oooooq "W" Fm. V 72 BULLETIN BOARD ASSEMBLY The present invention relates to improvements in sheet-mounting devices, and more particularly to a novel and improved device for mounting paper sheets and the like on bulletin boards.

The conventional bulletin board comprises a panel of cork, fibre-board, or other easily-penetrable material, upon which paper sheets, cards or the like are hung by means of a tack or pin which pierces the paper sheet and is embedded in the panel of the bulletin board. Because the panel is made of a relatively soft, penetrable material, it is an easy matter for the user to mount a sheet or card thereon and also to remove it when desired. However, over a period of time, as sheets are mounted and removed from the board, the panels are repeatedly pierced by the tacks, causing mutilation of the board and its inability to hold the tacks.

Hard-wood perforated peg boards are in common use today for the purpose of hanging tools, displays, and the like. These perforated boards are adapted to receive pegs and hooks in the perforations for hanging articles thereon, but such boards are not suitable to be used as bulletin boards because their hard surfaces are not readily penetrable by tacks or sharp-pointed pins, and the perforations therein are too large to retain the thin pins or tacks.

It is an object of the present invention to provide a hard-surface, perforated bulletin board and mounting devices constructed to be used with said board for mounting paper sheets or similar objects thereon. Each of the mounting devices has one or more pegs which fit snugly into perforations of the bulletin board for mounting the devices thereon, and a pin so located on the mounting device as to be guided freely through another of the perforations when the peg is inserted.

Another object of the invention is the provision of a bulletin board'assembly of the character described in which the mounting devices may be inserted and removed during continual use without damaging or mutilating the board.

A further object of the invention is the provision of a bulletin board assembly of the character described which is adapted to hang objects securely thereon regardless of the weight of the object.

A further object of the invention is the provision of a bulletin board assembly which is economical in manufacture, simple and convenient to use, effective for mounting papers or other objects, and is light in weight.

Additional objects and advantages of the invention will become apparent during the course of the following specification when taken in connection with the accompanying drawings, in which:

FIG. 1 is a perspective view of a bulletin board made in accordance with the present invention, with a portion of the board broken away for convenience of illustration;

FIG. 1A is a perspective view of a portion of modified type of bulletin board, with a mounting device of the invention attached thereto and holding a sheet of pa- FIG. 2 is a perspective view, on an enlarged scale, of a mounting device made in accordance with the invention for use with the bulletin boards of FIGS. 1 and 1A;

FIG. 3 is a perspective view showing a portion of the bulletin board of FIG. 1 and the manner in which the mounting device is inserted thereon, a portion of the mounting device being broken away;

FIG. 4 is an enlarged section taken along line 4-4 of FIG. 1A;

FIG. 6 is a perspective view of another modified type of mounting device; and

FIG. 7 is a partial plan view of a bulletin board having perforations shaped to receive the mounting device of FIG. 6.

Referring in detail to the drawings, there is shown in FIG. 1 a bulletin board 10 made in accordance with the present invention, and comprising a perforated panel 12 which cooperates with the mounting devices to be presently described. The panel 12 is made of a rigid material such as sheet metal, rigid plastic, composition board or the like,'and may be hung on a wall surface, provided with an easel for standing on a desk, or the like. In the preferred form shown in FIG. 1, the panel 12 is made integral with or is mounted upon a rectangular frame 14 which terminates in a perpendicular peripheral flange 16 having small openings 17 formed therein for mounting the flange 16 flush against a wall surface by means of nails or tacks inserted through said openings 17. The walls of frame 14 are made of such width as to space the front panel 12 from the wall surface by a sufficient distance to enable a mounting device, of the type hereinafter described, to be inserted in the perforations of the front panel.

The front panel 12 is formed with a plurality of spaced circular perforations 18 which cover substantially the entire area of said panel. These perforations are aligned in horizontal rows and vertical columns in selected arrangements, as will be presently described.

FIG. 2 shows a preferred embodiment of a mounting device 20 constructed to be used with a perforated bulletin board of the type shown in FIG. 1 in order to mount a sheet of paper or the like on said bulletin board. The mounting device 20 comprises a flat base 22 having a pair of

cylindrical pegs

24 and 26 projecting perpendicularly from one surface thereof, and a sharp-pointed pin or tack 28 projecting perpendicularly from the same surface.

The base 22 is made of a rigid material such as plas tic, metal, or the like, and may have any desired shape, although in its preferred form it is made of the rounded, generally triangular shape illustrated, for ease of handling and for convenient visual orientation in mounting the device 20 on the perforated board. The base 22 may also be made circular, oval, ring-shaped, or of selected irregular shapes, providing sufficient area is provided to properly locate the

pegs

24, 26 and pin 28 thereon.

The

pegs

24 and 26 are spaced transversely of each other along a line extending proximate to and substantially parallel to the top wall of the triangular base 22. The pin 28 is located well below this line and is located midway between the

spaced pegs

24 and 26, proximate to the lower apex of the base 22. The

pegs

24, 26 and the pin 28 thus form an inverted isosceles triangle.

In the embodiment of the bulletin board 10 shown in FIG. 1, it will be seen that the perforations 18 are arranged in horizontal rows 30 and that the perforations in each of these horizontal rows are evenly spaced from each other by relatively short distances. The perforations 18 in each of the horizontal rows 30 are also aligned with the corresponding perforations of the other horizontal rows to form vertical columns 32. The spacing between adjacent perforations in each vertical column 32 is equal to'the spacing between adjacent perforations in each horizontal row. The vertical and horizontal distances between perforations are such that the

pegs

24 and 26 of mounting device 20 may be inserted simultaneously in two alternate perforations 18 (Le, perforations spaced apart by a single perforation) and the pin 28 will then automatically extend centrally through the perforation of the next adjacent row or column, which perforation is located centrally between said alternate perforations. The mounting device 20 may therefore be mounted on the panel 12 in the upright vertical position shown in FIG. 3, or it may be inverted, or turned 90 to a horizontal position for mounting.

The

pegs

24 and 26 are sized for insertion through the perforations l8 and-may be made of such diameter as to fit snugly within the perforations and make a tight friction fit therewith. As an alternative, the pegs may be made of smaller diameter but mounted on device 20 so as to diverge away from each other and thereby make a frictional fit with the pair of perforations into which they are inserted. Thus, when the mounting device 20 is mounted on the bulletin board 10, the friction fit of the pegs within the perforations prevent the mounting device 20 from working loose and falling off the board, regardless of the weight of the sheet or other item which the mounting device is supporting. To facilitate insertion of the

pegs

24 and 26 within the perforations 18, the pegs may be provided with tapered or rounded ends 34.

In use of the device 20 for mounting an object, for example a sheet of paper 36 on the board 10, the paper sheet 36 is first placed in its desired position against the front surface of panel 12 with its top edge located between adjacent horizontal rows 30 of perforations 18. With the sheet 36 held in this position, the mounting device 20 is brought against the surface of the front panel 12 and the

pegs

24 and 26 inserted into alternate perforations 18a and 18b in the horizontal row immediately above the top edge of sheet 36, as shown in FIG. 3. This automatically positions the pin 28 in registry with the perforation 18c centered between the alternate perforations and in the horizontal row immediately therebeneath. As the

pegs

24 and 26 are pressed into the perforations 18a and 18b the pin 28 pierces the paper sheet 36 and enters the centered perforation18c.

While the

pegs

24 and 26 are made of substantially the same diameter as the perforations 18, the pin 28 is of appreciably smaller diameter and is positioned to pass centrally through the perforation into which it is inserted. Thus the pin 28 does not puncture the board front panel, and, in fact never comes into contact with said panel, so that the board may be subjected to constant use without wear or damage.

The base 22 may be formed with a large central opening 38 which decreases the weight and bulk of the base, and provides a window to aid in visually aligning the pegs with the perforations and visually sighting the paper sheet to be hung.

FIG. 1A shows a modified embodiment of bulletin board 40 which may be used with the same mounting devices 20. The board 40 has a frame 14 and flange 16 identical to those of board previously described. The front panel 42 is identical to the front panel 12, ex-

cept that the perforations 44 therein are arranged in a different pattern. These perforations are aligned in horizontal rows 46, but each perforation in one horizontal row is offset centrally between a pair of perforations in the adjacent rows. Thus, corresponding perforationsof alternate horizontal rows are aligned to form vertical columns 48. It will be seen in FIG. 1A that the

pegs

24 and 26 may be inserted in any pair of adjacent perforations 44 in a horizontal row or vertical column and the pin 28 will automatically be guided through the centrally offset perforation of the adjacent row or column.

FIG. 4 shows'the mounting device 20 in fully inserted position in the board 40 with the base engaging or lying close against the outer surface of front panel 42, and the paper sheet 36 impaled upon the pin 28 and being pressed between the base 22 and the outer panel surface. The inserted pegs 24 and 26 and the pin 2 project a substantial distance beyond the rear surface of front panel 42, but do not contact the wall surface upon which the bulletin board is mounted because of the width of frame 14. The paper sheet 36 is held in mounted position by virtue of being impaled on the pin 28, and is additionally held firmly by being pressed between a large area of the base 22 and the surface of panel 42.

FIG. 5 illustrates another embodiment of mounting device 50, which in this instance has a narrow elongated body 52 from which project a pair of

pegs

54, 56 and a pin 58. The

pegs

54, 56 and the pin 58 are arranged in a straight line along the longitudinal axis of the elongated body 52, and are spaced apart by distances corresponding to the vertical spacing between perforations in the vertical columns of

boards

10 or 40. In use, when the body 52 is held vertically or horizontally and the

pegs

54 and 56 are inserted into two adjacent perforations of any vertical column or horizontal row the pin 58 will automatically enter the next succeeding perforation of the same column or row. The device 50 therefore provides the same advantage as the previously described device 20, namely, insertion of the

pegs

54 and 56 into two selected perforations will automatically guide the pin 58 accurately through the center of a third perforation, even though the latter perforation is covered by the paper sheet and cannot be seen by the user.

FIG. 6 shows a further modified form of mounting device 60 in which a single peg 62 is employed to mount the device on a perforated board and also to guide the pin 64 accurately into one of the board perforations. In this instance, the peg 62 is formed with a non-circular cross-section, for example, the square cross-section shown in FIG. 6. FIG. 7 shows a portion of bulletin board front panel formed with square perforations 72 sized to receive snugly the square peg 62 of device 60. The peg 62 and pin 64 are spaced along the elongated body 66 of device 60 by a distance corresponding to the vertical spacing of perforations 72 in the bulletin board front panel 70.

With the mounting device 60 held vertically or horizontally, the peg 62 is inserted into one of the noncircular perforations 72 of the bulletin board panel 70. Because the non-circular shape of the peg exactly matches that of the perforation, the mounting device body 66 is oriented to a position in which the pin 64 registers with the center of another perforation 72 and the device is mounted to support a sheet of paper or the like in the manner previously described.

While preferred embodiments of the invention have been shown and described herein, it is obvious that numerous omissions, changes and additions may be made in such embodiments without departing from the spirit and scope of the invention.
