    • An object carrier utilizing a pair of canted wheels, both wheels being always engaged with the underlying track to provide a low friction smooth riding non jammable carrier. In one embodiment the wheels are continuously engaged with and drive one another. In another embodiment each wheel is engaged with a separate rolling bearing carried by the carrier wheels axles support block. The canted wheels arrangement causes the carrier to move in a straight line along the direction of pull without crab walking. The carrier (27) includes a carrier block (78) from which divergingly upwardly extend in a common plane a pair of axles (79) which are orthogonal to each other and oriented forty-five degrees to the horizontal and vertical directions. Wheels (81) mounted on the axles (79) engage one another at their upper ends so that as one wheel rotates in a given direction its frictional engagement with the other wheel drives the other wheel in the same direction which prevents twisting or cocking of the carrier (27) within the track. Depending from the carrier block (78) is a stem (83) which carries at its lower end a support chain (85). In a modified carrier, the upper bearing for the carrier wheels (81) is provided by a ballbearing (88) seated in a socket formed in the carrier block (78) proximate to its upper edge. The ball bearings (88) engage the inside surfaces of the wheels (81) and ride within a circular groove (89) formed on the wheels inside surfaces.
    • 使用一对倾斜轮的物体载体,两个轮总是与下面的轨道接合,以提供低摩擦平滑骑行的不可理解的载体。 在一个实施例中,轮子连续地接合并彼此驱动。 在另一个实施例中,每个轮与由承载轮轴支撑块承载的单独的滚动轴承接合。 倾斜的轮子布置使得载体沿拉伸方向在直线上移动而不需要爬行。 载体(27)包括一个承载块(78),在该公共平面上向上分散地向上延伸一对彼此正交并相对于水平和垂直方向定向成四十五度的一对轴(79)。 安装在轴(79)上的轮(81)在其上端彼此接合,使得当一个轮沿给定方向旋转时,与另一个轮的摩擦接合沿相同的方向驱动另一个车轮,防止扭转或翘起 载体(27)内。 取决于承载块(78)是杆(83),其在其下端承载支撑链(85)。 在改进的载体中,用于承载轮(81)的上轴承由靠近其上边缘而位于承载块(78)中形成的插座中的球轴承(88)提供。 滚珠轴承(88)与轮(81)的内表面接合,并且骑在形成在车轮内表面上的圆形凹槽(89)内。

    • A hospital curtain track system utilizing a track switch (25) which permits the use of a single privacy curtain (28) selectively for one of two or more adjacent bed cubicles. One track switch unit (25) between each two bed environment splices directly with the cubicle track (23, 24, 26) and eliminates extra connecting parts including the elimination of one complete track leg, resulting in minimal installation time and expense. The switch utilizes a pull-chains actuated toggle for shifting a horizontally shiftable switch section (37) for aligning a common track (26) with the desired curtain track.
    • 一种使用轨道开关(25)的医院窗帘轨道系统,其允许选择性地使用单个隐私帘(28)用于两个或更多个相邻床间中的一个。 每个两个床环境之间的一个轨道开关单元(25)直接与隔间轨道(23,24,26)接合,并且消除了额外的连接部分,包括消除一个完整的履带支腿,导致最少的安装时间和费用。 该开关采用拉链致动的拨动开关,用于移动水平可移动的开关部分(37),用于使公共轨道(26)与期望的帘式轨道对准。
