A ladder stabilization support assembly designed to provide lateral and vertical stabilization support to ladders in general and long span extension ladders in particular such as multi-sectional extension ladders that lean against stable vertical support structures when in use and span from six feet when fully retracted all the way up to forty feet when fully extended, the ladder stabilization support assembly comprising:
- two identical telescopic support legs pivotally mounted on opposite sides of a ladder, wherein each telescopic support leg is built to telescopically extend or retract by taking an advantage of a light-weight t-slotted aluminum profile and to provide an ability to effectively support and level the ladder on any uneven supporting grounds, and each telescopic support leg further comprising:
- a square tube profile member;
- a t-slot profile member made of a conventional t-slotted aluminum profile having t-tracks configured to accept conventional t-slot fasteners, wherein said t-slot profile member is fitted to telescopically slide inside the square tube profile member;
- an upper end plug inserted into an upper end of the square tube profile member provides for an attachment supporting base for a pivot joint;
- the pivot joint provides for a pivotal movement of the telescopic support leg when it is swung in or out in lateral direction with unlimited number of pivotal adjustment positions and provides for a swivel movement of the telescopic support leg when it is moved forward or backwards with unlimited number of swivel adjustment positions within a recommended range;
- an upper mounting bracket to mount or dismount an upper end of the telescopic support leg on or off a ladder side rail and to securely clamp the upper end of the telescopic support leg to the ladder side rail;
- a lower mounting bracket to mount or dismount a lower end of the telescopic support leg on or off the ladder side rail and to securely clamp the lower end of the telescopic support leg to the ladder side rail in a folded position parallel to the ladder side rail;
- a swivel leveling foot to provide for an effective friction resistant supporting base which automatically adjusts to any uneven ground contour;
- and
- an adjustable sliding mechanism provides for numerous length adjustment positions and adjusts automatically when the t-slot profile member is released to slide down under its own weight to engage with the supporting ground, wherein the adjustable sliding mechanism further comprising:
- a molded plastic hollow plug inserted into a lower end of the square tube profile member and a molded plastic bushing wrapped around an upper end of the t-slot profile member, both made of a smooth and dense plastic material, to provide for a smooth, low tolerance, snug and wobble-free telescopic sliding action;
- convenient and user-friendly wing knob fasteners protruded through connecting apertures in the lower end of the square tube profile member and in the molded plastic hollow plug, and threaded into self-locking t-nuts placed inside the t-tracks of the t-slot profile member to control the telescopic sliding action by locking the t-tracks against the square tube profile member in specific length adjustment positions or releasing the t-tracks to resume continues sliding, wherein said self-locking t-nuts are configured to self-align within the t-tacks resulting in a smooth and unobstructed sliding of the t-tracks alongside of said self-locking t-nuts;
- self-locking t-nuts positioned inside the t-tracks at the upper end of the t-slot profile member below the molded plastic bushing and locked in place by suitable socket set fasteners to terminate the sliding action when the telescopic support leg is fully extended preventing the t-slot profile member from completely sliding out of the square tube profile member;
- and
- self-locking t-nuts positioned inside the t-tracks at a lower end of the t-slot profile member and locked in place by suitable socket set fasteners to terminate the sliding action when the telescopic support leg is fully retracted,
- such that when said self-locking t-nuts are unlocked they can be slidably moved along the t-tracks of the t-slot profile member and be re-locked in any desired position to adjust a range of sliding by either increasing or decreasing the maximum length by which the t-slot profile member can retract or extend.
