Description

Technical Field

[0001] This utility model relates to the field of curtain technology, and in particular to a cordless combination curtain. Background Technology

[0002] The slats of a butterfly blind are made of double-layered folded fabric. The back is mesh and the front is a folded surface. Under the force of the threads, the folded surface can fold inward, forming a shape similar to butterfly wings, hence the name butterfly blind. In the folded state, the butterfly blind is mainly used to provide maximum light transmittance. When the force of the threads disappears and the folded surface unfolds, the edges of the slats can touch and overlap each other, providing privacy and light blocking.

[0003] Traditional butterfly blinds typically involve a chain-like control device for adjusting the up-and-down movement of the slats, and a diagonal pull cord for controlling the opening and closing of the butterfly slats. This design makes butterfly blinds very flexible and convenient in providing light adjustment and privacy protection, but the zipper-style pull cord poses safety hazards, such as the cord potentially getting tangled around a child's neck. Currently, pull cord blinds are gradually being phased out of the market, thus requiring a new type of combination blind to replace traditional pull-cord butterfly blinds. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a cordless combination curtain with the advantages of convenient operation and high safety.

[0005] To achieve the above and other related objectives, this utility model provides the following technical solution:

[0006] A cordless combination curtain, comprising:

[0007] A take-up tube, which is connected to a take-up drive device, is used to control the take-up tube to unwind to any blocking position and lock or release the locking force to achieve the take-up action.

[0008] A mesh curtain is attached to the top of the first side of the take-up tube;

[0009] A plurality of curtain slats are sequentially overlapped to cover the mesh curtain in the unfolded state. The upper ends of the curtain slats are fixed to the mesh curtain, and the lower ends are slidably disposed relative to the mesh curtain. A traction rope is connected to the second side of the winding tube opposite to the first side. The traction rope passes through the upper end of each curtain slat and is connected to the lower end of each curtain slat.

[0010] A light-transmitting curtain is connected to the top of the first side of the winding tube. The light-transmitting curtain is wound and unwound synchronously with the mesh curtain. When the mesh curtain is fully unwound, the light-transmitting curtain can be used to pull the winding tube to rotate by a predetermined angle so as to drive the traction rope to wind and pull the lower end of the curtain slats upward.

[0011] To achieve the above technical solution, during use, pulling down the bottom of the mesh curtain causes both the mesh curtain and the translucent drape to roll down and unroll simultaneously. Initially, all slats are unfolded, completely covering the mesh curtain, thus providing privacy and light blocking. After the mesh curtain and translucent drape are unfolded, pulling down the translucent drape a further distance causes the upper end of the traction rope, fixed to the second side of the winding tube, to reverse and wind up a section onto the winding tube. This simultaneously pulls each slat upwards, revealing the mesh curtain behind it, thereby maximizing light transmittance without affecting the light transmission of the mesh curtain. The curtain allows light to pass through; when the curtain needs to be unfolded again, gently lift the light-transmitting curtain a short distance upwards. Under the action of the winding drive device, the winding tube will rotate a certain angle, releasing the traction rope again. The lower end of the curtain can then unfold again under gravity to cover the mesh curtain. When the mesh curtain is lifted further, the winding tube will continue to wind up under the action of the winding drive device until the mesh curtain and the light-transmitting curtain are completely wound up. By using the light-transmitting curtain in conjunction with the winding drive device, the traditional pull rope structure is eliminated, thereby reducing the occurrence of safety accidents, greatly improving safety, and making the operation process more convenient and faster.

[0012] In one embodiment of this utility model, the bottom of the mesh curtain is provided with a first horizontal bar, and the bottom of the light-transmitting curtain is provided with a second horizontal bar; in the unrolled state, when the curtain is completely folded, the second horizontal bar is flush with or slightly lower than the first horizontal bar.

[0013] The above technical solution facilitates the pulling down of the mesh curtain and the light-transmitting curtain through the first and second horizontal bars, and can form a gravity balance with the winding drive device and allow for the re-unfolding of the curtain slats.

[0014] In one embodiment of the present invention, an auxiliary curtain is provided on the upper side of the topmost curtain slat, and the auxiliary curtain is fixed to the second side of the winding tube.

[0015] To achieve the above technical solution, the traction rope is fixed to the bottom surface of the auxiliary curtain, and both the traction rope and the auxiliary curtain are fixed to the second side of the winding tube. This strengthens the force between the traction rope and the winding tube, and at the same time, it can assist in top shading when the mesh curtain is fully unrolled, preventing top light leakage.

[0016] In one embodiment of the present invention, the lower end of the curtain fabric is slidably sleeved onto the mesh curtain.

[0017] The above technical solution makes the folding and unfolding process of the curtain more stable.

[0018] In one embodiment of the present invention, the winding drive device includes:

[0019] Mounting bracket, on which a mounting seat for mounting a take-up tube is rotatably connected;

[0020] At least one set of rotating units disposed within a take-up tube, the axial direction of the rotating unit being parallel to the axial direction of the take-up tube, comprising: a rotating support, a follower roller and a drive roller rotatably mounted on the rotating support, and a worm spring, wherein the worm spring is sleeved and fixed to the follower roller, and its free end is fixed to the drive roller; and,

[0021] A power conversion component is disposed between the mounting base and the rotating unit, the power conversion component being used to drive the transmission roller and the mounting base to rotate synchronously.

[0022] To achieve the above technical solution, the mounting bracket is used to assemble with the wall or curtain box. When the sheer curtain is pulled down, it drives the winding tube to rotate, simultaneously driving the mounting base and rotating unit to rotate. During the rotation, power is transmitted to the rotating unit. At this time, the power conversion component causes the transmission roller to rotate synchronously, causing the worm spring to elastically deform and gradually wind up onto the transmission roller. Because the torque of the worm spring is relatively small and can usually balance with the weight of the first and second crossbars, the sheer curtain will not automatically return to its original position after being pulled to the end. When it is necessary to wind up, the first crossbar is gently lifted upwards to break the gravitational balance, at which point the rotation... The bracket rotates in the opposite direction under the elastic force of the spiral spring, which in turn drives the winding tube to reverse and rewind the mesh curtain and light-transmitting curtain back onto the winding tube. Since the axis of the rotating unit is parallel to the axis of the winding tube, and the coiled surface of the spiral spring is consistent with the wall of the winding tube, there will be no jamming even if it comes into contact with the wall of the winding tube during operation. Therefore, the spiral spring can be set to be wider and the stroke can be set to be longer. At the same time, at least one rotating unit can be set, and one or more rotating units can be set according to the span of the mesh curtain, so as to meet the usage needs of mesh curtains of different widths.

[0023] In one embodiment of this utility model, the rotating unit is provided in multiple sets, and the multiple sets of rotating units are sequentially spliced ​​together and located inside the winding tube.

[0024] The above technical solution is achieved by splicing multiple rotating units together, which is simple to connect and can meet the needs of using mesh curtains of different widths.

[0025] In one embodiment of the present invention, the power conversion assembly includes: a rotating gear with its two ends respectively connected to the mounting base and the rotating bracket, and a transmission gear connected to the transmission roller and meshing with the rotating gear. When the winding tube rotates, the transmission gear rotates around the rotating gear.

[0026] To achieve the above technical solution, when the rotating unit rotates synchronously with the take-up tube, the transmission gear will rotate around the rotating gear, thereby driving the transmission roller to rotate and causing the take-up worm spring to undergo elastic deformation.

[0027] In one embodiment of the present invention, the mounting bracket is provided with a connecting convex shaft, the mounting seat is rotatably connected to the connecting convex shaft, and the rotating gear is fixed to the end of the connecting convex shaft.

[0028] To achieve the above technical solution, a connecting cam shaft is used to provide a rotating mounting base for the mounting seat and a mounting platform for the rotating gear.

[0029] In one embodiment of the present invention, the rotating bracket includes a first frame and a second frame that are interlocked with each other. A first support column and a second support column are provided between the first frame and the second frame to form a support. The first frame and the second frame are provided with interlocking elastic claws and buckling protrusions for locking and fixing adjacent rotating units.

[0030] To achieve the above technical solution, the first and second pillars cooperate to form a stable support structure after the first and second frames are connected, and an installation space is formed within the rotating support. The connection and fixation of the first and second frames are achieved by the interlocking of elastic claws and buckle protrusions.

[0031] In one embodiment of this utility model, the transmission roller is provided with a connecting fastener for engaging with the worm spring;

[0032] The two ends of the transmission roller are respectively provided with mutually cooperating prisms and prism holes, and the transmission rollers of adjacent rotating units are connected through the prisms and prism holes.

[0033] To achieve the above technical solution, the fasteners facilitate connection and fixation with the free end of the worm spring. By using the prism and the prism hole to cooperate, the positioning and installation of adjacent rotating units can be achieved, while the adjacent transmission rollers can rotate synchronously.

[0034] As described above, the present invention has the following beneficial effects:

[0035] This utility model provides a cordless combination curtain. By pulling down the bottom of the mesh curtain, both the mesh curtain and the light-transmitting curtain are simultaneously pulled down and rolled up. Initially, all curtains are in an unfolded state, completely covering the mesh curtain, thus providing privacy and light blocking. After the mesh curtain and the light-transmitting curtain are unfolded, when the light-transmitting curtain is pulled down a certain distance, the upper end of the traction rope is fixed to the second side of the winding tube. At this time, the traction rope will roll back a section on the winding tube, thereby simultaneously pulling each curtain upward to fold it up, revealing the mesh curtain behind it. This achieves the effect of providing maximum light transmittance, while the light transmittance of the light-transmitting curtain is not affected. This design improves the light transmission of the sheer curtain. When the curtain needs to be unfolded again, gently lift the sheer curtain a short distance upwards. The winding tube, driven by the winding mechanism, will rotate at a certain angle, releasing the traction rope. The lower end of the curtain will then unfold again under gravity to cover the sheer curtain. As the sheer curtain is lifted further, the winding tube will continue to wind it up under the winding mechanism until both the sheer curtain and the light-transmitting drape are completely rolled up. By using the light-transmitting drape in conjunction with the winding mechanism, the traditional pull rope structure is eliminated, thereby reducing the occurrence of safety accidents, greatly improving safety, and making the operation more convenient and faster.

[0046] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. It should be noted that, unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0047] Please see Figures 1 to 8 This utility model provides a cordless combination curtain, comprising: a winding tube 20, the winding tube 20 being connected to a winding drive device for controlling the winding tube 20 to unwind to any blocking position and lock or release the locking force to achieve the winding action; a mesh curtain 50 connected to the top of the first side of the winding tube 20; and a plurality of curtain slats 60 sequentially overlapped to cover the mesh curtain 50 in the unfolded state, the upper end of the curtain slats 60 being fixed to the mesh curtain 50, and the lower end being slidably disposed relative to the mesh curtain 50, and... A traction rope 61 is connected to the second side opposite to the first side of the winding tube 20. The traction rope 61 passes through the upper end of each curtain slat and is connected to the lower end of each curtain slat. A light-transmitting curtain 70 is connected to the top of the first side of the winding tube 20. The light-transmitting curtain 70 is wound up / unwound synchronously with the mesh curtain 50. When the mesh curtain 50 is in the unwound state, the light-transmitting curtain 70 can be used to pull the winding tube 20 to rotate a predetermined angle so as to drive the traction rope 61 to wind up and pull the lower end of the curtain slat to fold upward.

[0048] Specifically, the bottom of the mesh curtain 50 is provided with a first horizontal bar 51, and the bottom of the light-transmitting curtain 70 is provided with a second horizontal bar 71. In the unrolled state, when the curtain is completely folded, the second horizontal bar 71 is flush with or slightly lower than the first horizontal bar 51 to improve the aesthetics of the front view. The first horizontal bar 51 and the second horizontal bar 71 facilitate the pulling down of the mesh curtain 50 and the light-transmitting curtain 70, and can form a gravity balance with the winding drive device and allow for the operation of unfolding the curtain again.

[0049] The upper section of the curtain fabric can be fixed to the mesh curtain 50 by sewing, gluing, or Velcro fastening. An auxiliary blind curtain 62 is provided on the upper side of the topmost curtain panel. The auxiliary blind curtain 62 is fixed to the second side of the winding tube 20. The traction rope 61 can be fixed to the bottom surface of the auxiliary blind curtain 62, and both the auxiliary blind curtain 62 and the traction rope 61 are fixed to the second side of the winding tube 20, which strengthens the tension between the traction rope and the winding tube. At the same time, it can assist in top shading when the mesh curtain 50 is fully unrolled, preventing light leakage from the top. Preferably, the lower end of the curtain fabric is slidably sleeved onto the mesh curtain 50. For example, a secondary curtain is sewn at both ends of the lower end of the curtain fabric. The secondary curtain is located on the back side of the mesh curtain 50, thus cooperating with the curtain fabric to form a sleeve relationship with the mesh curtain 50, which makes the curtain fabric more stable during the folding and unfolding process. It can be understood that one end of the traction rope 61 is fixed to the winding tube 20, and when the mesh curtain 50 is unfolded, the traction rope 61 is in a fully unrolled state. At the junction of each curtain fabric and the mesh curtain 50, there is an opening for the traction rope 61 to pass through freely.

[0050] The light transmittance of the translucent blind 70 is generally greater than or equal to that of the mesh blind 50, thus not affecting the overall light transmission effect. It can usually be made of the same material as the mesh blind 50. The translucent blind 70 can be a single piece of mesh, such as... Figure 3 As shown, it can also be multiple strips, such as multiple strips of cloth or film, etc. Figure 4 As shown, as long as it is possible to pull the take-up tube 20 to rotate by a predetermined angle again, the light-transmitting curtain 70 can be set in any form. Preferably, the predetermined angle is usually 90°-180°.

[0051] The winding drive device can use existing drivers, such as existing spring roller blind drivers. In this embodiment, a self-developed winding drive device is used, which specifically includes: a mounting bracket 10, on which a mounting seat 11 for mounting the winding tube 20 is rotatably connected; at least one set of rotating units 30 disposed in the winding tube 20; and a power conversion component 40 disposed between the mounting seat 11 and the rotating units 30.

[0052] Specifically, the mounting bracket 10 is an L-shaped mounting plate with several waist-shaped slots for inserting bolts and other fasteners to fix it to the wall or curtain box. The mounting bracket 10 has a connecting convex shaft 13, which is fixed by a claw on the mounting bracket 10. The mounting seat 11 is rotatably connected to the connecting convex shaft 13 through a bearing, and a groove 12 is formed on the mounting seat 11. The winding tube 20 has a ridge 21 that engages with the groove 12. The ridge 21 engages with the groove 12 to achieve the engagement connection between the winding tube 20 and the groove 12. The ridge 21 can also be used to engage and fix the top of the mesh curtain 50 and the pull curtain 70.

[0053] The axis of the rotating unit 30 is parallel to the axis of the winding tube 20. The rotating unit 30 can be set in one or more groups as needed. When multiple rotating units 30 are set, the multiple rotating units 30 are spliced ​​together in sequence and located inside the winding tube 20. The multiple rotating units 30 are connected by splicing, which is simple and can meet the needs of using mesh curtains 50 with different widths.

[0054] The rotating unit 30 specifically includes: a rotating bracket 31, a follower roller 32 and a transmission roller 33 rotatably mounted on the rotating bracket 31, and a worm spring 34. The worm spring 34 is fixedly mounted on the follower roller 32, and its free end is fixed to the transmission roller 33. The rotating bracket 31 includes a first frame 311 and a second frame 312 that are interlocked. A first support column 313 and a second support column 314 are provided between the first frame 311 and the second frame 312 to form a support. In this embodiment, the first support column 313 and the second support column 314 are provided at opposite corners of the first frame 311 and the second frame 312. The first frame 311 and the second frame 312 are provided with interlocking elastic claws 315 and snap-fit ​​protrusions 316 for snapping and fixing adjacent rotating units 30. Preferably, claws and snap-fit ​​protrusions 316 are provided on the upper and lower sides of the first frame 311 and the second frame 312, so as to connect adjacent rotating units 30 more stably. Furthermore, a connecting fastener 35 is provided on the transmission roller 33 for engaging with the worm spring 34. The free end of the worm spring 34 may be provided with a bayonet or other structure to be adapted to the connecting fastener 35, so as to realize the connection and fixation of the two. The connecting fastener 35 facilitates the connection and fixation with the free end of the worm spring 34.

[0055] The first support column 313 and the second support column 314 cooperate to form a stable support structure after the first frame 311 and the second frame 312 are connected, and an installation space is formed in the rotating support 31. The first frame 311 and the second frame 312 are connected and fixed by the interlocking of the elastic claw 315 and the snap-fit ​​protrusion 316.

[0056] Furthermore, the two ends of the transmission roller 33 are respectively provided with mutually cooperating prisms 36 and prism holes 37. The transmission rollers 33 of adjacent rotating units 30 are connected by transmission through prisms 36 and prism holes 37. By cooperating with prisms 36 and prism holes 37, the adjacent rotating units 30 can be positioned and installed at the same time, and the adjacent transmission rollers 33 can rotate synchronously. It can be understood that in some embodiments, mutually cooperating protrusions and guide holes can also be provided between the first frame 311 and the second frame 312 of adjacent rotating units 30. By the interlocking of protrusions and guide holes, the connection between prisms 36 and prism holes 37 is made more stable for the connection of adjacent rotating units 30.

[0057] The power conversion assembly 40 is used to drive the transmission roller 33 and the mounting base 11 to rotate synchronously. The power conversion assembly 40 specifically includes: a rotating gear 41 with its two ends connected to the mounting base 11 and the rotating bracket 31 respectively, and a transmission gear 42 connected to the transmission roller 33 and meshing with the rotating gear 41. When the take-up tube rotates, the transmission gear 42 rotates around the rotating gear 41. When the rotating unit 30 rotates synchronously with the take-up tube 20, the transmission gear 42 will rotate around the rotating gear 41, thereby driving the transmission roller 33 to rotate and the take-up coil spring 34 to produce elastic deformation.

[0058] The rotating gear 41 is fixed to the end of the connecting cam 13. For example, the rotating gear 41 is provided with a shaft end, which is inserted into the end of the connecting cam 13. Corresponding locking holes are provided on the shaft end and the connecting cam 13. The two are fixed by inserting a pin or screwing in a screw in the locking hole.

[0059] Meanwhile, a connecting housing 38, which covers the power conversion component 40, is also connected to the rotating unit 30 located near the mounting base 11. The transmission gear 42 is rotatably connected to the connecting housing 38. The connecting housing 38 protects the power conversion component 40 and provides a platform for the rotational connection of the transmission gear 42. Correspondingly, a decorative housing 39 is also snap-fitted to the rotating unit 30 located away from the mounting base 11 to improve the overall aesthetics of the device.

[0060] Mounting bracket 10 is used for assembly with the wall or curtain box. When the mesh curtain 50 is pulled down, it drives the winding tube 20 to rotate, and simultaneously drives the mounting base 11 and the rotating unit 30 to rotate. During the rotation, power is transmitted to the rotating unit 30. At this time, the power conversion component 40 causes the transmission roller 33 to rotate synchronously, causing the spiral spring 34 to undergo elastic deformation and gradually wind up onto the transmission roller 33. Since the torque of the spiral spring 34 is small and can usually be balanced with the weight of the first crossbar 51 and the second crossbar 71, the mesh curtain 50 will not automatically return to its original position after being pulled down. When it needs to be wound up, the first crossbar 51 is gently lifted upward to break the gravitational balance. At this time, the rotating bracket 31 will rotate in the opposite direction under the action of the elastic force of the spiral spring 34. This causes the winding tube 20 to reverse, rewinding the mesh curtain 50 and the light-transmitting curtain 70 back onto the winding tube 20. Since the axis of the rotating unit 30 is parallel to the axis of the winding tube 20, and the coiled surface of the spiral spring 34 is consistent with the wall of the winding tube 20, even if it comes into contact with the wall of the winding tube 20 during the operation, there will be no jamming. Therefore, the spiral spring 34 can be set to be wider, and the stroke can also be set to be longer. At the same time, at least one rotating unit 30 can be set. One or more rotating units 30 can be set according to the span of the mesh curtain 50, so as to meet the usage requirements of mesh curtains 50 with different widths. In this embodiment, the winding tube 20 can be selected for various specifications such as 25, 28, 32, and 38 mm.

[0061] In use, by pulling down the bottom of the mesh curtain 50, both the mesh curtain 50 and the light-transmitting curtain 70 are simultaneously pulled down and rolled up. Initially, all curtains are in the unfolded state, completely covering the mesh curtain 50, thus providing privacy and light blocking. After the mesh curtain 50 and the light-transmitting curtain 70 are unfolded, when the light-transmitting curtain 70 is pulled down a certain distance, the upper end of the pull rope 61 is fixed to the second side of the winding tube 20. At this time, the pull rope 61 will roll back a section on the winding tube 20, thereby simultaneously pulling each curtain upwards and exposing the mesh curtain 50 behind it, thus achieving the effect of providing maximum light transmittance, while the light transmittance of the light-transmitting curtain 70 will not affect the mesh curtain. The light transmission effect of the mesh curtain 50 is 50%. When the curtain needs to be unfolded again, gently lift the mesh curtain 50 upwards a short distance. Under the action of the winding drive device, the winding tube 20 will rotate at a certain angle, and the traction rope 61 will be unwound again. The lower end of the curtain can then unfold again under the action of gravity to cover the mesh curtain 50. When the mesh curtain 50 is lifted up again, the winding tube 20 will continue to wind up under the action of the winding drive device until the mesh curtain 50 and the light-transmitting curtain 70 are completely wound up. By setting up the light-transmitting curtain 70 in conjunction with the winding drive device, the traditional pull rope structure is eliminated, thereby reducing the occurrence of safety accidents, greatly improving safety, and making the operation process more convenient and faster.

[0062] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. All equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
