Windshield wiper blade

A windshield wiper construction having an armature made of relatively rigid plastic comprising a main support element adapted to be connected to an actuator arm, a pair of rocker elements, first coupling means for detachably connecting said rocker elements to the opposite ends of said main support element for rotational movement relative thereto, said rocker arms having a normal position of use in which said arms lie in generally parallel relation to said main support element and being detachable from said main support element when rotated through an angle of about 90.degree., an elongated lodging element mounting a flexible wiper blade, said first coupling means comprising a first body in the form of a stake having two parallel plane walls disposed perpendicularly with respect to the upper surface of said lodging element when in its normal position of use, and a second body having a slit therein terminating inwardly in a cavity of a size to receive said stake, said slit extending generally parallel to the upper surface of said lodging element when said lodging element is in its normal position of use, said slit being of a width to permit said stake to be passed therethrough when said stake is rotated to a position in which its two parallel plane walls parallel the opposite sides of said slit, the width of said slit being insufficient to permit the stake to pass therethrough when the parallel plane walls of said stake do not parallel the opposite sides of said slit, one of said bodies being connected to an end of said main support element and the other of said bodies being connected to the center portion of the rocker element, and second coupling means connecting said lodging element to each of said rocker arms for both limited axial and transverse movement of said lodging element relative to said rocker arms, said second coupling means, by reason of the limited movement of said lodging element relative thereto, permitting limited rotational movement of said rocker arms relative to said main support element but preventing rotational movement of the rocker arms to a position in which they may be detached from said main support element, whereby the wiper will not be accidentally disengaged from its actuator arm during normal use.
