Fig. 2 is the structural representation when collapsible elasticity bamboo chair is folding among Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the structural representation when collapsible elasticity bamboo chair is opened among better embodiment of the utility model, Fig. 2 is the structural representation of aforementioned collapsible elasticity bamboo chair when folding, in conjunction with Fig. 1 and Fig. 2 as can be known, this collapsible elasticity bamboo chair, comprise two back bracket 1, two left and right sides supports 2, two seat board supports 3, two underframe 6, wherein two left and right sides supports 2 articulate two back bracket 1 by screw 8 respectively, two seat board supports 3 articulate two left and right sides supports 2 by screw 8 respectively, two underframe 3 difference one ends connect back bracket 1, other end connecting base plate support 3.
The length of described back bracket 1 and shape can have multiple design and structure, for example at the top of back bracket 1 certain radian can be set backward, and head position was comfortable when such being designed with was beneficial to the user and rests on the chair.The length of back bracket 1 also can arrange different length according to the different demands of different occasions.
Be interval with the stull bamboo clappers 5 of 7 levels between the back bracket 1 from bottom to top, be equipped with the putting hole of stull bamboo clappers 5 terminations on the back bracket 1, stull bamboo clappers 5 can be in putting hole sliding extension.
The stull bamboo clappers of back bracket 1 support can arrange a plurality of according to actual needs, is generally 3-15.
Each stull bamboo clappers 5 consists of by two strip bamboo chips are laterally stacked at least, in the present embodiment, the strip bamboo chip that consists of the stull bamboo clappers of the top between the back bracket is 3, the strip bamboo chip that consists of other stull bamboo clappers between the back bracket is 2, the stull bamboo clappers bamboo chip of the top is greater than the effect that can play rock-steady structure of other parts herein, because may shelve head topmost, need larger ability to bear.
Bear maximum weight according to chair designs, select different strip bamboo chip thickness, the thickness of general every strip bamboo chip is the 1-10 millimeter, and the thickness of every strip bamboo chip is 5 millimeters in the preferred embodiment.
Each strip bamboo chip is for being that the vertical bar of bamboo of rectangle bonds side by side and consists of (being called for short the side pressure bamboo clappers), the medial surface of the vertical bar of each described bamboo and the vertical section that lateral surface is its employed mao bamboon by a plurality of cross sections.This structure, utilized the natural attribute of bamboo---in the situation that length is identical with cross section, the bamboo cane carrying puts on intensity and the toughness that the power on the vertical section shows, be better than its carrying and put on the outer surface of mao bamboon or intensity and the toughness that the power on the inner surface shows, common year force direction of bamboo chip turned round, and (this is optimal state to 90 degree, have the deviation that is not more than 30 degree during actual the use), this has just improved intensity and the toughness of strip bamboo chip.
The design of the stull bamboo clappers 5 of seat board support 3 supports is identical with the stull bamboo clappers 5 of backrest with the selection principle.
In the present embodiment, the two ends between the seat board support 3 are respectively equipped with a crosspiece 4, and crosspiece 4 is fixed on the seat board support 3 by screw 8.Be interval with the stull bamboo clappers 5 of 8 levels between the seat board support 3, the stull bamboo clappers that wherein consists of two ends between the seat board support is 4, and other stull bamboo clappers is 3 between the formation seat board support, and the thickness of every strip bamboo chip is 5 millimeters.Each strip bamboo chip is for being that the vertical bar of bamboo of rectangle bonds side by side and consists of the medial surface of the vertical bar of each described bamboo and the vertical section that lateral surface is its employed mao bamboon by a plurality of cross sections.
Be provided with two stulls 7 between the back bracket 1, be provided with a stull 7 between the left and right sides support 2, stull 7 can be used for the support between the support, is conducive to the Stability Analysis of Structures of whole folding seat.
Although the utility model discloses as above with preferred embodiment, the utility model is not to be defined in this.Any those skilled in the art within not breaking away from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with the claim limited range.
