Referring first to FIGS. 14, there is shown a cabinet C embodying the invention. This cabinet has a rectangular frame structure F best shown in FIGS. 38, to which reference will be made later. The cabinet has a horizontal rectangular top 11, lateral side walls 12a, 12b, and a vertical rear wall 14. A vertical front door 15 is carried on a long hinge 16. The cabinet stands on four legs 18 located at the corners of the cabinet. Inside the cabinet is a slidable shelf 19. A drawer 20 is also slidably mounted in the cabinet. The front end wall 21 of the drawer is exposed below door 15. The door has a handle 22 for opening and closing, and a catch 23 for holding it closed. The drawer has knob 24 on its front wall 21.

The frame structure F of the cabinet as shown in FIGS. 3-8, includes eight corner assemblies 25 each formed by two

angle bars

26, 27. A flat right-angle bridge plate 28 is placed on the horizontal

parallel walls

29, 30 of

bars

26, 27. Screws 32 in holes 31 of the plate secure the bridge plate 28 to threaded holes 31' in

walls

29, 30.

Abutting edges

33, 34 of

vertical walls

36, 37 of the angle bars are beveled; see FIG. 7. Four vertical posts 40 are connected to the respective corner assemblies. Each of the posts is in the form of an angle bar with ends of the angle bar displaced to form flat flanges 45 which abut inner adjacent ends of

vertical walls

36, 37. Screws 46 are inserted through holes 47 in the flanges and are screwed into threaded holes 48 in the ends of

walls

36, 37. Ledges 49 are formed at the inner ends of flanges 45 where they are bent inwardly of walls 50, 52 of the posts. These ledges seat on horizontal edges of

walls

36, 37 of the angle bars 26, 27. A rectangular notch 39 in wall 30 receives the adjacent end of wall 29 in a flat coplanar arrangement at each corner assembly 25.

Four horizontal cross members are provided at the bottom of the frame F as shown in FIGS. 3, 4 and 5. These cross members are angle bars with inwardly displaced flat flanges 56 at opposite ends of the walls '57, 59 of the angle bars. Flanges 56 are juxtaposed to ends of

walls

36, 37 of the corner angle bars and are secured by screws 5'8 screwed into threaded holes 60 in outer ends of

walls

36, 37. The screws 58 pass through holes 6 1 in flanges 56. Four horizontal cross members 55' are provided at the upper end of the frame to complete the rectangular frame structure. It will be noted that ledges 62 are formed at the inner ends of the flanges 56 to form seats which abut outer ends of

walls

36, 37. The walls 50, 52 of posts '40 and the walls 5-7, 59 of cross members 55 and '55 are all flush with or coplanar with

walls

36, 37 of the corner assemblies. The corner plates 28 reinforce and stiffen the corner structures.

In order to support sliding shelves or drawers in the cabinet C, there is provided a pair of horizontal cross members 70a, 70b; see FIGS. 3-6. These cross members are angle bars whose vertical walls 72 are secured by screws at their ends to vertical side walls of the posts 40.

On the horizontal walls 74 of the cross members 70a, 70b are mounted drawer. or shelf guide assemblies 75 best shown in FIGS. 6, 911. has a short rectangular tube 76 which is axially horizontal. Two laterally extending flat arms 78 are welded near opposite endsof (the underside of .the tube. Outer ends of the arms have holes 79 which receive screws 81.

Holes 7-9 register with corresponding holes in the walls 74 of the cross members in which the screws 81 are screwed. The tubes 76 are thus supported laterally of the cross members 70a, 70b atopposite sides of the frame Each guide assembly 75 F. Two other guide assemblies 75 identical to guide assemblies 75 aresecured to horizontal walls 59 of bottom cross members 55 at the sides of the frame F.

The upper guide assemblies 75 support horizontal shelfv 19 and the lower guide assemblies 75 support drawer 20. The shelf and drawer can be interchanged in position.

Alternatively, two shelves or two drawers can be provided in the frame. In order to mount the shelf and drawer on the tubes 76, there are provided long rectangular tubularsliders 92 forming parts of the guide assemblies. Each slider 92, as best shown in FIG. 9, has a bracket plate 93 at its front end. The bracket has an apertured plate or flange portion 94 offset from the slider 92.. .Flange 94 is secured by screws 90 to the underside 19 or 20' of the shelf 19 or drawer '20. The slider 92 extends axially through the tube 76.. The tube has a pair of horizontal cylindrical rods. or rollers 95 at each end thereof; see FIGS. 9-ll. The rods extend through holes 9 6 in the side walls 97-of tube. 76. Cotter'pins or other. locking means 97 at ends of the rods hold the rods in they tube. The rods in each pair are located near upper and lower

horizontal walls

98, 99 of the tube 7 6 so that the slider 92 is supported only by the rods and is out of contactwith the upper and lower walls 98, '99 of the tube. As the sliders '92 move axially in one direction or the other through tube 76, the rods 95 may rotate like rollers to facilitate sliding movement of the sliders. Thus the shelf 19 and drawer 29 are pulledout and pushed in easily without binding, as the sliders 92 move in tubes 76.

The rear ends of the sliders 92 carry angle brackets 100 whose upper ofiset flanges 102 are apertured for receiv- From the vertical flanges 103 The upper surfaces of bracket plates 93' and flanges 102 need extend only slightly, about one sixteenth of an inch or so above the upper sides of tubes 76 so that the bottom of the drawer of shelf clears the tubes.

It will be apparent that the cabinet C can be quickly assembled without requiring any particular skill on the a part of the assembler. The parts of the cabinet are all pre-cut and prefabricated in proper lengths. The cabinet can be shipped knocked-down for assembly at the place whereit is to be used. The several walls and panels of the cabinet canbe made of any desired mate-.

rials such as wood, metal, plastic, laminated plastic on wood, etc. The corner assemblies made of prefabricated parts are quickly put together. The several parts of the frame F .can be made of metal, wood or plastic.

Horizontal walls 29' and 30' of the angle bars 26', 37' have beveled inner adjacent ends 29a, 30a to provide a flush corner structure. The inner adjacent ends 33, 34 of.

vertical walls

36, 37 are beveled as in corner assembly 25. The post 40 fits snugly on the corner. assembly with offset end flanges 45 secured to inner adjacent ends of vertical walls 37. -A pair of flat cross plates 28a, 28b are provided for strengthening the corner structure. These plates have holes 31a and 31b which are aligned with holes 31c in the horizontal. walls 29., 30'. The aligned holes receive screws 32a. The holes 31a and 31c can be unthreaded and holes 31b may be threaded for engaging the threads of the screws. The two plates 28a, 28b are juxtaposed to opposite sides of walls 29', 30' ,to form a very rigid corner structure.

FIG. 14'Sh0WS another corner assembly 25b whichv is similar to thecorner assembly 25 except that the end of post 40 fits inside .the corner wallsf36, 37 and is offset from the outer sides of

walls

Rear ends of the. sliders may be threaded at 153 and may be engaged in threaded holes The sliders 92awill support the drawer 20a in a-horizontal position so that it can easily be pulled out-of cabinet, C or pushed .into the cabinet. The end blocks 150' will serve as stop 154 formed in front faces of the blocks.

members to prevent the drawer from being pulled com pletely out of the cabinet since the blocks will be stopped at the rear ends of the tubes 76a. Other partscorresponding .to those of cabinet C numbered.

FIGS. 22 and 23 show an extruded post which can be used in assembling a cabinet, This post hasa rectangular body 162. Two flatparallel flanges 163 extend laterally outward of one side to define a groove 164 into which a panel can be inserted. Another pair of flat parallel flanges 167 extend laterally outward of an adjacent side of the post body to define a groove 168 for receiving another. panel.

other similar panel can be secured to the other end of the Each tube 76a has laterally extending arms 78' which support the tube in axially. horizontal position. The ends of the arms have holes 79' which receive "screws The screws are engaged in horizontal. walls 74' at These crossbars in turn have walls At thev and frame F are identically.

post. The posts 160 can beused to make up a cabinet frame quickly and inexpensively, and the cabinet can be quickly completed by inserting the panels in the post. The posts can be secured to any of the prefabricated corner assemblies 25, 25a-25c described above. The shelf and drawer mounting assemblies 75 or 75a can be mounted on posts 160 in the same manner as explained and illustrated in connection with frames F and F.

It is also possible to assemble a cabinet using frames 125 and panels 131 with corner posts 160 as illustrated in FIG. 23. The slats 126 of frames 125 and an end of each cross or brace plate 127 will fit into the

grooves

164 and 168 along with edges of panels 131.

FIGS. 24-26 show another drawer mounting assembly for a cabinet in which parts corresponding to those of cabinet CC in which parts corresponding to those of cabinet C are identically numbered. The drawer 20b is a molded plastic unit made of polyethylene, vinyl or the like. It has lateral flanges 180 at upper edges of its side walls 182. These flanges fit slidably into two horizontal channel bars 184 and 185 supported by angle brackets 186 at inner sides of the side walls 12a, 12b. The-angle brackets have apertured flanges 192 secured by flathead bolts 188 and nuts 189 to the vertical posts 40 at opposite ends of the channel bars 184, 185. The channel bars are secured at their ends by flathead bolts 190 and nuts 191 to apertured flanges 193 of the brackets. By this arrangement the drawer slides freely in and out of the cabinet. The drawer can be removed entirely from the cabinet. For a permanent non-removable drawer mounting the arrangement of drawer with sliders .92 may be used.

There has thus been described a novel cabinet frame construction with prefabricated corner assemblies and with prefabricated drawer and shelf slides. Instead of a single door 15 mounted on a single hinge 16 to a single post 40, two doors can be provided mounted on adjacent front posts 40 for making a wider cabinet. If desired, the

drawers

20, 20a, 2% can be wholly concealed inside the cabinet by making the door or doors 15 longer to cover the front ends of the drawers.

While I have illustrated and described the preferred embodiments of my invention, it is to be understood that I do not limit myself to the precise constructions herein disclosed and that various changes and modifications may be made within the scope of the invention as defined in the appended claims.
