The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is the dining chair schematic diagram that is equiped with the utility model backrest guiding mechanism, this dining chair mainly includes preceding foot rest 4, rear leg 5, seat support, is connected the service plate 6 that can realize forward and backward adjustment on the seat support respectively, wherein seat support comprises the seat storehouse 3 and the backrest 1 of mutual pivot joint, and is provided with backrest guiding mechanism of the present utility model between seat storehouse 3 and the backrest 1.
Again in conjunction with shown in Figure 2, backrest guiding mechanism of the present utility model except described seat storehouse 3 and backrest 1, the actuation means 2 that also include a bracing frame 7, is constituted by operating parts 21 and spring 24 etc. etc., wherein:
Seat storehouse 3 has two handrail shape projectioies in the both sides that are positioned at backrest 1 rear portion, be respectively equipped with a circular groove 8 on the projection, all correspondence is provided with a plurality of stopper slots 81 (as shown in Figure 5) for the insertion of bracing frame 7 two ends in groove 8, and the two ends 71 of bracing frame 7 are inserted in the different stopper slot 81,82 and make backrest have different angles of inclination.The design of present embodiment seat storehouse has four stopper slots 81,82, thereby make backrest 1 can realize the fourth gear angle adjustment, but third gear is for being fit to the backrest angle that baby child takes wherein, and last step is only designed for packing, when backrest 1 is adjusted to this grade, it is in a straight line substantially with seat storehouse 3, and volume reduces greatly after whole dining chair folds like this, is beneficial to packed and transported and deposits.
The bottom of backrest 1 is articulated in by pivot with seat storehouse 3, be provided with two gathering sills 11 that can supply screw to pass in the middle part on backrest 1 top, on the upper and lower position between two grooves, be respectively equipped with spacing preiection 29 and limited block 23, wherein spacing preiection 29 matches with the stroke of two gathering sills 11, is used to limit the stroke that moves on the operating parts.Limited block 23 is to be used to limit the stroke that operating parts moves down, because the fourth speed stopper slot 82 in this storehouse is only designed for packing, it is not suitable for taking of baby child.Therefore consider from security standpoint that for fear of user's maloperation, when backrest angle was transferred to third gear, limited block 23 can limit operating parts and continue pulling.This limited block 23 comprises spacing rib 231 and in order to drive the elastic button 232 (as shown in Figure 3) of this spacing rib action, this elastic button 232 also is the guiding projection that can insert in the operating parts chute, and it utilizes the elasticity of plastic cement can press down and elastic recovery.If backrest will be adjusted to fourth speed, must press this elastic button 232, eliminate the restriction of 23 pairs of operating parts of limited block, make operating parts can continue pulling.In addition also be formed separately a plurality of demihull shape projectioies 83, and on projection 83, be equipped with a perforation, can pass in regular turn, to play the effect of and guiding spacing bracing frame 7 for the both ends of bracing frame 7 in the both sides of backrest 1.And perforation is arranged on the demihull shape projection 83, can guarantee the intensity of boring a hole.
Actuation means 2 slidably is arranged at backrest 1 back, it mainly comprises an operating parts 21, a spring 24 and two screws 22 that play connection and guide effect, wherein operating parts 21 is designed to be beneficial to the case shape that hand grips, and its bottom, back that is connected with backrest 1 fits with backrest 1 and slippage up and down.With reference to figure 4, this operating parts 21 is provided with the screw 25 that two screws 22 connect usefulness, with a chute 27 that can supply the elastic button 232 on the backrest 1 to insert, and the ccontaining breach 28 that can supply bracing frame 7 to wear, and be provided with spring base 26 in its inside and constitute spacing position limiting structure with spacing preiection 29 and limited block 23 on the backrest 1, as shown in Figure 4.
When this actuation means 2 is assembled mutually with backrest 1, earlier spring is positioned in the spring base 26 of operating parts, and the elastic button 232 on the backrest is inserted in the chute 27 of operating parts 21, then two ccontaining breach 28 correspondences on the operating parts 21 are covered on bracing frame 7, linking with operating parts 21 with two screws 22 that pass the gathering sill 11 on the backrest gets final product again, and assembles very convenient.
With reference to figure 6, Fig. 7 and Fig. 8, under the normal condition, elastic button 232 is positioned at the chute 27 of operating parts, realize the angular adjustment of three gears, specific as follows: pull operation part 21 makes progress, driving bracing frame 7 by operating parts 21 moves upward, make the two ends 71 of bracing frame leave stopper slot 81 on the storehouse 3 respectively, this moment, rotatable backrest 1 was made angle adjustment, when adjusting to another gear, operating parts 21 inserts in another stopper slot 81 in seat storehouse 3 two ends 71 of bracing frame 7 heavily again under the rebound effect of spring 24, thereby realize the order of angle adjustment, its state such as Figure 10 are to shown in Figure 13.
When needs are packed up dining chair and are packed or store, as long as push elastic button 232 downwards, move downward by these elastic button 232 interlocked limited ribs 231, releasing is bumped to spacing operating parts 21, makes operating parts 21 can continue downward pulling, and backrest 1 is adjusted to tail shelves 82 (being fourth speed), this moment, backrest 1 roughly was a straight line (with reference to figure 9) with seat storehouse 3, after the more preceding foot rest 4 of dining chair and rear leg 5 etc. being folded, the volume in the time of can making packing or storage reduces greatly, as shown in figure 14.
