Description

The invention relates to a system comprising a component of an air conditioning system with an opening, in particular a component with a provided in a housing wall inspection opening, and a closure element for closing the opening, wherein the closure element completely covers the opening in its closing position on the outside and at least partially in includes the insertion opening projecting into the opening.

A system according to the preamble of claim 1 is known from EP-2 199 701-A known.

In a component of an air-conditioning system? such as a channel element, an inspection opening may be provided, which is closable with a closure element. This closure element can be removed for maintenance purposes, for example, and then reassembled. A known closure element has a cylindrically shaped insertion region which projects into the opening. For fixing nuts are welded onto the component. The closure element has corresponding holes through which screws can then be passed. However, the assembly and disassembly is time consuming. Since it is several and sometimes even small components, these can easily be lost.

The object of the invention is to avoid the aforementioned disadvantages and to provide a system whose closure element is easier to attach and also equally easy to remove again.

This object is achieved in that the insertion region and the opening polygonal, in particular hexagonal, are formed, wherein the insertion region is dimensioned in relation to the opening, that the insertion region is insertable through the opening, and that at least portions of the edge regions of the opening and formed by the insertion area in the manner of a bayonet closure, so that the closure element by twisting in the closing direction, d. H. from the mounting position in its Verschließposition, is displaced. For assembly, only the insertion area has to be inserted into the opening and then the complete closure element has to be turned clockwise or counterclockwise into its closing position. Any aid is not required. The assembly and disassembly is very easy. Other previously required components, such as screws, therefore can not be lost.

The partial regions of the edge regions of the opening of the component and of the insertion region of the closure element, which are designed in the manner of a bayonet closure, can be arranged at least in one corner, in particular in all corners. In particular, in an arrangement in which in each corner of the opening on the one hand and the insertion on the other hand, the art a bayonet closure formed portions of the edge regions are arranged, the closure element is securely fixed over its circumference.

The formed in the manner of a bayonet closure portions of the edge regions of the opening and insertion can be configured as a tongue and groove connection, either the groove is disposed in the edge region of the insertion and the spring is formed by the edge region of the opening or the spring through the edge region of the Insertion region is formed and the groove is arranged in the edge region of the opening, wherein in the closing position, each spring is received in its corresponding groove.

If the component is, for example, a channel housing made of sheet metal, it is advisable if the edge region of the opening represents the spring and the groove is arranged in the edge region of the insertion region. In the closing position, the spring, i. H. in this case, the edge region of the opening, received in the corresponding groove of the insertion.

In a preferred embodiment, at least one groove is arranged in the edge region of the insertion region, in particular in the edge region of the corner of the insertion region, and this groove is on the one hand by a surface of the closure element in contact with the outside of the component in the closure position, in particular planar contact is, and on the other by a laterally opposite the insertion projecting portion formed.

In order to achieve a self-closing closing of the closure element, it is advisable if the distance A between the surface of the closure element and the portion decreases in the closing direction, as seen in the direction of closing obliquely in the direction of the surface in the Verschließposition with the outside the component is in contact, facing. When twisting in the closing direction, the closure element thereby pulls itself tight.

The insertion area and the opening may have the same number of corners.

The closure element may have an outside actuating handle. This allows easy assembly and disassembly of the closure element from the outside.

At least one corner of the lead-in area and / or at least one corner of the opening can be rounded. This avoids sharp corners and reduces the risk of injury.

The closure element may be made of metal or another suitable material.

The closure element may, at least in the area cooperating with the edge of the opening, preferably completely made of plastic.

In all figures the same reference numerals are used for identical or similar components.

In the figures, a section of a component 1 with a hexagonal opening 2 is shown. The opening 2 can be closed with a closure element 3, which has an insertion region 4 with also six corners.

Such as the Fig. 2 and 6 can be seen, the corners of the opening 2 and the corners of the insertion 4 are rounded.

The insertion region 4 is chosen in terms of its dimensions so that it is slightly smaller than the opening 2 in the component 1, so that the insertion region 4 can be inserted in the mounting position in the opening 2 and pulled out of this.

In Fig. 6 the closure element 3 is shown with its inserted into the opening 2 insertion region 4 in its mounting position. It can clearly be seen that the corners of the insertion area 4 and the corners of the openings 2 are aligned with each other.

Fig. 8 shows a side view of one of the six corner regions of the closure element 3. The edge of the opening 2 in the component 1 is not shown. As Fig. 8 can be seen, are partial areas of the edge regions, namely the corners of the opening 2 of the component 1 on the one hand and of the insertion 4 of the closure element 3 on the other hand in the manner of a bayonet closure, each comprising a spring 5 and a groove 6 is formed.

The spring 5 is formed by the edge region of the opening 2. The groove 6 is arranged in the illustrated embodiment in the edge region of the insertion region 4. Each groove 6 is on the one hand by a surface 7 of the closure element 3 and a possibly thereon seal 10, which in the Verschließposition is in contact with the outside of the component 1, and on the other hand formed by a laterally opposite the insertion 4 projecting portion 8.

When viewed in the closing direction 9, the distance A between the surface 7 of the closure element 3 and the section 8 decreases since the section 8 seen in the closing direction 9 obliquely in the direction of the surface 7, which is in contact with the outside of the component 1 in the closing position, is aligned. As a result, the edge of the opening 2 is increasingly clamped in its Verschließrichtung 9 with rotation of the closure element 3 and thus the locking element 3 is fixed by clamping in front of an unwanted loosening.

As in FIG. 9 is shown are on the surface 7 of the closure element 3, which is in the Verschließposition with the outside of the component 1 in the illustrated embodiment in surface contact, two circumferential seal 10 is provided, which may be foamed, for example. The seals 10 are in Fig. 8 been cut out. Each seal 10 also serves to adapt to different strengths of component 1.

Such as in Fig. 7 Recognizable, the groove 6 in the middle of a corner of the insertion region 4 is the lowest, while the depth of the groove 6 decreases to the two sides of the groove 6 out. The six straight, two adjacent corners connecting edge regions 11 have no groove 6.

For closing, the closure element 3 in the in Fig. 8 shown embodiment rotated clockwise. Thus, serving as a spring 5 edge region of the opening 2 in the respective groove 6 of the insertion 4 recorded. The closure element 3 contracts with increasing twisting due to the oblique orientation of at least one section 8 itself, so that the closure element 3 sealingly closes the opening 2 and also can not come loose.

As in Fig. 1 illustrated, the closure element 3 on an outside actuating handle 12.
