1. Field of the Invention
Embodiments described herein generally relate to an apparatus and method for entering a garage or building through a sectional garage door when the sectional garage door is in a closed position. More particularly, the embodiments disclosed herein relate to an access door within the sectional garage door such that the access door allows access to the interior of the garage or building without opening the sectional garage door. More particularly still, the access door is adapted to pivotably move in a manner similar to the sectional garage door as the sectional garage door moves to and from a closed to an open position.
2. Description of the Related Art
In the construction of buildings, it is known to cover large access ways or openings into the interior of the buildings with sectional garage doors. For example, a residential garage for parking cars or a warehouse will include a sectional garage door which can be opened to allow access to the interior of the building. Sectional garage doors are commonly used in a variety of commercial, industrial, and residential applications. Sectional garage doors typically consist of a series of horizontal sections or panels which are connected to one another along a horizontal axis. The connection between horizontal sections is a hinged connection. The hinges allow the horizontal sections to pivot relative to one another about a horizontal axis. The pivoting allows the sectional door to flex as the sectional door is moved to and from a closed position to an open position.
Each of the horizontal sections spans the length of the entire opening in the building. Each end of the horizontal sections is coupled to one or more rollers. The rollers are adapted to roll within a track, located on each side of the horizontal sections, which guides the movement of the sectional garage door. The rollers are configured to guide and support the horizontal sections. Each track typically comprises a vertical portion, a bend, and a horizontal portion. The vertical portion follows the height of the building opening. Above the opening, the track bends from the vertical portion until it is substantially horizontal. The horizontal portion of the track is typically as long as the vertical portion. When the rollers are located in the vertical portion of the track, the horizontal sections or panels of the sectional garage door substantially cover the opening of the building. In this closed position, the building is inaccessible through the sectional garage door. The sectional garage door in this position is held in place by gravity pulling it down while the track and rollers prevent the horizontal sections from moving horizontally. In order to access the interior of the building the entire sectional garage door must be opened.
To open the sectional garage door, an operator, either manually or with an automatic opener, lifts the sectional garage door. As the sectional garage door moves up, the track guides the rollers thereby guiding the horizontal sections of the sectional garage door. As the rollers encounter the bend, the hinged connection allows each of the horizontal sections to pivot about a horizontal axis. The pivoting allows the substantially flat sectional garage door to pivot and conform to the track bend as the horizontal portions move past the bend. Once past the bend, the rollers are in line, in the horizontal portion of the track. With the rollers thus in line, the horizontal sections of the sectional garage door are substantially planar and are substantially horizontal. The rollers, supported by the track, support each end of the horizontal sections.
The sectional garage door only allows access to the interior of the building by moving the entire sectional garage door, thereby exposing the entire opening into the interior of the building. Sectional garage doors are often cumbersome and difficult to open. Further, if the interior of the building is climate controlled, opening the entire sectional door will cause the loss of the climate controlled air. Many buildings are not equipped with an alternative entrance other than the sectional garage door. Thus, if an individual wants to enter the interior of the building, the individual must open the entire sectional garage door to gain entry.
Therefore, there is a need for an entry into the interior of a building through a sectional garage door, without opening the sectional garage door. There is a further need for an access door adapted to open within the sectional garage door to allow an individual to enter without opening the sectional garage door. There is a further need for an access door which is adapted to open when the sectional garage door is closed and to pivotably move with the sectional garage door as the sectional garage door travels to and from an open and closed position.
Embodiments described herein generally relate to an access door for use within a sectional garage door. The access door includes two or more door panels, and a first set of hinges. The first set of hinges pivotably couple each door panel to a door frame. The door frame is coupled to the sectional garage door and the first set of hinges enable the access door to pivot from a first position substantially coplanar to the sectional garage door to a second position extending at an angle from the sectional garage door. The access door further includes a second set of hinges. The second set of hinges are located between two abutting door panels and configured to pivot the door sections about a substantially horizontal axis as the sectional garage door moves between a closed position and an opened position.
So that the manner in which the above recited features of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings. It is to be noted, however, that the appended drawings illustrate only typical embodiments of this invention and are therefore not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments.
The sectional garage door 104 may include a door frame 206 for supporting an access door 208 as shown in
In one embodiment, the hinges 400 and/or the horizontal hinges 500 may be spring loaded or biased. Thus, the hinges 400 would be biased to move the access door 208 toward the closed position, shown in
Although the door sections 300 are shown hinged directly to the door frame 206, it should be appreciated that the door sections 300 may be coupled directly to the horizontal panels 200. In this embodiment, the door frame 206 is not required.
The access door 208 may include a handle 304, as shown in
The sectional garage door 104 may include rollers 700, shown in
In one embodiment, the sectional garage door 104 has a controller 800. The controller 800 may be adapted to control the sectional garage door 104 and/or the access door 208. Further, the controller may be a safety mechanism. The controller may be programmable and contain a mass storage device. The access door 208 may be provided with a contact 802, shown schematically. The contact 802 is in communication with the controller 800, via communication path 804. The communication path 804 may be a wired or wireless communication path, such as inferred, blue tooth, etc. The contact 802 sends a signal to the controller 800 which indicates whether the access door 208 is in the closed or the open position. In one embodiment, the controller 800 is programmed to prevent the sectional garage door 104 from opening when the access door 208 is not in the closed position. The controller 800 may be in communication with a first opener 805, via communication path 804, for opening and closing the sectional garage door 104 and/or a second opener 807 for opening and closing the access door 208. The second opener 807 may be in communication with the latch of the handle 304 at the access door 208. Thus the second opener 807 may release the latch and open the access door 208. The controller 800 is adapted to receive signals from a control panel 806. The control panel 806 may be in wired or wireless communication with the controller 800. The control panel 806 may be adapted to be secured to the interior/exterior of the building 100, and/or be remotely located, for example in a car. The control panel 806 sends a control signal to the controller 800. The controller 800 then performs the task required by the signal. The control panel 806 may include two buttons, a first button 808 for operating the sectional garage door 104 and a second button 810 for operating the access door 208. Thus, an operator may open and close the access door 208 remotely by pushing the second button 810. The operator may then push the first button 808 in order to open the sectional garage door 104. If the access door 208 is in the open position when the operator pushes the first button 808, the controller 800 may prevent the sectional garage door 104 from moving. The controller 800 may further be adapted to send a signal to a security system when either the access door 208 and/or the sectional garage door 104 are not in the closed position.
In an alternative embodiment, a mechanical lock out device (not shown) is provided for preventing the sectional garage door 104 from opening when the access door 208 is not closed. The mechanical lockout device may include lock, such as a bar or rod, that intersects an aperture (not shown) in the track 106, similar to a traditional sectional garage door lock. The lock could have an actuator coupled to the door frame 206. When the access door 208 opens the actuator pushes the lock through the aperture, thereby preventing the sectional garage door 104 from opening. In yet another alternative embodiment, mechanical lock may be a rod or bar that intersects at least one of the horizontal axis 202 between the horizontal panels 200 when the access door 208 is in the open position. Further, any mechanical device for preventing the sectional garage door 104 from opening when the access door is open may be provided.
The access door 208 may be manufactured with the sectional garage door 104 as one unit. Further, the access door 208 may be retrofitted on any existing sectional garage door 104. This allows a user to add an access door 208 to a building 100 without having to modify the structure of the building 100.
In operation, the access door 208 and sectional garage door 104 are installed into the building. A user may approach the building 100 from the exterior of the building 100 when the opening 102 is obstructed by the sectional garage door 104 and the access door 208. If the user chooses to enter the building 100 without opening the sectional garage door 104, the user may use the access door 208. The user may use the control panel 806 to automatically open the access door 208 using the second opener 807, or manually manipulate the handle 304 to open the access door 208. As the user, or the second opener 807, moves the access door 208, the hinges 400 allow the access door 208 to pivot about the vertical axis 302 relative to the sectional garage door 104. The continued pivoting of the access door 208 creates the passage 209. The user may then walk through the passage 209 and gain access to the interior of the building 100. Because the passage 209 is relatively small compared to the opening 102, the loss of climate controlled air in the building is minimal. The user may close the access door 208, thereby preventing the elements or other people access to the interior of the building 100. With the access door 208 closed, the user may open the sectional garage door 104. The user, either manually or using the first opener, may lift the sectional garage door 104. As the sectional garage door 104 moves up, the rollers 700, coupled to the horizontal panels 200, guide the horizontal panels along the track 106. The uppermost rollers 700 then encounter the bend in the track 106. The bend allows the rollers 700 to transition from the vertical section to the horizontal section of the track 106. As the rollers 700 encounter the bend, the horizontal panels 200 pivot relative to one another about each of the horizontal axis 202. The pivoting of the horizontal panels 200 causes the horizontal hinges 500 to pivot, thereby allowing the door sections 300 to pivot and move with the horizontal panels 200. Each of the horizontal panels 200 and door sections 300 pivot around the bend in the track 106 until the sectional garage door 104 is in the open position. Once in the open position, the user may move large equipment into and out of the building 100. The process may be repeated in order to close the sectional garage door 104. Further, the steps in the process may be in any order depending on the requirements of the user.
In an alternative embodiment, the sectional garage door 104 includes an oversized passage 900 which houses an oversized access door(s) 902. The oversized access door(s) 902 operate in a similar manner to the access door 208 described above; however, the oversized access door(s) 900 is adapted to create a larger opening in the sectional garage door 104. As shown in
In an alternative embodiment, the access door 208 or 902 is replaced with a roll up access door 1000, as shown in
In yet another embodiment, the access door 208 is a Dutch door (not shown). The Dutch door allows the opening of only the top half or only the bottom half of the door 208.
In yet another embodiment, the sectional garage door 104 includes more than one access door 208 and/or 902.
The access door 208 and sectional garage door 104 may include standard door items, including but not limited to molding (not shown), ornamentation (not shown), windows (not shown), etc.
In an alternative embodiment, the access door 208 may have a separate screen door (not shown). The screen door would prevent insects from entering through the passage 209 when the access door 208 is in the open position. The screen door may be a roll up screen attached to one side of the door frame 206 or a conventional screen door. The conventional screen door would require a hinge or flexible joint near the flexible joint 210 of the door frame 206. Further, the screen door would have hinges which attach the screen door to the door frame 206 in a manner similar to the hinges 400.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
