Definitions

  • This invention relates to display devices, and particularly to a display device in which a display panel is received in a frame.
  • a more specific object is the provision of a framed display panel whose circumference is circular, elliptical, or otherwise continuously convex in a closed loop about the major faces of the panel.
  • the invention resides in a display device comprising a panel having two major faces and a circumferential face portion connecting the major faces and extending in a continuous, convexly arcuate closed loop.
  • the device further comprises an annular frame of yieldably resilient, synthetic resin composition which is of approximately C-shaped, uniform cross section.
  • the frame includes an elongated web portion having one concave and one convex longitudinal face, two elongated web portions which project from the concave face of the web portion in transversely spaced relationship, and an elongated reentrant portion on each flange portion remote from and approximately parallel to the web portion.
  • Each re-entrant portion is directed toward the re-entrant portion on the other flange portion, and the circumferential face portion of the panel is received between the re-entrant portions of the frame.
  • FIG. 1 shows a circular display device of the invention in fragmentary section through its axis
  • FIG. 2 shows the device of FIG. 1 in a perspective view
  • FIG. 3 illustrates a modification of the device of FIG. 1 in a corresponding view
  • FIG. 4 shows a portion of the frame in the device of FIG. 3 in a fragmentary, exploded, perspective view
  • FIG. 5 shows the apparatus of FIG. 3 assembled with a bracket in partly sectional plan view.
  • FIG. 1 there is seen a display device of the invention whose most conspicuous element is a laminar, circular panel 10.
  • the panel consists of a backing disc 12 of stiff polystyrene and two pliable discs 14 of paper carrying the imprint to be displayed on the major exposed faces of the panel.
  • the three layers of the panel 10 are held in superimposed relationship by a frame 16 which consists of a unitary length of extruded, plasticized polyvinyl chloride, bent into a closed loop.
  • the extruded material is approximately C-shaped in cross section.
  • An elongated web 18 of the frame is cylindrical corresponding to the configuration of the circumferential face portion of the panel 10.
  • Two elongated flanges 20 are flat circular rings projecting from the concave face of the web l6 in transversely spaced relationship.
  • An elongated reentrant or inturned portion 22 of the frame 16 remote from and approximately parallel to the web 18 on each flange 20 is directed toward the re-entrant portion on the other flange.
  • the dimensions of the panel 10 and of the frame 16 are selected in such a manner that the circumferential face portion of the panel 10 is received between the two re-entrant portions 22 under resilient pressure.
  • the two ends of the extruded shape which forms the frame 16 are joined to each other by welding, or heatsealing, as indicated by the welded seam 24 shown in FIG. 2.
  • the seam may be formed before the frame 16 is assembled with the panel 10, the frame material being sufficiently resilient to be slipped over the panel 10, but welding or heat-sealing after assembly may be preferred with large display devices.
  • the panel is not significantly dif ferent from the panel 10 illustrated in FIGS. 1 and 2. It includes a central, rigid disc 112 covered on both sides with indicia or imprint-carrying sheets 114 of more pliable paper.
  • the annular frame 116 which holds the plastic and paper discs of the panel 110 in the illustrated condition may consist of the same plasticized, and therefore resilient, polyvinyl chloride composition described above.
  • the frame 116 also is produced by extruding the plastic composition, and by bending the extrudate into a circular loop shape conforming to the panel 110.
  • the cross section of the frame 116 differs from that of the frame 16 by curled edges 126 on the re-entrant portions 122.
  • the latter are located approximately in a common surface parallel to the concave inner face of the web 118, and the two edge portions 126 are located in parallel radial planes and provide a unitary connection between the re-entrant portions 122 and the web 118.
  • the two edge portions 126 and the web 118 thus bound a seamless groove 128 in which the circumferential face portion of the panel 110 is received.
  • each edge portion 126 together with the associated re-entrant portion and flange and a part of the web 118 bounds a longitudinal, approximately square bore 132 in the frame 116, and the loop of the frame 116 is closed by means of two connectors 130.
  • the connectors are pins made of square, metallic, bar stock of slightly greater cross section than that of the bores 132, and transverse grooves are cut into the longitudinal faces of the connectors in such a manner as to form barbs which permit easy insertion of the tapering ends of the connectors 130 into the longitudinally terminal portions of the bores 132, but impede withdrawal of the connectors.
  • the frame 116 thus may be assembled about the sandwich structure of the panel 110 by means of two connectors 130 to constitute the 3 only means holding the several layers of the panel in the assembled condition
  • the two framed panels resp ctively shovn in FIGS. 1 and 3 may be suspended from or held upright by a bracket 40 of the type shown in FIG. 5 in its cooperation with the frame 116 and panel 110.
  • the bracket 40 essentially consists of two. two-armed. sheet metal levers 42,44, a pivot pin 46 connecting respective ful crum portions of the levers. and a torsion spring 50, partly helical and coiled about the pin 46.
  • the levers 42,44 have respective first arms 42a.44a whose faces have recesses 42".44c shaped conformingly to receive respective flange portions of the frame 116 and parts of the web portion of the frame.
  • the re Stepd faces of the first arms are opposite each other and biased toward abutting engagement with each other by the spring 50 which consists of spring-temper steel wire. and whose ends tend to move the second legs 42b.44b of the levers 42,44 apart.
  • the frame 116 thus is firmly clamped between the first iegs 420,44a, and the second legs 42b,44b normally diverge from the pin 46 as is shown in FIG. 5.
  • the free ends of the second legs and a circumferential portion of the frame 116 thus provide a three-point support for the display device on any horizontal surface.
  • the second legs 42!).44b are readily accessible, and may be moved manually toward each other against the biasing force of the spring 46 to release the frame 116 from the clamping engagement of the legs 42a,44a.
  • the frame 116 may then be stripped from the panel 110, and the indicia-bearing pliable paper sheets 114 may be replaced by others bearing a different imprint.
  • Extruded plasticized polyvinyl chloride shapes of the type employed in the frames of the invention are so inexpensive as to be disposable together with the panel which they frame when the display device has performed its function and is no longer needed.
  • a new display device is readily fashioned from a backing disc of plastic. cardboard. or like stiff material. pliable facings carrying a message. and a new length of extruded frame material.
  • a torch or other simple heating device is needed for assemblying a frame of the cross section shown in FIG. 1. but no tools whatsoever are needed for assembling a frame from material of the shape shown in FIGS, 3 and 4 by means of connectors, such as the barbed pins 130.
  • the panel and frame need not be circular, but may be elliptical, ovoid. or of any other shape bounded by a continuous. convex loop which permits a smooth fit of the frame material and the panel circumferencev An angular corner on a panel is not readily accomodatcd.
  • a display device comprising. in combination:
  • annular frame of yieldably resilient, synthetic resin composition said frame being of approximatcly C-shaped, uniform cross section and including an elongated web portion having one concave and one convex longitudinal face.
  • two elongated flange portions projecting from said concave face in transversely spaced relationship, an elongated re-entrant portion on each flange portion remote from said web portion and directed toward the reentrant portion on the other flange portion, and an edge portion on a part of each re-entrant portion remote from the associated flange portion.
  • edge portion extending from said re-entrant portion to said web portion and being integrally connected to said re-entrant and web portions, each edge portion jointly with the associated re-entrant and flange portions and with a part of said web portion bounding a longitudinally open bore in said frame.
  • said circumferential face portion of said panel member being received between the edge portions of said frame.
  • said frame essentially consists of a continuous, unitary, elongated body of said composition, and at least one connector simultaneously received in the two longitudinally open terminal portions of said bore and connecting the two longitudinal ends of said body.
  • said panel member includes three of said disc members, two of said disc members being of pliable material and constituting said major faces, and the third disc member being interposed between said two disc members and consisting of material more rigid than said pliable material.
  • a display device comprising, in combination:
  • a panel member having two major faces and a circumferential face portion connecting said major faces and extending in a continuous, convexly arcuate, closed loop;
  • annular frame of yieldably resilient, synthetic resin composition said frame being of approximately C-shaped, uniform, cross section and including 1. an elongated web portion having one concave and one convex longitudinal face,
  • each re-entrant portion remote from the associated flange portion, said edge portion extending from said re-entrant portion to said web portion and being integrally connected to said re-entrant and web portions,
  • each edge portion jointly with the associated reentrant and flange portions and with a part of said web portion bounding a longitudinally open bore in said frame
