Definitions

  • a light filter is positioned over the bulb and is secured to the socket so that light emin-ating from the bulb passes through the filter.
  • Cam and shoulder elements are formed integrally with either the socket or the filter for the purpose of attaching the socket-filter assembly to an aperture of a mounting panel.
  • the socket-filter ⁇ assembly may be provided with a locking tab member for reception into a cut-out portion of the aperture of the panel for the purpose of locking the socket-filter assembly from rotative movement with respect to the panel.
  • This invention relates to a bulb socket-filter assembly adapted to be mounted directly into an aperture of a mounting panel and, more particularly, to such a bulb socket-filter assembly which is provided with a locking tab member that enters a cut-out portion of the aperture to ⁇ lock the socket from substantial rotative movement with respect to the mounting panel.
  • bulb sockets are utilized as supporting structures Ifor the light bulbs associated with various ones of the instruments contained on the dash board. To provide the proper lighting intensity and hue on the instruments, it has been necessary to provide a cover or ⁇ light filter over the sockets attached to the mounting panel. In general, these covers or light filters are slightly larger than the ⁇ aperture of the dash board to which the bulb socket is assembled. The lters are placed over a selected aperture in the mounting or dash panel and attached to the ⁇ front of the panel by small screws, rivets or other such fastening devices. The panel is then turned over and the bulb socket, with 'a light ⁇ bulb contained therein, inserted into and secured to the panel from the rear surface thereof.
  • the above described m-anner of attaching separated yfilters and sockets to -mounting panels has several operation-al steps which require diverse and time consuming hand operations.
  • the bulb socket-filter assembly of this invention substantially reduces the time requirement of the -prior ⁇ assembly operations, provides a better ylight filter for the bulb socket and provides a means of attaching to the dash panel, in sin-gle step, both the socket and the filter.
  • This invention is directed to a bulb socket-filter assembly adapted to be inserted into an aperture of a mounting panel.
  • the bulb socket-filter assembly is not only secured to the mounting panel in a single operational step but also, in its preferred embodiment, is Ilocked with respect to the mounting panel against rotative movement such that the socket will not become loosened or otherwise disengaged from the mounting panel when the mounting panel is subjected to shock or other vibrational forces, yas for example, when the mounting panel is utilized as the dash board of an automobile.
  • the bulb socket-filter assembly of this invention is formed such that a major portion of the Mice socket is an insulating body which defines a cavity open at one end, the cavity containing terminals for receiving and supporting the base of ⁇ a bulb.
  • a light filter is attached to the insulating body to form -a bulb socket-filter assembly.
  • the socket-filter assembly has elements integral therewith which cooperate with the mountingg panel for securing the assembly to the mounting panel.
  • a deflectable locking member is also provided which is integral with and extends from the socket-filter assembly.
  • the Ilocking member is deflected during insertion and initial securing of the assembly to the panel and, after initial insertion, the locking member is received within a cut-out portion of the aperture of the mounting panel. Since the locking member is integral with the socket-filter assembly and received within a cut-out portion of the aperture, it is effective to lock the a'sssembly against substantial rotative movement with respect to the mounting panel. Thus, after full insertion of the assembly, shock or vibrational force applied to the mounting panel will not result in a loosening of the assembly from its engagement with the mounting panel.
  • FIGURE 1 is an elevational view of the preferred bulb socket-.filter assembly of this invention in a disassembled condition.
  • ⁇ ElIGURE 2 is a plan view of a typical mounting panel to which the bulb socket-filter assembly may be secured and locked.
  • FIGURE 3 is an elevational view showing the preferred bulb socket-filter assembly of this invention in an assembled condition.
  • FIGURE 4 is a plan view of the upper side of the mounting panel with the bulb socket-filter lassembly secured thereto.
  • FIGURE 5 is a cross sectional view of the bulb socket-filter assembly taken along 'line 5--5 of FIGURE 4.
  • FIGURE 6 is a cross sectional view of the bulb socket-filter assembly taken along line 6-6 of FIGURE 5.
  • the socket of the assembly will be ⁇ described as being of the type utilized in conjunction with baseless bulbs. However, it should be understood that this is not the only type of bulb which may be utilized with the assembly of this invention as the socket may be adapted to receive other types of bulbs by changing the terminals associated with the socket.
  • the preferred embodiment of the bulb socketlter assembly of this invention is also described in conjunction with its utilization in a mounting panel or dash panel of a motor vehicle. It should also be understood that the use of the bulb socket-filter assembly in this particular application is merely illustrative and that the assembly may be utilized in many other applications other than in the -dash boards of motor vehicles.
