This patent disclosure relates generally to an upward acting door system and method and, more particularly, to an upward acting door system and method that is configured to vent a space such as a garage, warehouse or other interior space.
Garages, warehouse spaces and other areas that are enclosed, or at least partially enclosed, by an upward acting door occasionally contain undesirable conditions. For example, the spaces may become too hot, particularly on a hot day and a vehicle is parked in the space. Heat from the engine may be transferred to the space raising the temperature to be hotter than the outside and bringing the temperature in the space to an uncomfortable level.
Other undesirable conditions may include the space containing undesirable substances such as carbon monoxide (CO), smoke, water or other liquid (flooding) and the like. Accordingly, it is desirable to have a system and method for mitigating undesirable conditions that may occur in an enclosed space.
The foregoing needs are met to a great extent by embodiments in accordance with the present disclosure, wherein, in some embodiments includes a door operator. The door operator includes: a controller; a sensor operatively connected to the controller, the sensor configured to detect an undesirable condition and communicate a signal to the controller when the undesirable condition is detected; and a door operatively connected to the controller and the controller is configured to cause the door to move from a closed position to a non-closed position when the controller receives the signal.
In another aspect, the disclosure describes a method of operating a door. The method includes: detecting an undesirable condition with a sensor; communicating with a controller when the undesirable condition is detected by the sensor; and moving the door from a closed position to a non-closed position when the controller receives the signal.
In another aspect, the disclosure describes a door operator. The door operator includes: a controller; a sensor operatively connected to the controller, the sensor configured to detect any one of heat, liquid pooled on a floor, and CO and communicate a signal to the controller when any one of the heat, liquid, and CO is detected; and a door operatively connected to the controller, the controller is configured to cause the door to move from a closed position to an intermediate position between a closed position and a fully opened position and stop at the intermediate position when the controller receives the signal.

Referring initially to
Specifically encrypted RF transmissions emanate from hand held (or vehicle mounted) transmitters 53 representing door commands to the barrier operator 20. Commands can also be transmitted from an interior wall mounted console 32, and/or an exterior wall mounted keyless entry console (not shown). The barrier operator 20 may be similar, for example, to that described in U.S. Pat. No. 6,118,243, issued Sep. 12, 2000 to Reed et al., and incorporated herein by reference for all purposes, but having the hereinafter described additions, modifications and features.
The barrier operator system 1 additionally includes a mechanical drive sub-system 2, the details of which are subsequently described, and generally comprises as its major components, (i) an elongated beam or rail assembly 22 connected at one end 86 to wall 12 and at its opposite end 76 to the barrier operator head unit or housing 26; (ii) a drive assembly 5, which can be a reciprocatingly driven drive belt or chain or a rotatably driven screw drive, supported by the rail assembly 22, and (iii) a carriage 50 operably connected to the drive assembly 5. The carriage 50 is disconnectably engageable with an arm 24 which, in turn, is firmly connected to the door 10. Accordingly, motor 28, under control of the barrier operator 20, drives the belt, chain or rotatable screw in one direction or the other, consequently transporting the carriage 50 to respectively raise (open) or lower (close) the door 10. A compression spring and trained cables assembly (not shown) is connected with the door 10 so as to aid the opening and closing of the garage door 10, in the manner well known to those of ordinary skill in the art.
The wall console 32 is supported on one of the internal sidewalls 34 and enables communication with the barrier operator 20 to provide user-instituted instructions to the controller 30. These instructions are initiated by the depression of different buttons on the console initiating signal communications to the barrier operator 20 respectively representing, for example, door movement commands, work light instructions, and vacation lock mode (set or release). Additional details regarding this operation are subsequently described. The signal communications from console 32 are transmitted to the barrier operator either by way of hardwire conductor means 36, as shown, or alternatively by wireless communication. In similar manner, a keyless entry console (not shown) is in wired or wireless communication with the barrier operator 20 and similarly enables user-instructed instructions to the controller 30.
The barrier operator system 1 illustrated in
In some embodiments, and as shown in
The sensor 60 may be used to detect an undesirable condition such as the presence of too much heat, CO, smoke, or other undesirable condition. For example, there may be a threshold amount of heat, CO, smoke or other undesirable condition that the controller 30 may permit but when the threshold amount of an undesirable condition is detected, the controller 30 will take action. In some embodiments, a user may program how what the threshold is. In some embodiments the threshold may be pre-set at time of manufacture. Different thresholds may exist for different substances or conditions.
Actions the controller 30 may take when an undesirable condition is detected may include causing the door 10 to move from a closed position to an open position or at least a partially open position. By opening the door 10, heat, CO, water, smoke, or other undesired condition may be mitigated by venting or draining out the at least partially opened door 10. In some embodiments, the door 10 may only open a few inches to allow venting or draining and yet maintain security of the space 54 enclosed by the door 10 (such as, for example a garage, warehouse, or other space) by not being open enough to allow a person to enter the space 54. In some embodiments, a user may program the barrier operator system 1 to move have the door 10 move to specific position when an undesirable condition is detected. In some embodiments, the door 10 position may be pre-set at time of manufacture. The position the door 10 is moved to may vary depending upon what type of undesirable condition is detected.
Optionally, the controller 30 may take different actions and/or additional actions to partially opening the door 10. For example, the controller 30 may operate a venting system 48 which may be wall mounted, as shown in
A liquid sensor 64 can detect the presence of water or other liquid in the space 54 enclosed by the door 10. A user may select the height from the floor 18 (see
In some embodiments, there is an inside water sensor 64 located inside the space 54 enclosed by the garage door 10 and an outside water sensor 58 both operatively connected to the controller 30. Further, there may be both in inside heat sensor 62 and outside heat sensor 66. In embodiments where there are both inside 62, 64 and outside sensors 58 and 66, the controller 30 may compare readings from the both the inside 62, 64 and outside sensor 58, 66 to ensure that the liquid level and/or heat reading are not greater outside than inside. If the outside sensors 58 and 66 detect a higher reading of a undesirable condition outside than inside the controller 30 will not cause the door 10 to move to an open or partially open system even if the inside sensors 62, 64 detect undesirable conditions in excess of a threshold amount. It will be appreciated that the door 10 is not moved to an open or partially opened position in such instances because there would be no venting of the undesirable condition. Rather, in such cases, opening the door 10 would exacerbate the undesirable condition. Likewise, the CO sensor 68 and other sensors 69 may also operate in inside and outside pairs similar to as described above.
Optionally, the barrier operator system 1 may include ventilation systems 48,49 and or a drainage system 52. The ventilation systems 48, 49 and/ or drainage system 52 are operatively connected to the controller 30. The ventilation systems may be door mounted 49 or wall mounted 48 as described above with respect to
In some embodiments, the barrier operator system may interface with a home automation system 70 (such as but not limited to Amazon Alexia, Google home, etc.). The home automation system 70 is operatively connected to the controller 30 and may be connected wirelessly or by wire. The home automation system 70 may optionally be connected to the drive assembly 5, the drainage systems 52, and the ventilation systems 48, 49 and may operate and/or share data them. Optionally, a home alarm system 72 may be operatively connected to the controller 30 and/or the drive assembly 5 and may operate or control and/or share data with them. In some embodiments, the home automation system 70, the alarm system 72 and the controller 30 may share data with each other.
In some embodiments, if the controller 30 receives a signal(s) indicative of high levels of CO (as to exceed a high level CO threshold which may be programmed by a user or preset at the manufacturer) and/or high levels of smoke (as to exceed a high level smoke threshold which may be programmed by a user or preset at the manufacturer) the controller 30 will send a notification signal to an external system 56 such as local emergency services, a remote monitoring system or other external system. Optionally, the controller 30 may send a notification signal to the alarm system 72 and/or home automation system 70 to alert the occupants of the building in which the space 54 is located so they leave the building, check on the space 54 or otherwise take appropriate action. If a rapid increase in heat and/or smoke is detected by the system, the external system 56, alarm system 72 and/or home automation system 70 may be sent a notification signal as discussed above. Further, in the case of a rapid increase in heat and/or smoke a signal may be sent by the controller 30 to close the door 10.
While the disclosure has been described in terms of exemplary aspects, those skilled in the art will recognize that the disclosure can be practiced with modifications in the spirit and scope of the appended claims. These examples given above are merely illustrative and are not meant to be an exhaustive list of all possible designs, aspects, applications or modifications of the disclosure.
