Description

Technical Field

[0001] This utility model relates to the field of everyday bedding technology, specifically a multifunctional bed that prevents mattress slippage. Background Technology

[0002] Mattress slippage is a long-standing problem that plagues users during bed use, stemming from fundamental flaws in traditional anti-slip design. Existing bed frames primarily rely on two methods to limit mattress movement: one is utilizing the natural friction between the mattress and the bed frame surface, and the other is installing simple guardrails along the edges of the bed frame.

[0003] From a mechanical perspective, the movements of a person turning over or getting up on a bed generate lateral thrust. When this thrust exceeds the maximum static friction between the mattress and the bed frame, the mattress will inevitably slide. Experimental data shows that the coefficient of friction between a typical mattress and a wooden bed frame is approximately 0.3-0.4. If the mattress weighs 5kg, only a lateral force of 15-20N is needed to overcome the friction constraint (calculated using the friction formula f=μN). However, the lateral force generated by an adult turning over can reach 30-50N, far exceeding the critical value, making sliding inevitable.

[0004] On the other hand, existing mattress support structures have design flaws: most support strips are only 1-2cm high, meaning that for conventional mattresses thicker than 10cm, the support strips can only contact the bottom edge of the mattress, failing to provide effective protection; furthermore, the support strips are often fixed with a single screw, which can easily loosen and tilt under long-term stress, further losing their limiting function. This design flaw directly leads to two major problems: first, the mattress frequently shifts during sleep, requiring repeated adjustments and severely affecting sleep continuity; second, the continuous friction between the mattress edge and the support strips and bed board causes fabric wear and exposure of the internal filling, significantly shortening the mattress's lifespan.

[0005] Therefore, how to construct an anti-slip structure that can effectively resist lateral thrust and adapt to mattresses of different thicknesses has become a key issue that urgently needs to be addressed in bed design. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a multifunctional bed that prevents mattresses from slipping, solving the problems that existing bed frames cannot resist lateral thrust and cannot adapt to mattresses of different thicknesses.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional bed with anti-slip mattress, comprising bed legs, a bed frame and a connecting frame, wherein bolts are threaded onto the outer surface of the bed legs, and connecting holes are provided on the outer surface of the bed frame and the connecting frame, and the bed legs are connected to the connecting holes on the bed frame and the connecting frame by means of bolts; multiple grooves are provided on the upper surface of the bed frame.

[0008] The groove is fixedly connected to the bed board by bolts;

[0009] The outer surfaces of the bed legs, bed frame, and connecting frame are all provided with protruding bed frame edges, and the lower surface of the bed legs is integrally formed with a leg rod;

[0010] The outrigger rod is equipped with a protective device inside. The protective device includes a connecting groove inside the outrigger rod, and a T-shaped buffer pad is fixedly connected to the inner wall of the connecting groove.

[0011] Preferably, the inner wall of the buffer pad is provided with an inverted trapezoidal expansion groove, the lower surface of the buffer pad is integrally formed with a wear-resistant block, and the outer surfaces of both the buffer pad and the wear-resistant block are coated with a wear-resistant layer; a soft pad is fixedly connected to the upper surface of the bed support leg.

[0012] The protruding height of the bed frame is 3-5cm, and it forms a closed structure around the edge of the bed frame and connecting frame.

[0013] Preferably, the groove is rectangular and the distance between adjacent grooves is 20-30cm, and the edge of the bed board fits against the inner wall of the groove.

[0014] Preferably, the diameter of the connecting hole is 8-10mm, and the connecting holes on the bed frame and the connecting frame are symmetrically distributed.

[0015] Preferably, the buffer pad is made of rubber or silicone material, and the transverse part of its T-shaped structure is interference-fitted with the inner wall of the connecting groove. The interference fit means that the transverse part is larger than the inside of the connecting groove.

[0016] Preferably, the depth of the expansion groove is 1 / 3 to 1 / 2 of the thickness of the buffer pad, and the width of the groove opening is less than the width of the groove bottom.

[0017] Preferably, the wear-resistant layer is a polyurethane coating with a thickness of 0.5-1mm, and it uniformly covers the outer surface of the buffer pad and the wear-resistant block.

[0018] Preferably, the thickness of the cushion is 5-8cm, and the upper surface is provided with anti-slip texture, and it is at the same level as the upper surface of the bed board.

[0020] This multi-functional bed with anti-slip design features a raised frame structure formed by the protruding edges of the bed frame, connecting frame, and bed legs. When the mattress is placed on the bed board, the frame can prevent the mattress from sliding sideways during lateral movement. Especially under the pushing force generated by actions such as turning over or getting up, the mattress is prevented from shifting through rigid restraint. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a new technical solution: a multi-functional bed that prevents mattress side slippage, including bed legs 1, bed frame 2 and connecting frame 12. The outer surface of the bed legs 1 is threaded with bolts, the outer surface of the bed frame 2 is provided with connecting holes 4, and the outer surface of the connecting frame 12 is provided with the same connecting holes 4. The bed legs 1 are connected to the bed frame 2 and the connecting frame 12 by bolts.

[0029] The upper surface of the bed frame 2 has multiple grooves 3, and the outer surface of the grooves 3 is fixedly connected to the bed board 6 by bolts. The outer surface of the bed legs 1 has a protruding bed frame, and the outer surfaces of the bed frame 2 and the connecting frame 12 also have a protruding bed frame. This special protruding structure can prevent the mattress from slipping after it is placed on it. The lower surface of the bed legs 1 has an integrally formed support rod 5, and the support rod 5 has a protective device inside.

[0030] Furthermore, the protective device includes a connecting groove 7, which is opened inside the support leg 5. A buffer pad 8 is fixedly connected to the inner wall of the connecting groove 7. The buffer pad 8 is T-shaped. An expansion groove 9 is opened on the inner wall of the buffer pad 8. The expansion groove 9 is inverted trapezoidal. A wear-resistant block 11 is integrally formed on the lower surface of the buffer pad 8. A wear-resistant layer 10 is sprayed on the outer surface of the buffer pad 8. A wear-resistant layer 10 is also sprayed on the outer surface of the wear-resistant block 11. A soft pad 13 is fixedly connected to the upper surface of 1.

[0031] Furthermore, when using the device, the protruding edge of the bed frame 2, the connecting frame 12 and the bed support leg 1 forms a surrounding raised structure. When the mattress is placed on the bed board 6, the edge can prevent the mattress from sliding sideways when it moves laterally. Especially under the pushing force generated by actions such as turning over and getting up, the mattress is prevented from shifting by rigid limiting.

[0032] The bed board 6 is rigidly connected to the bed frame 2 through the groove 3, forming a flat and stable load-bearing surface. The friction between the mattress and the bed board, combined with the blocking effect of the frame, constructs a dual anti-slip system of "friction + barrier", solving the problem of traditional bed frames relying solely on friction and easily slipping.

[0033] Furthermore, when the device is used, when the bed is subjected to pressure (such as when a person is lying down or jumping), the buffer pad 8 (T-shaped structure) inside the support leg 5 is deformed by pressure, and the inverted trapezoidal expansion groove 9 on its inner wall contracts accordingly. The impact force is absorbed through material deformation, reducing the transmission of vibration to other parts of the bed.

[0034] When the wear-resistant block 11 comes into contact with the ground, the wear-resistant layer 10 on the surface can reduce wear caused by long-term use, while the elastic support of the buffer pad 8 can reduce hard collisions between the bed and the ground, extending the overall service life of the bed.

[0035] Furthermore, when using this device, modular assembly is possible: by using the bolts of the bed legs 1 to engage with the connecting holes 4 of the bed frame 2 and the connecting frame 12, different sizes of bed frames (such as single beds and double beds) can be flexibly assembled to meet the needs of diverse usage scenarios.

[0036] Easy disassembly and maintenance: All components are connected by bolts. Disassembly can be carried out by simply loosening the bolts, which facilitates transportation, storage and component replacement, and solves the problems of cumbersome assembly and inconvenient maintenance of traditional bed frames.
