  • Patent number: 10927600
    Abstract: An assembly having two safety attachments for attaching to stiles of a ladder that will improve grip of the ladder against a surface it is in contact with during use. Each safety attachment incorporates a gliding channel section and a non-gliding channel section, each formed to accept a range of ladder stile sizes therebetween. The gliding channel section sliding along a screw threaded rod. The screw threaded rod including a rotational thumb nut for positioning the gliding channel section so that the gliding and non-gliding channel sections are in contact with the respective ladder stile. Each safety attachment incorporates a rocking section with a contact face that contacts the surface against which the ladder is placed during use and enables full face contact of the safety attachment over a range of angles between the ladder and the surface against which it rests during use.

  • Publication number: 20200270947
    Abstract: A combination of two safety attachments for attaching to the stiles of a ladder that will improve the grip of a ladder against the surface it is in contact with during use. Each safety attachment incorporates an extended main body to support the components, a gliding channel section and a non-gliding channel section, each formed to accept a range of ladder stile sizes. The gliding channel section of each safety attachment is captured on, and can glide along, a screw threaded rod. Also captured on the screw threaded rod is a rotating thumb nut which is adjusted to position the gliding channel section so that both the gliding and non-gliding channel sections are in contact with the ladder stile to which the safety attachment is fitted.

  • Publication number: 20170096857
    Abstract: A combination of two safety attachments for ladders which incorporates two interchangeable gliding sections, a left hand and a right hand non gliding section, deformable materials, and rod and anti distortion flanged tubes to eliminate distortion and waggling between the assemblies of the gliding sections and non gliding sections. Also incorporated would be two rocking sections and thumb nuts or similar, all having the ability to be married to the upright channel or box section structure of a ladder and characterised by their ability to improve the safety of the ladder by converging and partly sleeving the upright channel or box sections of a ladder and to take a part form of, or partly contour, the surface to which they are set upon or against.
