Description

The invention relates to a gutter system with at least one frame unit, at least one cover unit and at least one first damping element according to the preamble of patent claim 1. Such a gutter system discloses the WO 2005/035889 A1 .

In conventional gutter systems for drainage, the cover or grate unit is connected or interlocked with the frame unit. This is intended to secure the grate or cover unit in the frame unit against falling out and/or being lifted out.

However, thick-walled gutter systems in particular require a large grate width and thus increased costs in the production of such cast iron grates. Furthermore, the frame unit or the gutter wall itself must be modified and designed with additional geometries so that intervention in the wall is possible. In addition, the fact that the cast iron grate or the cast iron cover rests directly on the frame unit causes the grate to be unstable.

It is an object of the present invention to provide a gutter system which is simple and cost-effective to manufacture, provides an optimized grate or cover support, enables easy assembly on site and at the same time provides easy maintenance.

This object is solved by the subject matter of claim 1. Preferred embodiments are specified in the dependent claims.

The invention relates to a gutter system with at least one frame unit, at least one cover unit and at least one first damping element, wherein the frame unit has at least one receiving area for arranging or receiving the cover unit, wherein the receiving area of the frame unit is formed by at least three side walls, preferably by five side walls. The first damping element is provided between the frame unit and the cover unit in such a way that the cover unit is received in the frame unit or in the at least one receiving area of the frame unit in a damping manner in at least three spatial directions, preferably in at least five spatial directions.

The invention is based on the basic idea that the frame unit has an area for positioning and receiving, which is designed by means of a first damping element in such a way that an inserted cover or grate unit is damped in at least three spatial directions when used as intended. This means that a quiet grate or cover position can also be provided, for example for cast iron cover and frame units of a gutter system.

According to the invention, the at least one receiving area can be formed by at least three side walls. In particular, the cover unit can be inserted into the receiving area of the frame unit. The cover unit can thus rest in particular on a first, second or third side wall.

Preferably, the at least three side walls of the at least one receiving area are designed such that the cover unit is encompassed on three sides.

Particularly preferably, the at least one receiving area can be designed with five side walls, so that the cover unit can be inserted into the receiving area via one side and is encompassed on five sides by the side walls of the receiving area.

Furthermore, the first damping element between the frame unit and the cover unit is designed such that the cover unit is mounted in the frame unit in a damped manner in at least three spatial directions. Preferably, the cover unit can be mounted in the at least one receiving area in four spatial directions or be dampened or absorbed in five spatial directions.

When two opposing receiving areas of the frame unit are formed for the two-sided reception or storage of the cover unit, this results in a dampened storage or reception of the cover unit in at least four spatial directions, preferably in all six spatial directions.

It is particularly preferred that the cover unit is mounted in the frame unit in a damped manner in the vertical upward direction and in the longitudinal direction of the gutter system on both sides, in accordance with the alignment or orientation for use. This results in damping along three sides or spatial directions and in particular a shifting protection of the cover unit in the longitudinal direction of the gutter system.

When designing a gutter system with a circular cover unit, it may also be possible to provide a dampened support for the cover unit with a single support area of the frame unit.

In accordance with the present invention, the at least one first damping element is formed in the receiving area of the frame unit in order to provide a dampened mounting of the cover unit in several spatial directions. This makes it possible to achieve a steady grate position or cover position for the gutter system.

According to one embodiment, the receiving area of the frame unit with the at least three side walls is designed as an undercut, so that the cover unit is at least partially encompassed by the frame unit along at least three sides.

The cover unit can thus be inserted into the undercut receiving area of the frame unit, whereby the cover unit is essentially prevented from falling out or being lifted out by the undercut geometry. Rather, it is preferably provided that the receiving area only allows the cover unit to be removed in the opposite direction to the direction in which the cover unit is inserted.

In particular, by designing the at least one receiving area of the frame unit with at least three side walls as an undercut, a locking, anti-displacement and damping function for the cover unit can be provided.

This allows a safe and practical arrangement of the cover unit in the frame unit.

In a further embodiment, the cover unit has at least one engagement element for engaging in the receiving area of the frame unit. In particular, the engagement element can be designed as a nose-shaped projection on the frame unit. This allows the cover unit to be securely inserted and positioned in the corresponding receiving area of the frame unit.

According to the invention, the cover unit is designed in combination with at least one movable securing element, so that the movable securing element can be moved for at least temporary engagement in the receiving area of the frame unit. In particular, the securing element can be movable in translation or can be movable in rotation by at least 90°.

In this sense, the cover unit can have a movable securing element and a stationary engagement element.

The securing element can be designed, for example, as a spring-mounted interlocking element or a screw-shaped interlocking element for engaging underneath or behind the receiving area or the undercut receiving area. In particular, the at least one securing element of the cover unit can be designed as a sliding bolt, a spring-snap bolt in the sense of a door lock principle, as a sash or the like.

According to one embodiment, the at least one first damping element is provided along at least three of the side walls of the receiving area of the frame unit, or as an attachment for arrangement on the cover unit, in particular on the at least one engagement element.

Thus, a dampened mounting or reception of the cover unit in the at least one receiving area can be provided in at least three spatial directions, preferably in five spatial directions, by the side walls being able to be designed with the first damping element.

Alternatively, the at least one first damping element can be formed along the cover unit. In particular, the at least one engagement element of the cover unit can be formed with the first damping element, so that damping can be provided between the frame unit and the cover or grate unit in at least three spatial directions, preferably five spatial directions.

In one embodiment, the at least one first damping element is provided as a surface coating or as at least one insert for positioning along the receiving area.

The first damping element can be designed or applied in the form of a surface coating, in particular along the three side walls in the receiving area of the frame unit. Furthermore, it is possible for the first damping element to be provided as an insert that is at least temporarily introduced into the receiving area along the side walls.

Alternatively, the at least one engagement element of the cover unit can have a surface coating or an attachment for providing the first damping element in the sense of the invention. Furthermore, it is conceivable that the at least one engagement element consists, for example, of a polymer and acts entirely as the first damping element.

In one embodiment, at least one second damping element is provided along a side surface of the cover unit facing opposite the frame unit, preferably on a side of the frame unit opposite the arranged first damping element, in particular in the assembled state of the gutter system.

In particular, the second damping element can be applied as a surface coating or a surface layer on the cover unit, so that at least one of the side surfaces facing opposite the frame unit is dampened. Thus, additional damping is available, in particular in one spatial direction, by means of the second damping element along the cover unit.

It is also possible to provide two-sided damping of the cover unit using the second damping element.

According to a preferred embodiment, the first damping element and/or a second damping element are arranged such that the cover unit is dampened and mounted on side walls of the receiving area in the longitudinal direction of the gutter system in the frame unit.

In this way, in particular, a displacement of the cover unit in the longitudinal direction of the channel system can be prevented and/or dampened. As a dampening in at least a third spatial direction, for example, a dampening in a vertical direction upwards can be provided.

According to a further preferred embodiment, the first damping element and/or a second damping element comprises a plastically and/or elastically deformable material, in particular a polymer.

Particularly advantageously, the damping element can have a plurality of recesses into which corresponding thickenings of the cover unit engage, thus enabling the damping elements to fit securely on the cover unit. In addition, the at least one damping element can have an undercut on its upper and/or lower leg in order to further improve the attachment to the thickenings of the cover unit.

The cover unit and the frame unit can be made of metal, in particular cast iron, or of comparable, suitable materials for forming a gutter system for drainage.

Accordingly, a plastically and/or elastically deformable material of the at least one first and/or second damping element can provide an appropriate damping between the frame unit and the cover unit, among other things to achieve a quiet grate or cover position.

According to a further embodiment, the frame unit has at least one displacement lock by means of an insert as the first damping element, wherein the insert engages in the cover unit in such a way that a displacement lock is provided in the longitudinal direction of the gutter system.

The at least one displacement lock can be designed to cooperate or engage with the at least one engagement element of the cover unit.

Alternatively, along the extension of the at least one, preferably undercut, receiving area in the direction of a longitudinal axis of the channel system, anti-displacement elements can be provided, for example in the form of support ribs or intermediate ribs or the like. Thus, different sections of a longitudinally extending receiving area of the frame unit can each be designed with five side walls.

A suitable mechanism to prevent the lid or grate unit from sliding can be provided.

In one embodiment, the frame unit is designed symmetrically to a longitudinal axis of the gutter system.

The cover unit can be used alternately with the frame unit, whereby the cover unit can be designed asymmetrically. A direction-dependent joining of the cover and frame unit is preferably not provided.

In the following, the invention is explained in detail with reference to the accompanying drawings.

Various views of a fifth embodiment of the gutter system, in particular representation of the securing element.

In Fig.1 a cross-sectional view of a gutter system 1 according to a first embodiment is shown. The gutter system 1 has a frame unit 10 and a cover unit 20.

The frame unit 10 is provided with undercut receiving areas 12 on both sides. The receiving areas 12 are formed by at least three side walls using a first, second and third side wall 12.1; 12.2; 12.3.

A first damping element 14 is provided along the three side walls 12.1; 12.2; 12.3. The first damping element 14 can be a surface coating or an insert 16 (cf. Fig.2 ) should be provided.

The lid or grate unit 20 has according to Fig.1 at least one engagement element 22, which is provided for engagement in an undercut receiving area 12 of the frame unit 10. The first damping element 14 is formed between the frame unit 10 and the cover unit 20.

The cover unit 20 can be formed on one side or both sides with at least one engagement element 22. According to Fig.1 a one-sided design of the engagement element 22 on the cover unit 20 is provided. In this sense, the cover unit 20 can be designed asymmetrically.

Furthermore, according to Fig.1 a force-fitting and/or form-fitting connection of the cover unit 20 to the frame unit 10 is provided. For this purpose, the frame unit 10 has first bracing elements 18, which can be designed as a V-shaped groove symmetrically along a longitudinal axis of the channel system 1. This enables a reciprocal or direction-independent arrangement of the cover unit 20 on the frame unit 10.

The cover unit 20 has at least one securing element 24, in particular in the form of a snap hook with a V-shaped nose for engagement in one of the first tensioning elements 18. According to Fig.1 the at least one securing element 24 is provided on the side of the cover unit 20 opposite the engagement element 22. In this way, a detachable force-fitting and/or form-fitting connection between the cover unit 20 and the frame unit 10 can be expediently provided.

By Fig.1 the formation of the engagement element 22 and the at least one securing element 24 is provided on opposite sides, a force-fitting and/or form-fitting connection between the frame unit 10 and the cover unit 20 can be brought about in the sense of an at least partially rotational movement of the cover unit 20.

In Fig.2 is a perspective view of an insert 16 for use with a gutter system according to Fig.1 shown.

The insert 16 can be introduced into one of the receiving areas 12 of the frame unit 10. In this sense, the insert 16 can provide dampened side walls 12.1; 12.2; 12.3; 12.4; 12.5 in different spatial directions, at least in three spatial directions, or serve as damping for intermediate ribs along the receiving area 12.

Furthermore, any arrangement of several inserts 16 along the receiving area 12 is possible, in particular depending on the positioning of the securing elements 24 along the cover or grate unit 20.

In the fig. Fig. 3a-d different views of a second embodiment of the gutter system 1 are shown.

In particular, Fig. 3a the cover unit with two securing elements 24 and two first damping elements 14, which are each spaced apart from one another in the longitudinal direction of the gutter system 1.

The first damping elements 14 are therefore provided for section-wise damping of the cover unit 20 along the receiving area 12.

In particular, damping can be provided in the longitudinal direction of the channel system 1, opposite the fourth and fifth side walls 12.4; 12.5 of the receiving area 12, which can be divided by intermediate ribs or the like. The intermediate ribs can be understood as fourth and fifth side walls 12.4; 12.5. Such intermediate ribs can also be used to provide dampened protection of the cover unit 20 against slipping in the longitudinal direction of the channel system 1.

In Fig. 3b the positioning of the engagement element 22 in the at least partially undercut receiving area 12 of the channel unit 10 is shown. In this way, the cover unit 20 cannot be removed from the frame unit 10 in an exclusively vertical direction. The engagement element 22 and the receiving area 12 represent a detachable interlock.

In Fig. 3c a dampened mounting of the cover unit 20 or the engagement element 22 in the receiving area 12 of the frame unit 10 is shown.

In particular, the engagement element 22 is encompassed by the first damping element 14 or the first damping element 14 is arranged on the engagement element 22. In this way, damping can be provided in particular with respect to the first, second and third side walls 12.1; 12.2; 12.3 of the receiving area 12 of the frame unit 10.

In Fig. 3d the damped mounting of the engagement element 22 in the receiving area 12 divided by intermediate ribs is shown.

In particular, the first damping element 14 surrounds the engagement element 22 of the cover unit 20 in such a way that a displacement lock in the longitudinal direction of the gutter system 1 is provided in a dampened form.

In the Fig. 4a-b various views of a third embodiment of the gutter system 1 are shown. In particular, a design of the securing element 24 in the sense of the embodiment according to Fig.1 illustrated.

The securing element 24 engages in a force-fitting and/or form-fitting manner in the undercut receiving area 12 of the frame unit 10. Furthermore, the securing element 24 engages with a V-shaped nose in the first bracing element 18, which is provided below the receiving area for bracing the securing element 24 in combination with the cover or grate unit 20. In this way, an interlocking of the cover unit 20 on the frame unit 10 can be provided.

In particular, the at least one first bracing element 18 can be arranged below the receiving area 12 on the frame unit 10 and cast or encapsulated.

Preferably, the frame unit 10 with the receiving areas 12 on both sides can be designed symmetrically, so that the cover unit 20 with the engagement elements 22 and the securing elements 24 can be inserted on both sides or alternately or independently of direction.

In the Fig.5 a cross section of a fourth embodiment of the gutter system 1 is shown, in particular a representation of the securing element 24. In the Fig.6 Various further views of the fourth embodiment are illustrated.

According to the Fig.5 and 6 the securing element 24 is designed as a rotationally movable securing element 24.

In particular, the securing element 24 is accommodated in a receiving opening 20.3 of the cover unit 20 so as to be rotatably movable or is clipped onto a rotation shaft of the cover unit 20.

The rotation axis of the securing element 24 is aligned on the cover unit 20 in the longitudinal direction of the channel system 1 and is provided directly adjacent to the receiving area 12 on the cover unit 20. In this way, the securing element 24 can engage or rotate into the undercut receiving area 12 of the frame unit 12 during a locking rotation.

At an opposite end of the securing element 24, which in the locked state projects towards a central region of the channel system 1, a locking lug according to Fig.6 trained.

The locking lug of the securing element 24 can engage with a first bracing element 18 for locking or interlocking, which is formed on the cover or grate unit 20 in the form of a projection.

In this way, the securing element 24 can be locked in a blocking position or locking position on the bracing element 18, wherein the securing element 24 engages in the undercut receiving area 12 on the opposite side of the rotation axis. Thus, the cover unit or the grate unit 20 and the frame unit 10 are connected by means of the securing element 24 in accordance with Fig.5 and 6 can be conveniently interlocked with one another.

The Fig. 7a-d show various views of a fifth embodiment of the gutter system 1, in particular a representation of the securing element 24.

According to Fig. 7a the release area 24.3 is formed centrally in the transverse direction of the securing element 24. Furthermore, the securing element 24 can be designed such that it only partially closes the receiving opening 20.3. Several securing elements 24 are provided spaced apart from one another in the longitudinal direction of the gutter system 1.

In Fig. 7b a cross-sectional view of the fifth embodiment is shown.

The frame unit 10 is designed with the receiving area 12 for storing and receiving the cover unit 20. The receiving area 12 is at least partially designed as an undercut or undercut.

The cover unit 20 has a receiving opening 20.3 for storing and receiving the securing element 24. Essentially, the receiving opening 20.3 can enlarge at least in sections from top to bottom, along the orientation of the cover unit 20 in normal use. In this way, waste or dirt that can enter the receiving opening 20.3 from above can fall through the cover or grate unit 20.

In addition, the receiving opening 20.3 is formed with a support surface 20.2 in a central region of the cover unit 20 or the channel system 1. The support surface 20.2 runs essentially in a vertical direction and has a radius or a rounding at least at its lower end.

Furthermore, the frame unit 20 has at least one bearing element 20.1. The bearing element 20.1 extends according to Fig.1 longitudinally and transversely to the longitudinal direction of the gutter system 1. In particular, the bearing element 20.1 can be designed to be slightly inclined relative to the horizontal.

The bearing element 20.1 can have a loss prevention device 20.4 at one end, in particular in the direction of the central region of the channel system 1. The loss prevention device 20.4 can be designed as a bead or bulge along the bearing element 20.1. This provides a force-fitting and/or form-fitting connection between the cover unit 20 and the securing element 24. Captive interlocking is provided.

The securing element 24 is in accordance with Fig.1 inserted into the lid or grate unit 20 and engages with a first end in a force-fitting and/or form-fitting manner in the receiving area 12 of the frame unit 10. Since the securing element 24 is designed with a bevel along its underside at this first end, the securing element 24 can be snapped into the receiving area 12 of the frame unit 10 in a simplified manner.

The securing element 24 is designed with at least one bearing groove 24.1, which is designed to correspond to the bearing element 20.1 of the receiving opening 20.3 of the cover unit 20. The bearing element 20.1 can thus engage in the bearing groove 24.1 in a force-fitting and/or form-fitting manner for sliding reception. The securing element 24 can be supported and guided by the cover unit 20.

Furthermore, the securing element 24 has a locking lever 24.2 at a second end, which is arranged in the middle area of the gutter system 1. The locking lever 24.2 is elastically and/or plastically deformable. In particular, the locking lever 24.2 is provided in such a way that it can be supported against the support surface 20.2 of the cover unit 20 in order to apply a closing force to the securing element 24 and thus ensure that it snaps into place or engages in the receiving opening 12 of the frame unit 10.

The securing element 24 can be regarded as a spring-loaded securing element 24 with regard to the preferably elastically deformable locking lever 24.2.

Furthermore, the securing element 30 has the release area 24.3, which is intended for engagement with, for example, a screwdriver, a lever element or the like. In this way, a release force can be applied to the securing element 24 using only an aid, which exceeds the closing force of the locking lever 24, supported on the support surface 20.2, in order to thus release the engagement of the securing element 24 in the receiving area 12 of the frame unit 10.

In the Fig. 7c-d Cross-sectional views of the sixth embodiment are shown, in particular to illustrate the functionality of the securing element 24. In particular, the Fig. 7c and 7d the attachment or interlocking of the securing element 24 to the cover unit 20 so that a captive connection is ensured.

The securing element 24 is inserted along the bearing grooves 24.1 and the bearing elements 20.1 into the cover unit 20 or into the receiving opening 20.3 of the cover unit 20.

The locking lever 24.2 slides according to Fig. 7c also along the bearing element 20.1. The locking lever 24.2 can be elastically deformed and slide off the loss prevention device 20.4 of the bearing element 20.1 in such a way that the locking lever 24.2 can snap over and the locking lever 24.2 slides over the loss prevention device 20.4, in the form of a bead or bulge of the bearing element 20.1.

In this way, according to Fig. 7d the securing element 24 can be locked onto the cover unit 20. A captive connection or interlock between the cover unit 20 and the securing element 24 can be provided.

Furthermore, the top of the securing element 24 can be designed in such a way that the sliding connection between the bearing elements 20.1 and the bearing grooves 24.1 is protected from contamination. The receiving opening 20.3, which is preferably at least partially funnel-shaped downwards, allows dirt and waste to fall through. Blocking of the securing element 24 is thus essentially avoided.

In summary, the present invention allows the provision of a gutter system 1 with a simplified and cost-effective structure, whereby a safe and quiet reception of the cover or grate unit 20 along the frame unit 10 is ensured. In particular, a dampened and secured or theft-proof reception of the cover unit 20 on the frame unit 10 can be achieved.
