Abstract
Abstract of the Disclosure An adaptor is provided for valve stems on vehicle tires which will accept quick connect and disconnect connec-tors. The adaptor is equally functional with quick connect connectors of different sizes and provides a protective cover-ing for the entrance to the valve stem which is quickly re-moved when the connector is to be affixed.
Description
lMR 3048.2.
This invention relates to adaptors for valve stems on vehicle tires and particularly to such valve stems on truck tires, especially for multi wheeled vehicles.
It is well known that proper inflation of tires on vehicles i5 an important factor not only in the operation thereof but in decreasing the cost of maintenance and repair.
This factor is particularly important with commercial vehicles ~uch as trucks, yet with multi wheeled units is frequently neglected because of the time and trouble necessary for the proper maintenance of air pressure.
The structure of my U. S. patent 3,gl3,632 is of great assistance in overcoming the reluctance of truck opera-tors to adequately maintain their vehicles by making such main-tenance less troublesome and time consuming. On the other hand the invention of the present application speeds up ~uch check-ing of air pressure in vehicle tires, particularly truck tires and also can provide warning of a leaky valve core.
Among the objects of the present invention are the provi~ion of an adaptor suitable for use with the valve stem on a vehicle tire without alteration in the structure of the valve stem itself; the provision of such a unit which coopera-tes with a standard quick connect and disconnect coupling to connect an air source to the vehicle tire; the provision of such an adaptor which functions effectively with different siz-ed quick connect couplers; and the provision of such an adaptor which is inexpensive to manufacture and effective in operation.
Other objects and features will be in part apparent and in part pointed out hereinafter.

In Fig. 1 an adaptor 10 of the present invention is shown threaded on to a valve stem 12 of a truck tire (not shown). Adaptor 10 consists of a body 14 and a cap 16 con-nected by a flexible strap 18. Body 14 contains a valve core 20 which extends from the valve core in valve stem 12 to the end 22 of the adaptor. Valve core 20 is of the usual construc-tion and function~ in the same manner as the valve core in valve stem 12. Valve core 20 is located to contact and depress the valve core in valve stem 12 when valve core 20 is moved to the left in Figs. 1 and 2.
Body 14 is formed with a groove 24 and a groove 26 intermediate the body in order to accept and accommodate quick connect and disconnect couplers. Such a connector i~ shown in Figs. 4 and 5. In Fig. 4 a quick connect coupler 28 having a stop 30 is shown in juxtaposition to adaptor 10 with stop 30 engaging groove 24. Stop 30 and groove 24 hold the connector in place on adaptor 10 until it is removed.
In Fig. 4 a smaller quick connect and disconnect coupler 34 is shown attached to adaptor 10 by means of stop 32.
Stop 32 and groove 26 hold the connector in place on adaptor 10 until it is removed.
As shown in Fig. 4, the quick connect connector should include a valve depressant 36 consisting of a plate 38 on which is mounted a finger 40. A spring 42 presses plate 38 and finger 40 forward to depress valve core 20 to admit air to lMR 3048.2.1 11'38tj3~:
to the tire through adaptor 10 and the valve stem of the tire when the connector is in place. As stated previously, move- -ment of valve core 20 to the left in Figs. 1 and 2 depresses the valve core in valve stem 12. This opens a path for the air into the tire. When connector 28 is removed from adaptor 10 spring 42 moves plate 38 toward the left as shown in Fig.
4 to ~eat it in circular area 44 against 0 ring 46 to shut off the flow of air from connector 28.
To advantageously position the connector 28 or 34 to engage a connector 10 on an outside truck tire it is at times preferable to form the end of the air conduit ~see ~ig. 6) in the form of a 180 angle bend 50 to po~ition the quick connect coupling for attachment to the adaptor. On such outside tires the valve stem and conse~uently the adaptor 10 affixed thereto face to the inside. The 180 angle bend 50 enables ea3y at-achm~nt of the connector in such instances.
Cap 16 i8 preferably con3tructed with a depressant po~t 36 which pro~ects into the body of the cap to meet valve core 20. When depressant 36 ~s pressed the consequent move-ment of valve core 20 releases air into the cavity 38 of cap16 to blow the cap away from end 22. This not only permits ready acce~s to adaptor 10 in order to affix a quick connect coupler thereto but also provideq a warning of a leaky valve core if it i5 found dislodged before depressant 36 is actuated.
For many uses it is preferable to attach the valve stem adaptor of the present invention relatively permanently to the valve stem to avoid among other things lea~age of air from the tire, loss or misplacement of the adaptor or theft of lMR 3048.2.1 lU893'1;~
the adaptor from the valve stem. In this instance the adaptor 60 is constructed as before except that the valve core 62 in the adaptor need only be positioned so that it extends to a location adjacent the end 64 of the adaptor which is remote the valve stem. It need not, however, extend through the length of the adaptor to cooperate with a valve core in valve stem 12 because the valve core in valve stem 12 is omitted.
In this embodiment adaptor 60 is just prior to its threading onto valve stem 12, coated internally on its threads 66 with an adhesive which will form an air tight and pre~sure tight seal when the adaptor 60 is threaded onto valve stem 12.
Suitable adhesives for this purpose are those sold commercial- -16 as Eastman 910 and Loctite 272.
In addition to the foregoing changes when the adapt- -or is to be attached relatively permanently to a valve stem the grooves 68 and 70 for attachment of a quick connect and disconnect coupler need not be as deeply indented into the body of adaptor 60 as grooves 24 and 26 in the Fig. 1 embodi-ment.
Where the structure of the adaptor shown in Figs. 7-10 is employed improved reliability of the combination is se-cured since the adaptor in effect becomes an integral portion of the valve stem so that dislodgement is avoided and leakage -of air obviated. In addition the adaptor is not likely to be removed and lost, stolen or become otherwise disassociated from the valve stem.
From the foregoinq it is clear that the adaptor of the present invention accommodates both small and large chucks lMR 3048.2.1 1~8.~:~34'~
which form part of quick connect couplers, protects the open-ing of the adaptor from entry of dirt or other debris between operations and also functions as a warning of faulty valve cores. The cap is easily removed when the tire is to be in-flated or its pressure is to be checked or adjusted. In addi-tion the adaptor can be relatively permanently attached to a valve stem so that it becomes an integral portion of the valve stem.
The adaptor of the present invention can be used with the valve stem of a vehicle tire without altering the valve stem. If preferred, however, the construction of the ~alve stem may be altered to incorporate the adaptor structure.
The simplicity of operation of tire pres~ure check-ing and adjustment resulting from use of the construction de-scribed render~ the whole operation less burdensome and time consuming so that the vehicle operator is le~s likely to dis-regard the check and resulting wear and repairs are either eliminated or greatly reduced.
Particularly when utilized with the structure of my U. S. patent 3,913,632, air pressure maintenance for multi wheeled vehicle~ is greatly facilitated and i~ accordingly more likely to be performed as directed by owners rather than shirked by operators.
In view of the above, it will be seen that the sev-eral objects of the invention are achieved and other advanta-geous results attained.
As various changes co~ld be made in the above con-structions without departin~ from the scope of the invention t lMR 3048.2 .1 34'~ -it is intended that all matter contained in the above descrip-tion or shown in the accompanying drawings shall be interpret-ed as illustrative and not in a limiting sense.
