Description

Technical Field

[0001] This application relates to the technical field of sofa cushion structure improvement, specifically to a fabric-covered edge cushion and a sofa containing the same. Background Technology

[0002] Seat cushions with encased foam padding are a common type of seat cushion structure. The internal foam padding makes the cushion softer and more comfortable, and it's often used in sofas and other furniture. Current technology typically involves wrapping the foam padding with fabric using a webbing process, and then securing the fabric edges to the seat's rigid frame with nails. However, this structure makes it inconvenient and difficult to maintain if the outer fabric needs to be removed and cleaned. Removing and washing requires tools like pliers to pry off the nails, which can easily damage the fabric. Furthermore, reassembly is often poor due to the damaged fabric, potentially leading to further tearing. Moreover, these inconveniently designed cushions are difficult to replace and maintain for personal use, and even commercial use suffers from low maintenance efficiency. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, this application provides a seat cushion with a fabric-covered edge that is easy to disassemble and clean, and whose disassembly process will not damage the fabric.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a seat cushion with fabric edging, the structure of which includes a supporting base plate, a sponge pad, and fabric; the fabric is wrapped around the outside of the sponge pad, and the supporting base plate is used to support the sponge pad after the fabric is wrapped; at least two opposite sides of the fabric are provided with edging strips, and the corresponding bottom edge of the supporting base plate is provided with a fixing strip, the fixing strip having an insertion seam, and the edging strip being folded and inserted into the insertion seam.

[0005] Using the above structure, this application achieves a detachable connection between the fabric and the supporting base plate. Specifically, after wrapping the sponge pad, the fabric has edge strips on at least two opposite sides, and a fixing strip is installed on the corresponding position on the bottom surface of the supporting base plate. Then, the two edge strips of the fabric wrapped with the sponge pad are pulled towards the fixing strip, folded over, and inserted into the joint formed by the fixing strip, thus achieving the connection between the sponge pad and the supporting base plate. This connection method does not require traditional nail fixing; the connection can be achieved simply by interlocking. When it is necessary to disassemble and clean the fabric, simply pull the edge strips out of the joint and remove the entire fabric from the sponge pad for separate cleaning. During reassembly, the edge strips are folded over and inserted into the joint again. Therefore, the entire disassembly and assembly process does not require nailing or removing nails, thus preventing damage to the fabric.

[0006] Furthermore, four edge trim strips are provided, corresponding to the four sides of the supporting base plate; four fixing strips are also provided on the supporting base plate; with this structure, after the fabric wraps around the sponge pad, edge trim strips are provided on all four sides, so that the fabric can be tightened from four directions at the same time and interlocked with the seam formed on the fixing strip to achieve interlocking connection, further improving the firmness of the connection.

[0007] Furthermore, the edge trim is sewn onto the edge of the fabric, and the edge trim is a rigid edge trim; with this structure, the fabric can be kept flat by setting the edge trim, and the rigid edge trim is not easily deformed, and the connection between it and the seam is more secure.

[0008] Furthermore, the fixing strip is fixedly connected to the bottom surface of the supporting base plate, such as by using nails or rivets to nail the fixing strip to the bottom surface of the base plate, thereby improving the firmness of the connection between the two and ensuring the stability of the edge trim strip after insertion.

[0009] Furthermore, the extension length of the fixing strip is adapted to the extension length of the edge where the supporting base plate is located; by adopting this structure, the contact area between the edge trim strip and the fixing strip can be increased, thereby improving the firmness of the connection between the two and preventing the edge trim strip from separating from the joint.

[0010] Furthermore, the fixing strip includes a connecting plate for connecting to the bottom surface of the supporting base plate, a folding plate folded relative to the connecting plate, a gap between the connecting plate and the folding plate, and an abutment plate inserted into the gap, forming the insertion seam between the abutment plate and the connecting plate. With this structure, an abutment plate is inserted into the fixing strip, and this abutment plate forms a structure that abuts against the edge strip. This method prevents the abutment force from being directly transmitted to the fixing strip body, increasing the firmness of the connection between the fixing strip and the supporting base plate. Furthermore, if the abutment plate deforms, a new abutment plate can be replaced promptly without affecting its use.

[0011] Furthermore, the connecting plate is provided with a first stop strip and a second stop strip along its length, and the corresponding abutment plate is provided with a third stop strip and a fourth stop strip; the abutment plate is inserted into the fixing strip along its length, and the first stop strip abuts against the third stop strip, and the second stop strip abuts against the fourth stop strip; with this structure, the abutment plate can be inserted into the gap formed by the connecting plate and the folding plate, and the two sets of stop strips can achieve lateral positioning of each other, thereby maintaining the stability of the relative position, and effectively inserting and fixing the edge strip into the insertion seam formed between the abutment plate and the connecting plate.

[0012] Furthermore, the inner side of the second retaining strip is an inclined surface extending towards the free end in the width direction of the connecting plate, and the fourth retaining strip is a hook-shaped retaining strip adapted to it. With this structure, the second and fourth retaining strips can be hooked together to form an abutment. After the edge strip is inserted into the joint formed between the abutment plate and the connecting plate, this hooking structure can form a fulcrum, allowing the abutment plate to rotate within a small range to form a stable abutment connection with the edge strip.

[0013] Furthermore, the connecting plate is provided with a groove, and a connector that connects to the supporting base plate is provided in the groove, and the top of the connector does not protrude from the top surface of the groove; with this structure, when the fixing strip is connected to the supporting base plate, the connector is recessed in the groove, which does not affect the flatness, so that the edge strip is inserted into the joint more smoothly.

[0014] This application also provides a sofa containing the fabric-covered and edge-finished seat cushion described above. With this type of seat cushion, the fabric covering the sponge pad can be flexibly disassembled and assembled from the supporting base without the need for nail guns or pliers to remove the nail guns, thus preventing damage to the fabric. The fabric is also more convenient and quick to remove and clean. Attached Figure Description

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only; the descriptions of front, back, top, bottom, left, and right orientations in this application refer to the position of the cushion in normal use. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular, specific embodiments and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] As attached Figure 1-13 As shown, this application discloses a fabric-covered seat cushion with edge trim. The cushion structure includes a supporting base plate 1, a sponge pad 2, and fabric 3. The fabric 3 wraps around the outside of the sponge pad 2, and the supporting base plate 1 is used to support the sponge pad 2 after the fabric 3 is wrapped. The fabric 3 has edge trim strips 301 on at least two opposite sides, and a fixing strip 101 is provided at the corresponding bottom edge of the supporting base plate 1. An insertion seam 4 is formed on the fixing strip 101, and the edge trim strip 301 is folded and inserted into the insertion seam 4. Specifically, the fabric 3 wraps around and covers the sponge pad 2, and then the edge of the fabric 3 with edge trim strip 301 is pulled to tightly wrap the sponge pad 2. The edge trim strip 301 passes over the supporting base plate 1 to its bottom position, and then the edge trim strip 301 is inserted into the insertion seam 4 formed between the fixing strip 101 and the bottom surface of the supporting base plate 3, realizing a detachable connection between the sponge pad 2, the fabric 3, and the supporting base plate 3.

[0032] Using the above structure, this application achieves a detachable connection between the fabric and the supporting base plate. Specifically, after wrapping the sponge pad, the fabric has edge strips on at least two opposite sides, and a fixing strip is installed on the corresponding position on the bottom surface of the supporting base plate. Then, the two edge strips of the fabric wrapped with the sponge pad are pulled towards the fixing strip, folded over, and inserted into the joint formed by the fixing strip, thus achieving the connection between the sponge pad and the supporting base plate. This connection method does not require traditional nail fixing; the connection can be achieved simply by interlocking. When it is necessary to disassemble and clean the fabric, simply pull the edge strips out of the joint and remove the entire fabric from the sponge pad for separate cleaning. During reassembly, the edge strips are folded over and inserted into the joint again. Therefore, the entire disassembly and assembly process does not require nailing or removing nails, thus preventing damage to the fabric.

[0033] As attached Figure 2 , 4 As shown in Figure 7, four edge trimming strips 301 are provided in this application, corresponding to the four sides of the supporting base plate 1; four fixing strips 101 are also provided on the supporting base plate 1; that is, the supporting base plate 1 of this application has a quadrilateral structure, and a fixing strip 101 is provided on the bottom surface near each of the four sides, and four edge trimming strips 301 are provided on the corresponding positions of the fabric; specifically, in order to avoid the edge trimming strips 301 being exposed, the fabric 3 can be used to completely wrap and hide the edge trimming strips 301, thereby forming a fabric surface of the same color; with this structure, after the fabric 3 wraps the sponge pad 2, edge trimming strips 301 are provided on all four sides, so that the fabric 3 can be tightened from four directions at the same time to achieve an interlocking connection with the interlocking seam 4 formed on the fixing strip 101, further improving the firmness of the connection.

[0034] As an example, the edge trim 301 described in this application is sewn onto the edge of the fabric 3, and the edge trim 301 is a rigid edge trim 301. Specifically, the edge trim 301 can be a plastic sheet or a sheet of other materials with a certain degree of rigidity, which can be sewn or glued to the edge of the fabric 3, and the fabric can completely wrap it. With this structure, the fabric 3 can be kept flat by setting the edge trim 301, making it easy to wrap the sponge pad tightly. Moreover, the rigid edge trim 301 is not easy to deform, and the connection between it and the seam 4 is more firm and tight.

[0035] As an example, the fixing strip 101 described in this application is fixedly connected to the bottom surface of the supporting base plate 1. For example, nails or rivets are used to nail the fixing strip 101 to the bottom surface of the base plate to improve the firmness of the connection between the two, thereby ensuring the stability of the edge strip 301 after insertion. The fixing strip 101 in this application is also a structure made of a rigid material, such as rigid plastic or metal.

[0036] As attached Figure 3-4 , Figure 6 , Figure 8 and Figure 10 As shown, the extension length of the fixing strip 101 described in this application is adapted to the extension length of the edge where the supporting base plate 1 is located; that is, the fixing strip 101 extends along the length of the edge corresponding to the bottom surface of the supporting base plate 1, and the two can be of equal length. By adopting this structure, the contact area between the edge trim 301 and the fixing strip 101 can be increased, thereby improving the firmness of the connection between the two and preventing the edge trim 301 from separating from the joint 4.

[0037] As attached Figure 9 , Figure 11-13As shown, the fixing strip 101 described in this application includes a connecting plate 102 for connecting to the bottom surface of the supporting base plate 1, and a folding plate 103 folded relative to the connecting plate 102 (specifically, the folding plate 103 is folded over along the tail end of the connecting plate 102 in the width direction, and after folding, a certain gap is formed between it and the connecting plate 102 in the thickness direction, and the extension width of the folding plate 103 is less than the extension width of the connecting plate 102). A gap (with an interval in the thickness direction and vertically) is provided between the connecting plate 102 and the folding plate 103. An abutment plate 5 is inserted into the gap, and the abutment plate 5 and the connecting plate... The aforementioned interlocking seam 4 is formed between 102; with this structure, an abutment plate 5 is inserted into the fixing strip 101, and then the abutment plate 5 forms a structure that interlocks and abuts with the edge strip 301. In this way, the abutment force is not directly transmitted to the body of the fixing strip 101, thereby increasing the firmness of the connection between the fixing strip 101 and the supporting base plate 1. Moreover, if the abutment plate 5 is deformed in the future, a new abutment plate 5 can be replaced in time without affecting the use; the abutment plate 5 of this application can be inserted into the fixing strip 101 from the length direction, or the two can be connected by phase change and reset from the width direction.

[0038] As attached Figure 8-9 , Figure 11-13 As shown, the connecting plate 102 of this application is provided with a first stop bar 104 and a second stop bar 105 along its length direction, and the corresponding abutment plate 5 is provided with a third stop bar 501 and a fourth stop bar 502; the abutment plate 5 is inserted into the fixing bar 101 along its length direction, and the first stop bar 104 abuts against the third stop bar 501, and the second stop bar 105 abuts against the fourth stop bar 502; specifically, on the connecting plate 102, along its width... Two protruding baffles are arranged side by side along the thickness direction in the angular direction, with a certain gap between the two baffles; two baffles are also arranged on the side surface of the abutment plate 5 opposite to the connecting plate 102; with this structure, the abutment plate 5 can be inserted into the gap formed by the connecting plate 102 and the folding plate 103, and the two sets of baffles can limit each other in the lateral direction, thereby maintaining the stability of the relative position, and effectively inserting and fixing the edge strip 301 into the insertion seam 4 formed between the abutment plate 5 and the connecting plate 102.

[0039] As attached Figure 11-13As shown, the inner side of the second retaining strip 105 described in this application is an inclined surface extending towards the free end in the width direction of the connecting plate (the inclined surface is inclined towards the direction of the first retaining strip 104), and the fourth retaining strip 502 is a hook-shaped retaining strip adapted to it; with this structure, the second retaining strip 105 and the fourth retaining strip 502 can be hooked together to form an abutment. After the edge strip 301 is inserted into the insertion seam 4 formed between the abutment plate 5 and the connecting plate 102, this hooking structure can form a fulcrum, allowing the abutment plate 5 to rotate within a small range to form a stable abutment connection with the edge strip 301.

[0040] As attached Figure 5 , Figure 8-9 , Figure 11-12 As shown, the connecting plate 102 described in this application is provided with a groove 106, and a connector 6 connected to the supporting base plate 1 is provided in the groove 106, and the top end of the connector 6 does not protrude from the top surface of the groove 106; specifically, the groove is recessed in the direction of the base plate. With this structure, when the fixing strip 101 is connected to the supporting base plate 1, the connector 6 is recessed in the groove 106, which will not affect the flatness, so that the edge strip 301 can be inserted into the joint 4 more smoothly; the connector can be a rivet, screw or other connection structure.

[0041] This application also provides a sofa containing the fabric-covered and edge-finished seat cushion described above. With this type of seat cushion, the fabric covering the sponge pad can be flexibly disassembled and assembled from the supporting base without the need for nail guns or pliers to remove the nail guns, thus preventing damage to the fabric. The fabric is also more convenient and quick to remove and clean.

[0042] The fabric-covered seat cushion described in this application features a fixing strip on the support base plate and a corresponding edge strip on the fabric. The edge strip and the fixing strip are detachably connected, achieving a detachable connection between the fabric-covered seat cushion and the support base plate. This eliminates the need for the traditional method of fixing the fabric to the support base plate with nails, avoiding damage to the components and eliminating the need for pliers to remove the nails. This structure simply requires inserting the edge strip on the fabric into the fixing strip; when replacing, simply remove the fixing strip, clean and maintain it, and then insert it back in.
