Detailed Description

In order to more clearly illustrate the embodiments of the present invention and the technical solutions in the prior art, the following description will refer to the accompanying drawings to describe specific embodiments of the present invention. It is to be understood that the drawings in the following description are merely exemplary of the invention and that other drawings and embodiments can be made by those skilled in the art without undue burden. The designation of the design orientation merely indicates the relative positional relationship between the respective members, not the absolute positional relationship.

The specific embodiment is as follows:

referring to fig. 1 to 5, the present embodiment provides a chair with a surrounding headrest, including a seat plate 1, legs 2 disposed below the seat plate 1, a backrest plate 3 disposed above the seat plate 1, a surrounding headrest 4 disposed above the backrest plate 3, and a support member 5 disposed on the backrest plate 3 for supporting the surrounding headrest 4.

Surrounding type headrest 4 can pass through support piece 5 fixed mounting in backup plate 3 top when people sit and have a rest on the chair, can lean on the head on surrounding type headrest 4, soft comfortable headrest can encircle in neck department, all plays certain supporting role to the back of the head and side, effectively promotes human comfort. But also feels a soft support of the wraparound headrest 4 even when the head is rotated or twisted.

In this embodiment, the support member 5 may include a support rod 501 disposed on the backup plate 3 and an arc-shaped cushion plate 502 disposed on the top of the support rod 501, and the surrounding headrest 4 is disposed above the arc-shaped cushion plate 502.

Specifically, the arc-shaped backing plate 502 can play a role of supporting the surrounding headrest 4, so as to prevent the surrounding headrest 4 from being crushed and deformed.

The surrounding headrest 4 and the arc-shaped backing plate 502 may be fixed by adhesion.

The arc-shaped cushion plate 502 can be a hard cushion plate, the binding force is large, and the headrest is more stable, such as a plastic cushion plate, a stainless steel cushion plate and the like.

The arc-shaped backing plate 502 can be an elastic backing plate, the binding force of the elastic backing plate is small, and the head can have a larger moving space.

When the head leans against the surrounding headrest 4, the experience of the human body is reduced in order to avoid the direct contact between the head and the arc-shaped backing plate 502. In this embodiment, the inner diameter of the arc-shaped backing plate 502 is greater than the inner diameter of the surrounding headrest 4, the outer diameter of the arc-shaped backing plate 502 is less than the outer diameter of the surrounding headrest 4, the radian of the arc-shaped backing plate 502 is less than the surrounding headrest 4, and the surrounding headrest 4 covers the arc-shaped backing plate 502. In this arrangement, when the head rests on the wraparound headrest 4, the head does not directly contact the arc plate 502 but is pressed against the arc plate 502 via the wraparound headrest 4.

Wherein, the radian of the arc-shaped backing plate 502 can be pi, and the radian of the surrounding headrest 4 can be 3/2 pi. The arc-shaped backing plate 502 is disposed coaxially with the wraparound headrest 4, so that the wraparound headrest 4 can be completely covered over the arc-shaped backing plate 502.

The smaller the radian of the arc-shaped base plate 502 is, the shorter the arc-shaped base plate 502 is, the smaller the stability of the surrounding type headrest 4 is, the headrest is easy to deform when leaning on the upper surface, but the limiting effect of the arc-shaped base plate 502 on the head is smaller, and the space in which the head can move is larger, so that the head can be freely twisted; the radian of arc backing plate 502 is bigger, arc backing plate 502 is longer, the stability of surrounding type headrest 4 is bigger, leans on above-mentioned the difficult deformation that takes place of headrest, but arc backing plate 502 is bigger to the limiting displacement that the head played for head activity space is less. Therefore, the radian of the arc-shaped backing plate 502 is not more than pi at most, so that the head of a human body can be easily separated from the surrounding type headrest 4 when the human body needs to stand up, and the arc-shaped backing plate 502 is prevented from generating a blocking effect on the head of the human body.

In addition, different people sit on the chair in different heights and different sitting postures, so that the height requirements of the headrest are different. When different persons sit on the same chair, the height of the headrest needs to be adjusted. In order to achieve the above purpose, in this embodiment, a cavity 6 is disposed inside the backup plate 3, the bottom end of the support rod 501 extends into the cavity 6, a limiting hole 503 is disposed on a side wall of the support rod 501, a fixing hole 504 is disposed on a side wall of the backup plate 3, the fixing hole 504 is communicated with the cavity 6, and the limiting hole 503 and the fixing hole 504 are fixed by a screw 505.

As shown in fig. 4, the left end of the screw 505 can pass through the fixing hole 504 and then be inserted into the limiting hole 503, so that the fixing hole 504 and the limiting hole 503 are relatively fixed, and the supporting rod 501 is relatively fixed.

Wherein, the bracing piece 501 lateral wall can be equipped with a plurality of not co-altitude positions spacing hole 503, will screw rod 505 is taken out behind the spacing hole 503, can be through will bracing piece 501 reciprocates, can be right the height of surrounding type headrest 4 is adjusted, will after the bracing piece 501 removes suitable high position, will again the screw rod 505 left end insert the correspondence in the spacing hole 503, can fix bracing piece 501 can satisfy the demand to the not co-altitude headrest.

A plurality of limiting holes 503 are uniformly distributed on the side wall of the supporting rod 501 along the vertical direction at intervals. The more the number and the more uniform the distribution of the limiting holes 503 are, the more the selectable height of the surrounding type headrest 4 is, and the wider the application range thereof is.

When the supporting rod 501 moves up and down, the supporting rod 501 may shake and shift, so that the limiting hole 503 and the fixing hole 504 cannot be aligned, and the left end of the screw rod 505 cannot be smoothly inserted into the limiting hole 503. In order to avoid the above phenomenon, in this embodiment, a snap ring 507 for limiting the support rod 501 is disposed in the cavity 6, and the snap ring 507 is fixedly mounted on the inner side wall of the cavity 6 through a connecting rod 508. By the arrangement, the supporting rod 501 can be kept vertical, and the supporting rod 501 is prevented from deviating.

When the chair is used, a person may press the chair, for example, if the surrounding headrest 4 is pressed, a downward pressure is generated on the support rod 501, which may cause the screw rod 505 to deflect downward, or even damage the screw rod 505. To avoid this phenomenon, in this embodiment, the limiting hole 503 penetrates through the left and right sidewalls of the supporting rod 501. The left end of the screw 505 can pass through the limiting hole 503.

The inner side wall of the cavity 6 is provided with a lapping table 506, and the left end of the screw rod 505 penetrates through the limiting hole 503 and is lapped on the lapping table 506. With the arrangement, the platform 506 supports the screw 505, so that the screw 505 is prevented from being inclined downwards or even damaged when the supporting rod 501 is stressed, and the service life of the chair can be prolonged.

The groove matched with the left end of the screw 505 can be formed in the lapping table 506, and the lapping stability of the screw 505 and the lapping table 506 is improved.

Finally, when the user does not need to use the headrest, the support rod 501 can be rotated by 180 °, so that the surrounding headrest 4 can be rotated to the back side of the chair, and the user can sit on the chair without being supported by the headrest.

The foregoing is a more detailed description of the invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended to limit the invention to the specific embodiments thereof. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, all should regard as belonging to the utility model discloses a protection scope.
