  • the wrinkles 53 tend to be generated especially in voluminous and luxurious furniture upholstered with leather, using comfortableness (seating comfortableness) is reduced and beauty of the furniture is greatly damaged by the generation of the wrinkles 53.
  • an angle-adjustable hinge of the present invention is used for furniture such as a sofa S provided with reclinable (inclinable) rest portions 3 and a chair (not shown in Figures).
  • Plural angle-adjustable hinges 1 are used for the sofa S.
  • a seat portion 41 and a backrest portion (back portion) 40 are held by left and right leg portions 42.
  • the backrest portion (back portion) 40 has a rest portion 3 inclinable around a horizontal oscillation axis L13, and the rest portion 3 is specifically a headrest portion 30. That is to say, the backrest portion 40 is composed of a fixation base portion 40F on a lower position and the inclinable headrest portion 30 on an upper position, and the headrest portion 30 (rest portion 3) is covered by a common cover 28 with the fixation base portion 40F.

  • the angle-adjustable hinge 1 shown in Figure 1 corresponds to the hinge shown in Figures 9 through 13 , and the hinge shown in Figures 3 through 7 can be disposed on the same positions in Figure 1 when desired.
  • the greatest characteristic of the angle-adjustable hinge 1 relating to the present invention is that a wrinkle prevention mechanism 50 to restrict lax wrinkles on the common cover 28 along with the oscillation in the standing direction A of the rest portion 3 is provided.
  • the wrinkle prevention mechanism 50 is simplified in Figure 1 , and only a bracket 48, to which an inner frame 49 (shown with dotted lines) is fixed, is drawn (the mechanism 50 will be described later in detail with Figures 2 through 11 ).
  • Figure 12 and Figure 13 are drawn omitting the wrinkle prevention mechanism 50.
  • the angle-adjustable hinge 1 of the present invention is provided with a pair of parallel wall portions 12a formed circular around the oscillation axis L13 as the center, 4 wedge-shaped window portions 5 disposed on each of the wall portions 12a in rotation symmetry of which axis of symmetry is the oscillation axis L13, a pair of floating wedge members 4, movable within the wedge-shaped window portion 5, disposed on positions rotation-symmetric for 180° of which axis of symmetry is the oscillation axis L13, and each of which has a toothed face 4a on one side, a pair of arc-shaped gear portions 11b disposed between the wall portions 12a and formed around the oscillation axis L13 as the center as to have outer teeth to engage with the toothed face 4a, and spring wires 6 always elastically pushing the floating wedge members 4 to the pair of arc-shaped gear portions 11b

  • Each wedge face 5a is formed around a guiding axis Y as the center eccentric with the oscillation axis L13 and disposed rotation symmetric for 90° of which axis of symmetry is the oscillation axis L13. That is to say, as approaching in clockwise direction in Figure 14 , the gap between the wedge face 5a and the gear portion 11b gradually becomes small (diminishes).
  • a floating staged portion 8 is formed protruding from the arc face 5b on the inner side to guide the floating wedge member 4.
  • a retreat space 9 for storing the floating wedge member 4 not engaging with the gear portion 11b (in engagement released state) is provided.

  • the spring wire 6 is cut into a predetermined length and formed straight. An end of the spring wire 6 is straight and another end is bent into a hook or a circle to fit to a supporting portion 17. The spring wire 6 is touching the contact face 4b and elastically deformed into arc shape, and always elastically giving resilient force to the floating wedge member 4.
  • the contact face 4b is formed as to be guided to the wedge face 5a to dispose the floating wedge member 4 between the gear portion 11b and the wedge face 5a when the gear portion 11b oscillates and the floating wedge member 4 is moved by engagement of the toothed face 4a with the gear portion 11b. That is to say, the floating wedge member 4 restricts the toothed face 4a to engage with the gear portion 11b, the contact face 4b to contact the wedge face 5a, and the gear portion 11b (the oscillation piece portion 11) to oscillate in one direction (the inclining direction B).
