Claims.

This invention relates to shower cabinets and more particularly to an improved shower cabinet formed from a few separable and interchangeable parts and. sections which can be shipped to the place of use in knockdown condition and assembled at the place of use by unskilled labor and with a minimum of eiiort.

In accordance with this invention, an improved metal shower cabinet is presented, which can be made from sheet metal, which is sturdy and 1 strong in construction, highly attractive in design and appearance, and which can be made with a minimum of operations and at minimum cost.

Another object of this invention is to provide an improved shower cabinet so constructed that it may be assembled at the plant from a minimum number of parts and which may be interchangeably assembled in the field by unskilled labor to suit field conditions without special fittings or screws.

Still another object of this invention is to provide an improved shower cabinet formed into sections or units at the plant from a minimum number of parts, which sections or units may be interchangeably assembled, telescoped and snapped together in the field.

Other objects of this invention will become apparent as the disclosure proceeds.

Various other features and advantages of the,

invention will be apparent from the following particular description and from an inspection of the accompanying drawings.

Although the novel features which are believed to be characteristic of this invention will be particularly pointed out in the claims appended hereto, the invention itself, as to its objects and advantages, and the manner in which it may be carried out, may be better understood by referring to the following description taken in connection with the accompanying drawings forming a part thereof, in which:

Similar reference characters refer to similar parts throughout the several views of the drawings and the specification. 1

Referring to the drawings, this shower cabine comprises a base unit I, interchangeable side wall sections 2 and 3, a rear wall section 4, a top frame member 5 and a curtain hanger 6, which are rigidly assembled at the plant as individual units ready for quick erection in the field.

The base unit I is formed from only three main.

pieces of sheet metal formed to provide a pan member In supported upona base frame 20 and an intermediate frame 26. The base frame 20 is formed from a single elongated strip of sheet metal of suitable gauge which is bent into generally channel-shaped form, as shown in Figs. 2,

-31 and 5. This channel-shaped sheet'metal strip comprises essentially a side wall forming portion 2| which constitutes the bottom of the channel, an inturned flange 22 which is to rest on the floor of the building in which the cabinet is installed, and an inturned flange 23 upon which the pan l0 seats. The flange portion 22 may be provided with an upturned lip 24 to stiffen and strengthen the base frame. After the channel section 20 has been formed, it is bent to provide a rectangular frame by cutting V-shaped notches in the flanges 22 and 23 of the channel at the corners of the frame to provide a mitered joint secured by welding. The meeting ends of the channel-shaped section when bent into rectangular form are also welded together to provide a sturdy and rigid frame.

The pan member In is also formed from a single piece of sheet metal comprising a sloping bottom wall 30 which is defined by four sloped triangular shaped bottom wall portions 31 defined by radiating crease lines which radiate from a central drain aperture 38. The inner ends of the triangular shaped portions 31 may be depressed so as to present a generally depressed circular flange 39 to provide a seat for a suitable drain cover. The periphery of the bottom wall terminates in upturned vertical wall portions which form the front wall ll, side walls l2 and I4, and rear wall I 3 of the base unit. The free ends of these vertical walls are suitably welded together at the corners. The inturned flange 23 of the base frame 20 is secured as by spot welding 36 to the bottom wall 30 of the pan adjacent the periphery'thereof. The side wall forming front wall ll, side walls l2 and i4, and rear wall l3 of the base unit.

The bottom wall of the pan member is reting V notches in the intumed flange 23, the adjacent edges of the V cuts being secured together as by welding. The ends of the leg portion 21 3 of the 1 frame when bent into rectangular form are secured together. as, by welding, The outi turned flange 26 of the frame26is'secured to the bottomwalljll of the pan member asby spot f welds 26'. The frame 26 is so shaped that the I intumed flange 23 thereof will rest upon the floor 1 upon which the cabinet is supported.

The side wall sections 2 and 3 are each fornied from ;a. single piece of sheet metal and when formed areidenticalin shape. ,Each of the side 1 wallsections'2 and} comprises a sidewall panel 3| and an intumed panel portion 32 at each end 1 thereof, Each' intumed panel :portion 32 has its 1 free edge shaped into tube formation 32" -com-, 1 prising an edge portion 33 bent at right angles a to panel portion,- a rebent .p ortion 34 extends ing generally parallel tothepanel portion 32,

and an intumed lip portion 35 extending in-. 'wardly toward the adjacent, panel portion 32. 1 Each side wall section. is thus provided with two panel portions 32 having their free side edges bentinto tube formation. 32' so that either panel portion 32 may be positioned to form a partof therear wall of the cabinet or part of the front wall of the cabinet.

One of the side wall sections 2 is provided with a pair of spaced apertures 90 through which hot 5 and .cold water control fixtures 9| extend. It will be appreciated that the water control fixtures 9| are suitably connected to hot and cold water piping outside of the side wall section 2 of the cabinet. Side wall section 2 is also provided with an opening 92 adjacent the top thereof through which a portion of the spray head fixture 93 extends, which is also connected to j the water supply pipe.

that since the side wall sections 2 and 3 are iden- 1 tical in form, the side wall section 2 carrying the water fixture openings may be positioned on either the right hand side or left hand side of It will be appreciated the cabinet, to suit field conditions.

The rear wall section 4 comprises a relatively flat rear panel 4| which is the same height as the 1 side wall sections 2 and 3 and which is of a width sumcient to fit snugly between the intumed side 1 portions 33 of the adjacent side wall sections. Each side edge of the rear wall panel 4| is proj vided with an intumed portion 42 designed to snugly overlie the side portion 33 of the adjacent side wall section, an outturned portion 43 designedto snugly overlie the edge portion 34 of 1 the side wall section, and a'rebent lip portion 44 I which extends at an acute angle with respect to 1 portion 43 so a to frictionally grip the intumed lip portion 35 of the adjacent side wall section. It will be appreciated that by bending ,the lip I portion 2| or frame 20 is arranged. so j that its outside su'iface is substantially in alignment with the outside surface of the adjacent portion 44 at an acute angle with respect to the portion 43, this lip portion resiliently grips the adjacent lip portion 35 of the side wall section so as to frictionally but rigidly retain the rear panel section 4 in fixed upright position. In the construction here provided no screws or other securing means are needed to secure the rear wall section 4 to the adjacent side wall sections 2-fand 3. A saving in material and substantially greater speed of erection and demolition are thus realized. 1

1 The rear wall section 4 and each of the side wall sections 2 and 3 are provided with, spaced angle-shaped clips 56 at the lower end thereof, which are: secured thereto at spaced intervals.

I Each ofthese' clipscomprises a relatively fiat leg portion 51 secured to the adjacent side wall or rear wall section'as by spot welds 58, an offset portion 59, a downturned leg portion 60, and an outwardly flared lip portion 6|. Each of the vertical walls It, I 2,13 and I4 of the .base unit carries an angle-shaped bar 60 on the inside face thereof with which the clips 56 are arrangedto interlock to detachablyisecure the side and rear wall sections in rigid vertically extending position. Each angle-shaped bar-'50. comprises -a downtumedileg. 5| which is. securedfto, the adjacentvertical wall offthebase unit as.-by spot welds 52, an intumed hip portion 53, and. an upturned leg portion 54 whichflis so shaped as tosnuglyLseat against the outside face of the adjacent side ,or, rear walisection. .The upwardly extending leg 64 seats within a pocket 55 defined between the downturned leg portion '60 of the clip 66 and theadjacent outside face of the side or rear wall section. The. .clip 56 are formed from sheet metal, generally referred to asv Z-bar in form, ind' may be of almost any length from one inch to-substantially' the width of the side and rearwall section across which it extends. While the bar 5|] preferably extends along substantially the entire-vertical wail of the pan, it also may be 'cut into spaced sections, if desired. v a V a When erected, the-lower edges of the side wall sections 2 and 3 and rear wall section 4 are designed to seat snugly against'the inside face of the bottom wall 30 of the pan Hi and are held in spaced relationship from the adjacent vertical walls ll, l2, l3 and I4 of the base unit, which vertical walls are each provided with-a generally rounded intumed flange portion I5 which has a free edge l6 which abuts the outside face of the adjacent side or rear wall section. Thus the side wall sections 2 and 3 and the rear wall section 4 are rigidly braced and held in fixed erect position by the bracing action of the edges I6 as well as by the bars 50 interlocking with the clips 56. The intumed flange portion l5 forms with the adjacent vertical walls ll, l2, l3- and I4 and the adjacent side and rear wall sections an enclosed housing 62 within which the locking bars 50 and the locking clips 56 are housed and contained. The rounded flange portion l5 of the vertical walls ,I I, l2, l3 and M of the base unit gives the cabinet an attractive and decorative contour which measurably adds to its finished appearance.

The front wall I l of the base unit, as shown more particularly in Figs. 1, 2 and 3, is provided with an intumed tread portion l8 which is formed integral therewith and which extends between the inturned side portions 33 which define the entrance opening into the cabinet. The tread portion 3 extends a convenient distance inwardly so as to provide a smooth and comfortable foot tread. The ends I8 of the tread portion I3 are so cut and formed as to snugly abut the inturned edge portions 33 of the adjacent side wall sections so as to firmly brace the side wall sections at the lower end thereof against inward movement. The tread portion I8 is pro-" vided with a downturned flange portion I9 which terminates in an outturned lip portion III, which further strengthens and stiffens the tread portion and gives the interior of the cabinet a finished appearance, free from raw edges which might otherwise cause injury to the occupant.

The top edges of the sidewall sections 2 and 3 and rear wall section 4 are enclosed withina rectangular shaped head frame 5 which is formed from a single piece of sheet metal of a generally channel shape in cross-section. The sheet metal strip from which the head frame 5 is formed is first bent into the cross-section generally illustrated in Figs. 1 and 3 comprising generally a downturned leg portion III, a top flange portion II bent at right angles to the leg portion II, and a rounded embracing flange portion 12. The flange portion II and the rounded flange portion 12 are provided with V notches which permit the shaped strip to be bent into rectangular form, the free edges adjacent the notches being secured together as by welding. The free ends of the leg portion III of the strip are also seecured together by welding so as to provide a rigid rectangular-shaped head frame. It will be noted by referring more particularly to Fig. 3 that the inner edge 13 of the rounded flange portion I2 of the head frame is arranged to abut against adjacent faces of the side and rear wall sections, so that these sections are held in rigid rectangular alignment. The leg portion I is also so arranged as to generally align with the vertical walls II, I 2, I3 and I4 of the base unit positioned therebelow so as to produce a symmetrical arrangement of the parts, free from protruding raw edges, providing a framed appearance for the lower and upper ends of the cabinet having a rounded and attractive symmetry.

To prevent movement of the upper end of the side wall sections withinthe head frame 5, the flange portion II preferably terminates in a downturned lip I4 which is so spaced as to snugly engage the inside face of the portions 43 of the rear wall section 4 and the portions 34 of the side wall sections adjacent the entrance way to the cabinet. The downturned lip portion I4, formed as an integral part of the head frame 5, rigidifies the head frame construction and provides means to prevent in-bowing of the side and rear wall sections. If further means are desired to hold the frame in position, paired tongue portions 15 may be struck out from the inturned flange portion ll of the head frame. The paired downwardly extending tongues 15 are so positioned and arranged as to snugly fit within the interior of the tube formations 32' formed at the free edges of the panel portions 32 of each side wall section. The downwardly extending paired tongues I provide abutments which further prevent inward movement of the side wall sections 2 and 3 and provide means for frictionally retaining the head frame 5 in its telescoped position over the side wall sections and the rear wall section of the cabinet. As further or alternate securing means, tongues 16 may be struck out from the inturned flange portion II at spaced intervals so as to abut against the inside face of the wall forming panels 3| of the side wall sections 2 and 3, the wall forming panel 4| of the rear wall section and the wall forming panel 32 of the side wall sections.

It will be appreciated that under normal conditions the downturned lip portion I4 may be amply suflicient to hold the upper end of the side and rear wall sections in rigid rectangular alignment, but if this is not sufllcient the paired tongues 15 or the single tongues 16 or both may be used in conjunction therewith. If the downturned lip 14 is not used either the paired tongues I5 or the single tongues It or both may be selectively used as desired.,

A curtain rod Ii, which may be a solid rod or bar or a-hollow tube, is supported by suitable brackets 18 secured to the head frame. Each bracket 18 may be formed from a stamped piece of sheet metal comprising an outturned base portion I9 secured as by spot welds to the inturned top flange portion II of the head frame in a position to support the curtain rod 5 and the curtain depending therefrom in convenient position adjacent the entrance way into the cabinet. A leg portion extends downwardly from the base portion, 13 and, as shown more particularly in Fig. 2, is provided with a bayonet slot 8I which terminates in a depressed circular seat 82 within which the end of the rod 6 may rest. The curtain rod 6 is of such length as to extend between the side wall panels 3I of the side wall sections and may be quickly placed in supported position upon the paired brackets I8 when the cabinet has been erected.

It will be appreciated that a shower cabinet constructed in accordance with this invention may be quickly formed and assembled at the plant from relatively few parts formed into a few separate units or sections. The base pan I0 is formed from a single sheet of metal which can be quickly stamped and bent into the desired shape to form not only the bottom wall 30 of the base unit but the vertical walls II, I2, I3 and I4. The vertical walls where they extend djacent the side wall sections and the rear wall section of the cabinet are provided with a rounded inturned flange portion I5 formed by a simple stamping operation. The front wall II adjacent the entrance way is provided with a tread portion I8 integral therewith, shaped by a simple stamping operation. Heretofore the threshold tread has been formed as a separate piece of complicated construction and difficult to attach. The base frame 20 and the intermediate frame 26 are each shaped from a single strip of sheet metal and quickly secured as by spot welds to the bottom wall 30 of the pan. The locking bars 50 extending around the inside face of the vertical walls II, I2, I3 and I4 of the pan may also be quickly secured to these vertical walls by spot welds, completing the assembly of the base unit.

The side wall sections 2 and 3 are identical in shape and may be kept in stock. Either one of these sections may be provided with apertures and 92 to receive the piping fixtures, and they are so shaped as to permit interchangeable assembly in the field. The side wall sections 2 and 3 and the rear wall section 4 are each provided with a series of spaced clips 56 secured thereto as by spot welding and arranged to telescope over and securely interlock with the adjacent locking bars 50. The rear wall section 4 of the cabinet may be quickly snapped iJtO position between the adjacent panel portions 32 of the erected side wall sections 2 and 3. The head frame 5 is applied by telescoping the same over the side and rear wallsections with th n ue 15 in the tube formations}? cfthe side wan "sectionsso asto fixedly ,l ecure the head frame in position and prevent inward movement of theside wall sections: rod "hanger 6 is, then placed in pomtion, completing erection of the ;.clabinet. Plumbing connection to the water-piping and drain outletcan be convenient-' ly made dueto the interchangeability of the side wall sections} and 8.' r

It will be noted that the improved cabinet herein; disclosed can be quickly assembled and erected in the meld without theapplication of screws, fitting of the parts or other time-com suming erection'operations." The cabinet can be quickly dismantled for storage or erection at an-' of construction, and a highly attractive and symmetrical appearance. I

While certain novel features .of the invention have been'dis'closed and are pointed out in the annexed claims, it will be understood that various omissions, substitutions and-changes maybe made by those skilledin the art without departing from the spirit of the invention. 1
