Device for fastening installation elements

The invention relates to a device for fastening installation elements such as pipe clamps, series clamps, installation ducts or similar holders for electrical installations in particular to profile rails, wherein the device consists of a slider which can be pushed onto mutually parallel areas of a profile rail and can be fixed to the profile rail in an immovable manner by means of a clamping element, wherein the installation elements are also held on the slider or are formed in one piece with it.

The profile rails to which the installation elements are to be attached can, for example, have a T- or I-shaped cross-section, whereby the web areas that are parallel to one another and aligned with one another are overlapped by corresponding elements,

OBO10669/92

or profile rails can also be provided, in which the web areas form a slot into which fastening elements can be inserted, whereby the fastening elements overlap the slot edges on the inside and outside.

Different designs are known in the state of the art. For example, it is known to fasten a C-profile rail using a sliding nut and a screw. It is also known to use a sliding nut with a welded-on threaded bolt, onto which, for example, a pipe clamp or series clamp with a welded-on nut can be screwed. Designs of fastening elements are also known in which lateral longitudinal grooves are provided in the base area, so that these elements can be inserted into the gap of a profile rail and pushed onto the legs of the rail facing each other. However, such elements are not suitable for vertical installation.

OBO10669/92

With the known devices, either the final fixation to a profile rail is provided by means of a screw and nut, or it is not possible to clearly define the fixation of the device, if it is only pushed onto the profile rail.

Based on this prior art, the invention is based on the object of creating a device of the generic type which enables fixing to profile rails while avoiding screws, nuts and similar fastening elements, while nevertheless allowing longitudinal displacement of the device relative to the profile rail for the purposes of assembly alignment.

To solve this problem, it is proposed that a spring-loaded locking tongue is mounted on the slide, the free edge of which is placed on the surface of the mutually parallel areas of the profile rail, whereby the locking tongue forms an acute angle with the surface of the profile rail.

OBO10669/92

With this design, it is possible to slide the slider in one direction onto the parallel areas of the profile rail, whereby the slider with the locking tongue is aligned so that the acute angle between the locking tongue and the surface of the profile rail is arranged at the back in the direction of displacement. The slider can thus be moved in one direction relative to the longitudinal direction of the profile rail, while the slider is locked in the opposite direction. Such sliders can be attached to profile rails in such a way that either the slider is pushed against a fixed support or two oppositely directed sliders are pushed from opposite sides of the profile rail (seen in the longitudinal direction) so that when they touch each other they are finally fixed relative to the profile rail. Subsequent displacement of the slider from the final target position is possible if the locking tongue is lifted manually or using a suitable tool from the surface of the profile rail, which is possible due to the spring elasticity of the locking tongue.

OBO10669/92

is possible. The locking tongue can consist of a spring plate. Appropriate installation elements can be integrally formed on the slide, for example pipe clamps, series clamps, installation ducts or the like, or such installation elements can be detachably attached to the slide, for example by means of a snap-in, screw, rivet or adhesive connection. This design of the fastening device enables forces to be absorbed that are comparable to those of a previously conventional connection using a sliding nut and screw. The locking tongue should be arranged in the fastening element in such a way that it is arranged at a steep angle (self-locking) relative to the corresponding support surface of the profile rail. The slide itself can be made of metal or plastic, as can the installation elements formed in one piece with the slide or in several parts.

The design according to the invention enables simple and extremely time-saving assembly, whereby the device, once fixed, cannot be shaken loose by vibrations, in contrast to screwed connections.

OBO10669/92

can be excluded.

Furthermore, it is possible to combine standard installation elements with the fastening device in the form of the slider with locking tongue, so that existing shapes and elements can be used, which is advantageous in terms of production costs.

A preferred further development is that the profile rail is designed as a C-profile rail and the mutually parallel areas are formed by their leg ends directed towards each other.

The use of C-profile rails is known in the state of the art.

Furthermore, it is preferably provided that the slide has insertion grooves for the parallel areas of the profile rail.

OBO10669/92

Particularly when using such sliders in C-profile rails, it is possible to either provide insertion grooves on the slider so that the slider can only be inserted into the profile rail from the front side and is held in position, with the final fixation being carried out by the corresponding locking tongue, or it is also possible, as is known in the state of the art, to provide the slider with a hammerhead-like projection so that the slider can be inserted into the gap in the profile rail with the hammerhead pointing in the longitudinal direction of the slot and is held on the rail by turning it by 90°. In this case too, the final fixation is carried out by the corresponding locking tongue.

Preferably, it is further provided that the locking tongue is part of a spring plate which is arranged in a cavity of the slide, wherein the spring plate has a first region which encompasses the parallel regions of the profile rail and is directed parallel thereto, a first region which runs perpendicular thereto on the opposite side

OBO10669/92

the side of the areas, the second area of which rests with its back on the cavity wall of the slider and has a third area bent at an acute angle from this, directed towards the parallel areas, resting on them at an acute angle, which represents the locking tongue.

In order to be able to release the locking tongue from the locking position very easily, a tool handle is provided on the locking tongue, near its free end.

In a further development, it is proposed that the tool handle runs approximately parallel to and at a distance from the parallel areas of the profile rail and has a tool engagement opening.

Of course, in order to access the locking tongue or the tool handle, it is necessary that the tool grip is accessible without any disturbing parts of the slide.

OBO10669/92

A preferred further development is that the locking tongue is designed as a leaf spring clamped on one side, which is arranged in the slider so that it can be bent in both possible movement directions of the slider.

For this purpose, it is advantageous if bending edges are formed between the clamping point and the free end of the leaf spring in the receiving cavity of the slider, on which the leaf spring is supported alternatively depending on the sliding direction of the slider.

In such an arrangement according to claims 7 and 8, the locking tongue designed as a leaf spring is directed relatively perpendicular to the sliding direction of the slide when the slide is not pushed onto a profile rail, whereby when the slide is pushed into a corresponding profile rail or when pushed onto a profile rail, the locking tongue is bent when it hits the corresponding areas of the profile rail.

OBO10669/92

is bent so that it allows the slider to be pushed in in the sliding direction. The edge of the locking tongue that rests against the profile rail locks against the sliding direction. This design enables the user to push the slider open in both possible sliding directions.

Furthermore, it is provided that the slide has wall openings as tool engagement for actuating the locking tongue.

In addition, it is intended that the slides can be pushed in the same direction against a fixed support or another slide that can be pushed in the opposite direction until they rest against one another.

The embodiments described above are particularly advantageous for the arrangement of series clamps, whereby the first series clamp in the insertion direction is inserted against a fixed support or against an oppositely oriented series clamp with a slider

OBO10669/92

and the other series clamps are pushed on in the same direction using the corresponding slider, so that the series clamps can be lined up and fixed to the profile rail.

Particularly in the case of pipe clamps and other installation elements, it is preferably provided that each slider holds two locking tongues which are directed at an acute angle to the parallel areas of the profile rail and are angled in opposite directions to one another in the sliding direction, with one of them resting on the parallel areas in a locking manner in one sliding direction and the other in the other sliding direction.

However, pushing such sliders onto a profile rail is only possible if the locking tongues are bent manually or using a suitable tool to such an extent that an insertion gap is formed for the corresponding areas of the profile rail. As soon as the slider has reached its target position,

OBO10669/92

the locking tongues are released so that they rest on the parallel areas of the profile rail.

A manufacturing-technically advantageous embodiment for this is characterized in that the locking tongues are formed by the legs of an approximately U-shaped spring plate which both enclose acute or obtuse angles with the base, whereby the base is supported on a wall of the cavity of the slider that is parallel to the parallel areas of the profile rail.

In this embodiment according to claims 11 and 12, it is particularly preferably provided that a tool is inserted or can be inserted into the slider, transversely to the sliding direction, by means of which the locking tongues are forced into a position in which their edge edges are spaced apart from the parallel areas of the profile rail.

OBO10669/92

The tool can have a fork-shaped end part for actuating the locking tongues. It is possible to form the tool by means of a fork-shaped tab, for example made of plastic, which is only used once and is inserted into the corresponding slider at the factory and is removed by the assembly person after it has been arranged in the correct place on the profile rail, thus ensuring that the slider is securely seated. Alternatively or additionally, the tool can also be designed as a fork-shaped key or the like that is reusable.

A preferred further development is further seen in that the slider has a hammerhead-like projection, which can be inserted into the gap of the profile rail between the areas, rotated by 90° and fixed in this position.

This makes it possible to use the slider not only in the longitudinal direction of the profile rail or the like, but the slider can also be used with existing

OBO10669/92

other installation, be inserted transversely into the rail and rotated in the corresponding
locked and positioned in the desired position.

A particularly advantageous further development is seen in the fact that the slide is essentially U-shaped, near its free leg ends on both side edges of each leg there is a
Slot, the slot width being at least
slightly larger than the material thickness of the
Cross-section C-shaped profile rail in the areas that a part of the legs cut free by a slot is cranked inwards relative to the other leg, namely on diametrically opposite edge edges of the legs, that immediately above the edge edges of the slot facing the base and at the same level, stops, in particular stop tabs, are formed or cut, which protrude outwards beyond the leg alignment, whereby the slider with legs directed parallel to the longitudinal slot of the profile rail in the slot

OBO10669/92

can be inserted until the stops are in contact with the areas and can be rotated by 90° from this position so that the areas of the profile rail engage in the open-edged slots on the edge of the leg of the slider .

With this design, it is also possible to subsequently insert the slider between existing installations that are already arranged on the C-profile rail or similar. The slider can be positioned accordingly and brought to the desired installation location in relation to the profile rail, partially inserted with its leg ends into the rail slot and then locked to the profile rail by turning it 90°.

It is considered particularly advantageous that a T-shaped spring plate is held in the U-shaped slider, which rests with its crossbar on the inside against the base of the U-profile, has retaining edges on the free ends of the crossbar, which are on the inside

OBO10669/92

on the legs of the U-profile, that the crossbar has a spring tab bent at approximately a right angle at both ends, which engages in a window cutout of the legs of the U-profile, that the longitudinal web of the spring plate forms the locking tongue supported on the areas of the C-profile rail, whereby the longitudinal web has a slot running from its free end to preferably over more than half its length, so that the longitudinal web forms two independently springy locking tongues.

As a result, when the slider is rotated to lock it to the C-profile rail, the locking tongue is activated in such a way that the area supported on one edge area of the C-profile rail is clamped in one direction and the area supported on the other edge area of the C-profile rail is clamped in the other direction, so that in the desired position, the effect of the two locking tongues prevents the slider from being moved in either of the two possible longitudinal directions along the rail.

OBO10669/92

It is particularly preferred that the slot of the longitudinal web of the T-shaped spring plate is approximately V-shaped with a rounded notch base.

In particular, for reasons of easier production, it is preferably provided that the longitudinal web is slotted in the middle at its cross-web end to form the T-shaped spring plate and the partial areas thus formed are bent in opposite directions by 90° to form the cross-web.

Furthermore, it is advantageous that at the base of the U-profile-like slider, next to the alignment line formed by the longitudinal web, a stop is bent towards the inside of the profile, which is arranged in the free space next to the bent area that forms the transverse web.

When the locking tongues spring open as intended, the stops form a counter-hold against which

OBO10669/92

the locking tongues can be supported with their end part, which is close to the crossbar, whereby the spring effect is reinforced.

The device for fastening installation elements, for example pipe clamps 1, series clamps 2, installation ducts 3 or similar holding elements for electrical installations to profile rails can be seen in the drawings. In all embodiments, the profile rails 4 are designed as C-profile rails, which have parallel

OBO10669/92

Have areas 5 onto which a slider 6 can be pushed. The slider 6 can be fixedly attached to the profile rail A by means of a clamping element described later. The corresponding installation elements (1, 2, 3) are attached to the slider 6 or are formed in one piece with it. A spring-loaded locking tongue 7 is held on the slider 6, which is made from a spring plate and whose free edge is placed on the surface of the mutually parallel areas 5 of the profile rail A. The locking tongue 7 forms an acute angle with the surface of the areas of the profile rail A. In the embodiments according to Figures 1 to 1A, the slider 6 has insertion grooves for the parallel areas 5 of the profile rail A. In the embodiment according to Figures 1 to 8, the locking tongue 7 is part of a spring plate which is arranged in a cavity 8 of the slider 6, which is formed relatively on the outside of the profile rail A. The spring plate has a parallel area 5 of the profile rail

OBO10669/92

under and parallel to it, a perpendicular to it (bent at a right angle) area 10 on the opposite side of the areas 5, which is supported with its back on the cavity wall of the cavity 8 of the slide 6 and a third area 11 bent from this at an acute angle, directed towards the parallel areas 5, supported at an acute angle on these, which represents the locking tongue 7. A tool handle 12 is formed and bent on the locking tongue 7 (area 11) near its free end or at its free end. The tool handle 12 runs approximately parallel to and at a distance from the parallel areas 5 of the profile rail 4 and has a tool engagement opening, as can be seen in particular from Figure 8. To release the locking position, it is only necessary to insert the tip of a slotted screwdriver into this tool engagement opening of the tool handle 12, whereby the locking tongue 7 is moved from the locking position into an unlocked position.

OBO10669/92

In this position, the slider 6 can then be moved relative to the profile rail 4 in the opposite direction to the sliding direction.

In the embodiment according to Figures 9 and 10, the locking tongue 7 is designed as a leaf spring clamped on one side, whereby this is arranged in the slide 6 so that it can be bent in both possible directions of movement of the slide. Between the clamping point 13 and the free end of the leaf spring forming the locking tongue 7, the arrangement of bending edges 14 is provided in the receiving cavity 8 of the slide 6, on which the leaf spring (locking tongue 7) is supported alternatively depending on the sliding direction of the slide 6. This design makes it possible to insert the slide both from the right and from the left into a corresponding profile rail 4. Since the design of the locking tongues 7 according to embodiments 1 to 11 only locks in one direction, it is advantageous if the slide 6 is pushed against a fixed support, so that the loading

OBO10669/92

fastening position is finally fixed, or it is possible, as shown in Figure 1, for example, to use a slider as a fixed support against which the sliders of other installation elements are then pushed in opposite orientation. This locks the position of all sliders 6 relative to one another. This is particularly clear in Figure 1, the bottom three sliders 6.
In the embodiment according to Figure 11, the slide

6 a support for a cable duct 3 is formed, wherein the cable duct can be connected to the slide 6 in a suitable manner, for example by means of snap-in connections, as shown in Figure 11.

In the embodiment according to Figures 12 to 15, each slider 6 has two locking tongues directed at an acute angle to the parallel areas 5 of the profile rail 4

7, which are angled in opposite directions to each other in the sliding direction. Thus, one of them rests in one sliding direction and the other in the other sliding direction on the parallel areas

OBO10669/92

5. The locking tongues 7 are formed by the legs of an approximately U-shaped spring plate 15, which encloses both acute or obtuse angles with the base of the spring plate, whereby the base is supported on a wall of the cavity 8 of the slide 6 that is parallel to the parallel areas 5 of the profile rail 4. As can be seen in particular from the illustrations according to Figure 14 and

15, a tool 16 can be inserted into the slide 6 or into its cavity 8 transversely to the sliding direction of the slide 6, by means of which the locking tongues 7 can be pushed into a position in which their edge edges are spaced from the parallel areas 5 of the profile rail 4. In addition, the slide 6 can have guide grooves 17 for the fork-shaped ends of the assembly tool 16. In the embodiment according to Figure 14, the fork tines of the tool grip

16 between the side walls of the slide 6 and the locking tongues, whereby these are moved towards each other and are transferred to an unlocked position. In the embodiment according to Figure 15, the fork tines grip

OBO10669/92

of the tool 16 between the slide 6 (in the area of the guide grooves 17) and the locking tongues, so that the locking tongues are bent away from each other, into a position in which they have no contact with the corresponding areas 5 of the profile rail 4.

In the embodiment according to Figure 15, the slider 6 is provided with a hammerhead-like projection 18, which can be inserted into the gap of the profile rail 4 between the areas 5 and can be moved into its desired position by rotating it through 90°.

A further, particularly preferred embodiment is shown in Figures 16 to 24. The slider 6 is essentially U-shaped, as can be seen in particular from Figures 16 to 19. A slot 21, 22 is provided near its free leg ends on both side edges 19 of each leg 20. The slot width is slightly larger than the material thickness of the profile rail 4, which has a C-shaped cross section, in the areas 5. In each case, a slot

OBO10669/92

21, the part of the legs 20 cut free is bent relatively inwards towards the other leg 20. The bent is designated 23. The bents 23 are arranged on diametrically opposite edges of the legs 20. Immediately above the edge of the slots 21, 22 facing the base 24 and at the same level, stop tabs 25 are cut and bent, which protrude outwards beyond the alignment of the legs 20. These stop tabs serve as a limiter when inserting the slider into the slot of the C-profile rail 4. The slider 6 can, as can be seen in particular from Figure 24, be inserted into the slot of the rail with legs 20 aligned parallel to the longitudinal slot of the profile rail 4 until the stops 25 rest on the areas 5 and from this position can be rotated by 90° around the vertical axis of the slider so that the areas 5 of the profile rail 4 engage in the open-edged slots 21, 22 on the leg edges of the slider 6. The end position is on the right in Figure 24

OBO10669/92

while the insertion position is shown in Figure 24 on the left.

A T-shaped spring plate 26 is held in the U-shaped slider 6, which rests with its crossbar 27 on the inside against the base 24 of the U-shaped profiled slider 6, as can be seen in particular from Figure 17. The spring plate 26 has holding edges 28 on the free ends of the crossbar 27, which are supported on the inside on the legs 20 of the U-profile, as can again be seen in particular from Figure 17.

The crosspiece 27 also has a spring tab 29 bent at approximately a right angle at both ends, whereby the spring tabs 29 each engage in a window cutout 30 of the legs 20 of the U-profile in a locking manner, as can again be seen particularly clearly in Figure 17. The spring tabs 29 are aligned slightly diverging from one another in order to engage in the corresponding openings 30 and lock there.

OBO10669/92

- 29 to be able to support.

The longitudinal web 31 of the spring plate 26 forms the locking tongue 7 which is supported on the areas 5 of the profile rail 4, as can be clearly seen from Figure 17 and Figure 23.

The longitudinal web 31 is provided with a slot 32 running from its free end to more than half its length, so that the longitudinal web 31 forms two independently resilient locking tongues 7 that can spring in opposite directions. This ensures that during the movement sequence as shown in Figure 24, one of the two locking tongues 7 thus formed deforms in one direction and the other in the other direction, thus forming a two-sided lock against longitudinal displacement of the slide 6 along the profile rail 4.

As can be seen in particular from Figure 22, the slot 32 of the longitudinal web 31 of the T-shaped spring

OBO10669/92

sheet 26 is approximately V-shaped with a rounded notch base.

To form the T-shaped spring plate 26, the longitudinal web 31 is slotted in the middle at its cross-web end and the partial areas thus formed are bent in opposite directions by 90° to form the cross-web 27, as can be seen in particular from Figure 21.

In addition, on the base 24 of the U-profile-like slider, next to the alignment line 33 formed by the longitudinal web 31, a stop 34 is bent towards the inside of the profile, which is arranged in the free space next to the bent area that forms the transverse web 27.

To assemble the individual parts, the spring plate 26 can be inserted into the U-profile-like slider 6 and locked into place. The slider 6 can then be inserted into the profile rail 4 in the position shown in 24 (left position).

OBO10669/92

whereby the stops 25 are supported on the areas 5 of the C-profile rail. The slider 6 can then be rotated clockwise by 90° in the embodiment according to Figure 24 due to the offsets 23 and the slots 21, 22, so that the areas 5 of the profile rail 4 engage in the slots 21, 22 and the locking tongues 7 rest against each other in a locking manner on the areas 5 of the profile rail. It is not possible to rotate the slider 6 beyond 90° because the edges of the areas 5 of the profile rail 4 rest against the slot base and the lack of offset on the other two legs means that there is no longer any possibility of movement.

The invention is not limited to the embodiments, but is variable in many ways within the scope of the disclosure.

All new individual and combination features disclosed in the description and/or drawing are considered essential to the invention.
