Description

[0001] Locking assembly for holding a magazine for storing attachments

[0002] The invention relates to a locking assembly for receiving a magazine for storing attachments and a system comprising a locking assembly.

[0003] Means for storing add-on components, in particular for storing electrical add-on components, in control cabinet, machine, and plant engineering are known from the prior art. When equipping a mounting rail, which can also be referred to as a top-hat rail or profile rail and is designed for attaching electrical add-on components in distribution boxes, the required electrical add-on components are often removed from packaging, for example a box, a bag, or a bulk container, and arranged on the mounting rail. The electrical add-on components, for example terminal blocks, are manually pushed sideways onto the mounting rail by a user, a worker, or an installer.

[0004] The add-on parts are in a disordered state at the time of removal, requiring the user to perform sorting in addition to the assembly work. The resulting time expenditure leads to significant delays in the assembly process. Therefore, magazines are often used in the prior art to store add-on parts, as described, for example, in DE 10 2010 047 369 A1 and WO 2010 / 057768 A1. DE 10 2020 118 829 A1 describes a packaging box in which add-on parts are stored in the correct position and can be removed individually from the packaging box.

[0005] For example, a magazine for storing attachments can have a holding rail with a web running in a direction of travel of the holding rail and with two collar elements arranged opposite one another in the direction of travel, which are arranged on the sides of the web, for connecting to a holding geometry of the attachments, and a stop element that can be arranged at an end region of the holding rail. At the user's workstation, the rail can be held by means of a holder with a slight incline to allow the attachments to slide along the holding rail towards the stop element. Furthermore, a sliding element designed as a weight can be arranged on the holding rail, which further assists the sliding of the attachments.

[0006] However, the magazines known from the state of the art for storing attachments have the disadvantage that loading and fastening such magazines is often complex and requires the use of additional tools.

[0007] The object of the present invention is to provide a locking assembly for receiving a magazine for storing attachments, which can be securely anodized to a surface, such as a shelf, without the use of tools, for loading and storing the magazine.

[0008] This object is achieved by an article having the features of claim 1.

[0009] Accordingly, the locking assembly for receiving a magazine for storing attachments comprises a guide rail having a guide profile adapted to engage with a corresponding guide profile of the magazine in order to hold the magazine displaceably at least in certain regions in a direction of travel of the guide rail, wherein the guide rail has at least one through-opening, in particular a through-opening designed as an elongated hole or as a cylindrical opening. Furthermore, the locking assembly has at least one latching element that can be arranged on a base and at least one holding element that is adapted to hold the guide rail movable on the base, at least in certain sections, in a direction orthogonal to the direction of travel of the guide rail, in order to enable a movement, in particular a pivoting movement, of the guide rail beyond the latching element in the direction of travel.In a locking position, the locking element is adapted to extend through the through opening in the guide rail and to engage at least partially in an opening of the magazine in order to lock the position of the magazine on the guide rail.

[0010] The accommodateable magazine can have a holding rail on which the attachments can be arranged or are arranged. On a side of the holding rail facing away from the accommodated attachments or on at least one of the side surfaces of the holding rail, a corresponding guide profile to the guide profile of the guide rail is formed. For example, the corresponding guide profile can be designed as a guide groove that extends in a direction of travel of the holding rail and that can engage around a web-shaped elevation of the guide rail, for example. The magazine is thereby held displaceably on the guide rail, at least in some regions, in a direction of travel of the guide rail.

[0011] Furthermore, the guide rail has at least one through-opening which can extend cylindrically or rectangularly through the material of the guide rail.

[0012] The holding element is adapted to hold the guide rail on the substrate so that it can move, at least in sections, in a direction orthogonal to the direction of travel of the guide rail, in order to enable movement, in particular pivoting, of the guide rail beyond the locking element in the direction of travel. The magazine, which is slidably received in the guide rail, can be moved, in particular pivoted, together with the guide rail in a direction orthogonal to the substrate.

[0013] In the locking position, the locking element extends with its second end portion through the through-opening in the guide rail and further into an opening in the magazine arranged on the guide rail, for locking the position of the magazine relative to the guide profile. The opening in the magazine can be an opening in one side of the magazine's retaining rail, opposite the side with the attachments arranged thereon, and into which the locking element, which already extends through the through-opening in the guide rail, can be inserted at least partially.

[0014] The locking assembly allows the user to handle the magazine with one hand, i.e. to load, secure and remove it from the magazine assembly with one hand.

[0015] In one embodiment, in a further locking position, the locking element is adapted to extend through the through opening in the guide rail and to engage at least partially in a further opening of the magazine.

[0016] The additional opening is spaced apart from the opening in the magazine material in the direction of extension. The two openings can each be centered on the side of the magazine's holding rail opposite the side with the attached components. The distance between the openings determines the distance between the two locking positions at which the magazine can be moved along the guide rail.

[0017] In one embodiment, the locking element is adapted to hold a first end region of the magazine in the locking position over an end region of the substrate, in particular flush with an edge of the substrate, and to hold the first end region of the magazine in the further locking position protruding over the end region of the substrate.

[0018] The two defined locking positions can be a working position for removing the attachments during the assembly process and a loading or half position for filling the magazine with attachments.

[0019] By locking the magazine in both positions, ergonomic removal and loading with one hand is possible.

[0020] In one embodiment, the guide rail comprises a ferromagnetic material and the locking group comprises at least one magnetic element, wherein the magnetic element is designed to be arranged on the substrate and is adapted to hold the guide rail in the locking position and the further locking position by means of magnetic force.

[0021] In the two locking positions, the magnetic element acts with a defined magnetic force on the guide rail in the direction of the ground in order to prevent unintentional lifting and thus unlocking or unlatching.

[0022] In one embodiment, the locking element comprises the magnetic element.

[0023] For example, the locking element can be magnetic to avoid the use of separate elements.

[0024] In one example, the locking assembly comprises at least one spring element, which is configured with opposite end regions to be arranged on the base and on the guide rail, and is adapted to hold the guide rail in the locking position and the further locking position by means of spring force. As an alternative to the magnetic element, a spring element can also be used to hold the guide rail in the locking positions on the base.

[0025] In one embodiment, the locking element is designed in a pin-like manner and can be arranged on the substrate orthogonally to the direction of travel of the guide rail.

[0026] The locking element, which can be arranged on the base, for example on a sheet metal shelf, can also be referred to as a locking bolt and can have a substantially cylindrical shape in the direction of extension. In the assembled position, the locking element extends orthogonally from the base. For example, the locking element can be arranged at a first end region in an opening in the base and held in the opening. A second end region of the locking element, opposite the first end region, can extend in the direction of the guide rail. A circumferential bevel can be attached to the second end region of the locking element to simplify insertion of the locking element into the respective openings or through the respective openings.

[0027] In one embodiment, the locking assembly comprises at least one funnel-shaped receiving element arranged at an end region of the guide rail for receiving the magazine in the guide rail. In a further embodiment, the locking assembly comprises at least one further funnel-shaped receiving element arranged at a further end region of the guide rail, opposite the end region, for receiving the magazine in the guide rail.

[0028] The two funnel-shaped receiving elements can be designed identically and, when mounted on the guide rail, are positioned at an angle of 180° to each other. The funnel-shaped design of the receiving elements allows for easy insertion of the magazine onto the guide rail.

[0029] The at least one retaining element can be connected to one of the funnel-shaped receiving elements in order to hold the guide rail on the substrate so that it can move, at least in sections, in a direction orthogonal to the direction of extension of the guide rail. In one embodiment, the at least one retaining element is longitudinally shaped and extends, at least in sections, through a through-opening in the material of the substrate.

[0030] Several equally or differently spaced through-holes can be provided in the material of the base, for example, the shelf base, for arranging several similar locking assemblies next to each other. For example, the base can have two identical, consecutive through-holes for each locking assembly, into which a holding element connected to the funnel-shaped receiving element, each with an end region, can be inserted. Alternatively, the at least one holding element, in particular two holding elements, can also be connected directly to the guide rail.

[0031] In one embodiment, the locking assembly has at least one locking element, in particular a locking clamp or a locking pin, wherein the locking element is designed to be connectable at least in some areas to an end region of the holding element opposite the guide rail, for determining a maximum pivoting height of the guide rail.

[0032] In one embodiment, the holding element is designed as at least one spring clamping element, in particular as at least one spring clamping element with at least two clamping positions for releasably clamping the holding element in the through-opening, wherein the clamping positions are arranged orthogonally to the direction of travel of the guide rail.

[0033] For example, the spring clamp element can be implemented as a spring clip with one or more clamping legs. The clamping positions can be determined by the contour of the clamping legs. For example, notches or recesses can be arranged on the clamping legs, or the clamping legs can be designed with notches and recesses to determine the clamping positions. In the respective clamping positions, the notches and recesses can be arranged in the through-opening to clamp the holding element with the receiving element arranged thereon in the respective clamping position in the through-opening.In a first clamping position, the clamping element and thus the receiving element can be held directly, or substantially directly, on the substrate and in a second clamping position can be held at a distance from the substrate in order to enable movement of the guide rail over the locking element in the direction of travel.

[0034] By designing the holding element as a spring clamp element, the use of separate locking elements is eliminated. Furthermore, the spring clamp element can also take over the function of the previously described magnetic element and prevent accidental lifting and thus unlocking or unlatching in the clamped positions. In certain embodiments, holding elements designed as spring clamp elements can also be used together with magnetic elements to ensure a particularly secure hold in the latched positions.

[0035] In one embodiment, the holding element has a hold-down element which is adapted to hold the holding element to the substrate.

[0036] The hold-down element can be arranged on the retaining element of the locking assembly, which, in the assembled position, forms a pivot point when the locking assembly is transferred between the locking positions. For example, the hold-down element can be designed as a locking lug or a hook-shaped element, and in the locking positions, i.e., the locking position and the further locking position, or in the first clamping position when the clamping element is held directly, or essentially directly, on the substrate, it can at least partially encompass the through-opening in order to absorb any torque that may occur, for example, when removing attachments.

[0037] In one embodiment, at least one locking element, in particular a spring-loaded locking element, is arranged on the retaining element and, in a closed position, is adapted to hold the retaining element in the through-opening in the material of the substrate, thus defining a maximum pivoting height of the guide rail. The locking element is further adapted, in an open position, to allow removal of the retaining element from the through-opening in the material of the substrate.

[0038] The locking element can also be referred to herein as a "spring latch" and, in the closed position, extends at least partially from a surface of the retaining element, thereby holding the retaining element in the through-opening in the material of the substrate. Furthermore, the locking element can be displaced toward the retaining element or into the retaining element, for example, against the spring force of a spring element, to transfer it to the open position.

[0039] In one embodiment, the locking assembly comprises at least one additional retaining element, wherein the retaining element and the additional retaining element are arranged at opposite end regions of the guide rail. The retaining elements can be arranged directly at the opposite end regions of the guide rail or can each be arranged on the guide rail via a funnel-shaped receiving element.

[0040] When transferring the locking assembly between the locking positions, the additional holding element can form a pivot point. A further locking element can be arranged on the additional holding element, in the embodiment with a locking element, such that it rests directly or substantially directly on a side of the substrate opposite the guide rail. For this purpose, the locking element can be arranged on one of at least two arrangement planes on the holding element, which is located close to the substrate in the assembled position. Alternatively, the additional holding element, in the embodiment as a spring clamp element, can be held in the first clamping position, i.e. directly or substantially directly on the substrate.

[0041] Furthermore, the invention relates to a system comprising: at least one locking assembly as described herein; at least one magazine for storing attachments; and a base.

[0042] In one embodiment, the magazine for storing attachments comprises a retaining rail with a web extending in a direction of travel of the retaining rail and having two collar elements opposite one another in the direction of travel on the sides of the web for connecting to a retaining geometry of the attachments, and a stop element that can be arranged or is arranged at an end region of the retaining rail. In one embodiment, the magazine further comprises a guide profile on the retaining rail, which is configured to correspond to the guide profile of the guide rail.

[0043] In one embodiment, the base is designed as a shelf, in particular as a shelf base plate, and has at least one through-opening for the at least one holding element, in particular the base has a plurality of through-openings for a plurality of holding elements.

[0044] The locking device can be quickly and easily mounted and removed from the surface without tools. For disassembly, in the design with locking elements, only the two locking elements need to be released. After releasing the two locking elements, the remaining elements of the locking assembly can be easily removed. In the design of the holding elements as spring clamp elements, only the spring clamp elements need to be released to remove the locking assembly.

[0058] Embodiment.

[0059] Figure 1 shows a schematic view of a locking assembly 1 according to an embodiment with a magazine 100 and a base 200 in a non-assembled position.

[0060] The magazine 100, which can be accommodated in the locking assembly 1, has a holding rail 110 on which the attachments can be arranged. A guide profile 114A, 114B corresponding to the guide profile 11A, 11B of the guide rail 3 is formed on the side surfaces of the holding rail 110. As shown, the corresponding guide profile 114A, 114B comprises two groove-shaped undercuts that extend along the side surfaces of the holding rail 110 in a direction of travel, V, of the holding rail 110 and that can engage a guide profile 11A, 11B of the guide rail 3. In the embodiment shown, the guide profile 11A, 11B of the guide rail 3 is formed from two guide grooves. The magazine 100 shown is thus displaceable at least partially along the direction of travel V on the guide rail 3. As shown, a stop element 104 is arranged at one end region of the holding rail 110.Also shown in Figure 1 is a sliding element 102 arranged on the holding rail 110, which can push attachments (not shown) located on the holding rail 110 toward the stop element 104. In the embodiment shown, the guide rail 3 of the locking assembly 1 has a funnel-shaped receiving element 5A, 5B at each of the opposite end regions of the guide rail 3. The two funnel-shaped receiving elements 5A, 5B are of identical design and, when mounted on the guide rail 3, are at an angle of 180° to one another. The funnel-shaped receptacle of the receiving elements 5A, 5B enables easy insertion of the magazine 100 onto the guide rail 3.On the undersides of the receiving elements 5A, 5B, which are opposite the magazine 100, holding elements 7A, 7B are arranged, which extend at least partially through a respective through-opening 202A, 202B in the material of the base 200 shown as a shelf. Furthermore, Figure 1 shows the locking element 12 and the magnetic element 14, both of which can be arranged on the base 200.

[0061] Figure 2 shows a schematic rear view of the locking assembly 1 in an assembled position.

[0062] The locking assembly 1 shown is the locking assembly 1 previously shown in Figure 1 with a magazine 100 arranged therein in an assembled position. For this purpose, the holding elements 7A, 7B extend through the respective through-openings 202A, 202B in the material of the base 200 shown as a shelf. In the assembled position shown in Figure 2, the locking elements 9A, 9B shown as connecting clips are connected to the end regions of the holding elements 7A, 7B opposite the guide rail 3 in order to limit an orthogonal movement of the holding elements 7A, 7B relative to the direction of travel V. In the embodiment shown, the locking elements 9A, 9B are substantially flat and are arranged between opposite guide grooves on the holding elements 7A, 7B to lock the holding elements 7A, 7B.

[0063] Figure 3 shows a schematic detailed view of an end region of the locking assembly 1 with the magazine 100 arranged thereon in the mounted position. The locking assembly 1 is a locking assembly 1 according to the embodiment already shown in Figures 1 and 2.

[0064] The magazine 100 shown has been pushed onto the guide rail 3 via the funnel-shaped receiving element 5A shown, and is held displaceably in the direction V on the guide rail 3 by means of interlocking guide profiles 11A, 11B, 114A, 114B of the guide rail 3 and the magazine 100. The holding element 7A in the embodiment shown has two opposing guide grooves 71 AA, 71 AB, 71 BA, 71 BB in two planes, into which a locking element (not shown) can be inserted.

[0065] Figures 4A and 4B each show a schematic side view and a sectional view through a first end region of the locking assembly 1, which is arranged on a base 200, and with a magazine 100 arranged on the locking assembly 1.

[0066] Figures 4A and 4B show the locking assembly 1 in the locking position. In the locking position, the locking element 12 extends with its second end portion through the through-opening 31 in the guide rail 3 and further into an opening 103A of the magazine 100 arranged on the guide rail 3, for locking the position of the magazine 100 on the guide rail 3.

[0067] In the sectional view in Figure 4B, it can be seen that the holding element 7A extends through the through-opening 202A in the substrate 200. Furthermore, in the assembled position shown in Figure 4B, the locking element 9A, shown as a connecting clamp, is connected to the end region of the holding element 7A opposite the guide rail 3 in order to limit an orthogonal movement of the holding element 7A, 7B relative to the direction of travel V.

[0068] In order to enable a movement, in particular a pivoting movement, of the guide rail 3 beyond the locking element 12 in the direction of extension, the locking element 9A is arranged between the lower pair of the opposite guide grooves 71 BA, 71 BB, so that the distance between the holding element 7A and the base 200 specifies the maximum path of the pivoting movement.

[0069] To transfer from the illustrated locking position to a further locking position, the magazine 100 is lifted by the user together with the guide rail 3, for example, pivoted, until the illustrated locking element 9A rests on the base 200 and the locking element 12 no longer extends into the opening 103A of the magazine. In the raised position, the magazine 100 is now moved along the direction V over the edge of the base 200 and lowered to the further locking position, where the locking element 12 extends through the illustrated further opening 103B of the magazine 100.

[0070] Figures 5A and 5B show a schematic side view and a sectional view through a second end region of the locking assembly 1, which is arranged on the base 200. The second end region shown in Figures 5A and 5B is opposite the first end region shown in Figures 4A and 4B.

[0071] As already shown in Figures 4A and 4B, the magazine 100 is pushed onto the guide rail 3 and is held on the guide rail 3 so as to be movable in the direction of travel.

[0072] The illustrated receiving element 5B and the illustrated holding element 7B are designed similarly to the receiving element 5A and holding element 7A shown in Figures 4A and 4B. At the end region shown, the locking element 9B is arranged between the upper pair 71AA, 71AB of the opposing guide grooves, so that the small distance between the holding element 7B and the base 200 only allows a limited orthogonal movement of the holding element 7B relative to the direction of travel. Such an arrangement can absorb the torque exerted on the guide rail 3 by the weight of the attachments in the magazine 100. As shown, with the arrangement of the locking element 9B between the upper pair 71AA, 71AB of the guide grooves in the holding element 7B, a form-fit connection between the magazine and the base can essentially be achieved in the second end region shown.When transferring between the locking positions, the end area shown forms the pivot point.

[0073] Figures 6A and 6B show schematic views of the locking assembly 1 in the mounted position with a magazine 100 arranged on a base 200 in the locking position and in the further locking position.

[0074] In the locking position shown in Figure 6A, the first end portion of the magazine 100 is held in an end portion of the base 200, flush with the edge of the base 200. The position shown in Figure 6A can also be referred to as the working position. In the further locking position shown in Figure 6B, the first end portion of the magazine 100 is held protruding beyond the end portion of the base 200. The position shown in Figure 6B can also be referred to as the loading or half-loading position for filling the magazine 100 with attachments.

[0075] As further shown in Figures 6A, 6B, the base 200 formed as a shelf has a plurality of through openings 202A - 202N for arranging a plurality of adjacent locking assemblies 1, each of which can hold a magazine 100 movable in the direction of travel.

[0076] Figures 7A-7D show schematic views of a receiving element 5A' according to another embodiment. On the underside of the receiving element 5A', which is opposite the magazine (not shown), a holding element 7A' is arranged, which is adapted to extend at least partially through a through-opening in the material of the base shown as a shelf, as shown in the following Figures 8A, 8B, and 9.

[0077] In contrast to the holding elements previously shown in the figures according to a first embodiment, which can be arranged on the substrate by means of locking elements, Figures 7A-7D show an embodiment of a holding element 7A' comprising two spring clamping elements 71AA' and 71AB'. The two spring clamping elements 71AA' and 71AB' are essentially U-shaped and made of a spring-elastic material. In the embodiment shown, a first end region of each spring clamping element 71AA' and 71AB' is arranged on an underside of the receiving element 5A' and extends with a first region initially away from the receiving element 5A'. In the course of the extension, the strip-shaped spring clamping elements 71AA' and 71AB' are bent at an angle of up to 180°, so that the spring clamping elements 71AA' and 71AB' extend again in the direction of the receiving element 5A' in a second region.The second end region is thereby essentially in a plane with the first end region and can be moved elastically in the direction of the first end region.

[0078] The two spring clamping elements 71AA' and 71AB' shown enable releasable clamping of the receiving element 5A' in a first clamping position 711AA', 711AB' and in a second clamping position 713AA', 713AB' in the through-opening in the substrate. The clamping positions 711AA', 711AB', 713AA', 713AB' are arranged one above the other and orthogonal to the direction of travel, V, of the guide rail. In the embodiment shown in Figures 7A-7D, the clamping positions 711AA', 711AB', 713AA', 713AB' are realized by a corresponding contour of the clamping legs. As shown, notches or recesses are arranged on the clamping legs to create the clamping positions 711AA', 711AB', 713AA', 713AB'. As shown in the following figures, the notches or recesses are arranged in the through-opening and clamp the receiving element 5A' in the respective clamping position in the through-opening.In the first clamping position 711AA', 711AB', the clamping element can be held directly, or substantially directly, on the substrate and in the second clamping position 713AA', 713AB', it can be held at a distance from the substrate to enable movement of the guide rail over the locking element in the direction of travel.

[0079] Furthermore, in the embodiment shown, the holding element 7A' has a hold-down element 73A' which is adapted to hold the holding element to the substrate.

[0080] In the embodiment shown, the hold-down element 73A' is designed as a locking lug or as a hook-shaped element and can at least partially encompass the through-opening in order to absorb a possible torque that may occur, for example when removing attachments.

[0081] Also, in the embodiment shown, grip elements 715AA', 715AB' are arranged as engagement points at the free ends of the spring clamp elements 71AA', 71AB' in order to simplify assembly / disassembly for the user.

[0082] Figures 8A and 8B show schematic views of the locking assembly 1 with holding elements 7A', 7B' according to the further embodiment in the mounted position with a magazine 100 and arranged on a base 200 in the latching position. Figure 8A shows a front view of the locking assembly 1, and Figure 8B shows a view of an underside of the base 200 with the locking assembly 1 arranged thereon. Figures 8A and 8B show the locking assembly 1 in the latching position, or in the first clamping position 711AA', 711AB'. The sectional view in Figure 8A shows that the holding element 7A' extends through the through-opening 202A in the base 200 and is held in the latching position, or in the first clamping position 711AA', 711AB'.Figure 9 shows a schematic sectional view through a first end region and a second end region of the locking assembly 1 with holding elements according to the embodiment previously shown in Figures 7A - 7D, 8A and 8B.

[0083] The illustrated receiving element 5B' and the illustrated holding element 7B' are designed similarly to the illustrated receiving element 5A' and the illustrated holding element 7A'. At the illustrated end region, the hold-down element 73B' of the holding element 7B' holds the receiving element 5B' and thus the holding rail 110 to the base 200, so that the small distance between the holding element 7B' and the base 200 only allows limited orthogonal movement of the holding element 5B' relative to the direction of travel. Such an arrangement can absorb the torque exerted on the guide rail 3 by the weight of the attachments in the magazine 100. When transferring between the locking positions, the holding element 7B' forms the pivot point.The hold-down element 73A' on the holding element 7A' has no function in the embodiment shown in Figure 9, or rather, the holding element 7A' does not hold to the base 200 and is arranged there only due to the use of identical parts.

[0084] Figures 10A-10E show schematic views of a retaining element 7" according to yet another embodiment. In the illustrated embodiment, a spring-loaded locking element 71" is arranged on the retaining element 7".

[0085] In Figure 10A, the locking element 71" is shown in a closed position. In the closed position, the holding element 7" is held in the through-opening in the material of the substrate 200, for determining a maximum pivoting height of the guide rail. As shown, in the closed position, the locking element 71" extends at least partially from a surface of the holding element 7".

[0086] Figures 10B and 10C show views of the holding element 7" in the closed position without the base 200. The locking element 71" can be moved from the closed position shown into the open position shown in Figures 10D and 10E by pulling the actuating element 711" against a spring force of the spring element 713". The spring element 713" shown is designed as a compression spring in the embodiment shown. List of Reference Symbols
