The specific embodiment
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, the present invention proposes a kind of self-regulating top waist device, and it comprises: through the fixing pedestal 11 of swivel chair underframe; Being fixed on the gripper shoe 10 on the pedestal 11 through first bearing pin 13 and second bearing pin 14, is the center of circle with first bearing pin 13 during gripper shoe 10 work, and be arranged in the strip hole of pedestal 11 second bearing pin 14 with connection be that the strong point rotates within the specific limits and moves back and forth; Be installed in the base plate 12 of pedestal 11 upper sides; Connect and be arranged on the top waist adjustment structure on the gripper shoe 10.
Wherein, waist adjustment structure in top comprises: be connected the adjustment (adjusting) lever 4 on the gripper shoe 10 through lever fixed axis 9; 2 two-way torque springs 2; Connect to be arranged on and be used for torsion spring adjustment structure that the elastic force of two-way torque spring 2 is regulated on the gripper shoe 10.
Specifically, the torsion spring adjustment structure comprises: through connector 1 and angle demodulator 3, and connector 1 all is arranged on the gripper shoe 10 through being connected fixed axis 8 connections with angle demodulator 3.
Connector 1 comprises: torsion spring angular adjustment bar 1a, axle sleeve 1b and brace 1c.Wherein, torsion spring angular adjustment bar 1a, axle sleeve 1b, brace 1c connect setting respectively, and 2 two-way torque springs 2 are socketed in two ends of axle sleeve 1b respectively.Angle demodulator 3 comprises: connecting rod 3a, support chip 3b and be connected slide block 3c; Wherein, Two support chip 3b connect two ends that are arranged on connecting rod 3a respectively, and the end of 2 two-way torque springs 2 is on the connecting rod 3a at the torsion spring angular adjustment bar 1a that puts at connector 1 front end with the certain pressure precompressed and angle demodulator 3 middle parts.
Connect fixed axis 8 through the corresponding fixing hole in gripper shoe 10 sides with through angle demodulator (3) lateral bolster fagging 3b corresponding aperture, and, connector 1 and angle demodulator 3 are fixed on gripper shoe 10 corresponding positions through connector 1 Upper shaft sleeve 1b endoporus.
Lever fixed axis 9 is fixed on adjustment (adjusting) lever 4 on the described gripper shoe 10 through the corresponding fixing hole in middle part, gripper shoe 10 sides.The lateral aperture on the slide block 3c of being connected on one end of adjustment (adjusting) lever 4 and the angle demodulator 3 cooperates and connects fixingly by regulating steady pin 7, and the other end cooperates with lever holder 5 on the pedestal 11, and by 6 fixed connections of lever steady pin.
The side front end fixing hole of base plate 12 cooperates with the front face corresponding aperture of pedestal 11, is fixed by the 4th bearing pin; Rear end, base plate 12 side fixing hole cooperates with middle part, gripper shoe 10 sides corresponding aperture, and is fixing by the 3rd bearing pin 15.
And connecting rod 17 1 ends are connected with connector 1, and the other end is connected with top back 18.Specifically, the torsion spring angular adjustment bar 1a of connector 1 is moved through connecting rod 17 drive top backs 18 by torsion spring angular adjustment bar 1a through connecting rod 17 connection top backs 18.
The centre bore of adjustment (adjusting) lever 4 is the center of circle with lever fixed axis 9, and an end of adjustment (adjusting) lever 4 is the center, is the strong point with lever steady pin 6 with pedestal 11 upper lever holders 5; The slide block 3c place that is connected on the other end of adjustment (adjusting) lever 4 and the angle demodulator 3 cooperates, and is fixedly connected by regulating steady pin 7.When gripper shoe 10 moves back and forth, because of the center fixation of adjustment (adjusting) lever 4 is different with the motor point, the center of circle of gripper shoe 10 with the strong point, so adjustment (adjusting) lever 4 is bigger than the movement angle of gripper shoe 10 when motion; One end of angle demodulator 3 is connected with adjustment (adjusting) lever 4; The other end is fastened on the gripper shoe 10 by connecting fixed axis 8; Adjustment (adjusting) lever 4 is in motion process; Angle demodulator 3 is the center of circle to connect fixed axis 8, and it is that the center rotates to connect fixed axis 8 down that an end of angle demodulator 3 drives at adjustment (adjusting) lever 4; And connector 1 deposits along with angle demodulator 3 associated movements 2 two-way torque springs 2 pressures.
Connector 1 is because of adopting L shaped design, other end swing at the volley.Connecting rod 17 1 ends are fixed on the brace 1c of connector 1, and the other end and top back 18 are connected through steady pin.Top back 18 can be that the center rotates a certain angle with top back steady pin.When gripper shoe 10 is center when rotation with first bearing pin 13, base plate 12 is the center of circle with the 4th bearing pin 16, is that the radius strong point is under the drive of gripper shoe 10 and rotate to an angle with the 3rd bearing pin 15.
In conjunction with shown in Figure 4; Top waist device is installed on the pallet 21 of swivel chair; Pedestal 11 is fixed on the general underframe 25 of swivel chair, and the chair back 22 is fixed on the gripper shoe 10, and seat support 24 is fixed on the base plate 12; Top back 18 independently is arranged on the chair back 22 and does not link to each other with the chair back 22, and top back 18 directly acts on user 23 waist.
When user 23 backs receded, the chair back 22 drove the rotation of tilting of gripper shoe (10) on the pallets 21, base plate 12 when gripper shoe 10 motions also along with motion.Be fixed on the gripper shoe 10 top waist device also each other motion make top back 18 to the motion of user 23 waist direction, and under the pressure of two-way torque spring 2 the realization waist support.
In addition; Top back 18 can be according to user's 23 waist angles and adjusting angle automatically; And top back 18 requires down at user 23 waist, can regulate automatically that required angle reaches the best sitting posture of user 23 and in the comfort level of the process of layback through top waist device.
As shown in Figure 5; In another embodiment; Top back 18 is arranged in the chair back 22; Be among Fig. 5 not top back 18 have only a chair back 22, and the chair back 22 directly acts on user 23 waist, and the chair back 22 is through the fixing lower end and be fixed on the brace 1c of connector 1 through corresponding jockey and pivot pin of back rest supports frame 26.The pallet 21 that will have top waist device is fixed on the general underframe of swivel chair 25 through the fixing hole on the pedestal 11; On the base plate 12 of seat support 24 fixed trays 21; One end of back rest supports frame 26 is connected with the middle part of the chair back 22 and fixes with pivot pin, and the connecting portion of the gripper shoe 10 on the other end and the pallet 21 is connected fixing; After the 26 terminal corresponding connections of junction, the chair back 22 middle part and back rest supports frame were fixed, the lower end also was fixed on the brace 1c of connector 1 through corresponding jockey and pivot pin;
The chair back 22, back rest supports frame 26 are that the center rotatablely moves in certain angle towards certain orientation with first bearing pin 13 on the pallet 21.It is the center of circle that the chair back 22 middle parts rely on the fixing point on the back of the body bracing frame 26; The lower end be drive in top waist device when motion of the strong point on pallet 21 chair back 22 to the motion of user's 23 waist directions when the chair back 22 recedes, seat support 24 rotatablely moves under 10 drives of the gripper shoe on the pallet 21 within the specific limits.
Therefore; Top waist device is element task with pallet 21, and the motion mode of the integral type chair back 22 waist support swivel chairs (two kinds of different motion states in Fig. 5, representing the chair back 22 and back rest supports frame 26 respectively with solid line and dotted line) can both let user 23 needed angle of waist and pliability reach optimum state.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
