Definitions
- the present invention relates to the field of temporary braces for supporting and maintaining a post in a desired angular orientation, typically vertically, with respect to the ground.
- United States patent number 6,684,580 in the name of David Hull discloses an apparatus for supporting and stabilizing a post.
- the invention uses a box shaped collar that is slid over the post, and the collar has a series of cam levers that when operated, clamp against the post to secure the collar to it.
- the boxed shaped collar may have one of its side panels removable, or hingedly attached, thereby eliminating the need to slide the collar over one end of the post.
- the collar has a plurality of legs attached to it that support and hold the post in proper orientation when erected.
- the problems associated with this device are that the collar has limited applicability to the size and shape of the posts it can operate on.
- the size of the post can only fall within a relatively narrow range in order for it to be able to be engaged by the locking cams, and the boxed shape collar is more difficult to use on a post with a cross section other than square e.g. circular. Also because the lever cams directly engage with the post to be braced, pressing against it, there is potential for the post to be marked or indented where the cam has engaged with it, thereby potentially degrading the external appearance of the post.
- the present invention is directed to a post brace comprising a clamp formed from first and second parts, adjustable locking means interengageable with the first and second parts, and a plurality of legs that are attached to the first and second parts wherein the first and second parts may be placed on the post at a desired location relative to the post's length, and the adjustable locking means are adapted to force the first and second parts towards one another thereby clamping the post, and wherein at least one of the legs has adjustment means that permits the angle of the post being braced to be adjusted into a desired orientation relative to the ground when the post is erected.
- first and second parts are substantially L shaped, such that when each is in its respective use position, they substantially surround the post and form a collar around the post.
- each arm of the L shaped first part has an outwardly directed tab
- each arm of the L shaped second part has an outwardly directed tab orientated to oppose a corresponding tab of the first part, thereby creating two pairs of opposing tabs such that when the first and second parts are in their use position, each pair of opposing tabs may receive the adjustable locking means, and the first and second parts are then forced into gripping engagement with the post by tightening the adjustable locking means.
- the adjustable locking means comprises a shaft with a thread at one end and a plurality of coplanar diametrically opposed outwardly extending pairs of lugs that are spaced along the length of the shaft.
- each tab in each pair of opposing tabs has a recess which is capable of receiving the shaft with one of the lugs in abutment with sides of the tab defining the recess, and its opposing tab has a recess or opening for receiving the threaded end of the shaft, such that when the first and second parts are in their use position, the clamp may be tightened on the post by tightening a nut on the thread.
- each outwardly extending tab abutting a lug has retaining means to hold the lug in a preferred orientation relative to the tab, thereby preventing the shaft from turning when the nut is turned to either tighten or loosen the clamp.
- one or more of the legs comprises a foot which is capable of being fastened to the ground so as to provide a pivot point about which the post can pivot when erected.
- the adjustment means is adapted to vary the length of a leg.
- the adjustment means comprises a height adjustable foot.
- the leg is pivotally connected to the respective foot.
- At least one leg is pivotally connected to the clamp.
- the first part comprises two of the legs and the second part comprises one of the legs.
- a post is erected and braced in accordance with the present invention by firstly preparing a hole in the ground to receive the post, positioning the post to be erected and braced relative to the hole, measuring an appropriate length along the post to position the post brace such that when the post is erected, a desired portion of the post enters the hole in the ground, placing a temporary stand in a position remote from the hole, placing the first part on the temporary stand such that the feet are in contact with the ground and orientated towards the hole in the ground, laying the post on the first part so that it is supported by the stand off the ground laying the second part over the post, adjusting the locking means to clamp the post, pivoting the post about the two feet of the first part that are in contact with the ground, thereby allowing the end of the post to enter the hole in the ground and the at least one leg of the second part to make contact with the ground on the opposite side of the hole in the ground, creating a tripod, setting the angle of the post relative to the ground by the adjustment means.

- Figure 14 is a perspective view of the clamp fully assembled on the post prior to erection.
- Figure 15 shows a view of a person erecting the post by pivoting the post and brace about the feet attached to the first part of the clamp.
- Figure 16 show an alternative embodiment where the leg attached to the second part is hingedly attached so that it my be swung into a more convenient position to account for nearby obstructions and voids such as a wall, adjacent post, rock or slope etc.
- Figures 17 and 18 show perspective views of this alternative embodiment in use near a wall.
- Figure 19 shows a plan view of yet another alternative embodiment where the leg is angled so at to avoid nearby obstructions.
- Figures 20 and 21 show yet another alternative embodiment where the leg and its associated height adjustment shaft is pivotally attached to the foot to ensure the foot pad remains in full contact with the ground while the post is being prepared for erection, and when the post is being rotated about the feet attached to the first part and swung into position in the hole in the ground.
- FIG. 1 shows a post brace 1 according to the present invention.
- the post brace has a clamp 3 comprising a first part 5 and a second part 7.
- the first part 5 having two legs 15 attachable to it which terminate at foot connectors 17 which in turn are each attached to a shaft 21 which in turn is connected to a foot 19.
- the height at which a foot connector 17 attaches to a shaft 21 is adjustable by turning 22 or 32.
- a single leg 15 is attached to the second part of the clamp 7 and terminates at a foot connector 17 which in turn is connected to a shaft 21 which in turn connects to a foot 19.
- all three legs can have their heights independently adjusted by turning either 22 and/or 32.
- the adjustable locking means comprises a shaft 26 with a threaded end 16 and a plurality of outwardly extending lugs pairs 14 that are spaced along the shaft with a terminating pair of lugs at the extreme end of the shaft opposite to the threaded end 16.
- the plurality of lug pairs enable the clamp assembly 3 to accommodate a wide range of post crass-sectional shapes and sizes.
- the clamp 3 is attached to larger posts by utilizing the most suitable lug pair further away from the threaded end 16, while the clamp 3 can be attached to smaller sized posts by utilizing a suitable lug pair nearer to the threaded end 16.
- the plurality of lug pairs on the adjustable locking means 13 enable the clamp 3 to clamp onto a wide variety of posts with various cross sections.
- Figure 2 shows the first part of the clamp which is substantially L-shaped and features a pair of outwardly extended tabs 9 which each feature a slot 10 which is capable of receiving a portion of the shaft 26 of the locking means 13.
- a pair of recesses 18 are located adjacent the slots 10, that are capable of receiving a pair of lugs 14, and holding them in desired orientation with respect to the first part 5.
- a pair of leg connector means 20 is also provided.
- Figure 3 shows the second part of the clamp 7 which also features an L-shaped body and a pair of outwardly extended tabs 11 which each feature opening 12 for receiving the threaded end of the shaft 26 of locking means 13.
- a single leg connector means 20 is shown.
- the foot connector 17 connects to the end of each leg 15.
- the connector has an opening 6 which has an inner thread 4 that co-operates with the external thread of shaft 21.
- Shaft 21 is best shown in Figure 10 and comprises an elongate circular body with a hexagonal section 22 at one extreme end, a threaded portion 30, and another hexagonal section at section 32 at an opposite end nearer the foot.
- the end of the connector 21 opposite the hexagonal end 22 is inserted into the foot.
- the lower sidewall of hexagonal section 32 abuts against the top of the foot.
- a recess 28 is formed in the shaft and rests wholly within the foot when connected.
- foot 19 has a vertical tubular section 37 that receives the end of the foot connector 21 with the recess 28.
- the end of 21 is inserted in the tubular section 37 and a lock bolt is screwed into lock bolt receiving means 35.
- the lock bolt is sufficiently long so that when fully tightened in 35, the end of the lock bolt extends inside the interior diameter of the tubular extension 37 and rides in the recess 28, thereby allowing the foot to be rotatably attached to the shaft 21.
- the foot 19 may have openings 39 for receiving fastening means such as tent pegs or the like for fastening the foot to the ground.
- the foot 19 has a pivotally attached circular connector 33. This allows the maximum area of the foot to remain in complete contact with the ground while the brace is being assembled on the post, and while the post is being pivoted into its erect position.
- Stand 23 has an L-shaped section at the top that is pivotally coupled so as to accommodate the substantially L-shaped section of the first part 5 of the clamp 3.
- the first part 5 is laid upon the stand so that its legs 15 and associated feet 19 are in contact with the ground, and pointing back in the direction of the hole in the ground.
- the post is then laid upon the first part 5 of the clamp.
- the post is manipulated into the correct position to allow for the desired amount overhang over the hole in the ground 40 to ensure a desired length of post enters the hole when erected.
- the second part of the clamp 7 is prepared for engagement with the first part 5 by first inserting the threaded end of the locking means into each opening 12.
- a nut 36 is attached to the threaded end 16 to loosely hold each of the two locking means 13 to the second part 7.
- the second part is then laid on top of the post and positioned directly above the first part so that the opposing pairs of outwardly extending tabs 9 and 11 are aligned with one another.
- a portion of the shaft 26 is then slid into each respective slot 10.
- the clamp 3 is then brought into gripping engagement with the post 25 by tightening one or both of the nuts 36.
- Recesses 18 may be formed adjacent the slots 10 for respectively receiving a pair of lugs and holding them in preferred alignment with respect to the outwardly extending tab so as to prevent the shaft 26 from turning when the nut 36 on either or both locking means are turned. This completes the preparatory work associated with attaching the brace and locking the clamp.
- Figure 13 best illustrates the brace assembly attached to the post on the stand ready for erection.
- the person To erect the post, the person lifts the end of the post in contact with the ground. This causes the post and brace assembly to pivot about the two feet that are already in contact with the ground. This allows the end of the post to swing into the hole in the ground. The person continues to lift the post into a substantially vertical orientation until the leg and foot assembly attached to the second part of the clamp makes contact with the ground on the opposite side of the hole. The user can then use a tool such as a spirit level to see how far off vertical the post is. Adjustment of the post's angle can be made by turning the adjustment means 22 and/or 32 on one or more legs.
