Abstract

The device consists of a displacement part (1) shaped like the recess etc. in a cover (2), and fitted into it positively and/or non-positively. It is of environmental pollution-resistant elastic plastic, e.g. plastic foam. When fitted, its surface is aligned with the cover surface. The part contains a transponder to store information concerning fittings, performance, and/or other parameters. It is mainly sickle-shaped with an elliptical surface having a recessed part to engage under the bridge (5) in a cover. It has a slide coating or lubricant on the underside, and may be removed by a tool or a hydrant key (7).

Description

The The invention relates to a device for protecting tools to engaging recesses or similar recesses in mechanical removable and removable caps, caps, lids or the like, especially for use with street cap lids for underground hydrants or the like Shut-off valves, according to the generic term of protection claim 1.

Underground hydrant to connect a standpipe are used to supply fire fighting water to cities and Communities and enable as well as fire hydrants above ground water withdrawal from the public Water mains.

Underground hydrant have the disadvantage that in many cases they are caused by snow or ice are frozen and therefore often cannot be used. Furthermore shows up with longer Do not press the cap of the street an underground hydrant or similar shut-off valve that the lifting opening with cross bar for attaching the hydrant key dirty or in other What is added by the employees of the Waterworks, the cities as well as emergency services the fire departments criticized as a disadvantage becomes.

In many cases is therefore more or less regularly e.g. with high pressure cleaning devices tried the cap of the street common to keep. However, it has been shown that the usual Recesses flushed out of public traffic areas in street cap lids are soiled and clogged relatively quickly with the then mentioned above disadvantages.

Out the aforementioned is therefore an object of the invention, a device to protect against contamination of tools Troughs or similar recesses in mechanically removable and removable Caps, in particular street cap lids, to specify which ensures that the correspondingly equipped underfloor hydrants, Sliders or similar devices are accessible at all times.

The Device to be created should be inexpensive to manufacture and on site be easy to use so that it can spread quickly can.

The solution The object of the invention is achieved by a device for protection of depressions or the like to be gripped behind by a tool Recesses in mechanically removable and removable caps, sealing hoods, Lids or the like and in particular for the use of street cap lids for underfloor hydrants or similar Shut-off valves, according to the characteristics of protection claim 1, wherein the subclaims at least useful embodiments and Training includes.

According to the invention Dirt shifting part with a shape complementary to the trough or other recess inserted into this and fixed there positively and / or non-positively.

The shifting part consists of an environmentally resistant, preferably elastic plastic material and closes in the inserted state with its top side essentially with the upper lid surface flush from.

at a preferred embodiment the displacement part consist of a plastic foam material of specified hardness.

In a further embodiment of the invention there is the possibility in the displacement part a transponder for storing information about the respective valve, its performance or other parameters embed. This is particularly advantageous if there are signs missing or for certain reasons are not recognizable. About that there is also the possibility storing a much larger amount of information in a transponder, the one above in addition in a simple way with a portable terminal from it authorized forces can be read out.

If in particular the displacement part to Use in street cap lids Is used, this is designed as a sickle-shaped body, the cross section has an elliptical shape and the elliptical surface is one return has whose depth and width dimension to the dimensions of the lifting bridge is matched in the lid.

This such a shaped displacement part becomes then inserted into the existing recess in the road cap cover and kept safe.

in the Use case with the help of a simple tool, in particular a hydrant key, the displacement part from the hollow in the street cap lid be pushed out, so that then the lid in the usual way with the help of the hydrant key can be lifted off and removed.

To the easier removal of the displacement part from its seat this can have a sliding coating on its underside have or be provided with a lubricant.

The Top of the extrusion has a structuring structure for easier and safer Attaching a tool.

at An alternative of the invention is the possibility of the displacement part in the trough or recess, in particular of a road cap cover on site by foaming to form, whereby for easier removal of the displacement part a release agent in advance into the trough from the cover recess Recess, for example sprayed or brushed on or is applied in any other way.

The Opening trough dirt displacer proposed according to the invention is preferred filling from plastic foam, as explained the opening trough in street cap lids almost complete and thus prevents contamination or icing.

By This measure underfloor hydrants or sliders are accessible at all times. Due to the properties of the preferred plastic foam material for the shifting part let yourself this at any time, if access to the hydrant is desired, using a tool, especially the hydrant key press together or entirely Push out.

The Invention is intended below using an exemplary embodiment and under With the help of figures closer explained become.

in this connection demonstrate:

1 a dirt displacer according to the invention in perspective view;

2 a plan view of a road cap cover with inserted displacement part;

3 a sectional view of a road cap cover with inserted displacement part and

4 a representation of how the displacement part can be easily removed with the aid of a hydrant key, thereby ensuring unimpeded access to the opening recess of the road cap cover in use.

The Indian 1 shown dirt displacer, hereinafter as a displacement part 1 denotes, in one embodiment, suitable for street cap lids 2 a sickle shape, the cross section of the displacement part 1 is approximately elliptical. The surface 3 of the displacement part 1 has a return 4 , whose depth and width measure to the dimensions of the lifting bridge 5 in the street cap cover 2 is coordinated.

According to the illustration 2 becomes the dirt displacer or the displacement part, which consists of a preferably elastic plastic material 1 in the relevant recess in the street cap lid 2 used and is essentially flush with the lid surface.

If in use the road cap cover 2 To establish access to the respective hydrant or slide must be removed using a tool, for example a conventional hydrant key 7 , the displacement part 1 from its the recess 6 completely or partially pushed out filling position, as this with the help of 4 is illustrated. After that you can use the hydrant key 7 then the respective street cap cover 2 with leverage over the web 5 , which acts as a counter bearing, can be lifted off and removed.

It is within the meaning of the invention that, in the case of deviating shapes of the troughs or recesses in a road cap cover, a correspondingly complementary shape for the displacement part 1 is chosen.

In an embodiment not shown in the figure, the displacement part 1 not manufactured as a separate part in advance, but realized by foaming on site in a cleaned recess or recess in a street cap cover. For this purpose, a release agent is sprayed in first. This is followed by foaming the respective recess in the lid. Before the plastic foam material has completely hardened, the top is pulled off so that the surface of the web in question remains free.
