Description

Technical Field

[0001] The utility model relates to the technical field of sofa cushions, in particular to a detachable and replaceable sofa cushion. Background Art

[0002] Sofa cushions are soft cushions used to cover the seat and back of a sofa. They are usually made of soft fabric and filling, providing extra comfort and support. They not only protect the sofa from wear and tear, but also add to the beauty of the interior decoration. Sofa cushions are easy to replace and wash, which helps to improve the comfort and practicality of the home environment.

[0003] There are generally three types of sofa cushions in the prior art. The first type of sofa cushion includes an outer cover and a filler therein, and this type of sofa cushion is directly placed on a sofa for use. The second type of sofa cushion includes an outer cover, a filler therein, and a drawstring. When in use, this type of sofa cushion is also directly placed on the sofa, but is bound to the sofa by a drawstring, so that the sofa cushion is not easy to fall off the sofa. The third type of sofa cushion includes an outer cover and a filler therein, and this type of sofa cushion is usually placed on a wooden sofa. Its thickness is greater than that of the first two types of sofa cushions, and it mainly plays a supporting role.

[0004] The three types of sofa cushions in the prior art all have defects to some extent. When the first type of sofa cushion is placed on a sofa, due to the small friction between the sofa and the sofa, when a user sits on it, the user will inevitably not sit upright. Once the user maintains a posture other than sitting upright, or applies an outward friction force to the sofa cushion, and the friction force is greater than the friction force between the sofa cushion and the sofa, the sofa cushion will be displaced on the sofa or even fall off the sofa.

[0005] The second type of sofa cushion is based on the first type of sofa cushion and has a drawstring structure added to prevent the sofa cushion from falling off the sofa. However, the positioning of the sofa cushion has nothing to do with the tightness of the drawstring. Whether the drawstring is loose or tight, the drawstring has a certain elasticity and cannot completely position the sofa cushion. The sofa cushion will still deviate or wrinkle on the sofa within a certain range. For users sitting, the displacement or wrinkling of the sofa cushion will cause discomfort.

[0006] The third type of sofa cushion will not have the problems of deviation, falling and wrinkling that exist in the first two types of sofa cushions. However, once the sofa cushion is dirty, the outer cover of the sofa cushion needs to be removed for cleaning. After cleaning and drying, it can be re-installed on the outside of the filling. Since the sofa cushion is used on a wooden sofa for user support and comfort, the natural volume of the filling is often kept larger than the volume of the outer cover. The filling ensures that the outer cover is expanded to a tighter state. Therefore, when removing the outer cover and assembling the entire sofa cushion, the user actually needs to spend a lot of effort to complete the operation.

[0007] In summary, several conventional sofa cushions currently on the market all have their own problems and cannot fully meet the needs of users.

[0008] Therefore, a detachable and replaceable sofa cushion is proposed to solve or alleviate the above problems. Utility Model Content

[0009] The utility model aims to solve the shortcomings of the prior art and provides a detachable and replaceable sofa cushion.

[0010] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Preferably, there is a distance between the detachable connection between the replacement pad and the base pad and the edge of the bottom surface of the replacement pad.

[0013] Preferably, the thickness of the base pad is gradually reduced from its center to the surrounding areas, and the thickness of the replacement pad is uniformly set in its unfolding direction.

[0014] Preferably, the top surface of the base pad is fixedly connected to a lower connecting surface layer, the bottom surface of the replacement pad is fixedly connected to an upper connecting surface layer, and the base pad and the replacement pad are detachably connected via the lower connecting surface layer and the upper connecting surface layer.

[0015] Preferably, an upper fluff layer is arranged on the lower connecting surface layer, a lower fluff layer is arranged on the upper connecting surface, the hardness of the lower fluff layer is greater than that of the upper fluff layer, and hooks are present on the fluff in the lower fluff layer.

[0016] Preferably, the base pad includes an outer shell and a filler filled therein, and the lower connecting surface layer is fixedly connected to the top surface of the outer shell.

[0017] Preferably, the filler includes one or more of cotton, spray-bonded cotton, imitation silk cotton, sponge, memory foam, latex, wool, and down.

[0018] Preferably, the replacement pad comprises a fabric layer, and the upper connecting surface layer is fixedly connected to the bottom surface of the fabric layer.

[0019] Preferably, the fabric layer can be made of one or more of linen fabric, canvas, denim, cotton and linen blended fabric, and Oxford fabric.

[0020] The utility model has the following beneficial effects:

[0021] When the utility model is actually applied, it is directly applied to a wooden sofa as a supporting and buffering structure. Due to its heavy structure, it is not easy to fall off the wooden sofa. It can be stuck in the sofa through the outward expansion and elasticity of the bottom pad. If the surface of the bottom pad is dirty, the replacement pad can be directly removed for replacement and cleaning. After replacement and installation, the replacement pad and the bottom pad are kept in a surface connection state. Therefore, when the replacement pad provides friction when the user sits, the replacement pad is not easy to fall off from the bottom pad. Even if the user changes the sitting posture on the replacement pad, the replacement pad is not easy to deviate or wrinkle on the bottom pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In the description of the present utility model, it should be understood that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the utility model product is conventionally placed when in use, or are the orientations or positional relationships conventionally understood by those skilled in the art. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present utility model.

[0030] Furthermore, the terms “first”, “second”, “third”, etc. are merely used for distinguishing descriptions and are not to be understood as indicating or implying relative importance.

[0031] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] A removable replacement sofa cushion, such as Figure 1 As shown, it includes a base pad 1 and a replacement pad 2, the thickness of the base pad 1 is greater than the thickness of the replacement pad 2, the replacement pad 2 is detachably connected to the top surface of the base pad 1, the detachable connection between the replacement pad 2 and the base pad 1 is a surface connection, and the area of ​​the detachable connection between the replacement pad 2 and the base pad 1 is smaller than the projection area of ​​the replacement pad 2.

[0033] The structural setting of the replacement pad 2 and the bottom pad 1 is that the bottom pad 1 is used as the bottom layer of the foundation, and the replacement pad 2 is used as the side in contact with the user. The detachable connection between the replacement pad 2 and the bottom pad 1 is a surface connection, which can ensure that the two have a certain connection strength when connected, and when the user sits on the replacement pad 2 and changes posture, thereby bringing uneven friction to the replacement pad 2, the replacement pad 2 and the bottom pad 1 can also resist through the surface connection between the two, thereby avoiding the main connection position of the replacement pad 2 and the bottom pad 1 on the bottom pad 1 to be offset or wrinkled, and because the area of ​​the detachable connection between the replacement pad 2 and the bottom pad 1 is smaller than the projection area of ​​the replacement pad 2, it is convenient for the user to replace the replacement pad 2 when he needs to, and lift up the replacement pad 2 through the difference between the two areas, and then disassemble and replace it. On the whole, such a structural setting makes the entire sofa cushion easy to disassemble, clean and assemble later, and can also prevent the sofa cushion from falling off the sofa, and can avoid the replacement pad 2 from wrinkling or offsetting at the main sitting position on the bottom pad 1 due to the user's sitting posture.

[0034] As for the action of replacing the replacement pad 2 on the base pad 1, its main purpose is to replace the replacement pad 2 when it is dirty or damaged. At this time, the replacement pad 2 needs to be washed or even replaced with a new one to ensure that the replacement pad 2 set on the base pad 1 is always kept clean and tidy. In addition, the replacement pad 2 can also be replaced according to the change of seasons, that is, when the weather is cold, the replacement pad 2 is required to have a certain warmth-keeping effect, and when the weather is hot, the replacement pad 2 is required to have a certain cool feeling when touched. How to specifically reflect the warmth-keeping performance or cool feeling is reflected by the material of the replacement pad 2. For example, when the weather is cold, the replacement pad 2 can be made of cotton or a layer of fleece can be formed on the top surface of the replacement pad 2 by sanding or flocking, so that the replacement pad 2 has a better warmth-keeping effect. For example, when the weather is hot, the replacement pad 2 is made of polyester, and its surface is flat, smooth and hairless. The cool feeling of the polyester material itself makes the replacement pad 2 also have a cool feeling.

[0035] Preferably, there is a gap between the detachable connection between the replacement pad 2 and the base pad 1 and the bottom edge of the replacement pad 2 .

[0036] There is a spacing between the detachable connection between the replacement pad 2 and the base pad 1 and the bottom edge of the replacement pad 2, and the actual area of ​​the detachable connection between the replacement pad 2 and the base pad 1 is smaller than the projected area of ​​the replacement pad 2. It should be noted that the spacing is set equidistantly, so that a position for the user to grab the replacement pad 2 can be formed between the detachable connection between the replacement pad 2 and the base pad 1 and the bottom edge of the replacement pad 2, and the spacing at this position is uniform, so that the replacement pad 2 will not be severely warped locally on the base pad 1, and the replacement pad 2 can be spread out on the base pad 1 relatively evenly.

[0037] Preferably, the thickness of the base pad 1 is gradually reduced from its center to the surroundings, and the thickness of the replacement pad 2 is uniformly set in its unfolding direction.

[0038] The bottom cushion 1 is high in the middle and low around, so that when the bottom cushion 1 is embedded in the sofa, it can be normally stuck in the sofa through its fluffy and elastic structure when no one is sitting on it, so as to prevent the sofa cushion from falling out of the sofa. If the user sits on the sofa cushion, the sofa cushion will be subjected to top-down pressure at its center position, and the sofa cushion will undergo relative elastic deformation. While it becomes flat, its cross-sectional area will also become relatively larger, and the bottom cushion 1 will expand outward, so that it is stuck in the sofa more firmly, and the sofa cushion can be fixed in the sofa without adding an additional fixing structure.

[0039] Preferably, the top surface of the base pad 1 is fixedly connected to a lower connecting surface layer 102, and the bottom surface of the replacement pad 2 is fixedly connected to an upper connecting surface layer, and the base pad 1 and the replacement pad 2 are detachably connected via the lower connecting surface layer 102 and the upper connecting surface layer.

[0040] By setting the upper connecting surface layer and the lower connecting surface layer 102 as the connecting structure of the replacement pad 2 and the base pad 1, the surface connection between the two is achieved. When producing sofa cushions, it is only necessary to install the lower connecting surface layer 102 and the upper connecting surface layer on the base pad 1 and the replacement pad 2 respectively by fixing methods such as bonding or sewing, which is convenient for processing.

[0041] Preferably, an upper fluff layer is arranged on the lower connecting surface layer 102, and a lower fluff layer is arranged on the upper connecting surface. The hardness of the lower fluff layer is greater than that of the upper fluff layer, and hooks are present on the fluff in the lower fluff layer.

[0042] The fluff on the upper and lower fluff layers can be made by sanding or flocking, wherein the fluff on the upper fluff layer needs to be a softer fiber, such as polyester, and the fluff on the lower fluff layer needs to be a harder fiber, such as nylon. The fluff on the lower fluff layer is curled to form a hook after heat treatment, and the fluff in the upper fluff layer can form a loop-like structure. When the upper fluff layer on the lower connecting surface layer 102 is connected with the lower fluff layer on the upper connecting surface, the fluff in the lower fluff layer enters the loop of the fluff in the upper fluff layer with the hook for connection, achieving a structure similar to the hook surface and the fleece surface of Velcro, thereby realizing the detachable connection between the replacement pad 2 and the base pad 1, and the connection strength of the structure is affected by the material, which is weaker than the ordinary Velcro connection strength, and is also convenient for subsequent users to replace and disassemble the replacement pad 2.

[0043] Preferably, if Figure 2As shown, the base pad 1 includes an outer shell 101 and a filler filled therein, and a lower connecting surface layer 102 is fixedly connected to the top surface of the outer shell 101 .

[0044] The outer cover 101 and the filler constitute the most basic structure of the base pad 1, and the shape of the outer cover 101 is formed by the sewing process. At the same time, with the filling of the filler, the base pad 1 can maintain a state in which the thickness of the base pad 1 gradually decreases from its center position to the surroundings.

[0045] Preferably, the filling material comprises one or more of cotton, spray-bonded cotton, imitation silk cotton, sponge, memory foam, latex, wool and down.

[0046] Cotton, spray-bonded cotton, imitation silk cotton, sponge, memory foam, latex, wool, and down can all provide a certain degree of elasticity, support performance, and fluffiness, and can be directly filled into the jacket 101. In the specific implementation process, other suitable materials can also be selected as fillers according to needs.

[0047] Preferably, the replacement pad 2 comprises a fabric layer, and the upper connecting surface layer is fixedly connected to the bottom surface of the fabric layer.

[0048] Preferably, the fabric layer can be made of one or more of linen fabric, canvas, denim, cotton and linen blended fabric, and Oxford fabric.

[0049] The material of the fabric layer can be selected according to the needs. The fabric layer is mainly used as the object in direct contact with the user, and has certain wear resistance and good comfortable feel.

[0050] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
