Definitions

  • the invention relates to a device for securing the position of two components, according to the preamble of claim 1.
  • the link elements having a frame which runs around the end face and has holding legs which are bent into the plane of the link surface and which form the holding edges.
  • the width of the holding legs and thus the mutual distance between the holding edges to be determined by the connecting devices against one another is largely irrelevant, so that very considerable dimensional tolerances could be permitted here.
  • Higher accuracy requirements with regard to the width of the holding legs are therefore only to be made in the manufacture of such frames for scenery elements in order to be able to use the known connecting clips with elastic tolerance compensation, which obviously leads to a disadvantageous narrowing of the manufacturing possibilities for the frames of such scenery elements.
  • a device corresponding to the preamble of claim 1 is also known from US-A-4016689, which is prior art according to Art. 54.2 EPC.
  • the invention has for its object to provide a connecting device of the type outlined in the preamble of claim 1, with which considerably larger tolerance fluctuations in the distance between the two holding edges to be determined against one another can be accepted without the mutual securing of the components caused by the connecting device affect.
  • each of the connecting elements with its own bearing section can be easily attached to the associated holding edge, regardless of its specific position in individual cases.
  • the two connecting elements set in this way can optionally be pressed towards each other by hand in such a way that the latching and counter-latching means come into mutual engagement in the overlap region of the respective connecting sections or into the engagement position that corresponds to the distance between the end-side bearing sections and thus between corresponds to the holder edges of the components.
  • the locking engagement achieved in this way secures this position against tensile loads such as occur when the two components or their holder edges are to be removed from one another.
  • the connecting elements of the connecting device automatically come into that locking engagement of the latching and counter-latching means, which in individual cases produces the desired clamping effect between the two holder edges, regardless of whether they have a larger or smaller mutual distance.
  • a connecting element designated overall by 1, of a connecting device according to the invention, which is illustrated in FIG. 3 in use, consists of a bearing section 2 and a connecting section 3, which in turn comprises a main body 4, a retaining tongue 5 and has a locking tongue 6.
  • the entire connecting element is made from a flat sheet metal sheet made of sheet steel with a thickness of between 0.5 mm and 1 mm, for example, by means of appropriate bends and bends.
  • the same reference numerals as in the finished connecting element 1 according to FIG. 2 are used to designate the different areas of the punching board according to FIG. 1 in order to facilitate the assignment.
  • the bearing section 2 is bent into the groove-like shape shown in FIG. 2, with which it holds the holding edge 7 (see FIG. 3) of the component 8, which in the example case is on the frame of a Is formed, engages behind positively and so the connecting element 1 is stored there clean. Furthermore, in the connection area between the main body 4 of the connecting section 3 and the retaining tongue 5, an offset 9 is attached such that the retaining tongue 5 is offset from the plane thereof in the direction of the bending of the bearing section 2 approximately by the sheet thickness of the punching board or the main body 4. As a result, in the assembled position of the connecting device shown in FIG.
  • the retaining tongue 5 of the one connecting element 1 can be inserted essentially in a parallel position under the main body 4 of the opposite connecting element 1.
  • an edge strip, designated 6a, of the die-cut plate on the side of the connecting section 3 opposite the bearing section 2 is angled by approximately 90 ° from the plane of the main body 4, in the same direction in which the offset 9 and the angled section of the bearing section 2 lie.
  • a free front part of the edge strip 6a is bent in the manner shown in the drawing in the direction of the bearing section 2 and thus forms the latching tongue 6 pointing towards the bearing section 2 and resilient to a certain extent in this direction.
  • the holding tongue 5 On the side facing away from the latching tongue 6, the holding tongue 5 has a toothing 10 which is produced in one operation by the punching tool. If two connecting elements 1 of the type shown in FIG. 2 are now attached with their bearing sections 2 to mutually opposite holder edges 7 of the components 8, then, as FIG. 3 illustrates, there is an overlap of the connecting sections 3 with a suitable distance between the mutually opposite holder edges 7 of the two connecting elements 1 in an overlap area 11, the retaining tongue 5 of the one connecting element 1 engaging under the main body 4 of the connecting section of the opposite connecting element 1.
  • each retaining tongue 5 come into the area of the tip of the latching tongue 6 of the opposite connecting element 1, the distance a between the tip of the latching tongue 6 of a connecting element 1 and the side edge 10a of the associated retaining tongue 5 opposite the teeth 10 being chosen to be slightly smaller than the width b of the holding tongue 5 measured in the same plane.
  • each holding tongue 5 is guided by the side edge 10a of the holding tongue 5 of the opposite connecting element 1 opposite the toothing 10 and pressed with its toothing 10 onto the tip of the latching tongue 6. If the two connecting elements 1 are moved towards one another, the latching tongue 6 deflects resiliently, while the latching tongue 6 positively locks due to its inclined position when the connecting elements 1 are to be pulled apart again from the position shown in FIG. 3.
  • the latching tongue 6 together with the edge strip 6a also forms a spacer with which the end region of the connecting section 3 lying in the area of the retaining tongue 5 is pressed off by the components 8, in the example of retaining legs 12 the metal frame of link elements. This ensures that the front section of each retaining tongue 5 is guided snugly on the lower surface of the main body 4 of the opposite connecting element 1 and is thus kept clean in the effective area of the tip of the latching tongue 6. A bending of the connecting device in the position according to FIG.
  • the connecting elements 1 can be properly attached to these even with considerable dimensional fluctuations in the distance between the holding edges 7 and pressed together to such an extent that the desired position-securing connection between the holding edges 7 or the holding legs 12 results and a loosening of the neighboring components 8 becomes impossible.
  • a suitable material for the sheet metal of the punching plate, for example spring steel or V4A steel, and a correspondingly robust shape for the toothing 10, it can be achieved that the strength of the assembled connecting device in the illustration according to FIG. 3 is that of the areas covered by the connecting device of the components 8 at least reached, so that there is a completely secure connection.
  • the assembly of the connecting device can generally be done very easily by hand and a simple tool such as pliers is only required if the holding edges 7 are to be pressed together under tension for some reason.
  • the back of the connecting device which is visible in FIG. 3 is flat, that is to say it has no projections, bulges or the like, which could interfere with stacking or during transport and, if appropriate, would be subjected to deformations which impair the functional reliability of the connecting device.
  • the overall height of the connecting device can be kept in the range of a few millimeters, for example 2.5 mm, so that there is only a slight thickening at the location of the connecting device along the holding leg 12 or the like. Since the two connecting elements 1 shown in FIG. 3 are of completely identical design and are only arranged in opposite directions, in addition to the simple manufacture, simple storage and immediate availability of all individual parts required for the connecting device result.
  • latching means such as the teeth 10 or also in a different design could also be provided on only one side of the connecting device, while on the other side only counter-latching means in the form of one or more latching tongues 6, counter teeth or in another design are arranged.
  • the connecting device is constructed from at least two connecting elements, each with a suitable bearing section 2, which, by means of a suitable arrangement of latching means and counter-latching center, allow a variable distance to be bridged between opposing holder edges 7 with their connecting sections 3 and by one with sufficient force locking engagement to secure the respective distance between the holder edges 7.
