Definitions

  • This invention relates to mounting devices and more particularly to self-locating mounting devices. Still more particularly, it relates to a self-locating light-shield for an automotive headlight.
  • Automotive headlights can employ a halogen bulb mounted in a reflector.
  • the forward-facing portion of the bulb is shielded.
  • the shield has been affixed to a push-in mount that does not adequately position the shield and occasionally falls out.
  • Proposed solutions using a screw-in mount are workable but expensive and require extra parts and handling.
  • Yet another object of the invention is the enhancement of automotive headlight assemblies.
  • Still another object of the invention is the enhancement of push-in shield mounting systems that are self-positioning and easily maintained in an appropriate location and that are easily removable in the event parts are scrapped, allowing the light shields to be salvaged.
  • a self-locating mounting system comprising a housing containing a mounting receptacle with three closed sides and an open side, a substantially solid bottom containing a laterally extending slot and a top containing an opening; a first sub-assembly having only a planar surface with an aperture therein, a solid rear wall and a depending side wall, said depending side wall being formed to engage said laterally extending slot in said housing and protrude therefrom; a second sub-assembly comprising a body with an upper surface and four walls including a front, back and two sides; a compressible lock associated with said upper surface; a first spring associated with one of said sides; and a second spring associated with said back; said first sub-assembly being positioned atop said second assembly with said compressible lock penetrating said aperture in said planar surface, said first spring engaging said depending side wall and said second spring engaging said solid rear wall, said first and second sub-ass
  • An appropriate shield can be affixed to the depending sidewall.
  • This self-locating mounting system applies tension in X, Y and Z directions to orient the depending sidewall and the collapsible lock removably fixes the entire assembly in place.
  • Fig. 1 is a perspective view of a housing utilized with the invention
  • Fig. 2 is a perspective view of a first sub-assembly
  • Fig. 3 is a perspective view of a second sub-assembly
  • Fig. 4 is an elevational sectional view taken along the line 4-4 of Fig. 2;
  • Fig. 5 is a plan view of an assembled mounting system, partially in section.
  • Figs. 6 and 7 are elevational sectional views taken along the lines 6-6 and 7-7 of Fig. 5.
  • a self-centering mounting system 10 having a housing 12 containing a mounting receptacle 14.
  • the mounting system can be part of an automotive headlight reflector.
  • the mounting receptacle 14 has three closed sides, 16, 18, 20, an open side 22, a substantially solid bottom 24 provided with a laterally extending slot 26 and a top 28 containing an opening 60.
  • a first sub-assembly 30 is shown in Fig. 2 and has only a planar surface 32 with an aperture 32 therein, a solid rear wall 36 and a depending side wall 38. When assembled, the depending sidewall 38 will fit into slot 26 and protrude therefrom.
  • a second sub-assembly 40 (Fig. 3) comprises a body 42 having an upper surface 44 and four walls including a front wall 46, a back wall 48 and two sides 50 and 52.
  • a compressible lock 54 in the form of a planar spring is associated with the upper surface 44 and a first spring 56 is associated with side 50 and a second spring 58 is associated with the back 48.
  • the second sub-assembly is hollow and the springs and the compressible lock are formed from the material of the upper surface and the respective sides. This provides a structure that is light in weight and easy to manipulate. However, if desired, separate springs can be appropriately affixed to their respective surfaces in any convenient manner.
  • the first sub-assembly 30 is positioned atop the second sub-assembly 40 with the compressible lock penetrating the aperture 34 in the planar surface 32, the first spring 56 engaging the interior side of the depending side wall 38 and the second spring 58 engaging the interior surface of the back wall 48. Maintaining the units in this position the entire assembly is pushed into the mounting receptacle with the depending wall 38 slipping into slot 26. Insertion is completed when the compressible lock 54 penetrates the opening 60. At this point pressure from second spring 58 presses the back 36 of the first sub-assembly against wall 18 and simultaneously presses the assembly forward toward the open side 22.
  • the depending wall 38 is provided with a light shield 70 in the form of a hollow hemisphere, as is shown in Fig. 4.
  • the light shield will engage and cover the forward most area of the headlight light source. Covering the front area of the light source eliminates a perception of a point source of light that can be distracting to oncoming drivers.
  • the sub-assemblies 30 and 40 are constructed of a suitable material.
  • the depending sidewall 38 can be formed of 1018 CRS and the cup 70 can be formed from 1010 or 1008 CRS and can be 0.50 mm thick.
  • Sub-assembly 40 is preferably formed from 1050 spring steel such as R c 42-50 or SAE 1074 high carbon spring steel or HD galvanized. Material on the order of 0.8 mm thickness is preferred.
