identification card18 with dimensions of about 2⅛ inches by 3⅜ inches. The dimensions of the pocket are matched to the card to provide a snug fit. The actual dimensions of the card holder can be varied before manufacture in anticipation of different sized cards. In a preferred embodiment, the pocket is approximately 3⅜ inches by 1 inch. The thickness of the plastic is preferably approximately {fraction (2/100)} inches.
The preferred embodiment of the holder has a ratio of approximately three to one for the length of the[0023]edges20 of the pocket to that of the twoshort edges22 and23. This configuration provides that a portion of a card, the exposedportion24, will remain uncovered when the card is fully inserted into the holder. With the typical card, the exposed portion is about 1⅛ inch by 3⅜ inch.
As may be appreciated from FIGS. 5 and 7 the part of the card remaining uncovered may contain a[0024]magnetic stripe26, a circuit, or other indicia. Because it remains uncovered, the indicia may interact with a sensing device. For example, FIG. 7 shows that a card with a computer readable magnetic stripe may be properly swiped through areading device37 without removing the card from the holder. Because reading devices are available in a variety of configurations and some require cards to be inserted further than others, in the preferred embodiment more than half of the card remains uncovered.
FIG. 1 illustrates a[0025]tab28 connected to one of theshorter edges23 of the card holder. In the preferred embodiment, the tab has ahole30 to facilitate attachment to a displaying device. For example, FIG. 1 shows the hole in the tab sized to accept aclip34 which is used to attach the card holder to acord35 of aretractable reel36, with the reel being attachable to a user's clothing or belt. The holder and card may remain attached to a person for the entire time the card is being used. Other display devices such as aneck lanyard40 shown in FIG. 6, or a wristband, can also be attached to the holder. When attached to one of these devices, the holder can be released from a quick releasingbuckle42 for use with a sensing device and then returned to the buckle.
Several types of plastic can be used to make the card holder, but the preferred material is a soft, somewhat elastic or stretchy vinyl. Sufficient plasticizer is added to the vinyl to obtain the desired softness. Preferably the material is in the 1S to 6S hand softness range, with the most preferable softness being 3S. FIG. 5 shows that the vinyl used in the preferred embodiment has a tackiness to it that provides some[0026]adhesion38 to inserted cards. This adhesion is known in the industry as blocking.
As seen in FIGS. 1, 5 and[0027]6 the transparent plastic used in the preferred embodiment does not interfere with the visual appearance of indicia on a card.
The card holder can be made in a single operation wherein three sides of the pocket are joined, as well as the periphery of the[0028]hole30 and thetab28. The plastic may be joined by RF energy or other suitable means.
While it has been found that having a card gripped by the holder simply with the dimensions and characteristics of the material, other techniques may be employed for securing the card to the holder. For example, small quantity of sticky material could be provided in the card pocket that would releasably hold the card. With that technique, the plastic or other holder material need not be soft and stretchy.[0029]
