CROSS-REFERENCE TO RELATED APPLICATION
This application claims priority to and the benefit of Provisional Application No. 61/802,016, filed on Mar. 15, 2013, the entire disclosure of which is incorporated herein by reference.


BACKGROUND
The present disclosure relates to partitions and partition systems for use in restrooms such as in public restrooms, and to methods of installing the same. Individual stalls, for example in public area restrooms, showers, changing stalls, or any variety of other such rooms requiring compartments or stalls, are typically found in schools, airports, movie theaters, stadiums, recreation parks, etc. These individual stalls are generally provided by subdividing walls in the form of separate vertical partitions installed after the room has been finished. In order to provide adequate stability and support, these partitions are attached to a vertical support member, often a stile or pilaster. When one end of a partition is mounted on a traditional wall, the other end of the partition generally terminates at the stile or pilaster. These partitions may be attached by brackets or other devices to a stile or pilaster in a plane perpendicular to the stile or pilaster. Stiles and pilasters may be used to frame doors in these stalls, wherein the door is mounted in line with and between two stiles or pilasters. The stiles or pilasters, themselves, generally may be anchored to the floor, hung from the ceiling, or both.
Typical partition system assembly requires attachment of the partition walls to vertical support members, including traditional walls, stiles, or pilasters, that are, themselves vertically connected to the floor and/or ceiling of the room where the partition system is being installed. Thus, where the walls, floor, and/or ceiling of the room are not perfectly level, as is often the case even within typical allowable construction tolerances, the alignment of the partition system is inevitably affected. As a result, the various members of the partition system, including the partition walls, vertical support members, and/or doors, may be misaligned. This misalignment may result in the formation of excessive openings or gaps providing a line of sight at the seams between adjacent partition panels or at the door hinges or seams, improper door closure or function at the door frames, unsightly aesthetics, and increases in the costs and timing of construction for installation of the partition panels as the panels may need to be specially made to non-standard dimensions to account for the room imperfections. Consequently, installation of such partition systems can be time consuming and expensive.
SUMMARY
A partition system is provided and includes a first stile, second stile spaced apart from the first stile, and a door rotatably coupled to the first stile such that the door is rotatable between the first and second stiles and can rotate between a closed position where a first end of the door is adjacent the first stile defining a first seam there-between and a second end of the door opposite the first end is adjacent the second stile defining a second seam there-between, and an open position where the second end of the door is swung away from the second stile. The partition system also includes a first member extending across the first seam when the door is in the closed position to block viewing through the seam. In an example embodiment, the first member is mounted to one of the door and the first stile. In a further example embodiment, the first member is received in a recess formed in the other of the door and the first stile when the door is in the closed position and is withdrawn from the recess when the door is in the open position. In one example embodiment, the recess is a channel. In a further example embodiment, the channel is formed on an end of one of the door and the first stile and the system further includes a channel shaped member complementary to the channel which is fitted into the channel such that the first member is received in the channel shaped member. In a further example embodiment, the first member is a first flange of an angle which first flange extends transversely from a second flange of the angle. In yet another example embodiment, the system also includes a second member extending across the second seam when the door is in the closed position. In another example embodiment, the second member is mounted to one of the door and the second stile.
In a further example embodiment a method of installing a partition system is provided. The method includes coupling a first stile bracket vertically to a first side wall, and coupling a first stile having a first end opposite a second end to the first stile bracket with the second end distal from the stile bracket such that the second end is vertically plumb. The method also includes coupling a first panel bracket vertically to a rear wall, the rear wall extending transversely from the first side wall, coupling a first side panel having a first end opposite a second end to the first panel bracket such that the second end is distal from the first panel bracket such that the first side panel second end is vertically plumb. The method further includes coupling a second stile to the first side panel such that the first side panel extends from the second stile to the first panel bracket, and rotatably coupling a first door including a first end opposite a second end to the first stile such that the door is rotatable between the first and second stiles between a closed position where the first end of the door is adjacent the first stile defining a first seam there-between and the second end of the door is adjacent the second stile defining a second seam there-between, and an open position where the second end of the door is swung away from the second stile. In another example embodiment, the method also includes coupling a second panel bracket vertically to a rear wall spaced apart from the first panel bracket, coupling a second side panel having a first end opposite a second end to the second panel bracket such that the second end of the second side panel is distal from the second panel bracket and such that the second side panel second end is vertically plumb, coupling a third stile to the second side panel such that the second side panel extends from the third stile to the second panel bracket, and rotatably coupling a second door including a first end opposite a second end to the second stile such that the second door is rotatable between the second and third stiles between a closed position where the first end of the second door is adjacent the second stile defining a third seam there-between and the second end of the second door is adjacent the third stile defining a fourth seam there-between, and an open position where the second end of the second door is swung away from the third stile. In yet another example embodiment, the method further includes coupling a head rail to the first and second side panels. In another example embodiment, coupling the first stile to the first stile bracket includes coupling the first stile to the first stile bracket with the first end of the first stile extending at an angle relative to the first side wall along a plane of the first stile extending through the entire first stile. In yet another example embodiment, coupling the first side panel to the first side panel bracket includes coupling the first side panel to the first side panel bracket with the first end of the first side panel extending at an angle relative to the rear wall along a plane of the first side panel extending through the entire first side panel. In one example embodiment, coupling the second side panel to the second side panel bracket includes coupling the second side panel to the second side panel bracket with the first end of the second side panel extending at an angle relative to the rear wall along a plane of the second side panel extending through the entire second side panel. In yet another example embodiment the method includes coupling one or more second panel brackets vertically to a rear wall spaced apart from the first panel bracket and coupling one or more second side panels, each of the one or more side panels having a first end opposite a second end, to the one or more second panel brackets, such that each of the one or more side panels is coupled to a corresponding second panel bracket of the one or more second panel brackets, such that the second end of each of the one or more second side panels is distal from its corresponding second panel bracket and such that the each of the one or more second side panel second ends is vertically plumb. The embodiment may further include coupling one or more third stiles to the one or more second side panels such that the one or more second side panels extend from their corresponding third stile to their corresponding second panel bracket, and rotatably coupling at least one or more second doors including a first end opposite a second end to the one or more second stiles, wherein each of the one or more second doors is rotatable between its corresponding second and third stiles between a closed position where the first end of each of the one or more second door is adjacent its corresponding second stile defining a third seam there-between and the second end of each of the one or more second doors is adjacent its corresponding third stile defining a fourth seam there-between, and an open position where the second end of each of the one or more second doors is swung away from its corresponding third stile. In yet a further example embodiment, the method also includes coupling a second stile bracket to a second side wall spaced apart from the first side wall, wherein the rear wall extends between the first and second side walls, coupling a fourth stile having a first end opposite a second end to the second stile bracket with the first end of the fourth stile distal from the stile bracket and wherein the first end is vertically plumb.

DETAILED DESCRIPTION
The present disclosure relates to partitions and partition systems for use in restrooms such as public restrooms, to partitions and partition systems having line-of-sight blocking in the seams or gaps between partition panels and to methods of installing the same.
FIG. 1 shows a perspective view of a partition system 100 according to an embodiment of the present disclosure installed in a room 104. The partition system 100 includes a plurality of stalls 102, where each stall 102 has a door 16, at least one side panel 18, separating adjacent stalls. Adjacent doors are separated from each other by a stile. The partition system 100 has one first end stile 10 connected to a first side wall 60 of the room, and one second end stile 12 connected to a second side wall 62 of the room. In other embodiments where the partition system 100 does not extend to a second side wall 62, the partition system may be connected to only the first side wall 60 at the first end stile 10, and may be connected to a side panel 18 at the second end stile 12, as shown in FIGS. 10a and 10b. The partition system 100 also includes at least one interior stile 14 in line with the first end stile 10 and the second end stile 12. The stiles 10, 12, 14 are lined up and plumbed along a vertical plane. Each stile 10, 12, 14 is spaced apart from its adjacent stile 10, 12, 14 to create the opening where each stall door 16 is located.
With reference now to FIGS. 1, 2a and 2b, in embodiments of the present disclosure, the first end stile 10 is connected to the first side wall 60 via a first stile bracket 30. In some embodiments, the first stile bracket 30 is an angle or a channel. The first stile bracket 30 is configured to be attached abutting the first side wall 60. Often, the walls, floors, and ceilings of a room will not be perfectly plumb or level as a result of various factors, for example construction related factors. For example the surface 61 of the wall 60 is offset by an angle 63 from a vertical plane 65. In embodiments of the present disclosure, the first stile bracket 30 is attached to the first side wall 60 such that the first stile bracket 30 extends vertically along the first side wall 60. In some embodiments, a first portion proximate first edge 110 of the first end stile 10 is attached to the first stile bracket 30 and adjusted such that a second edge 112 of the first end stile 10, opposite the first edge 110, is vertically plumb relative to a reference point. For example, the stile is attached, as for example by fasteners, to the first stile bracket at an angle (e.g., when the wall surface 61 extends at angle, such as an angle 63, such that it is not perfectly vertical) such that the second edge 112 is vertically plumb, i.e., it is parallel to vertical plane 65. When attached in this manner, the first end stile 10 second edge (which defines the opening for receiving the door) is perfectly plumb, even where the first side wall 60 and the first stile bracket 30 are not plumb relative to the vertical plane. In an example embodiment, the first stile bracket 30 should have sufficient width 67 along its entire length to allow the stile to be rotated with its first edge 110 completely overlapped by the width while the second edge is vertically plumb. In some embodiments where the first stile bracket 30 is an angle, the first end stile 10 is attached to the first stile bracket 30 at a portion on a rear surface 114 of the first end stile 10 proximate its first edge 110. In some embodiments, the first stile bracket 30 extends the entire length of the first end stile 10. In other embodiments, the first stile bracket 30 extends only along a portion of the length of the first end stile 10. In some embodiments, the first end stile 10 is fully structurally supported by the first stile bracket 30, such that the first end stile 10 is suspended, meaning it is not connected to the floor or ceiling of the room 104.
With continued reference to FIGS. 2, 6a and 6b in one embodiment, the first end stile 10 includes at least a portion of a hinge member 26 along or proximate a second edge 112 of the first end stile 10, defining a portion of a first seam 20. In one embodiment, the hinge member 26 includes two complementary hinge elements 26a, 26b. At first, hinge element 26a in an example embodiment includes at least two knuckles 26c. A second hinge element 26b including at least one knuckle 26d. Knuckle 26d is positioned between knuckles 26c and a hinge pin (not shown) penetrates the knuckles 26c, 26d for rotatably coupling the hinge elements 26a, 26b together, as for example shown in FIG. 6b. In other embodiments, the second hinge element 26b is attached at or proximate the second edge 112 and the first hinge element 26a is attached to the door 16. A first seam 20 is a defined by a gap between a door and its adjacent stile, as for example shown in FIG. 6b. 
With reference now to FIGS. 1 and 3a, in embodiments of the present disclosure, each side panel 18 is connected to the rear wall 64 via a panel bracket 32. In some embodiments, the panel bracket 32 is an angle or a channel. The panel bracket 32 is configured to be attached abutting the rear wall 64. It may be fastened or otherwise adhered to the rear wall 64. In embodiments of the present disclosure, the panel bracket 32 is attached to the rear wall 64 such that the panel bracket 32 extends vertically along the rear wall 64. In some embodiments, a first end 184 of the side panel 18 is coupled to the panel bracket 32 and adjusted such that a second end 186 of the side panel 18, opposite the first end 184, is vertically plumb relative to a reference point. The first end 184 of the side panel 18 is coupled to the panel bracket by fastening or otherwise adhering a portion of the side panel proximate the first end 184 to the panel bracket and/or by fastening or otherwise adhering the first end 184 to the panel bracket. When attached in this manner, each side panel 18 is perfectly plumb (i.e., each side panel second end 186 opposite the first end 184 is perfectly plumb), even where the rear wall 64 and the panel bracket 32 are not, relative to the vertical plane. In such case, the first end is at one angle relative to the rear wall and the panel bracket. As with the stile bracket, in an example embodiment, the panel bracket should have sufficient width along its entire length to overlap the first end 184 of the side panel, while the side panel second end is vertically plumb. In some embodiments where the panel bracket 32 is a channel, the side panel 18 is attached to the panel bracket 32 at a first end 184 of the side panel 18, as for example shown in FIG. 3a. In some embodiments, the panel bracket 32 extends the entire length of the side panel 18. In other embodiments, the panel bracket 32 extends only along a portion of the length of the side panel 18. In some embodiments, each side panel 18 is fully structurally supported by the panel bracket 32, such that each side panel 32 is suspended, meaning it is not connected to the floor or ceiling of the room 104. Each panel may be fastened with fasteners or otherwise adhered to its corresponding panel bracket.
With continued reference to FIG. 1, in one embodiment, the partition system 100 includes floor supports 42 at a bottom surface 190 (as shown in FIG. 7b) of each side panel 18, connecting the side panel 18 to the flooring surface of the room 104. In one embodiment, the floor support 42 has an adjustable height optimal for leveling the supported connecting side panel 18 to a desired height. In one embodiment, the floor supports 42 can be mounted to the flooring surface, for example through a screw system, silicone, or other adhesive or mounting mechanisms. The floor supports 42 can be any suitable material as will be appreciated by those skilled in the art. In one embodiment, the floor supports 42 can be aluminum, aluminum with nylon, stainless steel, or any combination thereof. In one embodiment the floor supports 42 are self-leveling floor mounted pedestals with grouted set pins.
With reference now to FIGS. 4a, 4b, 5a, and 5b, optionally in some embodiments, the partition system 100 may include a head rail 50. The head rail 50 is configured to provide additional stability and structural support, for example in a lateral direction, for the partition system 100, and an example embodiments at the side panels 18. Additionally, the head rail 50 may be used to support additional panel members above the doors 16, stiles 10, 12, 14, or side panels 18. In some embodiments, the head rail 50 is attached directly to the side panels 18, and is independent from the doors 16 or the stiles 10, 12, 14. In one embodiment, the head rail 50 is connected to at least two side panels 18 via a rail connection member 52, as shown in FIGS. 5a and 5b. The head rail 50 may be connected to any number of adjacent side panels 18 or other members, as shown in FIGS. 4a and 4b. In one embodiment, the rail connection member 52 is first mounted to the top surface 188 and/or side surfaces proximate the top surface of each corresponding side panel 18. In some embodiments, as shown in FIG. 4b, the rail connection member 52 includes a horizontal plate 52a that sits on or over the top surface 188 of the side panel 18, an vertical plate such as an angled plate 52b (i.e., a plate having an edge such as edge 52d extending at an angle from the horizontal plate) protruding from the horizontal plate 52a such that its edge 52d is at an angle between 0 and 90 degrees away from the top surface 188 of the side panel 18, and a channel (or angle) 52c connected to the angled plate 52b adapted to receive the head rail 50. In the example embodiment shown in FIG. 4b, the connection member includes two spaced apart angled plates 52b. In other example embodiments, the rail connection member is just a channel (or angle) 52c that is coupled to the upper surface 188 of the side panel 18. In some example embodiment, a channel leg 52e (FIG. 4b) of the channel 52c may be received in a slot 52d defined in the head rail, as for example shown in FIG. 5b. 
In some embodiments, the rail connection member 52 is inset from the front surface 116, 126 of each stile and corresponding door of the partition system 100 such that the head rail 50 is set back a specified distance from the front surface of the partition system 100, as shown in FIG. 5b. In other embodiments, the head rail 50 is flush with the front surface 116, 126 of the partition system 100, as shown in FIG. 5a (the front surfaces of the stiles are shown in FIGS. 8 and 9a). In one embodiment, the rail connection member 52 is attached to the top surface 188 and/or side surface of each side panel 18 at a specified distance from the second end 18b or the first end 184 of the side panel 18. The head rail 50 can be any suitable material as will be appreciated by those skilled in the art. The head rail can be cut to an appropriate length at the installation site. In one embodiment, the head rail 50 can be solid aluminum. In one embodiment, the head rail 50 in conjunction with the connection of the first end stile 10 to the first side wall 60, and the connection of each side panel 18 to the back wall 64, provides sufficient structural support for the partition system 100 such that partition system does not require floor supports 42, and the partition system 100 is fully suspended from the first side wall 60, the rear wall 64, and/or the second side wall 62.
In other embodiments where the head rail is desired to be to be flush with the second (or front end surface) 186 or with a side surface 189 of its side panel 18, a rail connection member may be used, as for example rail connection member 53 shown in FIGS. 11a, 11b and 11c, over which is fitted the head rail 50. In an example embodiment, the rail connection member 53 is a channel member which is fastened to the top surface 188 of the side panel. The head rail also defines a channel. In one example, the head rail defines an “H” in cross-section, as for example disclosed in FIGS. 11a and 11b which defines two abutting channels 51a and 51b, or may it may be just a single channel 51a, as for example shown in FIG. 11c. The head rail channel 51a fits over the connection member 53 such that a surface 54 of the head rail is flush with a desired surface, as for example side surface 189 (FIGS. 11a and 11b) or end surface 186, as for example shown in FIG. 11c of the side panel 18. In an example embodiment, the head rail channel 51a fits snuggly over the connection member 53 such that lateral movement of the head rail relative to the connection member is minimized or alleviated. In an example embodiment, the connection member is fastened to the upper surface 188 of the side panel 18, as for example by using two fasteners 55a, as for example shown in FIG. 11b. A fastener 55b is then fastened through a lateral surface 57 of the head rail. The lateral surface 57 is the surface that interconnects the two legs that define the channel 51a. In other embodiments, a single fastener 55b is used that penetrates and/or is fastened to the lateral surface 57 of the head rail, penetrates and/or is fastened to the connecting member 53, and fastens into the side panel 18, as for example shown in FIG. 11a. The use of a head rail that is flush with a surface, as for example the side surface 189 of the panel 18, and which hides the connecting member 53 is desirable, especially when the partition system is installed against only one side wall and a panel 18 is used to define the end of the partition system. In such example embodiments, the head rail has to go over and along the upper surface 188 of the side panel 18 defining the end of the partition system. On such side panel defining the end of the partition, the head rail cannot be offset so that it would not be visible from outside of the partition system. In such case, this example embodiment provides for a cleaner connection between the head rail and the panel 18 by hiding the connecting member inside the head rail. In such an embodiment, the head rail forms a 90° angle such that a first portion of the rail runs across the side panels and a second portion perpendicular to the first portion running along the side panel defining the end of the partition. In an example embodiment, the two portions have ends that are mitered at 45° and the mitered ends are connected to each other using well known methods to form the head rail. In embodiments, the head rail may also be connected to both side walls or to a side wall and a rear wall when the partition is installed in a location including only one side wall.
With reference now to FIG. 3a, in some embodiments, each side panel 18 includes panel connection member 34 at a second end 186, opposite the first end 184, of the side panel 18. In some embodiments, the panel connection member 34 is configured to be attached to and support an interior stile 14 or a second end stile 12 attached in a plane substantially perpendicular to the side panel 18, as shown in FIG. 9b. In one embodiment, the panel connection member 34 is a plate 34a having a relatively flat surface 34b on one face, and a channel 34c extending opposite the face, such that the second end 186 of the side panel 18 is sandwiched in the channel portion of the panel connection member 34, and the face having a relatively flat surface is connected to a stile 12, 14, as for example shown FIG. 3b. In other example embodiments, the connection member 54 is just a channel 34c, as shown in FIG. 3c or a flat plate is shown in FIG. 3d. In embodiments of the present disclosure, the panel connection member 34 runs along the entire length of the side panel 18. In one embodiment, the panel connection member 34 runs along only a portion of the length of the side panel 18. The connection member 34 may be fastened or otherwise adhered to the side panel 18 used the stile 12, 14.
In some embodiments of the present disclosure where the room 104 in which the partition system 100 is installed only has a first side wall 60 to which the partition system 100 is attached, the partition system 100 may include an additional side panel 18 in lieu of a second side wall 62. In these embodiments, the second end stile 12 attaches to a side panel 18 at the panel connection member 34. The panel connection member 34 in these embodiments may have a portion attached along a portion of the length of the second end 186 of the side panel 18, and a portion attached along a portion of the length of the second end stile 12 on a rear surface 124 at a second edge 122 of the second end stile 12. In other embodiments, the side panel 18 connected to the second end stile 12 may not include a panel connection member 34, and the second end stile 12 may be connected to the side panel 18 via a second stile bracket 40 (as shown in FIG. 10b). In some embodiments, the second stile bracket 40 is an angle. In these embodiments, the second stile bracket 40 may be attached to the side panel 18 proximate the second end 186 on an interior face of the side panel 18, along a portion of the length of the side panel 18, and along the second end stile 12 proximate the second end stile second edge 122.
With reference now to FIGS. 1, 6a, and 6b, each stall door 16 of the partition system 100 is rotatably coupled or connected to a stile 10, 12, 14, at one edge 160, 162 of the door 16, such that a first seam 20 is created where the stile 10, 14, connects to the door 16 at the rotatable connection. The door 16 is rotatably connected to the stile 10, 14 through the hinge member(s) 26. In embodiments where the hinge member 26 includes two complementary hinge elements 26a, 26b, the hinge member may be a spring-loaded, force-adjustable hinge having two complementary hinge elements 26a, 26b. In one embodiment, the hinge member 26 includes at least one recessed hinge. In one embodiment, the hinge member 26 includes at least one surface mount barrel hinge. Other hinge members well known in the art may be used.
