ABSTRACT:
THE FIELD OF THE INVENTION AND PRIOR ART
The present invention refers to a device for draining gutters.
Such draining gutters are arranged in different kinds of spaces for wet conditions, such as e.g. bathrooms and shower rooms, to receive and drain water, such as bath water and shower water, The floor in these rooms is provided with a wet room isolation element in the form of a waterproof floor covering, which can form the very floor covering when it, for instance, is some kind of plastic carpet or can be coated with the very floor covering, if the room for wet conditions is provided with clinker as the real floor covering. With the expression “floor covering” hereinafter and in the claims, is though referred to said waterproof wet room isolation element, which thus can form the very floor surface or not.
In draining gutters of this sort it is of the uttermost importance that a seal is arranged, which seal prevents the risk for the occurrance of water damages on floor frame works, the very floor covering or other adjacent building elements. Up to this date, such sealings has been obtained as the floor covering has been cut up in the area of the gutter member, so that sections thereof have been possible to fold down into the gutter member and have been applied to the upper sections of the side wall of the latter, for sealing the floor covering to the gutter member. Thereby, it has been necessary to heat the floor covering to remove the tendencies of the sections that have been folded downwards into the gutter member to creep up from the gutter member, and to form these sections so that they bear tightly on the sidewall of the gutter member. To obtain the desired sealing between the gutter member and the floor covering sections folded downwards a clamp ring has been arranged, said clamp ring being insertable from above into the opening of the gutter member, and said clamp ring executing radial forces against the floor covering sections folded downwards when in inserted position.
However, these earlier known devices in draining gutters present important drawbacks. Even when using the above mentioned-procedure for heating the floor covering, which procedure in itself is complicated and forms a considerable drawback, some remaining strains will still exist in said floor covering sections, said strains lending said sections a tendency to strive upwards from the gutter member. In time this unavoidably leads to certain deformations of the floor covering material, such as bulges and the like, through which water that exists in the gutter member is able to, mostly through capillary action, find its way into behind the floor covering sections and in this way cause damages caused by damp on the bottom side of the floor covering, the result of which may be that the complete floor covering of the room for wet conditions must be, substituted, or even on surrounding sections in floor frameworks or other building elements, which might lead to substantially more far-reaching and costlier sanitation operations.
BRIEF DESCRIPTION OF THE INVENTION
The object of the present invention is to provide a device in draining gutters, which sets aside the above mentioned drawbacks of previously known such devices and thereby eliminates the risks for damages caused by damp originating from the draining gutter in a room for wet conditions provided with such a gutter.
According to the invention, the object is obtained by providing the sealing arrangement of the device with means arranged to seal against the floor covering by bearing on said floor covering from above around an upper water receiving opening of the gutter member. Thanks to the sealing means being arranged to bear on the floor covering from above it is no longer necessary to fold said covering down into the gutter member, whereby the floor covering sections located nearest to the gutter member won't have any noticeable inherent movement or deforming forces.
According to a preferred embodiment of the invention the device is provided with members for urging said sealing means towards the floor covering. Hereby, by means of said sealing means, a constantly good and reliable sealing is obtained.
According to another advantageous embodiment of the invention the device is also characterised in that it comprises a ring adapted to surround said opening and, beneath itself, receive the floor covering sections located nearest to the opening, said urging member being arranged to accomplish a force on the ring, said force being directed generally vertically downwards. In this way water located on the floor is thus effectively prevented from flowing beyond the sealing means and reaching the region of the gutter member in any other location than through the upper opening of the gutter member.
According to another, very advantageous embodiment of the invention the gutter member is designed to be releasably connectable to said conduit and arranged to be removable from the floor after removal of the force of said urging members. Hereby it will thus be possible to remove the gutter member and check its condition at suitable times, especially the look of its different seals.
According to yet another embodiment of the invention the device comprises a container-like insert that defines the hole in a floor and, apart from having an opening towards said conduit, is waterproof and adapted to be fixed in relation to the surrounding floor, the gutter member having a smaller dimension laterally and as to depth than the insert and being arranged to form a space between itself and the insert. Hereby is obtained that even if the very improbable would occur, namely that water passes said sealing means, this water will arrive in the space between the gutter member and said waterproof insert, so that thereby no water damage can appear. Thereby the bottom of the insert is preferably provided with a hole which immediately indicates such a leakage by, in a suitable way, draining t he water that comes into the s pace, so that suitable measures for stopping the leakage immediately can be taken.
The invention also refers to a method accomplishing a draining gutter in a room for wet conditions. By this method the accomplishment of a draining gutter in a room for wet conditions is considerably facilitated in relation to previously known such methods as the floor-layer only has to lay the floor surface, and applying the hole therein for said draining gutter can wait until it is time for application of heating, water and sanitation connections in the room for wet conditions, as this easily can be done by a non-professional in the floor-laying field. From this follows that the gutter member doesn't need to be arranged in place before the final finishing of the room for wet conditions through the applying of said heating, water and sanitation connections, so that the risks for the gutter member to get broken or hurt in any other way in a building work place are considerably reduced.
Further advantages and advantageous characteristics of the invention will appear from the following description and the rest of the enclosed claims.
