With particular reference now to FIG. 2 the numerals 20, 40, 60 and 70 denote four basic modular units of the subject invention.
The numeral 20 denotes a modular H type base unit which comprises a pair of upstanding vertically spaced end members 22 and 24 centrally interconnected by means of transverse member 26. The end members include an outer surface 21 and a pair of similar inner surfaces 23, one above and one below transverse member 26. The upper surface 25 of end members 22 and 24 is provided with spaced sockets 27 whereas the lower surface 29 of each of said end members is provided with projecting tongues 30 which are dimensioned to be received within sockets 27 of the upper surface 25 of a similar base member for securely, though releasably, securing a pair of base members to one another in vertical alignment, as in FIGS. 15 and 16.
Transverse member 26 includes an upper surface 32 provided centrally with a socket 34, as illustrated. In the preferred embodiment of the invention the socket 34 does not extend through member 26 to its under surface 35, note FIG. 16.
The depth of end members 22 and 24 and transverse member 26 from their respective forward edges 36 to their rear edges 38 is the same.
- The numeral 40 denotes another type of modular unit, to wit, an open ended canister defined by upper and lower walls 41 and 42 interconnected by side walls 43 and 44 and a rear wall 45 whereby to provide an opening opposite rear wall 45.
A downwardly projecting tongue 46 is provided on the bottom surface 47 of lower wall 42, said tongue being adapted to be securely though releasably received within socket 34 in the upper surface 32 of transverse member 26 of a modular base unit 20, as in FIG. 7.
In the preferred embodiment of the invention, the overall width of a canister as defined by the lateral spacing of the outer surfaces 48 of side walls 43 and 44 is of a dimension whereby the canister may be slidably received between the inner most or adjacent surfaces 23 of end walls 22 and 24 of a base unit 20. The depth of the canister between the outer surface 50 of rear wall 45 and the forward edges 51 of Walls 41, 42, 43 and 44 is. preferably substantially equal to the depth of the transverse and end members of a base unit 20.
The overall height of the canister illustrated in FIGS. 1 through 4 is substantially equal to the height of inner surface 23 of the end members 22 and 24 of a base unit 20.
The numeral 60 denotes a modular cap member having a substantially flat upper surface 61 and a lower surface 62 from which a pair of tongue members 63 project, said tongue members being dimensioned to be received within sockets 27 in the upper surface 25 of end members 22 and 24, for the purpose of concealing said sockets, as best illustrated in FIGS. 1, 9 and 18.
The numeral 70 denotes a single drawer modular unit comprising an outer front or forward panel 71 connected at 72 to an inner forward wall 73, a rear wall 74, side walls 75 and 76 and a bottom wall 77. The numeral 78 denotes a hand grip formed in front panel 71.
With particular reference now to FIGS. 2 and 5, the numerals 80 denote tracks which are formed integrally with the inner surfaces of the side walls 43 and 44 of the canister. Each track 80 includes and is defined by a pair of vertically spaced upper and lower guide members 83 and 84 which extend outwardly of, that is, they project from their respective side wall surfaces.
The numeral 90 denotes a follower provided integral with and lengthwise of the outer surface 91 of the side walls 75 and 76 of the drawer, said follower having portions 92 and 93 which are complementary to and dimensioned for cooperation and the upper and lower guide members 83 and 84 of track 80 whereby 70 may be slidably received within a canister 40.
It will be noted that the forward or outermost end of track 80 terminates inwardly from the forward, open ends of side walls 43 and 44 of the canister, said forward ends being engaged by rear surface 95 of the forward panel 71 of the drawer, as clearly illustrated in FIG. 4. In this manner the fully closed position of drawer 70 relative to its associated canister is effectively established.
As best illustrated in FIG. 7, the lower surface 96 of the bottom wall 77 of drawer 70 is spaced from and above the upper surface 97 of thhe lower wall 42 of its associated canister 40.
With reference to FIG. 8 it will be noted that the side edges of tongues 63 may be tapered outwardly whereby to interlock with complementary shaped side walls of the sockets 27 in the upper surface of the end members of the base units 20.
In FIG. 9 the numeral 300 denotes a modular canister which is similar in all respects to canister 40 of FIGS. 1 through 4 except that it is twice as high and, as illustrated in FIG. 10, it is provided with two sets or pairs of tracks 80, one for each of drawers 7 0.
In FIG. 11 I have illustrated a canister 300 in association with the shelf member 100 and a pair of doors 102. The opposite side edges of shelf 100 are provided with followers 90 similar in design to followers 90 on the side walls of drawers 70.
Each door 102 is fabricated from rigid plastic with upper aand lower hinge-forming bosses 1 04 and 106 projecting outwardly from the upper and lower edges 103 and 105. The bosses are dimensioned for pivotal mounting within sockets 107 and 109 provided respectively in the lower and upper surfaces 108 and 110 of the upper and lower walls 301 and 302 of canister 300.
Each of the doors 1 02. may be hingedly secured to a canister by transversely flexing said doors about their upper and lower edges by an amount to permit reception of bosses 104 and 106 wherein their respective sockets 107 and 109 of the canister 300. Each door may be provided with an integrally formed hand grip portion 111 as illustrated in FIGS. 11 and 12.
In FIG. 13 I have illustrated, on an enlarged scale, the manner in which shelf 100 is slidably received within track element 80 of the canister.
In FIG. 14 the relationship between boss 104 of door 100 and socket 105 in the upper inner surface of top panel 301 of canister 300 has been illustrated.
FIGS. 15, 16 and 17 illustrate the manner in which a pair of modular base units 20 are interconnected such as, by way of example, when providing the various assemblies as illustrated in FIG. 18.
With particular reference now to FIG. 18, I have disclosed the aforesaid modular units assembled in three vertical tiers designated A, B and C. Vertical tier C has been assembled by placing a canister 300 on transverse 4 member 26 of the lowermost base member D with tongue 46 of the canister received within socket 34 of transverse member 26 for thereby securely though releasably locking the canister relative to base unit D.
Next, a base unit E is lowered downwardly over the upper portion of canister 300 for disposing the lower surface 29 of upper unit E (see FIG. 15) in abutting relationship with upper surface 25 of lower unit D and with the tongues 30 of upper unit E received in interlocking relationship with sockets 27 provided in the upper surface 25 of lower base unit D.
A canister 300 is then placed on transverse member 26 of base member E with tongue 46 received within and engaging socket 34 of transverse member 26 of base member E.
Base member F is then associated with base member E in the same manner in which base member E was initially associated with base member D.
A single drawer canister 40 was then associated with transverse member 26 of uppermost base member F to which it is secured against accidental or unintentional displacement by reason of the inter-engagement of tongues 46 and sockets 34.
Tier C was completed by inserting a shelf 100 in the track means of the lowermost canister 300 after which doors 200 were associated with said canister-or, if desired the shelf 100 and drawers 102 may be already associated with canister 300 at the time when it is associated with lower base member D.
Drawer units are associated with the upper canister '300 and the topmost canister 40 after which cap strip 60 may be associated with the upper ends of the side walls of the uppermost base member F.
In tier B a canister has not been associated with base members E and F, as in tiers A and C, for thereby providing an area Q open at opposite ends and which extends from the upper surface of transverse member 26 of base member E to the lower surface of transverse member 26 of base member F.
It should, of course be fully understood that FIG. 18 has been presented merely for the purpose of illustrating typical furniture and/or cabinet units which may be fabricated from the various modular units of the present invention; it being understood that any number of other combinations may be constructed from the basic modular units.
With particular reference now to FIGS. 19 and 20 the numeral 400 denotes a two-drawer canister having an overall dimension similar to those of canister 300 of FIG. 10, including sockets 107 and 109 for the reception of bosses 104 and 106, respectively of doors 102 (of FIG. 11).
The numeral 180 denotes a centrally disposed double track assemblage which comprises an upper track 182 and a lower track 184 defined by members 181, 183 and 185 respectively. The track assemblage 180, like track assemblage of FIG. 11, is preferably formed integral with the inner surface of each of the side walls of the canister.
The numerals denote drawers which include an outer front wall 71, a rear wall 74, side walls 75-76 and a bottom wall 77. The drawers of FIGS. 19 and 20 differ from the drawers of FIGS. 2, 5 and 10 in that the side walls 75 and 76 are provided with or terminate in an upper, outturned track follower 172 and a lower outturned track follower 174, adjacent the lower end of the side walls. The said followers are formed integral with their respective side walls.
As clearly illustrated in FIG. 20, the lower track follower 174 of upper drawer 170A is received within track 182 whereas the upper track follower 172 of lower drawer 170B is received within lower track 1 84. It should be fully understood that the disclosed structure permits the drawers to be interchanged since either drawer may be slidably associated with a canister from upper followers 172 or lower followers 174.
It should be further understood that shelf 100 may be associated with the upper or lower tracks 182-184 of the track assembly 180.
