In addition, according to the first embodiment of the present invention, a kind of armrest with two rotating shaft mechanisms that roll can also be formed, this armrest comprises the two rotating shaft mechanism of a set of above-mentioned rolling, support, a cantilever and a handrail, these parts wherein elaborate above, repeat no more herein.
Below more by reference to the accompanying drawings, the armrest box be arranged symmetrically with for the two rotating shaft mechanism of two cover rollings, describes the use procedure that this has the armrest box mechanism of two rotating shaft mechanism that rolls in detail.
As shown in Fig. 8, Fig. 9, Figure 10 A and Figure 10 B, after installation, the line in the virtual center of circle of the first circular arc 221 of support 2 left and right sides is defined as S. A. A1, the line in the center of circle of both sides second circular arc 222 is defined as S. A. A2, as shown in Fig. 8 and Figure 10 A, according to two S. A. A1 and A2, the one-way movement of handrail is divided into two stages, wherein:
First stage, handrail rotates up 0 °-28 ° around A1 axle along clockwise direction from horizontal surface.According to the function of handrail, first stage is divided into 0 ° ~ 20 ° and 20 ° ~ 28 ° two angular interval again.Wherein in 0 ° ~ 20 ° intervals, handrail can hover and bearing load, can not close; In 20 ° ~ 28 ° intervals, handrail can hover, can not bearing load, just can not close as long as can close but get back to 20 ° before not to 28 ° again.
Be turned to the process of 20 ° of angles at handrail from 0 °, as shown in Figure 10 a, the operating effort that handrail is subject to occupant starts to rotate in a clockwise direction, as shown in Figure 11 VIA, engaged with the second unidirectional ratchet 33 on unidirectional ratchet gear 3 by the first unidirectional ratchet 12 of disc seat 1, and the engaging of the second two-way ratchet 61 on cotter pilotage ratchet 6 and the first two-way ratchet 52 on two-way ratchet gear 5, operating effort is made to be delivered to cotter pilotage ratchet 6 from disc seat 1, simultaneously, due to the interaction on the inclined-plane of operating effort between ratchet, create axial component, as shown in Figure 11 VIA, unidirectional ratchet gear 3 and two-way ratchet gear 5 is made to overcome the thrust of coil spring 4, move axially towards direction adjacent to each other respectively, cause the first unidirectional ratchet 12 of the second unidirectional ratchet 33 on unidirectional ratchet gear 3 and disc seat 1, and the first two-way ratchet 52 on two-way ratchet gear 5 and the instantaneous disengaging simultaneously of the two-way ratchet 61 of second on cotter pilotage ratchet 6, and back occupant ongoing operation power and coil spring 4 elastic force effect under batch (-type) engagement, as shown in Figure 10 VIA and Figure 11 VIA contrast, now, unidirectional ratchet gear 3 and two-way ratchet gear 5 can start to roll respectively by the first straight-tooth gear 31 and the second straight-tooth gear 51 circular arc rack rails 21 along support 2.Meanwhile, along circular arc 22 rolling movement of support 2 under the cotter pilotage 65 of roller bearing 7 on cotter pilotage ratchet 6 drives, as shown in Figure 10 B and Figure 12 A.As shown in Figure 11 VIB, unidirectional ratchet gear 3 move axially the variant part 92 making the displacement circular conical surface 32 on unidirectional ratchet gear 3 start to extrude stop bit shell fragment 9.If now conter clockwise closes handrail, the second unidirectional ratchet 33 then on unidirectional ratchet gear 3 can engage again again with the first unidirectional ratchet 12 of cantilever 1, because the flank of tooth of unidirectional ratchet interacts, can not produce axial force makes unidirectional ratchet depart from, and makes unidirectional ratchet gear 3 and two-way ratchet gear 5 stop rolling simultaneously.Namely in this process, handrail can not be closed, but can hover and can bearing load.And can according to the reference radius of circular arc rack rails 21 and straight-tooth gear 31, the number of teeth of the second unidirectional ratchet 33 and the arc length of the first circular arc 221 carry out the angle of adjustable handrail hovering position, thus determine that handrail hovers and the control position that carries and number of positions simultaneously.
Until when handrail forwards 20 ° to, as illustrated in fig. 12, the cotter pilotage 65 on cotter pilotage ratchet 6 moves to the first circular arc 221 and the second circular arc 222 has a common boundary, in four roller bearings 7, except roller bearing 7-4 enters the second circular arc 222, all the other roller bearings 7-1,7-2 and 7-3 are still in the first circular arc 221.Now as shown in Figure 12 B and Figure 12 C, the second displacement inclined-plane 352 on unidirectional ratchet gear 3 first conjugates inclined-plane 132 with on rotating circular disk seat 1 and starts to contact.
Continue to be turned to the process of 28 ° from 20 ° at handrail, handrail continues upset from 20 °, along with the rolling of unidirectional ratchet gear 3, the second displacement inclined-plane 352 on the unidirectional ratchet gear 3 of keeping in touch and first of cantilever 1 conjugates between inclined-plane 132 and creates an axial thrust, promote unidirectional ratchet gear 3 towards continuation moving axially away from disc seat 1, now as Figure 13 VIA, the second unidirectional ratchet 33 and the first unidirectional ratchet 12 do not engage, and handrail can not be carried.The Direction distortion towards the stage portion 142 near disc seat 1 is continued, as shown in Figure 10 VIB under the moving axially of unidirectional ratchet gear 3 makes the extruding of the displacement circular conical surface 32 of the variant part 92 of stop bit shell fragment 9 on ratchet gear 3.Simultaneously, coil spring 4 is compressed, increase the pressure of two-way ratchet gear 5 towards cotter pilotage ratchet 6 axis, first two-way ratchet 52 of two-way ratchet gear 5 maintains batch (-type) with the second two-way ratchet 61 of cotter pilotage ratchet 6 and engages, and ensures that handrail be not subject to balance with himself under External Force Acting thus realize the static hovering of handrail.
Until handrail is turned to 28 °, as shown in FIG. 13A, the cotter pilotage 65 on cotter pilotage ratchet 6 moves in the second circular arc 222 completely, and in four roller bearings 7, except roller bearing 7-2 is still in the first circular arc 221, all the other roller bearings 7-1,7-3 and 7-4 all enter in the second circular arc 222.Now, as shown in Figure 13 B and Figure 13 C, first displacement inclined-plane 132 and second conjugates inclined-plane 352 and no longer contacts with each other, and the first stop bit plane 131 on disc seat 1 starts to contact with the second stop bit plane 351 on unidirectional ratchet gear 3, to maintain the axial location of unidirectional ratchet gear 3, as shown in Figure 11 VIB, and the variant part 92 of stop bit shell fragment 9 arrives maximum deformation quantity, displacement circular conical surface 32 now on unidirectional ratchet gear 3 crosses variant part 92, variant part 92 loses the pressure of displacement circular conical surface 32, and the variant part 92 of stop bit shell fragment 9 returns to the position before distortion.Second unidirectional ratchet 33 of unidirectional ratchet gear 3 departs from completely with the first unidirectional ratchet 12 of disc seat 1, and handrail can not be subject to the impact of the first unidirectional ratchet 12 and the second unidirectional ratchet 33 again and can not close.
Subordinate phase, handrail forwards 88 ° around S. A. A1 to from 28 °.This stage handrail can hover also can along unlatching or closing direction rotary motion, can not bearing load.
As shown in Figure 14 B and Figure 14 VIB, handrail upwards overturns from 28 ° of continuation, because now the first unidirectional ratchet 12 of disc seat 1 and the second unidirectional ratchet 33 of unidirectional ratchet gear 3 depart from completely, simultaneously because the first straight-tooth gear 31 and the second straight-tooth gear 51 engage with the circular arc rack rails 21 of support 2, the motion rotated around S. A. A2 can not be there is in unidirectional ratchet gear 3 and two-way ratchet gear 5 self, so the rotation of disc seat 1 only can drive cotter pilotage ratchet 6 to rotate in the second circular arc 222, now, as shown in Figure 14 VIB, the position-arresting part 91 of stop bit shell fragment 9 props up the second stop bit plane 351 on unidirectional ratchet gear 3, with the pressure of counterpoised helical springs 4 for unidirectional ratchet gear 3, bonding is constant to the axial location of ratchet gear 3.In the process, handrail can swimmingly along opening or closing direction rotation, on two-way ratchet gear 5 first two-way ratchet 52 and the two-way ratchet 61 of second on cotter pilotage ratchet 6 all the time batch (-type) engage, and when there is no occupant's operating effort while the first two-way ratchet 52 just in time engages with the second two-way ratchet 61, handrail self gravitation is transformed into the power at the first two-way ratchet 52 and the second two-way ratchet 61 place and coil spring 4 and just in time balances for the pressure of two-way ratchet gear 5, can ensure that handrail can hover this moment, one of this position hovering position being design.This state to rotate to along closing direction in the process of first stage at handrail and also can keep always, so just can ensure that handrail can closing movement smoothly, the situation about can not close run into when first stage is opened before there will not be.
At handrail from 28 ° to close to the dwell period of 0 °, body function, the relative position of part is consistent with the open and close handrail stage from 28 ° to 88 ° again to 28 °, and principle of work is distinguished to some extent: in the open and close handrail stage from 28 ° to 88 ° again to 28 °, disc seat 1 and cotter pilotage ratchet 6 do the rotary motion along S. A. A2 relative to unidirectional ratchet gear 3 and two-way ratchet gear 5, at handrail from 28 ° to close to the stage of 0 °, unidirectional ratchet gear 3 and two-way ratchet gear 5 relative to the spinning motion of disc seat 1 and cotter pilotage ratchet 6, i.e. unidirectional ratchet gear 3, two-way ratchet gear 5, disk 1 and cotter pilotage ratchet 6 rotate along S. A. A1 simultaneously, unidirectional ratchet gear 3 simultaneously, two-way ratchet gear 5 can also do rotation movement along its central axis.When handrail is about to close, as shown in fig. 15, variant part 92 on stop bit shell fragment 9 is along reset inclined-plane 362 deformation in compression of unidirectional ratchet gear 3, until contact with reset arc surface 361, now as shown in Figure 15 VIB, unidirectional ratchet gear 3 has departed from the support of stop bit shell fragment 9, under the pressure effect of coil spring 4, move towards the axial direction away from two-way ratchet gear 5, get back to initial position, now handrail is closed completely.
The present invention utilizes ratchet, gear, rack rails, the cooperation of the parts such as spring, realize handrail successively to rotate around two virtual axle (i.e. A1 axle and A2 axle), thus change the path of motion of handrail, decrease the restriction that mechanism arranges handrail moulding and space.Meet multiple positions hovering in path of motion simultaneously, and as the control position of handrail, the different requirements of different users to armrest positions comfort level can be met at several diverse location bearing load within the specific limits.
Above-described, be only preferred embodiment of the present invention, and be not used to limit scope of the present invention, the above embodiment of the present invention can also make a variety of changes.Namely every claims according to the present patent application and description are done simple, equivalence change and modify, and all fall into the claims of patent of the present invention.The not detailed description of the present invention be routine techniques content.
