Abstract

A digital keypad coded entry electronic lock is provided for operating an electronically operated door bolt locking mechanism within a closure or safe. The digital input handle is provided in two parts, with an upper head part positioning the keypad away from a depending handle part. Insertion and removal of an electronic storage battery is facilitated by providing an open rear portion of the handle through which the battery can be inserted or removed without the need for screws, pins or tools.

Claims

1. A digital keypad actuated electronic lock having the keypad associated with a handle exteriorly of a door of a lockable container and with an electronically operated door bolt locking mechanism associated with the door interiorly of the container, said lock comprising:

a handle on an exterior of said container with a handle grip portion depending from a handle head portion;

a digitally operated keypad mounted to said handle head portion allowing an operator to grasp the handle by its grip portion without the operator'"'"'s hand overlying any portions of the keypad.

2. The lock of claim 1 comprising:

A battery housing in said handle having a first battery housing aperture to allow insertion of a battery into said housing without having to open said housing and a second aperture in a portion of said housing overlying an inserted battery to allow digital contact by an operator through said second opening to move the inserted battery out of said housing through said first aperture.

3. A digital keypad actuated electronic lock having the keypad associated with a handle exteriorly of a lockable container and a electronically operated door bolt locking mechanism associated with the door interiorly of the container, said lock comprising:

a battery housing in said handle having a first battery housing aperture to allow insertion of a battery into said housing without having to open said housing and a second aperture in a portion of said housing overlying an inserted battery to allow digital contact by an operator through said second aperture to move the inserted battery out of said housing through said first opening.

4. The lock of claim 3 wherein:

said handle is on an exterior of said container and has a handle grip portion depending from a handle head portion, said housing being within said grip portion.

5. A digital keypad actuated electronic lock having the keypad associated with a handle exteriorly of a door of a lockable container and with an electronically operated door bolt locking mechanism associated with the door interiorly of the container, said lock comprising:

handle means for operating said locking mechanism;

means for mounting said handle on an exterior of said door with a handle grip portion depending from a handle head portion; and

digitally operated electronic keypad means mounted to said handle head portion for entering a locking mechanism opening code and for allowing an operator to grasp the handle by said grip portion without the operator'"'"'s hand overlying any portions of the keypad.

6. The lock of claim 5 comprising:

battery housing means for storing a battery within said handle and having a first battery housing aperture means for allowing insertion of a battery into said housing without having to open said housing and a second battery housing aperture means in a portion of said housing overlying an inserted battery for allowing digital contact by an operator through said second aperture to move the inserted battery out of said housing through said first opening.

7. A safe door unlocking handle assembly having an electronic code for operating an associated electronic door lock keypad entry means, a handle, and a battery and battery housing within the handle which cooperate to facilitate opening of a locked safe door, said handle assembly comprising:

a handle front shell having means for mounting a key pad to a lead portion of said front shell and a handle grip portion depending from said head portion to a fee terminal lower end spaced from said door to facilitate grasping said handle grip portion;

including a key pad mounted code entry means on said handle head portion for entering electronic signals to operate said electronic door lock;

a spindle extending between said handle head portion and said locking mechanism through an aperture in said safe door to facilitate mechanical unlocking of said mechanism by turning of said handle after entry of a correct code has placed the door lock in an unlocked condition;

a rear shell mounted to said front shell closing rear portion of said front shell and providing a battery housing within said handle, said housing having electrical connections for electrically connecting a battery placed in said housing with said code entering means; and

first aperture means for allowing insertion of a battery into said housing without having to open said housing and second aperture means in a portion of said rear shell of said housing overlying an inserted battery for allowing digital contact by an operator through said second aperture to move the inserted battery out of said housing through said first aperture.

8. The safe handle assembly as in claim 7 wherein:

said handle front shell head portion is sufficiently remote from grip portion to facilitate an operator griping said handle grip portion with without engaging said key pad when turning said handle.

9. The safe handle assembly as in claim 7 comprising:

said second aperture therein and means for mounting said rear shell onto said front shell.

10. The safe handle assembly as in claim 7 wherein said electrical connections within said battery housing are supplemented by two conduction areas on the exterior of said handle to which terminals of another battery can be placed to provide an additional power source to recharge a rechargeable battery inserted within said housing.

11. The safe handle assembly as in claim 9 comprising:

a flange member which rests against a front face of the safe door and against which said rear shell mounted is mounted.

12. The safe handle assembly as in claim 7, wherein said handle battery housing includes an upwardly declining rib over which ribs against which said battery is inserted within said housing and which cooperates with said rear shell cover to hold an inserted battery within said housing.

13. The safe handle door unlocking handle assembly as in claim 7 wherein:

said handle has a rear shell having a rear shell head portion at an upper end thereof and a lower battery covering portion;

said rear shell covering portion having a vertically oriented oblong slot thereby providing said second aperture for digital contacting of said battery while the same is within said housing.

14. The handle assembly as in claim 13 wherein said rear shell is not coexitensive with said front shell, a lower end of said rear shell terminating above said front shell to provide a battery entry and retrieval opening between said shells which comprises said first aperture which facilitates insertion and removal from said battery relative said housing without removal of said rear shell on any portion thereof.

15. The handle assembly of claim 7 wherein:

a rib means is provided within said housing against which an inserted battery achieves a snug fit, retaining said battery in said housing until an operator moves said battery, overcoming said snug fit.

16. The handle assembly of claim 15 wherein said rib means is provided within said front shell and has an upwardly declining rib surface facing toward said door.
