Attorney, Agent or Firm: Weiner, Carrier & Burt, P.C., Carrier; Joseph P., Weiner; Irving M.
A wiper deicing device for a vehicle is disclosed which comprises a mechanism for resiliently impacting the window wiper against the window, including a reciprocatable member operatively engagable with the wiper, and a mechanism for stabilizing movement of the reciprocatable member. The impacting means includes either a manual or powered actuator for cyclically moving the reciprocatable member between extreme positions thereof, corresponding to a position in which the wiper is engaged with the window and a position in which the wiper is disengaged from the window, and will preferably include one of a cam mechanism, a gear mechanism, a crank mechanism and a lever mechanism operatively connected to or engaged with the reciprocatable member. The deicing device also preferably includes a mechanism for limiting pivoting movements of a blade portion of the wiper relative to an arm portion of the wiper for thereby distributing a lifting force of the reciprocatable member across a length of the wiper blade. |

DETAILED DESCRIPTION According to the present invention there is provided a wiper deicing device for a vehicle having a window and a window wiper, comprising means for resiliently impacting the window wiper against the window, including a reciprocatable member operatively engagable with the wiper, and means for stabilizing movement of the reciprocatable member.
The impacting means preferably includes actuating means for moving the reciprocatable member to cyclically disengage the wiper from the window and reengage the wiper with the window, and most preferably includes a powered actuating means which disengages the wiper from the window at a first rate and reengages the wiper with the window at a second, higher rate.
The wiper deicing device according to the invention also preferably includes means for distributing a force of the impacting means across a longitudinal length of the wiper to assure efficient, uniformed removal of ice, as well as a relatively large engagement member provided on either the wiper or the reciprocatable member for facilitating engagement between the wiper and the reciprocatable member.
It is an object of the present invention to provide a wiper deicing device which functions rapidly and efficiently to remove ice from a window wiper so as to assure reliable operation of the wiper and a clear, safe view through the window.
It is another object of the invention to provide such a wiper deicing device which may be conveniently actuated within the passenger compartment of the vehicle, either in a powered manner or through manual actuation.
It is still another object of the invention to provide a wiper deicing device which is durably reliable and does not detrimentally affect normal use of the wipers.
Other objects, advantages and salient features of the invention will become apparent from the following detailed description which, when taken in conjunction with the annexed drawings, discloses preferred embodiments of the invention.
