This application claims benefit of U.S. Provisional Application Ser. No. 61/220,301, filed Jun. 25, 2009, and the entirety of such application is incorporated herein by reference.
This invention relates generally to a system for excavation of a hole, placement of an item in the hole, and backfilling the hole, and more specifically, to a system for digging graves, which may include transport of container such as a casket or vault to the grave site, excavation of a grave for receipt of the container, lowering of the container into the grave, and subsequently backfilling the grave.
Accomplishing the burial of a person's remains can be a labor and/or equipment-intensive endeavor, potentially requiring multiple workers and multiple pieces of equipment. For example, a backhoe or tractor may be needed at the grave site to dig the grave, and a truck and/or trailer may be needed for transport of the backhoe and the casket and/or vault to the vicinity of the grave site. Additionally, multiple workers may be required to operate such equipment, which can result in increased labor costs, personnel issues, etc. Further, use of various pieces of equipment can potentially increase equipment costs, logistics issues, maintenance issues, etc.
Generally, a preferred embodiment of the present invention includes a method and a system for excavation of a hole, placement of an item in the hole, and back filling the hole.
More specifically, at least one embodiment of the present invention includes a system for digging a grave at a grave site, comprising an elongated frame defining a frame opening of an area that is generally at least as large as the area of the grave and that is positioned over the grave site, and a motor that is connected to the frame. Wheels may be connected to the frame to allow for movement of the frame about a surface, with the motor being connected to the wheels for selectively providing motive force to the wheels to move the frame about such surface. Connected to the frame is an excavator configured for generally digging the grave via operation in the frame opening.
The foregoing system for digging a grave may also include a hoist attached to the frame that lifts and lowers a container within the grave.
Also, the foregoing system for digging a grave may include outriggers for stabilizing the frame during operation of the hoist and of the excavator.
Further, the foregoing system for digging a grave may also include at least one container for receiving dirt excavated by the excavator and for holding such dirt as the frame is moved about the surface.
Additionally, the foregoing system for digging a grave may include a generally zero radius turn structure connected to the wheels that allows the frame to make a generally zero radius turn when moving about a surface.
The present invention also includes a method of digging a grave at a grave site comprising positioning an opening, defined by a frame, of an area generally at least as large as the area of the grave over the grave site, and digging the grave via the opening using an excavator connected to the frame. The method further includes lowering a container into the grave using a hoist connected to the frame.
The foregoing method may also include placing dirt generated during the excavation of the grave in a container attached to the frame and dumping the dirt from the container to backfill the grave.
The foregoing, as well as other objects of the present invention, will be further apparent from the following detailed description of the preferred embodiment of the invention, when taken together with the accompanying specification and the drawings, in which:
The accompanying drawings and the description which follows set forth this invention in several of its preferred embodiments. However, it is contemplated that persons generally familiar with digging and excavation equipment and systems will be able to apply the novel characteristics of the structures illustrated and described herein in other contexts by modification of certain details. Accordingly, the drawings and description are not to be taken as restrictive on the scope of this invention, but are to be understood as broad and general teachings.
Referring now to the drawings in detail, wherein like reference characters represent like elements or features throughout the various views, the grave digging system of the present invention is indicated generally in the figures by reference character 10.
In one of various preferred embodiments, grave digging system 10, also referred to herein as “grave digger system 10,” or “system 10,” is self-propelled and is capable of lifting and transporting a container, generally C (
Turning to
Extending outwardly from the front of frame A is a tongue structure, generally T, which allows system 10 to be towed by a tow vehicle (not shown). Tongue T is pivotable about pivot points or pins 14, and includes a coupling, generally C, for attaching tongue T to a tow vehicle. Although not shown, a spring and/or hydraulic or pneumatic cylinder assist could be attached to tongue T to facilitate raising and lowering tongue T during pivoting of tongue T. Frame F includes uprights, generally U, extending upwardly from a base portion B of frame F. The upper ends of uprights U are connected by bridging portions 16, which serve to support a longitudinally extending boom, generally 18, which runs generally the length of frame F. Pivotally connected to uprights U are outriggers, generally O, which may be pivoted about the longitudinal axes of uprights U. Outriggers O each include an upper arm 20a, and a lower arm 20b pivotally connected to the upper arm 20a. An actuator, generally A, such as a hydraulic and/or pneumatic cylinder 22, is provided for moving the lower arm 20b of each actuator A between a lowered position, as shown in
As shown in
Pivoting dirt bins, or boxes, generally 32, are also provided along each side of system 10 and are configured for carrying and dumping dirt, generally D (
Turning now to
In one embodiment, dirt bins 32 are each approximately one cubic yard in capacity. Because a standard burial vault displaces approximately two cubic yards, the one cubic yard capacity of each bin would allow the operator (not shown) to have a good approximation of when an adequate amount of dirt has been discharged into the grave to compensate for the displacement of soil of the vault. When the level of dirt remaining in each bin approximates the height of its sidewalls, generally 60, of each bin 32, the operator will know that an approximate adequate amount of dirt has been backfilled into the grave to compensate for the amount of dirt displaced by the vault. The lids, or cover members, 48 of each bin could then be moved to their position for covering the bins, and such bins 32 could be moved to their generally upright position during moving of system 10 about and/or from the cemetery. Locking mechanisms can be provided (not shown) to lock cover member 48 closed during transport.
In one example of operation, one of various preferred embodiments of system 10 can be operated to accomplish the burial of a person's remains. For example, in the instance where a vault is ready for transport and burial at a grave site, an operator could lock the wheel hubs of the wheels W of system 10 in order that the wheel drive motors are operable to drive the wheels of system 10. During transport of system 10 over the road, as system 10 is towed by a tow vehicle (not shown), the wheels are preferably unlocked, to allow them to freewheel.
After locking the wheel hubs, the operator could proceed to configure system 10 for pick up of the vault V. This can involve system 10 approaching the vault such that the forward end of system 10 is near the vault. The operator may extend the outriggers O for stabilizing system 10 and extend the boom 18 to a position over the vault. Then, using the hoist H, the operator connects the hook 67 to a chain and/or strapping arrangement S configured about the vault for allowing pick up thereof. The operator would activate the hoist to lift the vault, and then retract the boom such that the vault is moved rearwardly within system 10. Once in such position, the vault is lowered onto the cradles 80, which are pre-positioned in place for supporting the vault. As discussed above, the cradles are movable for allowing the backhoe 46, or other excavator, to dig the grave through central opening 40 and for ultimately allowing the vault to be lowered into the grave. Preferably, once the vault is in place resting on the cradles, the vault is fixed in place using straps, chains, ropes, cables, or the like (none shown).
System 10 can then propel itself to transport the vault using its motor M and wheel motors, or, system 10 can be towed by a tow vehicle (not shown) over the road to another location, such as a cemetery. In the event system 10 is to be towed while holding vault V, wheels W can be unlocked to allow them to freewheel during towing. Once system 10 is towed to the desired location, it is detached from the tow vehicle, and its tongue portion T is preferably pivoted upwardly and fixed in such upward position to facilitate the maneuverability of system 10 as it is driven about.
When system 10 is to be operated in its self-propelled mode, the operator may sit in seat 50, and using controls 42, the operator may drive system 10 by manipulating the drive controls in a manner similar to how a bulldozer, skidsteer loader, excavator, etc. is driven. Although not shown, other steering devices such as a steering wheel, electronic steering, etc. could also be used. This driving arrangement, or structure, provides for a generally “zero radius turning” capability, with one control controlling the left side drive wheels, and another control controlling the right side wheels.
If a grave is to be dug, system 10 may be driven to the grave site and positioned such that the center opening 40 thereof is over the location of the grave to be dug. The operator could extend the outriggers O, and also lower dirt bins, or boxes, 32 to their generally horizontal position. The operator can unfasten the vault, by removing such straps, chains, or other fixation devices used for fixing the vault in place during transport. The vault would then be raised by the hoist H such that it was above and clears the cradles. The boom 18 would be extended, such that the vault can be moved outwardly from the central passage 40 and beyond the area of earth where the grave is to be dug. In order to clear central passage 40 for digging the grave, the cradles are moved out of the way on tracks 82, to a position generally removed from the area of earth in which the grave is to be dug.
Once the central passage 40 has been cleared, the excavator, or backhoe, 46 can then be used to dig the grave, with the operator manipulating the controls for the digging bucket to remove the earth necessary to dig the grave. The dirt removed during the digging process is dumped into the dirt bins 32 on either side of system 10 (the lids, or covers, 48 of such dirt bins having previously been opened). In order to maintain weight balance, the operator could, using the backhoe, dump earth into the left side and right side dirt bins 32 in alternating manner once the grave has been dug.
During digging, the vault is preferably positioned slightly above contact with the ground, to thereby keep tension in the hoist system H, such that vault V acts as a counterweight to balance system 10 during the digging operation. Once the grave has been dug, the boom and hoist H are activated to move the vault rearwardly and to then lower it into the grave.
Upon the casket has been placed in the vault V, and the vault covered with its lid, backfilling of the grave is done. The dirt bins 32 are pivoted to the dumping position in order to backfill the grave G with the dirt therein. The operator may use the bucket of the backhoe to pack or tamp down the dirt in the grave to the desired compaction level. Note that prior to moving the bins 32 to the dumping position, the bin covers are preferably closed, and once the desired amount of dirt has been dumped from such bins, the dirt bins are moved to the vertical position as show in
After the burial and backfilling have been completed, the outriggers O can be retracted, and the operator can drive system 10 to another grave site, back to the tow vehicle, etc., transporting any excess dirt in the dirt bins. Once at the tow vehicle, the tongue T can be pivoted to its horizontal, towing position, and recoupled to the tow vehicle. Upon the wheels W of system 10 being unlocked, to allow them to free wheel during towing, and system 10 otherwise secured for towing, system 10 may be towed from the site by the tow vehicle to another location.
It is to be noted that system 10 is not limited to use in digging graves, but could be readily used and configured for use for a variety of other purposes. For example, system 10 could be used for burying other equipment, such as pipes, valves, sensors, etc. Use of system 10 in such instances could potentially afford benefits in labor and/or equipment cost savings.
As can be seen from the foregoing, at least one preferred embodiment of the present invention includes a system for digging a grave at a grave site, and includes an elongated frame which defines a frame opening of an area generally at least as large as the area of the grave and that is positioned over the grave site. A motor is connected to the frame, and wheels connected to the frame allow for movement of the frame about a surface, with the motor being connected to the wheels for selectively providing motive force to the wheels to move the frame about such surface. Also connected to the frame is an excavator configured for generally digging the grave via operation in the frame opening.
The foregoing system for digging a grave may also include a hoist attached to the frame that lifts and lowers a container within the grave.
Also, the foregoing system for digging a grave may include outriggers for stabilizing the frame during operation of the hoist and of the excavator.
Further, the foregoing system for digging a grave may also include at least one container for receiving dirt excavated by the excavator and for holding such dirt as the frame is moved about the surface.
Additionally, the foregoing system for digging a grave may include a generally zero radius turn structure connected to the wheels that allows the frame to make a generally zero radius turn when moving about a surface.
As can also be seen from the foregoing, at least one preferred embodiment of the present invention includes a method of digging a grave at a grave site comprising positioning a opening, defined by a frame, of an area generally at least as large as the area of the grave over the grave site, and digging the grave via the opening using an excavator connected to the frame. The method further includes lowering a container into the grave using a hoist connected to the frame.
The foregoing method may also include placing dirt generated during the excavation of the grave in a container attached to the frame and dumping the dirt from the container to backfill the grave.
