Description
TITLE: SLIDING LOUVERED DOORS
FIELD OF THE INVENTION
The invention relates generally to sliding doors having movable louvers.
BACKGROUND OF THE INVENTION
Sliding louvered doors are an alternative to louvered bi-folding shutters.
Sliding louvered doors are often mounted in front of sliding glass doors. Sliding glass doors have an operational door and a stationary door. The operational door has a handle which varies with each manufacturer and presents a technical glitch to interior shutter door applications. Sliding louvered doors generally consist of a three piece frame (post and lintel construction method), supporting a pair of louvered sliding doors or a pair of bi-folding louvered shutters. In this type of construction the lintel must be supported by two vertical posts. The size (depth) of the vertical posts is determined by the handle protrusion. In order for the louvers to be opened or closed the shutter or louvered door must be positioned forward from the handle of the glass sliding doors a distance determined by the type of louver. These technicalities caused the standard 5', 6', 8' sliding patio shutter doors and frames to be customized due to complex details arising from the different patio door handles and their inconsistent installation patterns. In order to permit the doors to slide past each other, the two doors are mounted parallel to each other and the two doors are separated by a distance. The installation of plastic nylon guides on the floor provides directional guidance.
Another problem with the previous louvered sliding door designs is that the louvers had to be in the closed position to ensure that the doors can slide past each other without hitting or the doors had to be spaced far apart from each other to ensure the louvers do not hit the louvers of the other door. Also, previous applications of louvered shutters required a pair of bi-folding shutters due to louver length limits.
Present manufacturing methods of drilling standard 1 3/8" and 2" stiles in the center creates the limitations above. The combined limitations above and their complexity held back the popularity of previous louvered sliding door designs.
SUMMARY OF THE INVENTION
The present invention overcomes the disadvantages of the prior art by providing a louvered door arrangement which is compact and which allows the doors to slide past each other without hindrance. The invention includes a pair of sliding louvered doors each having a frame including a pair of stiles. Each stile has a front face and a rear face and a plurality of louvers mounted between the stiles, each of the louvers having opposite ends. An elongated head member is provided having two parallel support tracks, the louvered doors being suspended on the tracks such that the first louvered door is mounted parallel to and in front of the second louvered door, the two louvered doors being separated from each other by a distance such that the rear face of the stile of the first door faces the front face of the stile of the second door. The louvers of the first door are pivotally mounted to the stiles of the first door along a central axis of the stiles at a point of attachment on the end of the louvers, the point of attachment being selected such that a portion of the louvers extend beyond the front face of the stiles and the louvers do not extend substantially beyond the rear face of the stiles.
The louvers of the second door are also pivotally mounted to the stiles of the second door along a central axis of the stiles at a point of attachment on the end of the louvers, the point of attachment being selected such that a portion of the louvers extend beyond the rear face of the stiles and the louvers do not extend substantially beyond the front face of the stiles.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the preferred typical embodiment of the principles of the present invention.

DETAILED DESCRIPTION OF THE INVENTION
Referring firstly to figure 1, sliding louvered doors made in accordance with the present are shown generally as item 10 and consist of a pair of louvered sliding doors 18 (the front door) and 20 (the traffic door) mounted to a suspension frame 11. Frame 11 consists of an elongated head member 12 mounted which is anchored to the lintel of the existing patio door frame. Louvered doors 18 and 20 are preferably mounted directly to head member 12 by suspension rails (not shown) of the type generally used to hang sliding doors.
Referring now to figure 2, sliding louvered doors 18 and 20 each consist of a series of louvers mounted within a frame. Louvered door 18 has frame 22 consisting of top frame member or rail 24 and bottom frame member or rail 26 mounted between vertical frame members (stiles) 28 and 30. Stiles members 28 and 30 have inside walls 34 and 36 respectively. Louvers 32 are mounted to vertical stiles 28 and 30 between inside walls 34 and 36, respectively. The louvers are mounted in parallel spaced apart arrangement with the distance between the louvers being constant. Preferably, the louvers are either 2 inches or 3 inches appart. As better seen in figures 7 and 8, door 20 is mounted behind door 18 and the two doors are separated by a distance A
which is selected to be sufficient to permit the two doors to slide past each other without touching.
Referring now to figure 4, the louvers forming each door are pivotally attached to stiles forming the door's frame. Vertical stiles 28 and 30 of door 18 (the front door) are each provided with a row of louver mounting channels 50. Channels 50 are formed on inner wall 34 of stile 28 along central axis 51 of each stile. Preferably, channel 50 is positioned dead centre on inner wall 34 of stile 28. It will be appreciated that vertical stile 30 also has a corresponding louver mounting channel (not shown) which is oriented as channel 50. For door 20 (the traffic door), louvers 33 are mounted between vertical stiles 40 and 42 which are held together by top frame member 38 and lower frame element 44. Vertical stile 40 has a mounting channel 52 located parallel to vertical axis 47. Preferably, mounting channel 52 is positioned dead centre on front face 41 of the vertical stile 40. Likewise, vertical stile 42 also has a corresponding mounting channel (not shown) spaced several inches front face 43 of the support member and parallel to vertical axis 63.
As can best be seen in figure 5, louvers 32 and 33 are mounted within the stiles of doors 18 and 20 such that a portion of the louvers extend beyond the stiles. Each louver has inner and outer side edges. Louvers 32 each have inner side edge 74 and opposite outer side edge 75, while louvers 33 each have inner side edge 76 and opposite outer side edge 77. Each end of the louvers 32 and 33 are mounted to channels 50 and 52, respectively, at an attachment point located between the side edges of each louver. The attachment points 70 and 72 are positioned towards inner edges 74 and 76 of lovers 32 and 33, respectively. Attachment points 70 are selected such that a portion of louvers 32 extend beyond the front face 29 of stile 28.
Since attachment points 70 are positioned towards inner side 74 of each lover 32, the louvers do not extend past rear face 54 of the stiles forming front door 18. Likewise, since attachment points 72 are positioned towards inner side 76 of each lover 33, the louvers do not extend past front face 41 of stile 40 which is part of traffic door 20.
Portions of louvers 32 and 33 extend past front face 29 and rear face 55 of doors 18 and 20, respectively. Therefore, in this arrangement, rear face 54 of door 18 and front face 41 or door 20 may be brought very close together and the doors may still slide past each other without the louvers interfering with the movement of the doors. The asymmetric mounting of the louvers in the door frames permits the use of relatively wide louvers without causing the louvers to interfere with the operation of the doors.
Referring now to figure 6, mounting channels 50 and 52 comprise rack and pinion mounting assemblies. Each mounting channel consists of a pair of elongated racks 80 and 82 extending along the entire length of each mounting channel with a plurality of pinion gears 84 positioned between and engaging with each of the racks.
Racks 80 and 82 can move up and down in the direction indicated by arrows A
and B in response to the rotation of pinion gears 84. Each of the louvers 32 and 33 are mounted to pinions 84 at attachment points 70 and 72, respectively. Each of the louvers are mounted to channels 50 and 52 such that the louvers on each door are all parallel with one another louvers on the same door. Hence, pivoting one of the louvers causes each of the louvers on that door to pivot in the same way, causing the louvers to remain parallel with one another.
Referring now to figure 7, each lover mounting channel is identical; however, channel 52 shall be discussed in greater detail to illustrate the functioning of each of the channels. Mounting channel 52 consists of an elongated extrusion 88 which is positioned in a groove 86 cut in stile 40. Extrusion 88 holds racks 80 and 82 and mounts pinion gear 84. Pinion gear 84 has projecting shaft 90 which extends through an aperture 92 formed in extrusion 88. Shaft 90 is dimensioned to mount to louver 33 at attachment point 72. Preferably, shaft 90 is mounted in a tap hole formed in louver 33 at attachment point 72.
The operation of the present invention shall now be discussed with reference to figure 6. Louvers 33 and 32 are mounted to mounting channels 52 and 50, respectively, such that the louvers on each door are all parallel to each other. Doors 18 and 20 can be brought into close proximity to each other without worry of the louvers interfering with the movement of the doors. The pivotal position of all of the louvers on a door can be adjusted simultaneously by simply pivoting one louver. It has been discovered that the frictional forces created by pinions 84 and racks 82 and 80 is such that when the louvers are pivoted into position, the force of gravity is not sufficient to cause the louvers to move. Therefore, if the louvers are pivoted into a substantially horizontal position as shown in figure 5, the force of gravity is not sufficient to cause the louvers to move into the position shown in figure 6. In order to pivot the louvers into a more horizontal position, the user must physically force the louvers into position. In the event that the frictional forces generated by mounting channels 52 and 50 are not sufficient to keep the louvers in place, it is possible to add a weight 100 to one of the louvers of each door. If weight 100 is sufficiently large and if the weight is placed adjacent an outer edge of the louver, the weight will effectively counterbalance the louvers to keep them from pivoting by the force of gravity.
Referring now to figures 8 and 9, an alternate embodiment of the present invention is shown in which the mounting channels are positioned towards either the front or rear of the stiles with the louvers centrally mounted to the mounting channels.
For example, louvered doors 102 and 104 each have stiles 103 and 105, respectively.
Stile 103 has inner face 106 and outer face 108 and stile 105 has inner face 110 and outer face 112 with gap 109 separating the two doors. Each of the louvers 118 and 120 have opposite ends (not shown) which are coupled to the stiles of door 102 and 104, respectively. With reference to door 102, each louver 118 is couples to a pinion gear 123 which meshes with racks 126 and 128 of elongated channel 114. Pinion gear mounts to louvers 118 at attachment point 122 on the louver which is positioned at the centre of louver 118. Elongated mounting channel 114 is positioned on stile towards outer face 108 in order to position louvers 118 such that they do not extend beyond inner face 106. Likewise, with reference to door 104, each louver 120 is couples to a pinion gear 125 which meshes with racks 130 and 132 of elongated channel 116. Pinion gear 125 mounts to louvers 120 at attachment point 124 on the louver which is positioned at the centre of louver 120. Elongated mounting channel 116 is positioned on stile 105 towards outer face 112 in order to position louvers 120 such that they do not extend beyond inner face 110. Elongated mounting channels 114 and 116 are identical to the mounting channels in the previously disclosed embodiment, apart for their relative positioning on the stiles.
The orientation of louvers 118 and 120, and particular, the positioning of pinions 123 and 124 at the centre of the louvers, respectively, allows for the louvers to be balanced. As in the previous embodiment, physically moving one louver into an angled position, as shown in figure 9, causes all of the louvers on that door to move. Hence, the user can adjust all of the louvers simultaneously by just adjusting one louver.
A specific embodiment of the present invention has been disclosed; however, several variations of the disclosed embodiment could be envisioned as within the scope of this invention. It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.

DETAILED DESCRIPTION OF THE INVENTION
Referring firstly to figure 1, sliding louvered doors made in accordance with the present are shown generally as item 10 and consist of a pair of louvered sliding doors 18 (the front door) and 20 (the traffic door) mounted to a suspension frame 11. Frame 11 consists of an elongated head member 12 mounted which is anchored to the lintel of the existing patio door frame. Louvered doors 18 and 20 are preferably mounted directly to head member 12 by suspension rails (not shown) of the type generally used to hang sliding doors.
Referring now to figure 2, sliding louvered doors 18 and 20 each consist of a series of louvers mounted within a frame. Louvered door 18 has frame 22 consisting of top frame member or rail 24 and bottom frame member or rail 26 mounted between vertical frame members (stiles) 28 and 30. Stiles members 28 and 30 have inside walls 34 and 36 respectively. Louvers 32 are mounted to vertical stiles 28 and 30 between inside walls 34 and 36, respectively. The louvers are mounted in parallel spaced apart arrangement with the distance between the louvers being constant. Preferably, the louvers are either 2 inches or 3 inches appart. As better seen in figures 7 and 8, door 20 is mounted behind door 18 and the two doors are separated by a distance A
which is selected to be sufficient to permit the two doors to slide past each other without touching.
Referring now to figure 4, the louvers forming each door are pivotally attached to stiles forming the door's frame. Vertical stiles 28 and 30 of door 18 (the front door) are each provided with a row of louver mounting channels 50. Channels 50 are formed on inner wall 34 of stile 28 along central axis 51 of each stile. Preferably, channel 50 is positioned dead centre on inner wall 34 of stile 28. It will be appreciated that vertical stile 30 also has a corresponding louver mounting channel (not shown) which is oriented as channel 50. For door 20 (the traffic door), louvers 33 are mounted between vertical stiles 40 and 42 which are held together by top frame member 38 and lower frame element 44. Vertical stile 40 has a mounting channel 52 located parallel to vertical axis 47. Preferably, mounting channel 52 is positioned dead centre on front face 41 of the vertical stile 40. Likewise, vertical stile 42 also has a corresponding mounting channel (not shown) spaced several inches front face 43 of the support member and parallel to vertical axis 63.
As can best be seen in figure 5, louvers 32 and 33 are mounted within the stiles of doors 18 and 20 such that a portion of the louvers extend beyond the stiles. Each louver has inner and outer side edges. Louvers 32 each have inner side edge 74 and opposite outer side edge 75, while louvers 33 each have inner side edge 76 and opposite outer side edge 77. Each end of the louvers 32 and 33 are mounted to channels 50 and 52, respectively, at an attachment point located between the side edges of each louver. The attachment points 70 and 72 are positioned towards inner edges 74 and 76 of lovers 32 and 33, respectively. Attachment points 70 are selected such that a portion of louvers 32 extend beyond the front face 29 of stile 28.
Since attachment points 70 are positioned towards inner side 74 of each lover 32, the louvers do not extend past rear face 54 of the stiles forming front door 18. Likewise, since attachment points 72 are positioned towards inner side 76 of each lover 33, the louvers do not extend past front face 41 of stile 40 which is part of traffic door 20.
Portions of louvers 32 and 33 extend past front face 29 and rear face 55 of doors 18 and 20, respectively. Therefore, in this arrangement, rear face 54 of door 18 and front face 41 or door 20 may be brought very close together and the doors may still slide past each other without the louvers interfering with the movement of the doors. The asymmetric mounting of the louvers in the door frames permits the use of relatively wide louvers without causing the louvers to interfere with the operation of the doors.
Referring now to figure 6, mounting channels 50 and 52 comprise rack and pinion mounting assemblies. Each mounting channel consists of a pair of elongated racks 80 and 82 extending along the entire length of each mounting channel with a plurality of pinion gears 84 positioned between and engaging with each of the racks.
Racks 80 and 82 can move up and down in the direction indicated by arrows A
and B in response to the rotation of pinion gears 84. Each of the louvers 32 and 33 are mounted to pinions 84 at attachment points 70 and 72, respectively. Each of the louvers are mounted to channels 50 and 52 such that the louvers on each door are all parallel with one another louvers on the same door. Hence, pivoting one of the louvers causes each of the louvers on that door to pivot in the same way, causing the louvers to remain parallel with one another.
Referring now to figure 7, each lover mounting channel is identical; however, channel 52 shall be discussed in greater detail to illustrate the functioning of each of the channels. Mounting channel 52 consists of an elongated extrusion 88 which is positioned in a groove 86 cut in stile 40. Extrusion 88 holds racks 80 and 82 and mounts pinion gear 84. Pinion gear 84 has projecting shaft 90 which extends through an aperture 92 formed in extrusion 88. Shaft 90 is dimensioned to mount to louver 33 at attachment point 72. Preferably, shaft 90 is mounted in a tap hole formed in louver 33 at attachment point 72.
The operation of the present invention shall now be discussed with reference to figure 6. Louvers 33 and 32 are mounted to mounting channels 52 and 50, respectively, such that the louvers on each door are all parallel to each other. Doors 18 and 20 can be brought into close proximity to each other without worry of the louvers interfering with the movement of the doors. The pivotal position of all of the louvers on a door can be adjusted simultaneously by simply pivoting one louver. It has been discovered that the frictional forces created by pinions 84 and racks 82 and 80 is such that when the louvers are pivoted into position, the force of gravity is not sufficient to cause the louvers to move. Therefore, if the louvers are pivoted into a substantially horizontal position as shown in figure 5, the force of gravity is not sufficient to cause the louvers to move into the position shown in figure 6. In order to pivot the louvers into a more horizontal position, the user must physically force the louvers into position. In the event that the frictional forces generated by mounting channels 52 and 50 are not sufficient to keep the louvers in place, it is possible to add a weight 100 to one of the louvers of each door. If weight 100 is sufficiently large and if the weight is placed adjacent an outer edge of the louver, the weight will effectively counterbalance the louvers to keep them from pivoting by the force of gravity.
Referring now to figures 8 and 9, an alternate embodiment of the present invention is shown in which the mounting channels are positioned towards either the front or rear of the stiles with the louvers centrally mounted to the mounting channels.
For example, louvered doors 102 and 104 each have stiles 103 and 105, respectively.
Stile 103 has inner face 106 and outer face 108 and stile 105 has inner face 110 and outer face 112 with gap 109 separating the two doors. Each of the louvers 118 and 120 have opposite ends (not shown) which are coupled to the stiles of door 102 and 104, respectively. With reference to door 102, each louver 118 is couples to a pinion gear 123 which meshes with racks 126 and 128 of elongated channel 114. Pinion gear mounts to louvers 118 at attachment point 122 on the louver which is positioned at the centre of louver 118. Elongated mounting channel 114 is positioned on stile towards outer face 108 in order to position louvers 118 such that they do not extend beyond inner face 106. Likewise, with reference to door 104, each louver 120 is couples to a pinion gear 125 which meshes with racks 130 and 132 of elongated channel 116. Pinion gear 125 mounts to louvers 120 at attachment point 124 on the louver which is positioned at the centre of louver 120. Elongated mounting channel 116 is positioned on stile 105 towards outer face 112 in order to position louvers 120 such that they do not extend beyond inner face 110. Elongated mounting channels 114 and 116 are identical to the mounting channels in the previously disclosed embodiment, apart for their relative positioning on the stiles.
The orientation of louvers 118 and 120, and particular, the positioning of pinions 123 and 124 at the centre of the louvers, respectively, allows for the louvers to be balanced. As in the previous embodiment, physically moving one louver into an angled position, as shown in figure 9, causes all of the louvers on that door to move.
