Description

[0001] Surface fastening device

[0002] The invention relates to a surface mounting device for attaching a mounting device, preferably for attaching at least one solar or photovoltaic module, to an inclined or vertical surface.

[0003] Up to now, fastening devices have simply been screwed to the surface. The surface fastening device consists, for example, of a single screw.

[0004] This makes assembly time-consuming on the one hand. On the other hand, the position of the fastening device is permanently fixed and unchangeable by the screw.

[0005] It is therefore an object of the invention to provide a surface fastening device and a method that enables simple and / or adaptable fastening of the fastening device.

[0006] This problem is solved by the subject matter and procedure of independent claims.

[0007] According to the invention, the surface fastening device is designed for fastening a fastening device and / or can be used for this purpose.

[0008] The fastening device can, for example, include an elongated support device, an elongated clamping device and / or a fixing device for fixing the clamping device to the support device, preferably steplessly.

[0009] Regarding possible embodiments, reference is made to German patent application DE 102024 111 883.0, the content of which is fully incorporated into this application. The carrying device, the clamping device and / or the fixing device preferably comprises or consists of a metal material, for example anodized, e.g. aluminum or (stainless) steel, and / or a plastic material.

[0010] Preferably, the fastening device is designed and / or can be used for fastening at least one solar or photovoltaic module to an inclined or vertical surface.

[0011] For example, the present invention may also relate to a system comprising a surface mounting device and the mounting device and / or at least one solar or photovoltaic module.

[0012] The inclined or vertical surface could be, for example, a facade, a wall, a boundary such as a fence and / or a wall, an overhang and / or a roof.

[0013] The angle of inclination can be, for example, between 70° and 90°.

[0014] The surface mounting device has a clamping unit for clamping the mounting device, preferably the support device.

[0015] The clamping unit enables easy and / or quick assembly.

[0016] The surface mounting device has a height adjustment device for adjusting the height position of the mounting device.

[0017] The height adjustment device is preferably designed to adjust the height position, for example in a direction parallel to the surface, e.g., to a wall. The surface mounting device, the clamping unit, and / or the height adjustment device preferably comprises or consists of a metal material, e.g., anodized aluminum or (stainless) steel, and / or a plastic material.

[0018] The surface mounting device fulfills a dual function. On the one hand, it can attach the mounting device, e.g., the support device, to the surface, and on the other hand, it can adjust the height position of the mounting device.

[0019] This makes assembly easier, for example, because there is a certain amount of play. This allows for some adjustment.

[0020] Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

[0021] According to one embodiment, the clamping unit has a swiveling device.

[0022] The swivel device preferably has a plate-shaped base body. For example, the base body can have a recess for an adjusting element. Preferably, the recess can have an internal thread.

[0023] Preferably, the swivel device is pivotably mounted on a fixed section of the clamping unit via a hinge and / or joint.

[0024] Preferably, the swiveling device is physically connected to the stationary section of the clamping unit, for example, during swiveling. The swiveling device and the stationary section of the clamping unit form, for example, a single component. A stop for the swiveling device may be provided. The stop may, for example, be made of or consist of a compressible and / or elastic material. The material may preferably be a rubber material, such as sponge rubber. This may, for example, be in the form of a round cord.

[0025] According to another embodiment, the clamping unit has an adjusting element for pivoting and / or fixing the pivoting device.

[0026] The adjusting element can be, for example, a clamping fastener, a toggle fastener, and / or a rotating element, e.g., with an external thread. The rotating element can be, for example, a screw, a threaded rod, and / or a bolt.

[0027] The adjusting element can, for example, be screwed into the recess of the base body and repulsed against a stationary section of the clamping unit.

[0028] The swivel device can be swivelled and / or fixed in the desired position.

[0029] According to another embodiment, the clamping unit has at least or exactly one clamping nose.

[0030] Preferably, at least or exactly two clamping lugs are provided.

[0031] A clamping lug can be formed, for example, on the swivel device, e.g., as an extension of the base body. Another clamping lug can be arranged, for example, on a stationary section of the clamping unit. The clamping lugs preferably engage in a groove of the fastening device, e.g., the support device. The groove can, for example, have at least one undercut.

[0032] According to another embodiment, the height adjustment device has a holding device to which the clamping unit can be attached or fastened in a height-adjustable manner.

[0033] The clamping unit can thus be adjusted and secured in the desired height position.

[0034] Since the mounting device is clamped to the clamping unit, the height position of the mounting device is also adjusted.

[0035] The holding device is preferably not height-adjustable, but fixed in place.

[0036] According to another embodiment, the height adjustment device has an adjusting element, preferably a screw, a threaded rod and / or a bolt, for adjusting and / or fixing the clamping unit relative to / on the holding device.

[0037] The actuating element can be, for example, a clamping fastener, a toggle fastener, and / or a rotary element, e.g., with an external thread. The rotary element can be, for example, a screw, a threaded rod, and / or a bolt.

[0038] An end portion of the actuating element can, for example, engage in a groove of the holding device. The groove can, for example, have at least one undercut. A screw head and / or a nut of the actuating element can thus be securely held. According to a further embodiment, the clamping unit has a base support which has a recess for the passage of a fastening element of the holding device.

[0039] The base support can, for example, be designed in the form of a plate.

[0040] The recess can, for example, be an elongated hole, preferably elliptically shaped.

[0041] The recess allows the fastening element, e.g. a screw, a threaded rod and / or a bolt, to be passed through the holding device.

[0042] The recess allows, for example, relative movement of the base support to the fastening element.

[0043] According to another embodiment, the surface fastening device, preferably the holding device, has a spacer tube.

[0044] The spacer tube can preferably penetrate insulation of the surface.

[0045] For example, the spacer tube can have a round cross-section.

[0046] According to another embodiment, the surface fastening device, preferably the holding device, has a pressure plate.

[0047] The pressure plate can provide a flat and / or stable support surface, e.g. for screwing on.

[0048] For example, the printing plate can have a round cross-section.

[0049] The invention also relates to a method for attaching a fastening device, preferably for attaching at least one solar or photovoltaic module, with a surface fastening device according to the invention to an inclined or vertical surface.

[0050] The clamping unit then wedges the mounting device in place.

[0051] The fastening device is held securely in this way.

[0052] Now the height position of the mounting device can be adjusted.

[0053] The mounting device can therefore be adjusted to the desired height position and attached there.

[0054] All embodiments and components of the device described herein are preferably designed to be assembled according to the method described herein. Furthermore, all embodiments of the device and all embodiments of the method described herein can be combined with one another, preferably also independently of the specific configuration in which they are mentioned.

[0055] It is generally noted that terms like "ein" (a) and "eine" (a / an) do not necessarily mean "exactly one" or "exactly one," although this is also possible. The terms "ein" and "eine" can therefore be understood as "at least one" or "exactly one." The use of the singular preferably includes the possibility of the components being plural, and vice versa.

[0056] It is noted that "vorzugsweise" and "bevorzugt" can be translated as "preferably" in English. A feature introduced by "vorzugsweise" or "bevorzugt" is purely optional, can be omitted, and does not constitute a limitation, for example, of the claims. The invention is described below by way of example with reference to the drawings. The drawings show:

[0057] Fig. 1 is a perspective view of an embodiment of a surface fastening device according to the invention,

[0058] Fig. 2 shows a side view of an embodiment of a system with a surface fastening device according to the invention without an end cap,

[0059] Fig. 3 shows a perspective view of the system according to Fig. 2 with end cap, and

[0060] Fig. 4 shows a perspective view of another embodiment of a

[0061] Systems with a surface fastening device according to the invention.

[0062] It should first be noted that the embodiments shown are purely exemplary. Individual features can be implemented not only in the combination shown, but also individually or in other technically feasible combinations. For example, the features of one embodiment can be combined with features of another embodiment in any way. The number, length, shape, and / or position of the respective components are essentially arbitrary. Furthermore, the end cap, the spacer tube, and / or the pressure plate are purely optional.

[0063] If a figure contains a reference numeral that is not explained in the immediately associated descriptive text, reference is made to the corresponding preceding or subsequent explanations in the figure description. Thus, the same reference numerals are used for identical or comparable components in the figures and are not explained again. Fig. 1 shows a surface mounting device 10 with a clamping unit 12.

[0064] The clamping unit 12 has a swiveling device 14 with a plate-shaped base body 16.

[0065] The base body 16 has a recess for an adjusting element 18 designed as a screw.

[0066] The swivel device 14 is pivotably mounted on a stationary section of the clamping unit 12 via a bearing 20 designed as a joint. A stop 22 can limit the maximum swivel angle.

[0067] As an extension of the base body 16, the swivel device 14 can have a clamping nose 24.

[0068] Another clamping nose 24 is arranged on the stationary section of the clamping unit 12.

[0069] The surface fastening device 10 has a plate-shaped base support 26 with a recess 28 designed as an elongated hole.

[0070] A height adjustment device 30 is used to adjust the height position.

[0071] The height adjustment device 30 has a holding device 31 to which the clamping unit 12 can be attached or fastened in a height-adjustable manner.

[0072] In this case, an adjusting element 32 designed as a screw can engage in a groove 34 of the holding device 31.

[0073] This can also be seen in Fig. 2. The surface fastening device 10 has a fastening element 36 which is guided through the elongated hole 28 and is attached to a pressure plate 38.

[0074] A spacer tube 40 and the pressure plate 38 enable attachment to a surface 42 designed as insulation, which is shown with a dashed line.

[0075] A fastening device 44 for fastening two solar or photovoltaic modules 46 is clamped to the clamping unit 12.

[0076] The clamping lugs 24 engage in a groove 48 of a support device 50.

[0077] The support device 50 is connected to a clamping device 54 via a fixing device 52. The fixing device 52 enables the clamping device 54 to be fixed to the support device 50, preferably steplessly.

[0078] An optional cover device 56 can cover the fixing device 52.

[0079] An end cap 58, which was omitted in Fig. 2 for better visibility, is shown in Fig. 3.

[0080] This can be attached to the front of the support device 50 and / or the clamping device 54.

[0081] As shown in Fig. 4, the surface mounting device 10 can also be used on uninsulated surfaces. The spacer tube 40 and the pressure plate 38 can then be omitted.

[0082] The surface mounting device 10 clamps the mounting device 44 and also provides height adjustment.

[0083] Assembly is therefore particularly easy. Reference list
