Definitions

  • the present invention relates to a snap frame according to the preamble of claim 1.
  • Frames of this type are known, for example, from US Pat. No. 3,310,901 and DE-OS 28 18 138. They are characterized in that the frame sections are held in their closed and open positions with a snap action due to the geometrically predetermined clamping and preloading of the springs.
  • the springs are designed as leaf springs which, under pressure bending, bear on the one hand on corresponding supports on the front side and on the other hand on supports on the rear profile strips. Due to the mentioned clamping, the front profile strip can only be opened against the action of a spring force.
  • the known leaf springs are on the one hand relatively expensive because a relatively large amount of material is required.
  • the known concept is also expensive because the assembly of the leaf springs is complicated.
  • the object on which the present invention is based is to provide a snap frame of the generic type which, viewed overall, is simpler to use is to be installed and in which the springs for mutual bracing of the profile strips are designed more simply.
  • the shape of the springs themselves can be different (see claims 4 to 7). It is only important that the springs can spring in their bending plane.
  • FIG. 1 shows a rectangular folding frame 1 consisting of four frame sections 2, 3, 4, 5 which are connected to one another in the corner area and which is glued onto an area, for example a window pane, as an open frame or hung with a back part as a folding display frame is.
  • the frame sections 2, 3, 4, 5 are mitered in the corner areas.
  • the front profile strips that can be swung out, for example, from the plane of the frame 1 (i.e. the drawing plane) can be seen, which stand up on the rigid profile frames forming the rear profile strips (display snap frame) or cover them on all sides (open window snap frame).
  • the frame sections 2, 3, 4, 5 thus form a back frame which is provided with a rear face or else an open snap frame 1 in which a display panel or the like can be inserted and clamped.
  • FIG. 2 shows the cross section of a frame section 2, 3, 4, 5 of a so-called display snap frame, namely in the closed position and - dash-dotted - in an unstable open position of this snap frame 1 with an integrated back part, corresponding to the same cuts AA, BB, CC and DD of the snap frame 1 according to FIG. 1.
  • the frame sections 2, 3, 4, 5 each consist of a rear profile strip 10 and a front profile strip 11, which are connected to one another in an articulated manner and are non-positively coupled to one another via springs 7.
  • the rear profile bar 10 consists in cross section of an L-profile, the long web of which serves as a support for the mentioned back part 6, which in turn is a support for a display panel 8 or the like.
  • the short web has a concave support joint sleeve 12 at the end for supporting the spring 7; Furthermore, the short webs on the side opposite the long web have a projecting hinge pin 13.
  • this hinge pin 13 On this hinge pin 13 is a complementary hinge sleeve 14 of the front profile bar 11, which in principle has the cross-sectional shape of a U.
  • the transverse web of this U is parallel to the back part 6 of the rear profile strip 10 or to the long web of the L.
  • the one free leg of the U has the joint sleeve 14 mentioned and the second free leg of the U is in the direction of the long web of the L and thus directed towards the rear profile strip 10.
  • the mutual coordination of the profiled strips 10 and 11 with one another, taking into account the spring 7, is as follows:
  • the spring 7 is supported on the one hand in the concave support joint sleeve 12 of the rear profile strip 10 and on the other hand in a support lug 15 on the inside of a support edge 16 of the second free leg of the U.
  • the front profile bar 11 is supported by the spring tension of the spring 7 by means of the joint sleeve 14 on the rear profile bar 10.
  • the assignment between the from the hinge pin 13 and the GElenk sleeve 14 existing swivel between the front and rear profile strip 10 and 11 and the lever-like assignment between the supports of the spring 7 on the support joint sleeve 12 and the support nose 15 are such that in the - shown in Fig.
  • the circular arc a) corresponds to the swivel circle of the front profile bar 11,11 'around the hinge pin 13; the circular arc b) would correspond to the swiveling circle of the spring 7 around its support joint sleeve 12 if its distance dimension corresponding to the closed position would remain constant.
  • the length of the long web of the L of the rear profile bar 10 and the width of the U of the front profile bar 11 are coordinated so that the latter stands up in the closed position on the L-profile.
  • the front edge of the corresponding free leg of the U-profile ultimately lies in the plane of the mentioned back part 6 of the rear profile strip 10 on the display panel 8.
  • a display panel 8 can thus be braced against the back part 6 via the contact edge 16 of the front profile strip 11 projecting towards the interior of the frame.
  • the spring 7 which braces the front and rear profile strips 10 and 11 against each other as a wire spring bent in one plane between the concave support joint sleeve 12 of the rear profile strip 10 and the support lug 15 of the front profile strip 11.
  • the spring 7 is configured so that it can bend in this bending plane - i.e. perpendicular to the plane of the drawing.
  • the hinge axis between the profile strips 10, 11 on the one hand and the line of action determined by the spring 7 between the support joint sleeve 12 and the support nose 15 on the other hand are matched to one another in such a way that the geometric length of the line of action is shortened when the front profile strip 11 is pivoted out. This creates a force component of the spring 7, which braces the front profile bar 11 against the rear profile bar 10.
  • the spring 7 is compressed in the bending plane so that it bulges or dodges in the longitudinal direction of the profile bars 10 and 11 and is compressed transversely thereto (see arrows in Fig 3).
  • dash-dotted lines indicate an unstable opening position of a frame section.
  • the spring 7 ' has a shortened in relation to the closed position line of action, ie transverse expansion in the bending plane.
  • mutually complementary stop means are provided on the front and rear profile bar 11,11. These consist of a stop lug 18 worked on the outside of the joint sleeve 14 and a corresponding stop surface 19 or stop edge on the outside of the short leg of the L of the rear profile strip 10. In the open position, the stop lug 18 'is then against the stop surface 19, so that the front profile bar 11 'no longer open ie can be pivoted away.
  • FIG. 3 shows a perspective view of two mutually adjacent open frame sections 2 and 3 or 3 and 4 or 4 and 5 or 5 and 2.
  • the rear profile strips 10 form a closed rectangle (see Fig. 1), the back of which is formed here by the back part 6 '.
  • the front profile strip 11 is articulated via the swivel joint consisting of the joint sleeve 14 and the joint pin 13; the frictional engagement between the respective pairs of profile strips is mediated by the springs 7.
  • these springs 7 have an approximately elliptical basic shape, the longitudinal axis of which extends axially parallel to the profile strips 10, 11 and the transverse axis thereof - compare FIG. 2 - transverse to the longitudinal axis mentioned.
  • the spring 7 is supported on the one hand in the support joint sleeve 12 provided along the rear profile strip 10 and on the other hand in the support nose 15 provided on the front profile strip 11 on the support edge 16.
  • the - elliptical - spring 7 is deformed in such a way that the longitudinal axis is temporarily larger and the transverse axis is briefly and simultaneously shorter (compare the arrow information in FIG. 3).
  • the elliptical basic shape can in principle be closed or slotted on one contact side in the support joint sleeve 12 or the support nose 15.
  • FIGS. 4 to 6 Further basic forms of the spring 7 are shown in FIGS. 4 to 6, it being explicitly pointed out that further basic forms and mixed forms of these basic forms are also possible.
  • Fig. 4 shows a spring 7 with the basic shape of an open loop.
  • the two wire ends 20 form a scissor angle of approximately 150 degrees and are in contact with one another, so that the flat bending surface is ensured - at least approximately.
  • the spring 7 shown in FIG. 4 with the wire ends 20 on the one hand and the opposite rounding on the other hand, bears against the complementary recesses of the profile strips 10, 11 on the front and rear, indicated by dash-dotted lines.
  • FIG. 5 shows a spring 7 with the basic shape of a triangle with two triangular sides formed by the bent wire and one open side, to which sliding feet 21 are connected, if necessary.
  • the open side, on the one hand, and the triangle tip, on the other hand bear against the complementary recesses of the profile strips 10, 11 on the front and rear, indicated by dash-dotted lines.
  • Fig. 6 shows a spring 7 with the basic shape of an isosceles trapezoid, the two parallel sides in the assembled state against the complementary recesses of the - indicated by dash-dotted lines - front and rear profile strips 10, 11.
  • One of the parallel trapezoidal sides can - as drawn - be slotted.
