Disclosure of Invention

This scheme provides a prevent intelligence window closing device that child dropped to when solving child and being close to the window, the problem that the window can not self-closing.

In order to achieve the aim, the scheme provides an intelligent window closing device for preventing children from falling, which comprises a frame and a boss of a bay window; the frame is fixed in a building wall; the frame is fixedly provided with first glass, and the first glass is provided with an opening; pulleys are arranged on two sides of the frame, and second glass is connected onto the pulleys in a sliding mode; the shape of the second glass is matched with the opening; a plurality of springs are uniformly distributed in the boss, one end of each spring is connected with the floor, the other end of each spring is connected with the boss, an air cushion is arranged below the boss, the lower end face of the first air cushion is in contact with the floor, and the upper end face of the first air cushion is in contact with the boss; the upper end face of the boss is made of an elastic material; the air cylinder is provided with an air inlet pipeline and an air outlet pipeline; the air inlet pipeline is provided with an air inlet one-way valve, and the air outlet pipeline is provided with an air outlet one-way valve; the air inlet pipeline and the air outlet pipeline are respectively connected with the first air cushion; the piston rod of the air cylinder supports the second glass.

The principle of the scheme is as follows: under normal conditions, the second glass is positioned below the opening of the first glass, the indoor ventilation state is kept through the opening of the first glass, when a child climbs the upper boss, the upper end surface of the boss is stressed to extrude the spring to enable the spring to retract, the spring retracts to enable the first air cushion to be stressed, the first air cushion is stressed to transfer to the floor, and the floor gives resilience force to the first air cushion to enable the first air cushion to be extruded to deform; then the air in the first air cushion is extruded out to open an air inlet one-way valve of an air inlet pipeline, then the air is conveyed into the air cylinder, a piston rod of the air cylinder moves upwards, the second glass is pushed upwards in the process of moving the piston rod upwards, the second glass just blocks the opening of the first glass, and the bay window is in a closed state at the moment; when the child continuously plays on the boss, the gravity that the boss received is unchangeable, and first air cushion continuously receives the extrusion, and the air in the cylinder keeps balanced, and second glass does not fall. When the child goes down from the boss, the second glass descends under the action of self gravity and extrudes air in the air cylinder through the piston, the air outlet one-way valve is opened at the moment, the air in the air cylinder returns to the first air cushion through the air outlet pipeline, the boss is restored to the initial state, the openings of the second glass and the first glass are staggered, the bay window is in the opened state, and indoor ventilation can be achieved to keep indoor air clean.

The beneficial effect of this scheme: the window is controlled to be closed by the ingenious utilization of the scheme, the indoor ventilation is kept, meanwhile, the child is prevented from falling from the window, and the window is very intelligent and practical.

Furthermore, the extensible length of the piston rod is equal to the length of the second glass which changes from the initial position to the position when the second glass is matched with the opening, so that even if a child with heavy weight plays at the window, the second glass cannot move upwards to the position beyond the opening, and the second glass is staggered with the opening.

Further, the first air cushion is in contact with the floor through the rubber cushion. If not set up the rubber pad and make first air cushion direct and floor contact, this process of the weight of toddler on passing the floor from first air cushion is longer than the process of force directly passing the rubber pad from first air cushion, can lead to the second glass to shift up the time long, and the time of closing the window also can prolong, consequently sets up the rubber pad between first air cushion and floor and has reduced the time that the second glass shifted up for it is more rapid to close the window.

Further, a second air cushion is arranged between the first air cushion and the rubber cushion, an elastic sheet is arranged between the first air cushion and the second air cushion, and the elastic sheet is connected with a spring; the upper end surface of the first air cushion is contacted with the boss, the lower end surface of the first air cushion is contacted with the elastic sheet, the lower end surface of the second air cushion is contacted with the rubber cushion, and a gap is formed between the second air cushion and the elastic sheet; the second air cushion is provided with a channel, the channel is hermetically connected with one end of the air inlet pipeline, which is far away from the air inlet one-way valve, an air bag is arranged at the joint of the channel and the air inlet pipeline, and the air bag is communicated with the channel; the elasticity of the second air cushion is larger than that of the first air cushion. When the adult is located the boss, the spring is extruded and takes place deformation, because the gravity of adult is heavier, the spring is extruded and takes place deformation also more serious, the first air cushion will be extruded simultaneously to the boss up end, flexure strip and second air cushion, because the elasticity of second air cushion is better than the elasticity of first air cushion, so the second air cushion can compress earlier, then the air that compresses out in the second air cushion gets into in the gasbag, make the gasbag inflation plug up the admission line of cylinder, make the unable cylinder that gets into through the admission line of gas in the first gasbag, the piston rod keeps motionless, second glass does not shift up, the window that wafts keeps the open mode. Even if the first air cushion is compressed, so that air in the first air cushion enters the air cylinder, the piston rod of the air cylinder pushes the second glass upwards, and the first air cushion only slightly deflates, so that the piston rod cannot push the second glass to a position corresponding to the opening of the first glass, and the window cannot be closed. When the adult gets off the boss, the first air cushion and the second air cushion are not squeezed, the air in the air bag returns to the second air cushion again, and the boss returns to the original state. When a child climbs the bay window, the spring is extruded by the stress of the upper end face of the boss to enable the spring to retract, the boss continues to be pressed downwards, then the first air cushion is compressed by the stress of the first air cushion and transmits the force downwards to the elastic sheet, and the second spring cannot be pressed due to insufficient weight of the child because a gap is formed between the elastic sheet and the second air cushion. Therefore, the air inlet pipeline of the cylinder cannot be blocked, and the automatic window closing function of the bay window cannot be influenced.

Further, the frame both ends are rotated and are provided with and rotate the wheel, it is equipped with the belt respectively to rotate to take turns, belt one end is connected with the brush, the belt other end links to each other with second glass, the brush is located first glass surface. The second glass moves down the in-process on, drives through the belt and rotates the wheel, then rotates the wheel and rotates and drive the brush through the belt and rise or descend, rubs the dust on surface for first glass, has reduced manual operation's work load.

Furthermore, the brush is a soft brush, so that the glass cannot be scratched in the process of wiping the first glass, and the health state of the glass is kept.

Further, the brush initial state is located first glass the top, can not influence the field of vision under the condition of the daily ventilation of windowing of bay window.

Furthermore, two corresponding arched holes are further formed in the side wall of the frame, steel balls are connected in the two arched holes in a sliding mode through springs respectively, and a protruding block is arranged at the upper end opening of the second glass and matched with the steel balls. When the window needs to be closed, the second glass can be pushed upwards to be overlapped with the opening of the first glass, then the convex block enters between the steel balls and is matched with the steel balls to fix the second glass, when the window needs to be opened, the second glass is pulled downwards to enable the convex block to be separated from between the two steel balls, and the second glass can be staggered with the opening of the first glass.

Be equipped with a plurality of springs 6 of evenly distributed in the boss 2, 6 one ends of spring are connected with the floor, and 6 other ends of spring are connected with boss 2, and the material of 2 up end of boss is elastic material, and when child or adult stood or sat on boss 2, a plurality of 6 atress of spring compressed and born child or adult's weight.

As shown in figures 4-5:

a first air cushion 7 and a second air cushion 8 are arranged in the boss 2, an elastic sheet 14 is arranged between the first air cushion 7 and the second air cushion 8, and the elastic sheet 14 is fixed on the boss 2; the upper end face of the first air cushion 7 is in contact with the boss 2, the lower end face of the first air cushion 7 is in contact with the elastic sheet 14, the lower end face of the second air cushion 8 is in contact with the floor through the rubber pad 13, and the second air cushion 8 and the elastic sheet 14 are at a certain distance. A channel 15 is arranged on the second air cushion 8, the channel 15 is connected with one end, far away from the air inlet one-way valve, of the air inlet pipeline 10, an air bag 16 is arranged at the joint of the channel 15 and the air inlet pipeline 10 in a sealing mode, and the air bag 16 is communicated with the channel 15; and the elasticity of the second air cushion 8 is greater than the elasticity of the first air cushion 7.

The device also comprises a cylinder 9, wherein an air inlet pipeline 10 and an air outlet pipeline 11 are arranged on the cylinder 9; an air inlet one-way valve is arranged on the air inlet pipeline 10, and an air outlet one-way valve is arranged on the air outlet pipeline 11; the air inlet pipeline 10 and the air outlet pipeline 11 are respectively connected with the first air cushion 7; the piston rod 12 of the cylinder 9 supports the second glass 4. The extendable length of the piston rod 12 is equal to the length of the second glass 4 which changes from the initial position to the position in which it fits the opening, so that even when a child with a heavy weight plays around the window, the second glass 4 does not move up to a position beyond the opening, so that the second glass 4 is misaligned with the opening.

When the child is on the boss 2, the spring 6 is extruded to the upper end face of the boss 2 under the stress, so that the spring 6 retracts, the boss 2 continues to be pressed downwards, then the first air cushion 7 is compressed by the stress self and transfers the force downwards to the elastic sheet 14, and because a certain distance is arranged between the elastic sheet 14 and the second air cushion 8, the weight of the child is not enough and the second air cushion 8 can not be pressed. Therefore, the air inlet pipe 10 of the air cylinder 9 can not be blocked, and the automatic window closing function of the bay window can not be influenced. Then the upper end surface of the boss 2 is forced to extrude the first air cushion 7, and the first air cushion 7 is extruded to deform; then, the air in the first air cushion 7 opens the air inlet one-way valve through the air inlet pipeline 10 of the air cylinder 9, then air is conveyed into the air cylinder 9, the piston rod 12 of the air cylinder 9 moves upwards, the piston rod 12 pushes the second glass 4 upwards in the upward movement process, the second glass 4 just blocks the opening of the first glass 3, and the bay window is in a closed state at the moment; when the child continuously plays on the boss 2, the gravity borne by the boss 2 is unchanged, the first air cushion 7 is continuously extruded, the air in the air cylinder 9 keeps balance, and the second glass 4 does not fall. When the child goes down from the boss 2, the second glass 4 descends under the self-gravity and presses the air in the air cylinder 9 through the piston, at the moment, the air outlet one-way valve is opened, the air in the air cylinder 9 returns to the first air cushion 7 through the air outlet pipeline 11, and the boss 2 is restored to the original state.

When an adult is positioned on the boss 2, the spring 6 is extruded to deform, because the weight of the adult is larger, the spring 6 is extruded to deform more seriously, and the upper end face of the boss 2 can extrude the first air cushion 7, the elastic sheet 14 and the second air cushion 8 simultaneously. Because the elasticity of the second air cushion 8 is better than that of the first air cushion 7, the second air cushion 8 is compressed first, then the air compressed in the second air cushion 8 enters the air bag 16, so that the air bag 16 is expanded to block the air inlet pipeline 10 of the air cylinder 9, the air in the first air bag 16 cannot enter the air cylinder 9 through the air inlet pipeline 10, the piston rod 12 keeps still, the second glass 4 does not move upwards, and the bay window keeps an open state. Even if the first air cushion 7 is compressed so that the air in the first air cushion 7 enters the air cylinder 9, the piston rod 12 of the air cylinder 9 pushes the second glass 4 upwards, and the first air cushion 7 is slightly deflated, so that the piston rod 12 cannot push the second glass 4 to a position corresponding to the opening of the first glass 3, and therefore the window cannot be closed.

When the adult gets off the boss 2, the first air cushion 7 and the second air cushion 8 are not pressed, the air in the air bag 16 returns to the second air cushion 8, and the boss 2 is restored to the original state.

As shown in fig. 6:

rotating wheels 17 are rotatably arranged at two ends of the frame 1, belts 18 are respectively arranged on the rotating wheels 17, one end of each belt 18 is connected with a brush 19, the other end of each belt 18 is connected with the second glass 4, and the brushes 19 are positioned on the surface of the first glass 3. In the process of moving upwards and falling down, the belt 18 drives the rotating wheel 17 to rotate, then the rotating wheel 17 rotates and drives the brush 19 to ascend or descend through the belt 18, so that dust on the surface of the first glass 3 is wiped, and the workload of manual operation is reduced. The brush 19 is a soft brush, which can not scratch the glass in the process of wiping the first glass 3, thereby keeping the health state of the glass. The brush 19 is initially positioned at the uppermost end of the first glass 3, and the visual field is not influenced under the condition that the bay window is opened for daily ventilation.

As shown in fig. 7:

the side wall of the frame 1 is also provided with two corresponding arched holes 20, the two arched holes 20 are respectively connected with steel balls 21 in a sliding way through springs 6, the upper port of the second glass 4 is provided with a convex block 22, and the convex block 22 is matched with the steel balls 21. The second glass is located the outside of first glass, when needing to close the window, can use a small amount of weight with the opening coincidence of second glass 4 and first glass 3, then push up second glass 4 from the opening part, make it coincide with the opening coincidence of first glass 3, then make lug 22 get into between the steel ball 21, cooperate with steel ball 21, fix second glass 4, when needing to open the window, can follow the opening part and pull second glass 4 down, can make lug 22 break away from between two steel balls 21, second glass 4 can stagger with the opening part of first glass 3.

The method comprises the following specific operations:

normally, the second glass 4 is located below the opening of the first glass 3, and the room is kept ventilated through the opening of the first glass 3.

When a child climbs the boss 2, the upper end face of the boss 2 is stressed to extrude the spring 6 to enable the spring 6 to retract, the boss 2 continues to be pressed downwards, then the first air cushion 7 is stressed to be compressed by self and transmits the force downwards to the elastic piece 14, and the weight of the child is not enough and the child cannot be pressed to the second air cushion 8 because a certain distance is reserved between the elastic piece 14 and the second air cushion 8. Then, air in the first air cushion 7 is extruded out, an air inlet one-way valve is opened through an air inlet pipeline 10 of the air cylinder 9, then air is conveyed into the air cylinder 9, a piston rod 12 of the air cylinder 9 moves upwards, the second glass 4 is pushed upwards in the upward movement process of the piston rod 12, the second glass 4 just blocks the opening of the first glass 3, and the bay window is in a closed state at the moment; when the child continuously plays on the boss 2, the gravity borne by the boss 2 is unchanged, the first air cushion 7 is continuously extruded, the air in the air cylinder 9 keeps balance, and the second glass 4 does not fall. When a child goes down from the boss 2, the second glass 4 descends under the action of self gravity and extrudes air in the air cylinder 9 through the piston, the air outlet one-way valve is opened at the moment, the air in the air cylinder 9 returns to the first air cushion 7 through the air outlet pipeline 11, so that the boss 2 is restored to the initial state, the openings of the second glass 4 and the first glass 3 are staggered, the bay window is in an opened state, and indoor ventilation can be achieved to keep indoor air clean. Since the extendable length of the piston rod 12 is equal to the length of the second glass 4 that changes from the initial position to the position in which it fits the opening, even when a child with a heavy weight plays around the window, the second glass 4 does not move up to a position beyond the opening, so that the second glass 4 is misaligned with the opening.

When an adult is positioned on the boss 2, the spring 6 is extruded to deform, because the weight of the adult is larger, the spring 6 is extruded to deform more seriously, and the upper end face of the boss 2 can extrude the first air cushion 7, the elastic sheet 14 and the second air cushion 8 simultaneously. Because the elasticity of the second air cushion 8 is better than that of the first air cushion 7, the second air cushion 8 is compressed first, then the air compressed in the second air cushion 8 enters the air bag 16, so that the air bag 16 is expanded to block the air inlet pipeline 10 of the air cylinder 9, the air in the first air bag 16 cannot enter the air cylinder 9 through the air inlet pipeline 10, the piston rod 12 keeps still, the second glass 4 does not move upwards, and the bay window keeps an open state. Even if the first air cushion 7 is compressed so that the air in the first air cushion 7 enters the air cylinder 9, the piston rod 12 of the air cylinder 9 pushes the second glass 4 upwards, and the first air cushion 7 is slightly deflated, so that the piston rod 12 cannot push the second glass 4 to a position corresponding to the opening of the first glass 3, and therefore the window cannot be closed. When the adult gets off the boss 2, the first air cushion 7 and the second air cushion 8 are not pressed, the air in the air bag 16 returns to the second air cushion 8, and the boss 2 is restored to the original state.

When the window needs to be closed for a long time, a small amount of weight can be used for enabling the second glass 4 to coincide with the opening of the first glass 3, then the second glass 4 is pushed upwards from the opening to coincide with the opening of the first glass 3, then the bump 22 enters the space between the steel balls 21 and is matched with the steel balls 21, the second glass 4 is fixed, when the window needs to be opened, the second glass 4 can be pulled downwards from the opening, the bump 22 can be separated from the space between the two steel balls 21, and the second glass 4 can be staggered with the opening of the first glass 3.

In the process of moving upwards and falling down, the belt 18 drives the rotating wheel 17 to rotate, then the rotating wheel 17 rotates and drives the brush 19 to ascend or descend through the belt 18, so that dust on the surface of the first glass 3 is wiped, and the workload of manual operation is reduced. The brush 19 is a soft brush, which can not scratch the glass in the process of wiping the first glass 3, thereby keeping the health state of the glass. The brush 19 is initially positioned at the uppermost end of the first glass 3, and the visual field is not influenced under the condition that the bay window is opened for daily ventilation.
