Definitions

  • the invention relates to a leaning device for a stair ladder.
  • the task is based on the practical value of a stair ladder increase.
  • a leaning device the stair ladder can be installed above the last step or is mounted, and at least one trough with contact surfaces for the legs a user of the stair ladder, the contact surfaces between opposite spars of the stair ladder can be positioned or positioned are.
  • a user can, if he is on a the upper steps of the stairs, lean his legs against the leaning device, being given lateral support in particular. This will in particular stability when working overhead. This will also increased when bending over.
  • the leaning device according to the invention can be an integral part of a stair ladder be or, for example, also be designed as an attachment element, by means of which a stair ladder can be retrofitted.
  • the at least one investment trough is so is designed so that it gives lateral support and forward support to one leg. On The user can then use his legs in the investment trough or the investment troughs lean, increasing stability.
  • one is used to form the at least one investment trough Side leg provided, by means of which a leg, which is in the recess is ajar, at least partially can be surrounded laterally. Such a Side legs can then at least partially grasp the leg to the side to give lateral support.
  • An investment trough is in particular two Side thighs assigned to both sides for lateral support to care.
