It cannot be understood as a limitation of the utility model.
[0048] Reference Figure 1 It is a common functional sofa structure, and mainly includes seat body 1 and foot support 2 arranged on the front side of seat body 1, and at the same time, a motor element (not shown in the figure) connected with foot support 2 is arranged in seat body 1, and the motor element is used to drive foot support 2 to turn up and down and swing, so as to provide support for the legs of the user and improve the comfort of the sofa.
[0049] Based on this, when the footrest 2 is in the open state, the side of the seat 1 near the footrest 2 will open. At this time, the holes on the front side of the seat 1 may be easily invaded by foreign objects, and the holes will also expose the internal structure of the sofa, affecting its aesthetics; therefore, combined with Figure 2 Typically, a fabric strip 3 is installed between the footrest 2 and the seat 1. However, the fabric strip 3 may be clamped between the footrest 2 and the seat 1 when the footrest 2 is reset, which may affect the reset of the footrest 2. Therefore, this embodiment provides a functional sofa to overcome the above problem.
[0050] The following is in conjunction with the appendix Figures 1-8 The technical solution of this utility model will be further illustrated through specific implementation methods.
[0051] Example 1:
[0052] Reference Figure 3 This application provides a functional sofa, including a seat 1, a footrest 2, a fabric strip 3, and an elastic reset element 4. The footrest 2 is rotatably disposed on the front side of the seat 1, and provides a comfortable leg support angle for the user by lifting and swinging. The specific principle and specific setting method are not described in detail here.
[0053] At the same time, combined Figure 2 In this embodiment, the fabric strip 3 includes two parts: a leather strip part 31 and a rope part 32. One end of the rope part 32 is fixedly connected to the leather strip part 31 and is respectively disposed on opposite sides of the leather strip part 31. Meanwhile, the leather strip part 31 has a sheet structure, which allows the leather strip part 31 to cover the gap between the seat 1 and the footrest 2, thereby enclosing the bottom of the sofa.
[0054] Understandably, for ease of description, the side of the leather strap 31 away from the rope body 32 is defined as one end of the fabric strip 3, and one end of the fabric strip 3 is fixedly connected to the footrest 2; at the same time, the side of the rope body 32 away from the leather strap 31 is positioned as the other end of the fabric strip 3.
[0055] Based on this, the elastic reset element 4 is provided on the base 1. More specifically, the elastic reset element 4 is provided on the inner side wall of the base 1 and connected to the other end of the fabric strip 3. The elastic reset element 4 is used to provide elasticity to the fabric strip 3 so that the fabric strip 3 remains straight and taut during the rotation of the footrest 2, so as to prevent the fabric strip 3 from being clamped between the front of the base 1 and the footrest 2 when the footrest 2 is reset.
[0056] In the technical solution adopted in Embodiment 1 of this application, by setting an elastic reset element 4 in the seat body 1, when the footrest 2 is opened outward, the elastic reset element 4 can apply elastic force to the fabric strip 3, thereby making the fabric strip 3 taut; and when the footrest 2 is folded towards the seat body 1, the elastic reset element 4 can pull the fabric strip 3 back, thereby preventing the fabric strip from folding or piling up, so that the fabric strip 3 can pass straight through the hole on the front side of the seat body 1, and the fabric strip 3 will not be squeezed between the footrest 2, the front plate of the seat body 1 and the footrest 2. The problem of the fabric strip 3 being difficult to reset or not in place, which affects the aesthetics of the sofa, is solved.
[0057] Furthermore, continue to refer to Figure 3 In this embodiment, the elastic reset element 4 is an elastic band. One end of the elastic band is fixedly connected to the end of the fabric strip 3 away from the footrest 2, and the other end of the elastic band is fixedly connected to the seat body 1.
[0058] Based on the above setup, the elastic band can provide elastic traction, and under the traction of the elastic band, it can pull the fabric strip 3 back to make it taut.
[0059] In this embodiment, one end of the elastic band is fixed to the base 1 with a nail. Specifically, a nail gun is used to penetrate the elastic band and drive the nail into the inside of the armrest of the base 1, thus achieving a quick and secure installation of one end of the elastic band. Alternatively, the other end of the elastic band can be fixed to the fabric strip 3 by sewing, thereby achieving a secure installation of the elastic band. No specific installation method for the elastic band is limited here.
[0060] Example 2:
[0061] Based on Embodiment 1, features not explained in this embodiment will be explained using the explanation in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiment 1 is that the structure of the elastic reset element 4 is different.
[0062] Reference Figure 4 and Figure 5 In this embodiment, the elastic reset element 4 specifically includes a wheel 41 and a first spring 42. The wheel 41 is rotatably mounted on the base 1. Typically, the wheel 41 can be fixed on a rotating shaft, and the rotating shaft can be rotatably mounted on the base 1, thereby enabling the wheel 41 to rotate relative to the base 1.
[0063] Meanwhile, the first spring 42 has an inner end and an outer end. The first spring 42 covers the wheel body 41, and the inner end of the first spring 42 is fixedly connected to the wheel body 41. The other end of the first spring 42 is fixed to the fabric strip 3.
[0064] Based on the above structural design, when the footrest 2 rises, it can pull the first spring 42. At this time, the wheel 41 rotates accordingly, the first spring 42 loosens and extends outward with the displacement of the fabric strip 3. At this time, the first spring 42 can store energy, thereby generating an elastic force to pull the fabric strip 3, making the fabric strip 3 taut. When the footrest 2 returns to its original position, the first spring 42 releases energy, and the wheel 41 will tighten as the elastic force of the first spring 42 is released, thereby driving the fabric strip 3 to rotate and retract, so that the fabric strip 3 can be effectively returned to its original position.
[0065] Furthermore, to ensure a fixed connection between the first spring 42 and the fabric strip 3, the end of the first spring 42 has a buckle 421. In this embodiment, the buckle 421 is T-shaped. Meanwhile, the fabric strip 3 is provided with a fastening opening 321 that engages with the buckle 421. Specifically, the fastening opening 321 extends through the rope portion 32.
[0066] Based on the above structural design, by fastening the buckle body 421 into the fastening buckle, the first spring spring 42 and the fabric strip 3 are fixed to each other, which is quick and convenient to connect and easy to disassemble and adjust.
[0067] Furthermore, to make the first spring 42 more stable during extension and retraction, a first positioning notch 411 is recessed on the circumference of the wheel body 41. The first positioning notch 411 provided in this embodiment has a closed-loop structure, and its width is not less than the width of the first spring 42. This allows the first positioning notch 411 to accommodate the first spring 42. Therefore, during the extension and retraction of the first spring 42, it can be positioned by both sides of the first positioning notch 411, making the extension and retraction action more stable and reliable.
[0068] Example 3:
[0069] Based on Embodiment 1, features not explained in this embodiment will be explained using the methods described in Embodiment 1, and will not be repeated here. The difference between this embodiment and Embodiments 1 and 2 is that the structure of the elastic reset element 4 is different.
[0070] Reference Figure 6 , Figure 7 as well as Figure 8 In this embodiment, the elastic reset element 4 includes a driving gear 43, a driven gear 44, and a second spring 45. The driving gear 43 and the driven gear 44 are rotatably mounted on the base 1, and the driving gear 43 and the driven gear 44 are arranged adjacent to each other and mesh with each other. When the driving gear 43 rotates, it can drive the driven gear 44 to rotate in the opposite direction.
[0071] Meanwhile, the drive gear 43 has a winding section, one end of the fabric strip 3 is fixed to the drive gear 43 and wrapped in the winding section; specifically, the rope part 32 of the fabric strip 3 is fixedly connected to the drive gear 43 and wrapped in the winding section. At this time, during the rotation of the drive gear 43, the draw part of the fabric strip 3 can be wound up on the winding section.
[0072] In addition, the structure of the second spring 45 is the same as that of the first spring 42, and it also has an inner end and an outer end. Its structure will not be described in detail here. In one installation method, the driven gear 44 is rotatably mounted on the base 1 through a rotating shaft. The second spring 45 is sleeved on the rotating shaft, and the inner end is fixedly connected to the rotating shaft, while the outer end is fixedly connected to the driven gear 44. At this time, the second spring 45 is used to apply elastic torque to the driven gear 44, thereby providing elastic support to the driving gear 43.
[0073] The implementation principle of the above embodiment is as follows: When the footrest extends, the footrest 2 pulls the fabric strip 3 outward, the drive gear 43 rotates with the traction force, and the winding part on the drive gear 43 releases the rope part 32 of the fabric strip 3. Then the drive gear 43 drives the driven gear 44 to rotate, thereby causing the second spring 45 to generate a torque that resists its rotation. This torque acts on the drive gear 43, thereby generating a tension that tightens the fabric strip 3. When the footrest 2 returns to its original position, the traction force from the footrest and the tension force from the drive gear 43 on the fabric strip 3 gradually disappear. Under the push of the second spring 45, the drive gear 43 and the driven gear 44 rotate in opposite directions to return to their original positions, and rewind the rope part 32 of the fabric strip 3 into the winding part, thereby effectively restoring the fabric strip 3.
[0074] Optionally, refer to Figure 8 In one embodiment, the winding part can be a shaft. By winding the rope part 32 of the fabric strip 3 onto the shaft, it provides support for its extension and retraction. In this embodiment, the winding part is a second positioning notch 431. The second positioning notch 431 is located around the drive gear 43, and the width of the second positioning notch 431 is not less than the width of the rope part 32. This allows the second positioning notch 431 to accommodate the rope part 32. Therefore, during the extension and retraction of the rope part 32, it can be positioned from both sides of the second positioning notch 431, making the extension and retraction of the rope part 32 more stable and reliable.
[0075] Additionally, looking back Figure 7In this embodiment, in order to improve the connection stability between the fabric strip 3 and the drive gear 43, one end of the fabric strip 3 is fixed to the drive gear 43 by a screw 5. Specifically, a threaded hole can be provided on the periphery of the drive gear 43, and a through hole can be opened on the rope part 32 of the fabric strip 3. By passing the screw 5 through the through hole and threading it into the threaded hole, one end of the fabric strip 3 can be fixed to the main gear.
[0076] Furthermore, in this embodiment, the diameter of the driving gear 43 is larger than the diameter of the driven gear 44. Based on this setting, the relative rotation speed of the driven gear 44 can be increased, which is beneficial for the second spring spring 45 to deform quickly when subjected to force, thereby generating elastic force quickly. Correspondingly, it is also beneficial for its rapid rotation and reset.
[0077] It should be explained that the reset elastic elements in embodiments one, two and three are set into two groups and are respectively arranged on the inner walls of opposite sides inside the seat 1. The two groups of reset elastic elements are respectively connected to the two rope parts 32 on the pull strip 3, thereby providing a balanced reset pull force on both sides of the pull strip 3.
[0078] In summary, by providing different elastic reset elements 4, the problems of the front fabric strip 3 being squeezed and deformed during reset in existing functional sofas, and the fabric strip 3 not being reset properly due to long-term use, which affects the overall aesthetics of the sofa, can be effectively solved. This also provides a variety of upgrades and improvements for the front fabric strip structure of such sofas.
[0079] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
