Description




BACKGROUND AND SUMMARY OF THE INVENTION




The present invention relates to a space dividing or partitioning system, such as for use in an office environment. More specifically, the invention relates to such a system that can be easily assembled and disassembled providing numerous space dividing configurations.




A wide variety of office space partitioning or dividing systems are known. Many such systems include individual pre-assembled wall panels that are rigidly interconnected to each other to form a sectioned wall assembly. A pre-assembled panel typically includes a factory assembled panel frame that receives a decorative tile. The decorative tile typically includes a hook member extending from its back face surface that is received in a notched opening in the panel frame. The hook members on each of the tiles allow the tile to be hung from the panel frame. In such a system, it is common to provide a power distribution system toward the lower end of each wall panel, incorporating power receptacles at spaced locations. It is also known to provide power and/or communication distribution in each panel substantially at desk height.




While this type of wall construction functions well and has met with success, it involves certain drawbacks. For example, since each of the decorative tiles includes a hook member extending from its back face surface, care is required in storage and transportation of the individual tiles so as not to bend the hook members on the decorative tile. Further, the space occupied by the hook members prevents the tiles from being efficiently stacked for shipment or storage, and the tiles must be protected to prevent damage which maybe caused by the hook members when the tiles are stacked. Additionally, since the panel frames are typically pre-constructed, if the office owner wishes to reconfigure the panel system, additional panels having the desired configuration must either be retrieved from storage or ordered from the panel manufacturer.




Field-installed panel systems have been developed to overcome certain limitations of wall systems based on prefabricated panel frames. These systems generally include posts and horizontal support members which are selectively engageable with the posts. The posts and horizontal support members are assembled together to construct the skeleton of a wall, and tiles are engaged with the posts to form a wall system. In known systems of this type, however, a module defined by a pair of posts and horizontal support members interconnected therebetween cannot be reconfigured, such as by changing the location of the horizontal support members, without disassembling the entire module. In these systems, if the office owner wishes to add additional horizontal support members to the panel frame or alter the location of existing horizontal support members, the panel frame must be disassembled and the vertical uprights separated to permit the positioning of the horizontal support member therebetween.




It is an object of the present invention to provide a space dividing or partitioning system incorporating field-assembled panel frames. It is a further object of the invention to provide such a system that includes horizontal support members attached between spaced vertical posts, where the horizontal support members can be attached to the vertical posts without separation of the vertical posts. Another object of the invention is to provide such a system that can be quickly and easily reconfigured with a minimal amount of labor. Yet another object of the invention is to provide such a system that can be constructed from a minimal number of core components, such that storage space for the components when not in use is minimized. A still further object of the invention is to provide such a system in which the decorative tiles are hung to each panel frame by independent tile retaining hooks not permanently attached to either the tile or the panel frame. Yet another object of the invention is to provide a tile frame for each of the decorative tiles that can be assembled from individual tile frame members welded at overlapping locations. A still further object of the invention is to provide such a system including horizontal support members that can be attached between the vertical posts in either an upright or an inverted manner. Yet another object of the invention is to provide a novel method of mounting power and data communication wires beneath the individual panels. Yet another object of the invention is to provide a space dividing or partitioning system that can be assembled and disassembled into numerous configurations, including half wall, full wall, and “off-module” mounted walls. A further object of the invention is to provide an overhead storage member that can be slidably mounted within a channel formed in each of the horizontal support members, such that the overhead storage member can be mounted “off-module” and slid between adjacent panel frames.




Generally, the invention contemplates a space dividing or partitioning system for use in a building having a floor and a ceiling. The space dividing system of the invention includes a series of interconnected wall modules or panels, each formed from a field-assembled panel frame and one or more decorative tiles hung on the panel frame. Each panel frame is formed from a pair of vertical posts and at least one horizontal support member positioned between the vertical posts. The vertical posts are configured such that each post is common to adjacent wall modules or panels. Each vertical post may be formed from one or more post sections interconnected by a splice section. The post sections may be either a half post section or a full post section.




Each of the half post sections and full post sections includes a series of vertically aligned receptacles extending from their front and rear face surfaces. The receptacles are spaced and sized to receive attachment members contained on each end of the horizontal support member.




Each horizontal support member defines opposed first and second ends, and is formed from a bottom wall and a pair of opposed sidewalls. The bottom wall of each horizontal support member includes a pair of cut-outs extending from both the first end and the second end of the horizontal support member. The cut-outs allow the horizontal support member to be mounted between a pair of vertical posts that are spaced apart a distance less than the length of the horizontal support member without first separating the vertical posts.




In accordance with another aspect of the invention, a tile retaining hook is inserted into a hook opening formed in the panel frame. The tile retaining hook extends from the panel frame and is received within a hook channel formed in the decorative tile to be hung on the panel frame. The tile includes a pair of hook channels formed on each corner that extend at a 90° angle with respect to each other. The tile can thus be mounted to the panel frame either vertically or horizontally, depending upon the user's requirements.




In accordance with yet another aspect of the invention, a horizontal support member is inverted and mounted near the bottom end of the panel frame. The inverted horizontal support member provides the required support for an electric wireway extending between adjacent joined panels.




In accordance with yet another aspect of the invention, each horizontal support member is configured to provide access to openings contained on the vertical post when the horizontal support member is mounted between a pair of vertical posts. An opening formed in the horizontal support member is alignable with an opening formed on the vertical post when the horizontal support member is mounted to the vertical post. A tile retaining hook extends through the aligned openings and functions to interlock an end of the horizontal support member with the vertical post. Additionally, proper alignment of the opening in the horizontal support member and the opening in the vertical post ensures proper construction of the panel frame.




In accordance with another aspect of the invention, a base cover is mounted below the inverted lower horizontal support member to provide a cover for the wireways mounted to the series of interconnected panels. Each base cover includes a lower wall and a pair of base sides that engage the lower horizontal support member. The base cover can be opened to provide access to the wireway.




In accordance with yet another aspect of the invention, the electric wireway includes a series of rigid wireways joined by electric wire connectors. The rigid wireways are each supported below the inverted lower horizontal support member by electrical hanging brackets that engage the rigid wireway and the inverted lower support member.




In accordance with a further aspect of the invention, the tiles are constructed from a series of frame members each joined by a corner connector. The corner connector is received within a channel formed in each frame member. Each frame member includes an attachment flange extending from the channel. When the tile frame is assembled, a raised portion of each attachment flange overlaps a portion of the adjacent attachment flange, such that the adjacent attachment flanges can be spot welded to securely form the tile frame.




In accordance with yet another aspect of the invention, the space dividing or partitioning system of the invention can be field-assembled from a minimal number of separate components. In particular, each of the vertical posts is constructed from joined vertical post sections. The height of each vertical post is determined by the number of vertical post sections selected. Each of the vertical post sections are joined by a splice section received within the hollow interior of each post section. Once the vertical posts have been assembled, the horizontal support members are attached at the desired locations along each of the vertical posts to form a panel frame. Since each vertical post includes a series of regularly spaced receptacles extending along its length, the horizontal support members can be attached between a pair of the vertical posts at user-selected locations.




In accordance with a further aspect of the invention, an overhead storage member is provided that can be mounted between a pair of adjacent panels. The overhead storage member includes a mounting arrangement that is slidably received in a channel formed in a sidewall of the horizontal support member. The mounting arrangement includes a support flange that extends from a back wall of the overhead storage member and is received in the channel. The support flange can slide between the horizontal support members contained on adjacent panel frames such that the overhead storage member can be mounted in any location relative to the panels, including “off-module” mounting.




In accordance with a further aspect of the invention, an intermediate horizontal support member can be inserted into an assembled panel frame without disassembling the panel frame. Specifically, the horizontal support member can be inserted into the panel frame without first separating the vertical posts.




The various aspects of the invention can be employed separately or in sub-combinations as desired. In a particularly preferred form, however, all of the various aspects of the invention are incorporated in a space dividing or partitioning system to provide such a system having significant advantages in manufacture, installation and reconfiguration.




Various other features, objects and advantages of the invention will be made apparent from the following description taken together with the drawings.

DETAILED DESCRIPTION OF THE INVENTION





FIG. 1

illustrates a space dividing or partitioning system


60


constructed in accordance with the present invention. Space dividing system


60


is adapted for use in a building having an open space between a floor


62


and a ceiling, and is operable to divide the open space into smaller areas. In particular, space dividing system


60


is adapted for use in a work place environment to divide the open space into individual work areas, meeting areas, reception areas or the like. Generally, space dividing system


60


includes a series of interconnected panels


64


that can be joined in numerous configurations to define the individual areas. Each of the panels


64


generally includes a field-assembled panel frame


66


and one or more decorative tiles


68


that are supported on the panel frame


66


. The tiles


68


define the walls of the individual area and often include a decorative pattern.





FIGS. 2-13

illustrate the construction of the panel frames


66


. Referring first to

FIG. 2

, each panel frame


66


generally includes a pair of vertical posts


70


joined by at least one horizontal support member


72


. In the embodiment shown, the panel frame


66


includes both an upper and a lower horizontal support member


72


. The vertical posts


70


are spaced apart by the length of each horizontal support member


72


, and the connection between the posts


70


and the horizontal support members


72


provides the required rigidity for the panel frame


66


.




In order to provide a space dividing system


60


that can be assembled and disassembled to create individual areas having a variety of configurations, each of the vertical posts


70


shown in

FIG. 2

may be constructed from a pair of individual post sections joined together by a splice section. In the panel frame


66


shown in

FIG. 2

, the right vertical post


70


is constructed from two full post sections


74


that are joined together by a splice section


76


, while the left vertical post


70


is formed from a pair of half post sections


78


joined by a splice section


80


. Alternatively, each vertical post


70


may be continuous and formed without splices.




As shown in

FIG. 9

, the splice section


76


is received within an open interior


82


defined by the outer walls of the full post section


74


. Full post section


74


is formed from two identical mating outer wall sections


84


that define the generally rectangular open interior


82


. The pair of identical outer wall sections


84


are joined along a pair of longitudinal seams


86


by a series of spaced welds


88


. In the preferred embodiment of the invention, each of the outer wall sections


84


forming the full post section


74


is formed from sixteen gauge cold rolled steel to provide the required strength and rigidity for the panel frame


66


.




As can be seen in

FIGS. 9 and 10

, the splice section


76


includes a series of web sections


90


that extend outward and create an interference fit with inner surfaces


92


of the full post section


74


. Each web section


90


includes a tapered portion


94


that allows the splice section


76


to be inserted into the open interior


82


of the full post section


74


. As shown in

FIGS. 2 and 10

, the splice section


76


is positioned between the upper and lower full post sections


74


such that the splice section


76


securely connects the upper and lower full post sections


74


to generally define the complete vertical post


70


to be utilized in the panel frame


66


. Constructing each vertical post


70


from two separate full post sections


74


allows the panel frame


66


to be constructed having either the full height as shown, or a reduced height if only one full post section


74


is used.




Referring now to

FIG. 8

, the half post section


78


is constructed in a similar manner to the full post section


74


previously discussed. However, the width of the half post section


78


is approximately half the width of the full post section


74


. In construction of the panel frame


66


, the full post sections


74


are used to form the vertical post


70


between adjacent panels extending in the same direction, while the half post sections


78


are utilized to form a vertical post


70


at end of run locations, such as where adjacent panel frames


66


extend at a 90° angle with respect to each other, as shown in FIG.


2


. The half post section


78


is constructed from a pair of outer wall sections


96


that are joined along a longitudinal seam


98


by a series of welds


100


. Splice section


80


includes a series of web sections


102


that extend outward and create an interference fit with inner surfaces


104


of the half post section


78


. Tapered portions


106


of each web section


102


allow the splice section


80


to be inserted between the upper and lower half post sections


78


, such that the left complete vertical post


70


can be constructed as shown in FIG.


2


.




Referring now to

FIGS. 3 and 7

, the full post section


74


and the half post section


78


will now be described, with the understanding that like features on each will be identified by corresponding reference numerals to facilitate understanding. However, as the figures clearly illustrate, the half post section


78


is approximately half the width of the full post section


74


. Both the full post section


74


and the half post section


78


include a pair of face surfaces


106


. Since both the full post section


74


and the half post section


78


are constructed from identical outer wall sections


84


and


96


, respectively, both face surfaces


106


are identical. Each face surface


106


includes a series of formed-out receptacles


108


. The receptacles


108


each include a curved retaining flange


110


that extends outward from the otherwise flat face surface


106


, as can best be seen in FIG.


4


. The retaining flange


110


includes a curved edge


112


spaced a predetermined distance from the face surface


106


, for reasons that will be discussed in detail below. The receptacles


108


each extend outwardly of an opening


114


which communicates with the open interior


82


of the full post section


74


.




As can be seen in both

FIGS. 3 and 7

, the receptacles


108


are spaced vertically along the entire length of either the full post section


74


or the half post section


78


. Representatively, the vertical spacing between the receptacles


108


may be approximately 3 inches. In the full post section


74


shown in

FIG. 3

, a second series of receptacles


108


are positioned directly adjacent to the first series of receptacles


108


. The two series of receptacles


108


allow the full post section


74


to receive two separate horizontal support members


72


in a manner to be discussed in greater detail below.




Positioned directly above each of the receptacles


108


is a hook opening


116


. The hook openings


116


are formed in each of the face surfaces


106


and provide access to the interior of the full post section


74


or half post section


78


. Each hook opening


116


includes a substantially circular main opening


118


and a pair of opposed notches


120


each extending horizontally from the main opening


118


. Like the receptacles


108


, the hook openings


116


may be spaced approximately 3 inches apart along the length of both the full post section


74


and the half post section


78


. The full post section


74


includes two sets of hook openings


116


extending along the entire length of the full post section


74


, as with the receptacles


108


.




A series of aligned support slots


122


are positioned between the two vertical rows of receptacles


108


on the full post section


74


of FIG.


3


. The support slots


122


extend at regular intervals along the entire length of the full post section


74


and provide a point of attachment for various components of the space dividing system


60


, as will be discussed in greater detail below. The half post section


78


shown in

FIG. 7

includes a vertical row of support slots


122


positioned adjacent the vertical row of receptacles


108


. Like the support slots


122


formed on the full post section


74


, the support slots


122


on the half post section


78


also provide a point of attachment for other components, as will be discussed in greater detail below. Representatively, the center-to-center spacing of support slots


122


may be approximately 1 inch.




In addition to the pair of face surfaces


106


, both the full post section


74


and the half post section


78


include a pair of opposed side edge surfaces


124


. Each of the edge surfaces


124


includes the seam


86


or


98


joining the outer wall sections


84


or


96


to form both the full post section


74


and half post section


78


. A pair of aligned access notches


126


are formed in each edge surface


124


of both the full post section


74


and the half post section


78


. Each access notch


126


opens from a top end


128


of either the full post section


74


or half post section


78


. The access notches


126


provide an access passageway through the full post section


74


or half post section


78


. In this manner, the access notches


126


allow items, such as electrical or communication wires, to pass through the full post section


74


or half post section


78


in a manner that will be discussed in greater detail below.




Referring back to

FIG. 2

, the lowermost full post section


74


receives a glide housing


130


inserted into its bottom end


132


, while the lowermost half post section


78


receives a similar glide housing


134


also inserted into its bottom end


136


. Each of the glide housings


130


and


134


receive a glide member


138


that engages floor


62


, which can be adjusted to provide balanced support for the panel frame


66


.




As can be seen in

FIGS. 11 and 12

, the glide housing


134


includes a series of webs


140


that define a series of flat contact surfaces


142


. The contact surfaces


142


contact and engage inner surfaces


104


of the half post section


78


and create a friction fit to hold the glide housing


134


in place.




A center web


144


surrounds and holds an internally threaded sleeve


146


as shown in FIG.


12


. The internally threaded sleeve


146


receives a threaded shank


148


of the glide member


138


. The threaded shank


148


is connected to a castor


150


, to provide support for the vertical post


70


on the floor


62


. As can be understood in

FIG. 12

, the castor


150


can be adjusted vertically by screwing the threaded shank


148


into and out of the sleeve


146


in a conventional manner as is known.




The glide housing


134


includes a first shoulder


152


that contacts the bottom end


136


of the half post section


78


to fix the position of the glide housing


134


within the hollow half post section


78


. In addition to the first shoulder


152


, the glide housing


134


includes a second shoulder


154


that extends outward past the half post section


78


. Additionally, a bottom edge


156


of the glide housing


134


includes an outer recess


158


and an inner notch


160


. Recess


158


and notch


160


, as well as shoulder


154


, provide points of attachment for various panel trim components, as will be discussed in greater detail below. Although a description of only glide housing


134


has been provided, the glide housing


130


positioned in the full post section


74


has generally the same construction.




Referring now to

FIGS. 2-6

, each horizontal support member


72


has a general U-shaped cross-section defined by a bottom wall


162


and a pair of opposed sidewalls


164


and


166


, as best shown in FIG.


4


. The horizontal support member


72


generally extends longitudinally between a first end


168


and a second end


170


, as shown in FIG.


6


. As can be seen in

FIG. 6

, the first end


168


and the second end


170


are identical, such that the horizontal support member


72


can be attached between the pair of vertical posts


70


with either the sidewall


164


or the sidewall


166


facing outward.




As seen in

FIGS. 3 and 4

, the sidewalls


164


and


166


are spaced from each other by a distance sufficient to receive the full post section


74


or the half post section


78


therebetween. As illustrated in

FIG. 3

, the first end


168


of both the sidewall


164


and the sidewall


166


includes a pair of attachment members


172


. Representatively, the attachment members


172


are each a locking rivet having an expanded head portion


174


that extends from the sidewall


164


or


166


into an open interior


176


defined by the sidewalls


164


,


166


and the bottom wall


162


. As can be seen in

FIG. 5

, the expanded head portion


174


extends from an inner face


178


of the sidewall


164


. A shaft


180


extends through an opening in the sidewall


164


and is joined to an expanded end


182


that interacts with an outer face


184


of sidewall


162


to hold the attachment member


172


in place. In addition to the shaft


180


, the attachment member


172


includes a standoff


186


that provides the desired spacing of the head portion


174


from the inner face


178


.




As can be seen in

FIGS. 4 and 5

, the four attachment members


172


contained on the first end


168


of the horizontal support member


172


are spaced such that the four attachment members


172


are received within four corresponding receptacles


108


in the full post section


74


. As can be understood in

FIGS. 4 and 5

, the head portion


174


of each attachment member


172


is received behind the retaining flange


110


and the standoff


186


contacts the curved edge


112


of the retaining flange


110


. The horizontal support member


72


is held in place along the full post section


74


by an interference mechanical fit between the four receptacles


108


on the full post section


74


and the four attachment members


172


contained on the first end


168


of the horizontal support member


72


.




Referring now to

FIG. 6

, the preferred method of installing the horizontal support member


72


between a pair of vertical posts


70


will now be described. Specifically, the method of installing the horizontal support member


72


between a pair of full post sections


74


will be described, although the same method would apply to the positioning of a horizontal support member


72


between a pair of half post sections


78


or a combination of a full post section


74


and a half post section


78


.




Initially, as shown at position A, the horizontal support member


72


is positioned at an angle and moved between post sections


74


such that each post section


74


is located between sidewalls


164


,


166


of horizontal support member


72


. The attachment members


172


at the lower end (first end


168


in

FIG. 6

) are positioned above the set of receptacles


108


destined to receive the attachment members


172


. Once the lower end (first end


168


in

FIG. 6

) of the horizontal support member


72


is in the desired location, the upper end (second end


170


in

FIG. 6

) is lowered as shown by arrow


188


to move the horizontal support member


72


to the position shown by reference character B. In position B, the attachment members


172


are positioned out of vertical alignment with the receptacles


108


into which they are to be inserted.




After the horizontal support member


72


is in position B, the horizontal support member


172


is moved laterally as indicated by arrow


190


until the attachment members


172


are vertically aligned slightly above the innermost receptacles


108


, as shown by reference character C. Once the attachment members


172


have been properly aligned above the receptacles


108


, the horizontal support member


72


is moved downward as indicated by arrow


192


until each attachment member


172


is initially received in a receptacle


108


, as indicated by reference character D. The ends of horizontal support member


72


are then pounded downwardly, such as by use of a resilient mallet, to firmly seat each attachment member


172


in one of the receptacles


108


. As horizontal support member


72


is pounded downwardly, each attachment member


172


is moved along the curved retaining flange


110


, and the interference fit therebetween functions to draw the attachment members


172


on sidewalls


164


and


166


inwardly toward each other. This inward movement of attachment members


172


functions to pinch or clamp post section


74


between sidewalls


164


,


166


, to provide a secure mechanical, frictional engagement of horizontal support member


72


with post section


74


.




It is important to note that the horizontal support member


72


can be positioned at numerous locations along the total height of the pair of vertical posts


70


. Since the receptacles


108


are spaced at 3-inch intervals, the horizontal support member


72


can be placed at any 3-inch incremental height along the length of vertical posts


70


. Additionally, it is also important to note that horizontal support member


72


can be positioned between the pair of vertical posts


70


without requiring the vertical posts


70


to be separated or any other movement of vertical posts


70


. Thus, horizontal support members


72


can be added to or removed from the panel frame


66


after the panel frame


66


has been formed without first disassembling the panel frame


66


, or the location of existing horizontal support members


72


can be changed. This feature is extremely important, since the panel frame


66


can be modified without being first disassembled.




Additionally, as can be seen in

FIG. 2

, the horizontal support member


72


positioned on the bottom of the panel frame


66


can be inverted relative to the horizontal support member


72


positioned at the top end of panel frame


66


. The lower horizontal support member


72


is inverted such that it can support an electric wireway, in a manner to be discussed in greater detail below. However, it should be noted that the spacing between the lowermost receptacles


108


is increased relative to the spacing between the remaining receptacles


108


in order to accommodate the inversion of the horizontal support member


72


near the bottom of the panel frame


66


.




Referring now to

FIGS. 3 and 4

, each of the sidewalls


164


and


166


of the horizontal support member


72


includes a channel


194


extending along the entire length of horizontal support member


72


. The channel


194


includes a lip


196


extending upwardly past the bottom


198


of the channel


194


. The lip


196


defines a U-shaped lower area of channel


194


that allows various components to be mounted to the horizontal support member


72


, as will be discussed in greater detail below.




Each of the sidewalls


164


and


166


includes an access opening


198


extending inward from both the first end


168


and the second end


170


, as can be seen in

FIGS. 3 and 6

. As can best be seen in

FIG. 6

, when the horizontal support member


72


is properly positioned along the pair of vertical posts


70


and mounted thereto as described above, the access opening


198


formed in each end of the horizontal support member


72


is aligned with one of the hook openings


116


formed in the vertical post


70


.




Referring now to

FIGS. 2 and 3

, the bottom wall


162


of each horizontal support member


72


includes a U-shaped cut-out


200


extending inward from both the first end


168


and the second end


170


. Each cut-out


200


terminates along a curved edge


202


. As can be understood in

FIGS. 2 and 29

, the curved edge


202


is spaced far enough inward from either the first end


168


or the second end


170


such that when the horizontal support member


72


is connected between the pair of vertical posts


70


, a gap exists between the edge surface


124


of the vertical post


70


and the curved edge


202


. This gap allows wires or other components to be threaded between the spaced horizontal support members


72


.




Additionally, the cut-outs


200


allow each horizontal support member


72


to be attached between the pair of vertical posts


70


without first separating the vertical posts


70


. As shown in position A of

FIG. 6

, the full post section


74


is received in the cut-out


200


along the first end


168


to permit the horizontal support member


72


to be angled as shown. Once positioned between the vertical posts


72


, the horizontal support member


72


can be properly aligned as discussed above.




Referring back to

FIG. 2

, a pair of corner posts


204


are used to create a 90° connection between adjacent panel frames


66


. Specifically, the pair of corner posts


204


are used to connect the half post sections


78


contained in each of the panel frames


66


positioned at the 90° corner. Referring to

FIG. 13

, each corner post


204


includes an outer web


206


joined to a center portion


208


by a plurality of radial webs


210


. In the preferred embodiment of the invention, the corner post


204


is formed from extruded aluminum.




The corner post


204


defines four individual receptacles


212


that are each sized to receive the edge surface


124


of the half post section


78


. In the preferred embodiment of the invention, each of the half post sections


78


is joined to the corner post


204


by a connector


214


having a threaded shaft


216


and an expanded head portion


218


. The threaded shaft


216


passes through aligned holes


220


contained in each of the edge surfaces


124


. The threaded shaft


216


passes through an opening


222


contained in the receptacle


212


formed by the outer web


206


of the corner post


204


. A nut


224


receives the threaded shaft


216


, such that the nut


224


and connector


214


secure the half post section


78


to the corner post


204


. As can be understood in

FIG. 2

, the pair of corner posts


204


are spaced vertically along the overall height of the vertical posts


70


to provide the required points of connection between the two panel frames


66


.




Tiles


68


are mounted to each panel frame


66


in a manner illustrated in

FIGS. 14-22

. Each tile


68


is mounted between the upper and lower horizontal support members


72


to provide a solid wall construction for each of the panel frames


66


, as is conventional in space dividing or partitioning systems. However, as can be seen in

FIG. 15

, each tile


68


includes a planar rear surface


226


that is placed in close contact with the panel frames


66


. Each tile


68


is hung on the panel frame


66


by a plurality of tile retaining hooks


228


. Each of the tile retaining hooks


228


is a component separate from both the tile


68


and the panel frame


66


. Therefore, unlike the tiles used in previous panel systems, the rear surface


226


of the tile


68


is generally planar such that when tiles


68


are stacked and shipped, there is no danger that hooks contained on the tiles can damage adjacent tiles or can be bent or snapped off, as is the case with tiles used in prior art space dividing or partitioning systems. Further, the elimination of permanently mounted hooks allows tiles


68


to be closely stacked, in that facing surfaces of adjacent tiles are in direct contact with each other. In the case of tiles having permanently-mounted hooks, the hooks extend from a rear surface of the tile and prevent facing surfaces of adjacent tiles from contacting each other. This provision of separate retaining hooks


228


thus functions to significantly compress the space required for stacking tiles for shipment or storage.




Each tile retaining hook


228


generally includes a main body portion


230


having a support hook


232


extending therefrom. The main body portion


230


is inserted into the vertical post


70


such that the tile retaining hook


228


is retained within the vertical post


70


. The support hook


232


is received within a recessed hook channel


234


formed in the tile


68


. As can be seen in

FIG. 16

, the tile


68


includes a pair of hook channels


234


positioned normally to each other. Since each tile


68


includes hook channels


234


extending horizontally and vertically, the orientation of the tile


68


can be rotated 90° while still being able to be supported by the tile retaining hooks


228


positioned on the panel frame


66


.




Each tile retaining hook


228


is inserted into either the full post section


74


or the half post section


78


as follows. Initially, the tile retaining hook


228


is oriented in the direction shown in

FIG. 17



a.


When positioned as shown, the main body portion


230


can be inserted through both the access opening


198


formed in the horizontal support member


72


and the hook opening


116


formed in the full post section


74


. Specifically, the main body portion


230


passes through the pair of notches


120


contained on the hook opening


116


.




Once the tile retaining hook


228


is positioned within both the access opening


198


and the hook opening


116


, the tile retaining hook


228


is rotated 90° to the locked position shown in

FIG. 17



b.


When rotated to the position shown in

FIG. 17



b,


the tile retaining hook


228


is locked in position, as shown in

FIGS. 21 and 22

. As can be seen in these figures, the tile retaining hook


228


includes a first, inner pair of locking tabs


236


that extend outwardly from the main body


230


. The first pair of locking tabs


236


extend through access opening


198


and hook opening


116


, and engage the inner surface


92


of the full post section


74


. A second, outer pair of locking tabs


240


extend from the main body


230


between first locking tabs


236


and support hook


232


and are spaced from the first pair of locking tabs


236


by a distance slightly greater than the wall thickness of the full post section


74


, as can be seen in FIG.


21


. The second pair of locking tabs


240


has a thickness corresponding to the space between the facing surfaces of full post section


74


and horizontal support member


72


. Thus, when the tile retaining hook


228


is inserted into the assembled panel frame


66


, if the panel frame


66


has been improperly constructed, the tile retaining hook


228


will not rotate into the position shown in

FIG. 17



b,


since the access opening


198


and the hook opening


116


will be improperly aligned. Additionally, if the panel frame


66


has been improperly constructed, the spacing between the full post section


74


and the horizontal support member


72


may be improper, such that the second pair of locking tabs


240


will not fit in the space between the full post section


74


and the horizontal support member


72


.




When the tile retaining hook


228


is properly inserted as shown in

FIGS. 21 and 22

, tile retaining hook


228


is turned to its locked position of

FIG. 17



b,


in which the edges of post section


74


adjacent hook opening


116


are received in the space between first locking tabs


236


and second locking tabs


240


. In addition, second locking tabs


240


are engaged with the rear surface of the wall of horizontal support member


72


, which is received within a notch


241


formed between the upper one of second locking tabs


240


and support hook


232


. Thus, when tile retaining hooks


228


are in the locked position of

FIG. 21

, tile retaining hooks


228


function to interlock horizontal support member


72


with post


70


so as to prevent relative movement between horizontal support member


72


and post


70


. Tile retaining hooks


228


thus perform the dual function of providing an interlock between post


70


and horizontal support member


72


, as well as providing a hook structure for mounting tiles


68


.




When tile retaining hook


228


is in its locked position of

FIG. 17



b,


the support hook


232


is oriented upward and can be received within the hook channel


234


formed in tile


68


. As shown in

FIG. 21

, the support hook


232


is substantially smaller than channel opening


242


, such that when the tile


68


is installed, the tile


68


slides downward until the support hook


232


engages an upper wall


244


of the hook channel


234


. The upper wall


244


includes an outer lip


246


that prevents the support hook


232


from being pulled out of the hook channel


234


after the tile


68


has been installed. The hook channel


234


is formed in a tile corner connector


248


that is used in constructing each individual tile


68


in a manner that will be discussed in greater detail below. The tile corner connector


248


is formed from a plastic material and includes the pair of hook channels


234


positioned normally to each other.




Referring to

FIG. 22

, the tile retaining hook


228


positioned near the bottom edge of tile


68


does not support the weight of the tile


68


when the tile


68


is hung on the panel frame


66


. As can be seen in

FIG. 22

, the support hook


232


does not interact with any portion of the tile corner connector


248


to support the weight of the tile


68


. Rather, the support hook


232


is received within the hook channel


234


and functions to prevent lateral movement of the tile


68


, since the support hook


232


cannot move laterally within the hook channel


234


. In addition, a lip


247


formed at the end of hook channel


234


opposite lip


246


overlaps the upper end of the lower support hook


232


to prevent outward movement of the lower end of tile


68


. Since the tile retaining hook


228


located near the lower portion of the tile


68


is inserted into the panel frame


66


in the identical manner as the tile retaining hook


228


supporting the upper portion of the tile


68


, the lower tile retaining hook


228


also assures that the horizontal support member


72


is correctly aligned with the full post section


74


and provides an interlock therebetween.




Each tile


68


is installed by first positioning tile


68


such that tile retaining hooks


228


are first inserted into hook channels


234


and lips


246


,


247


are located above the upper and lower support hooks


232


, respectively. Tile


68


is then moved vertically downwardly such that upper and lower tile retaining hooks


228


are engaged within hook channels


234


as shown in

FIGS. 21 and 22

, respectively, to engage tile


68


with panel frame


66


. Tiles


68


are removed by reversing these steps.




As was discussed earlier, the full post section


74


, as well as the half post section


78


, includes a series of hook openings


116


spaced along the entire length of the post. Thus, it can be understood that a horizontal support member


72


and tile retaining hooks


228


could be aligned with any one of the hook openings


116


, such that tiles


68


having different lengths and widths can be supported along the panel frame


66


by simply installing a horizontal support member


72


and moving the tile retaining hooks


228


to the desired position. In this manner, the space dividing or partitioning system


60


of the present invention can be configured to support many types of tile configurations based on user requirements.




Each tile


68


is constructed in a manner as shown in

FIGS. 18-20

. Each tile


68


generally includes a rectangular tile frame


250


constructed from four frame members


252


each joined by one of the tile corner connectors


248


. Each frame member


252


generally includes a channel


254


and an inwardly extending attachment flange


256


formed from a single piece of material. Representatively, each frame member


252


may be formed from twenty gauge cold rolled steel. As can be seen in

FIG. 20

, the channel


254


defines a passage


258


. The attachment flange


256


extends from the channel


254


. The tile corner connector


248


includes a pair of stem portions


259


each extending from main body portion


260


to form a 90° angle. The stem portion


259


is received within passage


258


defined by the channel


254


and creates a friction fit therebetween, as best shown in FIG.


19


.




Each attachment flange


256


includes a raised portion


262


along its first end


263


that overlaps a second end


265


of the attachment flange


256


of the adjacent frame member


252


, as best shown in FIG.


19


. The raised portion


262


is set off from the remaining portion of the attachment flange


256


by a bend


266


. Thus, once the components of an entire tile frame


250


are assembled as shown in

FIG. 18

, the raised portion


262


on the first end


263


of each attachment flange


256


can be spot welded to the second end


265


of the attachment flange


256


of the adjacent frame member


252


to securely form the tile frame


250


. Corner connectors


248


are thus trapped in position due to engagement of stem portions


260


within channels


254


of adjacent frame members


252


. Corner connectors


248


have a cross-section generally corresponding to that of channel


254


, such that the exposed area of each corner connector


248


functions to provide a completed


90


° corner between adjacent ends of channels


254


.




A slot


261


is formed in the rear wall of each channel


254


adjacent each end thereof. Slot


261


functions to expose hook channels


234


, which are formed in each stem


260


of each corner connector


248


.




After the tile frame


250


has been constructed in the manner identified above, a tile core


264


and an acoustically absorptive sponge member


267


are inserted into the assembled tile frame


250


. A fabric cover member


268


is stretched across the front of the sponge member


267


and attached to the frame member


252


in a conventional manner, as shown in FIG.


20


. Representatively, the fabric cover member


268


may be attached to the frame member


252


by a conventional adhesive.




Two types of possible configurations for the space dividing or partitioning system


60


of the present invention are shown in

FIGS. 23 and 24

. In

FIG. 23

, a configuration having a continuous main wall


270


formed from a series of panels


64


each including tiles


68


is connected to at least a pair of cross walls


272


, each of which are also formed from one or more interconnected panels


64


, each including a tile


68


.




In

FIG. 24

, a wall is constructed having a reduced height panel


274


. Reduced height panel


274


is formed from a vertical post


70


having only one full post section


74


or half post section


78


, rather than the two joined post sections as previously described. Since each vertical post


70


is formed on site by joining two individual post sections with a splice section, as was shown and described in

FIG. 2

, the reduced height wall section


274


can be easily constructed on site by simply using only one of the two vertical post sections.




Attached to the top of each panel


64


is a panel top cap


276


, as best shown in

FIGS. 23 and 28

. The panel top cap


276


provides decorative trim for the upper edge of each panel


64


, and also functions to enclose the upwardly facing channel defined by the topmost horizontal support member


72


. As shown in

FIG. 28

, the panel top cap


276


includes a curved upper wall


278


that contacts and is supported by a top end


280


of the horizontal support member


72


. The panel top cap


276


includes a pair of attachment tabs


282


that flex outward and extend along the entire length of the panel top cap


276


. As can be seen in

FIGS. 28 and 28



a,


the attachment tabs


282


engage the sidewalls


164


,


166


of the horizontal support member


72


between the top end


280


and a bulge


284


formed in each sidewall


164


and


166


. When the panel top cap


276


is attached as shown in

FIGS. 28 and 28



a,


the attachment tabs


282


flex outward and exert a bias force against the sidewalls


164


and


166


to hold the panel top cap


276


in place along the horizontal support member


72


.




Referring back to

FIG. 23

, a three-way intersection post cover


294


is positioned over a three-way interconnection of panels


64


. The three-way post cover


294


also includes a plurality of tongues


288


that interact with the adjacent panel top caps


276


to secure the panel top caps


276


in position as shown.




Referring now to

FIGS. 24 and 29

, an end-of-run trim section


296


extends vertically between the upper panel top cap


276


and the lower panel top cap


276


. The end-of-run trim section


296


is joined extends between an outer corner trim section


298


and an inner corner trim section


300


. The lower panel top cap


276


terminates at a post cover


302


.




Referring now to

FIG. 29

, the end-of-run trim section


296


extends vertically and includes a pair of tabs


304


that extend along the length of the end-of-run trim section


296


and engage the face surfaces


106


of the full post section


74


. When the end-of-run trim section


296


is installed, tabs


304


flex outward and engage receptacles


108


, to retain the end-of-run trim section


296


in place along the full post section


74


.




In addition to the sections of trim placed over the top edge of each panel


64


, a series of vertical trim sections are used to cover each vertical corner post


204


at each corner in the space dividing or partitioning system


60


of the present invention. As shown in

FIGS. 24 and 30

, a three-sided corner post cover


306


is attached to the pair of corner posts


204


at the end of a single wall. The corner post cover


306


extends from the post cover


302


to the ground to provide a finished appearance for the corner of the reduced height panel


274


. Corner post cover


306


includes a pair of tabs


308


that snap into a pair of cavities


310


formed in the outer web


206


of the corner post


204


as shown in FIG.


32


.




Like the three-sided post cover


306


, a two-sided post cover


312


is used to create a finished appearance between a pair of orthogonally joined panels


64


, as shown in

FIGS. 23 and 31

. As can best be seen in

FIG. 31

, the two-sided corner post cover


312


also includes a pair of tabs


308


that engage the cavities


310


formed in the outer web


206


of the corner post


204


.




Finally, a one-sided corner post cover


314


is used to provide a finished look at the intersection of three joined panels


64


, as shown in

FIGS. 23 and 35

. The one-sided post cover


314


includes a pair of tabs


316


that engage two of the cavities


310


formed in the outer web


206


of the corner post


204


. The tabs


316


are biased to snap into the cavity


310


to hold the one-sided trim cover


314


in place along the pair of corner posts


204


.





FIGS. 25 and 28

illustrate a base cover


318


that is attached to the lowermost inverted horizontal support member


72


of the panel frame


66


. The base cover


318


is positioned below the tile


68


and is spaced slightly above the floor


62


. As will be discussed in greater detail below, the base cover


318


not only provides decorative trim below the horizontal support member


72


, but also functions to enclose an electrical and communication wireway.




As can be seen in

FIG. 28

, the base cover


318


is formed from a pair of base sides


320


and a base bottom


322


. The base sides


320


and the base bottom


322


are separately formed from extruded PVC and are subsequently joined to form the structure shown. Specifically, each of the base sides


320


includes a tongue


324


that is received in a corresponding groove


326


formed in the base bottom


322


, as shown in

FIG. 28



c.


The tongue


324


includes an expanded end


328


that prevents the base side


320


from becoming laterally detached from the base bottom


322


. During assembly of the base cover


318


, the tongue


324


, including the expanded end


328


, is slid longitudinally into the groove


326


in the base bottom


322


and subsequently joined to the base bottom


322


by a hot melt or adhesive process.




The base cover


318


is supported between adjacent vertical posts


70


by the interaction between the base bottom


322


and the glide housing


130


or


134


contained on each vertical post


70


. Specifically, the base bottom


322


includes a pair of upwardly extending tabs


330


that engage the second shoulder


154


of the glide housing


134


as shown in

FIG. 28



c.


Additionally, the base bottom


322


includes alignment tabs


332


that are received in the notches


160


of the glide housing


134


.




Referring back to

FIG. 28

, the area of each base side


320


adjacent the outer edge of base bottom


322


defines a living hinge which allows the base sides


320


to flex outward, as shown in phantom. Thus, when the base sides


320


flex outward, the open area below the lower inverted horizontal support member


72


is accessible, as will be discussed in detail below. Each of the base sides


320


includes a sidewall


334


that extends upward and terminates at a top wall


336


as shown in

FIG. 28



b.


Top wall


336


is joined to an inner wall


338


that includes a latch portion


340


. The latch portion


340


includes a tab


342


extending from a receipt cavity


344


. When the base side


320


is pushed inward, the tab


340


contacts the end


280


of the inverted lower horizontal support member


72


, such that the end


280


is received and retained within the receipt cavity


344


. As was previously discussed, the lower horizontal support member


72


is inverted such that the opening to the horizontal support member


72


faces downward.




To open either of the base sides


320


, the top wall


336


can be grasped and pulled outward to cause the latch portion


340


to flex downward, thereby permitting the tab


342


to pass below the top end


280


of the horizontal support member


72


.




Referring now to

FIGS. 23 and 33

, a base corner cover


346


is positioned between the pair of base covers


318


at the corner between adjacent panels


64


. As shown in

FIGS. 33 and 34

, the base corner cover


346


includes a pair of upper attachment tabs


348


that pass through the support slots


122


contained in each of the half post sections


74


. A second pair of attachment tabs


352


is received in a passageway


354


in the glide housing


134


as shown in

FIG. 34

, and a snap-type retainer arrangement is provided between the end of each attachment tab


352


and a wall of passageway


354


. Outer wall


356


of the base corner cover


346


is spaced from the half post section


74


by a distance sufficient to permit passage of one or more wires


358


therebetween.




In addition to the base corner cover


346


, a base trim cover


360


is positioned between adjacent sections of the base cover


318


, as shown in

FIGS. 23 and 38

. The base trim cover


360


includes a pair of upper attachment tabs


362


that each engage support slots


122


in one of the half post sections


74


. A lower pair of attachment tabs


364


are received in the passageways


354


formed in the glide housing


134


, and a snap-type retainer arrangement is provided between the end of each attachment tab


352


and the wall of each passageway


354


, to further retain the base trim cover


360


. As seen in

FIG. 38

, outer wall


366


of the base trim cover


360


is spaced from the half post section


74


by a distance sufficient to allow passage of the one or more wires


358


.





FIGS. 39-42

illustrate a clamp mechanism


368


used to secure one of the half post sections


78


to another wall panel


64


. The clamp mechanism


368


includes a clamp member


376


positioned to extend through the access notch


126


formed near the top end


128


of the half post section


78


. The clamp member


376


extends generally horizontally and terminates with a depending lip


378


. The lip


378


engages the recess lip


196


of a horizontal support member


72


forming a part of wall panel


64


. A sleeve


380


extends through the clamp member


376


and receives a portion of a shoulder bolt


382


. Shoulder bolt


382


includes an internal hex


384


. A spring washer


386


is positioned between the head of the shoulder bolt


382


and the sleeve


380


.




The shoulder bolt


382


includes a threaded shaft


388


that is threadedly received in a T-nut


390


, which is secured to a clamp guide weldment


392


. The clamp guide weldment


392


includes a pair of upwardly extending tabs


394


that each receive a threaded connector


396


. Threaded connectors


396


pass through openings in the edge surface


124


of the half post section


78


to secure the clamp guide weldment


392


in position. Thus, as can be understood in the figures, as the shoulder bolt


382


is rotated, the threaded interaction between the threaded shaft


382


and T-nut


390


causes clamp member


376


to move downward into contact with the lip


196


. By further tightening of the shoulder bolt


382


, the clamp member


376


is securely moved into engagement with lip


196


to securely fix the upper end of half post section


78


to wall panel


64


.




A fixed lower clamp member


398


having a lip


399


is mounted within the half post section


78


and engages lip


196


of a lower horizontal support member forming a part of wall panel


64


. The lower clamp member


398


is not vertically adjustable, but is positioned to engage the lower lip


196


to fix the lower end of the half post section


78


to wall panel


64


when bolt


382


is tightened down.




With this arrangement, half post section


78


is used in combination with the upper clamp mechanism


368


and lower clamp member


398


to position a panel at any position between a pair of vertical posts


70


, including at “off module” locations.





FIG. 43

illustrates two types of overhead storage members, referred to by reference numerals


400


and


402


, that can be used in combination with the space dividing or partitioning system


60


of the present invention. Overhead storage member


400


is shown mounted between a pair of vertical posts


70


. This type of mounting arrangement is commonly referred to as “on-module” mounting, since the overhead storage member


400


is mounted directly between the pair of vertical posts


70


. The overhead storage member


402


is shown as mounted “off-module”, since the overhead storage member


402


is not directly connected to a pair of vertical posts


70


. The “off-module” mounting arrangement of overhead storage member


402


allows the overhead storage member


402


to be positioned in any location based on user requirements.





FIG. 44

shows the mounting arrangement for the overhead storage member


400


. The overhead storage member


400


includes a pair of hanging brackets


404


that are connected to a back wall


406


of the overhead storage member


400


. As can best be seen in

FIG. 46

, each of the hanging brackets


404


includes a plurality of upwardly extending tabs


408


that extend into openings


410


formed in the back wall


406


. Each of the tabs


408


includes an upper end


412


that maintains the hanging bracket


404


in engagement with the back wall


406


. A plurality of connectors


414


are used to secure the hanging brackets


404


to the back wall


406


once the hanging brackets


404


have been inserted into the back wall


406


as shown.




The hanging brackets


404


include a second set of depending tabs


416


extending opposite to the first set of tabs


408


. The second set of tabs


416


are each received in one of the support slots


122


formed in the full post section


74


or half post section


78


. In the embodiment shown in

FIG. 46

, the tabs


416


of overhead storage member


400


are received within the support slots


122


of the full post section


74


. Each of the tabs


416


includes a lower end


418


that contacts the inner surface


92


of the full post section


74


to secure the overhead storage member


400


as shown. As can be understood in

FIG. 46

, the hanging brackets


404


provide the required spacing between the overhead storage member


400


and tile


68


.





FIG. 45

illustrates the mounting arrangement for the overhead storage member


402


. The mounting arrangement for the overhead storage member


402


includes a pair of hook brackets


418


secured to a back wall


420


of overhead storage member


402


. Each of the hook brackets


418


includes a generally vertical support plate


422


having a plurality of tabs


424


extending forwardly therefrom. The tabs


424


pass through openings


426


contained in back wall


420


. As was the case with the hanging brackets


404


described in

FIG. 46

, the tabs


424


each include an upper end


428


that maintains the tabs


424


in engagement with the back wall


420


. A plurality of connectors


430


secure each of the hook brackets


418


to the back wall


420


.




As

FIGS. 45 and 48

illustrate, each hook bracket


418


includes an upper support flange


432


and a lower support flange


434


extending from the support plate


422


. Both the upper support flange


432


and the lower support flange


434


include a depending lip


436


. As can be seen in

FIG. 48

, both the upper support flange


432


and the lower support flange


434


extend from the support plate


422


a distance greater than the thickness of tile


68


. As

FIG. 48

illustrates, the lip


436


of the upper support flange


432


is received in the channel


194


of horizontal support member


72


. As previously discussed, the channel


194


extends along the entire longitudinal length of the horizontal support member


72


. The extended lip


196


of channel


194


prevents the lip


436


of the upper support flange


432


from leaving the channel


194


.




An intermediate horizontal support member


72


is positioned below the top horizontal support member


72


as shown in FIG.


48


. The lip


436


of the lower support flange


434


is received in channel


194


of intermediate horizontal support member


72


in a manner similar to that described above. In this manner, the upper support flange


432


and the lower support flange


434


provide support for the overhead storage member


402


.




As can be seen in

FIGS. 43 and 48

, an upper tile


438


having a width less than the width of the overhead storage member


402


is attached to top portion of the panel frame. A lower tile


440


extends down to the bottom edge of the panel frame. The separation between the upper tile


438


and the lower tile


440


allows the lower support flange


434


to pass therebetween.




Since each of the horizontal support members


72


includes a channel


194


, the overhead storage member


402


can slide between the aligned horizontal support members


72


contained on adjacent panels


64


, since the overhead storage member


402


is supported only by the interaction between the hook brackets


418


and the channels


194


. In this manner, the overhead storage member


402


can be moved between the separate panels


64


as shown in FIG.


43


and does not have to be mounted “on-module”, as is the case with overhead storage member


400


.




As can be seen in

FIG. 49

, a threaded locking member


440


passes through the rear wall


420


of overhead storage member


402


and through support plate


422


for engagement within channel


194


. The locking member


440


is used to secure the overhead storage member


402


once the overhead storage member


402


is in the desired position. Specifically, the locking member


440


is tightened in a threaded boss


441


, which may be a nut welded to support plate


422


, until an end portion


442


contacts the channel


194


. This functions to draw overhead storage member


402


outwardly, resulting in engagement of lip


436


with channel lip


196


, to frictionally lock lips


196


,


436


together to prevent upward movement of the overhead storage member


402


relative to the channel


194


. Locking member


440


and boss


441


extend through an opening


444


in the back wall


420


such that the locking member


440


can be tightened from the open interior of the overhead storage member


402


.




The drawings illustrate mounting of overhead storage member


402


in channels


194


. It should be understood, however, that any component or accessory may be mounted in channels


194


at any height. Examples include shelving, cabinets, paper management devices, computer or computer monitor supports, etc. To mount any such component or accessory, the system


60


need only be configured to provide a horizontal support member


72


at each desired elevation, and tile


68


must be configured to expose channels


194


to enable such components to be mounted.




The base covers


318


attached near the bottom end of each panel


64


define a raceway


446


through which electrical and communication lines may pass, as can be seen in

FIGS. 50



a


and


50




b.


Each of the base covers


318


includes a pair of receptacle openings


448


and corresponding receptacle covers


450


that may be removed to provide access to the raceway


446


. If the receptacle opening


448


is not needed, the receptacle cover


450


can remain within the receptacle opening


448


, as best shown in

FIGS. 50



a


and


51


. The receptacle cover


450


is designed to match the overall appearance of the base side


320


such that the receptacle cover


450


provides an aesthetically pleasing appearance.




As can be seen in

FIG. 51

, the base cover


318


is constructed such that either or both of the sidewalls


320


may include the receptacle openings


448


and receptacle covers


450


, or the base cover


318


may be formed without any receptacle openings. When the space dividing or partitioning system


60


of the invention is constructed, the base cover


318


is positioned such that the receptacle openings


448


face the desired direction to provide access to the raceway


446


.




As was previously discussed, the lowermost horizontal channel


72


of each panel frame


66


is inverted such that the U-shaped cross-section of the horizontal support member


72


faces downward. In the preferred embodiment of the invention, each horizontal support member


72


is connected to the two lowermost receptacles


108


of either the full post section


74


or the half post section


78


, as shown in

FIGS. 50



b


and


14


. Although in the preferred embodiment the lowermost horizontal channel member


72


is attached to the two lowest receptacles


108


, each of the full post sections


74


and half post sections


78


are constructed such that the inverted horizontal support members


72


could be moved upward and connected to the second and third lowest receptacles


108


while leaving the lowest receptacle


108


open. If the inverted horizontal support member


72


is moved upward as described, the size of the raceway


446


could be expanded by using a base cover


318


having longer base sides


320


.




As shown in

FIG. 50



b,


the electric power connection for the space dividing or partitioning system


60


includes a series of rigid wireways


452


joined by a series of jumpers, such as shown at wire


358


. As shown in

FIG. 51

, the rigid wireway


452


includes an electrified power strip


454


supported between a pair of rails


456


. A cover member


458


is supported between the rails


456


on each side of the electrified power strip


454


.




A receptacle module


460


can be positioned in contact with the electrified power strip


454


as shown in

FIGS. 50



b


and


54


. Receptacle module


460


includes a conventional electrical receptacle


462


that can receive conventional electrical plugs. The receptacle


462


extends past the base side


320


through a specially designed cover member


464


that fits in the receptacle opening


448


formed in the base cover


318


. In addition to supporting the receptacle module


460


and the receptacle


462


, cover member


464


defines an opening


466


that receives and secures a communication outlet


468


. The communication outlet


468


is connected to a voice or data cable


470


that provides connections to telephones, modem lines or other types of communication devices, such as computer terminals. The data cable


470


runs within the raceway


446


along with the electric power supply.




A pair of electrical hanging brackets


472


support each of the rigid wireways


452


within the raceway


446


. As shown in

FIGS. 52 and 53

, each electrical hanging bracket


472


includes a pair of attachment hooks


474


that engage openings


476


formed near the end


280


of each sidewall


164


and


166


of the horizontal support member


72


. Specifically, each attachment hook


474


includes a projecting emboss


478


that snaps into and is retained within the opening


476


. Channel


480


receives the end


280


of the horizontal support member


72


, as shown in FIG.


52


. In this manner, electrical hanging bracket


472


is releasably engaged with horizontal support member


72


using a vertical push-on motion, which results in deflection of the fingers of hooks


474


until embosses


478


snap into and through openings


476


. Electrical hanging brackets


472


can be removed by pushing the hook fingers inwardly to disengage embosses


478


from openings


476


.




The electrical hanging brackets


472


include a pair of depending arms


482


that receive and engage a molded end cap


484


attached to each end of the rigid wireway


452


. Each of the arms


482


includes an alignment finger


486


and an extending emboss


488


. When the electrical hanging bracket


472


is pushed downward into engagement with the molded end cap


484


, the alignment fingers


486


are positioned on opposite sides of a center rail


490


of the end cap


484


. The embosses


488


each engage a projection

499


. Wire guide


492


is received in the space between adjacent tiles


68


, and functions both to support wire


499


from components being mounted to post section


74


.




Although the electrical connections for the space dividing or partitioning system


60


have been discussed as passing through the wireway


446


contained near the bottom of each panel


64


, other wires such as


499


may also pass be at upper locations to provide voice or data to various locations along each of the panels


64


if desired. As shown in

FIG. 57

, as the wire passes upward between the horizontal support members


72


, one or more wire support clips


504


retain the wire


499


. The wire support clips


504


include an expanded head


506


that passes through an opening


508


formed in the bottom wall


162


of the horizontal support member


72


. The wire support clips


504


include a first pair of arms


510


and a second pair of arms

The mounting of tiles


68


to vertical posts


70


as shown and described defines a space, such as shown at


522


, between the outer face of each post


70


and the inner, facing surface of each tile


68


. In this manner, wires such as


358


can be passed through the space such as


522


, such that wires


358


can pass freely between adjacent panel sections.




Upon reaching one of the horizontal support members


72


, the wire


358


passes through the cut-out


200


formed in the bottom wall


162


of the horizontal support member


72


, as best shown in FIG.


29


. As can be seen in

FIG. 29

, the size of the cutout


200


is larger than the size of the wire


358


, such that the wire


358


can pass through the open area between the curved edge


202


and the edge surface


124


of the full post section


74


. Upon reaching the top of one of the vertical posts


70


, the wire


358


can pass through the access notch


126


contained in either the full post section


74


or the half post section


78


, as shown in

FIGS. 27 and 57

. Thus, wire


358


can pass through the vertical posts below the top end


128


and into the channel defined by horizontal support member


72


, and be covered by the panel top cap


276


.




Although not shown in the figures, it is contemplated that a horizontal support member


72


could be mounted between the vertical posts


70


at an intermediate location corresponding generally to the height of a conventional desk. With the horizontal support member


72


positioned as such, electric power and data connections can then be routed to the desk top level. This type of configuration can be constructed by simply mounting a horizontal support member


72


between the vertical posts


70


at the desired location, without any additional steps being taken or the complete disassembly of already assembled panel frames


66


.




Although not illustrated in the drawings, it is contemplated that a conventional cover will be applied to vertical posts


70


between the edges of adjacent tiles


68


, so as to conceal support slots


122


.




Although only a few possible configurations for the space dividing and partitioning system


60


of the present invention have been shown and described in the figures, it is easily understood that the number of possible configurations for the system


60


depends only upon the imagination and requirements of the user. As can be understood, the space dividing and partitioning system


60


includes only relatively few parts that can be used interchangeably to form and connect panels in numerous configurations. Thus, the business or office owner only needs to stock a limited number of different components to be able to knock down and reconfigure an open office space.
