- This invention provides a pigeonhole-type storage rack, stand or the like constructed for the most part of a plurality of interlocking duplicate members, preferably precast, extruded or molded and made of concrete, having at least two parts orientated at right angles to each other, assembled together without the use of hand tools, and which racks, etc., may be free standing and can be readily sized or expanded as required.
- FIG. 1 is a fragmentary perspective view of a storage area having pigeonhole racks embodying the present invention
- FIG. 2 is a fragmentary enlarged view of the near end of the right-hand rack shown in FIG. 1;
- FIG. 3 is a view similar to FIG. 2, but showing a different embodiment of the invention.
- FIG. 4 is a view similar to FIG. 2, but showing a further embodiment of the invention.
- FIG. 5 is a view similar to FIG. 2, but showing a further embodiment of the invention.
- the storage area illustrated in FIG. 1 may be a warehouse or merely an area in a factory or the like.
- the area includingthe storage racks are, in the illustration, serviced by a so-called stacker crane.”
- the storage area and/or racks could be serviced manually or by other suitable power-actuated material handling apparatus, for example, so-called fork lift trucks," preferably of the side-loading type.
- the racks shown in FIG. 1 are designated R, R, R and R, are of the pigeonhole type, and are arranged facing one another with service aisles between each two adjacent racks.
- the racks R and R are duplicates of one another, as are the racks R and R. While the racks R and R are shown twice as wide as the other racks it will be apparent that one or more racks of any size may be employed.
- the stacker crane shown designated generally by the reference character C, is of commercial construction, is of the floor supported, self-drive type guided in its travel along the racks and/or through the aisles between the racks by floor rails and overhead rails 11 suspended from the building superstructure B.
- the crane C is adapted to be moved from the aisle to another or to a loading station by having its upper end moved into an overhead bridgelike crane carrier A, movable along an overhead runway W suspended from the building superstructure B at the near ends of the racks.
- the overhead carrier A of the crane C includes mechanism for lifting the crane proper free of the floor to permit movement thereof by the carrier along the near ends of the racks.
- the crane C includes an L-shaped load carrier l3 vertically movable along the crane mast 14, which load is provided with a transversely movable load support 15 that can be extended into the pigeonholes or compartments of the racks to place loads therein or remove loads therefrom.
- the rack R comprises a plurality of duplicate L-shaped members E stacked upon a base member F and upon each other to provide a storage rack comprising a plurality of pigeonholes or compartments each adapted to receive a palletized load P.
- Each of the members.E comprise two main sides or parts 20 and 22 of approximately equal thickness, arranged with respect to one another like the two sides of a right angle. With the members E in the positions illustrated, the vertical parts 20 form the vertical sidewalls of adjoining side by side pigeonholes and the horizontal parts 22 of the tops and bottoms of vertically arranged pigeonholes.
- each of the members E is provided with a flange 24 which may be considered as an extension or continuation of the horizontal part 22, and directly opposite the vertical part 20 the top side of the member or the top side of the part 22 is provided with an inverted V-shaped interlock tongue or ridgelike projection 26.
- the projection 26 preferably extends the length of the member E.
- the righthand end 28 of the horizontal part 22 is offset vertically in an upwardly direction with respect to the left-hand end thereof a distance equal to the thickness of the part proper, has a thickness greater than that of parts20, 22 of the member E. and has formed therein vertically aligned top and bottom V- shaped interlock apertures or grooves, 30 and 32, respectively.
- the lower or bottom side of the verticalpart 20 is beveled and terminates in a downwardly projecting V-shaped interlock tongue or ridge 34.
- the bevel along the-lower edges of the vertical part 20 could be omitted if desired. In this event the lower edge of the part 20 would interlock or interengage with the member therebelow and form the interlocking or interengaging projection of the member.
- the construction of the members E is such that when the members are stacked in horizontal rows one upon the other the lower portion of the vertical part'20 of the member being stacked engages in the aperture or groove 30 in the top side of the offset part 28 of the member E in the horizontal row below and in the vertical row immediately to the left of the vertical row in which the member is being placed.
- the groove 32 in the bottom side of the offset part 28' of the member being stacked engages over the tongue or ridge 26 of the member immediately to the right and in the same horizontal row.
- the member E being stacked when in position, together with the horizontal part 22 of the member E immediately below and the vertical part 20 of the member E'immediately to the right form a pigeonhole.
- the portions of the parts '28 at facing or adjoining sides of adjacent vertical parts 20 provides shelves or supports for receiving the load P, shown in phantom lines, placed thereon by the load carrier 15.
- the top sides of the parts 28 are sufficiently high above the top of the main portion of the part 22 to allow the load carrier to move freely into and out of the pigeonholes underneath a load therein.
- Similar load supporting ridges 40 are provided in the upper side of the base member F.
- the floor or base member F has, in addition to the load-supporting ridge 40, a plurality of horizontally spaced grooves 36 in its upper surface into which the tongues or ridges 34 of the first horizontal row of members E engage. Because there are no members, comparable to the members E, at the left of the left or near terminal vertical row of pigeonholes. small members H, similar in construction to the offset parts 28 of the members E, are provided for interposition between the lower or bottom sides of the vertical parts 20 of the members E which form the left-hand end of the rack, with the exception of the vertical part 20 of the lower member E, the lower end of which merely engages in the left end or near V-shaped groove 36 of the base member F.
- members E which are generally similar to the members E, are used toconstruct the-terminal right-hand vertical row of members.
- the members E are each generally U-shaped in cross section having vertical parts 42 projecting downwardly from the horizontal part 22 which corresponds to the horizontal part 22 of the member E.
- vertical parts 42 are constructed similarly to and takes the place of the vertical parts 20 of the members E if the rack was to be extended to the right.
- the parts of the members E are identified on the drawings with the same reference characters as those employed for the corresponding parts of the members E, but with a prime mark afiixed thereto.
- stacking of the members E and E is begun by first positioning the lower right-hand member E on the base member F. The stacking then proceeds in an obvious manner.
- the members E and E' can be stacked upon the base member and upon one another by use of the stacker crane shown, if desired. As illustrated in FIG. 1, a member E to be positioned in a rack can be placed upon a member 42 on the transversely movable load support of the vertically movable load carriage 13 at a loading station and moved by the crane to its position in the rack.
- the members E and E can be stacked in any suitable manner, for example, by hand or by use of a fork lift truck of the character previously mentioned.
- the rack R is a duplicate of the rack R, previously described, with the exception of the fact that the members thereof which correspond to the members E and E of the rack R are twice as long as the members E and E.
- the members E, E', F and H are made of precast concrete. However, they may be made of any suitable material other than concrete, for example, fiber glass, plastic, etc., and formed in any desired manner as by casting, extruding, molding, etc. When made of concrete they are preferably reinforced by having steel mesh or rods embedded in the concrete.
- the interlocking tongue and grooves lock the members together forming a free standing rack which may be built to any desired height or added to as required.
- the rack may be readily disassembled and moved to another location, if desired, and when made of precast concrete is fireproof.
- An integral construction may be produced by using a thin layer of suitable adhesive or cement in the joints during building of the rack.
- the rack 2R shown in FIG. 3, is constructed of members 2E, 2E, 21-! and 2F comparable to the members E, E, and F and H of the rack R, but of different construction.
- the members 2E of the rack 2R are precast L-shaped members having two main parts or sides 50, 52 of approximately equal thickness at right angles to one another like the two sides of a right angle. With the members E in the positions illustrated, the vertical parts 50 form the vertical sidewalls of adjoining side-by-side pigeonholes and the horizontal parts 52 the tops and bottoms of vertical arranged pigeonholes.
- each of the members 2E is provided with a flange 54 similar to the flange 24 of the member E, and directly opposite the vertical part 50 the top side of the member or the top side of the part 52 is provided with an inverted V-shaped interlock groove 56 preferably extending the length of the member 2E.
- the right-hand end 58 of the horizontal part 52 is offset vertically in an upwardly direction with respect to the left-hand end thereof a distance approximately equal to the thickness of the part proper, has a thickness approximately equal to that of the parts 50, 52 of the member 2E, and has formed therein a vertically aligned top and bottom V-shaped interlock groove and tongue or ridge 60 and 62, respectively.
- the groove 60 is wider than the thickness of the lower or bottom end of the vertical part 50.
- the construction of the members 2E is such that when the members are stacked in horizontal rows one upon the other the lower end of the vertical part 50 of the member being stacked constitutes a projection on the member which engages in the groove or aperture 60 in the top side of the offset part 58 of the member 2E in the horizontal row below and in the vertical row immediately to the left of the vertical row in which the member is being placed.
- the tongue 62 in the bottom side of the offset part 58 of the member being stacked engages in the groove 56 of the member immediately to the right and in the same horizontal row.
- the portions of the parts 58 at facing or adjoining sides of adjacent vertical parts 50 are not necessarily high enough to receive a load P on the load carrier 15, and in this instance the top sides of the parts 52 of the members 2E and 2F are provided with horizontal ribs 70, 72 sufficiently high above the top of the main portion of the part 52 to allow the load carrier to move freely into and out of the pigeonholes underneath a load therein.
- small members 2H similar in construction to the offset parts 58 of the members 2E, are provided for interposition between the lower or bottom sides of the vertical parts 50 of the members 2E which form the left-hand end of the rack, with the exception of the vertical part 50 of the lower member E, the lower end of which merely engages in the left end or near V- shaped groove 66 of the base member 2F.
- the load support 15 of the crane C must be so constructed as to be projectable into the pigeonholes between the ribs 70 and 72.
- members 2E which are generally similar to the members 2E, are used to construct the terminal right-hand vertical row of members.
- the members 25' are each generally U-shaped in cross section having vertical parts 74 projecting downwardly from the horizontal part 52' which corresponds to the horizontal part 52 of the member 2E.
- the vertical parts 74 are constructed similarly to and takes the place of the vertical parts 50 of the members 2E if the rack was to be extended to the right.
- the parts of the members 2E not herein specifically referred to, are identified on the drawings with the same reference characters as those employed for the corresponding parts of the members 2E, but with a prime mark affixed thereto.
- the members which make up the rack 2R are assembled to build the rack in a manner similar to that in which the corresponding members are assembled to build the rack R.
- the rack 3R shown in FIG. 4, is formed of a multiplicity of duplicate members 3E, 3E and 313" of inverted U-shape, somewhat similar to the right-hand terminal members of the previously disclosed racks, stacked up on base members 3F.
- the lower portions of the vertical parts 80, 82 of the members 3E constitute projections adapted to engage in apertures or channels 92, 90, respectively, formed along the left and righthand edges of the top sides of the horizontal parts 94 of the members in the horizontal row of members therebeneath.
- the upper portions of the vertical parts 80, 82 of the members 3E are enlarged or flared, as viewed in transverse cross section, so as to better accommodate the apertures or grooves 90, 92, etc., and to provide projections or raised portions 96, 98 for the reception of a load.
- the raised portions 96, 98 are similar to the raised portions 28 of the members E of the rack illustrated in H6. 2.
- the members 3E of the rack 3R, in any horizontal row, are spaced from one another such that the two vertical parts 80, 82 of a member in an upper row rest upon the top adjacent edges of two spaced members in the row below with the result that the horizontal parts 94 of the members in any vertical row are spaced apart a distance equal to twice the height of the members 3E with the parts 94 alternating or offset with respect to one another in adjoining vertical rows.
- Each pigeonhole is constructed to receive two loads since there are two pairs of spaced load receiving abutments 96, 98 in each pigeonhole.
- a rectangularly shaped rack such as, the rack 3R shown, may be constructed by using in the terminal left and right vertical row members, such as, the members 3E and 3E'. These members are similar to the members 3E except that their left and right-hand vertical sides, and 82, respectively, are twice as high as the sides 80 and 82 of the members 3E and have flared parts intermediate their ends forming abutments 96' and 98' to cooperate with the opposite abutments in the same opening for receiving a load.
- the base member 3F is generally .similar to the base member F, shown in FIG. 1, except that the apertures or grooves 100therein, which receive the projecting lower ends of the vertical sides of the members 3E are formed in the top side of raised ribs 102, the upper surfaces of which form loadsupporting abutments for the reception of loads placed adjacent to the base member.
- the top of the stack can be tied together by a plurality of platelike members it having downwardlyprojecting tongues or ridges 104, 106 along the left and right-hand parts, respectively, of the undersides thereof, as viewed in FIG. 4, which ridges engage in the grooves in the top sides of adjoining members 3E, 3E and 315", as the case may be.
- the rack SR is formed by first locating the base member on a suitable support and then stacking the members'SE, 3E and 3E" thereon and upon one another in a manner similar to that in which the members forming the previously described embodiments are stacked.
- the rack 4R is formed of a plurality of duplicate members 4E, 4M stacked upon a base member 4F.
- the members 4B are tubular members generally rectangular in cross section having left and right sides 110, 112 and top and bottom sides 114, 116.
- the lower left and right corners 120, 122 of the members 413 are relieved, as indicated in the drawings, so that as the members are stacked one upon the other the right and left-hand corners of the members 4E, in the row immediately therebelow, are received in or interengaged in the apertures thus formed.
- each of the members 4E is provided with upstanding projections or ridges 124,126 along their left and right-hand edges but spaced slightly inwardly thereof a distance equal to the thickness of the vertical walls of the members 4E to receive and interengage with the adjacent corners of the member 4E immediately thereabove.
- these walls are formed in alternate pigeonholes by the members 4M which are platelike in form and have their upper edges received and secured in the lower cutout portions or apertures in the members 4E immediately thereabove and their lower edges received adjacent to and interengag'e with either the projection or ridge 124 or the projection or ridge 126 of the member 4E immediately therebelow depending upon whether the left or the right-hand terminal row of members 4B is referred to.
- the upper and lower ends of the members 4M can be secured, as by adhesive or cement to the members 4E.
- the base member 4F has on its top side a plurality of transversely extending projections or ridges 130, 132, 134, 136 for locating and interengaging with the lower row of members 4E thereon and forming abutments for the reception of loads placed in the pigeonholes formed by adjacent members 4E resting upon the base member F.
- the base member 4F is located on a suitable support and the other members assembled thereon in a manner which it is believed is obvious from the description of the previous embodiments of the invention shown in FIGS. 1 to 4.
- the members 413 above can be assembled on the base member 4F to form a rack. It is to be understood that the members forming the racks R3 and R4 can be constructed of any suitable material including-the materials previously men-.
