Description

Technical Field

[0001] The present invention relates to a drainage ditch system, which has at least one frame unit, at least one cover unit and at least one first damping element. Background Art

[0002] In common drainage ditch systems for drainage, the cover unit or grating unit is connected or interconnected with the frame unit. In this way, the grating unit or cover unit in the frame unit should be protected from falling off and / or lifting.

[0003] However, especially for thick-walled drainage ditch systems, a large grating width is required for this purpose, so that increased cost consumption is needed in manufacturing such cast gratings. In addition, the frame unit or the drainage ditch wall itself must be modified and designed according to additional geometries so that it is feasible to engage it into the wall. In addition, directly placing the cast grating or cast cover on the frame unit will cause a non-static grating position. Summary of the Invention

[0004] The object of the present invention is to provide a drainage ditch system that can be manufactured simply and cost-effectively, provides optimized grating or cover support, enables simple on-site assembly and at the same time provides simple maintenance.

[0005] The above object is achieved by the drainage ditch system according to the present invention. Preferred embodiments are described in the present invention.

[0006] The present invention relates to a drainage ditch system, which has 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 setting or accommodating the cover unit, and the receiving area of the frame unit is constituted by at least three side walls, preferably by five side walls. The first damping element is arranged between the frame unit and the cover unit, so that the cover unit is accommodated in the frame unit or at least one receiving area of the frame unit in a vibration-damping support manner in at least three spatial directions, preferably in at least five spatial directions.

[0007] The present invention is based on the following basic concept: The frame unit has an area for positioning and accommodating, and this area is designed by means of the first damping element so that the inserted cover unit or grating unit is supported in a vibration-damping manner in at least three spatial directions during its use according to the application. Therefore, it is also possible to provide a static grating position or cover position for, for example, the cast iron cover unit and frame unit of the drainage ditch system.

[0008] According to the present invention, at least one receiving area can be constituted by at least three side walls. The cover unit can especially be inserted into the receiving area of the frame unit. Therefore, the cover unit can especially be placed on the first side wall, the second side wall or the third side wall.

[0009] Preferably, at least three side walls of at least one receiving area are configured such that the cover unit is surrounded on three sides.

[0010] Particularly preferably, at least one receiving area having five side walls can be configured such that the cover unit can be introduced into the receiving area via one side and is surrounded on five sides by the side walls of the receiving area.

[0011] Furthermore, a first damping element is formed between the frame unit and the cover unit such that the cover unit is supported in a damped manner in the frame unit in at least three spatial directions.

[0012] Preferably, the cover unit can be supported or received in a damped manner in at least one receiving area in four or five spatial directions.

[0013] Therefore, when two mutually opposed receiving areas of the frame unit are formed for receiving or supporting the cover unit on both sides, it is obtained in total that the cover unit is supported or received in a damped manner in at least four spatial directions, preferably in all six spatial directions.

[0014] In a particularly preferred manner, it is proposed that, in the sense of the orientation or alignment according to the application, the cover unit is supported in a damped manner in the frame unit both upwards in the vertical direction and on both sides in the longitudinal direction of the drain system. Thereby, damping along three sides or spatial directions is obtained, and in particular, a movement lock of the cover unit in the longitudinal direction of the drain system is obtained.

[0015] When forming a drain system with a circular cover unit, it is also feasible to provide a damped support for the cover unit by means of a single receiving area of the frame unit.

[0016] In the sense of the present invention, at least one first damping element is formed in the receiving area of the frame unit in order to provide a damped support for the cover unit in a plurality of spatial directions. Thus, a stationary grate position or cover position can be achieved for the drain system.

[0017] According to one embodiment, the receiving area of the frame unit having at least three side walls is configured as an undercut such that the cover unit is at least partially surrounded by the frame unit along at least three sides.

[0018] Therefore, the cover unit can be inserted into the receiving area of the frame unit configured in the form of an undercut, wherein the dropping out or lifting of the cover unit is substantially avoided by the geometry of the undercut. More precisely, it is preferably proposed that the receiving area allows the cover unit to be removed only in the direction opposite to the insertion of the cover unit.

[0019] According to the configuration of at least one receiving area of the frame unit having at least three side walls as an undercut, it is possible to provide, in particular, a locking function, a movement locking function and a damping function for the cover unit.

[0020] Thus, a safe and proper arrangement of the cover unit in the frame unit can be achieved.

[0021] In another embodiment, the cover unit has at least one engaging element for engaging into the receiving area of the frame unit. The engaging element can in particular be configured as a raised projection at the frame unit. Thus, the cover unit can be safely inserted and positioned in the corresponding receiving area of the frame unit.

[0022] According to a preferred embodiment, the cover unit is configured in combination with at least one lock element designed to be movable such that the movable lock element is movable for at least temporarily engaging into the receiving area of the frame unit. The lock element can in particular be movable translationally or rotatably by at least 90°.

[0023] In this sense, the cover unit can have a movable lock element and a non-movable engaging element.

[0024] The lock element can for example be configured as an elastically supported connecting element or a helically fixable connecting element for engaging from below or from behind into the receiving area or a receiving area configured in the form of an undercut. At least one lock element of the cover unit can in particular be configured as a slide bolt, a spring catch in the sense of a door lock principle, a window latch or the like.

[0025] According to one embodiment, at least one first damping element is arranged along at least three of the side walls of the receiving area of the frame unit or as an attachment for being arranged at the cover unit, in particular at least one engaging element.

[0026] Thus, it is possible to provide a damping support or accommodation of the cover unit in at least one receiving area in at least three spatial directions, preferably five spatial directions, in such a way that the side walls can be configured with the first damping element.

[0027] Alternatively, at least one first damping element is arranged along the cover unit. In particular, at least one engaging element of the cover unit can be configured with the first damping element such that damping can be provided between the frame unit and the cover unit or the grate unit in at least three spatial directions, preferably five spatial directions.

[0028] In one embodiment, at least one first damping element is designed as a surface coating or as at least one insert for positioning along the receiving area.

[0029] Thus, the first damping element can in particular be formed or applied in the form of a surface coating along three side walls in the receiving area of the frame unit. Alternatively, it is feasible to design the first damping element as an insert, which is introduced into the receiving area along the side walls at least temporarily.

[0030] Alternatively, at least one engaging element of the cover unit can have a surface coating or attachment for providing the first damping element in the sense of the present invention. Additionally, it is conceivable that at least one engaging element is made of a polymer, for example, and serves as the first damping element as a whole.

[0031] In one embodiment, at least one second damping element is provided along the side of the cover unit opposite to the frame unit, preferably at least one second damping element is provided on the side of the frame unit opposite to the provided first damping element in the assembled state of the drainage system.

[0032] In particular, the second damping element can be applied as a surface coating or surface layer on the cover unit, so that one of the sides opposite to the frame unit is damped. Thus, additional damping along the cover unit in the spatial direction by means of the second damping element is available.

[0033] It is also conceivable to damp both sides of the cover unit by means of the second damping element.

[0034] According to a preferred embodiment, the first damping element and / or the second damping element are arranged such that the cover unit is received in the frame unit in a damped manner in the longitudinal direction of the drainage system at the side walls of the receiving area.

[0035] In this way, in particular, the movement of the cover unit in the longitudinal direction of the drainage system can be suppressed and / or damped. For example, damping in the upward direction in the vertical direction can be provided as damping in at least the third spatial direction.

[0036] According to another preferred embodiment, the first damping element and / or the second damping element are made of a plastically deformable and / or elastically deformable material, in particular a polymer.

[0037] Particularly advantageously, the damping element can have a plurality of recesses, and the corresponding thickened portions of the cover unit engage into the recesses, and thus a secure fit of the damping element at the cover unit can be achieved. Additionally, at least one damping element can have undercuts at its upper leg and / or lower leg to additionally improve the fastening on the thickened portion of the cover unit.

[0038] The cover unit and the frame unit can be made of metal, in particular cast iron, or can be made of similar suitable materials for forming a drainage system for drainage.

[0039] Thus, the plastically deformable and / or elastically deformable material of at least one first and / or second damping element can provide suitable damping between the frame unit and the cover unit, especially for achieving a stationary grille position or cover position.

[0040] According to another embodiment, the frame unit has at least one movement locking device by means of an insert as the first damping element, wherein the insert engages into the cover unit such that movement locking is provided in the longitudinal direction of the drainage system.

[0041] At least one movement locking device can be configured to cooperate or engage with at least one engaging element of the cover unit.

[0042] Alternatively, the extension of at least one receiving area, preferably configured in the form of an undercut, in the direction of the longitudinal axis of the drainage system can be provided with movement locking elements, such as in the form of support ribs or intermediate ribs, etc. Thus, different sections of the longitudinally extending receiving area of the frame unit can each be configured with five side walls.

[0043] Suitable movement locking of the cover unit or the grille unit can be provided.

[0044] In one embodiment, the frame unit is configured symmetrically with respect to the longitudinal axis of the drainage system.

[0045] Thus, the cover unit can be used interchangeably with the frame unit, wherein the cover unit can be designed asymmetrically. Preferably, there is no direction-related common engagement of the cover unit and the frame unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In Figure 1 a cross-sectional view of a drainage system 1 according to a first embodiment is shown. The drainage system 1 has a frame unit 10 and a cover unit 20.

[0056] The frame unit 10 is provided on both sides with receiving areas 12 formed in the form of undercuts. The receiving areas 12 are formed by at least three side walls according to the first, second and third side walls 12.1; 12.2; 12.3.

[0057] Along these three side walls 12.1; 12.2; 12.3, a first damping element 14 is provided. The first damping element 14 can be designed as a surface coating or insert 16 (see Figure 2 ).

[0058] According to Figure 1 , the cover unit or grating unit 20 has at least one engaging element 22, which is designed to engage into the receiving area 12 formed in the form of an undercut of the frame unit 10. Here, the first damping element 14 is formed between the frame unit 10 and the cover unit 20.

[0059] The cover unit 20 can be provided with at least one engaging element 22 on one or both sides. According to Figure 1 , a configuration of the side where the engaging element 22 is provided at the cover unit 20 is shown. In this sense, the cover unit 20 can be configured asymmetrically.

[0060] Furthermore, according to Figure 1 , a force-fit and / or form-fit connection between the cover unit 20 and the frame unit 10 is provided. For this purpose, the frame unit 10 has a first tensioning element 18, which can be configured as a V-shaped groove symmetric along the longitudinal axis of the drainage system 1. Thus, an alternating or direction-independent setting of the cover unit 20 at the frame unit 10 is possible.

[0061] The cover unit 20 has at least one locking element 24, in particular in the form of a hook with a V-shaped projection for engaging into one of the first tensioning elements 18. According to Figure 1 , at least one locking element 24 is provided on the side of the cover unit 20 opposite to the engaging element 22. Thus, a releasable force-fit and / or form-fit connection can be suitably provided between the cover unit 20 and the frame unit 10.

[0062] By following Figure 1 The configuration with the engagement element 22 and at least one locking element 24 on opposite sides can bring about a force-fitting and / or form-fitting connection between the frame unit 10 and the cover unit 20 in the sense of an at least partially rotational displacement of the cover unit 20 .

[0063] exist Figure 2 The following table shows the Figure 1 A perspective view of an insert 16 for use with a gutter system.

[0064] 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 a vibration-damping side wall 12.1; 12.2; 12.3; 12.4; 12.5 in different spatial directions, at least in three spatial directions, or serve as a vibration-damping device for a center rib along the receiving area 12.

[0065] Furthermore, any desired arrangement of a plurality of insert parts 16 along the receiving area 12 is possible, in particular depending on the positioning of the locking elements 24 along the cover unit or the grate unit 20 .

[0066] exist Figures 3a to 3d 1 shows different views of a second exemplary embodiment of a gutter system 1 .

[0067] Especially in Figure 3a 2 illustrates a cover unit having two locking 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 .

[0068] The first damping element 14 is therefore designed to damp vibrations of the cover unit 20 along a section of the receiving area 12 .

[0069] In particular, vibration damping can be provided in the longitudinal direction of the gutter system 1 relative to 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. An intermediate rib can be understood here as the fourth or fifth side wall 12.4; 12.5. With such intermediate ribs, a vibration-damping locking of the cover unit 20 against sliding in the longitudinal direction of the gutter system 1 can also be provided.

[0070] exist Figure 3b , the engagement element 22 is shown positioned in the receiving area 12 of the gutter unit 10, which is at least partially formed in the form of an undercut. In this way, the cover unit 20 cannot be removed from the frame unit 10 only in the vertical direction. The engagement element 22 and the receiving area 12 are detachably interconnected.

[0071] exist Figure 3cThe vibration-damping support of the cover unit 20 or the engaging element 22 in the receiving area 12 of the frame unit 10 is shown.

[0072] In particular, the engaging element 22 is surrounded by the first vibration-damping element 14, or the first vibration-damping element 14 is arranged on the engaging element 22. In this way, vibration damping can be provided especially 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.

[0073] In Figure 3d the vibration-damping support of the engaging element 22 in the receiving area 12 divided by the intermediate rib is shown.

[0074] The first vibration-damping element 14 especially surrounds the engaging element 22 of the cover unit 20, so that a movement lock is provided in a vibration-damping form in the longitudinal direction of the drainage system 1.

[0075] In Figures 4a to 4b different views of the third embodiment of the drainage system 1 are shown. In particular, the design of the locking element 24 is illustrated in the sense of the embodiment according to Figure 1 .

[0076] The locking element 24 engages in a force-fitting and / or form-fitting manner in the undercut receiving area 12 of the frame unit 10. In addition, the locking element 24 engages by means of a V-shaped projection in the first tensioning element 18, which is designed below the receiving area for tensioning the locking element 24 in combination with the cover unit or the grating unit 20. In this way, the interconnection of the cover unit 20 on the frame unit 10 can be provided.

[0077] At least one first tensioning element 18 can especially be arranged at the frame unit 10 and be injected or cast below the receiving area 12.

[0078] The frame unit 10 with the receiving area 12 on both sides can preferably be configured symmetrically, so that the cover unit 20 with the engaging element 22 and the locking element 24 can be inserted on both sides or alternately or independently of the direction.

[0079] In Figure 5 a cross-section of the fourth embodiment of the drainage system 1 is shown, in particular a view of the locking element 24. In Figure 6 different additional views of the fourth embodiment are illustrated.

[0080] According to Figure 5 and Figure 6 , the locking element 24 is configured as a rotatably movable locking element 24.

[0081] The locking element 24 is especially rotatably movably received in the receiving opening 20.3 of the cover unit 20 or is clamped on the rotation axis of the cover unit 20.

[0082] The axis of rotation of the locking element 24 is oriented in the longitudinal direction of the drainage system 1 at the cover unit 20 and is arranged directly adjacent to the receiving area 12 at the cover unit 20. Thus, during the locking rotation, the locking element 24 can engage or screw into the receiving area 12 formed in the form of an undercut in the frame unit 12.

[0083] At the opposite ends of the locking element 24, there are formed latching projections according to Figure 6 which protrude towards the middle region of the drainage system 1 in the locked state.

[0084] The latching projections of the locking element 24 can engage with the first tensioning element 18 for locking or interconnecting, and the first tensioning element is formed at the cover unit or grating unit 20 in the sense of a projection.

[0085] In this way, the locking element 24 can be locked in the stop position or locking position at the tensioning element 18, wherein the locking element 24 engages in the undercut receiving area 12 on the opposite sides of the axis of rotation. Thus, the cover unit or grating unit 20 and the frame unit 10 can be suitably interconnected with each other according to the locking element 24 according to Figure 5 and Figure 6 respectively.

[0086] Figures 7a to 7d Different views showing the fifth embodiment of the drainage system 1, in particular a view of the locking element 24.

[0087] According to Figure 7a , a release area 24.3 is formed centrally in the transverse direction of the locking element 24. In addition, the locking element 24 can be configured such that the locking element only partially closes the receiving opening 20.3. A plurality of locking elements 24 are provided spaced apart from each other in the longitudinal direction of the drainage system 1.

[0088] In Figure 7b a cross-sectional view of the fifth embodiment is shown.

[0089] The frame unit 10 is formed with a receiving area 12 for supporting and receiving the cover unit 20. The receiving area 12 is at least partially formed as an undercut or in the form of an undercut.

[0090] The cover unit 20 has a receiving opening 20.3 for supporting and receiving the locking element 24. The receiving opening 20.3 can be increased at least in part from top to bottom along the orientation of the cover unit 20 in common use. In this way, waste or dirt that can enter the receiving opening 20.3 from above can fall through the cover unit or grating unit 20.

[0091] Furthermore, the receiving opening 20.3 is formed in an intermediate region of the cover unit 20 or the drain system 1 having a support surface 20.2. The support surface 20.2 extends substantially in the vertical direction and has a radius or rounding at least at its lower end.

[0092] Furthermore, the frame unit 20 has at least one support element 20.1. According to Figure 1 , the support element 20.1 extends elongately and transversely to the longitudinal direction of the drain system 1. The support element 20.1 can in particular be configured to be slightly inclined relative to the horizontal line.

[0093] The support element 20.1 can have a anti-loss device 20.4 at one end, in particular towards the intermediate region of the drain system 1. The anti-loss device 20.4 can be configured as a raised portion or arch along the support element 20.1. Thus, a force-fit and / or form-fit connection of the cover unit 20 with the locking element 24 is available. An interconnection that will not be lost is provided.

[0094] According to Figure 1 , the locking element 24 is inserted into the cover unit or the grating unit 20 and engages in a force-fit and / or form-fit manner with the receiving region 12 of the frame unit 10 by means of its first end. By designing a stepped portion along the lower side of the locking element 24 at the first end, the locking element 24 can be latched into the receiving region 12 of the frame unit 10 in a simplified manner.

[0095] The locking element 24 is formed with at least one support groove 24.1, which is designed to correspond to the support element 20.1 of the receiving opening 20.3 of the cover unit 20. Thus, the support element 20.1 can engage in a force-fit and / or form-fit manner into the support groove 24.1 for sliding accommodation. The locking element 24 is available by the support and guidance of the cover unit 20.

[0096] Furthermore, the locking element 24 has a locking lever 24.2 at its second end, and the second end is arranged in the intermediate region of the drain system 1. The locking lever 24.2 is elastically deformable and / or plastically deformable. The locking lever 24.2 is in particular arranged such that the locking lever can be supported against the support surface 20.2 of the cover unit 20 in order to apply a locking force to the locking element 24 to ensure latching or engagement into the receiving opening 12 of the frame unit 10.

[0097] The locking element 24 can be understood as a spring-loaded locking element 24 from the perspective of a preferably elastically deformable locking lever 24.2.

[0098] In addition, the locking element 30 has a release area 24.3 which is designed to engage with, for example, a screwdriver, a lever element or the like. In this way, a release force can be applied to the locking element 24 only by means of an auxiliary mechanism, said release force exceeding the locking force of the locking lever 24 supported at the support surface 20.2, in order to thus release the engagement of the locking element 24 in the receiving area 12 of the frame unit 10.

[0099] In Figures 7c to 7d shows a cross-sectional view of the sixth embodiment, in particular for illustrating the functionality of the locking element 24. Figure 7c and Figure 7d In particular, the mounting or interconnection of the locking element 24 on the cover unit 20 is shown, such that a connection that cannot be lost is ensured.

[0100] The locking element 24 is pushed into the cover unit 20 or the receiving opening 20.3 of the cover unit 20 along the support groove 24.1 and the support element 20.1.

[0101] According to Figure 7c , the locking lever 24.2 also slides along the support element 20.1. At the anti-loss device 20.4 of the support element 20.1, the locking lever 24.2 can be elastically deformed and slide, such that the latching of the locking lever 24.2 is feasible and the locking lever 24.2 slides over the anti-loss device 20.4 in the form of a bulge or arch.

[0102] According to Figure 7d , the locking element 24 can be locked at the cover unit 20 in the manner described. A connection or interconnection that cannot be lost can be provided between the cover unit 20 and the locking element 24.

[0103] In addition, the upper side of the locking element 24 can be designed such that the sliding connection between the support element 20.1 and the support groove 24.1 is protected from contamination. Preferably, the receiving opening 20.3 which is at least partially funnel-shaped downwards enables dirt and waste to fall through. Thus, blockage of the locking element 24 is substantially avoided.

[0104] In summary, the invention allows a drainage system 1 with a simplified and cost-effective construction to be provided, in which a safe and stationary accommodation of the cover unit or grating unit 20 along the frame unit 10 is ensured. In particular, it is possible to accommodate the cover unit 20 at the frame unit 10 in a vibration-damping and safe or anti-theft manner.
