Detailed Description
The present invention will be described in further detail with reference to the following examples and the accompanying drawings.
Fig. 1 and fig. 2 show a first embodiment of the present invention. Comprises a chair backrest 1 and a headrest fixing frame 2 fixed on the chair backrest 1, wherein a left rotating shaft 3 and a right rotating shaft 4 are fixedly arranged on the headrest fixing frame 2, a left headrest soft roller 31 which can rotate freely is arranged on the left rotating shaft 3, a right headrest soft roller 41 which can rotate freely is arranged on the right rotating shaft 4, the left soft headrest roller 31 (axis) and the right soft headrest roller 41 (axis) are positioned in the same plane, the left soft headrest roller 31 and the right soft headrest roller 41 are arranged in parallel, the left soft headrest roller 31 and the right soft headrest roller 41 are positioned in the area of the hindbrain of a human body, the interval distance between the left soft headrest roller 31 and the right soft headrest roller 41 is 8-28 cm, the value is an empirical value, and may be set according to actual needs, that is, the head of a person is just clamped between the left headrest soft roller 31 and the right headrest soft roller 41. The diameter of the left headrest soft roller and the diameter of the right headrest soft roller are both larger than 5cm, the values are empirical values and can be set according to actual needs, the outer layers of the rollers are wrapped by soft materials such as cellucotton and the like, so that the head of a person feels comfortable, the contact area between the rollers and the head can be increased by slightly increasing the diameters of the rollers, and the head of the person also feels comfortable. So, the chair headrest by left headrest soft roller 31 with right headrest soft roller 41 constitutes, and human head is in left headrest soft roller 31 with between the right headrest soft roller 41, no matter be human head to which orientation deflection, because left headrest soft roller 31 with right headrest soft roller 41 can rotate in a flexible way, human head can not roll and go out more left headrest soft roller 31 with between the right headrest soft roller 41, do not have other inertial force or the effect of external force down the head gravity make the focus of head remain all the time left headrest soft roller with between the right headrest soft roller. Therefore, when a person sits on the backrest chair for a long time to sleep and rest, the head of the person is always kept right above the neck of the person on the headrest of the invention, and the person cannot lean to one side of the body to cause neck ache. The left and right soft- headrest rollers 31 and 41 may be cylindrical rollers or spherical rollers. Of course, most of the headrest fixing frames 2 of the chairs can move up and down, so that the left headrest soft roller 31 and the right headrest soft roller 41 of the invention can actually move up and down along with the headrest soft roller, thereby better adapting to the requirements of different human bodies.
Fig. 3 and 4 show a second embodiment of the present invention. In the second embodiment of the present invention, on the basis of the first embodiment, headrest cushions 5 are disposed at the rear portions of the left headrest soft roller 31 and the right headrest soft roller 41. An appropriate distance can be arranged between the headrest cushion 5 and the left headrest soft roller 31 and the right headrest soft roller 41, so that three points of the head of a human body can be contacted with attachments, and the head of the human body can stably and comfortably lean between the left headrest soft roller 31 and the right headrest soft roller 41.
Fig. 5 and 6 show a third embodiment of the present invention. Different from the first embodiment, a transverse supporting shaft 6 is arranged on the extending portion 21 of the headrest fixing frame 2, a support 7 is movably fixed on the supporting shaft 6, the support 7 is a rectangular frame, the upper frame 71 of the rectangular frame support 7 is respectively provided with a plurality of upper open slots 711, the lower frame 72 of the rectangular frame support 7 is respectively provided with a plurality of lower open slots 721, the left rotating shaft 3 and the right rotating shaft 4 can be movably fixed on the upper slots 711 and the lower slots 721, and the support 7 can rotate around the supporting shaft 6. Therefore, the left soft headrest roller 31 and the right soft headrest roller 41 can be fixedly placed in different slotted holes according to requirements, and the distance between the left soft headrest roller 31 and the right soft headrest roller 41 can be adjusted at will to meet the requirements of different people; meanwhile, the bracket 7 can rotate around the supporting shaft 6 to meet the requirement of human head pitching, so that the human head feels more comfortable. The left and right soft- headrest rollers 31 and 41 may be cylindrical rollers or spherical rollers. Of course, most of the headrest fixing frames 2 of the chairs can move up and down, so that the left headrest soft roller 31 and the right headrest soft roller 41 of the present invention can actually move up and down along with the headrest soft roller, so as to better adapt to the needs of different human bodies, or the bracket 7 of the present embodiment is designed to be a mechanism capable of moving up and down, which is also easy to be realized by those skilled in the art.
Fig. 7 shows a fourth embodiment of the present invention. Different from the third embodiment, the bracket 7 is an arc-shaped frame, and a plurality of left headrest soft rollers 31 and a plurality of right headrest soft rollers 41 are arranged on the arc-shaped frame bracket 7, wherein three left headrest soft rollers 31 and three right headrest soft rollers 41 are shown in the figure. Thus, the head 8 can be limited and supported by the soft rollers, so that the head of a human body is less prone to laterally deflecting, and the head of the human body feels more comfortable. Of course, the diameters of the left and right soft-head rollers in the present embodiment may not be limited to be larger than 5cm, but may also be smaller than 5cm, because the soft roller increases the contact surface with the human head, the diameter of the roller may be reduced appropriately.
Fig. 8 shows a fifth embodiment of the present invention. Different from the above embodiments, in this embodiment, the left turning shaft device and the right turning shaft device in the above embodiments are changed from a single left headrest soft roller and a single right headrest soft roller into a left turning wheel group and a right turning wheel group, both the left turning wheel group and the right turning wheel group are composed of a plurality of turning wheels, and the arrangement shapes of the plurality of turning wheels of the left turning wheel group and the right turning wheel group in fig. 8 are all in the shape of a quarter arc; the left rotating wheel set and the right rotating wheel set are in a splayed shape.
Fig. 9, fig. 10 and fig. 11 show a sixth embodiment of the present invention. On the basis of the fifth embodiment, the arrangement shapes of the plurality of rotating wheels of the left rotating wheel set and the right rotating wheel set in the figures 9 and 10 are circular. A left soft rotating belt 9 is arranged on the outer surface of the left rotating wheel set; the right rotating wheel set is also provided with a right soft rotating belt 10 as the left rotating wheel set. Thus, the comfort and the aesthetic property can be greatly improved. In a further form, the arrangement of the plurality of wheels of the left and right wheel sets is fan-shaped as shown in fig. 11, but may be any other shape, such as an ellipse.
Fig. 12 shows a seventh embodiment of the present invention. On the basis of the sixth embodiment, a middle rotating wheel set is arranged in the center of the left rotating wheel set and the right rotating wheel set, so that the comfort is greatly improved.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
