The lifting motor stretches and retracts to push the cushion frame to rotate, so that the cushion is lifted and inclined, and the effect of easily standing on the ground from the chair is achieved. The iron frame of the old chair can rotate 360 degrees in the sitting posture state and the lying posture state, so that the leisure and comfort effect is achieved. The headrest is connected with the lifting rod through a hinge, and the rotation of the headrest can be adjusted. The lifting rod and the backrest can be adjusted up and down, so that a better comfortable effect of the head is achieved.

The leisure chair for the elderly of the embodiment needs to be described in the following, wherein the footrest assembly can be folded and retracted to the lower part of the seat, and the included angle between the footrest surface and the ground can reach a flat state of 30-32 degrees, as shown in fig. 1. The chair has the advantages that when a person sits, the legs have larger rest space, the feeling of propping against the legs cannot occur, the whole chair looks more integrated, and the functional characteristics of breakthrough in usability and attractiveness are realized. The specific working principle is as follows: the control panel controls the cushion motor to contract, so that the cushion oscillating bar swings, and the cushion moves forwards. Because the cushion moves forward, the rotation axis, the pedal connecting rod and the pedal power iron sheet through the pedal can drive the pedal assembly to rotate inwards, when the pedal support rotates inwards, the second connecting rod is made to extend, so that the third connecting rod is driven to rotate inwards, the third connecting rod drives the fourth connecting rod to also rotate inwards, and the pedal plate contracts due to the fourth connecting rod and the guide rail, so that the pedal support can contract relatively. When the motor retracts to the minimum stroke, the pedal also retracts to the minimum distance at the same time, the pedal device swings to retract below the seat, and the included angle between the pedal surface and the ground can reach a level state of 25 degrees.

In addition, as shown in fig. 10, the extension function design of the foot pedal of the leisure chair for the old people of the embodiment enables the overall length of the foot pedal to reach more than 500mm, so that the leisure chair for the old people can meet the requirements of people with different heights. The specific working principle is as follows: the pedal component is connected with the cushion through a pedal rotating shaft and a pedal connecting rod, and the pedal power iron sheet is connected with the bracket connecting rod. The cushion swing rod is connected with the cushion through a pin, and the cushion swing rod is connected with the support through a pin. The pedal power iron sheet is connected with the pedal bracket through a pin to rotate. The rotating shaft of the pedal bracket is connected with the cushion through a pin to rotate. The user controls the cushion motor to extend through the control panel, so that the cushion swing rod swings, and the cushion moves backwards. The cushion moves backwards, the pedals can be driven to rotate outwards through the rotating shafts of the pedals, the pedal connecting rods and the pedal power iron sheets, the second connecting rods contract to drive the third connecting rods to rotate outwards when the pedal support rotates outwards, the third connecting rods drive the fourth connecting rods to rotate outwards, and the pedals extend relative to the pedal support under the action of the fourth connecting rods and the guide rails. When the motor extends to the maximum stroke, the pedal also extends to the maximum distance at the same time, and the function of lengthening and extending the pedal is realized.

Example two

As shown in fig. 1 to 11, the present embodiment is similar to the embodiment except that a brake mechanism 521 for preventing the seat cushion 21 from rotating is provided at the rotating shaft 52. The rotating shaft 52 is provided with a brake mechanism 521 for preventing the seat cushion from rotating, so that when the seat cushion is lifted, the brake mechanism 521 can fix the bracket to prevent the seat from rotating, thereby better ensuring the safety of a user. The brake mechanism comprises an iron piece, a screw rod, a spring, a gear and the like.

The iron frame of the leisure chair for the old can rotate 360 degrees in a sitting posture state and a lying state, and the leisure and comfort effects are achieved. Because this product pivot 52 department has arrestment mechanism 521, when the cushion goes up and down, arrestment mechanism can be fixed with the support, prevents that the seat from rotating to guarantee user's safety better.

The specific working principle is as follows: a bearing 523 is installed between the rotation shaft 52 and the rotation shaft housing 522. The bearing 523 is fixed in the rotating shaft housing 522 by screws. The fixed gear 524 is fixedly installed outside the rotation shaft housing 522 to be prevented from rotating. The guide post 525 penetrates through a part of the through hole of the bracket 53, and is connected with the spring pressing plate 526 and the braking gear plate 527 into a whole through a screw, as shown in the following figures. The spring 528 is installed in a counter bore above the rotating shaft and is compressed by a spring pressure plate, and in a normal state (when the geriatric chair is not lifted), the brake gear is lifted upwards by the whole pressure plate assembly due to the action of the spring force to be meshed with the fixed gear, so that the rotating shaft cannot rotate.

When the seat is in a lying state and a standing state, the cushion frame iron sheet presses the spring pressing plate, the brake gear is separated from the fixed gear and is not meshed with the fixed gear, and the rotating shaft can rotate freely. When the seat is in a lifting state, the cushion frame iron sheet cannot press the spring pressing plate, the brake gear and the fixed gear are separated from each other and meshed together under the action of spring force, and the rotating shaft cannot rotate.
