Definitions

  • the present invention is for an electronic sign and, more particularly, pertains to the construction of an electronic sign by using precise formed structures, rivets, nut inserts, and adhesive coated tape to assemble structural members of the sign.
  • Prior art electronic signs included a cabinet structure which was labor intensive in constructing and, therefore, time consuming, requiring alignment of components and subsequent drilling, riveting, welding and other techniques.
  • the components used for the fabrication of sign cabinets were extruded and not reliably true and straight, whereby suitable mating of components to the cabinet or mating of one cabinet to another adjacent cabinet proved to be not entirely satisfactory.
  • the general purpose of the present invention is to provide an electronic sign having a formed metal cabinet whereby the cabinet can be fabricated using precision formed channels, precision formed panels, and the like.
  • a plurality of formed components which can include precision cut or stamped channels, are combined to make a formed metal cabinet for use with electronic display modules to provide an electronic sign having a formed metal cabinet.
  • the components are considered to be formed components made by precise cutting, stamping, bending, laser cutting, and the like in order to provide uniformly shaped components of close tolerance and fit which can be planar two dimensional components or which can be multiple faced components in more than one plane.
  • a plurality of vertically oriented formed channels and formed mid-channels are secured and aligned between a formed top channel and a formed bottom channel.
  • Formed top, bottom and end panels include a plurality of different sized counter bored holes which can accommodate the flush mounting of rivet heads or nut insert heads.
  • a double-sided adhesive coated tape is used to secure and seal the formed top, bottom, and end panels to the appropriate formed channels and formed mid-channels.
  • a mounting panel for accommodating electronic display modules has counter bored holes therein to accommodate rivet heads.
  • a double-sided adhesive coated tape is used to secure and sealingly fasten the mounting panel to the front lips of vertically oriented formed channels and formed mid-channels and to the front lip of the formed top channel and to the front lip of the bottom formed channel.
  • a rear access panel is sealingly secured to the back lips of the vertically oriented formed channels and formed mid-channels and to the back lips of the formed top and bottom channels by the use of rivets and a double-sided adhesive coated tape.
  • the flush mounting feature of using counter bored holes allows for the vertical or horizontal alignment of one electronic sign to an adjacent electronic sign without any rivet head interference.
  • the use of rivets and nut inserts in conjunction with the use of a double-sided adhesive coated tape allows for the rapid assembly of the formed metal cabinet without having to drill matching holes between planar or channel components and without using other labor intensive construction techniques.
  • an electronic sign having a formed metal cabinet, including a central portion with vertically oriented formed channels, vertically oriented formed mid-channels, horizontally oriented top and bottom formed channels, horizontally oriented formed top and bottom panels, vertically oriented formed end panels, a mounting panel for accommodating electronic display modules, a rear access panel having access door panels, a plurality of double-sided adhesive coated tapes, and a plurality of rivets and nut inserts.
  • One significant aspect and feature of the present invention is to provide an electronic sign having a formed metal cabinet.
  • Another significant aspect and feature of the present invention is the use of precision cut and close tolerance formed planar panels or formed channels for simplifying the assembly process.
  • Still another significant aspect and feature of the present invention is the use of planar formed panels having counter bored holes for flush accommodation of rivet heads and rivet bodies and for flush accommodation of insert nut heads and bodies.
  • Yet another significant aspect and feature of the present invention is the use of a plurality of rivets and nut inserts or combinations thereof to fasten adjacent formed components.
  • a further significant aspect and feature of the present invention is the use of a double-sided adhesive coated tape as a seal and as an attachment interface between formed components.
  • Yet another significant aspect and feature of the present invention is the use of a plurality of rivets and nut inserts or combinations thereof in combination with a double-sided adhesive coated tape to fasten adjacent formed components.
  • Still another significant aspect and feature of the present invention is the use of formed sheet metal for supports instead of metal extrusions.
  • Yet another significant aspect and feature of the present invention is the use of formed sheet metal for supports instead of metal extrusions, whereby sheet metal can be formed more accurately and precisely than metal can be extruded.
  • Still another significant aspect and feature of the present invention is the use of rivets, nut inserts, and double-sided adhesive coated tape for fastening instead of weldments which require transfer of components in different stages of assembly to one or more welding areas.
  • Still another significant aspect and feature of the present invention is the use of prepunched and pre-counter bored holes that were punched by a CNC machine.
