Eye shields with selectively releasable snap-fit assembly

1. An eye shield, comprising

a frame having a plurality of receivers located along the frame and a plurality of latches located to cooperate with the receivers,

each of the receivers comprising an elongate cavity having an open front with a sloped entrance wall extending upwardly from the open front at an angle, and a catch wall located behind the sloped entrance wall, the catch wall defining a catch surface,

each of the latches comprising a flap hingedly connected to the frame, and a void area formed on the flap as a window to extend though the flap and configured to impart flexion to the flap when pressure is applied to a lower edge of the flap, an elongate catch extending upwardly at an angle from an inner surface of the flap corresponding substantially to the angle of the sloped entrance wall, and a tooth projecting from a distal end of the elongate catch and configured to engaging the catch surface of the catch wall; and

a lens having a plurality of spaced apart lens apertures extending through the lens and located so as to align with the receivers of the frame when the lens is positioned for installation onto the frame;

wherein, the latch is engageable with the receiver by rotating the latch to pass the elongate catch into the receiver through the aligned lens aperture and the open front of the receiver to latchingly engage the tooth with the catch surface of the receiver in a snap-fit frictional relationship, and

wherein the latch is selectively disengageable from the receiver by applying force to a lower edge of the flap and flexing the lower edge of the flap rearward slightly to disengage the tooth from the catch surface.

2. The eye shield of claim 1 , wherein the sloped entrance wall extends upwardly from the open front at an angle of from about 20 degrees to about 40 degrees.

3. The eye shield of claim 1 , wherein the frame is of molded plastic construction and the receivers and the latches are co-formed with the frame.

4. The eye shield of claim 1 , wherein the latch is repeatably engageable and disengageable with the receiver.

5. The eye shield of claim 1 , wherein a bottom of the receiver is open.

6. An eye shield, comprising

a frame having a plurality of receivers located along the frame and a plurality of latches located to cooperate with the receivers,

each of the receivers comprising an elongate cavity having an open front with a sloped entrance wall extending upwardly from the open front at an angle, and a catch wall located behind the sloped entrance wall, the catch wall defining a catch surface,

each of the latches comprising a flap hingedly connected to the frame, and a window formed on and extending though the flap and configured to impart flexion to the flap when pressure is applied to a lower edge of the flap, an elongate catch extending upwardly at an angle from an inner surface of the flap corresponding substantially to the angle of the sloped entrance wall, and a tooth projecting from a distal end of the elongate catch and configured to engaging the catch surface of the catch wall; and

a lens having a plurality of spaced apart lens apertures extending through the lens and located so as to align with the receivers of the frame when the lens is positioned for installation onto the frame;

wherein, the latch is engageable with the receiver by rotating the latch to pass the elongate catch into the receiver through the aligned lens aperture and the open front of the receiver to latchingly engage the tooth with the catch surface of the receiver in a snap-fit frictional relationship, and

wherein the latch is selectively disengageable from the receiver by applying force to a lower edge of the flap and flexing the lower edge of the flap rearward slightly to disengage the tooth from the catch surface.
