摘要： The present invention relates to a particularly compact and safe extendable access device for gaining access to elevated locations via a hatch opening. The access device comprises a telescopic ladder with a plurality of sliding elements movable between an extended position and a retracted position, each sliding element comprising two stiles connected by a rung. The stiles of each sliding element are interlocked with the stiles of adjacent sliding elements, wherein each sliding element comprises a first locking mechanism for releasably connecting at least one of the stiles to an adjacent stile of an adjacent sliding element, the first locking mechanism being adapted to lock each sliding element in its retracted position. The first locking mechanism of each sliding element is adapted to releasably connect at least one stile of each sliding element to a stile of an adjacent sliding element, which is closer to a top end of the telescopic ladder, and is adapted to automatically disconnect said stiles once an adjacent sliding element, which is closer to a bottom end of the telescopic ladder, is in its extended position. The first locking mechanism is adapted to automatically connect the at least one stile of said sliding element to a stile of the adjacent sliding element, which is closer to a top end of the telescopic ladder, when the adjacent sliding element, which is closer to the bottom end of the telescopic ladder, is moved from its extended position towards its retracted position.

摘要： A stair system (20; 300) comprises: a first length-adjustable stringer (40A; 308A); a second length-adjustable stringer (40B; 308B); and a plurality of tread assemblies (148; 350) installable to the first and second stringers. The system further includes at least one handrail (268; 302A, 302B). A plurality of balusters (280A, 280B; 360, 362) are attached or attachable to the tread assemblies and handrail. The tread assemblies each have an adjustable tread pitch.

摘要： A telescopic loft ladder is disclosed two stiles (16) each comprising sections (16a, 16b, 16c...) that are telescopically collapsible within each other, rungs (12,14) having two lateral ends each connected to a section of a respective one of the stiles (16), retractable pins (30) in the ends of the rungs (12,14) for engaging in holes in the sections (16a, 16b, 16c...) of the stiles to retain the stile sections in an extended position, and levers (34) on the rungs (12,14) that are automatically operated when two rungs (12,14) contact one another to disengage the pins (30) of the upper of the two contacting rungs (12,14) from the holes in the stiles to permit the collapse of the next higher rung. The uppermost section (16a) of each stile is rotatable relative to the section (16b) connected to the uppermost rung (12) of the ladder and has pin receiving holes (16d, 16e, 16f) that are circumferentially and axially offset from one another. At least one resilient element (50) is provided for biasing the next to uppermost rung (14) away from the uppermost rung (12) to ensure that the locking pin of the uppermost rung (12) engages within a hole in the uppermost stile section (16a) as the ladder (10) is being lowered.

摘要： A staircase having adjustable treads comprises two strings (11) which are rigidly connected to each other and between which a number of treads (16-19) are provided. Each tread is at its ends pivotally mounted on a bearing shaft (25-28) in the adjacent string and is connected to a link arm (29-32), the link arm being connected to an adjustable link means (33). The link means can be adjusted by means of an operating arm (20) in such a way that the treads are turned around their bearing shafts, maintaining the upper surfaces of the treads in parallel, so that the angle between the upper surfaces of the treads and the longitudinal direction of the strings is changed. The treads (16-19) can also be turned to a common plane, so that the treads form a substantially continuous, plain surface. By adjustment of the treads, the treads can be positioned substantially horizontally irrespective of the inclination of the strings to the ground plane, so that the staircase is comfortable to use. Alternatively, the treads can form a plain surface, so that the straircase can be used as a ramp, e.g. for transport vehicles or wheeled chairs.
