Насадка на лестницу предназначена для предотвращения соскальзывания и сдвигания лестницы по опоре при работе на высоте, и может быть использована преимущественно при подъеме на деревянные, металлические и железобетонные опоры воздушных линий связи и линий электропередач. Насадка содержит металлическое основание прямоугольного профиля, по краям которого выполнены регулируемые зажимы для крепления насадки на лестнице. На основании неподвижно закреплена U-образная металлическая пластина, выполненная с отводами по краям, с шипами на внутренней части и металлической кольцевой цепью, концы которой закреплены в полукольцах, установленных неподвижно на отводах U-образной металлической пластины. Регулировка прижима насадки к опоре выполняется за счет регулирования длины металлической кольцевой цепи. Для этого, один ее конец может быть закреплен на одном отводе в полукольце неразъемно, а другой конец, на другом отводе, - через карабин, или оба конца металлической кольцевой цепи на обоих отводах закреплены в полукольцах через карабины. В частных случаях выполнения отводы U-образной металлической пластины могут быть расположены или параллельно металлическому основанию, или под углом к металлическому основанию. Насадка обеспечивает две степени защиты: шипы на U-образной металлической пластине предотвращают проскальзывание, а металлическая цепь надежно фиксирует насадку с лестницей на опоре. Тем самым повышается безопасность при работе на высоте. 4 з.п. ф-лы, 1 ил.

Принадлежит: Федеральное государственное бюджетное образовательное учреждение высшего образования "Томский государственный архитектурно-строительный университет" (ТГАСУ)

Полезная модель относится к области обеспечения безопасности работ в связи, энергетике, а именно к устройству насадки для верхней части лестницы для предотвращения сдвигания верхней части лестницы в процессе ее эксплуатации, имеющей в своем составе анкерное устройство, которая, преимущественно, может быть использована для безопасного подъема на деревянные, металлические и железобетонные опоры воздушных линий связи и линий электропередач. Техническим результатом, на достижение которого направлена предлагаемая полезная модель, является повышение безопасности работы на высоте, которая достигается за счет повышения прочности крепления насадки к лестнице. Технический результат достигается за счет того, что в насадку добавлен еще один зажим, который крепит насадку за ступень лестницы и не дает соскользнуть лестнице по оси, расположенной по направлению тетивы. При креплении верхнего края лестницы через насадку надежность сцепления будет обеспечиваться надежностью отдельных элементов насадки и надежностью крепления между собой каждого элемента конструкции. А именно: надежность крепления насадки с лестницей, надежность самой насадки, надежность крепления насадки к опоре. Надежность крепления насадки к опоре и надежность насадки обеспечивается прочностью материалов, из которых они изготовлены. Надежность крепления насадки с лестницей по двум осям координат обеспечивается прочностью материалов, из которых они изготовлены, а вот надежность крепления насадки к тетиве по оси направления самой тетивы обеспечивается только силой зажима и силой трения регулируемых зажимов. Поэтому если зажимы в процессе производства работ немного ослабнут, то при приложении силы, разъединяющей насадку с лестницей по направлению оси расположения самой тетивы, насадка может соскользнуть с самой лестницы. Для того чтобы насадка на лестницу ни при каких обстоятельствах не могла соскользнуть с лестницы в прототип модели добавляется еще один зажим, который крепит насадку за ступень лестницы и не даст ...

The disclosure of the prior application is hereby incorporated by reference herein in its entirety.The present invention relates to step ladders and more particularly pertains to an improvement to an A-frame ladder allowing it to be placed on uneven surfaces.Stepladders are free-standing ladders that can be erected without support from a wall, and can be folded together under transport. A stepladder consists of a step frame, which is pivotally attached to a smaller support frame. The step frame includes a number of rungs, or steps. Steps are climbing supports with “walking and/or stepping surfaces” typically ranging anywhere from 8 cm deep to 2-5 cm. The upper step is often a step-plate or platform, enabling a user to stand and move safely and comfortable. The step and support frames are connected by some locking mechanism that prevents the stepladder from collapsing.The present invention overcomes a limitation of the prior designs, specifically by providing an easy to use mechanism wherein the stepladder is self-leveling.

An Extension Ladder Toolbox comprising: Provisional Patent—61/759,562 Filed—Feb. 1, 2013Inventor: Andrew Mikesell, Sr.The benefit of U.S. Provisional Patent Application No. 61/759,562 (filed Feb. 1, 2013) is claimed, and that provisional application is hereby incorporated by reference.The present disclosure relates to a toolbox designed to be used in conjunction with existing extension ladders in the realm of tool use, protection, and transportation. More specifically, the present disclosure relates to a toolbox that can be easily attached to and detached from an existing extension ladder of the type commonly used by all sorts of workmen at any construction or other site where hand tools and extension ladders are used simultaneously with considerable frequency to accomplish a given task.Typically, workmen use their hands, tool belts or other means to transport tools up and down a ladder so that the tools can be accessed to perform work while the workman is on a ladder. Transporting the tools by hand can be unsafe because the workman's ability to grasp the ladder with his hands can be impeded by the tools in his hands. Transporting tools up and down the ladder via a tool belt or other similar means can be fatiguing to a workman and/or dangerous.For the purpose of promoting an understanding of the principles of the present invention, reference will now be made to the embodiment illustrated in specific ...
