     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 7 thereof, a new and improved garage door locking apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the garage door locking apparatus 10 of the instant invention essentially comprises a garage door 11, having a door first side 15 spaced from a second side 16, a door first end 17 spaced from a door second end 18. A motorized opener 12 is provided mounted in a spaced relationship relative to the door 11, with the opener 12 having a track 13 extending from the garage door opener to an opposing wall structure in a conventional manner. The track includes a track carriage 14 that is reciprocatably mounted about the track 13 and driven by either a drive chain or a gear structure, in a manner known in the prior art. The track carriage 14 includes a door connector assembly 19 (see FIGS. 5-7), with the door connector assembly operative through respective first and second pulleys 20 and 21 mounted to the garage door on opposed sides of the connector assembly adjacent the first end 17. Third and fourth pulleys 22 and 23 respectively are mounted to the door adjacent the first end 17 and the respective first and second sides 15 and 16. Respective first and second cables 53 and 54 mounted to the door connector assembly 19 are operative through the pulley structure, in a manner as indicated in FIGS. 1 and 2, and in operative communication to respective first and second latch assemblies 44 and 45 mounted to the respective door 11 adjacent the first and second sides 15 and 16 and the second end 18. 
     The door connector assembly 19 includes door mounting boss 28 fixedly secured to the door 11, with the door mounting boss 28 having a door mounting boss axle 29, while a first door tube 30 includes a mounting flange 31 coaxially aligned relative to the door tube 30, having a mounting flange aperture 32 receiving the axle 29 pivotally mounting the first door tube 30 relative to the door mounting boss 28. A second door tube 30a is arranged in a spaced coaxially aligned relationship relative to the first door tube 30 and secured integrally thereto by a connecting web 41. The second door tube 30a includes an entrance end 33, with respective first alignment ring 34 mounted to the entrance end 33, and a second alignment ring 35 mounted to an exit end 33a of the second door tube 30a. A slide rod 36 accordingly is slidably directed in a coaxially aligned relationship through the first and second alignment rings 34 and 35, with the slide rod 36 slidably directed into the first door tube 30 in a coaxially aligned relationship. A first abutment 37 is mounted to the slide rod 36, with the first abutment 37 arranged in abutment with the second door tube entrance end 33 in a first position, and the first abutment 37 spaced from the entrance end 33 in a second position, as indicated in FIG. 6 for example. A second abutment 38 is mounted to the slide rod 36 intermediate the first and second door tubes 30 and 30 a, with the second abutment 38 arranged in abutment with the first door tube in the first position and in abutment with the second door tube exit end 33 in the second position, as indicated in FIGS. 5 and 6 respectively. A door tube floor ring 39 is fixedly mounted within the first door tube adjacent the mounting flange 31 to slidably receive the slide rod 36 therethrough, and additionally provide abutment for a door spring 40 that extends from the door tube floor ring 39 to the slide rod second abutment 30a. In this manner, when the garage door 11 is in a closed first position, as illustrated in FIG. 1, and the door connector assembly 19 is in the first position with the first abutment in engagement with the second door tube entrance end 33 the door spring 40 biased against the door tube floor ring 39 biases the first and second door tubes to bias the garage door in the first position exerting spring pressure upon the garage door 11. As illustrated in FIG. 5 for example, a carriage axle 43 is directed through a slide rod angulated end portion 42 extending laterally from the slide rod pivotally mounting the slide rod angulated end portion 42 to the track carriage 14. 
     The cross pin 27 mounted to the slide rod 36 adjacent the slide rod angulated end portion 42 extends orthogonally through the slide rod 36, in a manner as illustrated in the FIGS. 1 and 2. 
     As noted above, the first cable 53 extends from the cross pin 27 through the first pulley 20, the third pulley 22, and to the first latch assembly 44. The second cable 54 extends from the cross pin 27 slidably along the respective second and fourth pulleys 21 and 23 to the second latch assembly 45. The first and second latch assemblies 44 and 45 each include an individual latch rod 48 (see FIGS. 3 and 4), with the first and second latch rod of the first and second latch assemblies 44 and 45 received within respective garage floor first and second latch cavities 25 and 26 to direct the respective latch rods into the respective latch cavities of the latch floor 24. 
     With reference to the FIGS. 3 and 4, and as the first and second latch assemblies 44 and 45 are of identical construction, for purposes of illustration, only one such latch assembly is to be described and illustrated but it is to be understood that the structure is representative of each latch assembly 44 and 45 in use. A latch cylinder 46 is provided relative to each latch assembly, having a latch cylinder slot 47 directed through the latch cylinder wall parallel to the axis 46a of the associated latch cylinder 46, with the latch rod 48 slidably received through the latch cylinder 46. A first latch anchor 49 is mounted to the latch cylinder 46 at a forward end of the latch cylinder, with the latch rod 48 directed into the latch cylinder through a second end of the latch cylinder, with a second spring anchor 50 mounted to the latch rod 48. A latch spring 51 indicated between the first and second spring anchors 49 and 50 bias the latch rod 48 to project through the first end of the latch cylinder 46 to be received in an associated latch cavity. A latch rod guide lug 52 mounted to the latch rod is slidably received within the slot 47 to guide the latch rod within the latch cylinder 46. In this manner, when the garage door is directed to the second position, as indicated in FIG. 2, the associated cable structures 53 and 54 relative to the respective first and second latch assemblies 44 and 45 withdraws the respective latch rod 48 to extend the respective latch rod relative to the respective latch cylinder of the latch assemblies. It should be further noted that, as illustrated, the latch rods are directed into the floor of the garage, the latch assemblies may be rotated ninety degrees, with associated respective guide structure to direct the latch rods into the door frame portions of the associated garage door. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, 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 the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention 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 invention.
