Description

[0001] The present invention relates to a pull / push support bar made of plastic, a guide rail, in particular a roller blind guide rail, comprising such a pull / push support bar, and a roller blind arrangement comprising such a guide rail.

[0002] Plastic tension / compression support strips are available in various designs and for different areas.

[0003] For example, DE 10 2007 048 548 A1 discloses a roof connection profile that can be installed after the roof structure has been completed and allows for compensation of relative movements between the roof and the wall or insulation. This roof connection profile comprises a plaster strip with at least one web angled at an angle corresponding to the roof pitch and a roof fastening strip connected to it by a bellows.

[0004] In many other areas, plastic skirting boards are also subject to relative movement, often caused by temperature and humidity fluctuations. This is often due to the fact that two different materials are joined with a plastic profile, as is the case with skirting boards, for example, which usually connect a wooden, tile, or plastic floor to a plasterboard or brick wall.

[0005] Another example is the slats / profiles of external sun protection systems, such as roller blinds or venetian blinds, which can be exposed to wind forces. A moderate wind speed is usually sufficient to subject the blind or venetian blind to relative movement / loading forces, causing it to bend or causing parts of the blind to swing back and forth between the guide rails, resulting in annoying rattling noises.

[0006] With fabric blinds, the fabric can be stretched between two profiles, allowing it to move up and down along guide rails. When the blind is closed, the fabric can be exposed to gusts of air. Therefore, it is desirable for the profiles to absorb these gusts. Foam pads are known to be glued to the profiles to absorb these gusts.

[0007] It is therefore an object of the present invention to provide a tension / compression support bar and a guide rail with such a tension / compression support bar, which can compensate for relative movements and thus minimize occurring loading forces and stresses.

[0008] This problem is solved by the subject matter of independent claim 1. Advantageous further developments emerge from the dependent claims.

[0009] The plastic pull / push receiving strip according to the invention has a first functional side; a second functional side; and at least one spring leg which resiliently connects the first functional side and the second functional side to one another in the direction of the change in distance between the first and second functional sides, wherein the at least one spring leg has at least one slot or recess which extends transversely or perpendicularly to the direction of the change in distance between the first functional side and the second functional side, for reducing the pull / push force of the at least one spring leg.

[0010] In the area of the at least one slot or the at least one recess, the at least one spring leg no longer has any resistance. This allows the overall resistance of the spring leg to be reduced when the tension / compression support bar is loaded.

[0011] When the spring leg is subjected to a load of any kind, in particular tensile, compressive, buckling, bending or torsional load, the resulting forces are reduced by the at least one slot or the at least one recess, compared to a spring leg that is of solid construction.

[0012] This allows the resistance of the spring leg to be reduced and individually adapted to the respective application situation without having to change the material thickness of the spring leg overall.

[0013] The slot(s) may extend through the entire wall thickness of the spring leg.

[0014] In particular, the recess(es) extend(s) only to a middle position of the wall thickness of the spring leg and do(es) not extend through the entire wall thickness of the spring leg.

[0015] If the at least one spring leg is formed with at least one recess, a seal can be achieved between both sides of the spring leg.

[0016] A plastic tension / compression support strip according to the invention can be used wherever a strip is required to absorb movements and thereby exert a damping or spring effect, and in particular to absorb, dampen, or cushion occurring forces or stresses. Such a strip can be installed in any position, for example, horizontally or vertically.

[0017] In addition to the application described below in a roller blind guide rail or a roller blind arrangement, the pull / push support strip made of plastic according to the invention is also particularly suitable for applications such as plastering profiles / plastering strips, skirting boards, corner angles, building profiles / building strips, refrigerators, dishwashers and the like.

[0018] In a first embodiment, the tension / compression receiving strip has two spring legs which resiliently connect the first functional side and the second functional side to one another in the direction of the change in distance between the first and second functional sides, wherein the first and the second spring leg have at least one slot or a recess which extends transversely or perpendicularly to the direction of the change in distance between the first functional side and the second functional side, in order to reduce the tension / compression force of the first and the second spring leg.

[0019] Preferably, the first functional side and the second functional side are arranged substantially parallel to one another and the first functional side is designed to be arranged at a distance from a first counter surface and the second functional side is designed to bear against a second counter surface.

[0020] When used in a roller blind guide rail or a roller blind assembly, the first functional side and the second functional side are each designed as surfaces, in particular a flat end surface or a flat contact surface. The first functional side and the second functional side can be individually designed depending on the application, for example, with an adhesive strip or a plastering area.

[0021] According to one embodiment, the first functional side and the second functional side are movable between a first position of minimum height (F1), in which the at least one spring leg is strongly compressed and in particular adjacent partial regions of the spring leg abut one another, and a second position of maximum height (F0), in which the at least one spring leg is strongly pulled apart.

[0022] The second position of maximum height (F0) can be in the non-force-loaded state or when the strip is being installed. In this position, no forces, which could arise from relative movements, for example, act on the strip. If a load acts on the strip, such as a compressive or tensile load, at least one spring leg is strongly compressed and the first functional side and the second functional side are in the first position of minimum height (F1). In this state, the slots or recesses arranged in the spring leg(s) widen and the forces resulting from the load can be minimized.

[0023] Of course, a spring leg or the spring legs can also assume intermediate positions between the position of maximum height (F0) and the position of minimum height (F1).

[0024] The plastic tension / compression support strip according to the invention thus withstands flexible changes in tension, compression, bending, buckling and torsional forces.

[0025] In a further embodiment, the at least one spring leg has a zigzag cross-section, a bent cross-section, a curved cross-section, or a multiply corrugated cross-section. In particular, in the case of a curved cross-section or a multiply corrugated cross-section, the curvature or the corrugations extend outwardly or inwardly, respectively.

[0026] If a spring leg has such a cross-section, the spring leg or legs can be compressed more easily, i.e. with less resistance, under load.

[0027] The at least one spring leg can be attached to the rear sides of the first and second functional sides and can be formed integrally therewith.

[0028] The plastic tension / compression support strip can be an extruded plastic profile or can be manufactured by extrusion. The at least one slot / at least one recess is created by cutting or punching into the (respective) spring leg.

[0029] In a further embodiment, the first functional side forms a continuous end surface. Additionally or alternatively, the second functional side can be designed in the form of two spaced-apart contact surfaces, so that a receiving space, in particular for an edge of a roller blind, is formed between the first and second contact surfaces and the first and second spring legs. A receiving device, in particular a holder for the edge of a roller blind, can be formed on the rear side of the first functional side.

[0030] In a further embodiment, the at least one slot or the at least one recess has a straight profile that runs essentially in the longitudinal direction of the strip. Alternatively, the at least one slot or the at least one recess can have a wavy or zigzag profile. Preferably, the at least one spring leg has a plurality of slots or a plurality of recesses.

[0031] In a further embodiment, the slots or recesses are arranged at two or more height positions of the at least one spring leg.

[0032] In a preferred embodiment, the slots or recesses are arranged at corresponding height positions of the first and second spring legs. This ensures that the total resistance of both spring legs is equal, and relative movements can be better compensated.

[0033] In a further embodiment, several slots / recesses are arranged one after the other at a height position of the at least one spring leg, viewed in the longitudinal direction of the strip, with regions of the spring leg without slots / recesses being arranged between two adjacent slots / recesses. Preferably, the at least one spring leg each has a zigzag cross-section, and the slots / recesses are arranged at the bending regions, in particular at the outer bending regions of the at least one spring leg.

[0034] The resistance of the spring leg can be controlled by the arrangement, length and shape of the slots.

[0035] The at least one spring leg can each have a curved cross-section, and the slots / recesses can be arranged at at least one height position of the curvature. The slots / recesses are preferably located in the region of the apex of the curvature. Alternatively, the at least one spring leg can have a multiply corrugated cross-section, and the slots / recesses can be arranged at at least one height position of a wave and / or in a transition region between two adjacent waves. The slots / recesses are preferably located in the region of the apex of the curvature and in the transition region between two adjacent waves.

[0036] The pull / push support strip described above can be used as a plaster profile, skirting board, corner bracket, or construction profile. Furthermore, this pull / push support strip can also be used in appliances such as refrigerators or dishwashers.

[0037] The tension / compression support bar described above can have a U-shaped, L-shaped, or T-shaped profile. The tension / compression support bar can have a bellows profile, in which the spring legs are extruded with the profile and then slots and / or recesses are introduced into the spring legs. This can reduce the overall resistance when the bar is loaded.

[0038] The guide rail according to the invention, in particular a roller blind guide rail, comprises a substantially rectangular cross-section, a guide slot for guiding a lateral edge of a roller blind, an inner receiving space with an inner bottom surface, two inner flank surfaces and two inner end surfaces, adjacent to the guide slot, wherein a pull / push receiving strip according to the invention with a first and a second spring leg, as described in the embodiments above, is inserted into the inner receiving space of the guide rail such that its first functional side points towards the inner bottom surface and is arranged in particular at a distance therefrom such that the two spaced-apart contact surfaces of the second functional side point towards the inner end surfaces of the guide rail or rest against them, and such that the lateral edge of the roller blind in the receiving device,in particular the bracket is mounted on the back of the first functional side.

[0039] With fabric roller blinds, the fabric can be stretched between two profiles to allow it to move up and down along guide rails. When the blind is closed, the fabric can be exposed to gusts of air. The innovative push / pull support bar on the guide rail can compensate for these gusts.

[0040] In one embodiment, by means of the first and second spring legs and the at least one slot or the at least one recess of the first and second spring legs, the receiving device on the rear side of the first functional side and the lateral edge of the roller blind can be resiliently movable between an outer position in which the first functional side of the pull / push receiving strip rests against the inner bottom surface of the inner receiving space of the guide rail and an inner position in which the first and second spring legs are pressed together and the first functional side of the pull / push receiving strip is arranged away from the inner bottom surface of the inner receiving space of the guide rail.

[0041] In a further embodiment, the first and the second spring leg can each have a zigzag cross-section and in the inner position of the receiving device, the first and the second functional side of the first and the second spring leg can each be compressed to such an extent on the back of the first functional side and the lateral edge of the roller blind that adjacent straight sections of the first and the second spring leg abut one another.

[0042] The designs and advantages described for the pull / push mounting bar also apply to the guide rail with a pull / push mounting bar.

[0043] The invention also relates to a roller blind arrangement comprising a roller / shaft with a roller blind that can be unrolled therefrom and rolled up thereon, which is in particular surrounded by a cassette, two lateral guide rails, as described above, wherein the lateral edges of the roller blind are received in the receiving devices on the rear side of the first functional side of the respective pull / push receiving bar in the two guide rails.

[0044] The designs and advantages described for the pull / push support bar and for the guide rail also apply to the roller blind arrangement with two such guide rails.

[0045] The invention is explained in more detail below using an embodiment with reference to the accompanying figures.

Fig. 5 shows a perspective view diagonally from the front of a spring leg of the pull / push receiving bar from one of the Figures 1 to 4in an extended state and in a compressed state, wherein the spring legs have a zigzag cross-section. Fig. 6 shows a perspective view obliquely from the front of two spring legs which have a curved cross-section, according to a further embodiment of the invention. Fig. 7 shows a perspective view obliquely from the front of two spring legs which have a multiply curved cross-section, according to a further embodiment of the invention. Fig. 8 shows a perspective view diagonally from the front of a roller blind arrangement.

[0046] The Figure 1The plastic tension / compression support strip 2 shown has a first functional side 4, a second functional side 6, and two spring legs 8. The two spring legs 8 resiliently connect the first functional side 4 and the second functional side 6 in the direction of the change in distance between the first 4 and the second functional side 6. The first and second spring legs 8 have a zigzag cross-section.

[0047] The first and second spring legs 8 can be arranged as shown in Figure 5 shown, with slots 10 extending perpendicular to the direction of the change in distance between the first functional side 4 and the second functional side 6. The slots 10 reduce the tensile / compressive force of the first and second spring legs 8.

[0048] The first functional side 4 and the second functional side 6 are arranged essentially parallel to each other. The first functional side 4 is arranged at a distance from the counter surface 12. The second functional side 6 rests against the counter surface 14. In Figure 1 the two spring legs 8 are pulled apart and are in a position of maximum height (F0). From this position, the two spring legs 8 can be moved to a position of minimum height (F1), which is Figure 2 is shown.

[0049] The first and second spring legs 8 are attached to the rear sides 16, 18 of the first functional side 4 and the second functional side 6 and are formed integrally therewith. The first functional side 4 is designed as a continuous end surface, and the second functional side 6 is designed in the form of two spaced-apart contact surfaces. Between the first end surface 4 and the second contact surface 6 and the first and second spring legs 8 there is a receiving space 20 for an edge of a roller blind 22. A holder (receiving device 24) for the edge of a roller blind 22 is arranged on the rear side 16 of the first functional side 4.

[0050] Figure 1also shows a guide rail 26 with a substantially rectangular cross-section, with a guide slot 28 in which the lateral edge of the roller blind 22 can be guided, with an inner receiving space 30 with an inner bottom surface 32, two inner flank surfaces 34 and two inner end surfaces 36, adjacent to the guide slot 28.

[0051] The pull / push receiving strip 2 is inserted into the inner receiving space 30 of the guide rail 26 such that its first functional side 4 is arranged at a distance from the inner bottom surface 32, that the two spaced-apart contact surfaces of the second functional side 6 rest against the inner end surfaces 36 of the guide rail 26, and that the lateral edge of the roller blind 22 is received in the receiving device 24 or in a holder on the rear side 16 of the first functional side 4.

[0052] Figure 2shows the pull / push support bar 2 made of plastic and the guide rail 26 as in Figure 1 , whereby the two spring legs 8 are strongly compressed and adjacent sections of the spring legs 8 are in contact with each other. The spring legs 8 are thus in a first position of minimum height (F1). From this position, the two spring legs 8 can be moved into the second position of maximum height (F0), which is Figure 1 is shown.

[0053] The pull / push receiving strip 2 is inserted into the inner receiving space 30 of the guide rail 26 such that its first functional side 4 points in the direction of the inner bottom surface 32, that the two spaced-apart contact surfaces of the second functional side 6 rest against the inner end surfaces 36 of the guide rail 26, and that the lateral edge of the roller blind 22 is received in the receiving device 24 or a holder on the rear side 16 of the first functional side 4.

[0054] In the top view of the Figures 3 The plastic pull / push support bar 2 can be clearly seen with its first functional side 4, its second functional side 6, and its two spring legs 8 with a zigzag cross-section.

[0055] The first and second spring legs 8 can be arranged as shown in Figure 5 shown, with slots 10 that extend perpendicular to the direction of the change in distance between the first functional side 4 and the second functional side 6. The slots 10 reduce the tensile / compressive force of the first and second spring legs 8.

[0056] In the Figure 3 In the position shown, the two spring legs 8 are pulled apart and are in a position of maximum height (F0). From this position, the two spring legs 8 can be moved to the position of minimum height (F1) (see Fig. 4 ).

[0057] In the Figures 3 and 4It is also clearly visible that the second functional side 6 of the tension / compression support bar 2 rests against the counter surface 14. In Figure 3 the first functional side 4 of the strip is at a short distance from the counter surface 12 and in Figure 4 arranged at a large distance from the counter surface 12.

[0058] In the top view of the Figure 4 the two spring legs 8 are strongly compressed, and adjacent parts of the spring legs 8 lie against each other.

[0059] With reference to Figure 8 one can easily imagine that the roller blind is in a vertical plane and that the pull / push support bars 2 in the two lateral guide rails 26 are each in the Figure 1 and Figure 3 shown position, in which the two spring legs 8 are pulled apart and are in a position of maximum height (F0).

[0060] If a force, such as wind pressure from the front or rear, acts on the roller blind fabric, the side edges and thus the receiving space 24 are pulled inward, with the spring legs 8 exerting a defined springy or damping counterforce. The two spring legs 8 are thus strongly compressed, and adjacent sections of the spring legs 8 rest against each other.

[0061] Figure 5 shows a spring leg 8 of the tension / compression support bar 2 in a first position of maximum height (top) and in a second position of minimum height (bottom). In the first position, the spring leg 8 is strongly extended. In the second position, the spring leg 8 is strongly compressed, and adjacent sections of the spring leg 8 are in contact with one another.

[0062] The spring legs 8 are formed with several slots / recesses 10 that have a straight course. The slots / recesses 10 are arranged at the outer bending areas of the spring leg 8. The Figure 5 The spring legs 8 shown have three outer bending areas, each of the outer bending areas has several successively arranged slots / recesses 10, whereby between two adjacent slots / recesses 10 there are areas of the spring leg 8 without slots / without recess (X). The length of the slots / recesses 10 is in Figure 5 marked with (Y). The slots / recesses 10 of the respective bending areas are arranged flush above or below each other.

[0063] In an alternative embodiment not shown here, the slots / recesses 10 of the respective bending regions can be arranged offset.

[0064] The slots / recesses 10 reduce the tensile / compressive force of the first and second spring legs 8.

[0065] Figure 6 shows sections of two spring legs 8 of a tension / compression support strip, which have a curved cross-section. The spring legs 8 have several straight, consecutively arranged slots / recesses 10, which are located at a particularly central height position of the curvature. The slots / recesses 10 are located in particular in the area of the apex of the curvature. The slots / recesses 10 are located at corresponding height positions of the first spring leg 8, which is Figure 6 shown above and the second spring leg 8, which is in Figure 6 shown below.

[0066] As in Figure 7As can be seen, the two spring legs 8 of a tension / compression support strip can also have a double-curved cross-section. The spring legs 8 also have a plurality of straight, consecutively arranged slots / recesses 10, which are arranged at several, here three, height positions of a wave, in particular in the region of the apex of the upper curvature, in the region of the apex of the lower curvature, and in the transition area between the upper and lower curvature / wave.

[0067] The slots / recesses 10 are at corresponding height positions of the first spring leg 8, which is in Figure 7 shown above and the second spring leg 8, which is in Figure 7 shown below.

[0068] The course of the zigzag profile or the curvatures 10 is mirrored in the first and the second spring leg 8 along a plane which is in the Figures 3 and 4runs horizontally along the plane of the arrows F0 and F1.

[0069] The slots / recesses 10 of the Figure 5-7 The spring legs 8 shown would, when used in the tension / compression receiving strip 2 according to the invention, run essentially in the longitudinal direction of this strip 2.

[0070] One can well imagine that the Figures 6 , 7 and 8 shown spring leg 8 at the location of the spring leg 8 of the tension / compression support bar 2 in the Figures 1-4 In other words, two spring legs 8 of the Figures 6 , 7 and 8 together with the first functional side 4, the second functional side 6 and the receiving space 20 each form a pull / push receiving strip 2 according to the invention.

[0071] Figure 8shows a roller blind arrangement 38 with a roller / shaft (not shown) with a roller blind 22 unrolled therefrom, a cassette 40 surrounding the roller / shaft, and two lateral guide rails 26.

[0072] The lateral edges of the roller blind 22 are received in the receiving devices 24 on the rear side 16 of the first functional side 4 of the respective pull / push receiving bar 2 in the two guide rails 26. Such a roller blind arrangement 38 can compensate for relative movements between the roller blind 22 and the receiving bar 2, which are caused, for example, by a force such as wind pressure or gusts of air from the front or rear acting on the roller blind fabric. If this causes the lateral edges and thus the receiving space 24 of the respective pull / push receiving bar 2 to be pulled inward, the spring legs 8 apply a resilient or damping counterforce.
