Abstract:
The present invention is directed to a step ladder stabiliser for ensuring a step ladder remains upright when in use, comprising a folding member ensemble which can be stored on the subject ladder and then folds down advantageously in an automated action when the step ladder is opened. The invention derives a central tubular support leg of two sections, with a foot, which extends from the step ladder side at its upper hand rail and two lower mounted supporting tubular struts which also extend from the step ladder but on both sides, to adjoin laterally with the lower section of the support leg at two points. Rotating and pivoting joints at the ends of the leg and struts enable the adjustment of the leg and its gripping foot and also enable the rapid folding away when not in use.
Abstract:
The invention relates to a ladder support device and a method for securing a ladder to a base. The ladder support device comprises a main body, an insert which is attachable to the main body and which is to be pushed into a base, and an anchor portion configured to secure the ladder to the main body. The method for securing a ladder to a base comprises: providing the ladder support device; attaching the insert to the main body and pushing the insert into the base; arranging a shoe of the ladder into the ladder support device so that the anchor portion acts to secure the ladder.
Abstract:
The model regards a portable ladder, of the type that provides for that at the end (13) of at least one of the uprights thereof there be present a plurality of sucker elements (9), susceptible to adhere strongly to the ground following the formation of vacuum beneath the abovementioned elements. Such ladder is characterised in that, at at least one of said uprights a structure (1) is provided, which comprises a cap (2), at whose concave surface facing towards the surface on which the ladder rests there is fixed a plurality of sucker elements (9). Above said cap an element (3) is arranged to which the end (13) of one of the uprights of the portable ladder can be fixed.
Abstract:
An extension ladder (100) includes a plurality of step sections with one section engaged with the adjacent section longitudinally, each having a pair of tubular uprights (101) on both sides connected by a hollow rung (102). The tubular uprights (101) on both sides become gradually smaller in cross-section from the bottom up so that a nested relationship is formed between adjacent two uprights. Each tubular upright (101) is formed with a pin hole to engage with a locking mechanism (104) disposed in the rung (102). The locking mechanism (104) includes a shifting wheel (109, 111), a transmission unit (110, 112) and two locking pins (105) on both ends with a self-locking unit (106), respectively. When the shifting wheel (109, 111) is shifted to pull the transmission unit (110, 112), the two locking pins (105) can move along the axial direction. The extension ladder can be combined to form a straight combination ladder, a platform ladder or a stepladder.
Abstract:
The invention provides a coupling device (1), for a ladder having a bore in a headstock (4) extending between a pair of spaced apart styles, the coupling device (1) comprising: an elongate support member (6) having a mounting region (8) and a working region (7), the mounting region (8) configured to be received within the bore of the ladder to engage therewith, the working region (7) being configured to protrude from the bore and to receive and support a plurality of utility modules; and a releasable detent (9) to secure the elongate support member (6) within the bore, wherein the mounting region (8) is restrained from rotational movement relative to the bore, and the releasable detent (9) prevents longitudinal and transverse movement between the elongate support member (6) and the bore. The coupling device (1) of the invention provides a flexible ladder assembly that is adaptable to variable work environments encountered at the top of a portable ladder when used for access and conducting work.
Abstract:
A stabiliser accessory releasably securable to a ladder having two one piece stiles and at least three rungs extending between the stiles, characterised by an elongate housing to be secured in use to the lower end of the stiles of the ladder and two stabilising arms retractably received within the housing and extendable laterally in opposite directions, when deployed, to contact the ground at points that are further spaced apart than the ends of the housing, wherein the stabilising arms are spring biased in a direction to protrude from the housing and are retained within the housing, and a catch mechanism is provided on the housing to retain the stabiliser arms in the retracted position.
Abstract:
A ladder stabiliser for use with a ladder comprising two stiles positioned against a wall, the ladder stabiliser comprising a body, a securing mechanism for releasably securing the body to the ladder and two or more feet for engagement with a surface wherein the securing mechanism and feet are configured such that in use the feet are located on the surface at points which are distant from the point at which the axes of the stiles intersect the surface. A line between the feet of the stabiliser and the top of the ladder stiles is at an angle of about 55 to 65° to the ground and the ladder is at an angle of 70 to 80° to the ground.
Abstract:
A locking mechanism for selectively securing and unsecuring the linkage of individual ladder sections of a telescopic ladder. The locking mechanism is shifted into a locked position by pivoting a lever toward a first rotational trajectory, urging a track follower in a first direction along a guiding track, and linearly displacing at least one securing rod into an aperture through multiple ladder sections, securing the linkage of the ladder sections. A lever-securing mechanism form-fittingly secures the lever within a bridge element of the locking mechanism when in a locked position. The locking mechanism is shifted into an unlocked position by pivoting the lever toward a second rotational trajectory opposite the first rotational trajectory, urging the track follower in an opposite direction along the guiding track, and linearly displacing the securing rods out from the aperture through the multiple ladder sections, unsecuring the linkage of the ladder sections.
Abstract:
A ladder support apparatus (10) comprising in a base member (12) with a ground engaging part (16) on the underside thereof with a plurality of spikes (20) engageable with the ground. A ladder engaging part (24) is provided on the top side of the base member (12) and includes a plurality of upstanding spikes engageable with the feet of a ladder to prevent slipping thereof.
Abstract:
A ladder assembly having a front frame having a first pair of spatially disposed legs, a plurality of rungs extending between the first pair of legs, and a pivot bracket mounted at the top of the front frame, a rear frame having a second pair of spatially disposed legs, one or more rungs extending between the second pair of legs, and a fixed bracket mounted at the top of the rear frame,, wherein the pivot bracket is attached to the fixed bracket via a single point pivot bracket system configured to pivotally connect the front frame and the rear frame, a folding bracket system configured to keep a correct angle between the front frame and the rear frame, thereby allowing the rotational movement of the legs.
