The specific embodiment

Below in conjunction with drawings and Examples, the utility model is elaborated:

For convenience of description, following embodiment, similarly element represents with identical label.Consult Fig. 2, Fig. 3, Fig. 4, first preferred embodiment of the utility model chair tool comprises: a chair frame unit 2, and a leaning unit 3 that is installed on this chair frame unit 2.

This chair frame unit 2 comprises one first chair frame 21 and one second chair frame 22 of making and being connected with stainless steel tube.This first chair frame 21 structure that takes the shape of the letter U, and have first cross bar 211, and two the first side levers 212 that backward extend on tiltedly from this first cross bar 211 respectively.In the present embodiment, described the first side lever 212 is respectively the expansion link of length Retractable.This second chair frame 22 structure that also takes the shape of the letter U, and have second cross bar 221, and two the second side levers 222 that extend forward on tiltedly from this second cross bar 221 respectively.Described the second side lever 222 is pivotally to be articulated in described the first side lever 212, and its length is less than the length of described the first side lever 212.

This leaning unit 3 comprises a ring frame 31, a cover cloth 32, a seating nettle 33, and several retaining elements 34.

This ring frame 31 of this preferred embodiment is that to be the stainless steel tube of annular made, and it is articulated in the apical margin of described the first side lever 212 and described the second side lever 222, and around defining space 310 in a ring.

This cover cloth 32 is to make with ventilative elastic woven material, and it is around being coated on this ring frame 31, and has on interior space 310 extensions of this ring and a slice separately cloth body 322 under cloth body 321 and a slice.Should match with this time cloth body 322 and be provided with a plurality of perforation 320 that run through up and down that distribute ringwise by upper cloth body 321.The quantity of described perforation 320 is corresponding to described retaining element 34, and in this preferred embodiment, described perforation 320 is respectively 16 with the number of described retaining element 34.

This seating nettle 33 is that the elastic threads braiding with elasticity extension power forms, it is installed on space 310 in this ring, and match with this cover cloth 32 and this ring frame 31 present discoid, this seating nettle 33 has a sitting part 331 that is netted and is applicable to take for human body, and quantity is corresponding to described perforation 320 and around the outer support part 332 of this sitting part 331.This sitting part 331 can by the elasticity power that extends, present zone line toward the shape (scheming not shown) of lower recess when grantee's body weight.Described outer support part 332 is to bury on this 322 of cloth bodies 321 and this time cloth body, and has respectively one and be subjected to face 333.

Described retaining element 34 is to be arranged in respectively the rivet of described perforation 320, and supports to arrive in respectively described outer support part 332, and this seating nettle 33 is combined with this cover cloth 32, and each retaining element 34 has the upper projecting face 341 of this ring frame 31 of vicinity.Described upper projecting face 341 can be distinguished contact described outer support part 332, for correspondence be subjected to face 333 respectively near.

This chair tool can be changed between a folded position and a non-folded position.

Consult Fig. 5, when this folded position, this first chair frame 21, this second chair frame 22 and this leaning unit 3 are and are arranged in parallel, described the first side lever 212 is to be reduced to the shortest length, described the second side lever 222 is that the pivot pendulum is to being parallel to described the first side lever 212, and this leaning unit 3 is to be in close proximity to described the first side lever 212 and described the second side lever 222, and this moment, this chair tool presented flat appearance, therefore was easy to take in.

Consult Fig. 2, Fig. 3, Fig. 4, when this non-folded position, this first chair frame 21 is tiltedly vertical respectively with this second chair frame 22, the length of described the first side lever 212 is extending, its apical margin can be higher than the apical margin of described the second side lever 222, and this leaning unit 3 is the tops that are positioned at this chair frame unit 2, and presents low early and high after angle of inclination, this moment, this seating nettle 33 can be taken for human body, and 31 of this ring frames can be for the neck of human body and hand by putting.

The utility model utilizes this cover cloth 32 and described retaining element 34 that this seating nettle 33 is incorporated into this ring frame 31 when making assembling, removes the shortcoming of sewing engineering method in the past from, has simplified work flow.When using, support to arrive in described outer support part 332 spacing by described retaining element 34, can avoid this

seating nettle

33 and 32 direct contact frictions of this cover cloth and cause breaking of this cover cloth 32, when not using, also this chair tool can be converted to this folded position to reduce volume from this non-folded position, the discoid profile of this leaning unit 3 also has the advantage of being convenient to take in.

Consult Fig. 6, Fig. 7, second preferred embodiment of the utility model chair tool, from aforementioned the first preferred embodiment different be in: described retaining element 34 defines respectively a cross-under passage 342, and described outer support part 332 is to pass respectively described cross-under passage 342 and the element 34 that is fixed supports to arrive in spacing.

This preferred embodiment discloses another kind of with the mode of this seating nettle 33 with these cover cloth 32 combinations, utilize the structure of described cross-under passage 342, described retaining element 34 can be with described outer support part 332 and this cover cloth 32 isolation, and when avoiding using, described outer support part 332 is stressed and pull this cover cloth 32, cause this cover cloth 32 to break.

Conclude above-mentionedly, no matter the utility model chair tool is the first preferred embodiment or the second preferred embodiment, all have the simplification manufacturing process, and the effect that can amount to, so really reached creation purpose of the present utility model.
