Description

TECHNICAL AREA

The present invention relates to a channel carrier according to the preamble of claim 1 for attachment of Storenbauteilen on a substrate.

STATE OF THE ART

The assembly of Storenbauteilen is complex and should be safe and reliable, yet as quick and easy to keep costs low. For mounting of Storenbauteilen to carriers for covering building openings therefore channel carrier have been developed, which facilitate assembly of the Storenbauteile.

From the EP 1 617 037 Al a channel carrier has become known, which serves for fixing Storenbauteilen to a support and comprises a U-shaped headband, with a specific for securing the retaining bracket to the support strap web, from which two elastically deflectable arms hang with retaining hooks intended , To encompass end edges of the Storenbauteils. Here, the retaining hooks are formed in the hanger arms. At the hoop web or at most on Storenbauteil an additional spring element is arranged, which acts between Storenbauteil and hoop web such that the end edges of the Storenbauteils are pressed into said retaining hooks.

A disadvantage of this device, however, is that the channel carrier and the spring element in several steps to assemble so that the handling are not optimal.

PRESENTATION OF THE INVENTION

It is therefore an object of the present invention to provide a channel carrier of the type mentioned, which further facilitates the assembly of Storenbauteilen.

• einen Trägersteg zum Kontaktieren des Untergrunds,
• zwei vom Trägersteg abragende und elastisch auslenkbare Trägerarme, welche mit dem Trägersteg eine U-Form bilden, so dass zwischen den Trägerarmen ein Kanal zur Aufnahme für das Storenbauteil gebildet ist, wobei die Trägerarme mit eingeformten Haltehaken zur formschlüssigen Untergreifung des Strorenbauteils versehen sind, und
• ein Federelement zur Sicherung des in den Kanalträger eingesetzten Storenbauteils, dadurch gelöst, dass

der Kanalträger einstückig geformt ist und die Haltehaken das genannte Federelement bereitstellen.These and other objects are achieved by a channel support for securing a blind component to a substrate comprising:

• a carrier web for contacting the substrate,
• two projecting from the support web and elastically deflectable support arms, which form a U-shape with the support web, so that between the support arms a channel for receiving the Storenbauteil is formed, wherein the support arms are provided with molded retaining hooks for positive engagement under the Strorenbauteils, and
• a spring element for securing the stator component used in the channel carrier, achieved in that

the channel carrier is integrally formed and the retaining hooks provide said spring element.

The substrate on which the channel carrier is to be mounted, in this case is in particular a door or window frame or a section of a ceiling or wall.

The retaining hooks are bent or shaped as hook elements into the carrier arm such that a portion of the carrier arm is at an angle to the direction of a longitudinal extension of the carrier arm against a channel formed between the carrier arms and the carrier web, such that the stator component is in the end position in the direction of the longitudinal extension of the carrier arm is resiliently blocked by the hook elements in particular against a possible gravity effect.

It is an aspect of the present invention to further develop a generic channel carrier in such a way that facilitates its assembly, reduces the cost of materials and thus the prices for the end customer can be lowered.

The support arms are preferably substantially perpendicular to the same side of the preferably substantially planar support web and form the U-shaped Channel carrier with the aforementioned channel for receiving the Storenbauteils.

It is preferred that a free end portion of the support arm along a first bending line bend a distal first hook portion inwardly of the channel, such that a first inner bending angle about the first bend line between a proximal support arm portion and the first hook portion is at an acute angle, preferably in the range of 40 to 80 degrees, in particular of substantially 60 degrees.

The directional definition "inward" here is to be understood such that the first hooking section to be bent is bent around the first bending line against the channel formed by the channel support between its support arms, ie in cross-section against a center of area of the channel. Depending on the viewing angle, the bending direction thus defined is a clockwise or counterclockwise bend about the first bending line. For bending operations on the same support arm around further bending lines, assuming the same viewing angle, the same directional definition is used, unless otherwise stated or understood from the context. Thus, if, for example, the first hook portion is bent inwardly and thus clockwise with respect to a fixed viewing angle about the first bend line, then bending another hook portion of the same support arm about another bendline inwardly also means bending that further hook portion clockwise about corresponding bending line, wherein "outwards" each denotes a bend in the opposite sense of a bend "inwards".

In a preferred embodiment, the distal end portion of the support arm ("distal" and "proximal" are to be understood with respect to the carrier web) between a proximal Trägerarmabschnitt and the first bending line on a second bending line, wherein a second hook portion between the second and the first bending line extends and is bent outwards, such that between the proximal support portion and the second hook portion, a first outer bending angle about the second bending line an obtuse angle, preferably in the range of 100 to 170 degrees, more preferably from 140 to 165 degrees and in particular about 153.5 degrees or about 159 degrees. In a cross-sectional view on the U-shape of the carrier is by this bend around the second Bend line the first bend line offset to the outside. In a preferred straight proximal support arm portion, then the first bend line is outside (with respect to the channel) a plane through the proximal support arm portion. Preferably, the second bending line is curved rounded and not sharp or bent at an angle. This round bending line or bending edge makes the second bending line act as a fulcrum and reduces local fatigue in repeated resilient deflection, whereby the second hook portion and the distal thereto first hook portion with respect to the proximal Trägarmabschnitts is elastically deflectable about the second bending line.

Furthermore, it is preferable that a free end portion of the first hook portion is bent inwardly along a third bending line to form a free fourth hook portion. Between the first and the third bending line extends a third hook portion. Between the third and the fourth hook portion, a second outer bending angle about the third bending line is preferably less than 10 degrees, preferably less than 5 degrees.

A section of the fourth hook section arranged proximally to the third bending line in this case runs as a fifth hook section, preferably parallel along the third hook section and preferably immediately adjacent thereto, wherein preferably a free end section of the fourth hook section is bent along a fourth bend line forming a free sixth hook section such that the sixth hook portion is preferably parallel and preferably immediately adjacent along the proximal support arm portion. Thus, the sixth hook portion adjoins the fifth hook portion, both together forming the fourth hook portion. By this additional bend around the third and fourth bend line a kind of loop is bent into the distal end of the support arm. Preferably, the third bending line is sharp and the fourth bending line in turn bent around like the second bending line. Thus, the fourth bending line also acts as a fulcrum as described above. The sixth hook portion preferably protrudes beyond the second bending line against the support web and covers a distal end of the proximal support portion extending in parallel over 5 to 20 millimeters to the channel.

By this design, a channel carrier is specified with holding hook, which is easier to accommodate Storenbauteile of different heights in the direction of the proximal support arm. The respective hook element may be formed by bending back the fifth hook element, i. be changed by increasing the second outer bending angle so that even Storenbauteile with smaller height are securely secured under positive engagement in the channel.

It is preferred that a length of the proximal support section is in the range of 45 to 65 millimeters, in particular substantially 55 millimeters, and / or
a length of the second hook portion is in the range of 4 to 8 millimeters, in particular substantially 6 millimeters, and / or
a length of the third hook portion is in the range of 8 to 12 millimeters, in particular substantially 10 millimeters, and / or
a length of the fifth hook portion is in the range of 4 to 7.5 millimeters, in particular substantially 5.7 millimeters, and / or
a length of the seventh hook portion is in the range of 8 to 12 millimeters, in particular substantially 10 millimeters, and / or
a width of the carrier web is in the range of 10 to 40 millimeters, in particular substantially 25 millimeters.

In a further refinement, the preferably substantially planar carrier web has at least one, preferably two or more stops projecting perpendicularly into the channel for the stator component, wherein the stops preferably have a projection height in the range of 3 to 7 millimeters, in particular of substantially 4.8 or 5 Millimeters. A length of the flat carrier web is preferably in the range of 55 to 70 millimeters, in particular of 60 to 65 millimeters and particularly preferably of substantially 62 millimeters.

Particularly preferred are stops, which consist of bent towards the channel carrier web material. For this purpose, for example, a tab from a central region of the web can be cut free such that the tab is only along a bending line with the carrier web material in connection and bendable around this bending line in the channel, that the tab as a stop substantially perpendicularly from the carrier web protrudes and at the same time a recess is formed in the web. Alternatively, the tab can also be connected between the support arms on the edge side with the carrier web, so that this tab protrudes laterally over the carrier web like a wing and can be bent upwards towards the channel in order to form a stop.

In an alternative embodiment, the stops are provided by the support arms, wherein in each support arm in each case at least one centrally with respect to the width of the respective arm lying, cut-free tab, which communicates only to one side with the support arm and bend transversely into the channel is to form a stop for the Storenbauteil. This bending line can in this case also be offset towards the distal end of the tab, such that the tab runs parallel to the carrier arm in a first section adjoining the carrier arm up to said bending line and with a second section which adjoins the first bent to the channel. It is preferable to provide a recess of about one millimeter around the tab. Further, it is preferred if the tab extends in width about 20 to 75% of the width of the support arm. Alternatively, these tabs may also wing-like, as described above for the support web, but be mounted on the edge side of the support arm, it is then preferred that two such wing-like tabs lie directly across the width of a support arm.

Instead of the bent tabs and correspondingly shaped beads in the carrier web or in the support arm are conceivable. In any case, it is advantageous if the stops for the stator component are formed from the channel carrier material, so that a one-piece channel carrier is provided.

The stops, as described above, serve as a stop for the Storenbauteil inserted into the channel, and thus are designed such that the Storenbauteil inserted into the channel rests on its one side in these attacks and lies on its opposite side in the resilient hook, which press the Storenbauteil in the stops and also allow by their spring property to fix Storenbauteile different heights in the channel carrier.

The stops are preferably about 3 to 25 millimeters from the carrier web and allow, on the one hand, easily by appropriate bending of the stops to provide channel support for different high Storenbauteile and on the other to accommodate a fastener in the space between the stop and the carrier web, for example screw head.

Advantageously, a recess in the carrier web for carrying out this fastening means, in particular in the form of a screw, is provided. The screw head is in this case surmounted on several sides of said attacks, so that used Storenbauteile rest on the attacks and not on the screw head.

In a particularly preferred embodiment, a free end portion of the aforesaid sixth hook portion is bent along a fifth bending line forming a distal eighth hook portion forming from the proximal arm portion, such that the eighth hook portion serves as an end stop for the used Storenbauteil. This end stop acts as the attacks described above, as a support for the used Storenbauteil. In this embodiment replace the short and preferably by sharp bending by substantially about 90 degrees or more, for example. By 100 to 114 degrees, received against the middle of the channel end stops so the aforementioned stops in the carrier web.

It is preferred that a length of the seventh hook portion is in the range of 45 to 65 millimeters, in particular substantially 53 millimeters and / or a length of the eighth hook portion is in the range of 2 to 15 millimeters, in particular in the range of 3 to 6 millimeters , in particular substantially 5 millimeters.

With regard to a type of bending of the support arm about the respective bending lines, it is preferred that the foremost, ie first, first bending line in the direction from the proximal end of the support arm (ie the first or if there is a second bend line, this second bend line) to its distal end and possibly the fourth bending line are each bent around. A radius of curvature of an outer curve of the round bent bending line is preferably in the range of 1 to 5 millimeters, in particular in the range the simple to double material thickness of the bent sheet, preferably at best further bending lines are bent at an angle.

In a preferred embodiment, in each case a recess in the support arm in the region of the round bent bending line (s) is introduced, such that a cross section of the support arm along said round bent bending line (s) reduced and preferably to less than half, in particular substantially is reduced to one third of a total width of the support arm. The recesses therefore preferably remove parts of the round bending lines.

Preferably, all said bending line (s) extend transversely to a longitudinal extent of the support arm.

The support arms preferably each protrude at an inner abutment angle in a range of 80 to 95 degrees, more preferably in a range of 85 degrees to 90 degrees, and most preferably substantially less than 89 degrees, with an inner edge, i. the bending edge between the carrier web and the carrier arm, channel side sharply bent.

A width of the support arm in the direction of the free end of the support arm preferably tapers, in particular increasingly from the first bend line and preferably symmetrically, wherein a final width is about half as large as a maximum width or even smaller.

In addition, it is an object of the present invention to provide a sheet metal strip which is bendable by bending in a channel carrier according to the invention.

These and other objects are achieved by a metal strip with recesses in that the sheet metal strip is formed by bending to an aforementioned channel carrier, the sheet metal strip having a central portion with a constant width and preferably symmetrically in the width tapering free and equal length end portions, wherein a Ratio of a length of the central portion to a length of the end portion is substantially about 2.5.

Preferably, some of the recesses are arranged in the transition region from the aforementioned central portion to the end portions, wherein the recesses take out about half or more of the cross-section or the width.

A total length of the metal strip is preferably between 20 and 35 centimeters. The thickness of the metal strip may in particular be between 0.5 and 3 millimeters.

As the material for the channel carrier described herein steel, especially spring steel in sheet form is preferred. In particular, a carbon-containing steel is suitable. Preferably, this steel is curable. Basically, therefore, tempered steel is preferred, wherein the steel sheet formed therefrom is preferably 0.5 to 1.5 millimeters, in particular about 1 millimeter thick. The steel sheet is also preferably galvanized or galvanized after curing.

The channel carrier described herein is used, for example, advantageously for the assembly of components, in particular of Storenbauteilen on a substrate. The lengths specified herein are readily adaptable by a skilled person to the Storenbauteil to be fixed.

DESCRIPTION OF PREFERRED EMBODIMENTS

FIG. 1 schematically shows a first embodiment of a channel carrier 1 in a side view. The channel carrier 1 consists of a planar carrier web 2, on which a first straight carrier arm 3a and, opposite, a second straight carrier arm 3b (see FIG. Fig. 7 ) connect. Between the support arms 3a, 3b and the carrier web 2, a channel 10 for receiving a Storenbauteils is formed. The support arms 3a and 3b are obtained by bending a sheet metal strip, wherein the sheet is bent along a corresponding bending line to the channel 10. The support arms 3a, 3b are elastically deflectable to the side and protrude in undeflected state in the end position in a Abragungswinkel δ of about 90 degrees, preferably from about 87 to 89 degrees from the carrier web 2 from. It is therefore preferred that the channel 10 widened towards the carrier web 2 to something.

The carrier arm 3a extends from its proximal end to its distal end via a carrier arm portion 31 away from the carrier web 2. Distal on the support arm 3a, a first retaining hook 4a is formed in the support arm 3a. For this purpose, the distal end portion of the arm 3a is bent to form a first hook portion 41 around a first bending line B ₁ . The first hook portion 41 forms with the support portion 31 at an acute angle, the first inner bending angle α, which is preferably about 40 to 80 degrees, in particular about 60 to 66 degrees. The first hook portion 41 in this case acts resiliently blocking on a force parallel to the Trägerarmabschnitt 31st

FIG. 2 shows a development of the holding hook 4a after Fig. 1 , In Fig. 2 is in the Trägerarmabschnitt 31, ie between the first bending line B ₁ and the carrier web 2, a second bending line B _{2 is} provided. The sheet is bent a second hook portion 42 around the second bending line B ₂ , the first bending line B ₁ is preferably sharp or angled. The second hook section 42 lies between the first and the second bending line B ₁ , B ₂ . The support arm 3a is bent outward with respect to the channel around the second bending line B ₂ such that the first bending line B ₁ lies outside a plane through the support arm section 31. A first outer bending angle β formed thereby is an obtuse angle and is about 140 to 170 degrees, in particular about 150 to 155 or 153.5 degrees. According to this development Fig. 2 the suspension of the first hook portion 41 is further improved.

FIG. 3 shows a further development of the holding hook 4a after FIG. 2 , In Fig. 3 The first hook portion 41 has a third bending line B ₃ around which the first hook portion 41 is bent to form a third hook portion 43 and a fourth hook portion 44. The third hook portion 43 extends between the first bending line B ₁ and the third bending line B ₃ , wherein the fourth hook portion 44 adjoins the third hook portion 43. Between the third hook portion 43 and the fourth hook portion 44, a second outer bending angle γ is formed, which is an acute angle of about 5 to 30 degrees. The bend around the third bend line B ₃ is preferably a sharp bend. In this case, the third hook section 43 is bendable so as to bend the second outward bending angle γ around the third bending line B _{3 in} such a way that a height between the carrier web 2 and the fourth hook section 44, that is to say a height of the channel 10, can be set. The training according Fig. 3 Thus, allows a height of the channel 10 easy to adjust and optimizes the spring action of the holding hook 4a by the additional resilient fourth hook portion 44 on.

FIG. 4 shows a development of the holding hook 4a after FIG. 3 , In FIG. 4 the fourth hook section 44 has a further fourth bending line B ₄ . The fourth hook portion 44 is bent around the fourth bending line B ₄ , thereby forming a fifth hook portion 45 and a sixth hook portion 46 having a free end portion. Here, the bend around the fourth bending line B _{4 is} preferably round and such that the sixth hook portion 46 is substantially parallel to the support portion 31 and immediately complains runs to it. By continuing according to Fig. 4 the adjustment of the height of the channel 10 of the channel carrier 1 is further simplified adjustable. In addition, an inserted component contacts the sixth hook portion 46 and presses it laterally against the support portion 31, which causes a further stabilization of the used Storenbauteils in channel 10.

FIG. 5 shows a further development of the holding hook 4a after Fig. 4 , In Fig. 5 6, the sixth hook section 46 has a further bending line which divides the sixth hook section into a seventh hook section 47 and an eighth hook section 48. The sixth hook portion 46 extends as in the embodiment according to Fig. 4 Preferably, the seventh hook portion 47 extends substantially perpendicular to the carrier web 2. Since the corresponding carrier arm 3a preferably protrudes at about 89 degrees from the carrier web 2, the seventh hook portion 47 preferably extends at an angle of about 1 to 2 degrees to the support portion 31 so that the seventh hook portion 47 is increasing in the direction of the support web 2 away from the support portion 31 and substantially perpendicular to the web 2 tapers. The free end portion of the hook portion 46 is bent here as an eighth hook portion 48 against the channel 10 and forms a stop for the inserted into the channel 10 Storenbauteil. The eighth hook portion 48 is substantially perpendicular from the seventh hook portion 47 and the support portion 31 in the channel 10 into it. This development of the holding hook 4a according Fig. 5 allows a stop for the blind component to be provided without the material having additional cutting or punching locations. A support arm 3a according to Fig. 5 with a retaining hook 4a is thus easy to produce by bending steps.

FIG. 6 shows a cross section of a preferred embodiment according to Fig. 5 , wherein the representation according to Fig. 6 additionally represents preferred length ratios and angles between the individual hook portions 41 to 48 and the support portion 31 and thereby from the schematic representation according to FIG Fig. 5 different.

In the following, four preferred embodiments of the channel carrier 1 will be described with reference to FIG FIGS. 7 to 29 described.

A first preferred embodiment of the channel carrier 100 is in the FIGS. 7 to 12 shown. This shows FIG. 7 a cross section through the first embodiment. It can be seen, the carrier web 2 with the substantially laterally of the web 2 perpendicular from the web 2 projecting support arms 3a and 3b, between which the channel 10 is formed. In the end portions of the support arms 3a and 3b retaining hooks 104a and 104b are formed, which substantially the hook member 4a of Fig. 4 correspond.

It is preferred that the support arms 3a and 3b each protrude from the support web 2 at an angle of about 89 degrees (as mentioned above). Furthermore, the carrier web 2, a central, rectangular recess 123 can be seen, wherein a portion of the recessed by recess 123 material as stops 21 and 22 is bent against the channel 10. The stops 21 and 22 protrude by about 4.8 millimeters into the channel 10 and are perpendicular from the carrier web 2 from. In addition, in the carrier web 2 two outwardly projecting, parallel to and extending in the carrier web 2 beads 25 can be seen. These beads 25 allow in contact with the ground on which the channel support 100 is to be fastened, an optimal fastening under prestress by a fastening means such as a screw. The beads 25 protrude outwards by about 1 to 3 millimeters and are of semicircular cross-sectional shape. The beads 25 extend continuously on both sides of the recess 123 and extend substantially over the length of the web second

The channel 10 according Fig. 7 can now, for example, by a screw which engages through the recess 123 with its bolt, are attached to a substrate, the screw head between the stops 21 and 22 recessed in the channel 10 remains and laterally clamped on the web 2 this resting against the ground. Thus, then inserted into the channel carrier 100 Storenbauteil is on the stops 21 and 22.

FIG. 8 shows a side view of the channel carrier 100 according to Fig. 7 in a plan view of the first support arm 3a. In particular, in Fig. 8 Recesses 33 and 34 can be seen, which are introduced in the support arms 3a and 3b in the region of the retaining hooks 104a, 104b. The recesses 33 and 34 are circular in shape and reduce the material cross section at their position, which causes the spring action of the hook member 104a, 104b is improved. In particular, the recesses 33, 34 cause a spring constant of the hook elements 104a, 104b to be reduced because they are parts of the bending lines B ₂ and B ₄ , which means that the hook elements 104a, 104b feathers more easily.

FIG. 9 shows a bead-side plan view of the support web 2 and can see the course of the beads 25 on the support web 2. In addition, the central position and the approximate extent of the recess 123 in the carrier web 2 can be seen.

FIGS. 10 and 11 show the channel carrier 100 according to FIGS. 7 to 9 with a Storenbauteil. In Fig. 10 the first support arm 3a is slightly elastically deflected to the side due to the Storenbauteils. If pressure is now exerted on the carrier arm 3a against the channel 10, the hook element 4 springs over one end of the stator component and engages under a bias to secure the stator component, as in FIG Fig. 11 shown.
