This invention relates generally to eye protection, and more specifically to improvements in structure of eye shade devices.
There is need for disposable, simple, inexpensive eye shade devices, particularly as applicable to the heads of infants so as to extend over the eyes. There is also need to provide improved devices which are easily applied over the eyes and configured to allow eyelid movement despite retention of the device or devices directly over the user's eyes.
It is a major object of the invention to provide an improved, simple, inexpensive eye shade device, or devices, meeting the above needs. Basically, the invention is embodied in eye shade structure that comprises:
a) inner and outer compressible material layers, and a resiliently compressible intermediate layer sandwiched between the inner and outer layers,
b) the layers being flexible and locally compressed to define two re-entrant recesses adapted to be located over the user's eyes,
c) the locally compressed layers defining reduced thickness sections of said layers in registration with such recesses,
d) the inner and outer layers having portions bounding the recesses, and providing cushions to engage user's facial structure bounding the eyes.
It is another object to provide such structure configured to have spectacles shape, and with retention band means attached to the layers at opposite ends of the spectacles so as to extend about the user's head.
A further object is to provide the layers in compressible material form, the intermediate layer consisting of synthetic resinous foam. As will be seen, the inner and outer layers may advantageously comprise brushed NYLON, for skin contact comfort, and the intermediate layer may consist of polyester foam capable of being compressed under heat application to retain compressed composite shape.
Yet another object is to provide the two spaced re-entrant recesses formed by one of said inner and outer layers, and there being two additional re-entrant recesses formed by the other of the inner and outer layers, and in registration with the respective recesses formed by the one layer.
As will be seen, the two recesses formed by the one layer typically face in a first direction, and the recesses formed by the other layer face in a second direction, opposite said first direction. All of the recesses may typically have the same shallow depth. Also, the two reduced thickness sections each have thickness less than one-half the thickness of the layers bounding such recesses.
A further object is to provide retention band means having
The band typically has an anchoring sub-section of increased overall width along band length subtended by said slit. Also, support tab means press-connects an end portion of said band support layer to one of said inner and outer layers.
A further object includes provision of retention tab means attached to said spectacles so as to retain the spectacles to the user's head. The retention tab includes at least one tab compressing a support layer having a tacky surface to adhere to the user's skin, and a carrier layer attached to the support layer and being press-connectible to one of said inner and outer layers.
An added object is to provide spectacles graphics on one of the inner and outer layers, to define graphical rims bounding the recesses.
These and other objects and advantages of the invention, as well as the details of an illustrative embodiment, will be more fully understood from the following specification and drawings, in which:

over the major extents of the structure.
The layers are locally compressed to define two re-entrant recesses 13 and 14 sized and positioned to extend over, or in registration with the user's eyes, as for example an infant's eyes 80 and 81.
An additional forming tool 15′ is typically employed at the opposite side of the structure to press against the layer 12 and at the local zones of recesses 18 and 19. See also the resultant transition thickness zones or cushioning portions 20 and 21 connecting 12 and 12b, looping about the recesses 18 and 19, with beveled slopes as shown. Resultant zone 13 is opposite zone 18; and zone 14 is opposite zone 19. Nose notch 70 is located in the layered composite, between 13 and 14, and between 18 and 19.
As shown, the recesses 13 and 14 formed by thinned layer 11 face in a first direction 30; and the recesses 18 and 19 formed by thinned layer 12 face in the opposite direction 31. Also, all recesses may typically have approximately the same shallow depth “d”.
Further, as an indicator of placement over the eyes, graphics are typically displayed or printed on one of the layers 11 and 12, as for example in spectacles form, as indicated at 35 in
The entire structure between 51 and 52 is preferably a one-piece, resiliently compressible bendable one-piece frame unit.

Also, at 65 and 66, retention or support tab means 70 is provided to press-connect an end portion 71 of the band support layer to one of the inner and outer layers 61 and 63. Two such tabs are shown, to connect opposite ends of the spectacles shape. Tab 70 comprises a support layer 80 and a VELCRO (hook) layer 81 bonded to 80, and adapted to hook connect to the end of the band, at 82, and to hook connect to the fabric of the spectacles unit, at 83. It may be pulled free of either or both connections at 82 and 83, and re-attached, to adjust length.
