Definitions

  • the present invention relates to a door handle connection, in general, and to such door handle connection with a pressure screw disposed in the pusher shaft, which pressure screw abuts a coupling element disposed in the pin of the other handle and urging into the wall of the pin entering opening, in particular.
  • two double levers engaged by a pressure screw are disposed next to each other in the recess of the handle pin, such that due to slight separation of the double lever, a resilient adherence thereof on the walls of the recess is obtained.
  • the double lever can also, with the same advantage, be retained in the recess by means of edge impressions.
  • the double lever has an upwardly directed supporting loop with rounded bottom edge which engages tightly in a coordinated hollowing at the bottom of the pressure pin recess.
  • the double lever has two digging teeth disposed in series relative to each other.
  • lever arm in order to bring about the same digging-in effect, form the lever arm as a convex extending 'blade spring anchored on the opposite side of the pressure screw and arranged convex on the longer lever arm in the direction of the pressure screw, which forms with a reversed curve apex the support from which an upwardly directed arm extends into the digging-in teeth.
  • FIGURE 1 is a top plan view of a door handle connection designed in accordance with the present invention.
  • FIGURE 2 is a longitudinal section of the door handle connection at an enlarged scale in non-tensioned position
  • FIGURE 3 is a longitudinal section of the door handle connection as shown in FIGURE 2 in its tensioned position;
  • FIGURE 4 is a section along the lines 44 of FIG- URE 2;
  • FIGURE 5 is a section along the lines 5-5 of FIG- URE 3;
  • FIGURE 6 is a top plan view of the pin with a particular embodiment of the double lever
  • FIGURE 7 is a longitudinal section of the connection indicating a resilient design of the double lever
  • FIGURE 8 is a longitudinal section of another embodiment of the door handle connection with a double lever designed as a blade spring
  • FIGURE 9 is a section along the lines 99 of FIGURE 8 in non-tensioned position.
  • FIGURE 10 is a section likewise along the lines 99 of FIGURE 8 in tensioned position.
  • the door handle 1 has in a handle neck 2 a square recess 3, in which a handle pin 4 is inserted.
  • a set screw 5 which is screwable in radial direction.
  • the handle pin 4 has a narrow longitudinal slot 6 extending through at about one half of the pin.
  • the slot 6 is disposed in a plane extending through two diagonally opposite edges of the square pin (FIGURES 4 and 5).
  • a double lever 7 serving as a coupling element and extending in longitudinal direc tion of the handle pin 4.
  • the longer lever arm 7' extending on the opposite side of a support 8 of the double lever 7 preferably stamped out of steel, sheet metal is engageable by the set screw 5.
  • the square pin is equipped with a cross recess 9.
  • the support 8 is formed by an upwardly directed loop or recess 7" with rounded bottom edge. A hollowing complementary thereto is provided at the bottom of the slot 6.
  • the short lever arm 7" forms due to a corresponding design upwardly directed teeth 11 and 12, respectively.
  • two digging-in teeth disposed in series relative to each other in the axial direction of the pin 4 are arranged,
  • the double lever 7 is stiff due to its edge cross section.
  • the longer lever arm 7' is formed resiliently by corresponding formation, for instance, as shown in the drawing.
  • a particularly great elastic resiliency is brought about by the embodiment disclosed in FIGURE 7 of the drawings, in which at the lower edge of the lever arm 7 recesses 13 are arranged, which favor an elastic bending of the lever arm
  • the double lever 7 can also, as shown in FIGURE 6, comprise two equal, thin walled pieces 7a and 7b, which bring about, due to an easy separation, a resilient adherence on the walls of the slot 6.
  • the upper edge of the double lever 7 is equipped with a recess 14, into which enter the edge-side impressions 15 of the slot 6 and secure the lever against falling out.
  • a correspondingly effective impression 16 provided at the tail end of the long lever arm 7 .
  • the handle 1 can, in accordance with FIGURE 2, be slipped on to the handle pin 4. Thereafter, the set screw 5 is screwed in.
  • the double lever 7 is thereby turned into the position shown in FIGURE 3, whereby the arm 7' abuts the bottom of the slot 6.
  • the teeth 11 and 12 formed on the shorter lever arm 7" dig-in, with especially greater force corresponding to the lever ratio, as shown in FIG- URE 5, into the walls 3' of the recess 3.
  • the upper edge of the lever 7 extends in tensioned position (FIGURE 3) towards the free end of the pin 4, in an upward tape. This brings about a protection against the removal of the handle 1 from the pin.
  • the set screw 5 is disposed in an oblique position of about to the wedge angle a of the lever arm position in the handle shaft 2.
  • FIGURES 8-10 A similar equal formation of the handle connection is disclosed in FIGURES 8-10.
  • the lever 7 is formed as a blade spring 70 anchored in the handle pin 4 by means of a bent over arm 17 in the bottom of the slot 6 on the opposite side of the set screw 5.
  • the blade spring runs bent convex in the direction of the set screw 5.
  • the blade spring 70 forms the support or bearing, from which an upwardly bent arm 19 extends into the digging-in teeth 20.
  • a door handle connection with a pressure screw disposed radially in a door handle comprising a two-armed lever having a longer and a shorter arm
  • said two-armed lever being supported near one end in said slot of said handle-four-edge pin
  • said slot being disposed in a plane extending through two diagonally opposite edges of said handle-fouredge pin and defining a bottom supporting said twoarmed lever.
  • said longer arm of said twoarmed lever extends within the range of said recess.
  • said supporting loop engages in a complementary manner the support recess at the bottom of said pin.
  • said two-armed lever forms with a reversely curved bow MARVIN CHAMPION, Primal-y Examiner said support, and
  • an p ardly directed arm extends from said support into E MCCARTHY, ssistant Examiner gripping teeth.
