DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

In describing the preferred embodiment of the present invention, reference will be made herein to FIGS. 1-5 of the drawings in which like numerals refer to like features of the invention.

The present invention allows controlled access into a building or enclosed area while minimally impacting the appearance and structure of the entrance door. An embodiment of the invention is employed in an all glass entranceway or other entryway where aesthetics are important and would be highly valued by architects. Access through the door would be given to a user having a proper RFID card or other wireless signal transmitting device in their possession.

The reader for the RFID or other wireless reader device may be integrated into the handle or pull used to open and close the door. In the embodiment shown in FIGS. 1 and 2, an all glass entryway comprises glass walls or glass side panes 70, 72 within which are mounted glass doors 50, 50′. In one example, one door 50 may include the wireless door entry system while the other door 50′ is operable by a manual securing system, or the doors 50, 50′ may both be operable by a door controller in communication with the wireless reader device. An elongated door pull or other type of handle includes a hollow tube main body 30, an integrated, battery powered wireless reader 10 and a handle connector portion 40 secured to the exterior of glass door 50 adjacent swinging free edge 52. The door handle or pull as shown in the cutaway view of FIG. 2 may be a hollow cylindrical or other shape tube 30 with end caps 30a, 30b secured to the hollow tube. The handle connector portion 40 may be perpendicular to the tube or handle 30 to secure to the face of the door 40 and space the handle from the surface of door 50 a distance sufficient to enable users to wrap their hands around and grasp the tube 30. The wireless reader 10 as shown may be disposed inside the hollow handle at a mid-point between upper and lower ends 30a, 30b and includes a bezel which may be secured, e.g., by snapping in a compression fit, so that face 10′ is disposed on the surface of the hollow tube 30. The face 10′ in the embodiment shown is of cylindrical configuration to match the tube 30. The face 10′ configuration may be shaped to conform to the exterior of other tube configurations, e.g., oval, or flat for rectangular or square. Alternatively, the wireless reader 10 may be disposed in the edge of the top end 30a of the door pull 30 if door pull end is located at a convenient height for users, making it less visible in the door pull. The wireless reader assembly 10, 10′, and 20 may also be constructed in a one piece design to be located on the top end of the handle. Placement of the card reader 10 inside the hollow tube eliminates the visibility of a separate card reader in an all glass entryway, such as that shown in FIG. 1. For longer door pulls where the top of the pull is not easily accessible, the reader may be disposed in a central or lower portion of the pull and wired to a top edge that may secure the battery 20. The door pull may alternately include a rechargeable battery including a charging system such as a solar cell or induction charger.

The wireless RFID or other device reader is shown disposed entirely within tubular handle 30 in FIG. 3. The reader 10 includes within housing 18 controller circuitry 16 in communication with an RFID transmitter/receiver located in face 10′, and a transmitting antenna 14 for Wi-Fi or other radio signal. In the case of a passive RFID card or other device 90, transmitter/receiver 10′ sends an inductive interrogator signal 102, which then causes an authentication reply signal 104 to be emitted from RFID device 90. Controller 16 determines whether signal 104 is from an authorized device, in which case it may cause signal 106 to be transmitted to a door controller or other device.

A plurality of conductors 12 electrically connect the battery 20 to the card reader 10. As shown in FIG. 5, battery 20 may be located inside a battery pack 22 that is configured with an end cap 32 of tube 30. Alternately, a solar charger 24 located on a surface of handle 30 may charge a rechargeable battery to power the card reader 10, so less maintenance would be required.

Door 50 as shown includes a wirelessly controlled door latching system, as shown in FIG. 4, which provides an uncoupling/releasing securing mechanism. Door 50 includes a sill or rail 58, at the top or bottom of the door, having a latching device 56 with a retractable latchbolt 57 extending therefrom into strike 60, located in the door frame 62 or floor adjacent latching device 56. The door may be unlocked either by use of a latch mechanism 56 which retracts latchbolt 57 in response to a command from latch controller 70 or an electric strike mechanism 60 which opens the strike in response to a command from strike controller 80.

In use, users would place their unique RFID card or other wireless signal transmitting device 90 near the card reader face 10′ where it may be powered by an inductive signal from the reader 10 to emit proper credentials from the antenna in the form of a signal 104. Alternately, the unique device 90 may be self-powered to send out a signal 104, or may not need power to relay the card code signal to the reader 10. This signal 104 from device 90 would be sent to a Wi-Fi or other wireless hub which is tied into the access control system, disposed in or otherwise in communication with latch controller 70 and/or strike controller 80. The access control system determines if the signal is one that is permitted access to that opening. If access is granted, the access control system unlocks the door securing mechanisms (strike 60 or latching device 56) allowing the user to enter.

A method for using the system may include presenting the wireless transmitter device 90 in the vicinity of the reader 10 in the door handle and wirelessly transmitting credentials from the wireless transmitting device. Upon verification of the credentials transmitted from the wireless transmitting device 90, a signal is sent from the reader 10 to the door controller or latching device 56 to uncouple or release the securing mechanism, permitting the door to open. The door controller and securing mechanism may be disposed on a top or bottom rail of the door and the card reader is capable of sending a signal to the door controller to allow the door controller to activate or deactivate the securing mechanism. Alternately, the door controller and securing mechanism may be disposed in the door a door frame encompassing the door with a strike disposed in the rail on the door and the card reader sends the signal to the door controller to allow the door controller to activate or deactivate the securing mechanism.

Thus, the present invention provides a system for allowing access through a glass door using a wireless identification key and receiver, the receiver located within a door handle pull on the door and a wireless identification receiver within a door pull or handle of a door. The present invention also provides a system for allowing access through a glass door using a wireless identification key and receiver, including a circuit located in the handle of the door capable of receiving an identification code from a key a user and transmitting a signal to a door locking mechanism. The present invention also provides a door or building access system and a method of using the door or building access system which allows a user wireless access through a glass door with the transmitter/receiver circuit located on or within the door handle secured to the glass pane of the door so the wireless access circuit is not visible on or within the glass panes of the door. The present invention also provides the wireless access circuit not being visible on or within glass side panels of the doors.
