Application November 26, 1956, Serial No. 624,472

1 Claim. (Cl. 292-228) Our invention relates to a new type of closure and lock designed for use on a door.

One of the objects of our invention is to provide a door lock and closure the installation of which will require drilling only one hole through the door.

It is a further object of our invention to provide such a door lock which is fool-proof, easy to install and simple to operate.

A further object of our invention is to provide such a lock and closure especially suited to be adapted for use on outside screen doors and storm doors which are in common use today. Further objects and advantages of our invention will appear in the drawings and specifications herein. Similar numerals throughout the several views of the drawings refer to similar parts of our invention.

We attain the objects and advantages of our invention by the device illustrated in the accompanying drawings, in which: t

Figure l is a top plan view of our device showing it installed in a cross-section of a door with portions cut away to show the mechanism;

Figure 2 is a front plan view of the inner door handle;

Figure 3 is a cross-section along the lines 3-3 of Figure 1;

Figure 4 is the same view as shown in Figure 3 with the lock in a different position;

Figure 5 is a sectional view;

Figure 6 is a detail of the plate;

Figure 7 is a detail of the frame of the device; and

Figure 8 is a cross-section of a portion of the locking plate of the device.

Our device is used with a door 11 in a door frame 12. The principle of our device involves a door closure which has an inner door handle 13 with a latch portion 14 adapted to engage the strike bar 15 of a strike plate 16. When the handle 13 is turned approximately 90 degrees, it disengages the strike bar 15 and permits the door 11 to be opened. The entire device is made so that it will be easily installed through a single hole in the door 11.

The device is made in three separate assemblies. There is an outer door knob assembly 17 which comprises a door knob 18 with an integral shank 19. A shaft with square cross-section 20 is swedged into the shank 19. A frame 21 is then placed over the shaft 20 and a stop ferrule 22 is inserted over the shaft inside the frame 21. The stop ferrule 22 has a stop 23, and a spring 24 is provided, one end of which is inserted in an opening 24a in the stop 23 and the other end of which rests on a shoulder 25 of the frame 21. The purpose of the spring is to maintain the stop in normal position against the shoulder 26 of the ice frame 21. A back plate 27 completes the inner door knob assembly.

This entire assembly is placed through the door 11. A lock plate assembly 28 is then placed over the shaft 20 and screwed to the frame 21 by means of screws 29. The various parts of the lock plate assembly 28 and their functions will be described hereinbelow.

When the lock plate assembly 28is screwed to the frame 21, the lock becomes securely-affixed to the door. The final step is to attach the inner door handle assembly which comprises the door handle 13 and a set screw 30.

The lock plate assembly 28 is cast around a lock plate 31. The lock plate 31 has thumb or finger portions 32 to permit the person desiring to lock or unlock the door to slide the lock plate up or down. There is a cut-out portion in the central part of the lock plate 33 which has a square end and a circular end. In Figure 3 of the drawings, the lock plate has been moved up so that the square end 33a of the opening 33 is in substantial relation with the shaft 20. This prevents the shaft 20 from being rotated. It will be seen that where the shaft 20 cannot be rotated, the door handle 13 remains locked in a horizontal position and engages the strike bar 15. The door 11 is locked into the frame 12. e

In Figure 4 of the drawings, the lock plate is moved down so that the shaft 20 is within the circular portion 33b of the opening 33. The shaft 20 is then permitted to rotate and the user may turn either the inner handle 13 or the outer door knob 18 to disengage the latch portion 14 from the strike bar 15 and thereby open the door. Stops 34 and 35 have been provided on the lock plate 31 to cooperate with a ball bearing 36 to maintain the lock plate 31 in either locked or open position. The ball bearing 36 is forced against the stops 34 and 35 by means of a spring 37.

While we have described the preferred form of our invention, there may be other forms in which our invention may be embodied without leaving the scope of the invention and we do not want to be limited to the exact details as set forth herein but wish to be protected for all constructions within the limitations of the claim following.

Wherefore, we claim:

A closure fastener for a swinging door comprising an outer doorknob assembly, a lock plate assembly, and an inner door handle asesmbly: the said outer doorknob assembly having a frame adapted to fit within a bore in the door, a knob rotatably attached to the said frame; a shaft fixed to the said knob and extending through the said frame and through and beyond the said bore in the door, a stop ferrule non-rotatably mounted on the said shaft and within the said frame having a stop extending radially therefrom and spaced between shoulders fixed within the said frame, a helical spring positioned around the said stop ferrule with one end of the spring anchored in the stop of the stop ferrule and the other end of the said helical spring engaging one of the said shoulders so that the spring will exert force against the shoulder which it engages and force the stop against the other shoulder when the closure fastener is in normal latching position, said lock plate assembly having a lock frame positioned around the said shaft, a lock plate slideably secured within the said lock frame having a finger operating portion the said look plate to maintain the round and square openings of the lock plate in position in' relation to the -swinging door to hold the said assemblies together.
