The specific embodiment
In conjunction with Fig. 1, Fig. 2 and shown in Figure 3, the present invention proposes a kind of top waist device of automatic adjusting, and it comprises: by the fixing pedestal 11 of swivel chair underframe; Be fixed on gripper shoe 10 on the pedestal 11 by the first bearing pin 13 and the second bearing pin 14, take the first bearing pin 13 as the center of circle, and be arranged on take connection that the second bearing pin 14 moves back and forth as the strong point rotates within the specific limits in the strip hole of pedestal 11 during gripper shoe 10 work; Be installed in the base plate 12 of pedestal 11 upper sides; Connect the top waist adjustment structure that is arranged on the gripper shoe 10.
Wherein, waist adjustment structure in top comprises: be connected to adjustment (adjusting) lever 4 on the gripper shoe 10 by lever fixed axis 9; 2 two-way torque springs 2; Connect and be arranged on the gripper shoe 10 for the torsion spring adjustment structure that the elastic force of two-way torque spring 2 is regulated.
Specifically, the torsion spring adjustment structure comprises: by connector 1 and angle demodulator 3, and connector 1 is connected with angle demodulator all and is connected and be arranged on the gripper shoe 10 by being connected and fixed axle 8.
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 respectively two ends of axle sleeve 1b.Angle demodulator 3 comprises: connecting rod 3a, support chip 3b and connection sliding block 3c, wherein, two support chip 3b connect respectively two ends that are arranged on connecting rod 3a, 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.
Be connected and fixed axle 8 and pass through the corresponding fixing hole in gripper shoe 10 sides and pass through angle demodulator (3) lateral bolster fagging 3b corresponding aperture, and by connector 1 Upper shaft sleeve 1b endoporus, connector 1 and angle demodulator 3 are fixed on gripper shoe 10 corresponding positions.
Lever fixed axis 9 is fixed on adjustment (adjusting) lever 4 on the described gripper shoe 10 by the corresponding fixing hole in middle part, gripper shoe 10 sides.Lateral aperture on the connection sliding block 3c on one end of adjustment (adjusting) lever 4 and the angle demodulator 3 cooperates by regulating steady pin 7 and is connected and fixed, and the other end cooperates with lever holder 5 on the pedestal 11, and is fixedly connected with by lever steady pin 6.
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 connects top back 18 by connecting rod 17, drives back 18 motions in top by torsion spring angular adjustment bar 1a by connecting rod 17.
The centre bore of adjustment (adjusting) lever 4 is take lever fixed axis 9 as the center of circle, and an end of adjustment (adjusting) lever 4 is centered by pedestal 11 upper lever holders 5, take lever steady pin 6 as the strong point; The other end of adjustment (adjusting) lever 4 cooperates with connection sliding block 3c place on the angle demodulator 3, and is fixedly connected with by regulating steady pin 7.When gripper shoe 10 moves back and forth, because of the center of adjustment (adjusting) lever 4 fixing different from the motor point, the center of circle of gripper shoe 10 with the strong point, so adjustment (adjusting) lever 4 is larger than the movement angle of gripper shoe 10 when moving; One end of angle demodulator 3 is connected with adjustment (adjusting) lever 4, the other end is fastened on the gripper shoe 10 by being connected and fixed axle 8, adjustment (adjusting) lever 4 is in motion process, angle demodulator 3 is to be connected and fixed axle 8 as the center of circle, and an end of angle demodulator 3 rotates centered by being connected and fixed axle 8 under adjustment (adjusting) lever 4 drives; And connector 1 deposits along with angle demodulator 3 associated movements 2 two-way torque springs 2 pressures.
Connector 1 is because adopting L shaped design, at the volley other end swing.Connecting rod 17 1 ends are fixed on the brace 1c of connector 1, and the other end and top back 18 are connected by steady pin.Top back 18 can rotate a certain angle centered by the back steady pin of top.When gripper shoe 10 was rotated centered by the first bearing pin 13, base plate 12 was take the 4th bearing pin 16 as the center of circle, take the 3rd bearing pin 15 as the radius strong point under the drive of gripper shoe 10 and rotate to an angle.
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, the chair back 22 is fixed on the gripper shoe 10, 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 gripper shoe (10) Sloped rotating on the pallets 21, base plate 12 when gripper shoe 10 motion also along with motion.Be fixed on the gripper shoe 10 top waist device also mutually motion make top back 18 to the motion of user 23 waist direction, and under the pressure of two-way torque spring 2, realize waist support.
In addition, top back 18 can be according to user's 23 waist angles and automatic adjusting angle, and top back 18 is under user 23 waist requires, and can automatically regulate sitting posture that required angle reaches user's 23 the bests and in the comfort level of layback process by 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 only have a chair back 22, and the chair back 22 direct effect users' 23 waist, and the chair back 22 is by the fixing lower end and being fixed on by corresponding jockey and pivot pin on the brace 1c of connector 1 of backrest support frame 26.To be fixed on the general underframe of swivel chair 25 by the fixing hole on the pedestal 11 with the pallet 21 of top waist device; On the base plate 12 of seat support 24 fixed trays 21; One end of backrest support 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 and fixed; After junction, the chair back 22 middle part and backrest support frame 26 terminal corresponding being connected and fixed, the lower end also is fixed on by corresponding jockey and pivot pin on the brace 1c of connector 1;
The chair back 22, backrest support frame 26 rotatablely move in certain angle towards certain orientation centered by the 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 support 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 gripper shoe 10 drives on the pallet 21 within the specific limits.
Therefore, top waist device is take pallet 21 as element task, and the motion mode of the integral type chair back 22 waist support swivel chairs (two kinds of different motion states that represent respectively the chair back 22 and backrest support frame 26 in Fig. 5 with solid line and dotted line) can both allow user 23 the needed angle of waist and pliability reach optimum state.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
