Multiple display retainer

Abstract

The present multiple display retainer device is directed to a single polymer extrusion used to retain and display paper, card stock and posters of varying sizes at schools, offices and conference rooms. The device has the capability of retaining one or more articles on the upper side pressure contact area flange, one or more in the central cavity inside surface arid one or more on the lower side pressure contact area flange. Any of the articles held by the retainer may be removed separately without disturbing the other articles.

Description

FIELD OF THE INVENTION[0001]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. Mote 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 he 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 he removed separately without disturbing the other articles. An alternate embodiment of the device will employ barbed sections whereby hanger dips can be employed to support lamer posters or banners of a greater weight.BACKGROUND OF THE INVENTION[0002]In the modern classrooms, wall surfaces tend to be of a smooth non-porous material that can be washed, minimizing the...

AI Technical Summary

Benefits of technology

[0019]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.

[0020]Another advantage is that the multiple display retainer can hold the display materials on the top edge, the central cavity, or the bottom edge.

[0021]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.

Problems solved by technology

This makes it difficult to display articles like homework assignments, artwork or posters.

Often in conference rooms displays and posters need to he put up and removed quickly during a meeting where mounting surfaces are not readily available.

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.

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.

This patent describes another single poster gripping extrusion that will not be capable of retaining more than one item at a time.

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.

Retailers use such devices for hanging display cards or signs from shelves, cases, and ceilings but this NV (not be useful in a classroom to display homework papers.

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.
