Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.

A kind of folding chaise longue as shown in Fig. 1 ~ 3, by the support body 1 of inside, and is coated on the sponge obturator 2 outside support body 1, and the overcoat 3 be coated on outside sponge obturator 2 is formed.Namely this folding chaise longue is by simplifying structure, is all dispensed by the holding components of traditional Folding deck chair lower end, only leaves the chair surface structure of traditional Folding deck chair, weight reduction, be convenient for carrying and receive.

Support body 1 is made up of seat of honour bar 11, counter-base bar 12, back of the body bar 13 and angle demodulator 3.The front projection of seat of honour bar 11 is opening U-shape backwards, seat of honour bar 11 is is integrally connected and composed by the connecting rod 112 of two swing arms be arranged in parallel 111 and connection two swing arm 111 leading sections, the cross section of swing arm 111 is the high circular arcs in two ends at the bottom of middle part, seat of honour bar 11 is along bottom surface, the middle part swing of swing arm 111, namely whole Folding deck chair can be carried out swing along its lower surface, be similar to rocking chair, comfort is good.The front projection of counter-base bar 12 is opening U-shape forward, and counter-base bar 12 is in the U-shaped opening inner side of seat of honour bar 11, and two free ends of counter-base bar 12 are separately positioned on two swing arm 111 medial surfaces of seat of honour bar 11.The front projection of described back of the body bar 13 is opening U-shape forward, two free ends of back of the body bar 13 are all hinged in the rearward end of two swing arms 111 of seat of honour bar 11 by angle demodulator 3 respectively, the longitudinal length A of seat of honour bar 11 is 1.7 ~ 2.3 times of back of the body bar 13 longitudinal length B, and then the weight defining seat support is far away higher than the weight of the chair back, prevents whole chaise longue hypsokinesis.

As shown in Figure 4, angle demodulator 3 comprises the first connector 31 and the second connector 32, first connector 31 is hinged by bearing pin a and the second connector 32.The first Access Division 312 that first connector 31 comprises the first socket part 311 and is connected with the first socket part 311 one.First Access Division 312 is hinged with ratchet 33 by bearing pin b, ratchet 33 is provided with for the torsional spring slot 331 for placing torsion spring, be provided with torsion spring 34 in torsional spring slot, the middle part of torsion spring 34 is set on bearing pin b, and two free ends of torsion spring 34 are stuck on the inner end of the first socket part 311 respectively.The second Access Division 322 that second connector 32 comprises the second socket part 321 and is connected with the second socket part 321 one.Second Access Division 322 is provided with the block 35 and multiple unidirectional gear teeth 36 that are connected as a single entity with it, multiple unidirectional gear teeth 36 are arranged along the inner end edges rule of the second Access Division 322, and forming the wheel flank of tooth each other, the wheel flank of tooth that the inner end of ratchet 33 and the unidirectional gear teeth 36 are formed offsets formation ratchet wheel positioning mechanism.Second Access Division 322 is also coaxially arranged with spacer 37 along bearing pin a, described spacer 37 comprises outside cambered surface diameter and is greater than the location division that the reset portion 371 of the wheel flank of tooth and outside cambered surface diameter be less than the wheel flank of tooth, location division is provided with locating aperture 372, and block 35 is in locating aperture 372.When spacer 37 rotates along bearing pin a, reset portion 371 and ratchet 33 offset, are rotatably assorted, and locating aperture 372 and block 35 are rotatably assorted.

During use, the first socket part 311 on first connector 31 is socketed in swing arm rearward end, the second socket part 321 on second connector 32 is socketed on back of the body bar free end, the ratchet wheel positioning mechanism formed due to inner end and the unidirectional gear teeth 36 of ratchet 33 can only the clockwise one-directional rotation of the chair back, therefore the angle between seat support and the chair back is turned down, can regulate step by step according to the unidirectional gear teeth 36, be taken to user by adjusting back.And the angle between seat support and the chair back is when being less than certain angle, block 35 on second connector 32 promotes locating aperture 372 right side wall of spacer 37, spacer 37 is rotated clockwise along bearing pin a, the reset portion 371 of spacer 37 offsets with the inner end of ratchet 33, extrudes, because the outside cambered surface diameter of reset portion 371 is greater than the wheel flank of tooth, therefore, while reset portion 371 and ratchet 33 offset, ratchet 33 and engaging between the unidirectional gear teeth 36 is removed; Now, the chair back can be able to be overlayed on seat support on the one hand, convenient for collecting; Angle between seat support and the chair back can be tuned up on the other hand, because the reset portion of spacer 37 371 and ratchet 33 offset, remove ratchet 33 and engaging between the unidirectional gear teeth 36; When second connector 32 and upper fixed stop 35 thereof are rotated counterclockwise, spacer 37 and ratchet 33 offset and thus do not rotate, until after block 35 and the left side wall on spacer 37 offset, block 35 promotes spacer 37 and rotates counterclockwise until spacer 37 departs from ratchet 33, ratchet 33 the inner is engaged with the unidirectional gear teeth 36 again, and chair back expanded angle is maximum.
