Description

Apparatus for adjusting angles of mat of baby's carriage

The utility model relates to a kind of setting device of perambulator seat cushion lying angle, particularly relates between a kind of framework and rod that is assembled in perambulator, but makes perambulator seat cushion multistage adjust the setting device of lying angle.

See also Fig. 1, it is a kind of schematic side view of perambulator in the past, perambulator 1 comprised a framework 11, two cooresponding rods 12 in the left and right sides and four and was assembled in the cooresponding wheel 13 in framework 11 bottoms all around in the past, this framework 11 comprises the skeleton 111 of position above wheel, on the skeleton 111 two of assemblings forward projection sit the make progress back stay 113 of projection of bar 112 and skeleton 111 rear sides, bar 112 is other to be provided with two handspikes of tiltedly stretching to the back upper place 114 sitting.This rod 12 is journaled into sits on the bar 112, rod 12 with sit on the bar 112 one of assembling and sit the seat cushion 2 of lying for the child, the dual-side of rod 12 extends the alar part 121 that company's edge is fixed on handspike 114 sides more respectively, the length of alar part 121 is greater than

rod

12 and 112 distances of handspike, thus both wing portions 23 can the bending hangings 114 of rod 12 and handspikes.

Please cooperate Fig. 2, it is the schematic perspective view of the setting device of perambulator seat cushion lying angle in the past, perambulator 1 can be adjusted for the lying angle that makes seat cushion 2 in the past, assemble a setting device 3 respectively at both

sides handspike

114 and 12 of homonymy rods, above-mentioned setting device 3 comprises a radius stay 31 that is fixed on rod 12 outer side edges, and a grab 32 that is hubbed on handspike 114 inboards, grab 32 trailing edges are provided with on the radius stay 31 that draw-in groove 321 can be fastened on homonymy.

When the child is sitting on the perambulator 1, the draw-in groove 321 of grab 32 is connected on the radius stay 31 in rod 12 outsides, because being subjected to the hook of two corresponding grabs 32 establishes, but rod 12 hangings are 113 of handspike 114 and back stays, and and sit bar 112 keep be a bit larger tham 90 the degree angles, for comfortable the taking of child.When the child is sleeping, will pull on two grabs 32, alar part 121 hangings are 114 of handspikes, make rod 12 and the clamping angle of sitting 112 on bar increases, and are fit to that the child is for sleeping in to lie.So perambulator 1 can only be adjusted two kinds of lying angles with grab 32 or two rods 12 of alar part 121 hangings, can't cooperate each child's actual needs in the past.

But the purpose of this utility model is to provide a kind of multistage to adjust perambulator and sits clamping angle between bar and rod, to improve the lying angle setting device of seat cushion comfort.

The utility model provides a kind of setting device of perambulator seat cushion lying angle, the rod that this perambulator comprises framework and is located at the perambulator both sides, each rod is to be articulated on the framework, and the other end can move with respect to this framework, between two rods, be connected with the seat cushion of perambulator, this setting device is to make the relative framework of the rod other end be assembled in the both sides of perambulator movably, wherein, each setting device all comprises a connector bushing and adjustment plate of mutual socket, and connector bushing then is articulated on stroller frames and the rod respectively with an end of adjusting the relative socket end of plate; Connector bushing is being provided with a passage with adjusting on the end that sleeve-board connects, adjusting sleeve-board is connected in this passage, connector bushing is provided with a positioning groove that occurs simultaneously, communicates with passage, control seat of assembling in this positioning groove, support a spring between positioning groove and control seat, the passage that control seat is provided with one and connector bushing is the cooresponding groove of wearing laterally, on the control seat in wearing groove a distal process go out a clamping block; A side of adjusting the corresponding control seat clamping block of plate is provided with a plurality of draw-in grooves.

In the utility model, utilize a control seat to adjust two connector bushings that socket-connect and adjust socket length between plate, the aforementioned connector bushing that socket-connects is located on stroller frames and the rod with the support of adjustment plate, utilize the variation of socket length between aforementioned connector bushing and adjustment plate, change abutment pad stack-mounted rod and framework are sat the clamping angle between bar, and the lying angle of perambulator seat cushion can be adjusted on multistage ground.

Setting device of the present utility model is the dual-side that is assembled in stroller frames accordingly, each setting device all comprises a connector bushing, connector bushing one end is hubbed on the rod of perambulator, the other end forms a horizontal passage, the adjustment plate of a slip of socket in this passage, adjustment plate not socket one end then is fixed on the framework of perambulator, one and passage common factor are set on connector bushing again, the positioning groove of conducting, control seat that shored by spring of assembling in the positioning groove, control seat is provided with one and wears groove with passage is conducted, wear bottom land side plate inner body surface and be provided with a clamping block, adjust the corresponding clamping block of plate position and form a plurality of draw-in grooves.When clamping block on the corresponding control seat that is assembled in the perambulator both sides is fastened on homonymy respectively when adjusting on the plate on one of them draw-in groove, can make between the socket length after the socket certain, and make that the abutment cushion cover establishes to sit between bar and rod the clamping angle certain.When in interior pressure-controlled seat makes clamping block on the pedestal, moving, adjusting plate can slippage in the passage of connector bushing, to change connector bushing and the length of adjusting after the plate socket, just can change rod and sit clamping angle between bar, make the lying angle of perambulator seat cushion can the adjustment of multistage ground.
