Abstract
A flat foldable carrying case with a closed interior space is unfoldable to yield a lectern. The lectern/carrying case is formed from a box as well as left, right, bottom, and top flaps. The box has four sides which are connected to a back side, each at a right angle thereto. Each side of the box is rotatably adjoined to a respective side flap. The bottom flap is foldable after the sometimes identically sized left and right flaps fold into the box. Then the top flap is foldable. In some cases, the bottom flap is only foldable towards the box after the left and right flags are folded due to a wider bottom flap compared to the side flaps. In a folded condition with enclosed interior space, the top flap is parallel to the back side of the box.

DETAILED DESCRIPTION
(19) A flat foldable carrying case with a closed interior space is unfoldable to yield a lectern. The lectern/carrying case is formed from a box as well as left, right, bottom, and top flaps. The box has four sides which are connected to a back side, each at a right angle thereto. Each side of the box is rotatably adjoined to a respective side flap. The bottom flap is foldable after the sometimes identically sized left and right flaps fold into the box. Then the top flap is foldable. In some cases, the bottom flap is only foldable towards the box after the left and right flags are folded due to a wider bottom flap compared to the side flaps. In a folded condition with enclosed interior space, the top flap is parallel to the back side of the box.
(20) Embodiments of the disclosed technology will become more clear in view of the following description of the figures.
(21) FIG. 1 is a top and front side perspective view of the foldable lectern in a carrying case configuration in an embodiment of the disclosed technology. FIG. 2 is a bottom and back side perspective view of the foldable lectern in a carrying case configuration in an embodiment of the disclosed technology. Discussing FIG. 1 and FIG. 2 simultaneously, a handle 66 is on a top side 28 of a box 10. The box has sides 24 and 26 (and further sides which are shown/discussed with reference to figures below). In addition, a rotatably attached planar outcropping an/or extension from the top side 28 of the box is flap 18. The top flange 30, a rotatably attached planar outcropping to flap 18 is also shown. The lectern also comprises placement holders 62 and 64, which are laterally placed, parallel strips of material, raised from the surface of 18. The placement holders prevent a book or other object placed on the top flange 30 from sliding downwards past the a placement holder, in a lectern configuration shown in later figures.
(22) In a carrying case configuration, handle 66 is usable to hold and move the case/lectern while the carrying case remains closed. Further, the carrying case has opposite sides which remain parallel to one another, rendering an easy to handle rectangular prism form. Aided by internal magnets, the rotatably attached top flap 18 and top flange 30 lie flat against the rest of the carrying case, aiding in the formation of a substantially or exactly (within a tolerance level acceptable in the art) rectangular prism shape.
(23) FIG. 3 is a top and front side perspective view of the foldable lectern in a carrying case configuration, as top flap 18 and top flange 30 are in the process of being unfolded in an embodiment of the disclosed technology. FIG. 4 is a bottom and front side perspective view of the foldable lectern in a carrying case configuration, as top flap 18 and top flange 30 are in the process of being unfolded in an embodiment of the disclosed technology. Additionally depicted in FIG. 3 and FIG. 4 are box sides 24, 26, and 28, handle 66, and placement holders 64 and 66. FIG. 3 and FIG. 4 illustrate a beginning stage of a process of the lecterns unfolding, which enables the lectern to transition from a carrying case configuration to a lectern configuration. While the carrying case configuration allows storage and transport therein, the lectern configuration allows support for an object on the sloped top flap 18/top flange 30 as well as storage within the lectern.
(24) FIG. 5 is a top and front side perspective view of the foldable lectern in a transitional configuration, while FIG. 6 is a bottom and front side perspective view of the foldable lectern in a transitional configuration. The transitional configuration is a state where the elements of the device 10 are partially in, or between, a lectern and carrying case configuration. In both FIG. 5 and FIG. 6, the top flap 18 and top flange 30 are shown fully unfolded into their respective positions, which will allow for side flaps 12 and 14 to be unfolded into their proper positions for lectern configuration, without top flap and top flange 18 and 30 respectively interfering with this process. Bottom flap 16 is partially unfolded. Box flaps 12, 14, 16, and 18 comprise a system in which one of the side flaps 12 or 14 must be folded over the other respective side flap and only then can bottom flap 16 be folded inwards. This is because the flaps vary in length, as well as their respective securement placements with respect to the box. Following these steps, the top flap and flange 18 and 30 respectively can be folded downwards over the other stowed flaps. This storage system thus allows for a method by which all four flaps can be folded inwards to transition the lectern to carrying case configuration, or folded outwards to yield the process of transitioning the lectern into functional lectern configuration. Additionally depicted are box sides 20, 24, 26, and 28, placement holders 62 and 64, and handle 66.
(25) FIG. 7 is a top and front side perspective view of the foldable lectern in a transitional configuration, while FIG. 8 is a bottom and front side perspective view of the foldable lectern in a transitional configuration. In both FIG. 7 and FIG. 8, top flap 18 and top flange 30 are shown fully unfolded into their respective positions, which will allow for side flaps 12 and 14 to be unfolded into their proper positions for lectern configuration, without top flap and top flange 18 and 30 respectively interfering with this process. Bottom flap 16 is completely unfolded for the eventual completion of the transition of the lectern into lectern configuration. Additionally depicted are box sides 20, 24, 26, and 28, placement holders 62 and 64, and handle 66.
(26) FIG. 9 is a top and front side perspective view of the foldable lectern in a transitional configuration, while FIG. 10 is a bottom and front side perspective view of the foldable lectern in a transitional configuration. In both FIG. 9 and FIG. 10, top flap 18 is shown fully unfolded, which will allow for side flaps 12 and 14 to be unfolded into their proper positions for lectern configuration, without top flap 18 interfering with this process. Flap 14 is depicted as partially open, whereas flap 12 is still entirely closed. Top flange 30 is depicted sloping downwards at an angle demonstrative of the capabilities of the rotationally attached components. In further figures, top flange 30 will be depicted in other configurations to further illustrate this capability.
(27) Additionally depicted are box sides 20, 24, 26, and 28, placement holders 62 and 64, and handle 66.
(28) FIG. 11 is a top and front side perspective view of the foldable lectern in lectern configuration, while FIG. 12 is a bottom and front side perspective view of the foldable lectern in lectern configuration. In both FIG. 11 and FIG. 12, flaps 12, 14, and 16 are shown to be open to the full extent intended for the transition to and usage of the lectern configuration. Flap 18, which is rotationally attached to box side 28 and top flange 30, is shown sloping downwards. This is to enable the user of the lectern to utilize the surface of flap 18 for the placement of reading material and secure it between placement holders 62 and 64. Top flange 30 is positioned such that its height (the dimension of the flange bisected by an imaginary transversal spanning from flap 12 to flap 14) is perpendicular to the ground. Components 32, 34, 36, and 38, which are the lips of their respective flaps or flanges, comprise the boundaries of portal 4 which leads to interior space 8. The portal is open only on a side of the lectern in embodiments of the disclosed technology. This portal has a substantially rectangular shape. The partition of interior space 8 from the environs outside the lectern by means of the placement of the aforementioned and described further below. The lectern components give interior space 8 functionality as an area of storage for the user of the lectern. Box sides 20, 22, 24, 26, and 28 are depicted, as well as placement holders 62 and 64, and handle 66.
(29) FIG. 13 is a top and front side perspective view of the foldable lectern in a transitory unfolded, while FIG. 14 is a bottom, front, and side perspective view of the foldable lectern in a transitory unfolded configuration in an embodiment of the disclosed technology. In both FIG. 13 and FIG. 14, box sides 20, 22, 24, 26, and 28 are shown. Flaps 12, 14, 16, and 18 are rotationally secured to their respective box sides. Depicted are the rotational capabilities of these flaps, as in FIG. 13 and FIG. 14 the flaps are rotated outwards even more than that which is necessary for both the carrying case and lectern configurations. Also depicted are top flange 30, placement holders 62 and 64, and handle 66.
(30) FIG. 15 is a top, back, and side perspective view of the foldable lectern in a lectern configuration, while FIG. 16 is a bottom, back, and side perspective view of the foldable lectern in a lectern configuration in an embodiment of the disclosed technology. Depicted is the rigid construction of the unfolded flaps 12, 14, 16, and 18 and the box sides 20, 22, 26, and 28. Placement holders 62 and 64 are present, as well as handle 66.
(31) FIG. 17 is a version of the foldable lectern with an elevated top from a front, side, and top perspective view, while FIG. 18 is a version of the foldable lectern with an elevated top from a front, side, and bottom perspective view. Both FIG. 17 and FIG. 18 depict flange 30 resting upon flaps 12 and 14, the point of contact between the flaps and the flange being the lip of the flange, which is component number 32. The angle formed between the back box wall 20 and the top flange is obtuse. This change is designed to allow the user of the lectern to be able to angle their reading material, which is stored between placement holders 62 and 64, in multiple orientations. Magnets 40, 42, 44, 46, 48, 50, 52, 54, 56, 58, and 60 which are embedded within flaps and flange 12, 14, 16, 18, and 30, are located adjacent to the lips of their respective flaps and flange respectively. Due to the dual placement of pairs of magnets within each respective side flap 12 and 14, even more possible orientations/elevations of the top flap 18 and flange 30 are possible. Each magnet is placed correspondingly to another magnet, thus enhancing the symmetry of this embodiment of the technology. Also depicted are handle 66 and walls 22, 24, 26, and N28.
