Display boards such as dry-erase boards or “whiteboards” are commonly used for the presentation of graphics and written material during presentations. The majority of dry-erase boards consist of a writing surface and a surrounding frame, and are designed to be permanently hung or mounted to a wall. Permanently mounted boards are satisfactory for use in rooms where a constant need exists for the board, such as in classrooms. However, many presentations take place where a permanently installed board may not be available or desired (such as for aesthetic considerations). In such situations, at least the temporary availability of a board is desired.
There are examples of dry-erase boards that are portable. The portable dry-erase boards have easel stand-like legs incorporated into their design. Unfortunately, the portable boards tend to be bulky, complicated to set up, relatively unsteady during use, and provide limited display or writing space. Further, the portable boards are not very versatile, in that they can only be easily used with the incorporated legs and are therefore not readily adaptable to use with different support structures that may be available, such as easel stands (that may be sturdier than the incorporated legs), tabletops (that may be more appropriate in some applications), or available wall mounts. For example, many rooms that are used periodically for presentations or meetings, although not having permanently mounted boards, do have easel stands readily available. Commonly available are easel stands of the type designed to hold large pads of paper (“easel pads”), where individual sheets may be torn off to reveal a new sheet, or alternately flipped over the top of the pad as a “flip chart.”
Easel stands maintain the easel pads on the easel stand in a variety of manners. For example, a tray may protrude from the easel stand to support the easel pad from the bottom, such that the top of the pad simply reclines against the easel stand. Some easel stands have posts extending from an upper portion of the easel stand that are designed to engage pre-punched holes in a top portion of the easel pad. After the pad is positioned on the posts, a retaining member typically engages the ends of the posts to secure the pad. Other easel stands have a clamping member for accepting the top edge of an easel pad. The clamping members include spring-type clamps, manual clamps, and gravity-aided cam mechanisms, for example. Usually, clamping members have a capacity limited to dimensions of a typical easel pad thickness (e.g., approximately ¼ to ⅜ inch thick).
Given the above, a display board having improved performance and versatility would be desirable. In particular, a display board that is easily mounted to a variety of easel stands or other support structures is desirable.
One aspect of the invention described herein provides a display board that may be supported on an easel stand. In one embodiment according to the invention, the display board comprises a panel having a display surface on a front side thereof. A mounting interface is positioned adjacent a top edge of the panel. The mounting interface is configured for releasable engagement with any one of a plurality of unique easel stand securing means, wherein the mounting interface has a thickness less than a thickness of the panel.
In another embodiment according to the invention, the board comprises a panel having a writing surface on a front side thereof, wherein the panel has a thickness greater than a capacity of an easel stand securing means. A mounting interface is positioned adjacent a top edge of the panel. The mounting interface has a thickness less than the thickness of the panel, and is configured for engagement with a clamp member of an easel stand and a support post member of an easel stand.
Another aspect of the invention described herein provides a portable display board. In one embodiment according to the invention, the display board comprises a hinged panel having a first thickness. The panel is selectively positionable in an open position and a closed position, wherein when the panel is in the open position a substantially continuous display surface is formed. A mounting interface is positioned adjacent the top edge of the panel. The mounting interface has a second thickness, wherein the second thickness is less than the first thickness. The mounting interface is configured for engagement with a clamp member of an easel stand and a support post member of an easel stand. A handle is positioned adjacent a lateral edge of the panel for transporting the display board when the panel is in the closed position.

The panel 12 may have any suitable size and aspect ratio (height to width), as is appropriate for its intended use. In one embodiment the panel 12 has a width (from side to side) of approximately 36 inches or greater, and preferably approximately 48 inches or greater. In one embodiment, the panel 12 is approximately 48 inches wide and 36 inches high (from top edge 14 to bottom edge 16). In the illustrated embodiments, the panel has a “landscape” orientation, wherein the width of the panel is greater than the height of the panel. In other embodiments, the panel 12 may have a “portrait” orientations, wherein the height of the panel is greater than the width of the panel.
The display surface 30 may be provided with any of a variety of functional attributes. Exemplary functional attributes of the display surface 30 include, but are not limited to, a writable surface such as a dry-erase board or a chalk board, a tackified adhesive surface, a magnetic surface, or a cork board. The display surface 30 may have more than one functional attribute. In one embodiment, different functional attributes are associated with different portions of the display surface 30. For example, a first portion of the display surface 30 may be a writable surface, while a second portion of the display surface 30 is a tackified adhesive surface. In another embodiment, different functional attributes are associated with the same portion of the display surface 30. For example, a writable surface may also be a magnetic surface.
The panel 12 includes a mounting interface 40 adjacent the top edge of the panel 12. The mounting interface 40 is configured for use with any of a plurality of unique securing or mounting means, such that the versatility of the display board 10 is increased. In one embodiment, the mounting interface 40 includes features enabling the display board 10 to make use of the various clamps, support posts, and cam mechanisms most often found on easel stands that were originally designed for thinner easel pads. In one embodiment, the mounting interface 40 is configured to allow the display board 10 to be mounted on a wall as a conventional wall-mounted board, and then easily removed from the wall for use with any of a variety of easel stands.
As can best be seen in
In one embodiment, the thickness t1 of the mounting interface 40 is substantially constant from side to side and from top to bottom. In one embodiment, the thickness t1 of the mounting interface 40 decreases from the top edge 14 toward the center of the panel 12. The constant thickness, or decreasing thickness from the top edge 14 toward the center of the panel 12 increases the ability of a clamping member to securely engage the mounting interface 40. In one embodiment, at least one of the front surface 22 and the back surface 24 of the mounting interface 40 is adapted to further aide engagement with a clamp member. In one embodiment, at least one of the front surface 22 and the back surface 24 of the mounting interface 40 includes a ribbed surface, a grooved surface, or other textured surface, such that the surface resists slipping when clamped. In another embodiment, at least one of the front surface 22 and the back surface 24 of the mounting interface 40 includes a non-skid material.
In one embodiment, the mounting interface 40 includes elongated through-slots 50 positioned adjacent opposite lateral ends 44, 46 of the mounting interface 40. The through-slots 50 are generally parallel to the top edge 14 of the panel 12, and adapted to receive support members, such as posts or pins, of an easel stand therein. The positions and dimensions of the slots 50 are selected to maximize the variety of easel stand support members that the slots 50 may receive. The through-slots 50 may also receive support posts extending from a wall, such that the display board 10 may be removably supported thereon. In one embodiment, the slots 50 are positioned approximately 0.5 inches or less from the top edge 14. In one embodiment, the inner ends 52 of the slots 50 are spaced at least approximately 12 inches apart. In one embodiment, the outer ends 54 of the slots 50 are spaced no more than approximately 22 inches apart. In one embodiment, the slots 50 are configured to receive a post or pin having a diameter of approximately ¼ to ⅜ inches.
Another embodiment of a display board 100 according to the invention is illustrated in

In one embodiment, each of the first and second panel sections 112a, 112b have a portion of a mounting interface 40 thereon. When the first and second panel sections 112a, 112b are in the open position, the portions of the mounting interface 40 of the first and second panel sections 112a, 112b form a complete mounting interface 40 substantially as described above with reference to
In one embodiment, at least one of the first and second panel sections 112a, 112b has a handle for transporting the display board 100. In one embodiment, at least one of the first and second panel sections 112a, 112b includes an elongated opening 148 extending substantially parallel to the side edges 118, 120 to form a handle for transporting the display board 100 when the first and second sections 112a, 112b are in the closed position. In one embodiment, both the first and second panel sections 112a, 112b include an elongated opening 148 extending substantially parallel to the side edges 118, 120, such that when the first and second sections 112a, 112b are in the closed position, the elongated openings 148 together form a handle for transporting the display board 100.
In one embodiment, the display boards 10, 100 are provided with one or more receptacles for holding items such as pens, markers, chalk, etc., that may be used with the display board. In
Advantageously, the display boards 10, 100 of the present invention have the rigidity and appearance of a conventional wall mounted board, and can take advantage of existing easel stands brings to the boards a significant added utility. The display boards 10, 100 may be mounted on a wall, using hangers extending through the through slots 50 along the top edge of the board. The boards 10, 100 may then be easily removed from the wall, either for esthetic purposes or to transport the board to another location. The boards 10, 100 may further be supported on an easel stand having support pegs or posts extending therefrom, where the posts extend through the elongated through-slots 50. The boards 10, 100 may also be supported by a clamping member, such as a clamp on an easel stand, which engages the inner mounting interface 40. Being able to use an easel stand to position the display board for presentations or group communications (classes, brain storming, etc.) gives the display boards 10, 100 the increased versatility to be used in multiple locations without the steps associated with permanently hanging or mounting the boards to a wall.
