Definitions
- This invention relates to an angle-adjustable hinge.
- EP 2 767 188 A1 An earlier patent application, which was published after the present priority date, is EP 2 767 188 A1 . This document refers to an angle-adjustable hinge and a sofa.
- a further document is US 2005/0046260 A1 referring to an angle-adjustable hinge provided with a first arm having a case portion and a second arm connected to the first arm with the case portion so as to oscillate around a first axis and having a gear portion.
- the angle-adjustable hinge is also provided with a wedge-shaped window portion formed on the case portion of the first arm and a floating wedge member, disposed so as to move within the wedge-shaped window portion having one face side as a toothed face to engage with the gear portion and another face side as a contact face so as to contact a wedge face on an outer side of the wedge-shaped window portion.
- an angle-adjustable hinge Z is used to recline a rest portion 50 such as a headrest 48 and an armrest 49.
- the sofa S has a construction in which its posture is kept with a desired inclination angle by restriction of oscillation of the rest portion 50 in a direction B by the angle-adjustable hinge Z, and the rest portion 50 oscillates in another direction A with click sound.
- the inventor of the present invention has proposed many angle-adjustable hinges to keep the inclination angle of the rest portion 50 with multi stage (refer to Japanese patent No. 4418519 , for example).
- a first member and a second member are pivoted to relatively oscillate, and oscillation (in one direction) of the first member and the second member is restricted by wedge function of a floating wedge member.
- the wedge function of the floating wedge member is nullified by setting the first member and the second member to a predetermined lock-releasing position, and free oscillation (in one direction) of the first member and the second member is made possible.
- the wedge function of the floating wedge member is once nullified, the wedge function (locked state) can't be recovered until the first member and the second member are set to a predetermined lock recovery position. That is to say, there is a disadvantage that the posture of the first member and the second member can't be kept with the locked state on a middle position on way of the oscillation from the lock-releasing position to the lock recovery position.
- the sofa S shown in figure 13 and figure 14 is constructed as that free oscillation is made possible when the headrest 48 or the armrest 49 is raised to a vertical posture (lock-releasing position), then, the lock is recovered when the headrest 48 or the armrest 49 is inclined in an arrow B direction to a horizontal posture (lock recovery position). With the recovery of the locked state, the inclined posture can be held with a desired inclination angle when the headrest 48 or the armrest 49 is gradually raised to an arrow A direction.
- the lock may not be recovered because the armrest 49 may interfere (contact) with a base portion 45 before reaching for the lock recovery position. Similarly, the lock may not be recovered because the headrest 48 may interfere (contact) with an upper end face of a back portion 46. And, it is also a problem that the locked state of the armrest 49 (the headrest 48) may not be recovered in case that obstacles are put on the base portion 45 (the upper end face of the back portion 46).

Description
- This invention relates to an angle-adjustable hinge.
- An earlier patent application, which was published after the present priority date, is
EP 2 767 188 A1 - A further document is
US 2005/0046260 A1 referring to an angle-adjustable hinge provided with a first arm having a case portion and a second arm connected to the first arm with the case portion so as to oscillate around a first axis and having a gear portion. The angle-adjustable hinge is also provided with a wedge-shaped window portion formed on the case portion of the first arm and a floating wedge member, disposed so as to move within the wedge-shaped window portion having one face side as a toothed face to engage with the gear portion and another face side as a contact face so as to contact a wedge face on an outer side of the wedge-shaped window portion. - In a sofa S as shown in
figure 13 andfigure 14 , an angle-adjustable hinge Z is used to recline arest portion 50 such as aheadrest 48 and anarmrest 49. The sofa S has a construction in which its posture is kept with a desired inclination angle by restriction of oscillation of therest portion 50 in a direction B by the angle-adjustable hinge Z, and therest portion 50 oscillates in another direction A with click sound. - The inventor of the present invention has proposed many angle-adjustable hinges to keep the inclination angle of the
rest portion 50 with multi stage (refer to Japanese patent No.4418519 - In the angle-adjustable hinge disclosed by Japanese patent No.

member and the second member are set to a predetermined lock recovery position. That is to say, there is a disadvantage that the posture of the first member and the second member can't be kept with the locked state on a middle position on way of the oscillation from the lock-releasing position to the lock recovery position. - Conventionally, the sofa S shown in
figure 13 andfigure 14 is constructed as that free oscillation is made possible when theheadrest 48 or thearmrest 49 is raised to a vertical posture (lock-releasing position), then, the lock is recovered when theheadrest 48 or thearmrest 49 is inclined in an arrow B direction to a horizontal posture (lock recovery position). With the recovery of the locked state, the inclined posture can be held with a desired inclination angle when theheadrest 48 or thearmrest 49 is gradually raised to an arrow A direction. - However, when excessive load (in the arrow B direction to restrict the oscillation) is on the
headrest 48 or thearmrest 49, loosening is generated on an attached portion of the angle-adjustable hinge Z and a fixation member of the sofa S, or, the angle-adjustable hinge Z itself is plastically deformed, the lock may not be recovered because thearmrest 49 may interfere (contact) with abase portion 45 before reaching for the lock recovery position. Similarly, the lock may not be recovered because theheadrest 48 may interfere (contact) with an upper end face of aback portion 46. And, it is also a problem that the locked state of the armrest 49 (the headrest 48) may not be recovered in case that obstacles are put on the base portion 45 (the upper end face of the back portion 46). - Therefore, it is an object of the present invention to provide an angle-adjustable hinge with which the locked state is easily recovered on a random position on way of free oscillation of the first member and the second member from the lock-releasing position, and angle adjustment is conducted on a desired middle position to keep the posture of the angle-adjustable hinge.

first member 1 is provided with a pair of facingplate portions 13 to hold thedisc body 16 and anattachment portion 17 to be fixed to thearmrest portion 49 or theheadrest portion 48. A circular supportinghole 21 and a (wedge-shaped)window portion 5 for forming a wedge-shaped space to hold the floatingwedge member 6 are formed through each of the facingplate portions 13. Further, a hitchingsmall protrusion 33 and apivot shaft portion 27 of small diameter are protruding from an outer side of the facingplate portion 13. The (wedge-shaped)window portion 5 has thewedge face 8 of arc shape to form aretreat space 25 to store thefloating wedge member 6 as to part from thegear portion 4. According to the invention a circularlow protrusions 24, insertable to the circular supportingholes 21, are protruding from left and right sides of thedisc body 16. Thegear portion 4 is formed for a range of 1/3 to 1/4 of the peripheral edge of the disc body 16 (a range of center angle of 90° to 120°), and a protruding portion (timing protrusion) 28 is formed on 2 points, namely, a beginning portion and an end portion of thegear portion 4. Thedisc body 16 is held as to freely rotate by the pair of facingplate portions 13 with the circularlow protrusions 24 inserted to the circular supportingholes 21, and the facingplate portions 13 are disposed mutually parallel and fixed (riveted) to theattachment portion 17 withrivets 42.. - The
second member 2 has anattachment portion 18 to be fixed to thesofa fixation portion 45 or theback portion 46, and thenon-circular shaft portion 20 is protruding from one end of theattachment portion 18. Theshaft portion 20 has afemale screw hole 44. Pluralsmall holes 29 for bolts and screws are formed on theattachment portions - The floating
wedge member 6 is held within the wedge-shaped space formed with the pair of facing plate portions 13 (the window portions 5) and thegear portion 4, and both side end portions are protruding (left and right) from thewindow portions 5. Preferably, 13 to 20 gear teeth are formed on thetoothed face gear portion 4 of thedisc body 16. Therefore, the number of stages of angle adjustment can be more than 40. A spring (elastic)member 26 to elastically push the floatingwedge member 6 to thegear portion 4 is provided on thecontact face 9 side (theattachment portion 17 side) of the floatingwedge member 6. - As shown in
figures 6A and 6B , andfigures 12A and 12B , in an engaged state in which thecontact face 9 of the floatingwedge member 6 and thetoothed face 7 and thegear portion 4 engage, the relative oscillation of thefirst member 1 and thesecond member 2 in a direction B is restricted (stopped). And, as shown infigures 9A and 9B , thefirst member 1 and thesecond member 2 are relatively oscillated in another direction A to set a lock-releasing position P0, and the floatingwedge member 6 is moved and parted from thegear portion 4 to make a retreat state in which the engagement of thegear portion 4 and thetoothed face 7 is released thereby. Under the retreat state shown infigures 10A and 10B , thefirst member 1 and thesecond member 2 can be relatively oscillated in the direction B. In the present invention, it is called "free oscillation (M1)" that the lock (restriction on oscillation) of thefirst member 1 and thesecond member 2 is released and thefirst member 1 and the second member 2 (relatively) oscillate in the direction B. - The angle-adjustable hinge of the present invention is provided with a recovery means 10 which recovers the floating
wedge member 6 in the retreat state to the engaged state with thegear portion 4 by the return action M2 of the predetermined small angle θ in the direction A during the free oscillation M1 in which thefirst member 1 and thesecond member 2 in the lock-releasing position P0 are relatively oscillated in the direction B as shown infigures 11A and 11B . - The recovery means 10 is provided with a
ring member 12 which rotates against the facingplate portion 13 within a range of the predetermined small angle θ, an oscillatingmember 11, of which oneend 11a is interlockingly connected to thering member 12 and freely oscillating within a predetermined angle range with a middle portion as a fulcrum and anotherend 11b is disposed as to be pressed to the floatingwedge member 6 in the retreat state, and a press-fitfrictional member 15, having a non-circularfitting hole 19 fit to theshaft portion 20 to rotate unitedly with theshaft portion 20, and having anelastic portion 14 elastically pushing thering member 12 in an axial inner direction and sliding on thering member 12. - Under the retreat state shown in
figures 10A and 10B , the floatingwedge member 6 keeps the retreat state (kept on a first position V1 on which theend 11b of the oscillatingmember 11 does not press the floating wedge member 6) during the free oscillation M1 of thefirst member 1 and thesecond member 2 in the direction B. By the return action M2 in the direction A as shown infigures 11A and 11B , thering member 12 is rotated by frictional force with theelastic portion 14 for the predetermined small angle θ, and the oscillating member 11 (moving to a second position V2 on which theend 11b presses the floating wedge member 6) moves the floating wedge member 6 (as to push out of the retreat space 25) to make thegear portion 4 and thetoothed face 7 engaged. - As shown in
figure 1 , thering member 12 is formed as a ring having acircular hole portion 22 to which theshaft portion 20 is inserted, and, a hitchingconcave portion 34 corresponding to thesmall protrusion 33 and an arc-shaped notchedportion 32 are formed on the peripheral edge portion. Thering member 12 is hitching thesmall protrusion 33 to the hitchingconcave portion 34 movably (with backlash), and rotatable within the range of the predetermined small angle θ around the oscillation axis C as the center. - The oscillating
member 11 is composed of metal (or resin) of high rigidity formed approximately V-shape, and theend 11a (formed into a short cylindrical column) is fit to the arc-shaped notchedportion 32 and interlockingly connected to thering member 12. Apivot hole portion 31 is formed on a middle portion of the oscillatingmember 11 to insert thepivot shaft portion 27. For example, the oscillatingmember 11 is pivoted to (the outer face side of) the facingplate portion 13 as theend 11a of the oscillatingmember 11 is moved up and down, and the correspondingother end 11b oppositely moves down and up like a seesaw with thepivot shaft portion 27 as a fulcrum. - As shown in
figure 15A , theelastic portion 14 is formed as a ring, and plural smallconvex portions 37 are protruding from one end face. Theelastic portion 14 is composed of elastically deformable resin (or metal), and another end face of theelastic portion 14 is a slidingface 39 to slide (elastically push in the axial inner direction in an assembled and used state described later) on thering member 12. - In
figure 1 , a press-fitfrictional member 15 is formed as a ring, and plural smallconcave portions 38 are formed corresponding to the smallconvex portions 37 of theelastic portion 14. Theelastic portion 14 is attached with the plural smallconvex portions 37 inserted to the smallconcave portions 38 as to rotate (co-rotate) unitedly with the press-fitfrictional member 15. It is also preferable to form theelastic portion 14 unitedly with the press-fitfrictional member 15. - In a half product state shown in
figures 2 and3 , the press-fitfrictional member 15 is disposed on an outer side of eachring member 12, and theelastic portion 14 contacts the outer face of thering member 12. As shown infigure 15B , the slidingface 39 of theelastic portion 14 is arc-shaped under non-compressed state. The press-fitfrictional member 15 is held by acover member 40. Thecover member 40 is composed of a pair of (two-piece) coverhalf bodies 41 of resin. An insertion pin and an insertion hole are formed on thecover half body 41 on assembly corresponding positions (refer tofigure 1 ). Thecover member 40 covers and very compactly stores the press-fitfrictional members 15, thering members 12, the oscillatingmember 11, the facingplate portions 13, thedisc body 16, and the floatingwedge member 6. - In the assembled and used state shown in
figures 4 and5 , theshaft portion 20 of thesecond member 2 is inserted to the throughhole 23 and thefitting hole 19, abolt 43 is screwed into thefemale screw hole 44 to insert thefirst member 1 to thesecond member 2. Thebolt 43 is inserted to awasher 51. In the press-fitfrictional members 15, theelastic portions 14 are elastically deformed by compression of fastening force of thebolt 43. As shown infigure 15C , the slidingface 39 of theelastic portion 14 is made flat face under compressed state and press-fit to thering member 12. That is to say, the press-fitfrictional members 15 are elastically pushing thering members 12 with theelastic portions 14 in the axial inner direction. - Next, method of use (function) of the above-described angle-adjustable hinge of the present invention is described.
- In the engaged state shown in
figures 6A and 6B , thetoothed face 7 of the floatingwedge member 6 is engaged to thegear portion 4, and thecontact face 9 contacts thewedge face 8 to restrict (stop) the relative oscillation of thefirst member 1 and thesecond member 2 in the direction B. The explanation below is under a condition that thesecond member 2 is attached to the fixation portion of the sofa, thefirst member 1 is attached to thearmrest portion 49 or theheadrest portion 48, and thefirst member 1 is oscillated against the (fixed)second member 2. - Next, as shown in
figures 7A and 7B , when thefirst member 1 is oscillated in the direction A, the floatingwedge member 6 slightly moves within thewindow portion 5, and thecontact face 9 is parted from thewedge face 8 to form a slight gap d. When thefirst member 1 is oscillated in the direction A further, the guiding slopedface 35 of the floatingwedge member 6 mounts the stagedportion 36 of thewindow portion 5, thetoothed face 7 of the floatingwedge member 6 is parted from thegear portion 4 by the gap d, and thetoothed face 7 goes over thegear portion 4 with click sound. Even if thefirst member 1 is made oscillate in the direction B against thesecond member 2, the oscillation is restricted (stopped) by wedge function of the floatingwedge member 6, and the posture of thefirst member 1 is kept (held fixed). Although rotational force works on thering member 12 in an arrow N direction (anticlockwise direction in figures) against the facingplate portion 13 by frictional force with the elastic portion 14 (the press-fit frictional member 15) in the oscillation in the direction A, thering member 12 is hitched (against the facing plate portion 13) by thesmall protrusion 33 which contacts the (hitching)concave portion 34. - As shown in
figures 8A and 8B , when thefirst member 1 is oscillated in the direction A further, thetoothed face 7 repeatedly goes over thegear portion 4, and a protrudingportion 28 disposed on an end portion of thegear portion 4 contacts the floatingwedge member 6. - As shown in
figures 9A and 9B , when thefirst member 1 is oscillated in the direction A further to a standing lock-releasing position P0 under the state in which the protrudingportion 28 contacts the floatingwedge member 6, the floatingwedge member 6 is pushed by the protrudingportion 28 and moved to theretreat space 25 to be stored, and thetoothed face 7 is parted from the gear portion 4 (retreat state is made). In this case, theother end 11b of the oscillatingmember 11 is pushed by the floatingwedge member 6 and oscillated. This position is the first position V1. The oscillatingmember 11 oscillates to the first position V1, theend 11a pushes thering member 12, and thering member 12 rotates in an arrow R direction (clockwise direction in figures) only for the small angle θ. - Under the retreat state, the floating
wedge member 6 is stored within theretreat space 25, and the engagement of thetoothed face 7 and thegear portion 4 is released. Therefore, the lock (restriction on oscillation) in the direction B is released, and the free oscillation of thefirst member 1 in the direction B is made possible. - Next, as shown in
figures 10A and 10B , when thefirst member 1 is in the free oscillation M1 in the direction B, thering member 12, although receiving rotational force in the arrow R direction by frictional force of theelastic portion 14, is stopped by thesmall protrusion 33 which contacts the (hitching)concave portion 34. That is to say, during the free oscillation M1 of thefirst member 1 in the direction B, the oscillatingmember 11 is held on the first position V1 and keeping the posture without oscillation, and the floatingwedge member 6 is kept under the retreat state. - In
figures 11A and 11B , when the return action M2 in the direction A for the predetermined small angle θ is conducted during the free oscillation M1 of thefirst member 1 in the direction B, thering member 12, receiving rotational force in the arrow N direction (anticlockwise direction in figures) by frictional force of theelastic portion 14, is rotated. The oscillatingmember 11, of whichend 11a is pushed by therotating ring member 12, is oscillated. This position is the second position V2. The oscillatingmember 11 pushes out the floatingwedge member 6 with theother end 11b to move out of theretreat space 25. The floatingwedge member 6 pushed out of theretreat space 25 is pressed to thegear portion 4 by thespring member 26, and the engaged state, in which thetoothed face 7 is engaged to thegear portion 4, is made (returning to the locked state). - In
figures 12A and 12B , the engaged state, in which thetoothed face 7 of the floatingwedge member 6 is engaged to thegear portion 4 and thecontact face 9 contacts thewedge face 8, is made, the wedge function of the floatingwedge member 6 is recovered to stop the oscillation of thefirst member 1 in the direction B. As described above, the locked state is easily recovered on random positions during the free oscillation of thefirst member 1 from the lock-releasing position P0 to the direction B, the oscillation of thefirst member 1 is restricted on a desired middle inclining position to hold the posture, and angle adjustment is started by oscillation from the middle inclining position to the direction A. - The present invention can be modified. For example, not having the (wedge-shaped)
window portion 5, a plate piece member, etc. may be used instead to press thecontact face 9 of the floatingwedge member 6. And, design and dimensions of thecover member 40 may be changed. - And, the number of the gear teeth of the
toothed face 7 and thegear portion 4 may be more than or less than the above-described numbers depending on cases. And, forming method of the gear teeth may be freely selected from various plastic (press) works, die casting, roulette work, etc. - Especially, the oscillating
member 11 may be freely modified as far as themember 11 is interlocking to move the floatingwedge member 6 in opposite direction (clockwise direction) to push out (take out or draw out) of the retreat state along with the rotation of the ring member 12 (in anticlockwise direction) for the small angle θ fromfigures 10A and 10B tofigures 11A and 11B . - And, the
shaft portion 20 is formed as a regular hexagonal column, and the throughhole 23 is also regular hexagonal as to correspond to theshaft portion 20 in figures. Theshaft portion 20 and the throughhole 23 may be various polygonal or other configurations as far as non-circular and mutually fitting. - As described above, the angle-adjustable hinge relating to the present invention can make the floating wedge member 6 certainly engaged to the gear portion 4 to lock the first member 1 and the second member 2 by a simple operation of slight return movement in the direction A on a random position on way of free oscillation in the direction B from the lock-releasing position P0 because the first member 1 holding the disc body 16 having the non-circular through hole 23 as to freely rotate around the oscillation axis C, the non-circular shaft portion 20 to be inserted to the through hole 23, and the second member 2 fixed to an end of the non-circular shaft portion 20, are provided; the first member 1 and the second member 2 are pivoted as to relatively oscillate by insertion of the shaft portion 20 to the through hole 23, the gear portion 4 is formed on the peripheral edge portion of the disc body 16; the floating wedge member 6, of which one side is the toothed face 7 engaged to the gear portion 4 and another face is the contact face 9 to contact the wedge face 8 formed on the first member 1 side, is provided; relative oscillation of the first member 1 and the second member 2 in the direction B is restricted under an engaged state in which the contact face 9 contacts the wedge face 8 and the toothed face 7 and the gear portion 4 are engaged, the retreat state, in which the floating wedge member 6 is moved to be part from the gear portion 4 by oscillating the first member 1 and the second member 2 relatively in another direction A to the lock-releasing position P0 to release the engagement of the gear portion 4 and the toothed face 7, is made, and the first member 1 and the second member 2 are relatively oscillated in the direction B under the retreat state; and the recovery means 10, which recovers the floating wedge member 6 from the retreat state to the engaged state with the gear portion 4 by a return action M2 of a predetermined small angle θ in the direction A on way of free oscillation M1 in which the first member 1 and the second member 2 are relatively oscillated in the direction B from the lock-releasing position P0, is provided. That is to say, after the engagement of the floating
wedge member 6 and thegear portion 4 is released, the engagement of the floatingwedge member 6 and thegear portion 4 is recovered by the recovery means 10 to restrict the oscillation of thefirst member 1 and thesecond member 2 and angle adjustment can be started from the posture before thefirst member 1 and thesecond member 2 form the predetermined lock recovery position. Therefore, therest portion 50 can be certainly held with a middle inclination posture of a desired inclination angle with a simple operation on a middle position between the final standing posture (lock-releasing position) and the final raid posture (lock recovery position) of therest portion 50 of the sofa S. That is to say, the disadvantage that the locked state of therest portion 50 of the sofa S can't be recovered is solved, and angle adjustment of therest portion 50 can be easily conducted. - And, the hinge is compact with the parts stored within the cover member 40, the floating wedge member 6 can keep the retreat state during the free oscillation M1 in the direction B without functional error, and the gear portion 4 and the toothed face 7 can be engaged by certain movement of the floating wedge member 6 by the return action M2 in the direction A because the first member 1 is provided with a pair of facing plate portions 13 to hold the disc body 16; the recovery means 10 is provided with the ring member 12 which rotates to the facing plate portion 13 within a range of the predetermined small angle θ, the oscillating member 11, of which end 11a is interlockingly connected to the ring member 12 and oscillatable with a middle portion as a fulcrum within a predetermined angular range and another end 11b is disposed as to be pressed to the floating wedge member 6 in the retreat state, and the press-fit frictional member 15, having the non-circular fitting hole 19 to which the shaft portion 20 is fit and the elastic portion 14 unitedly rotating with the shaft portion 20 and elastically pushing in an axial inner direction and sliding on the ring member 12; and under the retreat state, the floating wedge member 6 keeps the retreat state during the free oscillation M1 of the first member 1 and the second member 2 in the direction B, the ring member 12 rotates for the predetermined small angle θ by the frictional force with the elastic portion 14 by the return action M2 in the direction A, and the oscillating member 11 moves the floating wedge member 6 to make the gear portion 4 and the toothed face 7 engaged.
