Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a suspension device for fastening a duct housing with a blind package according to the preamble of claim 1.

BACKGROUND OF THE INVENTION

The installation of Roman blinds is often carried out in two stages. First, hangers for the store are attached above a window. Then a blind package, which is normally already fixed in a duct housing upon delivery, is mounted in the suspension using a duct housing. Common systems include hangers that provide clip closures for secure hanging, such as in the disclosures EP2500507A2 or JPS57124599U shown. Other systems are based on a suspension without an additional locking bracket, such as in the disclosure EP1617037A1 or the disclosure JPS5717396U shown. The suspension of the revelation EP1617037A1 includes a spring to fix the housing of the blind package. The suspension of the revelation EP1617037A1 includes a hinged side bar, which is kept closed by spring pressure to fix the housing of the blind package.

A disadvantage of devices that have been customary up to now or the aforementioned devices is that the assembly effort can be relatively high. The reasons are different, for example screws must also be screwed in at the second stage and / or at least two fitters must be on site because more than two hands are needed to be able to carry out a safe assembly. For example in the system according to the disclosure EP1617037A1 Due to the spring force to be overcome during assembly, it is advisable to carry out assembly together by at least two fitters and in the system according to the disclosure EP2500507A2 or with other systems with a locking bracket, it is also advisable to do the assembly at least in pairs.

TASK

It is therefore an object of the present invention to provide an alternative device which generates the least possible assembly effort. The main aim is a device that can be assembled by a single person within a very short time. In particular, the aim is to use screws or other anchors, particularly e.g. to be able to mount the blind package without anchoring in or on the duct housing.

DESCRIPTION OF THE INVENTION

This invention fulfills the foregoing requirements by providing a suspension device for securing a duct housing with a blind package.

The suspension device includes at least one assembly web, by means of which the suspension device can be attached to an object, and at least a first carrier and a second carrier, which form at least one pair of legs protruding from the assembly web, each with a first catch hook on the first carrier and on the second carrier is designed for gripping the channel housing, preferably on its rolled edges. The suspension device is characterized in particular by the fact that at least one of the carriers or the first carrier has a second catch hook for gripping the channel housing. In a first step, in particular, the second catch hook allows the channel housing to be clicked into a secure but still displaceable position in the device before the rolling edges of the channel housing are placed in the first catch hook from the second catch hook in a second step. The duct housing sits in the first Catch hooks of the two carriers of a pair of carriers, the clamping by the device is stronger overall, so that the channel housing can usually hardly be moved against the suspension device under normal conditions of use and is thus fully installed.

The suspension device is essentially U-shaped. The carriers can be referred to as legs of the U-shaped device. The limb or the limb pair expediently serves to clasp the channel housing in at least one cross-sectional plane.

The assembly web and carrier of a pair of legs together define a duct housing receptacle. It can be said that the channel housing receptacle is formed on the inside of the device.

The advantageous design variants listed below lead, alone or in combination with one another, to further improvements of the suspension device.

The first carrier and the second of the carriers expediently each have a second catch hook for gripping the channel housing. This further increases the safety and flexibility when installing the duct housing.

The respective first catch hook and the respective second catch hook are expediently formed on the inside of the carrier or on the inside of the leg on the carrier. The respective first catch hook is preferably formed directly on the respective carrier, while the respective second catch hook is formed on the respective first catch hook (that is, the respective second catch hook is only formed indirectly via the first catch hook on the carrier). The catch hooks thus reach into the space between the carriers. By means of catch hooks designed in this way, a profile part introduced between the carrier or leg can be gripped, in particular by snapping into the catch hook. The catch hook is preferably designed as a snap hook. So that the free profile edges of a channel profile housing can snap into the catch hook, the shape of the catch hook and the shape of a profile part are matched to one another.

In addition, a certain elasticity of the carrier or of the carrier material is assumed.

It is advantageous if the second catch hook of a carrier connects to the respective first catch hook of the same carrier and / or the two first catch hooks of a pair of legs (or pair of carriers) together allow the channel housing to be more closely enclosed (i.e. clasped) by the carrier than the two second catch hook or a combination of the first catch hook of one of the carriers with the second catch hook of the other of the two carriers of a pair of legs (or pair of carriers).

For grasping a channel housing, the first catch hooks expediently protrude into the space spanned by the two legs or by the pair of legs. A second catch hook or a second catch hook preferably connects to one or each of the first two catch hooks, and projects further into the space than the first or the respective first catch hook. In other words, the second catch hook of a carrier expediently adjoins the inside (i.e. starting from the first catch hook further inwards into the space between the carriers or between the legs) to the respective first catch hook of the same carrier. The respective second catch hook of a carrier is offset inwards in a particularly expedient manner parallel to the first catch hook.

The second catch hook in each case expediently has a greater distance from the assembly web than the first catch hook in each case. In other words, the second catch hook is expediently offset from the first catch hook (i.e. especially from the assembly web, which is located above the catch hook, offset downwards).

In particular, the second catch hook is advantageously offset inwards and downwards relative to the first catch hook. Moving down means at a greater distance from the assembly bridge.

It is expedient that the first catch hook in each case has a first holding projection and the respective second catch hook in each case has a second holding projection.

The first catch hook in each case expediently arises from the inside of the leg on the carrier and merges into the respective first retaining projection. The first retaining projection defines the end of the first catch hook.

The first catch hook in each case expediently merges under the first holding projection in each case in the second catch hook. The two holding projections, i.e. the first holding projection and the second holding projection define the beginning and end of the second catch hook.

The first catch hook is expediently designed as a curved extension of the respective leg, whereby the first catch hook is a (direct) extension of the carrier.

The second catch hook is designed as a further curved extension, whereby the second catch hook is an extension of the first catch hook and thus an (indirect) extension of the carrier.

It is preferred that each carrier has a guide flap at each end of the leg, which is equipped with a grip nose for manual gripping of the respective carrier and is optionally equipped with a guide bevel to facilitate the insertion of the channel housing.

The surface of the guide bevel of the guide tab expediently leads to the second holding projection or, if there is no second catch hook, to the first holding projection.

It is advantageous that on the inside of the device at least one press stud is formed opposite the catch hook, so that the channel housing can be clamped between the first catch hook and the at least one press stud.

It is particularly advantageous that in each case at least one press stud on at least one carrier of a carrier pair, preferably on each of the carriers of a carrier pair is formed opposite to the first catch hook, so that the channel housing can be clamped between the first catch hook and the pressing knob opposite it.

It is expedient for the first carrier and the second carrier to be arranged in a mutually mirror-image arrangement, essentially projecting in the same direction from the assembly web.

It is expediently provided that the respective carriers of a pair of legs have a prestress in a relaxed position with respect to a channel housing to be inserted between them.

The mounting web advantageously has a mounting structure (such as, for example, a central borehole), which is used for mounting by means of an anchoring (such as, for example, using a screw passed through the borehole).

On the one hand, the suspension device can be formed in one piece, in particular in such a way that the assembly web and carrier are designed as integral areas of the device.

On the other hand, the suspension device can be constructed in several parts, in particular in that the carriers and the mounting web are designed as separate device elements (component elements) (for example at least the carriers as the first carrier element and second carrier element and the mounting web as the mounting web element. Advantageously, the respective device elements have connection structures by means of which the elements can be fastened to one another The connection structures are designed, for example, as interlocking plug connection structures.

A mounting web element, which is connected, in particular latched, to at least one first carrier or carrier element and a second carrier or carrier element, ie a pair of carriers or carrier elements, expediently forms a web spacing the two carrier elements between the two carrier elements.

Advantageously, at least two support elements can be plugged onto a mounting web, preferably in such a way that they can be plugged on with little effort, but the plug connection cannot be loosened or can only be loosened with great effort, e.g. in that the connection structures on the support element and assembly web with mutual snap-in structures, e.g. Trough and barb are equipped.

A carrier element is advantageously characterized in that the first and optionally the second catch hook are formed on a first end of the carrier element, while the structure for fastening the carrier element on the assembly web element is formed on a second end of the carrier element. The structures for fastening the carrier elements to the mounting web element are in particular designed such that the direction of attachment between the carrier element and the mounting web element is oriented essentially perpendicular to the load-bearing force on the catch hook. This ensures that the support elements cannot detach from the assembly web element due to the weight of the channel profile housing. With regard to the practical application orientation of the suspension device, a plug connection between the carrier element and the assembly web is thus advantageously carried out with an essentially horizontally oriented plug-on direction.

The suspension device can be made in one piece (11) from a plastic material, e.g. made by injection molding. Alternatively, a version made of metal (such as steel, in particular e.g. spring steel) is also conceivable. The plastic material may be fiber reinforced for reinforcement, e.g. glass fiber reinforced.

In the multi-part suspension device design, the supports or support elements are advantageously made of a plastic material (e.g. advantageously of a fiber-reinforced plastic), while the mounting web or the mounting web element is made of a preferably more rigid material, e.g. metal (such as steel, especially spring steel) is. Carrier or carrier elements can alternatively be made of spring steel.

In particular when the catch hook is designed as a snap connection, the elasticity of the material (mostly plastics or alternatively spring steel) from which the carrier or the carrier element is made is used.

The multi-part suspension device is characterized in one embodiment in that preferably at least one pressure knob is formed on each support element in opposition to the first catch hook of the support element, so that the channel housing can be clamped between the first catch hook and the pressure knob of a support element. Each carrier element thus clamps the channel housing in a substantially vertical direction, to the left and right of the channel housing. In addition, the channel housing is gripped in a horizontal direction by the interaction of the two carrier elements of a pair of legs and is preferably clamped due to a pretension of the suspension device with respect to the channel housing cross section.

It is particularly advantageous that a first catch hook is formed on a carrier element in opposition to one another and the distance between the catch hook and the press stud is dimensioned such that the channel housing is clamped between the first catch hook and the press stud opposite it.

Furthermore, a set for fastening a duct housing with a blind package is disclosed. The set includes one or more suspension devices, preferably two suspension devices, one or more blind guide rails, preferably two blind guide rails, at least one channel housing and preferably at least one blind package. The duct housing is conveniently supplied with an integrated blind package.

The optional features mentioned can be implemented in any combination, provided that they are not mutually exclusive. Particularly where preferred ranges are given, further preferred ranges result from combinations of the minima and maxima mentioned in the ranges.

Further advantages and features of the invention result from the following description of the invention with reference to exemplary embodiments.

DETAILED DESCRIPTION OF THE FIGURES

In the following, identical reference numerals stand for identical or functionally identical elements (in different figures). An additional apostrophe can be used to distinguish functionally identical elements (in the same figure).

In 1 and 2 A first embodiment of a suspension device 11 according to the invention is shown. In practice, at least two or more suspension devices 11 are normally required to hang an elongated duct housing on the building.

The suspension device 11 is essentially U-shaped, with an upper mounting part 13 (also called a mounting web) and two legs 15, 15 '(also called a carrier), which attach laterally, in particular at the end, to the mounting part. Alternatively, the suspension device 11 can essentially also be regarded as a two-leg, downwardly open bracket or as a two-leg bracket. The legs 15, 15 'point essentially in the same direction away from the assembly part, in particular each with an angle between the assembly web and the substantial leg extension of approximately 90 degrees or preferably less than 90 degrees (for example in the range from 80 to less than or equal to 90 degrees, further preferred) from 85 to <= 90 degrees, more preferably from 87 to <= 90 degrees), so that the legs are, so to speak, preloaded against a channel housing 53 to be inserted between the legs (or the distance between the legs decreases slightly with increasing leg extension), so that due to the preload, the channel housing 53 from both sides or by the legs of the suspension device 11 a received in the suspension device 11 Channel housing 53 is clamped. The leg ends are equipped with catch hooks 17, 19. This results in particular in a supporting function of the legs. At least one of the two legs is equipped with two catch hooks 17, 19; preferably both or each of the two legs is equipped with at least two catch hooks 17, 19. The catch hooks 17, 19 of the two legs 15 are directed inward or arranged on the inside of the leg, in particular in such a way that the catch hooks 17, 19 of one leg 15 form a constriction together with the catch hooks 17 ', 19' of the other leg 15 '. Mounting part 13, legs 15 and catch hooks 17, 19 are in particular designed in such a way that the suspension device 11 can receive, grasp and possibly clamp a channel housing 53 in its cross-sectional plane. The catch hooks are designed to grip the end longitudinal edges 55, 55 'of a duct housing 53, the end longitudinal edges 55, 55' of the duct housing 53 snapping into the first or second catch hooks 17, 19 of a leg 15 either selectively or randomly when a duct housing is pushed in. The legs 15, 15 'are designed to a certain extent to be elastic, for example made of an elastic material, so that their mutual distance can be changed elastically by pressure.

On each leg 15, two catch hooks 17, 19 are preferably designed as double catch hooks, so to speak. In particular, the first catch hook 17 arises on the inside of the leg 15 and leads into a first holding projection 25, which is preferably directed towards the assembly web, while the second catching hook 19 rises from the first catching hook 15 under the first holding projection 25 and into a second holding projection 27, which preferably also Is directed towards the assembly part. In a particularly preferred embodiment, the first catch hook 17 is higher than the second catch hook 19; that is, the distance to the mounting part is smaller for the first catch hook 17 than for the second catch hook 19, in particular such that a channel housing 53 is fully clamped between the first catch hook and the mounting part, but a channel housing 53 between one of the second catch hooks and the mounting part is only with play hangs in the second catch hook towards the mounting part and can thus be moved in the longitudinal direction of the duct housing. If at least one of the end longitudinal edges 55, 55 'of a duct housing 53 only hangs in the second catch hook 19, the duct housing is securely gripped and held by the suspension device 11, but there is a lateral displacement along the longitudinal orientation of the duct housing still easily possible. This is useful in order to correctly position the channel housing 53 and thus the blinds before the channel device 53 is gripped by the suspension device 11 so that it cannot move (or slip) by snapping into the two opposite first catch hooks 17, 17 '.

So that a channel housing 53 can be gripped securely by the first catch hook, the dimensions of the channel housing 53 and the suspension device 11 are matched to one another accordingly. In particular, the distance between the first catch hook 17, 17 'and the mounting part 13 corresponds approximately to the height dimension of a duct housing 53. Appropriately, the distance between two opposing unloaded legs 15, 15' preferably corresponds to the width dimension of a duct housing 53. However, it is advantageous if the Legs 15, 15 'have a slightly decreasing mutual distance in increasing leg length, as a result of which a slight clamping effect on the longitudinal sides of the channel housing 53 is achieved.

Expediently, pressing knobs 29 are provided on the inside of the suspension device on the mounting part 13, which press on the duct housing roof 57 when the duct housing 53 is gripped by the first catch hooks 17, 17 '. In this case, the duct housing roof 57 is pressed in slightly, which leads to a further increase in the clamping effect by the suspension device 11. If, on the other hand, the duct housing 53 is gripped by at least one of the second catch hooks 19, 19 'or both second catch hooks, the corresponding pressing knob 29 presses the duct housing roof 57 less or not at all.

The respective second catch hook 19, 19 'of the respective leg 15, 15' of the suspension device 11 connects to the respective first catch hook 17, 17 'of the same leg 15, 15'. The two first catch hooks 17, 17 'together allow a narrower enclosure of a duct housing 53 by the legs 15, 15' than the two second catch hooks 19, 19 '. In particular, the suspension device 11 is designed in such a way that the second (or in particular lower) catch hooks 19 and 19 'in the suspension device 11 are set closer together than the first (or in particular upper) catch hooks 17, and 17'.

Furthermore, each leg 15 expediently has a grip tab 31, by means of which either the first catch hook 17 or the second catch hook 19 can be used to grip the end longitudinal edge 55, 55 'and, if appropriate, clamps. The grip tab 31 preferably points overall obliquely downwards and outwards in the appropriately mounted suspension device 11 so that the grip tab 31 can be operated by hand in order to snap a channel housing 53 into the desired catch hook after a first insertion into the suspension device 11, e.g. in a situation when the suspension device 11 is installed on the building above a window.

The surfaces of the suspension device 11 leading out of the receiving area 35 between the second catch hook 19, 19 'or the second holding projection 27, 27' and grip tabs 31, 31 'can be designed as a guide surface 33, 33' in such a way that the guide surfaces 33, 33 'of a pair of legs 15, 15' create a tapered inlet area 34, so that a duct housing 53 can be pushed into the receiving area 35 of the suspension device 11 as easily as possible (preferably by a single fitter).

The assembly web 13 is essentially designed as a straight web which connects the spaced leg regions 15, 15 'or connects the legs 15, 15' spaced apart. An attachment structure 37, e.g. one or more bores in the assembly web 13 serve to fasten the suspension device 11 by means of screws or other anchoring means to the building. The suspension device 11 can be installed on the structure via the fastening structure 37 before a duct housing 53 with blinds is inserted into the preinstalled suspension at a later time and assembled ready for use.

The suspension device 11 in 1 and 2 is made in one piece. Such a device can be produced, for example, by injection molding from a plastic material.

In 3 and 4 A second embodiment of a suspension device 111 according to the invention is shown. This alternative design is made up of several parts. The two legs 115, 115 'each form a plug-in part which terminates on a web 113 are attachable. The individual parts are in the exploded views of the 5 and 6 as well as the detailed drawings of the 7 and 8 shown. The leg parts 115, 115 '- as already above in relation to the first embodiment in 1 and 2 described - are preferably equipped with a first and a second catch hook 117, 117 ', 119, 119', adjoining grip tabs 131, 131 'and in relation to the catch hooks molded pressure knobs 129, 129.

In addition, the clip-on leg parts 115, 115 'are expediently equipped with plug-in receptacles 139 for fixed attachment to the web 113. So that the leg parts 115, 115 'remain fixed on the web, the plug-in receptacles 139 are provided with retaining knobs 141 ( 7 and 8 ) equipped in corresponding depressions 143, 143 'in the assembly web 113 ( Fig. 5 ) snap in. For this purpose, the assembly web 113 is designed with at least one depression 143 or a further bore at the end. To make it easier to attach the leg parts 115, 115 'to the mounting web 113, the mounting web can each have a broken edge 145, 145' on the leg side, so that the retaining knob 141 of the plug-in receptacle 139 can be pushed onto the mounting web 113 relatively easily.

The web 113 can e.g. made of a metal, e.g. Steel. As a result, the assembly web has the necessary strength and rigidity to fasten the suspension device 111 to the building, in particular by means of the bore 137 and a suitable anchoring means. The legs 115 and 115 'are preferably made of an injection molded plastic. As a result, the legs 115, 115 'have a certain elasticity, which is particularly advantageous for the intended snap connection around a channel housing 53.

In 9 and 10 A third embodiment of a suspension device 211 according to the invention is shown. In contrast to the second embodiment, the assembly web 213 is provided with a central thickening 247. The transition 249 to the central thickening 247 is designed, for example, as a step and forms the end of the plug connection area 251 of the assembly web.

The suspension device 11 is used for the quick and screwless assembly of a blind package, which is composed of the channel housing 53 and the blinds contained therein.

To assemble a blind, the suspension device 11 is first installed in a window opening on the building. The suspension device 11 is expediently attached to its mounting structures 37, e.g. Holes, anchored in a window opening by means of screws or other anchoring means.

A duct housing 11 with blinds contained therein can then be pressed into the suspension device 11 quickly and easily by a technician. It is not necessary to set screws or other anchors. Only for systems with side rails for the blinds, the side rails for are now to be fixed with screws on the sides of the window opening.

The invention is explained below on the basis of application examples.

APPLICATION EXAMPLE 1

In 11 to 14 the mode of operation of a suspension device 311 according to the invention is shown using the example of the third suspension device version. In 11 and 12 A ready-to-use assembled device 311 with a channel housing 53 inserted in the device 311 is shown. The channel housing 53 is carried on its rolling edges 55, 55 ', on one side by the first or outer catch hook 317' and on its second side by the second or inner catch hook 319. In this position, the channel housing 53 hangs securely in the catch hook 317 , 317 ', 319, 319' of the two legs 315, 315 ', but without being fully pressed against both pressure knobs 329, 329'. In addition, there is still a great deal of play between the walls of the channel housing 53 and the suspension device 311, since the accuracy of fit between the walls of the channel housing 53 and the suspension device 311 is not optimal as long as at least one of the two legs 315, 315 '(here the left leg 315) in the catch hook 319, 319 'remote from the leg and thereby channel housing walls and suspension device surfaces are essentially not aligned in parallel and are essentially not arranged adjacent to one another, but in the present case are even aligned obliquely to one another. In this arrangement, the frictional connection between the channel housing 53 and the suspension device 311 is not optimal, rather the channel housing 53 is still displaceable relative to the suspension device 311. In this position, a blind fitter can position the channel housing without further help, i.e. alone, against the suspension devices 311 (if these are at the Buildings are anchored (not shown here)) move in the longitudinal direction of the duct housing and bring them into their working position (ie placed in the middle of a window pit, for example).

As soon as the duct housing is optimally positioned, the fitter grips one or both grip tabs 331, 331 'of a suspension device 311 and hangs the rolling edge (s) in the first catch hooks 317, 317', if they are not already, in an arrangement such as in 13 and 14 to achieve. Here, the channel housing walls and suspension device surfaces (ie the leg surfaces) are aligned essentially parallel and are arranged essentially adjacent to one another, so that the best possible frictional connection between the channel housing wall (at least the channel housing side walls) and the suspension device is produced. The pressure knobs of the suspension device preferably press against the duct housing roof in order to additionally achieve a clamping between the pressure knobs and the second catch hook. The rolled edges are also pressed into the first catch hooks 317, 317 'due to the pressure of the nub, which leads to additional frictional engagement between the first catch hooks and the rolled edges 55, 55'.

A channel housing 53 is preferably provided on the channel side walls with longitudinal notches 59 in order to give the elongate channel housing stability.

Normally, at least two suspension devices 311 per channel housing are anchored in a window pit in the building. The at least two suspension devices are arranged in the same direction spaced apart from one another on a straight line.

In practice, four or more suspension devices 311 are often installed to assemble heavy and or particularly long blind packs or duct housings or more complex hanger designs with more than one pair of legs per hanger. An example of such a suspension device is shown in the following application example.

APPLICATION EXAMPLE 2

This in Fig. 15 Multi-part plug-in suspension device concept described enables fast and screwless installation of blinds or blind packages on the building. The blinds are packed in channel housings 53, ie supplied as a blind package. For assembly, the blind package only has to be installed in a window opening. Suspension devices 11, 211, 311, 411 are usually provided for this. A channel housing 53 is usually designed as a three-walled longitudinal profile, in particular made of sheet metal. The two longitudinal terminations of the longitudinal profile are expediently bent inwards (ie towards the profile cavity) to form a curve and are also called rolling edges 55, 55 'here.

The suspension device 411 according to the invention shown here is used to retract and latch the bent-in rolling edges 55, 55 'into the left and right catch hooks 417, 417', 419, 419 'of the individual support elements 415, 415', 415 ", 415". The support elements 415 are designed with plug-in recesses 439, by means of which the support elements 415 can be pushed or attached to the mounting carrier extensions 414 on the mounting web 413.

In this example, the assembly web 413 is embodied as a multiple web, so to speak, which has connector connections 412 for not only one pair of carrier elements 415, 415 'but for two pairs of carrier elements 415, 415' and 415 ", 415 '". The assembly web 413 has in particular an elongated plate with (in the plane of the plate) four laterally projecting assembly extensions 414. Appropriately, two assembly extensions 414 are arranged in pairs facing away from each other on the left and right of the elongated plate. Several pairs of mounting extensions, according to Fig. 15 in particular two pairs, are arranged at a distance from one another over the length of the plate or are formed thereon. Plates with more than two pairs of assembly extensions are conceivable. In particular the two or more pairs of assembly extensions, each of which forms a so-called simple web, are arranged in the plate plane transverse to the longitudinal orientation of the plate. In other words, a multiple web such as 413 could also be described in such a way that two or more simple assembly webs 113, as in 5 and 6 shown, are connected to one another in a spaced-apart sequence via a cross connection.

A pair of mounting extensions and the plate section between them form a simple web, comparable to a web 313 as he the 3 and 4 is shown.

The support elements 415, 415 ', 415 ", 415" which are expediently designed identically for all positions 412 provided on the mounting bracket 413 expediently have fixing knobs 441 in the plug-in recesses 439, which can also be designed as barbs or plug pins or the like. The fixing knobs 441 snap into the correspondingly designed recesses 443 in the mounting bracket 413 when plugged in. By means of the fixing knobs 441 on the support elements 415 and the corresponding recesses 443 on the mounting bracket 413, the supporting elements 415 on the mounting bracket 413 can be fixed in a predefined end position 412. This safety measure prevents detachment from the assembly bridge 413.

The support elements 415 can be fixed on the assembly web 413 in such a way that they form two legs, the mutual distance of which in the straight region 416 to the end of the leg expediently decreases, namely to a dimension which is less than the width of the channel housing 53, in particular less than the width of the channel housing 53 close to its rolling edge 55, which conveniently acts as a preload for clamping the channel housing 53.

Upper catch hooks 417, 417 'and lower catch hooks 419, 419' formed on the support elements 415 are adapted in shape to the rolling edges 55. The catch hooks 417, 419 are shaped in particular in such a way that they grip around the channel edges 55 and thus can grip around the channel housing 53 as a whole.

On the mounting web side, the support elements 415 have inward pressing knobs 429. The press studs 429 work in conjunction with the upper ones Catch hook 417 clamps on the duct housing 53, in that the distance between a press stud 429 and the respective upper catch hook 417 corresponds to the dimension of the duct housing 53 (ie the dimension from the rolling edge 55 to a point on the duct housing roof 57 which lies below the press stud 429) comes) corresponds or is slightly smaller than the aforementioned dimension of the channel housing 53. Conveniently, the suspension device 411 has dimensions such that a channel housing 53 can be clamped between the pressure knob 429 and the upper catch hook 419 such that the channel housing 53 is light under the pressure of the pressure knob 429 is bent (see also 13 and 14 ). Due to the deflection, a force is exerted on the channel housing 53, as a result of which the channel housing 53 is held particularly well by the suspension device 411.

In the insertion area of the suspension device 411, insertion guides 433, 433 'are formed on the ends of the support elements 415 for the duct housing assembly. The insertion guides 433, 433 'are e.g. designed as sliding surfaces at the lower end of the respective support element 415, the left and right insertion guides 433, 433 'of a support element 415 in a spaced apart arrangement forming a funnel-like constriction for inserting the channel housing 53.

Furthermore, the support elements 415 can be equipped with grip tabs 431, by means of which the support elements 415 for mounting and dismounting the preassembled blind package can be pressed on to the side in order to snap the channel housing 53 into the catch hooks 417, 419 of the support elements 415 or out of the catch hooks 417 , 419 to disengage the support elements 415 or to transfer them from one catch hook 417, 419 to the other.

Insertion guides 433 are expediently designed as sliding surfaces on the lower side regions of the grip tabs 431.

When assembling the blind package, the channel housing 53 equipped with a blind is first pushed into the lower catch hooks 419 of the support element 415 or possibly on one side into the upper catch hooks 417 and on the other side into the lower catch hooks 419 of the support element 415, and then hooked completely into the upper catch hooks 417 by manual pressure from below against the channel housing 53 to become. If the duct housing 53 is hooked into the upper catch hook 417, the pressure knobs 429 of the supporting element 415 secure the duct housing 53 against lateral displacement from the point of view of the fitter, ie against a displacement of the duct housing 53 with respect to the suspension device 411 in the longitudinal direction of the duct housing 52. By the restoring force The downwardly bent upper duct housing ceiling surface 57 of the duct housing 53 is pressed against the knobs 429. The mounting and position securing of the channel housing 53 in the suspension device 411 is essentially ensured by appropriate shaping of the support elements 415 and by the existing channel shape. Restoring forces, which arise when installing the channel housing 53 due to the shape of the support elements 415 between the support element 415 and the suspension device 411, prevent the channel housing 53 from disengaging.

APPLICATION EXAMPLE 3

This in Fig. 18 The multi-part plug-in suspension device concept shown, in contrast to the flat mounting webs 313, 413 of the first or second application example (demonstrates 11 to 14 respectively. Fig. 15 ) additionally has a side bracket 563 extending from an area which is designed as a mounting web 513, which leads from the mounting web 513 to a slide rail acceptance 565. Here, the assembly web 513 is preferably designed as a multiple assembly web. Mounting web 513, side bracket 563 and slide rail assumption 565 together form the fixed mounting bracket 561, as in Fig. 16 is shown. Mounting web 513, bracket 536 and slide rail assumption 565 are advantageously integral areas of the fixed mounting bracket 561. That is, the fixed mounting bracket 561 is made in one piece, at least to the extent mentioned. For example, a fixed mounting bracket such as 561 can be made as a cast part. The bracket part 563 which adjoins the mounting web part 513 and which is bent out to the side (so to speak, laterally) leads in a lateral arc from the mounting web part 513 to the slide rail receiving part 565. In this case, the bracket 563 leads in an arc, ie from an extension 571 (or transverse extension) of the mounting web 513 in a side bend (in particular a one-sided, ie a left-hand or right-hand, bend) around a longitudinal extension of the channel housing receiving areas 535 for slide rail receptacle 565 - in such a way that the slide rail receptacle 565 starts perpendicular to a plane which is spaced parallel to the plane of the surface alignment of the mounting web 513. While the assembly web 513 delimits the channel housing receptacle 535 from above, the slide rail receptacle 565 starts below, expediently essentially in the middle below the longitudinal extension of the channel housing receiving area. The bow or bow 563 (also called bow) is shaped such that it forms a recess for a channel housing 53. The slide rail receptacle 565 is preferably equipped with at least one bore 569 for anchoring.

The use of a fixed mounting bracket 561 enables blinds and slide rails for the blinds to be installed particularly quickly. For the purpose of installing a blind, for example, sliding rails for the blind are first mounted on the side of a window pit. The blind package can be inserted into the slide rails at the same time or pulled into the slide rails after the slide rails have been fastened. The fixed mounting brackets 561 are attached or attached to the mounted slide rails by means of slide rail receptacle 565 after the slide rails have been fastened. A fixed mounting bracket 561 placed on the slide rail can be locked or fastened to the slide rail via the mounting hole 569 by means of anchoring means (in particular by means of a screw). Optionally, the slide rail and fixed mounting bracket can be fixed (or screwed) to the wall of the window pit simultaneously using anchoring means and mounting hole 569. When mounting the fixed mounting bracket 561, the position of the fixed mounting bracket 561 is determined by the previously installed slide rails. This makes assembling a store quick and easy.

Fixing the fixed mounting bracket 561 by means of mounting holes 537 in the area of the mounting web 513 is not absolutely necessary, but can optionally be carried out additionally, for example in the case of blinds which are likely to be particularly heavily used. If the assembly web area 513 is fixed in a window pit at the top and, in addition, the slide rail receiving area 565 is fixed laterally in the window opening, then the entire fixed mounting bracket 561 can be fixed on two mutually perpendicular surfaces on the structure, as a result of which the fixed mounting bracket is fixed in a particularly stable manner.

A fixed mounting bracket 661 shaped essentially in mirror image is shown in FIG Fig. 17 shown. Here, too, the mounting web 613, the side bracket 663 and the slide rail assumption 665 together form the fixed mounting bracket 561. The curved bracket area 663 is similar in design Fig. 17 in contrast to the execution after Fig. 16 however bent out to the opposite side (in Fig. 16 bracket 563 is bent out to the left; in Fig. 16 bracket 663 is bent out to the right). Conveniently, two mirror-image fixed mounting brackets, eg 561 and 661, are used for the installation of each window, preferably one on the left and the other on the right in the window pit.

While two specific exemplary embodiments have been described above, it is obvious that different combinations of the features shown above can be used insofar as the features shown are not mutually exclusive.

While the invention has been described above with reference to specific embodiments, it is apparent that changes, modifications, variations and combinations can be made without departing from the spirit of the invention.
