Description

Technical Field

[0001] This utility model belongs to the field of mattress technology, specifically relating to a bed core reinforcement spring, a bed core, and a mattress. Background Technology

[0002] To improve the overall structural stability and durability of spring mattresses, prevent the edges from collapsing due to prolonged pressure, and extend their lifespan, existing technologies typically reinforce the sides of the mattress core. For example, this can be achieved by arranging high-stiffness springs around the perimeter of the core, increasing spring density, and using M-type fasteners or Z-type support springs to connect the edge springs to the surrounding steel wires, thereby enhancing the support on the sides of the core.

[0003] However, most current spring mattress core reinforcement measures primarily focus on the straight sides of the core, while the four corners are the weakest points in the mattress structure. Existing side reinforcement methods have limited effectiveness in supporting and strengthening the corners, causing them to easily collapse and deform after long-term use. This not only affects the mattress's aesthetics and comfort but also significantly reduces its overall support performance and lifespan. Furthermore, during mattress production, handling, and installation, the corners are more susceptible to damage from accidental impacts due to the lack of targeted reinforcement. Therefore, a structural design is needed to specifically enhance the support strength and structural stability of the mattress core corners. Utility Model Content

[0004] Based on the aforementioned shortcomings and deficiencies in the existing technology, one of the objectives of this utility model is to at least solve one or more of the aforementioned problems in the existing technology, or to provide a bed core reinforcement support spring, bed core, and mattress that meets one or more of the aforementioned needs.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution: This utility model provides a bed core reinforcement support spring, comprising a metal wire integrally bent into shape: The elastic metal wire includes a first support rod, a second support rod, a first elastic support part, and a second elastic support part; The first elastic support part is integrally connected to one end of the first support rod and one end of the second support rod; The second elastic support is integrally connected to the other end of the first support rod and the other end of the second support rod; Both the first elastic support and the second elastic support can provide elastic support forces that move away from each other along the first direction to the first support rod and the second support rod. The first and second support rods are bent at a preset angle to fit the corners of the mattress and receive elastic support force, thereby providing support to the mattress in a first direction. In a preferred embodiment, both the first elastic support and the second elastic support include an elastic loop and a first connecting arm and a second connecting arm extending from the elastic loop. The first connecting arm is connected to the first support rod, and the second connecting arm is connected to the second support rod.

[0006] As a further preferred embodiment, the radius of the elastic loop is 10-30 mm.

[0007] As a further preferred embodiment, the connection between the first connecting arm and the first support rod, and the connection between the second connecting arm and the second support rod, adopts a rounded transition with a radius of 10-50mm.

[0008] In a preferred embodiment, the lengths of the first support rod and the second support rod are 100-400mm.

[0009] In a preferred embodiment, the diameter of the metal wire is 2-3.5 mm.

[0010] In one preferred embodiment, the height of the bed core reinforcement spring along the first direction is 60-300mm.

[0011] On the other hand, the present invention also provides a bed core, including a perimeter steel, and the bed core further includes a bed core reinforcing support spring as described in any one of the above-mentioned methods; The bed core reinforcement spring is located at the corner of the bed core, and the first support rod and the second support rod are fixedly connected to the surrounding steel.

[0012] On the other hand, the present invention also provides a mattress, including a mattress core, the mattress core including a edging steel, and the mattress core including a mattress core reinforcing support spring as described in any one of the above. The bed core reinforcement spring is located at the corner of the bed core, and the first support rod and the second support rod are fixedly connected to the surrounding steel.

[0013] In a preferred embodiment, the first support rod, the second support rod, and the edging steel are fixedly connected using nail guns.

[0014] Compared with the prior art, the advantages of this utility model are: When the bed core reinforcement support spring of this utility model is installed at the corner of the bed core, its first and second support rods, which are bent at a preset angle, can be tightly fitted and fixed to the edge steel of the corner of the mattress. Through the elastic support of the first and second elastic support parts in its structure, a continuous elastic support force is applied to the first and second support rods, moving away from each other along the first direction.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0018] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The following description with reference to the accompanying drawings is provided to aid in understanding exemplary embodiments of the present invention as defined by the claims and their equivalents. It includes various specific details to aid understanding, but these are to be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. Furthermore, to make the specification clearer and more concise, detailed descriptions of functions and structures well known in the art will be omitted.

[0019] Example 1: This embodiment provides a bed core reinforcement support spring. Its structural schematic diagram is shown below. Figures 1 to 3 It includes a bent metal wire.

[0020] The metal wire is wound to form a closed shape with a specific three-dimensional structure, and connection points are provided to connect the two ends into one piece. The metal wire is segmented and integrally bent to form a first support rod 1, a first elastic support part 3, a second support rod 2, and a second elastic support part 4. The wire diameter is preferably 2-3.5 mm to ensure sufficient strength.

[0021] Reference Figure 4 In this embodiment, the connection point where the ends of the metal wires are connected is set on the first support rod 1, where the two ends are welded together, or a constraint ring is used to constrain the two ends. In other embodiments, the connection point can also be set on other parts of the bed core reinforcement support spring.

[0022] The first support rod 1 is a rod-shaped structure located on the upper part of the bed core's reinforcing support spring. The first support rod 1 is bent at its midpoint along its length, with a rounded corner forming a 90-degree angle on the inside. This bend is designed to correspond to and fit the apex of the bed core's corner, while the rod sections on both sides of the bend are used to fit and fix to the edge steel of the bed core.

[0023] The structure of the second support rod 2 is similar to that of the first support rod 1, also being a rod-shaped structure with a bend in the middle, and its bending angle and rounded corner shape correspond to those of the first support rod 1. The difference is that, in the installed state, the first support rod 1 is located above the bed core reinforcing spring, while the second support rod 2 is located below it.

[0024] The first elastic support part 3 and the second elastic support part 4 are both disposed in the middle region of the bed core reinforcing support spring along the vertical direction, located between the first support rod 1 and the second support rod 2, and integrally connected with the first support rod 1 and the second support rod 2 to form a complete elastic structure. Specifically, the first elastic support part 3 is integrally connected to one end of the first support rod 1 and the corresponding end of the second support rod 2, and the second elastic support part 4 is integrally connected to the other end of the first support rod 1 and the corresponding other end of the second support rod 2.

[0025] In a preferred design, the total length of the first support rod 1 and the second support rod 2 can be 100-400mm, the bend is located at the center of its length, and the length of the rod portion on both sides of the bend can be 50-200mm respectively.

[0026] Reference Figure 1 and Figure 2 The core structure of the first elastic support part 3 is its elastic loop 301 located in the middle. A first connecting arm and a second connecting arm extend integrally from both ends of the elastic loop 301. The first connecting arm is smoothly connected to one end of the first support rod 1 at a certain angle, and the connection point preferably forms a rounded corner transition to ensure connection strength and smooth elastic transmission. Similarly, the second connecting arm is also smoothly connected to the corresponding end of the second support rod 2 at a certain angle, and the connection point is also preferably formed with a rounded corner transition.

[0027] The structure of the second elastic support part 4 is basically the same as or symmetrical to that of the first elastic support part 3. It also includes a central elastic loop and first connecting arms and second connecting arms extending from both ends of the loop and respectively connecting to the other ends of the first support rod 1 and the second support rod 2. Specifically, the radius of the elastic loop is preferably 10-30 mm to provide suitable elastic deformation space and support force. The radius R of the fillet at the transition between the first connecting arm, the second connecting arm and the first support rod 1, and the second support rod 2 is preferably 10-50 mm.

[0028] The total height of the bed core reinforcement spring along the vertical direction in the above structure is preferably 60-300mm to accommodate bed core designs of different thicknesses.

[0029] When the bed core reinforcement spring of this embodiment is installed at the corner of the bed core, the upper first support rod 1 is tightly attached to the upper edge of the corner of the bed core, the bend of the first support rod 1 is aligned with and attached to the vertex of the corner of the bed core, and the rod body parts on both sides of the bend are fixedly connected to the upper edge steel of the bed core by means of, for example, nails. Similarly, the lower second support rod 2 is tightly attached to the lower edge of the corner of the bed core, the bend of the second support rod 2 is also aligned with and attached to the vertex of the corner of the bed core, and the rod body parts on both sides of the bend are fixedly connected to the lower edge steel of the bed core. During operation, the elastic loops of the first elastic support part 3 and the second elastic support part 4 can transmit the rebound force to the first support rod 1 and the second support rod 2 along the connecting arm. Specifically, when the first support rod 1 and the second support rod 2 are subjected to an external force and tend to move closer to each other in the first direction, the elastic loops in the first elastic support part 3 and the second elastic support part 4 can undergo elastic deformation, thereby generating a rebound force. The rebound force is transmitted to the first support rod 1 and the second support rod 2 through their respective first and second connecting arms, generating a supporting force that keeps the first support rod 1 and the second support rod 2 away from each other along a first direction, thereby maintaining the distance between the first support rod 1 and the second support rod 2 along the first direction. Specifically, the bed core reinforcement support spring of this embodiment is installed at the corner of the bed core, with the first direction set vertically. When the corner of the bed core is subjected to vertical pressure, attempting to bring the first support rod 1 and the second support rod 2 closer together, the elastic support part generates an elastic supporting force that keeps the first support rod 1 and the second support rod 2 away from each other along the vertical direction. This force causes the first support rod 1 to provide upward support to the upper part of the mattress corner, while the second support rod 2 provides downward support to the lower part of the mattress corner. This continuous elastic support works together at the corners of the mattress, effectively providing stable support in the vertical direction. It can resist vertical pressure from the outside and maintain the original spacing between the top and bottom of the mattress corners, thereby significantly enhancing the support strength and structural stability of the mattress core corners and effectively preventing the corners from collapsing or deforming due to uneven force or long-term pressure.

[0030] Example 2: The difference between the bed core reinforcement spring in this embodiment and that in Embodiment 1 is that, please refer to [link / reference needed]. Figure 5 and Figure 6 The first elastic support 3 and the second elastic support 4 are still bent in the horizontal direction. From the top view, the first elastic support 3 and the second elastic support 4 are bent 90 degrees toward the bed core.

[0031] In Example 1, when the number of springs at the corner of the bed core that are in contact with the bed core reinforcing spring is small, such as 2*2 springs or a single spring, the first and second elastic support parts may interfere with each other due to their close proximity, affecting the bed core's support strength. In this embodiment, the bed core reinforcing spring bends the elastic support part by 90 degrees, avoiding the problem of the first and second elastic support parts being too close. Simultaneously, the elastic support part bends towards the bed core, allowing it to extend into the bed core and engage with the spring located at the edge of the bed core, making the bed core reinforcing spring more securely installed.

[0032] Other structures can be found in Example 1.

[0033] Example 3: This utility model also provides a bed core. (See reference...) Figure 8 The bed core includes a bed core body and bed core reinforcing support springs located at the four corners of the bed core body.

[0034] The mattress core is the main component that forms the mattress's support structure. It can employ various common structures, such as a core composed of multiple individual pocket springs. The top and bottom edges of the mattress core typically have edge steel, which serves to constrain the overall shape of the core and provide connection and support for the edge springs.

[0035] The bed core reinforcement spring adopts the structure of the bed core reinforcement spring as in Example 1. In the reinforced bed core of this embodiment, four bed core reinforcement springs are respectively installed at the four corner positions of the bed core body.

[0036] Figure 9 yes Figure 8 The enlarged view shows that during installation, the bent portion of the first support rod of the bed core reinforcing spring rests against the upper edge of the bed core corner. The two sides of the bent portion of the first support rod are respectively attached to and fixedly connected to the two parts of the upper edging steel of the bed core that form an arc angle at the corner. Similarly, the bent portion of the second support rod of the bed core reinforcing spring rests against the lower edge of the bed core corner. The two sides of the bent portion of the second support rod are respectively attached to and fixedly connected to the two parts of the lower edging steel of the bed core that form an arc angle at the corner.

[0037] By incorporating reinforcing springs at each corner of the mattress core where reinforcement is needed, and reliably securing them to the edge steel, the mattress core of this embodiment significantly improves corner support and anti-collapse capabilities, thereby enhancing the overall durability and lifespan of the mattress. When the corners are under pressure, the reinforcing springs provide vertical elastic support, maintaining the shape and height of the corners and improving the overall comfort and stability of the mattress.

[0038] Example 4: This utility model also provides a reinforced mattress. (See reference...) Figure 7 The reinforced mattress includes a core and a sponge edge protector and a edging fabric surrounding the core, a bottom layer at the bottom of the core and a support layer and a top layer at the top of the core, wherein the four corners of the core are fitted with core reinforcement springs as in Example 1.

[0039] The mattress core provides support within the mattress, and its structure is as follows: Figure 8 As shown, various common core structures can be used, such as cores composed of multiple individual pocket springs. The core is typically surrounded by a rim steel frame, which serves to constrain the overall shape of the core and provide connection and support for the edge springs.

[0040] The bed core reinforcement spring adopts the structure of the bed core reinforcement spring as in Example 1. In the reinforced bed core of this embodiment, four bed core reinforcement springs are respectively installed at the four corner positions of the bed core.

[0041] Figure 9 yes Figure 8 The enlarged view shows that during installation, the bent portion of the first support rod of the bed core reinforcing spring rests against the upper edge of the bed core corner. The two sides of the bent portion of the first support rod are respectively attached to and fixedly connected to the two parts of the upper edging steel of the bed core that form an arc angle at the corner. Similarly, the bent portion of the second support rod of the bed core reinforcing spring rests against the lower edge of the bed core corner. The two sides of the bent portion of the second support rod are respectively attached to and fixedly connected to the two parts of the lower edging steel of the bed core that form an arc angle at the corner.

[0042] By incorporating reinforcing springs at each corner of the mattress core that requires reinforcement, and reliably securing them to the edge steel, the mattress core used in this embodiment significantly enhances corner support and anti-collapse capabilities, thereby improving the overall durability and lifespan of the mattress. When the corners are under pressure, the reinforcing springs provide vertical elastic support, maintaining the shape and height of the corners and improving the overall comfort and stability of the mattress.
