Abstract
Abstract A hand held tool with a guide element and a resilient, transparent plate proximate thereto to aid in stripping the protective backing from the adhesive coated side of a pressure sensitive tape and in subsequently applying it to a suitable display surface. The guide element controls the separation of the backing from the tape and is positioned so that the side thereof lacking adhesive coating comes into contact with the plate even as the leading edge of the tape is being pulled away from its backing. Electrostatic attraction between the tape and the plate prevents the tape from sliding therefrom as the plate is first inverted and then moved about to preposition the tape. Tiny feet protruding from the plate hold the tape out of contact with the surface to which it is to be affixed until the user, viewing it through the transparent plate, presses the plate against the display surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
280 words
A tool to aid in applying a film, one side of the film being coated with a pressure sensitive adhesive and protected, initially, by a removable backing, in overlying adhering relationship to a display surface, comprising: (a) a guide element having an aperture and a through passageway with forward and rearward branches which extend generally laterally in opposite directions from the aperture and which communicate therewith, the aperture being adapted to receive a section of the film which has been stripped of its backing and the forward branch being adapted to receive a section of the backing which has been separated from the film; (b) a support member which extends generally laterally from an outer edge of the aperture and which overhangs an entrance to the rearward branch, the entrance being distal from said outer edge of the aperture, the support member having a transparent region projecting beyond at least one wall of the rearward branch a distance substantially greater than the length of the through passageway, so that a leading portion of the side of said film lacking adhesive coating can be guided onto said transparent region with the side of said portion which is coated with the adhesive being directed away from said region; and (c) means connected to the support member for holding the adhesive coated side of said portion out of contact with the display surface when the film, clinging to said region because of an electrostatic charge spontaneously generated on the film when its backing is removed, is interposed between said region and the display surface, so that premature contact therewith is prevented and the film can be prepositioned with respect to the display surface.
Claim 2
Dependent Claim
280 words
A tool to aid in applying a film, one side of the film being coated with a pressure sensitive adhesive and protected, initially, by a removable backing, in overlying adhering relationship to a display surface, comprising: (a) a guide element having an aperture and a through passageway with forward and rearward branches which extend generally laterally in opposite directions from the aperture and which communicate therewith, the aperture being adapted to receive a section of the film which has been stripped of its backing and the forward branch being adapted to receive a section of the backing which has been separated from the film; (b) a support member which extends generally laterally from an outer edge of the aperture and which overhangs an entrance to the rearward branch, the entrance being distal from said outer edge of the aperture, the support member having a transparent region projecting beyond at least one wall of the rearward branch a distance substantially greater than the length of the through passageway, so that a leading portion of the side of said film lacking adhesive coating can be guided onto said transparent region with the side of said portion which is coated with the adhesive being directed away from said region; and (c) means connected to the support member for holding the adhesive coated side of said portion out of contact with the display surface when the film, clinging to said region because of an electrostatic charge spontaneously generated on the film when its backing is removed, is interposed between said region and the display surface, so that premature contact therewith is prevented and the film can be prepositioned with respect to the display surface.
Claim 3
Dependent Claim
54 words
A tool according to claim 1 which further comprises means for controlling the separation of the film from its backing in which a trailing section of the film is pulled away from its backing at the same time said portion of the film is being pulled across and in contact with the support member.
Claim 4
Dependent Claim
109 words
A tool according to claim 1 wherein the transparent region of the support member is further characterized as having an open, unbroken flat surface and wherein the guide element has means for controlling the separation of the film from its backing, the guide element being positioned so that a leading section of the side of the film lacking adhesive coating can be pulled across and in contact with said open, unbroken flat surface at the same time a trailing section of the film is being pulled away from its backing, thereby controlling a tendency of the film, without its protective backing, to be attracted to almost any proximate object.
Claim 5
Dependent Claim
92 words
A tool according to claim 1 wherein the aperture is further characterized as having a straight outer edge which is situated proximate a juncture of a wall of the aperture with the rearward branch and disposed approximately perpendicularly to a longitudinal axis of the through passageway, so that a leading portion of the side of the film lacking adhesive material can lie flat as it is being pulled across and in contact with the support member at the same time a trailing section of said film is being pulled away from backing.
Claim 6
Dependent Claim
81 words
A tool according to claim 1 wherein the holding means further comprises protrusions which extend from the support member and wherein the support member is further characterized as being formed of a resilient material and as being capable of being bent under the application of finger pressure a distance which is at least as great as the difference between the length of each protrusion in a direction perpendicular to the surface of the support member and the thickness of the film.
