Definitions

  • the invention relates to an end piece for the end closure of hollow profile bars of a roller shutter curtain, of which adjacent ones are articulated to one another on opposite longitudinal edges in such a way that they have a hook element on one side and a receiving element for the hook element of an adjacent bar on the second side.
  • a closing part covering the side edge region of a bar and a holding part arranged essentially at right angles to the closing part, which can be positively connected to the bar in such a way that the holding part can be inserted between the two broad sides of the roller shutter curtain essentially in the longitudinal direction of the assigned bar and that Holding part on its two sides facing the rod broad sides has latching elements which can be elastically latched into corresponding openings in the rod broad side walls.
  • FIGS. 1 and 2 are taken from this document and expressly referred to the explanations made for this and for further developments of the end piece there, since many individual features of the present invention are known therefrom.
  • This known end piece requires a precise dimension of the distance between the openings in the broad sides of the rod for receiving the locking elements of the holding part and the front edge of the rod or allows tolerances only in the direction of increasing this distance, because when reducing the insertion of the locking elements into the openings is no longer possible by inserting the end piece into the rod.
  • the invention is intended to achieve a reliable fit of the end piece in the associated rod end and to prevent canting.
  • the holding part when inserted in the hollow profile rod and engaging with respect to its latching elements in the corresponding openings in the broad side of the rod, via the end part and a spring-elastic region increasingly deformed in the course of the insertion of the holding part on the associated end-side rod edge region with corresponding spring-elastic tensioning is supported.
  • a first preferred basic embodiment of the end piece for solving the problem is characterized in that a spring-elastic connecting part is switched on as the spring-elastic region between the holding part and the end part, which connecting part is displaced in the course of a displacement of the holding part with respect to the end part supported for the end edge edge of the associated rod is stretched resiliently in the longitudinal direction of the rod.
  • the resiliently displaceable between the end part and the holding part makes it possible for the latter to rest when the end part is in contact with the end face.
  • Edge of the rod under elastic tension of the connecting part to continue to insert into the rod until the locking elements snap into the associated openings, whereupon after the insertion process under the elastic pretension of the connecting part, the undercut locking elements, preferably located in the locking area opposite the end part, at the opening edges engaging in these undercuts apply under pressure, so that there is a permanent tension between the locking elements engaging in the openings of the rod and the end part resting on the end face edge of the rod. Under this elastic tension, the end piece sits so far without play in its latched insertion position, even if the spacing between the end face edge and the associated openings of the rod is not dimensioned exactly.
  • connection part consists of two bow-shaped connection zones, which are formed in particular in the narrow-side connection areas between the holding part and the end part.
  • holding part is preferably provided with an actuating section which projects into the end part and which can be reached from outside.
  • a second preferred basic embodiment of the end piece for solving the task consists in that in at least one of the longitudinal end regions of the end part pointing in the plug-in state in the direction of movement of the roller shutter curtain, a spring-resilient part is provided as a spring-elastic region, which part is inserted in the undeformed state before being plugged in The contact plane of the locking part protrudes in the direction of insertion.
  • the Resilient parts of adjacent end pieces act on the front edge areas of the hinged rods in the hinge area, whereby the interlocking roller hinge areas of adjacent bars are spring loaded in the hinge axis direction so that they cannot move against each other in this direction.
  • the resilient parts also serve to align the successive bars in the direction of movement of the armor.
  • the resilient part is designed in the manner of a leaf spring, the "clamped" end of which is directed towards the longitudinal center of the closure part and the resiliently yielding end region - preferably of thickened design - is directed towards the one longitudinal end region of the closure part.
  • This end region and thus the whole resiliently resilient part can be arranged within the outer edge of the closure part or protrude into this edge region and thereby break through it.
  • resiliently resilient parts are arranged in both longitudinal end regions of the closure part, preferably in an end region within the border and in the other breaking this border.
  • the resilient part of the first basic embodiment of the end piece is preferably formed in one piece with the closure part and the holding part, as can be seen from the exemplary embodiment according to FIG. 4.
  • the resilient part (s) of the second basic embodiment are preferably formed in one piece on the closure part.
  • tongues protruding in the direction of insertion are preferably formed on the holding part, on the free ends of which the latching elements are formed which engage in the inserted openings of the broad side walls of the rod under spring-loaded prestressing of the tongues.
  • the tongues can be formed on the side of the holding part facing away from the end part in an anchoring manner, the latching elements being located on the outer sides of the two anchor ends.
  • the tongues on the end part facing away from th side of the holding part can be formed in a fork-like manner, the latching elements being located on the outer sides of the two fork ends.
  • webs facing the broad sides of the rod can be formed on the holding part, which webs form a groove between them and the latching elements are arranged on their outer surface, in particular tapering in extensions.
  • the holding part, the end part and the connecting part in the basic first embodiment can form a coherent, one-piece body, which consists of a corresponding resilient material at least in the area of the tongues or the extensions and the connecting part.
  • Several, preferably five, tongues or latching elements can be formed on each of the two sides of the holding part.
  • the locking elements can be circular or oval in cross section.
  • the locking elements can have a bevel on their side facing away from the end part, and finally the locking elements can be undercut on their side facing the end part in a particularly preferred embodiment.
  • Figures 1 and 2 known versions of end pieces and hollow rods of the type in question
  • Figure 3 shows in different views a first embodiment of the end piece according to the invention
  • Figure 5 in different views a further embodiment of the end piece according to the invention;
  • Figure 6 in different views of a last embodiment of the end piece according to the invention.
  • Figures 1 and 2 are taken from the aforementioned known document and also illustrate for the present invention hollow profile rods which are to be closed at the end with end pieces.
  • FIG. 3 shows in different views a first exemplary embodiment of an end piece designed according to the invention in a top view of the side of the end piece facing the rod, including its side view and again a top view from outside the rod when the end piece is inserted; further an end view, a section along the line B - B and a perspective view of this embodiment.
  • Figure 4 shows a section along the line E - E after the line of the same name from the first-mentioned top view folded by 180 °. From the drawings, the shape of the one-piece end piece from the holding part 12, the end part 13 and the connecting part 41 results.
  • the tongues formed on the holding part 12, which are designed to strive from the end part into the interior of the rod, are fork-shaped, the fork branches are each approximately formed on the broad sides of the bars.
  • the width of the forks in the area of the locking elements is wider when not in use than the clear width between the two broad sides of the bars.
  • Correspondingly inclined fork end surfaces enable the holding part to be inserted while the respective fork tines are deformed elastically towards one another, so that the locking elements formed on their outer sides snap into the openings of the rod (not shown here) in a resilient manner.
  • the holding part By pressing the actuating section 50, the holding part is secured relative to the end part with a resiliently elastic deformation of the connecting zones 42 and 43, which form the connecting member 41 - FIG. 4 - ensures that when the actuating section is released, the holding part is in relation to that on the front edge of the rod abutting end part is springed back on the connection zones 42 and 43, so that the undercuts 51 of the locking elements are pressed against the engaging opening edges - not shown. A certain pretension remains between the holding part and the end part as well as between the fork ends and the inside of the broad sides of the bar - not shown receive. Further results from the corresponding claims, in particular with the help of the reference numerals.
  • FIG. 5 shows a second exemplary embodiment, in which tongues projecting into the interior of the rod are formed on the holding part and are designed in the form of anchors in their strutting regions.
  • the locking elements are arranged on the outgoing arm legs 48 and 49.
  • the design of this embodiment corresponds to that of FIGS. 3 and 4.
  • FIG. 6 shows an exemplary embodiment in which instead of the a resilient connecting part between the holding part and the closure part, a resilient area in the form of two resilient parts is provided, which are each arranged in one of the opposite longitudinal end regions of the closure part.
  • FIG. 6 shows, in different views, a second exemplary embodiment in a top view of the side of the end piece facing the rod, including its side view and again a plan view from below of the rod with the end piece inserted; Furthermore, an end view, a section along the line A - A, a section along the line B - B from the aforementioned side view, a section C - C from the top view drawn above, and a perspective view of this exemplary embodiment.
  • the drawings show the shape of a one-piece end piece produced from the holding part 52, the closure part 53 and resiliently compliant parts 54 and 55 formed on the latter in the longitudinal end regions thereof, which are exposed in one piece starting from the longitudinal center in the manner of leaf springs from the closure part.
  • a resilient part 54 is exposed in a U-shaped manner from the closure part or its base and remains within the border 56 of the closure part 53 with regard to its elastically deformable end , as can be seen in particular from the top view of FIG. 6.
  • the end of the part 54 resiliently resilient in the manner of a leaf spring is thickened 57 and protrudes in the direction of the holding part from the closure part, as can be seen from the side view and the sectional view C - C in FIG. 6.
  • the resilient part 55 in the region of the other longitudinal end of the closure part 54 likewise protrudes from the longitudinal center and extends through the edge region of the closure part, as is particularly the case in the top view, the side view and also the section along the line C - C in the left longitudinal end region of the closure part 54 reveal.
  • This resilient part 55 is also thickened at 58 at its free leaf spring end.
  • the two resilient parts 54 and 55 when the holding part 52 is pushed into the assigned position in the associated rod end, engage with their thickened leaf spring ends 57 and 58 in a manner not shown on the front edges of the associated rod spring end under elastic prestress, namely in the area of Hinge connection to the respective adjacent rod, which on the one hand holds the positioning of the closure part 53 and the holding part 52 resiliently and on the other hand ensures the succession of the rods in a correspondingly aligned manner in the direction of movement of the rod roll armor, ie a displacement of two adjacent bars in the hinge axis direction is thus avoided by the resilient parts 54 and 55 acting on both sides of the end pieces inserted into the opposite bar end pieces on both sides of the roll-up armor.
  • the design of the holding part can be made both in accordance with the example according to FIG. 3 and that according to FIG. 5; In the present case, the holding part is designed similar to that according to Figure 3.
