摘要： A stair lift includes a track, a carriage, a drive mechanism and a folding mechanism. The track has a main track section and a lower track section. The lower track section is pivotally mounted to the main track section and is moveable between a lowered position and a raised position. The folding mechanism shifts the lower track section to its lowered position whenever the carriage and seat approach the lowermost stairs and lifts the lower track section to its raised position as the carriage and seat move up the stairway. The folding mechanism is actuated and powered by movement of the carriage and does not require its own motor, cylinder, or other actuator.

摘要翻译： 楼梯升降机包括轨道，托架，驱动机构和折叠机构。 轨道具有主轨道部分和下部轨道部分。 下轨道部分可枢转地安装到主轨道部分并且可以在降低位置和升高位置之间移动。 每当托架和座椅接近最低楼梯时，折叠机构将下轨道部分移动到其下降位置，并且当托架和座椅向上移动楼梯时将下轨道部分提升到其升高位置。 折叠机构通过滑架的移动而被致动和驱动，并且不需要其自身的电机，气缸或其它致动器。

摘要： A stainless steel guard plate for preventing forced entry into certain automobilies by forcing a screwdriver between the door handle mechanism and the outer door panel to unlock the door is retrofitted to the automobile. The handle mechanism is removed from an opening in the door. The guard plate includes a stainless steel plate having an aperture through which an operative portion of the handle mechanism extends, with side flanges of the guard plate extending inwardly along the upper and lower edges of the guard plate aperture and through the original opening in the door panel. A first screw which is accessible through a rear end plate of the door when it is opened, passes through a hole in an inwardly extending tab of the guard plate and into a threaded hole in a tongue member of the handle mechanism. The first screw is tightened, drawing the rear portion of the handle mechanism tightly against the guard plate, pressing it tightly against the outer surface of the door panel. A second screw extending through the forward part of the handle is used to tighten the front end of the handle against the door panel.

摘要： An improved automobile anti-theft guard plate that provides exceptional strength through the use of two bonded plates. The first plate has a flanged circumference to enclose the second plate. These flanges, especially when combined with the second plate's inherit strength, provide for enhanced rigidity to withstand deformation from a pry bar. An opening through both plates permits the automobile's handle lock activation and door opening mechanism access to these mechanisms within the automobile door. A tower or vertical member on the guard plate extends vertically from the plates and at least partially surrounds and shields the handle's mechanisms to even further dissuade tampering by a thief. The guard plate is additionally designed to permit the handle to be secured thereto through the use of tabs which engage the handle at the same time the handle is engaging the opening mechanism. This simultaneous engagement is accomplished through a sliding action of the handle relative to the guard plate and the automobile door.

摘要翻译： 一种改进的汽车防盗保护板，通过使用两个粘合板提供卓越的强度。 第一板具有带凸缘的圆周以封闭第二板。 这些凸缘，特别是当与第二板的继承强度相结合时，提供增强的刚度以承受来自撬杆的变形。 通过两个板的开口允许汽车的手柄锁启动和门打开机构进入汽车门内的这些机构。 防护板上的塔架或垂直部件从板上垂直延伸，并至少部分地围绕和屏蔽手柄的机构以进一步阻止小偷的篡改。 防护板另外设计成允许手柄通过使用与手柄接合开口机构的同时接合手柄的凸片来固定到手柄上。 这种同时接合通过手柄相对于防护板和汽车门的滑动动作来实现。

摘要： An improved automobile handle guard plate assembly which provides added strength via a lipped brace which overlays and strengthens a security plate. The security plate and the brace are secured together with an adhesive and positioned between the exterior door handle and the automobile's door. The door handle is permitted easy access to the locking mechanism within the door via an opening in the security plate. A thief trying to enter the automobile by accessing the locking mechanism through the door, finds a security plate to prevent access and a brace on the security plate to preventing deformation of the security plate.
