The invention relates to a gutter system (1) comprising at least one frame unit (10), at least one cover unit (20) and at least one securing element (30), wherein the frame unit (10) comprises at least one receiving area (12) for arranging the cover unit (20), and wherein the securing element (30) is adapted to engage in the cover unit (20) and to releasably engage in the receiving area (12) so the cover unit (20) can interlock in the receiving area (12) of the frame unit (10). The invention also relates to a cover unit (20) and a securing element (30).

A connector pipe screen device configured for mounting on a water conduit includes an expandable ring mounting assembly, the expandable ring mounting assembly being configured to be engagable with and securable to the conduit near or at an axial end of the conduit at which a conduit opening is disposed, a back plate mounted on the expandable ring mounting assembly and a front cover mounted on the back plate. The front cover has a perforated portion defining a multiplicity of openings formed therein to allow water to pass through the perforated portion and to prevent debris carried by the water from passing through the perforated portion.

The invention relates to a gutter system (1) with at least one frame unit (10), at least one cover unit (20) and at least one first damping element (14), wherein the frame unit (10) has at least one receiving area (12) for arranging the cover unit (20). The receiving area (12) of the frame unit (10) has at least three side walls (12.1; 12.2; 12.3; 12.4; 12.5), wherein the first damping element (14) is provided between the frame unit (10) and the cover unit (20) in such a way that the cover unit (20) is received in the frame unit (10) in a damping mariner in at least three spatial directions.

The invention relates to a locking element (11) for securing a grate (3). The locking element (11) comprises a spring element (113) kept between a cover element (111a) and a spring support element (117). The spring support element (117) is displaceable relative to the cover element (111a) by means of an actuating element (115). The displacement of the spring support element (117) causes a movement of at least one of the ends (113a, 113b) of the spring element (113) relative to the cover element (111a).

A stable and variable design of a drainage structure includes a drainage body (11) and a cover (20). The cover (20) has engagement devices (13, 13′; 14, 14′; 23, 23′) when seen in a longitudinal direction of the drainage body (11), whereby the cover connects upper edges (12, 12′) of the drainage body (11) to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers (20) for different loads, for example while using the same drainage body (11), two types of engagement devices (13, 13′; 14, 14′) are provided on the drainage body.

The invention relates to a locking element (11) for securing a grate (3). The locking element (11) comprises a spring element (113) kept between a cover element (111a) and a spring support element (117). The spring support element (117) is displaceable relative to the cover element (111a) by means of an actuating element (115). The displacement of the spring support element (117) causes a movement of at least one of the ends (113a, 113b) of the spring element (113) relative to the cover element (111a).

A connector pipe screen device configured for mounting on a water conduit includes an expandable ring mounting assembly, the expandable ring mounting assembly being configured to be engagable with and securable to the conduit near or at an axial end of the conduit at which a conduit opening is disposed, a back plate mounted on the expandable ring mounting assembly and a front cover mounted on the back plate. The front cover has a perforated portion defining a multiplicity of openings formed therein to allow water to pass through the perforated portion and to prevent debris carried by the water from passing through the perforated portion.

A drain lock sealing apparatus is positioned in a drain pipe for being locked therein and further for sealing the pipe to prevent odors and vermin from coming from the drainpipe into the room. The apparatus includes a grate positioned over the drain pipe, a resiliently deformable sealing ring extending from the grate into the drainpipe, an rigid expander member with an inwardly tapered outer surface extending into the sealing ring, a resiliently deformable frusta-conical member attached to center hub of the expander member so that the peripheral closure edge of the frusta-conical member is in non-fixed normally closed relationship against the circumferential edge of the expander member so that the closure edge opens in response to liquid passing through the grate into the drain and resumes normally close relationship in response to the secession of liquid passing through the grate. A bolt extends through the grate and cylindrical sealing ring and is screwed into the axial hole whereby tightening of the bold compresses the sealing ring axially to deform the cylindrical sealing ring radially into clamping engagement against the interior surface of the drain pipe.

A trench drain assembly includes a cross-bar that can swivel into arcuate guides in the sidewalls of the trench drain assembly and a grate clip assembly for reversibly attaching a grate to a cross-bar, whether of the swivel in type described herein or a cross-bar of a different style.

The invention relates to a gutter system (1) with at least one frame unit (10), at least one cover unit (20) and at least one first damping element (14), wherein the frame unit (10) has at least one receiving area (12) for arranging the cover unit (20). The receiving area (12) of the frame unit (10) has at least three side walls (12.1; 12.2; 12.3; 12.4; 12.5), wherein the first damping element (14) is provided between the frame unit (10) and the cover unit (20) in such a way that the cover unit (20) is received in the frame unit (10) in a damping manner in at least three spatial directions.
