EARRING PAD HAVING A DIAPHRAGM FOR VARYING THE PRESSURE EXERTED ON THE EAR Filed Nov. 21, 1955 INVENTOR. KARL SH/L L Y $424M, M9-M A T TORNEYS United States Patent- EARRING PAD HAVING A DIAPHRAGM FOR 'VARYIN G THE PRESSURE EXERTED ON THE EAR Karl Shill, Hayward, Calif.
Application November 21, 1955, Serial No. 548,026
5 Claims. (Cl. 63--14) This invention relates to a device-adapted to be attached to the pressure pad of an earring, and has for one of its objects the provision of inconspicuous means adapted to easily and readily be attached to the pressure pad on an earring to promote the comfort of the wearer and to insure against loss of the earring.
The device of this invention is particularly adapted for use on earrings of the type that have a pressure pad secured on one end of a screw. The screw threadedly extends through the end of one arm of a U-shaped member while the end of the other arm is opposed to the pad. This structure resembles a small clamp. When the pressure pad is positioned at one side of the lobe of the ear and the end of the arm opposed thereto is at the other side of the lobe, the pad will be tightened against the lobe upon rotating the screw carrying the pad.
Earring clamps of the above type very frequently slip off the ear lobe and the earrings are lost or damaged. Also, such clamps are uncomfortable, and with changes in temperatures, the parts of the body including the ear lobes will expand and contract and may become moist or dry, which adds to the discomfort of the wearer as well as contributing to the insecurity of the earring clamps.
With the present invention, the pressure pad is covered and the lobe engaging side is formed and is supported on the pressure pad so as to be yieldable under the expansion and contraction that follows temperature changes, and to be secure on the ear lobe against slippage.
Other objects and advantages will appear in the description and in the drawings.
In the drawings,
Fig. 1 is an enlarged perspective view of an earring with the present invention, partly in cross section, secured on the pressure pad.
Fig. 2 is an enlarged sectional view taken through the device of this invention on a pressure pad, and before any pressure isapplied to the pad.
Fig. 3 is substantially the same as Fig. 2, except that a light pressure ison the device, a portion of the ear lobe being indicated as in engagement with the device.
Fig. 4 is a plan view of the device (reduced size com- .pared with Fig. 2) provided with removable extensions to facilitate securing it on the pressure pad of an earring.
Fig. 5 is a side elevational view of the device shown in Fig. 4.
In detail, the device of this invention comprises an annular element, generally designated 1.
The annular element 1 is formed with a pair of axially outwardly opening recesses 2, 3, in its opposite sides, and a relatively thick flat sided diaphragm 4 positioned closer to the outer side of recess 2 than to the outer side of recess 3 provides a common bottom for said recesses.
The recess 2 is on the side of the device that is adapted to engage the lobe 5 of the ear of the wearer (Fig. 3) while recess 3 is to receive and substantially enclose the adjustable pressure pad 6 of the earring 7.
A screw 8 carries pad 6, and said screw threadedly extends through theouter end of one arm 9 of a U or C clamp, while the other end 10 of said clamp is opposed to the pad.
, Theusual pressure pad 6 of the earring is formed with a convex surface facing theend 10 of the clamp for wearer comfort. However, this results in slippage of the pad on the lobe of the car. If the surface is roughened, the pain to the wearer is not endurable.
' In the device lthe recess 3 is an enlargement within the body of the device, since the opening 12 is relatively small, being only slightly larger than the screw 8.. The maximum diameter of recess 3 is about equal to the diameter of the circular pressure pad 6 and since the ma terial of the, device 1 is elastic, the sides of the opening- 12 will readily stretch sufiiciently to enable 'the pressure pad to enter recess 3'. w
The depth of recess 3 axially of the device 1 is about equal to the maximum .thickness of the pressure pad.
' From their central engaging points the spacing between the pressure pad and the diaphragm is progressively greater in direction radially outwardly of the pad and diaphragm. This combination is quite important, as will be later described.
The annular-rim 14 around recess 2 is of the same internal diameter as the maximum internal diameterot' the recess 3. v 3 I In actual practice, when the lobe 5 of the earis posik tioned between the nm 14 andtheend 10 of the U-clarnp that is opposed to said rim, and when the screw 8 is rotated to tighten to clamp the lobe between the device 1 and the end 10, there will be a yieldable pressure of the outer annular edge of mm 14 against the inner side of the lobe 5.
This is because the diaphragm 4 is yieldable axially at its outer edge where it connects with the rim 14. As the tightening of the device against the ear increases, the soft rim 14 will cause a slight annular indentation in the lobe with the result that the portion of the lobe within the rim 14 will project into recess 2 (Fig. 3). will not slip on the ear lobe under the abo'veconditions,
even when-the ornaments carried by the earring are relatively heavy and when subjected to relatively violent jarring and shaking. v V
The fact that the rim 14 is under yieldable tension (by reason of the connection with the pressure pad through the diaphragm) avoids the discomfiture that would otherwise occur in hot weather or when the ear lobe is heated, and it also avoids loosening of the earring upon contraction of the lobe or earring structure in cold weather or upon such lowering in' the temperature, while the earring is being worn, as would otherwise cause the earring to become'loosened; Y
It is apparent that the device that slips over the pres sure pad 'must be'small and inconspicuous.
fining the sides of the recess 2 when the device is on the ear lobe.
Because the device itself is small, in actual size being approximately one-eighth to three-sixteenths of an inch in outside diameter, it is somewhat ditlicult to manually The device 1 v The draw-f ings somewhat exaggerate the size for clarity. lt is also apparent that there is a" squeegee action ontherim de manipulate in stretching it over the pressure pad and may be easily dropped. To facilitate manually positioning said device on the pad, one or more radially projecting. relatively thin strips 15 may be formedfintegrally with the device extending from one or from opposite sides of thedevice even with the base side having the opening 12 formed therein. Obviously,'a row of devices 1 may be connected by such strips in the manufacture of the devices, and the strips thereafter severed midway between adjacent rings in the row, leaving the projections 15. In any event, the ultimate and preferred form results in each device having strips 15 projecting oppositely outwardly as seen in Figs. 4, 5. These stripsprovide means for bold ing by the fingers of the operator in stretching the sides of the opening 12 over the pressure pad, and should the device he dropped, it will not roll away. After the device is on the pressure pad, the strips are cut oif by a knife or by scissors along lines X--X in Fig. 5.
The material of the device is of relatively soft rubber or of any material having similar characteristics that is impervious to attack by any skin secretions and that is not irritating to the skin.
