HAND IMPLEMENT PARTICULARLY USEFUL FOR REMOVING INFLATION TIRE CAPS
FIELD AND BACKGROUND OF THE INVENTION The present invention relates to hand implements, and particularly to a hand implement which is useful for removing and reapplying the caps on inflation valves in inflatable tires.
The inflation valves in inflatable tires on road vehicles are commonly covered with caps which must be removed in order to check the pressure of the inflated tire and to increase or decrease the air pressure within the tire. Since such inflation tire caps are exposed to the road conditions, they are generally covered with dirt which soils the user's hands when removing or reapplying the caps. In addition, such caps are frequently located such as to make their accessibility inconvenient or awkward to the user.
OBJECT AND BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a hand implement particularly useful for removing inflation tire caps so as to avoid soiling the user's hands and also the awkwardness sometimes involved when removing or reapplying inflation tire caps.
According to the present invention, there is provided a hand implement particularly useful for removing and reapplying caps on inflation valves in inflatable tires, comprising: a body member formed with a socket section at one end dimensioned to receive a cap on an inflation valve, and with a finger-gripping section at the opposite end for manually gripping the implement while applying it to the cap on an inflation valve and for manually rotating the implement, after having been applied to the cap, for removing it from the inflation valve or for reapplying it to the inflation valve; said body member being further formed with a bore extending from said socket section at said one
end through said opposite end to enable an elongated element to be inserted therethrough for dislodging a tire cap from said socket section should one become lodged in said socket section.
According to further features in the described preferred embodiments, the socket section has an inner surface of conical configuration increasing in diameter towards its outer end to enable it to receive caps of different dimensions.
One preferred embodiment is described wherein the finger-gripping section includes an outer annular skirt integrally joined to the body member. The annular skirt is of conical configuration, being of smallest outer diameter at the end of the body member opposite to the socket section, and increasing in diameter towards the opposite end of the annular skirt. The smallest diameter end of the annular skirt is joined directly to the outer surface of the body member; and the larger diameter end of the annular skirt is joined to the outer surface of the body member by means of a plurality of axially-extending circumferentially-spaced ribs.
A second preferred embodiment is described wherein the finger-gripping section is integrally formed with longitudinally-extending ribs on its outer surface. The ribs are formed with an angular twist with respect to the longitudinal axis of the implement, and increase in height from the socket section to the opposite end of the implement .
As will be described more particularly below, a hand implement constructed in accordance with the foregoing features may be used in a very simple and convenient manner for removing caps on inflation valves whenever it is desired to check, increase, or decrease the tire pressure, without soiling the hands of the user. The implement is useable with tire caps of different sizes; and should a tire cap become lodged in the socket section of the implement, it can be
easily dislodged by merely inserting an elongated element, such as a long key or a screw driver, through the open end of the implement. Moreover, such an implement can be constructed in volume and at low cost.
According to a still further optional feature of the invention, the finger-gripping section of the body member may further include a loop for attaching the implement to a key ring, thereby facilitating carrying the implement as well as better assuring its availability whenever desired to be used.
Further features and advantages of the invention will be apparent from the description below.

DESCRIPTION OF PREFERRED EMBODIMENTS
The hand implement illustrated in Figs. 1-3 of the drawings is particularly useful for removing and reapplying caps on inflation valves in inflatable tires. It includes a body member 2 formed with a socket section 3 at one end to receive a cap on an inflation valve. Body member 2 is further formed with a finger-gripping section 4 at the opposite end for manually gripping the implement while applying it to the cap on an inflated tire and for manually rotating the implement in order to remove or reapply the cap. As shown particularly in Fig. 3, body member 2 is of a one-piece, hollow, tubular construction, integrally formed with the socket section 3 and the finger-gripping section 4 at its opposite ends, and having a bore 5 extending from its socket section 3 through the finger-gripping section 4.
As also seen in Fig. 3, the outer surface of body member 2 is of conical configuration, increasing in diameter from the socket section 3 through the finger-gripping section 4. The inner surface of body member 2 defined by bore 5 also increases in diameter from the socket section 3 throught he finger-gripping section 4. However, the inner surface of the socket section 3 is of conical configuration which increases in diameter towards the outer end of that section, to enable the socket section 3 to receive caps of slightly different dimensions, and also to releasably retain the cap therein until it is reapplied to the inflation valve.
As further seen in Fig. 3, the inner surface of socket section 3 is formed with a plurality of axially-extending, circumferentially-spaced ribs 6 for gripping a cap when received in that section.
The finger-gripping section 4 of the implement is of larger outer diameter than the socket section 3. This facilitates manually gripping section 4 between the fingers and rotating the implement in order to remove or reapply a cap when received within the socket section 3. For this
purpose, the finger-gripping section 4 is provided with an annular skirt 7 of generally conical configuration, being of smallest diameter at the end of body member 2 opposite to the socket section 3, and increasing in diameter towards the opposite end of the annular skirt.
The smaller diameter end 7a of annular skirt 7 is integrally joined to the outer surface of the body member 2, whereas the larger diameter end 7b of annular skirt 7 is joined to the outer surface of body member 2 by means of a plurality of axially-extending ribs 8 which are circumferentially-spaced around the body member. In addition, the outer surface of the annular skirt 7 is formed with a plurality of flat surfaces 9 extending axially from the large-diameter end 7b of the annular skirt and spaced circumferentially around the annular skirt. These flat surfaces 9 define a generally polygonal outer surface for gripping by the user's fingers and facilitate gripping and rotating the implement during use.
It will be seen that the implement illustrated in Figs. 1-3 of the drawings may be conveniently used to remove and/or reapply a cap (not shown) to an inflation valve in an inflatable tire in order to check, increase, or decrease, the tire pressure. This may be conveniently done by gripping section 4 of the implement, applying section 3 over the cap, and then rotating the implement, all of which can be accomplished in a convenient manner without coming into hand-contact with the cap which might tend to soil the user's fingers. Should a tire cap become lodged within socket section 6, it may be conveniently dislodged by merely inserting an elongated element, such as a long key or a screw driver, through the open end of bore 5 and pushing the cap outwardly of the socket.
Fig. 4 illustrates the implement of Figs. 1-3 but provided with a loop 10 for attaching the implement to a key ring or the like in order to make the implement conveniently accessible when and as needed.
Figs. 5-7 illustrate an implement similar to that in Figs. 1-3, in that it also includes a body member 20 formed with a socket section 21 at one end to receive a cap on an inflation valve, and further formed with a finger-gripping section 22 at the opposite end for manually gripping and rotating the implement in order to remove or reapply the cap. Body member 20 is also of a one-piece hollow, tubular construction, integrally formed with socket section 21 and finger-gripping section 22 at its opposite ends, and with bore 23 extending continuously from socket section 21 through the opposite end of the implement.
As shown particularly in Fig. 6, the inner surface of socket section 21 is of conical configuration, increasing in diameter towards the outer end of that section. Such a construction enables the socket section 21 to receive caps of slightly different dimensions, and also to releasably retain a cap when received therein.
As further seen in Fig. 6 and also in Fig. 5, the socket section 21 is formed with a plurality of axially-extending circumferencially-spaced ribs 24 for gripping the cap when received in that section.
The outer surface of finger-gripping section 22 of the implement illustrated in Figs. 5-7 is integrally formed with a plurality of longitudinally-extending ribs 25 which have an angular twist with respect to the longitudinal axis of the implement, and which increase in height from the socket section 21 to the opposite end of the implement. The outer surface of the socket section 21 is flattened and unribbed to define an outer surface of generally polygonal configuration .
Both of the above-described implements can be produced in volume and at low cost, e.g., by injection molding using any suitable plastic. Each implement can accommodate different size caps, permits convenient removal of a cap from the tire and from the implement itself, and can be conveniently carried so as to be readily accessible
whenever desired, e.g., by providing a loop 10 (Fig. 4) attachable to a key ring.
While the invention has been described with respect to two preferred embodiments, it will be appreciated that these are set forth merely for purposes of example, and that many variations may be made. Also, the implement can be used for removing or reapplying other devices, such as screws or nuts, in a convenient manner.
