Similar reference characters indicate corresponding parts throughout the several views ofthe drawings.
Dimensions of certain of the parts as shown in the drawings may have been modified or exaggerated for the purposes of clarity of illustration.
Referring now to the drawings, there is shown in FIG. 1 a wall structure embodying the instant invention and generally indicated by reference numeral 10. The wall structure includes one or more units, each of which includes a panel assembly generally indicated by reference numeral 12 and a post assembly generally indicated by reference numeral 14.
As best seen in FIG. 2, panel assembly 12 includes a core or support frame comprising upper and lower (as viewed in FIG. 2) cross pieces 20, 21, respectively, and one ormore connecting members 22 all of which are joined together by suitable fasteners such as, for example, bolts, screws, glue or the like, to form the support for a Vpair of substantially planar panel members 16 sandwiched about the frame. Panel members 16 are formed of a suitable, inexpensive, relatively light-weight and strong material such as, for example, quarter-inch plywood, while the cross pieces 20, 21, and connecting members 22 are formed of a suitably inexpensive, strong, relatively lightweight material such as, for example, redwood. Members 20, 21 and 22 have cross sectional dimensions such that, when the panel is in assembled form, panel members 16 are separated by a distance slightly greater than the width of post 14 to permit panels 16 to overlap post assembly 14 as described hereinafter.
Cross pieces 20 and 21 have, at each of their ends, .portions of reduced width thereby forming upper and lower (as viewed in FIGS. 1 and 2) alignment tongues 24 and 25, respectively. Located in cross pieces 20, 21, intermediate the panel members 16 and adjacent tongues 24, 25, are, respectively, upper and lower apertures or receptacles 26, 27, formed in members 20 and 21. These receptacles extend upwardly from the bottom (as viewed in FIG. 2), and partially through the thickness of cross pieces 2li and 21. As best seen in FIG. 3, receptacles 26 and 27 are provided with ferrules 23 formed of a material of suitable strength such as, for example, steel, to strengthen and preserve the configuration of the receptacles.
Attached to the upper side of member 20, as viewed in FIG. 2, is a channel member 30 extending along all or at least a portion of the full width portion of cross piece 2t) and having a U-shaped cross `sectional configuration which provides a channel or slot 32 on cross piece 20. Alternatively, member 30 may be formed of a pair of strips attached to member 20 which together with the upper surface of member 20 provides the channel 32 on member 20. Member 30 is formed of a suitably inexpensive strong and lightweight material such as, for example, Wood or plastic. Members 2t) and 30 are attached to each other by suitable fasteners such as, for example, by glue, screws, bolts or the like.
As best seen in the embodiment shown in FIG. 5, post assembly 14 includes a pair of upst-anding post members 36 formed of a material of suitable strength such as, for example, steel, each having a substantially U-shaped cross sectional configuration to form a channel or slot 38 extending the length of post members 36. As best seen in FIG. 4, post members 36 have a generally rectangular shape in cross section and are joined at 4the apex portions o-f their U-shape as, 'for example, by welding such that post assembly 14 forms substantially a square in cross section. Fach of post members 36 has L-shaped lips 4t) running the length of members 36 which are secured to or preferably formed integrally with the free ends of the legs of members 36 to forni guides or retaining shelves in channel 38.
Mounted on each of .post mem-bers 36 are upper and lower (as viewed in FIG. 5) L-shaped bracket members 44, 46, respectively, each of which includes on one leg thereof upstanding pins `43, Si), which may be formed integrally with the brackets or preferably secured thereto as, for example, by welding, screws or the like. Bracket members 44, 46 and pins 48, 50 are formed of a material of suitable strength such as, for example, steel. The pins 48, 5t) have a size and coniiguration slightly smaller than the inner dimensions o-f ferrules 28, such that they may be inserted in `a close fitting relationship in the ferrules to mount panel assembly 12 on post assembly 14. The other leg of each of the L-shaped bracket members 44, 46, is adjustably retained against the lip portion 40 of post members 36 as, `for example, by threaded members 52 and nuts 54. In this manner, L-shaped 4brackets 44 and 46 are adjustably connected with post members 36 such that their relative position along the length of members 36 may be adjusted to thereby adjust the position of panel assembly 12 along the length of post assembly 14.
In an upper portion of post 36, above the upper bracket 44 (as viewed in FIGf l), a channeled insert member S6 yformed of a suitably light and inexpensive material such as wood and having a generally U-shaped cross sectional conguration, is mounted in channel 38. As best seen in FIG. 3, the lower portion of member S6 rests on tongue 24 of panel assembly 12 when the wall structure is -in the assembled form. Insert member 56 is retained in channel 33 by the lips 40 and the apex wall of post member 36. In addition, insert member 56 ls retained in channel 38 at its lower end (as viewed in FIG. l) fby an abutting end of member 3i) and at its yupper end by a cap 62 `which is frictionally held on ythe upper' ends `of posts 36. Member 56 provides a channel or slot 5S for receiving a peripheral portion of panel member 60 which may, for example, be translucent, transparent, opaque or colored, as desired and formed of glass, plastic or glass fiber material sold under the trademark Fiberglass, or other suitable material.l The bottom portion of panel member 60 (as viewed in FIG. 1) is received within channel 32 in member 30. In the embodiment,'shown in FIGS. 1, 3 and 4, panel mem-ber 6i) is corrugated to provide additional strength.
A supporting foot 64 is adjustably mounted on the lower portion of post 36 by suitable fasteners such as, for example, screw 466 and a nut (not shown). This provides a means for adjusting the relative height of 'post lassembly 14, since member 64 is adjustable in its position along the length of post 34.
A modiiied form of the post assembly 14 is shown in FIG. 5a and generally indicated by reference numeral 14g. Assembly 14g includes a modified support foot 64a which may be used interchangeably with foot 64 `but is preferably used Where added rigidity is desired as, for example, on the end post of a wall structure. Foot 64a includes a pair of toe-like projections 6? extending outwardly from the bottom of foot 64a in a direction transverse to the direction in which the panel assembly 12 extends from the post assembly. The toes 68 include apertures 72 through which suitable fasteners such as bolts, screws, or the like, may be inserted to attach foot 64a and hence the wall structure to a oor surface. Foot 64a is adjustably mounted to post members 36 similarly to foot 64 by fastener 66.
In FIGS. 6-11 are shown several alternate `forms of the post assembly 14 which may be used depending upon whether the post assembly is at the end of a wall structure or at the joint 'between two or more panel units in a wa-ll structure. Th'us, the post assembly 14a shown in FIG. 6 and the assembly 141 shown in FIIG. 11 are designed for use when the post assembly is at the end of a wall structure. As shown in FIG. 6, post assem-bly 14a includes a U-shaped post 36a whose periphery forms generally a square in cross section of substantially the same size as the pair of posts 36 shown in FIG. 4. Post 36a includes a channel 38a and lips 40a for receiving and retaining an insert member 50a having a channel 58a which receives a panel member 60a. Panel member 66a, in the embodiments shown in FIGS. 6-11, has a planar, non-corrugated form. As shown in FIG. 6, the exterior of the apex wall of post 36a forms an attractive end of regular conguration to the wall structure in whi-ch it is employed.
Referring now to FIG. 7, a post assembly generally indicated by reference numeral 14b, is shown which is designed for use as the corner post at the junction of two panel units in a wall structure. Post assembly 14b includes a post 36a, insert member 56a and panel memlber 60a of the type shown in FIG. 6. In addition, post 36 is secured to post 36a in the Imanner described in connection with posts 36 in FIGS. 4 and 5. An insert 5611 having -a channel or slot 5311 for receiving panel member 60a is retained in channel 38 by lips 40.
In FIG. 8, there is shown an assembly 14e which includes posts 36, inserts 50b, and panel 60a arranged to provide a post assembly for use at the junction o f four panel units. Assembly 14d, useful for the junctionof three panel uni/ts, includes the structure shown in assembly 14h plus an additional post 36 insertV 58h and panel 60a arranged in or opposite side of post 36a; Assembly 14e which may .also be used at a junction of three panel units includes the structure of1 assembly 14C' with post 36 omitted. Assembly 14j, shown in FIG; ll, is ruseful as an alternate form of end post which may easily be converted to an assembly as shown in FIG; 4. In assembly 14j, one of two posts 36 includes a cover strip 80 havin-g spring ngers -82 bearing against lips 40 to retain cover strip ti in the channel side of post 36. The other post includes a channel insert 56b and panel 60a arranged as in 7; Y i l Assembly of the wall structure 10 is accomplished as follows: A post 36 of the type shown in FIG. 6 o r, alternatively, FIG. 1l, is selected as one end of a wall structure. yBrackets 46 and 48 are mounted in channel 42 and adjusted to the height desired depending on the space desired between the iloor and the bottom of panel assembly 12 and the height desired for panel 460. The post assembly 14 is then set up by securing shoe 64a to the Hoor. The height of the assembly is set by adjusting assembly 14g in shoe 64a.
A second post 36 having brackets 46 and 43 secured thereto is then selected and a panel assembly 12 is attached thereto to form a panel unit. This is accomplished by inserting tongues 24 and 25 into the channel 42 to align the panel assembly with the post 34. When the tongues are fully inserted, pins 48 and 50 will be aligned with receptacles 26 and 27, respectively, and the assembly 12 may be lowered to the mounted position shown in FIGS. 1 and 3. The panel unit is then connected to the end post in the manner described in connection with forming the panel unit. Thereafter, the appropriate insert members S8 (or 58a or Sb) are selected and placed in channels 56 (or 56a or 56h) and a panel member 60 or 60a is placed therein. Finally, the cap 62 is placed on posts 36. It will be seen that by the proper selection of the assemblies, shown in FIGS. 4 and 6-11, the desired arrangement for a cubicle or room divider 10 is provided.
