Description

The invention relates to a device for supporting a gutter and/or support structure and for adjusting a height of a gutter and/or support structure, having the features of the preamble of claim 1. A device having the features of the preamble of claim 1 is known, for example, from DE 20 2006 009 404 U1 known. The invention further relates to a system comprising a device according to the invention and a gutter and/or support structure, and a method for supporting a gutter and/or support structure and/or for adjusting a height of a gutter and/or support structure.

the DE 20 2006 009 404 U1 describes a height-adjustable drainage channel for terraces, balconies and the like. The height-adjustable drainage channel can be adjusted in height relative to the ground by means of a support device. The support device comprises threaded shanks provided with feet, which interact with threaded receptacles arranged on the gutter in such a way that the level of the gutter is adjusted by rotating the shank in the threaded receptacle. According to the teaching of DE 20 2006 009 404 U1 the channel has punched holes in the outer edge area of the floor to accommodate the threaded mounts. Every Threaded mount is designed as a sleeve with a continuous threaded bore for the threaded shank and has an external thread in the upper area. The diameter of the sleeve is slightly smaller than the diameter of the punched hole in the bottom of the channel and the lower area of the sleeve has an area that overlaps the punched hole. To fix the sleeve, a lock nut is placed in the channel trough, which in particular presses or clamps the sleeve and here the overlapping area from below against the channel bottom. The Revelation of DE 20 2006 009 404 U1 attempts to overcome the disadvantages of the prior art, according to which the realization of a height-adjustable support device requires a complex substructure on the channel and a height-adjustable support device is generally complex to assemble.

Against this background, the object of the present invention is to specify a further improved device for supporting a gutter and/or support structure and for adjusting a height of a gutter and/or support structure. One focus is on a further simplified assembly of height-adjustable gutters and/or support structures as well as stable support and simple height adjustment.

According to the invention, the object is achieved by a device for supporting a gutter and/or support structure and for adjusting a height of a gutter and/or support structure according to claim 1 . With regard to the system, this object is achieved by the subject matter of claim 12. With regard to the method for supporting a gutter and/or support structure and/or for adjusting a height of a gutter and/or support structure, this object is achieved by the subject matter of claim 17.

The invention is based on the idea of specifying a device for supporting a gutter and/or support structure and for adjusting a height of a gutter and/or support structure. The device comprises i) a threaded rod for passing through a through-opening of a fastening element, the threaded rod being connected through its external thread to an internal thread of the fastening element or to an internal thread of a positive-locking element, in particular a nut, of the Fastening element can be connected and wherein the threaded rod has a foot at a first end. The device also comprises ii) the fastening element for fastening to the threaded rod and for fastening to the gutter and/or support structure,
wherein the fastening element has the through-opening for receiving the threaded rod and wherein the fastening element for connection to the threaded rod comprises the internal thread or a receptacle for the positive-locking element, in particular the nut. The device is characterized in that the fastening element comprises at least one groove for connection to the gutter and/or support structure, the at least one groove being arranged perpendicularly to the longitudinal axis of the through-opening. It is advantageous that the fastening element can be pushed at least partially into the channel and/or support structure by a lateral receptacle of the channel and/or support structure. In other words, it is possible to insert the fastening element at least partially from the side. This makes assembly of the device particularly simple. In addition, a complex substructure on the channel is not required. Another advantage is that the height can be continuously adjusted.

In the mounted state, the at least one groove is arranged essentially horizontally and the longitudinal axis of the through-opening extends essentially vertically.

The fastening element is preferably at least partially pushed into the channel and/or support structure by a lateral receptacle of the channel and/or support structure. A metal sheet or section of the bottom of the channel and/or support structure is inserted into the at least one groove for connection to the channel and/or support structure.

In one embodiment, the fastening element for connection to the threaded rod comprises the internal thread. In this embodiment, the internal thread of the fastening element is preferably arranged in the through-opening for receiving the threaded rod.

More preferred is an embodiment in which the fastening element for connection to the threaded rod comprises the receptacle for the positive-locking element. The receptacle for the positive-locking element is preferably in the entry area of the through-opening for receiving the threaded rod arranged. In other words, the receptacle for the positive-locking element is preferably formed on a surface of the fastening element symmetrically and centrally around the longitudinal axis of the through-opening.

The receptacle for the form-fitting element is particularly preferably designed conically. By clamping it in the conical mount, a secure fit of the form-fitting element is ensured during assembly. This further simplifies assembly. Conical means that the walls delimiting the receptacle, based on the longitudinal axis of the through-opening, are inclined outwards, preferably by 2° to 20°, more preferably 5° to 15°.

The positive-locking element is preferably a nut and the receptacle for the positive-locking element is a receptacle for a nut. Preferably, the nut is a hex nut and the nut receptacle is a hex nut receptacle. The form-fitting element can also be a square disc with an internal thread. Other screw elements with a form-fitting outer contour are possible.

The receptacle for the form-fitting element is preferably arranged on the surface of the fastening element in such a way that the receptacle is aligned with the center of the earth or with the foot of the threaded rod when it is mounted on the channel and/or support structure. In other words, the receptacle for the form-fitting element is located on the underside of the fastening element in the installed state.

In the installed state, the form-fitting element is arranged in a form-fitting manner in the receptacle and is held against twisting.

The at least one groove preferably has a thickness of 0.5 mm to 5 mm, more preferably 1.0 mm to 4 mm, even more preferably 1.25 mm to 3 mm. Correspondingly, for example, a metal sheet or section of the bottom of the channel and/or support structure with a thickness of 0.5 mm to 5 mm, more preferably 1 mm to 4 mm, even more preferably 1 mm to 2 mm, can be inserted into the at least one groove will. A metal sheet or section of the bottom of the channel and/or supporting structure with a thickness of eg about 1 mm or about 1.5 mm and additionally, preferably underneath, a reinforcing element, eg in the form of a metal sheet, can also be inserted into such a groove. It is advantageous that a secure fit when inserting the fastener also with different material thicknesses of the channel bottom and, if necessary, the reinforcement element is guaranteed.

The fastening element preferably extends along a longitudinal axis.

The at least one groove preferably extends along at least one longitudinal side of the fastening element.

The fastening element preferably comprises two longitudinal sides, the longitudinal sides preferably being essentially parallel to one another. The at least one groove preferably extends along both longitudinal sides of the fastening element. The at least one groove can be designed as two grooves or as a continuous groove that runs over both longitudinal sides of the fastening element.

The at least one groove preferably divides the fastening element into a first part (lower in the assembled state) and a second part (upper in the assembled state), the lower/first part and the upper/second part being connected by a web of the fastening element which preferably extends along the longitudinal axis of the fastening element and is optionally interrupted by the through-opening.

The height of the web preferably results from the thickness of the at least one groove and is preferably 0.5 mm to 5 mm, more preferably 1.0 mm to 4 mm, even more preferably 1.25 mm to 3 mm.

The at least one groove is preferably arranged in such a way that the first/lower part has a greater height than the second/upper part.

The first/lower part of the fastening element preferably includes the receptacle for the positive-locking element, preferably for the nut.

Preferably (only) the second/upper part of the fastening element can be pushed into the channel and/or support structure through a receptacle, preferably a lateral receptacle, of the channel and/or support structure. The side mount is preferably a horizontal mount (when assembled).

The fastening element can preferably be pushed at least partially along its longitudinal axis through the lateral receptacle of the channel and/or support structure into the channel and/or support structure.

The fastening element preferably has two essentially parallel longitudinal sides, a rear side perpendicular thereto and a semicircular front side. The at least partial insertion into the channel and/or support structure is preferably carried out with the semicircular front side first.

The at least one groove preferably extends over 50% to 99% of the circumference of the fastening element.

The through-opening of the fastening element preferably has a constriction for creating a thread blockage. The thread lock prevents the threaded rod from turning loose unintentionally.

At a second end, the threaded rod preferably has means for positively locking force transmission for rotating the threaded rod.

The means for the form-fitting force transmission are preferably designed in a form selected from a slot, cross slot, hexagon socket and external hexagon, with the means being particularly preferably designed in the form of a hexagon socket.

The advantage is that the height can be adjusted using a tool from above on the threaded rod. The height can therefore be adjusted when the channel and/or support structure is installed. This also simplifies assembly as the height can be adjusted after assembly.

The fastening element preferably contains plastic, preferably electrically non-conductive plastic. More preferably, the fastener consists essentially of plastic, preferably of electrically non-conductive plastic. Preferably, the fastener is electrically non-conductive. Such a fastener allows the gutter and/or support structure to be electrically isolated from the threaded rod with foot. This allows the use of different materials, such as galvanized steel and stainless steel, in the gutter and/or support structure and the threaded rod with foot.

The fastening element is preferably in one piece. Such a fastening element enables a particularly easy-to-install and firm connection between the fastening element and the channel and/or support structure.

The fastening element preferably has no external thread.

A fastener having an external thread and an internal thread may unintentionally loosen a threaded connection when, for example, the threaded rod is rotated to adjust a height of the gutter and/or support structure.

Preferably, the foot includes a footplate.

Preferably, the base plate is movably attached to the threaded rod, more preferably riveted.

The threaded rod is preferably rotatably mounted in the foot.

The invention is also based on the idea of specifying a system that includes devices according to the invention for supporting the gutter and/or support structure and for adjusting a height of the gutter and/or support structure, as well as a gutter and/or support structure with lateral receptacles for at least partial, preferably lateral , Sliding the fastening element into the channel and/or support structure in such a way that, in the assembled state, a metal sheet or section, preferably of the bottom, of the channel and/or support structure engages in the at least one groove of the fastening element.

The trough and/or support structure preferably has through-openings in the base of the trough or support structure for receiving the threaded rod. In one embodiment, the diameter of these through-openings corresponds to the diameter of the threaded rod, so that there is a form fit. In one embodiment, the diameter of these through-openings is larger than the diameter of the threaded rod, so that there is no positive locking.

The channel and/or support structure preferably has receptacles for the web of the fastening element in the base of the channel or support structure.

A receptacle in the channel or support structure preferably forms the lateral receptacle for at least partial, preferably lateral, insertion of the fastening element into the channel and/or support structure and the through-opening in the bottom of the channel or support structure for receiving the threaded rod and the receptacle in the bottom of the Channel or support structure for the web of the fastening element.

The system can be assembled or unassembled (in separate parts). In the assembled state, the system preferably comprises at least four devices according to the invention for supporting a gutter and/or support structure and for adjusting a height of the gutter and/or support structure, as well as the gutter and/or support structure with at least four lateral receptacles for at least partial, preferably lateral, insertion of the fastening elements and, if necessary, at least four through-openings for receiving the threaded rods in the bottom of the channel or support structure and, if necessary, at least four receptacles for the web of the fastening elements.

In the installed state, the fastening element is preferably connected in a form-fitting manner to the channel and/or support structure.

The term "positive connection" means that the cohesion of the fastening element and the channel and/or support structure is ensured by the shape of the parts without constantly acting forces (prestressing). This applies to the two-sided form fit, in which the cohesion acts in two axial directions, as well as to a one-sided form fit, in which the cohesion acts in a single axial direction. In contrast to the form-fitting connection, in the case of the force-fitting connection, the cohesion of the components is achieved by constantly acting (external) forces.

In the assembled state, the fastening element preferably electrically separates the threaded rod and the channel and/or support structure from one another.

In the assembled state, the channel and/or support structure are preferably not connected to the threaded rod via a component which has an external thread and an internal thread.

Preferably, the system includes a reinforcement member for reinforcing the gutter and/or support structure. The system preferably comprises at least two reinforcement elements for strengthening the channel and/or support structure.

The reinforcement element serves to reinforce the body of the gutter and/or the support structure. If the channel and/or support structure is loaded from above, the force is transferred via the lateral grating supports to the height-adjustable feet. Since these feet are not in a direct line to the introduction of force, a torque is generated here that bends the bottom of the channel and/or support structure inwards. The reinforcing element or stiffening profile prevents this effect, particularly if it is U-shaped. The reinforcement element preferably has a recess for receiving the fastening element. The fastening element connects the channel and/or support structure and the reinforcement element to one another by being pushed on.

The reinforcement element preferably comprises a metal sheet, which particularly preferably has a U-shape. The U-shaped configuration of the reinforcement element preferably enables a form-fit connection with a fastening element along the longitudinal sides of the fastening element.

Each reinforcement element preferably comprises at least two receptacles for at least partially pushing in or inserting one fastening element each. Preferably, the recordings are each for receiving a web of a fastening element. In other words, it is preferred that a fastening element can be pushed at least partially into the reinforcement element along its longitudinal axis through the receptacle of the reinforcement element. There are preferably two recordings per fastening element. It is particularly preferred that the two receptacles for at least partially pushing in or inserting a fastening element each are arranged at opposite ends of the reinforcement element. Preferably, the two receptacles for at least partially pushing in or inserting a fastening element each are arranged on the longitudinal axis of the reinforcement element.

Each reinforcement element comprises at least one through-opening, preferably two through-openings, each for receiving a threaded rod.

In one embodiment, the diameter of these through-openings corresponds to the diameter of the threaded rod, so that there is a form fit. In one embodiment, the diameter of these through-openings is larger than the diameter of the threaded rod, so that there is no positive locking. Preferably, one receptacle of the reinforcement element forms the receptacle for at least partially inserting a fastening element, in particular for the web of the fastening element, and the through-opening for receiving a threaded rod.

In the mounted state, both the reinforcement element and the channel and/or support structure extend essentially along their longitudinal axis in the horizontal direction. In the mounted state, the longitudinal axis of the reinforcement element preferably extends perpendicularly to the longitudinal axis of the channel and/or support structure.

A section of the reinforcement element can be inserted or inserted into the at least one groove of a fastening element. In the assembled state, a section of the reinforcement element engages in the at least one groove of the fastening elements or is inserted therein.

In the mounted state, the fastening element is preferably pushed into the reinforcement element in such a way that a U-shape of the reinforcement element surrounds the longitudinal sides of the fastening element.

In the mounted state, the reinforcement element is connected to the fastening element and the channel and/or support structure. The at least one groove of the fastening element is used to connect the reinforcement element, fastening element and channel and/or support structure. In the mounted state, the reinforcement element is preferably connected in a form-fitting manner to the fastening element and the channel and/or support structure. The term "positive connection" means that the cohesion of the reinforcement element, the fastening element(s) and the channel and/or support structure is ensured by the shape of the parts without constantly acting forces (prestressing). This applies to the two-sided form fit, in which the cohesion acts in two axial directions, as well as to a one-sided form fit, in which the cohesion works in a single axial direction direction works. In contrast to the form-fitting connection, in the case of the force-fitting connection, the cohesion of the components is achieved by constantly acting (external) forces.

1 shows a system according to the invention with a chute 20 and four devices 10 according to the invention. The devices 10 according to the invention support the chute 20 and are suitable for continuously adjusting the height of the chute 20.

2 shows a system according to the invention with a support structure 20 and four devices 10 according to the invention for supporting the gutter and for adjusting the height of the support structure.

Adjusting the height of the gutter 20 in 1 or the support structure 20 in 2 is also possible after assembly from above without any difficulties. It is only necessary to remove the grid 22 in order to access the devices 10 in 3 shown Allen 18 to obtain.

3 shows a hexagon socket 18 which forms one end of each of the threaded rods 12. The other end of the threaded rod 12 is pivoted in the foot 16 . By turning the threaded rod 12 through positive Power transmission via the Allen key 18, the threaded rod 12 can be moved up or down depending on the direction of rotation. The fastening element 11 is connected via an internal thread to an external thread of the threaded rod 12 and follows the movement of the threaded rod 12 up or down. The bottom 23 of the trough 20 in 1 or the support structure 20 in 2 is inserted into the groove 13 of the fastener 11. Due to the form-fitting connection of the fastening element 11 to the floor 23, the channel 20 or support structure 20 also follows the movement of the fastening element 11 and the threaded rod 12 upwards or downwards.

4 shows that the groove 13 divides the fastening element 11 into a (lower) part 11a and a (upper) part 11b. A web 11c connects the two parts. The fastening element 11 has a through-opening for the threaded rod 12 to pass through. The groove 13 is arranged perpendicularly to the longitudinal axis of the through opening.

figure 5 shows a method for assembling a device 10 according to the invention or the system according to the invention. The fastening element 11 includes in its (lower) part 11a a receptacle 14 for a hexagon nut 15. The internal thread of the hexagon nut 15 is used to connect the fastening element 11 to the external thread (not shown) of the threaded rod 12. The upper part 11b of the fastening element 11 is through an at least partially lateral receptacle 21 (see 14 ) of the channel or support structure 20 is pushed into the channel or support structure 20 in such a way that a section of the bottom of the channel or support structure 20 engages in the groove 13 of the fastening element 11 . Then the threaded rod 12 is guided from below through the hexagon nut 15, through the through-opening of the fastening element 11 and through a through-opening in the bottom 23 of the channel or support structure 20.

The external thread of the threaded rod 12 engages in the internal thread of the hexagon nut 15, so that the threaded rod 12, hexagon nut 15, fastening element 11 and bottom 23 of the channel or support structure 20 are fastened to one another. By rotating the threaded rod 12 via the Allen key 18, the height of the channel and/or support structure 20 can be adjusted from above at any time without further effort. The procedure comprises in this example performing the steps four times until four devices 10 are attached to the gutter or support structure 20 in order to adequately support the gutter or support structure 20 .

A receptacle of the channel or support structure 20 forms the lateral receptacle 21 for at least partially laterally inserting the fastening element 11 into the channel and/or support structure 20 and the through-opening in the base 23 of the channel or support structure 20 for receiving the threaded rod 12 and the Recording in the bottom 23 of the channel or support structure 20 for the web 11c of the fastening element 11.

15 shows a section through a system according to the invention. The channel or support structure 20 and the threaded rod 12 are electrically separated from one another by the fastening element 11 made of plastic. This enables a combination of different materials, such as galvanized steel and stainless steel.

16 12 shows a reinforcement member 19 which serves to reinforce the body of the support structure 20. FIG. When the channel is loaded and/or Bearing structure 20 from the top, the force is passed via the lateral grate supports to the height-adjustable feet 16. Since these feet 16 are not in a direct line to the introduction of force, a torque is produced here that bends the base 23 of the support structure 20 inwards. The reinforcing element or stiffening profile 19 prevents this effect, particularly if it is U-shaped and accommodates the fastening element 11 with its U-shape. The fastening element 11 connects the support structure 20 and the reinforcement element 19 to one another by being pushed on.
