Definitions

  • a plurality of stepped resilient fingers or limbs are resiliently stressed inwardly as the support enters the aperture, and spring outwardly to engage the apertureedge of the panel at the rear thereof and retain a portion of the support tightly against the front face of the panel.
  • Key means may engage in a seat in the panel edge to preclude rotation of the support in the aperture.
  • the resilient limbs are provided in two or more sets, each set being of different configuration gages.
  • the invention is used to support a multi-tum precision potentiometer, which is a typical panelmounted instrument.
  • the invention is in the form of a cup-like device adapted to encircle and protect a portion of the supported device, and in the preferred form, support the instrument by attachment of the base or floor of the cup-like instrument supporting device to .the base of the supported'instrument, which in the illustration is a knob-enclosed potentiometer. Other modes of attachment may be employed as will become evident as the description proceeds.
  • the generally cylindrical body portion of the device or cup terminates at its forward end in a peripheral rim or flange that is dimensioned and shaped to abut against the front face of a panel adjacent the aperture.
  • the cup body is interrupted at spaced locations to provide longitudinal openings or recesses between the base and rim of the device, to provide'clearance for respective limbs comprised in sets of resilient limbs spaced around the body and each integral with the base and extending for wardly toward the rim and outwardly, and having at its,
  • the resilient limbs of the device are integral with the body of the device at the base and are so formed and constructed as to diverge outwardly away'from the longitudinal openings or interruptions in the body of the device when free, whereby when the device is forced, base first, through the receiving aperture in a panel, the
  • limbs are forced or cammed inwardly toward the axis of the aperture, and stressed, by cam action of the aperture wall on the inclined outer surfaces of the limbs, until one or more of shoulders of the steps at the ends of the limbs pass through the aperture and are free to spread outwardly to the. extent permitted by the next step of the series.
  • the device is thus pressed or: forced inwardly into the panel aperture until the flange or rim contacts the front face of the panel.
  • one of the inclined faces of the-steps on the outer face of each of the limbs of at least one set of limbs engages the rear corner edge of the panel at the aperture.
  • the engaged curved faces of the steps of the limbs exert forces on the panel that tend to pull or draw the device rearwardly, and hence serve to insure that the rim is firmly seated against the face of the panel.
  • the risers and treads'of the steps are not right-angled, but are inclined relative to both the axis through the aperture and the rear face of the panel, thelimbs not only effect a secure locking of the device in the aperture but also automatically'accommodate the limbs to a panel of any of a plurality; of thicknesses or gages.
  • the limbs automatically spring outwardly and compensate for any wearing at thefrisers.
  • the inclined risers and treads of the resilient limbs are preferably formed along arcs of circles all of diameter greater than the diameter of the aperture in the panel, that is, formed along arcs coincident with circles when thelimbs are in outermost and fully splayed 'positions
  • the limbs may be formed in position in their respective body openings or interruptions and with the step surfaces on arcs of circles of larger diameter than that of any aperture in which the device is to be used, and the limbs subsequently deformed outwardly under influence of heat and force so as to occupy positions outside the circular outline of any such aperture, it is evident that most superior results are attained with the preferred form of the device herein disclosed in detail strument in an aperture in any of panels of differing thicknesses.
  • Another object of the invention is to provide a readily-removable snap-in instrument supporting device for mounting an instrument in an aperture in a panel, which device automatically compensates for wearing .incident to moving contact with the panel.
  • An additional object of the invention is to provide an instrument supporting device comprising a rim portion for abutting the front face of a panel adjacent an aperture in the panel and having a rearwardly-extending body with forwardly-extending free-ended resilient cantilever limbs, the forward ends of which are stepped to engage the panel at the rear edge of the aperture and draw the rim portion snugly against the face of the panel irrespective that the panel may be of any of several different thicknesses.
  • FIG. 1 is a pictorial view, to no specific scale, depicting the presently-preferred exemplary embodiment of the invention
  • FIG. 2 is a side view of the device of the invention depicted in FIG.- 1, with portions sectioned and with an instrument nested in and supported by the device, the scale being somewhat enlarged and one feature exaggerated in the interest of clarity;
  • FIG. 3 is a rear face view of the device depicted in FIG. 1, to'enlarged'scale; J
  • FlG.'.4 is a front face view of the device depicted in FIG. 1, to enlarged scale;
  • FIG. 5 is a fragmentary sectional view, greatly enla'rged, showing a detail of the stepped end of a resilient limb of the device depicted in FIG. 1, with other portions of the device;
  • FIG. 6 is a fragementary enlarged sectional view illustrating details of the coaction of the device of the invention with a portion of an instrument supporting panel.
  • the device according to the invention is preferably formed of glass-fiber filled thermoplastic synthetic resinous material such as nylon or polytetrafluorethylene or similar material, by injection-molding techniques well known in the plastics molding industry.
  • the device 10 is formed with a flange or rim 10f of outer dimension or diameter somewhat in excess of the dimension or diameter of the panel aperture or hole into which the device is to fit, for example, one and one-eighth inch diameter in the case of a l-inch diameter panel aperture. As is indicated in FIG.
  • the device 10 comprises a body portion 10c that terminates at its rear in a base 10b.
  • the body portion is formed with sets of longitudinally-extending interruptions herein shown as openings, such as l0e, preferably uniformly spaced apart around the body.
  • resilient cantilever limbs such as 10w, 10x, 10y, and-102, which as indicated in FIGS. 1, 2 and 3 merge at their rear ends with the body portion and base 10b.
  • the resilient limbs shown are comprised in sets, limbs 10:: and 102 in one set and 10w.
  • all of the limbs may be otherwise identical.
  • Each of the limbs is of width less than the opening or interruption into which it may-be pressed or forced in the manner of a cantilever beam spring anchored at its rear end; each of the openings such as l0e being dimensioned to comfortably receive its respective cantilever limb without frictional contact.
  • all of the limbs may be identical and thus be comprised in only one set of limbs; or, as is preferred and shown, are paired into two sets in each of which sets the limbs are alike but different from those of the other set.
  • the body 100 of the device 10 is adapted to be pressed into an aperture such as that indicated at A in FIG. 2, the limbs resiliently entering into their respect'ive interruptions or openings lOe as their curved outer surfaces contact and are cammed inwardly by the surface or edge corner of the panel in the aperture.
  • the aperture A is shown exaggerated in diameter, in he interest of clarity. It is made only slightly greater in outline dimension or diameter than the outer outline dimension or diameter of the body 10c of the device immediately rearwardly of rim or flange 10f.
  • the forward ends of the resilient cantilever limbs are each formed with a plurality of steps the risers and treads of which are inclinded relative to the direction of the longitudinal-axis of the device and are inclined also relative to'the rear surface of the panel with which the limbs are in part adapted to coact, as is indicated in FIGS. 2, 5 and 6.
  • the principles of coaction of the steps of the limbs with the corner or marginaledge of the panel around the aperture are substantially-the same for all the limbs, hence the relationship of only one will be described in detail.
  • FIG. 5 and'another set such as .10w and 10y is formed quate to lock the device to a panel, and a larger range of gages or thicknesses of panels may be accommodated.
  • limbsof both sets may concurrently act to lock'or secure the device on the panel, and it is evident that, for example, the step formations on all of the limbs of the devicemay be While two sets of limbs, each set comprising a plurality of limbs, have. been illustrated, it is evident that a single set of three identical limbs will effectively act to secure the device to a panel, as would two sets each comprising three limbs, or other plural-limbsets. A single set of two limbs has been foundto be effective, since the flange 10f is effective to prevent wobbling of 40 the device in the aperture.
  • each'limb will contact the panel only at and immediately adjacent its side edges, such as at the locations indicated at E1 and E2 in F IG. 1, and not at any portion of the riser'or tread of the step between those locations.
  • the wear occurs at the locations such as E1 and E2 and the contacting surface area of the riser. or tread of the step merely becomes somewhat wider but does not adversely affect the locking action of the inclinedstep resilient limbs.
  • the device is formed with an external key or ridge 10!: (FIG. 1), dimensioned to be snugly received in an appropriately located notch in the periphery of aperture A in the panel.
  • the base lQb is t of electrical terminals or leads, or other means'extending from the instrument to be supported.
  • the base is formed with specially located and/or specially shaped and spaced-apart key holes, such as 10k, adapted to receive complementary and complementarily spacedapart rearwardly-extending fastener pins protruding from the rear of the instrument case.
  • the pins may be specially oriented as shown in FIG.
  • an instrument which may snugly fit inside the body of the device, may be firmly but .removably affixed to the panel by merely pressing the device home in the aperture.
