| 20090101039 | Electric motor driven traversing balancer hoist - A balancer hoist has an electric servomotor driving irreversible gearing in turn driving a hoist chain drive. A float mode and a manual mode are provided using two independent load sensors for sensing the load weight and force applied to a control grip. A traversing control is produced by a tractor carriage rolling on an overhead rail connected to a trolley also traveling on the rail and supported on upper hoist assembly. A load sensor interconnects the tractor carriage and upon hoist assembly to sense forces created by an operator pulling on the chain, which are used to control an electric motor on the tractor carriage driving a pinion gear engaged with a gear rack on the overhead rail to positively drive the carriage, trolley and upper hoist assembly along the rail. A stationary dual hoist system is also described in which two hoist assemblies are interconnected by a chain and sprockets to provide synchronized operation. | 04-23-2009 |

| 20130269565 | PATIENT POSITIONING SYSTEM AND RAIL FOR USE THEREIN - A patient positioning system and a rail for use in the system. According to one embodiment, the system includes first and second stationary rails arranged parallel to one another. First and second sets of mounting assemblies are used to fix the first and second stationary rails, respectively, to a ceiling. A traverse rail is slidably coupled to the stationary rails. The system also includes a harness for holding a patient and a motorized assembly for raising and lowering the harness, the harness being slidably coupled to the traverse rail. At least one of the first stationary rail, the second stationary rail, and the traverse rail is shaped to include a top wall, a bottom wall, a left wall, a right wall, a substantially open front, a substantially open rear, a first rib extending from the left side wall to the right side wall, and a second rib extending from the top wall to the first rib, the first rib and the second rib jointly dividing the interior of the rail into a pair of upper chambers and a lower chamber. | 10-17-2013 |

| 20140069291 | Transmission system of LCD panel and automatic crane thereof - The present invention discloses a transmission system of an LCD panel and an automatic crane thereof. The transmission system comprises a guide rail and a transmission apparatus. The transmission apparatus comprises a main body, an alarm unit, a main wheel disposed at the bottom of the main body, and a sensor disposed below the main body. The main wheel abuts to the guide rail so that the transmission apparatus can move along a preset direction of the guide rail. The sensor is for detecting whether the main wheel is abnormal The alarm unit is for generating an alarm when the sensor detects that the main wheel is abnormal. The present can achieve the real-time monitoring for the operation of the main wheel by disposing the sensor in order to timely detect the abnormality and generate an alarm when it is abnormal through the alarm unit. | 03-13-2014 |

| 20110303114 | SLIDE RAIL AND IMAGE FORMING APPARATUS WITH THE SAME - A slide rail includes an outer rail and an inner rail. The inner rail includes a top face portion, main-portion side walls, outer deck portions, and end-portion side walls. The outer rail includes a bottom wall and a storage portion. The main-portion side walls and the end-portion side walls are both provided adjacently on both sides of the top face portion in a width direction thereof, and bent toward outer rail. The main-portion side walls are provided in a portion other than one end portion in the longitudinal direction. The end-portion side walls are provided in the one end portion. Each outer deck portion extends outward in the width direction to be continuous to an edge of each main-portion side wall opposite the top face portion. The storage portions are provided adjacently on both sides of the bottom wall in the width direction and bent toward the inner rail to cover the outer edge portions. | 12-15-2011 |
| 20150135982 | TRACK ASSEMBLIES AND TRACK ASSEMBLY KITS FOR CHILDREN'S RIDE-ON VEHICLES - Track assemblies and track assembly kits for children's ride-on vehicles, as well as children's ride-on vehicle systems, according to the present disclosure are configured for assembly and disassembly of a track assembly. Track assemblies may include elongate rail members, couplers that are configured to couple together two elongate rail members, and optionally tie members that include one or more couplers. Generally, track assemblies comprise a left rail (including longitudinally aligned elongate rail members) and a right rail (including longitudinally aligned elongate rail members) in a spaced-apart and parallel relationship. Elongate rail members, couplers, and/or tie members are configured to releasably and repeatedly couple together. In the disassembled state, the component parts may be stored and/or shipped compactly. In the assembled state, the track assembly may define a track path, and the track assembly may be configured to guide the children's ride-on vehicle along the track path. | 05-21-2015 |
| 20160031648 | CONVEYING DEVICE AND CARRIAGE FOR CONVEYING DEVICE - The invention relates to a conveying device comprising at least one movable carriage on which at least one first group and at least one second group of track rollers are disposed, and a track rail disposed so as to be locationally fixed for guiding the carriage. The track rail has at least one track face, at least one straight portion and at least one curved portion. The track rollers are configured in such a manner that during movement of the carriage along the straight portion, exclusively the track rollers of the first group roll on the track face assigned to the straight portion, and during movement of the carriage along the curved portion, exclusively the track rollers of the second group roll on the track face assigned to the curved portion. The invention furthermore relates to a further conveying device and corresponding carriages, as described herein. | 02-04-2016 |
