Detailed Description

The present application is described in further detail below with reference to figures 1-8.

The embodiment of the application discloses a multi-gear control device for bedding. Referring to fig. 1 and 2, a multi-gear control device for bedding includes a four-bar linkage 1, a latch mechanism 2, and a control mechanism 3. The four-bar mechanism 1 and the locking mechanism 2 are both provided with two, and one four-bar mechanism 1 corresponds to one locking mechanism 2. The two four-bar linkages 1 are respectively used for being arranged at two sides of the bed backrest 9. Referring to fig. 3, the four-bar linkage 1 includes a first bar 4, a third bar 6, a second bar 5, and a fourth bar 7 which are rotatably connected to each other in turn. The first rod 4 is fixedly mounted on the bed frame 8 and the second rod 5 is fixedly mounted on the bed back 9. The control mechanism 3 controls the locking mechanism 2 to lock the four-bar linkage 1 or unlock the four-bar linkage 1.

The four-bar linkage 1 is in an initial state, see fig. 3 and 4. When the angle of the bed back 9 needs to be adjusted, the control mechanism 3 controls the locking mechanism 2 to unlock the four-bar mechanism 1, so that the four-bar mechanism 1 can move, at the moment, the bed back 9 can be driven to rotate relative to the bed frame 8 by applying force to the bed back 9, until the bed back 9 rotates to a proper angle, the control mechanism 3 does not apply force to the locking mechanism 2 any more, so that the locking mechanism 2 restores the state of locking the four-bar mechanism, and the angle of the bed back 9 is stabilized at an artificially adjusted angle. The angle of the bed backrest 9 can be adjusted, thereby meeting different use requirements. The maximum angle of movement of the four-bar linkage 1 is shown in fig. 5 and 6.

Specifically, referring to fig. 7 and 8, the locking mechanism 2 includes a shift position control lever 10, a latch 11, a fixed seat 12, a rotating member 13, a push plate 14, and an elastic member. The gear control rod 10 is arranged in an arc shape, and a plurality of jacks 16 are arranged on the gear control rod 10 at equal intervals. Six mounting holes 17 are formed in the first rod 4 at intervals along the length direction of the first rod, two mounting nails 18 are arranged on the gear control rod 10, and one mounting nail 18 is used for being fixedly connected with any one mounting hole 17. The gear control lever 10 is fixedly mounted in position relative to the first lever 4 by means of a mounting peg 18.

Referring to fig. 7 and 8, the holder 12 is fixedly mounted on the third rod 6. The rotating part 13 comprises a rotating seat 19 and a mounting seat 20, the rotating seat 19 is rotatably connected to the fixed seat 12, the mounting seat 20 is fixedly mounted on the rotating seat 19 through a bolt, and the mounting seat 20 is used for connecting the control mechanism 3. The push plate 14 is fixedly mounted on the rotary member 13. The latch 11 passes through the push plate 14 and is slidably coupled to the push plate 14. The bolt 11 is provided with a clamp spring 21, and the clamp spring 21 is abutted to one side of the push plate 14, which is far away from the gear adjusting rod. The elastic element is a pressure spring 15, the bolt 11 is sleeved with the pressure spring 15, and two ends of the pressure spring 15 are abutted against the third rod 6 and the clamp spring 21.

The control mechanism 3 drives the rotating part 13 to rotate, so that the push plate 14 pushes the latch 11 to leave the insertion hole 16, and the four-bar mechanism 1 is unlocked, and the bed backrest 9 can move relative to the bed frame 8. When the control mechanism 3 does not apply a force to the rotating member 13, the elastic member drives the plug 11 to be inserted into the insertion hole 16, and at this time, the plug 11 also pushes the push plate 14 to rotate the rotating member 13 to an initial state relative to the fixed base 12. The bed back 9 is fixed relative to the bed frame 8. Optionally, a reset element for keeping the rotating element 13 in the initial state is disposed between the rotating element 13 and the fixing base 12, and the reset element may be a torsion spring. In the initial state, the control mechanism 3 does not apply a force to the rotor 13.

Referring to fig. 7, when the four-bar linkage 1 is locked by the lock mechanism so that the control mechanism 3 does not apply a force to the rotary member 13, the latch 11 is stably inserted into the insertion hole 16. The second and fourth bars 5, 7 are rotatably connected by a torsion spring return assembly 22. The torsion spring return assembly 22 includes a torsion spring and an end cap. The torsion spring is used to drive the second and fourth bars 5, 7 back to their natural state. The end cap is used to cover the torsion spring, the rotational connection point of the second rod 5 and the fourth rod 7. Thereby reducing the probability of interference of the torsion spring by sundries.

If the control mechanism 3 no longer applies a force to the rotary part 13, the four-bar linkage 1 cannot be locked if the pin is not aligned with the insertion hole 16 at this time. At this time, the torsion spring reset assembly 22 drives the second rod 5 and the fourth rod 7 to rotate, so that the shape of the whole four-bar mechanism 1 changes, and the pin enters the nearest jack 16 to achieve a locking state. Ensures that the bed back 9 remains stable with respect to the bed frame 8 after the angle adjustment.

Referring to fig. 2 and 7, the control mechanism 3 includes a connecting link 23, two pulling wires 24, and a force applying member 25. One pull wire 24 corresponds to one locking mechanism. The connecting base 23 is fixedly arranged in the middle of the bedstead 8. One end of the pull wire 24 is fixedly connected to the mounting seat 20 through a bolt, and the other end passes through the connecting seat 23. The two pulling wires 24 are fixedly connected to the force applying member 25. The force applying member 25 may be a tab, a lug, a flexible lug, etc. In this embodiment, the force applying member 25 is a tab made of cloth tape.

By applying force to the force application part 25 and transferring force through the pull wire 24, the rotating part 13 is pulled to rotate relative to the fixed seat 12, and the unlocking of the four-bar mechanism 1 is completed. When the force applying element 25 is no longer applied, the rotating element 13 and the bolt 11 are both reset, and the four-bar mechanism 1 is locked.

Referring to fig. 5, in order to prevent the bed back 9 from rotating excessively, the shift lever 10 is provided with a stopper 26. The limiting member 26 can be a limiting block, a limiting rivet, etc., and in this embodiment, the limiting member 26 is a limiting rivet. When the second rod 5 is parallel to the third rod 6, the limiting member 26 abuts against the third rod 6. At this time, the four-bar linkage 1 cannot move further toward the limiting member 26, so that the bed back 9 does not rotate excessively. Meanwhile, referring to fig. 3, when the four-bar mechanism 1 is in the initial state, the limiting member 26 abuts against the inward side of the fourth bar 7, and the first bar 4 cannot move toward the fourth bar 7 any more, so that the bed back 9 does not excessively rotate.

3. after the bed back 9 is adjusted to a proper angle, the force application piece 25 is loosened, at this time, the pull wire 24 does not apply force to the rotating piece 13 any more, and the bolt 11 moves towards the gear adjusting rod under the action of the pressure spring 15; if the bolt 11 is aligned with the jack 16, the bolt 11 is directly inserted into the jack 16 to complete the locking of the four-bar linkage 1; if the pin is not aligned with the jack 16 at the moment, the torsion spring resetting component 22 drives the second rod 5 and the fourth rod 7 to rotate, so that the shape of the whole four-bar mechanism 1 is changed, and the pin enters the nearest jack 16 to achieve a locking state; the bed backrest 9 can be kept stable relative to the bed frame 8 after the angle is adjusted;

4. the bed backrest 9 with the adjustable gears can give rest postures of different angles to a user and improve the large-area back support comfort level, so that the use comfort level is improved;

5. when the angle difference between the rotary gears of the bed backrest 9 needs to be adjusted, the gear control rod 10 can be fixedly installed at different positions relative to the first rod 4 through the installation nails 18, and then the angle difference between the two gears can be adjusted.
