Filed Apr. 20, 1964, $91. No. 361,038 7 claims. or. 211-87 This invention, in general, relates to flexible, perforated display or storage panels structurally adapted to serve as display, storage or similar members. More particularly, these panels have embossments, ribs or like raised portions and perforations in the outer face of the panels for receiving support pins and/r hooks or like projections onbase portions of hooks, brackets, rods, shelves and like supporting members. The panels of the invention are flexible at least around transverse axes thereof so that the panels can be coiled into convenient coils for shipping and merchandising and thereafter ultimately uncoiled when applied to a wall surface or the like.

Hardboard or fiberboard with uniformly spaced perforations are widely used as support sheets for hanging or otherwise supporting on hooks, rods, etc., many types of articles either for storage or for display purposes. This perforated hardboard or fiberboard, however, suffers several disadvantages in areas of convenience and ease of marketing and shipping, for example. Perforated hardboard or fiberboard is rigid and, hence, is commonly sold It is, furthermore, very dense material and heavy, comparatively speaking, and awkward to handle in large sheets, all factors which add materially to the sales price due to handling and shipping costs.

Another disadvantage of these rigid, perforated boards is that they must be applied to a wall or other supporting surface with spacer members between the wall or surface and the rear face of the board to allow space for the pins, hooks or like projections of the supporting hardware to extend through the perforations and hook behind the perforated board. Furthermore, because of the aforesaid disadvantages of the hardboard or fiberboard sheets,

a product is not easily saleable through many kinds of retail outlets, e.g., food supermarkets and grocery stores, retail drug stores and the like.

This invention provides new types of perforated support panels which are lightweight and sufiiciently flexible so that the panels can be coiled during the shipping and marketing thereof. Another advantage of the flexible, perforated panels of the invention is that they can be applied directly on a flat Wall or other surface, a curved wall or other surface, or around the corner of two walls and can be attached directly to the wall or surface.

It is, therefore, a primary object of the invention to provide new and advantageous coilable, perforated panels or strips structurally adapted to serve as display, storage or similar panels or strips.

A further object of the invention is to provide lightweight, coilable panels or strips having an outer face which is perforated for receiving pins, hooks and/or like projections on the bases of hooks, rods, brackets or like supporting members adapted to be attached removably to and supported on said flexible panels or strips.

Still another object of the invention is to provide panels 'or strips of the aforesaid character made of a thermoplastic polymer sheet or strip having embossments in the thermoplastic polymer film or sheet, which embossments have perforations in the face thereof adapted to receive the hooks, pins or like supporting members of hardware adapted to be removably attached to the flexible panel or strip.

Still another object of the invention is to provide panels or strips with embossments of the aforesaid character wherein the embossrnents are arranged in rows transverse to the axis of the panels or strips whereby the strips or panels have bending flexibility in the areas thereof between the transverse rows of embossments or strips so that the strips or panels can be coiled.

A still further and more specific object is to provide panels or strips with embossments of the aforesaid character wherein said embossments have vertical slots adapted to coact with appropriately structured metallic or plastic hardware for supporting the hardware on the flexible panels or strips.

Another specific object of the invention is to provide flexible, embossed panels or strips of the aforesaid character embodying in the front face of the embossment a slot adapted to receive the crossleg of a T-bar support on the hardware plus coacting knobs adapted to hold the crossleg of the T-ba-r in position after it is turned degrees in the slot.

Another specific object of the invention is to provide strength-imparting structures around the perforations in the perforated, flexible panels or strips as aforedescribed to improve the weight bearing characteristics of the thermoplastic film adjacent the perforations.

Another specific object of the invent-ion is to provide flexible, embossed thermoplastic film or sheet panels or strips embodying embossments with strength-imparting radial ribs.

Another specific object of the invention .is to provide coilable panels or strips made of a thermoplastic sheet or film, in which film is provided transversely extending ribs functioning as spacer members for spacing the perforated, front face of the panels or strips outwardly from the Wall or other structure to which the panel is secured.

An important object of the invention is to provide flexible, perforated panels or strips which can be coiled for shipment and marketing.

Another object of the invention is to provide panels or strips of the aforesaid character which can be applied directly to a Wall or other surface by adhesive or the like.

Still another important object of the invention is to provide flexible panels or strips of the aforesaid character in which the hardware-supporting sheet is a thermoplastic film or sheet.

The foregoing and numerous other important objects, advantages and inherent functions of the invention will become apparent as the same is more fully understood from the following description, which, taken in connection with the accompanying drawings, discloses preferred embodiments of the invention.

FIGURE 9 represents a perspective view of a fragment of still another embodiment of the flexible, perforated panels of the invention.

Referring to the drawings there is shown in FIGURES 1 and 2 a fragment of a flexible panel or strip made of a flexible, synthetic polymer sheet. The sheet 10 is formed with thin wall embossments 11 provided thereon at longitudinally spaced intervals, i.e., in rows transverse to the longitudinal axis of the sheet 18. The embossments 11 are composed of a top wall 12, a bottom wall (not shown), side walls 13 and a front face 14. All of said Walls forming the embossments are thin walls of substantially the same thickness as the thickness of the sheet 10. The embossments 11 thus are hollow projections projecting from the front face of the sheet It).

The front face 14 of the embossments has a centrally disposed, vertical, elongated slot 15 extending from the upper edge thereof to the lower portion of the front face. The slot 15 is intersected by a cross slot 16 in the top wall 12 of the embossments. These two slots are slots adapted to slidably receive supporting elements removably mounted on the embossments 11. A large number of these embossments are provided on a given flexible panel or sheet so that the ultimate user thereof can select an a propriately spaced supporting structure or element to suit the particular need.

As shown in FIGURE 2, the flexible panels or strips of the invention are adapted to be directly secured on a wall or like surface 17 by an adhesive layer 13 provided over the non-embossed, rear face of the sheet 10. The adhesive layer 13 preferably is a water-soluble adhesive such as polyvinyl alcohol, partially hydrolyzed polyvinyl acetate, or any other suitable adhesive. The support element shown in FIGURE 2 is a hook 20 having a fiat base 21 adapted to lie against the front face 14 of the embossment. The rear portion of the fiat base 21 has provided thereon a T-bar 22. composed of a vertical leg 23 and a cross leg 24. The vertical leg 23 is received in the vertical slot 15 in the front face 14 While the cross leg 24 is received in the cross slot 16. In fully inserted position, the front face of the cross leg 24 lies against the rear face or wall of the front face 14 of the embossment. when the support element 24) is in fully inserted position,

thus is positioned between the rear face of the flat base 21 and the front face of the cross leg 24, whereby the support element 25) is firmly held on the embossment and is capable of supporting substantial weight loads thereon. The lower edge of the vertical leg 23 has a recessed, curved seat 25 adapted to seat against the bottom edge 26 of the vertical slot 15. This seat constitutes the main weight supporting surface for the support element 20.

The front face 14,

The supporting structure on the front face of the flat.

base 21 may be a hook such as the hook 27 shown in FIGURE 2, or it may be a rod, bracket, ring, or any other structure adapted to hold a member or members to be supported on the flexible panel.

In FIGURE 1, another embodiment of a supporting ele ment is illustrated. This supporting element comprises a flat plate or base 28 having on the rear face thereof the T-bar previously described. The front face of the plate 28 has a vertically extending rib 29, on the lower end of which is supported a ring 30. The ring 30 is the articlesupporting element. It is adapted to receive articles such as screwdrivers, tooth brushes, etc.

The embodiment of FIGURE 3 is similar in many respects to the embodiment of FIGURES 1 and 2. The flexible panel or strip 10A is similarly made of a thermoplastic polymer sheet or film; The sheet or film has an adhesive layer coated on the rear face of theunembossed portion including a layer or coating 18a of water-soluble or other suitable adhesive for adhesively securing the strip or panel to a wall or like surface. The embossments 32 in the embodiment of FIGURE 3 are oval shaped embossments comprising an oval, peripheral wall 33 substantially perpendicular to the plane of the sheet 10A. The oval, front face 34 of the embossments 32 have therein a pair of vertically spaced holes or apertures 35. The holes or apertures 35 are adapted to receive the supporting elements, e.g., hooks, pins, studs, etc. of the supporting elements adapted to be removably attached thereto. In the illustrated embodiment, the supporting element comprises a member having an upper hook 36 turned upwardly and a lower pin or stud 37. The hooks and studs may be inserted in the two apertures of a given face 34, or the upper hook may be inserted in the lower aperture of one face 34 while the stud or pin is inserted in the upper aperture of the next lower face 34. The hooks 36 and pins 37 of the support elements are formed on the back face of a rod or shank member 38, on the front face of which is provided the article supporting member, e.g., the hook 4%.

As in the embodiment of FIGURES 1 and 2, the em bossments 32 in the embodiment of FIGURE 3 are arranged in vertically extending rows and the spaces of the sheet 19A between said rows form bending areas whereby the strip or panel 10A may be coiled as aforedescribed.

The embodiment of FIGURE 8 comprises a sheet or film MD of thermoplastic polymer having formed therein rosette embossments 41. The rosette embossments are advantageously employed because the rosette structure provides a plurality of radially extending, strength imparting ribs 42, giving the embossments 41 added structural strength. The embossments 41 have at the center thereof an aperture 43 adapted to receive hooks, pins, studs and like elements of the article supporting member removably held thereon. Like the previous embodiments, the embossments 41 are arranged in transverse rows so that the portions of the sheet 10D between said rows are flexible portions which can bend in order to coil the panel or strip.

The article-supporting embodiments of hardware shown in conjunction with the embodiment of FIGURE 8 are wire hardware elements. One of these hardware elements comprises a hook 44 having a vertically extending shank 45 with a rearwardly offset hook portion 46 at the upper end thereof. This hook portion is adapted to be inserted into one of the holes 43 of an embossment 41 and hooked behind the rear face of the embossment. A stud or pin 47 extending rearwardly from the lower end of the shank 45 is inserted in another. of the apertures 43 of another embossment 41, providing a double support structure for holding the hook 44 on the strip or panel. The spacing between the upper hook element 46 and the pin or stud 47 may be such that they penetrate adjacent apertures of adjacent embossments, as illustrated, or they may be spaced at greater distances so that they penetrate embossments spaced further apart.

Another type of hardware is shown on the embodiment of FIGURE 8. This hardware has a single support element. It comprises a hook 48 having at the upper end of its shank a rearwardly directed and arcuately bent hook or pigtail member 49. The hook or pigtail member is inserted in one of the apertures 43 and is worked into the aperture until the hook or pigtail portion 49 is fully inserted. In this position, the hook 48 is securely mounted in the panel or strip member.

The embodiment of FIGURE 4 comprises a sheet 10B of thermoplastic polymer having formed therein a plurality of rectangular em'bossments similar in general shape to the embossments of FIGURE 1, and where applicable, like numerals have been used to designate like parts.

The front face 14a of the embossment in the embodiment of FIGURE 4 has a short slot 50 therein. The slot 56 is of a length and width slightly wider and slightly longer than the length and width of the cross leg 51 of a T-bar 52 extending rearwardly from the shank 54 of an article-supporting hook 55. The T-bar 52 comprises the vertical leg 53 and the cross leg 51. The lower end of the shank 54 has provided thereon a hook 55.

The article-supporting element is inserted in the slot 56 by turning the element so that the cross leg 51 is aligned with the slot. After the cross leg 51 has been inserted through the slot, the article-supporting element is turned 90 degrees so that the cross leg 51 sits crosswise across the slot 50. The article-supporting element is held in position in the embossment by means of pairs of spaced projections 56 and 57 on the rear face of the front face 14 of the embossment. These projections or knobs 56 and 57 project sufliciently outwardly from the rear surface of the front face 14a so that the cross leg 51 is held therebetween with the shank 54 of the article-supporting element engaging the front face of the face 14 of the embossment. The projection or knobs 56 and 57 are spaced vertically a distance so that the cross leg 51 is firmly held therebetween when the article-supporting element is in mounted position. If desired, the projections or knobs 56 and 57 may be located so that the leg 53 of the T-bar 52 rests against the bottom edge 58 of the slot or the knobs or projections 56 and 57 may be located so that the T-bar 51 is located slightly above the bottom edge 58 of the slot 56, as illustrated in FIG- URE 4.

The embodiment of FIGURES 6 and 7 differs from the previously described embodiments in that the embossments formed in the thermoplastic polymer sheet or film 61 comprise ribs 63 extending transversely across the entire width of the sheet or film 61. These ribs 63 project forwardly from the rear face 62 of the flexible panels or strips a sufficient distance so that a hollow space is formed behind the ribs 63. The depth of the hollow space is at least sufficient to allow the hardware elements of the character shown, for example, in FIGURE 3 or 8 to be inserted and mounted in the holes 64 provided in the front face of the ribs 63 at predetermined spaced intervals, preferably in aligned rows. The flexible panel or strip 66 of the embodiment of FIGURES 6 and 7 thus comprises an undulating or corrugated sheet or strip of thermoplastic polymer with the axes of the undulations or corrugations running transversely relative to the longitudinal axis of the panel or strip. This arrangement provides a panel or strip having sufficient flexibility around the transverse axes thereof so that the strip or panel can be coiled. As in the other embodiments, the rear face 65 of the rear wall 62 may be provided with a suitable adhesive for adhering the panel or strip to a wall or other surface. The adhesive in the embodiment of FIGURES 6 and 7 comprises a plurality of adhesive coatings or layers in strip form applied to the spaced surfaces 65 on the rearward side of the panels or strips 69.

The embodiment of FIGURE 9 is similar in many respects to the embodiment of FIGURE 6 and, where applicable, like numerals have been used to designate like parts. The flexible panel or strip in the embodiment of FIGURE 9 is composed of two elements or layers. The first layer is an undulated or corrugated thermoplastic polymer sheet of the character described with reference to FIGURES 6 and 7. One of the faces of the undulated or corrugated sheet has applied thereacross a flat, semirigid sheet 67 which may be made of a thermoplastic polymer or, more preferably, a fibrous material such as paperboard, jute board, or the like. The flexible panel or strip of FIGURE 9 may be utilized in one of two ways. The face embodying the fiat sheet 67 may be employed as the front face of the flexible panel or strip whereby a fiat, uniform front face is presented to View. In this case, the sheet 67 is provided with a plurality of holes' or apertures 68 opposite the hollow sections formed behind the strip 67 by the undulating or corrugated sec tions of the thermoplastic sheet 66. The apertures 68 are preferably arranged in transversely extending rows as illustrated in FIGURE 9 at spaced intervals for receiving the pins or studs and/or hooks of hardware of the character illustrated, for example, in FIGURES 3 and 8. If desired, the apertures 68 may be substituted by slots of the character 56 shown in FIGURE 4 for use with articlesupporting elements of the character illustrated in that figure. Alternatively, the flat sheet 67 can be used as the rear sheet, in which case the perforation 68 may be omitted. The advantage in using the sheet 67 as the rear sheet is that it has a larger surface area to which the [adhesive for sticking the panel or strip to a wall or like surface may be applied. In such case, the front faces of the ribs 61 may have provided therein apertures 69 similar in nature to the apertures 64 described with relation to the embodiment of FIGURES 6 and 7.

The embodiment of FIGURE 5 has a plurality of embossrnents arranged on the synthetic, thermoplastic polymer sheet 10C in the fashion similar to the arrangements of the embossments in the previously described embodiment. The embossments in FIGURE 5 are frusto-conical embossments having a plurality of longitudinally extending ribs 72 on the frusto-conical wall thereof. The ribs 72 add structural strength to the frusto-conical walls.

A hole 73 is provided in the center of the front face 74 of the embossment 71. The hole 73 is formed with an annular, rearwardly projecting rib 75 thereabout, which rib imparts additional rigidity to the face 74 in the area of the hole 73. The hole 73 is defined by a rearwardlydirected, circular lip 76 which provides additional surface bearing area at the hole 73. The rearwardly directed lip 76 is beneficial in improving the support characteristics of the hole 73 relative to the hooks, pins, studs, projections or like members inserted therein, for supporting the article-supporting member on the flexible panel or strip. The annular lip 76 improves the tear resistance, creep resistance, and distortion resistance of the thermoplastic sheet in the area of the hole 73.

The rear face of the sheet 10C has applied thereacross in the flat, rear portions thereof a layer of adhesive 77 which bonds a fibrous sheet 73 to the rear face of the sheet 16C. The fibrous sheet 7 3 may be a sheet of paperboard, jute board or other inexpensive fibrous material. The fibrous layer or sheet 73 in turn is bonded by an adhesive film or layer 79 to a wall or other surface 80 to support the flexible panel or sheet on the wall or other surface.

The fibrous sheet 78 provides means for delaminating the sheet 16C from the wall surface when the latter is to be stripped from the wall. The fibers tear when the sheet is pulled off the wall, leaving a fibrous remnant which can be removed along with the adhesive by washing with water or an organic solvent for the'adhesive.

It will be appreciated that the description of the foregoing preferred embodiments of the invention are merely exemplary of a multitude of various arrangements which can be employed in producing a flexible, perforated panel or strip in accordance with the generic concepts of the invention. The various types of article-supporting members illustrated in the foregoing embodiments, for example, can be mounted on embodiments of the perforated, flexible panels or strips with which they are shown in combination in the foregoing embodiments, i.e., a given article-supporting member can be interchanged with appropriate structural changes where necessary to support it on any one of the various embodiments of the flexible panels or strips illustrated.
