Filed Aug. 28, 1961 CLARENCE M BAINS INVENTOR 8W ATTORNEY United States Patent 3,064,805 COIN DISPLAY Clarence M. Bains, Glendale, Calif. (4811 Meadowbrook Drive, Fort Worth 3, Tex.)

Filed Aug. 28, 1961, Ser. No. 134,517 3 Claims. (Cl. 206-.83)

This invention relates to coin display holders and is directed more particularly to that type of holder which can be combined in book form by means of binder screws or which can be inserted into a loose leaf cover of conventional design.

In displaying coins it is customary to have both sides of the coin visible through transparent protective covers which allow minute examination, yet which protect the coin against handling and misplacement or loss. This invention is directed to a new and novel way of mounting a number of coins in preformed apertures over which a transparent slide can be afiixed on each side, the entire display forming a neat, attractive and durable sheet with flush surfaces which can be combined with other similar sheets in the manner of pages in a notebook. All the parts of the display holder can be molded from polyethylene plastic or other suitable material.

In the accompanying illustration, which is a part of the description:

FIGURE 1 is a general perspective view of one of the display holders.

FIGURE 2 is a partial horizontal cross section of the holder.

FIGURE 3 is an enlarged detail of a vertical cross section.

FIGURE 4 is a perspective detail of the binder strip comprising a part of each holder.

FIGURE 5 is a perspective detail of one corner of the holder body which locks into the binder strip.

FIGURE 6 is a perspective detail of an alternate form of the holder body.

FIGURE 7 is a partially cut away detail of a number of holders bound in notebook form.

In the preferred form of the invention the assembled holder 10 consists of a main body 11 molded, or otherwise formed, from either transparent or opaque plastic and having in each surface a number of shallow horizontal channels 12 so disposed that the opposite channels on the front and back of the body are aligned to form a web 13 slightly thicker than the coins to be displayed. Each such web contains variou sizes of apertures 14 into which coins or similar objects can be inserted.

The edges of the channel 12 are undercut to receive the similarly shaped edges of a set of transparent slides 16 which match the sizes of the various channels 12 and are also molded or formed from a suitable plastic. These transparent slides 16 are of a thickness equal to the depth of the channels 12 so that when they are in place the body assembly presents a smooth surface without ridges or grooves. Each slide 16 has on its inner surface near the inner end a detent 16a which snaps into a corresponding dimple 16b in the bottom of the channel 12 to hold the slide 16 in place while the body 11 is detached from the hinge trip 17, referred to hereinafter.

To complete the holder assembly 10, a hinge strip 17 is slidably attached to the body 11 by means of a dovetail joint 18 running along one edge 19 of the body 11 which engages a matching channel 20 in the adjacent edge 21 of the hinge strip 17. The base of this dovetail 18 consists of a shoulder 18a which the edge 21 of the hinge strip 17 fits against. One end 22 of each slide 16 is finished square to bear against this shoulder 18a when the slide is inserted all the way into the channel 12 so that when the slides 16 are in place and the hinge strip 17 is slid upwardly from the bottom of the body 11 along the dovetail 18, the holder 10 i smooth and continuous on all sides except for the raised ridges 11a on the body 11 and 17a on the hinge strip 17 which protect the surface of the slides 16 from contact with each other and consequent abrasion. If preferred, the ridges 16 may extend across the top and bottom only. Each hinge strip 17 has a thinned portion 17b running its length which is flexible enough to allow the bound holders 10 to be opened like a book as shown in FIGURE 7.

A stop 23 is molded or formed on the top corner of the body 11 which is received by a cutout 24 on the hinge strip 17. This keeps the body 11 located in relation to the hinge strip 17 and prevents the pages composed f the body 11 and the slides 16 from accidentally falling out of the hinge strip. The hinge strip 17 is supplied with holes 25 into which can be inserted binder screws 26 to make up the holders 10 into hooks, or the holders can be bound similarly into a standard loose leaf cover 27 which can be tilted or decorated. FIGURE 5 shows a portion of one of the slides 16 as it is withdrawn from the channel 12 past the dovetail 13 after the hinge strip 17 has been removed.

The advantages of this type of coin display holder are readily apparent. It is a simple matter to remove one body from the hinge strip and then remove one or more slides for access to the coins, and until the body is removed from the hinge strip the slides are locked in place. While access to the coins or coin apertures is relatively simple, it cannot be accomplished without an easily detected manipulation and removal of the Whole assembly, thus discouraging pilfering. The insertion of a screw 28 into a threaded hole in the dovetail joint makes it even more difiicult for unauthorized persons to remove a coin unnoticed. The flush surfaces of the assembled holder have already been described, and these add greatly to the appearance of the display and facilitate keeping it clean.

In a modified form of the invention shown in FIGURE 6 the channels 12 are continued through the dovetail joint 18 making it possible to use a thinner web 13 and hence a thinner body 11, making the entire display more compact.

The invention is not limited to the construction herein shown and described, but may be made in many ways within the scope of the appended claims.

What is claimed is:

l. A coin display holder comprising a flat rectangular body, a hinge strip slidably dovetailed to one edge of said body, said hinge strip having a lengthwise thinned portion for hinge line flexibility, opposed parallel channels in the respective surfaces of said body and perpendicular to said hinge strip, said channels being open at the end adjacent said hinge strip and closed at the opposite end, said channels forming a web therebetween slightly thicker than the coins to be displayed, perforations in said webs to receive said coins, transparent slides fit ting into said channels and covering said perforations, one end of each said slide abutting the edge of said hinge strip, and holes in said hinge strip positioned for receiving retainers.

2. A coin display holder of fiat rectangular shape comprising a hinge strip having holes for retainers, a body containing aligned rows of perforations to receive the coins to be displayed, a sliding dovetail joint connecting said hinge strip and said body, shallow channels with undercut edges in the front and back surfaces of said body, said channels being paired front and back to form a web along said rows of perforations, said channels running perpendicular to said dovetail joint and being open L) at the end adjoining said joint and closed at the opposite end, transparent slides fitting lengthwise into said channels and retained therein by said undercut edges of said channels, each said slide being of a length to butt against the edge of saidbinderstrip.

3. A coin display holder as described in claim 2 having at thevtop end of. said sliding dovetail joint on said body a laterally projecting stopand a matching cutout at the top end of said sliding dovetail joint on said binder body by sliding in one directiQn, nly.
