Definitions

  • the present invention relates to a profile element, which is pivotally connectable to each adjacent further profile elements to form a roller shutter and having a front and a back, which are spaced apart and between which at least one cavity is arranged, in which a introduced into the front wall Opening opens and in which a sound-absorbing material is arranged.
  • Such a profile element is z. B. from DE 30 32 946 known.
  • the profile elements are hollow profiles which are filled with a sound-absorbing material. The interior facing the front side is perforated to allow penetration of the sound.
  • the sound is to penetrate through the plurality of perforations in the profile element and penetrate into the underlying sound-absorbing material that fills the cavity of the profile element.
  • the sound-insulating properties of such profile elements can not always meet the demands placed on them.
  • the object is therefore to improve a profile element of the type mentioned, in particular with regard to the sound-insulating properties.
  • the object is achieved by a profile element of the type mentioned, in which the sound-absorbing material is part of at least one soundproofing element, which is movable at least in the region of the opening to the opening and away from it.
  • This solution is simple and has the advantage that the sound can penetrate through the opening in the interior of the profile element and spread there.
  • the soundproofing element does not completely fill the cavity due to its design and is movable away from it at least in the region of the opening towards the opening, the sound-insulating element can already be spaced from the front wall when the sound penetrates, or it can be spaced apart by the sound pressure. Through the distance between the sound-insulating element and the front wall, the sound propagates in such a way that it comes into contact with at least a majority of the surface of the sound-absorbing element and is absorbed. Compared to conventional shutters, in which the cavity is completely filled by the sound-absorbing material, the soundproofing properties of the roller shutter can be significantly improved.
  • the profile element according to the invention can be realized inexpensively.
  • the sound-absorbing material may be a fiber material. With such materials can be easily achieved cost-effective sound-absorbing properties.
  • the sound-absorbing material is a non-woven material.
  • Nonwoven material is characterized by very good sound-absorbing properties and good processability.
  • the soundproofing element can be formed by a membrane, preferably made of plastic. With such a membrane can be absorbed depending on the material targeted desired sound frequencies.
  • only one opening can be provided in the front wall when viewed in cross-section.
  • the inventive design of the soundproofing element with only one opening in cross-section can be in the longitudinal direction of the profile element reduce the number of openings in the profile element and simplify the production.
  • the width of the opening is less than a third and more than one-tenth of the width of the front wall, preferably less than a quarter and more than one-eighth. It has been shown that cost-effective sound insulation effects can be achieved with these specifications.
  • the distance of the openings is less than or equal to the extent of the opening in the longitudinal direction of the profile element.
  • the extent of the opening in the longitudinal direction of the profile element is less than or equal to twice the extent of the opening seen in the cross section of the profile element.
  • a further opening may be provided on the rear wall, a further opening.
  • a further opening which opens into the cavity or a further cavity of the profile element, the soundproofing properties of the shutter can be further improved.
  • At least one intermediate wall can be provided between the front wall and the rear wall. This also makes it possible to further improve the sound properties.
  • the intermediate wall is arranged such that between the front wall and intermediate wall at least a first cavity and between the rear wall and intermediate wall at least a second cavity is formed.
  • the soundproofing properties can also be improved.
  • the intermediate wall has at least one opening which connects the two cavities together. It may be advantageous if the opening of the intermediate wall is aligned with the opening of the front wall or the rear wall. In this way, the sound can pass completely through the roller shutter, being largely absorbed on its way through the soundproofing element.
  • the soundproofing element extends over the entire length of the profile element. This can simplify the production.
  • the hollow profile can have fastening devices for fastening the soundproofing element. This can prevent unwanted slippage of the soundproofing element.
  • the fastening devices can have bead receptacles and the soundproofing element can have a beaded edge, with which it can be fastened in the bead receptacles. This allows a positive connection between the profile element and sound insulation element can be ensured.
  • the profile element may be formed in at least two parts in a first profile section, which has the front wall and a second profile section, which has the rear wall. As a result, the installation of the soundproofing element can be simplified.
  • the soundproofing element can be inserted into the second profile section and subsequently the first profile section can be placed in order to surround the soundproofing element.
  • the intermediate wall is attached to the second profile section.
  • the fastening device is attached to the second profile section. Thereby, the fastening of the soundproofing element can be simplified.
  • the first profile section can be connectable by a latching device with the second profile section.
  • first profile section is latch-like latched onto the second profile section.
  • the intermediate wall is formed by a profile insert which is arranged between the front wall and rear wall.
  • the profile insert has support sections over which it is supported between the front wall and the rear wall, a secure hold of the profile insert can be ensured.
  • the membrane may be firmly connected to the profile insert.
  • FIG. 1 shows the profiled element 1 according to the invention in a sectional view.
  • the profile element 1 is formed by a first profile section 2, which has a front wall 3 and a second profile section 4, which has a rear wall 5.
  • the first and second profile sections include a cavity 6.
  • the first and second profile sections can, for. B. made of plastic and be prepared by extrusion in a known manner.
  • the first and second profile section may consist of different materials or the same materials. It is also conceivable, the first and second profile sections z. B. made of aluminum.
  • the front wall 3 has an opening 7, which opens into the cavity 6.
  • a soundproofing element 8 is arranged, which consists of a fiber material.
  • the soundproofing element 8 consists of a nonwoven material.
  • a further opening 9 is provided, which is aligned with the opening 7.
  • two further cavities 10 and 11 are formed in the second profile section 4. The cavities 10 and 11 are closed when viewed in cross section.
  • the second profile section in the illustration in Figure 1 on the right side via a connecting means 12 which has a fastening bead 13 which is hingedly connected via a film hinge 14 with the second profile section.
  • a fastening receptacle 15 On the left in Figure 1 side of the second profile section is a fastening receptacle 15, the inner dimensions of which substantially correspond to the outer dimensions of the fastening element 13.
  • the fastening element 13 of an adjacent profile element can be brought into engagement with the fastening receptacle 15 in a known manner.
  • the first profile section is designed in the illustration in Figure 1 on the left side substantially hook-shaped with a hook-shaped portion 16 which engages around a holding portion 17 of the second profile section 4.
  • the first profile section 2 On the right side of the first profile section 2 in FIG. 1, the first profile section 2 has a latching lug 18 which engages a latching receptacle 19 of the second profile section 4.
  • the first profile section 2 is made of an elastic material and can be mounted on the second profile section 4 by first inserting the latching lug 18 into the latching receptacle 19 and then snapping it onto the holding section 17. The dimensioning is chosen so that the first profile section 2 is snapped onto the second profile section 4 with a slight bias.
  • the two openings 7 and 9 are substantially circular and have substantially the same dimensions. In the illustration, the width or the diameter is approximately one quarter of the total width of the front wall.
  • openings and elongated openings can be used, wherein the length in the longitudinal direction of the rod, that is perpendicular to the representation in Figure 1 corresponds to at most twice the width of the opening.
  • a plurality of openings are provided, which are regularly spaced from each other, wherein the distance between adjacent openings is less than or equal to the width of an opening in the illustration in Figure 1.
  • Such an arrangement of openings is z. B. shown in Figure 6.
  • the dimensions of the soundproofing element 8 are chosen so that its height H g in the illustration in FIG. 1 is smaller than the height H H of the cavity 6.
  • the height of the soundproofing element is about 15% smaller than the height of the cavity, thereby to ensure at least in the region of the opening 7 a mobility of the soundproofing element 8 in the axial direction of the opening. Since when using the shutter this is usually wound onto a roll, or the front wall is located in a vertical plane, it may happen that the soundproofing element 8 abuts against the inside of the front wall 3. Due to the sound pressure, however, it can be moved away from the front wall again.
  • the width of the soundproofing element can be dimensioned such that it is slightly narrower than the inner width of the cavity 6.
  • the width of the soundproofing element 8 is at least 10% narrower than the inner width of the regions of the cavity 6 or the second profile section adjacent to the soundproofing element 8.
  • a roller shutter is formed by telescoping fasteners 13 in mounting receptacles 15 each adjacent profile elements. This can be performed in a known manner in lateral guide rails and wound on a curved rail or a roll. This is known from the prior art.
  • the front wall 3 faces the interior. The sound from the interior passes through the opening 7 into the cavity 6 and can be absorbed there by the sound-absorbing material of the soundproofing element 8. Due to the design of the soundproofing element 8 is formed between the front wall and soundproofing element 8, an air gap through which the sound can propagate in the cavity 6, thereby using the entire surface of the soundproofing element for absorbing the sound.
  • the soundproofing element is movable at least in the axial direction of the opening in the region of the opening, a good acoustic decoupling between the soundproofing element 8 and the profile element is achieved. If the soundproofing element 8 comes into contact with the front wall 3 due to the rolling up and unwinding of the shutter, the sound pressure of the penetrating sound can push back the soundproofing element to thereby develop the sound-absorbing effect.
  • the sound in the solution according to the invention can spread better in the cavity, thereby making better use of the sound-absorbing properties of the soundproofing element 8. In addition, this can reduce the number of openings in the front wall.
  • the assembly of the profile element according to the invention is facilitated.
  • the soundproofing element 8 z. B. are introduced laterally in the profile element. Since it is only loosely received in the cavity, it can be easily introduced into the profile element.
  • the soundproofing properties can be further improved. Due to the design of the soundproofing element 8, the soundproofing element 8 is also designed to be movable relative to this opening. This design allows further reflections of the sound in the soundproofing element, wherein the sound can emerge from the cavity 6 through the opening 9 in a greatly attenuated and damped form.
  • the second embodiment has an intermediate wall 20, which is formed integrally with the second profile section.
  • the intermediate wall 20 also has an opening 21 which is aligned with the openings 7 and 9 and of the same dimensions. Through the intermediate wall 20 creates a further cavity 22 in the profile element.
  • a membrane made of plastic, preferably polypropylene, is used as the soundproofing element 8.
  • the soundproofing element 8 of the third embodiment has laterally bead edges 23, which are received in bead receptacles 24 of the second profile section 4. This results in a positive connection between the soundproofing element 8 and the second profile section 4. Due to the design of the soundproofing element 8 of the third embodiment, the soundproofing element 8 is under prestress and forms a membrane. Between the soundproofing element 8 and the intermediate wall 20 is another cavity. The design of the third embodiment, the vibration behavior of the soundproofing element 8 can be improved. In addition, its location within the cavity 6 is precisely defined.
  • the fourth embodiment has a soundproofing element 8, which is designed as a membrane.
  • the soundproofing element 8 is also made of plastic and attached to a profile insert 25, which forms a membrane carrier.
  • the profile insert has support portions 26, with which it is supported within the integrally formed profile element 1.
  • the support portions 26 are under slight bias, thereby ensuring a secure fit of the profile insert in the profile element 1.
  • the membrane can be produced with the profile insert, for example by coextrusion.
  • FIG. 5 shows a further, fifth embodiment of the invention.
