"Cleaning hook"

The fire concerns a cleaning hook for detachable fastening mainly, of plaster templates and formwork in the construction industry =

Such cleaning hooks are known and consist essentially of an elongated one which tapers to a point in the region of one end Domes and a cantilever arm that can be axially displaced to a limited extent on the latter, which for this purpose in the area of a The end has a hole adapted to the cross-section of the mandrel and can be clamped to the mandrel by tilting also known to design the cross-section of the mandrel and also the hole in the cantilever arm to be polygonal, "Tom Pin hole from the free end of the cantilever arm, this is more or less about following the pin hole to the pin tip bent and ends in a reverse bend directed against the tip of the mandrel, which can also be designed as a scoop can »In the position of use of such a cleaning hook driven into masonry or the like, the the side of the cantilever monkey facing the tip of the mandrel on the mostly wooden template or formwork, and pushes them against the masonry "

Experience has shown, however, that such a bracket for a template or formwork is often not sufficient, especially when if the stencil runs upright and if the formworks attached with such cleaning hooks are shaken Formwork form is filled o

The aim of the innovation is now the security of position: stencils, formwork or the like held with cleaning hooks to increase o

The solution to this problem is characterized by one Cleaning hook with prongs bracing from the side of the cantilever arm facing the mandrel tip in the area of the free end of the cantilever arm or similar

Furthermore, the innovation is characterized in that the above-described The object is the prongs or similar material parts of the cantilever arm »

A preferred and inventive embodiment of the above The object is characterized in that the prongs in two or more in Läagserstreekung the cantilever arm running rows are arranged with teeth which are preferably offset from one another, with preferably furthermore, the prongs are in the form of cones or the like, the cone angle preferably also being approximately 90 ° amounts to.

This is in the state of use of the innovation according to Cleaning hook between its cantilever arm and, for example, one

mostly wooden stencil, with the exception of a non-positive one inevitably also a positive connection achieved, from which a considerable increase in the positional accuracy the plaster template resulted

Identifies to further increase the positional security of an object held with the cleaning hook described above an advantageous and inventive embodiment in that in the area of the free end of the cantilever arm a hole for receiving a nail or the like is arranged, the hole to the central axis: of the dome, for example is rectified.

For this purpose, a further advantageous embodiment of the above-described subject is characterized in that the hole as a line-up hole for the implementation of a line-up bar as a transport device for a number of similar ones Cleaning hook is formed, the line-up rod having a hook-shaped handle which, like the line-up rod with the exception of a preferably molded shoulder or the like provided at the free end as a limit stop For the lined up cleaning hooks, the same, appropriately circular cross-sections over the entire length to have.

Furthermore, an advantageous and inventive embodiment of the above-described subject is to increase the Positional security characterized in that the mandrel tip

has cruciform cross-sections over almost its entire length with preferably approximately plane-parallel web flanks, preferably also want the webs of the mandrel tip in connection with the preferably in a known manner polygonal in cross-section, suitably square mandrel shaft, the corners of which protrude laterally _o

An embodiment of the innovation is in the drawing and is described in more detail below “Es show

Figo 1 shows a cleaning hook in the front view, partially broken open.

Fig. 2 is the same in plan view,

FIG. 3 likewise in section A-B of FIG. 1

Figo 4 the same with transport device,

The one consisting of a mandrel 1, essentially of square cross-section, and one axially displaceable to a limited extent thereon and optionally clampable cantilever arm 2 has existing cleaning hooks in the area of its designed as a bowl 3 free Conical prongs 5 ° formed on the side facing the mandrel tip 4 at the end, the latter are in two rows with teeth arranged offset to one another are provided »Furthermore, a through hole 6 is provided in the cantilever monkey 3, through which a nail 7 in the to be held with the cleaning hook Item 8 can be driven in »This hail 7 thus forms a further point for the form-fitting connection between the cantilever arm 2 and the object 8 «

Through the hole 6, as shown in FIG. in order to be able to transport a large number of new cleaning hooks comfortably and securely »This rowing rod 9 has an eyelet at the bottom as a limit stop 10 and at the top a molded, hook-shaped handle 11 »

To the mandrel 1 relatively easy in masonry or To be able to drive in the like, its tip has 4 cruciform cross-sections with almost plane-parallel web sides 12, the edges of which are rounded »The webs 13 of the mandrel tip 4, which is cruciform in cross-section, are connected to it the square profiled mandrel shaft laterally over its corners as a limit stop for the cantilever arm 2 in front and at the same time form barbs that make it difficult to accidentally detach the dome 1 from the masonry 14 »With 15 is a striking head of the mandrel 1, which at the same time forms the upper limit stop for the cantilever arm 2 »
