Patent Application
20050011981
The invention relates generally to an accessory or identification card holding device. More specifically, it relates to a spring-loaded, retractable accessory or ID card holder worn by the user.
Retractable devices for holding cards, keys and other objects are well known. For instance, several U.S. Patents describe key holding devices. See, for example, Paugh U.S. Pat. No. 5,833,165 and U.S. Pat. No. 6,073,875. Others disclose devices for holding golf-related accessories. See, for example Johnson U.S. Pat. No. 5,230,117, Moultrie U.S. Pat. No. 5,555,589, Jones U.S. Pat. No. 5,815,873, McGee U.S. Pat. No. 5,864,925, and Halloran U.S. Pat. No. 6,112,357. Still others disclose a device for holding a cellular phone, Poulson U.S. Pat. No. 5,938,137 and other accessories Salentine U.S. Pat. No. 5,697,572, Shih U.S. Pat. No. 5,954,288.
Generally, such devices include a housing containing an extendable/retractable circular string, cable or cord, attached to a spring mechanism which loads when the cord is extracted and relaxes when the cord is released, thereby retracting the cord. Typically, a thin round cord is used because this is the simplest geometry for spooling within the housing. The particular accessory, such as an identification or security access card, keys, small tools and the like, is attached to the end of the cable cord. Such devices provide a convenient method for keeping accessories attached to the user even while the accessory is useable at some extended distance.
This technology has been used with personal identification and security access cards. Frequently, companies require employees to always carry their card and the card is used several times during the work day to inform automatic card readers of desired access to secured areas. Typically, the card is attached to a retractable cord. When worn, the card has a tendency to flap and spin about the axis of the cord as the wearer moves about—particularly in a windy environment.
The instant invention relates to an automatically retracting cardholder or accessory holder which, when worn, retains and automatically reestablishes the desired orientation of the card or accessory to user. This is accomplished by using a longitudinally flexible tape with lateral stiffness and some ability to be twisted about the long axis, but with a return memory such that the passive orientation of the face of the card to the tape and housing face is maintianed. Alternatively, a longitudinally flexible cord may be used, with a non-circular cross-sectional geometry having a long and short axis and lateral stiffness. The tape (or cord) passes through an orifice in the housing that geometrically corresponds to the shape of the tape, thereby obviating the tape from passively rotating about its long axis, or, due to the inherent memory of the long axis rotation of the tape, automatically reestablishing the desired orientation of the tape rotation if the tape is twisted by the user. The means for attaching the card or other accessory to the tape is such that the orientation of the accessory to the tape is fixed. Thus, the orientation of the card or accessory to the housing, and consequently the user wearing the housing, is fixed thereby.
It is an object of this invention to provide an automatically retracting card or accessory holder that can be worn by a user.
It is an object of this invention to provide a card holder with an extendible and retractable tape wherein the tape orientation to its housing is fixed about its long axis.
It is an object of this invention to provide a card holder that passively retains and automatically reestablishes the orientation of the card to the wearer of the card holder.
It is an object of this invention to provide a card holder that will allow the user to move the card or accessory by hand as necessary, but will reestablish the preferred orientation upon retraction of the accessory.
It is an object of this invention to provide a card holder that is worn on the side of the user and orients the card flush to the user's side.
In accordance with the above objects and others described herein, a self-orienting retractable ID card holder is provided, comprising a housing with a circular cavity, a broad-faced top and bottom and a side having a tape-orienting slot. A longitudinally flexible and laterally stiff tape is coiled within the cavity and passes through the slot in the side of the housing. The tape has a central end affixed within the housing and a peripheral end external to the housing. The tape has a cross-sectional long and short axis and is dimensioned to pass closely and snugly through the slot. A card holding means which maintains a fixed orientation of the card to the tape is affixed to the peripheral end of the tape. The card holder additionally comprises a coil spring with a first end affixed to the housing and a second end affixed to the tape such that the spring loads when the tape is withdrawn from the housing and dissipates as the tape withdraws into the housing.
Referring to the drawings,
The housing (10) is typically made of a hard plastic, but could be metal. The plane of the broad sides of the top (11) and bottom (12) are referred to herein as the face of the housing. The top (11) and bottom (12) is typically assembled by means of a screw (18) as described. However, other means for assembly, such as a central snap, or peripheral clips are well known in art and are incorporated into other embodiments of the invention.
The coiled spring (30) is made of metal, usually steel or aluminum. For use with identification cards, the retention force is typically less than 0.5 pounds at a two foot extension; however, the force can be increased, if required for heavier accessories, by using a thicker metal for the spring.
The tape (15) is made of plastic, extruded aluminum or other durable material which is longitudinally flexible such that the tape can easily be wound upon the spool (20), and is also laterally stiff and rigid. Furthermore, rotation of the tape (15) about its long axis (41) is resisted and the inherent memory of the tape material is such that, any rotation about the long axis (41) induced by the user during use will automatically be eliminated upon release of the tape. These properties are essential to maintaining the desired fixed orientation of the card or accessory at the end of the tape (40) to the tape (15) and of the tape to the housing (10). Typically the tape is rectangular in cross section., however other shapes can be used in other embodiments. For instance, the tape can be slightly convex or concave, or the tape can be oblong or oval. The essential feature is that the tape is not round and that the tape-orienting slot (14) is contoured to snugly fit the cross-sectional shape of the tape. This feature ensures the fixed relationship of the plane of the tape (15) to the housing (10).
Other means for holding a card are well known. For instance, the male or female portion of a snap can be incorporated into the peripheral end (40) of the tape (15). the complementary portion is incorporated into the card or accessory. Alternatively the card holding means is a rigid J-hook shape that passes through a hole in the card.

In a preferred embodiment, the card holder is designed to be worn on the side of a user, e.g. clipped on the user's belt. Here, the desirable orientation of the card is flush to the user's side, in which case the preferred orientation of the plane of the flat side of the card is in alignment with the face of the tape housing. This can be accomplished in several ways.
Other variations of material, manufacture and assembly are common in the art and are incorporated herein to other embodiments of the invention.
