The disclosure relates to a frame profile for a frame rack of a service cabinet.
This section provides background information related to the present disclosure which is not necessarily prior art.
Frame profiles are known in many embodiments, profiles according to DE 195 36 950 C1, EP 0 789 983 B1 and EP 1 601 074 B1 are cited only by way of examples. All these profiles have a more or less complex structure, wherein there is a desire by the manufacturers and also by the users to save material and to have many functionalities available.
The disclosure therefore has the problem of making a frame profile available for a frame rack of a service cabinet which makes a savings of material possible with a uniform rigidity and portability for a suspension chassis.
According to the disclosure the frame profile consists of an outer profile part manufactured from a first material, wherein the outer profile part forms at least a first wall of the frame profile which partially limits a hollow chamber, and of an inner profile manufactured from a second material which differs from the first material by at least one quality, wherein the inner profile forms at least one other wall of the hollow chamber. For example, the outer profile part can consist of a material which is more resistant to corrosion than the material of the inner profile part.
It can also be provided that the thickness of the outer profile part differs from the thickness of the inner profile part, in particular is greater than the thickness of the inner profile part.
This section provides a general summary of the disclosure, and is not a comprehensive disclosure of its full scope or all of its features.
A particularity of the frame profile according to the present disclosure consists of a hollow chamber, which is preferably open over the entire length of the frame profile. Therefore, an option space is available in the hollow chamber which can be used in many ways. Therefore, cables can be run through the hollow chamber, for example, for data lines, which are then screened by the material of the outer profile part and of the inner profile part and are therefore protected from disturbances.
It can also be provided that the hollow chamber is reinforced with a hard foam. Likewise, fillings with soft foam are conceivable so that the hollow chamber develops damping qualities. Even structures with open pores, in particular soft foams with open pores can be provided that allow a medium to be transported.
The hard foam or the soft form can be a foam based on polyester or polyurethane. Even metallic foams are conceivable as well as concrete and other inorganic or organic materials.
Therefore, a plurality of profiles with very different qualities is possible with the same functions and outside dimensions without the functional geometry being changed. Therefore, the hollow chamber can be shaped in such a manner that the profile qualities can be adjusted.
According to a preferred embodiment of the disclosure the outer profile part and the inner profile part can be brought together to at least one profile attachment which extends away from the hollow chamber. This therefore produces a straight-line web with an angular contour onto which an application seal can be set. The latter can be a customary lip seal but also a seal like the one forming subject matter of DE 10 2014 101 401 A1 filed at the same time.
Furthermore, it can be provided that the inner profile part is folded in order to form at least one profile attachment. Therefore, given only one half the material thickness a certain fastening thickness can be retained or the latter can be enlarged in spite of a clamping of the material. Therefore, sufficient material thickness is made available e.g. for sheet screws for which a minimum thickness is required.
The hollow chamber is preferably rectangular or quadratic in cross section but can also be constructed as a trapezoid or as a parallelogram, that is, like a rhombus. Furthermore, the profile attachment or the profile attachments is/are formed on edges of the hollow chamber. It is provided in this case that the profile attachments enclose an angle of 135° with the adjacent profile sides. In the case of four profile attachments on the four corners of the hollow chamber this results in a symmetrical frame profile whose profile attachments satisfy different requirements.
It is preferred that the folded profile attachments are provided with a perforation, preferably a system perforation. In the case of two such profile attachments several structural planes results so that work can be done with a suitable chassis with the same parts on the same fastening plane. The mounting of components is possible here from both sides of the particular profile attachment.
A frame rack can be built up from frame profiles according to the disclosure for a service cabinet in which such a frame profile is constructed at least as a vertical profile in order to be to utilize the improved possibilities of assembly. However, it is just as advantageous to also use the frame profile of the present disclosure as a horizontal profile, namely in the cover area as well as in the bottom area. Precisely in the bottom area the corner solution can then be made in a more material-saving manner if the inner profile part is constructed to be shorter than needed by the dimensions of the cabinet so that it does not have to be subsequently notched or only very little notched.
The drawings described herein are for illustrative purposes only of selected embodiments and not all possible implementations, and are not intended to limit the scope of the present disclosure.
The disclosure is explained in detail in the following using the attached drawings. The views are not necessarily true to size. In the drawings:
Example embodiments will now be described more fully with reference to the accompanying drawings.
The hollow chamber 40 can be used for running cables. Even fillings with hard foam or soft foam, for example based on polyester or polyurethane are possible in order to stiffen the frame profile 10 or to impart damping qualities to it.
The angular design of the inner profile part 30 can be clearly recognized in
A corner connection in the bottom area of a frame rack with frame profiles 10a, 10b and 10d in accordance with the present disclosure is shown in
The frame profile according to the present disclosure therefore offers a savings of material without limiting the functionality.
The features of the disclosure disclosed in the present specification, the drawings and in the claims can be essential individually as well as in any combination for carrying out the disclosure.
The foregoing description of the embodiments has been provided for purposes of illustration and description. It is not intended to be exhaustive or to limit the disclosure. Individual elements or features of a particular embodiment are generally not limited to that particular embodiment, but, where applicable, are interchangeable and can be used in a selected embodiment, even if not specifically shown or described. The same may also be varied in many ways. Such variations are not to be regarded as a departure from the disclosure, and all such modifications are intended to be included within the scope of the disclosure.
