Description

Technical Field

[0001] This utility model relates to the field of furniture, specifically to a base and a sofa bed. Background Technology

[0002] Sofa beds can switch between sitting and reclining positions, facilitating use in various scenarios. Existing sofa beds include a base and a backrest. The base comprises a pedestal and a movable seat, the position of which is adjustable to allow switching between sitting and reclining positions. The movable seat and pedestal are interconnected and their relative positions can be adjusted under the guidance of connecting components. These connecting components need to possess both good connection strength and adjustment precision. Existing connecting components suffer from overly complex structures, leading to cumbersome disassembly and maintenance, requiring users to spend more time and effort on assembly and maintenance. Furthermore, they lack sufficient precision in guiding the adjustment, resulting in uneven adjustment of the movable seat and negatively impacting the user experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a base and sofa bed with a sliding component. The sliding component is set between the movable seat and the base. The sliding component slides along the slide rail and guides the movable seat to move and adjust precisely. This simplifies the structure to facilitate assembly and maintenance, effectively improves adjustment accuracy, ensures smooth guidance, and enhances the user experience.

[0004] This utility model is achieved through the following method: a base with a sliding assembly, comprising a base and a movable seat. The base includes two opposing armrests, which enclose a channel for the movable seat to move back and forth. The two sides of the movable seat are mounted on the corresponding armrests via a sliding assembly. The sliding assembly includes a slide rail on the side wall of the armrest and a sliding member on the side edge of the movable seat. The sliding member slides along the slide rail and guides the movable seat to reciprocate back and forth along the channel. By providing a sliding assembly between the movable seat and the base, and allowing the sliding member to slide along the slide rail and guide the movable seat to precisely reciprocate along the channel for adjustment, this design simplifies the structure, facilitates assembly and maintenance, reduces production costs, effectively improves adjustment accuracy, ensures smooth guidance, and enhances the user experience.

[0005] Preferably, the slide rail is shaped with a higher front and a lower back. The sliding member slides back and forth along the slide rail and drives the movable seat to switch between a lying position and a sitting position. This can guide the movement of the sliding member and also use the inclined slide rail to guide the sliding member to switch to a sitting position.

[0006] Preferably, the sliding member is located on the rear edge side of the movable seat. The sliding member slides back and forth along the slide rail to adjust the height of the rear edge of the movable seat, so that the angle between the top surface of the movable seat and the horizontal plane is adjustable. The sliding member can slide along the slide rail, which is used to guide the movable seat to move back and forth and switch between sitting and lying positions, and can also adjust the angle between the movable seat and the horizontal plane to provide comfortable support for the user.

[0007] Preferably, when the movable seat is in a reclining position, the sliding member is located at the front end of the slide rail, and the top surface of the movable seat is parallel to the horizontal plane. When the movable seat is in a reclining position, the sliding member is located at the front end of the slide rail, causing the rear edge of the movable seat to rise and keeping the top surface horizontal, providing stable support for the user.

[0008] Preferably, when the movable seat is in a seated position, the sliding member is located at the rear end of the slide rail, and the top surface of the movable seat is inclined with the front higher than the rear. When the movable seat is in a seated position, the sliding member is located at the rear end of the slide rail, which lowers the rear edge of the movable seat, making it easier for the user to lean back and have their back contact the backrest.

[0009] Preferably, the front end of the slide rail is bent downwards to form a front locking position, and the sliding member moves to the front locking position and is locked in place. The downward bending of the front locking position allows the sliding member to be locked in the front locking position by its own weight, preventing the sliding member from disengaging from the front locking position and ensuring that the movable seat is positioned in a lying position.

[0010] Preferably, the rear end of the slide rail is bent downwards to form a rear latch, and the sliding member moves to the rear latch and is locked in place. The downward bending of the rear latch allows the sliding member to be locked in the rear latch by its own weight, preventing the sliding member from disengaging from the rear latch and ensuring that the movable seat is positioned in a sitting position.

[0011] Preferably, the slide rail is a long, vertical strip with a groove along its length in the middle to guide the sliding component. The sliding component includes a vertically placed connecting plate and a sliding pin on the outer wall of the connecting plate. The connecting plate is vertically offset from the slide rail and closely fitted to it, allowing the sliding pin to be slidably inserted into the groove. The groove has a top wall and a bottom wall, which guide and limit the sliding pin inserted into the groove, preventing the sliding component from detaching from the slide rail. The connecting plate can be connected to a movable seat, thereby guiding and limiting the movable seat.

[0012] Preferably, the inner wall of the connecting plate is provided with a pin, and the rear edge of the movable seat is provided with a hook. The hook is detachably hooked to the pin, so that the movable seat and the sliding component move back and forth. The movable seat is detachably hooked to the pin by the hook, which not only facilitates the disassembly, packaging and transportation of the movable seat and the base, improving the convenience of disassembly and assembly, but also makes it convenient for users to snap the movable seat and the base together, ensuring that the movable seat can move and switch along a preset path under the guidance of the sliding component.

[0013] Preferably, there are at least two sliding pins, each with a bushing that abuts against the slide rail to reduce frictional resistance between them. The two sliding pins, inserted within the slide groove, not only limit the rotation of the connecting plate, ensuring its stability and preventing deflection, but also improve the reliability of the connection between the sliding component and the slide rail, thus enhancing guiding accuracy. The bushing is preferably a plastic sheet, which reduces frictional loss and noise.

[0014] Preferably, the bottom of the front edge of the movable seat is provided with rollers, which overlap the ground so that the top surface of the movable seat forms an upward supporting surface. The rollers not only support the front edge of the movable seat, but also reduce the resistance when the movable seat moves back and forth, making it convenient for the movable seat to switch freely between sitting and lying positions.

[0015] A sofa bed includes a base, the rear of which is provided with a backrest. When the seat is in a sitting position, the backrest cooperates with the base to provide support for the user's back.

[0016] Preferably, the backrest is positioned between the rear edges of the armrests, and the front wall of the backrest forms a backrest surface. This ensures that the backrest and armrests are firmly connected, thereby ensuring that the relative position between the backrest and the movable seat is suitable for the user to sit in. It also provides vertical back support for the user's back by utilizing the forward-facing backrest surface.

[0017] The beneficial effects of this utility model are as follows: A sliding component is set between the movable seat and the base. The sliding component slides along the slide rail and guides the movable seat to move back and forth precisely along the channel for adjustment. This simplifies the structure to facilitate assembly and maintenance, reduces production costs, effectively improves adjustment accuracy, ensures smooth guidance, and enhances the user experience.

[0025] The essential features of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] This embodiment provides a base with a sliding component.

[0028] like Figure 1 and 2 The base shown includes a base and a movable seat 2. The base includes two opposing armrests 1, which enclose a channel for the movable seat 2 to move back and forth. The two sides of the movable seat 2 are mounted on the corresponding armrests 1 via sliding components. Each sliding component includes a slide rail 3 on the side wall of the armrest 1 and a sliding member 4 on the side edge of the movable seat 2. The sliding member 4 slides along the slide rail 3 and guides the movable seat 2 to reciprocate back and forth along the channel. By providing a sliding component between the movable seat 2 and the base, and allowing the sliding member 4 to slide along the slide rail 3 and guide the movable seat 2 to precisely reciprocate along the channel for adjustment, the base simplifies the structure, facilitating assembly and maintenance, reducing production costs, effectively improving adjustment accuracy, ensuring smooth guidance, and enhancing the user experience.

[0029] In this embodiment, the bottom front edge of the movable seat 2 is provided with a roller 12, which rests on the ground so that the top surface of the movable seat 2 forms an upward supporting surface. The sliding member 4 is provided on the side of the rear edge of the movable seat 2. The front edge of the movable seat 2 is supported by the roller 12, and the rear edge is supported by the sliding member 4. The movable seat 2 can switch between a lying position and a sitting position by moving back and forth. This ensures that the movable seat 2 can move accurately and switch states, and also reduces the resistance when the movable seat 2 moves by using the roller 12 and the sliding member 4, thereby facilitating the user's switching operation.

[0030] In this embodiment, the slide rail 3 is shaped with a higher front and a lower rear. The sliding member 4 slides back and forth along the slide rail 3, driving the movable seat 2 to switch between a reclining and sitting position. The sliding member 4 slides back and forth along the slide rail 3, adjusting the height of the rear edge of the movable seat 2 so that the angle between the top surface of the movable seat 2 and the horizontal plane is adjustable. The slide rail 3 is a straight line with an incline, which effectively reduces the resistance when the sliding member 4 moves and allows for the adjustment of the height of the sliding member 4. This allows the movable seat 2 to control the angle between its top surface and the horizontal plane by adjusting the height of its rear edge, providing comfortable support for the user.

[0031] In this embodiment, when the movable seat 2 is in a seated position, the sliding member 4 is located at the rear end of the slide rail 3, and the top surface of the movable seat 2 is inclined, with the front higher than the rear. As the sliding member 4 moves backward along the slide rail 3 and lowers in height, the rear edge of the movable seat 2 also lowers in height and switches to a seated position. At this time, the front edge of the movable seat 2 is higher than the rear edge, forming an inclined support surface. When the user sits on this support surface, the user's weight is converted into a backward force through the support surface, causing the user to lean against the backrest and press their back against it, effectively improving seating comfort.

[0032] In this embodiment, when the movable seat 2 is in a reclining position, the sliding member 4 is located at the front end of the slide rail 3, and the top surface of the movable seat 2 is parallel to the horizontal plane. As the sliding member 4 moves forward along the slide rail 3 and increases in height, the rear edge of the movable seat 2 also increases in height and switches to a reclining position. At this time, the front and rear edges of the movable seat 2 are set at the same height, forming a horizontal support surface. When the user lies on the support surface, it effectively prevents the user from slipping, effectively improving the comfort of the reclining position.

[0033] In this embodiment, since the slide groove 7 is straight, it effectively reduces the resistance of the sliding member 4 during sliding and improves the convenience of switching. However, in order to improve the positioning reliability of the sliding member 4 after sliding into place, a front fastener 5 and a rear fastener 6 are respectively provided at the front end and rear end of the slide rail 3 (e.g., Figure 3 As shown), the sliding member 4 can be positioned after sliding into place, thereby ensuring that the movable seat 2 is locked in a lying or sitting position. Specifically, the front end of the slide rail 3 is bent downward to form a front buckle 5. The bottom of the connection between the front buckle 5 and the middle section of the slide rail 3 is provided with an upwardly raised front limiting part. The sliding member 4 moves to the front buckle 5 and is locked and positioned by the front limiting part (as shown). Figure 5As shown, the sliding member 4 uses the weight of the movable seat 2 to restrict its upward movement and its crossing of the front limiting part, thereby ensuring that the movable seat 2 is locked in a reclining position. The rear end of the slide rail 3 is bent downward to form a rear buckle 6. The bottom of the connection between the rear buckle 6 and the middle section of the slide rail 3 is provided with an upwardly raised rear limiting part. The sliding member 4 moves to the rear buckle 6 and is locked in place by the rear limiting part. The sliding member 4 uses the weight of the movable seat 2 to restrict its upward movement and its crossing of the rear limiting part, thereby ensuring that the movable seat 2 is locked in a sitting position.

[0034] In this embodiment, the slide rail 3 is a long, vertical strip. A groove 7, guiding the sliding member 4, is formed along the length of the slide rail 3. The sliding member 4 includes a vertically placed connecting plate 8 and sliding pins 9 disposed on the outer wall of the connecting plate 8. The connecting plate 8 is vertically offset from and adjacent to the slide rail 3, allowing the sliding pins 9 to be slidably inserted into the groove 7. The slide rail 3 has multiple mounting holes, and bolts are used to secure it to the side of the armrest 1. A clearance groove is formed on the side of the armrest 1 corresponding to the groove 7, to conceal part of the sliding pins 9 and the bushing 13 within the armrest 1. This reduces the support gap between the movable seat 2 and the armrest 1, thereby reducing the space requirements for assembly of the slide rail 3.

[0035] In this embodiment, there are at least two sliding pins 9, and each sliding pin 9 is provided with a bushing 13 that abuts against the slide rail 3 (e.g., Figure 4 (As shown), to reduce the frictional resistance between the sliding pin 9 and the slide rail 3. The sliding pin 9 passes through the slide groove 7 and makes the connecting plate 8 adjacent to the slide rail 3. This ensures that the connecting plate 8 can move back and forth along the slide rail 3 under the guidance of the sliding pin 9, and also reduces the assembly space requirements by reducing the distance between the connecting plate 8 and the slide rail 3. This effectively reduces the distance between the side wall of the movable seat 2 and the side wall of the armrest 1, improving assembly accuracy. There are two sliding pins 9, and each sliding pin 9 abuts against the groove wall of the slide groove 7 for limitation. This effectively improves the guiding reliability of the connecting plate 8 and the slide rail 3, and also prevents the connecting plate 8 from deflecting relative to the slide rail 3, thus ensuring that the connecting plate 8 can slide along the slide rail 3 in a fixed posture.

[0036] In this embodiment, the inner sidewall of the connecting plate 8 is provided with a pin 10 (e.g., ...). Figure 6 As shown, the movable seat 2 has a hook 11 on its rear edge side. The hook 11 is detachably hooked onto the pin 10 to enable the movable seat 2 and the sliding member 4 to move back and forth. The movable seat 2 is detachably fastened to the pin 10 of the sliding member by the hook 11, which effectively improves the convenience of disassembly and maintenance. It allows for independent packaging and transportation of the base and the movable seat 2 through disassembly, and also ensures that the movable seat 2 can be accurately installed between the armrests 1 to meet usage requirements.

[0037] Example 2:

[0038] Compared to Embodiment 1, this embodiment provides a sofa bed.

[0039] As shown in the figure, a sofa bed includes a base, and a backrest is provided at the rear of the base. When the movable seat 2 is switched to a sitting position, it can cooperate with the backrest to provide support and reclining for the user, effectively improving sitting comfort.

[0040] In this embodiment, the backrest is disposed between the rear edges of the armrest 1, and the front wall of the backrest forms a backrest surface, which not only ensures that the backrest and the armrest 1 are firmly connected, thereby ensuring that the relative position between the backrest and the movable seat 2 is suitable for the user to sit, but also provides vertical backrest support for the user's back by using the forward-facing backrest surface.

[0041] When in use, as the movable seat 2 moves forward, a large gap will be created between the rear edge of the movable seat 2 and the backrest. The gap can be sealed by placing a filling bag, so that the filling bag is flush with the top surface of the movable seat 2 and forms a flat support surface.

[0042] In this embodiment, the movable seat 2 is provided with a forward-movable extension, and the extension is provided with a liftable pillow. When the extension moves forward to the front of the movable seat 2, the pillow can be lifted by the support mechanism and smoothly connected to the top surface of the movable seat 2, and combined with the top surface of the filling bag to form a support surface for the user to lie on.

[0043] The other structures and effects of the base described in this embodiment are the same as those in Embodiment 1, and will not be repeated here.
