Definitions

  • the multiple display retainer relates to devices in many sizes used to retain and display paper, card stock and poster types of materials of varying sizes at schools, offices and conference rooms. More specifically this device deals with the unique capability of retaining one or more articles on the upper side, one or more in the central cavity and one or more on the lower side. Made from a thin flexible polymer material that can easily be cut to length and attached to a wall surface by a variety of attachment means. A second unique feature is that any of the articles held by the retainer may be removed separately without disturbing the other articles.
  • An alternate embodiment of the device will employ barbed sections whereby hanger clips can be employed to support larger posters or banners of a greater weight.
  • wall surfaces tend to be of a smooth non-porous material that can be washed, minimizing the collection of bacteria. Things like, corkboard and tack board are being avoided due to the difficulty in keeping the walls clean and sanitary. This makes it difficult to display articles like homework assignments, artwork or posters. In the elementary grades, children take a great deal of pride in seeing their works displayed on the walls where this has been the common practice for many years. Often in conference rooms displays and posters need to be put up and removed quickly during a meeting where mounting surfaces are not readily available. Smaller sizes of the multiple display retainers will work well in offices and homes for holding notes and reminders. Problems arise where school systems do not want the smooth non-porous surfaces of the walls damaged by the insertion of nails and screws. When masking tape and mending tapes are used to hold the display materials on the walls it is difficult to remove and the walls soon become unsightly.

Description

MULTIPLE DISPLAY RETAINER
FIELD OF THE INVENTION
The multiple display retainer relates to devices in many sizes used to retain and display paper, card stock and poster types of materials of varying sizes at schools, offices and conference rooms. More specifically this device deals with the unique capability of retaining one or more articles on the upper side, one or more in the central cavity and one or more on the lower side. Made from a thin flexible polymer material that can easily be cut to length and attached to a wall surface by a variety of attachment means. A second unique feature is that any of the articles held by the retainer may be removed separately without disturbing the other articles. An alternate embodiment of the device will employ barbed sections whereby hanger clips can be employed to support larger posters or banners of a greater weight.
BACKGROUND OF THE INVENTION
In the modern classrooms, wall surfaces tend to be of a smooth non-porous material that can be washed, minimizing the collection of bacteria. Things like, corkboard and tack board are being avoided due to the difficulty in keeping the walls clean and sanitary. This makes it difficult to display articles like homework assignments, artwork or posters. In the elementary grades, children take a great deal of pride in seeing their works displayed on the walls where this has been the common practice for many years. Often in conference rooms displays and posters need to be put up and removed quickly during a meeting where mounting surfaces are not readily available. Smaller sizes of the multiple display retainers will work well in offices and homes for holding notes and reminders. Problems arise where school systems do not want the smooth non-porous surfaces of the walls damaged by the insertion of nails and screws. When masking tape and mending tapes are used to hold the display materials on the walls it is difficult to remove and the walls soon become unsightly.
Numerous innovations for holding display materials have been provided in the prior art that is described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present application as hereinafter contrasted. The following is a summary of those prior art patents most relevant to the multiple display retainers, as well a description outlining the difference between the features of the present application and those of the prior art.
Patent No.6,510,635 of Susan C. Rudolph describes a frame system for displaying panels such as signs, artwork, photographs, text etc., on a surface such as a wall. Two long tracks have fasteners for fastening them to a surface. Two corresponding cover bars are shaped to slide longitudinally over the tracks while being retained on the tracks. The cover bars have lengthwise grooves for supporting edges of one or more panels between opposite cover bars while allowing the panels to slide along the grooves. Caps are fastened over the ends of the cover bars with removable, tamper resistant, fasteners to prevent the cover bars from being slid out of the tracks until the caps are removed. The system may be mounted on a surface with the tracks horizontal, vertical or any angle in between. While the tracks will ordinarily be mounted parallel to each other, they may be mounted at angles to each other to accommodate panels of shapes other than rectangular.
This patent describes a frame system for displaying panels such as signs, artwork, photographs, text etc. on walls where a larger structure is used, and a permanent attachment means is required. It has not been designed for the easy insertion and removal of a variety of sizes of display materials from individual sheets of paper to posters and banners at the same time.
Patent No. 6,546,657 of Richard John Gray describes a document holder comprising a rigid planar board having one side covered by transparent flexible cover, the board and cover at one end being held in a retaining clip, said clip comprising a substantially planar tongue with a channel extending along one edge thereof with an opening facing away from the tongue.
This patent describes a single document display holder that has not been intended for the use in a classroom to display multiple display materials.
Patent No. 6,467,742 of David E. Pitcher describes a poster gripping extrusion device for the close-in maintenance and rigid support of a flexible sheet of display material. The device includes an elongated planar base having a first or distal edge and a proximal or second edge defining a width of said base. A leg extends parallel to the base, the leg having a distal edge and a proximal edge, and only a single web or bridging portion extending between the second edge and the proximal edge of the leg to provide compactness to the device. A pivotable clamp extends from the distal edge of the leg, the clamp providing a first and a second line of contact between the clamp and the base to securely hold a sheet of material therebetween. The clamp has a distalmost edge which extends beyond the distalmost edge of the base portion of the device, to permit ease of manipulation of the device in "close-in" locations.
This patent describes another single poster gripping extrusion that will not be capable of retaining more than one item at a time. It has been designed to be utilized in commercial and retail display arrangements.
Patent No. 4,629,075 of James E. Hutton describes a mounting strip for clamping flexible sheet material or other objects that includes an elongated U-shaped, rigid plastic channel having a forward leg forming a bearing surface and a rearward leg forming a mounting surface. An elongated flexible gripper tongue is formed along the mounting surface of the channel and includes a clamping surface adapted to engage the bearing surface of the forward leg of the channel for receiving and clamping an article such as sheet material therebetween. The rigid plastic channel and flexible plastic gripper tongue are preferably co-extruded in a single operation to form a one-piece mounting strip having cooperating clamping elements with different durometer harnesses.
This patent describes a mounting strip for clamping flexible sheet material but is not capable of the unique features of holding display materials in three separate locations. This device would also have to be attached to the wall surface by screws or nails which would damage the wall surface.
Patent No. 5,863,019 of Sidney Rose et al. describes an invention comprised of an elongated extruded poster clamp support assembly for the stiff and reliable hanging of a poster or sign therefrom, comprising an elongated planar base having an upper edge and a lower edge, a channel arranged on the upper edge of the planar base, to permit the clamp to be supported, and a pair of elongated legs attached to the channel, the legs arranged to be rotated into a poster holding orientation by movement about a hinge extending from the channel. The legs thereby define two spaced apart pressure strips biased against the base, for the pinching of a poster therebetween. The invention includes an elongated groove arranged as part of the channel, for the receipt of a stiffener rod to help keep flat any poster supported in the clamp.
This patent describes an elongated extruded poster clamp support assembly for the stiff and reliable hanging of a poster or sign. Retailers use such devices for hanging display cards or signs from shelves, cases, and ceilings but this would not be useful in a classroom to display homework papers.
Patent No.4,089,116 of Wells Stone Beringer describes a paper holder that has an upwardly opening slot into which ribs project from each side of the slot. The ribs along the two sides are staggered and alternated with respect to each other so that a single piece of paper inserted into the slot will assume a corrugated configuration and will accordingly remain upright in a free standing position. The base of the holder has a straight edge along which a measuring scale exists so that the holder may also be used for measuring and marking.
This patent describes still another paper holder that will only hold one sheet of paper at a time and requires a permanent mounting to the wall surface.
A primary consideration in the production of clamping or retaining devices of the types described above is to limit manufacturing and fabrication costs without sacrificing their ability to firmly and releasably grip flexible sheet material. One problem with such prior art devices is that the housing and clamping elements are formed in separate manufacturing operations, and then later assembled to form the completed clamping devices. Separate fabrication operations increase manufacturing costs and capital expenditures for the equipment. The cost of the device is further increased by the separate assembly operation required to connect the clamping element and housing.
Another problem with many prior art clamping devices for flexible sheet material is that while the sheet may be inserted directly between the housing and clamping element, it can be removed only by sliding the sheet endwise to one of the ends of the housing and clamping element. This is particularly disadvantageous where the clamping device is fabricated in an elongated strip because the flexible sheet materiel must be moved a large distance to reach the end of the housing and clamping element for removal.
In this respect, before explaining at least one embodiment of the multiple display retainer in detail it is to be understood that this is not limited in its application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings. The multiple display retainer is capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for designing of other structures, methods and systems for carrying out the several purposes of the present design. It is important, therefore, that the claims be regarded as including such equivalent construction insofar as they do not depart from the spirit and scope of the present application.
SUMMARY OF THE INVENTION
The principal advantage of the multiple display retainer is that it can easily be attached to a wall surface for displaying materials, and the resulting displays are quickly and neatly set and changed once the apparatus is installed.
Another advantage is that the multiple display retainer can hold the display materials on the top edge, the central cavity, or the bottom edge.
Yet another advantage is that the multiple display retainer can hold a variety of sizes of materials at the same time, and the apparatus allows the user to display multiple items using a single component.
Another advantage is the ability to add or remove any piece of the display material without disturbing the others being held in adjacent positions.
A further advantage is that the multiple display retainer can be cut to any length required with a pair of scissors, and it is able to be altered in length at the time of use by cutting with common scissors, thus making its versatility invaluable in being scalable to any display space size, making available display space maximized.
Yet another advantage is that the multiple display retainer or the alternate embodiment of the multiple display retainer can hold larger or heavier materials by the means of hanger clips.
Another advantage with the multiple display retainer is that it can be attached to wall surfaces by a variety of different means, and the device can be used permanently or can be removed and used again without waste, thus being an environmentally friendly answer to what is typically wasteful.
Yet a further advantage with the multiple display retainer is that it can be split down the middle if only one half is required, and the cost is considerably less compared to typical display items that function in a far less versatile manner. And still a further advantage is that the multiple display retainer can be adhered and removed from the wall without damaging the surface, likewise, the displayed materials are not damaged when displayed, and thus allowing them to be reused unlike conventional display systems.
And yet another advantage of multiple display retainer is to add a means of holding and displaying materials in classrooms where corkboard and tack board are no longer in use and the wall surfaces are a smooth, cleanable, and of non-porous materials.
