Description

Technical Field

[0001] This utility model relates to the field of living furniture technology, and in particular to a locking mechanism to prevent accidental opening and a storage bed. Background Technology

[0002] In today's furniture market, integrated storage beds have become the preferred choice for many families, especially those in small apartments, due to their combination of sleeping and storage functions. An integrated storage bed typically consists of a bed frame that surrounds the storage space, and a slatted frame that is rotatably connected to the bed frame at one end to cover the upper opening of the storage space. A locking mechanism is usually installed between the other end of the slatted frame and the bed frame; opening the locking mechanism allows the slatted frame to be rotated open, enabling the retrieval of items from the storage space.

[0003] To ensure safety and structural stability, a locking mechanism is typically installed between the other end of the slatted frame and the bed frame. When closed, this locking mechanism securely locks the slatted frame to the bed frame, preventing accidental opening of the storage space due to force or vibration. When the user needs to access items, the locking mechanism can be released by specific operations (such as pulling a handle, pressing a button, or rotating a knob), allowing the slatted frame to be flipped open.

[0004] However, the locking mechanisms used in most mainstream integrated storage beds are single-lock designs. This means that unlocking is instantaneous with a single action (e.g., rotating the handle or pressing a button). While this design is convenient, it also presents significant safety hazards:

[0005] (1) High risk of accidental operation by children: Since the unlocking method is straightforward and does not require complicated steps, curious children are very likely to imitate the operation when adults are not paying attention and accidentally open the heavy slatted frame. This may not only damage the items in the storage space, but more seriously, the falling slatted frame may easily pinch children's fingers or heads, causing personal injury.

[0006] (2) Possibility of accidental opening: During daily activities such as making the bed, jumping or moving heavy objects, the single-point lock may be accidentally loosened due to continuous force or vibration, causing the storage cover to suddenly pop open and threatening the user's safety.

[0007] Existing single-locking mechanisms have significant shortcomings in home security, especially failing to meet the higher safety requirements of families with children. Therefore, this invention aims to develop an anti-accidental-opening locking mechanism that effectively solves the problem of existing locking mechanisms being easily opened by accident, resulting in poor security.

[0008] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] One objective of this invention is to provide a locking mechanism and storage bed that prevents accidental opening, effectively solving the problem that existing locking mechanisms are prone to accidental opening, resulting in poor security.

[0010] To achieve the above objectives, this utility model provides an anti-accidental opening locking mechanism, comprising:

[0011] Locking mechanism housing for mounting on the bed frame;

[0012] A rotating hook plate is rotatably mounted on the housing of the locking mechanism for engaging the frame;

[0013] A tension spring is connected between the rotating hook plate and the locking mechanism housing;

[0014] An elastic telescopic component is located on the side of the rotating hook plate away from the tension spring;

[0015] The rotating hook plate has three working positions:

[0016] Locking position: The rotating hook plate rotates clockwise under the action of the tension spring to lock the frame and disengage from the elastic telescopic component;

[0017] Preparing to unlock position: The rotating hook plate is initially reversed by the drive to contact the elastic telescopic component, the rotating hook plate remains locked to the frame, and the elastic telescopic component is in the extended state;

[0018] Unlock position: The rotating hook plate is driven to continue to reverse and squeeze the elastic telescopic component, the rotating hook plate disengages from the frame, and the elastic telescopic component is in a retracted state.

[0019] Optionally, the upper end of the rotating hook plate protrudes above the housing of the locking mechanism and is provided with a slot with an opening facing away from the tension spring;

[0020] The middle part of the rotating hook plate is rotatably connected to the housing of the locking mechanism via a rotating shaft;

[0021] The lower end of the rotating hook plate protrudes below the housing of the locking mechanism to form an operating section.

[0022] Optionally, the elastic telescopic component and the operating part are arranged at a distance from each other;

[0023] The rotating hook plate also includes a follower rod, one end of which is connected to the operating part, and the other end moves away from or closer to the elastic telescopic component as the operating part rotates.

[0024] Optionally, the elastic telescopic component includes:

[0025] A sleeve housing, which is fixedly disposed relative to the locking mechanism housing;

[0026] A telescopic slide rod, one end of which is slidably inserted into the sleeve housing, and the other end protruding to the outside of the sleeve housing and being positioned opposite to the follower rod;

[0027] A sliding rod compression spring is located inside the sleeve housing and is used to drive the telescopic sliding rod to slide outward relative to the sleeve housing.

[0028] Optionally, the telescopic slide rod is provided with a first magnetic attractor at one end near the follower rod, and the follower rod is provided with a second magnetic attractor that is magnetically connected to the first magnetic attractor at one end near the telescopic slide rod;

[0029] When the rotating hook plate is in the pre-unlock position, the first magnetic component and the second magnetic component are magnetically connected to maintain the pre-unlock position.

[0030] Optionally, the locking mechanism housing is provided with a transverse guide groove located between the elastic telescopic component and the operating part, and the follower rod is slidably installed in the transverse guide groove.

[0031] Optionally, the follower rod is connected to the operating part via a flexible connector.

[0032] Optionally, the flexible connector is a steel wire rope or a thin steel cable.

[0033] Optionally, the operating part may be detachably fitted with an extension sleeve.

[0034] On the other hand, a storage bed is provided, comprising:

[0035] A bed frame, on which the aforementioned anti-accidental opening locking mechanism is installed;

[0036] The slatted frame has one end rotatably connected to the bed frame and the other end provided with a limiting post for engaging with the anti-accidental opening locking mechanism.

[0037] The beneficial effects of this utility model are as follows: It provides a locking mechanism to prevent accidental opening and a storage bed, the working process of which is as follows:

[0038] Initially, the rotating hook plate rotates clockwise under the action of the tension spring to lock the slatted frame and remains in the locked position, thereby restricting the relative rotation between the slatted frame and the bed frame; at this time, the rotating hook plate disengages from the elastic telescopic assembly.

[0039] If the rotating hook is turned so that it reverses, the rotating hook will first reverse to the pre-unlock position that contacts the elastic telescopic component. At this time, although the rotating hook has rotated a certain angle in the unlocking direction, it has not completely disengaged from the unlocked state. Therefore, the rotating hook is still locked onto the frame, and the frame cannot be opened. It should be noted that since the elastic telescopic component is in the extended state at this time, continuing to rotate the rotating hook requires applying greater force to overcome the elastic force of the elastic telescopic component. Therefore, if the anti-accidental opening locking mechanism is not intentionally opened, but is accidentally opened, it will often remain in the current state, that is, although the rotating hook has been reversed by a small angle, the frame is still locked and cannot be opened.

[0040] If it is necessary to open the slat frame, a greater force needs to be applied from the pre-unlocked position to drive the rotating hook plate to continue to reverse, so that the rotating hook plate squeezes the elastic telescopic component until the rotating hook plate is completely disengaged from the slat frame, then the rotation restriction on the slat frame can be released, and the slat frame can be opened.

[0041] Therefore, the anti-accidental opening locking mechanism and storage bed provided by this utility model can effectively solve the problem that existing locking mechanisms are easily accidentally opened, resulting in poor security. Attached Figure Description

[0063] See Figure 1 and Figure 2 The storage bed provided in this embodiment includes a bed frame 100, a slatted frame 200, and an anti-accidental opening locking mechanism 300 installed on the bed frame 100.

[0064] One end of the slatted frame 200 is rotatably connected to the bed frame 100, and the other end is provided with a limiting post 200a for engaging with the anti-accidental opening locking mechanism 300.

[0065] See Figure 3 and Figure 4 The anti-accidental opening locking mechanism 300 includes:

[0066] Locking mechanism housing 1, for mounting on bed frame 100;

[0067] The rotating hook plate 2 is rotatably mounted on the locking mechanism housing 1 and is used to engage the limiting post 200a on the frame 200.

[0068] A tension spring 3 is connected between the rotating hook plate 2 and the locking mechanism housing 1;

[0069] The elastic telescopic component 4 is located on the side of the rotating hook plate 2 away from the tension spring 3;

[0070] The rotating hook plate 2 has three working positions:

[0071] Locking position: The rotating hook plate 2 rotates clockwise under the action of the tension spring 3 to lock the frame 200 and disengage from the elastic telescopic component 4;

[0072] Preparing to unlock position: The rotating hook plate 2 is driven to rotate in reverse for the first time to contact the elastic telescopic component 4, the rotating hook plate 2 remains locked to the frame 200, and the elastic telescopic component 4 is in the extended state;

[0073] Unlock position: The rotating hook plate 2 is driven to continue to reverse and squeeze the elastic telescopic component 4, the rotating hook plate 2 disengages from the frame 200, and the elastic telescopic component 4 is in a retracted state.

[0074] The anti-accidental opening locking mechanism 300 and storage bed provided by this utility model work as follows:

[0075] Initially, the rotating hook plate 2 rotates clockwise under the action of the tension spring 3 until it clamps the frame 200 and remains in the locked position, thereby restricting the relative rotation between the frame 200 and the bed frame 100; at this time, the rotating hook plate 2 disengages from the elastic telescopic component 4.

[0076] If the rotating hook plate 2 is turned so that it reverses, it will first reverse to the pre-unlock position where it contacts the elastic telescopic component 4. At this time, although the rotating hook plate 2 has rotated a certain angle in the unlocking direction, it has not completely disengaged from the unlocking state. Therefore, the rotating hook plate 2 is still locked to the frame 200, and the frame 200 cannot be opened. It should be noted that since the elastic telescopic component 4 is in the extended state at this time, continuing to rotate the rotating hook plate 2 requires applying greater force to overcome the elastic force of the elastic telescopic component 4. Therefore, if the anti-accidental opening locking mechanism 300 is not intentionally opened, but is accidentally opened, it will often remain in the current state, that is, although the rotating hook plate 2 has been reversed by a small angle, the frame 200 is still locked and cannot be opened.

[0077] If it is necessary to open the slat frame 200, a greater force needs to be applied on the basis of the pre-unlocked position to drive the rotating hook plate 2 to continue to reverse, so that the rotating hook plate 2 squeezes the elastic telescopic component 4 until the rotating hook plate 2 is completely separated from the slat frame 200, then the rotation restriction on the slat frame 200 can be released, and the slat frame 200 can be opened.

[0078] Therefore, the anti-accidental opening locking mechanism 300 and storage bed provided by this utility model can effectively solve the problem that existing locking mechanisms are easily accidentally opened, resulting in poor security.

[0079] In this embodiment, the upper end of the rotating hook plate 2 protrudes above the locking mechanism housing 1 and is provided with a slot 201 with an opening facing away from the tension spring 3;

[0080] The middle part of the rotating hook plate 2 is rotatably connected to the locking mechanism housing 1 via a rotating shaft 203;

[0081] The lower end of the rotating hook plate 2 protrudes below the locking mechanism housing 1 to form an operating part 202.

[0082] It is understood that the rotating hook plate 2 is mounted on the locking mechanism housing 1 via the central rotating shaft 203, thereby achieving a lever effect. The upper slot 201 is used to hook the limiting post 200a of the frame 200. The lower operating part 202 extends out of the housing, facilitating the user (usually with their foot) to apply operating force.

[0083] In this embodiment, the elastic telescopic component 4 includes:

[0084] Elastic telescopic component 4, which is disposed opposite to the operation part 202 at a distance;

[0085] Follower rod 204, one end of which is connected to the operating part 202, and the other end moves away from or towards the elastic telescopic component 4 as the operating part 202 rotates.

[0086] Furthermore, the elastic telescopic component 4 includes:

[0087] Sleeve housing 401, which is fixedly disposed relative to the locking mechanism housing 1;

[0088] Telescopic slide rod 402, one end of which is slidably inserted into the sleeve housing 401, and the other end protrudes to the outside of the sleeve housing 401 and is arranged opposite to the follower rod 204;

[0089] A sliding rod compression spring 403 is located inside the sleeve housing 401 and is used to drive the telescopic sliding rod 402 to slide outward relative to the sleeve housing 401.

[0090] Optionally, the telescopic slide rod 402 is provided with a first magnetic attractor 404 at one end near the follower rod 204, and the follower rod 204 is provided with a second magnetic attractor 205 at one end near the telescopic slide rod 402, which is magnetically connected to the first magnetic attractor 404.

[0091] When the rotating hook plate 2 is in the pre-unlock position, the first magnetic member 404 and the second magnetic member 205 are magnetically connected to maintain the pre-unlock position.

[0092] Optionally, one of the two magnetic components may be a magnet, and the other may be an iron block or also a magnet.

[0093] In this embodiment, the locking mechanism housing 1 is provided with a transverse guide groove 101 located between the elastic telescopic component 4 and the operating part 202, and the follower rod 204 is slidably installed in the transverse guide groove 101. The follower rod 204 is connected to the operating part 202 through a flexible connector 206. For example, the flexible connector 206 is a steel wire rope or a thin steel cable.

[0094] The detailed working process of the anti-accidental opening locking mechanism 300 provided in this embodiment is as follows:

[0095] (1) Locking position: Under the tension of the tension spring 3, the rotating hook plate 2 rotates clockwise around the central rotating shaft 203, causing the upper end of the slot 201 to lock the limiting post 200a of the frame 200. At this time, the operating part 202 at the lower end of the rotating hook plate 2 pulls the follower rod 204 through the flexible connector 206, causing one end of the follower rod 204 to move away from the elastic telescopic component 4. The slide spring 403 in the elastic telescopic component 4 drives the telescopic slide rod 402 to be in the extended state, but it separates from the second magnetic suction member 205 at the end of the follower rod 204. Therefore, the rotating hook plate 2 disengages from the elastic telescopic component 4, and the mechanism is stably locked.

[0096] (2) Preparatory unlocking position: When the operating part 202 at the lower end of the rotating hook plate 2 is kicked or manually moved, causing the rotating hook plate 2 to reverse over the tension of the tension spring 3 for the first time, the rotational movement of the operating part 202 pushes the follower rod 204 close to one end face of the elastic telescopic component 4, causing the follower rod 204 to slide in the transverse guide groove. The other end of the follower rod 204 drives the second magnetic suction member 205 on it to contact and attract the first magnetic suction member 404 at the end of the telescopic slide rod 402. At this time, the telescopic slide rod 402 is in the extended state under the action of the slide rod compression spring 403. The magnetic attraction of the two magnetic suction members, the tension of the tension spring 3, and the elastic force of the slide rod compression spring 403 are balanced, so that the rotating hook plate 2 is held in this position. The slot 201 of the rotating hook plate 2 still clamps the limiting post 200a of the frame 200, but due to the magnetic attraction between the two magnetic parts, a certain force and / or sound feedback will be provided, and the user can obtain obvious operation feedback and know that the unlocking action has been initiated.

[0097] (3) Unlocking Position: When a greater driving force is applied to the operating part 202, causing the rotating hook plate 2 to continue to reverse, the operating part 202 further pushes the follower rod 204, causing the follower rod 204 to press the telescopic slide rod 402. This operating force needs to overcome the elastic force of the slide rod compression spring 403, forcing the telescopic slide rod 402 to retract into the sleeve housing 401, that is, the elastic telescopic component 4 is in the retracted state. At the same time, the rotating hook plate 2 continues to reverse, eventually causing its upper end slot 201 to completely disengage from the limiting post 200a of the frame 200, thus achieving unlocking.

[0098] (4) Reset: When the operating force on the operating part 202 is released, the tension of the tension spring 3 will pull the rotating hook plate 2 to rotate clockwise and reset. The flexible connector 206 will pull the follower rod 204 to slide away from the elastic telescopic component 4, so that the second magnetic suction member 205 disengages from the first magnetic suction member 404. The slide bar compression spring 403 will then push the telescopic slide bar 402 to extend again, and the anti-accidental opening locking mechanism 300 will return to the locked position.

[0099] See Figure 5 Optionally, the telescopic slide rod 402 has a radially protruding limiting boss 4021 at one end extending into the sleeve housing 401. The size of the limiting boss 4021 is larger than the size of the opening in the sleeve housing 401 through which the telescopic slide rod 402 passes, thereby restricting the telescopic slide rod 402 from completely detaching from the sleeve housing 401; and / or, the two ends of the slide rod compression spring 403 are respectively fixed to the sleeve housing 401 and the telescopic slide rod 402 to restrict the telescopic slide rod 402 from completely detaching from the sleeve housing 401.

[0100] It should be noted that during the above-mentioned operation, with the locking mechanism housing 1 as the reference, the follower rod 204 only slides horizontally left and right, while the operating part 202 needs to rotate relative to the locking mechanism housing 1. If the follower rod 204 and the operating part 202 are rigidly connected, the two movements of rotation and translation will interfere with each other, causing the rotating hook plate 2 and the follower rod 204 to jam. The design of the flexible connector 206 can perfectly solve the problem of motion interference between the two.

[0101] Specifically, when the tension spring 3 drives the rotating hook plate 2 to rotate forward, the flexible connector 206 is tightened, and the follower rod 204 is driven to slide away from the elastic telescopic component 4 through the tension, thereby causing the elastic telescopic component 4 to separate from the follower rod 204.

[0102] When the foot-operated unit 202 causes the rotating hook plate 2 to reverse, the flexible connector 206 does not function, and the operating unit 202 abuts against the end face of the follower rod 204 away from the elastic telescopic component 4, thereby directly pushing the follower rod 204 towards the elastic telescopic component 4.

[0103] In this embodiment, an extension sleeve 5 is detachably fitted onto the operating part 202. The extension sleeve 5 is fitted onto the operating part 202, extending the lever arm and providing an operating point that is easier to detect, thus saving effort and improving the convenience of operation.

[0104] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
