In order to provide a readily detachable sunscreen for any window, including the windshield, of a vehicle such as an airplane, car, or truck, a sheet of perforated mylar, preferably having a reflective coating on its outwardly facing surface, is integrated with a plurality of suction cup assemblies which are employed to attach the sunscreen to the interior surface of the window such that the mylar sheet is disposed closely spaced from and generally parallel to the surface. The suction cup assemblies include integral means for quickly and easily relieving the interior vacuum of the suction cups to permit easy removal of the sunscreen. The short edges of the sunscreen are reinforced with rigid strips to facilitate rolling the removed sunscreen into a convenient generally cylindrical package for temporary storage.

A readily detachable sunscreen for a windshield or other window of a vehicle comprising: A. a sheet of sunscreen material dimensioned and configured to conform to the contour and shape of the window or window portion to be shielded; and B. a plurality of suction cup assemblies fixed to and distributed about said sheet of sunscreen material for engaging and sticking to a surface of the window, thereby supporting said sheet of sunscreen material on the window in generally parallel relationship thereto; C. each of said suction cup assemblies comprising: 1. a flexible bell portion having a concave inner surface and an opening bounded by circumferential lips adapted to conform to and sealingly engage said window surface and therewith define a cavity, said bell portion further having a neck portion extending axially away from the plane defined by said lips, said neck portion having a generally cylindrical axial aperture passing therethrough, said axial aperture comprising: a. a resiliently deformable upper aperture region; b. a lower aperture region coaxial with said upper aperture region; i. said lower aperture region being of larger radius than said upper aperture region and opening into said cavity; and c. a shoulder defined by the junction of said upper and lower aperture regions; 2. a stopper member disposed in said axial aperture and adapted for axial translation between first and second terminal positions; a. said stopper member being dimensioned and downwardly tapered along an upper portion of its length to closely engage and slightly deform said upper aperture region when disposed in said first terminal position to thereby seal off said cavity such that a suction may be maintained in said cavity when said lips sealingly engage said window surface; b. said stopper member having a relieved region along a lower portion of its length providing clearance between said stopper member and said upper aperture region, said lower portion being disposed closer to said opening than said first portion and being dimensioned and configured such that, when said stopper member is in said second terminal position, a communications path is established through said axial aperture to place said cavity at atmospheric pressure, thereby releasing said suction cup assembly from said window surface; and c. said stopper member including a finger projecting outwardly from said lower portion and adapted to engage said shoulder when said stopper member is in said second terminal position, thereby limiting the axial translation of said stopper member and retaining said stopper member in said axial aperture.
