Description

"Grating"

The object whose improvement is sought with the innovation is a grating with intersecting supporting and filler bars and edge strips.

The firing is based on the special task of simplification and to make the skirting board cheaper.

The solution to this problem is essentially characterized by combining the following features that the edge strips Gutter profile bars are, with one leg each in Open upwards, suitable slots of the supporting or cross bars engage and are secured in them at least by static friction are held, preferably such that this leg is held positively in the slots, furthermore the other, outer leg and / or the web of the channel profile bar at least against vertical pressure load on the support or Supports filler rods and / or also the outer leg to secure its position in the position of use of the grating up to can extend into the level of the underside of the grating.

A preferred embodiment of a detail of the above The object is characterized in that the slots

for receiving the inner leg of a channel profile-like Edge strip in a "known manner" in the longitudinal direction "arcuate or similar and the essentially flat legs in the area of the slots whose course is correspondingly deformed »

! Furthermore, a preferred and inventive one is characterized Further development of the above-described subject in that the outer leg of a channel profile serving as a skirting bar with its inside on the end faces of the filling or bearing bars.

These measures are necessary for the arrangement of the edge strips on the grating, only the machine-feasible pressing of the one channel profile bar leg into the one provided for it Slots. But there is also a high degree of stiffness of the Edging guaranteed. The is particularly advantageous The object of hiring for so-called pressed grating, that is, grating in which the cross bars are in slots the support rods are held by positive sing handle, there in this case, the definition of the edge strips, i.e. the pressing of one channel profile leg into the designated in Longitudinal extension mostly approximately arcuate slots, at the same time can be done with the pressing in of the cross bars.

In the drawing, the subject of the invention is shown in exemplary embodiments.
Show it:

Fig. 1 shows a part of a so-called press grating of seen above,

Fig. 2 also in section A-B of Fig. 1,

3 and 4 further embodiments of edge strip fastenings according to the view of Fig.2

Here they have spaced apart and parallel to each other arranged support rods 1 each a plurality of equally spaced and parallel to each other, running essentially transversely to the longitudinal extension of the support rods Slots 2, which run approximately a quarter circle in the area of their base.

Filler rods 3 are held in the slots 2. Almost a longitudinal r side of the grating is a cross-section-like edge strip 4 is provided. The latter has a narrow one and a broad thigh 5 ^ and 6 «while the narrow thigh 5 also like the cross bars 3 arranged near the ends of the support bars Slots 2 is held, the wide leg 6 of the edge strip rests against the end faces of the support rod and extends up to the level of the underside of the grating. The distance between the slots 2 adjacent to the support rod end faces and the End faces do not correspond to the spacing of the cross bars 3 from one another. Furthermore, the web of the edge strip 4 lies on the support rods 1 on.

Under certain circumstances, it could be particularly beneficial to also edge ridges to be arranged in the area of the crossbar end faces, for which purpose the edge strips can be designed as a surrounding frame, which is closed in the area of the front ends of the bearing rod. Furthermore, the frame adjacent to the crossbar end faces can be

human-sized the! filler rods, possibly also their "protrusions, comb-like overlap and similar to the edge strips 4- in the supporting bars 1 must be held.

In Pig. 3 the edge strip, which has a channel profile-like cross-section, has 4 of the same width Leg 5 and 6. While leg 5 in the same It is supported in the same way as in the subject matter of IFig.1 and 2 In this case, the leg 6 on a projecting, material-specific Rabbit 7 of the support rod 1 off.

In Fig. 4 the leg 6 of the edge element 4, the web of which runs at a distance and plane-parallel to the upper side of the support rod 1, extends into the plane of the underside of the grating, so that here too the edge strip 4 of the frame E embedded grating cannot be deformed under vertical loads.
