Description
- The invention relates to industrial doors, in particular segmented rigid-panel doors which are accumulated overhead when in the open position.
- Overhead doors have been used for many years to secure various enclosures including manufacturing plants, warehouses, garages, and other industrial doorways that require a heavy duty cycle. Such doors are generally comprised of articulated, joined panels or slats. Generally, such overhead doors are guided by tracks along door jambs, facilitating movement of the door between open and closed positions. The guide tracks used with slat-type or segmented panels generally extend upwardly above the door opening for storing the door when in an opened position. In places where overhead space is insufficient, the track may guide the door at a backward angle above the door opening.
- Recently, however, it has been proposed to accumulate the door panels above the door by guiding the panels into an overlapping, coiled or spiraled configuration. Such overhead doors have been guided for movement up and down by guide tracks consisting of essentially three basic portions. Examples of such overhead doors are disclosed in U.S. Patent Nos. 5,484,007 and 5,394,924. The first portion of the guide tracks extend vertically along the sides of the door or jambs. The second portion of the guide tracks extends above the opening, turns horizontally at the top of the doorway, and extends away from the wall. The third portion of the guide tracks forms an inward coiled configuration which encircles a door drive motor. Accordingly, as the door is lifted, it is guided along the guide tracks and directed into the coiled configuration. While these overhead doors have enjoyed a great deal of success, they have also presented various problems as will be discussed herein.
- In particular, problems exist in the ability of the door to withstand impact without sustaining debilitating damage to the door and its associated guide structure. Because overhead doors are generally used to secure industrial areas with high traffic, the door is often not completely open before attempted transit through the doorway by vehicles such as forklift trucks. Accordingly, at least the bottom-most panels are subjected to impact by these vehicles. Therefore, at least one or more of the bottom-most panels of the door must be able to withstand frontal impact without sustaining severe damage to the entire door or its associated jambs. Replacement of the overhead door or panels can be costly and can also result in increased down-time.
- Additionally, doors, such as those disclosed in U.S. Patent Nos. 5,484,007 and 5,394,924, employ a chain of interconnecting hinges to lift the door between opened and closed positions. The hinges are strap-like and are mounted to only one face of a respective panel. Problems exist with respect to the ability of hinge straps to adequately distribute forces which are created during movement of the door. The straps overlap an end portion of the slats and are bolted thereto. The hinge straps typically consist of thin formable metal. Each hinge has a male end and a female end created by rolling the ends of the metal into loops. The mated loops are rotatably secured by hinge pins. In overhead doors using such hinges, the distribution of force created by movement of the door can cause the hinges to wear prematurely or be damaged. In particular, the stresses applied to the interconnected loops, created by repeated opening and closing of the door can cause the ends to become "unrolled." Additionally, the male and female portions cannot generally be centered to the middle of a door panel as centering the portions requires that the metal be extended at an angle inwardly from a face of the panel, where the main body of the strap-type hinge is secured. Bending the metal may result in increased stresses at the angle of the metal. Thus, there is a need for a stronger panel-hinge assembly that can accommodate doors having a large duty cycle.
- Another problem with previous overhead doors is the configuration of the overhead guide track. Typically, when the overhead door is being serviced for maintenance, it is desirable to keep the door in an overhead position to allow continued use of the doorway or opening. However, in previous overhead guide configurations, the motor and much of the associated drive apparatus are surrounded by the door panels when the door is in its overhead position. Such configurations make access to the motor and associated drive difficult. These configurations also require that the door be at least partially disassembled if repair or replacement of the motor or its parts is necessary. Disassembly of the door can ultimately result in non-use and increased down-time of the door. Consequently, there is a need for an overhead accumulation configuration that does not impede access to the motor assembly and associated apparatus.
- The present invention is provided to solve these and other problems and provide advantages and aspects not provided by prior doors of this type.
- The present invention provides an overhead rigid-panel door which is selectively movable up and down to open and close an opening and is accumulated overhead in a coiled-type configuration.
- According to one aspect of the present invention, a door is provided which has a pair of chains for movement of a plurality of rigid panels up and down. The chains are disposed between the panels and door guides at opposed sides of the door. Each chain comprises a plurality of interconnecting hinges. The panels each have a first end and a second end and are of sufficient length to extend substantially across the opening, but sufficiently limited in length to fit between the first and second chains and not extend beyond them. The door also includes a means for connecting each door panel to a separate pair of hinges at the first and second ends of each panel.
- According to another aspect of the present invention, a door is provided which includes a door body having a plurality of panels hingedly connected together. The door includes a door guide having a first portion which guides the door panels vertically, a second portion which guides the door panels at an angle to the vertical, and a third portion which directs the door body into an overlapped or coiled configuration for storage when the door is in an open position. The door in the present invention further includes a motor which moves the door body along the door guide thereby opening and closing the door. The door panels in an accumulated position are situated so that a space exists between the first panels and the first door guide portions. The present invention requires that the space be of sufficient size to accommodate locating at least the motor therein so the door does not obstruct access to the motor from at least one direction when the door body is accumulated overhead into the coiled configuration.
- According to yet another aspect of the present invention, a method of making a hinge is provided. The method includes defining a desired hinge thickness, height and profile as viewed from a cross section through the thickness. The method also requires using an extrusion mold, which will extrude elongated stock, having the desired thickness, height and profile as viewed through the cross-section or the thickness. The method further requires cutting or otherwise dividing the extruded length into the desired width. Finally, the method requires removing unwanted material at one end of the height of the hinge to define a male mating portion and two spaced extending portions at the other end of the hinge to define a female mating portion.

- While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspects of the invention to the embodiments illustrated.
- FIGS. 1-9 disclose an improvement on previous overhead rigid-panel door and hinge assemblies. According to one aspect of the present invention, a
door 1 which is selectively moved up and down to open and close an opening (not shown) and which is guided along side guide tracks 4 at the edge of the opening is disclosed. As shown in FIGS. 1 and 2, the overhead door I generally includes a plurality ofpanels 6, a pair ofchains 8 defined by interlinked hinges 10, and a means for connecting eachpanel 6 to a separate pair of hinges 10. - FIG. 1 illustrates a plurality of
panels 6, each having a first end 12 and a second end 14. Eachpanel 6 is of sufficient length to extend substantially across the opening, but sufficiently limited in length so as to fit between and not extend across thechains 8 on opposed sides of the opening. Eachdoor panel 6 generally abuts the tworespective hinges 10 with which it is associated. - FIGS. 1-4 show the
chains 8 which move thepanels 6, and therefore thedoor 1, up and down. Thechains 8 are defined by interlinked hinges 10 and are disposed between thepanels 6 and the guide tracks 4. Each of thehinges 10 which comprise thechain 8 is pivotal about ahinge pin 18. Each of thehinges 10 has twoends 19a and 19b. The first end 19a of eachhinge 10 has an extendingmale portion 20 with a through-hole 22 for receiving thehinge pin 18. Thesecond end 19b has a pair of spaced extendingportions 24a and 24b defining afemale portion 24. Each of the extendingportion 24a, 24b of thefemale portion 24 also has a through-hole 22 for receiving ahinge pin 18. The through-holes 22 of both the male 20 and female 24 hinge portions are aligned so that they are generally centered between a front surface (see FIG. 2) and a back surface (not shown) of thepanels 6 for improved force distribution. - FIG. 1 and FIG. 2 illustrate the means for connecting the
panel 6 to its respective two hinges 10. The means for connecting at least the bottom-most panel to its respective two hinges 10 includes connectinginserts 9. The connectinginserts 9 permit separation of thepanel 6 from thehinges 10 upon an impact to thepanel 6 in excess of a predetermined force, as will be explained below. - As shown in FIG. 1 and FIG. 2, the door guide requires at least some of the hinge pins 18 to extend to the door guides 4. Each of the hinge pins 18 that are extended have a
roller 26, rotationally engaged proximate the extended ends of the hinge pins 18. Eachroller 26, in turn, engages the door guide 4 (FIGS. 8 and 9). - In the preferred embodiment, the
hinges 10 are structurally biased to rotate in only one direction and to resist rotation in the opposite direction. The hinges 10 rotate between a straight in-line position when thedoor 1 is closed, to an angled position when thedoor 1 is accumulated overhead. As may be seen in FIGS. 3 and 4, the structural bias is provided by terminating the male 20 and female 24 extending portions with arounded shoulder 30 toward a side to which rotation is desired, and providing asquared shoulder 32 toward the opposite side where rotation is not desired. - In the preferred embodiment, the
door panels 6 include receptacles 33 (now shown) formed in each of the first and second ends, 12 14 of eachpanel 6, and each hinge 10 has areceptacle 34 being formed in its body. Also in the preferred embodiment, the connectinginserts 9 havefirst end 13a, asecond end 13b and acenter portion 15. Thefirst end 13a of the connectinginsert 9 is secured by suitable means in thereceptacle 34 of thehinge 10. Likewise, thesecond end 13b is secured by suitable means in thereceptacle 34 of one of the ends 12, 14 of thepanel 6. The means for securing the insert, may be bolts, pins, or any device suitable for securing two members. - The connecting
inserts 9 between at least thebottom-most panel 6 and its tworespective hinges 10 is sacrificially broken at the thinnedportion 15a of theinsert 9 when thepanel 6 is impacted by a force in excess of a predetermined force. This permits thepanel 6 to separate from thehinge 10, reducing damage to thehinges 10 or thedoor 1. As shown in FIG. 5 and 6, a preferred method of weakening this area is simply to cut slots 21 a, 21b into thecenter portion 15 to a depth which will give the desired predetermined force for separation. It is contemplated that the connectinginsert 9 can be configured to cause the door to separatedoor panel 6 fromhinges 10 in other ways. For example, a connectinginsert 9 made of a material, such as rubber, may be used so that when impacted, the material flexes to dislodge from either thereceptacles 34 or 33. - Another aspect of the present invention is shown in FIGS. 7-9 in which the
door 1 is guided by door guides 4 and accumulates overhead when in an open position. FIG. 8 shows the door guide 4 having afirst portion 38, asecond portion 40, and athird portion 42. Thefirst portion 38 of the door guide 4 guides thedoor 1 vertically while thesecond portion 40 guides the door horizontally. Thethird portion 42 directs thedoor 1 into a coiled configuration for storage when thedoor 1 is in an open position. - As can further be seen in FIG. 8, a
motor 39 is operably connected to thedoor 1 to move the door I along the door guide 4. The accumulatedpanels 6 are situated so that there exists aspace 44 between thefirst guide portion 38 and thepanels 6. Thespace 44 is of sufficient size to accommodate access to themotor 39 from at least one direction when the door I is accumulated into the coiled configuration. - In the preferred embodiment the coiled configuration extends horizontally away from the door opening. However, it is contemplated that the coiled configuration may extend away from the door opening at any angle in which the
motor 39 may still be accessed inspace 44 when thepanels 6 are accumulated into the coiled configuration. It is further contemplated that "coiled" herein merely means that thedoor guide 36 coils "back on itself" regardless of how many times, and is not meant to be constrained to spirals, circles or any other particular geometric shape. - Conventional hinges are configured to attach to either faces or adjoining edge surfaces of the two entities to be hinged together, for example see U.S. Patent Nos. 5,484,007 and 5,394,924. However the
hinges 10 of the present invention are uniquely configured to be located on the end surfaces of the twopanels 6 which are to be hinged together. While thedoor 1 is shown usinginserts 9 for connection, other means for connecting the ends ofpanels 6 to a hinge according to the invention could be used such as conventional fasteners (bolts, screws, glue) used in connection with flanges, brackets or other well known means to connect the side of the hinge to an end of a panel. - According to another aspect of the invention, the
hinges 10 can be advantageously manufactured by defining a desired hinge thickness 46, height 48 and profile as viewed from a cross section through the thickness 46. Secondly, using an extrusion mold which will extrude elongated stock having the desired thickness 46, height 48 and profile as viewed through a cross section of the thickness 46. Thirdly, cutting or otherwise dividing the extruded length into the desired width 50 for the hinge. Finally, removing unwanted material to form an extended portion at one end of the height 48 of the hinge to define amale mating portion 20 and at the other end of the height 48 to define afemale mating portion 24. The removal of unwanted material may be done on the bar stock prior to cutting the extrusion into separate hinges 10. One can also provide an extrusion mold with means to extrude the through-holes 22 forhinge pin 18 connection between hinges 10. Alternately the through-holes 22 may be formed by boring or drilling either after defining theextended male 20 and female 24 portions, or before removing the unwanted material to define those portions. Preferably, the mold may also be equipped with means to provide a hollowed center in the profile of thehinge 10 and extrudate as viewed in cross section through the thickness 46. The hinges 10 of thedoor 1 are preferably made in the above manners from aluminum. - While the specific embodiments have been illustrated and described, numerous modifications come to mind without significantly departing from the spirit of the invention and the scope of protection is only limited by the scope of the accompanying Claims.
