Not applicable.
The present invention relates in general to impact tools, and, more particularly, to snow stake drivers that allow for fast, safe, and convenient placement of snow stakes at controlled and/or predetermined depths—even in soil with aggregate and/or rocks, including, for example, areas proximate to roads and/or the end of driveways. The snow stake drivers of the present invention are suitable with, for example, residential, commercial, and/or industrial snow stakes.
Impact tools and drivers have been known in the art for years and are the subject of a plurality of patents and publications, including: U.S. Pat. No. 10,774,560 entitled “Driveable Stake Member,” U.S. Pat. No. 5,934,139 entitled “Bi-Directional Impact Tool,” U.S. Pat. No. 5,538,302 entitled “Article Handling Tool,” U.S. Pat. No. 4,483,058 entitled “Impact Hammer Elbow Tool,” U.S. Pat. No. 4,101,088 entitled “Manual Impact Stake Driving Apparatus,” U.S. Pat. No. 3,747,690 entitled “Jack Hammer,” U.S. Pat. No. 3,712,389 entitled “Post Driver,” United States Patent Application Publication Number 2011/0198104 entitled “Stake Driver,” United States Patent Application Publication Number 2008/0257113 entitled “Stake Driver,” and United States Patent Application Publication Number 2004/0154812 entitled “Stake Driver Hand Tool”—all of which are hereby incorporated herein by reference in their entirety including all references cited therein.
U.S. Pat. No. 10,774,560 appears to disclose a drivable stake for attachment to an article that includes an elongated stake having a first end section that terminates at a first end and a second end section that terminates at an opposing second end. The elongated stake has impact drive shoulders and a stake plate that is coupled to the elongated stake and in contact with the impact drive shoulders. A coupling member surrounds the elongated stake and includes an opening for attachment to the article. A hollow impact drive member slidingly travels along the second end section of the elongated stake for striking the stake plate and driving the first end section into the ground. The stake includes a fastener for coupling the impact drive member to the elongated stake during a driving action and for locking the impact drive member in place relative to the elongated stake in a locked position.
U.S. Pat. No. 5,934,139 appears to disclose a bi-directional impact tool that includes a hollow tube member and a shaft slidably received by the hollow tube member in a telescopic relationship. The hollow tube member extends along a longitudinal axis and has a first end and a second end disposed opposite the first end. The shaft extends longitudinally along the longitudinal axis and has a working end disposed exteriorly of the hollow tube member for engaging the workpiece and a striking end disposed opposite the working end and interiorly of the hollow tube member. Moving the hollow tube member in a first direction so that the first end collides with the striking end while the working end is engaged with the workpiece imparts a first impact force to the workpiece in the first direction. Moving the hollow tube member in a second direction opposite the first direction so that the second end collides with the striking end while the working end is engaged with the workpiece imparts a second impact force to the workpiece in the second direction.
U.S. Pat. No. 5,538,302 appears to disclose an article handling tool for pushing, pulling and manipulating articles on the bed of a covered or capped pick-up truck and is defined by an elongated pole having a hand grip at one end and a push-pull blade at an opposite end. The opposite end also includes a retractable loop which can be housed within the pole in an unobtrusive inoperative position yet can be readily withdrawn from a chamber of the elongated pole and utilized to encircle or lasso an article. In this manner the loop end and/or the blade allows the article handling tool to be utilized by an individual to manipulate articles of any shape or size seated upon the bed of a covered pick-up truck without the effort and hazard involved heretofore as individuals necessarily climbed into and moved about in the cramped cargo area of such covered pick-up trucks.
U.S. Pat. No. 4,483,058 appears to disclose a simplified, impulse-type pulling and installing tool for appliances such as electrical connector elbows which in use generate a sharp impact force to facilitate quick, safe elbow manipulation even under electrical load, thereby reducing the probability of flashover. In preferred forms, the tool includes an elongated rod having workpiece-engaging apparatus adjacent one end thereof, with tubular hammer means telescoped over the rod and reciprocably slidable along a portion of the length thereof. The hammer includes structure defining a pair of hammering surfaces respectively located adjacent the opposed ends of the hammer, and the rod is moreover provided with anvil means secured thereto and oriented for engagement by the hammering surfaces when the hammer is slid along the rod. A pair of such hammering surfaces are provided, which are cooperatively oriented relative to the hammering means, so that fore and aft impact forces can be developed along the length of the rod as desired. In particularly preferred forms, the anvil means is secured to the rod within the bore of the hammer means, and presents a pair of opposed anvil surfaces respectively engageable by corresponding, internal hammering surfaces on the hammering means.
U.S. Pat. No. 4,101,088 appears to disclose an improved manual impact apparatus for driving a stake of the type having a head at one end thereof, which is characterized by a slidable sleeve having oppositely disposed and facing impact stops therein to confine the stake head therebetween during driving or pulling, whereby the stake may be longitudinally propelled in response to impact between one of the impact stops and the stake head.
U.S. Pat. No. 3,747,690 appears to disclose an improved manually actuated self-energizing jack hammer or driver useful as a demolition tool, a compactor, a post or pile driver, a digging tool and the like, composed of an inner anvil tube or barrel receiving a post or pile therein or mounting a tamper, a breaker, a cutter, a digger or the like tools and a tubular ram or hammer telescoped over and guided on the barrel with a recoil spring between the anvil and hammer for lifting the ram after it delivers a hammer blow to the anvil barrel. The inner tube or anvil barrel separates and insulates the driver member such as a fence post or tool from contact with the hammer ram and at the same time guides the ram to insure maximum direct delivery of force from the ram to the tool or post. Handles are provided on the ram for convenient grasping by a single operator to impart a rhythmic reciprocation to the ram aided by the recoil spring to deliver maximum impact blows through the anvil barrel to the tool or post with minimum manual effort. The telescoped barrel tube and ram tube are preferably non-circular in cross-section to prevent relative rotation of the tubes and a heavy hard steel hammer head is secured in the open top of the ram tube preferably in non-mating relation to provide an air vent. The guide tube or barrel also preferably has a heavy hard steel head on the top end thereof providing an anvil receiving the blows from the hammer head. A lock bolt is provided to selectively hold the tubes in telescoped relation.
U.S. Pat. No. 3,712,389 appears to disclose a tubular post driving member that telescopes over the post and has an upper end plate to deliver impact to the top of the post. The driving member has sets of handle sockets at different elevations and these sockets receive removable handles in either 180 degree or 90 degree spacing circumferentially of the post to permit driving of the post in different situations by two workers or one worker. Additional hand grips are provided for erecting the post and driver and for transporting. An adjustable depth gage may also be included on the driver.
United States Patent Application Publication Number 2011/0198104 appears to disclose a stake driver for driving wood stakes into a soil that has a rectangular hollow housing having an open top and an open bottom. The bottom portion is configured for receiving at least a part of the wood stake therein, while an elongated driving shaft extends from an interior of the housing upwardly above a top edge of the housing. The upper part of the driving shaft is configured for engagement by a power transmitting tool, such as for instance a jack hammer. A driving pad is secured to a bottom end of the driving shaft transversely to the longitudinal axis of the housing. At least one hammer plate is secured, through connection to a shaft sleeve, to the driving shaft above the driving pad. The hammer plate and the driving pad are each configured to move in an axial direction inside the housing and transmit a hammering force to the wood stake. The hammering force is partially absorbed by a compression spring positioned between the hammer plate and the driving pad.
United States Patent Application Publication Number 2008/0257113 appears to disclose a manually operated stake driver that has a slide hammer and guide. The guide is fitted with a receiver that captures and guides the stake. The slide hammer provides percussion force directly to the stake by extending into the receiver when the slide hammer is actuated. The slide hammer may have a weight attached or incorporated into a handle to provide additional force to the stake when actuated. In one embodiment, the stake driver may be designed to be used while the operator is standing and to drive stakes into the ground.
United States Patent Application Publication Number 2004/0154812 appears to disclose a stake and post driver having a sleeved construction topped with an expanded impact head. The stake driver body is provided with a concavity for receiving an exposed end of the stake or post to be driven. The concavity is sized and shaped to receive the exposed end of the stake along a length sufficient to grip and support the stake or post during the entirety of the driving operation. The impact head is sized and configured to provide an enhanced “sweet spot” targeted by the user, thereby reducing the requirement for essentially total accuracy in exactly delivering a significant driving impact from a manual driver such as a sledge hammer, mallet or other hand-held mechanical driving means to the typically small target of the exposed end of the stake or post to be driven. One or more spacers are provided to be removably installed in the stake driver, the spacer having a receiving recess for supporting a stake against substantial lateral motion during driving installation of a stake or post.
While the above-identified patents and publications do appear to disclose various impact tools and drivers, their configurations remain non-desirous and/or problematic inasmuch as, among other things, none of the above-identified drivers appear to facilitate fast, safe, and convenient placement of snow stakes at controlled and/or predetermined depths—even in soil with aggregate and/or rocks, including, for example, areas proximate to roads and/or the end of driveways.
These and other objects of the present invention will become apparent in light of the present specification, claims, and drawings.
