Detailed description of the invention
For making the utility model definitely full and accurate, hereby enumerating preferred embodiment and coordinating following schemes, structure of the present utility model and technical characteristic thereof are described in detail as rear:
Fig. 1 is that the utility model chair tool is rested the head on the stereoscopic figure of upper and lower adjust structure.Fig. 2 is the top view of Fig. 1.Fig. 3 is the side view of Fig. 1.Fig. 4 is a three-dimensional exploded view of the present utility model.Fig. 5 represents three-dimensional exploded view of the present utility model in more detail according to Fig. 4 content.
As shown in Figures 1 to 5, the utility model provides a kind of chair tool to rest the head on upper and lower adjust structure, and it comprises a headrest 10, and this headrest 10 is the tops relying on a pin connected assembly 20 to be arranged on chair back (not shown).The shape of this headrest 10, from upper and lower longitudinal direction depending on be a concave surface (as shown in Figure 2) to human body, be then convex surface (as shown in Figure 3) viewed from horizontal transverse direction.This headrest 10 comprises front side member 11, intermediate member 12 and a rear-side member 13, and this intermediate member 12 is located between this front side member 11 and this rear-side member 13.This front side member 11 is provided with at least two spaced holding sections 111, and each holding section 111 can be but is not limited to runs through through hole.This intermediate member 12 is provided with the engaged part 121 that at least two corresponding holding sections 111 engage, and each engaged part 121 can be but not be limited to projection.This front side member 11 is combined into one after mutually being engaged with engaged part 121 by holding section 111 with this intermediate member 12, and relatively this rear-side member 13 longitudinally can move up and down displacement.As shown in Figure 4, each holding section 111 includes through hole 112, and the edge of this through hole 112 is provided with at least one groove 113; Each engaged part 121 includes projection 122, this projection 122 be provided with at least one can with the projection 123 of the mutual snapping of described groove 113.When holding section 111 engages mutually with engaged part 121, the projection 123 of projection 122 fastens mutually with the groove 113 of through hole 112.Wherein, protruding 123 is flexibly be fastened in groove 113.
A damping mechanism 40 is also provided with between this intermediate member 12 and this rear-side member 13, this damping mechanism 40 is suitable for providing a cushioned resistance when this front side member 11 and this intermediate member 12 this rear-side member 13 relative move up and down displacement, and promotes the stability of its moving displacement.This damping mechanism 40 comprises at least two damping wheel 41 and at least two tooth bars 42, each damping wheel 41 and each tooth bar 42 toe joint mutually, as Fig. 4, in example shown in Fig. 5, this at least two damping wheel 41 is left, be arranged on this intermediate member 12 towards in the one side of this rear-side member 13 right septum, this at least two tooth bar 42 to should at least two damping wheels 41 longitudinally and be arranged on this rear-side member 13 abreast towards in the one side of this intermediate member 12, but, in this non-limiting example, in meaning of the present utility model, damping wheel 41 can exchange with the setting position of tooth bar 42, therefore, the damping produced in this way, and activated drive is on this front side member 11 of operation and this intermediate member 12 this rear-side member 13 relative, during lower moving displacement, this front side member 11 and this intermediate member 12 this rear-side member 13 displacement height relative is adjusted by means of helping operation more intuitively, namely reach the height of this headrest 10 of adjustment for user's pillow.
Again, a guiding position-limit mechanism 50 is also provided with between this intermediate member 12 and this rear-side member 13, this guiding position-limit mechanism 50 is suitable for providing a guiding limit effect when this front side member 11 and this intermediate member 12 this rear-side member 13 relative move up and down displacement, and promotes correctness and the security of its moving displacement.This guiding position-limit mechanism 50 comprises at least two locating piece 51 and at least two strip holes 52, locating piece 51 is by strip hole 52 and can along the length direction relative displacement of strip hole 52, as Fig. 4, in embodiment shown in Fig. 5, this at least two locating piece 51 is left, be arranged on this rear-side member 13 towards in the one side of this intermediate member 12 right septum, this at least two strip hole 52 to should at least two locating pieces 51 longitudinally and be arranged on this intermediate member 12 abreast, but, in this non-limiting example, in meaning of the present utility model, locating piece 51 can exchange with the setting position of strip hole 52, therefore, the guiding limit effect produced in this way, and activated drive is on this front side member 11 of operation and this intermediate member 12 this rear-side member 13 relative, during lower moving displacement, by means of helping more correctly, more safely this front side member 11 of operation adjustment and this intermediate member 12 this rear-side member 13 displacement height relative, namely reach the height of this headrest 10 of adjustment for user's pillow.
The content of guiding position-limit mechanism is disclosed according to the utility model, in order to promote the stability of locating piece 51 in strip hole 52 during displacement, this guiding position-limit mechanism 50 comprises at least one align member 53 further, this align member 53 is configured in contrast to the opposite side of locating piece 51 at strip hole 52, align member 53 and locating piece 51 also utilize a connection piece 54 align member 53 and locating piece 51 to be linked together, in embodiment as shown in Figures 4 and 5, align member 53 and locating piece 51 are configured at the contrary both sides of strip hole 52 respectively and form sandwiched kenel.So, when operating this front side member 11 and relative this rear-side member 13 displacement height of this intermediate member 12, by means of the combination of align member 53 with locating piece 51, locating piece 51 more stably can be moved during displacement in strip hole 52, namely reach the stability promoting this headrest 10 displacement height movement of adjustment.
The content of front side member and intermediate member is disclosed according to the utility model, when front side member 11 being arranged the bolster (not shown) for user's head pillow, this front side member 11 relies on the groove 113 on the through hole 112 of each holding section 111 with this intermediate member 12, and the projection 123 on the projection 122 of each engaged part 121, this front side member 11 and the assembling of this intermediate member 12 can be made to become easier, and the setting of above-mentioned bolster can not be subject to and affect the assembling of this front side member 11 and this intermediate member 12.
From above-mentioned implementation, the utility model and prior art are compared down, and the utility model has the following advantages:
The utility model relies on damping mechanism and guiding position-limit mechanism with when adjustment of resting the head on moves up and down, a cushioned resistance and one can be provided respectively to guide limit effect, allow user when operation adjustment headrest moves up and down, stability and security can be promoted, and the unlikely situation that vibration and double swerve occur.
More than illustrate the utility model just illustrative; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claim limits; many amendments, change or equivalence can be made, but all will fall within protection domain of the present utility model.
