Abstract
A electronic combination lock includes a rotatable shaft which interacts with a bolt to
permit locking and release. A solenoid armature shaft interacts with a rotatable shaft to
inhibit or permit rotation of the shaft. A first battery is located in a housing for operating
the solenoid. Terminals are provided in the front of the housing for the lock to permit
connection with a second battery to provide power to the lock as necessary. A pistol grip
permits rotation of the shaft when the solenoid armature is free of the shaft.
Description
- This application relates to the european patent application of the present Applicant being filed coterminously with the present application. Such application is entitled "ELECTROMECHANICAL LOCK WITH DIFFERENT SEQUENCES OF OPERATION IN RELATION TO KEYING IN DIFFERENT ACCESS CODES", European Patent Application No.
- The contents of that application are incorporated by reference herein.
- This invention relates to a combination lock, which is electrically or battery operable. Such locks can be for use on safes or on doors. A problem that exists with different battery and electrically operated combination locks is often caused by low battery power or a power failure. Such low power can cause difficulty in operating a electrical components such as a solenoid often associated with such a lock.
- This invention is directed to providing an improved mechanism for operating an electrical or battery operated combination lock in a manner which makes it less dependent on the conventional electrical or battery powering of the lock. The invention is directed to minimize the difficulties with known electrical and battery operated combination locks.
- It is an object of the present invention to disclose and provide an electrical or battery powered combination lock mechanism for secure use to ensure the ability to operate in the event of power failures or low battery conditions associated with the lock.
- This is achieved by carrying out the features disclosed in the main claims. The dependent claims outline preferred forms of embodiment of the invention.
- Generally stated, the present invention includes a lock, which includes a bolt-locking mechanism operable between a bolt-locking and a bolt-release condition through entry of a lock-opening combination by digital input of a predetermined code to operate the locking mechanism. There is also a rotatable shaft with a formation to interact with a solenoid armature such that interaction with the armature prevents rotation of the shaft. When the armature is released, the shaft is rotatable. Rotation of the shaft permits a bolt to move between the locking position and the release condition.
- There is provided a first battery for operating the lock-activating mechanism and. in turn, the armature-activating mechanism. Terminals are provided in a front face of the housing for the lock, the terminals are for connection with conductors such that a supplemental backup battery or the like can be provided to connect with the lock-activating mechanism and, operate the armature-activating mechanism.
- A snap-in battery has protruding terminals from one face to snap into engagement with two terminals provided on the front face of the lock. The terminals are mounted at a location ahead and above of a pistol grip mechanism for rotating the shaft when the armature-activating mechanism is released from the formation on the periphery of the shaft.
- A main battery is located in a battery housing within the lock mechanism which is located and accessible at the rear of a keypad for the lock.
- The invention is further described with reference to the accompanying drawings.
-
- FIG. 1
- is a perspective exploded view showing an electrical combination lock with a front housing keypad input touch-sensitive panel housing for a battery, and a battery for normal location. There is also shown a solenoid armature and rotatable shaft for operation with the bolt. The bolt-receiving area and jam is also shown. This lock would be useful for a safe system or other lockable system.
- FIG. 2
- is a cross-sectional side view of the lock mechanism.
- FIG. 3
- is a perspective view of a lock mechanism showing the snap-in battery.
- A
lock housing 10 includes areceptacle area 11 with awindow portion 12, for receiving akeypad face 13 with a series of numerals and/or alphabetic characters that can provide for the different combination for operating an electronic lock. Behind thekeyboard input face 13, there is a touch-sensitive element 14. which responds to pressure on thekeypad 13. On the keypad, there arecells 15, which correspond tocells 16 on the touch-sensitive pad 14. On thekeypad 13, there are two cutouts, 17 and 18.Cutout 17 is larger thancutout 18. Electrically-conductivecorresponding components sensitive pad 14. In this manner,appropriate terminals battery 23 can be manually applied to touch theterminals - In the sub-housing or
battery housing 24, there is located abattery 25, which can be rechargeable, if necessary. Theterminals 26 from thebattery 25 connect with aspring element 27 that is connected with acable 28 to the touch-pad 14. Theterminals pad 14 are shown through thewire 29. - The
wire 29 is connected to the electronic system andmechanism 30 of the armature-activatingmechanism 31 for activating thearmature 32 to move upwardly and downwardly to engage acam surface 33 of arotatable shaft 34. Aspring 35 can act to cause thearmature 32 to be urged downwardly and/or alternatively, theshaft 32 can be urged downwardly under gravity action. Theshaft 34 engages abolt 35 and then that engages areceptacle slot 36 in ajam 37, which is figuratively shown in FIG. 1. As illustrated, the armature-engaging protruding element engages anaperture 38 in the cam of the rotatable shaft. - In other situations. the armature may engage a different kind of interactive element, for instance a flat face on the cam. The one end of the armature is connected with a
cap element 39 for engaging apistol grip 40. Asuitable receptacle slot 41 is provided, and a screw or stud connector 42 allows for the secure location of the pistol grip with astud 39. When the end of thearmature 32 does not engage theaperture 38, theshaft 34 can be rotated, which, in turn, causes thebolt 35 to move between the released and unreleased positions. Ideally, when thearmature 32 engages theaperture 38, the bolt is in the engaged position in thereceptacle 36 in thejam 37. Movement of the end of thearmature 32 from theaperture 38 permits the rotation of the shaft and removal of the bolt from thereceiving slot 36. - The
keypad 13 includes anaperture 43 for receiving anLED 44, which is connected electrically with the touch-pad 14 so that the operation electrically of the system can be indicated by the LED. The LED and electronics can be programmed so that it flashes in any fashion selectively in any one or more of the conditions of when the system is operable, non-operable, activated to permit unlocking, activated to permit locking, battery flat, or battery operational. - There are many other examples of the invention, each differing from the other in matters of detail only.
- For instance, although the invention is described with reference to an armature that moves physically downwardly to interact with the shaft, other configurations may have the armature move sideways to engage the shaft. There could also be other situations of armature and shaft engagement so that the bolt can be operational by a hand mechanism different from the pistol grip. Suitable electronics can be provided for operating the bolt when the armature is released from/into engagement with the shaft.
- A feature of the invention is the provision externally of terminal ports to permit a backup battery to be used with the lock mechanism in the event that the in-house battery or other electrical supply to the lock mechanism fails or is lower than required.
- The invention is to be determined in terms of the following claims.
