Description

[0001] Locking of a mounting arrangement for mounting electrical modules The present invention relates to a mounting arrangement for mounting at least two electrical modules that can be arranged one above the other in tiers, wherein a first electrical module can be arranged in a first mounting level on a first support, and wherein a second electrical module can be arranged in a second mounting level arranged above the first mounting level on a second support. Furthermore, the invention relates to a holder comprising a mounting arrangement according to the invention. More specifically, the invention relates to an improvement in the placement of functional modules, preferably electrical or electronic functional modules. These are often mounted on supports designed as mounting rails, which allow the installation of a large number of functional modules arranged next to one another. The functional modules are connected in terms of signals, as a rule via wiring, as required.Furthermore, the mounting rails with the mounted functional modules can be installed in control cabinets of limited size, so that the most compact arrangement of the functional modules on the mounting rails is desired. For this purpose, a mounting arrangement for mounting at least two functional modules that can be arranged one above the other in tiers is selected, known in technical terms as a second-level board installation (SLBI). The mounting arrangement is configured such that a first functional module can be arranged in a first mounting level on a mounting rail, next to which a movable or stationary support is arranged. A second functional module is arranged in a second mounting level arranged above the first mounting level on a mounting rail, which in turn can be arranged on a pivoting support. The pivoting support, in turn, is attached to the stationary support.However, in the known solutions, the pivoting support can spring back when opened, disrupting work on the lower functional module and, alternatively or additionally, on the upper functional module. The invention is based on the object of providing a device (mounting arrangement) for electrical modules that enables simple and safe assembly and maintenance of the electrical modules. Furthermore, the invention is based on the object of providing a corresponding holder comprising such a device. This object is achieved by a device for the assembly of at least two electrical modules that can be arranged one above the other in tiers, having the features of patent claim 1.The device according to the invention for locking a movable element to a support element according to a first aspect of the invention is configured such that the support element or the movable element has at least one locking means or at least one locking element. The at least one locking means of the support element and alternatively or additionally the at least one locking means of the movable element are locked to a locking element of the movable element and alternatively or additionally to a locking element of the support element. The locking is carried out by rotation and alternatively or additionally by displacement of the movable element relative to the support element. In addition to a locking position formed by the locking, the support element and the movable element have a further operating position comprising a locking.In the locking position and alternatively or additionally in the operating position, at least one stop and optionally another stop limit the movement of the support element and the movable element relative to each other in the direction of rotation and alternatively or additionally in the direction of displacement. Locking a movable element to a support element is a fixation of the movable element to the support element. This fixation is designed as a positive connection that withstands the forces acting on the movable element and the support element that typically occur during operation and during maintenance or assembly. At the same time, the locking can be changed by an operator without additional tools by overcoming the holding force of the positive connection, thus changing the relative position of the movable element and the support element.The movement of the movable element and the support element relative to each other is structurally restricted such that the locking means and locking element arranged on the movable element and the support element form a positive connection when locked. A support element can be arranged on a first side of an electrical module in a first mounting plane on a carrier (also called a holding rail or support rail). On a second side of the electrical module, a further support element can be arranged axially spaced from the support element. The further support element can also be arranged on the carrier. A further electrical module can be arranged on a further carrier in a second mounting plane arranged above the first mounting plane. The further carrier can in turn be arranged on a movable element connected to the support element in conjunction with a further movable element connected to the further support element.The movable element is movably mounted on the support element. The movement can be performed as a rotation and, alternatively or additionally, as a displacement of the movable element relative to the support element. Preferably, the movable element and the support element can be locked together, with at least two locking positions being provided. This includes a locking position for assembly or maintenance (also called the assembly position) and a locking position for operation (operating position) for the modules that can be arranged on the support rail and on the movable element. The assembly position can be designed to support assembly or wiring or other commissioning of the module arranged on the support rail. The operating position can result in a compact arrangement of the modules. A stop limits the relative movement of the support element and the movable element to one another.This can be the case both in the direction of rotation and, alternatively or additionally, in the direction of displacement. A stop can be designed as a structural feature of the movable element and, alternatively or additionally, of the support element, and can consist of the respective material of the movable element or the support element. It can also be manufactured separately and then arranged on the movable element and, additionally or alternatively, on the support element. Locking means and, alternatively or additionally, locking elements can bear against the stop to limit the relative mobility of the support element and the movable element. Alternatively, a further stop and, optionally, a third stop on the support element or on the movable element, with the stop on the movable element or support element, can limit the relative movement of the support element and the movable element.This advantageously allows improved pivoting and, alternatively or additionally, improved displacement of the movable element to be achieved, since the relative movement of the locking element and the support element to one another is limited. This avoids, for example, damage to electrical modules arranged on the device or neighboring devices that could result from excessive pivoting or displacement. Further advantageous embodiments of the invention are specified in the dependent claims. The features listed individually in the dependent claims can be combined with one another in a technologically expedient manner and can define further embodiments of the invention. Furthermore, the features specified in the claims are further specified and explained in the description, wherein further preferred embodiments of the invention are presented.According to one embodiment of the invention, the locking mechanism can be designed such that the support element and the movable element are temporarily locked together, i.e., as long as the assembly or maintenance process requires them. Optionally, locking into the locking position can be assisted by a spring element, which, in the operating position, exerts a force on the movable element in the direction of the locking position. A temporary locking of the support element and movable element can be designed as a locking mechanism, see above. The positive connection between the support element and the movable element is sufficient to securely withstand the forces of the masses of the (electrical) modules that can be arranged on the movable element, including the forces that may occur during assembly. The supporting spring element can be designed as a pivoting support for the movable element.With the aid of the spring element, the movable element, which can be provided with a retaining rail and a module, can be pivoted, swiveled, or moved from the operating position into the assembly position and engage there. One end of the spring element is arranged on the support element, and the other end of the spring element is arranged on the movable element. The spring element can be designed as a spiral spring, a buckling spring, or a tab, whereby the tab can consist of a tongue element, and whereby this tongue element can create a resilient effect. Advantageously, assembly can be facilitated by automatically ensuring locking in the assembly position. According to a further embodiment of the invention, the locking element can be arranged on an outer boundary of the movable element.Alternatively or additionally, the locking element can be arranged on a circular section or an at least partially linear extension of the movable element. Optionally, the circular section can be arranged concentrically around a pivot point of the movable element. Alternatively or additionally, the linear extension can be determined by a slotted guide of the support element. The locking element can be arranged perpendicular to the pivoting direction and alternatively or additionally perpendicular to the displacement direction, without changing the outer contour of the movable element in the pivoting direction and alternatively or additionally in the displacement direction. In other words, the locking element can be designed as a thickening of the outer contour of the movable element in the pivoting direction and alternatively or additionally in the displacement direction. The pivot point of the movable element is created by the rotatable arrangement of the movable element on the support element.A spring with two positions can also be arranged in the pivot point. One position is a detent position of the movable element, and the other is an operating position of the movable element. The spring can be designed as a torsion bar spring, a frog spring, or the like, in which no further detent elements are necessary because the spring remains either in the detent position (open position) or in the operating position (closed position). A link is a guide that specifies a relative movement of a movable element to a support element. It is advantageously designed as a guide rail and is further advantageously arranged in the movable element or in the support element. As a rule, at least two detent means or two detent elements can engage in the link, so that the relative movement of the movable element and the support element can be specified in at least two dimensions.For example, if the link is curved at least in sections, the relative movement follows the curve of the link. This advantageously prevents the movable element from expanding in the pivoting direction or in the displacement direction, enabling a more compact design of the device. According to another exemplary embodiment of the invention, the locking means can be designed as a spring. Additionally or alternatively, the locking element can be designed as a spring or as a groove. Optionally, the spring can be designed symmetrically or as a body elongated in the direction of movement. The symmetrical spring can be designed as a dome or cupola. The spring can be designed as a dome- or cupola-like elevation of the locking means or locking element. Alternatively, it can also be designed as a block-like elevation along the direction of rotation or the displacement direction.The block-like elevation can be provided with oblique (inclined) flanks to guide the locking element or locking means. The groove is designed for the positive engagement or locking of the spring. If both the locking means and the locking element are designed as a spring, a locking mechanism can be created by arranging two springs on the movable element or on the support element, which form a positive connection with the spring on the support element or on the movable element. Alternatively, two internal springs arranged in the direction of displacement in the guide of the support element or in the movable element can form a positive connection with two external springs arranged in the direction of displacement on the movable element or on the support element. Finally, the locking mechanism can also be designed with a spring and the stop. A locking device can thus advantageously be formed through simple design measures.According to one embodiment of the invention, the geometric shape of the locking element and locking means can mutually block each other geometrically. Optionally, the dimensions of the locking element and locking means can also be identical. With a mutually blocking geometric shape of the locking element and locking means, the locking element and locking means can be designed as springs, which can be designed, for example, as a dome, a spike, or a cupola. The dome, the spike, or the cupola can be designed such that they create a complete positive connection with their counterparts. This can also be the case with identical dimensions of the locking element and locking means. Alternatively, the locking could also be implemented without a locking means, in which a frictional connection is achieved by one conical element moving into an inverse conical element, and the locking of the movable element is achieved only by friction.The slope of the cone can then be used to adjust the sliding ability or friction, thus determining the force required for fastening or releasing. To reduce the design effort for the device elements, previously constructed locking elements or locking means (e.g., domes, spikes, or cupolas) can advantageously be reused. According to a further embodiment of the invention, the geometric shape of the locking element and locking means can correspond to one another, so that the locking means can be locked into the locking element. This correspondence can be understood as a positive fit. Preferably, the locking means can be designed as a spring, and the locking element as a groove that fits the spring in a positive fit. In this case, a positive locking of the spring in the groove can be achieved. The high holding force during the positive fit advantageously reduces the geometric dimensions of the locking element and locking means.According to another embodiment of the invention, the locking element and, additionally or alternatively, the locking means can be designed to be elastic. Optionally, the material of the locking means can correspond to the material of the support element or the movable element, in particular can be identical to it. Additionally or alternatively, the material of the locking element can correspond to the material of the support element or the movable element, in particular can be identical to it. In this case, the person skilled in the art understands elasticity as the property of a body or material to change its shape under the action of force and to return to its original shape when the acting force is removed (for example, in the case of a spring element). An elastic design of the locking means and locking element brings about a positive but releasable locking connection between the movable element and the support element.Locking means and locking elements can be structural features of the movable element and, alternatively or additionally, of the support element, and can be made of the respective material of the movable element or the support element. In an alternative embodiment, they can also be manufactured separately and arranged on the movable element and, additionally or alternatively, on the support element. Locking means and locking elements can have corresponding shapes, which can be designed, for example, as a tongue and groove. However, they can also have mutually blocking shapes, for example, as two interlocking tongues. The locking means and locking elements are designed to be wear-free and allow a variety of locking and unlocking processes.This advantageously simplifies the design of the locking means and locking element, since no additional elastic components are required to achieve the locking effect. According to one embodiment of the invention, the locking element and, alternatively or additionally, the locking means can be designed to be inelastic. At least the locking element and, alternatively or additionally, the locking means can be changed in position relative to the support element or the movable element. Optionally, the position change can be achieved by displacement, rotation, and, additionally or alternatively, by distancing relative to the support element or the movable element.In the case of an inelastic locking means or locking element, the associated locking element or locking means can be designed elastically so that sufficient elasticity is available for locking or unlocking in a plane of movement (without movement directed radially to the axis of rotation or perpendicular to the direction of displacement). If the locking element and the locking means are designed inelastic, locking can be effected or released by a temporary relative change in the position of the movable element and support element axially to the axis of rotation or perpendicular to the direction of displacement. The temporary relative change in position can occur against a spring force that holds the movable element and the support element in the locked position into a changed position. The changed position can be arranged axially to the axis of rotation in the case of a rotation or perpendicular to the direction of displacement in the case of a displacement.Advantageously, an elastic design of the locking element and, alternatively or additionally, the locking means can be dispensed with, particularly when the movable element and the support element are made of inelastic material. According to a further embodiment of the invention, a further locking means can be arranged in addition to the locking means, so that the movable element can be locked on the support element in one position and another position. Optionally, the further locking means can be arranged corresponding to the locking means on the circular section or other at least partially linear extension of the link of the movable element. The further locking means can correspond to the locking means in its geometric design. The further locking means can also comprise several further locking means, so that a plurality of locking positions between the movable element and the support element are possible.By arranging the additional locking means corresponding to the arrangement of the locking means (for example, on the circular section or on the at least partially linear extension of the link), locking can be achieved with a locking element on each locking means. Advantageously, locking can thus be achieved at a plurality of relative positions of the movable element and the support element. According to one embodiment of the invention, locking of the support element on the movable element can occur between the locking means and the locking element and / or between the locking means and a further locking element. Alternatively, locking of the support element on the movable element can occur by locking the locking means on the locking element and, additionally or alternatively, locking the additional locking means on the additional locking element. The additional locking element can have the shape and dimensions of the locking means designed as a spring.Preferably, it can be arranged on the circular segment or in the direction of displacement on which the locking means is also arranged. The further locking means can comprise a plurality of additional locking means. The locking means are preferably equally spaced, for example, by the same radian measure or the same distance. Advantageously, a simple locking mechanism for multiple locking points can thus be formed. According to another embodiment of the invention, in the movable element, the locking element and the further locking element in the form of a spring can be arranged in a recess in the support element designed as a link, so that the displacement of the movable element follows the geometric design of the link. Optionally, the locking element and the further locking element in the form of a spring can be geometrically identical.Further optionally, at least one locking means in the form of a spring can be arranged in the gate for locking with the locking element or the further locking element. The locking elements can be designed as cylinders, squares, or as triangular columns. At least with a cylindrical or triangular design of the locking elements, the at least one locking means can be designed as a block-like elevation with inclined flanks. Furthermore, the locking means can be arranged on one side of the gate. Alternatively or additionally, the locking means can also be arranged on both sides of the gate. The bilateral arrangement can be made alternately at different positions in the gate or at opposite (identical) positions in the gate.Advantageously, other relative movement forms can be realized in addition to a relative rotation of the movable element and the support element, for example, so that the support rail can be tilted 90° forward or 90° backward. According to one embodiment of the invention, the geometric design of the guide rail can assume an at least partially linear, bent, angled, or curved shape. Optionally, the geometric design of the guide rail can assume a plurality of linear, bent, angled, and curved shapes. The angled shape can include a 90° bend. The curved shape can have a circular arc, which in turn can include a detent position. Detent positions can be formed at all points within the guide rail. Advantageously, a large number of different detent positions can be formed in this way.According to a further embodiment of the invention, a plurality of locking means and a plurality of locking elements can be designed and arranged to form a ratchet toothing. A ratchet toothing is formed by a plurality of locking positions that are arranged at equal distances or equal locking angles from one another. Optionally, the number of locking positions can be limited by at least one stop, which can also be designed as the end of the link. Further optionally, a further movement of the movable element, the support element, or another element can occur perpendicular to the ratchet movement, which is moved, for example, via a thread by rotating the support element or the other element. Advantageously, a plurality of expedient relative arrangements of the movable element and the support element can thus be achieved. A second aspect comprises a holder for mounting attached modules.This comprises at least one support element designed for mounting on a support rail (support rail) according to the first aspect or one of the associated embodiments, and a movable element designed for locking with the support element and for receiving a module arranged on a further support rail according to the first aspect or one of the associated embodiments. The holder has a locking position (mounting position) that provides access to a further module that can be accommodated on the support rail for adjustment, wiring, or the like. Optionally, access to a module that can be arranged on the movable element for adjustment, wiring, or the like can also be provided in the locking position.Optionally, the holder can also comprise a further support element with a further movable element, wherein the movable element together with the further movable element have fastening means to which the further holding rail can be received or fastened at an axial distance. A holding rail or support rail can be designed in accordance with DIN EN 60715, VDE 0611-3, DINEN 60947-7-2, VDE 0660-520. These are suitable for accommodating electrical modules (module and further module) and can be designed, for example, as a top-hat rail. By using a support rail, the optimization of the installation space can be improved and the assembly effort minimized. For the purposes of the invention, (electrical) modules include, in particular, electrical and electronic switching devices as well as electrical boards (e.g.This term refers to interface boards (e.g., in the form of individually populated printed circuit boards) with signal processing and, additionally or alternatively, signal display, but also to simple interface boards, via which only connections between different conductors (in particular with different conductor cross-sections) are established. These provide control, regulation, and information signals that can be used, for example, for process control. Advantageously, a compact installation can thus be provided, for example, for process control. According to an embodiment of the second aspect, the movable element 20 has fastening means to which the further holding rail 220 can be fastened. Additionally or alternatively, the movable element 20 has further fastening means to which the module 210 can be fastened.Optionally, the holder can include a locking verification device, in which, for example, an electrical contact is activated upon correct locking in the locking position or in the operating position. Additionally or alternatively, an error signal can indicate incorrect locking of the movable element to the support element. Alternatively or additionally, the error signal can be implemented visually by a marking and additionally or alternatively acoustically by an acoustic event (audible "click"). This advantageously allows for secure fastening of the additional retaining rail 220 or the module 210, as well as reliable locking during assembly and operation. The invention and the technical environment are explained in more detail below with reference to the figures. It should be noted that the invention is not intended to be limited by the exemplary embodiments shown.In particular, unless explicitly stated otherwise, it is also possible to extract partial aspects of the facts explained in the figures and to combine them with other components and findings from the present description and / or figures.

Fig. 1 shows a simplified view of a device 10 in a first positioning.The device 10 is designed for locking a movable element 20 to a support element 30. The support element 30 has a locking means 50 designed as a spring. The locking means 50 of the support element 30 is locked to the locking element 60, designed as a groove, of the movable element 20. The locking is carried out by rotating the movable element 20 relative to the support element 30. In addition to a locking position 80 formed by the locking (not shown, see Fig. 3), the support element 30 and the movable element 20 have an operating position 90 having a further locking. The movable element 20 has a stop 70 and optionally a further stop 75, which limits the movement of the support element 30 and the movable element 20 relative to one another in the direction of rotation. A locking device 40 comprises the locking means 50, the locking element 60, the stop 70 and optionally the further stop 75.The locking mechanism (locking device 40) is designed to temporarily lock the support element 30 and the movable element 20 relative to one another. Optionally, locking into the locking position 80 (not shown, see Fig. 3) can be assisted by a spring element, which in the operating position 90 exerts a force on the movable element 20 in the direction of the locking position 80. Fig. 2 shows a simplified perspective view of the device in a first position. The reference numerals in Fig. 1 are used with the same meaning here and are therefore not explained in detail. Additionally, the locking means 230 for the holding rail 220 (not shown) and the further holding rail 220 (not shown) are named. These are designed as hooks or grooves that engage in projections of a holding rail 220 designed as a top-hat rail. Fig. 3 also shows2 shows a first receiving leg 33 of the support element 30 for receiving the movable element 20 and a second receiving leg 35 of the support element 30 for receiving the movable element 20, which are arranged parallel and spaced from one another such that the movable element can be guided therein. Fig. 3 shows a simplified representation of the device 10 in a second position. It corresponds to Fig. 1 or 2 except that the movable element 20 is shown here in the locking position 80. The movable element 20 is pivoted out by 90° about the pivot point 120 and also includes the further stop 75. Fig. 4 shows a detailed view of the device 10, wherein the locking element 60, designed as a groove, is arranged on an outer boundary of the movable element 20. In addition, the locking element 60 is arranged on a circular segment of the movable element 20.The circular segment is arranged concentrically around a pivot point 120 of the movable element 20. The locking means 50 is designed as a spring. The spring 140 is designed symmetrically. The symmetrical spring can be designed as a dome or cupola. The geometric shape of the locking element 60 and the locking means 50 can alternatively also be designed to geometrically block each other (not shown). Optionally, the dimensions of the locking element 60 and the locking means 50 can be identical, in particular for the locking element 60 designed as a spring and for the locking means 50 designed as a spring, for example, when designed as a dome or cupola. The geometric shape of the locking element 60 (groove) and the locking means 50 (spring) shown in Fig. 4 correspond to one another, so that the locking means 50 can be positively engaged in the locking element 60. The locking element 60 (groove) and, additionally or alternatively, the locking means 50 (spring) are designed to be elastic.Optionally, the material of the locking element 50 (spring) corresponds to the material of the support element 30. Alternatively or additionally, the material of the locking element 60 (groove) can correspond to the material of the movable element 20. By using the identical material, which can be suitable for use as a plastic injection-molded part, efficient production of the locking element 60 (groove) and additionally or alternatively the locking element 50 (spring) is ensured. The locking element 60 and additionally or alternatively the locking element 50 can also be designed to be inelastic. In this case, a position change relative to the support element 30 or the movable element 20 is possible at least for the locking element 60 and additionally or alternatively for the locking element 50 (not shown). Optionally, the position change can be achieved by displacement, rotation, and additionally or alternatively by distancing relative to the support element 30 or the movable element 20 (not shown). Fig.Fig. 5 shows a simplified representation of the device 10 of a further embodiment in a first position. In contrast to Fig. 4, instead of the concentric pivot point for the movement of the movable element 20, a slotted link 130 of the support element 30 has been substituted, wherein the slotted link 130 has straight sections (linear extension in sections) and curved sections. In the slotted link 130, the locking means 50 is designed as elongated springs 140 (body elongated in the direction of movement). The movable element 20 comprises two locking elements 60 designed as columns, which are arranged in the slotted link 130 of the support element 30 in the locking position 80. In addition to the locking means 50, a further locking means 150, also as elongated springs 140, is arranged in the slotted link 130, so that the movable element 20 can be locked to the support element 30 in one position and another position.The stop 70 and the further stop 75 limit the mobility of the movable element 20. Optionally, the further locking means 150 can be arranged, corresponding to the locking means 50, on the at least partially linear extension of the link 130 of the movable element 20. Fig. 6 shows a detailed view of the device 10 in a third embodiment, in which the support element 30 is shown in a detail. This detail shows the arrangement of the locking means 50 and two further locking means 150 in the form of a spring 140 along the circular segment 110 around the pivot point 120. The locking means 50 is arranged on a first receiving leg 33 of the support element 30 for receiving the movable element. The two further locking means 150 are arranged on the second receiving leg 35 of the support element 30 for receiving the movable element 20.The second receiving leg 35 is arranged parallel to and spaced from the first receiving leg 33, so that the arrangement of the receiving legs 33 / 35 is designed to receive the movable element 30. The first receiving leg 33 and the second receiving leg 35 each have a recess formed as a circular segment, with the remaining circular segments of the first receiving leg 33 and the second receiving leg 35 being arranged opposite one another. In a different embodiment, the geometric shape of a locking element 60 (not shown) designed as a spring and a locking means 50, 150 designed as a spring can be designed to geometrically block each other. In this case, two locking elements 60 would be arranged on either side of the locking means 50, 150 to form the locking of a locking or an operating position (not shown). Optionally, the dimensions of the locking element 60 and the locking means 50 can also be identical.Accordingly, the support element 30 can be locked to the movable element 20 (not shown) between the locking means 50 and the locking element 60 (not shown) and a further locking element (not shown). If, contrary to the above section, the locking element 60 is designed as a groove 145, one locking element 60 is sufficient for locking with the locking means 50 designed as a spring 140. Alternatively, the support element 30 can be locked to the movable element 20 by locking the locking means 50 in the form of a spring 140 to the locking element 60 in the form of a groove 145 (not shown) and by locking the further locking means 150 in the form of a spring 140 to the further locking element 160 in the form of a groove 145. Accordingly, two locking mechanisms can be formed simultaneously. Thus, a plurality of locking means 50, 150 and a plurality of locking elements 60, 160 can be designed and arranged for simultaneous engagement with one another to form a ratchet toothing.Fig.Figure 7 shows a perspective view of the structural elements configured for the rotation of the movable element 20 in the support element 30. The structural elements comprise two half pins 23 / 26, which are arranged axially in opposite directions on opposite sides of the movable element 20. The support element 30, in a perspective view, has a first recess 39 configured as a circular segment in its first receiving leg 33, and recesses 37 configured as circular segments in its second receiving leg 35. The remaining circular segments of the first receiving leg 33 and the second receiving leg 35 are arranged opposite one another in opposite directions, corresponding to the arrangement of the half pins 23 / 26. Arranging the half pins 33 / 35 in the corresponding recesses 37 / 39 results in a pivotability of the movable element 20 in the support element 30, with a rotation angle limited to 90°. This is clear from Fig. 8a and 8.Fig.8a and 8b show a simplified representation of the movable element 30 arranged in the support element 20 from opposite perspectives. Fig. 8a shows the pin 26 from a right-hand perspective, and Fig. 8b shows the pin 23 from a left-hand perspective. The locking position 80 is shown, which can also be referred to as the service position. Two stops 303, 306, 308, and 309 are shown, two each for the operating position 90 and two for the locking position 80. Two stops 306 / 309 or 307 / 308 are always connected in parallel.

In the movable element 20, the locking element 60 and the further locking element 160 in the form of a cylindrical spring 140 are arranged in a recess of the support element 30 designed as a link 130 in the operating position 90, so that the displacement of the movable element 20 follows the geometric configuration of the link 130. The locking element 60 and the further locking element 160 are geometrically identical. The stop 70 and the further stop 75 limit the mobility of the movable element 20. The geometric design of the link 130 is linear (linear extension).Optionally, the link 130 can also assume an at least partially linear, bent, angled, or curved shape. Further optionally, the geometric configuration of the link 130 can assume a plurality of shapes: a linear, a bent, an angled, and a curved shape. The angled shape can include a 90° bend. The curved shape can have a circular arc, which in turn can include a locking position. Fig. 10 shows a simplified representation of a holder 200 in a first embodiment. The holder 200 is designed for mounting attached modules 210. It comprises a support element 30 designed for mounting on a holding rail 220 according to one of the above embodiments and figures and for locking with the support element 30 and for receiving a movable element 20 designed according to one of the above embodiments and figures, arranged on a further holding rail 220.The holder 200 is shown in a locking position 80, providing access to an additional module 210 arranged on the holding rail 220 for adjustment and, alternatively or additionally, wiring. The stop 70 and the additional stop 75 limit the mobility of the movable element 20. Optionally, in the locking position 80, access to the module 210 attached to the holding rail 220 can also be provided for adjustment and, alternatively or additionally, wiring. The movable element 20 is designed for fastening the additional holding rail 220 and, optionally, for fastening the module 210.Optionally, the holder 200 can also comprise a further support element 30 with a further movable element 20 (not shown) axially spaced from the support element. The movable element 20 and the further movable element 20 each have a fastening means (not shown) to which the further holding rail 220 can be received or fastened at an axial distance. The holder can comprise a latching check (not shown), in which, for example, an electrical contact is actuated. This can influence a signal indicating incorrect latching of the movable element to the support element. Fig. 11 shows a simplified perspective view of the holder 200 in a second embodiment. Here, the holder 200 comprises the further holding rail 220 arranged on the movable element 20, which is designed as a top-hat rail. The top-hat rail, in turn, is designed to receive the module 210, as shown.The movable element 20 is shown in the holder 200 in a locking position 80, allowing access to an additional module 210 arranged on the support rail 220 for adjustment and, alternatively or additionally, wiring. The additional stop 75 limits the mobility of the movable element 20. In other words, the invention can also be described as follows: The invention relates to a compact arrangement of electrical modules 210 in two levels on a lower support rail 220 and an upper support rail 220, technically referred to as a second-level board installation (SLBI), for limiting the length of the lower support rail 220, for example, when using the lower support rail 220 in a control cabinet.More specifically, the invention lies in a specific locking mechanism (locking, for example in the form of a step lock) that prevents the movable element 20 (lever arm) from springing back or pivoting back in a pivoted-out state, creating a pivoted-out locking position 80 in which the movable element 20 is fixed. In embodiments, multiple locking positions 80, including a 45° position relative to the retaining rail 220, can be provided for the movable element 20, so that locking can occur at various pivoting angles. The locking mechanism allows for trouble-free installation and maintenance work on the lower module installed on the retaining rail 220. The locking mechanism (locking) is designed such that it prevents springing back or pivoting in the open state, for example, by (simply) locking the movable element 20 in the locking position 80.In embodiments, a multi-stage locking mechanism, particularly in the form of a ratchet function, can be included. Embodiments include pivoting of the movable element 20 (lever arm) about a pivot point 120. Further embodiments include, instead of the pivot point 120, a link 130 (sliding carriage) in the support element 30. In some embodiments, this can allow displacement of the movable element 20 parallel to the support rail 220 (carrying rail). In further embodiments, the shape of the link 130 can have a 90° angle to the lower support rail 220. In other embodiments, the link 130 can move away from the lower support rail 220, at least in sections, in an upwardly directed circular arc. All embodiments with the link 130 have locking points 80 (locking devices) for the movable element 20. Further details can also be found in the figures.Although the invention has been described with reference to exemplary embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted. Furthermore, many modifications may be made to adapt a particular installation situation or circuit arrangement to the teachings of the invention. Consequently, the invention is not limited to the disclosed embodiments, but encompasses all embodiments falling within the scope of the appended claims.
