Abstract
Abstract A retainer device for translucent plastic panels or faces for illuminated signs whereby to secure the panels against displacement from the sign housings or frames by wind pressures thereon. The plastic panels, being flexible and subject to lateral expansion and contraction under varying temperature conditions, are customarily installed in their frames with liberal marginal tolerances thus, when flexed by wind pressures at relatively low temperatures, the face panels can escape their mountings resulting in damage thereto.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
80 words
A retainer device for plastic face panels for illuminated signs having a housing and a frame in said housing defining a channel to receive the marginal edges of said panels and providinG a mounting therefor, the improvements comprising: an integral rib formed longitudinally of one wall surface internally of said channel, the said panels having a marginal abutment facing said rib in said channel and engageable therewith in any lateral movement of said panels under stress of wind pressures thereon.
Claim 2
Dependent Claim
80 words
A retainer device for plastic face panels for illuminated signs having a housing and a frame in said housing defining a channel to receive the marginal edges of said panels and providinG a mounting therefor, the improvements comprising: an integral rib formed longitudinally of one wall surface internally of said channel, the said panels having a marginal abutment facing said rib in said channel and engageable therewith in any lateral movement of said panels under stress of wind pressures thereon.
Claim 3
Dependent Claim
40 words
A retainer device for plastic face panels for illuminated signs, as described in claim 1, wherein the said marginal abutment on said panels comprises a plastic strip cemented to the surface thereof adjacent to said integral rib in said channel.
Claim 4
Dependent Claim
24 words
A retainer device as described in claim 1, wherein the integral rib in said channel is spaced from the inner periphery of said frame.
Claim 5
Dependent Claim
147 words
A retainer device for plastic face panels for illuminated signs having a housing and a frame in said housing defining a channel to receive the marginal edges of said panels, and providing a mounting therefor, in combination, an abutment strip on each of said panels along and adjacent to the marginal edges thereof and enclosed within said channel when said panels are arranged in said frame, a clip detachably securable to said frame at spaced intervals therearound having means formed therewith engageable with said abutment strip when said panels are moved laterally in any direction in said frame, the said means comprising an angular lip formed along one edge of said clip for overreaching the inner peripheral edge of said frame and into said channel, and a tensile right-angular flange formed on said clip opposite said lip for engagement with the outer peripheral edge of said frame.
Claim 6
Dependent Claim
147 words
A retainer device for plastic face panels for illuminated signs having a housing and a frame in said housing defining a channel to receive the marginal edges of said panels, and providing a mounting therefor, in combination, an abutment strip on each of said panels along and adjacent to the marginal edges thereof and enclosed within said channel when said panels are arranged in said frame, a clip detachably securable to said frame at spaced intervals therearound having means formed therewith engageable with said abutment strip when said panels are moved laterally in any direction in said frame, the said means comprising an angular lip formed along one edge of said clip for overreaching the inner peripheral edge of said frame and into said channel, and a tensile right-angular flange formed on said clip opposite said lip for engagement with the outer peripheral edge of said frame.
