Wireless Deadbolt Door Lock

Abstract

A wireless deadbolt door lock is an electric dock lock that can be powered and controlled through wireless means. This is accomplished using an electric deadbolt door lock body containing a Dual Position Latching Solenoid (DPLS) to move a deadbolt plunger in a reciprocating linear motion, between a withdrawn deadbolt position and a locking deadbolt position, protruding out from the electric deadbolt door lock body. The DPLS is controlled by an energy efficient bi-stable permanent magnet activation system (BSPMAS), which can be wirelessly controlled. A wireless charging station between the door frame and the door can be used to charge batteries or capacitors to power the BSPMAS. A mechanical release/locking device and electrical mechanical switches are also provided for unlocking or locking the deadbolt door lock when a wireless device is unavailable.

In FIG. 2, the housing 12b is firmly attached to the housing 12a and affixes to the door as in prior art door locks; housing 12a and 12b contain the deadbolt plunger 14, plunger guide/spacer 15, shaft 16, door locking spring 18, spring compressor 19, and DPLS 20; the shaft 16 is free to move through the end of the housing 12a and the deadbolt plunger 14 is free to move through the housing 12b; the deadbolt plunger 14 is free to move though the plunger guide/spacer 15; the spring compressor 19 is firmly attached to the shaft 16 to compress or allow decompression of the door locking spring 18 as the shaft 16 moves; and the shaft 16 moves with the operation of the DPLS 20 as shown in FIG. 3.

[0029] In FIG. 2, provision for keeping the plunger guide/spacer 15 from leaving the inside of the electric door locking body 10 is done by extending the housing 12b. It is understood that other provisions for keeping the plunger guide/spacer 15 from leaving the inside of the electric deadbolt door lock body 10 can be done without taken from the intent of the present invention.

[0030] It is understood that the electric deadbolt door lock body 10 of FIG. 2 does not need the door locking spring 18 and the spring compressor 19 to function when the magnetic force of the DPLS is higher than the resistive forces on the shaft 16, deadbolt plunger 14, and moveable magnetic core 28.

[0031] FIG. 3 is a drawing to illustrate one version of a DPLS 20 that can be used in the electric deadbolt door lock body 10 of FIG. 2, comprising a magnetic housing 22, control coils 24a and 24b, permanent magnet 26, and moveable magnetic core 28, where the shaft 16 of FIG. 2 is firming attached to the moveable magnetic core 28. In FIG. 3a, the moveable magnetic core 28 is magnetically latched to the left end of the magnetic housing 22, having moved the shaft 16 to the left as indicated by the arrow. In FIG. 3a, the moveable magnetic core 28 is magnetically latched to the right end of the magnetic housing 22, having moved the shaft 16 to the right as indicated by the arrow.

[0032] It is understood that in FIG. 3 the gap provides the movement distance of the moveable magnetic core 28 and should be matched to the expected movement distance of the deadbolt plunger 14 of FIG. 1.

[0033] In FIG. 3, the DPLS 20 is similar to U.S. Pat. No. 3,022,450 with the coils 24a-b composed of multiple coils for use with the BSPMAS 60 in the present invention, as is discussed in U.S. Pat. No. 9,343,216.

[0034] As shown in FIG. 3, provision for the Power Input to the control coils are provided in a central top location. It is understood that other provisions for the power lines in different locations can be done without taken from the intent of the present invention.

[0035] FIG. 4 is a drawing to illustrate the frame locking mechanism 30 of the present invention, comprising a housing 31a and 31b, a frame locking spring 32, and a frame locking plunger 34 having a portion extruding into the spring for alignment. In FIG. 4, provision for keeping the frame locking plunger 34 from leaving the inside of the frame locking mechanism 30 is done by extending the housing portion 31b; the motion of the frame locking spring 32 and the frame locking plunger 34 allow for differences in the movement distance of the deadbolt plunger 14 in FIG. 1 due to differences in door/frame assemblies to assure that the moveable magnetic core 28 of FIG. 3 firmly latches to the housing 22 of FIG. 3.

[0036] It is understood that other provisions for keeping the frame locking plunger 34 from leaving the inside of the frame locking mechanism 30 can be done without taken from the intent of the present invention.

[0037] It is understood that the door locking spring 18 in FIG. 2 and the frame locking spring 32 in FIG. 4 provide a mating force pair to overcome motion fiction in the present invention, and to help move the moveable magnetic core 28 of FIG. 3 to move across the gap of FIG. 3, where the door locking spring 18 and frame locking spring 32 exchange stored energies and attain stored energy from the magnetic force on the moveable magnetic core 28 of the DPLS of FIG. 3.

[0038] In reference to FIGS. 1-4 with the moveable magnetic core 28 in the position shown in FIG. 3a, when a current is applied to a first control coil 24a or 24b in the DPLS 20 of FIG. 3 to cause the magnetic flux from the permanent magnet 26 to be directed toward the right side of the magnetic housing 22, the moveable magnetic core 28 will be magnetically attracted to the right side of the magnetic housing 22. Whereby, the moveable magnetic core 28 moves (with the aid of the spring force from the frame locking spring 32 on the frame locking plunger 34 in the frame locking mechanism 30) from the position in FIG. 3a to the position in FIG. 3b, carrying the shaft 16 with it, placing the deadbolt plunger 14 in the electric deadbolt door lock body 10 from the position in FIG. 1 to the position in FIG. 2. Whereby, the deadbolt plunger 14 is pulled out of the frame locking mechanism 30 allowing the frame locking spring 32 to decompress by pushing the frame locking plunger 34 from the position in FIG. 1 to the position in FIG. 4, and the movement of the spring compressor 19 with the shaft 16 compresses the door locking spring 18 as shown in FIG. 2; placing the present invention in an unlocked deadbolt position.

[0039] Reversely, with the moveable magnetic core 28 in the position shown in FIG. 3b, when a current is applied to a second control coil 24b or 24a in the DPLS 20 of FIG. 3 to cause the magnetic flux from the permanent magnet 26 to be directed toward the left side of the magnetic housing 22, the moveable magnetic core 28 will be magnetically attracted to the left side of the magnetic housing 22. Whereby, the moveable magnetic core 28 moves (with the aid of the spring force of door locking spring 18 on the spring compressor 19) from the position in FIG. 3b to the position in FIG. 3a, carrying the shaft 16 with it, placing the deadbolt plunger 14 in the electric deadbolt door lock body 10 from the position in FIG. 2 to the position in FIG. 1. Whereby, the deadbolt plunger 14 is pushed into the frame locking mechanism 30 against the frame locking plunger 34 to compress the frame locking spring 32 by moving the frame locking plunger 34 from the position in FIG. 4 to the position in FIG. 2, and the movement of the spring compressor 19 with the shaft 16 allows the door locking spring 18 to decompress as shown in FIG. 1, placing the present invention in a locked deadbolt position.

[0040] FIG. 5 is a drawing to illustrate one embodiment of the mechanical release/locking device 40 that can be used in the present invention, comprising a housing 12c firmly attached to the housing 12a of the electric door locking body 10, a force member 42, and a pivot portion 44 that is firmly attached to the force member 42. The pivot portion 44 is attached (not shown) to the housing 12c in a manner that allows it to freely rotate and the force member 42 is attached (not shown) to the shaft 16 in a manner that pulls or pushes the shaft 16 when the force member 42 is rotated.

[0041] It is understood that other mechanical release/locking mechanism can be used without taken from the intent of the present invention.

[0042] In reference to FIGS. 1-5, and when a levering force, say from a lever type door handle attached to the pivot portion 44, causes the force member 42 to rotate in one direction, the shaft 16 is pulled outward toward the mechanical release/locking device 40 to pull the moveable magnetic core 28 in the DPLS 20 of FIG. 3 (with the aid of the spring force from the frame locking spring 32 on the frame locking plunger 34 in the frame locking mechanism 30) from the position shown in FIG. 3a to the position in FIG. 3b, placing the deadbolt plunger 14 in the electric deadbolt door lock body 10 from the position in FIG. 1 to the position in FIG. 2. Whereby, the deadbolt plunger 14 is pulled out of the frame locking mechanism 30 allowing the frame locking spring 32 to decompress by pushing the frame locking plunger 34 from the position in FIG. 1 to the position in FIG. 4, placing the present invention in an unlocked deadbolt position. Resulting in the compression of the door locking spring 18 in FIG. 2.

[0043] Reversely, when the levering force causes the force member 42 to rotate in the reverse direction, the shaft 16 is pushed inward toward the mechanical release/locking device 40 to push the moveable magnetic core 28 in the DPLS 20 of FIG. 3 (with the aid of the spring force from the door locking spring 18 on the spring compressor 19) from the position shown in FIG. 3b to the position in FIG. 3a, placing the deadbolt plunger 14 in the electric deadbolt door lock body 10 from the position in FIG. 2 to the position in FIG. 1. Whereby, the deadbolt plunger 14 is pushed into the frame locking mechanism 30 against the frame locking plunger 34 to compress the frame locking spring 32 by moving the frame locking plunger 34 from the position in FIG. 4 to the position in FIG. 2, placing the present invention in a locked deadbolt position. Resulting in the decompression of the door locking spring 18 in FIG. 2.

[0044] FIG. 6 illustrates one wireless charging station 50 known in the art of wireless power charging that can be used in the present invention to wirelessly charge batteries or capacitors for operation of the present invention. The wireless charging station 50 shown is an inductive charger (also known as wireless charging or cordless charging) as is known in the art of wireless power charging. The wireless charging station 50 is composed of a transmitter 50a and receiver 50b, which uses an electromagnetic field to transmit energy between the transmitter 50a and receiver 50b through electromagnetic induction. Whereby, they form a wireless charging station, when the door is closed.

[0045] In FIG. 6, the transmitter 50a attains Input Power from the Power Management System of the home or building, which could simply be a power outlet. The power goes to a Power Transmitter Unit coupled to a capacitor C1 and an inductor L1, which transmits energy outward. In FIG. 6, the receiver 50b has a Power Receiving Unit coupled to a capacitor C2 and an inductor L2, which receives the Transmitted Energy from the inductor L1 across the Door/Frame Gap. The Power Receiving Unit conditions the attained energy to the proper voltage needed to charge the batteries or capacitors in the present invention.

[0046] It is understood that capacitors, especially supercapacitors, will be better suited for the present invention as batteries may need periodic changed.

[0047] It is understood that other wireless power systems maybe used without taken from the intent of the present invention.

[0048] FIG. 7 illustrates a modification of FIG. 2 from the Energy Efficient Bi-Stable Permanent Magnet Actuation System (BSPMAS 60) of U.S. Pat. No. # 9,343,216 for operation of the DPLS 20 in the present invention, comprising: a power source 61, which is the battery or capacitor being charged by the wireless charging station 50 in FIG. 6; a voltage conditioner 62; a wireless control module 63; three switches 64a-c; a capacitor 65; and a voltage sensor 66.

[0049] Operation of the BSPMAS 60 of FIG. 7 begins by closing power source switch 64a by wireless control module 63 to allow power from the power source 61 to inner the voltage conditioner 62. The voltage conditioner 62 conditions the voltage of the power source and passages a low current 67a to the storage capacitor 65 until the operation voltage of the DPLS 20 is reached. That is, the voltage on the capacitor 65 will rise with charge from the voltage conditioner 62 until the wireless control module 63 senses the operation voltage through sensor 66. When the wireless control module 63 receives an input from an operator, by means of an outside wireless device, one of the switches 64b or 64c is activated to send a pulsed current 67b to one of the control coils 24a or 24b of the DPLS 20 of FIG. 3 to either lock or unlock the electric deadbolt door lock.

[0050] It is understood that the outside wireless device can be any wireless device that can communicate with the wireless control module 63.

[0051] It is understood that the switch 64a may not be needed when the BSPMAS 60 is design for very low or zero power drain between operations.

[0052] It is understood that the home or building's power management system may contain a wireless control module that can talk to the wireless control 63 of the present invention to periodically turn off the power to the transmitter 50a when the wireless control 63 of the present invention indicates that the batteries or capacitors are fully charged.

[0053] FIG. 8 illustrates optional lock/unlock mechanical switches 70a and 70b, where FIG. 8 is a portion of FIG. 7 to show the placement of the mechanisms 70a and 70b. As shown, mechanical switch 70a allow the switch 64b to be bypassed and mechanical switch 70b allow the switch 64c to be bypassed.

[0054] It is understood that the switches 70a and 70b should be momentary switches to prevent excessive power loss and be on the inside of the door to allow lock or release of the deadbolt when a wireless device is unavailable.

[0055] It is understood that similar mechanical switches 70a and 70b can be placed on the outside of the door if used with a security method (key or etc.) to prevent unwanted entry.

[0056] FIG. 9 illustrates optional switches for operating the DPLS with a portable device containing a BSPMAS 60 similar to that shown FIG. 7, where FIG. 9 is a portion of FIG.7 to show the placement of the switches 80a-d, where switches 80c-d act like switches 64b-c to provide current flow through the control coils 24a-b to the ground in the portable device. In FIG. 9, the connection to switches 80a-d must be such that the switch 80a is opened to turned off the deadbolt lock power to prevent charging or discharging of the capacitor 65 in FIG. 7, the switch 80b is closed to provide power from the portable device. It is understood that the switches 80a-d could be access through one of more electrical connector on the door.
