Two-side open-close type secondary-folding mechanical attic device

Abstract

The invention discloses a two-side open-close type secondary-folding mechanical attic device and belongs to the field of building attics. The mechanical attic device is composed of two sets of oppositely-arranged attic half frame assemblies. The two sets of attic half frame assemblies are rotatably connected and designed by adopting internal and external separation layer frames correspondingly. Alinkage design of electric push rods and connecting rods is adopted by the internal and external separation layer frames. When the internal and external separation layer frames are folded, first separation layer frames are driven to overturn and fold upwards by the electric push rods of the two sets of attic half frame assemblies; in the meantime, second pulling connecting rods are pulled to movethrough sliding rods by first pulling connecting rods; second separation layer frames are driven to overturn and fold upwards twice relative to the first separation layer frames by the second pullingconnecting rods. According to the two-side open-close type secondary-folding mechanical attic device, the after-folding structure is more compact; the mechanical attic device is quite applicable to attics with larger transverse dimension; it can be achieved more effectively that the attic is folded towards two sides, and height-direction space is not occupied; besides, the mechanical attic deviceis simple in the integral structure, manufacturing is convenient, spreading and folding are convenient to control, the after-spreading structure is stable, and the bearing capacity is high.

Description

technical field [0001] The invention relates to a mechanical attic, more specifically, to a double-folding mechanical attic device with opening and closing on both sides. Background technique [0002] At present, most building attics are integral attic structures fixed together with the building. This kind of attic structure needs to occupy a large space, and is generally only arranged on the top floor; and in the case of a small living space, it is often impossible to set up an attic. [0003] With the rise of housing prices, the rational use of residential space has become a problem that many families need to consider. Many foldable furniture etc. have also been released on the market for this reason, and this class product generally adopts invisible moving methods such as hanging wall, hanging, folding to obtain partial space, but is difficult to make full use of the height space of the house. The mechanical attic is a feasible scheme that can effectively utilize the hei...

Problems solved by technology

[0006] The purpose of the present invention is to overcome the shortcomings of the existing lift-type mechanical attic, such as large floor space occupation and poor space utilization flexibility, and provide a double-folding mechanical attic device with opening and closing on both sides. By adopting the technical solution of the present invention, The mechanical attic device is composed of two sets of attic half-frame assemblies that are set opposite to each other. The two sets of attic half-frame assemblies are designed to be rotated and connected with inner and outer compartment frames. When the shelves are folded, the electric push rods of the two sets of attic half-frame assemblies drive the first shelf to flip up and fold, and at the same time, the first pull link pulls the second pull link to move through the sliding rod, and is driven by the second pull link. Compared with the first shelf, the second shelf is folded upwards for the second time. After folding, the structure is more compact. It is very suitable for attics with large horizontal dimensions, and can more effectively realize the attic folding to both sides without occupying space in the height direction. ; and the overall structure of the mechanical attic device is simple, easy to manufacture, easy to control when unfolding and folding, stable structure after unfolding, and strong bearing capacity
