Keeping out of the way under state, floating wedge parts 6 are incorporated in to be kept out of the way in space 25, and the engagement that gear part 4 and the flank of tooth are 7 is disengaged.Therefore, towards the locking of toppling direction B (swinging restriction), be disengaged, the 1st parts can freely swing towards toppling direction B.
Secondly, as shown in figure 14, the 1st parts 1 are towards the toppling direction B M that freely swings
1situation under, due to and elasticity position 14 between frictional force effect, endless member 12 is subject to torsional interaction along arrow R direction, kick 33 and (engaging with) recess 34 butts engaged.At the 1st parts 1 towards the toppling direction B M that freely swings
1in, tilting member 11 is held in the 1st position V
1, maintaining non-oscillatory posture, floating wedge parts 6 maintain keeps out of the way state.
In Figure 15, the 1st parts 1 are towards the toppling direction B M that freely swings
1way in, if carry out towards stand direction A retract small angle theta retract action M
2, due to and elasticity position 14 between frictional force effect, endless member 12 will be subject to moment of torsion and rotate along arrow N direction (counter clockwise direction of figure).The endless member 12 that one end 11a of tilting member 11 can be rotated pushes and swings.This reach the 2nd position V
2.The other end 11b of tilting member 11 makes floating wedge parts 6 release and move from keep out of the way space 25.By the floating wedge parts 6 of releasing from keep out of the way space 25, by spring members 26, by gear part 4, pushed, make the flank of tooth 7 and gear part 4 engagements form engagement (recovery lock-out state).
In Figure 16, the flank of tooth 7 in floating wedge parts 6 and gear part 4 engagements, and under the engagement of bearing surface 9 and wedge surface 8 butts, the wedging action of floating wedge parts 6 recovers, and stops the 1st parts 1 towards the swing of toppling direction B.So, at the 1st parts 1 from latch-release position P
0beginning swings the optional position in way towards toppling direction B, all can recover simply lock-out state, in desirable intermediate, inclined position, the posture that keeps restriction the 1st parts 1 to swing, make it from middle obliquity, start to swing towards the direction A that stands, and start to carry out angle adjustment.
Should illustrate, the design of angle adjustment gold utensil 3 can be changed, and for example, in the situation that there is no (wedge shape) window portion 5, can replace by the sheet like part that pushes the bearing surface 9 of floating wedge parts 6.And the design of cover 40 and size are also variable.
In addition, the number of teeth of the number of teeth of the flank of tooth 7 and gear part 4 is compared the above-mentioned number of teeth can difference according to circumstances freely increase or reduce.And the production method of tooth can freely be selected, various plasticity (punching press) processing, die-casting process or annular knurl processing etc. all can.
Particularly, if tilting member 11 has linkage part, make from Figure 10 to Figure 11, along with the rotation of endless member 12 in small angle theta (counterclockwise) scope, floating wedge parts 6 are (clockwise) movement in the opposite direction, from keep out of the way state, released (take out of or pull out), this linkage part design can be carried out variously freely changing.
In addition, as shown in legend, axial region 20 is made into positive hexagonal column, and through hole 23 is also made into regular hexagon shape corresponding thereto.Axial region 20 and through hole 23 are non-circular for what can mutually embed, also can be made into various polygons or other shapes.
Should illustrate, design of the present invention is also variable.For example, armrest part 49 being connected in to a portion 47 also can.
As mentioned above, the sofa the present invention relates to possesses armrest part 49, and it is linked to the fixed part 45 of sofa by angle adjustment gold utensil 3, can freely adjust the form of angle, is mounted.Sofa can switch between lock-out state and free state, lock-out state is that armrest part 49 is when can swing to the direction A that stands, armrest part 49 is limited to the swing of toppling direction B, free state is by making armrest part 49 be the latch-release posture of standing state, restriction was lost efficacy, and armrest part 49 can swing to toppling direction B.Under free state, for the posture T from latch-release
0middle recovery locking, topples over posture T at armrest part 49 towards level
1, in the way swinging along toppling direction B, with intermediate, inclined posture T arbitrarily
1, can by armrest part 49 is retracted towards the direction A that stands regulation small angle theta retract action M
2, the restriction of losing efficacy is recovered, form lock-out state, armrest part 49 keeps posture.Therefore,, under free state, at armrest part 49, towards toppling direction B, swing any intermediate, inclined posture T in way
1, by the direction A that stands of court, retract a little armrest part 49, can make the restriction of losing efficacy recover to form lock-out state.That is, make armrest part 49 be the latch-release posture T of standing state
0thereby after making restriction inefficacy, in order to recover locking, do not need the state of being up to the standard to topple over posture T
2, armrest part 49 can recover lock-out state, keeps intermediate, inclined posture T arbitrarily
1, and at this intermediate, inclined posture T
1can start to carry out angle adjustment.That is, eliminated armrest part 49 and become and cannot recover this above-mentioned problem of lock-out state owing to being hindered (with barrier butt) by barrier, can be easily and promptly carry out angle adjustment.
Should illustrate, the sofa the present invention relates to possesses headrest portion 48, and it is linked to the top edge of backrest 46 by angle adjustment gold utensil 3, can freely adjust the form of angle, is fixed.Above-mentioned sofa can switch between lock-out state and free state, lock-out state is that headrest portion 48 is when can swing to the direction A that stands, headrest portion 48 is limited to the swing of toppling direction B, and free state is by making headrest portion 48 be the latch-release posture T of standing state
0, restriction was lost efficacy, headrest portion 48 can swing to toppling direction B.Under free state, for the posture T from latch-release
0middle recovery locking, topples over posture T in headrest portion 48 towards level
1, in the way swinging along toppling direction B, with intermediate, inclined posture T arbitrarily
1, can by headrest portion 48 is retracted towards the direction A that stands regulation small angle theta retract action M
