Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to specific embodiments and the accompanying drawings.

As shown in fig. 1, a leisure chaise longue comprises a chaise longue main body 1, a folding backrest 2 arranged on the chaise longue main body 1, a pulley 4 arranged at the lower part of the chaise longue main body 1 and a supporting foot 5 arranged at the lower part of the chaise longue main body 1.

As shown in fig. 1 and 3, the recliner chair main body 1 comprises two mutually parallel arc-shaped edges 13, arc-shaped reinforcing rods 12 arranged in the middle of the two arc-shaped edges 13, two arc-shaped short rods 14 respectively arranged at two ends of the two arc-shaped edges 13, and a first cushion 9 arranged on the arc-shaped edges 13. The first cushion 9 is formed by a wrapping cord wrapped around two arcuate edges 13. The first backrest 9 of the recliner chair body 1 is arranged on the arcuate edge 13 between the arcuate reinforcement bar 12 and an arcuate stub bar 14. The end of the arched edge 13, which is not provided with the first cushion 9, close to the arched short rod 14 is provided with a groove 16 which is matched with the folding backrest 2. The bending direction of the arc-shaped reinforcing rod 12 is the same as that of the arc-shaped short rod 14, and the bending direction of the arc-shaped edge 13 is opposite to that of the arc-shaped short rod 14.

As shown in fig. 1 and 2, the folding backrest 2 includes two mutually parallel short arcuate sides 10, arcuate rods 11 disposed at both ends of the two short arcuate sides 10, a support frame 3 disposed on the short arcuate sides 10, and a second cushion 17 disposed on the short arcuate sides 10. One ends of the two arcuate short sides 10 are connected to the middle of the two arcuate sides 13 by hinges, respectively. The hinge is provided with a torque sensor, the deck chair main body 1 is also provided with a control module 6, and the control module 6 is respectively electrically connected with the torque sensor and the support frame 3 through leads. The support frame 3 comprises two mutually parallel telescopic rods, and the telescopic rods are electrically connected with the control module 6 through wires.

In order to assist the lying person and control the rotation speed of the folding backrest 2, so as to prevent the folding backrest 2 from rotating too fast and causing injury to the user, two torque values with different magnitudes are set in the control module 6, when the control module 6 receives a torque value detected by the torque sensor which is larger than the set large torque value, the control module 6 controls the two telescopic rods to contract synchronously until the control module 6 receives a torque value detected by the torque sensor which is smaller than the set large torque value and larger than the set small torque value or the telescopic rods are in the shortest extension state, the telescopic rods stop contracting. When the control module 6 receives a torque value detected by the torque sensor and is smaller than a set small torque value, the control module 6 controls the two telescopic rods to extend synchronously until the control module 6 receives a torque value detected by the torque sensor and is smaller than the set large torque value and larger than the set small torque value or the telescopic rods are in the longest extension state, and the telescopic rods stop extending. When the control module 6 receives that the torque force value detected by the torque sensor is smaller than the set large torque force value and larger than the set small torque force value, the length of the telescopic rod is kept unchanged. The both ends of telescopic link are equipped with the spring through the one end and the connecting block of second hinged joint bow-shaped limit 13 respectively on the connecting block, and the connecting block and folding back 2 are connected respectively to the both ends of spring.

The telescopic rod is a hydraulic telescopic rod, the extension or contraction speed of the telescopic rod is constant, and the extension or contraction speed of the telescopic rod is kept at 0.5 m/s.

The bow of the short arcuate side 10 is in the opposite direction to the bow of the curved bar 11.

In order to increase the ground contact area and reduce the risk of sinking, the area of the support foot 5 in contact with the ground is much larger than the area of the cross section of the support foot 5 in contact with the recliner body 1. Preferably, the support foot 5 is an inverted T-shape.

The embodiments of the invention are intended to embrace all such alternatives, modifications and variances that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, substitutions, improvements and the like that may be made without departing from the spirit and principles of the invention are intended to be included within the scope of the invention.
