Description

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a garage door/track/coupler system and, more particularly, pertains to new and novel coupling assemblies and new and novel track assemblies used to slidably couple a secondary one-piece garage door that is used as a screened closure for the garage to the secondary tracks on which the secondary garage door moves. The objectives of the present invention are achieved in a safe, convenient and economical manner.

SUMMARY OF THE INVENTION

In view of the foregoing disadvantages inherent in the known types of garage door systems now present in the prior art, the present invention provides an improved garage door/track/coupler system. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved garage door/track/coupler system and method which has all the advantages of the prior art and none of the disadvantages.

The garage door/track/coupler system of the present invention is for slidably coupling a one-piece garage door to inverted L-shaped guide tracks through wheeled coupling assemblies. The coupling is done in a convenient and economical manner.

First provided in the preferred embodiment is a one-piece garage door. The garage door has a rectangular configuration with a horizontal upper rail and a parallel lower rail separated by a height. The garage door has a vertical first side rail and a parallel second side rail separated by a width. Each of the rails is rigid. The garage door has a screen secured to, and extending between, the upper and lower and side rails. The garage door has a front face and a rear face. A small screen door is mounted in the garage door. The screen door constitutes between 12.5 and 25 percent of the area of the garage door. The screen door is movable with respect to the garage door between an open orientation and a closed orientation.

Next provided is a track assembly. The track assembly has a horizontal first upper track and a parallel second upper track. The first and second upper tracks are separated by a width greater than the width of the garage door. The track assembly has a vertical first lower track and a parallel second lower track. The first and second lower tracks are separated by a width greater than the width of the garage door. Each of the upper and lower tracks has a C-shaped cross-sectional configuration with a maximum height of 2 inches plus or minus 10 percent. Each track has an interiorly facing opening of between 0.25 and 0.75 inches. Newly designed and manufactured arcuate intermediate tracks couple one upper track with one lower track into an inverted L-shaped configuration. A first intermediate track couples the first upper track to the first lower track forming the first track assembly. A second intermediate track couples the second upper track to the second lower track forming the second track assembly. Each intermediate track has a radius of curvature between 1 and 2 inches. The intermediate tracks have an interiorly facing opening and guides to maintain a continuous interior channel from the horizontal upper track to the vertical lower tracks. The tight radius of curvature is necessary to allow the secondary garage door to operate within the available clearances of the garage chamber. The first and second track assemblies allow the one-piece garage door to slide from horizontal open position to vertical closed position within this tight curvature.

Next provided are newly designed and manufactured upper hinged brackets. The first upper hinged bracket is secured to the rear face of the garage door adjacent to an intersection of the upper rail and the first side rail. The second upper hinged bracket is secured to the rear face of the garage door adjacent to an intersection of the upper rail and the second side rail. A perpendicular arm extends interiorly from each upper hinged bracket. A hinge pin is secured to each arm parallel with the upper and lower rails of the garage door and connects the perpendicular arm to a hinged wheel assembly. The hinged wheel assembly is made up of a flat-bottomed U-shaped arm extending from the hinge pin to an axle. The axle extends through the opening of the upper track. A plurality of rollers is provided next. One roller is secured to each axle and rotatably received within the upper tracks. The upper hinged brackets are necessary to allow the secondary garage door to operate within the available clearances of the garage chamber, to keep its rollers in the upper tracks at all times and to allow the garage door to be in the desired position when open and closed.

Next provided are newly designed and manufactured lower brackets. The first lower bracket is secured to the rear face of the garage door adjacent to an intersection of the lower rail and the first side rail. The second lower bracket is secured to the rear face of the garage door adjacent to an intersection of the lower rail and the second side rail. A perpendicular arm extends interiorly from each lower bracket. An axle is secured to each arm parallel with the upper and lower rails of the screen door. The axle extends through the opening of the lower track. One roller is secured to each axle and rotatably received within the lower tracks. The lower brackets are necessary to allow the garage door to be in the desired position when open and closed and to allow its rollers to move from the lower track to the upper track as the garage door moves from the closed to the open position and vice versa.

Lastly, a lifting rod is secured to the first lower bracket. A cable has a first end coupled to the lifting rod and a second end coupled to a spring. The cable has an intermediate extent trained around a pulley. The pulley has an axis of rotation passing through the first intermediate track. A lifting rod is secured to the second lower bracket. A cable has a first end coupled to the lifting rod and a second end coupled to a spring. The cable has an intermediate extent trained around a pulley that has an axis of rotation passing through the second intermediate track. The lifting mechanism thereby formed reduces the amount of effort required to lift the garage door from the closed lower orientation to the open raised orientation. The lifting mechanism also allows the garage door to be gently lowered from the open raised orientation to the closed lower orientation.

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims attached.

Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

First provided is a garage 14. The garage has a chamber with a front opening. The garage has a horizontal floor 16. The garage has a parallel ceiling 18. The ceiling is spaced for a garage door with a height of between about 6 feet and about 16 feet. The garage has vertical side walls 20. The side walls are spaced for a garage door with a width of between about 8 feet and about 20 feet.

Primary tracks 24 are provided. Each track is in an inverted L-shaped configuration. Each track is mounted to a side wall. Each primary track has a vertical section within the chamber adjacent to the front opening. Each track has a horizontal section extending into the chamber. Each primary track has a curved intermediate section 26. The intermediate section has a radius of curvature of about 15 inches. Each primary track is adapted to receive and support a primary garage door. In this manner movement is allowed between a closed orientation between the vertical sections and an open orientation between the horizontal sections.

Secondary tracks 30 are provided. Each secondary track is in an inverted L-shaped configuration. Each secondary track is mounted with respect to a side wall. Each secondary track has a vertical section adjacent to the front opening. Each secondary track has a horizontal section extending into the chamber and depending from the primary track. Each secondary track has an arcuate intermediate section 32. The intermediate section has a radius of curvature of between 1 and 2 inches. The secondary track with its intermediate section is radially interior of and spaced a common distance from the primary track.

Provided next is a single panel secondary garage door 36. The secondary garage door has upper and lower rails 38,40. The secondary garage door has side rails 42.

Next provided is a cylindrically shaped spring cartridge 350. The spring cartridge is located in the housing post with upper and lower ends mounted for rotational movement about a vertical axis. The spring cartridge has an exterior surface receiving and supporting the constrained edge of the screen door. In this manner, rotation of the cartridge in a first direction will allow the screen door to cover the opening 316 while rotation of the cartridge in an opposite second direction will allow the door to uncover the opening.

Next, an upper end cap 354 between the upper end of the cartridge and the upper rail is provided. Also a lower end cap 356 is provided between the lower end of the cartridge and the lower rail. A plurality of self-tapping screws 358 couple the end caps to the rails and to the cartridge. The upper end of the cartridge is formed with an upstanding tab 360. The upper end cap is formed with a slot 362 receiving the upstanding tab for controlling the rotation of the cartridge and reciprocation of the door. Each end cap has a lateral projection 364 receiving and supporting the upper and lower tracks. Vertically extending short posts 366 are formed in each end cap and received in the upper and lower ends of the hollow housing post to provide rigidity.

Lastly, horizontal spline grooves 370, 372 are formed in the upper and lower rails. Vertical spline grooves 374, 376, 378 are formed in alignment in the upper end cap and the housing post and the lower end cap. The spline grooves are adapted to receive and support screens and splines while allowing for efficient screen replacement.

FIGS. 14, 15 and 16 illustrate the preferred embodiment of the invention with the spline grooves for the end caps and the housing post being in an angularly disposed, rectangular configuration. Alternate configurations of spine grooves for different types of splines are included in the present invention. One alternate configuration includes essentially square spline grooves 376A as shown in FIG. 14A. Another alternate configuration includes essentially circular spline grooves 376B as shown in FIG. 14B.

The preferred embodiment of the garage door/track/coupler system 400 for slidably coupling a one-piece garage door to inverted L-shaped guide tracks through wheeled coupling assemblies, is shown in FIGS. 17-29. The coupling is done in a convenient and economical manner.

Each track has an interiorly facing opening 474 of between 0.25 and 0.75 inches. Newly designed and manufactured arcuate intermediate tracks 428 couple one upper track 420 with one lower track 424 into an inverted L-shaped configuration. A first intermediate track 428 couples the first upper track 420 to the first lower track 424 forming the first L-shaped track assembly. A second intermediate track 430 couples the second upper track 422 to the second lower track 426 forming the second L-shaped track assembly. Each intermediate track has a radius of curvature between 1 and 2 inches. The intermediate tracks have an interiorly facing opening 432 and guides 476, 478 to maintain a continuous interior channel from the horizontal upper tracks to the vertical lower tracks. The tight radius of curvature is necessary to allow the secondary garage door to operate within the available clearances of the garage chamber. The first and second track assemblies allow the one-piece garage door to slide from horizontal open position to vertical closed position within this tight curvature.

Next provided are newly designed and manufactured upper hinged brackets 436.
