Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a bed. Background Technology

[0002] Existing bed frame structures, especially in scenarios where portability and stability are required (such as temporary guest beds, children's beds, and pet beds), often struggle to balance support performance and convenience.

[0003] One common type of frame lacks a dedicated reinforcing support structure and relies solely on the basic frame to support the bed. When subjected to large loads or long-term use, this type of frame is prone to deformation or even damage due to uneven stress, resulting in unsatisfactory support and durability.

[0004] To improve stability, some designs use fixed connecting legs. However, these rigidly connected supports cannot be effectively stored when the bed is not in use, resulting in a bulky overall structure that greatly increases the difficulty and cost of packaging and storage, and is also extremely inconvenient for users.

[0005] Other designs introduce a rotation function for the support components to achieve folding, but their rotation methods are usually relatively simple and lack an effective limiting mechanism in the unfolded state. The support components are prone to accidental rotation or displacement under external force, posing stability and safety hazards.

[0006] Adding complex independent locking mechanisms to such simple rotating support components would inevitably lead to increased structural complexity, more parts, more complicated assembly processes, and higher production costs, which would hinder market promotion and popularization.

[0007] Therefore, there is an urgent need in this field for a bed frame solution that can provide reliable support while achieving smooth, stable folding and closing, and with a simple and efficient structure. Utility Model Content

[0008] The main purpose of this invention is to propose a bed that achieves both stable support and compact folding by having the newly added support pillars of the bed frame perform a compound movement during folding and unfolding.

[0009] To achieve the above objectives, this utility model proposes a bed, including a frame body and at least one support column for reinforcement.

[0010] The support column is movably connected to the frame body and can be switched between a retracted state and a usable state.

[0011] When the support column switches between the retracted state and the used state, the movement trajectory of the support column includes both axial movement and rotation.

[0012] Furthermore, when the support column moves to the use state or the retracted state, the axial movement cooperates with the frame body to constrain the rotational freedom of the support column.

[0013] Preferably, the frame body has a connecting groove, the connecting groove including a groove wall area and at least one clearance space;

[0014] The upper end of the support column is provided with a guide hole extending vertically, and a connector is movably inserted through the guide hole and rotatably connected to the frame body;

[0015] The support column is rotatable about the connector and is axially movable relative to the connector along the extension direction of the guide hole.

[0016] When the support column moves axially to the point where its upper end is opposite to the groove wall area of ​​the connecting groove, the rotation of the support column is restricted by the groove wall area.

[0017] When the support column moves axially to the point where its upper end is opposite the clearance position, the support column gains rotation space provided by the clearance position, thereby enabling it to rotate and switch between the folded state and the use state.

[0018] Preferably, the connecting groove and the clearance space are directly formed in the frame body;

[0019] Alternatively, a connecting seat is fixedly provided on the frame body, and the connecting groove and clearance space are formed on the connecting seat;

[0020] The support column is rotatably connected to the frame body or the connecting seat via the connector.

[0021] Preferably, it also includes software disposed on the frame body.

[0022] Preferably, the number of the supports is even and they are symmetrically arranged on the frame body.

[0023] Preferably, the frame body is a foldable structure.

[0024] Preferably, the frame body includes a foldable frame and a plurality of support leg assemblies disposed on the frame;

[0025] The frame is formed by connecting multiple connecting rods through connectors, and two adjacent connecting rods are rotatably connected to different connecting parts of the same connector;

[0026] The connecting rod is provided with a folding joint in the middle, and the folding joint has a locked state and an unlocked state;

[0027] When the folding joint is in the locked state, the connecting rod to which it is located is kept in a supported state;

[0028] When the folding joint is in the unlocked state, the two ends of the connecting rod can move apart or closer together.

[0029] The support leg assembly is linked to the frame, so that the support leg assembly can switch to the supporting state as the frame unfolds, and switch to the folded state as the frame closes.

[0030] Preferably, the support assembly includes a first support leg, a second support leg, and a base;

[0031] The lower end of the first leg is rotatably connected to the first part of the foot base, and the lower end of the second leg is rotatably connected to the second part of the foot base;

[0032] The upper end of the first leg is rotatably connected to one of the two adjacent connecting rods in the frame, and its rotation plane is limited by the extension direction of the connecting rod; the upper end of the second leg is rotatably connected to the other of the two adjacent connecting rods, and its rotation plane is limited by the extension direction of the other connecting rod.

[0033] Preferably, the connecting rod is composed of a first sub-rod and a second sub-rod, and the folding joint is disposed between the first sub-rod and the second sub-rod as an intermediate connecting member;

[0034] The folding joint includes a housing, an unlocking component, and a pair of linkage lever mechanisms disposed within the housing;

[0035] The linkage lever mechanism has a first state in which it interacts with the inner ends of the first and second sub-bars, and a second state in which the interaction is released.

[0036] The linkage lever mechanism is biased in the first state by an elastic reset member;

[0037] Operating the unlocking component can overcome the elastic tendency of the elastic reset component and drive the linkage lever mechanism to switch to the second state.

[0038] Preferably, the linkage lever mechanism includes two drive units capable of moving synchronously in opposite directions or in opposite directions, and two locking units controlled by the two drive units in a linkage manner and whose movement direction is opposite to that of the two drive units;

[0039] The two locking parts are respectively used to interact with the first sub-rod and the second sub-rod;

[0040] The elastic reset element acts between the two driving parts and provides an elastic tendency for the two driving parts to move closer to each other;

[0041] The unlocking component is movably disposed on the outer shell, and the unlocking component can drive the two driving parts to overcome the elastic tendency of the elastic reset component and move apart through linear motion;

[0042] When the linkage lever mechanism is in the first state, the two driving parts remain close to each other, and the two locking parts remain far apart, so as to lock the first sub-rod and the second sub-rod.

[0043] When the unlocking component is operated to make a linear movement, the unlocking component drives the two driving parts to overcome the elastic tendency and make a separation movement, which in turn drives the two locking parts to make a proximity movement, so that the linkage lever mechanism switches to the second state to release the locking of the first sub-rod and the second sub-rod.

[0044] Preferably, the strut is supported and connected to the folding joint.

[0045] This invention cleverly combines stable support with convenient storage by enabling the support column to perform a composite motion involving both axial movement and rotation when switching between its retracted and usable states. Axial movement is used to lock and unlock the column, ensuring stable support. In its extended state, the structure provides reliable positioning, ensuring structural stability; in its retracted state, it compactly stores the support column, avoiding space redundancy caused by additional support components. When this support column structure is applied to a foldable frame, its advantages are further amplified, achieving perfect coordination between the partial retraction and extension of the support column and the overall folding of the frame. Ultimately, this results in a stable and reliable product during use, and maximizes space saving when not in use. Attached Figure Description

[0054] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0055] It should be noted that if any directional indication is involved in the embodiments of this utility model (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.), then the directional indication is only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly.

[0056] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0057] This utility model proposes a bed, specifically a pet bed.

[0058] In this embodiment of the utility model, such as Figures 1 to 8 As shown, the bed includes a frame body and a soft body 4, such as a mattress or cloth cover, placed on it for the pet to lie on.

[0059] Specifically, the frame body constitutes the basic framework of the bed. To enhance the overall structural stability and load-bearing capacity, at least one support column 1 for reinforcement is movably connected to the frame body. This support column 1 can switch between a folded state and a usable state. The switching process is not a simple rotation around an axis, but follows a complex motion trajectory, that is, the movement of the support column 1 simultaneously includes axial movement along its own length and rotation around its connection point.

[0060] This composite motion mechanism brings key benefits: when the support column 1 finally reaches the working or stowed state through the aforementioned composite motion, its final axial movement will ensure a tight fit with the frame body, thereby constraining the rotational freedom of the support column 1. In the working state, this constraint ensures that the support column 1 will not rotate accidentally, providing stable support; in the stowed state, this constraint allows the support column 1 to be safely and compactly stored without detaching due to shaking.

[0061] In a preferred embodiment, the above-mentioned combined motion and limiting functions are achieved through a sophisticated structure:

[0062] Specifically, a connecting groove 100 is provided on the frame body. The connecting groove 100 includes a main groove wall area 101 and at least one clearance space 102. The upper end of the support column 1 is provided with a vertically extending guide hole 11. A connector 2, such as a bolt or pin, is movably inserted into this guide hole 11, and the support column 1 is rotatably connected to the frame body. This structure allows the support column 1 to rotate about the connector 2 as an axis, and also to move axially up and down relative to the connector 2 along the extension direction of the guide hole 11.

[0063] When it is necessary to switch the state of the support column 1, first move the support column 1 axially so that its upper end is positioned opposite the clearance position 102 of the connecting groove 100. At this time, the clearance position 102 provides the necessary space for the rotation of the support column 1, allowing it to rotate smoothly. After rotating to the target position, such as the used state or the retracted state, move the support column 1 axially again so that its upper end leaves the clearance position 102 and is once again aligned with the groove wall area 101 of the connecting groove 100. At this time, the groove wall area 101 will impede the rotation of the support column 1, thereby forming an effective limit and locking the support column 1 in the current state.

[0064] Specifically, the aforementioned connecting groove 100 and clearance space 102 can be directly formed on the pipe wall or plate of the frame body. In another embodiment, to facilitate processing and ensure strength, a connecting seat 3 can be separately fixed on the frame body, and the connecting groove 100 and clearance space 102 can be formed on this connecting seat 3. The support column 1 is rotatably connected to this connecting seat 3 through the connector 2.

[0065] Specifically, in this embodiment, as shown in the attached figure, the frame body is quadrilateral. In order to achieve the best balance support effect, the number of support columns 1 is preferably set to an even number, such as two or four, and they are symmetrically arranged on both sides or four sides of the frame body. The specific design can be based on the number of sides of the frame body. For example, when the frame body is hexagonal, two, four or six support columns 1 can be arranged.

[0066] It should be noted that when the frame body is in the shape of a triangle or pentagon with an odd number of sides, the number of support columns 1 is preferably odd.

[0067] Furthermore, the frame body of this utility model can be designed as a foldable structure, greatly improving the product's portability and storage convenience. The foldable frame body mainly includes a foldable frame and multiple support leg components 5 disposed below the frame. It should be noted that the phrase "the frame body is quadrilateral" mentioned in the above embodiments specifically corresponds to "the frame is quadrilateral," and other shapes of the frame body mentioned in the above embodiments should also be specifically understood as other shapes of the frame.

[0068] Specifically, the frame is formed by connecting multiple connecting rods 6 together via connectors 7. Adjacent connecting rods 6 are rotatably connected to different connecting parts of the same connector 7. More importantly, each connecting rod 6 has a folding joint 8 in its middle. This folding joint 8 has a locked state and an unlocked state. When the folding joint 8 is locked, the entire connecting rod 6 is kept in a straight, supported state; when the folding joint 8 is switched to the unlocked state, the two ends of the connecting rod 6 can move apart or closer together, thereby realizing the folding and unfolding of the frame.

[0069] Specifically, the support leg assembly 5 and the frame are linked together. When the frame is unfolded, it will drive the support leg assembly 5 to move synchronously to the unfolded support state; when the frame is closed, the support leg assembly 5 will also fold up, forming a compact whole with the frame.

[0070] Furthermore, in a specific embodiment of the support leg assembly 5, each support leg assembly 5 includes a first leg 51, a second leg 52, and a common base 53. The lower end of the first leg 51 is rotatably connected to a first part of the base 53, and the lower end of the second leg 52 is rotatably connected to a second part of the base 53. The upper end of the first leg 51 is rotatably connected to one of two adjacent connecting rods 6 in the frame, and its plane of rotation is limited by the extension direction of the connecting rod 6. Similarly, the upper end of the second leg 52 is rotatably connected to the other of the two adjacent connecting rods 6, and its plane of rotation is also limited by the extension direction of the other connecting rod 6. This linkage design ensures the coordination and stability of the frame's movements during unfolding and folding.

[0071] Specifically, the folding joint 8 in the middle of the connecting rod 6 can have the following structure:

[0072] The connecting rod 6 consists of a first sub-rod 61 and a second sub-rod 62, and the folding joint 8 is disposed as an intermediate connecting member between the first sub-rod 61 and the second sub-rod 62. The folding joint 8 includes a housing 81, an unlocking member 82, and a pair of linkage lever mechanisms 200 disposed inside the housing 81.

[0073] Specifically, the linkage lever mechanism 200 has two states. In the first state, it interacts with the inner ends of the first sub-rod 61 and the second sub-rod 62, locking them together and keeping the entire connecting rod 6 rigid. In the second state, this interaction is released, allowing the first sub-rod 61 and the second sub-rod 62 to move relative to each other. A resilient reset element 83, such as a spring, provides a biasing force to the linkage lever mechanism 200, keeping it in the first state, i.e., the locked state, under normal conditions.

[0074] When the bed needs to be folded, the operator applies the unlocking element 82, causing it to move, for example by pressing it linearly. This overcomes the elastic force of the elastic reset element 83, driving the linkage lever mechanism 200 to switch from the first state to the second state, thereby releasing the lock on the first sub-rod 61 and the second sub-rod 62, allowing the frame to be folded. After releasing the unlocking element 82, the linkage lever mechanism 200 automatically returns to the first state under the action of the elastic reset element 83, preparing for the next unfolding and locking.

[0075] Furthermore, specifically regarding the internal mechanism of the linkage lever mechanism 200, it includes two drive units 84 capable of synchronously moving towards or away from each other, and two locking units 85 controlled by the linkage of these two drive units 84. The movement direction of the two locking units 85 is opposite to the movement direction of the two drive units 84. An elastic reset member 83 acts between the two drive units 84, providing them with an elastic tendency to move closer together. An unlocking member 82 is movably disposed on the housing 81. When the unlocking member 82 moves linearly, it can drive the two drive units 84 to overcome the elastic tendency of the elastic reset member 83 and move away from each other, thereby causing the two locking units 85 to move synchronously closer together, thus achieving the effect of switching the linkage lever mechanism 200 from the first state to the second state.

[0076] Specifically, the contact points between the unlocking member 82 and the two driving parts 84 respectively form two fulcrums. Through these two fulcrums, the linear motion of the unlocking member 82 can smoothly transmit force to the driving parts 84, and using the lever principle, efficiently push the two driving parts 84 to move apart. Conversely, when the elastic reset member 83 drives the two driving parts 84 to automatically reset, it can also smoothly transmit force to the unlocking member 82 through these two fulcrums, causing the unlocking member 82 to automatically reset.

[0077] Furthermore, the unlocking component 82 is also provided with an integrally formed or fixedly connected top plate 86. During the unlocking process, the linear movement of the unlocking component 82 synchronously drives the top plate 86 to move, bringing it closer to and ultimately pushing against the middle of the elastic reset component 83, i.e., the spring. After the middle of the spring is pushed up, the linear distance between its two ends is forced to shorten. The force generated by this deformation will, in turn, act on the two driving parts 84, causing them to tend to move closer to each other. This design ensures that during the unlocking process, the two driving parts 84 can always maintain a tight fit with the fulcrum on the unlocking component 82, eliminating gaps between moving parts, making the entire mechanism move more accurately and reliably, avoiding loosening and abnormal noise, and providing a more stable automatic reset effect for the unlocking component 82.

[0078] When the linkage lever mechanism 200 is in the first state, i.e., the locked state, the two drive parts 84 remain close together under the action of the spring, thereby forcing the two locking parts 85 to remain separate and tightly locking the inner ends of the first sub-rod 61 and the second sub-rod 62, thus achieving locking. When the unlocking part 82 is operated to make a linear movement, it pushes the two drive parts 84 to move apart through the fulcrum, thereby driving the two locking parts 85 to move closer together, disengaging from the locking of the first sub-rod 61 and the second sub-rod 62, causing the linkage lever mechanism 200 to switch to the second state, i.e., the unlocked state, and the connecting rod 6 can then be folded.

[0079] In addition, a conventional guide structure is provided between the unlocking member 82 and the outer shell 81 to constrain the unlocking member 82 to move in a straight line. A conventional limiting structure is provided between the locking part 85 and the outer shell 81 to limit the range of motion of the locking part 85. The guide structure and the limiting structure can refer to the prior art, and their specific structural principles will not be described in detail here.

[0080] Specifically, based on the foregoing embodiments, the support column 1 of this utility model may also have another configuration:

[0081] The support column 1 can be directly supported and connected to the folding joint 8. Since the folding joint 8 itself is a key load-bearing component in the connecting rod 6, possessing sufficient structural strength and stability, the upper end of the support column 1 is connected to the outer shell 81 of the folding joint 8 using the aforementioned connection method. Alternatively, a connecting seat 3 can be separately fixed to the outer shell 81 of the folding joint 8, and then the connecting groove 100 and clearance 102 can be formed on this connecting seat 3. The support column 1 is then rotatably connected to this connecting seat 3 via the connecting piece 2. The structural integration of the support column 1 and the folding joint 8 is a particularly preferred implementation. This arrangement allows the reinforcing support force of the support column 1 to act directly on one of the most stress-concentrated and sensitive parts of the frame, more effectively enhancing the rigidity and stability of the overall structure.

[0082] Specifically, the lower end of the support column 1 is provided with an anti-slip component 9 to increase contact friction.

[0083] Understandable, such as Figure 8 As shown, after the support column 1 is rotated to the use state with its lower end facing down and the rotational freedom of the support column 1 is constrained by axial movement, the lower end wall of the support column 1 and the bottom wall of the foot 53 should be at the same horizontal plane or close to the same horizontal plane.

[0084] This invention cleverly combines stable support with convenient storage by enabling the support column to perform a composite movement involving both axial movement and rotation when switching between its retracted and usable states, and by using axial movement to lock and unlock the state. The structure itself provides reliable limiting in the extended state, ensuring stable support; in the retracted state, it compactly stores the support column, avoiding space redundancy caused by additional support components. When this support column structure is applied to a foldable frame body, its advantages are further enhanced, achieving perfect coordination between the partial retraction and extension of the support column and the overall folding of the frame. Ultimately, this makes the entire product stable and reliable in use, and achieves maximum space saving when not in use.

[0085] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
