摘要： Pneumatic pop-up unit for material handling equipment. In one embodiment, the unit comprises a stamped metal housing having a circumferential flange extending radially outwardly from the top. The unit also comprises a stamped metal cap comprising an outer side wall bent down across the outside edge of the flange and then radially inwardly against the bottom surface of the flange. The unit further comprises a two-piece stamped metal piston slidably mounted within the housing. The unit further comprises a stamped metal race disposed within the piston. A monolayer of ball bearings are arranged within the race. A primary ball is seated directly on top of the bearings. The top of the primary ball extends partially through the open top of the top piston piece. The unit further comprises a rubber seal fitted around the piston and a coiled spring for biasing the piston downwardly within the housing.

摘要： A ball-type anti-friction device which has a housing, a ball cage mounted within the housing for movement relative to the housing between a lower inactive position and an upper active position. The ball cage contains a relatively large ball mounted on relatively small bearing balls so that when the ball cage is in the lower or inactive position, the large ball is below the top surface of the housing and when the ball cage is in the upper or active position, the ball extends above the top surface of the housing. In a first embodiment, the housing contains a double acting fluid drive system. The fluid drive system includes two fluid chambers and a piston connected to the ball cage. The piston is selectively actuated by selective pressurization of the two fluid chambers. In a second embodiment, the ball cage is actuated by a single acting fluid drive system. A piston is connected to the ball cage and is biased downwardly to normally maintain the ball cage and large ball in the lower or inactive position. The housing contain a single fluid chamber which, when pressurized, causes the ball cage and large ball to move to the active or upper position in opposition to the biasing means.

摘要翻译： 一种球型抗摩擦装置，其具有壳体，球保持架安装在壳体内，用于相对于壳体在下部非活动位置和上活动位置之间移动。 球保持架包含安装在相对小的轴承球上的相对较大的球，使得当球保持架处于较低或不活动位置时，大球在壳体的顶部表面下方，并且当球笼处于上部或主动 位置，球延伸到壳体的顶表面之上。 在第一实施例中，壳体包含双作用流体驱动系统。 流体驱动系统包括两个流体室和连接到球笼的活塞。 通过两个流体室的选择性加压来选择性地致动活塞。 在第二实施例中，球保持架由单作用流体驱动系统致动。 活塞连接到球笼，并向下偏压，以将球保持架和大球保持在较低或非活动位置。 壳体包含单个流体室，其在加压时使球保持架和大球相对于偏置装置移动到主动位置或上部位置。

摘要： Featured is a unidirectional rotating support assembly that is located in one or more apertures provided in a surface of a work station, a scissors lift, a cart conveyor or any other work station, bench, table, platform or device known in the art involving the transportation of articles. Typically the work surface includes a plurality or more of such apertures. The unidirectional rotating support assembly of the present invention generally includes a unidirectional rotating member, a support member and a rotating member support mechanism that rotatably supports the unidirectional rotating member with respect to the support member. The support member is configured or arranged so a portion thereof is received in the aperture in such a fashion that the support member has limited, if any, ability to move with respect to the work station surface (e.g., axis of rotation for the rotating member has limited motion transverse to and/or along the axis or rotation). Thus, the rotating member also is maintained in a relatively fixed position with respect to the work surface. The support member includes an aperture therein, whose long axis is generally perpendicular to the work surface. The rotating member support mechanism is arranged so a portion thereof extends across this aperture or opening in the support member such that the unidirectional rotating member is disposed therein. The supporting mechanism in a particular embodiment is an axle and the unidirectional rotating member can be one of a wheel or a roller.
