Detailed description of the invention
For making the utility model definitely full and accurate, hereby enumerating preferred embodiment and coordinating following schemes, structure of the present utility model and technical characteristic thereof are described in detail as rear:
Direction mentioned in this description, if "front", "rear", "left", "right" etc. are all correspond to user's direction cognition in a state of use.
As shown in Figures 1 to 5, back structure of the present utility model is integrated structure, comprises base 10 and a chair back 20.
This base 10 is formed as being incorporated into a seat support 30, and this base 10 is provided with multiple for the slotted eye 11 that combine corresponding to this seat.This base 10 can be sharp made of plastic.
This chair back 20 upwards extends from the side of this base 10 and is formed as the chair back of saddle.The shape of this chair back 10, be seen as a concave surface (as shown in Figure 5) from seat support 30 vertical axial, the horizontal axis above seat support 30 is seen as a convex surface (as shown in Figure 4).This chair back 20 includes chair back frame portion 21 and backrest face 22, and this backrest face 22 side in this chair back frame portion 21 extends and is staggered to form as network structure.This chair back 20 selects the plastics with this base 10 same material, and make in one-body molded mode with this base 10, namely, the chair back frame portion 21 of this base 10 and this chair back 20 and backrest face 22 integrated formations, and the side of chair back frame portion 21 on the leading flank of this chair back 20 and backrest face 22 is continuous print the same face.Above-mentioned backrest face 22 can be the network structure that horizontal and longitudinal cross arrangement is formed, but not as limit, as the network structure that diagonal cross arrangement is formed, or in honey comb like network structure, aforesaid network structure can be the network structure of equidistant evenly distributed formation or the network structure of Unequal distance uneven arrangement formation.Another according to using needs, the thickness in the chair back frame portion 21 of this chair back 20 can select the thickness being greater than backrest face 22, but not as limit, the thickness as chair back frame portion 21 selects the thickness equaling backrest face 22.As shown in Figure 6, the backrest face 22 of this chair back 20 is also provided with at least one pattern area 23 for can be used for being expressed as predetermined or relevant word or figure, wherein, this pattern area 23 is made into integration with the network structure of this backrest face 22, and the surface energy of this pattern area 23 is protruded, recessed or flush mesh 221 set on aforesaid network structure.
As shown in Figure 1, the space 24 that one runs through base 10 and the chair back 20 is provided with between this base 10 and this chair back 20, in figure, this space 24 is positioned at the lower end in the chair back frame portion 21 of this chair back 20, and rely on this space 24 structure to reduce material usage, and therefore overall weight alleviates, can also at this chair back 20 by abutting against during pressurized, effect that can promote flexural buckling is provided.
