Detailed description of the invention
Further describe the utility model below in conjunction with specific embodiments and the drawings, advantage and disadvantage of the present utility model will be more clear along with description.
As shown in Fig. 1 ~ 5, this is novel a kind ofly has the chair tool headrest 1 adjusting function up and down, and the shape of this headrest 1, is seen as an arc-shaped concave as shown in Figure 4, from horizontal cross shaft to being seen as an arc convex as shown in Figure 5 from vertical axial longitudinal up and down.
As shown in Figures 1 to 3, this headrest 1 is by sequentially comprising part 30 on rear side of front side member 10, middleware 20 and after forward direction, wherein, this front side member 10 and this middleware 20 are combined into one can synchronization-moving combination, wherein, the nearly corner place of this front side member 10 respectively establishes a button hole 11, as being provided with four button holes 11 in the illustrated embodiment of Fig. 1 ~ 2 but be not used to restriction this is novel.This middleware 20 is provided with the protruding fastener 21 with the corresponding fastening of button hole 11 of this front side member 10, the leading flank of this middleware 20 is provided with four protruding fasteners 21 but be not used to restriction this is novel as shown in Figure 2, and utilize this protruding fastener 21 respectively correspondence buckle in this button hole 11, can synchronization-moving combination to make this front side member 10 and this middleware 20 be combined into one, and borrow said structure design to make this front side member 10 and this middleware 20 can easyly complete in conjunction with assembling operation between the two.
This middleware 20 is provided with at least one Vertical dimension strip through hole 23, is provided with the two strip through holes 23 be arranged parallel to each other as shown in figures 2-3 but be not used to restriction this is novel in embodiment, be provided with again the microscler flange be parallel to each other for a pair along the both sides of this strip through hole 23 on the front surface of this middleware 20, a long guide channel 22 is formed between the microscler flange be parallel to each other to make two, recycling a guiding block 24 embeds in this long guide channel 22, and borrow locking part 25 such as locking screw that this guiding block 24 is passed through this strip through hole 23 with on the guide seat 32 of a correspondence on the front surface of locking part 30 on rear side of this, as shown in figures 2-3 in embodiment, namely two guiding blocks 24 are utilized to embed respectively on two guide seats 32 that in this long guide channel 22, also locking is corresponding on part 30 on rear side of this.
Again as shown in Figure 2, on rear side of this, the bottom of part 30 is provided with a connecting piece 31 for part on rear side of this 30 and whole headrest 1 being linked the top being located at the chair back of chair tool, do not limit as the structure of this chaining part 31, shape and/or the mode of connection between itself and the chair tool chair back, can use with reality and need and design for change, and due to this connecting piece 31 not this novel technical characteristic, therefore separately do not repeat at this.On rear side of this, the front surface of part 30 is provided with the guide seat 32 of at least one correspondence, be provided with two guide seats 32 as shown in Figure 2 in embodiment but be not used to restriction this is novel, this two guide seat 32 each tool certain altitude with must to embed in this long guide channel 22 for this guiding block 24 through this strip through hole 23 and locking on this guide seat 32; Wherein this guide seat 32 side place on the upper side, stage casing of being installed in the front surface of part 30 on rear side of this, to approximate or near the upper end of this strip through hole 23 and this long guide channel 22, now, this front side member 10 and this middleware 20 combine the combination (10,20) formed and be namely in the front initial state that adjusts not yet up and down as shown in Figure 3.
Again as shown in Figure 3, when user will carry out the adjustment up and down of resting the head on, this front side member 10 and this middleware 20 combine the combination (10 formed, 20) can be operated mobile as shown in arrow A in Fig. 3 upward, now this front side member 10 and this middleware 20 combine the combination (10 formed, 20) this guide channel 22 can be relied on to slide up and down relative to this guiding block 24 the relative of (i.e. rear side part 30) with this strip through hole 23, and adjusting upward of carrying out resting the head on, namely, this guiding block 24 remains on and to maintain static and this guide channel 22 and this strip through hole 23 produce relative movement, and when this front side member 10 and this middleware 20 combine the combination (10 formed, 20) when being adjusted upward to longitudinal higher position, namely this guiding block 24 is arranged in longitudinal lower position of this guide channel 22 and this strip through hole 23, in like manner, this front side member 10 and this middleware 20 combines the combination (10,20) formed and also can be adjusted downwardly to lower position, reach chair tool rest the head on 1 adjustment function up and down.
In addition, the groove width design of this guide channel 22 of the form fit of this guiding block 24, makes this guiding block 24 can embed in this long guide channel 22 and also must be formed and can close coordinating of smooth-going slip with the inwall of this long guide channel 22; Again this guiding block 24 can set up a hollow disc 241, must through the central authorities of this hollow disc 241 on the guide seat 32 of positioning locking correspondence of part 30 on rear side of this for this locking part 25, and this hollow disc 241 can be relied on further to reduce the friction between this guiding block 24 and this long guide channel 22 inwall, so can promote the smooth degree of relative sliding between the two, also enhancement adjusts the convenience of operation up and down relatively, and namely user can adjust the best use height of this headrest 1 to user pillow easily.
Above explanation and embodiment are only exemplary, do not form any restriction to scope of the present utility model.It will be understood by those skilled in the art that and do not departing under spirit and scope of the present utility model and can modify to the details of technical solutions of the utility model and form or replace, but these amendments and replacement all fall in protection domain of the present utility model.
