Description

Technical Field

[0001] This utility model relates to the field of sofa technology, and in particular to a sofa with an inward-rolling iron frame. Background Technology

[0002] Sofas are a common type of furniture, mainly used in living rooms, lounges, or reception areas, where people can sit down to rest, relax, or receive guests. Traditional sofas typically rely on air conditioning or fans for cooling during the summer. However, in the absence of these systems, it's difficult to cool people down, which can easily cause discomfort and stuffiness. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technology where traditional sofas are typically cooled by indoor air conditioning or fans during the summer. However, if there are no air conditioning or fans in the room, it is inconvenient to cool people down, which can easily cause users to feel stuffy and uncomfortable. Therefore, this invention proposes a sofa with an inward-rolling iron frame.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A sofa with an inward-rolling iron frame includes a seat, armrests are fixedly provided on both sides of the seat, a backrest is fixedly provided on the inner wall of one side of the seat, a first hinge seat is fixedly provided on one side of the seat, and a footrest iron frame is hinged to the first hinge seat. The same cushion is fixedly provided on the footrest iron frame and the seat.

[0006] A comfort mechanism is installed on one of the handrails to provide ventilation for people in the summer.

[0007] The adjustment mechanism, located on the armrest, is used to adjust the height of the comfort mechanism and can be stored away when not in use.

[0008] In one possible design, the comfort mechanism includes a blower box and a blower for blowing air. The blower box has multiple air holes on one side and a square hole on one side of the bottom. The blower's air outlet is fixedly connected to the bottom of the blower box, and the blower's air outlet covers the square hole.

[0009] In one possible design, the adjustment mechanism includes a concave plate, a lifting plate, and a first electric push rod. One side of the concave plate is fixedly connected to one side of one of the handrails. The outer side of the lifting plate is slidably connected to the inner wall of the concave plate. One end of the first electric push rod is fixedly connected to the bottom of the concave plate. The telescopic part of the first electric push rod passes through the bottom of the concave plate and is fixedly connected to the bottom of the lifting plate. A cover is hinged to one side of the concave plate.

[0010] In one possible design, a bearing for adjusting the blowing angle is fixedly installed on the top of the lifting plate, a rod is fixedly installed on the inner wall of the inner ring of the bearing, the bottom of the blower box is fixedly connected to the top of the rod, and a fixing ring is fixedly sleeved on the rod.

[0011] In one possible design, the fixing ring has a circular hole, and the inner wall of the circular hole is slidably connected to a plug rod for fixing the blowing angle. The top of the lifting plate has multiple plug holes, and the bottom end of the plug rod is inserted into the plug holes, which are arranged in a ring.

[0012] In one possible design, the seat has a receiving groove, and a second electric push rod for driving the footrest frame to unfold or roll inward is fixedly installed on one inner wall of the receiving groove. An L-plate is slidably connected to the bottom inner wall of the receiving groove, and a second hinge seat is fixedly installed on one side of the top of the L-plate. A connecting plate is hinged to the second hinge seat, and a third hinge seat is fixedly installed on the inner side of the footrest frame. One end of the connecting plate is hinged to the third hinge seat.

[0013] In this application, the footrest frame is initially in an inward-curling state (the footrest frame is closed on one side of the seat, equivalent to "folding"). During summer use, the user manually opens the cover to expose the internal comfort mechanism (air blower). The user activates the first electric push rod as needed. The telescopic part of the first electric push rod extends or retracts, causing the lifting plate to slide and rise on the inner wall of the concave plate. When the comfort mechanism (air blower and fan) reaches the appropriate height, the first electric push rod stops working, and the comfort mechanism remains at that height. When angle adjustment is needed, the user manually pulls up the insert rod, disengaging it from the insertion hole of the lifting plate. Then, the air blower is manually rotated, causing the rod to rotate via the bearing, thereby changing the air blowing angle of the air blower. When the air blower is rotated to the appropriate angle and the insert rod is aligned with the insertion hole, the user lowers the insert rod, inserting its bottom end into the corresponding insertion hole on the top of the lifting plate, thus fixing the air blowing angle of the air blower. Then, the user starts the fan. The fan starts working, blowing air onto the person through the air vents on the air box for added comfort. When the footrest frame needs to be unfolded, the second electric push rod is activated. The telescopic part of the second electric push rod extends, pushing the L-plate to slide on the bottom inner wall of the receiving groove. The movement of the L-plate drives the second hinge seat to move, which in turn pushes the footrest frame to rotate and unfold around the first hinge seat through the connecting plate. When the footrest frame is unfolded to the appropriate position, the second electric push rod stops working, and the footrest frame remains unfolded. When the comfort mechanism is not needed, the fan power is turned off, and the first electric push rod is activated, causing the lifting plate to descend and lowering the comfort mechanism to its lowest position (retracted into the concave plate). The user manually closes the cover, sealing the comfort mechanism inside. The surface of the cover can be used to place items, such as teacups. It should be noted that the fan, the first electric push rod, and the second electric push rod require an external controller and an external power supply for operation.

[0014] In this utility model, the sofa with the iron frame roll-up function can blow air onto the person sitting on the sofa in summer by means of the fan and blower box in the comfort mechanism. This solves the problem that traditional sofas are not convenient to cool people down in summer when there is no air conditioning or fan, which can easily make users feel stuffy and uncomfortable, and improves the comfort of use.

[0015] In this invention, a sofa with an inward-rolling iron frame allows for height adjustment of the comfort mechanism by adjusting a lifting plate that slides and rises on the inner wall of a concave plate via a first electric push rod. Users can adjust the comfort mechanism to a suitable height to meet the needs of different heights and usage scenarios. When the comfort mechanism is not in use, the fan power can be turned off, the first electric push rod activated to lower the lifting plate, and the comfort mechanism lowered to its lowest position and stored inside the concave plate. The cover can then be manually closed to seal the comfort mechanism, resulting in a neat sofa appearance and allowing the cover surface to be used for placing items, thus increasing the sofa's functionality. Furthermore, the integrated directional airflow system in the armrests eliminates reliance on air conditioning / fans, making it particularly suitable for environments without air conditioning. The combination of a blower box and fan can independently achieve localized cooling, addressing the core pain point of stuffy sofas in summer and improving comfort. The footrests are electrically retracted and completely closed to the side of the seat, reducing space occupation by 30%-50% compared to traditional fixed footrests, significantly enhancing its suitability for small apartments.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1-5 A sofa with a roll-up iron frame, used in the sofa industry, comprises: a seat 4, armrests 1, backrest 2, footrest iron frame 15, seat cushion 3, a comfort mechanism, an adjustment mechanism, and a drive structure for driving the footrest iron frame 15 to unfold or roll inward. Armrests 1 are fixedly mounted on both sides of the seat 4, the backrest 2 is fixedly mounted on the inner wall of one side, and a first hinge seat 14 is fixedly mounted on one side. The footrest iron frame 15 is hinged to the first hinge seat 14, and the same seat cushion 3 is fixedly mounted on both the footrest iron frame 15 and the seat 4. The comfort mechanism is located on one of the armrests 1 for providing ventilation in summer; the adjustment mechanism is also located on the armrest 1 for height adjustment of the comfort mechanism and for storage when not in use.

[0024] The comfort mechanism includes an air blower box 6 and a fan for blowing air. The air blower box 6 has multiple air vents on one side and a square hole on the bottom side. The fan's air outlet is fixedly connected to the bottom of the air blower box 6, and the fan's air outlet covers the square hole. When the fan is working, air enters the air blower box 6 through the air outlet and is blown out through the multiple air vents, thereby cooling the person sitting on the sofa.

[0025] The adjustment mechanism includes a concave plate 5, a lifting plate 9, and a first electric push rod 7. One side of the concave plate 5 is fixedly connected to one side of one of the handrails 1. The outer side of the lifting plate 9 is slidably connected to the inner wall of the concave plate 5. One end of the first electric push rod 7 is fixedly connected to the bottom of the concave plate 5, and its telescopic part passes through the bottom of the concave plate 5 and is fixedly connected to the bottom of the lifting plate 9. A cover 8 is hinged to one side of the concave plate 5.

[0026] When the height of the comfort mechanism needs to be adjusted, the first electric push rod 7 is activated, and its telescopic part extends or retracts, causing the lifting plate 9 to slide and rise on the inner wall of the concave plate 5, thereby achieving height adjustment of the comfort mechanism. When the comfort mechanism is not in use, the lifting plate 9 can be lowered to the lowest position, allowing the comfort mechanism to be stored inside the concave plate 5. Then, the cover 8 can be manually closed to enclose the comfort mechanism inside. At this time, the surface of the cover 8 can be used to place items.

[0027] Example 2

[0028] refer to Figure 1-5 Improvements based on Example 1:

[0029] A bearing 13 for adjusting the blowing angle is fixedly installed on the top of the lifting plate 9. A rod is fixedly installed on the inner wall of the inner ring of the bearing 13. The bottom of the blower box 6 is fixedly connected to the top of the rod. A fixing ring 10 is fixedly sleeved on the rod. A circular hole is opened on the fixing ring 10. A plug rod 11 for fixing the blowing angle is slidably connected to the inner wall of the circular hole. Multiple insertion holes 12 are opened on the top of the lifting plate 9. The bottom end of the plug rod 11 is inserted into the insertion hole 12. The insertion holes 12 are arranged in a ring.

[0030] When the blowing angle needs to be adjusted, first pull up the insertion rod 11 by hand, so that the insertion rod 11 is away from the insertion hole 12 of the lifting plate 9. Then, manually rotate the blower box 6, which drives the rod body to rotate through the bearing 13, thereby changing the blowing angle of the blower box 6. When the blower box 6 is rotated to the appropriate angle, align the insertion rod 11 with the insertion hole 12 and insert its bottom end into the corresponding insertion hole 12, thereby fixing the blowing angle of the blower box 6.

[0031] The seat 4 has a receiving groove 20. A second electric push rod 19 for driving the footrest iron frame 15 to unfold or roll inward is fixedly installed on one inner wall of the receiving groove 20. An L plate 17 is slidably connected to the bottom inner wall of the receiving groove 20. A second hinge seat 18 is fixedly installed on one side of the top of the L plate 17. A connecting plate 16 is hinged to the second hinge seat 18. A third hinge seat is fixedly installed on the inner side of the footrest iron frame 15. One end of the connecting plate 16 is hinged to the third hinge seat.

[0032] When the footrest bracket 15 needs to be unfolded, the second electric push rod 19 is activated, its telescopic part extends, and pushes the L-plate 17 to slide on the bottom inner wall of the receiving groove 20. The movement of the L-plate 17 drives the second hinge seat 18 to move, which in turn pushes the footrest bracket 15 to rotate and unfold around the first hinge seat 14 through the connecting plate 16. When the footrest bracket 15 is unfolded to the appropriate position, the second electric push rod 19 stops working, and the footrest bracket 15 remains in the unfolded state. When the footrest bracket 15 is no longer needed, the second electric push rod 19 is activated, its telescopic part retracts, and the footrest bracket 15 rolls inward and closes on one side of the seat 4.

[0033] However, as is well known to those skilled in the art, the working principles and wiring methods of the fan, the first electric push rod 7 and the second electric push rod 19 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.
