Definitions

  • ABSTRACT A collapsible cabinet, preferably made of sheet metal, consists of a base, a top, rear wall, sidewalls, and a door frame.
  • the sidewalls are located relative to the base and top by projecting angle portions which fit around the corners of [51] rm.c
  • This invention relates to collapsible cabinets comprising a base, a top, a door frame, a rear wall, and sidewalls the longitudinal edges of which are arranged for interlocking engagement.
  • Such cabinets may be employed for many purposes. Their special advantage reside in that the cabinets may be carried to the place of assembly in the collapsed state, and need not be assembled until after arrival. Great saving can thereby be obtained on transport charges, since the very great amount of space required in comparison to weight in the case of hollow units, in no longer needed. Economical shipping over long distances, e.g. overseas is also becoming possible.
  • a collapsible cabinet comprising a base, a cover, a door frame and lateral sidewalls, the longitudinal edges of which are arranged for interlocking engagement, wherein the longitudinal edges are provided with portions bent over through approximately 180- to form hooks for interlocking engagement, two opposed sidewalls, a rear wall and an opposed door frame or two opposed door frames are provided with abutment angles arranged to enfiank the corner areas of the base and of the cover, and wherein horizontal bent over portions are provided on the sides and frames to determine the position of the base and cover'relative to the walls and frames.
  • a cabinet as just set forth the sidewalls and the door frame or frames are braced relative to each other by the base and the top. This is accomplished by virtue of the fact that the comers of the base and top are enflanked by abutment angles or the like which prevent the walls and door frames from falling inwards. With this kind of cabinet it is unnecessary for the sides and the frame to'be secured along their vertical edges and the hooks merely have to prevent the sides from being pulled apart. By appropriate dimensioning of the sidewalls relative to the base and top. a predetermined tension can easily be established, so that a fully shakeproof cohesion'is established.
  • the sides are of relatively simple form and can therefore be produced by sheet-metal working, by simple bending processes, without welding.
  • Welding is thus needed only for door frames, and this is acceptable since it is applied to only a small part of the cabinet.
  • the substantial elimination of welding has the advantage that it is possible, for example, to employ high-gradesheet steel or plastic-coated sheet metal, so that, for example, laboratory furniture can be built in the form of cabinets according to the invention.
  • the invention is not limited to application to sheet-metal structures. In a wooden structure, the interlocking parts and the abutment angles can be formed by special metal fittings.
  • the cabinet is collapsible it is easily transportable, and a plurality of the cabinets can be employed for erection of assemblies of lockers which may be set up in self-service sto'res.
  • Such lockers are of special advantage in supermarkets having two halls, between which a vestibule with entries and exits is situated. The lockers can be set up on the vestibule. The customers can then place their bags, etc in the lockers. After making purchases in one hall, baskets or trolleys carrying the goods can be locked up, leaving the hands free for purchases in the other hall.
  • the elements are provided with abutment angle members which are either bent over at right angles at their vertical sides or alternatively in the case of a door frame it is provided with vertical sections each having a portion bent over at right angles.
  • the longitudinal reinforcements of the sidewalls have their upper extremities acting as abutment angles.
  • a structure of this kind is extremely simple and offers great rigidity.
  • the distance between the upper end of an abutment angle and a bent over portion associated therewith is less than the height of the cover, said distance being preferably one-half that of the cover.
  • the lower abutment angles preferably project over the underside of the base by a distance equal to that by which the cover projects above the upper ends of the upper abutment angles.
  • the cover for a deep cabinet may be provided with slots arranged to receive base abutment angles of less deep cabinets.
  • the vertical sidewalls and the door frames may have identical upper and lower edges so that they may be installed in positions turned through around horizontal axes.
  • This has the advantage that a frame made as a door frame can be employed for doors intended to open to the left as well as for doors intended to open to the right, since the door hinges are positionedat the other side by*rotation of the cabinet through 180.
  • This ability to turn a cabinet also has the advantage that a lock arranged at the middle cannot be displaced to different vertical levels.
  • door frame when used herein is intended to include a frame surrounding an opening, which may, for example, be an opening for a drawer and which may be secured, as by screws, to the base and/or the top, preferably by means of bolts with wing nuts.

  • the cabinet system according to FIG. 1 comprises two identical and relatively large bottom cabinets la, 1b, adjoined laterally by smaller cabinets 2a to 2d.
  • the cabinet Ia supports cabinets 3 and 4, of which the cabinet 3 has two compartments and the cabinet 4 has three compartments, each compartment being closed by a door.
  • the cabinet 3 is of slightly greater height that the cabinet 4.
  • the cabinet lb carries small cabinets 5a, 5b which contain drawers, one of which is shown in the pulled out condition.
  • the cabinet 5a supports a cabinet 6 of the same size as that of the cabinets 2a to 2d. All the cabinets are assembled according to the principle illustrated in FIGS. 2 to 10, irrespective of size, which is described in detail below.
  • Each cabinet has a base 7 (see FIG. 2), a rear wall 8, a front door frame 9 and sidewalls 10, only one such sidewall, as well as a top panel 11 (see FIG. 6) being illustrated in FIG. 2.
  • the base 7 is formed from a plane sheet metal panel by bending the edges over twice at right angles, as apparent from the cross section according to FIG. 5. If need be, the base 7 may also have reinforcements.
  • the rear wall 8 has the shape shown in FIGS. 2 and 3. In essence, it consists of the actual wall surface 12 which has a bent over portion 13, FIG. 2, at the bottom and a bent over portion 14 at the top. The vertical edges are bent over to form hooks as illustrated in FIG. 3, that is firstly through 90 (at 15) and secondly through 180 (at 16). As can be seen from FIG. 2, the bent over portions 13, 14, are inset relative to the upper edges 17 and the lower edges 18.
  • the door frame 9 has the shape shown in FIGS. 2 to 4.
  • the lower member 19 of the frame 9 is an angle section, FIG. 2, and the upper frame member 19 is an identical angle section.
  • the vertical members are formed by identical sections 20, 20, shaped as shown in FIGS. 3 and 4.
  • FIG. 3 shows that the frame sections 20, 20 each have a portion bent over at 90 corresponding to the bent over portion 15 of the wall 8, and a bent over portion 22 at 180 corresponding to the bent over portion 21 (see FIG. 4).
  • a limb 220 is incorporated moreover, so that the vertical profiles 20, 20' each have a J shaped cross section with a flat base 24.
  • the frames 9 may also have a central post 23 which has the same cross section as that of sections 20, 20.
  • the base 24 is extended to form a weld-on lug 25, FIG. 4.
  • the sidewalls 10 each have a lower horizontal bent over portion 26 (see FIG. 2) and an upper horizontal bent over portion 27.
  • the configuration of the vertical edges is also shown in FIG. 3 from which it will be seen that the vertical edges are bent over through 180 to form hooks 28.
  • the cabinet is assembled in the following manner.
  • the rear wall 8 and the door frame 9 are initially placed on the base 7.
  • the two sidewalls 10 are then inserted from above, so that the 180 bends on the rear wall and door frame on the one hand and on the side walls on the other hand, interlock as shown in FIG. 3.
  • the bent over portions 13 of the rear wall 8 and 26 of the sidewalls are placed on the upper side of the base, whereas the lower frame member 19 enflanks the front edge of the base.
  • the top or cover 11 is then placed in position, being of analogous form to that of the base 7 i.e. being produced from a flat metal sheet or plate the edges of which are bent over at right angles twice.
  • the base 7 and the cover 11 hold the sidewalls in spaced relation in such manner that they cannot fall inwards.
  • the base 7 and the cover 11 also have the effect that the interlocking hooks I6, 28 (see FIG. 3) cannot be pulled apart.
  • the dimensions may easily be chosen in such manner that a definite state of stress is induced after insertion of the cover, which ensures that all parts of the cabinet are held together in wobbleproof manner.
  • Small guiding angles 30, FIG. 3 may be provided on the inner sides of the frame sections, to facilitate the assembly of the cabinet by preventing the sidewalls from falling inwards before positioning of the cover 11.
  • Screw-holes 31, FIG. 2 may be provided in the abutment angles, to make it possible to connect the interlocked cabinet parts by means of bolts.
  • the rear wall 8 may carry a rail 64 having hooks corresponding to the hooks 16, 22.
  • FIGS. 5 and 6 show a system consisting of several cabinets, the cabinets shown in section in FIG. 5 being the cabinets 3 and 4 of FIG. 1.
  • the height h of the cabinet cover 11 is greater than the distance a (see FIG. 2) by which the bent over portion 14 lies below the upper extremities 17 of the abutment angles.
  • the cover 11 extends above the upper extremities 17 by approximately the height h.
  • the cabinet 3 placed on top of cabinet la is so constructed that its lower abutment angles 29' project below the underside of the base of the cabinet, so that the front abutment angles 29 of the upper cabinet 33 enflank the cover 11 of the cabinet la at the corners, see also FIG. 1.
  • the cover 11 is provided with slots 31 FIG. 6, into which are inserted the rear abutment angles of the cabinet 3.
  • the cabinet 4 also has a depth and its lower abutment angles can therefore enflank all four corners ofthe lower cabinet 3.
  • the superimposed cabinets may be secured one to another.
  • 11 and 11' are covers of two adjacent. cabinets, say of the cabinets la and lb, FIG. 1, whereas 20' is a frame section of the lower cabinet 1a, 20 is a frame section of the cabinet 3, 20" is a frame section of the cabinet lb, and 20 may be a frame section of the cabinet 5a.
  • the adjacent cabinets are then interconnected by means of bolts 32 and wing nuts 33. To this end, the bolts 32 are inserted through holes 31 in the covers 11, l1 and in the frame sections 20.
  • FIGS. 8 and 9 illustrate the structure of a cabinet comprising a drawer.
  • the front opening frame of a cabinet say of the cabinet 5a, is shown dotted at 34 in FIG. 8.
  • the sidewalls, marked 35 and 36 in this case, and of which the partition 36 is shown in enlarged perspective in FIG. 6, are bent over at right angles twice, at the top, namely at 37 and 38, so as to form a Z-shaped cross section.
  • the upwardly projecting limb is bent over through at 39 and acts as a guiding rail for a drawer 40 whose lateral edges are bent over to U-shape at the top at 41, and enflank the guiding rails.
  • the distance b between the upper edge of the guiding rails and the lower edge of the upper frame member of the door frame is just sufficient to allow the drawer to be inserted whilst still leaving a small ga'p. Since the lateral side 36 acts as a delimitation for both cabinet compartments, it carries a part 42 acting as a guide rail for the drawer situated in the right-hand cabinet compartment. This guide rail is shown dotted in FIG. 9.
  • FIG. 10 shows the mounting of a cabinet door.
  • 7 is a cabinet base, 19 a lower door frame section and 20 a lateral door frame section.
