Description

Technical Field

[0001] The utility model relates to the technical field of shutter doors and windows, in particular to a self-protection shutter structure, a shutter movable door and window and a door and window structure. Background Art

[0002] With the continuous progress of society, people's pursuit of quality of life is also continuously improving. In this context, privacy protection and convenience of life have become the focus of people's attention. Due to their unique design, shutter doors and shutters can not only achieve privacy protection, but also provide convenient opening and closing operations to a certain extent, while also being beautiful, which makes them increasingly popular in various occasions, whether it is family homes, business hotels, or outdoor facilities.

[0003] However, the existing louver structure design has some limitations. Most products use rubber blocks as damping materials when the blades flip. Although this design is simple, its damping effect is difficult to control accurately. In severe weather conditions such as strong winds, the instability of the rubber block damping may cause the louver structure to be unable to automatically open at the preset wind force to protect the blades from damage. This situation not only increases the difficulty of maintenance, but also increases maintenance costs.

[0004] In addition, traditional shutter doors or blinds mostly use roller sliding mechanisms, and the blades are moved by the slide rails set at the bottom. Although this design is easy to operate, its disadvantage is that the slide rails are easily affected by external factors, such as being blocked by debris or damaged by being stepped on, which may cause the shutters to move poorly or even get stuck, affecting the user experience.

[0009] When the acting force generated by the wind pressure on the blade in the closed position exceeds the bearing capacity of the blade, since the louver shaft is eccentrically fixed at the end of the blade, the acting forces on both sides of the louver shaft on the blade are different. After the torque of the acting force exceeds the set value of the rotary damper, the blade is driven to rotate from the closed position to the open position, avoiding damage to the blade.

[0010] As a more preferred way, the fixed seat includes a fixed cavity, the rotary damper and the rotating sleeve are arranged in the fixed cavity.

The main shaft 132a of the rotary damper 132 and the other end of the louver shaft 12 are respectively arranged in the damper mounting groove 133b and the louver shaft mounting groove 133a. Overcoming the resistance of the rotary damper 132, the louver shaft 12 rotates, driving the blade 11 to switch between the vertical closed position and the horizontal open position;

[0073] When the acting force generated by the wind pressure on the blade 11 in the closed position exceeds the bearing capacity of the blade 11, since the louver shaft 12 is eccentrically fixed to the end of the blade 11, the acting forces on both sides of the blade 11 with respect to the louver shaft 12 are different. After the torque of the acting force exceeds the set value of the rotary damper 132, it drives the blade 11 to rotate from the closed position to the open position, avoiding damage to the blade 11.

[0074] In order to better introduce the self - protecting louver structure 1 of the present invention, the following specific application is now combined for illustration: When the self - protecting louver structure 1 of the present invention is in use, by switching the blade 11 between the vertical closed position and the horizontal open position, the blocking and release of light and wind are realized; More usefully, when the acting force generated by the wind pressure on the blade 11 in the closed position exceeds the bearing capacity of the blade 11, since the louver shaft 12 is eccentrically fixed to the end of the blade 11, the acting forces on both sides of the blade 11 with respect to the louver shaft 12 are different. After the torque of the acting force exceeds the set value of the rotary damper 132, it drives the blade 11 to rotate from the closed position to the open position, avoiding damage to the blade 11.

[0075] In this embodiment, as Figure 1 shown, the rotating assembly 13 includes two, which are respectively arranged at both ends of the blade 11. Particularly, for cost - saving considerations, only one can also be set.

[0076] In this embodiment, as Figure 1 and Figure 2 shown, a rotating hole 131a is opened in the fixed cavity and a damper fixing hole 131b is arranged at the bottom of the rotating hole 131a.

[0077] In this embodiment, as Figure 1 and Figure 2 shown, the rotating sleeve 133 is arranged in the rotating hole 131a.

[0078] In this embodiment, as Figure 1 and Figure 2 shown, the housing 132b of the rotary damper 132 is fixed in the damper fixing hole 131b, and the main shaft 132a of the rotary damper 132 extends into the rotating hole 131a and is fixed in the damper installation groove 133b.

[0079] In this embodiment, as Figure 1 and Figure 2 shown, mounting seats 111 are arranged at both ends of the blade 11, mounting holes 111a are formed in the mounting seats 111, and one end of the louver shaft 12 is fixed in the mounting hole 111a; in this embodiment, the blade 11 is a hollow structure with both ends communicating with the outside, and the mounting seats 111 block both ends of the blade 11 respectively.

[0080] To solve the above problems, as Figure 3 , Figure 4 and Figure 5 shown, the present utility model further provides a louvered movable door and window, including:

[0081] A fixed frame 2;

[0082] A plurality of the above self-protecting louver structures 1, a plurality of the blades 11 are arranged side by side and filled in the fixed frame 2, and when the blades 11 are in the closed position, adjacent blades 11 overlap each other, and the rotating components 13 at both ends of the blades 11 are fixed in the fixed frame 2.

[0083] To better introduce the louvered movable door and window of the present utility model, the following specific application is now combined for illustration: The louvered movable door and window of the present utility model includes the above self-protecting louver structure 1. First, the closing and opening of the louvered movable door and window can be realized by switching a plurality of blades 11 between the closed position and the open position. Secondly, a plurality of blades 11 in strong wind weather can automatically switch from the closed position to the open position, avoiding the damage of the louvered movable door and window caused by strong wind.

[0084] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the fixed frame 2 is formed by enclosing an upper fixed beam 21, a lower fixed beam 22, a middle fixed beam 23, and two side fixed beams 24. The rotating components 13 at both ends of the blade 11 are fixed to the side fixed beams 24. The rotating component 13 further includes a T-shaped sleeve 134. The T-shaped sleeve 134 includes an extending portion 134a and a protruding portion 134b. The extending portion 134a is a hollow tubular structure. The protruding portion 134b is integrally formed on the outer edge of one end of the extending portion. In this embodiment, a through hole 241 is provided at the corresponding position of the side fixed beam 24. The louver shaft 12 passes through the extending portion 134a of the T-shaped sleeve 134 and the through hole 241 and is fixed to the rotating sleeve 133. The other end of the extending portion also passes through the through hole 241 and is disposed in the rotating hole 131a.

[0085] In this embodiment, as Figure 3 , Figure 4 and Figure 5 shown, a stop piece for limiting the blade 11 in the closed position is provided at the lower edges of the upper fixed beam 21 and the middle fixed beam 23. When the first blade 11 on the lower side of the upper fixed beam 21 and the middle fixed beam 23 is flipped to the closed position, the upper edge of the blade 11 abuts against the stop piece and cannot be further flipped. At the same time, in the closed position, the upper edge of the blade 11 on the lower side will overlap with the lower edge of its adjacent upper blade 11, and the lower edge of the upper blade 11 limits the lower blade 11 to prevent the lower blade 11 from further flipping, thereby ensuring the stability of each blade 11 in the closed position.

[0086] In this embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the louver sliding door and window further includes a linkage rod 3. A plurality of linkage ears corresponding to the blades 11 are provided on the linkage rod 3, and the plurality of linkage ears are respectively hinged to the corresponding blades 11.

[0087] In this embodiment, as Figure 3 , Figure 4 and Figure 5 shown, the linkage ears are hinged to the lower sides of the corresponding blades 11.

[0088] To solve the above problems, as Figure 6 shown, the present utility model further provides a door and window structure, including:

[0089] The above-mentioned louver sliding door and window;

[0090] Install the frame 4, which is enclosed by an upper mounting beam 41, a lower mounting beam 42 and two side mounting beams 43. The upper mounting beam 41 is provided with an upper sliding rail, and the upper side of the fixed frame 2 of the louver movable door and window is slidably arranged on the upper sliding rail. Pushing the fixed frame 2 along the upper sliding rail drives the louver movable door and window to move within the frame 4.

[0091] To better introduce the door and window structure of the present invention, the following specific application is now combined for illustration: The door and window structure of the present invention includes the above-mentioned louver movable door and window. While having the above-mentioned advantages, since the upper side of the fixed frame 2 of the louver movable door and window is slidably arranged on the upper sliding rail, compared with the lower sliding rail, the probability of being blocked by sundries and damaged by being stepped on is very low. Therefore, it can reliably ensure the smooth movement of the louver door and window for a long time. It can be seen that the self-protecting louver structure, the louver movable door and window and the door and window structure of the present invention protect the safety of the door and window in strong wind weather and the smooth movement for a long time through the louver structure that can automatically open under the preset wind pressure and the upward-sliding louver door and window, and solve the problems in the prior art that the louver structure is difficult to automatically open under the preset wind force and the lower sliding rail is easily blocked and damaged, resulting in poor movement.

[0092] In this embodiment, as Figure 3 shown, the fixed frame 2 further includes a hanging wheel 211 arranged in the upper sliding rail. The hanging wheel 211 is slidably arranged in the upper sliding rail. The upper side of the fixed frame 2 is connected to the hanging wheel 211. When the hanging wheel 211 slides in the upper sliding rail, it drives the fixed frame 2 to move. Further, in this embodiment, two hanging wheels 211 are provided, which are respectively fixed to the left and right sides of the upper fixed beam 21.

[0093] In this embodiment, as Figure 3 shown, a guiding rail is arranged in the lower mounting beam 42. A guiding wheel 221 adapted to the guiding rail is fixed to the lower side of the fixed frame 2. The guiding wheel 221 is arranged in the guiding rail. Pushing the fixed frame 2 along the upper sliding rail drives the louver movable door and window to move. The guiding wheel 221 slides along the guiding rail, and at the same time, the guiding rail limits the guiding wheel 221. Further, in this embodiment, two lower guiding wheels 221 are also included. The two lower guiding wheels 221 are respectively fixed to the left and right sides of the lower fixed beam 22 and are both slidably arranged in the guiding rail.

[0094] In summary, the self-protecting louver structure, the louver movable door and window and the door and window structure of the present invention have the following advantages:

[0095] 1. Self - protection function: The eccentric fixed design of the louver shaft 12 enables the blades 11 to automatically rotate from the closed position to the open position when the wind pressure exceeds the bearing capacity, avoiding damage.

[0096] 2. Compact structure: The rotating assembly 13 is integrated within the fixed seat 131, including a rotary damper 132 and a rotating sleeve 133, simplifying the structure and reducing the space occupied.

[0097] 3. Easy operation: Through the operation of the rotating assembly 13, the blades 11 can be easily switched between the closed and open positions.

[0098] 4. Wind adaptability: The blades 11 are designed to automatically adjust their states according to the wind force, adapting to different environmental conditions.

[0099] 5. Easy installation: The fixing methods of the mounting seats 111 at both ends of the blades 11 and the louver shaft 12 simplify the installation process.

[0100] 6. Integration of louver movable doors and windows: Multiple self - protecting louver structures 1 are arranged side by side and filled within the fixed frame 2, realizing the overall movable door and window function.

[0101] 7. Design of the linkage rod 3: Through the design of the linkage rod 3 and the linkage ear, the synchronous movement of the blades 11 is realized.

[0102] 8. Strength of the fixed frame 2: The fixed frame 2 enclosed by multiple fixed beams provides sufficient strength and stability.

[0103] 9. Stop piece limit: The stop piece design of the upper fixed beam 21 and the middle fixed beam 23 ensures the stability of the blades 11 in the closed position.

[0104] 10. Design of the upper slide rail: The louver movable doors and windows adopt the upper slide rail design, reducing the probability of debris blockage and damage and ensuring smooth movement.

[0105] 11. Hanging wheels 211 and guiding wheels 221: The setting of the hanging wheels 211 and guiding wheels 221 improves the smoothness and guiding property of the door and window movement.

[0106] 12. Guide rail limit: The guide rail limits the guiding wheels 221 to ensure the stability and safety of the door and window movement.

[0107] The self-protecting louver structure 1 of this patent, through its innovative design, provides a solution that can automatically protect the blades 11 from damage under the action of wind. The design of the eccentrically fixed louver shaft 12 and the rotating assembly 13 enables the blades 11 to automatically switch states when the wind pressure exceeds the set value, effectively preventing damage. At the same time, this structure is compact, easy to operate, and easy to install. The design of the louver movable doors and windows further expands this concept, realizing the synchronous movement of multiple blades 11 through the fixed frame 2 and the linkage rod 3, enhancing the overall stability and adaptability. The use of the upper slide rail reduces the risk of blockage and damage during the movement of the doors and windows, and improves the service life. Overall, the self-protecting louver structure 1 and the related door and window structure design of this patent, through its self-protecting function and the upper slide rail design, solve the safety problems of the louver structure in strong wind weather and the problems of easy blockage and damage of the slide rail in the prior art, providing a safe, reliable, and easy-to-maintain door and window solution.
