Detailed ways

The present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments: Referring to FIGS. 1 to 6 , the multifunctional walking aid reclining chair includes a bottom plate 1, and a seat cushion 2 is provided on the bottom plate 1 by sliding. The bottom plate 1 is provided with a linear guide rail, and the seat cushion 2 is provided with a sliding block, and the sliding block is slidably matched with the linear guide rail. A backrest 3 is rotatably arranged on one side of the seat cushion 2, and an armrest 4 is arranged on the backrest 3. One end of the armrest 4 is hinged with the backrest 3, and the other end of the armrest 4 is rotatably provided with a connecting rod 5. The connecting rod 5 is rotatably connected with the seat cushion 2 . A telescopic rod 6 is fixedly arranged on the bottom plate 1 , and one end of the telescopic rod 6 is fixedly connected with the lower end of the handrail 4 .

In the above structure, the backrest 3, the armrest 4, the seat cushion 2 and the connecting rod 5 form a parallelogram structure. When the angle of the backrest 3 is adjusted backwards, since the telescopic rod 6 is fixed with the armrest 4 and the bottom plate 1, the armrest 4 can only be To move up and down, under the constraint of the linear guide 5, the seat cushion 6 can move forward in translation. This kind of device takes into account the influence of the change of the lying angle on the center of gravity. When the lying angle is larger, the amount of forward translation is greater; on the contrary, when the human body sits upright, the center of gravity moves backward, ensuring that the center of gravity is always on the chair. Center, which guarantees reliability when lying flat.

In addition, the left and right sides of the parallelogram formed by the connection point between the armrest and the backrest, the connection point between the backrest and the seat cushion, the rotation point of the armrest, and the connection point of the armrest and the seat cushion are close to vertical at the beginning, so as to prevent the armrest from moving forward when the seat cushion moves forward. up and down trend. Different from taking the connection point of the backrest and the seat cushion as the center of the circle, the center of the device is taken to the connection point of the armrest and the backrest, using the property that the hypotenuse of a right-angled triangle must be larger than the right-angled side, so that the armrest only moves downward, and the upper and lower sides are compressed and inclined. The angle between the side and the upper side gradually becomes smaller, so that the seat cushion gradually extends forward.

A locking mechanism 8 is provided between the bottom plate 1 and the seat cushion 2 . The locking mechanism 8 includes a gas spring 80 , and the front end of the gas spring 80 is fixedly connected to the lower side wall of the seat cushion 2 through a front end connecting block 81 . , the rear end of the gas spring is fixedly connected to the bottom plate 1 through the rear end connecting block 82, and a lock switch 83 is provided on the armrest, and the lock switch 83 passes through the rolling line (not shown in the drawings) Connected to the gas spring 80, when a person needs to lie back, they can turn the lock switch and pass the rolling wire to lie back. If the switch is released on the way, the angle can be stuck, and the gas spring will push the seat back to its original position after getting up and flipping the switch.

The telescopic rod 6 includes an upper fixing sleeve 60 and a lower fixing sleeve 61, the upper fixing sleeve 60 is fixed with the lower end of the handrail 4, the lower fixing sleeve 61 is fixed with the bottom plate 1, and is fixed at the bottom. The lower fixed sleeve 61 is provided with an automatic adjustment rod 65, and the upper fixed sleeve 60 is provided with a manual adjustment rod 62, and the lower end of the manual adjustment rod 62 is abutted against the push rod part 62a and some inclined blocks 63. , a lock rod 64 is provided on the fixed sleeve 60, one side of the lock rod 64 is provided with a spring (not shown in the drawings) that elastically pushes the lock rod 64, and the lock rod 64 is provided with a The inclined surface 64a of the inclined block 63 is provided with a locking hole on the automatic adjustment rod 65 which is matched with the locking rod 64 (not shown in the drawings).

The manual adjustment rod 1 is hidden in the armrest groove 100 . The above-mentioned telescopic rod can adjust the force angle according to the height of the elderly. In the walking assistance mode, the distance between the hands of the elderly and the ground is 80cm-90cm, which is in line with the actual walking assistance height. The inside of the manual adjustment rod relies on the spring to push the lock rod out of the lock hole to fix the height. When you want to change to the sitting and lying mode, you only need to press the switch to generate a downward pressure, and the downward pressure will be converted into a horizontal squeeze through the inclined block 7. Press the lock lever back, so that the lever can be retracted into the armrest slot.

A walking aid mechanism 7 is fixedly arranged on the base plate 1 , and the walking aid mechanism 7 includes a bending pipe 70 , a brake wheel 71 , and a directional wheel 72 , wherein the brake wheel 71 includes a pulley 710 and a brake matched with the pulley. The mechanism 711 is used to lock the pulley by pressing the brake mechanism with the foot. In this application, the brake mechanism includes a positioning column 711a, and a cavity 711b opposite to the rotation axis of the pulley is provided on the positioning column 711a. A spring is arranged in the cavity 711b, and a positioning cap 711c is arranged at the upper end of the spring. By stepping on the positioning cap 711c with a foot, the spring is pressed down, so as to increase the damping between the spring and the rotating shaft of the pulley, Then, the pulley is locked. Of course, the brake mechanism in this application can also adopt other well-known pedal brake mechanisms, and the above structure will not be repeated in this application. The directional wheel 72 adopts a universal wheel, so that the whole reclining chair can move in a free direction.

The seat cushion 2 includes a seat cushion body 20 and a cover plate portion 21. A notch portion is provided at the front end of the seat cushion body 20, and a cover member 21 is rotatably arranged on the notch portion through a loose leaf (not marked in the drawings). The above structure, in When using the walking mode, by flipping the cover member 21 upwards, the user can hold the armrest with both hands to move conveniently, and since the notch on the main body of the seat cushion is facing the user at this time, the user can easily move. It is not easy for the legs to touch the seat cushion 2.

The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions in this application are only the principles of the present invention, and there will be various changes and improvements in the present invention without departing from the spirit and scope of the present invention.
