The present disclosure generally relates to door position sensing and specifically to door position sensing in mortise locks.
Conventional lock assemblies determine the status of the position of the door regarding whether the door is in a closed state or an open state is determined based on a door positioning feature. Conventional lock assemblies include a door position sensor that is positioned on a printed circuit board assembly (PCBA) that is installed in the lock assembly as well as a magnet that is installed between the strike and the door frame. The magnetometer then detects the magnetic field generated by the magnet when the door is in the closed position and fails to detect the magnetic field of the magnet when the door is in the open position. The position of the door is then indicated as being in the closed position when the magnetic field is detected and as being in the open position when the magnetic field is not detected.
However, mortise lock assemblies include a significant amount of metal as compared to other conventional lock assemblies. The conventional positioning of the magnetometer on the PCBA that is tucked inside the mortise lock assembly fails to detect the magnetic field generated by the magnet installed on the strike when in the closed position due to the significant amount of metal that is positioned between the magnetometer and the magnet. Thus, failing to accurately indicate that the door is in the closed position due to the inability to detect the magnetic field generated by the magnet when in the closed position.
Conventional mortise lock assemblies position the magnetometer in the position typically occupied by the deadbolt to position the door position sensor closer to the magnet installed on the strike to increase the likelihood that the magnetometer detects the magnetic field generated by the magnet when in the closed position. In doing so, the deadbolt is removed from the conventional mortise lock assembly and is no longer available to the user. Further, the door position sensor positioned in the deadbolt location may still not detect the magnetic field generated by the magnet when in the closed position and additional door prep may be required by the user to ensure that the door position sensor detects the magnetic field generated by the magnet when the door position sensor is positioned in the deadbolt location.
Embodiments of the present disclosure relate to positioning a door positioning sensor in a mortise lock assembly such that the door positioning sensor accurately determines whether the door is in the open position or the closed position and in doing so accommodating for the increased amount of metal included in mortise lock assemblies. In an embodiment, a mortise lock assembly that is associated with a door includes an auxiliary latch assembly that is configured to transition between an engaged state and a retracted state. The mortise lock assembly also includes a magnetic field sensing device that is positioned on the auxiliary latch assembly and is configured to detect a magnetic field generated by a magnetic field generating device positioned on a door strike. The magnetic field sensing device positioned on the auxiliary latch assembly is aligned with the magnetic field generating device positioned on the door strike when the door is in a closed position.
In an embodiment, a method determines a position of a door that includes a mortise lock. The mortise lock is transitioned by an auxiliary latch assembly between an engaged state and a retracted state. A magnetic field generated by a magnetic field generating device positioned on a door strike is detected by a magnetic field sensing device that is positioned on the auxiliary latch assembly. The magnetic field sensing device positioned on the auxiliary latch assembly is aligned with the magnetic field generating device positioned on the door strike when the door is in a closed position.
In an embodiment, a mortise lock assembly that is associated with a door includes a main latch assembly that is configured to transition between an engaged state and a retracted lock state. A magnetic field sensing device that is positioned on the main latch assembly is configured to detect a magnetic field generated by a magnetic field generating device positioned on a door strike. The magnetic field sensing device positioned on the main latch assembly is aligned with the magnetic field generating device positioned on the door strike when the door strike is in a closed position.

Mortise Lock Assembly
The mortise lock assembly 100 may be installed in the door 102, which may have a secured/inner side facing a secured/inner environment (e.g., the interior of a building) and unsecured/outer side facing an unsecured/outer environment. In some embodiments, it should be appreciated that the unsecured/outer side may face another secured environment (e.g., secured by virtue of another access control device/system). Additionally, one or more manual actuators such as handles, knobs, or levers (not illustrated) may be coupled to the transmission assembly 116. In operation, the drive assembly 106 moves the catch 108 between a locking position and an unlocking position to define locked and unlocked states of the lock assembly 100. With the catch 108 in the unlocking position, an outer handle is free to rotate, and rotation of the outer handle is transmitted through the transmission assembly 116 to cause retraction of the latch assembly 110. When in the locking position, the catch 108 engages the transmission 116 such that rotation of the outer handle is prevented, and the outer handle is not operable to retract the latch assembly 110.
The auxiliary latch assembly 114 includes an auxiliary latch 118 slidingly mounted to the case 104, a deadlocking member 120 pivotably mounted on a post 122, and a biasing member such as a torsion spring 124 rotationally biasing the auxiliary latch 118 toward the transmission assembly 116. As the door 102 is closed, the auxiliary latch 118 is depressed to a retracted position via contact with the door frame or door strike located at the door frame. As the auxiliary latch 118 retracts, the spring 124 urges the auxiliary latch 118 to a blocking position, wherein the free end of the auxiliary latch 118 is aligned with the main latch bolt 112. In this position, the auxiliary latch 118 prevents the main latch bolt 112 from being forced inwardly by an externally-applied force, thereby deadlocking the main latch bolt 112.
The lock assembly 100 also includes a controller 130 which controls operation of the drive assembly 106 to move the catch 108 between the locking and unlocking positions. The controller 130 may be in communication with a user interface 132, such as a keypad or credential reader which may be mounted on or adjacent to the door 102. The controller 130 may additionally, or alternatively, be in communication with a control system 134. In operation, the controller 130 may maintain the lock assembly 100 in the locked state, and may operate the drive assembly to move the catch 108 to the unlocked position in response to an authorized unlock command from the user interface 132 and/or the control system 134. The lock assembly 100 further includes an aperture 136 configured to contain a key cylinder (not shown). A screw assembly 138 engages the key cylinder to hold the cylinder within the aperture 136.
The controller 130 may determine a position of the door based on a magnetic field sensing device that detects a magnetic field generated by a magnetic field generating device. The magnetic field sensing device may be positioned in the lock assembly 100 such that the magnetic field sensing device detects the magnetic field generated by the magnetic field generating device positioned on a door strike. The magnetic field generating device positioned on the door strike may enable the magnetic field generating device to be positioned in a stationary position relative to the door 102 such that the magnetic field generating device remains stationary positioned while the door 102 rotates between the open state and the closed state. The magnetic field generating device may be a permanent magnet, an electromagnet, and/or any type of magnetic field generating device that generates a magnetic field that may be detected by the magnetic field sensing device that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the disclosure.
The magnetic field sensing device may be positioned in the lock assembly 100 such that the magnetic field sensing device changes position as the door 102 changes position. The magnetic field sensing device may also be positioned in the lock assembly 100 such that the magnetic field sensing device detects the magnetic field generated by the magnetic field generating device positioned on the door strike when the door 102 is in the closed position. The magnetic field sensing device may detect the magnetic field generated by the magnetic field generating device when the door 102 is in the closed position due to the magnetic field sensing device being within a sufficient range of the magnetic field generating device to detect the magnetic field generated by the magnetic field generating device when the door 102 is in the closed position. As the door 102 transitions from the closed position to the open position, the magnetic field sensing device may no longer be within sufficient range to detect the magnetic field generated by the magnetic field generating device and thus fails to detect the magnetic field when the door 102 transitions to the open position.
The controller 130 may determine the position of the door 102 based on whether the magnetic field sensing device detects the magnetic field generated by the magnetic field generating device. The magnetic field sensing device may indicate to the controller 130 that the magnetic field sensing device is detecting the magnetic field generated by the magnetic field generating device. As noted above, the magnetic field sensing device may detect the magnetic field generated by the magnetic field generating device when the magnetic field sensing device is within sufficient range to detect the magnetic field. Due to the positioning of the magnetic field sensing device on the lock assembly 100, the magnetic field sensing device may detect the magnetic field when the door 102 is in the closed position. Thus, the controller 130 may determine that the door 102 is in the closed position when the magnetic field sensing device indicates that the magnetic field sensing device detects the magnetic field generated by the magnetic field generating device.
The magnetic field sensing device may also indicate to the controller 130 that the magnetic field sensing device is no longer detecting the magnetic field generated by the magnetic field generating device. As noted above, the magnetic field sensing device may no longer detect the magnetic field generated by the magnetic field generating device when the magnetic field sensing device is no longer within sufficient range to detect the magnetic field. Due to the positioning of the magnetic field sensing device on the lock assembly 100, the magnetic field sensing device may no longer detect the magnetic field when the door 102 is in the open position. Thus, the controller 130 may determine that the door 102 is in the open position when the magnetic field sensing device indicates that magnetic field sensing device no longer detects the magnetic field generated by the magnetic field generating device. The magnetic field sensing device may be a magnetometer, a reed switch, a hall effect sensor, and/or any other type of magnetic field sensing device that is capable of detecting the magnetic field generated by the magnetic field generating device when the door 102 is in the closed position that will be apparent to those skilled in the relevant art(s) without departing from the spirit and scope of the disclosure.
In conventional mortise lock assemblies, the magnetic field sensing device is positioned on the PCBA of the controller 130 and the magnetic field generating device 172 is positioned on the door strike as shown in
The interference generated by the metal of the lock assembly 100 prevents the magnetic field sensing device conventionally positioned on the controller 130 from adequately detecting the magnetic field generated by the magnetic field generating device 172 positioned on the door strike. In doing so, the magnetic field sensing device conventionally positioned on the controller 130 fails to detect the magnetic field generated by the magnetic field generating device 172 when in the closed position and thus fails to indicate to the controller 130 that the door 102 is in the closed position. Rather, the magnetic field sensing device incorrectly indicates to the controller 130 that the door 102 is in the open position due to the magnetic field sensing device failing to detect the magnetic field generated by the magnetic field generating device 172 despite the door being in the closed position due to the interference caused by the metal of the lock assembly 100. Thus, the controller 130 may incorrectly determine that the door 102 is in the open position when the door 102 is actually in the closed position due to the magnetic field sensing device conventionally positioned on the controller 130 failing to detect the magnetic field generated by the magnetic field generating device 172 as positioned on the door strike due to the interference caused by the metal of the lock assembly 100.
In other conventional mortise lock assemblies, the auxiliary latch assembly 114 is removed from the mortise lock assembly 100 and the magnetic field sensing device is positioned where the auxiliary latch assembly 114 would have been positioned. The magnetic field generating device is then conventionally positioned on the door strike such that the magnetic field generating device is aligned with the magnetic field sensing device positioned in the space previously occupied by the auxiliary latch assembly 114. In doing so, the metal of the lock assembly that was previously in between the magnetic field sensing device conventionally positioned on the controller 130 and the magnetic field generating device 172 positioned on the door strike is no longer so. The conventional positioning of the magnetic field sensing device in the position of the auxiliary latch assembly 114 and the conventional positioning of the magnetic field generating device on the door strike as aligned with the magnetic field sensing device enables the magnetic field sensing device to adequately detect the magnetic field generated by the magnetic field sensing device when the door 102 is in the closed position.
However, such conventional positioning of the magnetic field sensing device in the position of the auxiliary latch assembly 114 prevents the lock assembly 100 from having an auxiliary latch feature and thus prevents the user from having the extra protection of an auxiliary latch 118 in addition to the main latch bolt 112. Further, the conventional positioning of the magnetic field sensing device on the door strike such that the magnetic field sensing device is aligned with the previous position of the auxiliary latch assembly 114 where the magnetic field sensing device is conventionally positioned requires additional door prep by the installer. In doing so, the installer is required to drill additional holes in the door strike and to adequately secure the magnetic field generating device in the door strike such that the magnetic field generating device is adequately aligned with the previous position of the auxiliary latch assembly and thereby aligned with the magnetic field sensing device positioned where the auxiliary latch assembly 114 was previously positioned. The additional door prep prevents the installer from simply removing older mortise lock assemblies and replacing with the mortise lock assembly 100.
In order to include the auxiliary latch assembly 114 while positioning the magnetic field sensing device and the magnetic field generating device to prevent interference from the metal in conventional mortise lock assemblies, the magnetic field sensing device is positioned above the auxiliary latch assembly 114 and the magnetic field generating device is positioned higher on the door strike to have the magnetic field generating device align with the magnetic field sensing device. In doing so, the metal of the lock assembly that was previously in between the magnetic field sensing device conventionally positioned on the controller 130 and the magnetic field generating device 172 positioned on the door strike is no longer so while allowing the capabilities of the auxiliary latch assembly 114 to be utilized. The conventional positioning of the magnetic field sensing device in the position above the auxiliary latch assembly 114 and the conventional positioning of the magnetic field generating device higher on the door strike as aligned with the magnetic field sensing device enables the magnetic field sensing device to adequately detect the magnetic field generated by the magnetic field sensing device when the door 102 is in the closed position while also enabling the utilization of the auxiliary latch assembly 114.
However, such conventional positioning of the magnetic field sensing device above the position of the auxiliary latch assembly 114 as well as the conventional positioning of the magnetic field sensing device higher on the door strike such that the magnetic field sensing device is aligned with the position of the magnetic field sensing device above the auxiliary latch assembly 114 requires additional door prep by the installer. In doing so, the installer is not only required to drill additional holes in the door strike to adequately secure the magnetic field generating device in the door strike but to also drill additional holes in the lock assembly 100 such that the magnetic field generating device is adequately aligned with the position of the magnetic field sensing device above the auxiliary latch assembly 114 and thereby aligned with the magnetic field sensing device. The additional door prep prevents the installer from simply removing older mortise lock assemblies and replacing with the mortise lock assembly 100. Further, this conventional positioning also prevents the use of a deadbolt function in the lock, thus restricting the user from the additional security of a deadbolt option.
In order to prevent interference from the metal of the of the mortise lock assembly 100 from impacting the magnetic field sensing device from adequately detecting the magnetic field generated by the magnetic field generating device 172 when the door 102 is in the closed position as well as providing the auxiliary latch assembly 114 within the mortise lock assembly 100, and eliminating any unnecessary door prep by the installers, the magnetic field sensing device may be positioned on the auxiliary latch assembly 114 and/or the latch assembly 110. In doing so, the magnetic field sensing device may be positioned such that the magnetic field sensing device is able to adequately detect the magnetic field generating device 172 as positioned on the door strike as shown in
Auxiliary Latch Assembly
The plunger 140 includes a magnetic field sensing device 148, which is configured to detect a magnetic field provided by a magnetic field generating device 172, such as a permanent magnet, as further described with respect to
The plunger 140, in some embodiments, includes a cavity of a sufficient size to accommodate the magnetic field sensing device 148. The cavity of the plunger 140, in various embodiments, is formed by removing a sufficient amount of material from a preformed single-piece plunger. In other embodiments, the cavity may be formed by a plunger 140 made of multiple parts that, when assembled, provide or define the cavity.
The magnetic field sensing device 148 may detect the magnetic field generated by the magnetic field generating device 172 when the magnetic field sensing device 148 that is positioned on the auxiliary latch assembly 114 is aligned with the magnetic field generating device 172 when the door 102 is in the closed position. The magnetic field sensing device 148 is within range of the magnetic field generating device 172 to detect the magnetic field when the magnetic field sensing device 148 is aligned with the magnetic field generating device 172 when the door 102 is in the closed position. As shown in
The magnetic field sensing device 148 may fail to detect the magnetic field generated by the magnetic field generating device 172 positioned on the door strike assembly 152 when the magnetic field sensing device 148 that is positioned on the auxiliary latch 118 is not aligned with the magnetic field generating device 172 when the door 102 is in the open position. The magnetic field sensing device 148 is not within range of the magnetic field generating device 172 to detect the magnetic field when the magnetic field sensing device 148 is not aligned with the magnetic field generating device 172 when the door 102 is in the open position. As the door 102 is transitioned into the open position, the magnetic field sensing device 148 positioned on the auxiliary latch 118 may no longer be within sufficient distance of the magnetic field generating device 172 positioned on the door strike assembly 152 to adequately detect the magnetic field generated by the magnetic field generating device 172.
The magnetic field sensing device 148 may indicate that the door 102 is in the closed position when the magnetic field sensing device 148 positioned on the auxiliary latch 118 is aligned with the magnetic field generating device 172 positioned on the door strike assembly 152 when the door 102 is in the closed position. The magnetic field sensing device 148 may indicate that the door 102 is in the open position when the magnetic field sensing device 148 positioned on the auxiliary latch 118 is not aligned with the magnetic field generating device 172 on the door strike assembly 152 when the door 102 is in the open position.
The magnetic field sensing device 148 may indicate to the controller 130 that the door 102 is in the closed position when the magnetic field sensing device 148 positioned on the auxiliary latch 118 is aligned with the magnetic field generating device 172 positioned on the door strike assembly 152 when the door is in the closed position. In doing so, the controller 130 may indicate to the user that the door 102 is in the closed position. For example, the controller 130 may generate an indicator displayed on the user interface 132 that provides a visual indication of the state of the door 102 with respect to the door frame. In this example, the controller 130 may generate the indicator as displayed on the user interface 132 that the door 102 is in the closed position with respect to the door frame such that the user may easily identify that the door 102 is in the closed position.
The magnetic field sensing device 148 may indicate to the controller 130 that the door 102 is in the open position when the magnetic field sensing device 148 is positioned on the auxiliary latch 118 is not aligned with the magnetic field generating device 172 on the door strike assembly 152 when the door is in the open position. In doing so, the controller 130 may indicate to the user that the door 102 is in the open position. For example, the controller 130 may generate the indicator as displayed on the user interface 132 that the door 102 is in the open position with respect to the door frame such that the user may easily identify that the door 102 is in the open position.
The magnetic field sensing device 148 may detect the magnetic field generated by the magnetic field generating device 172 when the auxiliary latch assembly 114 transitions the auxiliary latch 118 from a retracted position to an engaged position. The magnetic field sensing device 148 may be positioned on the auxiliary latch assembly 114 such that the magnetic field sensing device 148 may be aligned with the magnetic field generating device 172 when the auxiliary latch 118 is in the engaged position and the retracted position when the door 102 is in the closed position.
As shown in
In an embodiment, the controller 130 may be coupled to the magnetic field sensing device 148 via a set of wires 150 that move with the arm 142 when the arm 142 moves. The set of wires 150 may slide with the arm 142 as the auxiliary latch assembly 114 moves between the retracted position and the engaged position thereby maintaining an electrical connection between the controller 130 and the magnetic field sensing device 148. The maintaining of the electrical connection between the controller 130 and the magnetic field sensing device 148 may enable the magnetic field sensing device 148 to continuously indicate to the controller 130 the status of the door 102 regarding whether the door 102 is in the open position or the closed position. In doing so, the controller 130 may continuously display to the user the current status of the door 102 regarding whether the door 102 is in the open position or the closed position.
In an embodiment, the controller 130 may be coupled to the magnetic field sensing device via an electrical contact such that the electrical contact moves with the arm 142 when the arm 142 moves. The electrical contact may slide with the arm 142 as the auxiliary latch assembly 114 moves between the retracted position and the engaged position thereby maintaining an electrical connection between the controller 130 and the magnetic field sensing device 148. The maintaining of the electrical connection between the controller 130 and the magnetic field sensing device 148 may enable the magnetic field sensing device 148 to continuously indicate to the controller 130 the status of the door 102 regarding whether the door 102 is in the open position or the closed position. In doing so, the controller 130 may continuously display to the user the current status of the door 102 regarding whether the door 102 is in the open position or the closed position.
The mortise lock assembly 100 is configured to engage a door strike assembly 152 illustrated in
By locating the magnet 172 in the door strike, no additional door preparation is required, since the magnet is hidden behind the door strike plate 154. Consequently, the magnet 172 is completely hidden for better aesthetics. As can be seen in
As further illustrated in
Main Latch Assembly
In this embodiment, the main latch bolt 200 includes a magnetic field sensing device 210, which is configured to detect a magnetic field provided by one or more magnetic field generating devices, such as a permanent magnet or magnets, as further described with respect to
In this embodiment, the main latch bolt 200 includes a cavity having a sufficient size to accommodate the magnetic field sensing device 210. The cavity of the main latch bolt 200, in various embodiments, is formed by removing a sufficient amount of material from a preformed single-piece main latch. In other embodiments, the cavity may be formed in the main latch bolt 200 by multiple parts that, when assembled, provide the cavity.
The magnetic field sensing device 210 may detect the magnetic field generated by the magnetic field generating devices 242 or 240 when the magnetic field sensing device 210 that is positioned on the main latch bolt 210 is aligned with the magnetic field generating devices 242 or 240 when the door 102 is in the closed position. The positioning of the two magnetic field generating devices 242 and 240 enables the magnetic field sensing device 210 to detect the magnetic field generated field generated by the magnetic field generating device 242 or 240 based on the magnetic field generating device 242 or 240 that is positioned closer to the magnetic field sensing device 210 based on the positioning of the main latch bolt 210. In doing so, an installer may rotate the main latch bolt 180 degrees and the magnetic field sensing device 210 may still adequately detect the magnetic field generated by the magnetic field generating device 242 or 240. The magnetic field sensing device 210 is within range of the magnetic field generating devices 242 or 240 to detect the magnetic field when the magnetic field sensing device 172 is aligned with the magnetic field generating device 242 or 240 when the door 102 is in the closed position. As shown in
The magnetic field sensing device 210 may fail to detect the magnetic field generated by the magnetic field generating devices 240 or 242 positioned on the door strike assembly 220 when the magnetic field sensing device 210 that is positioned on the main latch bolt 200 is not aligned with the magnetic field generating devices 242 or 240 when the door 102 is in the open position. The magnetic field sensing device 210 is not within range of the magnetic field generating devices 240 or 242 to detect the magnetic field when the magnetic field sensing device 210 is not aligned with the magnetic field generating devices 240 or 242 when the door 102 is in the open position. As the door 102 is transitioned into the open position, the magnetic field sensing device 210 positioned on the main latch bolt 200 may no longer be within sufficient distance of the magnetic field generating device 240 or 242 positioned on the door strike assembly 220 to adequately detect the magnetic field generated by the magnetic field generating device 240 or 242.
The magnetic field sensing device 210 may indicate that the door 102 is in the closed position when the magnetic field sensing device 210 positioned on the main latch bolt 200 is aligned with the magnetic field generating devices 240 or 242 positioned on the door strike assembly 220 when the door 102 is in the closed position. The magnetic field sensing device 210 may indicate that the door 102 is in the open position when the magnetic field sensing device 210 positioned on the main latch bolt 200 is not aligned with the magnetic field generating devices 240 or 242 on the door strike assembly 220 when the door 102 is in the open position.
The magnetic field sensing device 210 may indicate to the controller 130 that the door 102 is in the closed position when the magnetic field sensing device 210 positioned on the main latch bolt 200 is aligned with the magnetic field generating devices 240 or 242 positioned on the door strike assembly 220 when the door 102 is in the closed position. In doing so, the controller 130 may indicate to the user that the door 102 is in the closed position. For example, the controller 130 may generate an indicator displayed on the user interface 132 that provides a visual indication of the state of the door 102 with respect to the door frame. In this example, the controller 130 may generate the indicator as displayed on the user interface 132 that the door 102 is in the closed position with respect to the door frame such that the user may easily identify that the door 102 is in the closed position.
The magnetic field sensing device 210 may indicate to the controller 130 that the door 102 is in the open position when the magnetic field sensing device 210 is positioned on the main latch bolt 200 is not aligned with the magnetic field generating devices 240 or 242 on the door strike assembly 220 when the door 102 is in the open position. In doing so, the controller 130 may indicate to the user that the door 102 is in the open position. For example, the controller 130 may generate the indicator as displayed on the user interface 132 that the door 102 is in the open position with respect to the door frame such that the user may easily identify that the door 102 is in the open position.
The magnetic field sensing device 210 may detect the magnetic field generated by the magnetic field generating devices 240 or 242 when the main latch bolt 200 transitions from a retracted to an engaged position. The magnetic field sensing device 210 may be positioned on the main latch bolt 200 such that the magnetic field sensing device 210 may be aligned with the magnetic field generating devices 240 or 242 when the main latch bolt 200 is in the engaged position and the retracted position when the door 102 is in the closed position.
As shown in
In an embodiment, the controller 130 may be coupled to the magnetic field sensing device 210 via a set of wires 214 that move with the rod 212 when the rod 212 moves. The set of wires 214 may slide with the rod 212 as the main latch bolt 200 moves between the retracted position and the engaged position thereby maintaining an electrical connection between the controller 130 and the magnetic field sensing device 210. The maintaining of the electrical connection between the controller 130 and the magnetic field sensing device 210 may enable the magnetic field sensing device 210 to continuously indicate to the controller 130 the status of the door 102 regarding whether the door 102 is in the open position or the closed position. In doing so, the controller 130 may continuously display to the user the current status of the door 102 regarding whether the door 102 is in the open position or the closed position.
In an embodiment, the controller 130 may be coupled to the magnetic field sensing device via an electrical contact such that the electrical contact moves with the rod 212 when the rod 212 moves. The electrical contact may slide with the rod 212 as the main latch bolt 200 moves between the retracted position and the engaged position thereby maintaining an electrical connection between the controller 130 and the magnetic field sensing device 210. The maintaining of the electrical connection between the controller 130 and the magnetic field sensing device 210 may enable the magnetic field sensing device 210 to continuously indicate to the controller 130 the status of the door 102 regarding whether the door 102 is in the open position or the closed position. In doing so, the controller 130 may continuously display to the user the current status of the door 102 regarding whether the door 102 is in the open position or the closed position.
In an embodiment, the main latch bolt 200 is configured to engage a door strike assembly 220 as illustrated in
The magnet tray 224 further includes a first magnetic field generating device 240 and a second magnetic field generating device 242, which are held by the magnet tray 224. In some embodiments, the magnet tray 224 includes first and second sleeves each defining a cavity configured to hold the magnets 240 and 242. The magnet tray 224 may be formed of thermoformed plastic material and may be securely held between the strike plate 222 and the magnet housing 226 when assembled and located at the door frame. However, it should be appreciated that the magnet tray 224 may be formed of other materials suitable for the structural and functional aspects of the magnet tray 156 described herein. The door strike housing 226 includes a well 244 configured to receive the latch bolt and deadbolt when engaged from the door lock assembly 100. For example, the magnet tray 224 and the door strike housing 226 may be generated as a single piece, thus the door strike housing 226 may include a feature to hold the magnets 240 and 242.
The magnetic field sensing device 210 may detect a first magnetic field generated by a first magnetic field generating device 242 positioned at a first position on the door strike assembly 220 that is above a first aperture 236 on the magnet tray 224 above where the main latch bolt 200 of the main latch device transitions through when the door 102 transitions from the open state to the closed state. The magnetic field sensing device 210 may detect a second magnetic field generated by a second magnetic field generating device 240 positioned at a second position on the door strike assembly 220 that is below the first aperture 236 on the door strike on the magnet tray 224 where the main latch bolt 200 of the main latch device transitions through when the door 102 transitions from the open state to the closed state.
In an embodiment, the first magnetic field generating device 242 and the second magnetic field generating device 240 may be positioned on the door strike assembly 220 as depicted in
The magnetic field sensing device 210 may be positioned at a first position on the main latch bolt 200. The first position of the magnetic field sensing device 210 on the main latch bolt 200 may be closer to the first magnetic field generating device 240 than the second magnetic field generating device 242 when the main latch bolt 200 is installed in a first position. The first position of the magnetic field sensing device 210 on the main latch bolt 200 may then be closer to the second magnetic field generating device 242 than the first magnetic field generating device 240 when the main latch bolt 200 is rotated 180 degrees and is installed in a second position. Regardless as to whether the main latch bolt 200 is installed in the first position and/or rotated 180 degrees and installed in the second position, the magnetic field generating device 210 installed in the first position on the main latch bolt 200 may within sufficient range to detect the magnetic field generated by the first magnetic field generating device 240 and/or the second magnetic field generating device 242 when the door 102 is in the closed position.
In
The present disclosure provides a door position sensor for a mortise, which in one embodiment, utilizes an existing auxiliary latch or main latch modified to include a magnetic field sensor. No or little additional door preparation time is required as the magnetic field generating device (e.g., a permanent magnet) located in the door strike assembly is located and hidden behind the door strike plate.
In addition to being able to use preexisting locations for a door strike assembly, concerns regarding the gap between the strike assembly and the door lock becomes are reduced during door setup, as the auxiliary latch and therefore the sensor, is located against the door strike plate when the door is closed. No or little additional door preparation time is therefore required. When the main latch is configured to include the magnetic field sensor, concerns regarding the particular door strike material are reduced, because the sensor extends behind the door strike plate and between the magnets when the door is closed. Accordingly, in some embodiments, a stainless steel strike plate may be used.
