Truncated pyramidal golf ball positioning device
A positioning device that includes a hopper and tray configured to define an internal cavity when in a closed position that accommodates being filled with golf stacked to form a pyramidal shape. The hopper and tray each have a surface that stably self-supports the positioning device without toppling on a flat, horizontal surface. The hopper and tray may have retainers that them to each other and have a hinge that hinges a common side. The hinge may be configured to swing apart the tray and hopper when their retainers are separated from each other. When in the closed position, the positioning device may be stably stacked between two other positioning devices that are identical to it in configuration. An indentation may project into the internal cavity or a stacking insert may be placed within the internal cavity to take up space otherwise filled by one or more golf balls.
1. Field of the Invention
The present invention relates to a positioning device having a hopper and a tray that are formed to stack golf balls arranged within into a truncated pyramid stack.
2. Discussion of Related Art
Positioning devices capable of stacking golf balls to form a pyramidal stack of golf balls are known from U.S. Pat. No. 5,551,832 and U.S. Pat. No. 5,595,312. The devices include a pyramidal shaped hopper that is placed in a tray. A base layer of the pyramidal stack of golf balls rests on the tray.
If one were to invert the hopper and rest the apex on a flat, horizontal surface, the hopper would topple. This is because the dimension of top of the apex is too small to stably self-support the hopper. Similarly, if the hopper is upright on the tray and a further tray of another positioning device is placed on top of the apex of the pyramid shape of the upright hopper, this further tray would topple for the same reason. In other words, filled pyramidal positioning devices can not be stably self-stacked one atop the other because they topple due to the relatively small dimension at the top of the apex of the pyramid shape.
Retailers desirous of stocking such filled pyramidal positioning devices, therefore, are unable to readily stack one atop the other to conserve floor or shelf space. Instead, they may stock filled pyramidal positioning devices without stacking them and they may stock empty pyramidal positioning devices that can be stacked.
It would be desirable to configure the pyramidal positioning devices to enable them to be stacked one atop the other when they are filled with golf balls.
SUMMARY OF THE INVENTIONOne aspect of the invention relates to a golf ball positioning device suited to accommodate within an internal cavity a stack of golf balls that form a truncated pyramid. The golf ball positioning device includes a hopper and a tray each having a respective surface that extends in a respective plane parallel to each other and each of a dimension to stably self-support the assembled positioning device without toppling on a flat, horizontal surface.
The hopper and tray define an internal cavity when in a closed position that may be constituted by at least a base level and a truncated level, possibly intermediate levels as well. Each level accommodates a layer of golf balls. The tray may have an indentation whose shape complements a shape of the truncated level to facilitate stacking of identical truncated pyramidal positioning devices one atop the other each in an upright orientation.
BRIEF DESCRIPTION OF THE DRAWINGFor a better understanding of the present invention, reference is made to the following description and accompanying drawings, while the scope of the invention is set forth in the appended claims:
As shown in
The hopper may be made from transparent or translucent material, because the inside may be viewed from outside. Thus, prized golf balls, for instance, may be displayed prominently within the hopper. The inside of the truncated pyramidal stack, which is not visible from the outside when the hopper is upright, may have the spacer insert. However, the spacer insert 14 may be removed and still the golf balls will remain in their stacked, truncated pyramidal shape.
The golf ball positioning device may include the tray 12 having an upstanding periphery 20 as shown in
The stack of golf balls are stable for standing upright if arranged in a truncated pyramid, such as in two layers—the top layer having four balls and the bottom layer having eight balls with a spacer. A regular pyramid would have three layers—the top layer being a single golf ball. However, the truncated pyramid of this invention envisions the omission of such a single golf ball so that the layer with four golf balls becomes the top layer, which gives rise to the truncation of the pyramid
Since the top and bottom exterior surfaces of the positioning device are substantially flat that extend in parallel, horizontal planes, identical ones of such positioning devices may be stacked one onto the other, which facilitates storage in a more compact manner than would otherwise be the case.
The hopper 30 and tray 32 in the closed position define an internal cavity in the form of a truncated pyramid. When golf balls fill the internal cavity, the hopper 30 and tray 32 are configured so that the position where golf balls stack within the internal cavity form a truncated pyramid shape.
The hopper 30 has a truncated level 40 for accommodating a truncated layer of golf balls. The tray 32 has a base level 42 for accommodating a base layer of golf balls. The hopper 30 and the tray 32 each have a respective open face. In the embodiment of
The truncated level 40 is smaller in dimension than the base level 42. The tray 32 may have a central indentation 44 that complements the shape of the truncated level 40 of the hopper 30. This allows the truncated level 40 of the hopper shell 30 of one device to be fitted into the indentation 44 of the tray 32 of another identical device so as to snugly fit with each other. Such enables the devices to be stacked on atop the other when the hopper shell 30 and the tray 32 are in a closed position as shown in
The hopper 30 and tray 32 may have dimples or bulges 46 spaced from each other and arranged to either accommodate receiving a golf ball or separating adjacent golf balls in a layer of the stack. The dimples or bulges 46 may each have a curvature that is either convex or concave, depending upon its role in either receiving or separating a golf ball. If the dimples or bulges are formed in the truncated level 40 and the indentation 44, preferable they correspond with each other in location and shape so as to enable the indentation 44 to snugly fit onto the truncated level 40 when stacking identical positioning devices in the closed position as shown in
If desired, an inwardly directed dimple may be arranged in the center of the flatted top of the truncated level 40 of the hopper 30 and a complementary outwardly directed dimple may be arranged in the center of the flattened portion of the indentation 44 of the tray 32. The inwardly directed dimple and the complementary outwardly directed dimple are arranged to mate with their complementary counterparts on identically formed positioning devices when stacked in the manner of
Alternatively, the tray 32 could be symmetric or identical in configuration with the hopper 30. Such could give rise to three layers of golf balls resembling a truncated pyramid when viewed from the top or resembling a truncated pyramid when viewed from the bottom.
The clam shell embodiment of
The hopper 30 and tray 32 are each preferably made of an elastic, resilient material such as rubber or pliable plastic. Preferably, the material has memory.
The peripheral portion of the bottom of the tray 32 immediately surrounding the indentation 44 may be flat, jagged or rounded to define a surface 50 that extends within a plane. The truncated level 40 of the hopper 30 has a top that may be flat, jagged, or rounded to define a surface 52 that also extends in a plane that is parallel to the plane through which extends the surface 50. If either surface 50, 52 is placed on an external, flat horizontal surface, the positioning device is stably supported without toppling over when in the closed position.
While the foregoing description and drawings represent the preferred embodiments of the present invention, it will be understood that various changes and modifications may be made without departing from the spirit and scope of the present invention.
