The specific embodiment

For the technology contents, the purpose that make the utility model use and the effect reached thereof have more complete and clearly disclose,, and see also disclosed diagram and figure number now in describing in detail down:

At first, see also Fig. 1 and Fig. 2 three-dimensional structure diagram of the present utility model and decomposing schematic representation, this chaise longue is mainly by back-rest 1, cushion portion 2, headrest portion 3 and arm-rest frame 4 constitute, its back-rest 1 two ends are articulated with headrest portion 3 and cushion portion 2 respectively, arm-rest frame 4 one ends of this chaise longue link by location-plate 11 and described back-rest 1 by a waist, be embedded in the chute 41 of arm-rest frame 4 other ends and organize the activity group 6 that is located at this cushion portion 2, and these back-rest 1 pivot connector occipitalia 3 places to waist is provided with a serial verb construction 5 by location-plate 11 places, incline to press down that the activity group 6 of interlock cushion portion 2 moves when lying in arm-rest frame 4 chutes 41 when back-rest 1, and the serial verb construction 5 of back-rest 1 drives headrest portion 3 perpendicular to back-rest 1, see also Fig. 6, this serial verb construction 5 includes:

One connecting rod 51, its correspondence are articulated on the lamellar body 31 of headrest portion 3 and the extension of back-rest 1 articulated section, are provided with a location slotted eye 511 in connecting rod 51;

One sleeve pipe 52, it is pivoted by location-plate 11 mutually with back-rest 1 waist, and described connecting rod 51 corresponding this sleeve pipe location that embed, these sleeve pipe 52 1 side respective link 51 location notch holes 511 places have extended sleeve 521, and correspondence is inserted ball 522, an elastic component 523 and a closure elements 524 to the ball 522 of pulling that can be limited in the location notch hole 511 in the sleeve 521.

See also the action schematic diagram of the headrest serial verb construction of Fig. 3 to Fig. 7 chaise longue of the present utility model, this chaise longue is when the normal sitting position state, as shown in Figure 3, the activity group 6 of this cushion portion 2 is positioned at the below of arm-rest frame 4 chutes 41, and should activity group 6 have locking and the function that unclasps, do not given unnecessary details structure in this, allow movable group 6 lockings be positioned at herein chute 41 positions, and the serial verb construction 5 of 3 in back-rest 1 and headrest portion, the balls 522 in this moment sleeve 521 are supported by elastic component 523 to pull and are embedded in the location notch hole 511 of connecting rod 51; When lying when desiring to incline, unclasping movable group 6 presses down back-rest 1 again, make its interlock cushion portion 2, allow movable group 6 in arm-rest frame 4 chutes 41, move to the top simultaneously, and press down because of back-rest 1, do not drive serial verb construction, therefore the connecting rod in the sleeve pipe 52 51 keeps identical corresponding length, and the ball 522 same inlay cards in the sleeve 521 are positioned at the location notch hole 511 of connecting rod 51, so that press down and headrest portion 3 can be toward top offset when back-rest 1, the state (as Fig. 4 and shown in Figure 6) that has angle with back-rest 1 formation, then, headrest portion 3 toward pressing down, so, is promptly changed the length that connecting rod 51 is positioned at sleeve pipe 52, allow connecting rod 51 pushing balls 522 slide simultaneously, ball 522 is slided to outside the location notch hole 511 of connecting rod 51, and at this moment, this headrest portion 3 can form the state of lying that inclines smoothly (as Fig. 5 and shown in Figure 7) with 1 of back-rest.
