Description

The angular adjustment apparatus of the headrest of wood chair

Technical field

The utility model is a kind of angular adjustment apparatus of headrest of wooden chair, belongs to the furniture technical field.

Background technology

The sofa that wooden chair is especially wooden has become the top grade in the furniture, and tracing it to its cause is that timber has belonged to the material of rareness, obtains difficultly, and making is taken a lot of work consuming time.Traditional essential chair is because properties of materials, Chang Wufa makes the movable adjustment function as other couch or skin chair, so that usually flow in fixing stiff profile, and have to come beautifying and decorating with some carved patterns, it is dumpable, then more rare to take the adjustment function such as the chair back that demand provides at human body for some.But existing in this technical field similar design as the headrest lifting structure of Taiwan notification number 484392 novel solid wood chairs, just provides a kind of wooden chair headrest of liftable height.As shown in Figure 1, this patented technology is to utilize two branch casings 31 to implant in the top cross bar 32 of the wooden chair back, and the head end of sleeve pipe 31 forms the screwed pipe 33 that splits; And two poles 35 that are placed through headrest 34 belows of wooden chair, but in these pole 35 threadings 31.And behind the height of determining headrest 34, rotate the nut 36 of screwed pipe 33 outsides, and make to screw tight this nut 36 and packing front support rod 35, reach the height of location headrest 34 and be suitable for abutting against of human body head.

The headrest lifting structure that the aforementioned patent case is provided makes originally, and stiff nonadjustable wooden chair becomes adjustable.But in the operating environment of reality, the chair back of wooden chair is done not only straight but also highly usually, and with Asians's stature, being sitting on the wooden chair its head, just to abut against in the chance of its headrest be very little, and the situations of the overwhelming majority are against head rest chair back face often; And the wooden chair back is harder again, original just difficultly makes the occupant obtain suitable sitting posture, more difficultly goes to require the occupant head abuts can be gone up and obtain comfortable support in headrest.

Summary of the invention

The utility model is to create a kind of new function on the headrest of traditional wooden chair, is that a kind of this headrest that makes rotates to adjust the design at the angle of depression, front and back, the elevation angle.A kind of luffing angle adjusting device of headrest promptly is provided, have one by the head lamp brush guard pivot device and down the pivot device inserted and put the device that is hinged to, wherein the head lamp brush guard pivot device is a  type shape, hinge is sandwiched in outside the following pivot device that is type shape.Connect a screw rod on the head lamp brush guard pivot device, connect a mast under the following pivot device, screw rod embeds in the headrest of wooden chair, mast then inserts in the cross bar on chair back top of wooden chair, this mast can also be provided with several grooves, to cooperate the locator of establishing in addition, makes headrest can carry out the location of lifting.The wherein side plate of the  type biside plate of head lamp brush guard pivot device forms a ridge, and forms a turning point on the side plate of the following pivot device of the same side.

After above-mentioned angular adjustment apparatus was installed in the chair back and headrest inside, the angle that headrest is bent forward and backward was turned; And hinge folder one check washer in addition between hinged of the side plate separately of upper and lower pivot device makes two pivot devices can obtain stable location after an angle is adjusted in rotation, and provides the weight of head abuts to support.By above-mentioned device, can provide the headrest of conventional wooden chair or head rest have can before the angle adjustment of bowing and swinging back, make head obtain best support.As for, the front side of headrest was located in the turning point of pivot device under this novel ridge that will resist the head lamp brush guard pivot device reached, be for the angle of bowing before the headrest is limited, this turning point also can be and is located at the dorsal part that is positioned at headrest symmetrically, elevation angle degree is limited after making headrest, novelly have the feature that to adjust any angle tool strong fix but weigh this, and it is very few generally headrest to be adjusted to the situation of full layback, so can not establish relative ridge and turning point at the rear side of resting the head on.

In sum, the utility model provide can before and after pitching adjust the headrest of the wooden chair of angle, wooden chair is had controls function more flexibly, and can arbitrarily angled adjustment and its wooden chair headrest of strong fix, so that the occupant obtains the head rest posture of the most comfortable.

The specific embodiment

As shown in Figure 2, the utility model provides a kind of device that makes wooden headrest make angle adjustment, and this device 10 is to comprise a head lamp brush guard pivot device 11 and pivot device 12 once, and head lamp brush guard pivot device 11 is a  type body, its top screw rod 13 that is spirally connected; Following pivot device 12 is a type body, and its bottom connects a mast 14, can be provided with several a detent (not shown) side or both sides on this mast 14 so that the lifting location of headrest to be provided, the setting of no any locating slot that also can be as shown in Figure 2.The biside plate 111 of head lamp brush guard pivot device 11 is biside plate 121 outsides that are folded in down pivot device 12, and makes it to be combined into one with the upper and

lower pivot device

11,12 of an axle 15 cross-under.Place a check washer 16 (as Fig. 5) in addition on biside plate 111,121 contact-making surfaces of upper and

lower pivot device

11,12, so that the strong fix after upper and

lower pivot device

11,12 rotates the adjustment angle mutually to be provided.Establish a ridge 112 and a turning point 122 on the wherein side plate 111,121 of upper and

lower pivot device

11,12 respectively, both can form clip after upper and

lower pivot device

11,12 rotates an angle, this ridge 112 and turning point 122 also can be located at the front and back end of side plate 111,121 simultaneously.

As Fig. 3～Fig. 5, this novel angular adjustment apparatus 10 is the headrests 21 that embed wooden chair with the screw rod 13 of head lamp brush guard pivot device 11, and the mast 14 of pivot device 12 is inserted in the chair back 22 upper ends of wooden chair down, and makes whole device 10 place a groove 211 of establishing in the headrest 21.Following pivot device 12 in this device 10 is inserted on the heavier chair back of wooden chair because of mast 14, head lamp brush guard pivot device 11 is inserted on the lighter headrest 21, head lamp brush guard pivot device 11 produces the rotation of pivot device 12 down with axle 15, headrest 21 can be turned its angle of depression and the elevation angle on the chair back 22, in this novel preferable enforcement structure, headrest 21 the angle of depression is because of the ridge 112 of head lamp brush guard pivot device 11 and the supporting to pull mutually and be restricted of turning point 122 of pivot device 12 down, ridge 112 and turning point 122 can be located at the same side or both sides, and make the angle of headrest 21 layback obtain restriction.But, even if the mutual clip with ridge 112 and turning point 122 does not limit headrest and luffing angle, groove 211 width (seeing it from Fig. 4) of excuse pillow 21 also make its luffing angle be detained to be limited to certain limit, do not have the rotation of excessive angle and cause neck injured.
