Definitions

  • the present invention relates to an image holder for setting up with a hinged to the rear wall of the image holder support which is pivotable from a pivoted-rest position into a spread support position in which the support is held by a support holder.
  • Such picture holders are known several times in practice.
  • the support is glued or otherwise connected with such a picture holders in the middle of the image holder on the rear wall with a joint flap.
  • Approximately in the middle of the support designed as a tab support holder is glued, which is fastened with its other end to the rear wall.
  • This support bracket is often designed as a textile band. In the rest position, the support is folded against the rear wall of the image holder, while it is spread in the support position as far as allowed by the length of the support holder. The picture holder is then in its position of use on an edge and on the support.
  • the support would be in the suspended state of the image holder between the frame and the wall, whereby on the one hand, the image holder would not stand evenly from the wall and on the other the support would be seen. Since both are undesirable, it has been set in the selection of the frame for such picture holder on certain frame thicknesses, which were not allowed to be exceeded, otherwise the established picture holder assumes too strong a tendency or is too uncertain.
  • the invention is therefore an object of the invention to provide a picture holder of the initially mentioned kind, which assumes a secure state in the erected state, especially when the picture holder is surrounded by a frame.
  • the support is connected via a four-bar linkage with the rear wall of the image holder such that the support is arranged in the support position relative to the rest position to a longitudinal edge of the image holder swung out.
  • This has the advantage that the support is now moved in the rest position so far to the center of the rear wall of the image holder, that it has completely disappeared behind a possible frame of the image holder.
  • the support position In the support position, however, the support is so far shifted to the edge of the image holder, that the support can be widely spread, so that the picture holder can take a safe and at the same time upright.
  • this solution makes it possible that the supports can be made relatively short, without underneath the stability of the image holder suffers.
  • one side of the four-jointed support is formed by the support itself and the opposite side fixed as a base on the rear wall of the image holder, wherein the support is connected on the one hand via the support holder and the other via a rollover strap to the base side such that in the rest position, the base side and the flashover tab are arranged approximately in a plane parallel to the support and the support holder, while in the support position the flashover tab rests on the base side and the base side, the support holder and the support form a triangle.
  • the support is bistable, ie, a stable position is the rest position in which the support and thus the four-jointed support is pivoted flat to the rear wall of the image holder, while the other stable position is the support position in which the weight of Image holder ensures that the support holds the flap in a position in which it rests against the rest position of the support turned by 180 ° on the bottom of the four-jointed support. Since between the base side and the support, i. as well as between the flashover tab and the support an obtuse angle is formed, causes a part of the transmitted through the support standing force that the flashover tab is pressed in this position against the base side.
  • a preferred embodiment provides that the side formed by the support of the four-jointed carrier is formed shorter than the base side.
  • the spread angle of the support in the support position is about 45 °. This Absp Schwarzwinkel is achieved by a special selection of the length ratios of the individual sides of the four-jointed carrier.
  • the sides of the four-jointed support are plate-shaped, wherein the plate planes are arranged in the rest position parallel to the rear wall of the image holder.
  • the support and four-jointed carrier can be pivoted particularly flatly against the rear wall of the image holder.
  • the flat application of the support to the rear wall of the image holder is further promoted by the fact that in the support a recess is provided, in which the support holder is arranged in the rest position.
  • the support force causes the support is held stable in the support position
  • the joint which connects the support bracket to the base side, is formed bistable.
  • the spring is designed as against a joint edge of the support bracket pressing leaf spring.
  • the spring can then be kept relatively small.
  • the leaf spring between the base side and the rear wall of the image holder is fixed and has a projecting from the rear wall tongue which presses in the rest position against the hinge edge of the support bracket, which hinge edge is formed approximately at right angles to the column holder plane.
  • This has the advantage that the spring can be accommodated for a very space-saving and is located on the other outside of the four-jointed carrier, so that the support can be completely folded onto the base of the four-jointed carrier.
  • the joint edge is approximately at right angles to the column holder plane, in the rest position of the support thus formed approximately at right angles to the rear wall of the image holder, the tongue of the leaf spring is bent by more than 90 °, so that the tongue even then presses against the joint edge when the support at rest.
  • the support is held firmly in the rest position and can be converted from this only by applying a desired force in the support position.
  • the action of the leaf spring assists the support force transmitted by the support by exerting on the support support a torque which apparently turns it towards the base of the four-bar support.
  • the support can then attach to the picture holder when the bottom of the four-bar linkage carrier is formed by the rear wall itself.
  • a detachable joint is mounted between the support bracket and the support. This not only facilitates the production of the support and the four-jointed support but also the attachment of the four-jointed support on the rear wall of the image holder, since the base side is freely accessible for attachment. Only when the base side is attached, is connected via the releasable joint of the support bracket with the support.
  • a rectangular picture holder 1 with peripheral frame 2 is shown.
  • a support 4 is articulated on the rear wall 3 of the image holder 1 and can be swiveled from a swiveled-in rest position (cf., Fig. 4) into a splayed support position (see Fig. 3), in which the support is held by a support holder 5.
  • the support 4 is connected to the rear wall 3 of the image holder 1 via a four-bar support 6.
  • the support 4 forms one side of the four-jointed support 6.
  • the opposite side of the four-jointed support 6 is formed as a base side 7 and fixed to the rear wall 3 of the image holder 1.
  • the support 4 is connected approximately at its center via the support holder 5 with the lower end of the base side 7. Between the support 4 and the support bracket 5 is a hinge 8, while between the support bracket 5 and the base 7 a further hinge 9 is arranged.
  • the support 4 is also connected at its upper end via a rollover tab 10 hingedly connected to the upper end of the base side 7. Between the flashover tab 10 and the support 4, a support joint 11 is attached, while the flashover tab 10 is itself connected by means of a Studentsschlagsgelenkes 12 with the base 7.
  • the mobility of the joints 8, 9, 11 and 12 is such that in the rest position (cf., Fig. 4) the base side 7 and the rollover tab 10 lie approximately in a plane parallel to the picture holder rear wall 3.
  • the support 4 and the support bracket 5 are also in a plane and also parallel to the rear wall. 3
  • the flashover flap 12 rests on the base 7, so that the remaining part of the base 7, the support bracket 5 and belonging to the four-bar support 6 part of the support 4 form a triangle.
  • the sum of the lengths of the base side 7 and the flashover tab 12 must be equal to the sum of the lengths of support bracket 5 and the part of the support 4 belonging to the four-bar linkage 6.
  • the side of the four-jointed carrier 6 formed by the support 4 is formed shorter than the base side 7.
  • the flashover tab 10 is automatically shorter than the support bracket. 5
  • the Absp Dröving ⁇ which is the angle between the support 4 and the base 7 in the support position (see Fig.3), 45 °.
  • the choice of the length of the rollover tab 10 depends essentially on the frame width, since the degree of Nachau toschiebens the support 4 can be determined by the choice of length of the rollover flap 10.
  • the sides of the four-bar support 6, ie the support 4, the support bracket 5, the base 7 and the flashover tab 10 are plate-shaped, the plate planes arranged in the rest position parallel to the rear wall 3 of the image holder 1 are.
  • a recess 13 is provided, in which the support bracket 5 in the rest position (vgl.Fig.2) is arranged.
  • the joint 9 between the support bracket 5 and the base 7 is formed as a bistable joint by a spring 14 tries to push the support bracket 5 in the rest position.
  • the spring 14 is formed as a leaf spring and presses with a tongue 15 against the adjacent to the hinge 9 edge of the support bracket 5.
  • the main part of the spring 14 is disposed and fixed between the rear wall 3 and the base side 7 of the four-bar support 6.
  • the joint edge of the support bracket 5, which is denoted by the reference numeral 16 below, is formed approximately at right angles to the column holder plane. That is, in the rest position of the support 4, the joint edge 16 is aligned approximately at right angles to the rear wall 3 of the image holder 1.
  • the protruding from the tongue 14 tongue 15, however, is bent over more than 90 °, so that it still presses in the rest position of the support 4 against the joint edge 16 of the support bracket 5.
  • the tongue 15 of the spring 14 for applying the torque to the support bracket 5 has a lever travel which approximately corresponds to the plate thickness of the support bracket 5. With only very small spring travel, the spring 14 is able to set the support 4 with sufficient force both in the support position, as well as in the rest position.
  • the base side 7 may also be part of the rear wall 3 of the image holder 1.
  • the spring 14 is then fastened on the side of the rear wall 3 facing the image.
  • the joint 8 between the support bracket 5 and the support 4th can be detachable, zBals be designed as a plug connection, so that the support 4 and the four-bar support 6 unwound accept a band-shaped appearance and can be made accordingly from one piece.
  • the support 4 and the four-bar support 6 consist in the illustrated embodiment of a thermoplastic material.
  • the trained as a leaf spring spring 14 can be made of a piece Federstal.
  • the support 4 is gripped at its lower end and pulled away from the rear wall 3 of the image holder 1 on the lower frame. Due to the parallelogram-like configuration of the four-jointed support 6, the support 4 lifts off from the rear wall 3.
  • the support joint 11 at the upper end of the support 4 describes a circular path with a length of the flashover tab 10 corresponding radius around the rollover joint 12 around. The circular path is shown in dashed lines in Fig. 3. By this movement, the support 4 approaches the edge of the image holder. 1
  • the support bracket 5 pushes the lower part of the support 4 from the rear wall 3 and even then, when the upper support joint 11 approaches the back wall 3 again.
  • This movement is achieved in that the support bracket 5 is formed longer than the flashover tab 10.
  • the support holder 5 initially performs a rotation to the left until the flashover tab 10 and the support 4 are aligned. Thereafter, the support joint 11 kinks together with the rollover tab 10 and the support 4 in the manner of a toggle lever 1, wherein during this Einknickterrorism the support bracket 5 rotates about its hinge 9 back to the right.
  • the support bracket 5 is supported by the tongue 15 of the spring 14, which further causes the support 4 is held by the action of the spring 14 in the support position shown in Figure 3.
  • the folding of the support 4 can be achieved in that on the lower end of the support 4, a force in the direction of the rear wall 3 of the image holder 1 is applied. As a result, the support 4 rotates slightly about the hinge 8 until the support 4 and the rollover tab 10 are aligned. Thereafter, the rollover flap 10 deflects about the rollover joint 12, as the tongue 15 of the spring 14 causes rotation of the pillar holder 5 to the right, whereby the pillar joint 11 buckles.
  • the bias of the spring 14 is so large that it causes the rest of the movement of the support 4 and the four-bar support 6 in the rest position (vgl.Fig.4) automatically. By pressing on the joint edge 16 tongue 15 of the spring 14, the support 4 is also held in the rest position.
