Abstract

The utility model relates to a multifunctional sofa which can be automatically transformed. The main structure of the utility model is that a handrail has a sleeved frame structure which can be expanded or contracted. The handrail is composed of a fixed framework (or a fixed plate), an elevating framework sleeved outside the fixed framework and an automatic elevating device (comprising a mechanical type, a hydraulic type, a pneumatic type, etc.). The automatic elevating device is arranged on a horizontal top plate of the fixed framework, and a stressing point of the elevating device is connected with the elevating framework by the orientation way. The elevating framework rises or falls with the elevating device, that is, a handrail rises or falls automatically, and a chair angle adjusting device adjusts the angle when the handrail is used for a backrest. A base and the backrest rise and fall automatically with the same method, the angle of the backrest is adjustable. The other handrail of the sofa is separated from the same plane of the base and divided into an upper and lower sections, the upper and lower sections are articulated outside the handrail. The upper part of the handrail is fastened to a hinge rotating shaft, and one end of the rotating shaft is provided with a decelerating motor. The upper part of the handrail can be overturned outward 180 degrees automatically, and the base of the sofa can be extended forth. After the use, the soft can turn inward and fold automatically. The handrail can be transferred into the backrest with the adjustable angle automatically. The base and the backrest can be risen or fallen automatically, and the base can be extended outward so as to achieve the automatic deformation and multi-functionalization of the sofa.

Can be from the multifunction sofa of dynamic deformation

Technical field

The utility model relates to a kind of sofa, especially a kind of sofa handrail energy automatic lifting and adjustable angle, another sofa handrail can outwards launch to increase pedestal length and backrest automatically can automatic lifting and adjustable angle, the multifunction sofa that pedestal also can automatic lifting.

Background technology

At present, the handrail of general sofa is fixed, and when people need be placed on the bed rest of sofa seat epibasal half to leg, because the insufficient height and the angle of sofa handrail are non-adjustable, people can't lean on and carry out the angular adjustment of the most comfortable; When people need put down when being recumbent on a sofa rest, often the length of sofa pedestal is not enough; The height of people's door is different, and the backrest and the pedestal of general sofa are fixed, and when people need adjust to best seated resting, backrest and pedestal all can not be adjusted, so present general sofa can not satisfy people's comfortable needs that lie fallow far away.

The utility model content

The purpose of this utility model is:

At the changeless defective of general sofa handrail height, the sofa that provides a kind of handrail height can be as required can automatic lifting to regulate, make people sofa first when for sleeping in, sofa handrail can raise automatically and become backrest, can descend automatically after using up becomes handrail or pillow.

At the changeless defective of general sofa handrail height, provide a kind of handrail not only can carry out automatic lifting as required and regulate, and can also carry out the sofa of angular adjustment when after rising, doing backrest.

Fix at general sofa handrail, can not launch to increase the defective of sofa pedestal length automatically, the sofa that provides a kind of handrail can outwards launch to increase pedestal length automatically, when making people lie low extendable legs rest in the above, the sofa pedestal has enough length.

Backrest and pedestal at general sofa all are the defectives of fixing, and the sofa that provides a kind of backrest and pedestal to adjust makes people's sitting posture be adjustable to optimum state.

The purpose of this utility model is achieved in that and a kind ofly can comprises pedestal from the multifunction sofa of dynamic deformation, backrest, handrail, it is characterized in that: handrail has fixed frame (or fixed head) and is enclosed within the outer lifting frame of fixed frame, apparatus for automatically lifting (comprises mechanical type, fluid pressure type, pneumatic type etc.) form, the end head that fixed frame is fixedly connected on pedestal is used to install the position of handrail or fixes corresponding position on the ground, apparatus for automatically lifting is installed on the horizontal top board of fixed frame or on the ground, the lifting point of application of apparatus for automatically lifting positions with lifting frame and is connected, lifting frame just carries out lifting with the lifting of apparatus for automatically lifting, there is the moulding of a sofa handrail outside of lifting frame, the automatic lifting of lifting frame is the automatic lifting of handrail, thereby realize becoming backrest after handrail raises automatically, become handrail or pillow after falling.

A kind ofly can comprise pedestal, backrest, handrail from the multifunction sofa of dynamic deformation, it is characterized in that: sofa handrail disconnects at the place, same plane with the pedestal seat surface, be divided into two parts up and down, the first half and Lower Half are carried out hinged in the handrail outside, the first half can outwards turn over turnback and launch, make sofa pedestal extend outwards, the shared axis of the hinge at first half handrail and Lower Half handrail two ends is done rotating shaft, torsion spring is arranged in the rotating shaft, the strength that struts by torsion spring when first half handrail is turned up is laborsaving, can play damping action when turning in the first half handrail again.

As further improvement of the utility model, the utility model also can replenish following architectural feature:

What play the guiding role when pair lifting frame lifting is arranged on lifting frame and the fixed frame (or fixed head) joins and installs (as: guiding such as guiding slot type or guide slit formula or fairlead tubular type or guiding linear motion bearing are joined and installed), can make two vertical arms of lifting frame remain the parallel lifting of carrying out, thereby realize the steady lifting of sofa handrail with two vertical arms of fixed frame.
