One, when leisure chaise longue was used in use always, if the sitting posture pattern will be changed into the lying posture pattern, the user must leave leisure chaise longue earlier, again tenon and draw-in groove was reorientated adjustment chair back angle, just caused the inconvenience in the use thus.

Two, because leisure chaise longue commonly used is to utilize tenon and draw-in groove to cooperate to reach the adjustment function, the yardstick of its adjustment then is subjected to the draw-in groove length restriction, the chair back angle that sets out can't the person's of being used body angle, so when user's seat lies on the leisure chaise longue, can't provide user's health good suitable support effect, easily cause leisure seat in user's waist territory to form vacant state, after growing slightly between causing in use, just feel the situation of having a pain in the back not reach the requirement of real comfortableness.

Three, the structural design of leisure chaise longue commonly used allows user's shank and sole hang on ground, if this mode can not produce sticky feeling during sitting posture, if but during lying posture this design can make shank produce constriction, can't loosen quiet and comfortablely at all and have a rest.

In view of above-mentioned every use disappearance, the purpose of this utility model is manufacturing and designing the leisure chaise longue that overcomes above-mentioned shortcoming.

The utility model is a kind of leisure chaise longue structural improvement, this leisure chaise longue structure sets firmly meter by the pivot of trapezium bar linkage structure, make and have the strength size that to lie backward according to the user between its chair back and the pedal and the function of indexing, so when the user desires to become lying posture with this creation by sitting posture, can be directly rearward one lie and to allow leisure chaise longue be the lying posture kenel, need not leave leisure chaise longue and readjust chair back angle.

Owing to the leisure chaise longue structure is directly to form the lying posture form in response to user's rearward seat lying posture gesture conversion strength, so can sit the lying posture gesture and form the most suitable chair back angle according to user's difference, can cooperate human body fully, can not produce unsettled situation, no matter user's length service time all can be happy comfortable, the situation of not having a pain in the back.

The leisure chaise longue structure is included pedal in the bar linkage structure in, in using, can hold shank and sole, bear shank weight fully, and adjust the shank posture simultaneously according to sitting posture or lying posture conversion, make human body all be subjected to care, not have constriction, can loosen muscles and bones fully and reach happy comfortable leisure effect by head to pin.It is a kind of very intimate leisure chaise longue that meets very much the human body needs.

To express the function and benefit that the utility model can be reached in order understanding really, to cooperate diagram to enumerate specific embodiment, introduce its structure in detail.
