DOOR HANDLE ASSEMBLY Filed Sept.. 19, 1938 INVENTOR WILLIAM OQDEVEREAUX I ATTORNEY Patented Apr. 30, 1940 UNITED STATES PATENT OFFICE" 11 Claims.

This invention deals with door handle assemblies and more especially door handle assemblies having provision for locking the door handle shank firmly in place in the body of the door.

One of the objects of this invention is to provide a door handle structure composed of a plu- 'rality of parts capable of being readily assembled and locked in place in the door. A further object of this invention is to provide a door handle assembly having a positive locking means for the handle of a simple and inexpensive design.

With these and other objects in View, the invention resides in certain novel features of construction, combinations and arrangements of parts as will be more fully described and particularly pointed out in the appended claims. With reference to the drawing:

Figure 1 is a top plan view of the invention with the door sectioned away; t Figure 2 is a sectional view of the mountin cup taken along the lines 2-2 of Figure 1;

Figure 3 is a sectional view taken along lines 33 of Figure 2;

Figure 4 is a sectional view showing the method of removing the door handle;

Figure 5 is a view similar to Figure 1 showing a modification of the design; and,

Figure 6 is a sectional view taken along the lines 66 of Figure 5.- v

I With reference to Figure 1, it will be seen that the invention deals with adoor-handle such as I 0 having a shank H extending through the outer panel P2 of the door as well as through an escutcheon plate l3 on the exterior side of the door I2. Shank ll extends to the inner side M of the door and is maintained in place through vention resides in the construction of the mounting cup and clip in a manner to firmly lockthe shank ll in place inside the door body, which in turn assures proper location of the handle ID with relation to the escutcheon plate l3 and the outer panel of the door.

With reference to the invention more in detail, wherein like reference characters indicate like parts, it will be 'seen that the door panel I2 is provided with an opening ll through which shank may pass; On the inner side of panel l2 and surrounding this opening is a mounting cup 16. This cup isformed from a sheet metal stamping and has attached portions l8 extending laterally therefrom to provide'for attaching the cup inside of the, panel l2 by welding or the like. The bottom IQ of the cup is provi'dedwith an opening 20 in alignment with opening I i in the door through which the shank. H may also be extended.

The cup, as shown, is provided with an annular side wall having openings 2 I in diametrically op-' posite sides and having lugs 22 extending inwardly therefrom between the openings 2!. In the present instance the lugs are struck inwardly from the side wall of the cup. The cup is mounted on the door in a manner so as to have one of the openings 2| facing the swinging edge of the'door. stantially right angles to the openings 2!. The lugs 22 are designed so that the, free edges 23 are, spaced a sufficient distance from the ad.- jacent surface l9 of the cup to allow the leg 29 of the clip [5 to slide between the edges 23 of the lugs and the surface [9 of the cup.

Shank II is rectangular in cross section and has one end permanently secured within the end 24 of the handle H] in any suitable manner. As stated above, the shank is maintained in place in the door by the spring clip I5. This clip is formed of two substantially V-shaped

sheet metal members

25 and 26 identical except that the dimensions are so determined as to permit nesting the me'mbersj Both

legs

28 and 29 of the clip have openings 31] therein of suflicient dimension to allow the shank to pass 'therethrough when the legs are compressed to dispose the openings in parallel relationship to one another. Upon reference to Figure 3 it will be noted that the diametrically opposite sides of openings 30 on the legs of ,the clip are fashioned to form lips adapted to, have a'biting engagement with the adjacent sides of the shank when the pressure is released from the clip and the legs returned to their normal angularly related positions. It will be noticed that by providing two V-shaped

sheet metal members

25 and 26 instead of one that additional efiiciency is created. Instead of having two sets of lips 45 effecting' a biting engagement with the shank, actually there are four sets of lips. Not only is the wedging effect increased by the use of a clip in two parts instead of one, but also if one of the clips fails to function properly the locking effect of the remaining clip will be present.

After the clip is initially placed on the shank, the'shank is inserted into the door and rotated to effect locking of the clip with the cup. This is accomplished in the present instance by providing a lower leg 29 of the clip with two notches This will place the lugs 22 at sub-' 3| of suflicient size to allow the clip to slide over handle having a shank adapted to be inserted in a door, a spring clip mounted on the shankto 'form a unit with the latter and frictionally secured to the shank to prevent relative axial movement between the shank and clip, and

means carried by the door and cooperating with the clip to secure the shank in assembled relation with the door.

7. In a door handle assembly, an operating handle having a shank adapted to be inserted in a door, a spring clip mounted on the shank to form a unit with the latter and frictionally secured to the shank toprevent relative axial movement between the shank and clip, and means carried by the door and responsive to rocking movement of the shank and clip to engage the clip and prevent unauthorized withdrawal of the shank from the door.

8. In a door handle assembly, an-op'erating handle having a shank adapted to be inserted in the door, a clip having a portion apertured to freely receive the shank and normally urged to a position angularly disposed with respect to a plane perpendicular to the axis of the shaft to frictionally engage opposite edges of the opening with theadjacent sides of the shank and thereby lock the shank against axial movement relative to the clip, and means carried by the door and responsive to rocking movement of the shank and clip to engage the clip and prevent withdrawal of the shank from the door.

9. In a door handle assembly, an operating handle having a shank adapted to be inserted in the door, a clip having a portion apertured to freely receive the shank and normally urged to a position angularly disposed with respect to a plane'perpendicular to the axis of the shaft to frictionally engage opposite edges of the opening with the adjacent sides of the shank and thereby lock the shank against axial movement relative to the clip, a cup-shaped member carried by the door'forming a housing for the clip and having a projection responsive to rocking movement of the shank and clip to engage the clip and prevent withdrawal of the shank from the door.

10. In a door handle assembly, an operating handle having a shank'adapted to be inserted in a door, a spring clip mounted on the shank to form a unit with the latter and frictionally secured to the shank to prevent relative axial movement between the shank and clip, a cupshaped member carried by the door and adapted to house the clip, and projections on the cupshaped member efiective upon rocking movement of the shank and clip to engage said. clip and prevent withdrawal of the'shank from the door.

.11. Ina door handle assembly, an operating handle having a shank'adapted to be inserted in a door, a spring clip having diverging sides provided with openings therethrough dimensioned to freely receive the shank when the sides of the clip are flexed to a position wherein said sides are substantially parallel to one another, the opening in one side having an edge portion arranged to fixedly grip the shank in the angular position of the sides to prevent relative axial movement of the shank and clip, a cup-shaped member carried by the door and adapted to house the clip, and projections on the cup-shaped member responsive to rocking movement of the shank and clip to engage one 01' the sides of the clip and prevent axial displacement of the shank relative to the door. v
