Description

Technical Field

[0001] This invention relates to the field of furniture technology, and in particular to a flip-up bed. Background Technology

[0002] To improve the utilization of indoor space, existing technologies have proposed folding beds with storage capabilities. Folding beds generally include a cabinet and a bed frame that is stored vertically within the cabinet. The bed frame can be folded down to a horizontal position for user use, and after use, it can be folded up to a vertical position and stored in the cabinet. In order to facilitate the user's folding down of the bed frame, handles are usually installed on the bed frame, which reduces the aesthetics of the folding bed. In addition, in order to make it easier for the user to fold down the bed frame, the handles are usually located at the top of the bed frame (here, "top" is understood based on the perspective when the bed frame is stored in the cabinet), which requires a certain height from the user and causes inconvenience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a flip-up bed with a locking structure between the bed frame and the cabinet, which can be unlocked by stepping on it. The locking structure can prevent the bed frame stored in the cabinet from flipping down. After the user unlocks the locking structure by stepping on it, the bed frame can automatically flip down to a horizontal position under its own weight. Therefore, there is no need to install handles, which improves the aesthetics of the flip-up bed. Moreover, it does not require the user's height and is convenient for the user to use.

[0004] According to an embodiment of the present invention, a flip-up bed includes: a cabinet having a receiving groove; a bed frame, the lower part of which is rotatably connected to the lower part of the cabinet, the bed frame having a storage position in a vertical state and a working position flipped down to a horizontal state, the rotation center of the bed frame being eccentrically set relative to the center of gravity of the bed frame, so that the bed frame can automatically flip down from the storage position to the working position under its own weight; and a locking structure disposed between the bottom of the cabinet and the bed frame, the locking structure having a locked state and an unlocked state, wherein when the bed frame flips up from the working position to the storage position, the locking structure can be driven to switch to the locked state, and when the locking structure is in the locked state, it can restrict the bed frame from flipping down from the storage position to the working position, wherein the locking structure has a foot pedal for a user to step on, the foot pedal being used to drive the locking structure to switch to the unlocked state.

[0005] The flip-up bed according to an embodiment of the present invention has at least the following beneficial effects: the rotation center of the bed frame is eccentrically set relative to the center of gravity of the bed frame, so that the bed frame can automatically flip down from the storage position to the working position under its own weight. At the same time, a locking structure that can be unlocked by stepping is provided between the bed frame and the cabinet. The locking structure can restrict the bed frame from flipping down from the storage position to the working position. In use, after the user unlocks the locking structure by stepping, the bed frame can automatically flip down from the storage position to the working position under its own weight. Therefore, there is no need to set handles, which helps to improve the aesthetics of the flip-up bed. Moreover, it does not require the user's height and is convenient for the user to use.

[0006] According to some embodiments of the present invention, the locking structure includes an elastic limiting member, one end of which is connected to the bottom of the cabinet, and the other end of which is suspended. The suspended end of the elastic limiting member can abut against the lower part of the bed frame when the bed frame is flipped up from the working position to the storage position, so as to restrict the bed frame from flipping down from the storage position to the working position. The stepping part is provided on the suspended part of the elastic limiting member and can drive the elastic limiting member to separate from the bed frame.

[0007] According to some embodiments of the present invention, the elastic limiting member is a metal structure, and the suspended portion of the elastic limiting member is inclined upward.

[0008] According to some embodiments of the present invention, an elastic reset member is provided between the suspended portion of the elastic limiting member and the cabinet body.

[0009] According to some embodiments of the present invention, the elastic reset member is a spring, one end of the spring is connected to the suspended portion of the elastic limiting member, and the other end of the spring is connected to the cabinet.

[0010] According to some embodiments of the present invention, one end of the elastic limiting member that is suspended is arc-shaped.

[0011] According to some embodiments of the present invention, the elastic limiting member is detachably connected to the cabinet body, and the locking structure further includes a snap-fit ​​member, which is detachably disposed at the lower part of the bed frame. The snap-fit ​​member has a vertical part and a horizontal part located in the middle or upper part of the vertical part. The lower part of the vertical part and the horizontal part enclose a slot for the suspended end of the elastic limiting member to be engaged. The suspended end of the elastic limiting member can be engaged in the slot when the bed frame is flipped from the working position to the storage position, thereby restricting the bed frame from flipping down from the storage position to the working position. The stepping part can drive the suspended end of the elastic limiting member to disengage from the slot.

[0012] According to some embodiments of the present invention, a flexible protective pad is provided in the slot corresponding to the elastic limiting member.

[0032] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0033] The specific structure of the flip-up bed according to the embodiment of the present invention will be described in detail below. The directions such as up, down, top, bottom, inside, and outside mentioned in the following description should be understood based on the perspective when the bed frame of the flip-up bed is stored in the cabinet. At the same time, these directions are based on the markings in the accompanying drawings.

[0034] Reference Figure 1 , Figure 2 , Figure 5 and Figure 8The flip-up bed according to an embodiment of the present invention includes a cabinet 100, a bed frame 200, and a locking structure.

[0035] The cabinet 100 has a receiving slot 110. The lower part of the bed frame 200 is rotatably connected to the lower part of the cabinet 100. The bed frame 200 has a storage position where it is stored in the receiving slot 110 and is in a vertical state, and a working position where it is tilted down relative to the cabinet 100 and is in a horizontal state. The rotation center of the bed frame 200 is eccentrically set relative to the center of gravity of the bed frame 200. Specifically, when the bed frame 200 is in the storage position, the center of gravity of the bed frame 200 is located above and outside the rotation center of the bed frame 200, so that the bed frame 200 can automatically move from the storage position to the horizontal position under its own weight. When the cabinet 100 is folded down to the working position, there is a gap between the bottom of the cabinet 100 and the ground. A locking structure is set between the bottom of the cabinet 100 and the bed frame 200. The locking structure has a locked state and an unlocked state. When the bed frame 200 is folded up from the working position relative to the cabinet 100 to the storage position, it can drive the locking structure to switch to the locked state. When the locking structure is in the locked state, it can prevent the bed frame 200 from folding down from the storage position relative to the cabinet 100 to the working position. The locking structure has a foot pedal 310 for the user to step on. The foot pedal 310 is used to drive the locking structure to switch to the unlocked state.

[0036] The rotation center of the bed frame 200 is offset from its center of gravity, allowing it to automatically fold down from its storage position relative to the cabinet 100 to its working position under its own weight. A locking mechanism, which can be unlocked by stepping on the bed frame 200 and the cabinet 100, prevents the bed frame 200 from folding down relative to the cabinet 100. In use, the user unlocks the locking mechanism by stepping on the bed frame 200, allowing it to automatically fold down from its storage position relative to the cabinet 100 to its working position under its own weight. Therefore, no handles are needed, improving the aesthetics of the folding bed and making it convenient for users of all heights.

[0037] Reference Figures 2 to 7In some embodiments, the locking structure includes an elastic limiting member 300, one end of which is connected to the bottom of the cabinet 100, and the other end of which is suspended. The suspended end of the elastic limiting member 300 can abut against the lower part of the bed frame 200 when the bed frame 200 is flipped up relative to the cabinet 100 from the working position to the storage position. Specifically, it abuts against the area below the rotation center of the bed frame 200 to restrict the bed frame 200 from flipping down relative to the cabinet 100 from the storage position to the working position. A foot pedal 310 is provided on the suspended part of the elastic limiting member 300 and can drive the elastic limiting member 300 to separate from the bed frame 200. When the bed frame 200 flips up from the working position relative to the cabinet 100 to the storage position, the end of the elastic limiting member 300 that is suspended in the air abuts against the lower part of the bed frame 200 to prevent the bed frame 200 from flipping down from the storage position relative to the cabinet 100 to the working position. When the user steps on the foot pedal 310, it can drive the end of the elastic limiting member 300 that is suspended in the air to separate from the bed frame 200. At this time, the bed frame 200 can automatically flip down from the storage position relative to the cabinet 100 to the working position under its own weight. Its structure is simple and easy to operate.

[0038] Reference Figure 3 , Figure 6 and Figure 9 In some embodiments, the elastic limiting member 300 is a metal structure, which helps to improve the structural strength of the elastic limiting member 300 and thus extend its service life. The suspended portion of the elastic limiting member 300 is inclined upwards to prevent deformation of the suspended portion due to repeated stress during use, thereby preventing failure of the elastic limiting member 300. Specifically, the upward inclination angle α of the suspended portion of the elastic limiting member 300 is 17° to 20°.

[0039] It should be noted that in some embodiments, an elastic reset member is provided between the suspended part of the elastic limit member 300 and the cabinet 100. The elastic reset member can assist the elastic limit member 300 in resetting, which helps to further prevent the suspended part of the elastic limit member 300 from deforming due to repeated force during use.

[0040] Reference Figure 3 , Figure 6 and Figure 9 In some embodiments, the elastic reset element is a spring 400, one end of which is connected to the suspended part of the elastic limiting element 300, and the other end of which is connected to the cabinet 100. Its structure is simple and easy to implement.

[0041] It should be noted that in some other embodiments, the elastic reset member may also be a rubber band or other elastic structure connected between the suspended part of the elastic limiting member 300 and the cabinet 100, which is not limited here.

[0042] Reference Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 9 In some embodiments, the end of the elastic limiting member 300 that is suspended is arc-shaped and has a guiding function, making the switching between the locked and unlocked states of the locking structure smoother.

[0043] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the elastic limiting member 300 is detachably connected to the cabinet 100. The locking structure also includes a snap-fit ​​member 500, which is detachably disposed at the lower part of the bed frame 200. Specifically, the snap-fit ​​member 500 is located below the rotation center of the bed frame 200. The snap-fit ​​member 500 has a vertical portion 510 and a horizontal portion 520 located in the middle or upper part of the vertical portion 510. The lower part of the vertical portion 510 and the horizontal portion 520 enclose a slot 530 for the suspended end of the elastic limiting member 300 to be snapped into. The suspended end of the elastic limiting member 300 can be snapped into the slot 530 when the bed frame 200 is flipped up from the working position relative to the cabinet 100 to the storage position, so as to restrict the bed frame 200 from the storage position relative to the cabinet 100 to the working position. The stepping part 310 can drive the suspended end of the elastic limiting member 300 to disengage from the slot 530. When the bed frame 200 is flipped up from the working position relative to the cabinet 100 to the storage position, the suspended end of the elastic limiting member 300 can be engaged in the slot 530 to prevent the bed frame 200 from flipping down from the storage position relative to the cabinet 100 to the working position. When the user steps on the foot pedal 310, the suspended end of the elastic limiting member 300 can be disengaged from the slot 530. At this time, the bed frame 200 can automatically flip down from the storage position relative to the cabinet 100 to the working position under its own weight. The elastic limiting member 300 is detachably connected to the cabinet 100, and the locking member 500 is detachably set at the lower part of the bed frame 200. When the locking structure fails, it is convenient to repair or replace the elastic limiting member 300 and / or the locking member 500.

[0044] Reference Figure 4 and Figure 7In some embodiments, a flexible protective pad 540 is provided in the slot 530 corresponding to the elastic limiting member 300, which helps to reduce wear between the elastic limiting member 300 and the snap-fit ​​member 500, and also helps to reduce the noise generated by friction between the elastic limiting member 300 and the snap-fit ​​member 500. Specifically, the flexible protective pad 540 is a velvet protective pad. Of course, the flexible protective pad 540 can also be a cotton protective pad or a protective pad made of other flexible materials, which is not limited here.

[0045] Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the bottom of the vertical part 510 protrudes from the bottom of the bed frame 200. The bottom of the vertical part 510 is provided with a roller 550 corresponding to the elastic limiting member 300, so that the end of the elastic limiting member 300 suspended in the air can be more smoothly inserted into the slot 530 when the bed frame 200 is flipped up from the working position relative to the cabinet 100 to the storage position. Specifically, the roller 550 is made of plastic. Of course, the roller 550 can also be made of rubber, which is not limited here.

[0046] Reference Figure 2 , Figure 5 and Figure 8 In some embodiments, a limiting stop 600 is provided in the receiving slot 110 corresponding to the upper part of the bed frame 200. When the user applies force to the bed frame 200 to flip it upwards relative to the cabinet 100 from the working position to the storage position, it helps prevent the bed frame 200 from rotating excessively due to inertia. This helps prevent the bed frame 200 stored in the receiving slot 110 of the cabinet 100 from tilting inwards, thereby ensuring that when the locking structure is switched to the unlocked state, the bed frame 200 can automatically flip downwards relative to the cabinet 100 from the storage position to the working position under its own gravity. Specifically, the limiting stop 600 is a metal structure, which makes it less prone to deformation during use, thus improving the reliability of the limiting stop 600.

[0047] Reference Figure 2 , Figure 5 and Figure 8 In some embodiments, a gas spring 700 for providing cushioning force is provided between the side panel of the cabinet 100 and the bed frame 200, and a foldable support leg 210 is provided on the upper part of the bed frame 200. The gas spring 700 and the support leg 210 are well known technologies in the art, and their specific structures, settings and working principles will not be described in detail here.

[0048] It should be noted that, in order to prevent interference between the bed frame 200 and the cabinet 100 during rotation, the position of the elastic reset member needs to be limited when setting it. Specifically, when the bed frame 200 is not equipped with the aforementioned latching member 500, it is necessary to ensure that the bottom of the bed frame 200 does not interfere with the elastic reset member, that is, the movement trajectory of the bottom of the bed frame 200 does not intersect with the movement trajectory of the elastic reset member. Specifically, it is necessary to ensure that the minimum distance between the bottom of the bed frame 200 and the elastic reset member is greater than zero. When the bed frame 200 is equipped with the aforementioned latching member 500, it is necessary to ensure that the bottom of the vertical part 510 and the roller 550 do not interfere with the elastic reset member, that is, the movement trajectory of the bottom of the vertical part 510 and the roller 550 does not intersect with the movement trajectory of the elastic reset member. Specifically, the elastic reset member and the latching member 500 are offset so that the elastic reset member avoids the latching member 500.

[0049] It should be noted that in some other embodiments, the locking structure may also be a magnetic structure located between the lower part of the cabinet 100 and the bed frame 200 and can be unlocked by stepping on it, which is not limited here.
