I ABSTRACT on THE DISCLOSURE ,A coinholder comprising two body members, each being a segment of a hollow cylinder, which are joined together at each end by end-pieces. The end-pieces taper towards the centre of the cylinder to allow relative pivotal movement between the body members about a line parallel to the cylinder axis. A tongue and slot combination, the tongue being attached to one of the body members and the slot being formed in the other, holds the two body members in a predetermined position. In use, the body members are moved relatively to each other to an open position and a row of coins is placed in the trough defined by the two segments. The body members are then released, which members return to a closed position in which the coins are held captive in the trough. The body members are held fixed in the closed position by the tongue and slot combination.
This invention relates to coinholders and particularly those of the type into which several coins of the same size are held face-to-face in a row. Generally speaking, the length of the coinholders is an integral multiple of ten widths of the particular coin being counted.
Many forms of such coin-holders have been proposed but the relatively inexpensive forms have not proved satisfactory.
It is an object of the present invention to provide an inexpensive form of coin holder that is robust.
According to the invention, a coin holder comprises at least two body members each having a surface defining a concave segment of a cylinder, the sum of the segment arcs forming not more than a semi-circle; means connecting the body members for relative pivotal movement about a line parallel to the cylinder axis; and means to hold the body members in a selected position relative to each other.
The line of pivotal movement is preferably coincident with the cylinder axis, or close to it.
Further according to the invention, the body members are connected for movement between a first position in which a coin of substantially the same diameter as the cylinder may be inserted in the plane of the cylinder diameter between them, and a second position in which a coin so placed is entrapped by the body members, the locking means being operative in the second position.
Also according to the invention, the body members are of substantially equal length, and include at each end an end-piece that is a portion of an end of the cylinder.
The end-members preferably include the centre of the cylinder diameter, and are connected to each other at the cylinder diameter centre by means such as pivot pins or hinges. In a preferred form, the body members are two in number and are constructed integrally with each other from a flexible material, the pivot means being a thin strip of the material. Polypropylene has been found suitable for this construction.
Also according to the invention, the coinholder includes means to hold the body members in the first position. In this position, the holder is open and coins of the same diameter as the cylinder maybe dropped into it. In the second position, the'holder is closed, the body members extending round a portion of the coincircumferencc that is greater than a semicircle. The end-pieces prevent egress of the coins through the cylinder ends:
In the preferred form of the invention the locking means comprises a tongue and slot arrangement, the tongue being formed on one of the body members and the slot on the other, the tongue preferably being curved in an arc concentric with the cylinder. The tongue may be provided with stops to correspond with the two positions of the body members. Other forms of locking means, such as a spring-biased clip urging the body members towards the second position, are also feasible.
An embodiment of the invention is described below with reference to the accompanying drawings, in which:
FIGURE 1 is a perspective view from above of a coinholder according to the invention;
FIGURE 2 is a perspective view from below of the coinholder of FIGURE 1;
FIGURE 3 is an end view of the coinholder of FIG- URES 1 and 2, illustrating the open position; and
' FIGURE 4 is a view similar to FIGURE 3, illustrating the closed position.
The coinholder shown in FIGURES 1 and 2 is moulded integrally from polypropylene and comprises two body members 10 and 12, each being a segment of a hollow cylinder. Each segment arc is slightly less than a quadrant. At their ends, the body members have end-pieces 14 and 16, being portions of the ends of the cylinder. The endpieces have a common apex 18 near the centre of the cylinder and are thus connected by a thin, flexible strip of polypropylene which acts as a hinge, permitting relative pivotal movement about a line almost coincident with the cylinder axis.
A curved tongue 20 extends from the body member 10 round the convex surface of the body member 12, passing through a slot 28 in a flange 26 along one edge of the body member 12 (see FIGURE 2). The tongue forks at its free end into two branches 22 and 24, the branch 22 being somewhat longer than the branch 24 and having near its tip a stop pad 32. The branch 24 is raised at its free end relatively to the branch 22. A stop pad 34 is also provided near the root of the tongue 20.
The hinge at 18 has admirable flexibility because of the mechanical properties of polypropylene, and production models have withstood more than 1,000,000 flexions without failure.
FIGURES 1 and 2 illustrate the coinholder midway between the open and closed positions. In FIGURE 3, the holder is shown in the open position, and in FIGURE 4 in the closed position. In the closed position, the arc of the cylinder that includes the two segment arcs encompasses more than a semi-circle, so that coins placed in the trough defined by the segments are held captive. In this position, the stop pad 32 abuts the slotted flange 26 on the body member 12 and prevents the gap between the flanges 26 and 30 from being widened. The tip of the branch 24 of the tongue 20 moreover abuts the opposite side of the flange 26, so that relative pivotal movement to narrow the gap between the body members is also prevented. Coins in the holder are thus securely locked in place. To release them, the branch 24 is depressed to enter the slot 28, and the body members 10 and 12 are pivoted towards each other about the hinge 18 until the stop pad 34 engages the flange 26, preventing further pivotal movement. In this position, shown in FIGURE 3, the cylinder are that includes the segment arcs is virtually a semi-circle, permitting coins to be removed from and inserted in the trough formed by the body members. To close the holder, the body members are drawn apart until the stop member 32 prevents further movement. The
flanges 2 6 and-30 provide a convenient baseoil which the ..may..r st w th, the. trqughtmouth .l,1 pwards-. (st-:e FIGURE 3).
Various alternatives to the structure described above might be provided. For instance, the tongue-and slot arrangernent might be replaced by spring means biassing the body members towards the closed position and suitable stop means to define that position.
As an additional refinement, the holder may include one or more transverse partitions so that any inaccuracies due to worncoins maybe offset.
We claim: w
