Cl. 211-45 2 Claims ABSTRACT OF THE DISCLOSURE A display board having a pair of projecting posts for receiving and retaining a pad of paper to the board. The posts are secured to the ends of a bracket on the board and contain slots at the extending ends for receiving blades which are pivotably mounted within the slots for both alignment with the axis of the posts during insertion of the paper and for transverse positioning to maintain the pad on the board. The board also includes brackets secured on the back side for maintaining a space behind the board to receive the pages of the pad when folded over backwards.
This invention relates to an improved display board. More specifically, this invention relates to an educational display board for supporting a large pad of paper or other display media for use as a visual aid device before large audiences.
A common visual display device often used before large audiences is the display board. The board is generally mounted on an easel or against a wall and supports a display medium such as a large pad of paper to permit an instructor to sketch and describe various illustrations on the paper. After an illustration has been described on a sheet of paper, the instructor will fold the sheet behind the board to expose a new sheet. Where many illustrations are involved, the instructor is often required to quickly change the pad of paper during the middle of his lecture in order to continue with his sequence of illustrations. In conventional display boards it is not easy to change the pads of paper due to the means employed in securing the pad to the face of the board. The instructor is required to go behind the board and unfasten a pair of wing-nuts in order to release through-bolts which hold the paper to the front of the board. In mounting a new pad of paper to :a conventional board, the instructor must align each of a pair of holes at the top of the pad of paper with their corresponding holes in the board before being able to insert the through-bolt. The wing-nuts and throughbolts which secure the pad of paper to the board often become misplaced or lost while the board is in use.
In the display board according to the invention, a means for securing the paper is provided which is permanently mounted to the board and which permits the instructor to quickly insert a new pad of paper without having to go behind the board or disassemble the securing means. In place of the through-bolts and wing-nuts utilized in conventional boards, the inventive board employs a pair of posts permanently secured to the board. The ends of the posts contain longitudinal slots into which are inserted pivotably mounted extending portions which may be either aligned with the axis of the stud, such as when the pad of paper is inserted into the board, or positioned transverse to the axis of the post to prevent the pad from becoming detached. The posts cotnain no loose parts which may become misplaced and are easily adjusted by the instructor from the front of the board with a minimum of effort. Moreover, upon inserting the new pad of paper to the board, the instructor need only align the holes of the paper to the studs and is not required as in conventional boards to align the studs with the holes of the board before fastening the paper securely thereto.
The inventive board is also provided with a pair of brackets which extend to the rear to provide a space behind the board for receiving the sheets of paper from the pad as they are folded over at the top during the lecture.
It is therefore an object according to the present invention to provide a display device having an improved means for securing and displaying a pad of paper or other display indicia thereupon.
It is another object according to the present invention to provide a display device which permits the user to quickly change the pad of paper on the board with a minimum of effort and inconveniece.
It is a further object according to the present invention to provide a securing device for display boards which is simple in design, easy to manufacture and reliable in operation.
It is still a further object according to the present invention to provide a securing device for display easel boards which may be readily adapted to conventional display boards.
Other objects and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawing which discloses the embodiments of the present invention. It should be understood, however, that the drawing is designed for the purpose of illustration only and not as a definition of the limits of the invention as to which reference should be made to the appended claims.
In the drawing wherein similar reference characters denote similar elements through the several views:
FIG. 1 is a perspective view of the display board according to the invention; and
FIG. 2. is a cross-sectional view along section 22 of FIG. 1.
Referring to the figures, there is shown the display board 16 according ot the invention having a base portion 18 secured to its bottom end. Located near the upper edge of board 16 is a horizontal mounting plate 14 consisting of a strip of metal, or other similar material, and mounted to board 16 by means of flathead screws 17. Secured adjacent to each end of bracket 14 is a post 10 which projects outwardly and perpendicular to the plane of board 16. Posts 10 may be welded to the ends of bracket 14 or secured thereon by any other conventional means such as by screws 25. At the free end of each of posts 10 is a longitudinal slot 12. Pivotably mounted within slot 12 is a blade 13. Pin 11, secured near the free end of stud 10 and passing perpendicularly through slot 12, maintains blade 13 pivotably restrained within slot 12. The length of at least one end of blade 13 is designed to pass freely within slot 12 so that blade 13 may be aligned in a direction along the axis of post 10. The thickness of blade 13 is made slightly less than the cross-sectional thickness of slot 12 to permit blade 13 to pass freely therethrough.
The length of each of posts 10 is made sufficiently long to accommodate at least one conventional pad of paper of normal thickness. Posts 10 have a diameter and spacing sufficient to accommodate commercially available pads of paper which are prepunched with mounting holes. To mount the paper, blades 13 are first aligned along the axis of posts 10 so that the holes in the paper may slide freely over the body portion. Blades 13 are then positioned transverse with respect to the axis of post 10 so as to form a barrier across the holes in the paper and prevent the pad from being removed from board 16. At least one of the ends of blade 13 may be rounded slightly to accommodate its positioning into slot 12. Moreover, each of the ends of blade 13 serves as a counterbalance for the other in restraining a pad of paper from removing itself from post 10. In order to remove the pad of paper it is only neces- 3 sary to align blades 13 with the axis of post 10 and slide the pad over the body of post 10 01f board 16.
The display board according to the invention may be mounted on an easel or secured against the wall of a room. At the top of board 16 and along each side thereof are secured brackets 15 which maintain the board a sufiicient distance away from its easel or wall mounting to permit the pages of the pad to be folded in back of the board during its use as a display device. Brackets 15 may be constructed from wood or metal, and in addition may be provided with holes for mounting the board to a vertical or inclined surface. Base 18 of the display board may be also provided with a plurality of openings 19 to receive bottles of ink or paint. A groove 20 may also be provided within base 18 to support pencils or other writing devices.
The display board according to the invention may be constructed in any size or shape from conventional materials such as wood, plastic or metal. Posts 10 are preferably constructed from barstock metal to support large pads of paper. Blade 13 may be constructed from any conventional material and need not be pivoted at its center.
While only a single embodiment of the present invention has been shown and described, it will be understood that many other changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
