Definitions

  • the invention relates to a step stool with legs which can be connected by means of a bracket and on which support bars and at least two steps are articulated.
  • step stools of the type mentioned have a clear height of about 140 cm when folded.
  • the legs run parallel to the support bars, and the treads are in the plane of the legs and are arranged between them.
  • the transport of such a step stool within an apartment or in the garden is cumbersome because the user holds the step stool in the area of the bracket, which is associated with an unfavorable position of his arm.
  • the invention has for its object to further develop the generic step stool without undue design effort so that it can be easily and conveniently transported by the user.
  • the object is achieved in that the top one, between an effective and a ineffective position, in which it runs approximately parallel with the legs, swiveling step carries a handle, the distance to the bracket is less than the arm length of the user.
  • the invention is implemented in any case when the uppermost step has a handle which, when the step stool is folded, is arranged below the bar and is dimensioned such that the user can hold the handle while the step stool is being transported while the bar is in Area of his armpit is arranged.
  • a particularly useful embodiment provides for a step stool with an arch-shaped bracket that the handle has the shape of a bracket. It is expedient if the handle is arranged in the region of the broad side of the step facing the bracket. Due to the arched design of the bracket and the handle, it is possible to hold the handle properly even if the top point of the bracket is located outside the armpit. It is also provided that the handle can be releasably connected to the step. This measure makes it possible to retrofit conventional step stools and to train them in accordance with the invention. Alternatively, it is possible to design the handle as an integral part of the step.
  • the distance between the handle and the bracket is variable and adjustable is. This measure is particularly important if the distance between the handle and the bracket is not matched to the arm length of the user. By adjusting the distance, it is possible to optimize the position of the bracket.
  • a step stool 10 is shown with legs 12 and 14 connected by means of a bracket 38, to which support bars 16 and 18 and two steps 32 and 34 are articulated.
  • the legs 12 and 14 and the bracket 38 are formed in one piece, the radius of the bracket 38 corresponding to approximately half the distance between the two legs 12 and 14 from each other.
  • the upper step 34 which is pivotable between an effective and an ineffective position of use and is arranged between the legs 12 and 14, runs approximately parallel with these legs when the step stool is folded, which is shown in FIG. 2.
  • This step 34 carries a handle 36, the distance to the bracket 38 is less than the arm length of a user.
  • the handle 36 has the shape of a bracket and is arranged in the region of the broad side 35 of the step 34 facing the bracket 38.
  • the step 34 is connected to the step 32 via two rods 42 and 44 which are articulated in the area 40 and 46 to the step 34 and 32, respectively.
  • the step 34 is carried by a rod 43 which is connected to the legs 12 and 14.
  • the lower step 32 is carried by the rod 30.
  • the support bars 16 and 18 are articulated to the legs 12 and 14 in the area 39.
  • the support bars 16 and 18 are connected by means of a bracket 20 which carries two support bodies 26 and 28, via which the support bars 16 and 18 can be supported on the ground.
  • the legs 12 and 14 are supported on the floor by support bodies 22 and 24.
  • the handle 36 is releasably connectable to the step 36 and is designed such that its distance from the bracket 38 can be changed.
