Definitions

  • FIG. 4 is a view similar to FIG. 3 with the knob on the CLIPS T0 noLi) Kisoas 0N SHAFTS end the Shaft;
  • This invention generally relates to fastening or clip means for use to connect knobs to shafts and relates particularly to the retention clips used as a connecting device to mate and secure such knobs to a shaft.
  • Retention clips of this general type are common, as shown in the Hansen Pat. No. 2,968,504.
  • prior art is no longer ideal, for the reasons that these prior art'clips are not readily susceptible to being used in an applicator device for applying them into knobs, they are not provided in strip form for use in the applicator device, the configuration of the clips does not lend them to ready insertion in the knobs.
  • a primary object of the present invention is to provide a suitable retaining clip which may easily be handled by automatic applicator machinery.
  • a further object of the invention is to provide a clip such as to accommodate varying tolerances and discrepancies inherent in manufacture.
  • Another object is the provision of a clip with means to prevent rotary and axial movement between the shaft and the knob and which requires a minimum in tooling and is therefore inexpensive and easy to manufacture.
  • Still another object is to provide a clip with means to secure to clip in the knob such that axial and rotary movement between the clip and the knob is precluded.
  • Still a furtherobject is to provide a clip which may be secured permanently within a knob and may be removed from a shaft and re-used when required.
  • FIG. 1 is a perspective and exploded view of an end of the shaft, clip and knob according to the invention
  • FIG. 2 is a front end view of the clip
  • FIG. 3 is a longitudinal cross-sectional view of a knob with inserted clip
  • FIG. 5 is a view taken along the lines 55 of FIG. 4;
  • FIG. 6 is a perspective view of two clips shown in strip form.
  • Clip C used to secure knob K onto shaft S.
  • Clip C is formed out of spring steel or some similarly suitable material possessing the required spring characteristics and may be mass produced by fully automatic machinery.
  • the clip C is formed in a progressive die and manufactured in continuous strip CS, as shown in FIG. 6, which has holes H therein to be engaged by the feed mechanism of an automatic applicator device to feed the strip so that clips C are successively fed to a station at which the clips are severed from the strip and inserted within knobs.
  • the clip C is of generally split tubular form and it is tapered from the trailing end 1 to the leading end 2.
  • a transverse cross-section shows a channel U provided with a curved base 3 and sidewalls 4 and 5 having outwardly-extending portions 6 and 7 at the outer ends thereof.
  • the portions 6 and 7 provide horizontal support portions which extend upwardly into opposing arcuate members 8 and 9 which in turn terminate in flattened sections 10 and 11.
  • Sections 10 and 11 are raised at the trailing end -1 of clip C to include outwardly-projecting and beveled corners 12 and 13.
  • U-shaped channel 3 has an outwardly-curved tab 14 at the trailing end.
  • Portions 6 and 7, arcuate members 8 and 9 and sections 10 and 11 of clip C define a section D.
  • the clip is severed from the strip at tab 14 and inserted by means of a mandrel of an applicator device (not shown) into a large opening 15 of knob K.
  • Supporting shoulders 16 projecting from the wall of opening 15 engage support portions 6 and 7 of the clip.
  • flattened sections 10 and 11 frictionally engage the wall of D-shaped section 18 of opening 15 in which the D- shaped part of clip C is disposed.
  • opening 15 is intermediate the outer tubular dimensions of the ends of the clip C. Therefore, although tapered end 2 will easily slide into opening 16 with little force, as insertion of the clip progresses greater friction is experienced between the outer dimensions of the clip C and the wall of opening 15 which increases, particularly as upward-projection corners 12 and 13 engage the inner wall of the knob. Corners 12 and 13 assure that tab 14 maintains a biting engagement with the wall of opening 15. After insertion of the clip within the knob, the clip, although somewhat straightened, still retains most most of its taper.
  • the enlarged trailing opening of the clip still has a greater inner diameter than the outer dimensions of a D-shaped end of shaft S.
  • knob and the clip therein may be removed and re-used when required.
  • the outwardlydirected disposition of corners 12 and 13 when in knob K facilitates entry of the D-shaped end of shaft S within the clip C.
  • a clip for securing a knob to a D-shaped end of a shaft comprising a longitudinally split, resilient and tubular member having first and second longitudinal sections, said member being tapered from an area adjacent a leading end to a trailing end thereof, said first longitudinal section having a substantially D-shaped configuration and said second section having a U-shaped configuration.
  • a clip for securing a knob to a D-shaped end of a shaft comprising a longitudinally split, resilient and tubular member having first and second longitudinal sections, said member being tapered from an area ad- *jacent'a' leading'end'to a 'trailing'end thereof"; said-first longitudinal section having a substantially D-shaped configuration, and said second section having a U-shaped configuration, said U-shaped section having upwardly-directed sidewalls which terminate into outwardly-directed coplanar fianges, said flanges comprising the base of said D-shaped section, said D-shape'd vsection :being Ion tudinally split at the apex of its curvature.
