Abstract
An eye viewing device with a housing having a center opening containing a magnifying lens and a reflective surface. The housing has outwardly extending hinge flanges. A cover overlies the central opening, and includes an outer abutment surface and an inclined outwardly extending hinge body. The housing hinge flanges and cover hinge body cooperate to provide a hinge joint. The hinge flanges include end portions with hinge contact points which cooperate with a cover contact point to provide a stand for the device when the cover is rotated about the hinge joint until the cover abutment surface and housing underside are in contact.
Claims15
An ophthalmic device comprising:
- a housing having a wall structure that circumscribes a center opening, said center opening containing an image reflective and magnification means;
- a cover overlying said center opening, said cover having an abutment surface;
- a hinge assembly interconnecting said cover and said housing;
- and,
- said hinge assembly providing an axis of rotation between said housing and said cover that is radially and angularly offset from said wall structure;
- and,
- said cover being rotatable from a closed position overlying said center opening to an open position behind said housing until said cover contacts the abutment surface at a predetermined angular orientation.
In a device for viewing magnified images of a user's eye, comprising:
- an enclosure having an enclosure underside and an image-reflecting and magnifying means;
- a cover for said enclosure, having an abutment surface and a cover underside, wherein the improvement comprises:
- a. a hinge assembly that interconnects said cover and said enclosure, said hinge assembly providing an angular rotation of said cover about an axis of rotation by a predetermined amount until said abutment surface of engages said enclosure underside, said hinge assembly including at least one hinge contact point, and said cover underside providing at least one cover contact point to create a support stand for resting the enclosure in an operational position upon an underlying surface.
A method of using an ophthalmic device comprising an enclosure containing image reflecting and magnifying means, and a cover having a cover contact point, said cover overlying the enclosure and being connected to the enclosure by a hinge assembly, said hinge assembly having an axis of rotation and a hinge contact point;
- the method comprising:
- a. while holding the enclosure and cover in a generally horizontal position, grasping the cover and rotating the cover about said axis of rotation by an angular amount of at least about 270°, until a portion of the cover abuts a portion of the enclosure;
- b. rotating the device about 60° to 100° while maintaining the cover in the abutted position of step a.;
- c. placing the device on a selected underlying surface, so that the cover contact point and hinge contact point rest upon the underlying surface;
- and,
- d. while the device rests upon said selected underlying surface, looking into said enclosure and viewing a reflected image.
