DESCRIPTION OF THE PREFERRED EMBODIMENT In the exemplary embodiment of the invention as disclosed in the drawing, an electrical switch generally designated 10 is shown to be mounted in a housing 11 of an electrical appliance, which in the illustrated embodiment comprises a vacuum cleaner 12.
More specifically, in the illustrated embodiment, vacuum cleaner 12 comprises an upright vacuum cleaner wherein the housing 11 comprises the nozzle, or base, portion of the vacuum cleaner with a handle 13 movably connected to the nozzle and carrying a conventional dirt collecting bag 14. The vacuum cleaner may include a conventional motor operated fan 15 disposed within the nozzle 11 and arranged to be energized through a suitable electrical cord 16, under the control of switch 10.
In the illustrated embodiment, switch 10 is mounted in a rear portion 17 of the nozzle with an actuator por tion 18 of the switch projecting outwardly from the rear wall 19 of nozzle portion 17. As shown in FIGS. 4 and 5, switch 10 is received in a one-piece combination switch holder and switch operator element generally designated 20 and the assembly of the switch in element 20 is received in a wall portion 21 of the nozzle 11 defining a cavity 22. As shown in FIG. 5, wall portion 21 defines an insertion opening 23 and an exposure opening 24. When the switch 10 is installed in element 20 and the assembled structure 51 installed in the cavity 22, switch actuator 18 projects outwardly through exposure opening 24, as shown in FIG. 4.
More specifically, element 20 includes a first portion defining a switch holding means 25, a second portion defining switch engagement means 26, and a third portion defining hinge means 27 hingedly connecting the engagement means 26 to the switch holding means 25, as best illustrated in FIG. 5. In the installed arrangement of the assembly 51, as shown in FIG. 4, switch holder portion and hinge means 27 are disposed within the cavity 22 with the switch engagement portion 26 disposed outwardly of the cavity in overlying relationship to switch actuator 18 for engagement therewith as a result of suitable operation of the engagement means by the user to effect desired operation of switch 10.
More specifically, switch holder portion 25 comprises a generally parallelepiped receptacle having a front wall 28, side walls 29, top wall 30 and bottom wall 31 cooperatively defining an open rear portion 32 for movement of the switch forwardly through open portion 32 with the actuator portion 18 extending coaxially through an inturned annular flange 33 and front opening 34 of front wall 28. Suitable electric leads 35 connected to switch 10 may be brought out rearwardly through the open rear portion of the switch holder for connection to the electrical system of the vacuum cleaner.
As shown in FIG. 4, the side walls 29 of the switch holder extend rearwardly into abutment with the wall 21 defining the cavity 22. Wall 21 may be provided with a pair of ribs 36 extending vertically to engage the rear surface 37 of the switch and retain it snugly against the annular flange 33. Bottom wall 31 is shorter than side walls 29 to define a space 38 through which the leads 35 are brought from switch 10. A lower extension portion 39 of the switch holder 25 projects downwardly from bottom wall 31 forwardly of housing wall 19 into engagement with the bottom plate 40 of the vacuum cleaner which is normally secured across the lower end of the nozzle 11 by conventional suitable means such as screws 41 threadedly engaging suitable support posts 42 of the nozzle. The top wall 43 of the nozzle portion 17 is provided with a plurality of downwardly projecting ribs 44 which are engaged by the hinge portion 27 of element 20 and as a result of the resiliency of the hinge portion, resiliently snugly retain the element 20 in cavity 22 against the secured bottom plate 40.
Hinge portion 27 defines a pair of integral hinges 45 and 46 and an interconnecting portion 47 between the hinges. As shown in FIG. 4, first hinge 46 is folded to extend midportion 47 outwardly through cavity 22 from the inner end of the top wall 30 of the switch holder portion 25. Second hinge portion 45 extends outwardly through the exposure opening 24 to dispose the engagement portion 26 of element 20 outwardly of switch actuator 18. As best seen in FIG. 4, engagement portion 26 includes a pedal portion 48 and a force transfer portion 49. Hinge portion 45 may be arranged to space the force transfer portion 49 normally outwardly of switch actuator 18 whereby depression of pedal 48 swings the force transfer portion 49 into engagement with the switch actuator 18 permitting inward movement of the actuator to operate switch 10 to control the vacuum cleaner operation. Thus, the switch actuator is normally free to prevent hindrance of the resetting of the switch upon completion of an actuation operation.
The upper surface 50 of the pedal 48 may be serrated for improved positive engagement by the users foot in controlling the operation of the vacuum cleaner.
The one-piece combination switch holder and switch operator 20 may be economically formed as a molded element of synthetic resin with the hinge portion 27 extending generally away from the holder portion 25 in the original, formed arrangement thereof. To install the assembled switch 10 and element 20 in the cavity 22, the engagement portion is firstly brought through the bottom insertion opening 23 of the cavity and swung rearwardly through the exposure opening 24 while the hinge portion and switch holder portion 25 are moved downwardly into the cavity, with the cavity opening upwardly as shown in FIG. 5. The hinge portion 27 is automatically disposed to be brought into engagement with the ribs 44 and thereby dispose the engagement portion 26 in the desired overlying relationship to switch actuator 18, as shown in FIG. 4, with the assembly being retained in cavity 22 by the nozzle bottom plate 40 as discussed above.
Thus, the switch holding means of the present invention is extremely simple and economical of construction and permits facilitated low cost installation in the vacuum cleaner housing nozzle without the need for separate fastening means. Removal of the assembly as for servicing or replacement of the switch may be readily effected by simple removal of the vacuum cleaner bottom plate 40 and reverse, withdrawal movement of the assembly from the cavity 22.
The switch is spaced from the bottom plate 40 and retained within the molded plastic nozzle portion 21 so as to be effectively insulated from metal parts of the vacuum cleaner by the synthetic resin material of the element 20 including the spacing means defined by extension 39 positioning the switch holder portion 25 substantially above the plate 40 as seen in FIG. 4.
