DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 6 thereof, a new locking device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 6, the door locking system 10 generally comprises a door 12 movably mounted on a rail 14. The door 12 includes rollers 16 rollably coupling the door 12 to the rail 14. The door 12 may be a garage door of any conventional design.
An opener 18 is coupled to the door 12. The opener 18 positions the door 12 in an open position and a closed position. The opener 18 may be an automatic garage door opener of any conventional design. Additionally, the opener 18 detects when the door 12 has been moved into the closed position and the open position.
A lock 20 is coupled to the rail 14. The lock 20 is in communication with the opener 18. The lock 20 is automatically positioned in a locked position after the opener 18 positions the door 12 in a closed position. Thus, the door 12 is retained in the closed position. The lock 20 prevents the door 12 from being forced open.
The lock 20 comprises a bracket 22 that has a pair of bends 24 thereon to define a first section 26 and a second section 28. The first 26 and second sections 28 each form an angle with respect to a central section 30. The first section 26 and the second section 28 extend in opposite directions from the central section 30.
The bracket 22 is coupled to the rail 14 such that the first section 26 abuts the rail 14. The central section 30 extends laterally away from the rail 14. The second section 28 has a first end 32. The bracket 22 has a groove 34 extending inwardly from the first end 32 and continuing onto the central section 30.
A housing 36 has a bottom wall 38 and a perimeter wall 40 extending upwardly therefrom. The perimeter wall 40 has a back side 42 and a front side 44. The housing 36 is coupled to the central section 30 such that the front side 44 is positioned between the rail 14 and the back side 42. The front side 44 has a first aperture 46 extending therethrough. The back side 42 has a second aperture 48 extending therethrough.
A drive 50 is positioned within the housing 36. The drive 50 is electrically coupled to the opener 18. The drive 50 may be an electrical solenoid or the like. A conductor 52 is electrically coupled between the drive 50 and the opener 18.
A rod 54 has a first end 56 and a second end 58. The rod 54 extends through the drive 50 such that the first end 56 is directed through the first aperture 46 and the second end 58 is directed through the second aperture 48. The rod 54 is mechanically coupled to the drive 50.
The rod 54 has a first section 60 and a second section 62. The first section 60 extends from the first end 56 to a middle 64 of the rod 54. The second section 62 extends from the middle 64 of the rod 54 to the second end 58 of the rod 54. The first section 60 may have a diameter between 10 mm and 15 mm. The second section 62 may have a diameter between 7 mm and 10 mm. The rod 54 may have a length between 12 cm and 18 cm.
The drive 50 urges the rod 54 to extend through the rail 14 when the opener 18 detects the closed position of the door 12. The rollers 16 abut the rod 54 such that the door 12 is prevented from is moved from the closed position. The drive 50 urges the rod 54 away from the rail 14 when the opener 18 receives a signal to open the door 12. Thus, the door 12 is allowed to be positioned in the open position.
A spring biasing member 66 is positioned around the rod 54 between the first end 56 and the front side 44 of the housing 36. A clip 68 is non-movably coupled to the rod 54 between the spring biasing member 66 and the first end 56. The spring biasing member 66 biases the first end 56 of the rod 54 away from the front side 44.
A handle 70 is coupled to the rod 54. The handle 70 is positioned proximate the second end 58 and is oriented transverse to the rod 54. The handle 70 is positioned within the groove 34 in the central section 30. Moreover, the handle 70 is manually urgeable away from the back side 42 of the housing 36 such that the rod 54 is positioned in the unlocked position.
In use, the opener 18 positions the door 12 in the closed position. The rod 54 engages the rail after the door 12 has fully closed. The handle 70 is used to unlock the door 12 if the opener 18 or the drive 50 experiences a mechanical failure. The door 12 may be manually moved into the open position after the handle 70 is used to unlock the door 12.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
