Referring to
The gate system 10 is shown in the closed position in
Referring to
The dimensions of the first gate portion 16 and the second gate portion 18 and the travel distances of the first gate portion 16 and the second gate portion 18 may be selected for a particular gate system 10 to allow people and/or vehicles to pass through the pathway 14 of the gate system 10 when the gate system is open. For example, gate systems according to the present disclosure that are designed for selectively allowing automobiles to pass through the pathway may have longer gate portions 16, 18 and greater travel distances gate portions than narrower gate systems that are only sufficiently wide to allow people to pass through the pathway.
As mentioned above, the base 12 supports the components of the gate system 10 and may be formed of various materials. In some embodiments, the base 12 includes concrete, metal, and/or another material. The base 12 may be secured to an adjacent barrier, such as a wall. The base 12 is sufficiently firm to support the first rail 22, the second rail 24, and additional rails if needed.
The first rail 22 is configured to support the first gate portion 16 as the first gate portion travels 16 along the first rail 22, as described in more detail below. The second rail 24 is configured to support the second gate portion 18 as the second gate portion 18 travels along the second rail 24, as described in more detail below. The first rail 22 and the second rail 24 are substantially parallel to each other.
In one embodiment, the rails 22, 24 are constructed to reduce noise of the gate system 10. Referring to
The frame 20 supports the gate portions 16, 18 and maintains the gate portions in an upright position while the gate portions 16, 18 are seated on the rails 22, 24. The frame 20 includes a tower having four posts, each indicated at 46, extending upwardly from the base 12. Each post 46 includes a lower end secured to the base 12 and an upper end secured to a plate 48 (as shown in
The motor 26 is secured to the base 12 and is adjacent to the tower of the frame 20. In
As shown in
The motor 26 may have a power output that is selected based on the desired performance of the gate system 10. For example, the motor 26 may be selected based on the weight of the gate portions 16, 18 and based on the desired speed of the gate portions 16, 18 when the motor 26 is being operated to open or close the gate system 10.
The first gate portion 16 includes an upper end and a lower end. The first gate portion 16 is supported at its lower end by the first rail 22 and at its upper end by the frame 20. Movement of the first gate portion along the first rail 22 may be caused by the motor 26, which is coupled to the first gate portion 16, as described below.
As shown in
As shown in
A plurality of wheels, indicated at 62, are secured to the lower end of the first gate portion 16. The plurality of wheels 62 are configured to roll along the first rail 22. In some embodiments, each wheel 62 may be made of one or more materials including metal and/or other materials. In some embodiments, each wheel 62 is made of steel. Steel is less noisy than other materials would be when the wheel 62 rolls over the aluminum layer 44 of the rail 16.
The lower end of the first gate portion 16 includes a first rack 64, which is configured to be driven by the first pinion 52 of the motor 26. The first rack 64 includes teeth that are configured to mesh with teeth of the first pinion 52. In this way, clockwise rotation of the motor drive shaft 38 causes the first gate portion 16 to translate along the first rail 22 in a first direction, and counterclockwise rotation of the motor drive shaft 38 causes the first gate portion to translate along the first rail 22 in a second direction that is opposite to the first direction.
To drive motion of the second gate portion 18, the second gate portion 18 includes a second pinion 66, which is rotatably secured to a wheel selected from the first plurality of wheels 62.
As shown in
The second gate portion 18 is supported at its lower end by the second rail 24 and at its upper end by the first gate portion 16. Movement of the second gate portion 18 along the second rail 24 may be caused by movement of the first gate portion 16 along the first rail 22 when the second gate portion 18 and the first gate portion 16 are coupled to one another, as discussed in more detail below. The user may selectively uncouple the second gate portion 18 from the first gate portion 16 to move the second gate portion 18 manually and independently from the first gate portion, as described in more detail below.
As shown in
As shown in
The channel 78 is inverted, so the rollers 68 engage the channel 78 from below. The inverted channel 78 helps conceal the rollers 68 from view, thereby improving the aesthetic appearance of the gate system. The inverted channel 78 also shields the rollers 68 from the elements, such as rain or debris, which could damage or inhibit operation of the rollers 68.
A plurality of wheels, indicated at 80, are secured to the lower end of the second gate portion 18. The plurality of wheels 80 are configured to roll along the second rail 24. In some embodiments, each wheel 80 may be made of one or more materials including metal and/or other materials. In some embodiments, each wheel 80 is made of steel. Steel is less noisy than other materials would be when the wheel rolls over the aluminum of the rail.
The lower end of the second gate portion 18 includes a second rack 82, which is configured to be driven by the second pinion 66 of the first gate portion 16 via a clutch gear 84 (
The clutch gear 84 includes a handle to allow a user to manually disengage the clutch gear 84 from the second pinion 66 and the second rack 82. A user pulls the handle of the clutch gear 84 to slide the clutch gear 84 along its axis to disengage the clutch gear 84 from the second pinion 66. To couple the clutch gear 84 and the second pinion 66, the user pushes the handle in the opposite direction.
In some embodiments, the clutch gear 84 and the second pinion 66 have a gear ratio that causes the second gate portion 18 to travel faster than the first gate portion 16. In some embodiments, the clutch gear 84 and the second pinion 66 have a gear ratio that causes the second gate portion 18 to travel at twice the speed of the first gate portion 16.
The gate system includes position sensors, each indicated at 92, located at the first travel limit 28 and the second travel limit 30. The sensors 92 are configured to detect positions of the gate portions 16, 18. The gate system includes a controller 94 in communication with the sensors 92 and the motor 26. In various embodiments of the gate system 10, the controller 94 may be in wired and/or wireless communication with the sensors 92 and the motor 26. The controller 94 is configured to send a signal to the motor 26 based on a sensed position of the first gate portion 16 or the second gate portion 18. For example, the controller 94 is configured to send a signal to the motor to shut off when the second gate portion 18 reaches the second travel limit 30 or when the second gate portion reaches the first travel limit 28.
Some embodiments of a gate system of the present disclosure may include more than two gate portions. For example,
To drive motion of the third gate portion 102, the second gate portion 18 of the gate system 100 further includes a third pinion (not shown), which is rotatably secured to a wheel selected from the second plurality of wheels 80.
As shown in
Similar to the first gate portion 16 and the second gate portion 18, the third gate portion 102 includes a first horizontally extending beam at the upper end of the third gate portion 102 and a second horizontally extending beam at the lower end of the third gate portion 102. A plurality of bars extend vertically between the first horizontally extending beam and the second horizontally extending beam. Gaps between the vertically extending bars allow a user to see from one side of the third gate portion to the other. Solid panels may be provided in place of the bars.
A channel 114 is secured along a length of the upper end of the third gate portion 102 and is configured to receive the third plurality of rollers 110 of the second gate portion 18. As the third gate portion 102 translates along the third rail 104, the third plurality of rollers 110 roll within the channel 114 and maintain the vertical orientation of the third gate portion 102 with respect to the second gate portion 18.
The channel 114 is inverted, so the rollers 110 engage the channel 114 from below. The inverted channel 114 helps conceal the rollers 110 from view, thereby improving the aesthetic appearance of the gate system. The inverted channel 114 also shields the rollers 110 from the elements, such as rain or debris, which could damage the rollers 110.
A plurality of wheels, indicated at 116, are secured to the lower end of the third gate portion 102. The plurality of wheels 116 are configured to roll along the third rail 104. In some embodiments, each wheel may be made of one or more materials including metal and/or other materials. In some embodiments, each wheel is made of steel. Steel is less noisy than other materials would be when the wheel rolls over the aluminum of the rail.
The lower end of the third gate portion 102 includes a third rack 118, which is configured to be driven by the third pinion of the second gate portion. The third rack includes teeth that are configured to mesh with teeth of the third pinion.
Various controllers may execute various operations discussed above. For example, as discussed above, the controller, such as controller 94, may control the components of the gate system 10, including the motor 26, amongst other operations. Using data stored in associated memory and/or storage, the controller 94 may execute one or more instructions stored on one or more non-transitory computer-readable media, which the controller 94 may include and/or be coupled to, that may result in manipulated data. In some examples, the controller 94 may include one or more processors or other types of controllers. In one example, the controller 94 is or includes at least one processor. In another example, the controller 94 performs at least a portion of the operations discussed above using an application-specific integrated circuit tailored to perform particular operations in addition to, or in lieu of, a general-purpose processor. As illustrated by these examples, examples in accordance with the present disclosure may perform the operations described herein using many specific combinations of hardware and software and the disclosure is not limited to any particular combination of hardware and software components. Examples of the disclosure may include a computer-program product configured to execute methods, processes, and/or operations discussed above. The computer-program product may be, or include, one or more controllers and/or processors configured to execute instructions to perform methods, processes, and/or operations discussed above.
As described above, gate systems of the present disclosure have various advantages over prior art gate systems. For example, gate systems of the present disclosure are quiet because of the materials used for the wheels and the rails along which the wheels travel. Gate systems of the present disclosure are configured for optional manual operation, which may be desirable during power outages. Gate systems of the present disclosure include movable gate portions that are supported by a frame so the gate portions are resistant to tipping. Gate systems of the present disclosure are suitable for providing a secure gate on pathways of various widths.
Having thus described several aspects of at least one embodiment of this disclosure, it is to be appreciated various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure, and are intended to be within the spirit and scope of the disclosure. Accordingly, the foregoing description and drawings are by way of example only.
