Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

As shown in fig. 1 and 2, a folding lying chair includes two sets of legs 1, a seat frame 2 and a backrest 3.

The chair leg 1 comprises a chair leg 1I and a chair leg 1 II, and a fixing block 103 is connected between the chair leg 1I and the chair leg 1 II, so that a triangular structure is formed between the chair leg 1I and the chair leg 1 II to support the folding flat deck chair, and the support stability is good.

Two sides of the chair surface frame 2 are respectively fixedly connected with the two groups of chair legs 1 II.

A first hinge block 4 is sleeved between the chair back 3 and the chair face frame 2, so that the chair back 3 and the chair face frame 2 are hinged. The first hinge block 4 is also provided with a fixed rod 6, and the other end of the fixed rod 6 is hinged with the first chair leg 1.

As shown in fig. 7 and 8, an armrest 104 is hinged to the fixing block 103, and a rack 105 is bolted to the bottom of the armrest 104. The rack 105 is provided with a plurality of clamping holes 107 arranged in an array, and the clamping holes 107 are internally clamped with tooth blocks 106. The tooth block 105 is hinged with the first hinge block 4. The rack block 106 and the rack 105 are used for fixing the turning position between the chair back 3 and the chair face frame 2.

When it is desired to convert the folding chair into a folding flat recliner, the armrest 104 is pushed to allow rotation between the seat back 3 and the seat frame 2 connected to the first hinge block 4. The seat frame 2 is fixed and the toothed block 106 slides in the toothed rack 105 until the back 3 rotates flush with the seat frame 2, so that the folding chair is converted into a folding flat recliner.

The engaging holes 107 are stepped, so that the tooth block 106 can move out of the engaging hole 107 and enter the next engaging hole 107 under the action of a large external force.

Furthermore, the back side of the chair back 3 is provided with a second hinge block 7, one side of the second hinge block 7 is fixedly sleeved on the chair back 3, and the other side of the second hinge block is inserted with a support frame 8. When the foldable chair is used, the support frame 8 is rotated, so that the support frame 8 is parallel to and abutted against the chair back 3, and the space is saved. When the chair is used as a folding lying chair, the support frame 8 is rotated to form an angle of 70-110 degrees between the support frame 8 and the chair back 3. When the seat back 3 and the seat frame 2 are flush with each other, the support frame 8 abuts against the floor and serves as a support point for the seat back 3.

Furthermore, one end of the seat frame 2 is fixedly sleeved with a third hinge block 9, and the other end of the third hinge block 9 is inserted with a foot rest 10. The foot rest 10 is used for further supporting the folding chair by matching with the chair feet 1 when the folding chair is used as the folding chair, so that the supporting effect is ensured; when used as a folding lying chair, can be used as a support for placing legs and feet of a person. The middle part of the foot rest 10 is hinged with a connecting rod 11, and the other end of the connecting rod 11 is hinged with the bottom end of the chair back 3.

Wherein, the connecting rod 11 is a bent rod, and the length of the bent rod is greater than the straight line shortest distance between the chair back 3 and the foot rest 10 when the folding chair is used. The above arrangement can prevent the seat back 3 from being locked when it is rotated.

Through the above arrangement, when the chair needs to be used as a folding lying chair, the armrest 104 is pushed backwards, the tooth block 106 moves in the rack 105, so as to drive the chair back 3 connected with the armrest 104 backwards, the connecting sheet 13 drives the connecting rod 11 in the process, the foot rest 10 is pushed upwards, the purpose of adjusting the angle of the chair is achieved, when the armrest 104 is pushed to the foremost gear of the rack 105, the chair back 3, the chair seat frame 2 and the foot rest 10 are basically in a straight line, the whole chair seat can reach 180 degrees, the lying state is achieved, and at the moment, the folding chair is changed into a folding lying chair.

The specific motion state is shown in fig. 4-6.

Optimally, the middle parts of the chair back 3, the foot rest 10 and the chair face frame 2 are provided with a plurality of support rods 12, so that the chair back 3, the foot rest 10 and the chair face frame 2 are improved to support a human body when in use, and the folding chair can bear the weight of the human body.

In addition, the structure of the first hinge block 4 is shown in fig. 3, and the principles of the second hinge block 7 and the third hinge block 9 are consistent with those of the first hinge block 4. The first hinge block 4 comprises a block body 41, a first sleeve 42 is fixedly connected to the block body 41, a second sleeve 43 is hinged to the first sleeve 42, and a sleeve hole 44 used for inserting the seat frame 2 and the seat back 3 is formed in the middle of the first sleeve 42 and the second sleeve 43. When the connection is completed, the seat frame 2 is connected with the first sleeve 42, the seat back 3 is connected with the second sleeve 43, the second sleeve 43 can rotate, and the first sleeve 42 is fixed, so that the seat back 3 can rotate to be flush with the seat frame 2.
