Abstract

A leisure lounger includes a rack, a upper mattress and a lower mattress. The lower and upper mattresses straddle the top of the rack in a horizontal manner. The rack has a horizontal pivotal bar running through two lugs on the left side and right side of the bottom of the upper mattress. A lifting unit is provided that has an extensible strut on the top. The extensible strut has a top portion hinged on a yoke located on the bottom of the upper mattress close to the juncture of the upper and lower mattresses. The extensible strut can be retracted to move the upper mattress in a reclined manner, and the lower mattress adjacent to the upper mattress sinks in an inclined manner at a selected angle. Therefore a user can sit on the lower mattress in a reclined manner with the hip retained without slipping forwards.

Description

FIELD OF THE INVENTION
• The present invention relates to a liftable lounger and particularly to a lounger that has an upper mattress liftable in a reclined manner to form a slightly downward inclined juncture between the upper mattress and a lower mattress to prevent people's body from slipping forwards.
BACKGROUND OF THE INVENTION
• The conventional movable loungers enable people's body to lie thereon in a reclined manner so that the upper portion of the body can rest on a upper mattress while the lower portion of the body can sit on a lower mattress. Due to lying on the mattress in a flat manner is not convenient for people to do eating, drinking, reading or sunbathing, the movable lounger provides functions different from the ordinary bed. In addition to allow people's body to lie thereon flatly for resting and sleeping, the lounger also is liftable to enable people's body to lie thereon in a reclined manner. Hence the mattress is divided into a upper mattress and a lower mattress. The upper and lower mattresses can be laid on the same horizontal position to hold people's body in a flat manner. The upper mattress is liftable upwards to form a selected angle against the lower mattress so that people's hip can rest on the lower mattress with the legs extending outwards, while the upper portion of the people can rest on the upper mattress in a reclined manner. While the people sits on the lounger in the reclined manner the body weight falls on the lower portion of body, the hip tends to slip forwards along the lower mattress. When the upper mattress is lifted higher people's body tends to slip forwards even further away. As a result, people sitting on the lounger cannot maintain at the still posture very long, and has to move backwards constantly to move the hip to the original position to recline at the most suitable angle.
SUMMARY OF THE INVENTION
• In view of the problem mentioned above, the primary object of the present invention is to provide a leisure lounger that includes a rack, a lower mattress and a upper mattress. The lower mattress and the upper mattress straddle horizontally the top of the rack. The rack has a transverse pivotal bar running through two lugs on the left side and right side of the bottom of the rack, and a lifting unit which has an extensible strut on the top. The extensible strut has a top portion hinged on a yoke which is located on the bottom of the upper mattress close to a juncture of the upper and lower mattresses. When the extensible strut is retracted, the upper mattress is reclined upwards, and the lower mattress close to the juncture with the upper mattress reclines downwards to form an inclined angle directing downwards so that a user who sits on the lower mattress in a reclined manner can have his/her back resting on the upper mattress in the reclined manner with the hip retained to prevent the body from slipping forwards.
• The foregoing, as well as additional objects, features and advantages of the invention will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
• FIG. 1 is a perspective view of an embodiment of the invention.
• FIG. 2 is a fragmentary perspective view of an embodiment of the invention.
• FIG. 3 is another fragmentary perspective view of an embodiment of the invention.
• FIG. 4A is a side view of an embodiment of the invention.
• FIG. 4B is a schematic view of the invention according toFIG. 4A in an operating condition.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
• Please refer toFIGS. 1,2 and3, the leisure lounger according to the invention includes:
• arack10 which is designed according to the height of people at a length sufficient to hold people's body in a lying manner and may be rested on a ground floor. It has a transversepivotal bar11 on an upper side;
• alower mattress20 which is elastic and pliable, and located on a lower half portion of therack10, and straddles the top side of therack10;
• anupper mattress30 which also is elastic and pliable, and located on a upper half portion of therack10, and straddles the top side of therack10. It is formed at a length smaller than that of thelower mattress20;
• a pair oflugs31 which are located on a left side and a right side of the bottom of theupper mattress30, and have respectively anaperture32 run through by thepivotal bar11;
• ayoke33 located beneath theupper mattress30 close to thelower mattress20 as shown inFIG. 3; and
• alifting unit40 which is a pressurized cylinder and has anextensible strut41 on the top driven by a driving source42 (such as a motor) to extend and retract up and down. It has the top end hinged on theyoke33.
• By means of the construction set forth above, when a user wants to lie flatly on the leisure lounger, referring toFIG. 4A, theextensible strut41 is extended upwards to push theupper mattress30 upwards. Theaperture32 rotates about thepivotal bar11 until theupper mattress30 straddles the top side of therack10 in a horizontal manner. Thelower mattress20 also is moved through the upward pushing of theextensible strut41 at the same horizontal position with theupper mattress30. Hence the user can lie thereon flatly.
• Referring toFIG. 4B, when the user wants to sit on the lounger in a reclined manner, the upper portion of the body rests on theupper mattress30 in the reclined manner while the lower portion of the body sits on thelower mattress20, theextensible strut41 is retracted downwards. The tail end of theupper mattress30 is drawn downwards, and the top end of theupper mattress30 can be moved upwards by hands to enable theaperture32 to rotate about thepivotal bar11 so that theupper mattress30 is gradually lifted upwards in the reclined manner. It is to be noted that when theextensible strut41 is retracted downwards, thelower mattress20 also is drawn so that the portion of thelower mattress20 adjacent to theupper mattress30 is inclined downwards such that the top surface of thelower mattress20 sinks slightly lower. Therefore when user's hip sits thereon with the legs extending forwards, the hip is located on a lower elevation than the legs. With user's back resting on theupper mattress30, user's hip does not slip forwards.
• Prototypes of the invention have been made and tested with desired results. The object and expecting functions are fully accomplished. It offers a significant improvement over the conventional loungers.
• While the preferred embodiment of the invention has been set forth for the purpose of disclosure, modifications of the disclosed embodiment of the invention as well as other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
