Abstract
A curtain blind winding mechanism, applicable for use in a horizontal curtain blind that uses cords to operate horizontal roll-up and roll-down of the slats, including curtain blinds such as pleated blinds, roman blinds, cellular blinds, and so on. The present invention primarily uses a restoring drive device to act on a horizontally displaceable rolling tube, and further uses the dead weight of the slats to counteract the drive mechanism restoring force. The present invention enables single-handed operation to open up the slats by lifting a bottom edge of the slats or pulling down on the bottom edge to close the slats. Furthermore, the bottom edge of the slats can be effectively fixed at any height position.
Description
- (a) Field of the Invention
- The present invention relates to a curtain blind winding mechanism, and more particularly to a winding mechanism applicable for use in a horizontal curtain blind that uses cords to operate horizontal roll-up and roll-down of the slats, including curtain blinds such as pleated blinds, roman blinds, cellular blinds, and so on. The present invention primarily uses a restoring drive device to act on a rolling tube, which is restrained and transversely displaced. Cords respectively wind round sections of the rolling tube, and lower ends of the cords joined together lower edges of the slats, thereby enabling a user to directly hold a bottom end of the curtain blind and vertically operate the curtain blind, thereby enabling the slats to spontaneously roll up or be let down, and thus eliminating the need for other roll-up and roll-down ancillary devices.
- (b) Description of the Prior Art
- With reference to a horizontal winding curtain blind such as a pleated blind, a roman blind, a cellular blind, and so on, or similar horizontal roll-up and roll-down curtain blind, a top rail configured at a top end of the curtain blind has a drive or cord device installed therein for taking up or letting down the slats. A cord method or electromechanical drive method provides the power source for the drive mechanism to achieve the aforementioned taking up or letting down of the slats. Apart from the electromechanical method further using a rocker method, which is manually operated with two hands, thereby providing a rotating motive power, conventionally, if the cord method is used to operate taking up and letting down of the slats, because the bottom edge of the cord often becomes coiled, and easily becomes wrapped round the body of a child playing nearby, thus endangering the child, thus, the cord was removed and a cordless roll-up and roll-down device installed to provide greater safety.
- Furthermore, a winding shaft configuration was used in a winding curtain blind mechanism, two ends of which are made to roll by means of a helical spring, which rolls a cloth-form curtain blind round the circumferential surface of the rolling shaft. The user pulls directly down on a bottom edge of the curtain blind, thereby opening the slats, and, because of the resilient counteraction from the helical spring, the bottom edge must be secured by means of a binding or hook fastening method. However, during the course of taking up or letting down the slats, the user is unable to optionally fix the curtain blind at selective heights. If it is required to fix the curtain blind at a certain height, then a fixing end must additionally have a transmission mechanism providing transmission and a lock catch. However, such a configuration cannot be used in a device having cords.
- The present invention particularly provides a rolling tube for use in a horizontal curtain blind, which use cords to take up and let down the slats, including curtain blinds such as pleated blinds, roman blinds, cellular blinds, and so on, wherein the rolling tube is transversally displaced during the course of winding the slats, thereby enabling the cords to maintain in correct position. The present invention uses a restoring drive mechanism to assist an upward push from external forces, which enables the slats to be effectively rolled up. Furthermore, the dead weight of a bottom rail is used to counteract a restoring driving force of the drive mechanism, thereby enabling a bottom edge of the curtain blind to be effectively fixed at any height position. Thus, the present invention achieves objective of providing a curtain blind that can be operated without a pull cord.
- To enable a further understanding of said objectives and the technological methods of the invention herein, brief description of the drawings is provided below followed by detailed description of the preferred embodiments.

FIG. 8 shows a side cutaway view of an interior of the rolling tube further configured with a fixing member according to the present invention. -
FIG. 9 shows a schematic view depicting an electromechanical method driving the rolling tube according to the present invention. - Referring to
FIG. 1 , which shows the present invention primarily structured to comprise atop rail 1, two ends of which are configured with a leftstop end member 11 and a rightstop end member 12 respectively. Interior of thetop rail 1 provides for pivotal disposal of ahollow rolling tube 2, one end of which is driven by adrive device 3 to form a restoring reverse rotational motion. Another end of therolling tube 2 is restrained by adisplacement device 120, thereby enabling therolling tube 2 to be transversely displaced during the course of taking up or letting down slats. - The
displacement device 120 and a threadedrod 121 are coaxially configured. One end of the threadedrod 121 is joined to the rightstop end member 12, and a working end of the threadedrod 121 is rotate connected to ascrew hole 210 defined in a correspondingrotate connecting end 21 of therolling tube 2 rotate connectingend 21. Because of the rotational motion of therolling tube 2, thus, the rotate connectingend 21 is slide-shear displaced on the threadedrod 121 through a displacement distance of L2. Another end of therolling tube 2 is movably disposed on a slide-shear portion 112, and the slide-shear portion 112 is directly formed on thestop end member 11 or directly configured on a corresponding position of thetop rail 1. The slide-shear portion 112 provides for transversal displacement of therolling tube 2 through a transversal displacement distance of L1, and primarily supports therolling tube 2 to maintain displacement along an axle center line. The lengths L1 and L2 are identical. - The
rolling tube 2 is subjected to a reverse rotational driving force from thedrive device 3, and ahelical spring 31 provides a restoring motive force for therolling tube 2. One end of thehelical spring 31 is joined to an interior of therolling tube 2, and another end is joined to afixing portion 111 of the leftstop end member 11. - Referring to
FIG. 2 , which showscords 41 respectively joined to fixingportions 410 of therolling tube 2, and thecords 41 hang down therefrom and join togetherslats 40, at a bottom of which is configured a horizontal bottom rail 4, which provides for assembling the bottom slat 40 and bottom ends of thecords 41. According to requirements of the present invention, the horizontal bottom rail 4 must have a specific mass that can counteract a restoring rolling force of therolling tube 2. - The
cords 41 respectively penetrate throughholes 13 defined in a lower portion of thetop rail 1. When a user pulls down on the horizontal bottom rail 4, theslats 40 are let down, therolling tube 2 then rotates in an opposite direction. During the course of therolling tube 2 rotating, because therotate connecting end 21 of therolling tube 2 is slide-shear restrained by the threadedrod 121, thus, therolling tube 2 is transversally rightward displaced. The objective of the displacement is to enable thecords 41 to correctly position in the throughholes 13. - The horizontal bottom rail 4 can be fixed at any position through a dead weight effect of the horizontal bottom rail 4, which opposes the wind restoring force of the
rolling tube 2 produced by thedrive device 3. Furthermore, when the user raises the bottom horizontal rod 4 in an upward direction, then therolling tube 2 avoids having to bear the mass of the horizontal bottom rail 4 and caters for countering the reverse rotational force, thereby indirectly rolling up theslats 40. - Referring to
FIG. 1 , which depicts the rotational force acquired by therolling tube 2, and wherein one end of thehelical spring 31 is fixed to thefixing portion 111 of thestop end member 11, and another end is joined to the interior of therolling tube 2. Hence, even after a multiplicity of rotations of therolling tube 2, the short pitch of thehelical spring 31 enables thehelical spring 31 to maintain its elastic stress, while also effectuating an extremely uniform degree of force within an effective range between top and bottom fatigue points of thehelical spring 31. Referring toFIG. 2 , the horizontal bottom rail 4 configured at the bottom of theslats 40 can be securely positioned at any height by means of the dead weight effect of the horizontal bottom rail 4, which effectively counteracts the restoring force of therolling tube 2. - During the course of the aforementioned rolling up and letting down of the
slats 40, a transversal displacement is produced in therolling tube 2 whereby the slide-shear portion 112 supports one end of therolling tube 2 to enable maintaining displacement along the axle center line. - Referring to
FIG. 3 , therolling tube 2 assumes a long tubular form, upon which a plurality of thecords 41 can be distributed. Because the present invention uses a plurality of thecords 31, thus, the curtain blind of the present invention is relatively wide, and, correspondingly, therolling tube 2 is relatively long. Hence, astridingsupport devices 14 can be appropriately configured at positions on the girth of therolling tube 2 of thetop rail 1, which are used to support the girth of therolling tube 2 therewith. The astridingsupport device 14 can be a half-moon shaped bearing or any device able to lubricate and support therolling tube 2 and that can be configured on an exterior of therolling tube 2 to support therolling tube 2. - Referring to
FIG. 4 , which shows one end of therolling tube 2 supported by the slide-shear portion 112, which comprises a support device 5 withball bearings 50, wherein principal design of the support device 5 is that of a bearing. Abearing groove 510 is defined on the support device 5, which provides for theball bearings 50 to be movable disposed therein. The entire support device 5 is joined to thetop rail 1 by means ofbases 51. Theball bearings 50 roll on the surface of therolling tube 2, thereby substantially reducing friction, and enabling therolling tube 2 to roll more smoothly. - Referring to
FIG. 5 , which depicts the aforementionedtop rail 1 joined to thebases 51, wherein structural configuration of the support device 5 comprises theball bearings 50 movably disposed within thebearing groove 510 defined on the support device 5, and number of theball bearings 50 does not have to be large, but sufficient to be distributed in thebearing groove 510 below thetop rail 2 and provide adequate support thereof. Position confinement of theball bearings 50 is achieved by using any definedbearing groove 510. Referring toFIG. 5 , which depicts theball bearings 50 disposed in thebearing groove 510 of thebases 51 so as to at least enable a lower half of thetop rail 2 to come in contact with theball bearings 50, thereby leaving hollow a top half of thebearing groove 510 above the upper half of thetop rail 2. Moreover, theball bearings 50 must be confined to stop them from rolling into the tophalf bearing groove 510 above thetop rail 2. Design of the upperportion bearing groove 510 is depicted inFIG. 5 , which shows one of the twobases 51 positioned in reverse to that of theother base 51, thereby enabling the twobases 51 to be assembled around thetop rail 2. Hence, theball bearings 50 are unable to pass beyond the bottomhalf bearing groove 510 below thetop rail 2, and are effectively confined within the bottom portion of thebase 51. - Referring to
FIG. 6 , which shows another embodiment of the rollingtube 2, whereinexterior screw teeth 221 are further defined on a left end of the rollingtube 2, andinterior screw teeth 113 are defined on the slide-shear portion 112, which meshes with theexterior screw teeth 221. One end of thedrive device 3 is similarly fixed to thestop end member 11, and another end is joined to the interior of the rollingtube 2. A throughhole 220 is formed in a center of a right side of the rollingtube 2, which enables asmooth shaft 123 fixed to the rightstop end member 12 to be disposed therein. When the rollingtube 2 is subjected to external forces and begins to roll, theexterior screw teeth 221 mesh with theinterior screw teeth 113 of the slide-shear portion 112 and forms a shearing effect, which enables the rollingtube 2 to form a transversal displacement and rotational state. - The configuration of the rolling
tube 2 as depicted inFIG. 6 , and similar to that depicted inFIG. 1 , causes transversal displacement of the rollingtube 2 when rotating, and is subjected to a restoring reverse rotation actuated by thedrive device 3. During the course of reverse rotation, theexterior screw teeth 221 of the rollingtube 2 mesh with theinterior screw teeth 113 of the slide-shear portion 112, thereby forming a slide-shear effect that produces a rightward backward displacement in the rollingtube 2. - Referring to
FIG. 7 , the rotate connectingend 21 has a threadedrod 121 penetrating the interior of the rollingtube 2 similar to that depicted inFIG. 1 . A connecting end of thehelical spring 31 is joined to the rotate connectingend 21, and in order to prevent interference between the threadedrod 121 and thehelical spring 31, inner space of the rotate connectingend 21 is greater than that required of the threadedrod 121, and a separatingsleeve 211 is used to realize a separating effect between thehelical spring 31 and the threadedrod 121, thereby avoiding mutual interference therebetween. Size of the diameter of the separatingsleeve 211 is based purely on the requirement that there is no mutual interference between thehelical spring 31 and the threadedrod 121. If the diameter of the separatingsleeve 211 is too large, then the diameter of thehelical spring 31 will change when rotating, and result in needless interference. Thus, the diameter of the separatingsleeve 211 needs only be larger than that of the threadedrod 121. - Referring to
FIG. 8 , if the configuration ofFIG. 7 is excluded, then one end of thehelical spring 31 can be fixed to a center position of the rollingtube 2 by means of a fixingmember 23. Any method can be used to achieve fixing the fixingmember 23 to the rollingtube 2. The interior of the rollingtube 2 provides for the other end of thehelical spring 31 to be fixed thereto. A minimum consideration for the position of the fixingmember 23 is that it does not obstruct the deepest penetrable position of the threadedrod 121, thereby preventing the threadedrod 121 from interfering with straight horizontal motion of the rollingtube 2. - Referring to
FIG. 9 , which shows an end of the rollingtube 2 controlled by thedisplacement device 120, wherein an outer surface of the rollingtube 2, close to the right rotate connectingend 21 is further defined withexterior screw teeth 212. Theexterior screw teeth 212 rotate connect with aninterior screw tube 122 joined to the rightstop end member 12, thereby enabling transversal displacement of the rollingtube 2. - The rolling
tube 2 is designed to be reverse driven by a drive device, which can be anelectric motor 32 installed within the leftstop end member 11, and power is transmitted to an angular-shapedtransmission shaft 34 through adecelerator device 33. The angular-shapedtransmission shaft 34 slide shears within a corresponding angular-shapedshear hole 22 defined in an end of the rollingtube 2 opposite thereof. Theelectromechanical motor 32 provides motor-driven control, which can be further controlled by other electronic operation equipment, thereby achieving complete automation control of degree of roll-up or roll-down of theslats 40 of a horizontal winding curtain blind. Wherein the slide-shear portion 112 is similarly joined to an interior of thetop rail 1 or directly formed on the leftstop end member 11, and thedecelerator device 33 is used to produce a counterforce damping effect, which is able to effectively fix position of the bottom edge of the curtain blind at any height within an allowable weight range. - It is of course to be understood that the embodiments described herein are merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
