Description

Channel system, cover unit and safety element

description

The invention relates to a channel system with at least one frame unit, at least one cover unit and at least one securing element. The invention also relates to a cover unit and a securing element.

In conventional gutter systems for drainage, the cover or grate unit is connected or crossed with the frame unit. In this way, the grate or cover unit is to be secured in the frame unit from 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 manufacture of such cast grates. Furthermore, the frame unit or the channel wall itself must be modified and designed using additional geometries in such a way that it is possible to intervene in the wall.

It is the object of the present invention to provide a gutter system which is simple and inexpensive to manufacture, enables an optimized grate or cover connection with different types of frame units, ensures simple assembly on site and at the same time provides simple maintenance and theft protection. A further object of the invention is to specify a cover unit and a securing element, in particular for such a channel system.

This object is achieved with a view to the gutter system by the subject matter of claim 1, with a view to the cover unit by claim 12 and with a view to the securing element by claim 13. Preferred embodiments are specified in the dependent claims. According to the invention, a channel system with at least one frame unit, at least one cover unit and at least one securing element is provided, the frame unit having at least one receiving area for the arrangement of the cover unit, and the securing element for engagement, in particular for force-fitting and / or form-fitting interlocked engagement, is designed in the cover unit and for releasable engagement in the receiving area, so that an interleaving of the cover unit in the receiving area of the frame unit can be provided.

The invention is based on the idea of providing a securing element which can be connected to the cover unit and enables a detachable connection to the frame unit. In particular, a captive connection of the securing element with the cover unit should be possible, with a connection between the cover unit and the frame unit being releasable if necessary by means of the securing element.

In this way, the cover unit can be connected or latched to the frame unit in a secure and simple manner. Furthermore, protection against theft can be achieved at the same time.

The frame unit can preferably be designed symmetrically, so that receiving areas are formed on the frame unit on both sides in the longitudinal direction of the channel system. The securing element is provided for convenient engagement in the receiving area.

Since the at least one securing element only engages in sections in the receiving area of the frame unit, frame units of various designs can be used in combination with the securing element or the cover unit for the gutter system. In particular, there is no need for a continuous, continuous receiving area along the frame unit.

According to a preferred embodiment, the securing element is elastically and / or plastically deformable in such a way that the engagement of the securing element in the at least one receiving area can be released if necessary, in particular by at least partial deformation of the securing element. A simple, expedient releasability of the securing element or the cover unit when connected to the frame unit can thus be ensured.

According to a further embodiment, the at least one receiving area of the frame unit is designed as an undercut.

In this way, the securing element can expediently engage in the frame unit in order to ensure a non-positive and / or positive connection, which can be detached if necessary, between the cover unit and the frame unit.

According to a preferred embodiment, the securing element has a release area for engagement, in particular for engagement by means of a screwdriver, a lever element or the like, in order to apply a release force to the securing element for elastic and / or plastic deformation of the securing element (30) if necessary.

Thus, the at least one securing element of the channel system can preferably only be operated with auxiliary means in order to release the engagement in the frame unit or the receiving area, and thus the connection between the frame unit and the cover unit.

In one embodiment, the securing element has a locking lever, the locking lever being supported against the cover unit and applying a closing force for non-positive and / or positive engagement of the securing element in the receiving area.

Since in particular the closing lever of the securing element is elastically and / or plastically deformable, a releasable connection between the cover unit and the frame unit can be provided in an expedient form with a predeterminable closing force.

According to a further embodiment, the cover unit has at least one receiving opening for receiving and guiding the at least one securing element. Thus, the at least one securing element can be received in the at least one receiving opening of the cover unit, preferably in an interleaved manner. Furthermore, a guide is provided through the cover unit along the desired direction of movement of the securing element in order to provide a detachable connection between the cover unit and the frame unit.

According to a further embodiment it is provided that the at least one receiving opening has at least one bearing element and the securing element has at least one correspondingly configured bearing groove for receiving and guiding the securing element.

Alternatively, the bearing groove can be formed along the receiving opening of the cover unit, the bearing element being formed along the securing element.

In this way, a connection or mounting and guidance can be provided between the securing element and the cover unit. In particular, the securing element and the cover unit engage with one another.

Furthermore, the receiving opening can have two bearing elements and the securing element can have correspondingly two bearing grooves, the bearing elements being formed on opposite side surfaces of the receiving opening of the cover unit. In this way, support and guidance of the securing element on both sides or on both sides can be provided in order to ensure reliable functionality.

According to one embodiment, the bearing element has a securing device at a longitudinal end, in particular in the direction of a central area of the channel system, so that the securing element and the cover unit can be connected in a force-locking and / or form-locking manner to provide a captive connection.

Thus, the securing element on the frame unit is interlocked in a force-locking and / or form-locking manner and is appropriately secured after an initial connection. For this purpose, the protection against loss can be provided along the bearing element as an additional latching lug or the like. The locking lever can be designed in such a way that the locking lever slides along the bearing element when the connection is established between the cover unit and the securing element and overcomes the anti-loss device by elastic deformation. The securing element can thus be secured or latched on the cover unit.

In a preferred embodiment, the at least one bearing element is nose-shaped. For example, a non-positive and / or positive engagement between the bearing element and the correspondingly configured bearing groove is available to provide an expedient receiving and guiding of the securing element.

In a further embodiment, the at least one receiving opening has a support surface for supporting the locking lever, so that a locking force can be exerted on the securing element by the locking lever.

According to a further embodiment, the support surface is configured with a curve at least in sections so that a release force to be applied to overcome the closing force of the closing lever is reduced at least in sections along the support surface or can be adjusted based on the configuration of the curve.

In particular, the at least section-wise rounding of the support surface can be configured in such a way that a release force does not increase over the support surface, does not exceed a threshold value or is reduced.

In a preferred embodiment it is provided that the locking lever has at least one locking lug for engaging in and / or behind the anti-loss device.

A non-positive and / or positive connection between the securing element and the cover unit can thus be provided.

According to one embodiment, the at least one securing element is designed in one piece and / or the at least one cover unit is in one piece designed. Preferably, the cover unit and the securing element can each be designed in one piece.

A reliable, stable and expedient entanglement or connection between the cover unit and the securing element can thus be provided.

In a secondary aspect of the invention, a cover unit is provided for use for a gutter system according to the invention, the cover unit having at least one receiving opening for receiving and guiding at least one securing element.

In a further secondary aspect of the invention, a securing element is provided for use with a gutter system according to the invention and / or a cover unit according to the invention.

In particular, the cover unit and the securing element can be used with any type of frame unit which at least on one side has a receiving area or the like for engagement by the securing element.

Universal use and a simple connection or securing of the cover unit to a frame unit can thus be provided.

The invention is explained in detail below with reference to the accompanying drawings.

They show schematically:

2a shows a plan view of the exemplary embodiment according to FIG. 1; FIG. 2b is a perspective view of a frame unit and the cover unit according to the exemplary embodiment according to FIG. 1; FIG.

3a-b show cross-sectional views of the exemplary embodiment according to FIG. 1, in particular to illustrate the functionality of the securing element; and

FIG. 4 shows a further cross-sectional view of the exemplary embodiment according to FIG. 1.

1 shows a cross-sectional view of an exemplary embodiment of a gutter system 1 with a cover unit 20 and a securing element 30.

The frame unit 10 is designed with a receiving area 12 for mounting 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 22 for mounting and receiving the securing element 30. Essentially, the receiving opening 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 22 from above can fall through the cover or grate unit.

In addition, the receiving opening 22 is formed with a support surface 24 in a central region of the cover unit 20 or of the channel system 1. The support surface 24 runs essentially in the 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 26. According to FIG. 1, the bearing element 26 extends longitudinally and transversely to the longitudinal direction of the channel system 1. In particular, the bearing element 26 can be designed to be slightly inclined with respect to the horizontal.

The bearing element 26 can have an anti-loss device 26.1 at one end, in particular in the direction of the central region of the channel system 1. The Loss protection 26.1 can be designed as a bulge or bulge along the bearing element 26. A force-fit and / or form-fit connection between the cover unit 20 and the securing element 30 is thus available. Captive entanglement is ensured.

The securing element 30 is inserted in the cover or grate unit 20 according to FIG. 1 and engages with a first end in a non-positive and / or positive manner in the receiving area 12 of the frame unit 10. Since the securing element 30 is configured with a phase along its underside at this first end, the securing element 30 can be locked into the receiving area 12 of the frame unit 10 in a simplified manner.

The securing element 30 is designed with at least one bearing groove 36, which is designed to correspond to the bearing element 26 of the receiving opening 22 of the cover unit 20. The bearing element 26 can thus engage in the bearing groove 36 in a force-fitting and / or form-fitting manner. Storage and guidance of the securing element 30 through the cover unit 20 is available.

Furthermore, the securing element 30 has a locking lever 34 at a second end, which is arranged in the central region of the channel system 1. The closing lever 34 is elastically and / or plastically deformable. In particular, the closing lever 34 is provided in such a way that it can be supported against the support surface 24 in order to apply a closing force to the securing element 30 and thus to ensure that it engages or engages in the receiving opening 12 of the frame unit 10.

The securing element 30 can be understood as a spring-loaded securing element 30 with a view to the preferably elastically deformable closing lever 34.

Furthermore, the securing element 30 has a release region 32 which is provided 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 30 exclusively with the aid of an aid, which the closing force of the closing lever 34, supported on the support surface 24, exceeds, in order to thus release the engagement of the securing element 30 in the receiving area 12 of the frame unit 10.

2a shows a top view of the exemplary embodiment according to FIG. 1. FIG. 2b shows a perspective view of a frame unit 10 and the cover unit 20 according to the exemplary embodiment according to FIG. 1.

According to FIG. 2a, the release region 32 is formed centrally in the transverse direction of the securing element 30. Furthermore, the securing element 30 can be designed in such a way that it only partially closes the receiving opening 22.

In particular, the top of the securing element 30 can be designed in such a way that the sliding connection between the bearing elements 26 and the bearing grooves 36 is protected from contamination. The receiving opening 22, which is preferably at least partially funnel-shaped downwards, enables dirt and waste to fall through. Blocking of the securing element 30 is thus essentially avoided.

According to FIG. 2b, a bearing element 26 is provided on both sides of the receiving opening 22. The bearing elements 26 are each formed in the shape of a nose and thus provide a receiving function, a guiding function and a sliding function for the securing element 30.

Furthermore, it can be seen from Fig. 2b that the lid or

Grate unit 20 extends up to the receiving area 12 of the frame unit 10, the receiving area 12 being partially undercut.

FIGS. 3a-b show cross-sectional views of the exemplary embodiment according to FIG. 1, in particular to illustrate the functionality of the securing element. In particular, FIGS. 3a and 3b show the attachment or interlacing of the securing element 30 on the cover unit 20, so that a captive connection is ensured.

The securing element 30 is pushed along the bearing grooves 36 and the bearing elements 26 into the cover unit 20 or into the receiving opening 22 of the cover unit 20. The locking lever 34 also slides along the bearing element 26 according to FIG. 3 a. The locking lever 34 can be elastically deformed and slid on the locking lever 26.1 of the bearing element 26 in such a way that the locking lever can snap over and the locking lever 34 slides over the locking device 26.1 in the form of a bulge or bulge of the bearing element 26.

In particular, the locking lever 34 can have a latching lug 34.1 which is designed to engage behind and / or in the anti-loss device 26.1 of the bearing element 26.

In this way, according to FIG. 3b, the securing element 30 can be latched onto the cover unit 20. A captive connection or entanglement between the cover unit 20 and the securing element 30 can be provided.

FIG. 4 shows a further cross-sectional view of the exemplary embodiment according to FIG. 1. In particular, the design of the release area 32 of the closing element 30 is shown in cross-section.

According to FIG. 4, only a lever-shaped aid such as a screwdriver can be introduced into the release area in a targeted manner from an upper side of the closing element. In particular, by supporting the auxiliary means on the frame unit 10, a leverage effect can be applied to the securing element 30, so that a release force which is greater than the closing force of the closing lever 34, which is supported, can be applied. In this way, the securing element 30 can be displaced along the bearing grooves 36 and the bearing elements 26 in the central direction of the channel system 1 and engagement of the securing element 30 in the undercut receiving area 12 of the frame unit 10 can be released.

In summary, the present invention makes it possible to provide a channel system 1 with a simplified and cost-effective structure, with a safe or secure reception of the cover or grate unit 20 along the frame unit 10 being ensured. In particular, the cover unit 20 or the securing element 30 can be used with any frame units 10 which have at least one receiving area 12. Furthermore, a simple detachment of the cover unit 20 by specialist personnel is only possible with aids, so that an expedient use in everyday life and an anti-theft device is guaranteed. In particular, based on the design of the safety element 30 with the release area 32, the release function is at least partially hidden in the interior of the channel system 1 by applying force against the closing force of the closing lever 34.
