Description

Technical Field

[0001] The present application relates to the field of shutter technology, and in particular to a shutter blade, a shutter unit, a shutter sash and a shutter. Background Art

[0002] A Venetian blind is a device installed on a window that can cover or open the window. It usually includes multiple parallel and stacked blinds connected by ropes. The angle of each blind can be changed to change the gap between adjacent blinds, thereby changing the amount of light or ventilation.

[0003] Reference Figure 1 and Figure 2 , the conventional louvers 10 are mostly in two forms, one is a straight structure and the other is a curved structure. For the louvers 10 with a straight structure or a curved structure with a small curvature, when the blinds made of them are in a closed state, the pull cord 11 will abut against the surfaces of the louvers 10 that are away from each other, causing the louvers 10 to be slightly tilted, and then there will still be a certain gap between adjacent louvers 10, and light can easily pass through the blinds through these gaps. Therefore, the light-shielding performance of the blinds made of such louvers needs to be improved.

[0004] When the arrangement density of the louvers 10 is the same (and the distance between the connection point of the pull cord 11 and the adjacent louvers 10 is the same), for the louvers 10 with a curved surface structure having a larger curvature, when the venetian blinds made therefrom are in a closed state or a state close to being closed, the adjacent louvers 10 overlap each other and have a good light-shielding performance. However, when in an open state, the gap between the adjacent louvers 10 for light to pass through is small. Therefore, the light transmission performance of the venetian blind curtain made of such louvers 10 when opened needs to be improved.

[0005] In summary, a louver is needed, and a louver curtain made of such louver has good light-shielding performance when closed and good light-transmitting performance when opened. Utility Model Content

[0006] In order to ensure that the blinds have a good shading effect when closed and a good light transmitting effect when opened, the present application provides a blind blade, a blind unit, a blind sash and a blind.

[0007] On the one hand, the present application provides a louver blade adopting the following technical solution:

[0008] A louver blade includes a main body, a first bending portion and a second bending portion, wherein the first bending portion and the second bending portion are respectively arranged obliquely on the upper and lower sides of the main body; the angle between the first bending portion and the main body is an obtuse angle; the first bending portion and the second bending portion are both arranged on the lower surface of the main body; and the width of the second bending portion is smaller than the width of the first bending portion.

[0009] By adopting the above technical solution, a plurality of louvers are assembled to form a shutter, and the first bent portion is arranged to face upward and outward. When the shutter is in a closed state, the first bent portion blocks the light parallel to the main body and the light irradiated on the upper surface of the first bent portion to a certain extent, thereby reducing the light passing through the shutter from between adjacent main bodies; for a portion of light with a smaller inclination angle, after entering between adjacent main bodies, these light rays are reflected multiple times by the two adjacent main bodies, and then emitted from the side of the main body connected to the second bent portion. When emitting, the second bent portion blocks these light rays to a certain extent; in addition, because the direction of light is inclined downward in most of the time and occasions, the first bent portion arranged at an obtuse angle to the main body can block more light.

[0010] When the blinds are in an open state, only the first bent portion with a relatively wide width blocks the light at the lower surface of the blinds, and compared with blinds made of blinds with a curved structure, more light can pass through when the blinds are arranged at the same interval. Thus, the blinds made of the blinds have a good light-shielding effect when closed and a good light-transmitting effect when opened.

[0011] Optionally, the second bending portion is detachably connected to a sponge pad, and the sponge pad is used to abut against adjacent louvers.

[0012] By adopting the above technical solution, on the one hand, the sponge pad is used to form a buffer between the second bending portion and the adjacent louver, thereby reducing the damage to the louver and the noise caused by impact when closing the louver; on the other hand, with the increase of usage time, the louver may be deformed, and the sponge pad has a certain deformation ability. Therefore, when closing the louver, the sponge pad can fill the gap between adjacent louver, thereby further improving the shading performance of the louver and extending the service life of the louver and the louver.

[0013] Optionally, the first bending portion is connected to a first reinforcement bar, and the first reinforcement bar is extended along the length direction of the first bending portion; the second bending portion is connected to a second reinforcement bar, and the second reinforcement bar is extended along the length direction of the second bending portion.

[0014] By adopting the above technical solution, the first reinforcement strip and the second reinforcement strip are used to improve the structural strength of the louver, reduce the risk of bending of the louver after long-term use, and thus extend the service life of the louver.

[0015] Optionally, the first reinforcement strip is formed by curling the first bending portion, and the second reinforcement strip is formed by curling the second bending portion.

[0016] By adopting the above technical solution, the first reinforcement strip is integrally formed with the main body, and the second reinforcement strip is integrally formed with the main body, which ensures the structural strength of the louver and facilitates the production and manufacture of the louver.

[0017] On the other hand, the present application provides a shutter unit adopting the following technical solution:

[0018] A louver unit comprises a unit frame, louvers, a first control mechanism and a second control mechanism; a plurality of louvers are provided, the plurality of louvers are connected to the unit frame, the plurality of louvers are arranged at intervals along the height direction of the unit frame, and the louvers are the louvers described above; the first control mechanism is connected to the unit frame, and the first control mechanism is used to simultaneously drive the plurality of louvers to move along the height direction of the unit frame under the action of external force; the second control mechanism is connected to the unit frame, and the second control mechanism is used to simultaneously drive the plurality of louvers to rotate under the action of external force.

[0019] On the other hand, the present application provides a shutter sash adopting the following technical solution:

[0020] A shutter sash comprises a sash frame and a shutter unit, wherein the shutter unit is connected to the sash frame and the shutter unit is the shutter unit described above.

[0021] On the other hand, the present application provides a shutter adopting the following technical solution:

[0022] A shutter comprises a window frame and shutter sashes, wherein a plurality of shutter sashes are provided and all of the plurality of shutter sashes are installed in the window frame, and the shutter sashes are the shutter sashes described above.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] By arranging the first bending portion and the second bending portion on the main body, the first bending portion and the second bending portion are used to form a certain blockage between the adjacent main body parts, thereby improving the light shielding property of the blinds; the main body is arranged straight to ensure the light transmission effect when the blinds are opened;

[0025] By arranging a sponge pad at the second bending portion, damage to the louver blades and the noise caused by impact when closing the louver can be reduced;

[0026] By arranging a first reinforcement strip at the first bending portion and a second reinforcement strip at the second bending portion, the anti-bending performance of the louver is improved and the service life of the louver is extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following is combined with Figure 3-10 This application is described in further detail.

[0039] The embodiments of the present application disclose a shutter blade, a shutter unit, a shutter sash and a shutter. Example 1

[0040] This embodiment discloses a louver.

[0041] Reference Figure 3 A louver blade includes a main body 1 and a first bending portion 2, wherein the first bending portion 2 is connected to the upper side of the main body 1, the first bending portion 2 is arranged obliquely relative to the main body 1, and the first bending portion 2 is extended along the length direction of the main body 1. A second bending portion 3 is arranged on the lower side of the main body 1, the second bending portion 3 is arranged obliquely relative to the main body 1, the second bending portion 3 and the first bending portion 2 are both arranged on the lower surface of the main body 1, and the second bending portion 3 is extended along the length direction of the main body 1. The width of the second bending portion 3 is smaller than the width of the first bending portion 1.

[0042] When assembling the blinds, the first bent portion 2 is arranged upward and outward. When the blinds are in a closed state, the first bent portion 2 forms a certain shielding for the light parallel to the main body 1 and the light irradiated on the upper surface of the first bent portion 2, reducing the light passing through the blinds from between the adjacent main bodies 1; for a part of the light with a smaller inclination angle, after entering between the adjacent main bodies 1, these light rays are reflected multiple times by the two adjacent main bodies 1, and then emitted from the side of the main body 1 connected to the second bent portion 3. When emitting, the second bent portion 3 forms a certain shielding for these light rays, reducing the light passing through the blinds, thereby improving the light shielding performance of the blinds.

[0043] Reference Figure 3 and Figure 4 When the shutter is in an open state, compared with the shutter made of curved louvers, when the shutters are arranged at the same interval, since the first bent portion 2 and the second bent portion 2 are both arranged on the lower surface of the main body 3, and the width of the second bent portion 3 is smaller than the width of the first bent portion 2, and the main body 1 is arranged straight, only the first bent portion 2 blocks the light between adjacent main bodies 1, and there is still a large gap between adjacent louvers for light to pass through. Therefore, the shutter made of the louver has good light transmittance when opened and good light shielding when closed.

[0044] In this embodiment, the first bending portion 2 is integrally formed with the main body 1, and the second bending portion 3 is integrally formed with the main body 1, so as to facilitate the production of the louver. It is understandable that in other embodiments, the first bending portion 2 can also be welded or bonded to the main body 1.

[0045] Since the direction of light is inclined downward in most of the time and occasions, in this embodiment, the angle between the first bent portion 2 and the main body 1 is an obtuse angle, so that the angle between the first bent portion 2 and the light is closer to 90°, thereby blocking more light and further improving the light-shielding performance of the blinds.

[0046] It can be understood that, in this embodiment, the angle between the second bending portion 3 and the main body portion 1 is also an obtuse angle, so as to block more light passing through between adjacent main body portions 1 .

[0047] In this embodiment, the angle between the second bending portion 3 and the main body 1 is greater than the angle between the first bending portion 2 and the main body 1, so as to reduce the bending difficulty of the second bending portion 3 with a smaller width and facilitate the production of the louver.

[0048] The implementation principle of Example 1 is: by obliquely setting the first bending portion 2 and the second bending portion 3 on the upper and lower sides of the main body 1, the first bending portion 2 is used to form a certain blockage for the light parallel to the main body 1 and irradiated on the upper surface of the first bending portion 2, and the second bending portion 3 is used to form a certain reflection and blockage for the light entering between adjacent main bodies 1, thereby improving the shading performance of the blinds.

[0049] At the same time, the main body 1 is arranged straight, the first bending portion 2 and the second bending portion 3 are both arranged on the lower surface of the main body 1, and the width of the first bending portion 2 is greater than the width of the second bending portion 3, ensuring the light transmission effect when the blinds are opened. Example 2

[0050] Reference Figure 5 and Figure 6 The difference between this embodiment and the embodiment 1 is that the second bending portion 3 is provided with a sponge pad 4, which is used to abut against the adjacent louvers. With this design, on the one hand, the sponge pad 4 is used to form a buffer between the second bending portion 3 and the adjacent louvers, reducing the damage to the louvers and the noise caused by the impact when closing the louvers; on the other hand, with the increase of the use time, the louvers may be deformed, and the sponge pad 4 has a certain deformation ability. Therefore, when the louvers are closed, the sponge pad 4 can fill the gap between the adjacent louvers, thereby further improving the shading performance of the louvers and extending the service life of the louvers and the louvers.

[0051] In this embodiment, the sponge pad 4 is detachably connected to the second bending portion 3, so as to facilitate replacement and cleaning of the sponge pad 4, thereby further extending the service life of the blinds.

[0052] The specific structure of the detachable connection between the sponge pad 4 and the second bending part 3 is: the sponge pad 4 is bonded and fixed to the outer surface of the U-shaped clamping part 41, and the U-shaped clamping part 41 is used to clamp with the side of the second bending part 3 away from the main body 1. It has a simple structure and is easy to disassemble and assemble, and can improve the structural strength of the louver to a certain extent.

[0053] In other embodiments, the sponge pad 4 may also be bonded and fixed to the second bending portion 3 . Example 3

[0054] Reference Figure 7 The difference between this embodiment and the embodiment 1 is that the first bending portion 2 is connected to a first reinforcing strip 21, and the first reinforcing strip 21 is extended along the length direction of the first bending portion 2. The second bending portion 3 is connected to a second reinforcing strip 31, and the second reinforcing strip 31 is extended along the length direction of the second bending portion 3. Thus, the first reinforcing strip 21 and the second reinforcing strip 31 are used to improve the structural strength of the louver, reduce the risk of the louver bending after long-term use, and thus extend the service life of the louver.

[0055] In this embodiment, the first reinforcing strip 21 is formed by curling the first bending portion 2, and the second reinforcing strip 31 is formed by curling the second bending portion 3, so as to facilitate the production and manufacture of the louver. In other embodiments, the first reinforcing strip 21 and the second reinforcing strip 31 can also be formed by bonding or welding other rigid strips to the first bending portion 2 and the second bending portion 3, respectively. Example 4

[0056] This embodiment discloses a shutter unit.

[0057] Reference Figure 8 A louver unit includes a unit frame 5, louvers, a first control mechanism 6, and a second control mechanism 7. A plurality of louvers are provided, and the plurality of louvers are connected to the unit frame 5, and the plurality of louvers are arranged at intervals along the height direction of the unit frame 5. The first control mechanism 6 is connected to the unit frame 5, and the first control mechanism 6 is used to simultaneously drive the plurality of louvers to move along the height direction of the unit frame 5 under the action of an external force. The second control mechanism 7 is connected to the unit frame 5, and the second control mechanism 7 is used to simultaneously drive the plurality of louvers to rotate under the action of an external force.

[0058] The specific structures of the first control mechanism 6 and the second control mechanism 7 are both prior art and will not be described in detail here. Example 5
