Description

Technical Field

[0001] This utility model relates to the field of bed furniture technology, and in particular to a convenient fitted sheet mattress replacement device based on magnetic fasteners. Background Technology

[0002] A fitted sheet is a type of bedding used to cover a mattress. It usually has elastic around the edges to secure it to the mattress, keeping it flat and preventing it from slipping. Like a "cover," it covers the top and sides of the mattress, effectively preventing dust, sweat, and stains from directly contacting the mattress and extending its lifespan. Compared to traditional flat sheets, fitted sheets are more stable, less prone to wrinkling, and more suitable for people who toss and turn frequently or have high requirements for sleep quality.

[0003] However, traditional fitted sheets with elastic bands on all four sides will age due to repeated stretching and washing after prolonged use, resulting in decreased elasticity, loosening and sagging. This makes the fitted sheet unable to fit snugly against the mattress surface, easily shifting or curling at the edges, affecting the stability and comfort of sleep. As the elastic band ages, it may also break or deform, which not only reduces the lifespan of the fitted sheet but also requires frequent adjustments or even replacements, increasing usage costs and inconvenience. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in existing fitted sheets with elastic bands around the four sides, after prolonged use, the elastic bands age due to repeated stretching and washing, resulting in decreased elasticity, loosening, and sagging. This causes the fitted sheet to fail to fit snugly against the mattress surface, easily shifting or curling, affecting the stability and comfort of sleep. After aging, the elastic bands may also break or the webbing may deform, which not only reduces the lifespan of the fitted sheet but also requires frequent adjustments or even replacements, increasing the cost and inconvenience of use. Therefore, this invention proposes a convenient fitted sheet for mattress replacement based on magnetic fasteners.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A convenient fitted sheet mattress replacement device based on magnetic fasteners includes a mattress body and a vertical guide frame. The vertical guide frame is fixedly connected to the side edge of the mattress body. A plastic block is slidably disposed within the vertical guide frame. A magnetic fastening component is disposed at the other end of the plastic block, which clamps and fixes both ends of the fitted sheet. A counterweight adjustment component is disposed at the bottom of the plastic block. The counterweight adjustment component drives the magnetic fastening component to move vertically along the vertical guide frame, thereby tightening the fitted sheet.

[0006] Optionally, the magnetic fixing component includes an inner cloth strip, an outer cloth strip, and a connecting cloth. The inner cloth strip is fixedly connected to both ends of the inner cloth strip, and the connecting cloth is fixedly connected to the outer cloth strip at the other end. Flat steel sheets are inserted into the inner cavities of both the inner and outer cloth strips.

[0007] Optionally, a first magnet is fixedly connected at equal intervals to the side of the inner fabric strip, and a second magnet is fixedly connected at equal intervals to the side of the outer fabric strip near the first magnet, with the magnetic properties of the opposite faces of the first magnet and the second magnet being opposite.

[0008] Optionally, the counterweight adjustment assembly includes an inner box, a connecting rope, a main counterweight, an auxiliary counterweight, and a fixing screw. The inner box is movably inserted into the bottom of the vertical guide frame, and the fixing screw extends from the outside of the vertical guide frame and is screwed into the inner box.

[0009] Optionally, the inner box is provided with guide grooves at equal intervals along the horizontal direction, and auxiliary counterweights are movably inserted into the guide grooves at equal intervals along the horizontal direction.

[0010] Optionally, both the auxiliary counterweight and the main counterweight have holes on their sides, and the main counterweight is movably inserted into the guide groove located at the edge of the inner box. An adjustment screw is threaded into the side of the main counterweight, and one end of the adjustment screw extends into the hole on the side of the auxiliary counterweight.

[0011] Optionally, the top of the main counterweight is fixedly connected to one end of the connecting rope, and the other end of the connecting rope is fixedly connected to the plastic block.

[0012] Compared with the prior art, the present invention has the following advantages: 1. This device achieves automatic guidance and precise positioning of the fitted sheet edge by setting a vertical guide frame and a sliding plastic block inside the side of the mattress. The magnetic fixing component at the end of the plastic block consists of an inner cloth tape, an outer cloth tape, and an inserted flat steel plate, which are firmly attracted by magnets of opposite polarity. This allows the fitted sheet to be clamped into place quickly, without being affected by the aging of the elastic band, ensuring clamping strength and maintaining a stable fit. It effectively avoids the defects of traditional fitted sheets, such as easy displacement, easy curling, and difficulty in alignment, thus improving installation efficiency and fit quality.

[0013] 2. This device provides continuous and adjustable downward tension to the magnetic fixing part through a counterweight adjustment component. The internal box contains a main counterweight and an optional auxiliary counterweight. Users can adjust the counterweight combination through the guide groove and adjustment screw to achieve the best tension effect for different mattress thicknesses and materials. The counterweight is guided by the vertical guide frame, so it will not swing or fall off, and can keep the fitted sheet flat and wrinkle-free for a long time. At the same time, the counterweight is enclosed in the internal box to avoid the safety hazard caused by the exposed counterweight slipping off. It is especially suitable for families with children, significantly improving the overall safety and reliability of use. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-4 A convenient mattress cover replacement device based on magnetic fasteners includes a mattress body 1 and a vertical guide frame 2. The vertical guide frame 2 is fixed to the side edge of the mattress body 1 by screws. A sliding cavity is opened on the side of the vertical guide frame 2. A plastic block 6 is slidably disposed in the vertical guide frame 2 and extends into the sliding cavity. A magnetic fixing component is provided at the other end of the plastic block 6, and the magnetic fixing component clamps and fixes the two ends of the mattress cover.

[0021] The magnetic fixing assembly includes an inner fabric strip 4, an outer fabric strip 7, and a connecting fabric 5. The inner fabric strip 4 is fixedly connected to both ends of the connecting fabric strip 5, and the outer fabric strip 7 is fixedly connected to the other end of the connecting fabric strip 5. The inner fabric strip 4 and the outer fabric strip 7 form a clamping cavity that can hold the edge of the fitted sheet. To improve the overall stiffness and clamping stability of the fabric strips, flat steel plates 3 are inserted into the inner cavities of both the inner fabric strip 4 and the outer fabric strip 7, so that the fabric strips do not fold or deform when subjected to magnetic attraction, ensuring that the edge of the fitted sheet remains flat. The inner fabric strip 4 is fixedly connected to the side at equal intervals with a first magnet 41, and the outer fabric strip 7 is fixedly connected to the side at equal intervals with a second magnet 71 near the first magnet 41. The magnetic properties of the opposite surfaces of the first magnet 41 and the second magnet 71 are opposite, so that the inner fabric strip 4 and the outer fabric strip 7 can automatically attract and clamp the fitted sheet fabric when they are close to each other.

[0022] The bottom of the plastic block 6 is equipped with a counterweight adjustment component. The counterweight adjustment component drives the magnetic fixing component to move vertically along the vertical guide frame 2, tightening the fitted sheet. The counterweight adjustment component includes an inner box 9, a connecting rope 8, a main counterweight 11, an auxiliary counterweight 10, and a fixing screw 13. The inner box 9 is movably inserted into the bottom of the vertical guide frame 2. The fixing screw 13 extends from the outside of the vertical guide frame 2 and is screwed into the inner box 9. The size of the inner box 9 matches the size of the inner cavity of the vertical guide frame 2, fixing the inner box 9 to the bottom of the inner cavity of the vertical guide frame 2.

[0023] The inner box 9 has guide grooves 91 evenly spaced along the horizontal direction. Auxiliary counterweights 10 are movably inserted into the guide grooves 91 at equal intervals along the horizontal direction. The size of each guide groove 91 matches the shape of the auxiliary counterweight 10, so that the auxiliary counterweight 10 can be slidably inserted into the guide groove 91. Holes are opened on the sides of the auxiliary counterweight 10 and the main counterweight 11. The main counterweight 11 is movably inserted into the guide groove 91 located at the edge of the inner box 9. An adjustment screw 12 is screwed into the side of the main counterweight 11. One end of the adjustment screw 12 extends into the hole on the side of the auxiliary counterweight 10. The top of the main counterweight 11 is fixedly connected to one end of the connecting rope 8. The other end of the connecting rope 8 is fixedly connected to the plastic block 6. Through the multi-slot structure, the number of auxiliary counterweights 10 can be freely increased or decreased as needed to achieve different combinations of pull-down force adjustment.

[0024] It should be added that when the integrated structure of the inner fabric tape 4 and the outer fabric tape 7 is not clamping one end of the fitted sheet, the integrated structure of the inner fabric tape 4 and the outer fabric tape 7 is not at the top of the vertical guide frame 2.

[0025] The specific implementation steps and principles of this utility model are as follows: According to the actual material of the fitted sheet and the required tension, the user rotates the adjustment screw 12. One end of the adjustment screw 12 will be inserted into the auxiliary weights 10 at different positions. When the main weight 11 is pulled up by the connecting rope 8, the adjustment screw 12 will lift up different numbers of auxiliary weights 10. In use, the user lifts the adjustment screw 12 at the bottom of the connecting rope 8 to the appropriate position, inserts both ends of the fitted sheet into the paired inner and outer fabric straps 4 and 7, and uses multiple sets of opposing first magnets 41 and second magnets 71 to fix and clamp the two ends of the fitted sheet. Finally, the user releases the connecting rope 8, and the multiple auxiliary weights 10 and main weights 11 tighten the fixed fitted sheet through the connecting rope 8.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
