Description

Technical Field

[0001] The invention relates to the technical field of building decoration, and in particular to a shutter and a shutter railing. Background Art

[0002] Shutters are generally made of materials such as wood, glass and aluminum alloy.

[0003] With the advancement of technology, the opening and closing of blinds has been replaced by motor drive instead of manual drive, which is convenient, intelligent and efficient.

However, there are the following disadvantages: the rotation synchronization of the blinds is poor, resulting in poor shading and ventilation effects. At the same time, the transmission noise is loud and lubricating oil needs to be added regularly. Summary of the invention

[0035] Reference below Figures 1 to 6 The present invention provides a blind and a blind railing according to an embodiment of the present invention.

[0036] like Figures 1 to 5 As shown, the shutter 100 according to the first embodiment of the present invention can be applied to balconies, bathrooms and other places of buildings, and can play the role of sunshade and windproof and ventilation. The shutter 100 of this embodiment has the advantages of good rotation synchronization of the shutter 120, good sunshade and ventilation effects and low transmission noise.

[0037] The shutter 100 has a first direction, a second direction and a third direction, wherein the first direction is perpendicular to the second direction and the third direction respectively, and the second direction is perpendicular to the third direction. In this embodiment, according to the installation situation of the shutter 100, it is assumed that the first direction is the left-right direction, the second direction is the front-back direction, and the third direction is the up-down direction.

[0038] The structure of the shutter 100 includes a window frame 110, a shutter assembly and a driving mechanism.

[0039] The length direction of the window frame 110 extends along the first direction, and the window frame 110 has a window, and the window runs through the window frame 110 along the second direction. In the present embodiment, the window is rectangular and runs through the front and rear surfaces of the window frame 110. The structure of the window frame 110 includes two cross bars 111 and two vertical bars 113, the two cross bars 111 are arranged oppositely up and down, the length of each cross bar 111 extends along the left and right directions, the two vertical bars 113 are arranged oppositely left and right, the length of each vertical bar 113 extends along the up and down directions, and the cross bars 111 and the vertical bars 113 are vertically connected, so that the two cross bars 111 and the two vertical bars 113 can form a rectangular window. The window frame 110 can be made of aluminum alloy. The cross-sectional dimensions of the two cross bars 111 can be the same or different, and can be selected according to actual needs.

[0040] The louver assembly is arranged in the window of the window frame 110, and the louver assembly can realize the switching of the window between the open state and the closed state. The structure of the louver assembly includes a plurality of louvers 120, the length of each louver 120 extends along the third direction, each louver 120 is arranged along the first direction of the window frame 110, and the opposite ends of each louver 120 are rotatably connected to the window frame 110, the rotation axis of each louver 120 extends along the third direction, the central axis of each louver 120 coincides with its rotation axis, and each louver 120 can rotate around its own central axis relative to the window frame 110. It can be understood that the material and quantity of the louver 120 can be selected according to actual conditions, and are not specifically limited here. Each louver 120 is a rectangular plate.

[0041] The structure of the driving mechanism includes a rotating driving member 131, a transmission shaft 134, a transmission rod 135 and a rotating member.

[0042] The rotary drive member 131 is connected to one end of the transmission shaft 134, and the rotary drive member 131 is configured to drive the transmission shaft 134 to rotate around its own central axis. It is understandable that the rotary drive member 131 may include a motor and a transmission structure, and the transmission structure may be a coupling, a reducer, a gear transmission structure, etc. The rotary drive member 131 may be arranged on either side of the transmission shaft 134 along the third direction. In the present embodiment, the motor drives the transmission shaft 134 to rotate through the reducer, and the motor is located above the transmission shaft 134. The motor is a forward and reverse motor, and the output shaft of the motor can rotate clockwise or counterclockwise, so the motor can drive the transmission shaft 134 to rotate in the forward or reverse direction.

[0043] The transmission shaft 134 is disposed on one side of the shutter assembly along the first direction, and the length of the transmission shaft 134 extends along the length direction of the shutter 120. The opposite ends of the transmission shaft 134 are rotatably connected to the window frame 110. The rotation axis of the transmission shaft 134 extends along the third direction, and the transmission shaft 134 can rotate around its own central axis relative to the window frame 110. In this embodiment, the transmission shaft 134 is located on the left side of the shutter assembly, and the transmission shaft 134 is hidden in the inner cavity of the vertical rod 113 disposed in the window frame 110 to prevent the transmission shaft 134 from being affected by the outside world.

[0044] At least one end of the transmission shaft 134 and at least one end of each louver 120 are coaxially provided with a rotating member. It can be understood that in some examples, one end of the transmission shaft 134 is provided with a rotating member, the rotating member is coaxially arranged with the transmission shaft 134, and the rotating member can rotate together with the transmission shaft 134. Moreover, one end of each louver 120 is provided with a rotating member, the rotating member is coaxially arranged with the louver 120, and the rotating member can rotate together with the louver 120. At this time, the upper end of the transmission shaft 134 and the upper end of the louver 120 are both provided with a rotating member, or the lower end of the transmission shaft 134 and the lower end of the louver 120 are both provided with a rotating member. In other examples, the opposite ends of the transmission shaft 134 are provided with rotating members, the rotating members are coaxially arranged with the transmission shaft 134 and are relatively fixed. Moreover, the opposite ends of each louver 120 are provided with rotating members, the rotating members are coaxially arranged with the louver 120 and are relatively fixed.

[0045] Furthermore, each rotating member is provided with two connecting ends, and the two connecting ends are symmetrically arranged about the rotation axis of the rotating member. It is understandable that the rotating member can be made of plastic or metal. When viewed along the third direction, the rotating member is a rotationally symmetrical figure. The specific size and shape of the rotating member can be designed according to actual needs and are not specifically limited here.

[0046] In this embodiment, the rotating member is made of nylon. The rotating member includes a connecting arm and a rotating part with a circular cross-section. Two connecting arms are provided and are respectively located on opposite sides of the rotating part. The connecting arm and the rotating part are integrally formed, and each connecting arm is provided with a connecting end. For all rotating members, the distance between the two connecting ends is the same. The connecting end is a connecting hole, which is connected to the connecting hole by a bolt to realize the hinge connection between the transmission rod 135 and the rotating member.

[0047] Transmission rods 135 are provided on opposite sides of the transmission shaft 134 along the second direction, and each transmission rod 135 extends along the first direction, and each transmission rod 135 is hinged to all connection ends on the same side of the transmission shaft 134 and the rotating member. It can be understood that the transmission rod 135 can be hinged to the connection end by a hinge shaft or a bolt, and the hinge axis of the transmission rod 135 extends along the third direction. For any two rotating members, since the distance between the two connection ends on each rotating member is the same, the distance between each transmission rod 135 and the hinge of the two rotating members is the same, so these four connection ends are connected in sequence to form a parallelogram structure.

[0048] Since the lengths of the four sides of the parallelogram structure formed above are fixed, the parallelogram structure has polymorphism (or variability, instability). Therefore, when the transmission shaft 134 rotates a certain angle under the driving action of the rotating drive member 131, the transmission action of the parallelogram structure can be used to achieve synchronous rotation of all the louvers 120, that is, the rotation angle of each louver 120 is consistent.

[0049] In this embodiment, if Figures 2 to 5 As shown, the transmission shaft 134 is provided with rotating parts at both opposite ends along the third direction, each shutter 120 is provided with rotating parts at both opposite ends along the third direction, and the transmission shaft 134 is provided with transmission rods 135 at both opposite sides along its length direction.

[0050] It can be understood that the upper and lower ends of the transmission shaft 134 are provided with rotating parts, and the upper and lower ends of each louver 120 are provided with rotating parts. For the rotating parts at the opposite ends of the transmission shaft 134 and the louver 120, transmission rods 135 are provided on the upper and lower sides of the transmission shaft 134. Specifically, for the upper side or the lower side of the transmission shaft 134, the number of transmission rods 135 is two, one of which is located at the front side of the transmission shaft 134 and can be hinged to the connection end of the front side of all the rotating parts, and the other transmission rod 135 is located at the rear side of the transmission shaft 134 and can be hinged to the connection end of the rear side of all the rotating parts. With such a design, the upper and lower ends of each louver 120 can be subjected to a force, which improves the smoothness of the rotation of the louver 120.

[0051] In some embodiments, Figure 5As shown, the rotating member located on the transmission shaft 134 is set as the first rotating member, and the rotating member located on the shutter 120 is set as the second rotating member 136. Among them, the structure of the first rotating member includes an inner set 132 and an outer set 133. The inner set 132 is provided with a snap-in hole 138, and the snap-in hole 138 passes through the inner set 132 along the length direction of the transmission shaft 134. The output end of the rotary drive member 131 and the transmission shaft 134 are both fixedly connected to the snap-in hole 138. In this embodiment, viewed from the up and down direction, the shape of the snap-in hole 138 is D-shaped, and the end of the output shaft of the reducer and the end of the transmission shaft 134 are both adapted to the shape of the snap-in hole 138.

[0052] The inner sleeve 132 is provided with a first tooth portion, and the first tooth portion is provided with a plurality of first tooth portions, and the plurality of first tooth portions are evenly arranged along the outer circumference of the inner sleeve 132. The outer sleeve 133 is provided with a through hole 137, and the through hole 137 is a circular hole, and the through hole 137 penetrates the outer sleeve 133 along the length direction of the transmission shaft 134. The outer sleeve 133 is provided with a second tooth portion, and the second tooth portion is provided with a plurality of second tooth portions, and the plurality of second tooth portions are evenly arranged along the inner circumference of the through hole 137. The inner sleeve 132 is passed through the through hole 137 of the outer sleeve 133, and the first tooth portion and the second tooth portion are engaged and connected. The outer sleeve 133 is provided with two connection ends.

[0053] In this embodiment, each first tooth portion and each second tooth portion extend in the up-down direction, and the cross-sectional shape of the first tooth portion and the cross-sectional shape of the second tooth portion are both isosceles triangles. A snap-fit ​​groove is defined between any two second tooth portions, and each first tooth portion is inserted into a corresponding snap-fit ​​groove, so that the inner set 132 can be embedded in the outer set 133, so that the inner set 132 and the outer set 133 are fixed. In addition, for the first rotating member on the lower side of the transmission shaft 134, the snap-fit ​​hole 138 of the first rotating member is snap-fitted with the lower end of the transmission shaft 134.

[0054] Therefore, when the rotating driving member 131 is working, the output end of the rotating driving member 131 can drive the first rotating member located on the upper side to drive the transmission shaft 134 to rotate. At the same time, the first rotating member located on the lower side will also rotate accordingly. Moreover, with the help of the power transmission effect of the transmission rod 135, all the second rotating members 136 can drive the corresponding shutters 120 to rotate, thereby realizing the synchronous rotation of all the shutters 120 in the same direction.

[0055] In this embodiment, if Figure 3As shown, the structure of each blind 120 includes a glass clamp 122 and a glass block 121. The glass block 121 extends along the length direction of the transmission shaft 134, and the glass block 121 is a rectangular plate. Glass clamps 122 are provided at opposite ends of the glass block 121, and a connecting portion is provided at one end of the glass clamp 122 away from the glass block 121, and the connecting portion is rotatably connected to the window frame 110. The connecting portion, the glass clamp 122 and the glass block 121 are coaxially arranged. Moreover, at least one connecting portion is coaxially provided with a rotating member. In this embodiment, the connecting portion can be a nylon sleeve.

[0056] It is understandable that the shape of the connection part is not limited, as long as the glass clamp 122 and the window frame 110 can be rotatably connected. The two connection parts on each blind 120 are provided with rotating parts. The glass clamps 122 on the upper and lower sides exert a certain clamping and fixing effect on the glass block 121, so that the glass block 121 can rotate relative to the window frame 110. The setting of the glass block 121 facilitates people to enjoy the scenery outside through the glass block 121 and achieves the effect of sheltering from wind and rain. Of course, it is not ruled out that the blind 120 is made of wood or metal.

[0057] Furthermore, the length direction of the glass clamp 122 extends along the width direction of the glass block 121. In this embodiment, the length of the glass clamp 122 is perpendicular to the up-down direction. In addition, the glass clamp 122 has step portions at opposite ends, and the step portions are integrally formed with the glass clamp 122.

[0058] The blind 100 has an open state and a closed state. When the blind 100 is in the closed state, the surfaces of any two adjacent glass blocks 121 abut against each other, and the step portions of any two adjacent glass clips 122 are engaged and connected.

[0059] Specifically, Figure 3 As shown, the surface of the glass block 121 with the largest area in the up-down direction is the first surface, and the surface with the smallest area is the second surface. When each blind 120 rotates a certain angle to maximize the opening angle of the blind 100, the two second surfaces of the glass block 121 are respectively arranged to face forward and backward, and the two first surfaces are respectively arranged to face left and right, and the two step portions of the glass clamp 122 are respectively arranged to face forward and backward; when each blind 120 rotates a certain angle to close the blind 100, each blind 120 is arranged at an angle, and the step portions of two adjacent glass clamps 122 are fitted together. At the same time, the first surfaces of two adjacent glass blocks 121 are in contact with each other. Therefore, there is no gap between each blind 120, thereby improving the windproof effect of the blind 100.

[0060] It is understood that, in some examples, the shutter 120 close to the vertical rod 113 of the window frame 110 may abut against the vertical rod 113 to avoid air leakage due to a gap between the shutter 120 and the vertical rod 113. In other examples, a stopper is provided on one side of the vertical rod 113 close to the shutter 120, and the shutter 120 close to the vertical rod 113 of the window frame 110 may abut against the stopper.

[0061] In some embodiments, Figure 3 and Figure 4 As shown, the shutter 100 further includes a position detection switch 140 and a controller.

[0062] The position detection switch 140 is disposed on one side of the transmission shaft 134. Two position detection switches 140 are provided. The two position detection switches 140 are respectively used to limit the clockwise rotation angle and the counterclockwise rotation angle of the transmission shaft 134. In some examples, the transmission shaft 134 is provided with a trigger member for triggering the position detection switch 140. In other examples, the rotating member on the transmission shaft 134 is provided with a trigger member for triggering the position detection switch 140.

[0063] Moreover, the controller is electrically connected to the position detection switch 140 and the rotation driving member 131 through lines, and the controller is configured to control the rotation driving member 131 to stop running according to the detection signal of the position detection switch 140 .

[0064] It is understandable that the position detection switch 140 can be a travel switch, in which case the triggering member can be an abutment portion connected to the transmission shaft 134 or a rotating member on the transmission shaft 134, and the abutment portion can contact the travel switch to trigger the travel switch. In addition, the position detection switch 140 can also be a slot-type photoelectric switch, in which case the triggering member can be a sensor sheet connected to the transmission shaft 134 or a rotating member on the transmission shaft 134, and the sensor sheet can be placed in the sensing area of ​​the slot-type photoelectric switch to trigger the slot-type photoelectric switch.

[0065] The controller can be a control device with simple logic control function such as a 51 single chip microcomputer and a PLC controller. When the transmission shaft 134 rotates clockwise to the position under the driving action of the rotating drive member 131, the trigger member will rotate with the transmission shaft 134 and trigger one of the position detection switches 140, so that the position detection switch 140 sends the generated detection signal to the controller, so that the controller can send a stop signal to the rotating drive member 131. When the transmission shaft 134 rotates counterclockwise to the position under the driving action of the rotating drive member 131, the trigger member will rotate with the transmission shaft 134 and trigger another position detection switch 140, so that the position detection switch 140 can generate a detection signal and transmit it to the controller. At this time, the controller will control the rotating drive member 131 to stop running after receiving the detection signal. With such a design, the maximum clockwise rotation angle and the maximum counterclockwise rotation angle of the shutter 120 can be automatically controlled, so that the shutter 100 can switch back and forth between the closed state and the maximum open state.

[0066] In some examples, a shutter assembly and a drive mechanism are provided on the same frame. In other examples, such as Figure 2 As shown, two louver assemblies and two driving mechanisms are arranged on the same frame, the two louver assemblies are symmetrically arranged along the first direction, and the two driving mechanisms are also symmetrically arranged along the first direction.

[0067] In this embodiment, if Figures 1 to 5 As shown, the two cross bars 111 and the two vertical bars 113 in the window frame 110 are hollow inside, and the rotary drive member 131 is arranged in the cross bar 111 located on the upper side. In addition, the window frame 110 also includes a mounting frame 114 and a mounting plate 115, and the mounting frame 114 and the mounting plate 115 are extended in the left-right direction. There are two mounting frames 114, and the two mounting frames 114 are symmetrically arranged up and down. The mounting frame 114 located on the upper side is fixedly connected to the lower surface of the cross bar 111 located on the upper side, and the mounting frame 114 located on the lower side is fixedly connected to the upper surface of the cross bar 111 located on the lower side. For each mounting frame 114, there are two mounting plates 115, and the mounting plates 115 are arranged in the mounting frame 114 and connected to the mounting frame 114 by screws.

[0068] The transmission shaft 134 is arranged in the vertical rod 113, and the opposite ends of each louver 120 can be rotatably connected with the mounting frame 114 and the mounting plate 115 through a bearing seat or a bearing sleeve. The rotating member and the transmission rod 135 are both arranged in the mounting frame 114. It can be understood that the interior of the cross bar 111, the interior of the vertical rod 113 and the interior of the mounting frame 114 are connected, so that the rotating drive member 131, the transmission shaft 134, the transmission rod 135 and the rotating member can be assembled in the window frame 110 and generate a corresponding connection relationship. The position detection switch 140 can be arranged in the vertical rod 113 or in the mounting frame 114. In addition, the opposite ends of the two cross bars 111 are provided with end caps 112, and the end caps 112 are connected to the cross bars 111 by screws. After the end caps 112 are removed, it is convenient to maintain the rotating drive member 131.

[0069] During the use of the shutter 100 provided in the embodiment of the first aspect of the present invention, since the plurality of shutters 120 are arranged along a first direction and are rotatably arranged at the window on the window frame 110, the window opening and closing are controlled by rotating all the shutters 120, thereby realizing the sunshade, windproof function or ventilation function of the shutter 100.

[0070] Furthermore, since a rotating member is coaxially arranged on each louver 120 and a rotating member is coaxially arranged on the transmission shaft 134, when the louver 120 and the transmission shaft 134 rotate, the rotating member can rotate therewith, and each rotating member is provided with two connecting ends symmetrical about the rotation axis of the rotating member, and a transmission rod 135 extending along the first direction is correspondingly arranged for the two connecting ends on the rotating member, and the transmission rod 135 is hinged to all connecting ends located on the same side of the transmission shaft 134 along the second direction. Therefore, the transmission rods 135 located on opposite sides of the transmission shaft 134 along the second direction and the connection points of any two rotating members can be connected and together form a parallelogram structure with unchanged side lengths. Then, when the rotating driving member 131 drives the transmission shaft 134 to rotate around its own central axis, the rotating member on the transmission shaft 134 will drive the rotating member on the louver 120 to rotate through the two transmission rods 135, and the louver 120 can rotate simultaneously with the rotating member thereon.

[0071] According to the instability characteristics of the parallelogram, the angle of the parallelogram structure formed above changes. At this time, the transmission rod 135 located on one side of the transmission shaft 134 can push all the louvers 120 to rotate synchronously. At the same time, the transmission rod 135 located on the other side of the transmission shaft 134 can pull all the louvers 120 to rotate synchronously. This can improve the stability of the transmission and make the opposite sides of the louvers 120 evenly stressed. The rotation of the louvers 120 is easier and more labor-saving, which helps to reduce the performance requirements of the rotating drive member 131 and reduce the transmission noise.

[0072] Compared with the prior art, the present invention can ensure good rotation synchronization of all the shutters 120 by adopting the driving mechanism of the above structure, which is beneficial to improving the ventilation effect and the sunshade and windproof effect. At the same time, the transmission noise is small, the installation is simple, the structure is stable, and it is not easy to damage.

[0073] like Figures 1 to 6 As shown, the louver railing according to the embodiment of the second aspect of the present invention can be applied to places such as balconies and exert a good safety protection effect.

[0074] The structure of the shutter railing includes a railing frame 300 and the shutter 100 of the first embodiment.

[0075] The railing frame 300 has a first direction, a second direction and an up-down direction, and the first direction, the second direction and the up-down direction are perpendicular to each other. In this embodiment, it is assumed that the first direction is the left-right direction and the second direction is the front-back direction. The length of the railing frame 300 extends along the first direction, and the railing frame 300 has an opening that penetrates along the second direction. It is understandable that the railing frame 300 can be formed by vertically connecting a plurality of metal rods. There is at least one shutter 100, and all the shutters 100 are arranged in the opening of the railing frame 300. Therefore, the shutter 100 can be opened to allow the air between the indoor and outdoor to circulate through the opening of the railing frame 300, and the safety protection can be achieved while also playing the role of guiding wind and ventilation; and the shutter 100 can also be closed to prevent the air between the indoor and outdoor from communicating through the opening of the railing frame 300, and at the same time, the railing frame 300 plays a certain role in sunshade and windproof.

[0076] It is understandable that in some examples, the opening of the railing frame 300 is provided with one shutter 100. In other examples, the opening of the railing frame 300 is provided with two or more shutters 100, so the shutters 100 can be selected to be opened and closed according to actual needs, thereby obtaining a good use effect.

[0077] In some embodiments, Figure 6 As shown, the structure of the shutter railing also includes a fixed window sash 200. Among them, the shutter 100 is provided with one, and the shutter 100 is arranged on the upper side of the fixed window sash 200. The shutter 100 and the fixed window sash 200 are both arranged in the opening.

[0078] It is understandable that the structure of the fixed window sash 200 includes a frame and a plate, and the plate can be made of glass, metal such as stainless steel, or plastic such as acrylic. The fixed window sash 200 mainly plays a role of safety enclosure, which is helpful to prevent children or toys from falling from the lower position of the blinds 100. The blinds 100 are arranged above the fixed window sash 200, and the opening and closing state of the blinds 100 is controlled according to the actual needs of the user, so that the blind railing not only plays a safety protection effect, but also can play a certain role of sunshade and windproof as well as wind guide and ventilation.

[0079] Furthermore, the structure of the shutter railing also includes a second lifting mechanism. The shutter 100 and the fixed window sash 200 are arranged adjacent to each other along the second direction, and the output end of the second lifting mechanism is fixedly connected to the shutter 100. When the second lifting mechanism is in operation, the output end of the second lifting mechanism can drive the shutter 100 to move in the up and down direction. In this embodiment, the shutter 100 is located in front of the fixed window sash 200 and on the upper side of the fixed window sash 200.

[0080] It is understandable that the second lifting mechanism can be an electric cylinder, a hydraulic cylinder, a screw lifting device, a wire rope lifting device, a chain lifting device, etc. A guide wheel and a guide rail or a slider and a slide rail can be provided between the window frame 110 of the shutter 100 and the railing frame 300 to improve the lifting stability. When the shutter 100 moves downward to its position, it can widen the field of vision and expand the ventilation area.

[0081] In other embodiments, the structure of the shutter railing further includes a first lifting mechanism. There are two shutters 100, which are arranged in the up-down direction, and the two shutters 100 are arranged adjacent to each other in the second direction. The output end of the first lifting mechanism is fixedly connected to the shutter 100 located on the upper side, and the first lifting mechanism is configured to drive the shutter 100 located on the upper side to move up and down.

[0082] It is understandable that the structures of the first lifting mechanism and the second lifting mechanism can be consistent. In this embodiment, one of the shutters 100 is used to replace the fixed window sash 200. At this time, the shutter 100 located on the lower side can be opened and closed, thereby further expanding the ventilation area. In addition, the sizes of the shutters 100 on the upper and lower sides can be inconsistent. Specifically, after the shutters 100 are fully opened, the gaps between any two adjacent shutters 120 are different, and the gap of the shutter 100 located on the lower side is relatively small to prevent children or toys from falling through the gap.

[0083] The louver railing provided in the embodiment of the second aspect of the present invention adopts the louver 100 of the above-mentioned structure, so that the louver railing has the function of safety protection while also having the function of ventilation and sunshade and windproof. Moreover, the opening and closing noise of the louver 100 is small. At the same time, the rotation synchronization of the louver 120 is high, which can improve the sunshade, windproof and ventilation effects.
