A curtain reel structure includes a reel, which is composed of a bottom shell, a force wheel, a driving gear plate, two rotating seats, two reels and a top shell. The bottom shell is a long plate-shaped shell, and the force wheel, the driving gear plate, the rotating seat and the reel are assembled and installed in combination with the top seat. The force wheel cooperates with a plurality of planetary gears to gear with the driving gear plate. The driving gear is then connected to the winding wheel and the rotating seat, and the high speed reduction ratio of the planetary gear is used to effectively reduce the weight of the vortex spring, which helps to reduce the cost of using the vortex spring. The winding device also uses a long plate design of the bottom shell to allow the force wheel, rotating seat and winding wheel to be assembled on the same base plane, thereby simplifying the structural design of the winding device.

Description

Curtain roller structure

This work is about a curtain structure, especially a curtain roller structure without a pull rope.

Curtains are a tool used in indoor environments to temporarily block light from windows, avoid excessive sunlight and ensure a certain degree of privacy. Generally speaking, the height of curtains is often controlled by pulling a rope, but because the rope may cause accidents such as entanglement or suffocation, curtains have gradually been improved to a rope-free form, and a retracting mechanism is used to assist the rope through the curtain sheet to pull and release. However, frequent use of the retracting mechanism to adjust the curtain to a specified position will repeatedly retract and release the spring in it to The rotation of the gear and the limitation of the position of the curtain must eventually be overcome by the use of springs. When the spring is excessively, retracted and released for a long time and repeatedly, it is easy to fatigue and damage, which eventually leads to the instability of the retracting mechanism. Therefore, it is necessary to rely on the size of the spring itself, such as thickness and width, to achieve the effect of increasing the elasticity, and cooperate with the limit device to provide friction for a long time to resist the movement of the pull rope to assist the spring to avoid fatigue due to excessive use of elasticity, thereby reducing the elasticity requirements of the spring and reducing the volume and cost of the spring.

In addition, the U.S. Patent Publication No. US11459819B2 discloses a blind structure, a frame; two winders are inserted and supported by the frame, wherein each winder is formed with its own gear, wherein the gears of the winders are engaged with each other so that the winders can rotate in different directions. Two spring shafts are inserted and supported on the frame, wherein each spring shaft is formed with its own gear, wherein the gears of the spring shafts are engaged with each other so that the spring shafts can rotate in different directions. The spring sheet includes two sections, each of which is wound around a spring winding shaft, and when the spring winding shaft rotates, one section of the spring sheet becomes longer and the other section of the spring sheet becomes shorter; the reducer is located outside the frame so that the reducer can be replaced by another reducer, wherein the reducer includes a guide wheel connected to one of the spring winding shafts and a driven wheel connected to one of the reel shafts, wherein the guide wheel is operably connected to the driven wheel, wherein the diameter of the guide wheel is smaller than the diameter of the driven wheel, so that the reel rotates slower than the spring reel, and wherein no spring reel is engaged with any reel without engaging the reducer.

However, the above-mentioned known spring winding shaft and the winding shaft do not have a direct transmission relationship. The energy storage wheel must indirectly drive the winding shaft to rotate through the guide wheel and the driven wheel of the reduction wheel. Therefore, the known reduction wheel cannot increase the torque of the spring winding shaft, so the spring sheet cannot effectively reduce the length and volume of use. Under the current situation where the price of spring sheets is gradually increasing, it is difficult to effectively reduce the structural cost. At the same time, it also causes the transmission mechanism to be larger and has a design problem of assembly space. It is necessary to improve it.

In view of this, the creator has been engaged in the manufacturing, development and design of related products for many years. Aiming at the above goals, after careful design and careful evaluation, he finally obtained this creation which is truly practical.

First, please refer to FIGS. 1 to 5 to see a curtain reel structure, which includes a reel 10. The reel 10 is composed of a bottom shell 11, a force wheel 12, a driven gear plate 13, two rotating seats 14, two reels 15 and a top shell 16.

A first rotating shaft 115 and a second rotating shaft 116 are respectively provided on both sides of the planetary gear seat 111 of the bottom shell 11. A rope outlet 117 is formed at both ends of the bottom shell 11. The rope outlet 117 is provided with at least one axle 118 and a guide rope wheel 119. To further explain, the rope outlet 117 is provided with three axles 118. The axles 118 are A guide rope wheel 119 is provided, and a hollow sleeve hole 122 with an inner ring tooth 121 is formed in the center of the force wheel 12. The force wheel 12 is sleeved on the outside of the planetary gear seat 111 with the hollow sleeve hole 122, and the inner ring tooth 121 and the planetary gear 114 are geared together. A driving gear 131 is protruded at the center of one side of the driving gear plate 13. The driving gear 131 is passed through the through hole of the upper cover 17. 171 is placed in the meshing space 113 of the planetary gear seat 111 to mesh with the planetary gear 114, and the driving gear 13 is rotatably stacked above the force-bearing wheel 12. The upper ends of the two rotating seats 14 are each provided with a linked gear 141, and the outer diameters of the two rotating seats 14 are each wound with a spiral spring 142. The two rotating seats 14 are respectively assembled on the two first rotating shafts 115, and the linked gear 141 and the driving gear 13 are geared to each other, and one end of the vortex spring 142 is fixed to the two sides of the force wheel 12 respectively. The two winding wheels 15 each have at least one winding space 151 to wind a rope body 152 respectively, and a driving gear 153 is provided at the upper end of the two winding wheels 15. The two winding wheels 15 are assembled on the two second rotating shafts 116, and the driving gear 153 is connected to the rotating seat 14. The linkage gear 141 is geared, and the other end of the rope body 152 is respectively supported and passed through the guide rope wheel 119, and then pulled out from the rope outlet parts 117 at both ends of the bottom shell 11. The top shell 16 is provided with a plurality of buckle holes 160 around it, and a central shaft 161 is provided at the center of the bottom surface of the top shell 16, and a first shaft 162 and a second shaft 163 are provided on both sides of the central shaft 161 in sequence to connect with the bottom shell. The first and second rotating shafts 115 and 116 of the bottom shell 11 correspond to each other, and the driving gear 13, the rotating seat 14 and the winding wheel 15 are further axially positioned, and the force-bearing wheel 12, the two rotating seats 14 and the two winding wheels 15 are restricted between the bottom shell 11 and the top shell 16. Finally, the buckle hole 160 is buckled and fixed with the buckle vertical plate 110 of the bottom shell 11 to complete the structural assembly of the winding device 10.

The implementation of the structure is shown in Figures 6 to 9. The reel 10 is centrally mounted in an upper rail 21 of a window curtain 20, and a damper 211 is provided on both sides of the reel 10 inside the upper rail 21. A curtain body 22 that can be unfolded and retracted upward and downward is provided below the upper rail 21, and a counterweight lower rail 23 is provided at the bottom of the curtain body 22. The second rope body 152 is pulled out from the second rope outlet portion 117, passes through the damper 211 and then passes through the upper rail 21 downward. The second rope body 152 then passes through the curtain body 22 and is connected to the counterweight lower rail 23. When the curtain body 22 is pulled down and unfolded, the second rope body 152 is pulled out from the rope space 151 of the second rope wheel 15, and drives the second rope wheel 15 to rotate. When the second winding wheel 15 is engaged with the driving gear 153 at the upper end, the connecting gear 141 of the second rotating seat 14 is driven to rotate, so that the second rotating seat 14 rotates to relax the winding spring 142, and at the same time, the two connecting gears 141 are engaged to connect the driving gear 13, and then the driving gear 131 is engaged to connect the planetary gear 114 and drive the force wheel 12 The two vortex springs 142 are rotated and retracted, and the rotational torque of the force wheel 12 is increased through the planetary gear 114, so that the retraction of the force wheel 12 is more labor-saving and smooth, and the tensioning state of the two vortex springs 142 is easily achieved. Finally, the energy of the vortex spring 142 of the winding rope device 10 and the counterweight lower rail 23 are used to balance and cooperate to form the purpose of pulling down and positioning the curtain body 22.

On the contrary, when the curtain 22 is pushed up and folded by the counterweight lower rail 23, the user pushes the counterweight lower rail 23 upward to reduce the vertical weight of the curtain 22, and at the same time relaxes the rope 152. At this time, the elastic stress of the two spiral springs 142 is greater than the weight of the counterweight lower rail 23, so that the two spiral springs 142 will start to rebound and retract, and drive the force wheel 12 to reversely rotate. At the same time, the planetary gear 114 drives the driving gear plate 13 to rotate, and then the driving gear plate 13 is engaged with the connecting rod of the two rotating seats 14. The movable gear 141 drives the driving gear 153 of the two winding wheels 15 through the two linked gears 141, so that the two winding wheels 15 rotate and synchronously reel in the two rope bodies 152. At the same time, the high reduction ratio characteristics of the planetary gear 114 are used to increase the rotation rate of the two winding wheels 15, so that the user can easily control the curtain 22 to rise and close by lightly pushing the counterweight lower rail 23, and then the two vortex springs 142 and the counterweight lower rail 23 are mutually balanced to achieve the positioning effect of the curtain 22.

The structure of the above-mentioned specific embodiment can obtain the following benefits: (i) The winder 10 is connected with the force wheel 12 through the planetary gear 114. The high speed reduction ratio of the planetary gear 114 can effectively reduce the weight of the spiral spring 142, greatly reducing the length and volume of the spiral spring 142, which not only helps to reduce the cost of using the spiral spring 142, but also facilitates the selection and assembly of the curtain and improves the practicality of the structure.

(ii) The reel 10 is designed with a long plate shape of the bottom shell 11, so that the force wheel 12, the rotating seat 14 and the reel 15 can be assembled on the same base plane, which not only simplifies the structural design of the reel 10, but also greatly reduces the height and width of the reel 10, improves the installation applicability of the reel 10, and can effectively reduce the volume of the upper rail 21 of the curtain 20, which helps to reduce the structural cost, so as to make the reel 10 more competitive and increase the willingness of curtain manufacturers to purchase.

In summary, this creation has indeed achieved a breakthrough structural design, and has improved new content, while also being able to achieve industrial applicability and progress. Moreover, this creation has not been seen in any publication and is also novel, and should comply with the relevant provisions of the Patent Law. Therefore, a new patent application has been filed in accordance with the law, and the Jun Bureau Review Committee is requested to grant legal patent rights, and I am very grateful.
