14770NEX5 CONSTRUCTION UNIT Gustav Warner Hult, Euclid, Ohio, assignor to The Mills Company, Cleveland, Ohio, a corporation of Ohio Application August 4, 1953, Serial No. 372,230 13 Claims. (Cl. 189--34) details of a supporting bracket used with the present invention; and

Fig. 8 is an enlarged fragmentary sectional view of one of the doors of the cubicle assembly showing a modified form of panel construction contemplated by the present invention.

Cubicle assemblies embodying the present invention may be of various types for use in various places and are particularly suitable for use in toilet rooms and the like.

Referring to the drawings the cubicle assembly embodying the present invention is shown located in the corner of a room having permanent walls 10 and 11 forming two sides of the assembly. The assembly comprises two individual cubicles 12 and 13 formed by

pilasters

15, 16, 17 floor mounted along a line perpendicular to wall 10 and. defining door openings into vision of a new and improved cubicle assembly comprised .of novel sheet metal panel members and means for supporting and securing the panels in their assembled relationship, the sides of the panels being formed by spaced, opposed metal sheets having overlapping, interlocking marginal flanges so shaped and arranged that the sheets can be quickly and easily assembled and when assembled are securely held in their proper position and have a pleasing appearance free from unsightly lines and offsets.

Another object of the present invention is the pro vision of a new and improved metal panel construction comprising spaced, opposed metal sheets forming the sides of the panel, the sheets having overlying, interlocking marginal flanges for locking the sheets together, which flanges are so constructed as to present a pleasing appearance free from objectionable offsets and unsightly lines, and to eliminate objectionable gaps caused bysepa: ration of the sheets with use. i

A further object of the present invention is the provision of a sheet metal panel comprised of two sheet metal sections which are easily fabricated, quickly as: sembled, and which when assembled are securely held in their proper position by the interlocking; action of marginal flanges on each sheet which abut against a surface or shoulder on the other sheet.

the cubicles, and

side walls

20, 21 extending from the

pilasters

16, 17 respectively to the wall 11 to provide side walls for the individual cubicles. The pilasters are each connected at their upper ends to a sheet metal head rail 22 extending from the wall 10 to the pilaster 17. A

rail 23 also extends from the upper end of pilaster 17 to the room wall 11.

The cubicles 12, 13 are provided with doors 24, 25'

respectively hinged to the vertical edge of the'left hand pilaster defining the door opening into each cubicle. Each The invention resides in certain constructions and corn binations and arrangements of parts and further objects and advantages of the invention will be apparent to those skilled in the art to which it relates from the following description of the preferred embodiment described with reference to the accompanying drawing forming a part of this specification and in which: 7

Fig. 1 is a perspective view of a cubicle assembly em,- bodying the present invention;

Fig. 2 is a sectional view taken approximately along line 2-2 of Fig. 1;

Fig. 3 is a fragmentary enlarged view of one of the pilasters of the cubicle assembly;

Fig. 4 is a vertical sectional view taken approximately along line 44 of Fig. 3;

Fig. 5 is an enlarged fragmentary vertical sectional view of one of the doors of the cubicle assembly;

Fig. 6 is an enlarged sectional view taken approximately along'line 66 of Fig. 1;

Fig. 7 is an enlarged fragmentary view showing the door is provided with fittings 26 attached thereto at the top and bottom of the door respectively adjacent the left hand edge thereof, which fittings are adapted to re-' ceive the "hinge pins 27 of hinge stocks 28 mounted on the left hand pilaster of the door opening. The fittings 26 are shaped so as to fit over the door edge. The hinge stocks 28 are of conventional construction and are preferably of the spring-biased type. Inasmuch as such hinges are commercially available, their construction will not be described in detail. The lower hinge pins, however, are preferably rectangular while the upper ones are preferably round.

The

doors

24, 25 are each formed of two opposed, spaced

metal sheets

30, 31 having

marginal flanges

32, 33 respectively along and substantially coextensive with their horizontal and vertical edges. The sheet 30 forms the inner face of the door while the sheet 31 forms the and constituting the outside overlapping flange. The

flanges areso shaped as to cooperate with each other to lock the

sheets

30, 31 in their proper relationship. As shown each flange is reversel y bent to form .a shoulder 34 immediately adjacent and parallel to its inner edge, the outer or projecting portion of the flange, here inafter referred to as the convex portion, being curved outwardly to form a portion arcuate in cross-section adapted to cooperate with the corresponding flange on the other sheet to interlock the sheets in their proper position. The convex portion-s 35, 36 of

flanges

32, 33, respectively, are proportioned so that the outer edge of the outside flange 33 abuts the shoulder '34 on the corresponding inside or overlapped flange 32 of the sheet 30 when the edge of portion 35 of the corresponding inside marginal flange 32 on sheet 30 abuts the inside surface of the sheet 31. It can now be seen that the sheets will be prevented by the engagement of flange.

radius of curvature of the inside surface of portion 36 is approximately equal to the radius of curvature of the outside surface of portion 35. It will be noted that the thickness of the sheet 31 is slightly less than the height of the shoulder 34 so that the edge of the overlying or overlapping flange 33 does not present any visible offset appearing merely as a line extending along the edge portions corresponding to the line presented by the base of shoulder 34 on the same flange. In addition, the panel viewed in elevation from either side appears as a flat surface and this will be true even if the edge of flange 33 separates from the shoulder 34 since the height of the shoulder or the height of the convex portion, depending on which side is being viewed, will hide the gap from the observer.

The door panel may be quickly and easily fabricated from a sheet metal blank. Prior to assembling the metal sheets 30 and 31 a piece of laminated fiberboard 37 is inserted therebetween to deaden the noise producing qualities of the panel member and to increase the fire resistance of the member. The panel member may have portions of the marginal flanges cut out to accommodate fittings 26.

The panel

members forming pilasters

15, 16, 17, are formed by opposed spaced metal sheets having vertical edges with overlapping

marginal edges

38, 39 similar to

flanges

32, 33, respectively, of the door panels. The horizontal edges of the pilasters are not provided with marginal flanges which interlock since the pilasters are secured at the top and bottom, respectively, to the head rail 22 and the floor. The fiberboard between the sheet metal sections forming each pilaster terminates at a point below the top of the pilaster allowing the head rail 22 to be inserted between the inner and outer faces thereof as is illustrated in Fig. 4. The pilaster may be secured to the head rail by suitable metal screws.

The fiberboard intermediate the metal sheets forming the pilaster also terminates short of the bottom of the pilaster to allow a metal frame member 40 to be inserted therein for purposes of fastening the pilaster to the floor of the room. The metal frame member is U-shaped in cross section, is fabricated from sheet metal, and is adapted to have its sides secured to the inner surfaces of the metal sheets forming the pilaster by metal screws. The bottom of the U-shaped frame member is adapted to be mounted flush with the floor of the room and to be secured thereto by anchor bolts in a manner well-known in the art. The bottom of each pilaster is covered by a sheet metal shoe 41 which may slide upwardly on the pilaster.

The pilaster 15 which forms the extreme left hand pilaster of the cubicle assembly is connected to the wall by wall brackets 42 having spaced arms 43 extending outwardly from the wall to receive the pilaster therebetween. The pilaster 15 is secured to the wall brackets by metal screws so that the left hand vertical edge of the pilaster is spaced from, and parallel to, the wall 10.

Sheet metal panels similar to the metal panels which form the

doors

24, 25 are utilized to provide

side walls

20, 21 of the cubicles 12, 13. The side walls do not have marginal interlocking flanges along their vertical edges but rather are provided with flanges which are bent inwardly at right angles toward each other to present a flat panel edge which is adapted to abut a plane surface as shown in Figs. 1 and 2. The horizontal edges, however, are provided with overlapping, interlocking marginal flanges as shown in Fig. 6 which are similar to, and cooperate in the same manner as the

flanges

32, 33 of the

metal sheets

30, 31 forming the door panel. The

side walls

20, 21, are each secured to their

respective pilasters

16, 17, by L-shaped brackets 44 having

legs

45, 46. The leg 45 is U-shaped in cross section and adapted to fit over the panel edge while the leg 46 is adapted to be secured to the flat inner side of the pilaster to which the side wall is connected. The side walls are provided with two such brackets, one engaging and supporting the lower panel edge and the other engaging the top panel edge. The structure of the brackets 44 enables the side walls to be readily connected to, or disconnected from, the pilasters of the assembly. The side walls are connected at their rearward vertical edge to the room wall 11 and spaced therefrom by brackets 47 which are similar in construction to the brackets which secure the pilaster 15 to the wall 10.

The doors 25 on the respective cubicles are adapted to swing inwardly or outwardly according to the available space. The direction in which the door-s swing is determined by the position of a door bumper against which the door abuts when it is in its closed position. The door on cubicle 12 is illustrated as swinging outwardly and is provided with a bumper 50 mounted on pilaster 16 so as to engage the inner side of the door 25 when in closed position. The bumper is in line with the inner side of pilaster 16 and extends from the left hand edge thereof into the door opening. The position of the bumper 50 is such that when the door is in abutting engagement with the bumper the door is substantially in line with the

pilasters

15 and 16.

A side latch 51 having a latching lever 52 is mounted on the inside face of the door to enable the door to be locked from the inside. The latching lever 52 is adapted to be moved laterally to engage the outer side of the bumper 50 and prevent the door from swinging outwardly. A plastic handle 53 may be mounted on the outside face of the door to provide a means for opening the closed door.

The door in cubicle 13 is illustrated as swinging inwardly and in this case a door bumper 55 is mounted on the pilaster 17 so as to engage the outside right hand edge of the door when the door is in its closed position. The bumper 55 is supported by a stirrup bracket 56 having a portion 57 extending toward the inner part of the cubicle and adapted to engage the latching lever 58 of a side latch 59 mounted on the interior face of the door similar to the side latch 51. It can be seen that the bumper 55 while preventing outward movement of the door allows the door to be swung inwardly permitting access to the cubicle.

A modified form of panel construction is illustrated in Fig. 8. The modified panel comprises two opposed spaced

metal sheets

60, 61 having marginal flanges 62, 63, respectively, extending inwardly toward the other sheet. The flanges 62, 63 are each reversely bent to provide a shoulder 64 extending the length of the flange adjacent its inner edge. The outer portion of each flange is convex, the radius of curvature of the inside surface of the flange 62 being substantially the same as the radius of curvature of the outside of flange 63. The flanges 62, 63 are of substantially the same width and when the

opposed sheets

60, 61 are in their assembled position as illustrated in Fig. 8, the edge of flange 62 abuts the shoulder 64 on the corresponding flange 63 and the edge of flange 63 terminates short of the inside surface of the sheet 60. The engagement of the flange 62 with the shoulder 64 will prevent inward displacement of the two sheets. As in the first described embodiment, the arcuate portions of the corresponding flanges cooperate to prevent the sheets from being separated. It will be noted that externally the modified panel will have the same pleasing appearance as the first described embodiment. The modified panel may have marginal flanges along both the vertical and horizontal sides, or the flanges may be omitted from either the horizontal or vertical sides in order to form pilasters and side walls as previously described.

It can now be seen that I have provided an improved cubicle assembly having panel members of novel construction and improved means for holding and securing the panels in their assembled relationship.

It is apparent that the invention is susceptible to various modifications within the scope of the appended claims and is not limited to the particular construction described and anemone itis the intention to hereby cover all adaptations,-. modifications and variations which come within the practice of those skilled. in-- the art to-which the invention appertains.
