Wallace, Bradfordwoods, Pa., assignor to The Brad-Mar Corporation, Wexford, Pa., a corporation of Pennsylvania Filed Jan. 11, 1965, Ser. No. 424,776 15 Claims. '(Cl. 211-44) This invention relates to a display and utility rack and particularly, to a rack suitable for compactly and effectively displaying bolts of cloth material and for efficiently utilizing the bolts. A phase of my invention deals with a new and improved holder for supporting a cloth bolt in an upright position, for manipulating and tilting it, and for inserting and removing it.
My invention particularly deals with means for supporting, displaying and utilizing bolts of cloth material that are of somewhat flat of oblong shape. The cloth bolts are wound on a central mandrel of flattened or oblong shape which serves as a central core and may be of any suitable material, such as cardboard, wood, resin, etc.
The material of the bolts is customarily folded in half and wrapped around the mandrel. The cloth is supplied in various more or less standard widths of 18 inches, 24 inches, 30 inches and 36 inches, such that, as folded, it provides a bolt width of 9, 12, etc., inches. The Width becomes the height of the bolt when it is stored or displayed in an upright position. It will be appreciated that a bolt will have a considerable thickness when newly supplied and that it will be decreased in thickness as material is cut off and sold; this results in a variation in the space required for storing or displaying it.
A yard goods merchant finds it necessary to make the most efficient use of available space, in order that a desired full-line of materials will not only be available to the customer, but will also be attractively displayed for the customers inspection. This has to be done in such a manner as to permit movement between the racks, cleaning under the racks, a maximized elfective utilization of floor space and of head room representing the normal vision of a customer, and a minimized use of overhead room to provide suflicient light and to enable a clerk to look over the racks to see the customer. Generally speaking, the display should be such that a customer and clerk of average height can see over the top of the material display rack.
It has been an object of my invention to provide a new and improved form of display and utility rack that has modular flexibility, and that makes maximum utilization of available display space and in the most effective manner;
Another object has been to devise a display rack that is readily adaptable to different widths or heights of bolts as well as thicknesses of material thereon, and that will make possible the use of display shelves along sides as well as ends of the rack;
Another object has been to provide a display and utility rack for cloth bolts in which upper and lower tiers or layers of bolts may be in a closely adjacent or above and 'below relationship, and each bolt can be readily inserted and removed as well as inspected while being supported on the rack;
Another object of my invention has been to provide a new and improved form of display and utility rack for cloth bolts which will accomplish a stable retention of the bolt in an upright stored position there-on and, at the same time, will permit the bolt to be swung outwardly on an arc and suppored at an outwardly-inclined relationship for inspection and, when swung out, will permit the bolt to be easily removed and inserted on a holder;
A still further object of my invention has been to devise a new and improved form of bolt holder for a display and utility rack which is flexible in its utilization and which provides a two-position support of the bolt;
A still further object of my invention has been to devise bolt holders for rack shelves which will be slidable there-on to accommodate diiferent thicknesses of cloth bolts and which can be readily removed from and inserted on the shelf at any position therealong;
These and other objects of my invention will appear to those skilled in the art from the illustrated embodiments and the appended claims.

FIGURE 8 is a partially broken-away perspective view on the scale of FIGURE 7, illustrating how the holder of FIGURE 7 is inserted for positioning a bolt of cloth material.
In carrying out my invention, I make use of frame members in constructing a rack which may be readily shipped in a knocked-down compact package form and readily assembled to provide a strong and rigid support for a large number of cloth bolts. The frame members are provided with latching slots in a spaced relation along their vertical extent to detachably-receive outwardly-projecting bolt supporting shelves. Each shelf is provided with a suitable number of upwardly-projecting bolt holders which are detachably-mounted thereon for slid- :able movement longitudinally therealong. I preferably utilize a longitudinally-extending cross member on a rack of my construction to provide a back support or rest for a line of cloth bolts. The cross member is located in a spaced relation above and back of a particular shelf on which bolts are to be positioned in a vertically-upwardly extending relation thereon. This contributes to the stability of the bolts in their normally fully vertical upright positioning on a given shelf and on an associated holder.
Referring particularly to the rack embodiment 10 of FIGURE 1 of the drawings, it will be seen that I have provided two rectangular skeletonized frames 11, and a skeletonized-rectangular, cross-extending, central or mid-frame 13. Each end frame 11 has a pair of transversely-spaced-apart vertically-extending upright memhers 11a and 1112, an end connecting top bar or rail member 11c, and an upwardly-spaced lower connecting bar or rail member 11d. Members of the frames 11 are, like members of the frame 13 and members of shelf frames 15 and 15', shown of hollow rectangular or boxlike section to provide strength and rigidity with a minimization of weight, see particularly FIGURE 2.
Referring again to FIGURE 1, the central or midframe 13 is provided with longitudinally spaced-apart upwardly-extending or vertical upright members 13a and 131), a top end connecting bar or rail member 130, and a bottom end connecting bar or rail member 13a, as well as an intermediate connecting bar or rail member 13d. Like the end frames 11, the cross or central frame 13 is of integral construction as to its members, as by welding or brazing the members together into an integral structure, if the frames are of metal construction, If the members are of resin construction, they may be formed integrally or cemented together into an integral structure. Bottom portions of the end frames 11 serve as legs for the rack and may either receive rolling casters, such as 12 of FIGURE 1, or plug-fitting slides, such as 27 of FIGURES and 6.
In the construction of FIGURE 1, I have illustrated a display and utility rack that is suitable for carrying two tiers of cloth bolts along its opposed sides as well as along its ends. For simplicity of illustration, I have only shown end shelves at one end of the rack. Side shelves 15 are of unitary rectangular construction, as made-up of longitudinally-extending, spaced-apart parallel, front and back bar or rail members 15a and 15b, a central cross member 15c, and end-connecting or support members 16 of somewhat wing-like shape. As shown in FIGURE 3, the front and back members 15a and 15b lie on a common plane to support cloth bolts 18 in upright positions thereon. As shown particularly in FIG- URE 2, each 'Wing end member 16 has an upper latchpivot type of tongue or lug 16a and a pair of verticallyspaced straight type of tongues or lugs 16b that are adapted to fit within adjacent side slits or slots a that are vertically-spaced along mid frame vertical upright members 13a and 13b. It will thus be apparent that the shelves 15 may be easily inserted and removed at desired heights along the frame members. End shelves 15' are of the same construction as the side shelves 15, except that, due to their shorter lengths, they are not provided with cross brace members 15c. Their front and back bar or rail members 15'a and 15b are secured at their ends to wing or end connecting members 16. The members 16 have tongues or lugs corresponding to the lugs 16a and 16b of the members 16, and are adaped to removablyfit within adjacent horizontally-aligned slots b along the vertical extent of the vertical upright members 11a and 11b of the end frames 11.
As shown in FIGURE 1, when the rack 10 is shipped to a customer, it can be then easily assembled by inserting threaded bolts 14 through members 11d and 110 of the end frames 11 into threaded bore portions of vertical upright members 13a and 13b of the mid frame 13.
As illustrated in FIGURES l and 2, I have provided upright holders for supporting bolts of cloth material, such as 18 of FIGURE 8. Each holder 20 has a vertical front leg portion 20a connected at its upper end by a narrow loop portion 20b to a backwardly-downwardly-outwardly declining or forwardly-upwardly-inwardly-inclined back leg portion 20c. The leg portions of the holder 20 are preferably of flexible material, such as of metal or resin wire or rod construction, and are at least connected by a flexible portion 20b. Each holder 20 is provided with front and back slide mount or foot portions 20d and 20e that are shaped to fit on the bars 15a and 15b or 15'a and 15'b. The foot portions 20d and 20e are secured to lower ends of the legs 20a and 200, are of concave, channel-like or rectangular shape so as to slidably-fit in a complementary manner on or about three sides (top, front or back, and bottom) of associated shelf bar members 15a and 15a or 15b and 15'b. Each holder 20 is pre-stressed to normally flexibily-tension its leg portions, in order that the feet will normally be flexiblyclamped or retained in a frictionably-slidable position on 4 the shelf bar members. As shown in FIGURE 7, the tensioning may be such as to move the legs towards each other or to flexibily-resist spreading them apart or outwardly with respect to each other. It will be noted that the feet 20d and 20s have an open side, shown as an inwardly-open side in FIGURE 2, so that the holder 20 may be inserted on and removed from the bars 15a and 15b by manually flexing the leg portions 20a and 200, to spread them apart or outwardly against spring tension. As shown, the feet of each holder 20 have opposed inwardly-open sides.
As particularly illustrated in FIGURE 2, each holder 20, when viewed from the front has a fully forwardlyupwardly-sloped back leg 20c and a fully vertically-extending front leg 20a to define a triangular shape that represents a half of a rectangle, bisected by the leg 20c as a diagonal. It will be apparent that each holder 20 may be removed and inserted at any position along the length of a particular shelf 15 or 15 by merely expanding its legs 20a and 200 outwardly with respect to each other, and then releasing them to permit them to slidably-clamp on slide bars 15a and 15b or 15a and 15'b.
In FIGURE 3, I have illustrated a utilization of a rack structure, such as shown in FIGURE 1. The solid line position B shows a bolt of material 18 as tilted outwardly by a clerk or customer, and as supported in an outwardlyinclined relation on the back leg portion 20c for inspection. The solid line position A shows the bolts 18 in their normal upright supported positions, resting against back rail members and 13d, as compared to position B. The dot and dash line position C shows how a bolt 18 is endwise-removed from and inserted on a holder 20 from the tilted-out position B. FIGURE 7 shows the leg portions as spread-apart for mounting and removing the holder 20 which is greater than the distance between the front and back shelf bars 15a and 15b (see the dot and dash position of the leg portions 20a). It will be noted that the normal free closed-in relation of the leg portions is less in spacing than the distance between the front and back shelf bars, such that the legs are flexibly-tensioned towards each other in the full line position of FIGURE 7. Incidentally, referring to FIGURE 8, the holder 20 is inserted between the inside of the inner layer 18a of the cloth of the bolt and its mandrel 19.
The embodiments of FIGURES 4 and 5 show the adapt-ability of my invention. In FIGURE 4, the shelf 15 is mounted on a pair of longitudinally-spaced-apart forwardly-slotted vertical members 21 which are secured to the wall, as by bolts 22, and which have at least one cross connecting rail member 23 in a spaced relation above the shelf 15. In FIGURES 5 and 6, I have shown a triangular or substantially A-shaped rack 25 that employs hollow box-like, rectangular front and back frames 26 and 26' of similar construction whose parts have the same numbers, but with the parts of the back frame 26' designated by prime afixes. The front frame 26 is made up of spaced vertical or upright members 26a and verticallyspaced cross bar or horizontal rail members 26b and 260. The members 26a are provided with front slots a along their outer sides to removably-receive shelves 15". The shelf 15" may be of the same general construction as the shelves 15 and 15', except that the back end edge of each of its spaced pair of end wings 16" inclines forwardlydownwardly to correspond to the inclination of the support frame. In FIGURE 5, if the frame 26 inclines about 13, then the back edge which carries the latching lugs (corresponding to 16a and 16b of FIGURE 2) will also slope about 13.
It will be noted that where, as shown in FIGURE 5, the frames 26 and 26 have an off-vertical inclination, the shelves 15 have a horizontally-offset positioning. This enables the cloth bolts 18 to be positioned endwise on a vertical plane for better display and in such a manner that loose folds of an upper tier of cloth bolts will not drape over the cloth bolts of a lower tier.
her as on the front frame 26.
The cross member 26b serves as a top end connecting member and the member 26c serves as an intermediate connecting member for the front frame 26; such members serve to connect the vertical members 26a and to reinforce the frame. The back frame 26' is shown provided with corresponding box-like or hollow rectangular cross members 26'b and 26'0.
The upper end of the back frame 26' is provided with a pair of outwardly-projecting side-strap members 28 which are integrally secured thereto, as by weld metal w, and which are pivotally secured to the front frame 26 by bolts or bolt and nut assemblies 29. It will be apparent that the front and back frames 26 and 26 may then be folded in shipping and in storing to a substantially abutting parallel relation with each other. A pair of removable connecting arms 30 are provided in a spaced relation above the lower ends of the frames 26 and 26 and are secured in position by bolts or bolt and nut assemblies 31 to provide the desired angular relation or slope between the back frames. I preferably provide a backward slope fom the vertical for the frames 26 and 26 of about 13. I also prefer to make the shelves of shorter outward width or outward extent than the shelves 15 and 15'. For example, if the latter shelves are about 14 inches, the shelves 15" may be about 7 /2 inches in width or outward extent.
It will be noted from FIGURE 3 of the drawings that the holder is of a peculiar shape, such that a bolt of material 18 may be tilted outwardly and fully supported on the holder by the thickness of its material at its front portion on and along the back leg portion 200 (see B), and maintained in a supported relation until the bolt is lifted on an inclined plane outwardly off the holder (see C). By making it possible to tilt the bolts 18, as represented by position B, very little overhead space is necessary between the top of one bolt level, tier or row and the bottom of an upper bolt level, tier or row; it has to be only sufficient for a slight arc of movement of the upper end of the bolt being tilted. It will be noted that the cloth bolt 18 is supported in its endwise, vertical upright position (see A) on a shelf by the thickness of the material of its front portion along the front leg portion 20a (see FIGURE 8). Contrary to a conventional type of holder, the holder 20 of my invention does not require lifting the bolt vertically-upwardly for removal or for demonstrating it to a customer. In fact, the material can be displayed to the customer without removing it from the holder by moving it to its second or outer tilted position B. It is thus apparent that a series of bolts may be vertically-positioned above each other with a great savings of space. Also there is nothing to rub against the fabric to soil it, since the bolts 18 can be removed by the clerk by merely placing her hand on the upper end of a supporting mandrel 19 to effect the tilting movement and for slidable removal and insertion of the bolt with respect to the holder 20.
A suitable closely-adjacent side relationship may be re- .tained between upright bolts 18 of each tier, since the holders 20 are slidable along the shelves 15, 15' or 15" and are retained in a set position by the flexibly-clamped-on frictional engagement of their feet with the front and back pair of shelf rail or bar members due to the shape and tensioning of the wire or rod-like upper portions of the holder. The reinfocing back or cross rail members 1110, 13c and 13d of FIGURE 1 also serve to separate side tiers of cloth bolts that are on the same level.
Although, for simplicity of illustration, I have shown shelves 15" only mounted on the front frame 26 of the A or inverted V construction of FIGURE 5, I also contemplate providing slots a along the back frame 26', and detachably-mounting shelves therealong in the same man- In this construction, a lower shelf 15" has a forward-vertical offset relation with an upper shelf 15", such that a loose length of cloth drape from an upper bolt 18 will not tend to cover up the material of a lower cloth bolt.
Although I have illustrated preferred forms of my invention, 'it will be apparent to those skilled in the art that various modifications and additions may be made without departing from its spirit and scope, as indicated by the appended claims.
