Definitions

  • a coat hanger which includes a telescopable and thereby extendable shaft extending between the hook and the -2ll/1l3, 115, 117
  • clothes support element(s) thereof with the maleand female portions thereof being lockable by a key upon 7 a twisting laterally of one of the male and female elements relative to the other the 'wedge portion of the end face causes the key projection to become depressed and thereby released from behind the lock step, and the key projection locking end portion furtherincluding a downwardly located end face wedgeshaped portion such that when the male and female portions are in the extended state with the key projection fully extended uponexit from within the female elements passage, the male and female member are compressible telescopically together without obstruction by the the extended key projection ,by virtue of the lower or dowardly located end face wedge-shaped portion becoming engaged with the female elements inner surface at the mouth of the female element to cause the key projection to become depressed to thereby ride into the passage of the female element along the inner wall surface thereof until upon reaching the step-down indentation lock within the surface of the female members inner wall surface the key pro-' jection becomes extended lockably again to reproduce a locked collapsed state.
  • the present invention is directed to a coat hanger of sufficiently'simple mechanism of operation for a child of young age to operate
  • the prior devices would most likely normally require adult intelligence and experience in order to make altering adjustments in length, as well as the cost of production being possibly exaggerated as compared to that of the present invention.
  • objects of the present invention include the obtaining of a telescoping device of simple mechanism of operation in so far as the mechanics thereof as well as the simplicity in operating the release and locking in the extending and collapsing alternately of the device.
  • Another object includes the obtaining of a coat hanger embodiment of such a telescoping device.
  • Another object is to obtain a locking and release mechanism simply lockable and releasable, for telescoping collapsed units.
  • Another objectv is to obtain a coat hanger of a telescoping hook shaft type which when collapsed is in the locked state supportable of normal weights supportable by conventional coat hangers without danger of accidentalextension of thetelescoped sections.
  • Another object is a coat hanger having telescoping hanger hook shank sections which when extended are collapsable into a locked collapsed state by mere unimpeded slidably collapsing the sections thereof manually, devoid of any need to manually release or open or hold open any key or the like.
  • Another object of the invention is'to obtain an efficient and low cost and durable locking key spring mechanism for the fulfillment of one or more of the preceding objects.
  • the shaft being the hook shaft of a coat hanger or pants hanger or the like such that the hanger may be extended or collapsed by a child or adult.
  • the mechanism of this lock device is the inclusion of a stepped recess-behind which the key projection becomes snapped into a lockedstate, in which associated with either the end face of the key projection or with the side of the stepped recess there is a laterally extending inclined planein the nature of a wedge ramp such that upon turning of the eylinderon which the key is mounted while holding the recessed key-engaging structure cylinder stationary, the end of the key becomes depressed againstthe outwardly biasing spring to thereby move laterally from behind the locking stepbarrier and thereafter allows the male and female members to be extended manually.
  • the inner surface of the outer is possible for the inner surface of the outer.
  • the preferred embodiment of the invention includes a spring-biased key which key does not rotate and with the keys outer face having an unaltered sharp-cornered upper edge which properly locks behind the step-down barrier upon .
  • the lower face of the outer end of the key is similarly inclined as a wedge such that when it is desired to.col-
  • the invention includes a novel lock and release device for atelescoping male and femaleshaft such that the shaft in the locked state does not extend when subjected to extending force, but upon twisting of the one ofthe male and female elements relative to-the other such that for example the inner cylinder is rotated relative to an outer female cylinder, the lock is thereby released permitting thereafter the extension of the collapsed telescoped male and female elements,
  • the extended key (that had previously been traveled from within the enclosing wall of the female element) does not block reentry of the male element in a collapsing action due to the edge of the ramp wedge of the lower face portion of the key becoming engaged beneath the mouth edge inner surface of the female enclosing wall to thereby cause the key to become depressed as the male part is forcibly collapsed telescopically into the female element.
  • Both female and male'elements are cylindrical in shape.
  • the male inner element is tubular also, and includes at least one aperture in a side face, with the spring mounted within the inner element tube and having the key supported on the spring such that the key is inserted intoand through and. extends beyond the aperture.
  • the preferred spring has been found to be a leaf spring, best mounted for efficiency as well as inexpensiveness thereof by utilizing the leaf spring in a U-shape with a second key on the tail of the spring and with a second aperture in a side of the tube opposite the other aperture with the tail key secured biasingly within the second aperture thereby both anchoring the U-shaped spring without need of brading .or the like, and simultaneously preventing any possibility of the turning or twisting of the locking key face of the locking key exor lip of the outer female element such that the male fully telescopically extended, toprevent disengagement of one from the other.

  • FIG. 4 illustrates a view as taken along lines 4-4'of FIG. '3 and-is an in part view taken in cross-section of the portion 19 of the FIG. 1 embodiment.
  • FIG. 5 illustrates a cross-sectional view as taken along'lines 5 5 of FIG. 3 of the embodiment of FIG.
  • FIGS. 1, 2, 3, 4 and 5 illustrate a preferred embodiment of the present invention in which a coat hanger has a telescoping extendable shaft embodying the inventive locking and release mechanism of the present invention, the coat hanger 8 having a hook 9 and clothing support shaft structure 10 mounted on' the base of the shank 11 above the lower circumscribing lip thereof, which shank 11 includes the upper male hook shank 12, the intermediate cylindrical shank portion 13 which serves at its upper end as the female-receiving space 22 for the section 12, and the shank cylindrical portion 14 having the space 26 into which the intermediate cylindrical portion 13 is invserted, the clothing support structure 10 being mounted on the lower female shank portion 14.
  • FIG. 4 illustrates the different shank portions 13 and 14, which serve to engage respective outwardly extending shank portions of themale member mounted therein such as outwardly extending flanges 25.
  • Such shoulder flanges serve to prevent the telescoping portions in their extended state as shown in FIG.
  • FIGS. 3, 4, and 5 A mainfeature of the invention is illustrated in each of FIGS. 3, 4, and 5 in so far as the key 15 includes a laterally inclined or slanted face laterally viewable in each of FIGS. 3 and 5, and a downwardlylocated downwardly inclined or slanted face 15 b as viewable in FIGS. 3 and 4.
  • the laterally inclined face 15a permits the key to have the face 15a slip under the edge of the structure defining hole 16 when the shank portion 13 is turned in a counter-clockwise direction as viewed in FIG.
