摘要： A column unit, in particular a chair column unit, including a base tube (310) and a pneumatic spring (318), further comprises an axially movable guide bushing (314) which is inserted in an axially movable manner in the upper end (310b) of the base tube (310), and which encloses an axially movable part (318b) of the pneumatic spring (318). An exit movement of the guide bushing (314) can be effected, e.g., by driver- or pusher-stops (326, 314g). The exit movement is restricted by pullout-restricting stops (316, 312g) which are releasable for the disassembly of the column unit.

摘要： According to an illustrative example of the invention, a gas spring is combined with a telescopic tube which is axially slidable on the cylinder of the gas spring. The piston rod and the telescopic tube are provided at the respective most remote ends thereof with fastening eyes. The telescopic tube can be fixed in a plurality of positions with respect to the cylinder. For such fixation, the cylinder is connected with a carrier within the telescopic tube between opposite end walls of the cylinder and the telescopic tube. A locking bolt is guided within the carrier in a direction transverse to the axis of the telescopic tube. The locking bolt is engageable with a corresponding plurality of openings in the telescopic tube. The locking bolt is biased by a spring into an engagement position with respect to a respective opening and can be released from such engagement by being inwardly pressed by an operator.

摘要： According to an illustrative example of the invention, a gas spring comprises a cylinder which is closed at both ends thereof. A piston is provided within the cylinder and separates two working chambers within the cylinder. The working chambers are filled with a pressurized gas. The piston is connected with a piston rod which extends axially through one end of the cylinder. The working chambers can be selectively connected or separated from each other through an axial channel extending through the piston. This axial channel accommodates a valve pin. The valve pin is axially movable by an actuating rod accommodated by an axial bore of the piston rod. The piston is in sealing engagement with an inner circumferential face of the cylinder. The valve pin is in sealing engagement with the channel. The piston is provided with an elastic covering layer, which covering layer provides both the sealing engagement of the piston with the cylinder and the sealing engagement of the valve pin with the piston.

摘要： According to an illustrative example of the invention, a gas spring comprises a cylinder and a piston rod. The piston rod is axially movable with respect to the cylinder and has a fastening eye mounted on the outer end of the piston rod. A tubular protection member surrounds an end portion of the cylinder adjacent to the end of the cylinder which is passed by the piston rod. The other end of the protection tube surrounds a holding disk fixed to the piston rod adjacent to the fastening eye. The protection tube and the piston rod define an air space therebetween. The air space is substantially tight against a liquid treating agent, such as a lacquer. On the other hand, the air space is in air flow connection with the surrounding atmosphere so that in response to axial movement of the piston rod with respect to the cylinder, excesssive pressure within the air space is prevented.

摘要： A gas spring is provided in an illustrational example between a framework and a trunk cover of a motor vehicle for compensating for the weight of the trunk cover during movement of said trunk cover. The gas spring is hinged to the framework and to the trunk cover. For eliminating the spring force action on the hinge between the trunk cover and the gas spring in the closed position of the trunk cover, the part of the gas spring hinged to the trunk cover is supported on the framework, when the trunk cover is in its closed position. Alternately, the gas spring is locked when the trunk cover is in its closed position.

摘要： A positioning device is e.g. used for positioning the door of a motor vehicle in an opened position. The positioning device comprises e.g. a cylinder and a piston rod which extends inward and outwards of the cylinder through one end thereof. A flank face is provided at the inner wall surface of the cylinder. The piston rod carries a piston. The piston is provided with a counter-arresting ring which engages the flank face in a predetermined position. When the piston passes across the arresting flank of the cylinder, the counter-arresting ring is moved radially inwards with respect to the axis of the piston rod against elastic resistence. So, an increased resistance occurs against the axial movement of the piston rod with respect to the cylinder. This increased resistance against axial movement positions the door with respect to the body frame of a motor vehicle in a predetermined opened position and avoids that the door is closed unintentionally. Af the flank face and the arresting ring are enclosed within the cavity of the cylinder, they are not subject to environmental conditions, which might deteriorate their positioning function after a period of use. Lubricating agent may be provided within the cavity for lubricating the flank face and the arresting ring. As such lubricating agent is enclosed within the cavity of the cylinder, there is no risk for the vehicle driver to be polluted by the lubricating agent.
摘要翻译：定位装置是例如用于将机动车辆的门定位在打开位置。定位装置包括：气缸和活塞杆，其通过其一端向内和向外延伸。在气缸的内壁表面设有一个侧面。活塞杆带有活塞。活塞设置有止动环，该止动环在预定位置接合该侧面。当活塞穿过气缸的止动侧面时，防止止动环相对于活塞杆的轴线径向向内移动以抵抗弹性阻力。因此，抵抗活塞杆相对于气缸的轴向运动发生增加的阻力。这种增加的抵抗轴向运动的阻力将门相对于机动车辆的车身框架定位在预定的打开位置，并且避免了门被无意地关闭。在侧面和止动环之间封闭在气缸的空腔内，它们不受环境条件的影响，在使用一段时间后可能会使其定位功能恶化。可以在空腔内设置润滑剂以润滑侧面和止动环。由于这种润滑剂被封装在气缸的空腔内，所以车辆驾驶员不会被润滑剂污染的风险。

摘要： According to an illustrative example of the invention, a chair column comprises a base tube with a support plate. A gas spring is accommodated within the base tube. The piston rod of the gas spring is supported on the base tube by a ball bearing. The cylinder of the gas spring is guided at the upper end of the base tube by a guiding sleeve. The guiding sleeve is telescopical with respect to the base tube in response to outward and inward movement of the cylinder with respect to the base tube such that a full satisfactory guiding function is maintained between the cylinder and the base tube, even when the cylinder is in its uppermost position.

摘要： According to an illustrative example of the invention a gas spring has adjacent one end thereof an axially extending control pin. This control pin is prestressed towards an outer position and can be pushed inwards for opening a valve, which valve is provided in the passage between two working chambers established by a piston, said piston being fixed to a piston rod. When the pin is in its outward position, the gas spring is locked in the respective axial length. When the control pin is moved inwards, the axial length of the gas spring can be varied. The gas spring is intended for combination with a chair or table column. In combining the gas spring with a chair, the upper end of the gas spring cylinder is fixed to the lower side of the seat plate. The lower side of the seat plate is provided with a manipulating level. The manipulating lever engages the outer end of the control pin through a telescopic arrangement of control members or adapter elements. These control members can be adjusted with respect to each other in axial direction by axial movement without relative rotation during the axial movement. After the correct length of the telescopic arrangement has been adjusted, the telescopic members are fixed with respect to each other.

摘要： For a temperature-compensated gas spring, which consists of a container in which a concentrically arranged cylinder is arranged, where a main pressure chamber is separated in sealing manner from an auxiliary pressure chamber by a piston which is connected with a piston rod, a damping arrangement is provided for controlling the outward thrust speed. This is effected in that a damping chamber is arranged in which a damping piston provided with damping valves slides, the damping piston being arranged on an auxiliary piston rod which is in axially fixed connection with the piston rod.
