Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of windows, and in particular provides a two-degree-of-freedom window. Background Art
[0002] Windows are one of the most common things in life. The design of windows needs to meet the daily ventilation and lighting needs of life. In the relevant technology, the most common types are two single-degree-of-freedom windows: casement windows and sliding windows. Casement windows are opened and closed by rotating along a certain axis in a certain direction. They are divided into two types: inward-opening and outward-opening. They have the advantages of simple structure, large opening area, good ventilation effect, and good sealing. At the same time, they also have the disadvantages that the inward-opening type will occupy indoor space, and the outward-opening type is easy to be damaged in windy weather. Sliding windows are windows that are installed in the track of the window frame and pushed and pulled to open and close. The advantages are simplicity, beauty, large glass blocks, wide field of view, high lighting rate, etc. The disadvantage is that the two windows cannot be opened at the same time, and can only be opened half at most, the ventilation is relatively poor, and sometimes the sealing is also slightly poor. Utility Model Content
[0003] The purpose of the present invention is to provide a two-degree-of-freedom window, which mainly combines the characteristics of a casement window and a sliding window, is easy to operate, and not only combines the advantages of the two windows, but also optimizes the disadvantages of the two windows.
[0004] The technical solution of the present invention is as follows:
[0005] A two-degree-of-freedom window comprises an inverse cam mechanism, a window frame, and a window sash; wherein the inverse cam mechanism comprises a cam, a rotating shaft, a torsion spring, an inclined cross bar, and a sliding seat; the sliding seat is provided with a rotating shaft, which can rotate freely on the sliding seat, and a cam is fixed on the rotating shaft. When working, the cam drives the rotating shaft to rotate, and at the same time, the rotating shaft is directly connected to one end of the window sash, so that the rotating shaft can drive the window sash to rotate, and the motion structures at the upper and lower ends of the window sash are basically the same.
[0006] A torsion spring is sleeved on the rotating shaft and is located between the sliding seat and the cam.
[0007] The upper and lower ends of the torsion spring are fixedly connected to the slide and the cam respectively. Due to the change in the angle between the slide and the cam during movement, the torsion spring is always in a compressed state, thereby providing a torsional force to keep the cam and the inclined crossbar in contact with each other.
[0008] The cam is always in contact with the inclined cross bar during the movement. Due to the effect of the inclined cross bar, the cam will automatically rotate during the movement, thereby driving the rotating shaft to rotate.
[0009] The rotating shaft can drive the window sash to rotate, so that the movement of the slider drives the window sash to move and rotate in two degrees of freedom, thereby realizing the opening and closing of the window. In order to ensure that the closing and opening states are not affected, a self-locking mechanism can be designed separately.
[0010] The upper and lower inner sides of the window frame are respectively provided with slide rails for the slide seat to slide.
[0011] Each slide seat is provided with two V-shaped guide rollers to enable it to slide on the slide rail.
[0012] The two window sashes are provided with sliding seats at the top and the bottom, and a handle is provided at the bottom of the sliding seat. The sliding seat is moved by applying force on the handle, so that the window can be opened and closed.
[0013] The curve shape of the cam can be designed so that the cam, i.e. the window sash, can have different rotational angular velocities when the slide seat slides.
[0014] The beneficial effects of the present invention are as follows: it mainly combines the characteristics of casement type and sliding type, and designs a new structure based on the structures of the two, which has the effects of two windows. The overall movement of the window is achieved through the structure of the sliding window, so that the window sash can achieve the effect of the casement window. It combines the advantages of sliding windows and casement windows and has the advantages of both windows, that is, it has the advantages of simplicity, beauty, wide field of vision and high daylighting rate compared to sliding windows; it also has the advantages of large opening area, good ventilation and good sealing compared to casement windows; considering the problem that the outward-opening type of casement windows is easily damaged on windy days and the inward-opening type occupies indoor space, the present invention has a structure that occupies half of the area of the window sash both indoors and outdoors, thereby reducing the indoor space occupied by the inward-opening type, and also reducing the problem of large force area on windy days compared to the outward-opening type, that is, easy to be damaged by excessive wind load.

[0024] Reference Figures 1 to 8 A two-degree-of-freedom window comprises an inverse cam mechanism, a window frame 1, and a window sash 2, wherein the inverse cam mechanism is as follows Figure 6 The structure shown in the figure includes a cam 6, a rotating shaft 8, a torsion spring 5, an inclined cross bar 3, and a sliding seat 7.
[0025] like Figure 6 , Figure 7 and Figure 8 As shown, the slide 7 is provided with a rotating shaft 8, and the rotating shaft 8 can rotate freely on the slide 7. A cam 6 is fixed on the rotating shaft 8. When working, the cam 6 drives the rotating shaft 8 to rotate. At the same time, a torsion spring 5 is sleeved on the rotating shaft 8, which is between the slide 7 and the cam 6. The upper and lower ends of the torsion spring 5 are respectively fixed to the slide 7 and the cam 6. Due to the change of the angle between the slide 7 and the cam 6 during the movement, the torsion spring 5 is always in a compressed state, thereby always providing a counterclockwise torsional force acting on the cam 6, so that the cam 6 and the inclined cross bar 3 are always in contact with each other; the rotating shaft 8 is also directly connected to the window sash 2, and the rotating shaft 8 can drive the window sash 2 to rotate.
[0026] like Fig. 9 As shown, when opening or closing the window, it is only necessary to manually act on the handle 4 to drive the bottom slide 7 to move through the handle 4; when closing the window, the slide 7 drives the rotating shaft 8 to move horizontally from left to right, and the cam 6 is always in contact with the inclined cross bar 3 during the movement under the action of the torsion spring 5. Due to the action of the inclined cross bar 3, the cam 6 slowly rotates in the clockwise direction during the movement from left to right, and at the same time, the cam 6 drives the rotating shaft 8 to rotate, and then the rotating shaft 8 drives the window sash 2 to rotate, thereby achieving the following Figure 3 , Figure 4 , Figure 5 As shown, the movement of the slide 7 drives the movement and rotation of the window sash 2 in two degrees of freedom, thereby achieving the closing of the window; when the window needs to be opened, the handle 4 is manually acted on as in the above process to drive the slide 7 to move from right to left, and its movement mechanism is the same as when closing, thereby achieving the opening of the window.
[0027] like Figure 6 and Figure 8As shown, the inner side of the window frame 1 is respectively provided with slide rails 10 for the slide seat 7 to slide. Each slide seat 7 is provided with two V-shaped guide rollers 9 to enable it to slide on the slide rails 10.
[0028] like Figure 7 As shown, both window sashes 2 have slide seats 7 at the top and bottom, and the bottom slide seat 7 is provided with a handle 4. The slide seat 7 is moved by the force acting on the handle 4, so that the window can be opened and closed.
[0029] The curved shape of the cam 6 can be designed so that the cam 6 and the window sash 2 can have different rotational angular velocities when the slide seat 7 slides.
[0030] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
