TITLE: DOOR HANDLE AND LATCH
This invention relates to a combination door latch operator and handle assembly for a door, preferably the primary door of a dwelling.
BACKGROUND AND SUMMARY OF THE INVENTION
It usually requires two separate motions to open a door. A button or lever or knob of some description must be operated to retract the latch, and the door handle must be pulled to swing the door to open position. It is difficult to perform the two operations simultaneously and so usually the door latch is retracted first and then the door is pulled open.
Sometimes two hands are required.
In accordance with the present invention, the combination door latch operator and handle assembly can be operated in one single step or motion. The actuator for the door latch is in a position such that it will be squeezed simultaneously with the gripping of the door handle and when thus squeezed will unlatch the door during the pull on the handle to open the door. Preferably the handle has a hand grip portion which is spaced outwardly from the door and the actuator for the door latch is on the side of the hand grip portion facing the door. When this hand grip portion is pulled, a pull is also applied on the actuating portion of the actuator so that 2 ~
in the one motion of pulling the door open, the latch is simultaneously released.
It is a primary object of this invention to provide a door latch operator and handle assembly having a conveniently located and specially designed actuator for releasing the door latch at the same time that the door is pulled to open position, as described above. Other objects are to provide a door latch operator and handle assembly which is rugged, durable and easy to operate, and of a relatively simple construction capable of being inexpensively manufactured.
Other objects, features and advantages of the invention will become more apparent as the following description proceeds, especially when considered with the accompanying drawings.

DETAILED DESCRIPTION
Referring now more particularly to the drawings,there is shown a combination door latch operator and handle assembly 10 comprising a one piece handle 12 having a top mounting portion 14, a bottom mounting portion 16, and an outwardly curved hand grip portion 18 extending between and integrally connected to the top and bottom mounting portions 14 and 16. The handle assembly 10 is shown mounted in vertical position on the outer face 20 of the outer door panel 22 of door D. Fasteners 24 secure the top mounting portion 14 to the outer face 20. Any suitable means may be provided for securing the bottom mounting portion 16 to the outer face 20. In this position, the hand . 3 grip portion 18 is disposed in a vertical plane and is ~paced outwardly from the outer face 20 of the door.
A latch operator 25 includes an elongated horizontal rod 26 which extends through an opening ~8 in the outer door panel 22 and through an opening 30 in the inner door panel 32.
One end of rod 26 terminates in a chamber 34 in the top mounting portion 14 and has a socket 36 secured thereto. The socket 36 is mounted for horizontal sliding movement on an extension 38 of a cylinder 40. The cylinder 40 is xotatably mounted in an opening 42 in the top mounting portion 14~ A compression coil spring 44 in the chamber 34 is compressed between the outer face 20 of the outer door panel 22 and an annular flange 46 on the socket 36, normally urging the rod to the right in Figure 2 to its retracted position.
On the inner side of the door and mounted on the inner face 48 of the inner door panel 32 is a latch and lock bolt housing 50 which is secured in position by the same fasteners 24 which secure the top mounting portion 14 to the door. A latch 52 is pi~otally mounted in housing 50 on a pin 54 and is normally urged by a spring 55 to the position shown in Figure 6 in which it engages a keeper (not shown) in the frame for the door to retain the door in the closed position. The latch 52 may be retracted to disengage the keeper and permit the door to ~ ~3~9 be swung to open position by a hand-operated lever 56 on the inner side of the door. Lever 56 is pivoted to housing 50 and has an arm 57 engageable with a projection 58 on the latch.
When the lever 56 is pivoted counter-clockwise in Figure 6, the arm 57 engages the projection 58 to retract the latch.
The latch 56 may also be retracted from the outer side of the door. Thus the rod 26 extends into the housing 50 and its end S9 is adapted to engage a tab 60 on lever 56 when the rod is moved left to the Figure 3 position to thereby swing lever 56 counter-clockwise and retract the latch. The rod is also capable of moving the lock bolt 61 between retracted and extended positions when rotated by a key 62 inserted in the cylinder 40, but the operation of the lock bolt forms no part of this invention.
Further details of the operation of the latch and the bolt may be seen in my own prior patents Nos.4,520,539, 4,552,393 and 4,576,405, the subject matter of which is incorporated herein by reference.
The rod is, as previously stated, normally held in the retracted position of Figure 2 in which the latch 52 is allowed to remain in its latching position shown in Figure 6 where it engages the keeper to retain the door closed. The rod 2~54~
is moved to the Figure 3 position against the action of the compression coil spring 44 by an actuator 63. The actuator 63 is in form of an elongated lever which is mounted for pivotal movement intermediate its ends on a horizontal pin 64 carried by the top mounting portion 14. The lever has an arm 66 which extends into the chamber 34. An opening 68 in the arm 66 near the pivot pin 64 clears the bottom part 69 of the top mounting portion 14. Near its upper end the arm 66 has an enlarged opening 70 through which freely extends the cylinder extension 38. The arm 66 extends between the back wall 72 of the chamber 34 and the flange 46 on the socket 36.
The lever also has an downwardly extending arm 74 which is curved as shown to generally match the contour of the hand grip portion 18.
It will be noted that the upper part of the hand grip portion 18 and the lower part of the mounting portion 14 have a continuous groove 76 in which the intermediate pivoted portion and lower arm 74 of the lever 63 are free to move. The pivot pin 64 extends across the upper horizontal portion of the groove.
The lower portion of the groove extends into the hand grip portion 14 lengthwise thereof and provides a recess 77 generally matches the shape of the lower lever arm 74.
2 ~ 3 ~
Normally the lever is in the position shown in Figures 1 and 2 under the influence of the compression spring 44. In this position, the lower arm 74 is positioned somewhat inwardly of the hand grip portion but in a position to be pulled or squeezed when the hand grip portion is grasped to pull the door open.
When the hand grip portion 18 is squeezed by a hand which also envelops the lower lever arm 74, the squeezing and outward pulling on the lower lever arm causes the lever 63 to be pivoted to the Figure 3 position in which the lower lever arm 74 is at least partly withdrawn into the recess 77 and the upper lever arm 66 pushes the socket 36 and rod 26 to the left as in Figure 3, unlatching the door. Thus with the single squeezing and/or pulling motion on the hand grip portion 18, the door latch actuator or lever 63 is also operated to extend rod 26 and release the latch.

DETAILED DESCRIPTION
Referring now more particularly to the drawings,there is shown a combination door latch operator and handle assembly 10 comprising a one piece handle 12 having a top mounting portion 14, a bottom mounting portion 16, and an outwardly curved hand grip portion 18 extending between and integrally connected to the top and bottom mounting portions 14 and 16. The handle assembly 10 is shown mounted in vertical position on the outer face 20 of the outer door panel 22 of door D. Fasteners 24 secure the top mounting portion 14 to the outer face 20. Any suitable means may be provided for securing the bottom mounting portion 16 to the outer face 20. In this position, the hand . 3 grip portion 18 is disposed in a vertical plane and is ~paced outwardly from the outer face 20 of the door.
A latch operator 25 includes an elongated horizontal rod 26 which extends through an opening ~8 in the outer door panel 22 and through an opening 30 in the inner door panel 32.
One end of rod 26 terminates in a chamber 34 in the top mounting portion 14 and has a socket 36 secured thereto. The socket 36 is mounted for horizontal sliding movement on an extension 38 of a cylinder 40. The cylinder 40 is xotatably mounted in an opening 42 in the top mounting portion 14~ A compression coil spring 44 in the chamber 34 is compressed between the outer face 20 of the outer door panel 22 and an annular flange 46 on the socket 36, normally urging the rod to the right in Figure 2 to its retracted position.
On the inner side of the door and mounted on the inner face 48 of the inner door panel 32 is a latch and lock bolt housing 50 which is secured in position by the same fasteners 24 which secure the top mounting portion 14 to the door. A latch 52 is pi~otally mounted in housing 50 on a pin 54 and is normally urged by a spring 55 to the position shown in Figure 6 in which it engages a keeper (not shown) in the frame for the door to retain the door in the closed position. The latch 52 may be retracted to disengage the keeper and permit the door to ~ ~3~9 be swung to open position by a hand-operated lever 56 on the inner side of the door. Lever 56 is pivoted to housing 50 and has an arm 57 engageable with a projection 58 on the latch.
When the lever 56 is pivoted counter-clockwise in Figure 6, the arm 57 engages the projection 58 to retract the latch.
The latch 56 may also be retracted from the outer side of the door. Thus the rod 26 extends into the housing 50 and its end S9 is adapted to engage a tab 60 on lever 56 when the rod is moved left to the Figure 3 position to thereby swing lever 56 counter-clockwise and retract the latch. The rod is also capable of moving the lock bolt 61 between retracted and extended positions when rotated by a key 62 inserted in the cylinder 40, but the operation of the lock bolt forms no part of this invention.
Further details of the operation of the latch and the bolt may be seen in my own prior patents Nos.4,520,539, 4,552,393 and 4,576,405, the subject matter of which is incorporated herein by reference.
The rod is, as previously stated, normally held in the retracted position of Figure 2 in which the latch 52 is allowed to remain in its latching position shown in Figure 6 where it engages the keeper to retain the door closed. The rod 2~54~
is moved to the Figure 3 position against the action of the compression coil spring 44 by an actuator 63. The actuator 63 is in form of an elongated lever which is mounted for pivotal movement intermediate its ends on a horizontal pin 64 carried by the top mounting portion 14. The lever has an arm 66 which extends into the chamber 34. An opening 68 in the arm 66 near the pivot pin 64 clears the bottom part 69 of the top mounting portion 14. Near its upper end the arm 66 has an enlarged opening 70 through which freely extends the cylinder extension 38. The arm 66 extends between the back wall 72 of the chamber 34 and the flange 46 on the socket 36.
The lever also has an downwardly extending arm 74 which is curved as shown to generally match the contour of the hand grip portion 18.
It will be noted that the upper part of the hand grip portion 18 and the lower part of the mounting portion 14 have a continuous groove 76 in which the intermediate pivoted portion and lower arm 74 of the lever 63 are free to move. The pivot pin 64 extends across the upper horizontal portion of the groove.
The lower portion of the groove extends into the hand grip portion 14 lengthwise thereof and provides a recess 77 generally matches the shape of the lower lever arm 74.
2 ~ 3 ~
Normally the lever is in the position shown in Figures 1 and 2 under the influence of the compression spring 44. In this position, the lower arm 74 is positioned somewhat inwardly of the hand grip portion but in a position to be pulled or squeezed when the hand grip portion is grasped to pull the door open.
When the hand grip portion 18 is squeezed by a hand which also envelops the lower lever arm 74, the squeezing and outward pulling on the lower lever arm causes the lever 63 to be pivoted to the Figure 3 position in which the lower lever arm 74 is at least partly withdrawn into the recess 77 and the upper lever arm 66 pushes the socket 36 and rod 26 to the left as in Figure 3, unlatching the door. Thus with the single squeezing and/or pulling motion on the hand grip portion 18, the door latch actuator or lever 63 is also operated to extend rod 26 and release the latch.
