Description

A stop-and-go roller blind mechanism with a spring built into the roller and a hand-held curtain. Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a stop-and-go curtain mechanism with a spring built into the roller and a hand-held curtain. Background Technology

[0002] Existing spring roller blinds generally include supports on both sides and a roller shaft. A spring rod is installed inside the roller shaft, and a limiting spring is sleeved on the spring rod. A spring end cap is installed at the end of the limiting spring. The rebound force of the limiting spring needs to be pre-loaded according to the size and weight of the curtain. Patent application number 201821249939.1 discloses a hand-held zebra blind. This patent has the following problems: The hand-held zebra blind includes a curtain roller shaft and a winding device. The spring sheet, spring sheet fixing plate, and spring sheet winding plate of the winding device are all set inside the support housing (the support housing is formed by the interlocking of the outer shell and the end cap). This results in a relatively thick support housing in the horizontal direction, which leads to a large gap between the side of the support housing away from the curtain and the curtain, resulting in serious light leakage at the gap and a poor user experience. In addition, the support housing for installation is formed by the interlocking of the outer shell and the end cap, which is a relatively complex structure and has a high production cost. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model provides a stop-and-go roller blind mechanism with a spring built into a roller, comprising: a mounting frame, a winding device, and a roller connected to the winding device. The roller is used to connect the curtain fabric, and the winding device is used to wind the roller. The winding device includes a rotating assembly and a spring assembly. The rotating assembly includes a fixed part fixedly connected to the mounting frame and a rotating part rotatable in its circumferential direction. The rotating part rotates synchronously with the roller, and when rotating, it has a first direction for raising the curtain fabric and a second direction for lowering the curtain fabric. The spring assembly is connected to and rotates synchronously with the rotating part, and the spring assembly is placed inside the spool. When the rotating part rotates around the second direction, the spring assembly stores potential energy. By releasing the potential energy stored in the spring assembly, the spring assembly, the rotating part, and the spool are driven to rotate and reset around the first direction, so as to raise and wind up the curtain. This utility model places the spring assembly inside the spool, which greatly reduces the thickness of the mounting frame, reduces the gap between the side end face of the mounting frame and the curtain, reduces light leakage, and the structure of the mounting frame is simple and the production cost is low.

The input shaft hole is adapted to the first output shaft. The mainspring assembly also includes a coiling spring and a rotating coiling spring shaft disposed within the housing. The coiled end of the coiling spring is connected to the rotating coiling spring shaft, and the input shaft hole is disposed at one end of the rotating coiling spring shaft.

[0009] Optionally, the fixing part includes a fixing sleeve, a manual adjustment turntable, and a fixing post. The manual adjustment turntable includes a disc body and an annular post. The fixing post is placed inside the annular post. A clamping spring is provided between the fixing post and the annular post. A first locking block is provided on the mounting bracket. A first locking groove for engaging with the first locking block is provided on the side end of the fixing post. The annular post is placed inside the fixing sleeve. A second locking block is provided inside the fixing sleeve. A locking slot corresponding to the second locking block is provided on the annular post.

In two adjacent mainspring assemblies, the second output shaft of one mainspring assembly is inserted into the input shaft hole of the other mainspring assembly and rotates synchronously.

[0012] Compared to existing technologies, this utility model features a follow-stop roller blind mechanism with the spring built into the roller shaft. By placing the spring assembly inside the roller shaft, the thickness of the mounting bracket can be significantly reduced, decreasing the gap between the side end face of the mounting bracket and the curtain fabric, thus reducing light leakage. Furthermore, the mounting bracket structure is simple and has low production costs. The rotating part includes an outer shell, which contains a plunger body. The plunger body is placed inside the roller shaft, resulting in a compact structure. The concealed design built into the roller shaft avoids increasing the gap between the curtain fabric and the mounting bracket. The structure with a manually adjustable turntable allows the user or installer to adjust the mechanism more easily.

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0028] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Example 1

[0029] Referring to Figures 1-8, Embodiment 1 of this utility model provides a stop-and-go roller blind mechanism with a spring built into a roller, including: a mounting frame 1, a winding device, and a roller 2 connected to the winding device. The roller 2 is used to connect the curtain fabric, and the winding device is used to wind up the roller 2. The winding device includes a rotating assembly and a spring assembly 4. The rotating assembly includes a fixing part 5 fixedly connected to the mounting frame 1 and a rotating part 3 that can rotate circumferentially. The rotating part 3 rotates synchronously with the roller 2. When the rotating part 3 rotates, it has a first direction that causes the curtain fabric to rise and a second direction that causes the curtain fabric to fall. The first direction and the second direction are opposite. The spring assembly 4 is connected to and rotates synchronously with the rotating part 3. The spring assembly 4 is placed inside the roller 2. When the rotating part 3 rotates around the second direction (as shown by the arrow in Figure 1), the spring assembly 4 stores potential energy. By releasing the potential energy stored in the spring assembly 4, the spring assembly 4, the rotating part 3, and the roller 2 are driven to rotate and reset around the first direction, so as to raise and roll up the curtain. The present invention places the spring assembly inside the roller, which greatly reduces the thickness of the mounting frame, reduces the gap L between the side end face of the mounting frame away from the curtain 9 and the curtain 9, reduces light leakage, and the structure of the mounting frame is simple and the production cost is low.

[0030] Referring to Figures 1-4, the rotating part 3 includes an outer shell 31, which includes a plunger body 311. The plunger body 311 is located inside the spool 2, with a compact structure and a hidden design built into the spool 2, avoiding the increase of gap between the curtain and the mounting frame. The outer shell 31 is provided with a limiting groove 312, and the inner side of the spool 2 is provided with a limiting protrusion 21 that engages with the limiting groove 312, so that the outer shell 31 can rotate synchronously with the spool 2. The rotating assembly also includes a first output shaft 6, which is eccentrically located on the side of the outer shell 31 near the mainspring assembly 4. The first output shaft 6 is used to connect to and drive the mainspring assembly 4 to store energy. When the rotating part 3 rotates, it drives the first output shaft 6 to rotate, thereby storing energy in the mainspring assembly 4 through the rotation of the rotating part 3. When the mainspring assembly 4 releases potential energy, it can drive the rotating part 3 to rotate and reset.

[0031] Referring to Figures 1, 2, 3, 4, and 6, a transmission component is provided between the first output shaft 6 and the fixed part 5. When the rotating part 3 rotates relative to the fixed part 5, it drives the first output shaft 6 to rotate through the transmission component. The winding device needs to be pre-tightened before installation (or before leaving the factory), that is, the rotating part 3 needs to be rotated a certain number of turns relative to the fixed part 5 to ensure that the curtain can be completely rolled up. The specific number of turns is set according to parameters such as the size and weight of the curtain. The transmission component includes a first connecting block 61, a second connecting block 62, and an intermediate movable block 63 disposed inside the outer casing 31. The first connecting block 61 is connected to the fixed part 5 and is provided with a square shaft 612 for insertion. The fixed part 5 is provided with a square hole 56 for insertion corresponding to the square shaft 612. The second connecting block 62 is disposed at the end of the first output shaft 6 away from the spring assembly 4. The intermediate movable block 63 is movably connected between the first connecting block 61 and the second connecting block 62. A connecting block 61 is provided with a first protrusion 611, a second connecting block 62 is provided with a second protrusion 621, and a middle movable block 63 is provided with a first sliding groove 631 that slides with the first protrusion 611 and a second sliding groove 632 that slides with the second protrusion 621. The extension directions of the first sliding groove 631 and the second sliding groove 632 are perpendicular to each other. The first connecting block 61 and the second connecting block 62 are driven by the middle movable block 63, so that when one of the first connecting block 61 and the second connecting block 62 rotates in its own circumferential direction, it drives the other connecting block to rotate in its own circumferential direction; conversely, when one of them does not rotate in its own circumferential direction, the other connecting block will not rotate in its own circumferential direction either. Thus, when the winding device and the mounting frame are installed, neither the first connecting block 61 nor the second connecting block 62 rotates in its own circumferential direction. When the rotating part 3 rotates, the second connecting block 62 rotates in the circumferential direction of the outer shell 31 but does not rotate in its own circumferential direction.

[0032] Referring to Figures 2, 3, and 7, the mainspring assembly 4 includes a housing 41. One end of the housing 41 is provided with an input shaft hole 411 for storing energy in the mainspring assembly 4. The input shaft hole 411 is adapted to a first output shaft 6, which is a square shaft, and the input shaft hole 411 is a square hole. The mainspring assembly 4 also includes a coiled spring 42 and a rotating coiled spring shaft 43 disposed within the housing 41. The coiled end of the coiled spring 42 is engaged with the rotating coiled spring shaft 43, and the input shaft hole 411 is located at one end of the rotating coiled spring shaft 43. When the rotating part 3 rotates around the second direction, it drives the first output shaft 6 to... The rotating spring shaft 43 rotates, thereby pulling out part of the coiled spring 42 to allow the spring assembly 4 to store potential energy. When the spring assembly 4 releases the potential energy, the rotating part 3, the first output shaft 6, the rotating spring shaft 43, and the coiled spring 42 are reset. In use, a counterweight can be installed on the lower curtain rod to increase the counterweight. When the curtain is manually suspended, the weight of the curtain and the winding force of the spring assembly 4 are balanced. When the curtain is pushed upward, due to the loss of balance, the winding force of the spring assembly 4 is greater than the weight of the curtain. At this time, the potential energy is released to realize the function of raising the curtain. In use, pulling the lower curtain rod can stop the curtain as needed.

[0033] Referring to Figures 2-5, the fixing part 5 includes a fixing sleeve 51, a manual adjustment turntable 52, and a fixing post 53. The manual adjustment turntable 52 includes a disc body 521 and an annular post 522. The fixing post 53 is placed inside the annular post 522. A clamping spring 54 is provided between the fixing post 53 and the annular post 522 to clamp the fixing post 53 and the annular post 522. Two clamping springs 54 are provided to ensure sufficient clamping force. A first locking block 101 is provided on the mounting bracket 1 by bending. A first locking groove 531 for engaging with the first locking block 101 is provided on the side end of the fixing post 53. The annular post 522 is placed inside the annular post 522. Inside the fixed sleeve 51, a second locking block 511 is provided. The annular column 522 is provided with a locking slot 5221 corresponding to the second locking block 511, so that the annular column 522 and the fixed sleeve 51 are limited when they rotate relative to each other. The fixed sleeve 51, the annular column 522, the clamping spring 54 and the fixed column 53 are all placed inside the outer shell 31, which is compact. The outer shell 31 and the spring assembly 4 are connected by a snap-fit ​​structure 8, which is convenient for assembly. Users or installers can manually pre-tighten the spring assembly by manually adjusting the turntable 52, and the tightening amount can be adjusted by themselves, so as not to waste the number of tightening turns of the spring assembly.

[0034] Referring to Figures 1, 2, 3, and 7, the mounting bracket 1 is a sheet-like body with a small thickness to reduce light leakage. The mounting bracket 1 is a bent metal sheet, simple in structure and low in production cost. One or more mainspring assemblies 4 are arranged axially. When multiple mainspring assemblies 4 are arranged, adjacent mainspring assemblies 4 are connected by snap-fit. Each end of the mainspring assembly 4 has a matching input shaft hole 411 and a second output shaft 40. The second output shaft 40 is integrally formed on the end of the rotating coil spring shaft 43 away from the input shaft hole 411. In two adjacent mainspring assemblies 4, the second output shaft 40 of one mainspring assembly 4 is connected to... Another spring assembly 4 has an input shaft hole 411 that can be inserted and rotated synchronously. Multiple spring assemblies 4 can be set to increase the curtain's rewinding force, so that wide and large curtains can be rolled up, making it widely applicable. The number of spring assemblies 4 can be set according to parameters such as the size and weight of the curtain and the rewinding force of the spring assemblies 4. The setting method of the coil spring 42 is as follows: narrow / thin coil springs 42 can be used for small curtains; wide / thick coil springs 42 can be used for large curtains to increase the rewinding torque. The number of spring assemblies 4 can be set accordingly based on the matching of the rewinding force of different coil springs 42 with the rewinding force required by different curtains, making it more flexible to use. Example 2

[0035] Referring to Figures 9-11, the main difference between this second embodiment and the first embodiment is that: the fixing part 5 includes a fixing shaft 55, a first connecting block 61 is integrally connected to one end of the fixing shaft 55, a first locking block 101 is provided on the mounting bracket 1, a second locking groove 551 for engaging with the first locking block 101 is provided on the side end of the fixing shaft 55, a locking pin 7 is detachably inserted into the outer shell 31, and a plurality of third locking grooves 552 corresponding to the locking pin 7 are arranged in a ring on the fixing shaft 55. One end of the locking pin 7 passes through the outer shell 31 and is locked into one of the third locking grooves 552 for limitation, so as to restrict the relative rotation of the fixing shaft 55 and the outer shell 31; the winding device in this second embodiment can pre-tighten the spring assembly before leaving the factory and lock this tightening force by locking pin 7. When the user or installer installs, he only needs to pull out the locking pin 7 to use this tightening force without re-tightening, making the installation more convenient.

[0036] This utility model features a self-stopping roller blind mechanism with the spring built into the roller shaft. By placing the spring assembly inside the roller shaft, the thickness of the mounting bracket can be significantly reduced, decreasing the gap between the side end face of the mounting bracket and the curtain fabric, thus reducing light leakage. Furthermore, the mounting bracket has a simple structure and low production cost. The rotating part includes an outer shell, which contains a plunger body. The plunger body is placed inside the roller shaft, resulting in a compact structure. The concealed design built into the roller shaft avoids increasing the gap between the curtain fabric and the mounting bracket. The structure with a manually adjustable turntable allows users or installers to... The mainspring assembly can be pre-tightened manually via a dial adjustment, and the tightening amount is adjustable, minimizing wasted winding turns. The structure with a locking pin allows for pre-tightening of the mainspring assembly at the factory, with the locking pin securing this tightening force. During installation, users or installers simply pull out the locking pin to utilize this tightening force without needing to re-tighten, making installation more convenient. The number of mainspring assembly units can be set according to the matching of different spring rewinding forces with the required rewinding force of different curtains, providing greater flexibility.

[0037] This utility model also provides a hand-held curtain, including the aforementioned mechanism for stopping and starting the curtain with the spring built into the roller. This hand-held curtain also has the beneficial effects of the aforementioned mechanism for stopping and starting the curtain with the spring built into the roller, which will not be described in detail here.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
