Multiple Utility Device for a Key Ring

1. Field of the Invention

The present invention relates to key rings (including key chains and the like), and more particularly to a utility device for primary use in connection with a key ring. Still more particularly, the present invention relates to a utility device which serves, inter alia, as an anchor for a key ring, a bottle cap opener, a screw driver and a hook for holding itself and for holding other items, such as a lady's purse, with respect to another object.

2. Description of the Prior Art

In the prior art there are many items that serve in the capacity of a key ring. Most of these items are simply display devices which serve an emblematic purpose, such as to identify a vacation spot or a car name plate. These devices serve no other purpose than to provide anchorage for the key ring so that the keys may be more easily found and used. Those devices which serve another purpose besides anchorage, such as a match holder or a whistle, generally have a specfic, limited utility.

Accordingly what is needed in the art is a device for connection with a key ring which has multiple utilities.

The present invention is a utility device for a key ring which serves a plurality of utilities, including key ring anchorage, bottle cap opener, screw driver, hook and item holder with respect to another object.

The present invention is a utility device having a generally C-shaped structure having a central open space defined by interior walls of a main member, two cross members and two opposed tabs. A hole is provided in the C-shaped structure to permit a key ring (key chain and the like) to be connected thereto. The distance between facing ends of the tabs is preselected to permit the ends to cooperate so that a user can leverably act on a bottle cap to open a capped bottle. One external corner of the C-shaped structure is preferred to be provided with a flat, beveled blade edge to serve as a screwdriver blade. It is further preferred for a portion of the interior walls to have a predetermined contour which serves to assist hooking of the C-shaped structure onto an object. In this regard, a second object, such as a purse, may now, in turn, be hooked to the C-shaped structure to thereby suspend it from the first object.

Accordingly, it is an object of the present invention to provide a utility device for a key ring which provides anchorage for one or more keys attached to the key ring.

It is an additional object of the present invention to provide a utility device for a key ring which is of a C-shape that permits it to be hooked easily onto an object.

It is another object of the present invention to provide a utility device for a key ring which may be hooked onto a first object with a second object, in turn, being hooked onto the utility device.

It is a further object of the present invention to provide a utility device for a key ring which is able to open capped bottles.

It is yet a further object of the present invention to provide a utility device for a key ring which is able to turn screwdriver slotted screws, bolts and the like.

It is still another object of the present invention to provide a utility device for a key ring having a C-shape which has a central opening that includes inside wall portions that are contoured to facilitate hooking the utility device onto a first object while holding a second object thereto.

These, and additional objects, advantages, features and benefits of the present invention will become apparent from the following specification.

Referring now to the Drawing, FIG. 1 shows the utility device 10 according to the present invention in operation with respect to a key ring 12 and a set of keys 14 which are trapped on the key ring. The utility device 10 serves in the capacity of an anchor for the key ring 12 so that the keys 14 are easily found in the pocket or purse of the user.

As can be understood by reference now being directed to FIGS. 2 and 3, the utility device 10 is of a general C-shape composed of an upper cross member 22 and a lower cross member 24 that are each integrally connected with a main member 20 at right angles with respect thereto, an upper tab 18a that is integrally connected with the upper cross member 22 at a right angle with respect thereto, and a lower tab 18b that is integrally connected with lower cross member 24 at a right angle with respect thereto. The general C-shape of the utility device 10 forms a central open space 16 which opens outwardly between the two mutually opposed upper and lower tabs 18a and 18b, having, respectively, mutually facing ends 18a' and 18b'. It is preferred for the utility device to be constructed of a single piece of durable plastic, such as polystyrene, or metal (as shown in the Drawing), such as aluminum or stainless steel. In the case of plastic construction, injection molding is preferred, while in the case of metal construction, a blanking operation is preferred.

By way of example, dimensions of the utility device 10 may be generally as follows. Length of the main member 20 is preferred to be 2.35 inches; length of the upper and lower cross members 22, 24 is preferred to be 1.41 inches; and the length of the opening between the ends 18a' and 18b' is preferred to be 0.91 inches. Width for each of the main member, upper and lower cross members and upper and lower tabs is preferred to be on the order of about one-half inch, but this may vary, especially with respect to the upper and lower tabs. In the case of plastic construction, a thickness for the utility device 10 on the order of 0.25 inches is preferred, while in the case of metallic construction, a thickness on the order of 0.09 to 0.125 inches is preferred, depending on composition of the metal.

A hole 26 is provided in the utility device 10 at a location preferably adjacent lower tab 18b, near a corner 28. The hole 26 serves to allow a key ring (key chain and the like) 12 to be connected with respect to the utility device 10.

A corner 30 of the utility device 10 is provided with a locally flat, beveled blade edge 32 of the type used in a conventional screwdriver. As can be discerned by reference to FIG. 9, this blade edge 32 is structured to interface with a screwdriver slot 34 so that, for example, a screw 36 can be turned with respect to a workpiece (such as a wooden block 38) in a manner similar to that made possible by of a conventional screwdriver. It is preferred that the corner 30 having the blade edge 32 be located diagonally opposite the corner 28 that is located adjacent the hole 26, although this is not a requirement. FIG. 8 shows how the blade edge 32 may also serve to lift a can tab 40 by inserting the blade edge between the can tab and the can top 42 so that the user may thereupon lift the can tab in order to thereafter open the can top.

The distance between the ends 18a' and 18b' is preselected so that they may cooperate in order to permit a user to open a capped bottle. This structural relationship to function is exemplified in FIG. 7. It will be seen that in operation one end 18b' is located just under the rim 44 of a bottle cap 46, while the other end 18a' is located at the top 48 of the bottle cap remote from the rim 44 that is adjacent end 18b'. An upward pressure by the user's fingers 50 on the lower cross member 24 and downward push by the user's thumb 52 on upper cross member 22 results in a lever action in which the bottle cap 46 is dislodged from the bottle 54 due to the forces transmitted via the ends 18a' and 18b' to the bottle cap. With regard to plastic construction of the utility device 10, it is preferred for the ends 18a' and 18b' to be wedge shaped so as to facilitate the above described operation with respect to dislodging the bottle cap.

Still a further utility of the utility device 10 is to serve as a hook for hooking onto an object and, further, for hooking yet another object onto itself. FIGS. 4 through 6 depict this utility.

As can be discerned by reference to FIG. 2, it will be seen that the inside wall 22' of the upper cross member 22 is at least in part provided with first and second concavely shaped indentations 56, 58 positioned on either side of a central ridge 60. The first concavely shaped indentation 56 may also be partly located in the inside wall 20' of the main member 20, and the second concavely shaped indentation 58 may be partly located in the inside wall 18a" of the upper tab 18a. Each of the concavely shaped indentations 56, 58 serve to facilitate hooking of the utility device 10 onto an object. For instance, FIGS. 4 and 5 show this operatively with respect to objects in the form of a belt loop 62, and a fixture 64 (in this case a bathroom tissue dispenser). It will be noted that the object tends to nestle with respect to at least one of the concavely shaped indentations to securely hook the utility device 10 with respect to the object. Further, a third concavely shaped indentation 66 is preferred to be at least in part provided in the inside wall 18b" of the tab 18b located adjacent lower cross memeber 24. The third concavely shaped indentation may also be partly located in the inside wall 24' of the lower cross member 24. As depicted in FIGS. 5 and 6 the concavely shaped indentations 56, 58 and 66 serve as an aid to hold not only the utility device to a first object, such as a fixture 64, but also to hold a second object, such as a purse 68 via its straps. Thusly, the utility device 10 serves to releaseably connect a second object (such as a purse 68) to a first object (such as a fixture 64 or a rail 70). With respect to plastic construction of the utility device 10, the aforementioned preferred wedge shaped ends 18a' and 18b' facilitate hooking of the utility device to an object.

In any mode of operation of the utility device 10, a key ring with or without keys may be connected to the utility device via the hole 26.

To those skilled in the art to which this invention appertains, the above described preferred embodiment may be subject to change or modification. Such change or modification can be carried out without departing from the scope of the invention, which is intended to be limited only by the scope of the appended claims.
