BACKGROUND
The present disclosure generally relates to a wall panel system. More specifically, the present disclosure relates to both a sliding door and a pivot door that can be used with a wall panel system that includes laminated glass panels.
Panel-type wall systems are commonly used to divide space in an open-plan office environment. In a typical modular panel-type wall system, a number of wall panels are interconnected together in a configuration suitable for the intended use of the space. Each wall panel typically includes a structural flame to which a pair of tiles are mounted. The tiles may be broadly classified as either decorative tiles or functional tiles. Decorative tiles have an acoustic insulating material covered by an appropriate finishing material such as fabric, metal or wood and are designed to provide sound proofing and aesthetic appearance. Functional tiles generally have a tile frame that supports functional components, such as a tool rail, one or more hooks, an opening, a window, a shelf, a marker board, paper management components, etc.
The large number of panel-type wall systems currently available allow a business owner to divide an open space into a series of enclosed areas. Although panel-type wall systems are commonly available, the solid surfaces used in most panel systems create an enclosed area that may not have any exterior windows or any other types of glass areas open to allow light to enter into the enclosed area.
Presently, modular wall systems have been developed that include glass panels as the structural elements rather than just as windows within a typical panel system. The demountable wall systems that use tempered or laminated glass as the primary exposed surface increase the amount of light that reaches into the enclosed area defined by the wall panel. However, utilizing glass panels instead of solid, structural panels creates certain challenges since structural components of the panel systems are viewable through the glass panel members.
SUMMARY
The present disclosure generally relates to a wall panel system that includes a series of wall panels and a doorway defined by a pair of spaced vertical support posts and a horizontal header. The doorway can include either a sliding glass door or a pivoting glass door depending upon the user requirements.
In an embodiment in which the modular wall system includes a sliding door, the sliding door is supported by a sliding door track that is mounted to the horizontal header. The sliding door track is positioned adjacent to the horizontal header and extends along the entire length of the horizontal header and past one of the pair of spaced vertical posts. The sliding glass door is movable along the sliding door track to open and close the doorway.
The sliding glass door is attached to at least a pair of trolley assemblies that are each movable along the sliding door track. Each of the trolleys is connected to the sliding glass door by a mounting bracket. The mounting bracket securely supports the sliding glass door between the trolleys such that the sliding glass door moves along with the trolleys within the sliding door track.
The mounting brackets attached to the sliding glass door are adjustably connected to a trolley such that the distance between the upper end of the sliding glass door and the sliding door track can be adjusted. In this manner, the vertical height of the sliding glass door can be modified to compensate for adjustments in the panels of the wall panel system.
The sliding glass door further includes a lower trim assembly that is mounted to a lower end of the sliding glass door. The lower trim assembly is adjustable to modify the overall height of the sliding glass door. In this manner, the trim assembly can be slightly modified to compensate for adjustments made to the panels of the wall panel system.
The lower trim assembly includes a bottom clamp that is attached to the lower end of the sliding glass door. The position of the bottom clamp can be adjusted relative to the lower end of the sliding door. The adjustment made between the bottom clamp and the door are facilitated by a series of spaced attachment holes that are each sized to receive a connector that passes through a mounting hole formed in the sliding glass door. The bottom clamp can be adjusted such that the connector passes through a selected one of the spaced attachment holes.
In an alternate embodiment in which the modular wall system includes a pivoting glass door, the pivoting glass door is mounted and supported by a bottom pivot assembly and a top pivot assembly. The pivoting glass door is not supported on either one of the spaced vertical posts that defines the doorway and is instead supported by the bottom pivot assembly.
The bottom pivot assembly of the pivoting glass door includes a bottom clamp that is securely attached to the bottom end of the pivoting glass door. The position of the bottom clamp is adjustable relative to the bottom end of the pivoting glass door such that the overall vertical height of the pivoting glass door can be adjusted to compensate for adjustments made in the wall panels of the wall panel system.
The bottom clamp, when mounted to the bottom end of the pivoting glass door, receives a pivot pin that is supported on the floor of a building. The support provided by the pivot pin allows the pivoting glass door to pivot about a pivot access while a pivot pin supports the weight of the glass door.
The top pivot assembly is mounted to the top end of the pivoting glass door and defines a top end of the pivot access. The top pivot assembly includes a plunger that is received within the upper header to pivotally support the top end of the pivoting glass door. The plunger is biased into an extended position by a bias spring such that the plunger is received within a bushing formed within the upper header.
An upper end of the plunger that forms a portion of the top pivot assembly includes a sloped upper surface such that the sliding glass door can be moved into position with the plunger retracted. Once in position, the bias spring urges the plunger into engagement with the bushing formed as part of the horizontal header. The combination of the bottom pivot assembly and top pivot assembly define a pivot access and support the weight of the pivoting glass door.

DETAILED DESCRIPTION
FIG. 1 illustrates a demountable wall system (DWS) 11 constructed in accordance with the present disclosure. The wall system 11 shown in FIG. 1 includes multiple glass panels 13 that can be used with conventional solid wall panels or with each other to create multiple rooms 15.
In the embodiment shown in FIG. 1, the wall system 11 includes a both a sliding door 10 and a pivoting glass door 100 that can each be used to selectively expose a doorway to enter into one of the rooms 15. In the embodiment shown in FIG. 1, the adjacent wall panels 13 abut each other to create a panel joint 17. In the embodiment illustrated, the panel joint is a butt-glazed joint in which one of the side edges of the adjacent wall panels 13 includes a bulb seal that creates a seal between the pair of adjacent wall panels at the panel joint. In addition, one of the pair of wall panels 13 that define the corner also include a bulb seal to create the joint between the pair of walls positioned at a 90° angle relative to each other.
As illustrated in FIG. 1, the demountable wall system 11 includes a lower trim 19 and an upper trim 21 that enhance the overall aesthetic appearance of the demountable wall system 11. In the embodiment shown in FIG. 1, both the lower trim 19 and the upper trim 21 are continuous sections that extend across multiple glass wall panels 13. The upper and lower trim sections are installed after the construction of the demountable wall system and provide a visually appealing appearance for the wall system 11.
FIG. 1
a illustrates one embodiment of the sliding glass door 10 constructed in accordance with the present disclosure. The sliding glass door 10 is designed for use with the demountable wall system 11 shown in FIG. 1 that includes multiple glass wall panels 13 that can be used with conventional solid wall panels or alone to create multiple rooms. The demountable wall system 11 includes the sliding glass door 10 that is movable between the closed position shown in FIG. 1a and an open position to provide entry and exit into one of the rooms created by the demountable wall glass system. In addition to utilizing the sliding door 10 shown in FIG. 1, it is also contemplated that a pivoting glass door could be utilized with the modular wall system 11, as will be described in greater detail below.
As illustrated in FIG. 1a, the demountable wall system includes a pair of vertical posts 12 that are spaced from each other to define an open doorway 14 that can be open and closed through the sliding movement of the glass door 10. When the glass door 10 is in the closed position shown in FIG. 1, the outer edges 16 of the glass door 10 extend past inner edges 18 of the doorway 14.
The glass door 10 is movable along a sliding door track 20 that allows the sliding door 10 to move from the closed position to an open position in which the sliding door 10 is moved completely away from the doorway 14. In FIG. 1a, the door track 20 includes a broken section; however, the length of the door track 20 should be at least twice the width of the glass door 10.
FIG. 2 is a section view taken along line 2-2 of FIG. 1 and illustrates the attachment of the door track 20 to a door frame header 22. The door track 20 is an extruded component that is securely attached to the door frame header 22 through a series of connectors 24. The connectors 24 are spaced along the length of the header 22 such that the door track 20 can be securely supported on the header 22. As can be understood in FIG. 1, the door track 20 extends past the door frame header 22 and past the vertical post 12 that defines one side of the doorway. The header 22, in turn, is supported by the pair of vertical posts 12 and defines the top of the doorway. The extruded aluminum header 22 includes an insert 26 that receives a trim piece 28 to provide a finished appearance for the lower surface of the header 22.
As illustrated in FIG. 2, the sliding glass door 10 includes a glass panel 30 that is slidably supported relative to the stationary door track 20 by a pair of mounting brackets 32. Each of the mounting brackets 32 receives a pair of connectors 34 that extend through an outer face 36 of the mounting bracket 32. Each of the connectors 34 includes a threaded end 38 that is received by an internally threaded receiver 40. A resilient bushing 41 is positioned in each of the mounting holes formed in the glass panel 30 to protect the glass from the connectors 34 and receiver 40. The combination of the receiver 40 and the connector 34 connects the mounting bracket 32 to the glass panel 30 as illustrated.
The upper end 42 of the mounting bracket 32 includes a support plate 43 connected to the upper end by a pair of screws 41, as shown in FIG. 3a. As shown in FIG. 2, a connector 44 having a connecting post 46 extends upward through an access opening 48 formed in the door track 20 and is received within a trolley 50. The end 51 of the connecting post 46 is preferably threaded such that the distance between the trolley 50, and thus the door track 20, can be adjusted to adjust the effective height of the sliding glass door. The trolley 50 is movable within the door track 20.
The trolley 50 is more clearly shown in the side view of FIG. 3a. The trolley 50 and includes a support bar 49 that includes a pair of front rollers 53 and rear rollers 55. Both the front and rear rollers 53, 55 are entrapped within the sliding door track 20, as can be understood in FIG. 2. Each of the rollers 53, 55 travels along the length of the sliding door track 20 to permit smooth sliding movement of the sliding glass door. A top support bar 52 holds the trolley in the position indicted in FIGS. 2 and 3.
As illustrated in FIG. 2, an outer valence 54 is attached to the door track 20 to provide a visually desirable appearance to the outer surface of the door track 20.
Referring back to FIG. 1a, the bottom of the glass door 10 includes an adjustable lower trim assembly 56 that provides a visually desirable appearance for the bottom surface of the sliding glass door 10. FIG. 4 illustrates the details of the lower trim assembly 56. The lower trim assembly 56 includes an adjustable bottom clamp 58 that includes a pair of spaced vertical sidewalls 60 that are spaced to define an open receiving channel 62. The receiving channel 62 is sized to receive the width of the bottom end 64 of the glass panel 30, as best shown in FIG. 5.
Referring back to FIG. 4, the bottom end 64 of the glass panel 30 includes a pair of mounting holes 66. The mounting holes 66 are used to secure the bottom clamp 58 to the bottom end 64 of the glass panel 30. Specifically, a bushing 68 is positioned within the mounting hole 66 and a standoff 70 and screw 72 extend through one of the spaced attachment holes 74 and is received by a corresponding nut 76. The spaced attachment holes 74 allow the bottom clamp 58 to move upward or downward relative to the glass panel 30 such that the location of the bottom clamp 58 can be adjusted as needed. The adjustability between the bottom clamp and the glass panel 30 of the sliding door allows for slight adjustments to closely space the bottom of the sliding door to the floor.
As can be understood in FIGS. 4 and 5, a front cover 78 and a back cover 80 are received on the sidewalls 60 of the bottom clamp 58 to provide a visually desirable appearance for the lower trim assembly. The front and back covers 78, 80 can be formed of different types of material, such as a coated plastic or metal to provide the desired appearance of the lower end of the sliding door.
Referring back to FIG. 4, a pair of end caps 82 are attached to each end of the bottom clamp 58 to complete the visual appearance of the lower end of the sliding glass door.
A lower guide assembly 84 is positioned in alignment with one of the vertical support posts 12. The lower guide assembly 84 is mounted to the bottom end of the support post 12 by a pair of connectors 86. The lower guide assembly 84 includes a guide block 88 that is secured to an attachment plate 90 by a series of attachment screws 92 as shown in FIGS. 4 and 5. A pair of gaskets 94 are mounted to each side of the bottom end 64 of the glass door 30 to cushion the insertion of the bottom end 64 into the bottom clamp 58.
As can be understood in FIG. 5, the guide block 88 is received within a lower cavity 96 defined by the bottom clamp 58 to guide the sliding movement of the glass panel 30.
FIGS. 6-14 illustrate the details of a pivoting glass door 100 that can be mounted for pivoting movement between the pair of spaced vertical posts 12. The pivoting glass door 100 can be used in place of the sliding glass door 10 shown in the embodiments of FIGS. 1a-5 or can be used with a different room 15, as shown in FIG. 1. The pivoting glass door 100 is movable within the doorway defined by the spaced vertical posts 12 and the horizontal header 22. The door 100 includes a handle 102 that allows the door to pivotally open about a lower pivot assembly and an ripper pivot assembly, the details of which will be described in detail below.
FIG. 7 illustrates the lower pivot assembly 104 that is mounted to the bottom end of the vertical support posts 12. The lower pivot assembly 104 includes a pivot plate 106 that is positioned between the lowermost portion of the vertical support posts 12 and the ground. The pivot plate 106 receives a pivot bolt 108 that is received within an adjustable pivot receiver 110 of a bottom assembly 112.
Referring now to FIG. 14, the bottom assembly 112 is securely attached to the bottom edge 114 of the glass panel 116. The bottom assembly 112 includes an adjustable mounting block 118 that is securely attached to the bottom edge 114 of the door 116 through a pair of set screws 120. The mounting block 118 receives a pair of side shims 122 that are located on opposite sides of the glass panel 116. The side shims 122 are included to create a tighter fit between the glass panel 116 of the pivoting door and the vertical sidewalls 130 of the mounting block 118. As illustrated in FIG. 14, the bottom edge 124 of the glass panel 116 contacts a bottom shim 126 positioned within the open cavity 128 defined between the pair of spaced vertical sidewalls 130. In the embodiment shown, four separate bottom shims 126 are stacked on top of each other within the open cavity 128. The bottom shims 126 can have different thicknesses varying from inch to ⅛ inch such that different combinations of the bottom shims 126 can vary the location of the bottom edge 114. Since the pair of set screws 120 holds the mounting block 118 on the bottom edge 114, the position of the mounting block can be adjusted to adjust the overall height of the pivoting glass door. In the embodiment shown, the total adjustment from the lower shim 126 to each of the set screws 120 is approximately 1.75 inches. In this manner, the bottom assembly 112 can slightly adjust the overall height of the glass panel 116 that forms the pivoting door.
As illustrated in FIG. 14, trim sections 132 are each mounted to the mounting block 118 to provide a more visually desirable appearance for the bottom assembly 112. Each of the trim sections 132 is securely held in place as illustrated.
As illustrated in FIG. 14, a pair of bottom flanges 134 of the mounting block 118 defines an open receiving cavity 136. As illustrated in FIG. 7, the open receiving cavity 136 includes the bottom pivot block 138 that in turn receives the pivot member 110 and the pivot bolt 108. As shown in FIG. 15, a pair of set screws 139 extends through the bottom flange 134 and engages the bottom pivot block to hold the pivot block within the mounting block. The location of the bottom pivot block can be adjusted in or out to control the swing of the pivoting glass door.
FIG. 13 is a cross-section view illustrating the interaction between the top end 140 of the glass panel 116 that forms the swinging door and the header 22. In the embodiment shown in FIG. 13, the trim piece 28 mounted to the top header 22 includes a weather strip 142 that extend vertically below the trim piece 28 and engages a top surface 144 of the glass panel 116. The weather strip 142 provides a seal between the top header 22 and the glass panel 116 of the swinging door.
FIG. 8 is a bottom view showing one of the vertical posts 12. The vertical post 12 includes outer trim sections 146 that are received within clips 148.
FIG. 9 is a detail, partial section view illustrating the pivoting connection between the top of the pivoting glass door 100. The top end of the door includes a gasket 150 that is received in a top portion of the door. The gasket 150 provides support for a bias spring 152 which in turn acts upon a plunger 154. The plunger 154 extends into an upper pivot bushing 156 and has a sloped upper surface 158. The sloped upper surface 158 allows the top end of the pivoting glass door to be moved into position to initially depress the plunger 154 against the bias force created by the bias spring 152. Once the door is properly located, the bias spring 152 forces the sloped upper surface 158 into the upper pivot bushing 156. When in this position, the plunger 154, along with the lower pivot bolt 108 shown in FIG. 7, defines the pivot axis for the pivoting glass door.
As can be understood in the drawing figures, the weight of the pivoting glass door is supported on the floor rather than by hinges attached to the vertical support posts 12. The pivot axis defined by the lower pivot bolt 108 and the plunger 154 is spaced from the vertical support posts 12. Since one of the vertical support posts 12 do not need to support the entire weight of the pivoting glass door, the site of the vertical support posts 12 can reduced.
FIG. 10 is a section view taken along line 10-10 that illustrates the configuration of the vertical post and the inner edge 160 of the pivoting glass door 100. A pivot housing 166 is connected through the glass panel by a pair of mounting screws 168 that are each received within an attachment nut 170. The spring 152 is shown in its compressed condition within the pivot housing 166. Vertical post 12 includes a molding 162 having a resilient bulb seal 164.
FIG. 11 is a section view that shows the attachment of the pivot plate 106 through the use of one or more screws 172. The pivot plate 106 is located beneath the bottom edge of the vertical support post 12 and the ground.
FIG. 12 is a section view showing the attachment of a molding to an inner surface of the vertical support post 12. The molding 174 acts as a door stop and limits the movement of the pivoting glass door 100 to only one direction. The molding 174 includes a resilient bulb seal 176 that contacts the inner surface 178 of the pivoting glass door 100 when the glass door is in the closed position illustrated. The molding 174 includes a strike plate weldment 180 that is attached to the support post 12 through a screw 182. The strike plate weldment 180 is securely attached over the length of the vertical support post 12.
