[0002] Iron bunk beds have many advantages, such as simple construction, durability, easy cleaning, and low cost, and are widely used in daily life.

[0003] Existing iron bunk beds are usually fixed, using bolts or welding to form a fixed structure, which is extremely inconvenient for actual transportation; the large size of iron bunk beds is also not convenient for storage, folding or moving.

[0004] In addition, iron frame beds used as children's beds have a fixed structure, and the headboard and footboard cannot be opened, making it difficult to easily pick up or put down young children. Utility Model Content

[0005] To address the aforementioned issues, this application provides a structurally sound, installation-free, and foldable bed that can be quickly and easily folded or unfolded, effectively enhancing the user experience and offering high flexibility.

[0006] The technical solution adopted in this utility model is as follows: A foldable bed that requires no installation includes a guardrail and a bed frame rotatably mounted on the lower edge of the guardrail. The bed frame can be flipped upwards relative to the guardrail to a folded state or flipped downwards to a usable state. A flip frame is installed on one or both sides of the guardrail. The flip frame can be flipped relative to the guardrail to form three states: usable, open, and folded. The flip frame is attached to the bed frame to form the usable state. The flip frame is flipped outwards away from the guardrail to open from the usable state. The flip frame is flipped inwards towards the guardrail to fold from the usable state.

[0007] As a further improvement to the above technical solution: The lower edge of the guardrail is rotatably connected to the bed frame via a rotating component, which is either a pivot structure or a hinge structure.

[0008] The lower edge of the guardrail is fitted with corner brackets along its length. When the bed frame is flipped downwards relative to the guardrail to the use position, the corner brackets provide support for the bed frame.

[0009] The corner piece has an L-shaped structure. The outer wall of the vertical wall of the corner piece is fitted to the inner side of the lower part of the guardrail. The bed frame is flipped downward relative to the guardrail and supported on the top surface of the horizontal arm of the corner piece.

[0010] A fixed frame is installed at the side edge of the guardrail, and a flip frame is rotatably installed on the fixed frame to form the frame body at the end of the bed; the flip frame is arranged vertically relative to the rotation axis of the fixed frame.

[0011] The upper and lower ends of the fixed frame extend toward the flipping frame to form a joint one, and the upper and lower ends of the flipping frame extend toward the fixed frame to form a joint two. The upper joint one and joint two are jointly installed with a shaft pin, and the lower joint one and joint two are jointly installed with another shaft pin arranged coaxially.

[0012] The fixing frame is arranged perpendicular to the guardrail, and the dimension of the fixing frame in the direction perpendicular to the guardrail is greater than the thickness of the bed frame; when the bed frame and the flip frame are both facing the guardrail and in a folded state, the bed frame is located between the guardrail and the flip frame.

[0013] One of the flip-up frame and the bed frame is equipped with a push-button lock, and the other is equipped with a locking device that engages with the push-button lock, forming a locking structure that can be quickly opened and closed; the locking structure is located at the end of the flip-up frame away from the guardrail.

[0014] A push-button lock is installed on the inner side of the end of the flip frame, and a locking component that matches the push-button lock is installed on the edge of the bed frame; the locking component extends toward the flip frame and forms a limiting wall, and a locking space for accommodating the push-button lock tongue is formed on the inner side of the limiting wall.

[0015] The bottom of the bed frame away from the guardrail is foldable and has a support leg 1 installed. The bottom of the guardrail is downward and has a support leg 2 installed. The bed in the unfolded use state is supported by support leg 1 and support leg 2. Support leg 1 is folded and close to the bed frame. Support leg 1 and support leg 2 are fixed length structures or length adjustable structures.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model's bed frame and flip-up frame can be quickly unfolded relative to the guardrail to achieve a usable state without the need for external tools for installation, achieving installation-free use; the flip-up frame can be closed relative to the bed frame to serve as a protective fence, or it can be opened to facilitate picking up or putting down young children; the bed frame and flip-up frame can also be flipped towards the guardrail to form a folded state, facilitating the storage, folding, moving, and transportation of the bed, effectively improving the user's actual user experience and providing high flexibility in use; This utility model also has the following advantages: A flip-up frame can be installed on one side of the guardrail to form a double-sided protective bed, or flip-up frames can be installed on both sides of the guardrail to form a three-sided protective bed. This utility model can be a metal frame bed or a bed made of wood or other materials. It can quickly unfold and fold the bed frame and flip-up frame relative to the guardrail to meet actual usage needs. When in use, the flip-up frame can be locked relative to the bed frame via a button lock to maintain its protective function during use; when it is necessary to open the flip-up frame, force can be applied to the button lock to unlock it for easy operation.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0032] like Figure 1 , Figure 2 and Figure 6 As shown, this embodiment of a foldable bed that requires no installation includes a guardrail 2. A bed frame 1 is rotatably mounted on the lower edge of the guardrail 2. The bed frame 1 can be flipped upwards relative to the guardrail 2 to a folded state or flipped downwards to a usable state. A flip frame 32 is installed on one or both sides of the guardrail 2. The flip frame 32 can be flipped relative to the guardrail 2 to form three states: usable, open, and folded. The flip frame 32 is attached to the bed frame 1 to form the usable state. The flip frame 32 is flipped outwards away from the guardrail 2 to open from the usable state. The flip frame 32 is flipped inwards towards the guardrail 2 to fold from the usable state.

[0033] In this embodiment, the bed frame 1 and the flip-up frame 32 can be quickly unfolded relative to the guardrail 2 to form a usable state without the need for external tools for installation, thus achieving installation-free use; the flip-up frame 32 can be closed relative to the bed frame 1 to serve as a protective fence, or it can be opened to facilitate picking up or putting down a child; the bed frame 1 and the flip-up frame 32 can also be flipped towards the guardrail 2 to form a folded state, so as to facilitate the storage, folding, moving, and transportation of the bed.

[0034] The lower edge of the guardrail 2 is rotatably connected to the bed frame 1 via a rotating component 6, which is either a pivot structure or a hinge structure.

[0035] In this embodiment, when the rotating component 6 is a rotating shaft structure, one or more coaxial rotating shafts can be arranged at intervals along the length direction of the lower edge of the guardrail 2, and bushings matching the rotating shaft set are provided on the edge of the bed frame 1 to form a rotating structure; of course, in actual operation, the rotating shaft can also be set on the bed frame 1, and the bushing matching the rotating shaft can be set on the guardrail 2, which can also form a rotating structure between the bed frame 1 and the guardrail 2.

[0036] In this embodiment, the rotating component 6 can be a hinge structure. The two relatively rotating pieces of the hinge structure are respectively installed on the guardrail 2 and the bed frame 1 to form a rotating structure. In actual operation, according to actual needs, two or more hinges with the same rotation axis can be arranged at intervals along the length direction of the guardrail 2 and the bed frame 1.

[0037] Corner brackets 7 are installed along the length of the lower edge of the guardrail 2. When the bed frame 1 is flipped down relative to the guardrail 2 to the use state, the corner brackets 7 provide support for the bed frame 1, ensuring the structural reliability and stability of the bed frame 1 when it is unfolded relative to the guardrail 2.

[0038] In this embodiment, the corner piece 7 can limit the position of the bed frame 1 relative to the guardrail 2, thereby reducing or even avoiding the force on the rotating structure between the guardrail 2 and the bed frame 1, and ensuring the smooth and unobstructed relative rotation.

[0039] exist Figure 3 In the embodiment shown, the corner piece 7 has an L-shaped structure. The outer wall of the vertical wall of the corner piece 7 is fitted and installed on the lower inner side of the guardrail 2. After the bed frame 1 is flipped downward relative to the guardrail 2, it is supported on the top surface of the horizontal arm of the corner piece 7. The top surface of the corner piece 7 forms the support for the bed frame 1 in the unfolded state.

[0040] A fixing frame 31 is installed at the edge of the guardrail 2, and a flip frame 32 is rotatably mounted on the fixing frame 31, forming the frame body 3 at the end of the bed; the flip frame 32 is arranged vertically relative to the rotation axis of the fixing frame 31, such as Figure 3 As shown.

[0041] In this embodiment, force can be applied to the flipping frame 32 to make it rotate inward or outward relative to the fixed frame 31 along the vertical axis, thereby switching between the use state and the folded state.

[0042] In this embodiment, the dimensions of the flip frame 32 and the fixed frame 31 can be set according to actual design and usage requirements to facilitate actual use, while also taking into account the size of the bed in the folded state.

[0043] The upper and lower ends of the fixed frame 31 extend toward the flipping frame 32 to form a first joint 33, and the upper and lower ends of the flipping frame 32 extend toward the fixed frame 31 to form a second joint 34. The upper joint 33 and the second joint 34 are jointly installed with a shaft pin, and the lower joint 33 and the second joint 34 are jointly installed with another shaft pin arranged coaxially. Thus, the rotation of the flipping frame 32 relative to the fixed frame 31 is realized by the combination of the first joint 33, the second joint 34 and the shaft pin.

[0044] In actual operation, the flipping frame 32 and the fixed frame 31 can also be set to other conventional rotating structures, as long as they can meet the state switching of the flipping frame 32.

[0045] The fixing frame 31 is arranged perpendicular to the guardrail 2, and the dimension of the fixing frame 31 in the direction perpendicular to the guardrail 2 is greater than the thickness dimension of the bed frame 1; when the bed frame 1 and the flip frame 32 are both facing the guardrail 2 and in a folded state, the bed frame 1 is located between the guardrail 2 and the flip frame 32.

[0046] In this embodiment, by limiting the corresponding dimensions of the fixing frame 31 and the thickness of the bed frame 1, the thickness of the guardrail 2 in the folded state is minimized while satisfying the folding requirement.

[0047] like Figure 4 and Figure 5 As shown, a push-button lock 8 is installed on one of the flip frame 32 and the bed frame 1, and a locking piece 80 that is fitted and locked to the push-button lock 8 is installed on the other, forming a locking structure that can be quickly opened and closed.

[0048] In this embodiment, the flip-up frame 32 can be locked relative to the bed frame 1 via the button lock 8 when in use, so that the position of the flip-up frame 32 relative to the bed frame 1 is fixed and the protective function is maintained during use; when it is necessary to open the flip-up frame 32, force can be applied to the button lock 8 to unlock it, which is convenient for operation.

[0049] The locking structure is located at the end of the tilting frame 32 away from the guardrail 2, which effectively ensures the reliability of the overall structure when the tilting frame 32 is locked relative to the bed frame 1 via the locking structure.

[0050] A push-button lock 8 is installed on the inner side of the end of the flip frame 32, and a locking piece 80 that matches the push-button lock 8 is installed on the edge of the bed frame 1. When the bed frame 1 is in the unfolded state and the flip frame 32 is rotated toward the bed frame 1 under force, it can be locked by the push-button lock 8 on the inner side of the flip frame 32 and the locking piece 80 of the bed frame 1 along the direction of rotation when the flip frame 32 approaches and contacts the bed frame 1, which is convenient for operation.

[0051] In actual operation, the button lock 8, which is installed inside the tilting frame 32, has a button 84 that can pass through the tilting frame 32 and face outwards, such as... Figure 5 As shown, this facilitates the application of force in practice.

[0052] The locking member 80 extends toward the flip frame 32 and forms a limiting wall 800. A locking space is formed inside the limiting wall 800 to accommodate the downward extension of the bolt 86 of the push button lock 8, thereby locking the bolt 86 in the extended state relative to the locking member 80.

[0053] When unlocking, force is applied to the button lock 8, causing the bolt 86 to retract upward and disengage from the locking space of the lock member 80, thus unlocking the device.

[0054] The push-button lock 8 in this embodiment, also known as an impact lock, can be a conventional commercially available standard product. When force is applied to the force-bearing part, the locking tongue switches between extended and retracted states to achieve locking and unlocking switching with the object. In actual use, other locking structures can also be used, as long as they can facilitate quick locking and unlocking operations between the flip frame 32 and the bed frame 1.

[0055] exist Figure 11 , Figure 12The diagram illustrates the structure of a commercially available standard push-button lock 8, which includes a housing 81, a positioning slider 82 housed inside the housing 81, a latch 86 installed through a lock slot 811 on the lower wall of the housing 81, and a button 84 slidably fitted with the positioning slider 82 and the latch 86; as shown Figure 13 As shown, a protrusion 821 is provided inside the positioning slider 82. The slider 83 of the button 84 is slidably mounted on the positioning slider 82. The slider 83 slides relative to the positioning slider 82 and is located above or below the protrusion 821. The latch 86 is provided with an inclined groove 861 for the slider 85 of the button 84 to slide. When the slider 85 slides to the inner end relative to the inclined groove 861, it will cause the latch 86 to retract relative to the housing 81. When the slider 85 slides to the outer end relative to the inclined groove 861, the latch 86 will extend relative to the housing 81. An elastic element 87 is also provided between the inner end of the button 84 and the housing 81.

[0056] In actual operation, when button 84 is pressed, button 84 extends into the housing 81, and the slider 83 is positioned below the protrusion 821 in the positioning slider 82. At this time, the slider 85 of button 84 is located at the inner end of the inclined slide groove 861, the locking tongue 86 is retracted relative to the housing 81, and the button lock 8 is in the unlocked state. When button 84 is pressed again, the slider 83 of button 84 slides out from below the protrusion 821 in the positioning slider 82. At this time, the slider 85 of button 84 is located at the outer end of the inclined slide groove 861, the locking tongue 86 extends relative to the housing 81, and the button lock 8 is in the locked state.

[0057] The bottom surface of the bed frame 1, away from the guardrail 2, is foldable and equipped with support leg 1 4. The bottom end of the guardrail 2 is equipped with support leg 2 5 facing downwards. When the bed is in the unfolded state, it is supported by support leg 1 4 and support leg 2 5. Support leg 1 4 is folded towards the bed frame 1 to help reduce the overall space occupied by the bed in the folded state.

[0058] In this embodiment, the support leg 4 can be installed on the bottom surface of the bed frame 1 via the folding hinge 9, and the support leg 4 can be unfolded or folded relative to the bed frame 1 via the folding hinge 9.

[0059] In this embodiment, the folding hinge 9 can be a conventional commercially available standard product, which can realize and satisfy the switching of the unfolded and folded states of the support leg 4 relative to the bed frame 1.

[0060] Outrigger 1 (4) and Outrigger 2 (5) are either fixed-length structures or adjustable-length structures.

[0061] In this embodiment, the length-adjustable support legs can adopt a conventional sleeve-type bed leg structure. The length can be adjusted by axial extension and retraction between the axially fitted inner and outer cylinders, thereby realizing the height adjustment of the bed in the unfolded state to meet the actual use.

[0062] In practice, the support legs 25 under the guardrail 2 can also be set as foldable structures to further reduce the space occupied by the bed in the folded state.

[0063] In this embodiment, the bed frame 1, guardrail 2, and frame body 3 can be equipped with internal support structures according to actual needs to meet their respective support and protection functions.

[0064] In this embodiment, the bed is installation-free and foldable. A frame 3 can be installed on one side of the guardrail 2 to form a double-sided protective bed. Figure 1 The diagram shows the bed in its unfolded state. The frame 3 located on one side of the guardrail 2 constitutes the headboard or footboard of the bed. Figure 2 The diagram shows the bed frame 1 folded upwards relative to the guardrail 2, with the upper support leg 4 of the bed frame 1 also folded relative to the bed frame 1. Figure 6 The diagram shows the bed frame 1 folded relative to the guardrail 2, with the flip frame 32 in the frame 3 flipped and folded towards the guardrail 2, forming the folded state of the bed, effectively reducing space occupation and facilitating storage and folding.

[0065] In this embodiment, the bed is installation-free and foldable. Alternatively, frame bodies 3 can be installed on both sides of the guardrail 2 to form a three-sided protective bed, such as... Figure 7 The diagram shows the bed in its unfolded state. The frame structures 3 located on both sides of the guardrail 2 constitute the headboard and footboard of the bed, respectively. Figure 8 The diagram shows the bed frame 1 folded upwards relative to the guardrail 2, with the upper support leg 4 of the bed frame 1 also folded relative to the bed frame 1. Figure 9 The diagram shows the bed frame 1 folded relative to the guardrail 2, with the flip frames 32 in both side frames 3 flipped and folded towards the guardrail 2, forming the folded state of the bed, effectively reducing space occupation and facilitating storage and folding.

[0066] exist Figure 9 and Figure 10 The embodiments shown illustrate folding diagrams of the upper legs 4 of the bed frame 1 in different directions. Figure 9 The middle support leg 4 folds vertically. Figure 10 The middle support leg 4 folds laterally, thus achieving the folding of support leg 4 relative to the bed frame 1 in the folded state; the folding direction of support leg 4 relative to the bed frame 1 is determined by the installation of the folding hinge 9, and the folding direction of support leg 4 can be set according to actual needs.

[0067] When folding the bed in actual operation, you can first unlock the lock between the flip frame 32 and the bed frame 1, then apply force to the bed frame 1 to fold towards the guardrail 2, and then apply force to the flip frame 32 to fold towards the guardrail 2 to complete the folding and storage of the bed.

[0068] The bed in this utility model is installation-free and foldable. It can be a metal frame bed or a bed made of wood or other materials. The bed frame 1 and the flip frame 32 can be quickly unfolded and folded relative to the guardrail 2, which is convenient for actual use needs.

[0069] This invention enables quick and convenient folding or unfolding operations, effectively improving the user's actual experience and offering high flexibility in use.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0071] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
