FIGJO ENCLOSURE STRUCTURE FOR MODULAR SYSTEM This application is a divisional application of copending application Ser. No. 278,362, now US Pat. No. 3,791,528 entitled Enclosure Structure for Modular System, filed Aug. 7, 1972.
This invention relates to an enclosure for handling, storing, transporting, and distributing articles throughout a modular system. A specific aspect of the invention relates to a container module of unitary construction with interconnecting means for cantilever suspension of the module. An easy-access container module is provided with internal support for articles being handled and enclosure cover means to maintain such articles dust-free.
In commercial establishments requiring handling of numerous small items, for example in hospitals, a need has existed for more efficient and more economic handling of supplies. A modular system for such need is described in applicants copending application entitled Modular Storage, Transfer Handling, and Retrieval System, Ser. No. 278,362 now US. Pat. No. 3,791,528 filed Aug. 7, 1972. Important to a modular system as conceived by applicant is a container module providing easy access, ease of stable mounting in vertical orientation, means for level disposition on horizontal surfaces, stable stacking capabilities, light-weight, high carrying capacity with partitioning means for separation and holding of articles in fixed and distinct relationship, ease of washing and cleaning, easily operable cover means for protecting container contents, and economy in manufacture and use.
As a part of the inventive concept, a container module for use in a modular system should be capable of being readily suspended on vertically oriented support means by movement of the container module with article carrying surfaces horizontally oriented without need for tilting in any direction. Interconnecting means for coacting with the vertical support means should be located on the container module so as not to interfere with handling of such articles and to unobtrusively occupy a minimum amount of space; in other words, to maximize on carrying capacity and present no protrusions likely to interfere with handling of the container module or to break easily. Moreover, the interconnecting means should provide self-seating characteristics without need for manipulation of fastening or securing means to obtain stable mounting. The module should also provide for ease of application of cover means capable of maintaining enclosed articles in dust-free condition, means for stably positioning internal partition means, and stacking capabilities to enable container modules to be stably stacked independent of support structure while occupying minimum space.
The container module should be capable of use with, on, or in association with any structure wall, floor, or ceiling, i.e., horizontal or vertical surface area, or with apparatus such as carts, retrieval racks, elevators, and the like. In brief, a standardized article carrying module, universally usable throughout the modular system without need for selection as to size, shape, or support.

Container module 30 of FIG. 1 is mounted on support means 31. Such support means is vertically oriented and includes elongated horizontally oriented slot means, such as 33, spaced longitudinally along the support means as described more particularly in applicants copending application Ser. No. 278,360, filed Aug. 7, 1972 entitled Modular Storage, Transfer Handling and Retrieval System." Support means 31 includes lateral side edge means 33, 34, e.g., lateral sidewalls.
Various features of and accessories for the container module of the invention are shown in general arrangement perspectives in FIGS. 2 through 7. As shown in FIG. 2, container 30 is generally rectilinear in configuration, defining a substantially right-angled hexahedron enclosure, with full-open access upper portion 37 and full-open front portion 38. Also shown in FIG. 2 is a transparent one-piece cover 39 which seats on container 30 in the manner shown in FIG. 3 and seals the container against entry of dust as described in more detail in applicants copending application Ser. No. 278,361, filed Aug. 7, 1972 entitled Self-Seating Container Module Cover." In FIG. 4 a vertically oriented retainer bar means 41 is positioned at the front of the container module to prevent articles on the bottom of the enclosure from rolling or sliding out. In FIG. 5 a horizontal shelf means 44, which can be provided with one or more vertical partition means, such as 45 is positioned within the container module. In place of the removable horizontal shelf means 44, the module can be provided with an open framework means, such as bottle rack 46, as shown in FIG. 6. Either the shelf means or open framework means can be used with a front retainer means.
FIG. 7 shows novel interface structure for stable cantilever suspension of the container on an upright support and one of the handgrip openings centrally located along the sides of the container module so that the module can be easily grasped and lifted from a planar horizontal surface.
THE CONTAINER MODULE As shown in FIG. 2, container module 30 has bottom wall means 49, upright side wall means 50 and 51, and rear wall means 52 defining in combination an enclosure with open-access from above and front. At the front edge of bottom wall means 49, flange means 53 depends downwardly defining a vertically oriented planar surface extending between lateral sides of the module. Side wall means 50, 51 include inwardly directed flanges 54 and 55, respectively. Each of these flanges has a substantially planar vertically oriented surface; these flange surfaces are coplanar and define the front face of the container module. Such front face lies in a substantially vertical plane when container module 30 is mounted on a support (FIG. 1) as well as when the container module is placed on a horizontal surface (FIG.
A narrow surface is defined by the upper top edges of side wall means 50, 51 and rear wall means 52. This surface is generally horizontal when the container module is in its normal upright position. These edge surfaces are coplanar around the top of the side and rear walls. An exterior surface along each top edge of the walls 50, 51, 52 is chamfered; e.g., contiguous to top edge 57 of side wall means 50 chamfered surface 58 slopes outwardly from the narrow width top edge surface 57 to the full thickness of the side wall.
Four support posts 60, 61, 62, 63, seen in plan view in FIG. 9 and in various side views in FIGS. 8, 10, and 12, are distributed at respective interior corners of container module 30. These are provided for support of shelf means 44 or open framework means 46. Support post 61 at the front of the enclosure extends vertically on upright wall means 51 in contiguous relationship with upright flange 55. Preferably, spacing between support posts 61 and upright flange 55 is provided for supporting retainer bar means 41. Post 60 on the opposite side wall means can be similarly spaced from flange 54 on side wall means 50. Support posts 62 and 63 are located respectively at the rear corner junctions on the interior of the enclosure.
In accordance with the invention each of the support posts have means integrally formed on their upper ends for retaining, as well as supporting, shelf means 44, open framework means 46, or other similar structure. Projection 64 on post 60 and projection 66 on post 61 extend upwardly to define slot means 65 and 67, respectively, which extend in a direction parallel to the side walls. The rear corner posts 62 and 63 have retaining projections 68 and 69, respectively, which extend in angled relationship to the side walls to define curvilinear slot means 70 and 71 at these rear corner support stations.
The bottom wall means 49 of container module 30 includes contact surface means to position the con tainer module in accordance with the invention when disposed on a horizontal surface. As shown in FIGS. 10 through 12, in the unitary construction provided, this means takes the form of a pair of support and reinforcing ribs 73, 74 which support the container module on horizontal surface 75. Each rib is elongated and originates at a location adjacent to front flange 56 and terminates at a location contiguous to rear wall 52. Ribs 73, 74 are preferably spaced from the front-to-rear (longitudinal) centerline of the container module to provide stability but disposed inwardly of the respective side walls 50 and 51. In addition to providing a stable support surface, these ribs provide structural stength for the bottom wall means while reducing the material and weight requirements of such means.
Additionally, a bottom skirt means is provided for the container module. -As best seen in FIG. 7 the skirt means includes a front portion and a rear portion 81 which extends around the curvilinear junction of the side and rear wall means and terminates contiguous to a rearwardly projecting stabilizing means to be described in detail later. The bottom skirt is interrupted along each side wall by a recess handgrip opening such as 47.
An important aspect of the present invention for operating with a modular system is the ability to readily suspend a container module in upright position on a container support. The interconnecting means provided should not interfere with the full-open access features of the invention nor with means for lifting or handling the container module. Further advantages provided by the present invention are self-seating characteristics which enable the container module to be moved horizontally while in an upright position, that is without tilting, toward a support means and to be stably suspended by merely placing the container module on the support means without manipulation of any fastening or securing means. The container module should be readily removable from the upright support in a similar manner, that is without tilting to disengage or move away from the support rail means.
Details of interconnecting means 82 formed integrally with the container module are shown in the rear view of FIG. 7. The interconnecting means 82 includes a plurality of predeterminedly spaced elements which act to support the container module and stabilize the module against inadvertent dislodgement or lateral tilting when in suspended position.
The interconnecting means 82 includes elongated hanger means 84 extending horizontally across back wall means 52 at a location, selected for better stability to be above the lateral centerline, and preferably, contiguous to the chamfered edge of rear wall means 52. The elongated hanger means includes flange means 85 spaced from the rear wall means 52 by load support surface 86.
Stabilizing elements 88, 89 are in horizontally spaced locations selected to be below the lateral centerline for better stability, and preferably contiguous to the lower extremity of rear wall means 52.
Spacing between stabilizing elements 88, 89 is a distance greater than the length of the elongated hanger means 84 measured between internal confronting surfaces 90 and 91 which diverge in projecting outwardly from the rear container wall means 52. Stabilizing elements 88 and 89 project in the same direction as the elongated hanger means 84 from the rear wall means 52. This horizontal spacing between the inward ends of the stabilizing elements, at a location contiguous to rear wall means 52, is substantially equal to the distance between the lateral edges 32 and 34 of upright support means 31 shown in FIG. 1.
These stabilizing elements prevent lateral tilting of the container module. Further lateral stability is added by the elongated hanger means 84 in that side walls 92 and 93 of such hanger means, at a location contiguous to the rear wall means 52, are spaced substantially the same as side edges of the horizontally extended support slot means. Sides of the elongated hanger means 92, 93 taper toward each other in projecting outwardly from the rear wall means 52 to provide ease of insertion and, along with the stabilizing elements confronting surfaces 90, 91 help provide self-seating characteristics.
Rear wall means 52 includes reinforcing and surface contact means intermediate the hanger means 84 and stabilizing elements 88 and 89. These take the form of upright ribs 94 and 95 and lateral rib 96. These elements present coplanar surfaces for contacting the vertical upright support means so as to properly position the container module 31 in suspended position. As best seen in FIG. 8, the contact surface of reinforcing leg 95 contacts the upright support 31 so that the container module 30 is suspended in substantially upright position. The preferable construction of the container module when so positioned is to have the interior surface of bottom wall means 49 inclined slightly downwardly in approaching the rear wall means 52. Preferably the angle of inclination is about 2% degrees and extends from a location contiguous to the forward side of the container module to the rear wall.
The reinforcing leg means 73, 74 forming part of the bottom wall means are disposed to have their contact surfaces act in a similar manner when the container means is set on a horizontal surface, that is the interior surface of the bottom wall is inclined downwardly in approaching the rear of the container module.
Another important contribution of the invention results from the stable stacking features available with container modules as described. These include lateral and longitudinal stability stacking means. The stabilizing elements 88 and 89 of the unitary construction shown inn FIG. 7 provide an interlocking feature for stability in the direction leading from front to back of the container module. For this purpose an inverted U- shaped recess, such as 97 on stabilizing element 88, is provided at the base of each stabilizing element. The recess formed in each base of the stabilizing elements has an outwardly sloping rear surface 98 and a load bearing surface 99. The outwardly sloping surface 98 coacts with the chamfered surface on the top periphery of each container module and provides self-seating characteristics.
For lateral stability, stacking grooves are provided at the forward upper edges of the container module. Stacking grooves 103 and 105 are best seen in FIG. 11. Projections 107 and 108 at the lower forward edge of a standard container module interfit with slots 103 and 105, respectively. These slots and projections are formed to have conforming configurations and self seating characteristics.
Container module 30 is of unitary construction and is modled or cast from a plastic material such as structural foam. High density polyethylene, high-impact polystyrene, and polypropylene are suitable examples. A specific example is the NORYL type of structural foam available from General Electric Co., Plastics Department, Selkirk, N.Y. NORYL FN 215 is preferred for its fire safety characteristics. The plastic material is selected to have a high softening temperature so it can be cleaned and/or at least toxic gas sterilized without deteriorating. Corner junctions of the enclosure are rounded to avoid sharp inside and outside corners for ease of cleaning.
The rear wall means 52 of the container module 30 has excellent beam strength as a result of vertical ribs 94, which project from rear wall means 52. Such rib means provide the required strength while saving mate rial and weight by permitting reduced wall thickness intermediate such ribs. The bottom wall means 49 is strengthened and made more rigid as a result of the beam strength obtained from support and reinforcing ribs 73, 74.
THE COVER Cover means 39, shown in FIGS. 2 and 3 is formed from a single sheet of transparent vinyl or polystyrene, of about 25 mil thickness to provide required flexibility by known vacuum forming techniques. Cover means 39 includes a generally rectangular upper portion 110 and a generally rectangular front portion 111. Upper portion 110 includes a flat panel 112 bordered by a rib wall 113 in angled relation to panel 112. Located peripherally to rib wall 113 is narrow-width horizontally disposed surface 114 extending around the full periphery of upper cover portion 110. Depending from the peripheral horizontal surface 114, along side wall and rear wall portions, is downwardly inclined skirt means 115. This skirt means extends around side wall and rear edges of upper cover portion 110. A beading 116 can be added to the bottom edge of skirt to add strength to the skirt means.
Front cover portion 111 is joined to upper cover portion 110 along unitary hinge juncture 117. The front cover portion 111 includes peripheral flange 118 which extends around recessed portion 119. The recess portion 119 includes panel wall 120 joined to flange 118 by an inwardly projecting rib wall 121.
Centrally located along the lower flange portion 122 of the front cover means 111 is lift tab means 123 including an elongated rectilinear recess 124. As shown in FIG. 13, the lower extremity of flange 56 of container module 30 is provided with an inverted L-shaped notch 125. On the cover means 39 the upper wall 126 of tab recess 124 has a projecting bead 127 at its inner end which snap locks into the inverted L-shaped recess 125.
The coaction of cover means 39 and container module 30 in closing and sealing the access openings are described in detail in applicants copending application entitled Self-Seating Container Module Cover. How ever briefly, a double seal arrangement is provided around all peripheries with horizontally disposed peripheral border 114 contacting the upper horizontal surface 57 of the container module and the skirt means 115 contacting the chamfered surface 58 extending around the upper periphery of the container module. On the front cover portion 111 of cover means 39 the planar border around side and bottom edges contacts the flanges 53, 54 and 55 around the front end of the container module. Rib wall 121 contacts an inwardly inclined edge along the side walls 54 and 55 and across the front of the bottom wall means 49.
To close container module 30 with cover means 39 it is merely necessary to seat the upper cover portion 110 with self-seating characteristics being provided by the skirt means 115. When the front cover portion 111 is lowered and snapped into position a double seal is provided around all peripheries of the fully open accesses to the enclosure. The rib walls 113 and 121 add rigidity to the cover means but other reinforcing lines can be used across the planar panel means without departing from the teachings of the invention.
THE RETAINING BAR The removable retaining means 41 of FIG. 4 is shown in greater detail in FIG. 14. Retaining means 41 in effect acts as a front partition and can be molded or cast in plastic. Preferably, retainer means 41 is fabricated from a single piece of sheet metal bent to provide a top wall 130 and side walls 131 and 132. Bottom edges of side walls 131, 132 are spaced above the lower extremity of the retainer means 41. As shown, bottom edge 133 of side wall 131 is inclined downwardly in approaching front wall 134 and facilitates insertion of the retainer means.
Top wall 130 projects from front wall 134 the same distance as side walls 131 and 132; these walls project a distance slightly less than the distance between the rear surfaces of flanges 54 and 55 (FIG. 8) and a front surface of front posts 60 and 61. This permits retaining means 41 to slide between flanges 54, 55 and posts 60 and 61 into the position shown at FIG. 8 and to be held firmly in upright position. FIGS. 4 and 8 also show that the retaining bar 41 has a vertical height less than the height of the shelf support posts. Shelf or basket means can be positioned above the retainer means 41.
SHELF AND PARTITION ARRANGEMENT The removable shelf means 44 of FIG. 5, is shown in greater detail in FIGS. through 17. Shelf means 44 is molded or cast from suitable plastic material or fabricated from a single sheet of sheet metal to provide a top wall 140, a front wall 141, side walls 142 and 143, a rear wall 144, and rear corner tabs 145 and 146. These walls and tabs each project perpendicularly from the edges of top wall 140. Tabs 145 and 146 are angled, at approximately 45, between rear wall 144 and side walls 142, 143, respectively. Tabs 145 and 146 interlock with the slots 70, 71 (FIG. 9) formed by projections 68, 69, on the rear corner support posts 62, 63. Side walls 142, 143 of the shelf means 44 interlock with slots 65, 67 formed by projections 64, 66 on the front cover support posts 60, 61. The height of each wall and tab of the shelf means 46 is substantially the same as the height of the corner post projections so that the shelf will be firmly supported by the slots and the projections at each of the support posts 60-63. The shelf means 44, when in place, is locked against both longitudinal (rear to front) movement and lateral movement.
As shown in FIG. 17, front wall 141 is slightly longer vertically than the side walls and provides additional longitudinal stability through contact with flanges 54, 55 of the container module side wall means. All walls depend without forming enclosures to facilitate cleaning. Six pairs of spaced openings 150 through (FIG. 15) provide a plurality of partitioning arrangements, e.g., in halves or thirds. Each opening is elongated in a direction parallel to side walls 142, 143 and extends completely through the shelf means. The openings of the respective pairs 150, 151, 152 are offset toward rear wall 144 and the openings 153, 154, 155 are offset toward front wall 141. The respective openings of each pair are aligned with each other in a fore and aft direction on the shelf.
The blank from which partition means 45 is formed is shown in FIG. 18. Blank 158 is generally rectangular and has a pair of locking tabs 159 and 160 which project downwardly from a bottom edge 161 of the partition. Locking tabs 159 and 160 have the same height as stabilizing legs 162 and 163. Stabilizing legs 162 and 163 each have their respective end edges 164 and 165 in spaced relation to the tabs. Stabilizing legs 162 and 163 are separated by a rectangular slot 166. Stabilizing leg 162 is bent laterally along bend line 167 while stabilizing leg 163 is bent laterally in an opposite direction along bend line 167. This provides the partition structure shown in FIGS. 5 and 19 where leg 162 extends to the left of body 168 and perpendicular to the plane of the body and leg 163 extends to the right of body 168.
The length of each of the latch tabs 159 and 160 where unitary with the main body portion of blank 168 is slightly less than the length of each shelf opening. The distance between a rear edge 170 of tab 159 to the tip 171 of tab 160 is slightly greater than the length of the shelf openings 156 so tabs 159 and 160 enter aligned shelf openings in angled relationship to the horizontal to mount the partition on the shelf. The partition is preferably mounted on the shelf with tabs 159 and 160 facing toward rear wall 144 of the shelf; the partition is dimensioned so that after the tabs are inserted through a selected pair of aligned openings, the partition is then moved in a direction toward rear wall 144 of the shelf. Rear edge 172 of the partition is flush with rear wall 144 of the shelf and contiguous to rear wall means 52 of the container means which prevents accidental dislodgement of the partition. The distance between a top edge 174 and blank edge 161 is approximately the same as the thickness of the sheet metal of shelf means 44 so that the partition is rigidly held on the shelf means against up and down movement. In addition, legs 162 and 163 extending in opposite directions to engage the upper surface of top wall 140 of the shelf means prevents tilting and adds vertical and horizontal stability.
The principle of the partition support can be used on an apertured partition support at the rear wall. Such partition support includes a flange means which is positioned in slot means 70, 71 at the rear support posts 62, 63 and is held by protrusions 68, 69. Vertically oriented partitioning blank means, extending parallel to side walls are attached to the rear wall located partition support. Such dividers can extend either the full height or a portion of the height of the enclosure. Lock tabs and stabilizing legs are located on the rear vertical leg of the partitioning means rather than along a bottom leg as in the shelf supported partition of FIG. 18 but operate in a substantially identical manner with tabs inserted in the slots and supports.
Wire basket 46 of FIG. 6 has a top rim 180 which extends around three sides of the basket and which has a length along the respective walls of the container module which is only slightly less than the inside dimensions of the enclosure so the basket can be supported in a manner similar to shelf means 44. Corner portions of the basket are open as shown in FIG. 6 to enable seating in the slots of the cover support posts.
UPRIGI-IT SUSPENSION Vertical support means 31 on which container module 30 is suspended in cantilever fashion is formed from sheet metal and is hung in an upright position on walls or mobile carriers, or pole mounted. Details of this structure and mounting are covered in applicants copending application entitled Modular Storage, Transfer Handling and Retrieval System. However, support 31 is generally rectangular in cross section and presents a plurality of horizontally elongated vertically aligned amd spaced hanger slots such as 190 of FIG. 8. Openings such as 190 are formed in a vertically elongated planar surface 191. Along the bottom edge of each opening is a rearwardly bent horizontal ledge 193 terminating at a downwardly bent vertical wall 194. Upright support 31 also has side walls 33 and 34 (FIG. 9) along its lateral edges.
With container module 30 positioned on support 31 as shown in FIGS. 8 and 9, hanger bar 84 extends through opening 190 with flange 84 engaging rear vertical wall 194. Confronting faces 90, 91 of stabilizing projections 88, 89, respectively, are contiguous to the outside surfaces of the respective side walls 33 and 34 when the rear surface ribs 94 and 95 are flat against upright surface 191 of the support surface 31. Through the previously described interaction of hanger means 84 and stabilizing elements 88, 89, container module 30 is stably suspended on upright support 31 and held by gravity.
