Embodiment
With reference to figure 1, Fig. 2, the present invention provides a kind of lifting structure 1 of chair headrest, is used for being set up on a chair back 2,
It includes a lifting seat 10, one headrest 20 and one flexibly positioned bar 30 of bottom allotment.
The lifting seat 10 is releasably on the chair back 2, and as shown in Figure 4, Figure 5, the indoor design of lifting seat 10 is more
Individual guide groove includes one oblique mouthful of guide groove 11, one and leads straight guide groove 12, a curved guiding groove 13 and multiple ladder guide grooves 14.
As shown in Figure 4, Figure 5, the oblique mouth guide groove 11 is located at axial centre (such as Fig. 3, Fig. 5 the Y-axis line of the lifting seat 10
It is shown) the nearly top on one side for being separated locates, and by the top down extension of the lifting seat 10；It is oblique that the straight guide groove 12 of the master is located at this
Entrance guide groove 11 extends downward into bottom with one side and by the top of the lifting seat 10；The curved guiding groove 13, which is located at the oblique mouth, leads
Between the bottom of groove 11 and the top of the straight guide groove 12 of the master, the oblique guide groove 12 straight with the master of mouth guide groove 11 is set to connect, such as
Shown in Fig. 5, Fig. 6, wherein the guide groove bottom surface of the curved guiding groove 13 is further formed towards the bottom surface of the oblique mouth guide groove 11
Drop angle slope 131, and it further forms one towards the bottom surface of the straight guide groove 12 of the master with drop (as shown in Fig. 6 height H)
One steep descending grade 132；And the plurality of ladder guide groove 14 its by the straight guide groove 12 of the master relative another side the lifting seat 10 bottom
To top sequential, wherein each ladder guide groove 14 has a stop slot point 15, and be located at the ladder guide groove 14 of the top
The top of top guide groove 12 straight with the master connects and defines a upper end slot point 16, and under the ladder guide groove 14 of bottom
The bottom of portion's guide groove 12 straight with the master connects and has defined end slot point 17.
The lifting seat 10 further locks integrally with positioning piece 50, but is not used to the limitation present invention, the keeper 50
With a buckle straight-bar 51 and a buckle cross bar 52, the buckle straight-bar 51 and buckle cross bar 52 for making the keeper 50 can further press from both sides
Gu the top of the framework 201 in the chair back 2, and the chair back 2 of various different shape sizes can be applied to.
The upper end of the headrest bottom allotment 20 links a headrest 3 so that the headrest 3 is obtained with the synchronization lifting of headrest bottom allotment 20
Slide, the headrest bottom allotment 20 has a straight runner 21 for being releasably located on the lifting seat 10, when the headrest bottom allotment 20
When being combined into one with the lifting seat 10, the lifting structure 1 is combined into one with the chair back 2.
The upper end of the flexibly positioned bar 30 be fixedly arranged in the straight runner 21 of the headrest bottom allotment 20 axial centre (such as Fig. 3,
Shown in Fig. 5 Y-axis line) on, its lower end forms a positioning end 31, and the positioning end 31 can rely on the material of the flexibly positioned bar 30
In the elastic axial centre (as shown in Fig. 3, Fig. 5 Y-axis line) to be resiliently retained in the straight runner 21 so that the positioning end 31
It can be swung by elastic force in axial centre (as shown in Fig. 3, Fig. 5 Y-axis line) (such as Fig. 3 X directions of arrow institute
Show).
A stabilizing member 40 is further provided with the straight runner 21 of the headrest bottom allotment 20, but is not used to the limitation present invention, should
Stabilizing member 40 has a fixing hole 41 and a fixing groove 42, the upper end of the flexibly positioned bar 30 is embedded and is fixed on this and fixes
In hole 41, and an epimere local 32 for the flexibly positioned bar 30 is embedded in and be fixed in the fixing groove 42 so that this is flexibly positioned
Bar 30 can rely on elastic properties of materials to be maintained in the axial centre of the lifting seat 10 (as shown in Fig. 3, Fig. 5 Y-axis line).
With reference to figure 2- Fig. 5, when the headrest bottom allotment 20 is assembled on the lifting seat 10, the flexibly positioned bar 30 is determined
Position end 31 can rely on elastic properties of materials bending to leave axial centre (such as Fig. 3, Fig. 5 Y-axis line (as shown in Fig. 3 X directions of arrow)
It is shown) and import in the oblique mouth guide groove 11 of the lifting seat 10, as shown in Figure 5,6, the positioning end 31 is slided and relied on still further below
Elasticity is replied (as shown in Fig. 3 X directions of arrow) toward the curved guiding groove 13 to axial centre (as shown in Fig. 3, Fig. 5 Y-axis line)
Decline slop 131 tiltedly on crawl, and cross the steep descending grade 132 and be directed into the straight guide groove 12 of the master, because of the steep court of descending grade 132
There is high low head (as shown in Fig. 6 height H) to the bottom surface of the straight guide groove 12 of the master, be located at the positioning end 31 and be less than the steep drop
It is not easy reversely to slide back to the oblique mouth guide groove 11 again on the straight bottom surface of guide groove 12 of the master on slope 132.
With reference to figure 1, Fig. 4, Fig. 5, wherein the master that the lifting seat 10 is directed into when the positioning end 31 of the flexibly positioned bar 30 is straight
After in guide groove 12, the positioning end 31 slides down to further along the straight guide groove 12 of the master stops at the lower end slot point 17 (as schemed
1st, shown in Fig. 5 position A) on.
When the headrest bottom allotment 20 is pulled and when making the 31 synchronous upward sliding of positioning end, the positioning end 31 must leave this
Lower end slot point 17 (as shown in Fig. 1, Fig. 5 position A) and along bottom the ladder guide groove 14 and slide into and stop at the rank
To form a minimum height and position on the stop slot point 15 (as shown in Fig. 1, Fig. 5 position B) of terraced guide groove 14.
By above-mentioned same operation mode, it can similarly make " B ＂ stop slot of the positioning end 31 from next ladder guide groove 14
Point 15 slides and stops at " the C ＂ stop slots point 15 of a ladder guide groove 14；Or from " C ＂ stop slots point 15 is slided and stopped at
" the D ＂ stop slots point 15 of one ladder guide groove 14；Or from " D ＂ stop slots point 15 slides and stops at " the E ＂ of upper ladder guide groove 14
On stop slot point 15, to complete the adjustment of height and position.
Make the positioning end 31 from " E ＂ stop slots point 15 is slid on this of the top when pulling on the headrest bottom allotment 20
During end slot point 16 (as shown in Fig. 1, Fig. 5 position F), the positioning end 31 is by elastic properties of materials and directed along the ladder guide groove 14
It can slide down into the straight guide groove 12 of the master and sliding into and stop at lower end slot point 17 (as shown in Fig. 1, Fig. 5 position A)
On, the height and position of headrest 3 that can so carry out next time slides adjustment operation.
The present invention a kind of chair headrest lifting structure 1, with prior art such as compared with, there is advantages below：
(1), the lifting structure 1 of chair of the invention headrest is fixed by the lifting seat 10, the headrest bottom allotment 20 and the elasticity
