This invention relates to sectional doors. More specifically, this invention relates to sectional overhead doors that replicate wood sectional carriage house garage doors.
A typical overhead garage door is constructed from a series of door panels, which are hinged together and supported from a track system with rollers attached to opposite ends of the door panels. The rollers allow the door to be moved from a vertically oriented closed position to a substantially horizontal open position. Electrically powered garage door openers are often used with the overhead garage door so that a user may conveniently open and close the door with ease.
In most residential applications, an overhead garage door is generally either eight or sixteen feet wide. Typically, such a door includes four horizontally oriented door panels, each of which is about eight or sixteen feet wide and twenty-one inches high. For example, a single car residential garage may have an eight foot wide by seven foot high door. Likewise, a two car residential garage may have a single sixteen foot wide door by seven foot high door or two eight foot wide by seven foot high doors.
Some of the earliest doors made for garages were one piece barn doors that operated horizontally as large swinging or sliding doors. The nostalgic design of these doors is replicated in wood sectional carriage house garage doors. Wood sectional carriage house garage doors are particularly desirable for use with older homes to maintain the historic design of the home while gaining the convenience and other benefits of the modern overhead garage door. Carriage house garage doors are also desirable with newer homes for enhancing the overall appearance of the garage and consequently the house. Carriage house doors often include a series of vertical wooden slats in a perimeter frame. Commonly, one or more diagonal or transverse wooden slats overlay the vertical slats for added strength and rigidity to the door.
A sectional carriage house door functions like a typical overhead garage door in that it moves on a track and roller system to open and close the door. However, the appearance of the sectional carriage house door simulates the historic swing type doors used in early automobile shelters. The historic appearance of the sectional carriage house door may be created by various types of wood siding, wood slats, wood trim boards, and/or wood raised panels.
Unfortunately, a wood carriage house garage door is very costly relative to a conventional steel overhead garage door. This cost is due in part to labor costs for the largely manual process of constructing the wood carriage house door. Furthermore, the material cost for the wood siding, wood slats, wood trim boards, and/or wood raised panels is undesirably high. Thus, a homeowner may pay five to six times more for a wood carriage house door than for a conventional steel overhead door.
In addition to the costly initial investment, wood carriage house doors are costly to maintain. In particular, the wood is adversely affected by the elements. That is sun, rain, snow, varying temperatures, and so forth may degrade the finish of the wood and eventually cause the wood to warp, split, or rot if not properly treated and maintained. Consequently, the wood carriage house garage door should be resealed or re-painted every couple of years to maintain the aesthetic appearance and integrity of the wood carriage house garage door. This labor intensive and costly maintenance is highly undesirable to the typical homeowner.
Another problem with a wood carriage house garage door results from the weight of the wood siding, wood trim board, and/or wood raised panels, which typically adds one hundred to two hundred pounds to the overall weight of the sectional carriage house door. In particular, the wood or steel open frame door sections often lack the structural integrity or the strength to adequately support the added weight of the wood siding.
Some recent garage door designs attempt to gain the benefits of modern steel overhead sectional door technology and simulate the aesthetic appeal of traditional carriage house doors. Doors of this type have a series of embossed designs simulating vertical and transverse slats stamped into the metal skin of the door panel to present the appearance of a carriage house door. However, due to the nature of the manufacturing process for such doors, the designs can not be changed or modified post production. In many cases, the homeowner desires a customized carriage house door adapted to their particular tastes and aesthetic presentation. This is very costly with known carriage house simulated steel garage doors, if possible at all.
Thus, an overhead garage door that is affordable, durable, low maintenance, impervious to weather and insects, and replicates the appearance of the historic swing type doors used in early automobile shelters and which is capable of being customized to satisfy specific design schemes is desired.
The various embodiments of this invention offer these and other advantages over known overhead door and panel designs. In one embodiment, this invention includes a number of horizontally oriented panels vertically stacked one upon the other in edge-to-edge relationship to simulate a carriage house door.
The panels are coupled to a track assembly mounted proximate the garage, warehouse or other opening. The track assembly includes a generally vertical section, a generally horizontal section and a curved transition section joining the horizontal and vertical sections together. Rollers are mounted on the panels and coupled to the track assembly to guide the door between a closed generally vertical configuration with the upper and lower edges of the adjacent panels mated together and an open generally horizontal configuration extending generally parallel to the ceiling of the garage or the like.
One aspect of this invention includes a door panel having a front skin presenting an exterior front face and an optional back skin presenting an interior back face. The skins in one embodiment are metal and the panels are filled with a foam or other insulating material. The panels each have mating upper and lower edges that mate the adjacent panels.
The front skin has a design stamped or embossed into the metal to simulate the vertical slats of a wooden carriage house door. The design may include any number of simulated vertical wood slats, in certain embodiments four to nine slats, and may be repeated on each door panel. The door panels and the resulting door may be customized with the addition of overlay members simulating a variety of designs, including the transverse or diagonal wood slats on traditional carriage house doors. The overlay members are selectively mounted to the front skin of the door panels at a variety of locations and orientations to mate with the design stamped or embossed into the front skin. In certain embodiments, the overlay members simulate a cross-buck pattern. The individual overlay members simulate a single transverse or diagonal slat or a pair such slats intersecting to form an X shape. The placement of the overlay members on one panel may be customized to particular tastes and coordinate with the appearance of the other panels of the overhead garage door.
As a result of this invention, the traditional carriage house style door is available with the benefits of modern steel sectional overhead doors and can be customized with the selective addition of overlay members simulating transverse wood slats complimenting the carriage house style motif.
The objectives and features of the invention will become more readily apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
Referring to
The adjacent panels 14 are pivotally connected together by a number of hinge assemblies 24. The hinges 24 proximate the lateral side ends of each panel 14 include a roller assembly 26 for coupling the door 10 to a track assembly 28. The opening and closing of the door 10 may be assisted by a counterbalance system 30 coupled to the door 10 as is well known in the art.
The track assembly 28, counterbalance system 30, hinge assemblies 24, top and bottom edge 16, 18 configurations and roller assemblies 26 shown in
Referring particularly to
The vertical slats are surrounded by a perimeter frame 46 which, in certain embodiments, includes a series of generally concave ridges 48 and convex grooves 50. While certain embodiments of the design 40 and associated components are shown herein, this invention is not limited to any particular design 40, frame 46, slat 42 or channel 44 configuration, arrangement or embodiment.
One feature of this invention is the selective addition of one or more overlay members 52 to the front skin 32 of selected panels 14 of the door 10. In various embodiments, the overlay member 52 simulates a single transverse slat 54 (
The overlay members 52 each mate with the design on the front skin 32 of the panel 14. Specifically, each overlay member 52 in some embodiments includes an upper and a lower edge 58, 60 each of which is sized and configured to mate with the perimeter frame 46 of the design 40 in certain embodiments. The upper and lower edges 58, 60 each include a protruding lip 62 which seats within one of the convex grooves 50 of the frame 46 to mate the overlay member 52 to the design 40. In this way, the overlay member 52 is positioned vertically on the front face 34 of the panel 14 in conjunction with the design 40. Advantageously, the overlay members 52 can be selectively positioned at a variety of locations or orientations on the panel 14. In one embodiment, the overlay member 52 can be mated horizontally at a variety of locations within the design 40 in that the lip 62 is capable of being seated in the convex groove 50 of the design 40 along substantially the entire longitudinal length of the frame 46. Moreover, one or more overlay members 52 can be mounted to the front skin 32 of the panel 14 to create a customized carriage house style facade to the overhead door 10 without the added expense of multiple different design configurations and arrangements formed in the front skin 32.
A variety of different attachment mechanisms 64 can be employed to mount the overlay members 52 to the front skin 32 of the panel 14, including adhesives, mechanical fasteners, interlocking mechanisms, snap fit engagement and combinations thereof. One example of such an attachment mechanism 64 is a mechanical fastener in the form of a push pin 66, canoe clip or the like as shown in
Another attachment mechanism is shown in
As a further alternative attachment mechanism 64, the post 78 and associated overlay member 52 may be heat staked to the front skin 32 of the panel 14. After the post 78 is inserted through the hole 80, the rearwardly protruding portion of the post 78 is melted into a mushroom-shaped cap 84 and the overlay member 52 is then staked to the front skin 32.
A further option for the attachment mechanism 64 is a double-sided high bond tape 86 as shown in
One advantage of this invention is the ability to provide compatible thermal expansion between the overlay member 52 and the front skin 32 of the panel 14. As such, one material which is suitable for the overlay member 52 is available from General Electric as GE Cycoloy® 4220. The coefficient of thermal expansion for the overlay member 52 is about 20.1×10−6 in/in/° F. and for the front skin is about 6.3×10−6 in/in/° F. This and other compatible materials for the overlay members 52 should be paintable, durable and have a comparable thermal expansion to the material of the front skin 32. Moreover, the overlay member 52 should accept an embossed pattern such as a wood grain texture or the like for compatible aesthetic appearance with any embossed wood grain pattern or the like on the front skin 32.
As a result of this invention, the traditional carriage house style door is available with the benefits of modern steel sectional overhead doors and can be customized with the selective addition of overlay members at a variety of positions, orientations and configurations to enhance and customize the aesthetic appearance of the door 10.
It should be readily appreciated that although certain embodiments and configurations of the invention are shown and described herein, the invention is not so limited. From the above disclosure of the general principles of the present invention and the preceding detailed description of various embodiments, those skilled in the art will readily comprehend the various modifications to which this invention is susceptible.
