[0001] Flat fastening elements for a perforated wall system

[0002] Description

[0003] The present disclosure relates to fastening elements for a pegboard and a pegboard system comprising such fastening elements. In particular, the present disclosure relates to flat fastening elements such that only a minimal gap remains between a fastening element and an object to be fastened to the pegboard.

[0004] It's already common practice to use pegboards in vans and motorhomes to secure items. These pegboards generally have openings into which so-called clips can be inserted and secured. However, in vans and motorhomes, the available space is very limited, so it's advantageous if items such as motorhome furniture modules can be attached as close to the pegboard as possible to maximize the remaining space in the motorhome.

[0005] It is an object of the present disclosure to provide fastening elements for a perforated wall and a perforated wall system comprising such fastening elements that enable objects to be fastened as close as possible to a perforated wall. In particular, it is an object of the present disclosure to minimize a gap or distance between a perforated wall and an object fastened to the perforated wall.

[0006] This object is achieved by the subject matter of the independent claims. Advantageous embodiments are specified in the subclaims.

[0007] According to a first independent aspect of the present disclosure, a fastening element for fastening an object to a perforated wall is provided. The fastening element comprises a base body that can be inserted into a hole in a perforated wall, the base body having a front side and a rear side; and a rotary latch that is rotatably mounted on the rear side of the base body about a rotation axis, the rotary latch being rotatable between a first position and a second position, the base body being insertable into the hole in the perforated wall when the rotary latch is in the first position, and the rotary latch resting on a surrounding area of ​​the hole on a rear side of the perforated wall when the rotary latch is in the second position in order to fix the fastening element in the hole in the perforated wall.The rotary latch comprises adjusting means with which the rotary latch can be rotated, wherein the base body has an opening in its front side so that the adjusting means of the rotary latch are accessible from the front side of the base body.

[0008] According to the first independent aspect of the present disclosure, a rotary latch is provided that is adjustable to rest on a region surrounding the hole on a rear side of the hole wall to secure the fastener in the hole. This allows the fastener to protrude only minimally from the front side of the hole wall, thus minimizing the gap between the hole wall and an object attached to the hole wall. In other words, this enables objects to be attached as close as possible to the hole wall.

[0009] In one design variant, the base body can be inserted into the hole of the perforated wall in a form-fitting manner.

[0010] In one design variant, the first position of the rotary latch is called the open position and the second position of the rotary latch is called the closed position.

[0011] In one embodiment, the rear side of the base body, in particular a surface thereof, is aligned substantially parallel to the front side and / or rear side of the perforated wall when the fastening element is inserted into the hole of the perforated wall.

[0012] In one embodiment, the front side of the base body, in particular a surface thereof, is aligned substantially parallel to the front side and / or back side of the perforated wall when the fastening element is inserted into the hole of the perforated wall.

[0013] In one embodiment, the rotary latch is wing-shaped. In one embodiment, the rotary latch can be rotated between 60° and 120° between the first position and the second position. In particular, the rotary latch can be rotated by 90° between the first position and the second position.

[0014] In one design variant, a rotation plane of the rotary latch is essentially parallel to the back of the base body.

[0015] In one embodiment, the rotation axis of the rotary latch is essentially perpendicular to the front and / or back of the base body.

[0016] In one embodiment, the rotary latch has a rotary latch length and a rotary latch width, with the rotary latch length being greater than the rotary latch width.

[0017] In one embodiment, the hole in the perforated wall has a hole length and a hole width. In some embodiments, the hole length can be greater than the hole width.

[0018] In one design variant, the length of the locking latch is equal to or less than the hole length. Furthermore, the width of the locking latch can be equal to or less than the hole width. The length of the locking latch can be greater than the hole width. This allows the fastener or locking latch to be inserted into the hole in the perforated panel when the locking latch is in the first position. Furthermore, the locking latch rests on the area surrounding the hole on the back of the perforated panel when the locking latch is turned to the second position.

[0019] In one embodiment, the base body has a recess on its rear side. The rotary latch can have a projection, with the projection of the rotary latch being inserted into the recess of the base body, so that the rotary latch is rotatably mounted in the recess of the base body. This allows a rotary bearing to be provided in a simple manner.

[0020] In one embodiment, the projection is arranged essentially centrally on the rotary latch.

[0021] In one design variant, the projection of the rotary latch is movable along a longitudinal axis of the projection and / or a longitudinal axis of the recess within the recess. This allows the rotary latch to rotate despite varying material thicknesses of the hole wall, since the distance between the rotary latch and the base body parallel to the rotary latch's axis of rotation is variable within certain limits.

[0022] In one embodiment, the projection of the rotary latch has a circumferential groove, wherein a stop is formed on an inner side of the recess of the base body, which stop is arranged in the circumferential groove of the projection of the rotary latch in order to limit a rotational movement of the rotary latch.

[0023] In one embodiment, the stop is a projection and / or an end stop on the inside of the recess of the base body.

[0024] In one design variant, the length of the circumferential groove is smaller than the circumference of the projection of the rotary latch. This allows the rotary movement of the rotary latch to be limited to less than 360°.

[0025] In one design variant, the length of the circumferential groove corresponds to a quarter of the circumference of the projection of the rotary latch. This allows the rotary latch to be limited to less than 90°.

[0026] In one design variant, the width of the circumferential groove is greater than the width of the stop in the recess of the base body. This allows the distance between the rotary latch and the base body to be varied within certain limits parallel to the rotary latch's rotation axis, allowing the rotary latch to rotate even with varying material thicknesses of the perforated wall.

[0027] In one embodiment, one side of the rotary latch, opposite the rear side of the base body, has at least one bevel. In particular, the bevel can slope away from the rotation axis, allowing the rotary latch to be rotated from the first position to the second position without jamming. This allows for thickness tolerances of the perforated wall to be compensated.

[0028] In one embodiment, the adjusting means are arranged at an end of the projection facing the base body. The opening in the front of the base body can be opposite the end of the projection, so that the adjusting means are accessible from the front, even when the fastening element is inserted into the hole in the perforated wall. In one embodiment, the adjusting means comprise or provide an engagement. The engagement enables the rotary latch to be rotated through the opening in the front of the base body, for example, using a tool such as a screwdriver.

[0029] In one design variant, the engagement is designed as a slot, square, or hexagon. This allows the fastener to be tightened and loosened using standard tools.

[0030] In one embodiment, the adjusting means incorporate a fastening thread designed for attaching objects. In particular, objects can be attached to the fastening element with a stable and reliable screw connection.

[0031] In one embodiment, a longitudinal axis of the fastening thread is substantially parallel to a longitudinal axis of the projection of the rotary latch and / or substantially parallel to a longitudinal axis of the recess of the base body and / or substantially parallel to the rotational axis of the rotary latch.

[0032] In one embodiment, the adjusting means comprise an indicating recess and / or an indicating projection which are visible through the opening in the front of the base body, wherein the indicating recess and / or the indicating projection indicate a rotational position of the rotary latch with respect to the base body.

[0033] In one embodiment, the indicator recess and / or the indicator projection are located at the end of the projection opposite the base body or the opening in the base body. This ensures excellent visibility of the indicator recess and / or the indicator projection.

[0034] In one embodiment, the projection and the adjusting means of the rotary latch are formed in one piece.

[0035] In one embodiment, the base body of the fastening element of the first embodiment and / or the second embodiment comprises a side surface that connects the front and rear sides of the base body, wherein a shape of the side surface substantially corresponds to the shape of the hole in the hole wall. The hole and thus the side surface of the base body can be formed, for example, as a rectangle or elongated hole, in particular with rounded edges. In some embodiments, the side surface of the base body can be conical, so that any inaccuracies in the holes in the hole wall are compensated for.

[0036] In one embodiment variant, the main body of the fastening element of the first embodiment and / or the second embodiment comprises a projection portion on its front side, wherein the projection portion lies on or on a surrounding area of ​​the hole on the front side of the hole wall when the fastening element is inserted into the hole.

[0037] According to a second independent aspect of the present disclosure, which can be combined at least partially with the first independent aspect, a fastening element for fastening an object to a perforated wall is provided.The fastening element comprises a base body which can be inserted into a hole in a perforated wall, wherein the base body has a front side and a rear side; at least two folding elements on the rear side of the base body, wherein the at least two folding elements are each movable between a first position and a second position, wherein the base body can be inserted into the hole in the perforated wall when the at least two folding elements are in the respective first position, and wherein the at least two folding elements rest against a surrounding area of ​​the hole on a rear side of the perforated wall when the at least two folding elements are in the respective second position in order to fix the fastening element in the hole in the perforated wall; and adjusting means on the front side of the base body, wherein the adjusting means are configured to move the at least two folding elements at least from the first position into the second position.

[0038] According to the second independent aspect of the present disclosure, folding elements are provided that are adjustable to engage a region surrounding the hole on a rear side of the hole wall to secure the fastening element in the hole. This allows the fastening element to protrude only minimally from the front side of the hole wall, thus minimizing the gap between the hole wall and an object fastened to the hole wall. In other words, fastening objects as close as possible to the hole wall is enabled.

[0039] In one embodiment, the base body can be inserted into the hole in the perforated wall in a substantially form-fitting manner. In one embodiment, the first position of the at least two folding elements is referred to as the open position, and the second position of the at least two folding elements is referred to as the closed position.

[0040] In one embodiment, the rear side of the base body, in particular a surface thereof, is aligned substantially parallel to the front side and / or rear side of the perforated wall when the fastening element is inserted into the hole of the perforated wall.

[0041] In one embodiment, the front side of the base body, in particular a surface thereof, is aligned substantially parallel to the front side and / or back side of the perforated wall when the fastening element is inserted into the hole of the perforated wall.

[0042] In one embodiment, the at least two folding elements extend further in a direction parallel to the rear side of the base body in the second position than in the first position. In particular, the extension of the at least two folding elements parallel to the rear side of the base body in the first position can be smaller than an extension, such as a width, of the hole in the perforated wall. This allows the fastening element to be inserted into the hole. Similarly, the extension of the at least two folding elements parallel to the rear side of the base body in the second position can be greater than an extension, such as a width, of the hole in the perforated wall. This allows the fastening element to be fastened or locked in the hole after being inserted into the hole.

[0043] In one embodiment, the at least two folding elements extend further in a direction perpendicular to the rear side of the base body in the first position than in the second position.

[0044] In one embodiment, the at least two folding elements extend substantially parallel to the rear side of the perforated wall in the second position. In particular, the at least two folding elements can lie substantially flat against the rear side of the perforated wall in the second position. Such a wide contact surface enables reliable and stable fixation of the fastening element in the hole of the perforated wall. In one embodiment, the at least two folding elements are mounted on the rear side of the base body so they can rotate about a respective rotation axis. This allows the fastening element to be fastened and optionally released again using a simple rotating mechanism.

[0045] In one embodiment, the at least two folding elements can be rotated between the first position and the second position by rotating about the respective axis of rotation. In particular, the at least two folding elements can be rotated from the first position to the second position by rotating about the respective axis of rotation in order to secure the fastening element. Similarly, the at least two folding elements can be rotated from the second position to the first position by rotating about the respective axis of rotation in order to release the fastening element.

[0046] In one embodiment, the pivot axis is located at the center of the folding element. This allows the folding element to be rotated into the second position relative to the rear of the base body to secure the fastening element. Similarly, the folding element can be rotated into the first position relative to the rear of the base body to release the fastening element.

[0047] In one embodiment, the axes of rotation of at least two folding elements are essentially parallel to the rear side of the base body.

[0048] In one embodiment, the axes of rotation of the at least two folding elements are essentially parallel to each other.

[0049] In one embodiment, the at least two folding elements comprise a first folding element and a second folding element. However, the present disclosure is not limited thereto, and three or more folding elements may be provided.

[0050] In one embodiment, the first folding element is mounted on the rear side of the base body for rotation about a first axis of rotation. The second folding element can be mounted on the rear side of the base body for rotation about a second axis of rotation.

[0051] In one embodiment, the first rotation axis and the second rotation axis are substantially parallel. In one embodiment, the first folding element is movable from the first position to the second position by rotation in a first direction of rotation.

[0052] In one embodiment, the second folding element is movable from the first position to the second position by rotation in a second direction of rotation.

[0053] In one embodiment, the first folding element can be moved from the second position to the first position by rotating in the second direction of rotation.

[0054] In one embodiment, the second folding element can be moved from the second position to the first position by rotating in the first direction of rotation.

[0055] In one design variant, the first and second directions of rotation are opposite directions. This allows the fastener to be attached to opposite sides of the hole in the perforated panel, ensuring reliable and stable fixation of the fastener to the perforated panel, even when forces act on the fastener from different directions.

[0056] In one embodiment, the adjusting means have a first end at the front of the base body and a second end at the rear of the base body, wherein the second end has a stop region that abuts against the at least two folding elements in order to move the at least two folding elements from the first position to the second position by applying a force. Thus, by displacing the adjusting means between the front of the base body and the rear of the base body, a force can be exerted on the at least two folding elements in order to move the at least two folding elements from the first position to the second position.

[0057] In one embodiment, the stop area of ​​the adjusting means is beveled and / or conical. The stop area of ​​the adjusting means can abut against a correspondingly designed stop area of ​​the at least two folding elements to enable stable force transmission from the adjusting means to the at least two folding elements.

[0058] In one embodiment, the base body comprises a through-hole between its front and rear sides. In one embodiment, the through-hole extends substantially perpendicular to the front of the base body and / or substantially perpendicular to the rear of the base body.

[0059] In one embodiment, the adjusting means can be inserted into the through-hole and can be moved therein along a longitudinal axis of the through-hole in order to move the at least two folding elements from the first position into the second position.

[0060] In one embodiment, an opening of the through-hole is arranged on the rear side of the base body between the first rotational axis of the first folding element and the second rotational axis of the second folding element. This allows the actuating means emerging from the opening of the through-hole to bear simultaneously and symmetrically against the at least two folding elements in order to move the at least two folding elements from the first position to the second position by applying a force.

[0061] In one design variant, the through hole of the base body is a threaded hole.

[0062] In one variant, the adjusting means include, or are, a screw that can be screwed into and unscrewed from the threaded hole in the base body. This allows the fastening element to be tightened and loosened with a simple twisting motion.

[0063] In one design variant, a recess is formed on or in the first end of the adjusting means or screw, allowing the screw to be screwed into the threaded hole. The recess can be designed, for example, as a slot, square, or hexagon. This makes it possible to tighten and loosen the fastening element using common tools.

[0064] In one embodiment, the adjusting means incorporate a fastening thread designed for attaching objects. In particular, objects can be attached to the fastening element with a stable and reliable screw connection.

[0065] In one embodiment, the through hole of the base body and the fastening thread of the adjusting means extend essentially parallel. In one embodiment, the through hole of the base body and the fastening thread of the adjusting means are essentially concentric.

[0066] According to a further independent aspect of the present disclosure, a perforated wall system is provided, comprising a perforated wall and one or more of the fastening means described in this document.

[0067] The attached figures illustrate possible embodiments of the proposed solution.

[0068] Here we show:

[0079] Figures 9A-9C show various views of the fastening element according to the second embodiment of the present disclosure.

[0080] In the following, unless otherwise stated, the same reference symbols are used for identical and equivalent elements.

[0081] Figure 1 shows a perspective front view of a perforated wall 1 with fastening elements 30, 40 according to embodiments of the present disclosure. Figure 2 shows a top view of the perforated wall 1 with fastening elements 30, 40. Figure 3 shows a top view of the perforated wall 1 with fastening elements 30, 40 (left) and a sectional view thereof (right). Figure 4 shows a perspective rear view of the perforated wall 1 with fastening elements 30, 40.

[0082] The perforated wall 1 comprises a plurality of openings or holes 2 into which fastening elements 30, 40 can be inserted and locked, for example, to fasten objects to the perforated wall 1. In particular, the perforated wall 1 has a perforated wall front 1a and a perforated wall rear 1b, wherein a fastening element 30, 40 can be inserted from the perforated wall front 1a into a hole 2 (Figure 1) and fixed there by a locking mechanism (Figures 3A-4B and 4).

[0083] According to embodiments of the present disclosure, two locking mechanisms are provided: a two-flap fastener 30 and a twist-lock fastener 40. The two-flap fastener 30 is described with reference to Figures 5A-5C and 6A-6E, and the twist-lock fastener 40 is described with reference to Figures 7A-9C.

[0084] The perforated wall 1 can be used in means of transportation to attach objects to it, such as furniture modules of a mobile home. The perforated wall 1 can be used as wall paneling and / or floor and / or ceiling paneling. The term "means of transportation" typically includes transport vehicles such as trucks, buses, mobile homes, caravans, vans, etc., which are used to transport people, goods, etc. However, the present disclosure is not limited thereto, and the term "means of transportation" can also include, for example, ships and / or train wagons.

[0085] Figures 5A-5C and 6A-6E show various views of a fastener 30 according to a first embodiment of the present disclosure.

[0086] The fastening element 30 comprises a base body 32 which can be inserted into a hole 2 of a perforated wall 1, the base body 32 having a front side 32a and a back side 32b; at least two folding elements 34a, 34b on the rear side 32b of the base body 32, wherein the at least two folding elements 34a, 34b are each movable between a first position (Figures 5A-5C) and a second position (Figures 6A-6E), wherein the base body 32 can be inserted into the hole 2 of the perforated wall 1 when the at least two folding elements 34a, 34b are in the respective first position, and wherein the at least two folding elements 34a, 34b rest against a surrounding area of ​​the hole 1 on a rear side 1b of the perforated wall 1 when the at least two folding elements 34a, 34b are in the respective second position in order to fix the fastening element 30 in the hole 2 of the perforated wall 1;and adjusting means 36 on the front side 32a of the base body 32, wherein the adjusting means 36 are configured to move the at least two folding elements 34a, 34b at least from the first position to the second position.;

[0087] This allows the fastening element 30 to protrude only minimally from the front side 1a of the perforated wall 1, as shown in Figures 3A and 3B, so that a gap between the perforated wall 1 and an object (not shown) attached to the perforated wall 1 is minimized. In other words, attachment of objects as close as possible to the perforated wall 1 is enabled.

[0088] In one embodiment, the base body 32 comprises a side surface 32c that connects the front side 32a and the rear side 32b of the base body 32, and wherein a shape of the side surface 26c substantially corresponds to the shape of the hole 2 of the perforated wall 1. The hole 2 and thus the side surface 32c of the base body 32 can be formed, for example, as a rectangle or elongated hole, in particular with rounded edges. In some embodiments, the side surface 32c of the base body 32 can be slightly conical, so that any inaccuracies in the holes 2 of the perforated wall 1 are compensated for.

[0089] In some embodiments, the base body 32 comprises a protrusion portion 32e on the front side 32a, wherein the protrusion portion 32a abuts against a surrounding area of ​​the hole 2 on the front side 1a of the hole wall 1 when the fastening element 30 is inserted into the hole 2.

[0090] Typically, the rear side 32b of the base body 32, in particular a surface thereof, is oriented substantially parallel to the front side 1a and / or rear side 1b of the perforated wall 1 when the fastening element 30 is inserted into the hole 2 of the perforated wall 1. Additionally or alternatively, the front side 32a of the base body 32, in particular a surface thereof, can be oriented substantially parallel to the front side 1a and / or rear side 1b of the perforated wall 1 when the fastening element 30 is inserted into the hole 2 of the perforated wall 1.

[0091] The term "parallel" refers to a substantially parallel alignment, e.g., of surfaces or axes. A deviation of a few degrees, e.g., up to 5° or even up to 10°, from exact parallel alignment is still considered a "substantially parallel alignment." Similarly, the term "perpendicular" refers to a substantially perpendicular alignment, e.g., of surfaces or axes. A deviation of a few degrees, e.g., up to 5° or even up to 10°, from exact perpendicular alignment is still considered a "substantially perpendicular alignment."

[0092] In some embodiments, the at least two folding elements 34a, 34b extend further in a direction parallel to the rear side 32b of the base body 32 in the second position than in the first position, as can be seen from a comparison of the respective Figures 5C and 6E. In particular, the extension of the at least two folding elements 34a, 34b parallel to the rear side 32b of the base body 32 in the first position can be smaller than an extension, such as a width, of the hole 2 in the perforated wall 1. As a result, the fastening element 30 can be inserted into the hole 2. Similarly, the extension of the at least two folding elements 34a, 34b parallel to the rear side 32b of the base body 32 in the second position can be greater than an extension, such as a width, of the hole 2 in the perforated wall 1. As a result, the fastening element 30 can be fastened or locked in the hole 2 after being inserted into the hole 2.In one embodiment, the at least two folding elements 34a, 34b extend in the second position substantially parallel to the rear side 1b of the perforated wall 1, as shown in Figures 3A and 3B. In particular, the at least two folding elements 34a, 34b can rest substantially flat against the rear side 1b of the perforated wall 1 in the second position. Such a wide contact surface enables a reliable and stable fixation of the fastening element 30 in the hole 2 of the perforated wall 1.

[0093] In some embodiments, the at least two folding elements 34a, 34b are mounted rotatably about a respective rotation axis DA1, DA2 on the rear side 32b of the base body 32, for example, by means of corresponding hinges. Thus, the fastening element 30 can be attached and optionally released again using a simple rotating mechanism.

[0094] In one embodiment, the at least two folding elements 34a, 34b can be rotated between the first position and the second position by rotating about the respective rotational axis DA1, DA2. In particular, the at least two folding elements 34a, 34b can be rotated from the first position to the second position by rotating about the respective rotational axis DA1, DA2 in order to fix the fastening element 30. Similarly, the at least two folding elements 34a, 34b can be rotated from the second position to the first position by rotating about the respective rotational axis DA1, DA2 in order to release the fastening element 30.

[0095] In one embodiment, the rotation axis is provided in the center of the folding element 30. Thus, the folding element 34a, 34b can be rotated into the second position relative to the rear side 32b of the base body 32 to secure the fastening element 30. Similarly, the folding element 34a, 34b can be rotated into the first position relative to the rear side 32b of the base body 32 to release the fastening element 30.

[0096] In some embodiments, the rotation axes DA1, DA2 of the at least two folding elements 34a, 34b are substantially parallel to the rear side 32b of the base body 32 and / or substantially parallel to each other.

[0097] As shown in the example of Figures 5A-5C and 6A-6E, the at least two folding elements 34a, 34b can comprise a first folding element 34a and a second folding element 34b. The first folding element 34a can be rotatably mounted about a first rotation axis DA1 on the rear side 32b of the base body 32, for example, by a first hinge. The second folding element 34b can be rotatably mounted about a second rotation axis DA2 on the rear side 32b of the base body 32, for example, by a second hinge.

[0098] The first folding element 34a can be moved from the first position to the second position by rotation in a first rotation direction, and the second folding element 34b can be moved from the first position to the second position by rotation in a second rotation direction. The first rotation direction and the second rotation direction can be opposite rotation directions. Thus, the fastening element 30 can be fastened on opposite sides of the hole 2 of the perforated wall 1, enabling a reliable and stable fixation of the fastening element 30 to the perforated wall 1, even when forces act on the fastening element 30 from different directions.

[0099] In one embodiment, the adjusting means 36 have a first end 36a on the front side 32a of the base body 32 and a second end 36b opposite the first end 36a on the rear side 32b of the base body 32. The second end 36b can have a bevelled and / or conical stop region 36c, for example, which abuts against the at least two folding elements 34a, 34b in order to move the at least two folding elements 34a, 34b from the first position into the second position by applying a force. Thus, by displacing the adjusting means 36 between the front side 32a of the base body 32 and the rear side 32b of the base body 32, a force can be exerted on the at least two folding elements 34a, 34b in order to move the at least two folding elements 34a, 34b from the first position into the second position.

[0100] In some embodiments, the base body 32 includes a through-hole 32d between its front side 32a and its back side 32b. The through-hole 32d may extend substantially perpendicular to the front side 32a of the base body 32 and / or substantially perpendicular to the back side 32b of the base body 32.

[0101] In one embodiment, the adjusting means 36 can be inserted into the through-hole 32d and are movable therein along a longitudinal axis of the through-hole 32d in order to move the at least two folding elements 34a, 34b from the first position to the second position. An opening of the through-hole 32d can be arranged on the rear side 32b of the base body 32 between the first rotational axis DA1 of the first folding element 34a and the second rotational axis DA2 of the second folding element 34b. Thus, the adjusting means 36 emerging from the opening of the through-hole 32d can bear simultaneously and symmetrically against the at least two folding elements 34a, 34b in order to move the at least two folding elements 34a, 34b from the first position to the second position by applying a force.

[0102] In some embodiments, the through-hole 32d may be a threaded bore. In this case, the adjusting means 36 may comprise or be a screw that can be screwed into and unscrewed from the threaded bore. Thus, the fastening element 30 can be fastened and released again by a simple turning movement.

[0103] An engagement 36e can be formed on or in the first end 36a of the adjusting means 36 or the screw, which allows the screw to be screwed into the threaded bore of the base body 32. The engagement 36e can be designed, for example, as a slot, square, or hexagon. This makes it possible to fix and release the fastening element 30 using common tools.

[0104] In some embodiments, a fastening thread 36d can be formed in the adjusting means 36, which is configured for fastening objects. In particular, objects can be fastened to the fastening element 30 with a stable and reliable screw connection.

[0105] The through hole 32d of the base body 32 and the fastening thread 36d of the adjusting means 36 can be formed substantially parallel and / or substantially concentric.

[0106] Figures 7A to 9C show various views of a fastener 40 according to a second embodiment of the present disclosure.

[0107] The fastening element 40 comprises a base body 42 which can be inserted into a hole 2 of a perforated wall 2, wherein the base body 42 has a front side 42a and a rear side 42b; and a rotary latch 44 which is rotatably mounted on the rear side 42b of the base body 42 about a rotation axis DA, wherein the rotary latch 44 is rotatable between a first position (Figures 8A-8C) and a second position (Figures 9A-9C), wherein the base body 42 can be inserted into the hole 2 of the perforated wall 1 when the rotary latch 44 is in the first position, and wherein the rotary latch 44 rests on a surrounding area of ​​the hole 2 on a rear side 1b of the perforated wall 1 when the rotary latch 44 is in the second position in order to fix the fastening element 40 in the hole 2 of the perforated wall 1.The rotary latch 44 comprises adjusting means 44a with which the rotary latch 44 can be rotated, wherein the base body 42 has an opening 42d in its front side 42a, so that the adjusting means 44a of the rotary latch 44 are accessible from the front side 42a of the base body 42.

[0108] This allows the fastening element 40 to protrude only minimally from the front side 1a of the perforated wall 1, as shown in Figures 3A and 3B, so that a gap between the perforated wall 1 and an object (not shown) attached to the perforated wall 1 is minimized. In other words, attachment of objects as close as possible to the perforated wall 1 is enabled.

[0109] In one embodiment, the base body 42 comprises a side surface 42c that connects the front side 42a and the rear side 42b of the base body 42, and wherein a shape of the side surface 42c substantially corresponds to a shape of the hole 2 of the perforated wall 1. The hole 2 and thus the side surface 42c of the base body 42 can be formed, for example, as a rectangle or elongated hole, in particular with rounded edges. In some embodiments, the side surface 42c of the base body 42 can be slightly conical, so that any inaccuracies in the holes 2 of the perforated wall 1 are compensated for.

[0110] In some embodiments, the base body 42 includes a protrusion portion 42g on the front side 42a, wherein the protrusion portion 42a abuts against a surrounding area of ​​the hole 2 on the front side 1a of the hole wall 1 when the fastening element 40 is inserted into the hole 2.

[0111] Typically, the rear side 42b of the base body 42, in particular a surface thereof, is aligned substantially parallel to the front side 1a and / or rear side 1b of the perforated wall 1 when the fastening element 40 is inserted into the hole 2 of the perforated wall 1. Additionally or alternatively, the front side 42a of the base body 42, in particular a surface thereof, can be aligned substantially parallel to the front side 1a and / or rear side 1b of the perforated wall 1 when the fastening element 40 is inserted into the hole 2 of the perforated wall 1. The term "parallel" refers to a substantially parallel alignment, e.g., of surfaces or axes, whereby a deviation of a few degrees, e.g., up to 5° or even up to 10°, from an exact parallel alignment is still considered a "substantially parallel alignment." Similarly, the term "perpendicular" refers to a substantially perpendicular alignment, e.g.,of surfaces or axes, whereby a deviation of a few degrees, e.g. up to 5° or even up to 10°, from an exact perpendicular orientation is still considered a 'substantially perpendicular orientation'.

[0112] In one design variant, the rotary latch 44 is wing-shaped.

[0113] Typically, the rotary latch 44 is rotatable within a range of 60° to 120° between the first position and the second position. In particular, the rotary latch 44 can be rotatable by 90° between the first position and the second position.

[0114] In some embodiments, a rotary latch length is equal to or less than a hole length. Furthermore, a rotary latch width can be equal to or less than a hole width. The rotary latch length can be greater than the hole width. This allows the fastening element 40 or the rotary latch 44 to be inserted into the hole 2 of the perforated panel 1 when the rotary latch 44 is in the first position, as shown in Figure 4. Furthermore, the rotary latch rests on the area surrounding the hole on the rear side of the perforated panel 2 when the rotary latch 44 is rotated to the second position, as also shown in Figure 4.

[0115] In some embodiments, the base body 42 has a recess 42e on its rear side 42b. The rotary latch 44 may have a projection 44b, wherein the projection 44b of the rotary latch 44 is inserted or insertable into the recess 42e of the base body 44, so that the rotary latch 44 is rotatably mounted in the recess 42e of the base body 42. This allows a rotary bearing to be provided in a simple manner.

[0116] The projection 44b can be arranged substantially centrally on the rotary latch 44.

[0117] In some embodiments, the projection 44b of the rotary latch 44 is movable along a longitudinal axis of the projection 44b and / or a longitudinal axis of the recess 42e in the recess 42e and / or substantially parallel to the rotation axis DA. This allows the rotary latch 44 to rotate despite varying material thicknesses of the perforated wall 2, since the distance d (Figures 8A-8C) between the rotary latch 44 and the base body 42 is variable within certain limits parallel to the rotation axis DA of the rotary latch 44.

[0118] The projection 44b of the rotary latch 44 may have a circumferential groove 44c, wherein a stop 42f is formed on an inner side of the recess 42e of the base body 42. The stop 42f is arranged in the circumferential groove 44c of the projection 44b of the rotary latch 44 to limit a rotational movement of the rotary latch 44. The stop 42f may be a projection and / or an end stop and / or a pin on the inner side of the recess 42e of the base body 42.

[0119] In one embodiment, the length of the circumferential groove 44c is smaller than the circumference of the projection 44b of the rotary latch 44. This allows the rotary movement of the rotary latch 44 to be limited to less than 360°. For example, the length of the circumferential groove 44c corresponds to a quarter of the circumference of the projection 44b of the rotary latch 44. This allows the rotary movement of the rotary latch 44 to be limited to 90° or less.

[0120] In some embodiments, a width of the circumferential groove 44c is greater than a width of the stop 42f in the recess 42e of the base body 42. As a result, the distance d between the rotary latch 44 and the base body 42 parallel to the rotation axis DA of the rotary latch 44 is variable within certain limits, so that the rotary latch 44 can still rotate with different material thicknesses of the perforated wall 1.

[0121] In one embodiment, one side of the rotary latch 44, which is opposite the rear side 42b of the base body 42b, has at least one bevel 44d. In particular, the bevel 44d can slope in a direction away from the rotation axis DA, so that the rotary latch 44 can be rotated from the first position to the second position without blocking. This allows thickness tolerances of the perforated wall 1 to be compensated.

[0122] In some embodiments, the adjusting means 44a are arranged at an end of the projection 44b facing the base body 42. The opening 42d in the front side 42a of the base body 42 can be opposite the end of the projection 44b, so that the adjusting means 44a are accessible from the front, even when the fastening element 40 is inserted into the hole 2 of the perforated wall 1. The adjusting means 44a can comprise an engagement or provide the engagement. The engagement enables the rotary latch 44 to be rotated through the opening 42d in the front side 42a of the base body 42, for example, using a tool such as a screwdriver. The engagement can be designed as a slot, square, or hexagon. This makes it possible to fix and release the fastening element 40 using common tools.

[0123] In one embodiment, a fastening thread 44e is formed in the adjusting means 44a, which is designed for fastening objects. In particular, objects can be fastened to the fastening element 40 with a stable and reliable screw connection. The fastening thread 44e can be accessible through the opening 42d in the front side 42a of the base body 42.

[0124] In some embodiments, the actuating means 44a comprise an indicator recess 44f (e.g., a groove in Figures 9A-9C) and / or an indicator projection visible through the opening 42d in the front side 42a of the base body 42, wherein the indicator recess 44f and / or the indicator projection indicate a rotational position of the rotary latch 44 relative to the base body 42. For example, a vertical groove may indicate the "insertion" and "removal" positions of the fastener 40, and a horizontal groove may indicate the locked position.

[0125] In one embodiment, the display recess 44f and / or the display projection are arranged at the end of the projection 44b, which is opposite the base body 42 or the opening 42d in the base body 42. This ensures excellent visibility of the display recess 44f and / or the display projection.
