Description

Technical Field

[0001] The present invention relates to the field of curtains, and particularly to a roller device for curtains and a curtain.

Background Art

[0002] Vertical blinds are named because the blades are suspended vertically one by one on the upper rail, and the amount of light can be freely adjusted left and right to achieve light shielding. It is popular among young people in modern interiors and is also called a dreamy vertical curtain because each individual leaf is independent and can be passed through. The vertical curtain adopts a blind structure, and the blades can rotate, so not only can the amount of light in the room be freely adjusted, but ventilation and air exchange can also be achieved, and the purpose of light shielding can be achieved, so it is favored by modern young people. In actual applications, a combination of a single-hook roller and a parent-child hook type hanging plate is adopted. The adjacent curtain units are continuously combined using the parent-child hook type hanging plate to form a vertical curtain cloth for one side, and then it is suspended on a plurality of single-hook rollers slidably connected to the rail. The movement and rotation of the roller are controlled by a transmission mechanism, thereby realizing the opening and closing of the entire vertical curtain and the adjustment of the amount of light. A curtain integrating cloth and net is a product expected by consumers. The thinner the net part, the better, and the more delicate it is, the better. The thicker the fabric part, the better, and it is required to have high sound insulation and excellent light shielding properties.

[0003] For the curtain fabrics currently on the market, when dirt adheres, it is necessary to open the snap-button fastener to wash and then fasten it again. When an individual curtain unit is damaged, it is also necessary to open the fastener to replace it with a new unit and then fasten it again. Such frequent opening and closing of the fastener not only causes loosening and damage after long-term use, but is also inconvenient for the user to replace quickly. Furthermore, a gap occurs between the conventional roller device for curtains and the curtain fabric, so it is easy for light and wind to pass through, and the light shielding effect is significantly reduced.

[0004] For example, the Chinese utility model application number 201721777911.0 discloses a roller device for curtains. This device includes a body and gears, the gears comprising a first transmission gear. The first transmission gear is rotatably fixed to the body, and the distance from its axis to the edge of the body is smaller than the radius of the gear's vertex circle. Furthermore, it includes a worm gear and a worm wheel, with a blade fixing clip provided below the worm wheel. The rotation of the worm gear drives the worm wheel, causing the blade fixing clip to rotate. A guide groove is provided at the bottom of the body, and belt fixing holes and spacer fixing holes are located on the sides. In this technical solution, the blades are not affected by wind, and even if some blades get caught, it does not affect the direction of the other blades, making it applicable to arched windows. It has low operating resistance, low noise, and a long lifespan. Because the torque required to rotate the blades is small, it can be used for larger and heavier curtains. However, it does not solve the aforementioned technical problems of rapid removal and replacement of curtain fabric and improvement of the curtain's light-blocking effect. [Overview of the project] [Problems that the invention aims to solve]

[0005] The technical problem that this invention aims to solve is to overcome the shortcomings of existing technologies and provide a ball guide device and curtain for curtains. When replacing a damaged or soiled curtain fabric, the hanger plate can be easily removed from the hook by hand, eliminating the inconvenience of frequently opening and closing snap-button type hanger plates to change curtains. The hanging components are highly flexible and can be washed together with the curtain fabric, eliminating the need to disassemble the hanging components and curtain fabric for washing and replacement. The upper edge of the curtain fabric is designed to be 0-10 mm higher than the upper edge of the hanging plate, thereby covering the gap between the upper edge of the curtain fabric and the curtain rail, and significantly improving light blocking and heat insulation. The combination of adjustment components and through holes allows for adjustment of the inclination angle between the hanging plate and the curtain fabric, enabling the curtain fabric to be used more vertically.

[0006] This invention provides a ball guide device for curtains and a curtain in order to solve the drawbacks of existing technologies, such as the difficulty in removing curtain fabric and the low light-blocking effect. [Means for solving the problem]

[0007] To solve the above technical problems, this invention is resolved by the following technical solution. The curtain ball guide device includes a partition and two hanging plates positioned symmetrically below the partition. The ends of the two hanging plates curve upward to form hooks, and the two hooks are positioned facing each other. A vertical limiting strip is provided in the center of the hanging plates, which passes through the hooks and divides them into a left hook section and a right hook section. The ball guide device further includes a hanging piece that fits onto the hooks. The center of the hanging piece is provided with a left hook groove and a right hook groove that fit onto the left hook body and the right hook body, respectively, and through holes are provided at the top of the left hook groove and the right hook groove that pass through them. By using the two hooks and two hook plates in combination, the user can easily hang and detach the hook plates from the hooks. The two hook plates are independent and have no connection relationship; they are simply connected to the hooks. When the curtain fabric is damaged or soiled and needs to be replaced, the hook plates can be easily removed from the hooks by hand, avoiding the inconvenience of frequently opening and closing snap-button type hook plates to change the curtains. The left hook body, the right hook body, and the left hook groove and right hook groove work together to securely hold the curtain fabric and prevent it from falling.

[0008] In a preferred embodiment, the ball guide device includes two suspension plates and two suspension plate pieces that fit them, to which curtain fabric is attached. The connection method is by sewing, heat welding, adhesive, or welding. The method of connecting the curtain fabric and the suspension plates can be customized according to the user's needs, and each different fastening method has its own advantages and disadvantages. The user can select a different connection method based on their actual needs and achieve different connection effects. This ensures that the fastening is robust and resistant to loosening.

[0009] In a preferred embodiment, the hanging plate is thin, and the upper end of the hanging plate is 0-10 mm lower than the upper end of the curtain fabric. The hanging plate is highly flexible and can be washed together with the curtain fabric, eliminating the need to disassemble, wash, or replace the hanging plate and curtain fabric. Therefore, products combining this hanging plate and curtain fabric can be mass-produced in advance as standard parts, reducing the operating costs of companies and contributing to the conservation of social resources, reduced energy consumption, and environmental protection. With conventional curtain fabrics, a gap is created between the upper end of the curtain fabric and the rail after installation, and this area significantly reduces the light-blocking and heat-insulating functions. In this invention, the upper end of the curtain fabric is set 0-10 mm higher than the upper end of the hanging plate, thereby covering the gap and significantly improving the light-blocking and heat-insulating properties of the curtain.

[0010] In a preferred embodiment, the widths of the left hook groove and the right hook groove are set wider than the widths of the left hook body and the right hook body. By setting the widths of the hook and the hook grooves on the hook plate in this way, the hook can easily fit into the inside of the hook groove and its position can be smoothly deflected within the groove.

[0011] Preferably, the ball roller device further includes a connecting member provided on the upper part of the partition plate and a ball groove that fits therein. The ball groove moves the hanging plate and the hanging plate on the curtain rail, thereby moving the curtain fabric. The curtain rail is long and narrow, with a transmission mechanism provided at both ends of the rail, the inside of the rail is hollow, and a belt groove is provided on the side wall of the rail along the axial direction. A fixed gear is provided on the upper part of the hanging plate, and the transmission mechanism drives the belt mechanism to rotate the gear, thereby rotating the hanging plate.

[0012] Preferably, the through-hole is provided with an adjustment member for adjusting the inclination angle between the hanging plate and the curtain fabric. Due to errors in actual production and installation, vertical curtains need to remain as vertical as possible. However, because the fabric is elastic, some distortion occurs when it falls vertically, and there is no guarantee that the curtain will be 100% vertical. For this reason, it is necessary to adjust the hanging angle of the curtain fabric to maintain a state that is as vertical and uniform as possible when in use. The width of the left hook groove and the right hook groove are wider than the width of the left hook body and the right hook body, so the hooks can move freely within the grooves. To tilt the curtain fabric to the left, rotate or insert the adjustment part into the through-hole on the left side. This causes the left hook body to become lower on the left and higher on the right side due to the downward pressure of the adjustment part, and the hanging plate tilts the curtain fabric to the left. Similarly, to tilt the curtain fabric to the right, rotate or insert the adjustment part into the through-hole on the right side. At this time, the downward pressure of the adjustment part causes the right hook body to become lower on the right and higher on the left side, tilting it to the right. The downward rotation angle of the adjustment component and the insertion depth into the through hole can be adjusted as needed.

[0013] The curtain includes the curtain running device described above, with multiple curtain running devices installed within the curtain rail. The device moves left and right along the curtain rail and rotates by a certain angle through the action of a drive mechanism, thereby moving the curtain fabric left and right and rotating by a certain angle. One of the objectives of this invention is to enable easy removal of the curtain fabric, satisfying the needs for replacement and washing, thereby significantly reducing costs and avoiding the inconvenience of frequently unfastening snap buttons. Consumers can easily replace the fabric at home, and the curtain fabric can be freely changed to match the atmosphere of various holidays. Even if the curtain fabric becomes old, dirty, or no longer suits the user's taste, it can be freely replaced with a favorite color or design to match the atmosphere of various holidays, allowing for the decoration of the indoor environment. This invention is not only highly suitable for younger generations of consumers but also for older generations with a strong focus on saving money, enabling mass production in advance and reducing the operating costs of businesses. Furthermore, it contributes to the conservation of social resources, reduction of energy consumption, and environmental protection.

[0014] As an optimal solution, the curtain fabric is arranged with alternating light-blocking and light-transmitting sections. The light-transmitting sections are made of a thin mesh that allows light to pass through, while the light-blocking sections are made of opaque fabric. When adjacent light-blocking sections rotate to a horizontal position, the entire curtain becomes light-blocking, and when they rotate to a vertical position, it becomes light-transmitting. When the light-blocking and light-transmitting sections rotate to a certain angle, the curtain exhibits different light-blocking states, and the user can adjust the angle of the light-blocking and light-transmitting sections according to their actual needs to control the light-blocking state of the curtain.

[0015] In a preferred embodiment, adjacent hanging plates installed on two adjacent curtain roller devices are connected to the same curtain fabric. The first roller device is suspended by left and right hanging plates, and the adjacent second roller device is also suspended by left and right hanging plates. The right hanging plate of the first roller device and the left hanging plate of the adjacent second roller device are connected to the left and right ends of the same curtain fabric, and so on. The user can use different numbers of roller devices depending on the width of the window.

[0016] Preferably, the partition plate, the connecting component at the top of the partition plate, and the hanging plate at the bottom of the partition plate are integrally molded. Integral molded components allow for a stronger connection, and users can select different connecting components and ball guide grooves depending on the curtain rail. [Effects of the Invention]

[0017] By adopting the above-described technical solution, this invention has the following remarkable technical effects. (1) If the curtain fabric is damaged or soiled and needs to be replaced, the hanger plate can be easily removed from the hook by hand, eliminating the hassle of frequently opening and closing the snap-button hanger plate to change the curtain. The hanger plate is highly flexible and can be washed together with the curtain fabric, eliminating the need to disassemble the hanger plate and curtain fabric for cleaning and replacement. (2) The top edge of the curtain fabric is designed to be 0-10 mm higher than the top edge of the hanging board, which covers the gap between the top edge of the curtain fabric and the rail, greatly improving light blocking and heat insulation. (3) The interlocking design of the adjustment part and the through hole is used to adjust the inclination angle between the suspension plate and the curtain fabric, thereby improving the perpendicularity of the curtain fabric.
