Description

State of the art

[0001] EP 0 653 227 B1 discloses a device for releasably fastening a goal on a sports field.

[0002] From EP 2 092 350 B1 a connection system for connecting a device to a roof surface according to the preamble of claim 1 is known.

[0003] US 10 840 850 B1 and JP 2013-177789 A each disclose a connection system for connecting rail-like supports to a roof surface.

[0004] EP 3 940 301 A1 discloses a mounting device for a building device on a sloping roof surface.

[0005] It is an object of the invention to provide an improved connection system for connecting a device for cooling and / or heating a medium to a foundation. Disclosure of the invention

[0006] The invention is based on a connection system for connecting a device for cooling and / or heating a medium to a foundation, in particular a foundation inclined relative to a horizontal, such as a roof surface.

[0007] The connection system comprises at least one support element connected or connectable to the device for arranging on a foundation surface and at least one connecting element for connecting the support element to the foundation.

[0008] According to the invention, a connection system having the features of claim 1 is proposed.

[0009] In this context, a connection system should be understood in particular as a system for - in particular detachably - arranging and / or connecting and / or fixing at least two components to one another or with one another or to one another, in particular so that the connection remains permanently. The components to be connected here should in particular be a device and a foundation. In particular, the components touch at a point of contact or in a plane of contact, whereby the plane of contact can be thought of as spanning three or more points of contact. One or more connection systems can be used to connect the device to the foundation. The connection system is in particular connected to the device and / or can be connected.In this context, a device is to be understood as meaning, in particular, a heating device, a cooling device, a heat pump or an air heat exchanger device or a component thereof associated with the field of heating, air conditioning and ventilation technology. In particular, the device can be an outdoor unit of an air heat pump or a monoblock heat pump that can be installed in an outdoor environment. The device can be installed in an outdoor environment of a building, in particular on a roof of the building. Alternatively, the device can be installed essentially at ground level. The device uses air from the outdoor environment as a heat source and / or heat sink. A medium is to be understood as meaning, in particular, a liquid and / or gaseous heat transfer medium or a refrigerant, in particular an evaporable / condensable one. A foundation is to be understood as meaning, in particular, a permanently load-bearing substructure of the device.For example, this could be a wooden, concrete or plastic substructure in a beam, plank or panel construction. A foundation inclined relative to a horizontal should be understood here in particular to mean a foundation whose contact points or contact plane with the device do not lie in a horizontal plane. For example, a roof or a roof surface can represent such an inclined foundation. A foundation surface should be understood here in particular to mean the surface of the foundation facing the device, in which, for example, the contact points or the contact plane also lie. The foundation surface is designed in particular to absorb compressive and / or shear forces from the connection. In particular, the foundation surface is not designed to be as resilient as the foundation core.A foundation core is understood here in particular to be a foundation section capable of transmitting connecting forces, in particular compressive, tensile, shear and / or torsional forces. A support element is understood here in particular to be an element that is integrated with the device, in particular with a housing or a support structure of the device. Alternatively, the support element can also be an element that is formed separately from the device. The support element can be designed in the manner of a flange, a frame, a supporting structure or a base plate. The support element can in particular form the contact point or the contact plane of the device with respect to the foundation.A connecting element is understood here in particular to mean an element that establishes and / or secures the connection and / or fixation between the device and the foundation, which is particularly suitable for transmitting compressive, tensile, shear and / or torsional forces. A guide element is understood here in particular to mean an element that at least partially receives and / or guides and / or supports the connecting element, in particular so that a translational back / forward movement along a guide axis as well as a rotational movement about the guide axis are possible. Other translational degrees of freedom (transverse to the guide axis) and rotational degrees of freedom (tilting about other axes transverse to the guide axis) of the connecting element are restricted, in particular blocked.A guide axis is to be understood here in particular as a spatial axis which is defined by the intended interaction of the guide element and the connecting element.

[0010] The connection system according to the invention can be used to create a permanently secure, easy-to-install connection between the device and the foundation. The connection system is advantageously suitable for reliably absorbing forces and safely transferring them to the foundation. These include, for example, the weight of the device, operating forces due to start / stop and vibrations of a machine in the device, as well as disruptive forces from wind and vibrations in the installation environment of the device, each of which has particular compressive, tensile, shear, and / or torsional components. Particularly when the device is installed outdoors on the roof of a building, strong wind forces can act on the device and its connection to the foundation.Furthermore, the connection system and / or the guide element ensures that when mounting the device on the foundation, the connection element can be securely placed at a desired connection point in / on the foundation, since the connection element can be pushed in a target direction along the guide axis towards the desired connection point and fixed there.

[0011] According to the invention, the guide element is rigidly connected to the support element.

[0012] In particular, the guide element can be manufactured separately from the support element and then connected to the support element by force-fitting (e.g., screwed), form-fitting (e.g., riveted), or material-fitting (e.g., welded, soldered, or glued). Alternatively, the guide element can be formed integrally with the support element, for example, milled, cast, or injection-molded. The rigid connection ensures, in particular, that the possible translational and rotational movement of the connecting element relative to the support element is geometrically defined.

[0013] According to the invention, the guide element is sleeve-like and has a longitudinal extension, said longitudinal extension defining a longitudinal axis which runs substantially along the guide axis.

[0014] "Sleeve-like" here refers in particular to the shape of a hollow cylinder and / or tube. The guide element has a cavity that is particularly designed to accommodate and guide the connecting element. The longitudinal axis or the guide axis coincides in particular with the longitudinal cylinder axis (extrusion axis) of the hollow cylinder.

[0015] A cylinder is to be understood here in particular as a general cylinder, advantageously a circular cylinder.

[0016] In a further preferred embodiment, the guide element comprises a pipe section and has a through-opening extending longitudinally through the pipe section, wherein the through-opening is designed to receive and guide the connecting element.

[0017] A pipe section is understood here, in particular, to mean a section of a pipe with a cylindrical longitudinal bore. The pipe section has, in particular, a cut surface substantially perpendicular to its longitudinal axis or intersecting the longitudinal axis at an angle W in the range of 20° to 80°, preferably 40° to 60°, particularly preferably 60°.

[0018] According to the invention, the longitudinal axis of the guide element encloses an angle W with a support surface of the support element, wherein the angle W assumes a value in the range 20° to 80°, preferably 40° to 60°, particularly preferably 60°.

[0019] A support surface of the support element is to be understood here in particular as the contact plane of the support element and / or the device with respect to the foundation.

[0020] In the inventive design of the connection system, the connecting element is connected to the foundation at an angle W. This allows the various possible forces that may occur during the connection and during operation to be reliably and safely transferred to the foundation. In particular, shear forces acting between the support surface and the foundation surface can be converted into compressive forces on the foundation surface and tensile forces in the connecting element. This also ensures a permanently stable and secure installation of the device.

[0021] In a further preferred embodiment, the connecting element is, in particular, substantially bolt-shaped, in particular as a screw or threaded rod.

[0022] "Bolt-shaped" here refers specifically to cylindrical. The bolt-shaped connecting element can be easily and securely accommodated in the guide element, allowing it to be longitudinally displaced along a guide axis and rotated about the guide axis.

[0023] The associated dimensions, particularly transverse dimensions, of the connecting element (particularly an outer diameter) and the guide element (particularly an inner diameter of the through hole) are selected to resemble a clearance fit with minimal play, so that the connecting element moves only along the guide axis and rotates around the guide axis. In the other directions, only minimal translational and / or rotational movements are possible.

[0024] A further preferred embodiment has a further connecting element, in particular a nut thread and / or a screw nut, as a counterpart to the connecting element, in particular for arrangement in or on the foundation.

[0025] The further connecting element can be formed in one piece with the foundation, in particular the foundation core.

[0026] The connecting element can be designed in such a way that it automatically generates the associated additional connecting element during assembly. For example, the connecting element designed as a self-tapping screw can cut the nut thread into the foundation during assembly.

[0027] Alternatively, the further connecting element can be designed as a separate component, but arranged in / on the foundation, in particular the foundation core, and fixed there, in particular translationally and / or rotationally.

[0028] In a further preferred embodiment, the connection system, in particular the connecting element, is designed to establish a connection of the device to a foundation core arranged at a distance from the foundation surface.

[0029] In particular, a stably anchored element of the foundation, such as a beam of a foundation supporting structure (e.g., a roof supporting structure), or an auxiliary structure in / on the foundation supporting structure can serve as the foundation core. For example, an auxiliary structure, in particular made of wooden beams, can be anchored in / on the foundation supporting structure and adapted to the dimensions of the connection system and / or the device. The invention also relates to a device for cooling and / or heating a medium, which device is connected or connectable to a foundation, in particular a foundation inclined relative to a horizontal, such as a roof surface, and which has a connection system according to one of the above descriptions. Such a device can permanently fulfill its function reliably and safely because it is stably connected to the foundation. drawing

[0030] Further embodiments and advantages will become apparent from the following description of the drawings. The drawings illustrate exemplary embodiments of the invention. The drawings, the description, and the claims contain numerous features in combination. Those skilled in the art will expediently combine the features, provided that the subject matter thereby falls within the scope of the claims. They show: Figure 1 a perspective view of a device for cooling and / or heating a medium on a foundation inclined relative to a horizontal Figure 2 a perspective view of a connection system for connecting a device to a foundation Figure 3 a section through a connection system for connecting a device to a foundation Figure 4 a perspective view of a detail of a connection system Figure 5 a perspective view of a detail of a connection system Figure 6 a section through a connection system.

[0031] Figure 1 shows a perspective view of an outdoor device 10 for cooling and / or heating a medium, connected to a foundation 20 inclined relative to the horizontal 1, in this case a sloped roof surface. The connection system 100 for connecting the device 10 to the foundation 20 is concealed under a cover 12 (for details see Figures 2 to 6 ).

[0032] Figure 2 shows a perspective view of parts of a connection system 100, in particular the support element 102 connected or connectable to the device 10, for connecting the device 10 to the foundation 20, which are visible above / outside a foundation surface 22. The device 10, not shown, would be as in Figure 1 above the connection system 100, connected to it or connectable thereto.

[0033] The connection system 100 serves to connect the device 10 to a foundation surface 22 inclined relative to the horizontal 1, shown here using the example of a roof surface. The connection system 100 comprises a support element 102 connectable to the device 10, which is arranged on the roof surface 22. A connecting element 104 for connecting the support element 102 to the foundation 20 is shown in the Figures 3 and 6 shown. Six guide elements 106 connected to the support element 102 for receiving and guiding the connecting elements 104 can be seen.

[0034] Figure 3 shows a section through a connection system 100 and the associated foundation 20.

[0035] The foundation 20 can be seen with a foundation surface 22 and a foundation core 24. The support element 102 of the connection system 100 is arranged above the foundation surface 22. The foundation surface 22 is spaced from the foundation core 24. A thermal insulation layer 2, for example for thermally insulating a roof space, is arranged in an intermediate space between the foundation surface 22 and the foundation core 24. For connecting a device not shown here (10, but see Figure 1) with the foundation 20, the connection system 100, which can be connected to the device 10, overcomes this distance. The weight, operating, and disturbing forces from the device 10 are introduced into the foundation core 24 for a permanently reliable and secure connection. For this purpose, the connection system 100 has four connecting elements 104, visible here, for example in the form of screws 104. The two middle connecting elements 104 form an oblique angle W with respect to the foundation surface 22. However, the two outer connecting elements 104 also form an oblique angle W with respect to the foundation surface 22; however, this oblique angle runs in a plane perpendicular to the viewing plane and is therefore not visible in this view. The length of the connecting element 104 is based on the distance between the foundation surface 22 and the foundation core 24, as well as on the angle W between the connecting element 104 and the foundation surface 22.The connecting elements 104 are each in a guide element (106, details see . Figures 4 to 6 ). The angle W of the connecting element 104 results from the angle of the guide element 106. Due to the tightly toleranced guidance of the connecting element 104 in the guide element 106, the connecting element 104 is guided during assembly from the support element 102 through the guide element 106 to the foundation core 24 with little or no angular deviation, where it precisely meets the desired connection point. This is particularly important when the foundation core 24 is a narrow supporting beam that needs to be connected as precisely as possible in the center of the beam.

[0036] Since the support surface 103 of the support element 102 comes to rest on the foundation surface 22, the angle W between the connecting element 104 or guide element 106 on the one hand and the foundation surface 22 on the other hand corresponds to the angle W between the guide element 106 and the support surface 103 of the support element 102.

[0037] The connection system 100 can have a further connection element 112 arranged or arrangeable in or on the foundation 20, in particular the foundation core 24, in particular a nut thread and / or a screw nut, as a counterpart to the connection element 104. This allows the connection element 104 to be introduced into the foundation 20 particularly easily and securely.

[0038] Figure 4 shows an enlarged view of detail IV of the connection system 100 in Figure 2The section shown of the support element 102 of the connection system 100 has, on its underside (hidden here), the support surface 103 for resting on the foundation surface 22. The connection system 100 comprises a guide element 106—in particular rigidly connected to the support element 102—for receiving and guiding the connection element 104, wherein the guide element 106 only permits a translational movement of the connection element 104 in the direction of a guide axis 107 and / or a rotational movement about the guide axis 107. Only a head 105, in particular a screw head 105, of the connection element 104 can be seen here.

[0039] The guide element 106 is sleeve-like and has a longitudinal extension, this longitudinal extension defining a longitudinal axis 108 which encloses an angle W with a support surface 103 of the support element 102, the angle W assuming a value of 60°.

[0040] Figure 5 shows a perspective view of detail V of the connection system 100 in Figure 2 The section shown of the support element 102 of the connection system 100 has, on its underside (hidden here), the support surface 103 for resting on the foundation surface 22. The connection system 100 comprises two guide elements 106—particularly rigidly connected to the support element 102—for receiving and guiding a connecting element 104 each, wherein the guide element 106 only permits a translational movement of the connecting element 104 in the direction of a guide axis 107 and / or a rotational movement about the guide axis 107. Of the connecting elements 104, only a head 105, in particular a screw head 105, can be seen here.

[0041] The guide element 106 is sleeve-like and has a longitudinal extension, this longitudinal extension defining a longitudinal axis 108 which encloses an angle W with a support surface 103 of the support element 102, the angle W assuming a value of 60°.

[0042] Figure 6 shows a longitudinal section through a connection system 100 connected or connectable to a device 10 not shown here.

[0043] The connection system 100 comprises a support element 102 arranged on a foundation surface 22 and a connecting element 104 for connecting the support element 102 to the foundation 20. The connection system 100 is designed to connect the device 10 (not shown here, see Figure 1) with the foundation core 24 arranged at a distance from the foundation surface 22. The connection system 100 comprises a guide element 106 for receiving and guiding the connection element 104, wherein the guide element 106 only permits a translational movement of the connection element 104 in the direction of a guide axis 107 and / or a rotational movement about the guide axis 107. The guide element 106 is rigidly connected to the support element 102 so that during manufacture, assembly and / or operation of the connection system 100 there is no unwanted angular adjustment of the guide element 106 with respect to the support element 102. The guide element 106 is sleeve-like and has a longitudinal extension, wherein this longitudinal extension defines a longitudinal axis 108 which runs essentially along the guide axis 107.The guide element 106 comprises a tubular section 109 and has a through-opening 110 extending longitudinally through the tubular section 109, wherein the through-opening 110 is designed to receive and guide the connecting element 104. The guide element 106 is placed obliquely on the support element 102; for this purpose, the tubular section 109 has an oblique end face. The longitudinal axis 108 of the guide element 106 forms an angle W with the support surface 103 of the support element 102, wherein the angle W has a value of 60°. The connecting element 104 is bolt-shaped, for example, as a screw 104 with a screw head 105. The connection system 100 comprises a further connecting element 112, here a screw nut 112, as a counterpart to the connecting element 104, arranged in the foundation core 24.
