Abstract

In the present invention, there is disclosed a frame (1) for air-conditioning devices in a rectangular box-like structure, preferably in the form of an rectangular having corner portions (2, 6) comprising each three profile adapters (5), aligned to axes of a spatial coordinate system on which profiled strips (4), forming side edges of the frame, are put and fastened. In the region of the faces of the profiled strips (4) the frame (1) surrounds at least partially on all sides cover plates (3) and is characterized in that fastening of each profile strip (4) on the corresponding profile adapter (5) of the corner portion (2, 6) is made by means of a bolt (7) that is guided in imaginary plane (8) of cross section of both the profile adapters (5) arranged perpendicularly to the profile strip (4) to be fastened.

Description

AIR CONDITIONING FRAME

Technical field

The invention relates to a frame for air conditioners according to claim 1.

BACKGROUND OF THE INVENTION

Such frames for air conditioner cabinets consist of a galvanized frame structure made of a steel profile which seals to ensure a tight seal with covers. The problematic parts of the frame structure are the corner parts. They must, on the one hand, have sufficient rigidity to hold the entire frame and give a favorable cuboid shape and, on the other hand, they must be easy to manufacture in order to guarantee the shortest possible production time.

In the known frames, the corner parts consist of short steel profiles which are cut in their end regions so that they can be assembled along the axes of the spatial coordinate system. The fastening is then carried out using substantially U-shaped sheets, which are fastened externally to the steel profiles by means of screws and thus form a connection between the steel profiles. The profile sections, which form the lateral edges of the frame, are then flush-fitted onto the corner section with the three profile extensions and then fixed by means of screws. In this case, each profile rail is fastened to the profile extension by means of two screws, the two screws being fixed to the external surfaces of the profile rail, which are mutually aligned at right angles.

The problem with this type of connection is that many corner manufacturing operations are required, as well as many of the necessary screw connections for securing the profile rails to the corner extension profile extensions. For one corner part, 6 screws are required to attach the profile rails to the profile extensions. Thus, 48 screws are required for the entire air conditioner cabinet.

SUMMARY OF THE INVENTION

The object of the invention is to propose a new type of frame for an air-conditioning cabinet which is considerably simpler and can be produced with less material consumption and fewer work steps and thus faster.

This is achieved according to the invention with the features of claim 1.

As a result, each profile rail can be fastened to the respective profile attachment with only one screw. Due to their symmetry, this type of fastening not only guarantees sufficient stiffness of the corner parts, but only more than half of the work steps are required for fastening the profile rails on the profile extensions. This significantly reduces the number of screws in the air-conditioning box. Substantial reduction of the working steps in this case also means a substantial reduction of the working time for assembling the frame.

According to claim 2, the screw heads for securing the profile rails on the profile extensions of the corner parts are prevented from protruding from the air-conditioning cabinet frame and thus pose a risk of injury.

The features of claim 3 provide for a particularly strong connection of the profile rails on the profile extensions, and thus a very stable alignment of the corner parts.

The feature of claim 4 is the advantage of the extremely fast and uncomplicated production of the corner parts, whereby the screwing of the profile extensions is no longer necessary to form the corner part.

BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1, the cover plates 3 are held in the frame 1. The cover plates 3 seal (not shown) to seal the space 9 formed by the frame 1. The space 9 serves to accommodate a variety of air conditioners (not shown).

The corner part 2 is shown in greater detail in FIG. 2 and 3, wherein FIG. 3 shows a section along the line A - A as seen in FIG. Second

The frame 1 consists of profile rails 4 having undercut 13 and stop rails 14 for receiving the covers 3, the profile rails 4 being pushed onto the profile extensions 5 (indicated by the dashed lines). Each of the three profile extensions 5, which are preferably made of plastic and can therefore be produced in one piece, forms a corner part 6. The fixing of the profile strip 4 on the respective profile extension 5 is effected by a screw 7 which is essentially guided in an imaginary plane. In this case, the screw 7 penetrates the profile rail 4 and the profile extension 5 at their edges 10, 11 facing the interior space 9. Furthermore, the screw 7 also penetrates into the outer edge 12, which faces opposite the inner edge 11 of the profile extension 5.

With the fastening according to the invention, the profile rails are reliably fixed to the profile extensions, whereby considerably fewer operations and substantially less material are required compared to the prior art.

Claims (4)
