| 20110309226 | SAFETY ANCHOR DEVICE - A safety anchor device for limiting movement of a person or arresting a fall of a person working at height, and in particular to an inflatable safety anchor device that may be positioned at a high point and then inflated with a liquid to provide a dead-weight anchor device. A dead-weight anchor device for securing a line to a person working at height comprises an attachment for a line that is provided on a top surface of a flexible-walled container. The container has an internal volume that may in use be inflated with a quantity of water to provide an anchoring dead-weight and subsequently deflated by letting water escape. The container has a plurality of flexible walls, including a pair of walls that are internally connected by drop threads that limit the separation between said pair of walls when the internal volume is inflated by water. | 12-22-2011 |
| 20130037681 | Counterbalance For A System For Providing Cyclic Motion - In one embodiment, a system for providing cyclic motion includes a magnetic drive having an electrically conductive coil defining a bore and a magnetic member movable through the bore. A control provides current to the coil and selectively reverses the direction of the current to move the magnetic member through the bore. In another embodiment, the system includes a counterbalance. The counterbalance includes a biasing member for reacting against a load applied to a support, and a lever arm coupled to the biasing member for varying a preload of the biasing member. In another embodiment, the magnetic drive and the counterbalance may be incorporated into an apparatus for reciprocating a person. | 02-14-2013 |
| 20130043367 | Weight Balance Module and Gravity Center Adjustable Storage Device Using the Same - A weight balance module and a gravity center adjustable storage device using the same are provided. The weight balance module is disposed on a bottom face of a storage device and includes a balance plate and at least one balance piece. The balance plate has a plurality of predefined areas. The balance piece is selectively disposed on one of the plurality of the predefined areas. | 02-21-2013 |
| 20130153734 | Weight assembly for covers - A weight assembly that attaches to a cover; that, when used with a plurality of weight assemblies of the same type spread evenly around the edges of a cover will hold the cover in position. | 06-20-2013 |
| 20140151522 | AUTOMATIC BALANCING STRUCTURE OF MEDICAL BALANCING STAND - An automatic balancing structure of a medical balancing stand includes an elastic member arranged in each clearance C. In a normal state, a lever and a turn plate turn together through the elastic members, to follow a rotative movement of a lateral arm. When an imbalance occurs on the lateral arm, the lateral arm produces torque with which a contact part of the lever presses and deforms one of the elastic members to activate a corresponding one of switches S | 06-05-2014 |
| 20150360585 | COUNTERWEIGHT FOR TENSIONING THE WIRE OF A CATENARY IN ARAILWAY LINE - A counterweight is provided for tensioning the wire of a catenary in a railway line, comprising a metal shell ( | 12-17-2015 |
