CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the priority benefit of Chinese Patent Application Serial Number 2025105607536, filed on Apr. 29th, 2025, the full disclosure of which is incorporated herein by reference.

TECHNICAL FIELD OF THE INVENTION

This application relates to a furniture, and in particular, to a wall bed having a self-locking function.

DESCRIPTION OF THE PRIOR ART

In a modern living environment, storage and comfort are emphasized. In some densely populated cities and countries, storage and organization are not limited to daily utensils. Moreover, some living environments are not very spacious nowadays, making a living area very compact. As a result, people may generally arrange their living environments better within a limited space. Besides, a bed is one of essential household items in people's home life. However, generally, the bed occupies a relatively large area and often take up a considerable living space. Therefore, a larger space for activities obtained by improving a use manner of the bed also arises accordingly. Therefore, a foldable wall bed industry arises accordingly.

Refer to FIG. 1 which is a schematic structural diagram of a current wall bed. As shown in the figure, a structure of a current wall bed S generally includes a wall bed cabinet and a wall bed body. One side of the wall bed body is connected to a link assembly S11 arranged in the wall bed cabinet, to achieve a rotational connection to the wall bed cabinet, and the other side of the wall bed body may rotate around a rotational connection side between the wall bed body and the wall bed cabinet, to implement unfolding and folding actions of the wall bed body. During implementation of this application, the applicant finds that there is no self-locking structure between the wall bed cabinet and the wall bed body of the current wall bed S. When the wall bed cabinet is not securely mounted or loosened, there may be a risk that the wall bed cabinet tips over towards the wall bed body (for example, an inclination direction shown in FIG. 1), leading to an extremely great potential security risk of the wall bed S. At the same time, most wall beds currently on the market are transported as a whole or in folded packages, resulting in large packaging dimensions, which typically requires two people to carry, thereby significantly increasing transportation costs, indirectly raising overall costs, and placing a heavier burden on customers.

Referring to FIGS. 2-4, FIG. 2 is a three-dimensional view of an unfolded state of a wall bed having a self-locking function according to a first implementation of this application, FIG. 3 is a three-dimensional view of a folded state, and FIG. 4 is a three-dimensional view of a driving assembly and a locking member. As shown in the figures, a wall bed 1 having a self-locking function in this implementation includes a wall bed cabinet 2, a gas spring 3, a wall bed body 4, a self-locking stopper 5, a driving assembly 6, and a locking member 7. One end of the gas spring 3 is pivotally connected to an upper part of the wall bed cabinet 2. One end of the wall bed body 4 is pivotally connected to the other end of the gas spring 3. When the wall bed body 4 is stored, a pivotal end between the wall bed body 4 and the gas spring 3 moves towards the bottom of the wall bed cabinet 2, and the other end of the wall bed body 4 is flipped upwards around the pivotal end between the wall bed body and the gas spring 3 and stored in the wall bed cabinet 2. The gas spring 3 is a part that can implement functions such as supporting, buffering, braking, and height and angle adjustment. Since the gas spring 3 is a common structure in the art, details are not described herein again in this implementation.

Referring to FIGS. 5-7 together, FIG. 5 is a partial three-dimensional view of a self-locking state of the wall bed having a self-locking function according to the first implementation of this application, FIG. 6 is a front view of FIGS. 5 and 7 is a cross-sectional view of a self-locking state in which the driving assembly is disposed in a frame side tube. As shown in the figures, the self-locking stopper 5 is fixedly arranged on the wall bed cabinet 2. The self-locking stopper 5 corresponds to the wall bed body 4. "Correspond" herein means that the self-locking stopper 5 is located on one side of the wall bed body 4. As shown in FIG. 5, the self-locking stopper 5 is located on a left side of the wall bed body 4. The self-locking stopper 5 has a stopping surface 51. In this implementation, the self-locking stopper 5 is a rectangular block, and the stopping surface 51 is located on an upper surface of the rectangular block. The driving assembly 6 is arranged on the wall bed body 4. The locking member 7 is connected to the driving assembly 6. The locking member 7 has a bottom surface 71. When the wall bed body 4 is in an unfolded state, the wall bed body 4 is in a horizontal state, the driving assembly 6 drives the locking member 7 to extend into the self-locking stopper 5 and causes the bottom surface 71 of the locking member 7 to be located above the stopping surface 51 of the self-locking stopper 5, and the locking member 7 fits the self-locking stopper 5 to prevent storage of the wall bed body 4 in the wall bed cabinet 2 or prevents relative rotation between the wall bed body 4 and the wall bed cabinet 2.

Referring to FIGS. 2-7 again, the wall bed 1 having a self-locking function in this implementation, the self-locking stopper 5 is arranged on the wall bed cabinet 2, and the driving assembly 6 and the locking member 7 are arranged on the wall bed body 4. The bottom surface 71 of the locking member 7 is located above the stopping surface 51 of the self-locking stopper 5. If the wall bed cabinet 2 has a tendency to tip over towards the wall bed body 4, the wall bed cabinet 2 may be prevented from tipping over due to the blocking of the locking member 7 arranged on the wall bed body 4. At the same time, if the wall bed body 4 has a tendency to rotate upwards, the wall bed body 4 may be prevented from rotating upwards due to the blocking of the self-locking stopper 5 arranged on the wall bed cabinet 2. Therefore, the bottom surface 71 of the locking member 7 and the stopping surface 51 of the self-locking stopper 5 form a mutual self-locking structure. In the wall bed 1 having a self-locking function in this implementation, the bottom surface 71 of the locking member 7 and the stopping surface 51 of the self-locking stopper 5 are mutually self-locked to prevent the wall bed body 4 and the wall bed cabinet 2 from rotating relative to each other, thereby preventing tipping over of the wall bed cabinet 2 of the wall bed towards the wall bed body 4 due to insecure mounting or loosening.

The driving member 62 drives the locking member 7 to retract into the lock body 61, so that the bottom surface 71 of the locking member 7 is separated from the stopping surface 51 of the self-locking stopper 5, and the locking member 7 is unlocked from the self-locking stopper 5. In this case, the wall bed body 4 can be rotated upwards and folded into the wall bed cabinet 2. The driving member 62 is an L-shaped bar.

Referring to FIGS. 17 - 20, FIG. 17 is an exploded view of a second unlocking member and a gas spring according to the second implementation of this application, and FIGS. 18-20 are a schematic diagram of a folding process of the wall bed having a self-locking function. As shown in the figures, this implementation is different from the first implementation in that the wall bed 1 having a self-locking function in this implementation further includes a second unlocking member 12. The second unlocking member 12 is fixedly arranged on the gas spring 3, and is located at the pivotal end between the gas spring 3 and the wall bed body 4. In this implementation, the second unlocking member 12 has a slot 121 corresponding to the gas spring 3. A lower end of the second unlocking member 12 has a connecting hole 122. An upper end of the second unlocking member 12 has a protruding portion 123. The second unlocking member 12 is clamped to the other end of the gas spring 3 by using the slot 121, is pivotally connected to the wall bed body 4 together with the other end of the gas spring 3 by using the connecting hole 122, and is fixedly arranged on the gas spring 3. The protruding portion 123 is configured to push the other end of the driving member 62 away from the other side of the L-shaped chute 65. During storage of the wall bed body 4, the second unlocking member 12 pushes the other end of the driving member 62 away from the other side of the L-shaped chute 65. In other words, the second unlocking member 12 pushes the other end of the driving member 62 to slide from the vertical groove 652 to the horizontal groove 651. Moreover, when the other end of the driving member 62 is pushed to a junction between the vertical groove 652 and the horizontal groove 651, the elastic member 63 is reset and pushes the locking member 7 to extend out of the lock body 61, and the other end of the driving member 62 is driven to slide to a side of the horizontal groove 651 away from the vertical groove 652.

Referring to FIGS. 21 - 23 together with FIGS. 16, 21 - 23, are a schematic diagram of an unfolding process of the wall bed having a self-locking function according to the second implementation of this application. As shown in the figures, a side of the locking member 7 adjacent to the self-locking stopper 5 has a slope 72. The slope 72 is located on a left side of the locking member 7. The slope 72 has an angle relative to the bottom surface 71. During the unfolding of the wall bed body 4, the self-locking stopper 5 is in contact with the slope 72, and the locking member 7 is pushed by the slope 72 to move towards the inside of the lock body 61 and compress the elastic member 63. After the wall bed body 4 is fully unfolded, the elastic member 63 is reset and drives the other end of the driving member 62 to slide towards a side of the horizontal groove 651 away from the vertical groove 652. The driving member 62 drives the locking member 7 to extend out of the lock body 61, so that the locking member 7 extends into the self-locking stopper 5, and the bottom surface 71 of the locking member 7 abuts against the stopping surface 51 of the self-locking stopper 5.

Based on the above, this application provides a wall bed having a self-locking function, the self-locking stopper is arranged on the wall bed cabinet, and the driving assembly and the locking member are arranged on the wall bed body. When the wall bed is unfolded, the driving assembly drives the locking member to extend into the self-locking stopper and causes the bottom surface of the locking member to abut against the stopping surface of the self-locking stopper. Since the locking member and the self-locking stopper are mutually locked through the bottom surface and the stopping surface, the wall bed body and the wall bed cabinet are prevented from rotating relative to each other, thereby preventing tipping over of the wall bed cabinet of the wall bed towards the wall bed body due to insecure mounting or loosening. At the same time, in this application, the wall bed may also be disassembled into various parts and be carried and transported by a packaging case, which can greatly reduce a packaging volume and increase a loading capacity. After being transported to a designated position, various parts of the wall bed are assembled, which can lower transportation costs.
