摘要： A column assembly including two telescopically engaged, coaxial column members whose relative axial movement is releasably prevented by an arresting mechanism in one of the column members. An opening transverse to the axis gives access to the releasing member of the arresting mechanism in the interior of the one column member. A unitary bracket passes through the opening and is fastened to the one column member in the interior thereof. A lever having respective arm portions in the column interior and outside also passes through the opening and is secured to the bracket by apivot for movement in a plane passing through the releasing member so that the arm portion in the interior of the column may engage and operate the releasing member when the outer arm portion is moved manually.

摘要： A hydraulically lockable lifting device particularly adapted for height adjustment of tables comprising a gas spring in which a piston mounted in a piston rod and acting against compressed gas travels in a tube which is sealed with respect to the outside, wherein both sides of the piston are connected by an openable passage that connects chambers filled with an incompressible medium and a pump for pumping the incompressible medium from one chamber into the other.

摘要： A power unit for a stool and the like. The stool may comprise a seat mounted upon a vertical post comprising the power unit, having upper and lower parts, the post being secured to a base. The power unit has a ram which telescopes within a cylinder. The power unit further comprises a reservoir containing oil under pressure of compressed air which can be used to change the effective length of the power unit. A flow control valve and a lever controls the flow of the oil between the reservoir and the cylinder so as to regulate the mentioned effective length. The reservoir and the valve are disposed at one end of the power unit. An improved seal having a center portion and flared inner and outer lips is used to seal parts of the power unit so as to prevent leakage of air or oil.

摘要： 1123030 Seats REINHARD HORNLEIN K G 12 Nov 1965 [14 Nov 1964 23 Dec 1964 28 Jan 1965 23 Mar 1965 24 Mar 1965] 48147/65 Index F2S 31 [Also in Division B8] A lifting unit, Fig.1, for adjusting the vertical height of a table for chair comprises a cylinder 1 with chambers 2, 3, 4. Chamber 2 contains gas under pressure and is bounded by a floating piston 7. Chambers 3 and 4 contain oil and are separated by a fixed wall 9. A guide 10 with a rod 11 is slidingly arranged in chamber 4. Connection between the chambers 3, 4 is through ports 12, 13 controlled by a slide valve 15 operated manually by a bar 21. In the position shown the chamber 3 is isolated from chamber 4 so that the unit is locked hydraulically. When the valve 15 is moved down so as to connect ports 12, 13 the gas in chamber 2 expands forcing the piston 7 down and transferring oil from chamber 3 to chamber 4, oil also passing from above the guide 10 to below it through a port 22, which may be a throttle port. So that chamber 4 can accommodate the additional oil the rod 11 is forced downwards. The guide 10 may have one or more one-way valves which permit rapid passage of oil during lowering. The chambers 2 and 3 may be separated by a solid or hollow ball 27, Fig.2 (not shown) of resilient material. As shown in Fig. 7 the chambers 2 and 3 may surround the chamber 4 as an outer cylinder. The chambers 2 and 3 may be larger in diameter than the chamber 4, Fig. 8 (not shown). Other types of valve may replace the slide valve 15 to control passage of oil from chamber 3 to chamber 4.
