Definitions

  • This invention relates to an angle-adjustable hinge used for sofas.
  • the inventor of the present invention proposed an angle-adjustable hinge, making oscillation in a standing direction of a reclining part possible, stops oscillation in inclining direction to hold the reclining part with predetermined multi-stage inclination angles as disclosed in Japanese patent No. 4296223 .
  • the conventional angle-adjustable hinge has a construction in which the oscillation in the inclining direction of the headrest, etc. is restricted with multi stage to hold the posture of the reclining part. So the headrest, etc. oscillates very lightly with click sound in the opposite standing direction. Therefore, when the cover of the seat, receiving the load of a person sitting on the sofa, is sagged and the cover of the backrest is pulled downward, the headrest, etc. is pulled in the standing direction by the tension of the cover as to un intentionally stand, and desired final inclination state can't be maintained.
  • the reclining part is oscillated in the standing direction when the cover is pulled, and the work can't be conducted with the final inclination state maintained. So it is quite difficult to upholster with sufficiently large tension as not to generate creases on the cover.
  • an angle-adjustable hinge of the present invention is used for a sofa S provided with reclinable rest portions 3.
  • Plural angle-adjustable hinges 1 are attached to the sofa S to attach the plural rest portions 3 to a fixation side of the sofa 3 as to be freely oscillated.
  • the sofa S shown in Figure 1 and Figure 5 is supported by leg portions 42 and having a seat portion 41 and a backrest portion 40 fixed to the leg portions 42.
  • headrest portions 30 are attached to an upper end of the backrest portion 40
  • footrest portions 31 are attached to a front end of the seat portion 41
  • armrest portions 32 are attached to the both sides of the seat portion 41 with the angle-adjustable hinges 1.
  • the sofa S is upholstered with continuous cover E from fixation side to the rest portions 3.
  • the cover E is upholstered as to be tensed with predetermined tension with small number of creases generated when the rest portions 3 stand in the final inclination state in which the rest portions 3 are oscillated in an inclining direction B to the limit of movement range.
  • the angle-adjustable hinge 1 is constructed as to make the rest portion 3 oscillatable in a standing direction A and stop oscillation in the inclining direction B with multi stage to hold a desired inclination angle.
  • the angle-adjustable hinge 1 is provided with an elastic member 2 giving rotation resistance moment M to restrict the oscillation of the rest portion 3 in the standing direction A.
  • the elastic member 2 as described later, restricts the oscillation in the standing direction A with resistant force as to hold the rest portion 3 in the final inclination state resisting against the tension generated by some load received by the cover E of the sofa S and working on the rest portion 3 in the final inclination state.
  • stop oscillation with multi stage means that 10 or more stages of posture holding angles are set with uniform pitch within a range from the final inclination state to a final standing state toward which the rest portion 3 is oscillated in the standing direction A, and the rest portion 3 oscillated in the standing direction A is restricted gradationally as not to return toward the inclining direction B.
  • the headrest portion 30 in the angle-adjustable hinge, used for the sofa S provided with the headrest portion 30 attached to the upper end of the backrest portion 40 as to be freely oscillated back and forth in the standing direction A and the inclining direction B and having the cover E upholstered continuously from the backrest portion 40 to the headrest portion 30 as to be tensed with predetermined tension in the final inclination state of the headrest portion 30, the headrest portion 30 is oscillatable in the standing direction A, and the oscillation in the inclining direction B is stopped with multi stage to hold the desired inclination angle, the elastic member 2 is provided to give rotation resistance moment M as resistant force to a part of the headrest portion 30 to restrict the oscillation of the headrest portion 30 in the standing direction A and keep the headrest portion 30 in the final inclination state when the cover E of the backrest portion 40 in tension is pulled downward by the load of a person sitting on the sofa S.
  • posture holding angles of, for example, 16 stages with uniform pitch are set to restrict the headrest portion 30 oscillated forward (in the standing direction A) as not to return backward (in the inclining direction B) gradationally.
  • the footrest 31 in the angle-adjustable hinge, used for the sofa S provided with the footrest portion 31 attached to the upper end of the seat portion 41 as to be freely oscillated back and forth in the standing direction A and the inclining direction B and having the cover E upholstered continuously from the seat portion 41 to the footrest portion 31 as to be tensed with predetermined tension in the final inclination state of the footrest portion 31, the footrest portion 31 is oscillatable in the standing direction A, and the oscillation in the inclining direction B is stopped with multi stage to hold the desired inclination angle, the elastic member 2 is provided to give rotation resistance moment M as resistant force to a part of the footrest portion 31 to restrict the oscillation of the footrest portion 31 in the standing direction A and keep the footrest portion 31 in the final inclination state when the cover E of the seat portion 41 in tension is sagged by the load of a person sitting on the sofa a S.
  • posture holding angles of, for example, 16 stages with uniform pitch are set to restrict the footrest portion 31 oscillated upward (in the standing direction A) as not to return downward (in the inclining direction B) gradationally.
  • an oscillation piece portion 11 attached to the rest portion 3, an attachment piece portion 12 fixed to a fixation side of the sofa S, and a connecting pin member 13 assembled with the attachment piece portion 12 unrotationally to connect the oscillation piece portion 11 and the attachment piece portion 12, are provided.
  • An end of the connecting pin member 13 is made into a head 33 of large diameter, and a hitching groove 13a at right angles with the oscillation axis X is formed on the head 33.
  • Another end of the connecting pin member 13 is having small diameter, and stopped by caulking in assembled state.
  • the elastic member 2 is a spiral spring 20 composed of a spiral metal spring of which outer end portion 22 bent in L-shape is hitched to a hitching portion 11a protruding from a position near a base end portion of the oscillation piece portion 11, and of which inner end portion 21 bent approximately into right angle is hitched to the hitching groove 13a of the connecting pin member 13.
  • the spiral spring 20 is elastically giving resistant force as the rotation resistance moment M to the oscillation piece portion 11 as to restrict the oscillation in the standing direction A of the oscillation piece portion 11 as the rest portion 3 does not stand even if the cover E in tension receives load further in the rest portion 3 in the final inclination state.
  • the angle-adjustable hinge 1 is provided with a pair of parallel wall portions 12a formed circular around the oscillation axis X 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 X, 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 X, 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 X 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.
  • the wall portions 12a are extended from the attachment piece portion 12, formed as facing plates between which the gear portions 11b can be inserted, and penetrated by a center hole concentric with the oscillation axis X.
  • an inner side near the oscillation axis X is an arc face 5b, and an arc-shaped wedge face 5a is formed on an outer side.
  • Each wedge face 5a is formed around a guiding axis Y as the center eccentric with the oscillation axis X and disposed rotation symmetric for 90 ° of which axis of symmetry is the oscillation axis X. That is to say, as approaching in clockwise direction in Figure 6 , 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.
  • Each of the floating wedge members 4 is respectively inserted to each of the wedge-shaped window portion 5 disposed on the positions in rotation symmetry for 180° .
  • the floating wedge member 4 is formed slightly larger than the gap dimension between the wall portions 12a, and protruding both end side portions from outer faces of the wall portions 12a when inserted to the wedge-shaped window portion 5.
  • One face side of the floating wedge member 4 is the toothed face 4a, and an arc-shaped contact face 4b is formed on another face side to contact the wedge face 5a.
  • the floating wedge member 4 has a guiding sloped face 14 to contact the floating staged portion 8 and guide itself toward a direction parting from the gear portion 11b.
  • the guiding sloped face 14 is formed on a rear edge portion of the toothed face 4a.
  • the pair of gear portions 11b is attached as to oscillate around the oscillation axis X between the wall portions 12a.
  • the gear portions 11b are formed as outer teeth on escape window portions 18, formed through the oscillation piece portion 11 to insert the floating wedge member 4, on positions in rotation symmetry for 180° of which axis of symmetry is the oscillation axis X.
  • the configuration of the gear portion 11b hardly generates stress concentration on the base end portion of the oscillation piece portion 11.
  • a push-in protrusion 15 to push the floating wedge member 4 to the retreat space 9 is formed on an end portion side (end portion side of engagement), and a push-out protrusion 16 to push the floating wedge member 4 out of the retreat space 9 on another end portion side (initial portion side of engagement).
  • 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).
  • the wall portions 12a are embraced by the thin circular (disc-shaped) cover members 7 from the oscillation axis X direction.
  • the connecting pin member 13 concentrically connects the wall portions 12a, the gear portions 11b, and the cover members 7. That is to say, the connecting portion 10 is composed that the wall portions 12a, the wedge-shaped window portions 5, the floating wedge members 4, the gear portions 11b, and the spring wires 6 are assembled and stored between the cover members 7.
  • a thickness dimension d of the elastic member 2 is set to be 15% to 100% of a thickness dimension W 0 of the connecting portion 10 (refer to Figure 3 ).
  • the thickness dimension d of the elastic member 2 is smaller than 15% of the thickness dimension W 0 of the connecting portion 10, sufficient strength and rigidity of the elastic member 2 can't be secured and the final inclination state of the rest portions 3 can't be stably kept.
  • the thickness dimension d of the elastic member 2 is larger than 100% of the thickness dimension W 0 of the connecting portion 10, width dimension of the angle-adjustable hinge 1 becomes excessively large, and attachment of the hinge to the sofa S may be restricted.
  • the angle-adjustable hinge 1 may be a hinge (although not shown in Figures) having a ratchet mechanism by engagement of a claw and gear teeth, and may be modified within the scope of the present invention.
  • the cover E is set from the fixed side of the sofa S to the rest portion 3 in production process of the sofa S shown in Figure 1 and Figure 5 or upholstering of the cover E.
  • the angle-adjustable hinge 1 to attach the rest portion 3 to the fixed side of the sofa S restricts the oscillation of the rest portion 3 in the standing direction A with the rotation resistance moment M by the elastic member 2.
  • creases are hardly generated even if the cover E slacks because the cover E is set with appropriate tension while the rest portion 3 keeps the final inclination state.
  • the cover E of the seat portion 41 receiving the load of the person sags or the cover E of the backrest portion 40 is pulled downward, and the tension working on the rest portion 3 is increased.
  • the elastic member 2 restricts the oscillation of the rest portion 3 in the standing direction A with the rotation resistance moment M as the resistant force, and certainly keeps the final inclination state.
  • the elastic member 2 may be a torsion coil spring 23 concentrically wound around the oscillation axis X.
  • the torsion coil spring 23 is wound around the head 33 of the connecting pin member 13.
  • An end portion 24 of the torsion coil spring 23 bent L-shaped is hitched to the hitching portion 11a of the oscillation piece portion 11, and another end portion 25 of the torsion coil spring 23 bent approximately J-shaped is hitched to a protruding portion 19 going through the cover member 7 and fixed to the attachment piece portion 12.
  • the torsion coil spring 23 is elastically giving resistant force as the rotation resistance moment M to the oscillation piece portion 11 as to restrict the oscillation in the standing direction A of the oscillation piece portion 11 as the rest portion 3 does not stand even if the cover E in tension receives load further in the rest portion 3 in the final inclination state.
  • the connecting pin member 13, not necessarily unrotational against the attachment piece potion 12 may simply connects the oscillation piece portion 11 and the attachment piece portion 12.
  • the rotation resistance moment M prevents the rest portion 3 from being pulled by the cover E of the sofa S and oscillated in the standing direction A, and the rest portion 3 does not unintentionally stand and the posture is stably kept when the sofa S is used with the rest portion 3 in the final inclination state because in an angle-adjustable hinge, used for the sofa S provided with the reclinable rest portion 3, making oscillation of the rest portion 3 in the standing direction A possible, and stopping oscillation in the inclining direction B with multi stage to keep a desired inclination angle, the elastic member 2, giving the rotation resistance moment M to restrict the oscillation of the rest portion 3 in the standing direction A, is provided.
  • the cover E can be set with appropriate tension keeping the posture in which the rest portion 3 is inclined to the final inclination state, the cover E does not unnecessarily slack when the rest portion 3 is upright, and the sofa can be made fine in appearance.
  • the spiral spring 20 can be attached with simple construction without increase of parts, and the rotation resistance moment M is certainly given to the oscillation piece portion 11 because the oscillation piece portion 11 attached to the rest portion 3, the attachment piece portion 12 fixed to the fixation side of the sofa S, and the connecting pin member 13 unrotationally assembled with the attachment piece portion 12 and connecting the oscillation piece portion 11 and the attachment piece portion 12, are provided, and the elastic member 2 is the spiral spring 20, the outer end portion 22 of the spiral spring 20 is hitched to a part of the oscillation piece portion 11, and the inner end portion 21 of the spiral spring 20 is hitched to the connecting pin member 13. Further, the hinge is made compact and easy to attach within the sofa S.

Further, the hinge is made compact and easy to attach within the sofa S.
  • the force (load) working on the gear portions 11b and the floating wedge members 4 can be uniformly dispersed, and the whole hinge can be made small and thin because the pair of parallel wall portions 12a formed circular of which center is the oscillation axis X of the oscillation piece portion 11, the wedge-shaped window portions 5 of even number disposed on positions in rotation symmetry of which axis of symmetry is the oscillation axis X on each of the wall portions 12a, the pair of floating wedge members 4 movable within the wedge-shaped window portions 5, disposed on positions in rotation symmetry for 180° of which axis of symmetry is the oscillation axis X, and having the toothed face 4a on one side, the pair of arc-shaped gear portions 11b disposed between the wall portions 12a, and formed around the oscillation axis X as the center into outer teeth to engage with the toothed face 4a, and the spring wires 6 always elastically pushing the floating wedge members 4 to the gear portions 11b, are provided.
