An inline tool holder including a shaft collar, a mounting plate, a first enclosure, and a second enclosure. The mounting plate is concentrically arranged around the shaft collar and includes a first surface, a second surface, and an attachment mechanism. The first enclosure is removably coupled to the first surface of the mounting plate and the second enclosure is removably coupled to the second surface of the mounting plate. The attachment mechanism of the mounting plate extends radially beyond an outer edge of both the first enclosure and the second enclosure.

The present invention relates to a support arrangement for supporting a load at an elevated position, particularly where the load can then be used for its intended purpose at an elevated position and where the weight of the load is supported. The support arrangement comprises a support structure and a weight balancing device supported by the support structure for balancing the weight of a load, the weight balancing device having a first line extending therefrom and having a distal end for engaging with a load, where the first line is extendable and retractable from the weight balancing device to enable balancing of the weight of the load at a desired elevation. The support arrangement further comprises a retractor device comprising a carrier receiving a second line where the second line is retractable and extendable from the carrier, the second line having a distal end secured to the first line at a securing location such that as the first line is extended the second line retracts onto the carrier, and conversely as the first line is retracted the second line deploys from the carrier, the retractor device further comprising a restrictor for restricting the speed of deployment of the second line from the carrier.

A balancer for tools includes a rotary drum for winding and unwinding a cable, which is adapted with a free end thereof to support a tool. The balancer also includes a spring, wound around the main rotation axis of the drum, which is adapted to develop an elastic reaction contrasting the unwinding of the cable.

A tool guide has a mounting, a lifting mechanism, and a chassis. The mounting is for fixing a hand-held machine tool. The mounting is mounted on the lifting mechanism. The lifting mechanism has a propulsion unit for vertically lifting the mounting. The chassis has two wheels on a wheel axle, a drive coupled with the wheels, and a steering system. The lifting mechanism is rigidly mounted on the chassis. A center of gravity sensor is arranged to detect a lateral deflection of the center of gravity of the lifting mechanism relative to the wheel axle. The steering system is configured to control the drive to deliver a torque counteracting the lateral deflection.

A cart comprising a support frame having a plurality of wheels, a reel supported by the support frame, and a tool tethered to the support frame.

A self-aligning tool guide has a holder for securing a portable power tool for working on a ceiling, a lifting mechanism, and a self-balancing chassis. The holder is mounted on the lifting mechanism. The lifting mechanism has a propulsion system for raising the holder parallel to a lifting axis. The self-balancing chassis has two wheels on a wheel axis and a drive coupled to the two wheels. A sensor serves for detecting a contact pressure of the holder, the contact pressure acting in the direction of gravitational force. The control station activates the propulsion system depending on the detected contact pressure.

The invention discloses a force adjustable universal displacement tensioner, including a suction cup assembly 1 and a housing 2; outer gear spring cover 3, coil spring covers and a rope puller 4 are arranged in the housing 2 coaxially through a coil spring shaft; coil springs are disposed in both the outer gear spring cover 3 and the coil spring cover; a pulling rope is disposed on the rope puller 4; one end of the pulling rope which extends out of the housing 2 is connected to a handle 5.

A guide assembly for supporting a tool employs an arcuate guide configured to have a tether coupled thereto. The arcuate guide is configured to apply a reaction force to the tether to oppose gravitational force applied to the tool. The assembly further includes a mount assembly is configured to couple the arcuate guide to the tool. At least one support bar is coupled to the arcuate guide and the mount assembly. The arcuate guide, the mount assembly, and the at least one support bar are configured to maintain the reaction force in alignment with a center of gravity of the tool as the tool is rotated with respect to the center of gravity.
