Two-degree-of-freedom window
Technical Field
The invention belongs to the technical field of windows, and particularly provides a two-degree-of-freedom window.
Background
The window is one of the most common things in life, the design of the window needs to meet daily ventilation requirements, lighting requirements and the like, and two types of single-degree-of-freedom windows, namely a casement window and a sliding window, are the most common types in the related art. The casement window is opened and closed by rotating a certain shaft along a certain direction, and is divided into an inward opening type and an outward opening type, and has the advantages of simple structure, large opening area, good ventilation effect and good sealing property, and meanwhile, the casement window also has the defects that the inward opening type occupies indoor space, and the outward opening type is easy to damage when meeting the weather window sashes of strong wind. The sliding window has the advantages of simplicity, attractive appearance, large glass blocks, wide vision, high lighting rate and the like. The disadvantage is that two windows cannot be opened simultaneously, at most half of them can be opened, the ventilation is relatively poor, and sometimes the tightness is slightly poor.
Disclosure of utility model
The invention aims to provide a two-degree-of-freedom window, which mainly combines the characteristics of a casement window and a sliding window, is simple to operate, integrates the advantages of the two windows, and optimizes the disadvantages of the two windows.
The technical scheme of the invention is as follows:
a two-degree-of-freedom window comprises a reverse cam mechanism, a window frame and a window sash, wherein the reverse cam mechanism comprises a cam, a rotating shaft, a torsion spring, an inclined surface cross rod and a sliding seat, the rotating shaft is arranged on the sliding seat and can freely rotate on the sliding seat, a cam is fixed on the rotating shaft, the cam drives the rotating shaft to rotate when in operation, the rotating shaft is directly connected with one end of the window sash, the rotating shaft can drive the window sash to rotate, and the moving structures of the upper end and the lower end of the window sash are basically the same.
The rotating shaft is sleeved with a torsion spring which is arranged between the sliding seat and the cam.
The upper end and the lower end of the torsion spring are respectively and fixedly connected with the sliding seat and the cam, and the torsion spring is always in a compressed state due to the change of angles between the sliding seat and the cam in the movement process, so that torsion force is provided to enable the cam and the inclined surface cross rod to be always in contact with each other.
The cam is always in contact with the inclined surface cross rod in the moving process, and can automatically rotate in the moving process due to the action of the inclined surface cross rod, so that the rotating shaft is driven to rotate.
The rotating shaft can drive the window sash to rotate, so that the movement of the sliding block drives the window sash to move and rotate in two degrees of freedom, and the window is opened and closed. To ensure that the closed and open states are not affected, a self-locking mechanism may be designed separately.
The upper and lower sides of the inner side of the window frame are respectively provided with a sliding rail for the sliding of the sliding seat.
Two V-shaped guide rollers are arranged on each sliding seat and can slide on the sliding rail.
The two sides of the window sashes are provided with the sliding seat up and down, and meanwhile, the bottom sliding seat is provided with the handle, and the sliding seat is moved by the force acted on the handle, so that the window can be opened and closed.
The curve shape of the cam can be designed to bring different rotation angular velocities to the cam, namely the window sash, when the slide seat slides.
The invention has the beneficial effects that the invention mainly combines the characteristics of a side-hung type window and a push-pull type window, designs a new structure on the basis of the two structures, and has the effects of two windows. The whole window is realized moving through the structure of the sliding window, so that the casement window effect is achieved. The window has the advantages of simplicity, attractive appearance, wide visual field and high lighting rate compared with the sliding window, and simultaneously has the advantages of large opening area, good ventilation and good sealing performance compared with the sliding window, and the problem that the outward opening in the sliding window is easy to damage on a windy day and the inward opening occupies the indoor space is considered.

Detailed Description
Referring to fig. 1 to 8, a two-degree-of-freedom window comprises a reverse cam mechanism, a window frame 1 and a window sash 2, wherein the reverse cam mechanism comprises a cam 6, a rotating shaft 8, a torsion spring 5, an inclined surface cross bar 3 and a sliding seat 7 as shown in fig. 6.
As shown in fig. 6, 7 and 8, the sliding seat 7 is provided with a rotating shaft 8, the rotating shaft 8 can freely rotate on the sliding seat 7, a cam 6 is fixed on the rotating shaft 8, the rotating shaft 8 is driven to rotate by the cam 6 during operation, a torsion spring 5 is sleeved on the rotating shaft 8 and is arranged between the sliding seat 7 and the cam 6, the upper end and the lower end of the torsion spring 5 are respectively fixed with the sliding seat 7 and the cam 6, and the torsion spring 5 is always in a compressed state due to the change of an angle between the sliding seat 7 and the cam 6 during movement, so that a counterclockwise torsion force is always provided to act on the cam 6, the cam 6 and the inclined cross rod 3 are always in contact with each other, the rotating shaft 8 is directly connected with the window sash 2, and the rotating shaft 8 can drive the window sash 2 to rotate.
When the window is closed, namely the sliding seat 7 drives the rotating shaft 8 to horizontally move from left to right, the cam 6 always contacts the inclined surface cross rod 3 in the moving process under the action of the torsion spring 5, the cam 6 slowly rotates clockwise in the moving process from left to right due to the action of the inclined surface cross rod 3, meanwhile, the cam 6 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the window sash 2 to rotate, so that the movement of the sliding seat 7 drives the window sash 2 to move and rotate in two degrees of freedom as shown in fig. 3, 4 and 5 is realized, and when the window is required to be opened, the sliding seat 7 is driven to move from right to left as in the action of the above process, and the window is opened by the same movement mechanism as that of the window when the window is required to be opened.
As shown in fig. 6 and 8, the inside of the window frame 1 is provided with a sliding rail 10 for sliding the sliding seat 7 up and down, respectively. Two V-shaped guide rollers 9 are provided on each carriage 7 to allow it to slide on a rail 10.
As shown in fig. 7, the two side window sashes 2 are provided with a sliding seat 7 up and down, and the bottom sliding seat 7 is provided with a handle 4, and the sliding seat 7 is moved by the force acting on the handle 4, so that the window can be opened and closed.
The cam 6 can be designed to have a curved shape that gives different rotational angular velocities to the cam 6, i.e. the window sash 2, when the slide 7 slides.
