The present invention relates to mechanisms for holding or guiding a fence post (or other type of post) in an essentially vertical orientation, facilitating the driving of the post into the ground. More particularly, the invention disclosed herein relates to devices holding or guiding the post vertically, in a relatively loose manner so that the downward driving force does not damage the device, and so that the device can readily be removed part way through the post-driving activity so that the driving can be completed without endangering the device.
Post driving and pile driving devices have been known for years.
U.S. Pat. No. 6,719,261 issued to Wadsworth (entitled Post Support Apparatus) discloses a mobile apparatus for supporting a metal post while it is being driven into the ground, utilizing a base plate having a tubular guide member for holding the post in a steady condition while the post is being driven into the ground. The post is insertable endwise into the tube and is engageable with the ground through a through-opening cut in the base plate; one embodiment includes an aperture having a T-shape, for insertion of a T-post through the base plate. As a user stands upon or beside the base with his feet positioned on opposite sides of the through-opening, both of his hands are free to use a driver to drive the post into the ground.
U.S. Pat. No. 6,517,294 issued to Vreeland (entitled Apparatus for Installing a Silt Fence) discloses a stake driving device including a vertical tube within another tube which is rigidly connected to the side of a tractor, for positioning fence stakes point-down towards the ground while being driven into the ground. With the tractor stopped at the desired place for fence stake placement, the user inserts a stake point-down through the aligned slot openings of the inner tube and outer tube, which are located beneath a hydraulic piston ramming the stake into the ground.

U.S. Pat. No. 10,745,880 issued to West (entitled Guided Multiple Pile Driver System) discloses a system for simultaneously driving multiple piles into the ground to create A-frame type structures that are anchored by piles running at angles to one another and to the ground. The system comprises a guide assembly and an actuator for driving the piles into supporting ground at the same time. The actuator may engage slots or teeth in the pile to drive them into the ground and/or may apply torque and downward pressure. The guide assembly may be a guide housing having open ends (the lowermost in contact with the ground), preventing escape of the piles while being forced into the ground, and guiding the orientation of the piles being driven into the ground.

U.S. Pat. No. 8,230,944 issued to Thiem (entitled Post Alignment Tool) discloses a tool known as a Post Pounder, having a paddle-like configuration including a plate having an aperture sized to closely accept insertion of T-post. The tool is used to apply radial torque to a post which has been driven into the ground, for aligning the T-post in an orientation similar to other nearby posts for a fence.
The invention disclosed herein is essentially an apparatus for positioning a fence post (or other post) vertically for manually driving it into the ground, comprising (including) a collapsible mobile tri-pod straddling a stabilizer paddle providing additional stability to the tri-pod while providing an adjustable aperture loosely capturing the post to position it vertically while the user commences driving the post into the ground. The invention also includes a way to easily remove the apparatus from the partially-driven post, so that the user can complete the driving without fear of an errant down-stroke of driving force that would impact and damage the apparatus.
One primary benefit of the disclosed invention is that the apparatus is readily transportable by hand, allowing the user to carry it and use it in places not readily reachable by vehicle.
Another benefit of the apparatus is that it is easily re-configured from its compacted travel/storage configuration to its free-standing use configuration, without tools.
Another benefit of the apparatus is that it holds and guides posts of different thicknesses or dimensions, enabling the user to drive it into the ground without another person's assistance.
Another benefit of the apparatus is that it can be readily removed from the partially-driven post and set aside, so that the user can complete the driving without fear that an errant down-stroke of driving force will impact the apparatus and damage it.

In general, the invention disclosed herein includes (comprises) an apparatus expandable from a compact transport configuration to a free-standing use configuration for positioning a fence post essentially vertically to allow the user to manually drive it into the ground. In one general embodiment, the apparatus includes a compactable tri-pod-like assembly including an assembly head having means for connecting the legs.
Connecting to the assembly head (40) are:
For bracing the tri-pod and holding the post in an essentially vertical orientation awaiting driving, there is also a stabilizer guide member (60) comprising:
In one specific embodiment of the invention, the apparatus described herein includes the pivotable 1st and 2nd support legs oriented to pivot apart in substantially the same plane. The 3rd pivotable support leg may then be oriented to pivot outwardly in a plane essentially perpendicular to the plane of the pivotable 1st and 2nd support legs.
The assembly head may further comprise a pair of essentially parallel front and back support plates (41 and 46), each support plate including a lower hole (43 and 48) aligned with a corresponding lower hole of the other support plate. Each of the pivotable 1st and 2nd support leg's apex ends may have a cross-sectional area defined by the outer surfaces, and each apex end of the respective 1st and 2nd support legs may further comprise a converging tip region (12 and 22) including a terminal tip (14 and 24). One surface of the support leg may also include a diagonal planar cutaway (13 and 23), reducing the cross-sectional area as the tip is approached, thereby essentially converging the apex end of the support leg into a narrowing tip end.
The apex end of each respective support leg also includes a lower bore (16 and 26) aligned with the aligned lower holes of the front and back support plates; each respective lower bore and lower holes receive a hinge pin (51 and 52) enabling the support leg to pivot from a vertical compacted position outwardly to a free-standing use position.
The pair of essentially parallel front and back support plates may further include an upper hole (42 and 47) aligned with a corresponding upper hole of the other support plate. Each of the converging tip regions of the respective pivotable 1st and 2nd support legs may further include an upper bore (15 and 25) aligned with the upper holes and near the tip, and situated along a plane closely parallel to the diagonal planar cutaway. Each respective upper bore and upper holes may receive a removable fastening pin so that, when a support leg is in the vertical compacted position, the upper holes of the opposing support plates are aligned with the upper bore near the tip, so that inserting the fastening pin therethrough locks the leg in the compacted position; on the other hand, inserting the fastening pin through the upper holes in the support plates when the leg is in the free-standing position chocks against the outer surface of the leg near its tip, to fix the leg in the free-standing position.
The removable fastening pin may also include a fastener end configured to accept a removable fastener. The removable fastener may be selected from the group consisting of a nut for external threading, a cotter pin for a transverse aperture through the fastener end, and/or other removable fasteners, and combinations thereof.
The apparatus may further include angulation adjustment means for adjusting the angulation of the stabilizer guide member, thereby adjusting the size of the aperture sized to accept insertion of the unclaimed fence post. The size of the opening of the post-accepting aperture (69), on the guide end of the stabilizer guide member, is largest when the stabilizer guide member is in a horizontal orientation. The size of that opening changes however, as the stabilizer guide member is moved away from that horizontal plane. The perceived diameter of the typical circle or oval, when viewed from directly above or below the opening, decreases as the stabilizer guide member approaches a more vertical orientation. The user may adjust the orientation of the stabilizer guide member to decrease that aperture's vertical opening to the extent desired to hold the post in an essentially vertical orientation for commencing driving. Moreover, when the stabilizer guide member is in a diagonal orientation, the edge of the aperture may be set to touch the post on opposite sides, with one touch-point higher than the other touch-point, thereby providing additional stabilizing guidance. When ready to remove the apparatus, the user can then re-adjust the orientation of the stabilizer guide member to increase the perceived diameter of the aperture, so that the apparatus can be lifted off the partially-driven post for completion of driving.
The angulation adjustment means may be selected from the group consisting of: (1) means of varying the connection point where the stabilizer end of the stabilizer guide member pivotably connects to the 3rd support leg, or (2) means for varying the height of the lower connection end of the stabilizer support downstanding from the assembly head, or (3) means for varying the length of the support legs, and combinations thereof.
The means of varying the connection point, where the stabilizer end of the stabilizer guide member pivotably connects to the 3rd support leg, may involve the 3rd support leg including a plurality of periodically spaced bore-holes (not shown); and the stabilizer end may include a longitudinal slot or periodically spaced holes (not shown) in cooperating relationship with the bore-holes for receiving a fastening means extending therethrough for firmly connecting the stabilizer end (64) and the 3rd support leg at a location yielding the desired angulation of the stabilizer guide member.
The means for varying the height of the lower connection end of the stabilizer support downstanding from the assembly head may involve the stabilizer support including an elongate vertical sleeve (44) fixed between the support plates (41 and 46), and telescopically accepting a strut (54) affixed therein and downstanding therefrom. Both the sleeve and the strut may further include a plurality of aligned and periodically spaced throughways (not shown) accepting insertion of a fastener therethrough to vary the length of the stabilizer support.
The means for varying the length of the support legs may involve each of the support legs defining a hollow lumen telescopically accepting an extender (19, 29 and 39) therein. Both support leg and extender may further include a plurality of aligned and periodically spaced throughways (not shown) accepting insertion of a fastening means after the extender is extending beyond the lumen, to vary the length of the respective support leg.
One specific embodiment of the apparatus, expandable from a compact transport configuration to a free-standing use configuration for positioning a fence post essentially vertically to allow the user to manually drive it into the ground, includes a compactable assembly comprising:
Additionally the pair of essentially parallel support plates may further include an upper hole aligned with a corresponding upper hole of the other support plate. each of the converging tip regions of the respective pivotable 1st and 2nd support legs may further include an upper bore aligned with the upper holes and near the tip, and along a plane closely parallel to the diagonal planar cutaway, each respective upper bore and upper holes receiving a removable fastening pin. When a support leg is in the vertical compacted position, the upper holes of the opposing support plates are aligned with the upper bore near the tip, so that inserting the fastening pin therethrough locks the leg in the compacted position, while inserting the fastening pin through the upper holes in the support plates when the leg is in the free-standing position chocks against the leg to fix the leg in the free-standing position.
The angulation adjustment means for adjusting the angulation of the stabilizer guide member comprises means of varying the connection point where the stabilizer end of the stabilizer guide member pivotably connects to the 3rd support leg includes the 3rd support leg having a plurality of periodically spaced bore-holes. The stabilizer end may include a longitudinal slot or periodically spaced holes in cooperating relationship with the bore-holes for receiving a fastening means extending therethrough for firmly connecting the stabilizer end and the 3rd support leg at a location yielding the desired angulation of the stabilizer guide member.
Alternatively, the angulation adjustment means for adjusting the angulation of the stabilizer guide member may include means for varying the height of the lower connection end of the stabilizer support downstanding from the assembly head comprising the stabilizer support including an elongate vertical sleeve fixed between the support plates and telescopically accepting a strut affixed therein and downstanding therefrom, both the sleeve and the strut may further include a plurality of aligned and periodically spaced throughways accepting insertion of a fastener therethrough to vary the length of the stabilizer support.
Alternatively, the angulation adjustment means for adjusting the angulation of the stabilizer guide member may include means for varying the length of the support legs, including each of the support legs defining a hollow lumen telescopically accepting an extender therein. Both support leg and extender may further include a plurality of aligned and periodically spaced throughways accepting insertion of a fastening means after the extender is extending beyond the lumen, to vary the length of the respective support leg.
Although the apparatus may assemble the apparatus in a number of manners or sequences, the following has proven efficient:
If you want the apparatus to be in the compacted travel/storage configuration, undo steps (5) and (6) above; and in step 3 above, pivot the 1st and 2nd support legs together, then insert the fastening pin through the upper holes of the front and back support plates aligned with the upper bore, to lock each respective 1st and 2nd support leg in a narrow stance; then pivot the 3rd support leg inwardly.
