THE GARDEN ~IOLE DIGGER
The present invention relates to a hand operated garden hole digging device.
Various types of hand operated digging devices are presently used in the garden. The garden shovel and the garden hoe are representative of some of these devices. They are made from rigid material, have a flat or slightly curved surface of varying sizes for lifting or scooping dirt from the ground and a handle extending from the lifting surface of varying lengths, This type of garden digging device has several disadvantages. The gardener who wishes to dig a hole in order to transplant a small potted plant or plant a garden bulb is forced to dig a large hole in the area of the transplant site in order to dig to the required depth. This is because the nature of the lifting surface does not allow the dirt to be removed vertically, but almost horizontally, otherwise it falls off of the surface.
This would be a concern to those gardeners who have a well groomed lawn and forced to rip it up in order to transplant a few plants.
Another disadvantage of this type .is time involved in digging a hole of any depth, let alone of sufficient depth to transplant most plants or bulbs. It is quite time consuming to dig a larger area in order to get a hole deep enough, especially if one wants to transplant several plants or bulbs.
Another disadvantage of this type is the work and subsequent strain involved in digging a hole. In order to dig a hole with this type of tool at least three times as much dirt must be displaced. This requires extra lifting and strain especially for more elderly gardeners.
Another type of hand powered hole digging device is available for use by gardeners. This hand held device is cone shaped and is available in one size. The operator forces the cone into the ground and lifts it straight upward removing the dirt left in the hole.
One disadvantage of this type is that the operator must generate all the torque necessary with their hand. This is especially difficult to do in hard soil or sod.
Another disadvantage of this type is that the device can only dig one size of hole.
I Another type of hand powered hole digging device is used by ¦ 50 golf course operators. This device bores a cylindrical hole of standard size into the golf course.
::
~a~a73 -One disadvantage of this type is tha-t the hole created is always the same size and the hole is suited for golf courses.
This rnay be ideal for golfers but does not take into consideration the varying needs of gardeners.
Another disadvantage of this type is that the device is extremely unwieldy for gardeners.
It is desirable to have a light, convenient garden hole digging device that can dig various sizes of holes into the earth without unnecessarily tearing up grass or even adjacent plants or bulbs, is capable of lifting dirt cleanly, regardless of the angle of the device, having a mechanism to quickly change the size of the digging cup, having a mechanism for ejecting the dirt once it is lifted out of the ground, is easy to operate and is time and energy efficient.
The present invention consists of a rigid cylindrical cup, open at the bottom, a rigid flat base above the cup and to which the cup is attached, and a rigid handle attached to the base and extending straight up from the base.
The cylindrical cup can be easily removed from the base to which it is attached. It has 3 rigid spikes that protrude upward from the sides of the cylinder and break the plane of the base, rising far enough through the base for a removable hair pin to be inserted in a hole in each spike to prevent the cup from becoming detached from the base.
The cylindrical cup has a jagged cutting edge along the circumference of the bottom of the cup to facilitate easy penetration of soil if the cup is rotated.
The base has several specifically measured holes in order to attach cups of varying sizes. These sizes are 3", 3 1/2" and 4".
The handle extends a sufficient distance vertically such that when the hole digger is resting on the surface of the earth the handle can be grasped comfortably from a standing position without unreasonable bend in the posture of an average human being.
~lu~73 The handle further extends horizontally at the point at which it is grasped thereby forminy handgrips in order to allow for the hole digyer to be grasped by two hands.
1'he handgrips extend a suitable length from the centre of the shaft of the handle such that the operator can apply sufficient force to each handgrip to generate enough downward force and torque for the cup to be driven into the earth with a minimum of strain on the operator.
The operator when applying the necessary force and back and forth rotations to the handgrips creates small rotations of the cylindrical cup thereby allowing the jagged edge of the cup to be ground into the earth.
The cylindrical cup is of sufficient height to bore a hole into the earth of sufficient depth that is useful to the operator.
The cylindrical cup is of sufficient diameter to bore a hole into the earth of sufficient width that is useful to the operator.
There exists more than one cylindrical cup of varying sizes to facilitate the boring of holes of sufficient width and depth to satisfy the operator.
There exists an internal mechanism to aid in the lifting of soil from the ground and the subsequent ejection of soil from the hole digger.
The internal mechanism is comprised of a rigid flat surface located wlthin the cup sp~nnlng most of the diameter of the cup but only a fraction of the height of the cup. A rigid rod is attached to the flat surface and extending through the centre of the base deep into the shaft of the handle.
The rod has a rigid extension through the side of the shaft of the handle. This extension is sufficient to allow the operator to place their foot upon it.
There is a hole in side of the shaft of the handle to allow the extension of the rod to move freely vertically while not jeopardizing the structural rigidity and integrity of the shaft of the handle.
The movement of the flat surface of the internal mechanism corresponds to the movement of the rod and the rigid extension of ~ 1 ~ 7 ~ 7 3 the rod. If the extension is fcrced downward then the surface is forced downward through the height/length of the cylindrical cup thereby forcing the contents of the cylindrical cup to be ejected. -The rigid extension through the shaft of the handle is at a comfortable height so as to prevent strain of the operator as they apply downward force on the extension with their foot.

Figure 1 is a front view of the hole digging device; and Figure 2 is a side view of the hole digging device shown in Figure 1; and Figure 3 is a perspective view of the hole digging device shown in Figure 1; and Figure 4 is a front view of the internal mechanism of the hole digging device shown in Figure 1; and Figure 5 is a perspective view of the internal mechanism of the hole digging device shown in Figure l; and Figure 6 is a side view of the cylindrical cup of the hcle digging device shown in Figure 1; and 30Figure 7 is a perspective view of the cylindrical cup of the hole digging device shown in Figure 1.

The handle is permanently attached to the base from above and is comprised of a shaft 42, and two handgrips 48, and 50.
There is a bend 44, and 46 in the handle at the point at which the handgrips are joined to the shaft. These may be arcuate even though they are shown in the figures as being angular.
The internal mechanism 52 rests,inside the framework of the hole digger. It is comprised of a flat surface 54 which is attached to a straight rod 56 that extends upward from the surface. There are two foot levers 58, and 60 that extend horizontally from the straight rod. These are designed to protrude through the shaft of the handle of the hole digger in order to operate the internal mechanism.
There is a hole 62 in the shaft of the handle through which the foot lever protrudes. The hole is of sufficient size to permit the internal mechanism to move freely upward or downward within a given range.
The purpose of the garden hole digger is to provide an efficient and easy way to dig a hole for potted plants and garden bulbs, as an example. The hole digger is rested upon the ground with the hand grips held firmly. By applying a downward force ~0 coupled with lateral rotations of the handle the cylindrical cup is driven into the earth. As the cup fills with dirt the flat surface of the internal mechanism is pushed upward. The hole digger is forced downward until the base is almost level with the ground. The corresponding position of the flat surface of the internal mechanism is at the top of the cylindrical cup.
Once the cup is filled apply an upward force on the handgrips to lift the hole digger out of the ground. A clean, neat hole of the desired size remains.
To discharge the dirt from the hole digger place the hole digger directly above the desired location. Place your foot on one of the foot levers that extend from the internal mechanism.
Apply a downward force upon the foot lever forcing the flat surface of the internal mechanism downward through the cylindrical cup and dumping the contents on the ground.
To change the cylindrical cup in order to use one of a more appropriate size simply remove all three hair pins that are inserted in the holes in the spikes of the cups. Remove the old cup from the base and insert the new cup in the corresponding preset holes.

There are two bends 72 and 74 which may be arcuate but are shown in the Figures as angular.
The rigid packing surface effectively creates two triangular wedges at the top of the cup. As the hole digger travels deeper into the earth the dirt that enters the cup is forced into the wedges at the top of the cup. This causes the dirt to be packed tightly into the cup such that the dirt can be lifted cleanly out of the hole.
Although only a single embodiment of the present invention has been described and illustrated, the present invention is not limited to the features of this embodiment, but includes all variations and modifications within the scope of the claims.
