Description

Technical Field

[0001] This utility model relates to the field of mattresses, and in particular to a mattress with added counterweights. Background Technology

[0002] Existing cabinet mattresses are mostly used in small apartments, multi-functional rooms, or temporary guest bedrooms. Common types include side-flip and upright-flip mattresses. The mattress body 1 can be flipped upright and stored in the cabinet 5 via a connecting damper. The damper is located at the connection between the cabinet 5 and the bed frame 6. The upright-flip type, for example... Figure 1 and Figure 2 As shown, the flipping axis of the mattress body is parallel to its short side, creating a flipping effect around the headboard. The mattress body 1 and the cabinet 5 that houses it are relatively tall; the side-flipping type is as follows: Figure 3 and Figure 4 As shown, the flipping axis of the mattress body is parallel to its long side, creating an effect of flipping around the side of the bed. The mattress body 1 and the cabinet 5 that stores it are relatively low. Both mattresses use dampers to cushion and quiet the process of flipping and storing, and to prevent direct impact on the cabinet. In practical use, the above design often leads to inconvenience due to improper mattress weight matching. For example, if the overall weight of the mattress is light (less than 15 kg), when the body leaves the mattress, the rebound force of the damper itself will be greater than the downward pressure of the mattress. Under the action of the damper, the mattress will not be able to maintain a horizontal unfolded state, and the mattress will automatically flip up and slowly retract into the cabinet along the traction force of the damper, resulting in inconvenience. Inconvenience caused by inconvenience will cause trouble and many inconveniences for users. For example, when getting up to retrieve an item, the mattress may suddenly flip up and need to be manually flattened again before it can be used again. When returning after getting up at night, the mattress may have automatically retracted and needs to be flattened again, which seriously affects the efficiency of sleep and rest. For the elderly, children, or disabled people with limited mobility, the extra flattening operation will greatly increase the difficulty of using the mattress and cause inconvenience. Utility Model Content

[0003] To address the technical problem of lightweight cabinet mattresses automatically flipping up after a person leaves the mattress, causing inconvenience and confusion for users, this invention provides a mattress with added counterweights. Without altering the existing structure or spring material, the mattress can be increased by adding counterweights internally. The torque generated by the counterweights and the mattress's original weight counteracts the flipping torque of the damper, preventing the mattress from automatically flipping up after a person leaves and causing inconvenience. Furthermore, the counterweights are strategically placed inside the mattress, preventing it from tilting to one side and not affecting the connection between the bed frame and the damper, thus having no impact on the mattress's lifespan.

[0004] The technical solution adopted by this utility model to solve the technical problem is: a mattress with added counterweights, including a mattress body connected with a damper, wherein the mattress body can be flipped and stored through the damper, characterized in that the counterweights are set inside the mattress body, the counterweights are located in the middle area of ​​the mattress body, or are symmetrically distributed on the left and right sides of the mattress body on one side of the damper. This invention incorporates a counterweight within the mattress body to increase the overall weight of the mattress. The torque generated by the combined weight of the counterweight and the mattress body counteracts the resistance torque of the damper, which causes the mattress to flip and fold up. This prevents the mattress from accidentally folding up after the user leaves. The counterweight can be located in the middle of the mattress body or symmetrically distributed on one side of the mattress body near the damper, preventing the mattress from tilting to one side due to improper placement of the counterweight. The counterweight's placement on the damper side of the mattress body not only avoids affecting the connection area between the damper and the mattress body but also helps increase the "static pressure" at the damper's connection point. This allows the internal friction structures of the damper, such as hydraulic rods or springs, to maintain a stable locked state, requiring a greater pushing force to overcome this locked state of damping resistance.

[0005] As a further improvement and supplement to the above technical solution, this utility model adopts the following technical measures: the counterweight is centrally located in the middle of the mattress body, or arranged in a U-shape around the three sides of the mattress body, or concentrated at the end of the mattress body away from the damper. These three layouts of the counterweight can increase the overall weight of the mattress and keep the center of gravity of the mattress in the middle area, thereby maintaining the mattress's balance and preventing the mattress from tilting to one side even though it will not automatically flip up. The centrally located counterweight is situated in the middle area of ​​the mattress body, while the surrounding and concentrated counterweights are symmetrically distributed on one side of the damper.

[0006] The centrally located counterweight is positioned in the middle area of ​​the mattress body and extends along the direction perpendicular to the mattress body's rotation axis. The surrounding counterweight is positioned as a U-shaped extension around the three sides of the mattress body on the damper side, with the opening of the U-shape facing the damper and the center line of the U-shape perpendicular to the mattress body's rotation axis. The concentrated counterweight is positioned at the end of the mattress body away from the damper, with the extension direction of the counterweight parallel to the mattress body's rotation axis. The centrally located counterweight extends in the middle area of ​​the mattress body along the direction perpendicular to the rotation axis. The surrounding counterweight extends around the mattress body around the damper (i.e., the side where the rotation axis is located), forming a U-shaped surround with the opening facing the damper, and the center line of the U-shape perpendicular to the mattress body's rotation axis. The concentrated counterweight extends at the end away from the damper, in a direction parallel to the rotation axis.

[0007] The distance between the end of the centrally located counterweight and the edge of the mattress body on the same side as the damper is 5-10 cm, and the weight of the counterweight is 4-6 kg. By limiting the weight of the counterweight and the distance between the far end of the counterweight relative to the damper and the edge of the mattress body on the same side as the damper, the counterweight achieves the best effect in preventing the mattress body from rolling over.

[0008] When the flipping axis of the mattress body is parallel to the short side of the mattress body, the length of the counterweight is 170-185cm; when the flipping axis of the mattress body is parallel to the long side of the mattress body, the length of the counterweight is 120-140cm. When the flipping axis of the mattress body is parallel to the short side, i.e., the mattress is a vertical flipping type, the counterweight can be a whole steel bar or segmented steel blocks with a length of 170-185cm, and the extension direction of the counterweight is parallel to the long side of the mattress; when the flipping axis of the mattress body is parallel to the short side, i.e., the mattress is a side-flipping type, the counterweight can be a whole steel bar or segmented steel blocks with a length of 120-140cm, and the extension direction of the counterweight is parallel to the short side of the mattress.

[0009] When the flipping axis of the mattress body is parallel to the short side of the mattress body, the U-shaped extension of the counterweight consists of two long side segments and one short side segment. The two long side segments are located on the two long side sides of the mattress body and extend along the long side direction, respectively. The two long side segments are symmetrical. The short side segment extends along the short side direction on the short side of the mattress body away from the damper. The extension lines at both ends of the short side segment intersect the ends of the two long side segments. When the flipping axis of the mattress body is parallel to the short side of the mattress body, i.e., the mattress is a vertical flipping type, the U-shaped extended counterweight consists of two long and one short segment. The two long side segments correspond to the two long side sides of the mattress body, respectively, and the short side segment corresponds to the short side of the mattress body away from the damper, i.e., the foot of the bed. At the same time, the extension lines at both ends of the short side segment intersect the ends of the two long side segments to form a U-shaped wraparound arrangement.

[0010] When the flipping axis of the mattress body is parallel to the long side of the mattress body, the U-shaped extension of the counterweight consists of two short side segments and one long side segment. The two short side segments are located on the two short sides of the mattress body and extend along the short side direction, respectively. The two short side segments are symmetrical from left to right. The long side segment extends along the long side of the mattress body away from the damper, and the extension lines at both ends of the long side segment intersect the ends of the two short side segments. When the flipping axis of the mattress body is parallel to the long side of the mattress body, i.e., the mattress is side-flipped, the U-shaped extended counterweight consists of two short and one long side segments. The two short side segments correspond to the two short sides of the headboard and footboard of the mattress body, respectively, and the long side segment corresponds to the long side of the mattress body away from the damper. At the same time, the extension lines at both ends of the long side segment intersect the ends of the two short side segments to form a U-shaped wraparound arrangement.

[0011] The centrally located counterweight extends along the direction parallel to the mattress body's rotation axis on the side of the mattress body away from the damper. The distances from both ends of the counterweight to the corresponding edges of the mattress body are equal. The mattress includes at least one centrally located counterweight, and when there are multiple centrally located counterweights, they are arranged side-by-side along a direction perpendicular to the mattress body's rotation axis. The total weight of all counterweights is between 4 and 6 kilograms. The centrally located counterweights all extend along the mattress body side-by-side on the side away from the damper, along a direction parallel to the mattress body's rotation axis, with both ends extending to the corresponding edges of the mattress body at equal distances, ensuring left-right symmetry in the length direction of the counterweights. There can be one or more counterweights; in the case of multiple counterweights, they are arranged side-by-side along a direction perpendicular to the rotation axis.

[0012] The counterweight is either a steel bar inserted through the mattress body or a steel block embedded in the bottom of the mattress body. The counterweight can be either an inserted steel bar or an embedded steel block. Insertion allows full utilization of the gaps in the spring core, while embedding can be done by slotting the steel block into the bottommost padding layer of the mattress body. Both steel bars and blocks are readily available, low in cost, and effective. The counterweight can be a single, straight steel bar or segmented steel blocks arranged in a straight line.

[0013] The mattress body includes a spring core, and the steel strips are inserted inside the spring core. The steel strips are either fixedly connected to the springs inside the spring core or detachably connected. The mattress body contains a spring core, and the steel strips are inserted into the gaps within the spring core. The steel strips and springs can be securely connected by welding or detachable connections such as cable ties to prevent displacement of the steel strips.

[0014] The beneficial technical effects of this utility model are as follows: By setting a counterweight inside the mattress body, the overall weight of the mattress is increased. The counterweight and the mattress body work together to generate a torque to counteract the resistance torque of the damper, which causes the mattress to flip and fold up, preventing the mattress from being accidentally folded up after the person leaves. The counterweight can be set in the middle area of ​​the mattress body to form a central setting, or it can be symmetrically distributed on the left and right sides of the mattress body on one side of the damper to form a surrounding setting or a concentrated setting. The counterweight will not cause the mattress body to tilt to one side, nor will it affect the connection area between the damper and the mattress body. Furthermore, after setting the counterweight on the mattress body, it can also increase the "static pressure" at the connection of the damper, making the inside of the damper tend to be a stable locked state. Only when a greater pushing force is applied can the locked state be broken and the mattress flipped up. This utility model is applicable to common upright or side-flipping mattresses.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] like Figure 5 As shown, Embodiment 1 is a mattress with added counterweights. The mattress is a flip-up type and can be flipped and stored or laid flat around the flip axis. The flip axis is the flip axis 3 in the figure. The flip axis 3 is parallel to the short side of the mattress body 1. The mattress includes a mattress body 1 connected with a damper. The mattress body 1 is flipped and stored through the damper. The mattress body 1 is provided with a counterweight 2 inside. The counterweight 2 can be centrally located in the middle area of ​​the mattress body 1. Specifically, the counterweight 2 is in the middle of the mattress body 1 and extends along the direction perpendicular to the flip axis.

[0030] like Figure 8 and Figure 9As shown, the mattress body 1 in this embodiment has a spring core, and the counterweight 2 is a steel bar inserted inside the spring core. The steel bar and the spring 8 inside the spring core are detachably connected and fastened by cable ties 7. Alternatively, the spring can be fixedly connected to the spring by spot welding; the steel bar can also be replaced by several segmented steel blocks and embedded in the bottom of the mattress body 1.

[0031] like Figure 1 As shown, the length of the counterweight 2 is 170-185cm, preferably a single steel bar of 180cm. The distance a from the end of the steel bar away from the damper to the edge of the mattress body 1 on the same side is 5-10cm, and the weight is 4-6kg. In this embodiment, the distance a is preferably 6cm and the weight is 5kg.

[0032] In this embodiment, the steel bar, acting as a counterweight, increases the overall weight of the mattress, generating sufficient downward torque to counteract the upward torque of the damper that causes the mattress to flip and fold, preventing the mattress from automatically flipping and folding after a person leaves the mattress. Simultaneously, the steel bar, centrally located inside the mattress body, distributes its weight evenly along the force line along the mattress's length, preventing the mattress from tilting to one side and ensuring stable and balanced force distribution. The steel bar does not exert any tensile force on the mattress in other directions, nor does it burden the bed frame or damper; it only balances the damping force and does not affect the mattress's lifespan.

[0033] like Figure 6 As shown, Embodiment 2 is also a mattress with added counterweights. Like Embodiment 1, it is also a flip-up type. The flip axis is the flip axis 3 parallel to the short side of the mattress body 1 shown in the figure. The counterweight 2 is also a steel bar inserted inside the spring core. The steel bar and the spring are also tied together with cable ties. The difference from Embodiment 1 is that the counterweight 2 is symmetrically distributed on the mattress body 1 on one side of the damper, and it is arranged in a U-shape around the three sides of the mattress body 1. The arrangement is that the counterweight 2 extends in a U-shape around the three sides of the mattress body 1 on the damper side. The opening of the U-shape faces the damper, and the center line of the U-shape is perpendicular to the flip axis 3.

[0034] As shown in the figure, the U-shaped extension of the counterweight 2 consists of two long side segments and one short side segment. The two long side segments are located on the two long side sides of the mattress body 1 and extend along the long side direction. The two long side segments are symmetrical. The length of a single long side segment is 180cm, and the distance b from one side of the mattress body is 5-10cm, preferably 6cm. The short side segment extends along the short side direction on the short side of the mattress body 1 away from the damper. The extension lines at both ends of the short side segment intersect with the ends of the two long side segments. The length of the short side segment is 130cm, and the distance c from the short side of the mattress body where the foot of the bed is located is also 5-10cm, preferably 5cm. The total weight of the counterweight 2 is 4-6 kg, preferably 5 kg.

[0035] In this embodiment, steel bars are arranged as counterweights around the mattress body, increasing its weight and creating a downward torque to counteract the upward torque of the damper that causes the mattress to flip and fold, preventing the mattress from automatically flipping and folding after the user leaves. Simultaneously, the steel bars encircle three sides of the mattress body and symmetrically distribute the weight, preventing the mattress from tilting to one side. The mattress remains balanced and stable, and since the steel bars on all three sides are on one side of the damper, they do not affect the normal operation of the damper and have no impact on the mattress's lifespan. Alternatively, the steel bars can be replaced with multiple steel blocks embedded within the mattress body.

[0036] like Figure 7 As shown, Example 3 is also a mattress with added counterweights. Like Examples 1 and 2, it is a vertical flip-up type. The flipping axis is the vertical flipping axis 3 parallel to the short side of the mattress body 1, as shown in the figure. The counterweight 2 is also a steel bar inserted into the spring core, and the steel bar and spring are tied together with straps. Similar to Example 2, the counterweight 2 is symmetrically distributed on one side of the mattress body 1 along the damper. The difference is that the counterweight 2 is concentrated at the end of the mattress body 1 furthest from the damper, and the extension direction of the counterweight 2 is parallel to the vertical flipping axis 3. At the same time, both ends of the counterweight 2 extend... The distance between the long sides of the mattress body 1 is equal. There is at least one centrally located counterweight 2 inside the mattress body 1. When there are multiple centrally located counterweights 2, each counterweight 2 is arranged side by side along the direction of the vertical turning axis 3. In this embodiment, there are two counterweights 2, both of which are inserted steel bars. Each steel bar is 140cm long, and the total weight of all the steel bars is 4 to 6 kg, preferably 5 kg. The distance e between the two steel bars is 5 to 10cm, preferably 5cm. The distance d between the short side of the mattress body foot and the adjacent steel bar is 3 to 5cm, preferably 3cm.

[0037] This embodiment also increases the total weight of the mattress by adding counterweights to counteract the torque of the damper. The counterweights are all located on the foot of the mattress, away from the damper, so they have no impact on the lifespan of the damper or the mattress. Furthermore, the counterweights are symmetrically distributed, ensuring balanced force on the mattress and preventing tilting. Because the counterweights are located at the furthest point from the damper, the lever arm and the resulting torque are larger than in Embodiments 1 and 2. This allows for the achievement of the same torque as the aforementioned two embodiments with less counterweight, reducing counterweight costs and the total weight of the mattress. The steel strips in this embodiment can also be replaced with multiple steel blocks embedded in the mattress body.

[0038] like Figure 10As shown, Embodiment 4 is also a mattress with added counterweights, which also includes a mattress body 1 and a counterweight 2 installed therein. The mattress body 1 has a spring core, and the counterweight 2 is also a steel strip that is tied and fixed to the spring with cable ties. Unlike Embodiments 1 to 3, the mattress is a side-flipping type, and the flipping axis is the side-flipping axis 4 parallel to the long side of one side of the mattress body 1 as shown in the figure. As shown in the figure, the counterweight 2 is also centrally located in the middle area of ​​the mattress body 1 and extends along the direction perpendicular to the side-flipping axis 4. The length of the counterweight 2 is 120 to 140 cm, preferably a whole steel strip of 130 cm. The distance f between the end of the steel strip away from the damper and the long side of the mattress body 1 on the same side is 5 to 10 cm, and the weight is 4 to 6 kg. In this embodiment, the preferred distance f is 5 cm and the weight is 5 kg.

[0039] In this embodiment, the steel bar also serves as a counterweight to increase the overall weight of the mattress, generating sufficient torque to counteract the torque of the damper that causes the mattress to flip, preventing the mattress from automatically flipping and collapsing after the person leaves. Furthermore, the steel bar is centrally positioned within the mattress body, distributing the weight evenly so that the mattress does not tilt to one side, ensuring a balanced and stable force distribution. The centrally positioned steel bar does not exert any pulling force on the mattress in other directions, nor does it burden the bed frame or damper; it only balances the damping force and does not affect the mattress's lifespan. Similarly, the steel bar can be replaced with multiple steel blocks embedded in the mattress body.

[0040] like Figure 11 As shown, Embodiment 5 is also a mattress with added counterweights. Like Embodiment 4, it is a side-flipping type. The flipping axis is the side-flipping axis 4 parallel to the long side of the mattress body 1 shown in the figure. The counterweight 2 is a steel bar inserted into the spring core. The steel bar and the spring are also tied together with cable ties. The difference from Embodiment 4 is that the counterweight 2 is symmetrically distributed on the mattress body 1 on one side of the damper and is arranged in a U-shape around the three sides of the mattress body 1. The arrangement is that the counterweight 2 extends in a U-shape around the three sides of the mattress body 1 on the damper side. The opening of the U-shape faces the damper, and the center line of the U-shape is perpendicular to the side-flipping axis 4.

[0041] As shown in the figure, the U-shaped extension of the counterweight 2 consists of two short side segments and one long side segment. The two short side segments are located on the two short side sides of the mattress body 1 and extend along the short side direction. The two short side segments are symmetrical. The short side segments are made of steel bars with a length of 120-140cm, preferably 130cm. The distance g between each short side segment and the short side of one side of the mattress body is 5-10cm, preferably 5cm. The long side segment extends along the long side of the mattress body 1 away from the damper, with a length of 180cm. The distance h between the long side segment and the adjacent long side of the mattress body is 5-10cm, preferably 5cm. The extension lines at both ends of the long side segment intersect with the ends of the two short side segments. The total weight of the counterweight 2 is 4-6 kg, preferably 5 kg.

[0042] In this embodiment, the steel bars also serve as counterweights, encircling the mattress body to increase its weight. This, combined with the mattress body, creates a downward torque to counteract the upward torque of the damper, preventing the mattress from automatically flipping and collapsing after the user leaves. The steel bars encircle three sides of the mattress body, symmetrically distributing the weight, ensuring a balanced and stable mattress that won't tilt to one side. Since the steel bars encircling the mattress are all on one side of the damper, they do not affect the damper's normal operation or the mattress's lifespan. Alternatively, the steel bars can be replaced with multiple steel blocks embedded within the mattress body.

[0043] like Figure 12 As shown, Example 6 is also a mattress with added counterweights. Like Examples 4 and 5, it is a vertical flip-up type. The flipping axis is the side-flipping axis 4, which is parallel to the long side of the mattress body 1 as shown in the figure. The counterweight 2 is also a steel bar inserted into the spring core of the mattress body 1. The steel bar and spring are also tied together with cable ties. Similar to Example 5, the counterweight 2 is symmetrically distributed on one side of the mattress body 1 along the damper. The difference is that the counterweight 2 is concentrated on the long side of the mattress body 1 away from the damper. The extension direction of the counterweight 2 is parallel to the side-flipping axis 4. Simultaneously, the counterweight 2... The two ends of the counterweight 2 extend to the short sides of the corresponding mattress body 1 at equal distances. There is at least one centrally located counterweight 2 inside the mattress body 1. When there are multiple centrally located counterweights 2, each counterweight 2 is arranged side by side along the direction of the vertical side-flipping axis 4. In this embodiment, there are two counterweights 2, both of which are inserted steel bars. Each steel bar is 140cm long, and the total weight of all the steel bars is 4 to 6 kg, preferably 5 kg. The distance m between the two steel bars is 5 to 10cm, preferably 5cm. The distance L between the long side of the mattress body away from the damper and the adjacent steel bar is 3 to 5cm, preferably 5cm.

[0044] This embodiment also increases the total weight of the mattress by adding counterweights to counteract the torque of the damper. The counterweights are all located on the long side away from the damper, so they have no impact on the lifespan of the damper or the mattress. Similarly, the counterweights are symmetrically distributed left and right, ensuring balanced force on the mattress and preventing tilting. Because the counterweights are concentrated on the long side away from the damper, the lever arm and the resulting torque are larger than in embodiments 4 and 5. Only a smaller amount of counterweight is needed to achieve the same torque as the aforementioned two embodiments, reducing counterweight costs and the total weight of the mattress. The steel strips in this embodiment can also be replaced with multiple steel blocks embedded in the mattress body.
