It is 15% to 100% of coupling part 10 gauge W0 (with reference to Figure 13) that the gauge d of flexible member 2 is set to.When the gauge d of flexible member 2 less than coupling part 10 gauge W0 15% the time, just can't guarantee intensity and rigidity that flexible member 2 is enough, and also can't stably keep leaning on the final heeling condition of part 3.And, when the gauge d of flexible member 2 greater than coupling part 10 gauge W0 100% the time, the width dimensions of the hinge 1 that angle is adjustable will become excessive, and hinge may be restricted to the connection of sofa S.
The internal mechanism of the coupling part 10 of the hinge 1 that angle is adjustable can be hinge (although not illustrating in the drawings), has the ratchet mechanism that the engagement by pawl and the gear teeth forms, and can correct in protection scope of the present invention.
And, the hinge 1 that angle among the present invention is adjustable is provided with in the embodiment of Fig. 2 to 8 and in the embodiment of Fig. 9 to 13 is connected to the swing arm 47 (as shown in fig. 1) that leans on part 3, be fixed to firm banking part 40F, the linking arm 46 of 41F and 43F, and the connecting pin element 13 of linking arm 46 and 47.
Linking arm 46 has that its bottom is connected to the brace part 12 of connecting pin element 13 when not rotating, and the cover element 7 that is fixed to brace part 12 bottoms.That is to say that the brace part 12 of cover element 7 and bonding jumper is linked together by (ground combines) when not rotating.
The parallel H of bindiny mechanism is by consisting of by four pin 57,58,59 and 60 interconnected supports 48, swing sheet part 11 and braces 34 and 35.Such as Fig. 2 A, 2B, shown in 2C and the 2D, it is parallel with swing sheet part 11 that support 48 always keeps, and freely move forward and backward between bottom 45 1 sides that swing sheet part 11 and front end 44 1 sides.
And, the brace 34 that anti-folding mechanism 50 is provided with support 48, connection bracket 48 and swings sheet part 11 and 35 and be used for linking arm 37 that brace 34 is linked to each other with cover element 7.
The function that linking arm 37 has is: along with leaning on the swing of part 3 along vertical A, by namely increase the brachium L47 of swing arm 47 towards the direction traversing carriage 48 of front end 44 along front extreme direction P.
In the present invention, the brachium L47 of swing arm 47 refers to from the axis of connecting pin element 13 namely as the horizontal hunting axis L13 at the center distance (size) to support 48 tip portion 48A.
In order to further describe, linking arm 37 is made of the arc plate, its bottom is connected to thin disk with pin 38 cover element 7 to be freely swinging, and its front end with pin 39 be connected to connector 34 longitudinally centre position (at the nearside of connecting pin element 13) to freely swing.
To sell 38 and 39 according to arranging as mentioned above, linking arm 37 swings the arm 34 that consists of the parallel H of a bindiny mechanism part, and such as Fig. 2 A, among 2B and the 2C shown in the order like that or such as Fig. 4,5, the support 48 that consists of the parallel H of bindiny mechanism another part that makes like that in 6 and 7 shown in the order moves, increase gradually brachium L47, direction along arrow P among Fig. 1 moves the inside casing that is fixed to support 48 49 that leans on part 3, and strains (sharing) enclosure 28 to avoid producing the wrinkle 53 (with reference to Figure 17) that relax at the enclosure 52 when vertical A moves in dependence part 3.
As clear illustrating among Fig. 2 A to 2D or Fig. 4 to 7, cover element 7 is not have the thin disk of projection (bossing) in outer rim, and has the advantage that can not destroy the enclosure 28 inner surfaces (reverse side).And when observing along the direction that is parallel to horizontal hunting axis L13, linking arm 37 is always with disk cover element 7 with swing at least one overlaid in the sheet part 11 and swing along the direction of arrow A and B.That is to say, because the linking arm that the present invention relates to 37 has the structure of arc or L shaped (bending), and the size of arm 37 and link position ( pin 38 and 39 position) are set to and make arm 37 always with cover element 7 or swing sheet part 11 overlaids, so just can avoid the enclosure 28 to damage at inner surface (reverse side).
In order to increase the explanation that relates to another embodiment of the present invention, in Fig. 9 to 13 and Fig. 1, provide rotation moment of resistance M and lean on specifically disc spring 20 of flexible member 2 that part 3 swings along vertical A with restriction, be arranged on cover element 7 in be provided with on the relative face of the face of linking arm 37.As clear illustrating among Fig. 9, the densification that has reduced to be parallel to the gauge of pin element 13 axis directions and realized hinge.
And that some load that flexible member 2 usefulness resistance limits are subject to by the enclosure 28 with opposing along the swing of vertical A produces and act on tension force on the dependence part 3 that is in final heeling condition, remain on final heeling condition thereby will lean on part 3.
In the present invention, " stop swinging multistagely " and refer in the scope from final heeling condition to final upright state, set 7 grades or more multistage attitude fixed angles with uniform gradient, leaning on part 3 can swing to final upright state along vertical A, and the dependence part 3 that swings along vertical A is limited to avoid adipping B to return step by step.
Example with headrest 30 more clearly explains this point, from resting the head on the 30 final heeling conditions that are level in the scope of vertical attitude, set for example 16 grades of attitude fixed angles with even gradient with restriction headrest part 30 forward (along vertical A) swing and not step by step backward (along inclined direction B) return.And, come more clearly to explain this point with the example of toe board 31, in the adjustable hinge of angle, be vertical final heeling condition in the scope of horizontal attitude from toe board part 31, set for example 16 grades of attitude fixed angles with even gradient with restriction toe board part 31 upwards (along vertical A) swing and can be not step by step downwards (along inclined direction B) return.
In order further to carry out extra explanation, as shown in Figure 12 and 13, be provided with by the parallel H of bindiny mechanism be connected to the swing sheet part 11 that leans on part 3, the brace part 12 of the fixation side that is fixed to sofa S and non-rotatably fitting together be used to the connecting pin element 13 that is connected swing sheet part 11 and brace part 12 with brace part 12.The connecting pin element 13 that is assembled to brace part 12 connects swing sheet part 11 to freely swing around axis of oscillation L13.One end of connecting pin element 13 is formed into large diameter head 33, and is formed with the rectangular engaging groove 13a with axis of oscillation L13 at head 33.The other end of connecting pin element 13 has minor diameter, and fixing by riveted joint under the assembled state.
As shown in Fig. 3 and 9, when swinging the longitudinal 2 observation of sheet part 11, the structure of support 48 is inverted L-shapeds, be used for (coming by not shown screw, bolt or rivet) fixedly the connecting hole 36 of inside casing 49 be formed in the upper wall of support 48, as shown in Fig. 5 and 6, the U-shaped recess shape recess 29 of the pin 39 of packing into is formed on the upright wall part of support 48.To sell 39 when packing recess shape recess 29 into, hinge can be made very compactly (with reference to Fig. 2 A, 3 and 10).
Introduce now use (work) method of the adjustable hinge of angle above-mentioned among the present invention.
Fixation side from sofa S when at first, decorating in the production process of sofa S shown in Figure 1 or with the enclosure 28 arranges the enclosure 28 to leaning on part 3.In the case, being used for leaning on the adjustable hinge 1 of angle that part 3 is connected to sofa S fixation side limits by flexible member 2 usefulness rotation moment of resistance M and leans on the vertically swings (with reference to Figure 10 and 12) of A of part 3 edges.When leaning on part 3 and in use erect because the enclosure 28 is set to have suitable tension force when part 3 keeps final heeling condition leaning on, so even the enclosure 28 be relax also can reduce wrinkle.In the embodiment of Fig. 9 to 13 of the present invention, further be added with anti-folding mechanism 50, the enclosure 28 still can provide profile level and smooth and attractive in appearance and can not produce (usually as shown in Figure 17) wrinkle 53 when using with the dependence part 3 that is in upright state.
Then, swing to the mobile range upper limit along incline direction B namely among the sofa S of final heeling condition leaning on part 3, when having the people by taking one's seat take one's seat part 41 and back part 40 to be applied load, the part of taking one's seat 41 is born the enclosure 28 of the sagging load of human body or the enclosure 28 of back part 40 is understood by drop-down, and the tension force that acts on the dependence part 3 can strengthen to some extent.In the case, flexible member 2 usefulness rotation moment of resistance M limits as resistance and leans on part 3 along the swing of vertical A, and keeps natch final heeling condition.
Subsequently, to as shown in the 16C, the dependence part 3 that is in final heeling condition overcomes rotation moment of resistance M and holds up to A along vertical cube such as Fig. 1 and Figure 16 A.In Figure 16 A, toothed surfaces 4a and occlusion portion 11b engagement, and contact-making surface 4b contacts with wedge surface 5a.When occlusion portion 11b swung along vertical A as shown in Figure 16 B, the contact-making surface 4b of movable wedge element 4 became and separates with wedge surface 5a and form small gap g.When the vertical A in dependence part 3 edge as shown in Figure 16 C further swings, the lead-in chamfered 14 of movable wedge element 4 just contacts with the classification part 8 of the activity of wedged window section 5, discharge the engagement of toothed surfaces 4a and occlusion portion 11b, and toothed surfaces 4a accompanies by the strike note that is rebounded by interlock part 11b when passing through occlusion portion 11b.When the swing that leans on part 3 when desired location stops, movable wedge element 4 just is urged to occlusion portion 11b by spring steel wire 6, and toothed surfaces 4a is meshed with occlusion portion 11b.It is limited by the effect of wedge to lean on the along inclined direction swing of B of part 3, and leans on part 3 and be retained as required inclination angle.
And, opposite with accompanying drawing and foregoing, may need linking arm 46 is fixed to dependence part 3, and swing arm 47 is connected to firm banking part 40F, on the side of 41F and 43F (not shown in the accompanying drawing).That is to say that the support 48 of swing arm 47 is fixed to firm banking part 40F, the inside casing of 41F and 43F, and linking arm 46 is fixed to the inside casing 49 that leans on part 3.In the case, although horizontal hunting axis L13 approximate abreast or draw for arc shift to firm banking part 40F, 41F and 43F still can avoid producing lax wrinkle.And, advantageously can revise easily setting and structure that the inside casing 49 that leans on part 3 arrives the coupling part of linking arm 46.
As shown in Figure 15, swung predetermined amount when forming final upright state when leaning on part 3, push-in type projection 15 will contact as shown in Figure 16 D and the wedge element 4 of pushing activity.When leaning on part 3 and further swing along vertical A as Figure 16 E as shown in, the movable wedge element 4 that slides in the classification part 8 of the activity of wedged window section 5 just guides (leading) to reclaiming space 9 by lead-in chamfered 14.Reclaim space 9 when interior (corresponding to Fig. 8) when the wedge element 4 of activity is stored in, the engagement of toothed surfaces 4a and occlusion portion 11b namely is released, and along inclined direction the swing of B can freely be carried out.And as shown in Figure 16 F, when leaning on part 3 along inclined direction B swings to turn back to final heeling condition, push type projection 16 just contacts with movable wedge element 4 and with its release from reclaim space 9.As mentioned above, again form the state shown in Figure 16 A, toothed surfaces 4a and occlusion portion 11b mesh to limit the along inclined direction B swing of dependence part 3.
Although above article among the present invention the adjustable hinge 1 of angle along inclined direction B lean on part 3 and stop swinging and keep the situation at required inclination angle to be called " multistage " 7 grades or more multistage making, but progression can be 2 to 6 multistage, and one-level (single-stage) also is feasible.
As mentioned above, by the present invention, rotation moment of resistance M stops dependence part 3 to be stretched by the enclosure 28 among the sofa S and swings along vertical A, and when being in when using sofa S under the final heeling condition leaning on part 3, leaning on part 3 can unexpectedly not erect and stably keep attitude, reason is in the adjustable hinge of the angle of the sofa S that tiltable dependence part 3 is housed, can swing along vertical A so that lean on part 3, and along inclined direction B stops swinging the inclination angle that keeps required multistagely, be provided with flexible member 2, provide rotation moment of resistance M and swing with the restriction dependence part vertical A in 3 edges.And the enclosure 28 can be set to have suitable tension force to keep leaning on the attitude that part 3 tilts to final heeling condition, and the enclosure 28 can not relax when leaning on part 3 setting, and sofa can obtain good looking appearance.
In the present invention, as mentioned above, sharing the enclosure 28 generations lax wrinkle to limit along with leaning on part 3 along the swing of vertical A because in the adjustable hinge of angle, be provided with anti-folding mechanism 50, so tension force is along with the hinge of lateral attitude is holded up and acted on the enclosure 28 along vertical A, can not produce lax wrinkle, kept level and smooth surface attractive in appearance, and the large volume that the furniture that is improved is particularly crossed with decorative leather and comfort level and the aesthetic feeling of luxurious furniture, the hinge that angle is adjustable is used for having the part 3 of leaning on and firm banking part 40F, 41F, the furniture of 43F, leaning on part 3 can tilt and covered by the shared enclosure 28 around horizontal hunting axis L13, and make lean on part 3 can be in the vertical A swing along inclined direction B with single-stage or multistage (a plurality of stage) thus stop swinging and keep required inclination angle.
And, number of components as the adjustable hinge of angle is less, hinge size vertically is less, and hinge overall compact, have simple in structure, lightweight and economic reason and be to be provided with the swing arm 47 that is connected to dependence part 3, be fixed to firm banking part 40F, 41F, the linking arm 46 of 43F, the connecting pin element 13 of connection swing arm 47 and linking arm 46.Swing arm 47 is provided with the swing sheet part 11 that its bottom 45 is connected to pin element 13, the support 48 that the inside casing 49 of dependence part 3 is fixed thereon, and two braces 34 that consist of the parallel H of bindiny mechanism by connection bracket 48 and swing sheet part 11,35, linking arm 46 has the brace part 12 that its bottom is connected to pin element 13, and the cover element 7 that is fixed to brace part 12 bottoms, and anti-folding mechanism 50 is provided with support 48, consist of two braces 34 of the parallel H of bindiny mechanism by connection bracket 48 and swing sheet part 11,35, and with brace 34, one of 35 linking arms 37 that link to each other with cover element 7, thus along with lean on part 3 along the swing of vertical A by increase the brachium L47 of swing arm 47 along front extreme direction P traversing carriage 48.Particularly, although very compact, the stroke of support 48 (along the amount of movement of front extreme direction P) still can be made as enough large.
Because cover element 7 is thin disks, and structure, size and the link position at linking arm 37 two ends are set to along when observing corresponding to the parallel direction of the horizontal hunting axis L13 of pin element 13 axis, linking arm 37 is always with disk cover element 7 with swing at least one overlaid in the sheet part 11, so just can not produce local small lugs (small embossment) at the enclosure 28, can obtain for example sofa of comfortable furniture, and the enclosure 28 is avoided damaged in reverse side.And this structure can also obtain outstanding outside aesthetic feeling.
