[0024] This utility model embodiment provides a device to prevent a window from falling, such as... Figure 1-6 As shown, the window includes a movable window 1 and an outer frame 2. The movable window 1 slides within the outer frame 2. The outer frame 2 is the basic structure of the lift window, installed on a wall or curtain wall as the basic structure of the window sash. The outer frame 2 supports the strength of the entire window frame. Some accessories are installed on top. The movable window 1 moves up and down by a chain connecting the side-mounted accessories, which is supported by a motor lifting the lower part. The figure only shows the installation on one side; in reality, the movable window 1 has anti-fall devices on both sides.

[0025] like Figure 1 As shown, a load-bearing rod 3 is provided on the side of the movable window 1 near the outer frame 2. It mainly connects to the suspension point and the bottom support, supporting most of the weight of the movable window 1 and transmitting the power for vertical lifting. Correspondingly, a running groove for the load-bearing rod 3 is provided on the inner side of the outer frame 2. The load-bearing rod 3 slides in the running groove as the movable window 1 rises and falls. A predetermined groove is milled on the side frame to allow the load-bearing rod 3 to run without obstruction. Infrared sensors 5 are provided on both sides of the running groove of the load-bearing rod 3. Several pin motors 6 are linearly arranged in the vertical direction of the running groove of the load-bearing rod 3. A controller is also included. The infrared sensors 5 and the pin motors 6 are electrically connected to the controller. When the infrared sensor 5 detects that the descent speed of the movable window 1 exceeds a threshold, the pin motors 6 are triggered, and the horizontal pins of the pin motors 6 pop out to stop the load-bearing rod 3 from falling further. The controller can be a Panasonic SF-C13 light curtain sensor dedicated control component.

[0026] like Figure 3 As shown, infrared sensor 5 is a grating light curtain sensor, including an infrared generating end and an infrared receiving end. The infrared generating end and the infrared receiving end are respectively vertically arranged on both sides of the running groove of the load-bearing rod 3. The infrared emitting point and the infrared receiving point are aligned one-to-one. Panasonic SF2C series optically synchronized ultra-thin safety grating light curtain sensor can be selected.

[0027] like Figure 2 As shown, a guide rail 7 is provided on the outer frame 2. The guide rail 7 is connected to the side frame to control the movement trajectory of the movable window 1. Correspondingly, a roller 8 is provided on the side of the movable window 1 near the outer frame 2. The roller 8 is connected to the side of the movable window 1 through a roller connecting plate 9. The roller 8 is rotatably connected in the guide rail 7 to control the up and down trajectory of the movable window 1.

[0028] The aforementioned guide rail 7 includes a variable guide rail 7, the upper end of which is an inclined rail. Stable operation: The cooperation between the guide rail 7 and the roller 8, as well as the design of the variable guide rail 7 and the variable direction running groove, make the moving window 1 move more smoothly and stably during the lifting and lowering process, reducing the probability of malfunctions caused by friction or poor movement.

[0029] like Figure 2 As shown, the running groove of the load-bearing rod 3 is a directional running groove, and its upper end is a directional inclined running groove. The trajectory of the load-bearing rod running groove is consistent with that of the guide rail 7.

[0030] like Figure 1 As shown, a lifting point 10 is provided on the side of the movable window 1, which is used to connect with the drive mechanism of the lifting window to drive the movable window 1 to rise and fall. If the drive mechanism is a motor and a chain, then the main connecting chain and the load-bearing rod 3 serve as a transfer mechanism;

[0031] The window protection device is designed to prevent the sliding window 1 from falling when the motor of the window suddenly fails and stalls during operation, thus protecting the sliding window 1 and the outer frame 2 from damage.

[0032] Working principle: When the anti-fall device for the lifting window is in use, the protective device consists of an infrared sensor and a horizontal pin motor 6. The horizontal pin motor 6 is installed on the outer frame 2 (side frame) close to the running groove of the load-bearing shaft, at outdoor intervals of 10cm. The exit direction of the horizontal pin 61 is as follows: Figure 2 The load-bearing rod 3, facing the side frame, has a running groove. During operation, a horizontal pin 61 pops out to block the load-bearing rod 3 above the moving window 1.

[0033] The infrared transmitter rod is installed on the side frame, with the infrared transmitter and receiver points aligned one-to-one and connected to the side frame with corner brackets.

[0034] like Figure 4 He Ru Figure 6 As shown, the transmitting area is placed outdoors close to the plug motor 6, and the infrared transmitting point is higher than the plug motor 6 and the track.

[0035] The infrared receiver is placed in the shallow area of ​​the track in the indoor direction, close to the infrared signal point of the track, which is higher than the track and can just receive the infrared signal emitted by the track.

[0036] As the window moves up and down, each component passes through the infrared sensor's range. If the speed at which the window passes the sensor is abnormal, the infrared sensor sends a signal. At this point, the sliding window 1 begins to accelerate downwards, simultaneously activating the latch motor 6 (e.g., ...). Figure 6 The horizontal pin 61 of the latch motor 6 pops out to block the load-bearing rod 3 and prevent it from moving. The window 1 continues to accelerate and fall.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
