Locker Corporation,Pocahontas, Iowa, a corporation of Iowa Applicationuuly 2, 1937, serial 1510.151575 l2 claims. 01. L11i- 7) This invention relates to improvements in receptacles and more particularly to improvements in receptacles of the type capable of being shipped lin knockdown or disassembled condi- 5 tion.
One of thevparticular objects of the invention is to provide an improved receptacle construction of the knock down typev in which the unit may be assembled by unskilled labor and without tools or other equipment, the various parts automatically locking .each other in final position, such parts being readily formed from sheet stock by cutting and bending.
A more particular object of the invention is to provide a type of interlocking fold or grooved channel for the individual elements of a knock down receptacle by which all ofthe elements may be interlocked and held secure, such receptaclel being of especial ruggedness and rigidity.
A further object of the invention is to provide a knock down drawer construction that is entirely assembled by interlocking grooves and in which the front is adapted to be-used for the opening and closing of thevdrawer and with the bottom by the repeated in and out movement. of the drawer are, resisted directly by interlocking grooves.
Further objects and advantages. of my invention will be apparent from the following disclo` sure of' a preferred form ofV embodiment thereof, taken in connection with the attached drawings illustrative thereof', and in which,
Fig. l is a perspective View of the receptaclev in assembled position.
Fig. 2 is a perspective view of the inside of the front of the receptacle partially assembled. Fig. 3 is a perspective view of the outside of the rear of the receptacle illustrating another step 40 of the assembly. y
Fig. 4 is a transverse vertical section throug the receptacle looking toward the rear thereof.
Fig. 5 is a longitudinal vertical section through the receptacle before the front is interlocked.
Fig 6 is a longitudinal Vertical section through the receptacle as fully assembled.
Fig. '7 is a vertical cross sectional detail of the rear end of the bottom member and Fig. 8 is a horizontal cross section on the line 8 8 of Fig. 6 showingthe attachment of the front and back elements to the side.
One of the chief advantages of knock down receptacle construction, that it can be shipped in the minimum volume, is often the greatest disadvantage in that assembling requires either supported by the sides so that the forces set up` skilled labor andattaching devices, or the completed construction is unstable. andoff'such frail construction that itv isv readily ut out of com mission, and will not .withstand hard service conditions.
In accordance with one preferredv form of embodiment of my invention, 'I have shown a drawer structure as generally shown in Fig. l, the Velements of which include the side walls l and ma, the front wall l2, the rear wall M, and the bottom i6. No cover is shown on this construction although it will be apparent that a cover may be provided, if desired. Y
As shown in Figs.' 2 and fl, the bottom I6 is of generally rectangular shape and has a fold i8 of metal which is generally termed a fPhiladelphia fold extending above the plane of the bottom and along each longitudinal edge. Each of these folds includes the upturned marginal portion 18a, and the downwardly and inwardly open portion ISU.- rI'hese form a channel alongv the side edges of the bottom with which the sides il! interconnect. In addition the bottom has an inwardly open fold 20 at its front edge, with the portion Eso extending rearwardly slightly above the plane of d the bottom, such foldbeing adapted to engage the front walllZ ashereinafter described.
The sides l each have a fold` 2l along the bot-` tom edge which consists of an outwardly open portion Zia, the height of which is substantially equivalent to the height of the inwardly open fold portion [8b on the bottom. The sides also have outwardly open folds 2.2 along the front and lback vertical edges, which as shown in Fig. 3,
y tive side walls so that a tight interconnection is had between the front wall and side walls. Furthermore, the front wall has a downwardly opening fold 26 at the bottom edge which engages the fold 2!! on the bottom IE when the receptacle the front so that it has smooth edges and is of double thickness around the periphery.
The back I4 of the receptacle is relatively simple in construction, having the two side folds 25 which open inwardly and a relatively flat interlocking portion 21 which engages within a channel 28 carried by the bottom as shown in Figs. 3 and 7.
The assembly of the receptacle is as follows: The sides I0 and Illa are first engaged with the bottom I6 but with the bottom extending beyond the forward edge of the sides a substantial amount. The front can then be applied and interlocked with the sides and brought down to the position shown in Fig. 5. By sliding the bottom rearwardly, the folds 20 and 26 are then en`` gaged for a complete connection of the front wall to the bottom and side walls.
After this operation, the back is slid onto the sides, and the interlocking portion 21 engaged within the channel 28 as shown in Fig. 6 which is most simply formed by a welded interior Wall. The receptacle is then completed and held in an interlocked manner, no assembly tools or material being required.
It will be noted that the bottom is supported on three sides, including the front so that very substantial weights can be carried thereby. It
i will also be noted that the front is secured to the receptacle along three sides so that there can be no possibility of an accidental disconnection between the front and the rest of the receptacle. This effectively prevents damage due to the heavy pulling on the drawer front. Furthermore, the receptacle can not be disassembled except by removing the unit from its cabinet as the back must rst be raised Vto release the bottom. I
The receptacle is readily made out of sheet metal and can be shipped as knock down material at a very low transportation cost. The elements may be made in largequantities at low cost substantially entirely by a simple cutting and folding operation and the edges or corners are all reenforced. The folds may be changed if desired without changing the nature of the joints, but it is desirable to have the maximum width at the bottom so that the unit may be freely moved in a cabinet as a drawer, and with such an arrangement, folds on Vthe back come into align ment with the folds on the bottom for equal clearance. Furthermore, the inside of the receptacle is entirely smooth, except for the relatively small projection of the fold 26.
While I have shown a preferred form of embodiment of my invention, I am aware that modifications may be made thereto and I therefore desire a broad interpretation of my invention within the scope and spirit of the disclosure herein and of the claims appended hereinafter.
1. A knock down drawer of the class described comprising'a bottom member having a transverse inwardly opening fold alongthe front edge thereof, the side edges of said bottom 'member being 11p-turned and folded back on themselves to form longitudinally extending, vertical, inwardly opened channels, a pair of side wall members having outwardly opening folded metal channels along the bottom edges to interengage the channel members on the'l bottom member, said side wall members also having outwardly opening folded metal channels along the vertical edges, a front wall member having inwardly projecting, inwardly opening, vertical folded metal channels to engage the front, vertical channels on the side wall members, said front wall also having an inwardly projecting, transversely extending, bottom opening channel adapted to cooperate with the transverse fold on the bottom member, and a rear wall member inter-engagingthe rear vertically extending channels on the side wall members and the bottom member to prevent disengagement of the front wall member with respect to the bottommember, and thereby prevent the front wall member from disengaging the side wall members.
2. A knock down drawer of the class de scribed comprising side wall members, a bottom wall member, a front wall member, and a rear wall member, the adjacent edges of the respective members having inter-engaging folds whereby the respective members may be assembled by longitudinal movement, the transverse fold along the lower edge of the front wall member and the transverse front edge of the bottom wall member being laterally displaceable rearwardly and the joint between the lower edge of the rear wall member and the rear transverse edge of the bottom wall member being vertically Vdisplaceable and normally preventing rearward displacement of the front wall member with respect to the front transverse edge of the bottom wall member, the remaining joints being laterally xed whereby the rear wall in its connection to the side and bottom walls prevents disengagement of the front wall member and bottom wall member, and-l thereby locks all thel parts together.
