Definitions

  • the invention relates to a ladder hook made of round metal for attaching paint vessels, paint brushes, tools or the like to the side rails of a ladder with three substantially U-shaped arches, each consisting of two legs and a connecting web arc defines an arc plane, and wherein each of the two Leg of the middle U-shaped arc each merges into a leg of the two outer U-shaped arches.
  • Ladder hooks for suspending articles during the performance of a job for which a ladder is necessary, for example a painting job are known in the prior art in various configurations.
  • S-shaped hooks are often used conventionally, one end about a ladder rung and the other end around the handle of the ladder is arranged to be suspended vessel.
  • Such S-shaped ladder hooks not only have the disadvantage that the vessel suspended on such ladder hooks is inevitably located at the back of the ladder but also has the disadvantage that the upper edge of the vessel easily comes into contact with a ladder rung according to its diameter and height.
  • ladder hooks are known from the prior art, which have a central U-shaped arc, which is wrapped around the side spar of a ladder, wherein one of the legs of the U-shaped arc rests on a ladder rung.
  • a leg of an outer U-shaped arc is arranged on each of the two legs of the central U-shaped arc, wherein the respective other arc associated with the middle arc at right angles to the spanned by the middle arch Arc plane are arranged and project forward.
  • a sheet is known for example from GB 2 189 535 A.
  • a corresponding ladder hook is used to receive a paint can holder, in which a paint can be clamped.
  • the arc planes defined by the two outer U-shaped arcs lie in a common plane and that common arc plane forms a right angle to the arc plane of the middle arc.
  • the novel design of the conductor hook now allows to attach the hook on both the left and on the right side of a ladder, where it is fixed there due to its shape so that no slipping or unintentional Hanging out is possible.
  • the advantage of universal replaceability results in particular from the fact that the hitherto customary and commercially available wire hooks are relatively complicated in their shape and can be used only on the right side of a ladder.
  • the conductor hook according to the invention there is the possibility in the conductor hook according to the invention to mount these both on the front side of the side spar and on the back of the side spar and still have the ability to own on the outside and on the inside of the side Holholm objects, such as Tool or a paint bucket to attach.
  • the design of the conductor hook offers the ability to attach items that require support by the side spar due to their lability.
  • objects which can oscillate freely can be fixed to the associated conductor by means of the conductor hook according to the invention. It has proven particularly expedient to design the connecting web of the U-shaped arcs rounded or to design it in accordance with other circumstances so that it is straight.
  • the adjustment of the arches is particularly advantageous for the middle arch, so as to obtain a close contact with the side rail, which can be created by the shape of the U-shaped arch with rounded or square connecting web.
  • the connecting web of the central U-shaped arc has a length of preferably 3 cm and the legs have a length in the range of 6 to 15 cm.
  • the described lengths provide the guarantee that the conductor hook according to the invention can be used in all conventional conductor sizes.
  • the connecting webs of the outer U-shaped arches have a length of preferably 1 cm and the legs have a length of 6 cm.
  • the two inner legs of the outer U-shaped arches which are connected to the legs of the inner bow, bent at right angles from the end of the legs of the central arc, such that the right leg of the left arc and the left leg of the right arc are parallel to each other and the outer legs of the outer left and right arches are outside of the plane spanned by each of an inner leg of the outer arcs and the associated leg of the inner arc layer.
  • the parallel arrangement facilitates in this connection the manufacture of the conductor hook according to the invention, wherein it should be noted that this can be manufactured according to an expedient embodiment, for example of 5 mm round wire material.
  • wires used in the manufacture of the conductor hooks according to the invention are for example made of steel, preferably stainless steel, such as V2A or brass and can also be plastic coated.
  • steel preferably stainless steel, such as V2A or brass
  • V2A or brass can also be plastic coated.
  • square cross sections are conceivable in connection with the production, but preferably a round cross section is preferred.
  • the overall design of the ladder hook ensures that it can be positioned due to the symmetry of its shape both on the right side spar and the adjacent rung and on the left side spar and the adjacent rung. This positioning can be done either from the back or from the front. Depending on the position, both sides of the hook fulfill the locking behind the rung and at the same time the function of the suspension device on the outside.
  • FIG. 1 shows the perspective view of an embodiment of a conductor hook according to the invention
  • FIG. 2 shows a perspective partial view of the side rail of a ladder with conductor hooks arranged thereon according to the invention
  • Figure 3 is a side view of the side rail of Figure 2 with two
  • the conductor hook according to the invention basically consists of three U-shaped arcs, wherein the two legs of the respective arcs, together with the connecting web coupling them, each span a sheet plane.
  • the conductor hook according to the invention has a central arc plane A, which is spanned by the connecting web 1A and the right angles thereto and projecting from this leg 2A and 3A.
  • the legs 2A and 3A are connected at their outer free ends with the respective inner leg of the two outer sheets, said two outer legs 3B and 2C in turn projecting at right angles from the central arc plane A.
  • the two outer U-shaped arcs define a left outer arch plane B and a right outer arch plane C.
  • Both outer arc planes are spanned by the respective connecting webs 1B and 1C and the legs 2B, 3B and 2C and 3C adjacent thereto at right angles. It is essential to the invention that the sheet planes B and C lie in a common plane, which is arranged at right angles to the central sheet plane A.
  • FIG. 2 shows firstly a possibility of suspending the conductor hook on a side rail 4 of a vertical ladder.
  • the U-shaped central arch consisting of the legs 2A and 3A and the connecting web 1A surrounds the side rail 4 of the ladder, wherein the leg 2A rests on a rung 5 of the ladder and wherein in the two outer arc planes B and C respectively exist To arrange objects on the ladder hook both on the inside and on the outside of the respective side spar.
  • the positioning II additionally shown in FIG. 3 is designed in such a way that the outer arc planes B and C to the outside of the side spar of the
  • Ladder hook according to I is possible for attached to the sheets objects is omitted.
