Description

Technical Field

[0001] This utility model relates to a quick-install, positioning, and limiting wind brace for windows that requires no drilling, specifically a quick-install, positioning, and limiting wind brace for windows that restricts the opening angle of windows. Background Technology

[0002] During window installation and use, in order to adjust the air intake volume and direction, people often like to open the windows halfway or one-third open depending on the weather conditions to allow indoor air to circulate. However, the limiters on the market currently use fixed multi-angle settings for limiting, which lacks flexibility when limiting. For example, when it is drizzling and you still want to open the window a crack to allow indoor air to circulate, these fixed-angle limiters cannot meet the needs. Utility Model Content

[0003] The purpose of this utility model is to provide a quick-install, positioning, and limiting wind brace for windows that does not require drilling. It adopts a flexible installation method for the window sill lock, allowing users to adjust the opening angle of the window according to their own needs.

[0004] The technical solution of this utility model is based on the forearm, rear arm, window sill locker, and window frame locker. The feature is that the rear end of the forearm and the front end of the rear arm are stacked and hinged. The middle of the rear end of the forearm is bent downward and has a hook. The rear end of the rear arm is provided with a locking hole. The left and right sides of the rear arm are provided with slots corresponding to the hooks. When the forearm swings clockwise or counterclockwise, the hooks can slide into or out of the slots. Two raised semi-circular limiting balls are arranged horizontally at intervals on the bottom surface of the forearm in front of the hinge and on the top surface of the rear arm behind the hinge. The distance between the limiting balls in the front and rear directions and the central axis of the hinge of the forearm and rear arm is equal.

[0005] The window frame lock of this utility model is hinged to the top surface of the front end of the forearm in the middle. The top left and right ends of the window frame lock are equipped with self-rotating locking plates by hexagonal screws. The bottom left and right ends of the window sill lock are equipped with self-rotating locking plates. The middle of the window sill lock is provided with a downward protruding and self-rotating locking post. The top of the locking post is provided with a hexagonal screw hole. The shape of the locking post is the same as the locking hole at the rear end of the rear arm. After the locking post is inserted into the locking hole, it can rotate itself to lock the rear arm on the window frame lock.

[0006] The working principle of this utility model is that the window frame locker connects and installs the limiter inside the bottom profile of the window frame, and then the window sill locker is installed on the profile of the window sill. When the window is opened, the front arm swings, and the hook of the front arm slides into the latch of the rear arm, locking the maximum opening angle of the window. During the swing of the front arm, the limit ball at the bottom of the front arm and the limit ball at the top of the rear arm will meet. Since the front arm and the rear arm are metal strips with elasticity, the limit ball at the bottom of the front arm will slide past the limit ball at the top of the rear arm, so that the limit balls of the front arm and the rear arm enter an interleaved limit state, so that the window will not close automatically when blown by a small wind. The window can only be closed when force is applied. When the user wants to fine-tune the opening angle of the window, he only needs to use a hex screwdriver to rotate the locking pin so that the locking hole of the rear arm slides out of the locking pin to separate the window lock and achieve unlimited window opening. Alternatively, rotate the locking plate on the window sill locker to adjust the window sill locker to a suitable position on the profile, re-lock it through the locking plate, and then slide the locking hole into the locking pin to adjust the opening angle of the window, so that the window can be adjusted to any opening angle.

[0007] The advantages of this invention are its simple structure, low manufacturing cost, flexible and quick adjustment, and the ability to limit the opening angle of the window. Attached Figure Description

[0013] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, this utility model is based on the forearm 1, rear arm 2, window sill locker 4, and window frame locker 5. The feature is that the rear end of the forearm 1 and the front end of the rear arm 2 are stacked and hinged, and there is a gap between the stacked forearm 1 and rear arm 2 that is equal in height to the limiting ball 7. The middle of the rear end of the forearm 1 is bent downward and has a hook. The rear end of the rear arm 2 is provided with a locking hole. The left and right sides of the rear arm 2 are provided with slots corresponding to the hooks. When the forearm 1 swings clockwise or counterclockwise, the hook can slide into or out of the slots. Two raised semi-circular limiting balls 7 are arranged horizontally at intervals on the bottom surface of the forearm in front of the hinge and on the top surface of the rear arm behind the hinge at the hinge point of the forearm 1 and the rear arm 2. Moreover, the distance between the limiting balls in the front and rear directions and the central axis of the hinge point of the forearm and the rear arm is equal. The window frame lock 5 is hinged to the top surface of the front end of the forearm 1 at the middle. The top left and right ends of the window frame lock 5 are equipped with self-rotating locking plates 6. The bottom left and right ends of the window sill lock 4 are equipped with self-rotating locking plates 6. The middle of the window sill lock 4 is provided with a downward protruding and self-rotating locking pin 3. The shape of the locking pin 3 is the same as the shape of the locking hole at the rear end of the rear arm. After the locking pin 3 is inserted into the locking hole, it can rotate itself to lock the rear arm 2 on the window frame lock 5.
