[0028] See also Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a multi-angle adjustable bed frame provided by an embodiment of the present invention; Figure 2 This is a schematic diagram of the top structure of a multi-angle adjustable bed frame provided by one embodiment of the present invention.
[0029] To address the technical issue of the conventional bed rest adjustment process, which can easily lead to user injury, or to achieve at least one of the aforementioned advantages or other advantages, one embodiment of the present invention provides a multi-angle adjustable bed frame. As shown in the figure, the multi-angle adjustable bed frame includes a first bed frame 10 and a second bed frame 20. The area of the second bed frame 20 is smaller than that of the first bed frame 10.
[0030] Specifically, a gap 30 is provided between the four edges of the second bed frame 20 and the first bed frame 10. By providing the gap 30 between the first and second bed frames 10, the gap 30 provides space for the user's hands when adjusting the angle of the second bed frame 20. This not only facilitates the user's grip on the second bed frame 20 to adjust the angle, but also prevents the user's hands from being pinched by the first and second bed frames 10, 20, improving user safety. Furthermore, the gap 30 provides storage space, reducing the space occupied by the multi-angle adjustable bed frame when stored.
[0031] Please combine Figure 1 、 Figure 2 See Figure 3 、 Figure 4 and Figure 5As shown in the figure, the first bed frame 10 is a three-section foldable bed frame. Specifically, the first bed frame 10 includes a first section 11, a second section 12, a third section 13, a first connector 14, and a second connector 15. The second section 12 is located in the middle, with the first section 11 and the third section 13 located at either end of the second section 12. The first section 11 is hingedly connected to the second section 12 via the first connector 14. The third section 13 is hingedly connected to the second section 12 via the second connector 15.
[0032] In a specific implementation, the first connecting member 14 and the second connecting member 15 allow the first portion 11, the third portion 13, and the second portion 12 to be folded together to form a stowed state, thereby reducing space usage. Preferably, the length of the first connecting member 14 is greater than the length of the second connecting member 15, so that in the stowed state, the third portion 13 is positioned above the second portion 12, and the first portion 11 is positioned above the third portion 13, forming a stacked state, further reducing space usage.
[0033] In addition to the above, the first bed frame 10 further includes multiple pairs of legs 16. These pairs of legs 16 are respectively disposed at the bottom of the first portion 11, the third portion 13, the first connector 14, and the second connector 15. Specifically, there are four pairs of legs 16, disposed at the bottom of the end of the first portion 11 away from the second portion 12, the bottom of the end of the third portion 13 away from the second portion 12, the bottom of the first connector 14, and the bottom of the second connector 15. Two pairs of legs 16 are rotatably connected to the first portion 11 and the third portion 13. This means that the legs 16 can be rotated to a position parallel to the first bed frame 10 for storage, facilitating folding of the first bed frame 10 and reducing space usage.
[0034] The other two pairs of bed legs 16 are fixedly connected to the first connecting member 14 and the second connecting member 15. When the first bed frame 10 is stored, since the two ends of the first connecting member 14 are hinged to the first part 11 and the second part 12 respectively, and the second connecting member 15 is hinged to the third part 13 and the second part 12 respectively, during the folding process, the first connecting member 14 and the second connecting member 15 can rotate synchronously, thereby driving the bed legs 16 connected to the first connecting member 14 and the second connecting member 15 to rotate until the two pairs of bed legs 16 are in contact with or parallel to the second part 12. At this time, based on the first connecting member 14 and the second connecting member 15, the first part 11 and the third part 13 can continue to rotate and fold, eventually forming a stacked state with the third part 13 above the second part 12 and the first part 11 above the third part 13, thereby reducing space occupation.
[0035] like Figure 5As shown, during the unfolding process, as the first part 11 and the third part 13 unfold, the two pairs of bed legs 16 connected to the first connecting member 14 and the second connecting member 15 will automatically unfold to a state perpendicular to the first bed frame 10, reducing the assembly steps for unfolding.
[0036] Furthermore, the first bed frame 10 includes several supports 17. These supports 17 are rotatably disposed on the first portion 11, the second portion 12, and the third portion 13. In the stowed state, the supports 17 are rotated into the first bed frame 10 for storage. In the deployed state, the other ends of the supports 17 are secured to the bed legs 16 via fasteners 18, forming a triangular structure between the first portion 11, the second portion 12, the third portion 13, and the bed legs 16. This improves the support and stability of the bed legs 16, thereby enhancing the overall stability of the first bed frame 10. Preferably, the fasteners 18 are thumb screws.
[0037] When the first bed frame 10 needs to be used, the first part 11 and the third part 13 can be opened in sequence, and the bed legs 16 on the first part 11 and the third part 13 can be rotated to a vertical state. At this time, the other ends of the several support members 17 are fixed to the first part 11, the second part 12 and the third part 13 respectively by fasteners 18, and the bed legs 16 are fixed so that the bed legs 16 can provide stable support for the first bed frame 10.
[0038] Please combine Figure 1 、 Figure 2 See Figure 6 As shown in the figure, the second bed frame 20 includes a first component 21, a second component 22, a third component 23, and a fourth component 24. The first component 21, the second component 22, the third component 23, and the fourth component 24 are sequentially arranged on the first bed frame 10. The first component 21, the third component 23, and the fourth component 24 are each movably connected to the first bed frame 10, while the second component 22 is fixedly connected to the first bed frame 10.
[0039] In practice, the second bed frame 20 also includes a plurality of multi-level adjustable locking mechanisms 25. The end of the first component 21 proximate to the second component 22 is movably connected to the first bed frame 10 via the multi-level adjustable locking mechanisms 25. The end of the third component 23 proximate to the second component 22 is movably connected to the first bed frame 10 via the multi-level adjustable locking mechanisms 25. Specifically, the multi-level adjustable locking mechanisms 25 are ratchet hinges. The multi-level adjustable locking mechanisms 25 enable the first and third components 21, 23 to be adjusted at multiple angles, providing a variety of angles to accommodate different user habits or usage scenarios, thereby enhancing the practicality of the multi-angle adjustable bed frame.
[0040] Preferably, if Figure 7As shown, the multi-stage adjustment locking mechanism 25 is a pneumatic rod, which can provide assistance in the process of adjusting the angles of the first component 21 and the third component 23, and can more easily achieve multi-angle adjustment of the first component 21 and the third component 23.
[0041] Furthermore, the other end of the third component 23 is movably connected to the fourth component 24. Specifically, the other end of the third component 23 is hingedly connected to the fourth component 24, meaning that the fourth component 24 can rotate relative to the third component 23, and the direction of rotation of the fourth component 24 relative to the third component 23 is opposite to the direction of rotation of the third component 23 relative to the first bed frame 10. During use, after adjusting the first and third components 21, 23 to a suitable angle, the fourth component 24 can be adjusted to a suitable footrest angle to enhance comfort.
[0042] Building on the above, the end of the fourth assembly 24, distal from the third assembly 23, is movably connected to the first bed frame 10 via a third connector 26. Specifically, the ends of the third connector 26 are hingedly connected to the first bed frame 10 and the fourth assembly 24, respectively, providing support for the fourth assembly 24. When stowed, the third connector 26 can be stored in the gap 30, reducing space usage.
[0043] In some preferred embodiments, the second bed frame 20 further includes a plurality of spokes 27. The spokes 27 are spaced apart and arranged on the first component 21, the second component 22, the third component 23 and the fourth component 24 to improve the uniformity of the force applied to the second bed frame 20.
[0044] In some preferred embodiments, the second bed frame 20 further includes a plurality of stoppers 28 . These stoppers 28 are disposed on the first component 21 , the third component 23 , and the fourth component 24 . Specifically, there are five stoppers 28 , located on the left and right sides of the first component 21 , the left and right sides of the third component 23 , and the end of the fourth component 24 facing away from the third component 23 . When a mattress is placed on the second bed frame 20 , the stoppers 28 secure the mattress, preventing it from shifting during adjustment of the angles of the first, third, and fourth components 21 , 23 , and 24 .
[0045] Furthermore, the five limiting portions 28 protrude from the first component 21, the third component 23 and the fourth component 24 in height and protrude from the first bed frame 10 in width, so that the user can adjust the angles of the first component 21, the third component 23 and the fourth component 24 by grabbing the limiting portions 28, which is not only convenient for use but also can avoid pinching the user's hands.
[0046] In some preferred embodiments, the multi-angle adjustable bed frame further includes two load-bearing sections 40, one located at the front and rear ends of the first bed frame 10. When the second bed frame 20 is in a flat position, the two load-bearing sections 40 of the first assembly 21 and the fourth assembly 24 are connected to each other. The two load-bearing sections 40 provide upward support for the first assembly 21 and the fourth assembly 24, respectively, thereby increasing the load-bearing capacity of the second bed frame.
[0047] To sum up, the multi-angle adjustable bed frame provided by the present invention is different from the prior art in that a gap 30 is provided between the first bed frame 10 and the second bed frame 20. When the user adjusts the angle of the second bed frame 20, the gap 30 can provide operating space for the user's hands, which not only makes it convenient for the user to grab the second bed frame 20 and adjust the angle, but also prevents the first bed frame 10 and the second bed frame 20 from pinching the user's hands, thereby improving safety in use. In addition, the gap 30 can provide storage space, reducing the space occupied by the multi-angle adjustable bed frame in the stored state, thereby greatly improving convenience and practicality in use.
[0048] Although terms such as spokes and limiters are frequently used in this document, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the present invention; interpreting them as any additional restrictions is contrary to the spirit of the present invention.
[0049] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the present invention may be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background art at the same time. Those skilled in the art should understand that the absence of any content in a claim should not be construed as a limitation on that claim.
[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
