Abstract

The utility model relates to a reclining chair having independently-adjustable supporting parts operated by motor. The utility model is composed of a back rest 1, a seat stool 2 and a foot pad 3. By using a transmission belt 5, a motor 4 can drive an inverse and positive threaded rod 6, and a bevel gear 9 is arranged at the middle of the inverse and positive threaded rod 6; thus, a back rest lifting device 7 can be driven to change the relative position of the back rest 1 and the seat stool 2. The bevel gear 9 can drive a drive rod 11 of the foot pad, so a moveable connecting rod 17 and a passive connecting rod 18 can be driven; thus, the foot pad 3 can move along the front edge of the seat stool 2 up and down. When the utility model is used, the motor is used as the motive power and is utilized to manipulate the back rest, the seat stool and the foot pad to change the relative position; thus, the reclining chair of horizontal bed type can be formed, or the reclining chair of back rest and foot pad type can be formed.

Description

Reclining chair having independently-adjustable supporting parts operated by motor
The utility model belongs to field of furniture, refers to that specifically lying of electronic conversion backrest of energy and foot pad position is partial.
Existing chaise longue is in many styles, there is the backrest of the wooden work of traditional bamboo fixedly to have the chaise longue of foot pad, what also the useful metal frame was made can change backrest angle and have the fixedly chaise longue of foot pad, but the shift in position of this chaise longue has certain restriction, and must apply certain mechanical force when the conversion position of back just can achieve the goal, particularly foot pad partly is difficult to can't make the people reach the requirement of the most comfortable people's bodily form of whole body for learning when changing position of back in coordinating with backrest.
The purpose of this utility model is to propose a kind of intelligentized design at the defective that has chaise longue now, utilize motor as power, can change backrest and foot pad position arbitrarily, or make backrest, seat and foot pad be in same horizontal plane and form bed, or backrest is steeved, foot pad partly sinks to forming a kind of chaise longue with backrest and foot pad automatically, made things convenient for the person of using like this, particularly be adapted to the elderly to comfortable requirement, also eliminated existing chaise longue and when changing backrest, foot pad position, must stand and apply the defective of external force.
Design of the present utility model is chaise longue is divided into backrest, bench and foot pad three partly, and for the seat stool, backrest and foot pad can both be done relative motion, to change the different demand of shape adaptation seat person of chaise longue.The design utilizes a reducing motor to be power, drives an anti-suitable threaded rod, and this Nut pole drives the lowering or hoisting gear of being made up of connecting rod can make backrest change angle; And a bevel gear is housed to drive the foot pad drive link in anti-centre along threaded rod, the foot pad lowering or hoisting gear that drive is made up of connecting rod, the position of foot pad is changed, to reach the lie position or the seat of the best (promptly the most comfortable) that the human body behaviouristics requires along with the variation of position of back.
The utility model is reasonable in design, make simple, utilize the power of reducing motor, can make the respectively partly variation of position, slow, comfortable, be applicable to the leisure use of household or senior public place, particularly solve the elderly's slow movement, but wanted upper and lower chaise longue when wanting to change sitting posture, firmly changed the difficulty of chaise longue form.
Details are as follows in conjunction with the accompanying drawings for the utility model:
Fig. 1 is the design's schematic perspective view;
Fig. 2 is the design's transmission mechanism schematic diagram;
Fig. 3 foot pad driving mechanism schematic diagram.

Reclining chair having independently-adjustable supporting parts operated by motor body portion three partly as shown in Figure 1: i.e. backrest 1, seat stool 2 and foot pad 3; Above-mentioned seat stool 2 and foot pad 3 are installed on the underframe 15 that has castor 16, and backrest 1 is connected with the 2 usefulness rotating shafts 21 of seat stool, make backrest 2 21 changes around the shaft and an angle on stool plane.3 of above-mentioned foots pad can change its level height along the edge lifting of seat stool 2.As depicted in figs. 1 and 2, a motor 4 with deceleration is housed on underframe 15, this motor 4 can drive anti-along threaded rod 6 through driving belt 5, and anti-rotation along threaded rod 6 can be controlled hoisting gear for backrest 7 and can 21 rotate around the shaft to impel backrest 1.This hoisting gear for backrest 7 is made up of moving connecting rod 72 of 74,2 drive connecting rod 71,2 velamens of 2 nuts and top 73.Above-mentioned nut 74 places anti-both sides along threaded rod 6 respectively, and it is hinged with hinge 8 (for simplifying narration with an end of drive connecting rod 71, the Reference numeral of the moveable hinge in this specification is 8), the middle part of above-mentioned 2 drive connecting rod 71 is hinged with hinge 8, one end of the other end of drive connecting rod 71 and passive connecting rod 72 is hinged, the other end of passive connecting rod 72 is hinged and top 73 is housed, this top 73 is loaded on the back of backrest 1, therefore 2 nuts 74 are done relative motion when anti-rift grain threaded rod 6 rotates, order about drive connecting rod 71 and passive connecting rod 72 and top 73 simultaneously and do elevating movement, and then backrest 1 is rotated around axle 21, change the relative position of backrest 1 and seat stool 2, its angle can be between 90 °-180 °, so the design both can be arm-chair, and the bed that can be used as level again uses.
By Fig. 1,2,3,4 as seen, in anti-centre a bevel gear 9 is housed along threaded rod 6, the bevel gear 101 of bevel gear power transmission shaft 10 ends and bevel gear 9 engagements, the other end of bevel gear power transmission shaft 10 has screw thread, foot pad drive rod 11 is through the nut 111 and its engagement at middle part, the two ends of this foot pad drive rod 11 are provided with the roller 112 that can move along underframe 15 front slideways 151, these roller 112 each hinged 1 drive connecting rod 17, the other end of drive connecting rod 17 is connected in the foot pad front end with fixing hinge 121, connecting rod 18 is moved with fixing hinge 121 each hinged velamen in the two ends of this external underframe front end, the other end of this passive connecting rod 18 has a roller 19, and the middle part of drive connecting rod 17 and passive connecting rod 18 is connected with hinge 8.Therefore, drive foot pad drive rod 11 advances or retreats when bevel gear drive link 10 rotates, make roller 112 advance or retreat and further make drive connecting rod 17 and passive connecting rod 18 to move along underframe guide rail 151, because an end of drive connecting rod 17 and an end of passive company 18 are connected in foot pad 3 front ends with fixing hinge 121 respectively, therefore when foot pad drive rod 11 travels forward, roller 112 and roller 19 also travel forward, foot pad 3 rises this moment; Otherwise then foot pad descends, and reaches the purpose that foot pad 3 matches with the position of backrest 1 automatically.
Therefore, after starting motor (4), drive anti-along threaded rod 6 through driving belt (5), and then driving hoisting gear for backrest 7, make 21 rotations around the shaft of top 73 control backrests 1, change the relative position of seat stool 2 and backrest 1, bevel gear 9 orders about 10 rotations of bevel gear power transmission shaft simultaneously, and then drive foot pad drive rod 11 and move forward and backward, and drive drive connecting rod 17 and 18 motions of passive connecting rod, foot pad 3 is moved up and down along seat stool 112 leading edges.
