Definitions

  • indicating mechanisms are generally mounted in frames or encasing elements consisting of easily machined materials, such as wood, plastics, etc., in order to give them support and more particularly to increase the aesthetic appearance of the assembly, by sculptures or decorations.
  • the invention aims at providing a fastener permitting a simple securing of the case of instruments on their surrounding or setting.
  • the invention provides means permitting instantaneous separation between the case and said setting, thereby permitting many dismantlings and the positioning as desired of the two members one with respect to the other.
  • the invention results in an improved appearance and simplified assembly as well as a decrease in production costs.
  • the invention is concerned with a fastening ring secured on the encasing element ornamenting a case containing a mechanism (e.g. a barometer), characterised in that it receives the cylindrical body of the case and retains it by resilient concentric clamping.
  • a mechanism e.g. a barometer
  • FIGURE 1 is a bottom view of the elastic fastening ring according to the invention.
  • FIGURE 1 is a detailed view of a securing leg depending from the flange.
  • FIGURE 2 is a plan view partially cut away from the assembly accordng to the invention.
  • FIGURE 1 Reference is first made to FIGURE 1.
  • Ring 1 is cut from a plate of elastic material, for example of steel ribbon, in such a way as' to have a crown shape.
  • the outer periphery 2 is circular, while the inner periphery has circular slots 3 separated by portions 4 of the same circle, which after flanging will form as many spring blades.
  • the crown plate is then flanged so as to obtain a tube 5 (FIG. 2) concentric and perpendicular to the outer periphery and which joins the initial plane by means of a head or fillet 6 (FIG. 2) having a rather large radius.
  • a tube 5 (FIG. 2) concentric and perpendicular to the outer periphery and which joins the initial plane by means of a head or fillet 6 (FIG. 2) having a rather large radius.
  • a head or fillet 6 FIG. 2 having a rather large radius.
  • the circular bore 10 is made in a setting 9 of the apparatus and has a diameter greater than the outer diameter of tube 5.
  • Ring 1 is positioned concentrically to bore 10 and pressed on the setting 9 in such a way that the outwardly flaring legs 7 penetrate into the said setting or come Into snap-0n engagement therewith.
  • legs 7 causes a sure fastening.
  • the part 12 of the casing is force fitted in tube 5 and is retained by the spring blades of the periphery.
  • ring 1 can take all geometrical shapes capable of maintaining and clamping bodies 12 of instrument cases.
  • Fastener for securing the case of an indicating mechanism in an encasing element which has a walled opening therein, said fastener being insertable in said opening and comprising an unthreaded, tube shaped ring adapted to receive therein said case; said fastener having a circular 3 4 outer periphery and an inner periphery including inwardly References Cited directed case gripping spring blades separated by arcuate UNITED STATES PATENTS cut-outs and a flange at the upper part thereof, said flange 1,042,297 10/1912 Voight 70370 overlapping the upper end of said walled opening and a 2 244 976 6/1941 Tinnerman 85 32 plurality of leg members depending from said flange in 5 2610012 9/1952 Mackey et engagement with the walls of said walled opening.
