摘要:
A first barrier section (1), a height-adjustable barrier (20) comprising the first barrier section (1), a kit of parts and a method for converting a first barrier section (1) to the height-adjustable barrier (20), is disclosed. The first barrier section (1) is prepared for the converting by being arranged to telescopically receive a second post (13) of a second barrier section (11) inside a respective tube-shaped first post (3) of the first barrier section (1), and a respective stop (7) is arranged to fit inside the respective first post (3), which stop (7) comprises a stop surface (7c) to be arranged at a distance from a lower end (4) of the respective first post (3). The stop (7) is arranged to prevent a further motion of the second post (13) of the second barrier section (11) inside the respective first post (3) in direction towards a lower end (4) of the first posts (3).
摘要:
A barrier section (1, 15) for a balcony, a platform or a restaurant area, comprises two side posts (3), which support a movable panel (4). The movable panel (4) has an upper and a lower position. Each side post (3) includes a fluid cylinder (9), for raising or lowering the movable panel (4). A barrier (23) may be constructed including at least one such barrier section (1, 15).
摘要:
A closure arrangement for an opening in a building includes a number of closure elements (2, 3). At least one of the closure elements (2, 3) is vertically movable by means of operating arms (18). The operating arms (18) are powered by a driving device, which includes at least one drive motor (10). On either side of the closure arrangement, the driving device includes an upright screw (12) which is mounted in an axial bearing (15). Each screw (12) has a nut (14), and the operating arms (18) have abutment faces (17) which rest on the nuts (14). Couplings (16) couple the abutment faces (17) and the nuts (14) with a play for permitting an angular discrepancy between each abutment face (17) and the longitudinal axis of the respective screw (12) as well as transversal movements thereof.
摘要:
The present invention relates to a hospital bed having a frame (1) with two articulated pairs of wheels (9), between which is arranged an articulated or non-articulated pair of wheels (2). The invention is characterized in that the intermediate pair of wheels (2) is spring-supported (4) at the frame (1) in order to facilitate transport of the bed from place to place.
