For a more complete understanding of the present invention, including its features and advantages, reference is now made to the detailed description of the invention taken in conjunction with the accompanying drawing in which:
While the making and using of various embodiments of the present invention are discussed in detail below, it should be appreciated that the present invention provides many applicable inventive concepts that may be embodied in a wide variety of specific contexts. The specific embodiments discussed herein are merely illustrative of specific ways to make and use the invention and do not delimit the scope of the invention.
The present invention includes a system to lock an automated swing gate operator arm to a gate.
In the past, Fire Marshals ultimately require a manual release for any automated gate across a fire lane to gain access to the property in case of an emergency. Generally, a Knox™ Fire Department padlock secures a manual release. Currently, two Knox™ padlocks are in use and have a ⅜″ or 7/16″ diameter shank. However, gate pins to attach an automated swing gate arm to a gate are typically ½″ in diameter. One issue that occurs with the present solution is drilling a ⅜″ or larger hole through the pin to accommodate current padlock shanks leaves too little metal to be structurally sound.
Currently, a solution does not exist that addresses this issue. The present invention, the “911 Pin Lock”, resolves the problem of complying with Fire Marshals requirements for gate operators across fire lanes, as well as providing a way to secure a gate operator arm for a residential or commercial consumer installation.
The 911 Pin Lock provides a grooved pin (“modified pin”) and a milled metal block (“modified block”). The modified pin is inserted through a gate bracket and a gate operator arm, and the modified block slides over the end of the modified pin. A hole in the side of the modified block allows a shank of a padlock to be inserted, whereby the shank of the padlock engages a groove in the modified pin thereby securing the pin.
Now referring to
One embodiment of the system consists of a 0.5″ hole 220 drilled offset into the modified block 230 to a depth of 1.25″ 206 and accepts the modified pin 100. A 0.453″ diameter padlock hole 220 is then drilled through the modified block 230 at a 90° angle opposed to the ½″ pin hole 204, and intersecting the pin hole 204. In addition, the modified pin 100 has a milled curved groove 116 in the shank 101 of the pin 100. Thus, when the modified pin 100 is inserted into the modified block 230, through the pin hole 204, the groove 116 creates a pathway to accept a shank 218 of a padlock.
Specifically in this embodiment, the modified pin 100 includes a head with a 0.165 width 106, a shank 101 of 3.5″ length 114, 0.50″ circumference 102 with the groove 116 milled at a radius of 0.1875″ and 0.602″ width 108 and a 0.235″ circumference 104. The distance 112 from the center of the groove 116 to the end of the shank 101 opposite of the head is 1.0″ in length. In addition, the end of the shank in this embodiment has a 45 degree 110.
In addition, referring to cross section 2A in
In this embodiment, a fire marshal or other user could cut the shank of the modified pin to remove the gate if necessary.
Another embodiment of the present invention includes two modified blocks and a longer shank of the modified pin that interconnects the modified blocks. In this embodiment, a first block attaches to a padlock and one end of the longer modified pin, in a similar method as the embodiment illustrated above, but is connected before a second modified block with a second padlock attaches the gate and fence railing. This embodiment would expose the shank between the first and second block to provide a user a wider area to cut the shank if needed.
Although this invention has been described with reference to an illustrative embodiment, this description is not intended to limit the scope of the invention. Various modifications, such as dimensions of the padlock, the modified pin and the modified block, and combinations, as of the illustrative embodiments as well as other embodiments of the invention will be apparent to persons skilled in the art upon reference to the description. It is therefore intended that the appended claims accomplish any such modifications or embodiments.
