20080283712 | Seismic damper - A seismic damper includes upper and lower brackets, and a link mechanism. The upper bracket is formed with an upper hole. The lower bracket is formed with lower and intermediate holes. The link mechanism includes a support link, and first, second, and third pivot joints. The support link has first and second ends, each of which is formed with a through-hole, and an intermediate portion, which is formed with a through-hole. The first pivot joint extends through the upper hole in the upper bracket and the through-hole in the first end of the support link. The second pivot joint extends through the lower hole in the lower bracket and the through-hole in the second end of the support link. The third pivot joint extends through the intermediate hole in the lower bracket and the through-hole in the intermediate portion of the support link. | 11-20-2008 |
20090236487 | Platform Telescoping Mechanism - Disclosed are various embodiments of a platform telescoping system which comprises a platform, a first supporting arm, a second supporting arm, a telescopic driving mechanism which comprises a first power output, end and a rotational driving mechanism which comprises a second power output end. The first power output end is integrated with the second supporting arm and causes the second supporting arm to move in a first direction, and the second power output end is integrated with the platform and causes the platform to pivot between a first position and a second position. The second supporting arm telescopes with respect to the first supporting arm for adjusting the position of the platform. The space occupied by the platform telescoping system may be reduced while its functions enhanced. | 09-24-2009 |
20110253873 | Seat Base Sliding Apparatus - The present disclosure discloses a seat base sliding device applied to a seat of a heavy machinery such as a loader, an excavator, or the like. The seat base sliding device includes: a seat base with a lower part is fixed to a floor of a vehicle body and an upper part at which a seat is installed; a sliding plate slidable inwards and outwards in a lateral direction of the seat base at both left and right sides of the seat base and in which a control stand is fixed to one side thereof; and at least one adjustment unit selectively fixing the sliding plate of which the position is determined by sliding movement to the seat base. The present disclosure is capable of preventing a cabin from knocking against both control stands of a seat device at the time of assembling the cabin around the seat device and in addition, preventing the corresponding control stands from interfering in a thigh of a driver at the time of operating a control lever of each control stand laterally after assembling the cabin. | 10-20-2011 |
20140183322 | MOVABLE SUPPORT DEVICE - A support device for moving an item on a surface. A main body includes a panel and a sidewall. A handle assembly engages the main body and includes a first transportation mechanism. The support device includes a resistance portion on the main body for engaging a surface and resisting movement of the support device when in a resistive mode. The handle mechanism lowers the first transportation mechanism to engage the surface and disengage the resistance portion from the surface in a transportive mode to encourage movement of the support device and the item supported thereon. | 07-03-2014 |
20140291467 | CARRYING DEVICE - A carrying device comprises a sliding rail, a support stand and a plurality of rods. The sliding rail comprises a fixed rail and a withdraw rail. The withdraw rail is configured for moving back and forth relative to the fixed rail. The support stand has a top surface. The sleeve holes are disposed on the top surface. The sleeve holes have a sleeved axis, while opposite two ends of the support stand respectively have at least one installation hole having an installation axis. The sleeved axis and the installation axis do not intersect, and the withdraw rail is installed on the installation hole of the support stand. The rods each have a fixed end and a cantilever end opposite to each other. Each of the fixed ends is installed on each of the sleeve holes of the support stand. | 10-02-2014 |
