Detailed Description

The invention will be further explained with reference to the drawings:

as shown in fig. 1-6, a convertible wheelchair of table suitable for heart failure patient, includes the wheelchair body, includes front wheel 6 and rear wheel 5 on the whole support of wheelchair body 1, and whole support the place ahead is equipped with pedal 7, and the rear is equipped with and pushes away handle 3, its characterized in that: both sides are equipped with handrail 2 on the monolith support, handrail 2 is top open-ended square cavity structure, installation pivot 8 in the square cavity upper right corner, be equipped with around the rotatory cover body 12 of pivot in the middle of the pivot 8, be hinge axle 9 on the cover body 12, be equipped with around the rotatory hinge cover body 10 of hinge axle 9 in the middle of the hinge axle 9, hinge cover body 10 end is hinge piece 11, and the end ear 13 of table 4 is connected to hinge piece 11, the table 4 is put into square cavity's handrail after two rotations of pivot 8 and hinge axle 9.

The opening of the handrail 2 is provided with a cover body which is hinged at the opening. The hinge plate 11 is connected with the end lug 13 of the desk plate 4 through a bolt or a rivet. The table plates 4 in the armrests 2 on the two sides are butted after being unfolded. The tail end of the hinge shaft 9 is provided with a limit stop 14 which can limit the horizontal placement of the table board. The table plate is made of plastic materials.

Example (b):

as shown in figure 1, when a heart failure patient sits on a wheelchair and needs to meet the posture that the upper body of the patient leans forward, the table plates in the armrests on the two sides are pulled out and horizontally placed in front of the patient after twice rotation, and the patient can lie on the wheelchair or lean forward through the upper limb support.

The principle of the rotation of the table plate is as follows: the table shown in fig. 2 is placed in a square cavity handrail with an opening at the upper part, the table is lifted out by hands, the table is rotated clockwise around a rotating shaft 8 in the process of lifting out the table, the table completely comes out of the square cavity handrail when the table is rotated by 180 degrees, as shown in fig. 3, the table and the square cavity handrail are positioned on the same horizontal plane, then, the vertical rotation is realized through a hinge shaft 9, fig. 4 shows the overturning state of the table, the table is in a vertical state with the handrail at the moment, and a limit stop 14 at the tail end of the hinge shaft 9 can limit the horizontal placement of the table and prevent the table from rotating.

Fig. 5 shows specific relationship among the structures in the above embodiment, the rotating shaft 8 is disposed between the square hollow handrail with an opening at the top, the rotating shaft 8 and the hinge shaft 9 form a T-shaped structure, and the hinge sleeve 10 in the middle of the hinge shaft 9 rotates around the hinge shaft 9 to drive the table to rotate.

The above description is the preferred embodiment of the present invention, and for those skilled in the art, modifications of the various equivalent forms of the present invention are within the scope of the appended claims of the present application without departing from the principle of the present invention.
