Definitions

  • the invention relates to a clamping frame for the production of rectangular frames, in particular picture frames, with a first frame part consisting of two legs arranged at right angles and firmly connected to one another and two further frame legs arranged at right angles to one another and displaceably guided relative to the first frame part to form a closed rectangular tension frame , wherein the two further frame legs protrude outward beyond the legs of the first frame part and furthermore, parallel to the legs of the first frame part, are provided on the outside of the tie rods which engage the projecting sections of the two further frame legs.
  • a clamping frame of this type is known for example from DK-PS 36 881.
  • a first frame part consisting of two legs arranged at right angles to one another and two further frame legs which are loosely connected to one another and displaceable relative to the first frame part and form a second frame part, to form a closed stenter frame, the two further, loosely supported frame legs can be tightened separately from each other against the first frame part by means of a pull rod in the form of a screw spindle.
  • the legs of the second frame part are guided in longitudinal slots of the first frame part and the screw spindles are mounted on the outside of the legs of the first frame part in guide pieces rigidly connected to the first frame part.
  • two further screw spindles are provided which run parallel to the legs of the second frame part on the outside thereof, in order to tighten the projecting ends of the loose legs of the second frame part relative to the projecting ends of the fixed legs of the first frame part can.
  • a relatively complex chain drive ensures that the additional screw spindles are rotated together with the first screw spindles, so that warping of the clamping frame is avoided.
  • a device for compressing wooden frames which has a base plate on which a first frame part consisting of two frame legs running at right angles to one another is fastened. At least one eccentric press is provided on each of the sides opposite the fixed frame legs of the clamping frame and acts directly on the corresponding sides of the frame to be clamped.
  • This device has the disadvantage that it cannot be used for clamping frames of different sizes, since the position of the eccentric presses would have to be changed each time.
  • a clamping frame which consists essentially of four assigned to the corners of the clamping frame right-angled elbows and four threaded rods, each anchored in one leg of an elbow and through a hole in the other leg of the other elbow stretch loosely, with the help of a nut the other elbow can be tightened against the one elbow.
  • This clamping frame in turn allows the clamping of picture frames of different sizes, but has the disadvantage that it can be easily warped when tightening, since the angular pieces only have to be spatially aligned when tightening, which has to take place alternately at all four corners of the frame fixed to each other.
  • the invention is based on the object of designing a clamping frame of the type mentioned at the outset in such a way that the clamping frame can be clamped without warping with little technical effort and can be adjusted to different picture frame sizes at any time without major circumstances.
  • the two further frame legs are firmly connected to one another to form a second frame part, in that the tie rods intersect at the corner of the first frame part and in that on the portions of the legs of the second frame part protruding beyond the legs of the first frame part and the tie rods that can be attached and are supported on the outside of the legs of the first frame part are provided for clamping the second frame part on the first frame part.
  • the clamping frame is composed of two fixed or rigid frame parts which are displaceable relative to one another, which can be fixed against each other with the help of clamps.
  • the right angle at the corners of the clamping frame, in particular at the diagonally opposite corners, which are formed by the two fixed frame parts, can be exactly maintained when tightening, so that in connection with the use of clamping clamps - which moreover is quick Allow adjustment of the frame size - a distortion-free clamping of the clamping frame results.
  • a rigid frame part 10 consisting of two legs 10a, 10b arranged at right angles to one another is fastened on a base plate 12 in such a way that the legs 10a and 10b, which are L-shaped in profile, engage under the base plate 12.
  • the legs 10a and 10b of the frame part 10 each have a longitudinal slot 14 which are penetrated by the legs 16a, 16b of a second rigid frame part 16 which run at right angles to one another.
  • the second frame part 16 forms with the first frame part 10 a rectangular clamping frame, the size of which can be changed by moving the second frame part 16 relative to the first frame part 10.
  • tie rod 18 running parallel to the leg, which is guided in U-shaped guide pieces 20 and engages the respectively associated legs 16a, 16b of the second frame part.
  • the connection between tie rod 18 and leg 16a or 16b is such that leg 16a or 16b can be displaced in its longitudinal direction with respect to the tie rod.
  • the tie rods are oriented such that they intersect at the corner of the first frame part 10.
  • Angle pieces 20 ' are assigned to the corners of the clamping frame consisting of the frame parts 10 and 16, the angle pieces, the legs of which extend over a relatively short section of the legs 10a, 10b, 16a, 16b, at the corners of the frame parts 10 and 16, respectively are rigidly connected to these, while the other angle pieces 20 ′′, which are assigned to the corners formed by the intersections of the legs 10a, 16a and 10b, 16b, are displaceably guided in the longitudinal slots 14 and loosely on the legs 16a, 16b of the second Bearing frame part 16.
  • the latter angle pieces 20 "contribute substantially to the right-angled alignment of the tenter frame.
  • Clamping clamps 22 are arranged on the outwardly projecting sections of the legs 16a, 16b of the second frame part 16 and the pull rod 18, which are supported on the outside of the legs 10a, 10b of the first frame part 10. With the aid of the clamping clamps 22, the second frame part 16 can now be tightened relative to the first frame part 10 in such a way that the frame is pressed together from all sides, in order to clamp a frame 24 shown in broken lines in the figure.
  • the use of the tie rods 18 ensures that the tensile forces, which are represented by arrows in the figure, can be distributed in the sense of a balanced load.
