Abstract

A portable device for connecting to scaffolding and which provides rotary motion to a drive wheel, to move scaffolding in select directions. The device includes a power wheel, rotary driven through a perpendicular or right-angled gear reduction, receiving its rotary force from a drive shaft, and the drive shaft couples with a portable drill, or other tool, that furnishes the rotational force necessary for driving the drive shaft, and its associated drive wheel. The bracket mechanism supporting the portable appliance supports the appliance during its delivery of rotary force to the drive shaft, and its wheel, and likewise, pivotally mounts to an outer support sleeve or tube that furnishes steering, to the drive mechanism, and consequently to the scaffolding, during its power movement. A locking bar affixes a pair of the castors into alignment.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A scaffold incorporating a scaffold moving device including a scaffold frame of substantial height, said scaffold frame having a series of castors at various locations to facilitate the movement of the scaffold on a floor, a pair of said castors being at the front of the scaffold, and a pair of said castors being at the back of the scaffold, a motorized wheeled assembly operatively associated with the bottom of the scaffold to provide for motive force to the scaffold to achieve its movement, a wheeled assembly being operatively associated with at least a pair of the said scaffold castors, and a locking bar operatively associate with the other of said pair of scaffold castors to maintain said castors in alignment and to prevent their pivoting.  
     
     
         2 . The scaffold of  claim 1  and wherein said locking bar affixing with the pair of castors located opposite upon the scaffold from the motorized wheeled assembly as used for moving said scaffold.  
     
     
         3 . The scaffold of  claim 2  wherein said locking bar comprises a length of bar for extending the space between the pair of said castors, and said locking bar affixing, at each end, to the castor axle bearing to prevent pivoting of the associated castors during motorized movement of the scaffolding.  
     
     
         4 . The scaffolding of  claim 3  and including an adapter securing with the bearing axle of each of the pair of castors, and a retention sleeve connecting with each end of the rod means, and securing onto the locking adapters, to prevent pivoting of the castors when the locking bar is affixed into its operative position.  
     
     
         5 . The scaffolding of  claim 4  wherein each retention sleeve of the locking bar includes a lateral slot provided partially therein, each adapter having a flange integrally formed therewith, the flange of each adapter provided for inserting into the lateral slot of the retention sleeve, locking means maintaining the adapter within its associated retention sleeve, thereby affixing the locking bar to each of the bearings of the pair of aligned castors to prevent their pivot during scaffold movement.  
     
     
         6 . A locking bar for use in combination with a pair of castors to maintain their alignment and prevent their pivoting during usage, each castor having an axle bearing shaft, a locking bar provided for affixing onto the axle bearing shaft of each castor, and which when locked in place, preventing the pivot of the pastors during movement.  
     
     
         7 . The locking bar of  claim 6  wherein said locking bar includes a length of shaft, each end of the shaft having a retention sleeve provided thereon, each castor axle bearing shaft having an adapter securing therewith, said adapters cooperating with the retention sleeve of the locking bar shaft to prevent turning of the castors when the locking bar is affixed in place between said pair of castors.  
     
     
         8 . The locking bar of  claim 7  wherein each adapter includes an integral flange, each retention sleeve having a lateral slot provided therein, the flange of each adapter provided for sliding into the lateral slot of each adapter, and when locked in position, preventing the turning of the pair of aligned castors to prevent their pivoting during movement.  
     
     
         9 . The locking bar of  claim 8  and including a locking pin operatively associated with each of the retention sleeves, said locking pin capable of being extended into the path of the lateral slot of each said retention sleeve to prevent removal of the flanged adapter when the locking bar is secured between a pair of castors to prevent their turning during movement.  
     
     
         10 . The locking bar of  claim 9  wherein each adapter provided for securement of the bearing axle of its associated castor when the locking bar is secured during usage.
