The present invention relates to automatic sliding door systems.
Retail stores in the United States commonly use automatic sliding doors, which consist of a right door and a left door that slide along a sliding plane from a sliding closed position to a sliding open position when, for example, a motion sensor detects a shopper or employee. Fire code regulations generally require that such doors break open outward to allow egress of shoppers or employees from the store in the event of a fire. Such sliding doors typically only break open outward—not inward and hence are referred to herein as single breakout sliding doors.
While such systems are generally designed for the safety of pedestrian traffic, the movement of large or heavily loaded equipment often puts the door at risk of being damaged especially when moving such equipment into the store. Thus, sliding doors that break open outward and inwardly (referred to herein as double breakout sliding doors) are desired in some instances.
In prior art door systems, when a door breaks open outward, the bottom corner of the door that meets the other door when the doors are closed (also referred to as the nose) drops on the ground. This can be problematic in that the doors, which are heavy, must be raised to reset the normal sliding operation of the doors.
The present disclosure provides a sliding door system as described herein. In some embodiments, the sliding door system is a double breakout sliding door system. In other embodiments, the sliding door system is a single breakout sliding door system. Preferably, the sliding door systems allow adjustment of the doors to prevent the nose of the doors from dropping when breaking open outward (referred to herein as the front open position) and inward (referred to herein as the rear open position).

The double breakout sliding door system 10 optionally further includes a top left panel 44 (known in the art as a “carrier”) located above the left door 24, the top left panel 44 connected to the left door 24 and comprising a top left panel left side 45, a top left panel right side 47, a top left panel width 49 extending from the top left panel left side 45 to the top left panel right side 47, a top left panel top 46, a top left panel bottom 48 located below the system frame top 14 and the system frame opening 23, a top left panel height 50 extending from the top left panel top 46 to the top left panel bottom 48, a top left panel front side 52, a top left panel rear side 54, and a top left panel 56 thickness extending from the top left panel front side 52 to the top left panel rear side 54, the top left panel height 50 parallel to the left door height 42 when the left door 24 is in the sliding plane and perpendicular to the left door thickness 30 and the top left panel thickness 56 and the top left panel width 49. The top left panel 44 may be comprised of two or more discrete parts (e.g., a block 136 mounted on top of a top left panel frame piece 138, which may be for example comprised of extruded aluminum) and may have a variable height 50, as best seen in
The double breakout sliding door system 10 optionally further includes a top right panel 134. The top right panel 134 is optionally a mirror image of the top left panel 44, except for the top lock 128, for example, as later described. Given the duplicity of the components and design, the parts of the top right panel 134 are not numbered in the drawings.
The double breakout sliding door system 10 optionally further includes a motor 58.
The double breakout sliding door system 10 optionally further includes a left rod 60 having a left rod top 66 pivotally attached to the top left panel 44 by a left pivot pin 62 forming a left pivot pin axis 64 and a left rod bottom 68 attached to the left door left side 32, the left rod 60 extending in a general downward direction from the top left panel 44 at least partially through the left door 24. The left rod 60 optionally is generally cylindrical in shape. It will be understood that the left pivot pin 62 and left pivot pin axis 64 do not have to be at the very top end of the left rod 60 and that the attachment point of the left rod 60 to the left door 24 does not have to be at the very bottom end of the left rod 60—rather the left pivot pin 62 and left pivot pin axis 64 are attached to the left rod top 66 (i.e., attached adjacent to the top end of the left rod 60) and the attachment point of the left rod 60 to the left door 24 is at the left rod bottom 68 (i.e., adjacent to the bottom end of the left rod 60). As best seen in
The double breakout sliding door system 10 optionally further includes a right rod (not shown). The right rod is optionally a mirror image of the left rod 60. Given the duplicity of the components and design, the right rod parts are not numbered in the drawings.
Optionally, the motor 58 is configured to slide the left door 24 and right door 130, i.e., move the left door 24 and right door 130 horizontally along a sliding plane parallel to the system frame width 22, from a sliding open position in which the left door 24 and right door 130 are apart and do not close the system frame opening 23 (as illustrated in
Optionally, the top left panel 44 is configured to slide with the left door 24 from the sliding open position to the sliding closed position and the top right panel 134 is configured to slide with the right door 130 from the sliding open position to the sliding closed position.
Optionally, the left door 24 is configured to pivot (e.g., rotate) about the left rod 60 from the sliding plane to a left door front open position (as illustrated in
Optionally, the right door 130 is configured to pivot similarly.
Optionally, the bottom 40 of the left door right side 34 is configured to remain at substantially the same height (and level relative to the ground and the top left panel 44) when the left door 24 pivots about the left rod 60 from the sliding plane to the left door front open position and to the left door rear open position and the right door 130 is similarly configured to remain level. Thus, the left door 24 breaks open in two directions while remaining level relative to the top left panel 44 and the ground. (As explained in the Background, the prior art systems are primarily designed to break open in one direction—not two—and the prior art systems typically allow the nose of the door (the bottom of the left door right side) to touch the ground when breaking open).
Optionally, the left door 24 and top left panel 44 interlock through the use of mating latches 71 and 82 when the left door 24 is in the sliding plane. (This interlocking latch feature in addition to the left rod 60 supports the left door 24 when the left door 24 is in the sliding plane). More particularly, in some embodiments, the left door 24 further comprises a left door top latch 71 attached to the left door 24 via latch fasteners 73. The left door top latch 71 is adjacent (i.e., at or near) the left door right side 20 and the left door top latch 71 has a left door latch base 72 that has a left door latch base bottom 74 attached to the left door top 38 and a left door latch base top 75. The left door top latch 71 further includes a left door latch flange 76 that is located above the left door latch base 72 and includes a left door latch flange bottom 77, a left door latch flange top 78 and a left door latch flange height 79 extending from the left door latch flange bottom 77 to the left door latch flange top 78. The left door top latch 71 further includes a left door latch slot 80 that is located between the left door latch base 72 and the left door latch flange 76 and that has a left door latch slot height 81 extending from the left door latch base top 75 to the left door latch flange bottom 77. In such embodiments, the top left panel 44 further comprises a top left panel bottom latch 82 attached to the top left panel 44 via latch fasteners 73. The top left panel bottom latch 82 is adjacent (i.e., at or near) the top left panel right side 47 and the top left panel bottom latch 82 has a top left panel latch base 83 that has a top left panel latch base top 85 attached to the top left panel bottom 48 and a top left panel latch base bottom 84. The top left panel bottom latch 82 further includes a top left panel latch flange 86 that is located below the top left panel latch base 83 and includes a top left panel latch flange bottom 87, a top left panel latch flange top 88 and a top left panel latch flange height 89 extending from the top left panel latch flange bottom 87 to the top left panel latch flange top 88. The top left panel bottom latch 82 further includes a top left panel latch slot 90 that is located between the top left panel latch base 83 and the top left panel latch flange 86 and that has a top left panel latch slot height 91 extending from the top left panel latch base bottom 84 to the top left panel latch flange top 88. The top left panel bottom latch 82 may be located in a cut-out of the top left panel 44, as best seen in
The double breakout sliding door system 10 optionally further includes a ball detent mechanism to alert the user that the latches 71 and 82 are properly aligned—i.e., the left door latch flange 76 is nested in the top left panel latch slot 90 and the top left panel latch flange 86 is nested in the left door latch slot 80. For example, the left door 24 and the top left panel 44 may include a ball detent comprising a ball 94, a recess 96 configured to receive the ball 94, and a spring 98 connected to the ball 94 and configured to urge the ball 94 toward the recess 96, and the ball 94 is configured to move into the recess 96 when the top left panel latch flange 86 is nested in the left door latch slot 80 and the left door latch flange 76 is nested in the top left panel latch slot 90.
Optionally, the left rod bottom 60 is configured to be the sole point of attachment of the left door 24 to the top left panel 44 when the left door 24 is in the left door front open position and the left door rear open position, as best seen in
Optionally, the left pivot pin axis 64 is perpendicular to the system frame front side 7 and system frame rear side 8.
Optionally, the top left panel 44 further comprises a left adjustment fastener 100 configured to engage the left rod 60 and cause the left rod 60 to pivot along the left pivot pin axis 64, as best seen in
Optionally, the left door 24 comprises a frame 102 and a transparent or semi-transparent material (e.g., glass or plastic)—i.e., a window. The left door frame 102 may include a left door frame interior 104 and the left rod 60 may be located within the left door frame interior 104. Again, the right door 130 may have similar features. Optionally, the bottom 68 of the left rod 60 is hollow and surrounds a threaded shank 110 of a left threaded bolt 106 that includes a head 108 and the threaded shank 110, wherein the left rod 60 is fixed to the threaded shank 110 of the left threaded bolt 106, wherein the left door 24 further comprises a left door bracket 112 located between the head 108 of the left threaded bolt 106 and the left rod bottom 68, wherein the left door bracket 112 is attached to the left door frame 102, wherein the left door bracket 112 is configured to rotate about the left rod 60 and the left threaded bolt 106 while the left rod 60 and the left threaded bolt 106 remain stationary as the left door 24 moves from the sliding plane to the left door front open position and the left door rear open position. Again, the right door 130 can include similar features. Bolts can be any suitable material, including for example, metal or nylon. The double breakout sliding door system 10 optionally further includes a left fastener 113 fixing the left rod 60 to the threaded shank 110 of the left threaded bolt 106. A right fastener may also be included for the right door 130. Optionally, the left door frame 102 forms a perimeter around a plurality of left door glazing blocks 114 (e.g., glass blocks) and the plurality of left door glazing blocks 114 are located between the left door frame 102 and a left door glazing panel 116, as shown in
The double breakout sliding door system 10 optionally further includes a door lock 126 comprising a bar or hook extending from the left door 24 to the right door 130 and configured to fix the left door 24 relative to the right door 130. Optionally, the system 10 further includes at least one top lock 128 comprising a bar extending from the top of a door 24 or 130 to the bottom of a top panel 44 or 134 and configured to fix the door 24 or 130 relative to the top panel 44 or 134.
The double breakout sliding door system 10 optionally includes a left track 120 located above the top left panel 44 and a left wheel 122 connected to the top left panel 44 and located in the left track 120 and the left wheel 122 is configured to move along the left track 120 when the top left panel 44 and the left door 24 slide from the sliding closed position to the sliding open position. The right door 130 may include similar features. Optionally, the motor 58 is configured to move the left wheel 122 along the left track 120. It will be appreciated that references herein to the singular embrace the plural. Thus, the double breakout sliding door system 10 may include one or more left wheels 122.
The double breakout sliding door system 10 optionally further includes one or more motion sensors 124 (preferably two motion sensors that are adjacent to the system frame front and rear sides 7 and 8) in electronic communication with the motor 58 and configured to cause the left door 24 and the top left panel 44, the right door 130 and the top right panel 134 to move from the sliding closed position to the sliding open position when the sensor 124 detects an object, such as a human or shopping cart, in front of or to the rear of the left door 24 and the right door 130.
The double breakout sliding door system 10 optionally further includes a left door panel 118 configured to remain fixed relative to the rectangular door system frame 12 when the left door 24 moves from the sliding closed position to the sliding open position, the left door panel 118 located to the left of the left door 24 when the left door 24 is in the sliding closed position. In such a case, the left door 24 is configured to slide to the rear of the left door panel 118 when the left door 24 slides from the sliding closed position to the sliding open position, the left door panel 118 is configured to move with the left door 24 when the left door 24 moves from the sliding plane to the left door front open position, and the left door panel 118 is configured to remain fixed relative to the rectangular door system frame 12 when the left door 24 moves from the sliding plane to the left door rear open position. A right door panel 134 having similar features may also be included.
Although the left door 24 and right door 130 may include a door lock 126 and top lock 128, there may be no similar locking system on the left door panel 118. Thus, the double breakout sliding door system 10 optionally further includes a left door panel interlocking device located on the rear 28 of the left door 24 which hooks into the left door panel 118 thereby preventing the left door panel 118 from being opened when the left door 24 is in the sliding closed position, regardless of whether the door lock 126 and top lock 128 are engaged. If one was to attempt to move the left door 24 from the sliding closed position to the rear open position, the left door panel interlocking device would actually bind up inside the left door panel 118 preventing the left door 24 from fully moving to the rear open position. So, there is a timing issue at stake here. In order for the left door 24 to move to the rear open position in embodiments with a left door panel interlocking device, the left door 24 must not be in the sliding closed position (i.e., the left door 24 must be in the sliding plane at either the sliding open position or between the sliding closed position and the sliding open position) to disengage the hook of the left door panel interlocking device (open at least one inch for example). Because this is an automatic door with a motion sensor 124, the motion sensor 124 will have detected any person or other object (and have caused the left wheel 122 and motor 58 to move the left door 24 in the sliding plane to either the sliding open position or between the sliding closed position and the sliding open position) before the object can get close enough to the left door 24 to touch it. Therefore, the left door 24 will always be at least slightly slid open (i.e., between the sliding open position and the sliding closed position) by the time a force is exerted on the left door 24 perpendicular to the left door front side 26 and left door rear side 28. As a result, the left door panel interlocking device does not impede the left door 24 from moving to the left door rear open position when the motor 58, motion sensor 124 and left wheel 122 are working correctly.
Optionally, moving the left door 24 from the sliding plane to the left door front open position and the left door rear open position is configured to disable the motor 58, as a safety feature. (Again, the same may be true with the right door 130 as it moves from the sliding plane to the right door front open position and the right door rear open position). To disable the motor 58, the double breakout sliding door system 10 may include a rear breakout sensor 142 that detects presence and is triggered when the left door 24 moves to the rear open position to disable the motor 58. (In some embodiments, the rear breakout sensor 142 is an infrared sensor that includes a transmitter that transmits the infrared beam and a receiver that receives the infrared beam, similar to the infrared setup used on a garage door. When the receiver no longer receives the beam, it knows that the left door 24 is in the left door rear open position and disables the motor 58). Similarly, to disable the motor 58 when the left door 24 moves to the left door front open position, there may be a front breakout senor 144 located in the left door panel 118 that detects when the left door 24 moves to the left door front open position.
More particularly, the system 200 includes a rod 208, which may have a rod top 210 pivotally attached to the top panel 206 by a pivot pin 212 forming a pivot pin axis 214 and a rod bottom 216 attached to the door 202 (e.g., the door left or right side) and a rod longitudinal axis 218 extending from the rod top 210 to the rod bottom 216. The rod 208 may extend in a generally downward direction from the top panel 206 at least partially through the door 202. The pivot pin 212 may be transverse to the rod longitudinal axis 218 and attached to the top panel 206. (If two doors 202 are used, each door 202 may be attached to a rod 208, and each rod top 210 may be attached to a top panel 206).
Optionally, when the door 202 moves from the sliding plane to the door front open position when a force is exerted on the door rear side 222 perpendicular to the door rear side 222 when the door 202 is in the sliding plane, i) the door 202 is configured to rotate around the rod 208 about a rotational plane generally perpendicular to the rod longitudinal axis 218, ii) the door 202 is configured to rotate relative to the top panel 206 and iii) the rod 208 is configured to remain stationary relative to the top panel 206.
Optionally, the bottom 224 of the door side opposite the rod 208 (i.e., the right side as shown in
Optionally, the top panel 206 further comprises an adjustment fastener 232 configured to engage the rod 208 and cause the rod 208 to move about the pivot pin axis 214 in a plane generally perpendicular to the rotational plane. Optionally, moving the rod 208 about the pivot pin axis 214 is configured to cause the bottom 224 of the door side opposite the rod 208 (e.g., the right side as shown in
Optionally, the rod bottom 216 is hollow and surrounds a threaded shank of a threaded bolt comprising a head and the threaded shank and the rod 208 is fixed to the threaded shank of the threaded bolt. The threaded bolt, threaded bolt head and the threaded bolt shank are not specifically shown in
Optionally, the system 200 further comprises a door top latch 246 extending from the door top 248, a top panel bottom latch 250 extending from the top panel bottom 252, the door top latch 246 and the top panel bottom latch 250 are configured to mate when the door 202 is in the sliding plane and the door top latch 246 and the top panel bottom latch 250 are not configured to mate when the door 202 is in the door front open position. Optionally, the top panel bottom latch 250 is configured to support the door 202 when the door 202 is in the sliding plane and the top panel bottom latch 250 is not configured to support the door 202 when the door 202 is in the door front open position. The door top latch 246 and the top panel bottom latch 250 are best seen in
Optionally, the door bottom 224 further comprises a door bottom lock 270 having a locked position in which the door bottom lock 270 prevents the door 202 from moving from the door 202 sliding plane to the door front open position and also prevents the door 202 from moving from the sliding closed position to the sliding open position and an unlocked position in which the door bottom lock 270 allows the door 202 to move from the door sliding plane to the door front open position and to move from the sliding closed position to the sliding open position. A purpose of the bottom lock 270 is that it can be used in events of extreme weather such as a hurricane to provide further protection. Optionally, a shield 272 is used to prevent a user from accidentally kicking and engaging the bottom lock 270.
Optionally, the door 202 further comprises a depressible panic bar 274 operatively connected to the bottom lock 270 and the top lock 280 (which is described below). Depressing the panic bar 274 is configured to rotate gear 278, moving top lock rod 282 downwardly and bottom lock rod 276 upwardly, and thereby cause the top lock 280 to move from the locked position to the unlocked position and cause the door bottom lock 270 if the bottom lock pin tip 292 is in the bottom lock recess 294 to move from the locked position to the unlocked position. The connectivity is seen in
An example of the bottom lock 270 is best seen in
Optionally, the bottom lock 270 further includes a button spring 320 to reset the moveable support 308. In other words, the bracket 294 acts as a slip-joint and slides along a portion of the bottom lock pin height 286 between the top flange 288 and the bottom flange 290 when the depressible bottom lock button has not been depressed, and the bracket 294 lifts the bottom lock pin tip 292 only when the bottom lock pin tip 292 is in the bottom lock recess 400 (i.e., when the depressible bottom lock button 306 has been depressed). Optionally, the previously mentioned shield 272 is in the form of a cover plate 316 and a hinge 318, the cover plate 316 is configured to pivot along the hinge 318 from a closed position in which the cover plate 316 covers the depressible bottom lock button 306 to an open position in which the cover plate 316 does not cover the depressible bottom lock button 306.
The bottom lock 270 is believed to be novel independent of the pivoting rod 208. Thus, the bottom lock 270 having any of the features described herein may be used in doors, particularly doors that move in a sliding plane by a motor and break open, that don't utilize the pivoting rod 208.
Optionally, a top lock 280 is employed. Top locks are well-known in the art and any suitable top lock 280 may be employed, including for example, a cam 322 that rotates when depressing the panic bar 274 causes the top lock rod 282 to move downwardly (see
Both the height of the top lock rod 282 and bottom lock rod 276 may be adjustable to accommodate varying distances between the panic bar 274 location and the door bottom 224 and also varying distances between the panic bar 274 location and the door top. An exemplary mechanisms for rod adjustment known to those in the art utilize threaded rods—i.e., a male threaded rod that threads into a hollow female threaded rod to accommodate different panel heights. It is also known to use a slide mechanism with locking set screw. For the threaded rod, which is utilized in the illustrated
As mentioned, a C-shaped bracket 324 may be employed in such systems. The C-shaped bracket 324 may be attached to the inside of the door frame whose top horizontal member provides a mounting surface for the cam 322 and whose top and bottom members act only as a guide for the polygonal-shaped rod top end 303 or dually as support members for mounting other optional components such as the locking button mechanism 306 (similarly shown in
Re-setting of the cam 322 may be accomplished automatically by a resetting pin 305, shown in
The top lock rod 282 and bottom lock rod 276 may be attached to the gear 278 via pins 406, which allow for rotation of the bottom end 301 of the top lock rod 282 and the top end 302 of the bottom lock rod 276 around the pin 406 while the gear 278 is rotating and likewise moving the top lock rod 282 down and likewise moving the bottom rod 276 up (i.e., unlocking). This ability for the bottom end 301 of the top lock rod 282 and the top end 302 of the bottom lock rod 276 to rotate around the pins 406 allows for any misalignment between the centerline of the pin 406/engagement point in one end of the rod 301 and 302 and the centerline of the guide bracket 294 and 324 at the opposite end 303 and 304 of the rod 282 and 276.
The skilled artisan will be aware of the operation of such systems.
The top lock 280 and bottom lock 270 are generally present in both doors if the system 200 has two sliding doors.
The system 200 may also include an electric lock that also serves to prevent the door(s) 202 from sliding from the sliding closed position to the sliding open position. More particularly, a top lock rod 282 may only prevent the door 202 from breaking to the front open position. An electric lock inside the head (in communication with the motor) will prevent the door 202 from moving from the sliding closed position to the sliding open position. (The bottom lock 270 also prevents the door 202 from moving from the sliding closed position to the sliding open position but the depressible bottom lock button 306 is only depressed generally in the case of a hurricane or other emergency).
Optionally, the system 200 further comprises a door panel configured to remain fixed relative to the rectangular door system frame when the door 202 moves from the sliding closed position to the sliding open position, the door panel located to the side of the door 202 when the door 202 is in the sliding closed position, wherein the door 202 is configured to slide to the rear of the door panel when the door slides from the sliding closed position to the sliding open position, wherein the door panel is configured to move with the door 202 when the door 202 moves from the sliding plane to the door front open position.
Optionally, the system further comprises a track (not shown) located above the top panel and further wherein the system comprises a wheel (not shown) connected to the top panel and located in the track (not shown) and further wherein the wheel (not shown) is configured to move along the track (not shown) when the top panel and door slide from the sliding closed position to the sliding open position.
Optionally, the motor (not shown) is configured to move the wheel (not shown) along the track (not shown).
Having now described the invention in accordance with the requirements of the patent statutes, those skilled in the art will understand how to make changes and modifications to the disclosed embodiments to meet their specific requirements or conditions. Changes and modifications may be made without departing from the scope and spirit of the invention. In addition, the steps of any method described herein may be performed in any suitable order and steps may be performed simultaneously if needed.
Terms of degree such as “generally”, “substantially”, “about” and “approximately” as used herein mean a reasonable amount of deviation of the modified term such that the end result is not significantly changed. For example, these terms can be construed as including a deviation of at least ±5% of the modified term if this deviation would not negate the meaning of the word it modifies.
