The present disclosure relates to gates and gate systems, like for use in the entrance and/or exit of parking garages. More particularly, the instant disclosure relates to a hydraulic lift gate system for use in the entrance and/or exit of parking garages or like structures with a swing gate mechanism to swing open an overhead lift gate system, like an overhead hydraulic lift gate.
Generally speaking, gates, like tilt gates, are often installed in the entrances and/or exits of parking garages or other like structures. Lift gates include a flat panel that tilts as they're lifted upwards to rest flat overhead or near the ceiling. The typical lifting system includes an overhead operator with a motor that drives an arm for lifting the gate. Overhead gate openers are generally commercially used in underground parking garages where space is at a premium. They lift the gate overhead very similar to a typical garage door opener. In this instance the gate may weigh much more than a residential garage door, thus, the operator and hardware are built much heavier to accommodate these loads.
As parking garages have various size openings for the entrance and/or exit, gates and the systems they operate on typically need to be custom designed to fit the desired entrance/exit opening with the desired operating features required or desired by the owner. One problem that has been discovered is the time, effort, and training it takes to install current gates and their lift systems. For example, in addition to the time it takes for the pre-work of designing the gate and the lift system and features, a standard install of a tilt gate and lift system with standard operating features by experienced installers can take a week's worth of time and effort or more to install. As a result, the entrances and exits are either unusable and/or not secured for an undesired lengthy period of time. As one should readily understand, it is clearly desirable to shorten the length of time it takes to install and make the installation of the gates and lifting systems easier.
Another problem that has been discovered is the danger associated with installing current gates and lift systems. The current standard systems have a spring-loaded arm assembly to reduce the force required to raise the gate. This spring-loaded arm assembly is very difficult to initially install onto the gate, as the gate is often times too heavy to be manually lifted. As such, the spring-loaded arm assembly has to be stretched down to reach the gate. This process is very difficult and has been discovered to lead to damage of parts and/or injury to the installers. As such, it is clearly desirable to provide a lift gate system that is easier and safer to install.
Another problem that has been discovered with current lift gate systems is the difficulty in aligning the tracks squarely with the gates. The alignment of the tracks is important for operating the lift gate system properly and/or efficiently. As such, it is clearly desirable to provide a lift gate system that is easier to align the tracks.
Another problem that has been discovered with current lift gate systems is that, to conceal the operator inside the parking garage to prevent tampering and unauthorized access (i.e. the operator must be positioned on the inside of the parking garage), the gate must be lifted out towards the outside to open. This forces the gate to open in the same direction for both the entrance and the exit. As a result, extra clearance must be provided before or after the gate to allow the gate to open and close. Thus, it is desirable to provide a lift gate system that can open the gate in either direction, while still concealing the operator from the outside.
U.S. Pat. No. 9,677,314, incorporated herein in its entirety, provided a hydraulic lift gate system and method of installation thereof designed to address the problems noted above. U.S. Pat. No. 9,677,314 discloses a lift gate system that includes a gate, a first pole, a second pole, a header and an internal operator that is hydraulic. The first pole is configured to attach to the ground on one side of the gate and included a first track attached approximate to a first top. The second pole is configured to attach to the ground on the opposite side of the gate from the first pole and includes a second track attached approximate to a second top. The header interconnects the first top with the second top. The internal operator is configured for lifting the gate, where the internal operator is inside the first pole, the second pole, and/or the header.
The instant disclosure recognizes the problem and/or need of the hydraulic lift gate system of U.S. Pat. No. 9,677,314 that there is no manual feature to the system disclosed therein that allows the hydraulic gate to be manually operated, i.e., that allows the hydraulic gate to be manually opened and closed. This manual override feature may be needed in the event of a failure, like when the power goes out, or the hydraulic internal operator needs service, as the gates or doors of such systems are very heavy. As such, there is clearly a need for a means or feature configured to open the hydraulic gate of U.S. Pat. No. 9,677,314, like when it is stuck in the closed or down position.
The instant disclosure may be designed to address at least certain aspects of the problems or needs discussed above by providing a swing gate mechanism configured to swing open an overhead hydraulic lift gate.
The present disclosure may solve the aforementioned limitations of the currently available lift gates and lift gate systems, by providing a feature to swing open an overhead lift gate system, like an overhead hydraulic lift gate. The swing gate mechanism to swing open the overhead lift gate system may generally include an overhead swing gate. The overhead swing gate may have a pivot side and a catch side. A first gate power arm may be configured to move along a first overhead guide track on a first side of the overhead lift gate system. A second gate power arm may be configured to move along a second overhead guide track on a second side of the overhead lift gate system. At least one hinge may be connected between the pivot side of the overhead swing gate and the first gate power arm. The at least one hinge may be configured to allow the overhead swing gate to swing open by rotating about the first gate power arm.
One feature of the disclosed swing gate mechanism to swing open the overhead hydraulic gate system may be that when the overhead swing gate is not swung open from the first gate power arm and the overhead swing gate is fixed between the first gate power arm and the second gate power arm, the overhead swing gate may have an overhead gate operation. The overhead gate operation may function via the first gate power arm moving in the first overhead guide track and the second gate power arm moving in the second overhead guide track.
Another feature of the disclosed swing gate mechanism to swing open the overhead hydraulic gate system may be that when the overhead swing gate is swung open from the first gate power arm, the overhead swing gate may have a swing gate operation.

In select embodiments, the swing operator may include a proximal end pivotally connected to the first gate power arm, and a distal end pivotally connected to a driving point positioned on the overhead swing gate. Wherein, the swing operator may be configured to adjust a distance between the distal end and the proximal end for controlling the rotation of the overhead swing gate about the first gate power arm for opening and closing the swing gate operation of the swing gate mechanism. In select embodiments, the swing operator may include a hydraulic operator configured to control the rotation of the overhead swing gate about the first gate power arm.
Another feature of the disclosed swing gate mechanism to swing open the overhead lift gate system may be that when the overhead swing gate is not swung open from the first gate power arm and the overhead swing gate is fixed between the first gate power arm and the second gate power arm, the overhead swing gate functions as an overhead gate via the first gate power arm moving in the first overhead guide track and the second gate power arm moving in the second overhead guide track, and when the overhead swing gate is swung open from the first gate power arm, the overhead swing gate functions as a swing gate.
