DETAILED DESCRIPTION OF EMBODIMENTS

[0050] It is to be understood that the figures and descriptions of the present invention have been simplified to illustrate elements that are relevant for a clear understanding of the present invention, while eliminating, for purposes of clarity, many other elements which are conventional in this art. Those of ordinary skill in the art will recognize that other elements are desirable for implementing the present invention. However, because such elements are well known in the art, and because they do not facilitate a better understanding of the present invention, a discussion of such elements is not provided herein.

[0051] The present invention will now be described in detail on the basis of exemplary embodiments.

[0052] FIG. 1 shows a control cabinet 1 in an indicated form, although any cabinet or even a housing can be addressed instead of this control cabinet. The control cabinet 1 contains a housing body 2 and a door 3. The door 3 can be opened or closed via a suitable closure system 4.

[0053] The top image in FIG. 1 shows the closed state of the door 3, while the bottom image in FIG. 1 represents the opened state.

[0054] A fitting 5 interacts with the closure system 4 and terminates in a locking tongue 6 in its free end region. As will be described in more detail later, the locking tongue 6 has a profiled portion 7 which, forming an approach slope, engages behind a wall portion 8 of the housing body 2. In this example, the fitting 5 is designed as an elongated body, although contours depicted in the prior art are also conceivable.

[0055] FIGS. 2a to 2c show different illustrations or sections, respectively, of the sliding block 9 according to the invention. The sliding block 9, which is designed as an injection-moulded part, consists of POM. The sliding block 9 is formed in one piece and has the following elements:

[0056] a base portion 10, lateral wall portions 11, 12 and a cover portion 13. Depending on the configuration of the locking tongue 6 shown in FIG. 1, the base portion 10 and/or the cover portion 13 is provided with suitable profiled regions 14. In the region of the end face 15 of the base portion 10, which contains the cover portion 13, a web 16, which is moulded on by injection moulding, extends between the cover portion 13 and the base portion 10, which web can serve as a stop for the mounted locking tongue 6. On the cover portion side, in this example, bead-shaped latching means 17 are provided, which extend in the direction of the base portion 10. The shape and configuration of these latching means 17 can be of any type and are adapted by the person skilled in the art to the respective profile shape of the locking tongue 6. The sliding block 9 according to the invention has a resiliently designed guide region 18 outside the cover portion 13, wherein the spring effect is produced by slots 19 made in the base portion 10 and in the wall portions 11, 12. In the resiliently designed guide region 18, guide elements 21 provided with profiles 20 are moulded on, which in the mounted state can be operatively connected to corresponding wall portions of the locking tongue 6.

[0057] FIG. 3 shows a mounting step, which is only indicated, of a fitting 5 shown in FIG. 1. The locking tongue 6, which is provided with a profiled portion (approach profile) 7, and the sliding block 9 described and illustrated in the previous figures, can be seen. The locking tongue 6 of the fitting 5 is inserted at a predeterminable angle into the insert opening 22 of the sliding block 9 formed between the base portion 10 and the cover portion 13, the fitting 5 or the locking tongue 6, respectively, being positioned relative to the sliding block 9. After the locking tongue 6 has been introduced into the insert opening 22, namely up to the web 16 forming a stop, the fitting 5 can then be moved in the direction of the arrow, so that the resiliently designed guide elements 20 of the resiliently designed guide region 18 can be operatively connected to corresponding wall portions 23 of the locking tongue 6.

[0058] FIG. 4 shows the mounted state of the fitting 5 in different views or sections, respectively. In addition to the sliding block 9, the locking tongue 6 can also be seen. The latching means 17 formed by a bead or an undercut in the region of the cover portion 13 engages behind the profile 7 of the locking tongue 6, so that in this state a releasable connection between the locking tongue 6 and the sliding block 9 is established. The resiliently designed guide region 18, or the guide elements 20, 21, respectively, rest in the mounted state on the wall portions 23 of the locking tongue 6 already mentioned.

[0059] FIGS. 5 to 8 illustrate an alternative configuration of the sliding block 9 shown in the previous figures, meaning that the same reference signs apply to the same components.

[0060] FIG. 5 shows the mounted state of the alternative sliding block 9 on a locking tongue 6 in different views or sections, respectively. As already mentioned, the locking tongue 6 is part of a fitting 5.

[0061] The latching means 17 are also formed by a bead here, but in contrast to the previous figures, they are not provided in the region of the cover portion but in the region of the lateral wall portions 11, 12.

[0062] FIG. 6 shows the alternative configuration of the sliding block 9 according to the invention as an alternative to FIGS. 2a to 2c. The following elements can be seen:

[0063] the base portion 10, lateral wall portions 11, 12 and the cover portion 13. Depending on the configuration of the locking tongue 6 shown in FIG. 5, the base portion 10 and/or the cover portion 13 is provided with suitable profiled regions 14. The latching means 17 provided on the lateral wall portions 11, 12 overlap the locking tongue 6 in the mounted state.

[0064] FIG. 7 shows the sliding block 9 according to FIG. 6 in different spatial views. The latching means 17 provided on the lateral wall portions 11, 12 can be seen.

[0065] FIGS. 5 to 7 show a widened version of the sliding block 9 compared to the previous figures. This has the advantage that the approach slope is almost doubled, which considerably improves the closing process, in particular if a seal is to be pressed in.

[0066] FIG. 8 shows a schematic diagram of the mounting process of the sliding block 9 according to FIGS. 6 and 7. The locking tongue 6, which is provided with a profiled portion (approach profile) 7 and which is part of a fitting 5, can be seen. The locking tongue 6 of the fitting 5 is inserted at a predeterminable angle into the insert opening 22 of the sliding block 9 formed between the base portion 10 and the cover portion 13, the fitting 5, or the locking tongue 6, respectively, being positioned relative to the sliding block 9. After the locking tongue 6 has been introduced into the insert opening 22, namely up to the web 16 forming a stop, the fitting 5 can then be moved in the direction of the arrow After the locking tongue 6 has been inserted into the sliding block 9, the latching means 17 overlap the locking tongue 6.
