Definitions

  • the invention relates to a two-part shutter rod of the type specified by claim 1.
  • the two profile parts are designed as extruded profile shells to form a cross section with two hollow chambers.
  • the two profile shells are connected to one another via three sliding guides, which are provided for the upper and the lower cross-sectional end and, in a different design, for a support strip arranged for the simultaneous separation of the two hollow chambers.
  • the sliding guides are designed at the same time so that, given a certain intrinsic elasticity for the plastic of the inner wall, the two profile shells can also be plugged together and thus a technically complicated assembly shifting for the joining of the two profile shells is eliminated.
  • the sliding guides provided for connecting the two profile parts form a material weak point of the roller shutter, which is composed of such roller shutter slats.
  • This weak point is particularly noticeable in the fact that when larger temperature differences occur between the outside and the inside of the roller shutter, the outer wall of the roller shutter slats is then subject to greater thermal expansion than the inner wall due to the material, and thus the two profile parts one to loosen the sliding guides and last also experience a spread that leads to their complete loosening.
  • roller shutter slats Because the outer wall of these roller shutter slats is usually also relatively thin-walled for reasons of cost, it is therefore also subject to a stronger warp compared to the inner wall, which in the expansion up to the hook strips can then lead to the roller shutter easily jumping out of it side guide rails inclines.
  • Another disadvantage of these known roller shutter slats is their relatively low bending stiffness, so that, unlike with exclusively metallic roller shutter slats, it is hardly possible to produce roller shutters of a larger area with a width of, for example, 4 m.
  • the invention characterized by the claims solves the problem of designing a roller shutter rod of the type specified in such a way that it can also be used to manufacture large-area roller shutters with a surface stability comparable to the known aluminum roller shutters and at the same time improved thermal insulation, whereby for the assessment of these two criteria in addition
  • the manufacturing costs for the roller shutter rod also include a larger distance of, for example, 8.5 cm between the installed roller shutter and the window front to be protected.
  • the advantages achieved by the invention are essentially that with only two profile parts, a further wall is integrated into the roller shutter rod in such a way that with the marked sliding guide a greater flexural rigidity and at the same time an improved thermal insulation is obtained in that between the outer wall and the inner wall the roller shutter rod has an additional air cushion. It can therefore be made with such roller shutter slats also large-area roller shutters with the required greater surface stability, and then optimally at the same time the connection connections realized by the hook strips are designed such that the two via directly assigned sliding guides Profile parts are braced against each other and thus there is no risk of loosening even with extreme temperature differences between the outside and inside of a roller shutter.
  • roller shutter slat A preferred embodiment of the roller shutter slat according to the invention is shown in the drawing in a sectional view and is described in more detail below.
  • the roller shutter rod consists of an aluminum extruded first profile part 1 as the outer wall and a plastic extruded second profile part 2, which is designed as a closed hollow chamber profile and gives intermediate wall sections 3, which are at a distance from the outer wall and to that formed by the profile part 2 Inner wall 4 of the roller shutter bar are arranged.
  • the roller shutter slat is provided with an upper hook bar 5 and a lower hook bar 6, with which the connection to roller shutter slats of the same design, which is usual with a roller shutter, is realized.
  • the upper hook strip 5 is formed in one piece with the profile part 1 and has a baseboard 7 which is hidden by the visible surface of the outer wall and which is arranged in a cavity 8 of the upper end wall 9 of the profile part 2.
  • the cavity 8 opens into a guide groove 10 which is undercut by means of an inner bend 11 of the upper end wall 9 with respect to the cross section of the baseboard 7.
  • the skirting board 7 therefore, in cooperation with the guide groove 10, provides a sliding guide which is directly associated with the upper hook bar 5 and via which the two profile parts 1, 2 are connected to one another in a weatherproof manner.
  • the two profile parts 1, 2 are also connected to one another via further sliding guides, which consist of two support strips 12 formed integrally with the outer wall with a cross section T-shaped head part 13, guide grooves 14 in the chamber webs 15 of the profile part 2 and with adaptation to the cross section the head portions 13 are formed undercut retaining grooves 16.
  • the lower end wall 17 of the profile part 2 is also provided with a cavity 18, in which a further support strip 12 'of the outer wall for guiding a head part 13', which is also T-shaped in cross section, surrounds in a holding groove 16 ', with which the lower hook strip 6, which is formed in one piece on the profile part 2, is also directly associated with a sliding guide aligned in the longitudinal axis of the roller shutter rod.
  • a further sliding guide which is directly associated with the lower hook strip 6 or the receiving space for the upper hook strip 5 of a roller shutter rod to be connected, which is delimited by it, is formed by the cooperation of a retaining groove 19 undercut at the lower end of the profile part 1 with a head part 20 with a T-shaped cross section Support bar 21 is formed, which is formed at the mouth of the cavity 18 on the lower end wall 17 of the profile part 2.
  • the retaining groove 19 is formed from an angled portion 22 of the support strip 12 'and an inner angled portion 23 of the outer wall set back with respect to the lower edge of the profile part 1.
  • a locking projection 25 which is still formed on the lower end wall 17 of the profile part 2, also acts together in order to provide a locking connection for the two profile parts 1, 2 at this lower cross-sectional end of the roller shutter bar in addition to the sliding guides to obtain, which has an abutment in the inner bend 11 of the upper end wall 9 of the profile part 2, which cooperates with the baseboard 7 of the upper hook strip 5.
  • a mutual bracing of the two profile parts 1, 2 can therefore be obtained by this latching connection if the two profile parts have been joined together on the individual sliding guides.
  • the two profile parts 1, 2 are thus connected via the individual sliding guides transversely to the longitudinal axis of the roller shutter rod and via this latching connection additionally perpendicular to the longitudinal axis in a correspondingly reliable manner, so that such roller shutter rods can be used to produce a very stable roller shutter that is weatherproof and also is burglar-proof and provides great thermal insulation.
  • the upper hook strip 5 being formed in one piece with the outer wall, a separate formation can also be realized, taking into account the then reduced surface stability of a roller shutter manufactured with such roller shutter slats.
  • the sliding guide for the upper hook part 5 obtained by the skirting board 7 in cooperation with the guide groove 10 for a simultaneous connection of the two profile parts 1, 2 would only be replaced by a sliding guide of a corresponding skirting board of such a separately designed upper hook bar preferably on the outer wall in FIG a training comparable to the holding groove 19 and with the addition of a sliding guide in a training comparable to the head parts 13 and the holding grooves 16, in order for a connection of the two profile parts 1, 2 which is also directly assigned to the upper hook strip, for the upper cross-sectional end of the roller shutter bar to obtain.
  • the baseboard has a length which essentially corresponds to the length of the roller shutter rod, while on the other hand the hook part projecting upward above the upper cross-sectional end of the roller shutter rod consists of individual sections is formed with a shorter individual length compared to the length of the roller shutter rod, so as to obtain clear spaces between the individual sections of the hook part for incidence of light.
