The invention relates to a fastening device 1 for fastening an installation box 100, in particular a distribution box 110, in a wall-shell opening 210 introduced into a wall shell 200.
The fastening device 1 comprises at least one fastening element 10. According to the two exemplary embodiments of the fastening device 1, the fastening device 1 comprises four fastening elements 10.
As can be seen in particular in Figures 1, 2, 17 and 18, the fastening element 10 comprises a first side 12 and a second side 14. The first side 12 faces away from a rear side 220 of the wall shell 200 in an intended position of the distribution box 110 in the wall-shell opening 210, and the second side 14 faces towards a rear side 220 of the wall shell 200. The fastening element 10 comprises a gripping arm 20 having a first end 16 and a gripping portion 20a which is arranged next to the first end 16 on the second side 14. The gripping arm 20a is suitable for acting on the rear side 220.
The fastening element 10 comprises a stop 22 next to a second end 18. Preferably, the stop 22 is arranged on the second side 14 of the fastening element 10.
The fastening element 10 extends substantially in an extension direction E. The stop 22 is preferably formed by a protrusion which protrudes transversely to the extension direction E. The first side 12 comprises a first bearing portion 24. The second side 14 comprises a second bearing portion 26. The second side 14 additionally comprises a third bearing portion 28 and a fourth bearing portion 30. The first side 12 can also comprise a fifth bearing portion 32.
The third bearing portion 28 is formed by a curved face 27 which transitions into an inclined plane 29 which is inclined towards a first end 16 of the fastening element 10 with respect to the extension direction E. The inclined plane 29 leads into a depression 31, wherein preferably the inclined plane 29 and the depression 31 are bounded laterally by at least one wall 33, wherein the wall 33 extends preferably parallel to the extension direction E. The fastening element 10 also comprises a recess 35 which is arranged next to the second end 18 of the fastening element 10. The recess 35 serves to remove the fastening element from the fastening opening 140 in the distribution box 110 by means of a tool, for example a screwdriver.
As can be seen in particular in Figure 2, the fourth bearing face 30 is formed by a plane 37 which is skewed with respect to the extension direction E and is inclined in the direction of the second end 18.
Figures 3 to 16 and 19 to 25 show an installation box 100 which is configured in the form of a distribution box 110. The installation box 100 comprises an interior I and an exterior A. The interior I is separated from the exterior A by at least one wall 102. The installation box 100 comprises an inner side 120, which extends along the wall 102 in the interior I, and an outer side 130, which extends along the wall 102 on the exterior A. The installation box 100 comprises at least one fastening opening 140, wherein the fastening element 10 is able to be plugged at least partially through the fastening opening 140 from the interior I to the exterior A, in order to bring the gripping portion 20a of the fastening element 10 into contact with the rear side 220 of the wall shell 200. The installation box 100 furthermore comprises a bottom 114 and four corners 112. The installation box 100 comprises a peripheral portion 106 which is formed around an opening periphery 108 of the installation box 100 and which bears on a front side of the wall shell 200 in the intended position of the installation box 100 in the wall-shell opening 210.
Preferably, the fastening opening 140 is formed in an approximately rectangular manner.
As can be seen in particular in Figure 5, in a preferred configuration, the installation box 100 comprises four fastening openings 140 which are each arranged next to the corners 112 of the installation box 10 0 .
As Figures 9 to 16 and 19 to 25 illustrate in particular, the installation box 100 comprises at least one stop portion 122 next to the fastening opening 140 on the inner side 120, wherein the stop 22 of the fastening element 10 is configured such that, after the fastening element 10 has been partially passed through the fastening opening 140, the stop 22 is located opposite the stop portion 122, and preferably bears against the stop portion 122. In this way, the stop 22, when interacting with the stop portion 122, prevents the fastening element 10 from being able to be passed fully through the fastening opening 140 from the interior I to the exterior A. In this case, a form fit is produced between the stop 22 and the stop portion 122, said form fit keeping the stop 22 and/or the second end 18 of the fastening element 10 in the interior I .
The installation box 100 furthermore comprises a first bearing region 124 next to the fastening opening 140, said first bearing region 124 being suitable, when interacting with the first bearing portion 24, for forming a hinge point. In this case, the fastening element 10 forms a lever which has a first lever arm that is formed by the gripping arm 20. The gripping arm 20 extends in this case between the first bearing portion 24 and the first end 16. The installation box 100 furthermore comprises a second bearing region 126 next to the fastening opening 140, said second bearing region 126 being able to be brought into contact with the second bearing portion 26 of the fastening element 10 in order to counteract any pivoting movement of the first lever away from the rear side 120 of the wall shell 200. The interaction of the second bearing portion 26 with the second bearing region 126 is visible in particular in Figures 9 to 11, 15 and 19 to 25.
The first bearing region 124 can be formed by an edge of the fastening opening 140. Furthermore, the first bearing region 124 can be formed by a lower edge of the fastening opening 140, which bounds a periphery of the fastening opening 140 that is arranged closest to the box bottom 114.
The second bearing region 126 can be formed by a face which extends approximately parallel to the box bottom 114 and/or extends towards the box bottom 114 in the direction R.
The face which forms the second bearing region 124 can transition into an upper edge of the fastening opening 140 in the direction R, wherein the upper edge is preferably located opposite the lower edge.
According to the first exemplary embodiment, which is reproduced in Figures 1 to 16, the fastening device 1 comprises at least one pivoting element 50 which is configured as a screw element 52. The screw element 52 can be a commercially available screw. The screw element 52 is suitable for being screwed into a thread 150 in the installation box 100. In its intended position, the screw element 52 bears on the third bearing portion 28 in order to exert a force F on the third bearing portion 28. As a result of the force F being exerted, the fastening element 10 is pivoted such that the gripping portion 20a is brought into engagement with the rear side 220 and a retaining force is exerted on the rear side 220 of the wall shell 200. In conjunction with the first bearing portion 24 and the first bearing region 124, the force F also prevents any pivoting of the gripping arm 20 away from the rear side 220.
As can be seen in particular in Figure 12, the fourth bearing portion 30 serves to bear against the outer side 130 of the installation box 100 next to the fastening opening 140. The fifth bearing portion 32 serves to bear against the inner side 120 of the installation box 100 next to the fastening opening 140. According to this configuration, the fourth bearing portion 30 and the fifth bearing portion 32 form a bearing which prevents any pivoting of the fastening element 10 beyond an intended maximum pivoting position .
Figures 6 to 8 illustrate how the fastening element 10 is passed at least partially through the fastening opening 140 from the interior I to the exterior A in order to bring the gripping portion 20a into contact with the rear side 220 of the wall shell 200. In this case, the fastening element 10 is guided through the fastening opening 140, with the first end 16 at the front, in a direction R extending parallel to the box bottom 114. In this case, the first bearing region 124 and the second bearing region 126 can be formed such that the passing through of the fastening element 10 in the direction R causes the gripping portion 20a to move towards the rear side 220 of the wall shell 200. Accordingly, the fastening element 10 is introduced into the fastening opening 140 such that the gripping portion 20a is made to move towards the rear side 220 of the wall shell 200. As a result, the installation box 100 is fixed or pre-fixed in the wall-shell opening 210 in an easy manner. In order to further reinforce the fixing of the installation box 100 in the wall-shell opening 210, it is possible, if required, to pivot the fastening element 10 by means of the screw element 52 such that the force F exerted on the second bearing portion 28 and, as a result, the retaining force P exerted on the rear side 220 by the gripping portion 20a are enhanced. The force F is exerted on the third bearing portion 28 in that the screw element 52 is screwed into the thread 150 in order to transfer the screw element 52 into a movement in translation transversely to the box bottom 114. In this case, the screw element 52 can travel along the third bearing portion 28 from the curved face 27 to the inclined plane 29.
Figures 17 to 25 reproduce the fastening device 1 in the second exemplary embodiment. The fastening device 1 according to the second exemplary embodiment is formed substantially by at least one fastening element 10 which is reproduced in Figures 17 and 18. The fastening device 1 is formed by four fastening elements 10 according to this exemplary embodiment.
The fastening element 10 of the fastening device 1 according to the second exemplary embodiment comprises a gripping arm 20 which is formed substantially by a spring element 21. The spring element 21 can be configured in the form of a bending spring or a leaf spring. According to the second exemplary embodiment, the gripping arm 20 is inclined, in its intended position, towards the rear side 220 with respect to a part of the fastening element 10 which extends between the first bearing portion 24 and the second end 18.
During a first phase of the at least partial passing of the fastening element 10 through the fastening opening 140, the spring element 21 bears against the rear side 220 with its gripping portion 20a. As is shown in particular in Figure 25, the retaining force P which retains the installation box 100 in the wall-shell opening 210 is a restoring force P' caused by a deformation of the spring element 21. A second phase of the partial passing of the fastening element 10 through the fastening opening 140 transfers the fastening element 10 into its intended position, reproduced in Figure 25, in which the first bearing portion 24 bears against the first bearing region 124 and the second bearing portion 26 bears against the second bearing region 126. During the second phase, the retaining force P is continuously increased in that the spring element 21 is deformed. While the gripping portion 20a bears against the rear side 220 of the wall shell 200, the spring element 21 forms, between the first bearing portion 24 and the gripping portion 20a, a load arm of a lever. In the intended position, the part which extends between the first bearing portion 24 and the second end 18 forms a lever arm which prevents the fastening element 10 from being rotated about the first bearing portion 24 such that the gripping arm 20 is moved away from the rear side 220.
The configuration of the fastening element 10 according to the second exemplary embodiment allows the installation box 100 to be fixed rapidly in the wall shell 210 in that the fastening element is passed partially through the fastening opening 140 from the interior I to the exterior A until the stop 22 bears against the stop portion 122. This step is repeated for each of the four fastening elements 10. Further steps in addition thereto are not necessary.
Preferably, the installation box 100 and each fastening element 10 are produced from plastics material.
Of course, the invention is not limited to the embodiments described and illustrated. Amendments, for example to the embodiments of the various components, or replacements with technical equivalents are possible at any time as long as they remain within the scope of the claimed subject matter for which protection is sought.
