  monitor keywords FIELD OF THE INVENTION

The present invention relates to chaises, and particularly to a chair capable of being adjusted as a chaise which has both the function of seating and lying so as to provide the inconvenience to users.

BACKGROUND OF THE INVENTION

U.S. Pat. No. 5,950,259 discloses a lounge chair that includes an upper body support portion, an aperture extending through said upper body support portion, and a movable flap secured to the upper body support portion for selectively covering and uncovering the aperture. In particular, the flap can be repositioned to cover and uncover an aperture through a upper body support portion without having to get up out of the chair and without having to reposition the upper body support portion.

U.S. Pat. No. 4,470,630 discloses a portable folding chair which is adaptable for use in an upright conventional sitting mode, in an inverted position as a back rest and in a collapsed position as a carrying device. The rear leg member and chair back are adjustable so that the rear leg member defines a comfortable headrest in the inverted backrest mode and a flap is provided which defines a lounging mat in the back rest mode which, in use, anchors the chair in place and in the collapsed carrying mode defines with the seat and back panels a covered carriage compartment.

While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical pivoted leg assembly that can support the main lounge support panels at a variety of different angular orientations relative to one another, as well as the horizontal plane. While all of the prior art devices include at least one horizontally disposed support panel that coincides with the user\'s mid torso, there are many instances wherein it would be desirable to dispose the seat portion of the lounge chair at an angle other than the horizontal plane. As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved type of adjustable angle chaise lounge construction that employs a unique leg support arrangement that permits the three main lounge panels to be disposed at a variety of angles relative to one another, and the provision of such a construction is a stated objective of the present invention.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide a chair capable of being adjusted as a chaise which has both the function of seating and lying so as to provide the inconvenience to users.

To achieve above objects, the present invention provides a chair capable of being adjusted as a chaise which comprises a cushion assembly including a first cushion, a second cushion and a third cushion; a first rotary shaft being used to pivotally connect the first cushion and the second cushion; a second rotary shaft being used to pivotally connect the second cushion and the third cushion; an adjusting unit installed below the first cushion; a chair support structure being installed between the first cushion, a second cushion and a third cushion; the chair support structure including an assisting support frame and a support frame; the assisting support frame installed between the first cushion and the third cushion; the support frame being installed below the third cushion. The first cushion is used as a pad for seating; the second cushion is used as a chair back rested by the back of the user; the third cushion is folded with respect to the second cushion to be located at a backside of the second cushion.

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
