Description

Technical Field

[0001] The utility model relates to the technical field of door and window equipment, and more specifically to an inward opening sash structure of an aluminum profile casement window. Background Art

[0002] A type of window used in residential buildings. The window sash opens and closes horizontally, hence the name "casement window." Casement windows come in two types: sliding and top-hung. Their advantages include a large opening area, good ventilation, excellent sealing, and superior sound insulation, heat preservation, and anti-seepage properties. Inward-opening windows are easy to clean, while outward-opening ones take up little space when opened. Their disadvantages include a small window width and a limited field of view. Inward-opening casement windows, in particular, protrude into the room when opened, posing a safety hazard. Children or adults, if not paying attention, could bump into the bottom edge of the casement window, causing safety issues. Utility Model Content

[0003] One advantage of the present invention is that it provides an inward-opening structure for an aluminum casement window, in which a foldable safety cushion is installed at the lower edge of the casement window and is driven by a connecting assembly. When the window is closed, the safety cushion is in a horizontal state and can cooperate with the window frame to form a sealing structure to prevent air leakage. When the window is open, the safety cushion is in a vertical position. When a person accidentally bumps into the window, he or she will only hit the safety cushion and will not directly hit the aluminum profile, thereby protecting the person.

[0024] The first embodiment of the present utility model is as follows:

[0025] An inward-opening sash structure of an aluminum profile casement window includes a window frame 1 and a window body 4. A rotatable safety cushion 11 is provided at the bottom of the window body 4. A connecting rod assembly that is linked to the safety cushion 11 is provided inside the window 4. The connecting rod assembly includes a top rod 5 with one end passing through the window body 4. When the window 4 is closed, the top rod 5 presses against the inner side of the window frame 1 and moves into the window 4, and the safety cushion 11 is rotated to a horizontal state through the linkage of the connecting rod assembly; when the window 4 is opened, the top rod 5 leaves the inner side of the window frame 1 and moves outward of the window 4, and the safety cushion 11 is rotated to a vertical state through the linkage of the connecting rod assembly.

[0026] The end portion of the top rod 5 is provided with a top rod 5 sliding shaft, and the connecting rod assembly also includes a first rotating rod and a second rotating rod, and the middle portions of the first rotating rod and the second rotating rod are both provided with a rotating shaft; the first rotating rod includes a first frame rail 6 located at its upper portion and a first connecting rod 7 located at its lower portion, and a first slide groove is provided inside the first frame rail 6, and the top rod 5 sliding shaft is connected to the first slide groove in a relatively movable manner, and the lower end of the first connecting rod 7 is provided with a first slide shaft; the second rotating rod includes a second frame rail 8 located at its upper portion and a third frame rail 9 located at its lower portion, and the first slide shaft is connected to the second frame rail 8 in a relatively movable manner; the upper portion of the safety cushion 11 is connected to a cushion rotating rod 14, and the other end of the cushion rotating rod 14 is connected to the second connecting rod 10, and the other end of the second connecting rod 10 is provided with a second slide shaft, and the second slide shaft is connected to the third frame rail 9 in a relatively movable manner, and the angle between the cushion rotating rod 14 and the second connecting rod 10 is 130 degrees to 150 degrees; a rotating shaft is provided at the connection between the cushion rotating rod 14 and the second connecting rod 10.

[0027] The safety cushion 11 and the cushion rotating rod 14 are connected by a plurality of connecting plates 15. The connecting rod assembly and the cushion connecting rod are both located inside the window 4. The bottom of the window 4 is provided with the same number of slots as the connecting rod, and the connecting rod passes through the slots.

[0028] The entire connecting rod structure includes a top rod 5, a first rotating rod, a second rotating rod and a second connecting rod 10 connected in sequence. One end of the top rod 5 passes through the window body 4 and serves as a trigger. When the top rod 5 is pushed to the left, the first rotating rod will rotate counterclockwise with the rotating shaft as the axis, and its lower end will swing to the right. At this time, it will drive the second rotating rod to rotate clockwise, and its lower end will swing to the left. At this time, it will drive the second connecting rod 10 to rotate 90 degrees counterclockwise, causing the safety cushion 11 to also rotate 90 degrees counterclockwise. The upper half of the safety cushion 11 will be embedded in the arc-shaped groove at the bottom of the window body 4, and its lower half will be embedded in the arc surface 2 on the window frame 1, playing the role of windproof sealing to prevent air leakage.

[0029] The connecting rod assembly also includes a spring 13 located inside it and a fixed plate that supports the spring 13. The spring 13 is sleeved on the outside of the top rod 5. A reset plate is provided in the middle of the top rod 5. The spring 13 is located between the fixed plate and the reset plate. The end of the top rod 5 is moved to a position flush with the outer side of the window 4 by the thrust of the spring 13. When the window 4 is opened, under the action of the spring 13, the top rod 5 will move outward. At the same time, a torsion spring is provided at the cushion rotating rod 14 of the safety cushion 11. The spring 13 and the torsion spring jointly drive the connecting rod assembly to move, which will drive the safety cushion 11 to rotate clockwise to a downward state. The safety cushion 11 and the auxiliary point jointly play a role in preventing head collisions.

[0030] The window frame 1 includes a windshield 3, and the position of the top rod 5 corresponds to the windshield 3. When the window is closed, the outer portion of the top rod 5 will press against the windshield 3, and the windshield 3 can also play a role in releasing air leakage.

[0031] An auxiliary pad 12 is also fixedly installed at the bottom of the window 4. The lowest point of the auxiliary pad 12 is on the same horizontal plane as the lowest point of the safety cushion 11 when it is in a vertical state. On the one hand, it can help to put the head in place, and on the other hand, it can also have a sealing effect when closing the window.

[0032] It should be noted that the terms "first, second and third" in the present invention are only used for descriptive purposes and do not indicate any order. They cannot be understood as indicating or implying relative importance. These terms can be interpreted as names.

[0033] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention.
