Description

Technical Field

[0001] The present invention relates to the technical field of inward-opening windows, and particularly to a folding inward-opening window. Background Art

[0002] Due to the defects that when the window is outward-opening, the window body is easily damaged, and when a child opens the window, it is easy to cause a fall from a building, etc., the inward-opening window method has gradually become the mainstream window-opening method in China.

[0003] However, when a relatively large window opening area is required, such as when two window bodies need to be opened, the existing window bodies need to be opened separately on both sides. Then, on both sides of the indoor window body, there will be interference between the opened fan frames and the utensils placed indoors, which greatly increases the occupancy of the inner space of the house by the opened window sashes, and further greatly reduces the space utilization rate of the inner side of the house. Summary of the Invention

[0004] The purpose of the present invention is to provide a folding inward-opening window to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A folding inward-opening window includes a window frame, a handle, a first fan frame, and a second fan frame. Both the first fan frame and the second fan frame are composed of two first shells and two second shells. The two first shells and the two second shells enclose a rectangle. The first shells and the second shells are adjacent to each other. A column is arranged inside the window frame. Telescopic tie rods are arranged at both ends of the column. A handle for driving the telescopic movement of the tie rods is arranged on the column. First roller chutes are arranged at the top and bottom inside the window frame on the inner side. Both the first fan frame and the second fan frame can slide along the first roller chutes and can rotate relative to the window frame. One side of both the first fan frame and the second fan frame is hinged to the column through a hinge. After the first fan frame and the second fan frame are opened, they can be folded with the column as the intermediate member and lean against any place inside the window frame.

[0007] Rolling units corresponding to the first roller chutes one by one are arranged on both the first fan frame and the second fan frame. The rolling unit includes a housing and a sphere. The housing is connected to the first fan frame / second fan frame. The housing is slidably connected to the first roller chute. A sphere that can rotate 360° is arranged inside the housing. A part of the sphere protrudes from the housing and is in rolling connection with the first roller chute.

[0008] Positioning plates are integrally formed on both the first shell and the second shell. The four positioning plates enclose a rectangle.

[0009] An installation plate is arranged on one side of the first shell close to the window frame. A rain brush is arranged on the installation plate.

[0010] On both sides of the first roller chute, a second roller chute is provided. The rolling unit can be switched between the first roller chute and the second roller chute. After the first sash frame and the second sash frame are opened, the upright post can be retracted inside the window frame.

[0011] A notch is provided between the first roller chute and the second roller chute. The notch includes an arc segment and two straight segments. The distance between the two straight segments is the same as the outer shell, and the diameter of the arc segment is the same as the diameter of the sphere.

[0012] The beneficial effects of the present invention are:

[0013] 1. With the settings of the rolling unit, the upright post, the handle and the pull rod, the first sash frame and the second sash frame can be folded and leaned against any place inside the window frame with the upright post as the intermediate member after being opened. In the case of the same window opening area and for inward-opening windows, the space occupied inside the house after the window is opened can be greatly reduced, so that there is no need to consider the interference between the opened side sash windows and utensils during the interior layout of the house.

[0014] 2. With the settings of the second roller chute and the notch, the first sash frame and the second sash frame can be switched in different chutes, and the upright post can be retracted inside the window frame, further greatly reducing the space occupied by the sash windows in the room. For example, it can avoid the situation that children or people of short stature may accidentally bump into the opened sash windows and cause physical injuries when moving indoors.

[0015] 3. With the settings of the first roller chute and the second roller chute, the water leaking from the window will gather at the bottom end of the first roller chute and be blocked by the edge of the first roller chute, preventing water from entering the room.

[0016] 4. The setting of the windshield wiper improves the sealing performance of the window when it is closed. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0034] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0035] Embodiment 1

[0036] Please refer to Figures 1 to 13 , a folding inward-opening window is provided in the first embodiment of the present invention. Refer to Figure 1, including a window frame 1, a handle 3, a first window frame 4 and a second window frame 5. The first window frame 4 and the second window frame 5 are both composed of two first shells 12 and two second shells 11. The two first shells 12 are the left and right shells, and the two second shells 11 are the upper and lower shells. The two first shells 12 and the two second shells 11 enclose a rectangle.

[0037] There is a column 2 arranged inside the window frame 1. Refer to Figure 4 and Figure 3 , both ends of the column 2 are provided with retractable pull rods 8, and a handle 3 for driving the retraction and extension of the pull rods 8 is arranged on the column 2. Rotating the handle 3 can retract or extend the upper and lower pull rods 8. When closing the window, the pull rods 8 extend and enter the inner side of the first roller chute 16 to close the window body. The first window frame 4, the second window frame 5 and the column 2 are all located inside the window frame 1, as shown in Figure 1 ; when opening the window, the pull rods 8 retract inside the column 2, so that when the column 2 moves, the pull rods 8 will not interfere with the first roller chute 16, and the window body can be opened. As for how the handle 3 drives the retraction and extension of the pull rods 8, it is well known to those skilled in the art and will not be elaborated here.

[0038] Refer to Figure 6 and Figure 7 , positioning plates 6 are integrally formed on both the first shell 12 and the second shell 11. The four positioning plates 6 enclose a rectangle, and the formed protruding part in a double-square shape can achieve quick positioning during glass installation.

[0039] Refer to Figure 6 , an installation plate 13 is arranged on the side of the first shell 12 close to the window frame 1, and a rain brush 9 is arranged on the installation plate 13 (refer to Figure 11 ), and the rain brush 9 faces the inner side of the window and can achieve the sealing of the window body when closing the window.

[0040] Both the top and bottom of the inner side of the window frame 1 are fixedly installed with first roller chutes 16. Refer to Figure 8 , the cross-section of the first roller chute 16 is U-shaped, and the vertical spacing of the first roller chute 16 is d1; the U-shaped first roller chute 16 can not only provide the guiding function for the sliding of the window sash but also further play the role of preventing water leakage. If water leaks in the window sash, the leaked water will gather at the bottom end of the first roller chute 16 and be blocked by the edge of the first roller chute 16, thereby avoiding water from entering the room.

[0041] Refer to Figure 10 , the rolling unit 10 includes a housing 14 and a sphere 15. The housing 14 is fixedly connected to the first window frame 4 / second window frame 5, the housing 14 is slidably connected to the first roller chute 16, the outer diameter of the housing 14 is d1, there is a round hole at the bottom of the housing 14, the inner diameter of the round hole is d2, and the diameter of the sphere 15 is d3, and d3 is greater than d2.

[0042] Furthermore, the sphere 15 can rotate 360°, and the part of the sphere 15 exposed outside the housing 14 is in rolling connection with the first roller chute 16.

[0043] Refer to Figure 2 , rolling units 10 corresponding one by one to the first roller chute 16 are provided on both the first window frame 4 and the second window frame 5.

[0044] Both the first window frame 4 and the second window frame 5 can slide along the first roller chute 16 and can rotate relative to the window frame 1 (refer to Figure 9 ), and one side of both the first window frame 4 and the second window frame 5 is hinged to the column 2 through a hinge 7 (for the specific structure of the hinge 7, refer to Figure 5 ). After the first window frame 4 and the second window frame 5 are opened, they can be folded with the column 2 as the intermediate member and leaned against any place inside the window frame 1.

[0045] For example, after the window is opened, refer to Figure 12 , it can form a V shape and dock inside the window frame 1, refer to Figure 13 , the first window frame 4 and the second window frame 5 are arranged in a row and directly docked at the edge of the window frame 1.

[0046] With the same window opening area and in the case of an inward-opening window, the space occupied on the inner side of the house after the window is opened can be greatly reduced. For example, in the present invention, the two sash windows can be docked on one side, and utensils can be placed on the other side. When arranging the interior of the house, there is no need to consider the interference problem between the two sash windows and the utensils after they are opened.

[0047] Embodiment 2

[0048] The difference from Embodiment 1 is that:

[0049] Refer to Figures 14 to 16 , second roller chutes 17 are provided on both sides of the first roller chute 16. The rolling unit 10 can be switched between the first roller chute 16 and the second roller chute 17. A notch 20 is provided between the first roller chute 16 and the second roller chute 17. The notch 20 includes an arc segment 18 and two straight segments 19. The distance between the two straight segments 19 is d1 (the outer diameters of the housing 14 are the same), and the diameter of the arc segment 18 is d3 (the same as the diameter of the sphere 15).

[0050] Refer to Figure 16 , first push the first window frame 4 and the second window frame 5 to the edge of the window frame 1. The rolling units 10 on both sides are respectively switched into the second roller chute 17 by using the notch 20. The distance between the first window frame 4 and the second window frame 5 is widened, and the rotational freedom is restored. At this time, the column 2 can be retracted inside the window frame 1, further greatly reducing the space occupied by the sash window in the room. For example, it can avoid the situation that a child or a person of short stature bumps into the opened sash window without noticing and causing physical injuries when moving indoors.

[0051] Similarly, the second roller chute 17 can also achieve the above effect of preventing the window from leaking.

[0052] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. Any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention shall fall within the protection scope of the appended claims of the present invention.
