Abstract
Description
- The present invention relates to a track assembly for sectional overhead doors such as garage doors and the like. More specifically, this invention relates to such an assembly which is particularly suited for low headroom environments.
- Overhead sectional garage doors or the like are typically provided with rollers that ride in a track system usually carried by a horizontally oriented angle member extending inwardly from the door frame. When the door is in the closed position, the rollers reside in opposed vertically oriented tracks, and when moved to an open position, the rollers travel up the vertical tracks, through opposed transitional tracks, and into opposed generally horizontally oriented tracks.
- Traditionally, the transitional tracks are of a circular radius of curvature to make the ninety degree transition from the vertical tracks to the horizontal tracks. These transitional tracks may be a separate piece, having their ends attached to the vertical and horizontal tracks, or they may be incorporated into either the vertical tracks or the horizontal tracks thereby creating a two-piece system instead of a three piece system. In some instances, the track system may be formed as one piece incorporating the vertical tracks, the horizontal tracks and the transitional tracks.
- The radius of the typical prior art transitional tracks generally varies between eight inches and thirty inches. Radiuses toward the upper end of the range are desirable because such provides for a smoother operation of the door. However, such requires more headroom. In situations where there is minimal headroom, transitional tracks with a short radius must be utilized to the sacrifice of smooth operation.
- As a compromise, attempts have been made at providing a one piece track system which includes the vertical tracks, the horizontal tracks, and a transitional track portion having two radii of curvature. However, in order to accommodate for low headroom environments and yet still satisfactorily operate, the radii of curvature need to be quite different, that is, one of the radii needs to be substantially smaller than the other radii, and such cannot be readily accomplished in one piece.
- Thus, the need exists for a track system which is not plagued by these problems of the prior art.
- It is thus an object of the present invention to provide a track assembly for an overhead door which has the benefits of smooth operation while at the same time being usable in areas having low headroom.
- It is another object of the present invention to provide a track assembly, as above, which can easily be used with a header-mounted, pivoting motorized door operator.
- It is a further object of the present invention to provide a track assembly, as above, which does not require the support of a horizontally extending angle member.
- It is an additional object of the present invention to provide a track assembly, as above, which is easy to assemble and install.
- It is yet another object of the present invention to provide a track assembly, as above, which can be connected to a mounting bracket without the need for fasteners.
- These and other objects of the present invention, as well as the advantages thereof over existing prior art forms, which will become apparent from the description to follow, are accomplished by the improvements hereinafter described and claimed.
- In general, an overhead door track assembly made in accordance with the present invention includes a generally vertically positionable first track segment which has a straight portion and a curvilinear portion having a first radius of curvature. A generally horizontally positionable second track segment includes a straight portion and a curvilinear portion having a second radius of curvature. The second radius of curvature is larger than the first radius of curvature. Means are provided to connect the curvilinear portion of the first track segment to the curvilinear portion of the second track segment.
- In accordance with another aspect of the present invention, the track assembly which receives the rollers of an overhead door includes a first track segment having a generally straight portion and a curvilinear portion having a first radius of curvature. A second track segment has a generally straight portion and a curvilinear portion having a second radius of curvature. The curvilinear portions are attached to each other in such a way so as to form a continuous track for the rollers. The ratio of the second radius of curvature to the first radius of curvature is in the range of approximately twenty-to-one to approximately six-to-one.
- In another aspect of the invention, the track assembly includes a first track segment having a generally straight portion and a curvilinear portion having a first radius of curvature. A second track segment has a generally straight portion and curvilinear portion having a second radius of curvature. A bracket is attachable to the curvilinear portion of the first track segment and is attachable to the curvilinear portion of the second track segment so as to attach the first and second track segments to each other.
- A preferred exemplary track assembly for an overhead door made in accordance with the concepts of the present invention is shown by way of example in the accompanying drawings without attempting to show all the various forms and modifications in which the invention might be embodied, the invention being measured by the appended claims and not by the details of the specification.
- FIG. 1 is a fragmentary perspective view of a sectional overhead door having a track assembly made in accordance with the concepts of the present invention.
- FIG. 2 is an enlarged elevational view of the portion of the track assembly encircled in FIG. 1.
- FIG. 3 is an exploded perspective view of the components of the track assembly shown in FIG. 2.
- An overhead-type garage door is indicated generally by the
numeral 10 and includes a plurality ofpanels 11, each havingguide rollers 12 on the lateral edges thereof.Door 10 is formed within a frame which includes vertically oriented jambs J spaced by a header H, and is suspended by aconventional counterbalance system 13 which is schematically shown in FIG. 1.Rollers 12 ride in a track assembly which includes opposed generally vertically positionable track segments, generally indicated by thenumeral 14, and opposed generally horizontally positionable track segments generally indicated by thenumeral 15. - Each vertically
positionable track segment 14 includes astraight portion 16 which, when positioned for use withdoor 10, is generally vertically oriented, and includes acurvilinear portion 17 at one end thereof. Bothportions branches 18 interconnected by abase portion 19. As such,rollers 12 are adapted to be received betweenbranches 18 and directed thereby as they move alongtrack segment 14. - Similarly, each horizontally
positionable track segment 15 includes astraight portion 20 which, when positioned for use withdoor 10, is generally horizontally oriented, and includes acurvilinear portion 21 at one end thereof. Bothportions branches 22 interconnected by abase portion 23. As such,rollers 12 are adapted to be received betweenbranches 22 and directed thereby as they move alongtrack segment 15. - It has been found that the radius of curvature of
curvilinear portion 17 can be in the range of approximately four to eight inches. A radius of curvature of about four inches extending over approximately sixty-eight degrees is preferred. The radius of curvature ofcurvilinear portion 21 can be in the range of fifty to eighty inches depending on the height of thepanels 11 which make updoor 10. A radius of curvature of about seventy-one inches extending over approximately twenty-two degrees is preferred. Thus, the ratios of the radius ofportion 21 to the radius ofportion 17 could be in the range of approximately twenty-to-one to approximately six-to-one. The combination of these radii provide for smooth operation while at the same time rendering thedoor 10 useable in areas of low headroom. -
Curvilinear portion 17 is attached tocurvilinear portion 21 by means of a flag angle or bracket generally indicated by thenumeral 30. As shown in FIGS. 2 and 3,bracket 30 is generally L-shaped in configuration having a generally vertically orientedstructural mounting face 31 and a generally horizontally oriented trackengaging face 32. Anoffset rib 33 runs down mountingface 31 and extends into trackengaging face 32, and asecond offset rib 34 runs along the junction offaces ribs bracket 30. -
Mounting face 31 includes anaperture 35 to facilitate attachment to a portion ofcounterbalance system 13, and the top offace 31 is provided with anotch 36 to permit the passage ofcounterbalance system 13 therethrough. As shown in FIG. 3,face 31 is also provided with amounting flange 37 having a plurality (one shown) ofapertures 38 therein to facilitate attachment ofbracket 30 to the header H or a jamb J of the frame arounddoor 10.Flange 37 is integrally formed with aflange 39 on trackengaging face 32 to further strengthenbracket 30. - Track
engaging face 32 ofbracket 30 is provided with a pair oftabs 40 spaced fromface 32 and oriented 180° of each other.Face 32 is also provided with alock lug 41 which is also spaced fromface 32. Thebase portion 19 oftrack portion 17 is provided with aslot aperture 42 which is generally circular in shape with its circumference being interrupted by a pair of diametrically opposedsemicircles 43. Thebase portion 23 oftrack portion 21 is provided with a tapered, generally tear drop-shaped,slot 44 having anend 45 with a narrow opening and anend 46 with an opening wider than the opening atend 45. Thelarger end 46 is positioned to be adjacent to the end oftrack portion 21. - In order to attach
curvilinear portion 17 oftrack segment 14 tocurvilinear portion 21 oftrack segment 15, and thereby install the track assembly for use withdoor 10,tabs 40 ofbracket 30 are aligned withopposed semicircles 43 ofslot aperture 42 and then pushed therethrough. Then,bracket 30 andtrack segment 14 can be rotated ninety degrees relative to each other so thatbracket 30 is engagingtrack segment 14 as shown in FIG. 2. Thereafter, in order to attachcurvilinear portion 21 tobracket 30 and tocurvilinear portion 17 to tracksegment 14, the end ofcurvilinear portion 21 can be slid into, or otherwise telescoped into, the end ofcurvilinear portion 17. For this purpose, the U-shaped profile ofportion 17 is enlarged near the end ofportion 17, as at 47, to receive the end ofportion 21. As such, there is a smooth roller transition betweenportions rollers 12 as they pass betweentrack segment 14 andtrack segment 15. At the same time that trackportion 21 is slid intotrack portion 17, lug 41 ofbracket 30 is received through thelarge end 46 ofslot 44. Whenportion 21 is fully seated inportion 17,lug 41 will be positioned in thesmaller end 45 ofslot 44 such thatbracket 30 is then holdingtrack portion 21. - At this point,
bracket 30 may be attached to the door frame while carrying and attaching one end oftrack segments track segments track portion 21 cannot be slid out oftrack portion 17 and otherwise released frombracket 30. - It should be appreciated that a track assembly constructed and installed as described herein does not require the conventional horizontally extending support angle at the area of the transition of the track from vertical to horizontal because the long
curvilinear portion 21 effectively acts to provide such support. In addition, this track assembly enables one to use a header mounted pivotal door operator without requiring additional components to account for the lack of headroom as was required in the prior art. That is, whendoor 10 is moving through the track assembly of the present invention,door 10 begins to move back almost immediately ontrack segment 15 which allows one to use a pivotal door operator which is desirable to lock the door in the down position. - As such, the track assembly described herein substantially improves the art and otherwise accomplishes the objections of the present invention.
