. Jan. 17, 196? 5. 0. PUERNER MOUNTING MEANS FOR VARIABLE RESISTOR Filed Jan. 25, 1964 INVENTOR. GEORGE O PUERNER ATTORNEY United States Patent Office 3,298,641 Patented Jan. 17, 1967 3,298,641 MOUNTING MEANS FOR VARIABLE RESISTOR George 0. Puerner, Frankfort, Ind., assignor to P. R. Mallory & Co., Inc., Indianapolis, Ind., a corporation of Indiana Filed Jan. 23, 1964, Ser. No. 339,648 Claims. (Cl. 248-27) This invention relates to a snap-in means for insulatively mounting small control devices to a panel and more particularly to a means for increasing the breakdown voltage of a control to ground. The invention also provides a quick panel mounting means for a control.
The conventional manner of fastening variable resistors and the like to radio and television receiver panels is to provide a threaded bushing thereon which is secured to the panel with a threaded nut. It is also common practice to provide metallic mounting ears or tabs on such components and these cars or tabs may be either twisted or clinched over to secure the control to a panel. It is also known to provide metal brackets with resilient fingers formed at the ends which, when pushed axially into suitably apertured panels, will spring outwardly and engage the surface of a panel, depending upon spring tension to hold the control to the panel.
Generally, these conventional mounting methods have been satisfactory for certain applications. However, the bushing and nut construction is costly and, of course, grounded to the panel. Again, bushingless controls employing twisted or clinched metallic mounting ears or tabs are less expensive than the bushing and nut construction. However, these ears or tabs are also grounded to the panel and shaft wobble is more pronounced due to lack of a journal for the operating shaft.
Metallic snap-in type mounting brackets are still less desirable in that they not only are grounded to the panel but can be dislodged from the panel by a low axial force applied to the operating shaft. It is further evident that the high voltage buildup in present television receivers makes it necessary to provide adjustable controls which are safe for the service man or the user when making other than the usual tuning adjustments.
It is another object of this invention to provide a a mounting means for variable resistors and the like whereby such components are isolated electrically from metallic panels.
It is also an object of this invention to provide a mounting means for such components which integrally incorporate a shaft bearing supplementary to the short bearing which is typical in a bushingless control.
It is another object for this invention to provide a mounting means for variable resistors and the like which requires no separate mounting hardware.
It is still another object of this invention to provide a mounting means which requires no additional operations such as twisting or bending of tabs to secure such component to a mounting panel.
It is still another object of this invention to provide a mounting means for variable resistors and the like having protection against undesirable rotation in a mounting panel.
It is still a further object of the present invention to provide a variable resistor characterized by the aforementioned features.
Other objects of the present invention will be realized when the following description is taken in conjunction with the accompanying drawings which emphasize a variable resistor although I do not wish to be restricted thereto as it is contemplated that the present invention is applicable to other components such as switches, etc.
In the drawings:
FIGURE 1 is an exploded perspective view showing the manner in which the mounting means is used in conjunction with a variable resistor.
FIGURE 2 is a front view of the mounting means.
FIGURE 3 is a sectional view taken through the vertical center of FIGURE 2.
FIGURE 4 shows a variable resistor and mounting means assembly attached to a panel.
FIGURE 5 shows a panel typically apertured to receive the mounting means.
Generally speaking, the intention of the present mounting means is to provide a simple means for snapping a control into existing mounting holes in a metal chassis. Since it is a device made of insulating material having a certain amount of flexibility, for example, nylon, it also provides the spacing necessary to insulate the electrical terminals from the chassis. The spacing and resultant dielectric strength is proportional to the breakdown volt age resistance required.
The instant mounting means consists of a molded frontispiece 10 having a central bore 11 sized to provide a journal for control shaft 12 protruding forwardly from control 13. A notch 14 is provided in the outer periphery of frontispiece 10 to permit flush assembly of frontispiece 10 to insulative base 15 of control 13. Control 13 is suitably provided with a plurality of ears 16 which are clinched over the outer periphery 17 of frontispiece 10 to secure the assembly. Frontispiece 10 is further characterized by a plurality of resilient fingers 18 formed at the free ends thereof to provide hook-like projections 19 extending outwardly to a distance exceeding that between the outer edges of the apertures 20 in mounting panel 21 shown in FIGURE 5. Projections 19, when forced through apertures 20 snap into an overlying position on the opposite side of mounting panel 21 removably securing the control assembly to mounting panel 21. A sleeve or a plurality of integral bosses 22 terminate at an arbitrary line, the position of which is determined by the panel thickness. A split journal 23 having a tapered bore coinciding with a shorter bearing bore provides a concentric path for shaft rotation. The outside diameter of journal 23 fits into a standard (Retina) hole 24 which also receives the resilient fingers 18 adjacent to the journal.
