Detailed Description of the Embodiments [0025] In the following description, functionally similar parts carry the same reference numerals between different embodiments. The drawings are intended to be schematic, and dimensions, scale and/or angles may not be determined accurately from them unless otherwise stated.

[0026] Within the statement of invention, description and claims, unless otherwise stated, the upward and downward directions refer to the orientation of a latch when mounted onto a substantially vertical surface. Axial refers to the principal, normally substantially vertical axis of the latch. Radial refers to a direction substantially orthogonal to the axial direction, but does not necessarily imply that the latch is circular or cylindrical.

[0027] Within the statement of invention, description and claims, unless otherwise stated, the terms fence, panel, post are intended to have equivalent meaning.

[0028] Within the statement of invention, description and claims, unless otherwise stated, the terms mounting means, bracket, fixture are intended to have equivalent meaning.

[0029] Within the statement of invention, description and claims, unless otherwise stated, the terms latch assembly, lock assembly, [0030] Within the statement of invention, description and claims, unless otherwise stated, the term movable barrier includes, for example, a hatch, gate, door, skylight or window, i.e. a member suitable for closing or opening an aperture, but not limited to the pivotal or direction of movement. For example, the member may pivot or slides horizontally and/or vertically.

[0031] Although the description discloses the latch is mounted on the post and the striker is mounted on the gate, in alternative embodiments this may be reversed, i.e. the latch may be mounted on the gate and the striker may be mounted on the post.

[0032] Figures 1 to 3 are schematic front views of a gate 10 for closing an opening in a fence 12. As shown in Figure 1, the gate 10 is in a closed position and is secured with a prior art latch 14a in a latched condition.

[0033] Figure 2 illustrates the gate 10 in the closed position with the latch 14a in an unlatched condition, whereby a release mechanism 18 of the latch 14a is actuated to release a striker 16 in order to unlatch the latch 14a. Figure 3 illustrates the gate 10 in an open position.

[0034] Figures 4 to 6 illustrate the gate 10 secured with a prior art alarm enabled latch 14b for closing the opening in the fence 12. As shown in Figure 4, the gate 10 is in the closed position with the alarm enabled latch 14b in a latched condition.

[0035] Figure 5 illustrates the gate 10 in the closed position with the alarm enabled latch 14b in an unlatched condition, whereby the release mechanism 18 of the latch 14b is actuated to release the striker 16 in order to unlatch the latch 14b. As illustrated in Figure 5, in the unlatch condition the alarm enabled latch 14b releases an audible and/or visual alarm 20.

[0036] In another scenario, it can be envisaged that the alarm enabled latch 14b will alarm when the gate 10 is closed and the latch 14b visually appears to be latched, but is actually unlatched, for example, if a foreign body or matter preventing the latching mechanism of the latch 14b from positive engagement.

[0037] Figure 6 illustrates the gate 10 in an open position and the alarm enabled latch 14b continues to release the audible and/or visual alarm 20 as the alarm enabled latch 14b still remains unlatched. The audible and/or visual alarm 20 may be silenced once the gate 10 is closed and the alarm enabled latch 14b is in the latched condition. Alternatively, the alarm enabled latch 14b may be provided with a mute switch to mute the audible and/or visual alarm 20.

[0038] Figure 7 is a schematic illustration of a first embodiment of a system 100 for relaying the unlatched condition of a wireless enabled latch 140 to a user according to the present invention. As shown in Figure 7, the wireless enabled latch 140 comprises a wireless transmitter for communicating the unlatched condition of the latch 140 via a first wireless protocol to a base unit 24. Advantageously, in order for the wireless enabled latch 140 to conserve power, the latch 140 may be configured to sense either the unlatch or latched condition, i.e. so the wireless transmitter is operated on demand. Advantageously, the latch 140 may be configured to only transmit a wireless signal 22 and not to receive wireless signals. It can be envisaged that receiving of wireless signals requires the latch 140 to be continually powered in a standby mode, thus consuming power.

[0039] Advantageously, the wireless enabled latch 140 may be configured to transmit status information of its power supply on a timed basis. For example, the wireless enabled latch 140 may transmit the power supply status to the base unit 24 twice a day.

[0040] The wireless transmitter of each latch 140 may communicate with the base unit 24 via a first wireless protocol, such as radio frequency (RF). For example, the radio frequency may by a 433MHz radio frequency or other radio frequencies and bandwidth. The radio frequencies can be licence-free frequencies.

[0041] Figure 8 is a detailed view of the base unit 24. As illustrated, the base unit 24 may comprise an antenna 26, user interface 28 and speaker 30, which will be described in more detail below. The base unit 24 may be a portable unit or a stationary unit, whereby the base unit 24 can be powered by mains or a portable power source. As shown in Figure 9, the base unit 24 may be a portable unit supplied with a docking station 32 for charging the power supply of the base unit 24.

[0042] During use, the when the gate 10 in the closed position and the wireless enabled latch 140 is in an unlatched condition, the wireless enabled latch 140 releases a local audible and/or visual alarm 20 and sends the wireless signal 22 to the base unit 24. The base unit 24 converts the signal 22 into an audible and/or visual alarm via the user interface 28 and speaker 30 to notify the user that the wireless enabled latch 140 is unlatched. As the gate 10 is opened, the wireless enabled latch 140 continues to release the audible and/or visual alarm 20 and sends the signal 22 to base unit 24 as the wireless enabled latch 140 remains unlatched. Advantageously, the user interface 28 and speaker 30 may replicate the audible and/or visual alarm 20 of the wireless enabled latch 140.

[0043] During use it can envisaged that the wireless enabled latch 140 may be mounted on a gate 10 located at some distance from the user where the audible and/or visual alarm 20 of the wireless enabled latch 140 may not be visible or heard. In such case, the base unit 24 may be located nearer the user where the base unit 24 will notify the user that the wireless enabled latch 140 is unlatched.

[0044] Figure 10 is a schematic illustration of the system 100 where a plurality of wireless enabled latches 140, 140a are provided, wherein each wireless enabled latch 140, 140a transmits their respective wireless signal 22, 22a to the base unit 24. Advantageously, the wireless signal 22, 22a of each wireless enabled latch 140, 140a is encoded, encrypted or has its own signal identifier to prevent interference of signals between multiple wireless enabled latches. It can be envisaged, that one wireless enabled latch 140 would be used to secure a pool gate, whilst the other wireless enabled latch 140a would be used to secure a garden perimeter gate.

[0045] As previously described, the user interface 28 of the base unit 24 may comprise a touch screen interface, visual indicators, buttons or a combination of visual indicators and buttons to provide a visual indication on the status of each wireless enabled latch 140, 140a and/or to configure the base unit 24 to operate with multiple wireless enabled latches 140, 140a.

[0046] The user interface 28 would provide status of each wireless enabled latch 140, 140a, for example, power supply status, latched/unlatched status and connected / paired status etc. Advantageously, the user interface 28 may replicate the interface of each wireless enabled latch 140, 140a. In addition, the user interface 28 may allow the user to mute the audible alarm from the speaker 30, and in such case the visual alarm may continue to alert the user as a safety measure. Alternatively, the user interface 28 may allow the user to selectively mute or operate different and various alarm functions, such as visual alarms, audible alarms, haptic alarms or vibrational alarm.

[0047] Figure 11 is a schematic illustration of a second embodiment of the system 200 whereby the base unit 24 further communicates the status of each wireless enabled latch 140 to a remote device 34. In this embodiment, the remote device 34 may be a mobile phone or a remote control. The mobile phone 34 may be a smart device configurable to control or operate the base unit 24. Advantageously, the mobile phone 34 may contain a display that replicates the status of each wireless enabled latch 140 and/or the base unit 24.

[0048] As illustrated in Figure 11, a communication link 36 between the remote device 34 and the base unit 24 may be a bi-directional communication link to enable the remote device 34 to control or operate the base unit 24.

[0049] Figure 12 is a schematic illustration of a third embodiment of the system 300 whereby an intermediate remotely located device 38 may be provided between the remote device 34 and the base unit 24. In this embodiment, the intermediate remotely located device 38 may be a bridging unit, for example, a modem, router, or a local area network. Advantageously, the bridging unit 38 may wirelessly enabled, for example, a wireless modem, wireless router, or a wireless local area network.

[0050] As illustrated in Figure 12, the communication link 36 between the remote device 34 and the bridging unit 38 may be a bi-direction communication link, and a communication link 36 between the bridging unit 38 and the base unit 24 may be a bi-direction communication link to enable the remote device 34 to control or operate the base unit 24.

[0051] Figure 13 is a schematic illustration of a fourth embodiment of the system 400 whereby the base unit 24 further communicates the status of each wireless enabled latch 140 to a home network 42. In this embodiment, the home network 42 may be a home security network. The home security network 42 may relay status of each wireless enabled latch 140 and/or base unit to an off-site network 46.

[0052] As illustrated in Figure 13, a communication link 348 between the off-site network 46 and the home security network 42 may be a bi-direction communication link, and a communication link 44 between the home security network 42 and the base unit 24 may be a bi-direction communication link to enable the off-site network 46 to control or operate the base unit 24.

[0053] Advantageously, the bi-direction communication link 36, 40, 44 between the base unit 24 and at the remote device 34, intermediate remotely located device 38 and home network 42 may operate on a second wireless protocol, such Wi-Fi, Zig BEE, Z Wave, 3G, 4G, GSM, radio frequencies, or Bluetooth etc. Advantageously, the use of two different wireless protocols to minimise interference of signals.
