摘要： A stabilizing leg for attachment to a ladder for use on uneven surfaces comprises a rigid leg member (3) having a central longitudinal slot (6) through which extend U-bolts (17) for clamping the leg member (3) to the rungs (15) of the ladder. The U-bolts can be slackened to permit the leg member (3) to slide vertically relative to the rungs between stored and extended positions, and also to slide along the rungs between the opposed stiles. The leg can be used on a ladder without specific adaptation of the ladder. There is also disclosed a hooking support (30) for attachment to the stiles at the uppper end of the ladder for supporting the ladder from a ledge or spouting. The support comprises a number of adjacent hooking portions (34a) to (34d) spaced by a fraction of the ladder rung spacing.

摘要： The invention concerns a ladder with strings (1, 2), of which at least one string (1) can be varied in length by an extension device (6) in order to adapt the ladder to sloping support surfaces. The ladder further comprises an adjusting device and has a plurality of apertures, depressions or recesses. A locking member (5), provided with an actuating device, is guided through the string (1) and can be selectively inserted and removed with its first end, which is remote from the actuating device, into and from the apertures, depressions or recesses. The locking member (5) is also guided through another string (2) on which the actuating device is disposed. The actuating device is supported on the string (2) and co-operates with the second locking end.

摘要： A leg extension means suitable for use in levelling a ladder (31) or other device requiring a level step, work platform or the like is disclosed. The leg extension means comprises a first leg member (32) and a second extending leg member (33) substantially parallel with and in slideable relation therewith. A belt, strap, cable or the like (34) cooperates between the first and second leg members (32, 33) to produce an extendable leg which can be secured or made fast over a range of extended lengths by means of a clamping arrangement (37) which is operable on the belt or cable (34). The clamping arrangement (37) is activated to secure the said belt (34) in order to fix the length of the extendable leg, or is released as required to allow adjustment by way of either extension or contraction of the extending leg member (33) to accommodate variations in the terrain on which the ladder (31) or other device is used. Preferably the clamping mechanism (37) is a ratchet device located on the first leg member (32), the belt, strap or cable (34) being wound about a spool operated upon by the ratchet device (37), the other end of the belt, strap or cable (34) being fixedly attached to the extending leg member (33). The belt, strap or cable (34) preferably passes about a pulley or guide arrangement (36) located on the same member as the clamping mechanism (37), so that pulling on the belt (34) in the vicinity of the clamping mechanism (37), causes the extending member (33) to extend in a direction opposite to the direction of the pull.

摘要： A ladder leveling device having a pair of hydraulic cylinder/piston units (19, 20) to be secured at the outside lower ends of the ladder side rails (16, 18) in manner so that the piston rods (32, 34) of the units extend as ladder supports. The working chambers (43) of the units (19, 20) are in fluid communication with each other through a valved passageway (46) which, when open, allows both piston rods (32, 34) to adapt to an irregular supporting surface while the ladder is oriented in a vertical plane. Upon closure of the passageway (46) to isolate the working chambers (43) of the respective units (19, 20), the piston rods (32, 34) act as rigid extensions of the ladder side rails. Valving of the passageway is effected by an actuating member (46) extending between the side rails (16, 18) in the region of a lower ladder rung (14) so that the member (46) may be depressed to close the passageway by one ascending the ladder in simply stepping on the actuating member.

摘要： A portable ladder especially suited for slopes and uneven ground, comprising a plurality of parallel rungs (2) attached to two side stanchions (3). The ladder is pivotally connected to a supporting base (4) about an axis that is orthogonal (5) to the plane in which the ladder lies and that meets the longitudinal symmetry axis of the ladder, such that the ladder can be inclined in said plane in order to maintain its symmetry axis vertical regardless of the angle of inclination of the plane in which the supporting base lies. In particular, the parallel rungs (2) are further attached to a central stanchion (1) that is hinged to the supporting base (4), the free end of the central stanchion ending with a support tip suited to fix against some structure located at a given height above the ground.

摘要： A ladder having four-point contact with the underlying surface comprises ladder rungs (5), side members or stringers (8) and support legs (6) that are fastened at one end to respective side members (8) for pivoting outwards therefrom. Each support leg (6) independently is rapidly deployable by means of a pressure device (1) acting between the stringer (8) and the support leg (6). The ladder itself may be of any type, but is intended particularly for rescue purposes where time is of critical importance.
