Description

Rapid and safe deformation chair

Technical Field

The utility model belongs to the technical field of the chair technique of warping and specifically relates to a can become the deck chair from the seat fast as required, become the chair warp of seat from the deck chair.

Background

The types of the known chairs are various, and the types of the deformed chairs are single and similar in structure. The disclosed convertible or utility chair is merely an improvement in the reclining angle of the backrest, enabling the chair to be converted into a lounge chair. However, simply changing the back-tilt angle of the backrest will inevitably damage the balance of the chair, or the chair will lose balance during use, causing the chair to tip over and hurt the body.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: in order to overcome the problem that the chair is deformed into the unbalanced gravity center behind the deck chair, the utility model provides a new technical scheme, no matter make the chair be in the seat state, the deck chair state or the human body is in the position of sitting or the appearance of lying, all possess the gravity center balance, and the deformation process of chair is rapid and steady moreover. In addition, a back massage device is added to massage the back of the human body in the process of repeatedly leaning back.

The utility model provides a technical scheme that its technical problem adopted is: a rapid and safe deformable chair comprises a support, a backrest, a cushion, leg supports, pull rods, a mechanical massage device and a tension device, wherein the support is provided with a front end cross beam and a rear end cross beam, the left end and the right end of the support are also provided with armrests, the front end of the cushion is fixedly arranged on the front end cross beam through a limiting groove, the leg supports are connected to the front end of the cushion through hinges, the rear end of the cushion is connected with the backrest through hinge shafts, the backrest is connected to the rear end cross beam through the mechanical massage device, the mechanical massage device elastically supports the backrest, the pull rods are connected between the two ends of the hinge shafts and the two armrests on the corresponding two sides through hinge connection modes, the tension device is further arranged below the backrest and the cushion on the support, the backrest, the cushion and the pull rods are three-in-one, when a human body leans backwards, the backrest and the cushion droop and deform into a reclining chair state under the action of gravity center displacement, and when the human body sits forwards, the backrest and the cushion change into a chair state under the action of gravity center displacement;

furthermore, the mechanical massage device of the utility model comprises a massage wheel support and a massage wheel arranged on the massage wheel support, the massage wheel support is hinged on the rear end beam through a left torsion spring piece and a right torsion spring piece (the elasticity of the support is enhanced, the torsion angle of the support is increased, so that the backrest is supported on the chair support when the deformation chair is changed into a deck chair), the massage wheel elastically supports against the backrest under the action of the torsion spring pieces, and the massage wheel and the surface of the backrest move relatively in the rotation process of the backrest to generate a rolling massage effect on the back of a human body;

furthermore, the tensioning device of the utility model consists of a spring, a stay cord and a spring cylinder, one end of the spring is fixed in the spring cylinder, the other end is connected with the stay cord, the other end of the stay cord is connected with a hinge connected with the backrest and the cushion, and the tensioning device is used for tensioning the front cushion of the seat deformation deck chair, cushioning the sagging force during deformation and tensioning the deck chair when the seat is restored;

furthermore, the leg support of the utility model is vertically fixed at the front end of the cushion, and when the chair is transformed into a deck chair, the leg support is used for supporting the position of the crus; and the leg support has a limiting function when the chair is in a seat state;

furthermore, the limiting groove of the utility model is arranged at the bottom of the front end of the cushion, the limiting groove is an arc structure matched with the cylindrical surface of the front end beam, and the seat is clamped on the front end beam when in a state, so that the cushion is prevented from moving back and forth; when the chair deforms, the limiting groove changes along with the cushion, when a certain angle is reached, the limiting groove passes over the cross beam, and the cushion slides and moves on the cross beam;

the utility model has the advantages that: the utility model changes the conventional fixed structure of the traditional chair, positions the cushion by the support bar and the pull bar, and adjusts the posture of the cushion by the angle of the pull bar; the adjacent sections of the back cushion and the cushion are connected through the hinge, the change of the angle of the cushion is restrained while the backrest is ensured to freely lean backwards, and the posture changes of the cushion and the back cushion are more coherent and stable. In addition, the tensioning device is additionally arranged, so that the seat can play a role of buffering and resetting in the process of deforming into a deck chair and deforming into the seat, and meanwhile, the comfort is enhanced and the mechanical feeling is reduced in the deformation process. Finally, the backrest is additionally provided with an elastic mechanical massage device, so that the human body can rotate backward through the backrest and generate positive pressure rolling with the massage wheel, and the massage effect is achieved on the back of the human body.
