Description

RELATED APPLICATIONS

This application is related to provisional patent application Ser. No. 60/930,996 filed May 21, 2007.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The herein disclosed invention finds applicability primarily in libraries, study halls, churches, schools and other such places where one would read books, and papers and would like a comfortable and convenient support to rest them on while the books or papers are being read.

2. Description of Related Art

In the art in which this invention resides, there are to be found many articulated book stands, but none have the special attributes of the herein disclosed invention which will be described hereafter.

BRIEF SUMMARY OF THE INVENTION

The invention is directed to an articulated stand for holding a book at varying heights, while for example being read from a sitting or standing position as is done in many schools, churches and meeting rooms. The articulated stand will hold a book at various heights, and angles, in relation to a table or surface upon which the stand is placed. The multi-level articulated stand is comprised of three rectangular panels (e.g., a bottom panel, middle panel and top panel) that are lined up in a row longitudinally, and connected with two sets of hinges. The hinges enable these three panels to form a Z-shape; that is align as in a letter Z or to collapse downward for storage, into the position of three boards stacked one on top of the other, as will be explained in the drawings. When the stand is in the Z or elevated position, a book placed on the upper surface of the stand can be retained and read in a position elevated from the table. The stand at top level and lower level are held in different positions by use of two U-shaped brackets as will be explained in greater detail hereinafter. A first bracket is between the top and middle panel, and a second bracket is between the middle and bottom panel. The U-shaped bracket can be made of heavy gauge wire. For each U-shaped bracket, the two ends of the bracket, insert into the sides of a panel. A first set of wire ears of the first bracket inserts into the sides of the top panel, and a second set of wire ears of the second bracket inserts in the sides of the middle panel. Bracket feet or tips can pivot into the holes in which they are inserted to keep the articulated stand elevated to different levels. When the stand is collapsed, the wires fold inward, and rest between the wood panels, as will be explained.

Frame Panels

A second method can be used to attach the brackets to the panels. It is for the articulated stand to be made of frames instead of solid rectangle panels as will be explained in reference to the drawings. The ends of the wires are to be inserted from the inside of a rectangular frame instead of the outside.

There are a few types of wires that can be used in the inside. One is “inside wire” and a second is “inside wire flat” as will be described in the drawings.

These two wires have different ways of being inserted into the multi-level stops. As monitored above, in the first method of attaching kickstand (outside wire) the wire kickstand stubs or feet can be inserted in holes on the top surface of the middle and bottom panels. That is that the tip reaches vertically down into the hole. This means that the length of the stub is perpendicular to the hole opening. This same method is used in “inside wire” type. However, in “inside wire flat”, the wire rests in a groove. This means that the stub is perpendicular to the groove and lies in it (see two types of inside wire in the drawings).

DESCRIPTION OF THE INVENTION

With reference to FIGS. 1-6 there are illustrated view of a compact articulated lectern 10 for a book, papers or other such articles. The lectern 10 is multi-level and articulated and has a top panel 12, with a book-stop 14, a center panel 16 and a bottom panel 18. The top panel 12 and center panel 16; and center panel 16 and bottom panel 18 are joined by hinges 32. Shown also in the figures is a rod kickstand 20 with flexible 26, metal sides 28 and feet 30, shown in greater detail in FIG. 5. The sides of the top panel 12 and the sides of the center panel 16 have holes 22 for receiving inboard ears 24 attached at the top of the kickstand 20 (FIG. 5). Note that the wire of the kickstand 20 is flexible enough to allow the inboard ears 24 to be received by the holes 22 in the sides of panels 12 and 16.

The top panel 12, the center panel 16 and the bottom panel 18 are preferably made of wood, but could be made of plastic, metal or any other-like material. The kickstand 20 is preferably made of metal wire, but can also be made of plastic or other like strong and flexible material.

Note particularly with reference to FIGS. 1 and 2 the lectern 10 is in its raised position and can be employed while the reader is standing. By folding in the bottom kickstand into a notch 38 the lectern can be conveniently lowered and used while the reader is sitting.

With reference to FIG. 5 the kickstand has two inboard ears 24, two sides 28 which can be flexed 26 and allow for the inboard ears 24 to be inserted into holes 22 at the edges of panels 12 and 16.

In particular regard to FIGS. 2, 3 and 5, surface holes 34 are shown. These holes are oversized and deep to allow for feet 30 of kickstand 20 to enter the hole 34 at an angle, which would not be possible unless the holes were oversized.

An important feature of this invention is the fact that the bottom frame panel 56 of the lectern in this embodiment is longitudinally shorter than the top frame panel 52 and middle frame panel 54. The advantage to this arrangement is that the reader will be in a position closer to the book-stop and the reading material.

With particular reference to FIG. 6 the lectern is shown in its folded position; allowing for easy storage or transportation. Note also that in FIGS. 1 and 6 there is shown a shallow notch 36 in the top panel and the notch 38 in the bottom panel for neatly receiving the kickstand 20 in the folded position (FIG. 6).

An important feature of this invention is the fact that the bottom panel 18 of the lectern in a preferred embodiment is longitudinally shorter than the top panel 12 and center panel 16. The advantage to this arrangement is that the reader will be in a position closer to the book-stop and the reading material.

FIG. 7 describes a modification of the instant invention showing that the kickstand and keeper-hole arrangement can be used in a two panel compact articulated lectern 40 and in other like applications which require adjustable inclination. The lectern 40 is a two panel lectern having a top panel 42 and a bottom panel 44. The top panel 42 and the bottom panel 18 are joined by hinge. Shown also is a rod kickstand 20. There are holes 34 in the bottom panel 44 of the lectern 40. The holes 34 are oversized and deep to allow for feet of kickstand 20 to enter the holes 34 at an angle, which would not be possible unless the holes were oversized.

With reference to FIGS. 8-10 an alternative embodiment of the compact articulated lectern 50 envisions the use of frame panels. There being a top frame panel 52, a middle frame panel 54 and a bottom frame panel 56. The top frame panel 52 and the middle frame panel 54; and the middle frame panel 54 and the bottom frame panel 56 are joined by hinges. The top frame panel 52, the middle frame panel 54 and the bottom frame panel 56 each have through openings. The frame panels are articulated using U-shaped wire kickstands. One type of wire kickstand 70 (FIG. 11B) has a U-shape with outboard ears 60 at the top of the U-shape to be inserted into a plurality of inboard holes 62 in the inner part of the frame; and the bottom of the U-shape has a nipple 64 which extends out beyond the U-shape to attach itself to a keeper slot 66 on the wood frame. There is also contemplated a U-shape kickstand 70 (FIG. 11A) having outboard ears 60 at the top of the U-shape and extended outboard feet 74 projecting outward and downward from the U-shape of the kickstand. The outboard ears 60 attach to the plurality of inboard holes 62 in the frame and the extended outboard feet 74 insert into surface holes 68. The surface holes 68 are oversized and deep to allow for feet of kickstand 70 to enter the surface holes 68 at an angle, which would not be possible unless the holes were oversized. In FIGS. 8-10 the book stop is identified as 58.

The keeper slots 66 and the surface holes 68, in a preferred embodiment, do not extend across the full width of the frame member. This minimizes the thinning of the frame member except in the area of the keeper slots 66 or the surface holes 68. This has the advantage of increasing the strength of the frame member.

The top frame panel 52, the middle frame panel 54 and the bottom frame panel 56 are preferable made of wood, but could be made of plastic, metal or any other material. The kickstand 70 is preferable made of metal wire, but can also be made of plastic or other like strong and flexible material.

With reference to FIG. 11, there is shown a series of wires 11 A-11E which could be used with the frame-lectern 50 of FIGS. 8-10. With particular reference to FIG. 8 and wire kickstand 70 (FIG. 11E) having inboard ears 76 that fits into an outboard holes 78 and having bottom corner angle 80 that fits into keeper slots 66. Wire kickstands 70 (FIGS. 11A-11D) would in a like fashion fit into keeper slots 66 or inboard holes 62 as would be understood by one skilled in the art.

With reference to FIG. 11 there are shown a series of U-shape kickstands 70 designed to articulate a frame lectern 50. FIGS. 11A-11D have outboard ears 60 to fit into an inboard holes 62 in the frame. FIG. 11E has inboard ears 76 to fit in the outboard holes 78 on the outer side of the frame as shown in FIGS. 8 and 10. With reference to FIGS. 11A-11E the bottom of the U-shaped kickstand is fashioned with projections to be received in keeper slots 66 or surface holes 68 on the frame surface. Note that FIG. 11A has extended outward feet 74 to be received in the surface holes 68. FIGS. 11B-11C have projections or nipples 64 to be received in notches or keeper slots 66. With reference to FIGS. 11D-11E the bottom corners of the U-shaped kickstand 70 are provided with an indent 80 to be received in keeper slots 66 FIG. 8.

With reference to FIGS. 8-11 attention is brought to the fact that the frame panels are all of equal size and therefore with particular reference to FIGS. 11A-11D where outboard ears 60 fit into the inside portion of the frame there are provided outward projections 64, 74 and 80 to fit in keeper slots 66 on the frame below the outward projections. In this regard particular attention is directed to FIG. 8. An advantage of the frames being of uniform size is economy in manufacture.

There may be a notch in the top frame panel 52 and the notch 38 in the bottom frame panel for neatly receiving the kickstands 70 in the folded position.
