DETAILED DESCRIPTION

[0015] It will be readily understood that the components of the described devices, systems, and methods, as generally described and illustrated in the Figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the described devices, systems, and methods, as represented in the Figures, is not intended to limit the scope of the described devices, systems, and methods, as claimed, but is merely representative of certain examples of presently contemplated embodiments in accordance with the described devices, systems, and methods.

[0016] Automatic opening and closing of sliding windows and sliding doors generally requires planning ahead and use of frames that are designed specifically for automatic sliding doors and automatic sliding windows. However, when automation of an existing installation is desired, a complete replacement of the existing frame is costly and requires more construction skill than the typical homeowner possesses. The devices, systems, and methods disclosed herein disclosed provide solutions to this issue. A motor installed on the sliding segment of the door or window is coupled by a gear to a gear track (as in a rack and pinion). The gear track is attached to one of the horizontal members of the frame. Rotation of the gear walks the gear along the gear track, causing the sliding segment to move from closed to open and back again. This solution is cost effective and requires minimal construction skill.

[0017] Referring now to the Figures, FIG. 1A shows an isometric top-left view 100 of a motorized sliding segment 114 mounted slidably in a frame 102 that may be used in the described devices, systems, and methods. FIG. 1B shows a front isometric view of the frame of FIG. 1A. The frame 102 may be a window frame or a door frame. The frame includes a fixed segment 112, top horizontal member 108, bottom horizontal member 110, left vertical member 104, and right vertical member 106. The track for the sliding segment 114 is offset from the fixed segment 112 so that the sliding segment can open and close. It is appreciated that before the addition of any motor assemblies 116, the sliding segment 114 is manually operated (the sliding segment 114 and frame 102 may be dumb or non-smart devices).

[0018] Motor assemblies 116 are affixed to the top and/or bottom of the left side of the sliding segment 114. Although two motor assemblies 116 are shown in FIG. 1, any number of motor assemblies 116 may be used, including just one as illustrated in FIG. 3. While the left side is identified, it is appreciated that a motor assembly 116 may be affixed to any location on the sliding segment 114 without departing from the scope of the present systems, devices, and methods. Motor assemblies 116 contain a motor and a gear, as described in FIG. 2. Gear tracks 118 are affixed to the top and bottom horizontal members 108 and 110. The gears mesh with the teeth of the gear tracks 118. The motors turn the gears in a first direction, causing the gears to walk along the gear tracks 118, causing the slidable segment 114 to slide towards this vertical member. Rotation the opposite direction walks the gears the other direction, pulling the slidable segment the other direction. In the present instance, the motor assemblies 116 are mirror images of one another, and so the motors turn opposite each other to walk the same direction. In other words, the motors are antiparallel to each other.

[0019] Referring to FIG. 2, FIG. 2 shows a cutaway cross-sectional isometric view 200 of one of the gear tracks 118 of FIG. 1A with its associated gear 202. The gear 202 turns, the teeth engaging the gear track 118. As the gear track 118 is affixed to one of the horizontal members, this forces the slidable segment 114 to slide open or closed.

[0020] Referring now to the Figures, FIG. 3A shows an isometric top-left view 300 of a motorized sliding segment 314 mounted slidably in a frame 302 that may be used in the described devices, systems, and methods. FIG. 3B shows a front isometric view of the frame of FIG. 3A. The frame 302 may be a window frame or a door frame. The frame includes a fixed segment 312, top horizontal member 308, bottom horizontal member 310, left vertical member 304, and right vertical member 306. The track for the sliding segment 314 is offset from the fixed segment 312 so that the sliding segment can open and close.

[0021] Motor assembly 316 is affixed to the bottom of the left side of the sliding segment 314. Motor assembly 316 contains a motor and a gear, as described in FIG. 2. A gear track 318 is affixed to the bottom horizontal member 310. The gear meshes with the teeth of the gear track 318. The motor turns the gear in a first direction, causing the gear to walk along the gear track 318, causing the slidable segment 314 to slide towards this vertical member. Rotation the opposite direction walks the gear the other direction, pulling the slidable segment the other direction.

[0022] In some embodiments, the motor assembly 316 includes a transmission (not shown). The transmission may include one or more gears that convert rotational speed to rotational torque for driving the gear that meshes with the teeth of the gear track. In some cases, the transmission is configured such that the transmission can only be driven by the motor of the motor assembly 316 (cannot be driven by the gear, for example). For instance, the transmission may include a worm gear that may be driven by the motor to drive the gear, but that locks the gear in place when the motor is not spinning (the gear cannot be used to turn the worm gear, for example). Thus, the transmission locks the slidable segment 314 in place in whatever position the slidable segment 314 is in. So in contrast to typical locking mechanisms that only lock a slidable segment when the slidable segment is in a closed position, the transmission locks the gear in place in the teeth of the gear track in whatever place in the gear track that the gear is at. So the slidable segment 314 may be locked in place when the slidable segment 314 is closed as with typical locking mechanisms but could also lock the slidable segment 314 in place when the slidable segment 314 is any degree of partly open or even fully opened. This feature may allow for the slidable segment 314 to be partly opened, while still providing security that the slidable segment 314 cannot be opened further or closed outside of an authorized user's control (when the motor is driven, for example).

[0023] Referring to FIG. 4, FIG. 4 shows a method 400 for automating a slidable segment of a frame using the described devices, systems, and methods. At 401, a gear track is attached to a horizontal member of the frame. At 402, a motor assembly is mounted to a slidable segment, the slidable segment being slidably mounted within the frame. The motor assembly comprises a motor turning a gear. At 403, the teeth of the gear are aligned with tooth spaces of the gear track. The motor has one or more communication systems. At 404, the one or more communication systems communicate with an external remote controller. At 405, the one or more communication systems receive instructions from the external remote controller. At 406, the one or more communication systems generate signals instructing the motor to rotate in a direction. At 407, the one or more communication systems receive signals from the motor regarding a status of the motor. At 408, the one or more communication systems generate a signal informing the external remote controller of the status of the motor.

[0024] Although the operations of method 400 are illustrated as being performed in a particular order, it is understood that the operations of method 400 may be reordered without departing from the scope of the method.

[0025] In some embodiments, the motor includes one or more communication systems. These may include Bluetooth communication chips, Internet Wi-Fi transceivers, network transceivers, a Z-Wave network transceiver, or a combination thereof. In some embodiments, the one or more communication systems communicate with an external remote controller. In some embodiments, the one or more communication systems receive instructions from the external remote controller, generate signals instructing the motor to rotate in a direction, receive signals from the motor regarding a status of the first motor, and generate a signal informing the external remote controller of the status of the motor.

[0026] In some embodiments, the motor has and is powered by one or more batteries. In other embodiments, the motor has and is powered by a power line.

[0027] In some embodiments, the slidable segment is slidably mounted by being between tracks on a top horizontal member of the frame and a bottom horizontal member of the frame, the tracks allowing the slidable frame to freely move side to side.

[0028] In some embodiments, the frame has a latching device that mates to a latching receiver attached to the slidable segment, wherein mating prevents movement of the slidable segment. In some embodiments, the latching receiver comprises a communication device that generates a signal when the latching device is mated and transmits that signal to the motor, wherein the signal deactivates the motor.

[0029] In some embodiments, the first gear track is attached to the horizontal member of the frame by adhesive, screws, nails, or a combination thereof. In some embodiments, the first motor assembly is mounted to the slidable segment by adhesive, screws, nails, or a combination thereof.

[0030] In some embodiments, the first gear track is attached in the track that the slidable segment slides in. In other embodiments, the first gear track is attached adjacent to the track that the slidable segment slides on.
