Kalamazoo, Mich., a corporation of Michigan Filed Nov. 21 1966, Ser. No. 595,878 Claims. (Cl. 211-90) ABSTRACT OF THE DISCLOSURE This invention relates in general to a storage unit and, more particularly, to a type thereof comprising an articlesupporting deck and means for removably mounting said deck upon upright wall means. In this embodiment, the storage unit is fabricated substantially completely from metal parts, the majority of which are rod form. The unit comprises a deck having a plurality of spaced crossrods supported upon spaced lengthwise rods, the rear one of which is mounted upon an upright wall by rear brackets which preferably permit pivotal movement of the deck around its rearward edge at least between a substantially horizontal position and a substantially vertical position depending from the rearward edge of the deck. The frontward edge portion of the deck is supported upon and between front brackets which are either mounted upon an adjacent side wall or upon the frontward end of a frontward projection on the rear bracket. In one form, the front brackets can be easily disconnected from the deck to permit pivotal movement of the deck in installations where such movement is desired. Alternatively, the same front brackets can be fixedly attached to the deck so that disconnection requires damage to or distortion of the connecting parts, whereby the unit is theftproof.
In a modified form of the invention, the front and rear brackets are arranged so that the shelf deck can be quickly and easily removed from the wall structure upon which it is normally mounted. However, by a minor modification involving the addition of relatively minor parts to the brackets, the same deck can be rendered incapable of movement from a fixed position so that it is theftproof.
The problems of providing adequate storage space are well known and ever present. Many attempts have been made to develop improved storage units and one such device is disclosed in copending patent application Ser. No. 550,401, filed May 16, 1966. However, in the course of commercializing this earlier storage unit, it was found that other problems existed which had not been overcome. For example, shelves which can be easil and quickly detached from their mounting brackets for the purpose of cleaning and/or redecorating, are readily susceptible to theft. Thus, while such storage units are completely adequate for installation and use in private dwellings, they are not desirable in commercial installations.
On the other hand, even though a storage unit, such as shelving, is fabricated so that it can be installed theftproof, it is generally desirable to construct and install the shelving so that it can be moved, or at least repositioned, when the need arises.
It has also been found that in commercial installations, it is highly desirable to have all hardware installed after the completion of the construction work and with a minimum amount of installation cost, such as that arising out of the services of skilled artisans, required to make adjustments in the basic structure in order to receive the hardware. For example, where purchased finished storage units are to be installed, it is desirable that all of the preliminary arrangements for such installations can be ice completed by the contractor prior to delivery of the purchased finished items which can then be installed after the regular construction workmen have departed the premises.
However, it has been found that many types of storage units, such as shelving, must be installed by the workman during the final stages of the actual construction of the building or the resulting installation of the units will be unacceptable to the proprietors of the building. That is, it has been practically impossible to install the shelving units, for example, on preinstalled brackets and supports without making a great many adjustments in the positions of said brackets and supports, during the installation of the shelving decks.
Accordingly, the objects and purposes of this invention have been to provide a storage unit, and particularly an article-supporting shelf structure, which:
' (1) Can have all of its supporting brackets and hardware installed in advance of the installation of the shelving deck, thereb simplifying the completion and decoration of the building prior to the final installation of the shelving deck;
(2) Is designed so that it can be alternatively installed theftproof or removable, thereby adapting it for both commercial and residential use with a minimum of variations in its basic and principal components;
(3) Is capable of installation so that the deck can be easily moved between a normal article-supporting position and a second position which facilitates redecorating of the wall space adjacent thereto, but which still prevents easy theft of the shelf structure;
(4) Is capable of being installed in preselected lengths which do not have to be exact and which include adjustment features permitting adaptation of the shelf to a substantial variation in the space dimensions and the locations of preinstalled brackets without adversely affecting the performance of the shelving unit;
(5) Is fabricated in modular sizes which can be adapted to any space requirements, which is extremely sturdy in construction, easy to maintain and attractive in appearance.

The terms inner, outer and derivatives thereof Will have reference to the geometric center of said storage unit and parts thereof.
Descripti n The objects and purposes of the invention, including those set forth above, have been met by providing an article-supporting device or storage unit 10, a preferred embodiment of which is illustrated in FIGURE 1. Said storage unit is comprised of a deck 11 which is supported by rear brackets 12 and 13, which are attached to an upright wall 20, and by front brackets 14 and 15 which are attached to the rear bracket 12 and said wall 20, respectively. Although the following description of the invention is in terms of structure made largely from rod-form materials, it should be realized that other types of construction could be used.
The deck 11 is comprised of a plurality of preferably evenly spaced parallel crossrods 16 which extend transversely of and are secured, as by welding, to two or more lengthwise rods, such as the rods 17, 18 and 21. The front rod 21 is seucred to a hanger bar 19 by a plurality of truss members 22, which extend between said rods and are secured thereto, as by welding.
Each truss member 22 (FIGURES 2, 3 and 4) is channel shaped and has a pair of flanges 24 and 26, and a web 2 For aesthetic, as well as utilitarian purposes, said flanges may have an elliptical shape. A portion at each end of web 27 may be removed and an opening 28 may be provided in the center of said Web to permit easy draining when the deck is coated. The flanges 24 and 26, have coaxial openings 29 and 31, respectively, through which a latch member or pin 32 may be slideably received.
The rear lengthwise rod 17 of the deck 11 is supportedly engaged by rear brackets 12 and 13 which may be provided with various constructions, as shown. For example, rear bracket 12 (FIGURE 1) is comprised of an upright bar 33 having a frontwardly offset portion 35 which defines with the wall a transverse opening 34 into which one end of the rear rod 17 may be inserted. Said bar 33 may be fastened to the upright wall 20 by conventional means, such as screws 36.
The other rear bracket 13 (FIGURE -6 may be formed of strap material which is bent to form an opening 31 into which the other end of rod 17 may be inserted. The ends 37 and 38 of said bracket 13 have aligned openings 39 so that the bracket may be secured to the wall 20 by conventional means, such as the screw 42. Rear bracket 13 is of a type which may be positioned at a plurality of closely spaced locations along the rear rod 17, simply by spreading apart the two ends 37 and 38 of the strap and inserting rod 17 therebetween until it seats in the opening 31.
When the deck 11 is connected to the wall 20 by rear brackets 12 and 13, only, said deck may be pivoted upwardly and downwardly around the axis of the rear rod 17.
Front brackets 14 and 15 may be of various types, as long as they have an opening into which a latch pin may be supportedly received. The front bracket 14, for example, may be of a type (FIGURES 1 and 5) which is integral with, and a forward extension of, the rear bracket 12. Said front bracket 14 is comprised of a pair of arms 45 and 46 (FIGURE 1) which are preferably integral with the bar 33 and converge frontwardly therefrom where they are connected to boss 47 having a pin opening 44 (FIGURE 5).
The latch pin 32A, which has a head 43, extends through the opening 44 in the boss 47 and through the openings 29 and 31 in the flanges 24 and 26.
The front bracket 15 is preferably utilized where there is an adjacent wall 20 to which said bracket 15 may be secured. The opposite ends of the bracket 15 are secured to wall 29 by conventional means, such as screws '50. Bracket 15 (FIGURE 4) may be formed from strap material and has a central offset portion 48 with a transverse opening 49 for reception of latch pin 32. The latch pin 32 is slideably disposed in the openings 29 and 31 of the truss member 22 adjacent the front bracket 15 and in the opening 49 of the bracket 15 for normal support.
The brackets 12, 13, 14 and 15 may be fabricated from metal or plastic material. The latch pin 32 has an offset portion 40 which facilitates alignment thereof with the opening 49 in bracket 15.
Latch pin 32 (FIGURE 2) may be releasably, but securely, held in position in holes 29, 31 and 49 by lock spring 51, which is disposed between the flanges 24 and 26. Said spring has a pair of coils 52 and 53 through which pin 32 extends, and said coils are connected by an elongated, U-shaped portion 54 which projects rearwardly of the truss member 22 for manual engagement. Said coils 52 and 53 have projections 55 and 56, respectively, extending laterally therefrom (FIGURE 3) for locking engagement in notches 57 and 58 (FIGURES 3 and 4) of the flanges 24 and 26, respectively. To effect lengthwise movement of said pin 32, the elongated portion 54 is forced in a clockwise direction (FIGURE 3) from its solid line position to its broken line position 54A, while said projections are secured in said notches, thereby causing coils 52 and 53 to expand. While the spring 51 is retained in such position, pin 32 may be rotated or moved axially through openings 29 and 31, coils 52 and 53 and opening 49. When said spring 51 is released, coils 52 and 53 contract, thereby gripping the surface of said pin and preventing its accidental movement with respect to the truss 22 in which it is supported.
Modification The above-described storage unit 10 is well suited for installation in private dwellings or closely controlled commercial buildings where there is little concern about theft. However, with minor modification, the storage unit 10 can be adapted for use in commercial and industrial installations where it is especially desirable to provide a unit which is theftproof.
As shown in FIGURE 7, the front bracket 15 is replaced With a front bracket 59 which can be flush with and recessed into the plastered wall 20. Bracket 59 is preferably cup-shaped and has a lip 62 which may rest against the surface of the wall 20. Said bracket has a recess 61, the dimensions of which are such that the offset end 40 of latch pin 32 may be inserted therein. Being plastered into the wall, bracket 59 is inconspicuous when not in use and is not readily removable. Bracket 59 may be molded of a suitable material, such as metal or plastic. The latch pin 32 is firmly held (hence theftproof) in the recess 61 in bracket 59 by the self-locking washer which is pressed tightly against the adjacent flange 26 of the truss member, when the pin 32 is properly disposed in said recess 61. Thus, to remove the deck 11 from the bracket 59, it is first necessary to overpower the lock washer 60.
FIGURES 10 through 13 illustrate an alternate rear bracket 63 which permits quick and easy release of the deck 11 from support thereby, but which can be readily made theftproof by adding the element disclosed in FIG- URE 15.
The rear bracket 63, which may be positioned at substantially any location along the rear of deck 11, is comprised of a U-shaped wire hanger 64 and a channel-shaped member 65. Holes 67 and 68 are provided in the backplate 66 of said member 65 through which screws 75 may be inserted to fasten said bracket 63 to an upright wall 20.
The U-shaped, wire hanger 64 (FIGURE 14) is in fact comprised of two outer, U-shaped elements 85 and 86 which are spaced from each other, substantially parallel and interconnected at one end of each by the arcuate portion 87. The U-shaped member 64 also includes a pair of inner U-shaped elements 88 and 89 which are integral with and disposed radially inwardly of the outer U-shaped elements 85 and 86, respectively, for engagement with the rod 17, as shown in FIGURE 10.
Since the wire hanger 64 is preferably fabricated from a single piece of spring wire, and since the inner elements 88 and 89 are spaced from the outer elements 85 and 86, the hanger 64 can engage and properly support the rod 17 in a substantial number of relative positions be tween the rod 17 and the mounting member 65, as shown by the broken line position 17A of the rod 17 in FIGURE 10. Accordingly, minor misalignment of the mounting member 65 during its installation will not affect its performance. Moreover, minor irregularities in the surface of the wall can also be absorbed by the described structure of the wire hanger 64.
The backplate 66 has a transverse and substantially horizontal offset portion 70 through which the legs 91 and 92 of the outer elements 85 and 86 may be inserted to help anchor the hanger 64 upon the mounting member 65. One of the screws 75 (as shown in FIGURE 11) extends between the legs 91 and 92 adjacent the arcuate portion 87 to complete the anchoring of the hanger 64 upon the mounting member 65. However, the spacing of legs 91 and 92, and the length of the offset portion 70 are such that the inner elements 88 and 89 can move axially of the rear rod 17 for the purpose of avoiding interference from the crossrods 16 in the event that one of said rods is located close to or in front of a preinstalled bracket 63.
With bracket 63 secured to the wall 20, the rod 17 of deck 11 (FIGURE may rest in the upwardly opening recesses of the U-shaped elements 88 and 89. As indicated in FIGURE 11, the front ends of the elements 88 and 89 extend slightly above the centerline of the rod 17 and hook rearwardly to clamp the rod 17 against the front edges of the flanges 93 and 94 on the mounting member 65, whereby accidental disengagement is yieldingly resisted.
The bracket 63 (FIGURES 12 and 13) may be adapted for theftproof amendment to the rear lengthwise rod 17 by means of the U-shaped lock member 69 (FIGURE Said lock member 69 has a pair of hooks 71 and 72 on its legs 96 and 97, respectively, which are hooked over rod 17, after the rod is held by the bracket 63 on said wall. The bight 98 is adjusted downwardly until it can be moved into the notches 73 in the lower edges of the flanges 93 and 94. Wire hanger 64 and lock member 69 are made of material that is sufliciently resilient that rod 17 may be adjusted into place even though the rear bracket 63 has been secured to the wall in advance.
The alternate locking member 76 (FIGURES 8 and 9) is V-shaped and has flanges 77 and 79. The flange 77 has a circular hole 78, the diameter of which is slightly larger than the diameter of pin 32. Flange 79 has a slightly ovalshaped hole 81, which has its major axis lengthwise of the flange. To move the pin 32 lengthwise into or through the locking member 76, the flanges 77 and 78 must be squeezed together as illustrated by the dotted lines in FIGURE 9. When said flanges are released they move apart and thereby grip the pin 32. Locking member 76 is preferably made of spring steel. In this embodiment, the deck 80 comprises a perforate sheet, which may be metal, wood or plastic, and which is mounted upon lengthwise rods 83.
It will be evident from the foregoing descriptive material that a variety of ditferent deck or shelf constructions can be used and that they may be supported upon upright wall means by brackets according to the invention, including the rear brackets 63 and front brackets 14 and 15.
The deck 11 (FIGURE 3) is disclosed as having its front edge directly above the hanger bar 19, However, it will be recognized that the crossbars 16 can extend forwardly of the hanger bar 19, hence the front rod 21, as indicated in broken lines at 16A. Under such circumstances, it may be desirable to provide a further truss member 22 at both ends of the extended frontward edge of the deck with a corresponding pin 32 for the purpose of supporting the extended frontward edge of the deck upon the upright wall. The offset outer end portion 40 (FIGURE 2) of the pin 32 permits normal insertion of the pin into the opening in the bracket or an opening in the wall by which the support is achieved. Moreover, normal irregularities in the runout of the wall or the locations of brackets or openings in the wall do not require change or modification in order to effect completely satisfactory installation and support of the storage unit.
In fact, installation of the storage unit as it is normally thought of in the building trade, wherein the brackets are all mounted after the interior is finished, is not required for this storage unit. Furthermore, it is unnecessary to make the considerable adjustments often required to adapt the deck structure to the preinstalled brackets or openings. The decks are merely mounted upon the brackets and the aforementioned structure permits such mounting without the use of any tools or special instructions.
Where it becomes desirable to have intermediate support lengthwise of the shelf deck, such is accomplished by using two decks 11 and placing them in abutting relationship on opposite sides of a rear bracket 12. In such case, the pin 32A (FIGURE 5) may be replaced by a single pin Which extends completely through a pair of trusses located at the abutting ends of the decks, hence, on opposite sides of the front boss 47 of the bracket 12. Alternatively, if it is desirable to provide an offset portion in the pin, for reasons described above, the boss 47 may be made somewhat oversized so that two pins having 0&- set portions may be used whereby such otfset portions can enter the opening in the boss 47 from opposite sides thereof.
While a truss member 22 is shown near the center of the hanger bar 19 for the purpose of supporting same upon the front rod 21, it will be recognized that this truss member may be replaced by one of the oval-shaped truss elements 99 which also extend between and are rigidly secured to the bar 19 and rod 21.
Although particular, preferred embodiments of the invention have been described above in detail for illustrative purposes, it will be recognized that variations or modifications of such disclosure, which lie within the scope of the appended claims, are fully contemplated.
