Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a sofa that does not require the installation of legs. Background Technology

[0002] Sofas, as common pieces of furniture, typically have support legs under the seating area to elevate it and maintain a certain distance from the ground. This design not only makes the sofa appear lighter and more aesthetically pleasing, but more importantly, it facilitates cleaning the floor space beneath the sofa, preventing hard-to-reach areas from becoming unsanitary.

[0003] However, this conventional design presents significant problems in the packaging and transportation of sofas. Fixed support legs substantially increase the overall volume and height of the packaged product, leading to low space utilization during transport and increased warehousing and logistics costs. To address this issue, the common practice is to design detachable support legs. During factory packaging, the support legs are removed and packaged separately from the sofa body. Upon arrival at the customer's home, the legs are then assembled on-site by an installer or the user.

[0004] However, this detachable design also has significant drawbacks. First, it adds the after-sales installation step, requiring professional on-site service or user self-assembly. This not only increases labor and time costs but also introduces risks due to lost parts or improper installation. Second, the separate support legs pose a risk of management difficulties and loss during distribution.

[0005] Therefore, it is necessary to improve the existing sofa's support structure to balance the convenience of transportation and ease of use.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a sofa that does not require the assembly of legs, which can effectively solve the problems of cumbersome assembly of support legs and easy loss of parts in existing sofas.

[0008] To achieve the above objectives, this utility model provides a sofa that does not require additional legs, comprising:

[0009] The sofa body has a downward-facing receiving groove at its bottom;

[0010] At least two rotatable legs are rotatably mounted in the receiving groove about a horizontal axis;

[0011] The rotating support leg has an inwardly retracted state where it rotates inward to be fully housed in the receiving groove; and an outwardly retracted state where it rotates outward to extend out of the receiving groove and abut against the bottom surface of the sofa body.

[0012] Optionally, the accommodating groove has a rotating shaft mounting hole extending along the horizontal axis in its groove wall.

[0013] The rotating support leg has a transverse shaft hole corresponding to the position of the rotating shaft mounting hole.

[0014] The sofa without legs also includes a horizontal pivot, which passes through the horizontal pivot hole and is threadedly connected to the pivot mounting hole.

[0015] Optionally, the transverse rotating shaft includes a smooth rod portion rotatably connected to the transverse shaft hole, and a screw portion threadedly connected to the rotating shaft mounting hole.

[0016] Optionally, the rotating support includes:

[0017] A rotating shaft connecting plate, one end of which is provided with the transverse shaft hole;

[0018] A first support plate is fixedly connected to the other end of the rotating shaft connecting plate;

[0019] The second support plate is fixedly connected to the middle position of the rotating shaft connecting plate;

[0020] When the rotating leg is in the outward-folding state, the second support plate is located below the sofa body and abuts against the sofa body upward.

[0021] Optionally, both the first support plate and the second support plate include a transverse portion disposed opposite to the pivot connecting plate, and a longitudinal portion connecting the transverse portion to the pivot connecting plate.

[0022] Optionally, the bottom of the receiving groove is provided with a magnetic suction element that is magnetically connected to the first support plate at the position corresponding to the first support plate, so as to restrict the rotating leg from rotating outward.

[0023] Optionally, the difference between the distance a from the transverse shaft hole to the second support plate and the distance b from the shaft mounting hole to the opening of the receiving groove is less than 20 mm.

[0024] Optionally, the distance a from the transverse shaft hole to the second support plate is equal to the distance b from the shaft mounting hole to the opening of the receiving groove.

[0025] Optionally, the rotating support leg further includes:

[0026] An adjustable support pad is located on the side of the second support plate away from the first support plate;

[0027] An adjustment knob, which is threaded through the second support plate from the side of the second support plate near the first support plate and connected to the bottom of the adjustable support pad, is used to adjust the distance between the adjustable support pad and the second support plate.

[0028] Optionally, the rotating shaft connecting plate, the first support plate, and the second support plate are integrally formed components.

[0029] The beneficial effects of this utility model are as follows: It provides a sofa that requires no additional legs. During transportation or storage, the rotating legs of the sofa are in an inward-rotating state, fully retracted into the receiving slot. At this time, the rotating legs are hidden at the bottom of the sofa body, without increasing the overall height and volume of the sofa, facilitating compact packaging. When the sofa arrives at its location, the user does not need any tools or additional installation steps; they simply manually rotate the rotating legs outward around the horizontal axis, causing them to extend from the receiving slot until they reach an outward-folding state. In this outward-folding state, the rotating legs extend from the receiving slot and abut against the bottom surface of the sofa body, thereby stably supporting the sofa body and maintaining a certain distance between the sofa and the ground.

[0030] In the above process, users do not need to assemble the legs on-site, simplifying the usage process and avoiding problems caused by lost parts or incorrect installation. Therefore, the leg-free sofa provided by this utility model can effectively solve the problems of troublesome leg assembly and easy loss of parts in existing sofas. Attached Figure Description

[0047] See Figures 1-3 This utility model provides a sofa that does not require the installation of legs, comprising:

[0048] The sofa body 1 has a downward-facing receiving groove 101 at its bottom;

[0049] At least two rotating legs 2 are rotatably mounted in the receiving groove 101 about a horizontal axis;

[0050] The rotating support 2 has an inwardly retracted state where it rotates inward and is completely housed in the receiving groove 101 (e.g., Figure 1 (as shown); and has an outwardly rotated state that extends outward from the receiving groove 101 and abuts against the bottom surface of the sofa body 1 (as shown). Figure 2(As shown).

[0051] During transportation or storage, the rotating legs 2 of the sofa, which requires no additional installation, are in a retracted state, fully retracted into the receiving groove 101. In this state, the rotating legs 2 are hidden at the bottom of the sofa body 1, without increasing the overall height or volume of the sofa, facilitating compact packaging. Once the sofa arrives at its location, the user requires no tools or additional installation steps; simply manually rotate the rotating legs 2 outwards around the horizontal axis, extending them from the receiving groove 101 until they are flipped outwards. In this flipped-out state, the rotating legs 2 extend from the receiving groove 101 and abut against the bottom surface of the sofa body 1, thus stably supporting the sofa body 1 and maintaining a certain distance between the sofa and the ground.

[0052] The sofa without legs provided in this embodiment has the following advantages:

[0053] ① No installation required: Users do not need to assemble the legs on site, which simplifies the usage process and avoids problems caused by missing parts or incorrect installation.

[0054] ② Saves transportation space: In the retracted state, the rotating support 2 is fully embedded in the receiving groove 101, which significantly reduces the packaging volume of the sofa, improves transportation and storage efficiency, and reduces costs.

[0055] ③ Easy to use: The leg mode can be switched quickly and easily. Simply rotate the leg to switch between storage and support functions, which improves the user experience.

[0056] ④ Structural integration: The legs and sofa body are integrated into one unit, avoiding the management problems of separate parts and reducing after-sales maintenance needs.

[0057] Therefore, the sofa with no need to assemble the support legs provided by this utility model can effectively solve the problems of troublesome assembly of support legs and easy loss of parts in existing sofas.

[0058] In this embodiment, the groove wall of the receiving groove 101 is provided with a pivot mounting hole 102 extending along the horizontal axis; the rotating leg 2 is provided with a transverse shaft hole 2021 corresponding to the position of the pivot mounting hole 102; the sofa without legs also includes a transverse pivot 3, which passes through the transverse pivot hole 2021 and is threadedly connected to the pivot mounting hole 102.

[0059] When installing the rotating leg 2, the transverse rotating shaft 3 passes through the transverse shaft hole 2021 on the rotating leg 2 and is then threadedly connected to the rotating shaft mounting hole 102 on the wall of the receiving groove 101. In this way, the rotating leg 2 is rotatably mounted in the receiving groove 101 via the transverse rotating shaft 3. When the rotating leg 2 rotates about the horizontal axis, the transverse rotating shaft 3 rotates relative to it within the transverse shaft hole 2021, allowing the leg to be retracted or folded outwards.

[0060] Furthermore, the transverse rotating shaft 3 includes a smooth rod portion rotatably connected to the transverse shaft hole 2021, and a screw portion threadedly connected to the rotating shaft mounting hole 102.

[0061] The smooth rod portion of the transverse rotating shaft 3 is rotatably engaged with the transverse shaft hole 2021, allowing the rotating support leg 2 to rotate freely; while the screw portion is threadedly connected to the rotating shaft mounting hole 102, securing the transverse rotating shaft 3 to the receiving groove 101. When the rotating support leg 2 rotates, the smooth rod portion reduces friction, ensuring rotational flexibility.

[0062] In this embodiment, the rotating support 2 includes:

[0063] A rotating shaft connecting plate 202, one end of which is provided with the transverse shaft hole 2021;

[0064] The first support plate 201a is fixedly connected to the other end of the rotating shaft connecting plate 202;

[0065] The second support plate 201b is fixedly connected to the middle position of the rotating shaft connecting plate 202;

[0066] When the rotating support leg 2 is in the outward-folding state, the second support plate 201b is located below the sofa body 1 and abuts against the sofa body 1 upwards, providing primary support; simultaneously, the first support plate 201a contacts the ground, forming a stable support base. The pivot connecting plate 202 serves as a connecting component, ensuring that the relative positions of the first support plate 201a and the second support plate 201b remain stable.

[0067] Furthermore, both the first support plate 201a and the second support plate 201b include a transverse portion 2011 disposed opposite to the pivot connecting plate 202, and a longitudinal portion 2012 connecting the transverse portion 2011 to the pivot connecting plate 202.

[0068] The support height (ground clearance) of the sofa body 1 is mainly determined by the relative position and distance between the first support plate 201a and the second support plate 201b. The length of the longitudinal portion 2012 mainly affects the relative distance between the transverse portion 2011 of the rotating leg 2 and the opening of the receiving groove 101 when it is in the outward flipped state. For example, the longer the longitudinal portion 2012, the farther the distance from the transverse portion 2011 to the opening of the receiving groove 101 after flipping outward; conversely, the shorter the longitudinal portion 2012, the closer the distance from the transverse portion 2011 to the opening of the receiving groove 101 after flipping outward.

[0069] By adjusting the length of the longitudinal section 2012, the final position of the rotating leg 2 after it flips outward can be controlled, ensuring its compatibility with the structure of the sofa body 1 and its overall aesthetics. Precisely designing the length of the longitudinal section 2012 can prevent the rotating leg 2 from interfering with the groove of the receiving slot 101 or other structures during rotation.

[0070] Optionally, the bottom of the receiving groove 101, corresponding to the position of the first support plate 201a, is provided with a magnetic suction element that magnetically connects to the first support plate 201a to restrict the outward rotation of the rotating leg 2. When the rotating leg 2 rotates inward to the retracted state, the first support plate 201a is located above the second support plate 201b and rotates to be directly opposite the magnetic suction element. The magnetic suction element and the first support plate 201a are magnetically connected, generating an attraction force, thereby restricting the rotating leg 2 from accidentally rotating outward due to its own weight or transportation vibration. When it is necessary to unfold the leg, the user needs to apply a certain torque to overcome the magnetic attraction force and make the rotating leg 2 rotate outward.

[0071] In this embodiment, the difference between the distance 'a' from the transverse shaft hole 2021 to the second support plate 201b and the distance 'b' from the pivot mounting hole 102 to the opening of the receiving groove 101 plays a crucial role. If 'a' is much greater than 'b', when rotated to the outward-folding state, the entire rotating leg 2 is tilted relative to the sofa body 1, and the second support plate 201b cannot properly fit against the bottom surface of the sofa body 1. Conversely, if 'a' is much greater than 'b', when rotated to the outward-folding state, the longitudinal portion 2012 of the second support plate 201b will first abut against the edge of the opening of the receiving groove 101, and the transverse portion 2011 of the second support plate 201b will not contact the bottom surface of the sofa body 1.

[0072] By controlling the difference, the second support plate 201b can horizontally abut against the bottom surface of the sofa when it is folded outwards. In this embodiment, the difference between the distance dimension a (the distance from the transverse shaft hole 2021 to the second support plate 201b) and the distance dimension b (the distance from the pivot mounting hole 102 to the opening of the receiving groove 101) is less than 20mm. This ensures that when the rotating leg 2 is folded outwards, the second support plate 201b can smoothly conform to the bottom surface of the sofa body 1.

[0073] Furthermore, the distance 'a' from the transverse shaft hole 2021 to the second support plate 201b is equal to the distance 'b' from the pivot mounting hole 102 to the opening of the receiving groove 101. When distance 'a' equals distance 'b', the rotating leg 2 rotates to the outward-folding state, and the second support plate 201b is precisely horizontally abutting against the bottom surface of the sofa body 1, without tilting or interference. This equidistant design ensures that the transverse portion 2011 of the second support plate 201b is completely parallel to the bottom surface of the sofa, achieving maximum contact area.

[0074] In this embodiment, the rotating support 2 further includes:

[0075] Adjustable support pad 203, the adjustable support pad 203 is located on the side of the second support plate 201b away from the first support plate 201a;

[0076] An adjustment knob 204 is threaded through the second support plate 201b from the side of the second support plate 201b near the first support plate 201a and connected to the bottom of the adjustable support pad 203. The adjustment knob 204 is used to adjust the distance between the adjustable support pad 203 and the second support plate 201b.

[0077] When the rotating support leg 2 is in the outward-folding position, if there is a gap or incomplete fit between the bottom surface of the sofa body 1 and the first support plate 201a, the user can adjust the distance between the adjustable support pad 203 and the second support plate 201b by rotating the adjustment knob 204, causing the threaded part of the adjustment knob 204 to move on the second support plate 201b. The upward movement of the adjustable support pad 203 can compensate for the gap, ensuring that the second support plate 201b is tightly against the bottom surface of the sofa.

[0078] Optionally, the rotating shaft connecting plate 202, the first support plate 201a, and the second support plate 201b are integrally formed components, such as through die casting. Integral components have high structural strength and require no additional assembly. This makes the rotating support leg 2 structurally robust, allowing it to be directly connected to the transverse rotating shaft 3 as a single component during installation.

[0079] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
