Description

Technical Field

[0001] The present invention relates to the technical field of mattresses, and particularly to a mattress with a sheet fixing structure including a flexible connection. Background Art

[0002] Mattresses belong to large furniture products, and in terms of appearance, they need to be regular and integral. It is necessary to avoid as much as possible the presence of components with commonly used functions that can be completely detached in their structure. Although the sheet fixer accounts for a very small proportion in the structure of the whole mattress, preventing the loss of any of its components is given a very high weight in the production and manufacturing of mattresses because the loss of the components of the sheet fixer not only causes trouble in use but also damages the value of the whole mattress due to the loss of a small component.

[0003] Sheet fixers can generally be divided into three types from the perspective of whether they can be separated:

[0004] 1. Those that can be completely separated from the mattress, such as "Sheet Fixer CN209661027U", "A New Type of Sheet Fixer CN216454241U", "Sheet Fixer CN216723908U", etc. The sheet fixer can be detached and completely separated from the mattress.

[0005] 2. Those where part is pressed by the mattress or part is connected to the bed frame, while another part can be completely separated from the mattress or the bed frame, such as "Sheet Fixer CN213909386U", "A Fixing Device for Sheets CN215226532U", "A Multifunctional Fixer CN218127778U", etc. The component (i.e., the operating part) of the sheet fixer used to operate and fix the sheet can be detached and completely separated from the mattress or the bed frame.

[0006] 3. Those that are connected to the mattress or the bed frame and cannot or are not separated from the mattress or the bed frame, such as "A Clamp and Hook Member CN105520427B", "A Mattress Capable of Fixing a Bedspread CN108283403A", "A Sheet Clamping Device and a Bed Frame CN114886265B", etc. The sheet fixer is connected to the mattress or the bed frame, and the sheet fixer needs to maintain a complete connection with the mattress or the bed frame to be used normally.

[0007] The first type of sheet fixer and the second type of sheet fixer are often configured by consumers themselves and are the most common because in the current reality, mattresses with a built-in sheet fixing function are relatively rare, and sheet fixing is more often solved by consumers themselves. However, whether it can be completely separated or partially separated, being separable means that it is easy to cause the loss of its components, which is troublesome to find. Among them, the first type of sheet fixer that can be completely separated from the mattress also requires re-distributing and positioning multiple sheet fixers every time the sheet is fixed, which is quite time-consuming.

[0008] The second type of sheet fastener often requires an extension connection part in addition to the key device that contacts and connects the sheet. One end (or a certain part) of the extension connection part is used for fixation (i.e., for connecting to the mattress, for connecting to the components pressed under the mattress, for connecting to the bed frame, etc.), and the other end of the extension connection part is the device that contacts and connects the sheet it carries.

[0009] Taking "a fixing device for a sheet CN215226532U" as an example for analysis, a detachable fixing cover plate (i.e., the operating part) is installed on the fixing piece (i.e., the fixing part). The fixing piece (i.e., the fixing part) is also connected with a pressing plate through a connecting cloth belt (i.e., a flat belt), and the pressing plate presses on the bottom of the mattress during use. That is, the fixing cover plate (i.e., the operating part) cooperates with the fixing piece (i.e., the fixing part) to connect the sheet. The fixing cover plate (i.e., the operating part) does not remain connected to the fixing piece (i.e., the fixing part), which easily causes the loss of the fixing cover plate (i.e., the operating part). Although there is a connecting cloth belt (i.e., a flat belt) in its structure, the connecting cloth belt (i.e., a flat belt) does not contact and connect with the fixing cover plate (i.e., the operating part). The use of the connecting cloth belt (i.e., a flat belt) is to place it between the fixing piece (i.e., the fixing part) and the pressing plate to connect the two, resulting in a relatively large and cumbersome overall structure and poor usability, and it requires both hands to hold and operate.

[0010] Of course, since the second type of sheet fastener, like the first type, is sold and used as a scattered device, connecting the fixing cover plate (i.e., the operating part) to the fixing piece (i.e., the fixing part) will be regarded as unnecessary and will also reduce the operational usability of the fixing cover plate (i.e., the operating part). After all, the range of movement of the fixing cover plate (i.e., the operating part) will be restricted to a certain extent after connection. In addition, connecting the fixing cover plate (i.e., the operating part) to the fixing piece (i.e., the fixing part) will also change the form in which the sheet is fixed, and the fixing cover plate (i.e., the operating part) will be covered by the sheet. So, if we consider preventing the loss of components, should we connect the fixing cover plate (i.e., the operating part) to the fixing piece (i.e., the fixing part) to avoid the loss of the fixing cover plate (i.e., the operating part) after it is disassembled and taken away? In reality, the weight of preventing component loss considered in this type of sheet fastener used as a scattered device is almost zero, because we will not connect the fixing cover plate (i.e., the operating part) to the fixing piece (i.e., the fixing part) due to the possible factor of component loss, thereby sacrificing the relative flexibility that the fixing cover plate (i.e., the operating part) should have when used as a scattered device. Also, because the loss of a component of this kind of non-high-value and non-scarce scattered device does not cause much damage.

[0011] As a scattered device sold and used, the operating part of the second type of sheet fastener for operating and fixing the sheet can be completely disassembled and taken away, which is a common product model and there is no fundamental need to connect the operating part to the fixing part.

[0012] Although webbing is often used in the art, as described above, in traditional sheet fasteners that include webbing, the webbing is generally a relatively long strip. One end (or a certain part) of the webbing is used for fixation (i.e., for connecting to the mattress, for connecting to components pressed under the mattress, for connecting to the bed frame, etc.); the other end of the webbing is a movable part with a device for contacting and connecting the sheet in a clamping manner, and is connected to the sheet relatively far from the end (or a certain part) of the webbing used for fixation.

[0013] The purpose of the webbing in the traditional technology is to be placed between the device for contacting and connecting the sheet, the mattress, and / or an object adjacent to the mattress to connect these two or more of them, and the overall structure of the formed sheet fastener is large and cumbersome.

[0014] The third type of sheet fastener is more appropriate and convenient to use compared with the other two types. And it is more appropriate to install the sheet fastener on the mattress than on the bed frame. To avoid possible loss of components, it is required that the sheet fastener installed on the mattress does not have components that can be detached from the mattress. Although traditional mattresses equipped with sheet fasteners generally meet the aforementioned anti-loss requirements and do not have components that can be detached from the mattress, the structure of the sheet fixing device therein is generally relatively complex and bulky, and the operation flexibility and ease of use are poor; or the strips in the sheet fastener are relatively long, and it is very cumbersome to connect multiple strips to the mattress, which is not beautiful and troublesome to use.

[0015] Such as "a mattress capable of fixing a bedspread CN108283403A", its sheet fixing device is composed of a mounting plate, a fixing plate, a connecting shaft, an elastic component, a mounting ring, a vertical rod, a limiting plate, and an anti-slip rubber, with a complex and bulky structure and difficult to be actually applied.

[0016] Such as "a non-slip mattress CN202069254U", multiple connecting bands are distributed and connected on the vertical surface of the mattress. The operation of fixing or unfastening the sheet requires both hands to hold, which is very cumbersome, not beautiful and troublesome to use.

[0017] Such as "a fixture and hook member CN105520427B", its push-pull movable member (i.e., the operation part) is connected to the fixed base (i.e., the fixed part) in cooperation to connect the sheet. During the cooperation, the push-pull movable member (i.e., the operation part) moves in the up and down direction relative to the fixed base (i.e., the fixed part). The push-pull movable member (i.e., the operation part) is directly movably connected to the fixed base (i.e., the fixed part) and thus maintains the connection to the fixed base (i.e., the fixed part), forming a complex overall structure and poor ease of use (requiring relatively high operation actions. When operating to fix the sheet, two fingers need to be used to lean against the push-pull movable member in a specific "V" shape and push upward from the bottom); this complex structure also makes it impossible to have a relatively large smooth surface for making LOGO or other graphics on it.

[0018] The key device in the sheet fastener that contacts and connects the sheet usually requires the cooperation of two components to connect the sheet. To prevent loss, these two components must remain connected. When the cooperation of these two components requires one of the two components to move up and down relative to the other, if only directly connected based on these two components, the structural setting will become relatively complex, and the operation flexibility and ease of use for fixing the sheet will be poor.

[0019] Moreover, some mattresses are relatively thick and have high soft elasticity. For the sheet fastener installed on the vertical surface of the mattress, the device that contacts and connects the sheet should have room for elastic expansion and contraction up and down. Otherwise, it may cause the sheet to be overly tightened and torn when a person lies on the mattress, and may even damage the surface layer of the vertical surface of the mattress. To address this situation, if the solution of connecting one end of an elastic elastic band to the mattress and the other end to the sheet is adopted, it will be too cumbersome and troublesome to operate. A more appropriate solution is to use a sheet fastener with a moving part, which can be adjustably connected to the sheet or elastically expandably connected to the sheet through the moving part. And a sheet fastener with a moving part necessarily has a moving limit structure to allow the moving part to move along the moving limit structure. For example, the guide rail in "A Sheet Clamping Device and a Bed Frame CN114886265B" belongs to one type of moving limit structure.

[0020] The mattress is a soft furniture, and it is not suitable to set a hard structure with no elastic in the height direction on the vertical surface of the mattress. Therefore, it is more appropriate to adopt the method of elastically expandably connecting the sheet with the moving part, that is, in the sheet fastener with a moving part, the movement of the moving part is elastically constrained, and the moving part can move elastically and expandably. Based on the anti-loss requirement, the components of the sheet fastener installed on the mattress should be connected as a whole, and it is also necessary to be as integrated with the mattress as possible in appearance. Otherwise, it will affect the beauty of the mattress. However, the moving limit structure for the movement of the moving part is a basic structure. If this basic structure is exposed, it will look very obtrusive, and the sheet fastener will not be integrated with the mattress in appearance.

[0021] In response to the above situation, if the moving limit structure is completely covered by rigid plates, the resulting structure will be relatively complex and large. For example, on the premise that the operating part and the fixed part remain connected, the fixed part is provided with a travel opening and a movable part that can move up and down is installed in the travel opening. Here, the operating part is the rigid plate, the travel opening is the moving limit structure, and the operating part is connected to the movable part to fix the bedsheet. When the bedsheet is not laid on the mattress (such as when the mattress is on display in a store), if there is no structural component on the mattress to cover the moving limit structure, that is, the travel opening, then the travel opening will be exposed. The mattress product itself is an integral formed by covering a series of structural materials, and generally, the exposure of the basic structure of the product is not allowed in terms of appearance. This requires covering the travel opening directly in front of the travel opening. However, if the operating part of the rigid plate is used to cover the travel opening completely, the area of the operating part should be at least as large as that of the travel opening. In this way, the operating part will protrude beyond the range of the fixed part along with the movement of the movable part, which seems obtrusive. Otherwise, the fixed part has to be extended accordingly to increase the area, and then the bedsheet fixer will become bulky and oversized.

[0022] In addition, air holes for the internal ventilation of the mattress sometimes need to be installed on the vertical curtain of the mattress. If air holes and a bedsheet fixer are installed on the curtain at the same time, it will make the appearance of the mattress complicated and cumbersome, affecting the aesthetics. "A detachable mattress ventilation and fixing device and its detachable mattress CN106880220A" designs the air holes of the mattress to be devices that can be used to fix the fitted sheet or the soft surface layer of the mattress at the same time. However, such a functional integration design is difficult to be truly applied in reality. Generally, the processing of the fitted sheet will be provided with elastic bands at the four corners of the edge of the fitted sheet corresponding to the bottom surface of the mattress to cooperate with the four corners of the mattress to be sleeved from bottom to top, and the processing of the fitted sheet will also ensure that there is enough lower edge part to be used to press under the mattress. This is a common structural style of the fitted sheets sold in the market. Therefore, it is redundant to design the air holes of the mattress to be used to fix the fitted sheet at the same time. Then the possible application is limited to providing the fitted sheet and the mattress to consumers as a whole at one time, but its use effect has no advantage. As for the soft surface layer of the mattress, although it is easy to get dirty and may be damaged, a more appropriate and widely adopted solution is the zippered detachable soft surface layer. When the soft surface layer is dirty, it can be taken off and washed, and when it is damaged, it can be taken off and replaced. Except for the two ends of the zipper, the edge of the soft surface layer can be well joined with the corresponding edge of the mattress through the zipper, which is stable and reliable, and the operation is convenient. This is difficult to achieve by non-zipper methods. In contrast, when the air holes of the mattress are designed to be used to fix the soft surface layer at the same time, the fixing effect becomes worse. Such an integration of functional structures is meaningless. Moreover, the structure designed to fix the fitted sheet or the soft surface layer of the mattress is cumbersome, including components that can be detached from the mattress, and the components that can be detached from the mattress need to be correspondingly configured to the fitted sheet or the soft surface layer of the mattress. In this way, both the processing of the product and the use of the final product are too cumbersome and lack practical value. Summary of the Invention

[0023] In view of the above related technical problems, the present invention provides a mattress with a flexible connection in a sheet fixing structure to solve them.

[0024] A mattress with a flexible connection in a sheet fixing structure, a sheet fixer is installed on the vertical surface of the mattress. The sheet fixer includes a fixing part and an operating part. The sheet fixer is installed on the vertical surface of the mattress through the fixing part. There is a detachable connection structure between the operating part and the fixing part for connecting the sheet, and the operating part is movably connected to the fixing part through a flat belt made of flexible material.

[0025] In a possible implementation, the fixing part is provided with a first elongated hole corresponding to the flat belt, and / or, the operating part is provided with a second elongated hole corresponding to the flat belt.

[0026] In a possible implementation, the fixing part includes a top plate, the top plate is provided with the first elongated hole, one end of the flat belt is connected to the top plate through the first elongated hole, and the other end of the flat belt is connected to the back of the operating part before.

[0027] In a possible implementation, the operating part is provided with a push head, the push head has a hook part, and the inside of the hook of the hook part is used as a clamping position. The fixing part is provided with a pushing hole corresponding to the push head and a plugging hole corresponding to the clamping position. The pushing hole and the plugging hole are an integral large and small opening. The pushing hole is larger than the plugging hole and is below the plugging hole. The stretchable length of the flat belt satisfies that while the operating part remains connected to the fixing part, the push head can pass through the pushing hole against the part of the sheet and the clamping position can move upward into the plugging hole;

[0028] In a possible implementation, a movable part that can move up and down is installed on the fixing part. An elastic part is provided between the movable part and the fixing part. The elastic part elastically restricts the movement of the movable part. The stretchable length of the flat belt satisfies that while the operating part remains connected to the fixing part, the operating part can cooperate with the movable part to connect the sheet and move with the connected part of the sheet and the movement of the movable part.

[0029] In a possible implementation, the fixing part includes a main fixing plate, the main fixing plate is provided with a travel opening for the movable part to move. The width of the flat belt is greater than or equal to the width of the travel opening. The flat belt and the operating part can cooperate to cover the travel opening directly in front of the travel opening.

[0030] In a possible implementation, the elastic part is a spring, and there are two springs which are respectively connected to the left and right of the back of the movable part.

[0031] In a possible implementation, the fixing part includes a back plate which is located behind the moving part. Mounting holes are provided at the four corners of the back side of the fixing part, and notches for yielding are provided at the four corners of the back plate corresponding to the four mounting holes and their hole walls respectively.

[0032] In a possible implementation, the flat belt is elastic.

[0033] In a possible implementation, the sheet fastener includes air holes for the interior of the mattress to breathe.

[0034] In summary, the beneficial effects of the present invention can be known as follows:

[0035] First, the sheet fastener mounted on the vertical surface of the mattress, in which each component is connected as a whole, has no hidden danger of component loss. Moreover, the operating part of the fixing part is connected by a flat belt made of a flexible material, which has higher flexibility and usability compared with directly connecting the fixing part. Also, due to the shape and length of the flat belt being only a short section, the movement degree of the operating part in the left-right direction is reasonably restricted, that is, the flipping of the operating part in the left-right direction will not cause the wrong inversion of its front and back sides.

[0036] Second, while the two ends of the flat belt made of a flexible material are respectively connected to the fixing part and the operating part, the flat belt can adapt to the up-and-down movement of the operating part relative to the fixing part.

[0037] Third, when the fixing part is provided with a moving part, the flat belt and the operating part cooperate to cover the structure directly in front of the moving limit structure, making the sheet fastener more integral visually, and thus can be properly integrated with the mattress in appearance, which is beneficial to the beauty of the mattress.

[0038] Fourth, for the elastic flat belt, after the corresponding size is set as required, its elasticity can avoid the phenomenon of the flat belt being bent and bulged, and can make the appearance of the sheet fastener and even the mattress simpler.

[0039] Fifth, it serves multiple purposes. Since the flexible flat belt is used for transitional connection between the operating part and the fixing part, the sheet fastener obtains a synergistic optimization effect in terms of simple structure, flexible operation, and integration with the mattress in appearance.

[0040] Sixth, the sheet fastener integrates air holes for the interior of the mattress to breathe, serving two purposes with one device, simplifying the devices for realizing the functions of the mattress. And since fixing the sheet is a basic requirement for using the mattress, such functional integration has more universal practical value. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Embodiment 1, as Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 shown in

[0054] The sheet fixing structure includes a mattress (35) with a flexible connection. As Figure 7 shown, a sheet fixer (1) is installed on the vertical surface (36) of the mattress. The sheet fixer (1) includes a fixing part (4) and an operating part (27). The sheet fixer (1) is mounted on the vertical surface (36) of the mattress through the fixing part (4). A detachable connection structure (33) is provided between the operating part (27) and the fixing part (4) for connecting the sheet, and the operating part (27) is movably connected to the fixing part (4) through a flat belt (2) made of flexible material and thus remains connected to the fixing part (4).

[0055] The flexible material can be bent and stretched, that is, the flat belt (2) can be bent and can be re-straightened and stretched after bending. On the premise of meeting the requirements of being bendable and stretchable, the material of the flat belt (2) includes but is not limited to one or more of fabric, plastic, leather, rubber, and metal.

[0056] As Figure 2 shown, the operating part (27) is provided with a push head (29). The push head (29) has a hook part (31), and the inside of the hook of the hook part (31) is used as a clamping position (32). The fixing part (4) is provided with a pushing hole (11) corresponding to the push head (29) and a plugging port (12) corresponding to the clamping position (32). The pushing hole (11) and the plugging port (12) are an integral large opening (13). As Figure 7As shown, the pushing hole (11) is larger than the clamping port (12) and is located below the clamping port. The stretchable length of the flat belt (2) is such that while the operating part (27) remains connected to the fixing part (4), the pushing head (29) can pass through the pushing hole (11) at the position against the bedsheet and the clamping position (32) can move upward into the clamping port (12).

[0057] The stretchable length refers to both the inelastic flat belt (2) and the elastic flat belt (2). When the flat belt (2) is inelastic, the stretchable length refers to the length when the flat belt (2) is stretched into a straight state; when the flat belt (2) is elastic, the stretchable length refers to the length when the flat belt (2) is stretched with force.

[0058] The fixing part (4) includes a main fixing plate (5) and a top plate (6), a bottom plate (7), a left side plate (8), and a right side plate (9). The top plate (6), the bottom plate (7), the left side plate (8), and the right side plate (9) are all fixedly connected to the edge of the main fixing plate (5). The back of the top plate (6), the back of the bottom plate (7), the back of the left side plate (8), and the back of the right side plate (9) respectively form internal corners with the back of the main fixing plate (5). The large opening (13) is located on the main fixing plate (5), and expansion joints (14) are provided on both sides of the main fixing plate (5) at the transition between the pushing hole (11) and the clamping port (12).

[0059] The operating part (27) includes a surface plate (28). The pushing head (29) is located on the back of the surface plate (28). The pushing head (29) is fixedly connected to the back of the surface plate (28) through a connecting column (30). The part of the pushing head (29) that laterally extends beyond the connection point with the connecting column (30) and is beside the connecting column (30) is the hook part (31). The distance between the hook part (31) and the back of the surface plate (28) is the hook interior, and the hook interior is used as the clamping position (32) to move into the clamping port (12) to accommodate the outer edge of the clamping port (12). The outer edge of the clamping port (12) is clamped in the clamping position (32), so that the pushing head (29) is detachably connected to the main fixing plate (5) to form the detachable connection structure (33).

[0060] As Figure 3 、 Figure 1As shown, a first elongated hole (10) is provided in the top plate (6) corresponding to the flat belt (2), and a second elongated hole (34) is provided in the top of the front plate (28) corresponding to the flat belt (2). One end of the flat belt (2) is connected to the top plate (6) through the first elongated hole (10), and the other end of the flat belt (2) is connected to the top of the front plate (28) through the second elongated hole (34) and is located in front of the back surface of the operation part (27).

[0061] In this embodiment, the flat belt (2) is elastic, so that the length of the flat belt (2) in the stationary state can be shortened, thereby reducing the degree of zigzag protrusion of the flat belt (2), and even avoiding the phenomenon of zigzag protrusion of the flat belt (2).

[0062] As Figure 3 shown, four mounting holes (26) are distributed on the back surface of the fixing part (4), and the sheet fastener (1) is mounted on the vertical surface (36) of the mattress through the four mounting holes (26), as Figure 8 shown, a plurality of the sheet fasteners (1) are distributed and mounted on the vertical surface (36) of the mattress (35) around the mattress.

[0063] Embodiment 2. This embodiment is a combined implementation of Embodiment 1 and the following description:

[0064] The sheet fastener (1) includes air holes (3) for the mattress (35) to breathe internally, and a ventilation opening is provided in the surrounding cloth of the vertical surface (36) of the mattress corresponding to the air holes (3). The fixing part (4) includes a back plate (21), the back plate (21) is located behind the main fixing plate (5), and the back plate (21) is fixedly connected to the main fixing plate (5) through the top plate (6), the bottom plate (7), the left side plate (8), and the right side plate (9). A cavity is formed between the back plate (21) and the main fixing plate (5); the air holes (3) include a back plate air hole (211), a left side air hole (81), and a right side air hole (91). The back plate (21) is provided with the back plate air hole (211), the left side plate (8) is provided with the left side air hole (81), and the right side plate (9) is provided with the right side air hole (91).

[0065] Embodiment 3, as Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 shown:

[0066] The sheet fixing structure includes a flexible-connected mattress (35), as Figure 8 shown, the vertical surface (36) of the mattress is equipped with a sheet fastener (1), as Figure 5As shown, the sheet fastener (1) includes a fixing part (4) and an operating part (27). The sheet fastener (1) is attached to the vertical surface (36) of the mattress through the fixing part (4). There is a detachable connection structure (33) between the operating part (27) and the fixing part (4) for connecting the sheet, and the operating part (27) is movably connected to the fixing part (4) by a flat belt (2) made of a flexible material and thus remains connected to the fixing part (4).

In this embodiment, there are five elastic hooks (16), and the five elastic hooks (16) can form an encircling and hooking effect on the push head (29).

[0074] As Figure 6 、 Figure 4 shown, the top plate (6) is provided with a first strip hole (10) corresponding to the flat belt (2), the top of the front panel (28) is provided with a second strip hole (34) corresponding to the flat belt (2), one end of the flat belt (2) is connected to the top plate (6) through the first strip hole (10), and the other end of the flat belt (2) is connected to the top of the front panel (28) through the second strip hole (34) and is in front of the back of the operating part (27).

[0075] In this embodiment, the flat belt (2) is elastic, so that the length of the flat belt (2) in the static state can be shortened, and further the degree of zigzag protrusion of the flat belt (2) can be reduced, and even the phenomenon of zigzag protrusion of the flat belt (2) can be avoided.

[0076] As Figure 4As shown, the flat belt (2) is above the operation part (27). When in a static state, the flat belt (2) cooperates with the operation part (27) to cover the stroke opening (20) directly in front of the stroke opening (20); when the operation part (27) cooperates with the moving part (15) to connect the sheet and move upward together, the lower part of the stroke opening (20) may be exposed, but at this time, it is covered by the sheet.
