Abstract

Modular structure and method for constructing furniture and the like, wherein inexpensive, resilient connecting means is used to join together a plurality of normally discarded cans, such as soft drink and beer cans and the like, to construct useful items such as household furniture and decorations and the like with the discarded cans.

Description

BACKGROUND OF THE INVENTION

This invention relates to furniture and the like constructed from cans of the type which normally contain food stuffs or beverages or other materials and which are normally discarded after the contents thereof are emptied, and to unique structural modules and method for joining together a plurality of such normally discarded cans to form the furniture and the like.

The widespread use of cans made of steel, aluminum, tin and the like for the packaging of food stuffs and beverages and other materials for merchandizing and sale has resulted in a serious problem from an ecological standpoint. Heretofore, when the contents of such cans were emptied, the cans were discarded, and because of the nondegradable nature of such cans, a serious disposal problem existed. Such cans are not readily recycled for further use nor are they capable of being burned in incinerators or the like, and accordingly, the handling and disposal of such cans is both expensive and extremely difficult to accomplish, resulting in substantial damage to the ecology.

With the present invention, cans of the type which normally contain food stuffs, beverages and other materials and which are normally discarded after the contents thereof are emptied are usefully reclaimed by using the cans to make inexpensive furniture and the like. Therefore, the invention serves not only to eliminate such cans from the tremendous amount of garbage and other refuse that accumulates daily in populous areas, and to thus enhance the ecological balance in such areas but also results in the cans being used for making useful articles such as furniture and the like.

Moreover, the simplicity and exceptionally low cost of the unique structural modules of the present invention enables a person to construct his own furniture or other articles with the use of only a few simple tools, such as a pair of pliers and a screwdriver.

According to the invention, an unique and inexpensive connecting means is provided for quickly and easily releasably joining together a plurality of such cans to form various useful articles such as household furniture and decorations and the like.

A plurality of modified forms of connecting means and couplers are taught by this invention, and each of the connecting means and couplers comprises a resilient disc-shaped web member of one-piece molded construction and having an integral, axially extending, annular, peripheral flange or wall on at least one side for receiving and holding a can therein.

The disc-shaped web member or portion of the couplers or connecting members extends across the end of an associated can when in use to reinforce the coupler or connecting member and prevent undesirable distortion of the annular flange.

According to one form of the invention, the connecting member has an annular flange or wall on only one side thereof and the web accordingly serves as an end cap for covering the end of an end most can in a structure constructed with a plurality of cans and connecting members or couplers according to the invention. In this form of the invention, a central spacing button or projection is formed on the same side of the web as the annular flange and abuts the end of the can to maintain the web in a substantially flat planar relationship.

In another form of the invention, the coupler has an annular, peripheral flange on both sides of the web for joining a pair of cans together in end-to-end relationship. In this form of the invention, it is not necessary to provide a button or projection on the web for engaging the ends of the cans since the web is not exposed to view.

In yet another form of the invention, the coupler includes a pair of connecting members joined together in right angular relationship, with each of the members having an annular flange thereon for receiving and holding a pair of cans in angularly disposed relationship with regard to one another. More particularly, according to this form of the invention, a pair of cans are held in right angular relationship and more than two connectors may be joined together in mutually perpendicular relationship for joining together as many as six cans disposed in perpendicular relationship to one another.

In still another form of the invention, the outer peripheral surface of the coupler or connecting member has at least one channel or notch therein for receiving the edge of a panel or the like so that a plurality of joined together cans may comprise a framework for supporting at least one generally flat, rectangular panel. This form of the invention should be used, for example, to form a room divider or other similar article wherein at least one and preferably a plurality of flat rectangular panels are held in assembled relationship by means of a plurality of cans held together with a coupling or connecting means as aforedescribed.

Other articles of furniture and the like can readily be made with the present invention such as, for example, tables, floor lamps, table lamps, ashtrays, bookshelves, umbrella stands and the like. Of course, it is readily apparent that there are various other items which can be made with the unique coupler or connector means of the present invention and a plurality of cans of the type which are normally discarded.

OBJECTS OF THE INVENTION

It is an object of this invention to provide articles of furniture and other items which are constructed from cans of the type which normally contain beverages or food stuffs or other materials and which are discarded after the contents thereof are emptied, said discarded cans being held together in assembled relationship by means of resilient coupler or connector means between the ends of adjacent cans.

Another object of the invention is to provide articles such as furniture and the like comprising a plurality of normally discarded cans held together in assembled relationship by connecting means and to the method of making same.

A further object of this invention is to provide a means for quickly and economically joining together a plurality of cans of the type which normally contain food stuffs or beverages or other materials and which are normally discarded after the contents thereof are emptied, to form useful items such as furniture or the like.

An even further object of this invention is to effectively reclaim and put to a useful purpose cans of the type which normally contain food stuffs, beverages or other materials and which are discarded after the contents thereof are emptied and to thus substantially reduce the problem of disposing of such cans and to accordingly improve the ecology.

DETAILED DESCRIPTION OF THE INVENTION

Referring more specifically to the drawings, wherein like reference numerals indicate like parts throughout the several views, a structure comprising a plurality of cans C joined together by a simple inline coupler S and an angle coupler A, with a pair of end caps E and E' at the opposite ends thereof, is shown in exploded relationship in FIG. 1.

The end cap E, as seen best in FIGS. 1-5, comprises a disc-shaped web 1 with an integral annular wall or flange 2 projecting substantially perpendicularly from one side of the web 1 about the peripheral marginal edge thereof. A relatively short cylindrical button or projection 3 is in the center of the web on the same side thereof as the flange 2 and engages the end of an associated can C when in use to space the web 1 from the end of the can and maintain it substantially flat and planar. The edge of the flange 2 is turned radially inwardly to define an annular lip 4 which engages behind the flanged or beaded end of a can positioned therebehind as seen in FIGS. 3, 4 and 5.

The outer surface of the end cap or connector E of FIGS. 1 and 2 is of relatively straight cylindrical shape, whereas in FIG. 3, the outer surface is rounded; in FIG. 4, the outer surface has a cove shape; and in FIG. 5, the outer surface is beaded.

In FIG. 8, a modified end cap or connector E' is shown and is identical in every respect with the end cap or connector E of FIG. 1 except that a pair of radially projecting lugs or ears 5 and 6 project from the outer surface of the annular flange 2 and define a groove or channel 7 therebetween for receiving the edge of a flat rectangular panel.

In FIGS. 6 and 7, a still further form of end cap or connector E" is shown, and includes a web 1 and a central button or projection 3 for spacing the web from an end of an associated can C. In this form of the invention, a plurality of equally spaced tabs or projections 8 project radially outwardly from the outer surface of the annular flange 2 and define a plurality of notches or channels 9 therebetween for receiving the edge of a panel P. The web 1 extends radially outwardly beneath the notches or channels 9 to define a stop 10 for the bottom edge of the panel P.

In FIGS. 1 and 9 through 13, the simple inline coupler S is shown and comprises a flat, disc-shaped web 1' with an annular peripheral flange 2' projecting substantially perpendicularly from each side thereof about the marginal edge of the web 1'. The edge of each flange 2' is turned radially inwardly to define an annular retaining lip 4 for gripping and holding the flanged or beaded end of a can C therebehind when the coupler S is placed over the ends of adjacent cans.

In FIG. 1, the coupler S has a relatively straight cylindrical outer peripheral surface and in FIGS. 9 and 10, the outer peripheral surface of the coupler S is semi-circular. In FIG. 11, the outer surface of the coupler is cove shaped, and in FIG. 12, the outer surface is beaded.

In FIG. 13, a modified coupler S' is shown and is substantially identical with the form of the invention shown in FIG. 1, except that a plurality of radially outwardly projecting ribs or flanges 12 are formed on the outer surface of the flange 2' to define a plurality of equally spaced channels 13 therebetween for receiving the edge of a panel P. A radially inwardly directed lip 4 is on each flange as in the previously described embodiments of the coupler S for receiving and holding the flanged or beaded ends of cans C therein on opposite sides of the web 1'.

Referring to FIGS. 14 and 15, a further form of in-line coupler SR is shown, and in this form of the invention, the coupler comprises a reducing coupler for joining two cans of different size together in end-to-end relationship. The reducing coupler SR comprises a disc-shaped web 14 increasing in thickness toward its outer peripheral edge and having an annular peripheral flange 15 formed integrally with the web 14 at the peripheral edge thereof and extending substantially perpendicularly from one side of the web. The edge of the flange 15 is turned radially inwardly to define a lip 16 for gripping and holding the beaded or flanged end of a can C' therebehind. The size of the web 14 and flange 15 is such as to accommodate a typical one gallon can C'. A plurality of notches 17 are formed in the lip 16 about the circumference thereto to enable air to escape from behind the flange 15 when the end of the can C' is placed in operative position against the web 14 and behind the lip 16. A diametrically smaller flange 18 is integrally formed on the other side of web 14 generally concentrically with the axis of the coupling SR and the edge of the flange 18 is turned radially inwardly to define a lip 19 for receiving and holding the beaded or flanged end of a can C placed therebehind. The size of the flange 18 is substantially the same as the size of the flanges 2 and 2' previously described for holding and receiving the end of a typical can such as a food or beverage can or the like.

Two forms of decorative rings R1 and R2 are shown in FIGS. 26 and 27, respectively. The rings R1 and R2 are positionable about a can C intermediate the ends thereof to enhance the aesthetic effect of a structure made in accordance with the invention.

A modified form of end cap E" is illustrated in FIGS. 28 and 29 and has a substantially flat, planar disc-shaped end wall 1 with a central axially projecting button or stop 3 as in the first described form of end cap, but rather than a short cylindrical flange or wall 2 as in the first described form of end cap, the end cap E" has a long wall 2" with a circular or cylindrical inner configuration O and a rectangular outer configuration. The lower or open end of the side wall 2" is turned radially inwardly to define a lip or flange 4 as in the previous embodiment and a plurality of notches or grooves 17 are formed through the lip to enable air to escape from the interior of the end cap when it is placed over the end of the can C.

A modified coupler S" is illustrated in FIGS. 30 and 31 and is substantially identical to the coupler S except that relatively long walls or flange 2" extend from opposite sides of the central web 1' and the outer or open ends of the walls 2" are turned radially inwardly as at 4 to define a retaining flange for holding the end of an associated can therebehind. The configuration of the coupler S" is similar to the configuration of the end cap E" in that the hollow interior of the coupler has a circular or cylindrical configuration as at O and the exterior of the coupler has a rectangular or square configuration. Notches or slots 17 are formed through the lip 4 for enabling air to escape from the interior of the coupler when cans C are inserted thereinto.

In FIGS. 32 and 33, a modified angle coupler A6' similar to the angle coupler A6 is illustrated, and this form of angle coupler is substantially identical to the angle coupler A6 except that the exterior configuration of the angle coupler A6' is rectangular or square in shape and comprises a first connector 34' joined in right angular relationship to a second connector 35', each of the connectors having circular or cylindrical openings or bores O therein for receiving an associated can C. The connectors have elongated walls or flanges 2" thereon which surround the end portion of a can C inserted within the cylindrical bores or openings O.

In FIGS. 34, 35 and 36, a modified form of angle coupler A1' is illustrated and is similar to the angle coupler A1 shown in FIG. 1. The angle coupler A1' differs from the angle coupler A1 in that it has relatively long walls or flanges 2" extending in opposite directions from the web 1', and the outer configuration of the coupler A1' is rectangular rather than circular as in the form of coupler shown in FIG. 1.

In FIG. 37 a modular structural element 52 for use in constructing articles of furniture and the like is illustrated and comprises a plurality of cans C superposed one upon the other and releasably joined together in end-to-end relationship by a plurality of the unique coupler means S. An end cap E is positioned over the outer end of the end most cans in the column of cans, and the bottom most can may be filled with a suitable ballast material 53, such as sand or the like, if desired. The structural element 52 may be used as a standard or base for supporting an item such as an ashtray, table top, lamp, or the like, as illustrated in FIGS. 38 through 43.

A lamp L constructed in accordance with the invention is shown in FIG. 38, and comprises a plurality of cans C joined together in superposed, end-to-end relationship by a plurality of couplers S. A relatively large can, such as a typical one gallon can C' comprises the bottom most can in the lamp and is joined to the remaining cans C by a reducing coupler SR'. Suitable ballast 53 such as sand or the like is in the bottom can C' to prevent tipping of the lamp.
