Description

[0001] The invention relates to an anti-displacement device for a mounting device on a support rail, comprising an elongated base body that can be plugged onto the support rail, wherein a plurality of webs are arranged on the base body and extend perpendicularly from the base body. The webs are designed such that, when the anti-displacement device is plugged onto a support rail, they are positioned below a collar of the support rail and protrude at least partially beyond a width of the support rail. The invention is further directed to a support rail comprising at least one anti-displacement device according to the invention and to a method for attaching a mounting device to a support rail by means of an anti-displacement device according to the invention.

[0002] Surface-mounted devices are typically mounted on a support rail with a clamping mechanism. However, the surface-mounted devices are still easily movable. Therefore, anti-displacement devices are available to prevent displacement, especially lateral displacement. Conventional anti-displacement devices require a tool to retract a clamping or locking mechanism to clamp the surface-mounted devices, and especially to release them. A possibly additional securing mechanism with screws can also be provided.

[0003] For example, DE 37 32 434 A1 describes a mounting device with a clamping device that allows the mounting device to be removed from the mounting rail independently of other mounting devices. The clamping device comprises a locking jaw and a clamping jaw.

[0004] Since hooking the mounting device via a locking jaw only works with a certain amount of play between the locking jaw and the support rail, the clamping force between the mounting device and the support rail is insufficient to securely position the mounting device. EP 22 00 134 B1 therefore proposes a clamping device with a guide rail to provide increased clamping force.

[0005] DE 295 06 579 U1 describes an arrangement for securing an electrical device with a locking slide and, opposite this, a spring-loaded hook molded onto a base. On both sides of the hook are rod-shaped pressure elements for wedging against the edge of a mounting rail when the device is snapped onto it. Similar arrangements are described in DE 74 26 836 U, DE 44 22 021 A1, EP 1 052 749 A1, EP 0 337 226 A1, and DE 35 44 363 C1.

[0006] The disadvantage of the known anti-slip devices is that they form a single unit with the attachments and are therefore not flexible for use with different attachments. Furthermore, they require a tool to release and / or attach the attachments, and the locking and / or clamping devices are technically complex.

[0007] It is therefore the object of the invention to provide a displacement protection device which prevents a displacement, in particular an automatic displacement, of a mounting device on the support rail, which can be used flexibly and independently of a mounting device and which has a low technical complexity.

[0008] This object is achieved by an anti-displacement device having the features of claim 1. The subordinate claim 18 relates to a support rail comprising an anti-displacement device according to the invention, and the subordinate claim 20 relates to a method for attaching a mounting device to a support rail using an anti-displacement device according to the invention. Advantageous embodiments of the invention are the subject of the dependent claims.

[0009] Accordingly, an anti-displacement device for a device mounted on a support rail comprises an elongated base body that can be plugged onto the support rail. A plurality of webs are arranged on the base body, extending perpendicularly from the base body and configured such that, when the anti-displacement device is plugged onto a support rail, they are positioned below a collar of the support rail and, at least in some areas, protrude beyond a width of the support rail.

[0010] Because the webs extend beyond the width of the mounting rail, at least in some areas, they enable the clamping of a device mounted on the mounting rail. In particular, the webs can be flexible, allowing the clamping to be adjusted by changing the shape of the webs, the number of webs, and / or the material of the webs.

[0011] A mounting rail is defined here as a universal support made of a sheet metal or plastic profile. Such a mounting rail is also referred to as a DIN rail and can, for example, be designed as a top-hat rail with a top-hat profile. Mounting rails are used, for example, in electrical engineering for mounting electrical equipment in distribution boxes, control cabinets, junction boxes, etc. The sheet metal profile can be made of steel, copper, or aluminum. Corresponding mounting rails are standardized, for example, in DIN EN 60715.

[0012] A surface-mounted device is understood here to mean components, particularly electronic components, for mounting, for example, by sliding or plugging onto mounting rails. A surface-mounted device can be or include, for example, a relay, a latching switch, a timer, a circuit breaker, or a terminal block.

[0013] The base body is understood here to be the base of the anti-displacement device. When plugged in, this can extend along a section of a side surface of the support rail. In particular, the base body can be designed so that it rests against or rests on a lateral surface of the support rail.

[0014] Plugging in can, but does not necessarily, involve plugging in the sense of a force-locking connection. Plugging in also encompasses contact or resting against the mounting rail. In particular, plugging in here refers to a fixed, i.e., displacement-proof positioning of the anti-displacement device on the mounting rail, especially on an outer side surface of the mounting rail. The anti-displacement device is preferably detachably pluggable, so that it can also be retrofitted to a mounting rail.

[0015] A collar is a folded upper section of the support rail onto which the mounting device is attached.

[0016] Here, "partial projection" means that the webs partially protrude beyond an outer end of the support rail, particularly the collar. Thus, the webs cause the support rail to widen.

[0017] Preferably, the plurality of webs is arranged in a comb-like pattern. This allows the anti-displacement device to clamp different, even irregularly shaped, mounting devices. If a mounting device has a projection, the webs in this area will bend more toward the longitudinal axis of the support rail than webs in an area where the mounting device is flat or even has a recess. Depending on the number of webs and their dimensions, a very flexible anti-displacement device can be provided.

[0018] Furthermore, the webs can be arranged at a distance from one another. This allows the invention to adjust the clamping force. A larger distance between two webs results in a lower clamping force due to the increased material clearance. Thus, a distance between two webs can essentially correspond to the width of the webs, preferably less than 75% of the width of the webs, particularly preferably less than 50% of the width of the webs.

[0019] The bars can be arranged along the entire length of the anti-slip device, allowing clamping of one or more attachments over the largest possible area.

[0020] Preferably, an outer web is wider than an inner web. In this case, only one outermost web can be wider than all the inner webs. Alternatively, a web width can increase from the inside outward. This allows a clamping force to be adjusted over the length of the anti-displacement device, in particular, a clamping force can increase from the inside outward. Furthermore, an outer web can be designed to be more stable, preventing breakage and / or other damage, or at least reducing the likelihood of damage.

[0021] Preferably, the webs directly adjoin a lower edge of the collar when attached. This increases the clamping surface in the vertical direction, as the clamping begins directly below the collar. Directly adjacent here means that the webs just touch the lower edge, preferably a top side of the webs is spaced a maximum of 1 mm from the lower edge, and particularly preferably just not touching the lower edge.

[0022] The webs can have a square profile. In particular, the profile can be rectangular and have a length greater than a width. However, differently shaped profiles are also possible within the meaning of the invention, in particular adapted to a side surface of a mounting device facing the anti-displacement device. Preferably, the profile can be variable over the length of the webs, for example, tapering conically from the base body toward the tip of the webs.

[0023] Furthermore, it can be provided that the webs, in the attached position, protrude beyond the width of the support rail by less than 50% of the width of a profile of the webs, preferably by less than 25%, particularly preferably by less than 10%. This allows the clamping force of the clamp to be adjusted.

[0024] The anti-displacement device preferably has at least one projection designed to provide a positive and / or non-positive connection to the support rail. This enables the anti-displacement device to be positioned securely against displacement, particularly on a side surface of the support rail. For example, the support rail can have a recess complementary to the projection, into which the projection can engage when plugged in.

[0025] The projection can have a recess through which the projection provides the positive and / or non-positive connection. For example, the support rail can have a raised portion complementary to the recess of the projection, which, when plugged in, can engage in the recess of the projection, thus securely holding the anti-displacement device in place.

[0026] The base body preferably has a raised portion at an outer and lower end. The raised portion can, in particular, be designed to create a positive fit with a lateral profile of the support rail. This allows for better, and in particular more secure, positioning of the anti-displacement device. Alternatively or additionally, the raised portion can be designed to support the mounting device and / or to connect the anti-displacement device to a fastening system of the support rail in a force-fitting and / or positive-fitting manner.

[0027] Furthermore, the base body can have at least one spacer. The positioning of the anti-displacement device relative to the support rail can be adjusted via the at least one spacer. The spacer can be provided, in particular, on a side of the base body facing the support rail. The at least one spacer can also be used to adjust the extent to which the webs project beyond the width of the support rail.

[0028] Preferably, the at least one spacer is designed to be replaceable or adjustable, so that a distance between the anti-displacement protection and the support rail and thus a projection of the webs beyond the support rail can be adjusted.

[0029] The anti-displacement device preferably comprises a metal or a plastic. Thus, the anti-displacement device can comprise a polyamide, preferably a polyamide 6 or a polyamide 6.6. In particular, the anti-displacement device can be made of a material that is more flexible than the support rail and / or a mounting device. This allows for advantageous clamping, since the webs are flexible relative to the mounting device.

[0030] The invention further relates to a support rail comprising at least one anti-displacement device according to the invention. This allows the support rail to securely attach surface-mounted devices to the support rail.

[0031] The support rail preferably has two anti-displacement devices according to the invention, which are attached to opposite side surfaces of the support rail. Thus, a device mounted on the support rail is secured on both sides against displacement, particularly automatic displacement. The anti-displacement devices can thus be attached, particularly without tools.

[0032] In particular, the support rail has a projection or recess complementary to a projection of the anti-displacement device. This allows for the at least one anti-displacement device to be securely attached to or on the support rail.

[0033] The invention further relates to a method for attaching a mounting device to a support rail. The method comprises the following steps: - Attaching at least one anti-displacement device according to the invention to a support rail and - Attaching a surface-mounted device to the support rail.

[0034] This allows a surface-mounted device to be positioned securely on the mounting rail. The anti-displacement device can be plugged in, especially after the mounting rail has been prepared. Furthermore, it is preferably designed to be detachable and therefore flexible, for example, to be used at a different position on the mounting rail, on a different mounting rail, and / or for a different surface-mounted device.

[0035] Further details of the invention are explained with reference to the following figures. Fig. 1 an exemplary embodiment of an anti-displacement device according to the invention; Fig. 2 an exemplary embodiment of a support rail according to the invention with two anti-displacement devices according to the invention in a perspective view; Fig. 3 an exemplary embodiment of a support rail according to the invention with two anti-displacement devices according to the invention in a view from below; and Fig. 4 an exemplary embodiment of a support rail according to the invention with two anti-displacement devices according to the invention in a plan view.

[0036] Fig. 1 shows an anti-displacement device 1 for a device mounted on a support rail 100. The anti-displacement device 1 has an elongated base body 2 that can be plugged onto the support rail 100. For this purpose, the base body 2 has two projections 4 that are designed to provide a positive and non-positive connection with the support rail 100. In particular, the projections 4 each have a recess 5, via which the projection 4 provides the positive and non-positive connection, in that elevations 103 of the support rail engage in the recesses 5 when plugged on.

[0037] Furthermore, a plurality of webs 3 are arranged on the base body 2, which extend perpendicularly from the base body 2 and are designed such that, when the anti-displacement device 1 is plugged onto a support rail 100, they are positioned below a collar 101 of the support rail 100 and, at least in some areas, protrude beyond a width B of the support rail 100. Because the webs 3 protrude beyond the width B of the support rail 100 in an attached position, they widen the overall width of the support rail 100 and the anti-displacement device 1 and thus increase the clamping force acting on a mounting device.

[0038] The plurality of webs 3 are arranged in a comb-like manner here, and the webs 3 are spaced apart from one another. The distance between two webs 3 essentially corresponds to the width of the webs 3. However, in other exemplary embodiments not shown, the distance between the webs 3 can be smaller than the width of the webs 3. By adjusting the distance, the flexibility of the plurality of webs 3 can be influenced, since more or less material is available that can exert a clamping force on the mounting device. Furthermore, the distances can be arranged irregularly.

[0039] The webs 3 are arranged here over the entire length L of the anti-displacement device 1, so that the largest possible surface can be provided for clamping by the anti-displacement device 1. However, it can also be provided to provide webs 3 only in certain areas on the base body 2 of the anti-displacement device 1. For example, the arrangement of the webs 3 can be adapted to a side profile of a mounting device to be contacted by the webs 3.

[0040] The webs 3 here have a quadrangular profile. In particular, the profile is rectangular, and one length is greater than the other width. However, other profiles can also be implemented, so that, in particular, a side of the webs 3 facing a mounting device can be adapted to a side profile of a mounting device that is to be contacted by the webs 3.

[0041] In the Fig. In the anti-displacement device 1 shown in Figure 1, an outer web 31 is also wider than an inner web 32. Thus, the outer web 31 can be more stable than the inner web 32, making damage, particularly breakage, more difficult. This is because the outer web 31, in particular, can be subject to particular stress, especially if a mounting device is not attached centrally and, for example, partially protrudes beyond one end of the anti-displacement device 1.

[0042] The base body 2 here has a raised portion 6 at an outer and lower end. This raised portion 6 allows the base body 2 to achieve an improved positive fit with a complementary support surface 104 of the support rail 100. This allows for improved positioning of the anti-displacement device 1.

[0043] Furthermore, the base body 2 has an inwardly projecting edge portion 8. This edge portion 8 can, for example, engage behind a fastening system of the support rail 100 provided by rails 110 and thus secure the anti-displacement device 1.

[0044] The anti-displacement device 1 also has two spacers 7. These are formed on a side of the base body 2 facing the support rail 100. The spacers 7 can be used, in particular, to determine the spacing of the anti-displacement device 1 from the support rail 100 and thus the projection of the webs 3 beyond the width B of the support rail. A clamping force acting on the mounting device can thus be adjusted. Furthermore, the spacers 7 support secure positioning of the anti-displacement device 1 on the support rail 100 by exerting a counterforce on the recess 5 of the projection 4 and thus avoiding or at least reducing any possible play in the connection between the recess 5 and the elevation 103 of the support rail 100.

[0045] The webs 3 have a certain flexibility for clamping the mounting device, so that they yield slightly towards the support rail 100 when the mounting device is plugged in. This allows the anti-displacement device 1 to be used flexibly for different mounting devices, in particular for different side profiles of the mounting devices that are to be contacted by the webs 3, because the flexibility of the webs 3 allows the webs 3 to adapt to different side profiles.

[0046] For this purpose, it is provided that the anti-displacement protection 1, in particular the webs 3, comprise a metal or a plastic. Preferably, the anti-displacement protection 1 comprises a polyamide. Fig. The anti-displacement device 1 shown in Figure 1 is made in one piece from polyamide 6. Alternatively, the anti-displacement device 1 can also comprise polyamide 6.6. In this case, it is particularly provided that the material of the anti-displacement device 1 has greater flexibility than the support rail 100 and / or the mounting device. As a result, the webs 3 yield accordingly when the mounting device is attached, so that the webs 3 can advantageously adapt to a corresponding side profile of the mounting device for clamping the mounting device.

[0047] In the Fig. 2 to 4, an embodiment of a support rail according to the invention is shown, which has two anti-displacement devices 1 according to the invention. The anti-displacement devices 1 are attached to opposite side surfaces of the support rail 100. The Fig. 2 to 4 show the anti-slip devices 1 in an attached position from different views.

[0048] In the Fig. 2 shows that the webs 3, in the attached position, directly adjoin a lower edge 102 of the collar 101 of the support rail 100. Thus, the mounting device can be clamped vertically directly adjacent to the support rail 100.

[0049] Furthermore, Fig. 2 shows the support surface 104 of the support rail 100, on which the base body 2 rests in a form-fitting manner. The elevation 6 encompasses the end of the support surface 104 and thus provides a stop for simplified insertion of the anti-displacement device 1. Furthermore, the edge section 8 is visible, as well as a complementary edge section 105 of the support rail 100. The two edge sections 8, 105 have an aligned support surface, so that the support rail 100 and the anti-displacement device 1 can be attached to a fastening system, for example, rails 110, in a precisely positioned manner, particularly relative to one another.

[0050] Fig. Figure 3 shows the support rail 100 and anti-displacement devices 1 in a bottom view. This particularly clearly shows the positive and force-locking insertion of the anti-displacement devices 1. The support rail 100 has four protrusions 103, which, when inserted, engage in the recesses 5 of the two projections 4 of each of the two anti-displacement devices 1. The anti-displacement devices 1 can thus be secured to the support rails 100 by simply sliding them onto them.

[0051] To simplify sliding on, the projections 4 can be designed to be bevelled, for example, so that they can slide more easily over the elevations 103. Furthermore, the projections 4 here, as in Fig. 1, has a gripping edge 9 at its end. This makes it easier to release the anti-slip devices 1, as it supports gripping and slightly lifting the projections 4, for example, using a finger.

[0052] Fig. Finally, Figure 4 shows a top view of the support rail 100 and the two inserted anti-displacement devices 1. Here, the rails 110 of a fastening system to which the support rail 100 is attached are visible. Furthermore, the four edge sections 8 of the anti-displacement devices 1 are partially shown, which engage behind the rails 110 and thus support the secure insertion of the anti-displacement devices 1.

[0053] In particular, Fig. 4, the partial projection of the webs 3 beyond the width of the support rail 100 is visible. Thus, in the plan view, only a portion of the rectangular profile of the webs 3 is visible. In particular, less than 50% of the width of a profile of the webs 3 projects beyond the width B of the support rail 100. Preferably, the webs can also project beyond the width B by less than 25%, particularly preferably by less than 10%.

[0054] In the embodiment shown, the webs 3 have a width of slightly more than one millimeter, so that the webs 3 protrude a maximum of half a millimeter beyond the width B of the support rail 100.

[0055] The projection of the webs 3 is in Fig. 4 is indicated by dashed lines. This results in a total width D of support rail 100 and both anti-displacement devices 1, which is composed of the width B of the support rail and the projecting section of the profiles of the webs 3 of both anti-displacement devices 1. By attaching a mounting device, the webs 3 are pushed slightly inward, so that they apply a clamping force to the mounting device and secure the mounting device against displacement. The total width D thus decreases when a mounting device is attached.

[0056] The following steps can be used to attach a surface-mounted device to a mounting rail: - Connecting two anti-displacement devices 1 according to the invention to a support rail 100, as shown for example in the Fig. 2 to 4 shown, and - Attaching a surface-mounted device to the mounting rail 100.

[0057] The webs 3, which extend beyond the width B of the support rail 100, exert a clamping force on the attached mounting device. The mounting device can also have device locks against which the webs 3 can engage. The applied clamping force makes it difficult to move the mounting device and, particularly in vertical installations, can prevent the mounting device from shifting automatically.

[0058] For removal, the mounting device can be simply pulled off; no tools are required, as the clamping is automatic via the webs 3. The anti-displacement guards 1 are also designed to be removed without tools and can therefore be flexibly used on other support rails or for other mounting devices.

[0059] The features of the invention disclosed in the above description, in the drawings and in the claims may be essential for the realization of the invention both individually and in any combination, the scope of protection being determined by the claims.
