Slide section 425 is located at flat part 4211 towards on the outer surface of connection sheet 412, and the width of the slide section 425 is about
For L3, be accommodated in through hole 4121, thus two side external surfaces of length direction always with the inside table of through hole 4121
Face is in contact, so that the freedom degree of its left and right directions when moving along the vertical direction of receiving portion 421 is limited, will not move down upper
Double swerve occurs in dynamic process.
Figure 10 is the structural schematic diagram of the cover piece of the embodiment of the present invention one, and Figure 11 is the B-B direction cross-sectional view of Figure 10.
As shown in Figures 10 and 11, cover piece 43 is an integrally formed component, central part have one to path
The tabletting 431 that guiding piece 41 extends, tabletting 431 are equipped with second fixture block 432 corresponding with 424 position of the first fixture block.
The cover piece 43 of the present embodiment is also made of the high molecular material with certain toughness and elasticity, therefore tabletting 431
Also with good elasticity (performance for being bent after being pressurized and being replied after pressure removes).Meanwhile with 424 class of the first fixture block
Seemingly, the second fixture block 432 is also in triangular shape from the side.
In addition, cover piece 43 is whole to be rectangle sheet, upper and lower ends have to be extended towards 41 direction of Route guiding part
Bending section, therefore after being mounted to waist panel 20 and being covered on Route guiding part 41, the inner surface and path portion of cover piece 43
There is certain interval, the distance in the gap is suitable with the diameter in support rail portion 31, so that support is horizontal between 411 surface 41A
Bar portion 31 can move up and down between path portion 411 and cover piece 43.
Below in conjunction with the working principle of the thing to sit on 100 of Detailed description of the invention the present embodiment.
Figure 12 is the side structure schematic view of the thing to sit on of the different conditions of the embodiment of the present invention one.
In Figure 12, S1 is the thing to sit on of resting state, and S2 is the thing to sit on of working condition, thing to sit on when S3 is adjustment state, F1
And F2 is the rotation direction of waist panel 20 when user stirs forward waist panel 20, the arrow between S1, S2 and S3 indicates thing to sit on 100
State change sequence.
As shown in figure 12, mainly there are two different states, i.e. working condition and rest shape for the thing to sit on 100 of the present embodiment
State.Wherein, working condition S2 is working condition sitting posture (the straight and upright seat of the sitting posture and waist to lean forward including waist with user
Appearance) corresponding state, resting state S1 is shape corresponding with the resting state sitting posture of user (sitting posture of waist layback)
State, two states can be stirred waist panel 20 (dialling waist panel 20 forwards for example, holding 20 edge of waist panel) by user
Movement switch over.
In addition, thing to sit on 100 also has the adjustment state S3 passed through when being switched to resting state S1 from working condition S2, when making
When user stirs the waist panel 20 of the thing to sit on 100 in working condition S2 further along, thing to sit on 100 can enter the adjustment state
S3, the user waist being then subject in waist panel 20 back pressure (i.e. user carry out backward wing when, waist swing backward and
The active force backward being applied on waist panel 20) the lower rotation that the direction F3 occurs of effect, to return to resting state S1.
As noted previously, as the toggle action of user, in the thing to sit on 100 of different conditions, the position of waist panel 20 is different
's.Moreover, change in location occurs as waist panel 20 is stirred by user, the position of other component also mutually strains generation
It is dynamic.Below in explanation, the position corresponding with resting state of all parts is known as resting state position, it is corresponding with working condition
Position be known as working condition position, position corresponding with adjustment state is known as adjusting position.
Figure 13 is the movement routine control assembly working principle diagram of the embodiment of the present invention one.
It is acted in order to which movement routine control assembly 40 is better described to the path clustering in support rail portion 31, it is right in Figure 13
Movement routine control assembly 40 is exaggerated and is simplified to other structures, and seat plate 10, waist panel 20, seat plate 10 is omitted
With the structures such as the coupling part of waist panel 20 and the coupling part of supporting element 30 and seat plate 10.
As shown in FIG. 12 and 13, since the interconnecting piece 22 of 20 lower part of waist panel is mounted on seat plate 10 by shaft 23, because
, when user stirs waist panel 20, which can rotate relative to seat plate 10 for this.
Simultaneously as support rail portion 31 is enclosed in the receiving portion 421 of path adjustment part 42 and is covered by cover piece 43,
Receiving portion 421 is to be located on Route guiding part 41, therefore support rail portion 31 is limited by movement routine control assembly 40 again
System is at the back position of waist panel 20.Correspondingly, when user stirs waist panel 20 to allow waist panel 20 to rotate, due to supporting element
30 are rotatably mounted on seat plate 10 by connecting bar portion 32, thus support rail portion 31 by with the rotation of waist panel 20 and
It moves, also rotates so that supporting element 30 is whole.
Specifically, when thing to sit on 100 is in resting state S1, waist panel 20 is located at rearward position, support rail portion 31 with
Positive stop end 41C is abutted against.In this state, if user is rested on waist panel 20 using the sitting posture of layback by waist, waist
Portion will impose an active force backward to waist panel 20, and the withstanding effect of support rail portion 31 and positive stop end 41C will make waist panel
20 can not rotate backward.A kind of support construction of triangle is formd between waist panel 20, seat plate 10 and supporting element 30 as a result,
Positive stop end 41C is equivalent to the supporting point of supporting element 30 Yu waist panel 20.
When user stirs waist panel 20 forward, waist panel 20 is just rotated forward according to the direction F1 shown in Figure 12.Due to branch
Support member 30 is rotatably mounted on seat plate 10, therefore supporting element 30 is also driven by waist panel 20 and rotates slightly forward, so that waist
Plate 20, seat plate 10 and supporting element 30 are formed by triangular structure and deform.In the process, for waist panel 20,
The contact point of itself and supporting element 30 is moved down.It is exactly 31 edge of support rail portion for the internal structure embodied with Figure 13
The surface 41A of path portion 41 move down.
As shown in figure 13, at resting state S1, support rail portion 31 is located at the upper end position of receiving portion 421, this
When tabletting 431 on the second fixture block 432 mutually crimped with the surface in blade portion 423.At this point, tabletting 431 is in deformed state, " top
Firmly " path adjustment part 42, so that autonomous will not occur for path adjustment part 42.Only when support rail portion 31 moves down
To the lower end position of receiving portion 421, and when abutting against with the lower end inner surface, path adjustment part 42 can be just supported
Cross bar portion 31 drives and moves down.
When support rail portion 31 drives path adjustment part 42 to be moved downward at X point, since tabletting 431 has back always
The trend of multiple original form, therefore the tabletting 431 is just applied with the power towards Route guiding part 41 to path adjustment part 42,
So that receiving portion 421 is turned to using the shaft that protrusion 422 is formed as center of rotation at X, and then along the second sliding rail portion
41E enters limit groove portion 41B.Meanwhile support rail portion 31 also enters limit groove portion 41B by its guidance.
Since the upper inside surface angle with horizontal plane of limit groove portion 41B is smaller, support rail portion 31 is entering limiting slot
Limit groove portion 41B cannot be moved out after portion 41B from above principal and subordinate, but is abutted against with the surface of limit groove portion 41B, thus logical
It crosses path guiding piece 41 and support is formed to waist panel 20.At this point, thing to sit on 100 just reaches working condition S2.
In this state, as shown in figure 13, a surface on a surface of the first fixture block 424 and the second fixture block 432
It is in contact, so that path adjustment part 42 " has been hooked " in tabletting 43, path adjustment part 42 will not independently be moved down, this is also functioned to
Prevent support rail portion 31 from removing the effect of limit groove portion 41B.Since the first fixture block 424 is located on the first free-end 4211,
First free-end 4211 extends towards cover piece 43, therefore cooperation is more readily formed in two fixture blocks, allows tabletting 43 can be certainly
It hooks path adjustment part 42 and is not easy to loosen.
In addition, first fixture block 424 is mutual on the above-mentioned surface of arrival with the second fixture block 432 due to the elastic reaction of tabletting 43
Collision can be generated when the state of contact and can issue slight impact sound, and user has arrived at according to the impact sound, that is, knowable
Working condition S2, so as to stopping stirring the movement of waist panel 20 and begin to use thing to sit on 100.Due under working condition S2
The position that waist panel 20 is located relatively forward, user can be leaned against waist on waist panel 20 using working condition sitting posture, to allow
Waist is supported.
When user stirs the waist panel 20 under working condition S2 further along, waist panel 20 will rotate further along,
So that support rail portion 31 is also further moved down relative to waist panel 20.Correspondingly, path adjustment part 42 is also supported cross bar
Portion 31 drive, which overcome after the active force of tabletting 43 " hooking " i.e. disengaging tabletting 43 and downward out limit groove portion 41B.
When the lower part of path adjustment part 42 is moved to the limit lower part groove portion 41B, the just inside with cover piece 43 of blade portion 423
Surface abuts against to which " support " is on cover piece 43, so that path adjustment part 42 and support rail portion 31 will not move still further below
It is dynamic.
At this point, the upper portion of path adjustment part 42 passes through protrusion 422 " frame " on the first sliding rail portion 41D, lower end
Divide then by the end portion " frame " of receiving portion 421 on the second sliding rail portion 41E, so that path adjustment part 42 is showed and is supported on
Limit the state (that is, vacantly frame is on limit groove portion 41B) on groove portion 41B.Meanwhile first fixture block 424 another surface
It contacts with each other just with another surface of the second fixture block 432, the deformation recovery power of tabletting 43 passes through the effect of two fixture blocks
And be applied to path adjustment part 42 so that blade portion 423 is constantly against on cover piece 43, path adjustment part 42 cannot automatically to
Above or move down.In addition, the first free-end 4211 extends towards cover piece 43, which also has elasticity, this
But also the first free-end 4211 also provides certain resistance (that is, if road in its longitudinal direction when two fixture blocks contact with each other
Diameter adjustment part 42 moves up, and needs the elastic-restoring force for overcoming the first free-end 4211 also to allow it to generate deformation) so that
Path adjustment part 42 is more less likely to occur autonomous.
Thing to sit on 100 reaches adjustment state S3 as a result, and correspondingly, support rail portion 31 also reaches adjusting position.
Similarly, due to the elastic reaction of tabletting 43, the first fixture block 424 and the second fixture block 432 reach it is above-mentioned another
Collision can be generated when the state that surface contacts with each other and issues impact sound, and user has arrived at according to the impact sound, that is, knowable
Adjustment state S3, so as to stopping stirring the movement of waist panel 20 and carry out sitting posture adjusting, that is, waist leans on backward and by work
State sitting posture is changed into the adjusting of resting state sitting posture.
During user's adjusting sitting posture, waist will rest on waist panel 20 and apply one backward to waist panel 20
Active force, allow waist panel 20 to rotate backward therewith.Correspondingly, support rail portion 31 is moved up with respect to waist panel 20.This mistake
Cheng Zhong, since path adjustment part 42 is supported on limit groove portion 42B by the active force of tabletting 43 always, support rail portion 31
It can only adjust in path and be continued to move on the 421A of face, thus in the case where not entering limit groove portion 42B by limit groove portion 41B
Place.That is, in this case, support rail portion 31 is just along the path different from when entrance limit groove portion 42B via limit
It is moved up at the groove portion 42B of position.Then, support rail portion 31 will reach 421 upper end of receiving portion and in receiving portion 421
Side surface abuts against, to generate upward active force to path adjustment part 42, which overcome path adjustment part 42
The active force of tabletting 431 causes the first fixture block 424 and the second fixture block 432 to be mutually disengaged, path adjustment part 42 can supported
It is moved up under the drive in cross bar portion 31.Finally, support rail portion 31 reaches at limit end 41C, so that thing to sit on 100 returns to not
Breath state S1.
As described above, the transition process between three states of the thing to sit on 100 of the present embodiment be always resting state S1 →
Working condition S2 → adjustment state S3 → resting state S1 ....That is, thing to sit on 100 can be stirred forward via user
The effect of waist panel 20 and be directly in working condition S2 from resting state S1 transformation, and stir waist panel 20 further along in user
When, thing to sit on 100 must first reach adjustment state S3, then can just return to resting state S1.Correspondingly, path adjustment part 42 and road
It cooperates between diameter guiding piece 41, cover piece 43, control support rail portion 31 carries out such as in the state transition process of thing to sit on 100
Lower movement: when user stirs forward the waist panel 20 of resting state position, support rail portion 31 is first moved to adjusting position,
Then it is moved to resting state position followed by the layback of user (i.e. at limit end 41C)；Waist in resting state position
When plate 20 is stirred forward, support rail portion 31 is directly moved to working condition position (i.e. limit groove portion from resting state position
In 41B).
As a result, if desired user changes sitting posture, it is only necessary to reach forward and allow when using the thing to sit on 100 of the present embodiment
The first waist panel away from keyboard of waist, then backhand is stirred waist panel 20 and is stirred according to the impact sound stopping between fixture block, mistake
It does not need to leave thing to sit on 100 in journey, does not need to bend over yet or sway one's hips.
The action and effect of embodiment
According to thing to sit on provided in this embodiment, since movement routine control assembly can control the mobile road in support rail portion
Diameter, when so that user stirring forward the waist panel of resting state position, it is right that support rail portion is first moved to an adjusting position
After move again to resting state position, when waist panel of the user in resting state position is stirred forward, support rail portion directly from
Resting state position is moved to working condition position, therefore user only needs to be stirred forward this movement of waist panel
The state of thing to sit on is allowed to change.So the thing to sit on of the present embodiment can adapt to the different sitting postures of user, and do not need additional
Adjusting means can allow user realize adjust operation, it is easy to use.
In the present embodiment, since movement routine control assembly includes three mutually matched components, i.e. Route guiding part, road
Diameter adjustment part and cover piece, wherein Route guiding part is capable of providing the movement routine in support rail portion, and cover piece can pass through covering
Route guiding part and support rail portion is limited on Route guiding part, path adjustment part can by be supported on limit groove portion on
And change the movement routine in support rail portion, therefore support rail portion can be moved when waist panel is struck along scheduled different paths
It is dynamic, to achieve the effect that be struck with waist panel and accordingly change position, thing to sit on state is allowed to change.Also, the present embodiment is only
Three components are needed to can be realized as regulatory function, which is molded and can manufacture, can also be only when installation
It by fixing pieces such as screws, therefore manufactures installation and is all relatively easy to, cost is relatively low.
In addition, in adjustment state, tabletting can push down path adjustment part thus by path tune since cover piece has tabletting
One integral piece is maintained at the position being supported in limit groove portion, and then can guarantee that support rail portion is moved along path adjustment face, in work
When making state, tabletting can hook path adjustment part to prevent path adjustment part i.e. support rail portion from taking off from limit groove portion
Out, therefore, path adjustment part can be guaranteed in the stability of adjustment state position and working condition position, be not easy to send out
Raw displacement, so that it is more stable to the path corrective action in support rail portion.Correspondingly, the state of the thing to sit on of the present embodiment changes
Change process is also more stable, will not there is a situation where when waist panel is struck state change mistake.
Further, since receiving portion has the first free-end extended to cover piece direction, which can be with pressure
Piece cooperates, so that the position stabilization of above-mentioned path adjustment part is further guaranteed.
Moreover, the first fixture block being arranged on the first free-end and the second fixture block being arranged in tabletting are triangular in shape,
Therefore respectively there are two the surfaces that can be worked in coordination for tool.The mutual cooperation of two fixture blocks not only further enhances rheme
Set stabilization, additionally it is possible to issue impact sound when reaching working condition or adjustment state, to prompt user, allow
User correspondingly stops stirring waist panel.
In embodiment, the through hole being arranged in the slide section and connection sheet that are arranged in receiving portion cooperates, and allows path
Offset on left and right directions will not occur when moving for adjustment part, this can also guarantee the present embodiment in the middle part of state change process
The mobile stability of part.
