When the footrest mechanism stretches to the maximum position, it drives the limit nail on the L-shaped seat plate to continue to move upwards, and at this moment, the lifting of the seat plate can be realized, and at the same time, the backrest begins to tilt. Press the electric switch, the electric push rod retracts and drives the driving member to move, the seat plate mechanism returns to the initial position under the action of its own gravity and the driving force of the motor, and fits with the limit nail on the fixed seat frame, and the backrest also returns to the original position. previous position. Afterwards, under the action of the motor push rod, the footrest mechanism continues to be retracted, the seat plate is moved in translation, and the backrest moves to the left close to the level. When the second connecting rod fits with the limit nail on the first connecting rod, the motor push rod also returns to the original position at this moment.

The beneficial effects of the present invention are reflected in: the functions of lifting the foot rest, lifting the seat plate, and reclining the backrest can be realized separately, which enhances the comfort, the structure is simple and stable, the operation is convenient, the cost is low, and the practicability is high, which provides a solution for people's leisure problems. huge help.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

Referring to Figures 1 to 6, an iron frame mechanism for a split push chair includes a fixed seat frame 11 and a footrest mechanism 1, the fixed seat frame 11 is fixed on the wooden frame 5 of the chair, and the fixed rod 4 is fixed on the wooden frame of the chair. On the frame 5, a telescopic drive device is installed on the fixed rod 4, the telescopic end of the telescopic drive device is installed in the middle part of the power push rod 6, and a left-right symmetrical footrest mechanism 1, seat Board mechanism 2 and backrest mechanism 3, said seat plate mechanism 2 includes L-shaped seat plate 2.7, said L seat plate 2.7 includes a transverse section and a vertical section, said footrest mechanism 1 is connected to the left end of said transverse section, The upper end of the vertical section is connected with the backrest mechanism 3, the backrest mechanism 3 is connected with the upper end of the vertical strut 3.2, the lower end of the vertical strut 3.2 is hinged with the right end of the fixed seat frame 11, and the power push The end of rod 6 is connected with footrest mechanism 1, and described footrest mechanism 1 is connected with the upper end of first push rod 2.1, and the lower end of described first push rod 2.1 is hinged on the left end of described fixed seat frame 11, and the second The lower ends of the push rod 2.3 and the third push rod 2.4 are respectively hinged in the middle of the fixed seat frame 11, and the long drive rod 2.2 is connected with the upper end of the first push rod 2.1, the upper end of the second push rod 2.3 and the third push rod respectively. The middle part of the rod 2.4 is hinged, the long transmission rod 2.2 is parallel to the fixed seat frame 11, the upper end of the third push rod 2.4 is hinged with the lower end of the second transmission rod 2.5, and the upper end of the second transmission rod 2.5 It is hinged at the angle with the L-shaped seat plate 2.7.

Further, the footrest mechanism 1 includes a first connecting rod 1.2, a second connecting rod 1.4, a third connecting rod 1.5, a fourth connecting rod 1.6, a footrest pad 1.1 and a small footrest piece 1.3, the first connecting rod 1.2, the second connecting rod 1.4, the third connecting rod 1.5, and the fourth connecting rod 1.6 constitute a quadrilateral mechanism, the first connecting rod 1.2 and the second connecting rod 1.4 are connected to the two ends of the footrest 1.1 and the small footrest 1.3 Hinged respectively in the middle of the first connecting rod 1.2 and the middle of the second connecting rod 1.4, the right end of the third connecting rod 1.5 is hinged with the left end of the transverse section, the right end of the fourth connecting rod 1.6 is hinged with the transverse section The left section is hinged, and the middle part of the fourth connecting rod 1.6 is fixedly connected with the end of the power push rod 6 .

Preferably, the fixed seat frame 11 is provided with a first stop nail for limiting the travel of the first push rod and the third push rod.

The second connecting rod 1.4 is provided with a second stop nail that limits the stroke of the third connecting rod.

The left end of the L-shaped seat plate 2.7 is provided with a third stop nail for limiting the stroke of the fourth connecting rod.

The telescopic driving device is an electric telescopic mechanism. Of course, other driving modes are also possible.

The working process of the split-translational iron frame mechanism of the present invention is as follows: first, the footrest mechanism 1 stretches out and the seat plate 2 moves in translation. The nails fit together and the chair is in its original state. Press the electric switch, and the electric push rod stretches forward, thereby driving the motor to push the rod 6 to move upwards and simultaneously push the first connecting rod 2.2 of the footrest mechanism. When the footrest mechanism 1 is stretched out, it is driven The L-shaped seat plate 2.7 translates backward, and now the backrest 3.1 performs a horizontal approximate translation movement, and the angle between the backrest 3.1 and the L-shaped seat plate 2.7 remains basically unchanged. And under the gravitational effect of people, the first push rod 2.1 and the second push rod 2.3 still fit with the first limit nail on the fixed seat frame 11, the L-shaped seat board does not lift, and the backrest angle has no obvious change.

Secondly, the footrest mechanism 1 continues to lift. When the first connecting rod 1.2 is in contact with the third limit nail on the left end of the L-shaped seat plate 2.7, the power push rod 6 continues to be pushed, and the first connecting rod 1.2 drives the L-shaped seat plate. Plate 2.7 begins to lift, and L-shaped seat plate 2.7 begins to move upwards, and the first push rod 2.1, the second push rod 2.3, the third push rod 2.4 and the long transmission rod 2.2 connected thereto form a parallelogram, and the motor push rod 6 Under the driving action, the L-shaped seat plate 2.7 is supported to keep it stable. When the backrest 3.1 fits with the fourth limit nail on the support rod 3.2, at this moment, the L-shaped seat board rises to the highest position.

Finally, press the motor switch, first under the action of human gravity, because the foot rest mechanism 1 has a certain resistance to retract, the seat plate mechanism 2 first returns to lower, when the L-shaped seat plate returns to the first horizontal position, the first Push rod 2.1 and the 3rd push rod 2.4 fit with the first limit nail on the fixed seat plate 11, at this moment, the footrest mechanism just can slowly reclaim, and the backrest moves left, gets back to original state.

The iron frame mechanism of the split horizontal push chair of the present invention can be applied to office leisure, home use or other leisure occasions.
