Description

The invention relates to a system for fixing a radiator to a wall. Such systems are known in the art. Part of these systems are often mounting rails, which are arranged vertically extending on a wall when used properly. Such mounting rails are referred to, for example, as radiator fasteners, mounting rails, wall brackets and / or the like. These are elongated profile elements, which are usually attached by two screw on a wall. The mounting rails can have a U-shaped profile in cross section. In addition, the support rails on holding means to hold a certain type of radiator can. In many applications, two mounting rails are used, which are spaced from each other attached to the wall. A radiator can then be hung in the mounting rails.
The known systems are not free from disadvantages. The possible radiator types to be mounted on a wall differ in size, weight, design and / or the like. Depending on the type of radiator, a very specific type of support rail is required. On the part of an installer, therefore, many different mounting rails must be maintained in order to install a corresponding range of radiator types.

Further, for example, from DE 76 05 588 U1 a system according to the preamble of claim 1 and thus a support frame for the construction of shelves and false ceilings, for hanging radiators and the like. From rail parts known. In this case, the support frame U-shaped rail elements with a rectangular, incomplete cutout at each end, wherein the rail elements are rotatably connected to each other by means of an extending in the horizontal direction intermediate strut.
But even this design is not free of disadvantages. In particular, the assembly is relatively difficult, since an orientation as to whether the device is oriented horizontally, only using other tools is possible.
The present invention is therefore based on the object to develop a generic system to the effect that simplifies the installation, usability and handling.
To solve the invention, a system according to claim 1 is proposed.

Radiator according to the invention means in particular a to be arranged on a wall radiator. That is, the radiator is disposed in a proper use in a vertical plane. It may be a ribbed radiator, a radiator made of sheet steel or steel pipe and / or the like.
A mounting rail is used to arrange a radiator on a wall. In this case, the support rail may have a selected upper part on the one hand and a selected lower part on the other. Both the lower part and the upper part serve to hold a radiator. The mounting rail can only consist of the lower part and the upper part. However, the mounting rail can also have other elements, such as a main body. The main body can connect the lower part with the upper part. The lower part, the upper part and / or the base body has means for attachment to a wall, for example a bore through which a screw can be passed. The lower part and the upper part have means for fixing the radiator.
A lower part serves to support the weight of a radiator. An upper part is used to securely hold the radiator to the device. The lower part may have a footprint for a radiator. This footprint may extend in the normal direction in the horizontal direction. The footprint thus extends at right angles to the direction of the longitudinal extension of the support rail. The upper part may have a retaining means for placement on a radiator. In a proper use of the radiator is then first positioned on the footprint of the base and then brought into connection with the holding means of the upper part. The radiator is then securely arranged on the mounting rail, and thus securely attached to the wall.
Preferably, a plurality of differently designed lower parts and upper parts is provided, which upper parts and lower parts are designed to be combined with each other according to the modular principle. The lower parts and upper parts are formed differently, in particular with regard to their length. Thus, there is a kind of reservoir of lower parts and upper parts of different training available, from which reservoir depending on the to be fastened to a wall radiator type each a suitable upper part and lower part can be selected. Subsequently, the upper part and the lower part can be connected to each other. Modular principle also means that each upper part with each of the lower parts can be combined or connected.
The advantage of a support rail which can be formed according to the system according to the invention consists in the simpler handling and usability compared with the prior art, since it is not an immutable in terms of usability, but is an individually assembled component. In addition, the number and the packing volume of parts to be kept by an installer are reduced since the individual upper parts and lower parts can each be used for several types of radiators. In contrast, according to the state of the art, each of these types of radiators would require its own mounting rail type.

According to an advantageous embodiment of the invention, the support rail has a base connecting the lower part to the upper part. The main body can be an elongate, rod-like element. The main body may be formed as a cross-sectionally U-shaped profile. At the free ends of the legs of the U-shape can join right angled extensions. Thereby, the bearing surface of the body can be increased on a wall. The main body may have two, in particular in the longitudinal direction end-side, areas in which the lower part and the upper part can be connected to the main body. For this purpose, the base body, the lower parts and the upper parts corresponding connecting means, for example, one, in particular provided with an internal thread, bore, latching and / or the like may be provided.

It may be provided universally usable with many types of radiator body. At this universally usable body then a required in each case of use lower part and an upper part can be arranged. This allows, for example, that a user already mounted the main body at a designated place of use on the wall, without which would have already decided which type of radiator is to be ultimately provided. If this decision is made, then the corresponding upper part and / or lower part can be mounted on the main body.

According to an advantageous development, a plurality of basic bodies of different lengths is provided, which basic body can be combined according to the modular principle with the lower parts and / or the upper parts, being arranged in the intended use case on one of the base body of the lower parts and / or one of the tops. The different basic bodies of such a construction kit can, for example, have different lengths. Additionally or alternatively, the basic body may differ with respect to the means for arrangement on a wall. For example, bores, elongated holes, adhesive surfaces and / or the like may be provided. The advantage is that the handling and usability is further improved.

According to an advantageous embodiment of the invention, the support rails are formed adjustable in length. As a result, one and the same device can be used with a wide variety of radiator types and / or sizes. For a particularly large radiator, the mounting rail can be extended accordingly. For a particularly small radiator, however, the mounting rail can be shortened.

According to an advantageous embodiment of the invention, the upper part and / or the lower part is designed to be movable relative to the main body. This allows a length adjustment of the mounting rail overall when using a body with a constant length. The upper part and / or the lower part may be guided like a rail on the base body. The advantage of this development is that the support rail can be adapted more flexibly to the particular type of radiator used.

According to an advantageous embodiment of the invention, the upper part and / or the lower part is arranged telescopically on the base body. The upper part and / or the lower part can / can be connected captively to the main body. Although the telescopic arrangement then allows a length adjustment of the support rail, however, the components of the support rail are securely held together. In the case of the lower part can be provided, for example, that the lower part in cross-section has a profile shape whose internal dimensions correspond to the outer dimensions of the profile shape of the base body. The lower part is then displaceable on the base body.

In accordance with the invention, a second mounting rail and a connecting element extending horizontally when used as intended are provided, wherein the mounting rails, in particular the base body of the mounting rails, are arranged non-rotatably on the connecting element.

In all hitherto known systems for fixing a radiator independent support rails are provided. Each mounting rail must be measured for mounting on at least two points on a wall. This is often already difficult, since there are a variety of conditions on the construction sites and especially a variety of building materials to which the mounting rails must be attached, are present. In addition, in addition to a defined distance between the mounting rails to each other as horizontal as possible alignment of the radiator is desired for correct operation. With the known devices therefore difficult handling, a lengthy assembly and the risk of suboptimal function of the radiator are connected by a deviating from the horizontal position.

The embodiment of the invention provides a remedy. The connecting element is used for the rotationally fixed connection of at least two mutually spaced support rails, which thus in particular the main body of the support rails are meant. The connecting element may be formed as an elongate rod element, for example, a square solid material. The connecting element has means for arranging the mounting rails. These may be openings for receiving screws, latching means, such as latchable with a mounting rail locking lugs, and / or the like.

The connecting element can be designed as a cross-sectionally U-shaped profile. At the two free ends of the legs of the U-shape can be followed by right-angled extensions. These serve to increase the contact surface of the connecting element of the mounting rails. A clou of the embodiment according to the invention is that the two spaced support rails are arranged on the connecting element. The device is thereby handled as a unit. The mounting rails are perpendicular to the connecting element. In addition, the two mounting rails preferably parallel to each other. The directions of the longitudinal extent of the mounting rails and the connecting element have a common normal in a proper arrangement. The device according to the invention thus has an overall H-shape. The advantage of this arrangement is that the two mounting rails can be handled together with the connecting element as a single component. The separate handling of the individual mounting rails known from the prior art is completely eliminated. The special feature is also that the support rails are rotatably mounted on the connecting element. Rotationally means that a rotation of the support rails relative to the connecting element, in particular at least in the plane defined by the two support rails common plane is prevented. Preferably rotatably means, however, that rotations of the mounting rails are prevented relative to the connecting element in all three spatial directions.

The mounting rails, in particular the base body, can be arranged directly, that is without the interposition of additional components, on the connecting element. But it can also be provided a coupling element which connects a mounting rail with the connecting element. This coupling element may on the one hand have a receptacle for the mounting rail and on the other hand an extension for insertion into the connecting element. The attachment of the support rail to the connecting element may be formed as a screw connection.

With this embodiment of the invention, an H-shaped device is provided in which two support rails are rotatably mounted on a connecting element. By this arrangement, the orientation of the two mounting rails is fixed to each other. There are no twists and / or the like possible. This makes it possible, for example, to grip and handle the device with only one hand. A user can arrange the device at the place of use, that is, for example, on a wall, with a first hand and drill holes and / or even drill holes with a second, free hand. Aligning the two mounting rails, both in terms of their distance and their orientation to each other, is completely unnecessary. The device, and in particular the suspension points, rather have predefined dimensions. These dimensions are matched to a type of radiator to be used. Thus, it can be ensured that, for example when using a ribbed heater, the mounting rails have such a distance from one another that they engage in intermediate spaces of the ribbed heater. The number of necessary installation steps for fixing a radiator to a wall is significantly reduced. The device according to the invention can be preassembled. The user can then use the device directly and without configuration measures. In addition, the entire process of fixing the radiator is much faster than with the devices known from the prior art equip. A known from the prior art measuring the mounting rails to each other is unnecessary. The fact that the components support rails and connecting element of the device are fixed in position to each other, only a one-time alignment of the entire device is required. Also, the horizontal alignment is particularly easy because a known leveling device, such as a spirit level, can be applied to the horizontally extending in the intended use connector.

According to the invention, the support rails are arranged displaceably on the connecting element. Displaceable means that the support rails in the direction of their longitudinal extension, that is, when used as intended in the vertical direction, can be moved relative to the connecting element. For this purpose, the carrier rails can have a slot through which a screw coupled to the connecting element is guided. The mounting rails can then be moved up and down on the screw, which leads to a corresponding displacement of the mounting rail relative to the connecting element. It is preferably provided that the support rails are formed in their displaceability relative to the connecting element blockable. For example, by tightening the screw, the mounting rail can be fixed to the connecting element. The advantage is that one user has the two Can guide rails and the connecting element in a desired configuration, then can block the mounting rails on the connecting element and then attach the device for its intended use on a wall. The displaceability can also be achieved by the coupling element. The coupling element may be formed as a kind of sliding block. The coupling element may have a rail-like receptacle for a mounting rail, in which the mounting rail can then be moved.
According to an advantageous embodiment of the invention, the connecting element is designed to be adjustable in length. The connecting element can be designed to be telescopic. The Längenversteilbarkeit allows the distance between the two mounting rails can be varied depending on the application. This contributes to a further improvement in handling and ease of installation.
According to the invention, the device has a leveling device, in particular a spirit level. The leveling device is arranged on the connecting element. The leveling device is used to detect whether the orientation of the device is aligned horizontally. This can be achieved without further aids or tools that a user can align the device very precisely and basically only with one hand on a desired wall. The assembly is thus further simplified and shortened in time. Particularly advantageous is the use of a spirit level. Spirit levels are very simple and inexpensive to manufacture. They consist of a drawn dragonfly, which is aligned to the exhibition levels. This is a slightly curved plastic or glass tube filled with a liquid and an air or gas bubble.
Further advantages and features will become apparent from the following description of the figures. Showing:

• FIG. 2 the connection between the mounting rail and connecting element in a sectional view along the section line II-II according to FIG. 1 ; and
• FIG. 3 A second preferred embodiment of a device according to the invention formed in a perspective view device.

FIG. 1 shows a first preferred embodiment of a device according to the invention formed by the device. The device has two mounting rails 1 and a connecting element 2. The support rails 1 and the connecting element 2 are rotatably connected to each other.
Each of the mounting rails 1 has a main body 3 on the one hand and a lower part 4 and an upper part 5 on the other. The lower part 4 and the upper part 5 are each connected to one end of the main body 3. The basic body 3 is formed as a cross-sectionally U-shaped profile, extending from the free legs of the U-shape of right angled extensions. The lower part 4 has a U-shaped profile in cross-section. The inner dimensions of the profile of the lower part 4 correspond to the outer dimensions of the profile of the base body 3. The lower part 4 can be pushed onto the base body 3. Through a hole in the lower part 4, a screw 6 is guided, which engages behind the main body 3 in an internal thread and thus countered there. By tightening the screw 6, the base body 3 and the lower part 4 brace. The lower part 4 is then immovably fixed to the base body 3.
The upper part 5 is inserted into the main body 3. For this purpose, the upper part 5 has a connection region with a cross-section whose outer dimensions correspond to the internal dimensions of the profile of the main body 3. Through an opening of the base body 3, a screw 7 is guided, which engages in an internal thread of the upper part 5. By tightening the screw 7, the upper part 5 and the base body 3 can be braced against each other. The parts are then frictionally connected with each other.
This design of the support rails 1, these are telescopically extendable and can be adjusted in its vertical length to the height of the radiator.
The two mounting rails 1, more precisely the two base bodies 3, are connected to the connecting element 2 with the interposition of a coupling element 11. The coupling element 11 has on the one hand a U-shaped receptacle which can be plugged onto the base body 3. On the other hand, the coupling element 11 on a block-like extension on which the connecting element 2 can be attached.
The clou of this coupling element 11 is that a rotationally fixed arrangement of the support rails 1 is achieved on the connecting element 2. The two support rails 1 are thereby fixed in their orientation to each other. In addition, the distance between the two mounting rails 1 is fixed to each other.

In addition, the mounting rails 1 in the U-shaped receptacle of the coupling element 11 are linearly movable. So there are certain adjustment options for the user. If a desired setting is reached, a screw 12 penetrating the connecting element 2, the coupling element 11 and the mounting rail 1 can be tightened. The mounting rail 1 and the connecting elements 2 can be fixed by the screws 12 in their relative position to each other.

The arrangement of the two mounting rails 1 and the connecting element 2 can be handled as a unit. This facilitates the attachment of the device to a wall immensely. It is also advantageous that on the connecting element 2, a spirit level 13, in particular captive, is arranged. The spirit level 13 has a dragonfly in a conventional manner. By the spirit level 13, the horizontal alignment of the device can be enormously simplified without further tools.

By provided in the base body 3, the upper parts 5 and the lower parts 4 slots 14 screws can be inserted, which then serve the connection to a wall.

FIG. 2 shows a cross-section through the connection region of the support rail and connecting element 2. The section extends in the direction of the longitudinal extent of the connecting element 2, in a plane which coincides with the intended use of the device with the horizontal plane.

The representation according to FIG. 2 is the previously described profile of the base body 3 in cross-section can be seen. In the main body 3, a nut 15 is received. On the base body 3, the coupling element 11 is arranged, which surrounds the body 3 partially with its U-shaped receptacle. Attached to the coupling element 11 is the connecting element 2. Through an opening in the connecting element 2, a further opening in the coupling element 11 and yet another opening in the base body 3, the screw 12 is passed through the screw 12 engages the nut 15. By tightening the screw 12, the connecting element 2, the coupling element 11 and the base body 3 of the support rail 1 can be interconnected. The nut 15 may have a quadrangular or hexagonal outer contour. This can ensure that they can not rotate freely within the body 3. Shown is also a holding means 10 of the upper part. 5

The intended use of this device described above proceeds as follows. The unit of the two mounting rails 1 and the connecting element 2 is arranged on a wall. By an orientation depending on the Measurement result of the spirit level 13, the connecting element 2 can be brought into a horizontal position. Due to the rotationally fixed arrangement of the mounting rails 1 on the connecting element 2, the mounting rails are then necessarily in a vertical position. Subsequently, drill holes can be marked through the slots 14 therethrough. But it is also conceivable that the holes are drilled directly through the slots 14 therethrough. Then the unit can be bolted to the wall provided.

A radiator is then placed on shelves 8, 9 on the lower parts 4. Depending on the type of radiator used, a lower part 4 can be used with a footprint 8, 9, which footprint 8, 9 is adapted to the respective geometric shape of the radiator. As a result, an optimized fixation of the radiator can be achieved. The installation surfaces 8, 9 run horizontally when the unit is used as intended. The footprint 8, 9 provide an ideal for the respective type of radiator support surface.

Subsequently, the radiator is brought into a vertical position, whereupon provided on the upper parts 5 holding means 10 can be connected to the radiator. The holding means 10 have a hook shape. The upper parts 5 and the holding means 10 are adapted in their geometric shape to the radiator type. This allows you to encompass corresponding ribs or other fasteners on the radiator. Subsequently, the holding means 10 can be fixed in a position encompassing the radiator. The radiator is then securely fastened to the wall. In addition, it is ensured that the holes were hit exactly and thus the radiator is in an improved horizontal position. In addition, the adapted to the shape of the radiator shells 5 and lower parts 4 particularly reliable prevent tilting or slipping of the radiator.
