Ground water drain

DETAILED DESCRIPTION It is an object of the present invention to provide a ground water drain, the grating of which is made from a higher elasticity material but is held in the frame by a positive fastening.
It is a further object of this invention to provide a grating constructed in a substantially rigid manner but however provided with such elasticity that it only acts in the direction of crossbars of the grating, i.
e.
at right angles to the direction of the traffic travelling over the grating.
This and other objects of the invention are attained by a ground water drain including a grating formed from bars and having at least one central bar extending over a ground opening, and on which are transversely arranged crossbars, whereof certain spaced apart bars are provided with a projecting portion and which crossbars, accompanied by an elastic deformation of the central bar, can be locked solely with the projecting portions in corresponding holding portions provided in the frame, with the formation of a positive fastening.
Thus, the crossbars, which essentially cover the entire grating surface, can have a rigid construction, whereas the central bar or bars are elastically deformable for the insertion into and removal of the grating from the frame.
The invention is described in greater detail hereinafter relative to non-limitative embodiments and the attached drawings.
