The structure of children's seat
As Fig. 1, Fig. 2, Fig. 5 and shown in Figure 6, children's seat 1 is provided with pair of armrests 10, this respectively has groove 104 to handrail 10 in its outside, and the upper surface of each handrail 10 has draw-in groove 101,102,103, in this embodiment, children's seat is a high chair, also can be other children's seat, for example perambulator or child safety seat etc.
The structure of service plate guiding mechanism
As Fig. 3 to shown in Figure 6, the service plate guiding mechanism comprise constitutes service plate 2 loam cake 21 with lower cover 22, reach actuator 23.
Loam cake 21 has corresponding shape with lower cover 22.Lower cover 22 has a plurality of buckling parts 2200, and loam cake also has corresponding a plurality of buckling parts (not shown)s.
As Fig. 4 and shown in Figure 6, two sides (top of lower cover 22 shown in Figure 4) have one respectively and are second chute 221 (vertical direction in Fig. 4 drawing) and a through hole 227 longitudinally about the surperficial thereon rear of lower cover 22, and port 227 is arranged in second chute 221.Moreover the surperficial thereon the place ahead of lower cover 22 centre (bottom of lower cover 22 shown in Figure 4) has recessed recess 226 downwards and is positioned at the opening 225 of recess 226 trailing flanks.In addition, lower cover 22 central longitudinal on surface thereon makes progress, and has first chute 223, teat 224 between second chute 223 and recess 226 at recess 226 rears and the stop section 222 that is positioned at first chute, 223 rears.
As shown in Figure 3, lower cover 22 has the corresponding slide 228 of a pair of and handrail 10 at its lower surface, and this respectively has the protruding rail 2281 corresponding with the groove 104 of handrail 10 to slide 228 in its relative inner.
As Fig. 4 and shown in Figure 6, in this embodiment, actuator 23 is the Y font, has the first cunning portion 233 that is hollow form in its front portion, from the second cunning portion 232 that the furcation 237 of the first cunning portion, 233 rear ends extends toward the left and right sides rear portion respectively and be positioned at press section 234 below the first cunning portion, 233 front ends.The first cunning portion 233 and the second cunning portion 232 correspond respectively to first chute 223 and second chute 221 of lower cover 22.Each second cunning portion 232 presents the ㄇ i section, is provided with the skewed slot 231 of a pair of correspondence at its left and right sides sidewall, is used for supporting slidably the fulcrum post 71 of locking piece 70.Be provided with fixed part 236 (see figure 7)s at the rear of the first cunning portion 233, be used for fixing an end of spring 60.Press section 234 extends back downwards then from the first cunning portion, 233 the place aheads.
The binding of children's seat and service plate guiding mechanism
Extremely shown in Figure 6 as Fig. 3, at first, the fulcrum post 71 of locking piece 70 is inserted in the skewed slot 231 of actuator 23, locking piece 70 is installed on the actuator 23 slidably, and between a primary importance and a second place, move, the first cunning portion 233 of again spring 60 being inserted is inner and make an end of spring 60 be fixed in the fixed part 236 of actuator 23, first chute 223 and second chute 221 that the first cunning portion 233 and the second cunning portion 232 of actuator 23 are inserted lower cover 22 respectively accordingly then, simultaneously, so that locking piece 70 is inserted in the through hole 227 of lower cover 22, make locking piece 70 bottoms protrude in the below of lower cover 22, the other end of spring 60 is resisted against the teat 224 of lower cover 22, and the press section 234 of actuator 23 is inserted in the recess 226 of lower cover 22 and from opening 225 and is extended for lower cover 22 belows, so that actuator 23 is installed on the lower cover 22 slidably, and vertically move along first chute 223 and second chute 221.As shown in Figure 4, at this moment, because the elastic force effect of spring 60, (in Fig. 4 drawing upward to) slides actuator 23 towards the rear with respect to lower cover 22, so that the furcation 237 of actuator 23 is resisted against the stop section 222 of lower cover 22, make locking piece towards primary importance.Then, loam cake 21 is covered on the lower cover 22, and makes the buckling parts (not shown) of loam cake 21 fasten accordingly or combine, finish the assembling of service plate 2 by fixture with the buckling parts 2200 of lower cover 22.
Then, this protruding rail 2281 to slide 228 of lower cover 22 lower surfaces is engaged in the groove 104 of the handrail 10 of children's seat 1 accordingly,, whereby, finishes the binding of children's seat and service plate guiding mechanism so that service plate 2 can move with respect to handrail 10.
The operation of service plate guiding mechanism
Fig. 7 to Figure 10 shows and adjusts service plate 2 and be positioned at schematic diagram with respect to the diverse location of handrail 10.
As shown in Figure 7, locking piece 70 is arranged in this primary importance and is sticked in the draw-in groove 101 of handrail 10 this moment, and this moment, service plate 2 was in position than the rear with respect to handrail 10.In the time of if service plate 2 will being moved to shown in Figure 9 position than the place ahead, as shown in Figure 8, push the press section 234 of actuator 23 towards the arrow P direction, at this moment, the fulcrum post 71 of locking piece 70 slides backward along skewed slot 231, so that locking piece 70 moves to the second place and breaks away from draw-in groove 101 from draw-in groove 101 on the direction shown in arrow U.Then, as shown in Figure 9, in the mode of the press section 234 that keeps pushing actuator 23, with service plate 2 to moving forward to position shown in Figure 9.Then, as shown in figure 10, discharge press section 234, actuator 23 moves towards the rear by the tension force of spring 60 so that fulcrum post 71 along skewed slot 231 to front slide, simultaneously locking piece 70 as shown by arrow D direction be displaced downwardly to primary importance and be sticked in the draw-in groove 102, or when service plate 2 reaches, decontrol the pressure part 234 of actuator 23, when locking piece 70 moved to draw-in groove 102, locking piece 70 can drop to primary importance automatically.By above operation, finish the position adjustment of service plate.
Similarly,, can implement above-mentioned identical operations, service plate 2 is moved forward to other draw-in groove section position with user's demand if service plate will be recalled to the position shown in Figure 7 or the another location in the place ahead more.
The person if will remove service plate 2 from handrail 10, needs only the press section 234 that actuator 23 is being pushed in maintenance in addition, pulls out service plate 2 forward and gets final product.
