Description

Technical Field

[0001] This application relates to a type of furniture, and more particularly to a wall bed with a self-locking function. Background Technology

[0002] In modern living environments, storage and comfort are emphasized. In densely populated cities and countries, storage and organization are no longer limited to everyday items. Furthermore, because living spaces are often limited, people are making the most of their limited space. Therefore, people typically strive to arrange their living environment more efficiently. The bed is an essential household item. However, beds usually take up a significant amount of space, leading to the development of foldable wall beds as a way to create more living space.

[0003] Please see Figure 1 This is a schematic diagram of the current wall bed structure. As shown in the figure, the current wall bed S typically consists of a wall bed cabinet and a wall bed frame. One side of the wall bed frame is connected to the wall bed cabinet via a connecting rod assembly S11 installed inside the wall bed cabinet, achieving a rotatable connection. The other side of the wall bed frame can rotate around its rotatable connection side to the wall bed cabinet, enabling the wall bed frame to unfold and retract. In the process of developing this application, the applicant discovered that the current wall bed S lacks a self-locking structure between the wall bed cabinet and the wall bed frame. When the wall bed cabinet is not securely installed or is loose, the wall bed cabinet may veer towards the wall bed frame (e.g., as shown in the figure). Figure 1 The risk of tipping over (as shown in the tilt direction) poses a significant safety hazard to the wall bed S. Summary of the Invention

[0004] This application provides a wall bed with a self-locking function, which solves the problem of wall bed cabinets tipping over due to insecure or loose installation.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: A wall bed with a self-locking function is provided, comprising a wall bed cabinet, a gas spring, a wall bed frame, a self-locking stop, a drive assembly, and a locking element. One end of the gas spring is pivotally connected to the upper part of the wall bed cabinet. One end of the wall bed frame is pivotally connected to the other end of the gas spring. When the wall bed frame is retracted, the pivot end of the wall bed frame and the gas spring moves towards the bottom of the wall bed cabinet, and the other end of the wall bed frame flips upward around its pivot end with the gas spring and is retracted into the wall bed cabinet. The self-locking stop is fixedly mounted on the wall bed cabinet. The self-locking stop corresponds to the wall bed frame. The self-locking stop has a stop surface. The drive assembly is mounted on the wall bed frame. The locking element is connected to the drive assembly. The locking element has a bottom surface. When the wall bed is in the unfolded state, the wall bed is in a horizontal state. The drive assembly drives the locking member to extend into the self-locking stop, and the bottom surface of the locking member abuts against the stop surface of the self-locking stop. The locking member and the self-locking stop prevent the wall bed and the wall bed cabinet from rotating relative to each other.

[0006] In one embodiment, the drive assembly includes a lock body, a drive member, and an elastic member. The lock body is fixed to the wall bed frame and has a first side and a second side opposite to each other. The first side is located near the self-locking stop and has an opening. One end of the drive member passes through the second side and is connected to the locking member. The elastic member is disposed between the locking member and the second side. When the wall bed frame is in an unfolded state, the elastic member is in a reset state. When the drive member drives the locking member to retract the lock body, the elastic member is in an elastic state.

[0007] In one embodiment, the lock body is provided with screw holes, and the lock body is fixed to the side tube of the wall bed frame by screws.

[0008] In one embodiment, the drive assembly includes an L-shaped slide groove, with the other end of the drive member located within the L-shaped slide groove. The wall bed is in an unfolded state, and the other end of the drive member is located on one side of the L-shaped slide groove. When the wall bed is unlocked, the other end of the drive member is driven to slide to the other side of the L-shaped slide groove. The drive member drives the locking member to retract into the lock body, causing the bottom surface of the locking member to separate from the abutting surface of the self-locking stop.

[0009] In one embodiment, it further includes: an unlocking member, which is fixedly disposed on the gas spring and located at the pivot end between the gas spring and the wall bed body. During the wall bed body retraction process, the unlocking member pushes the other end of the driving member away from the other side of the L-shaped slide groove, and the elastic member resets and pushes the locking member out of the lock body.

[0010] In one embodiment, the unlocking member has a slot corresponding to the gas spring, the lower end of the unlocking member has a connecting hole, the upper end of the unlocking member has a protrusion, the unlocking member is engaged with the other end of the gas spring via the slot, and is pivotally connected to the wall bed body together with the other end of the gas spring via the connecting hole, and is fixedly mounted on the gas spring. The protrusion is configured to push the other end of the driving member away from the other side of the L-shaped slide groove.

[0011] In one embodiment, it further includes: a support leg tube and a zipper cable, one end of the support leg tube is pivotally connected to the other side of the wall bed body, one end of the zipper cable is connected to the other end of the drive member, and the other end of the zipper cable is wrapped around the pivot end between the support leg tube and the wall bed body. When the wall bed body is in the unfolded state, the support leg tube is located at the lower end of the wall bed body and supports the wall bed body. When the support leg tube rotates upward around its pivot end with the wall bed body, the support leg tube drives the locking member to retract into the lock body through the zipper cable, so that the bottom surface of the locking member separates from the abutting surface of the self-locking stop.

[0012] In one embodiment, the side of the locking member adjacent to the self-locking stop has an inclined surface with an angle relative to the bottom surface. During the unfolding of the wall bed, the self-locking stop contacts the inclined surface, which pushes the locking member toward the interior of the lock body and compresses the elastic member.

[0013] In one embodiment, the self-locking stop is a U-shaped stop, with the abutting surface located on the upper surface of the U-shaped stop.

[0014] In this embodiment, a self-locking stop is provided on the wall bed cabinet, and a drive assembly and a locking component are provided on the wall bed frame. When the wall bed is unfolded, the drive assembly drives the locking component to extend into the self-locking stop, and the bottom surface of the locking component abuts against the abutting surface of the self-locking stop. Since the locking component and the self-locking stop are mutually locked through their bottom surfaces and abutting surfaces, the relative rotation of the wall bed frame and the wall bed cabinet is prevented, thus preventing the wall bed cabinet from tipping over towards the wall bed frame due to insecure installation or looseness.

Detailed Implementation

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] In the description of this application, it should be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0018] In addition, although the terms “first,” “second,” etc. are used in this article to describe different components, these terms are only used to distinguish components or operations described with the same technical terms.

[0019] Please see Figures 2 to 8 , Figure 2 This is a perspective view of the unfolded state of the wall bed with self-locking function according to the first embodiment of this application. Figure 3 It is a 3D image of the folded-up state. Figures 4 to 8This is a schematic diagram of the folding process; as shown in the figure, the wall bed 1 with self-locking function in this embodiment includes a wall bed cabinet 2, a gas spring 3, a wall bed body 4, a self-locking stop 5, a drive assembly 6, and a locking component 7. One end of the gas spring 3 is pivotally connected to the upper part of the wall bed cabinet 2. The other end of the gas spring 3 is pivotally connected to one end of the wall bed body 4. When the wall bed body 4 is folded up, the pivot end of 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 flips upward around its pivot end with the gas spring 3 and is folded into the wall bed cabinet 2. The gas spring 3 is a component that can realize functions such as support, buffering, braking, height and angle adjustment. Since the gas spring 3 is a conventional structure in this field, it will not be described in detail here.

[0020] See also Figure 4 and Figure 5 As shown, the self-locking stop 5 is fixedly installed on the wall bed cabinet 2. The self-locking stop 5 corresponds to the wall bed frame 4; here, "corresponds" means that the self-locking stop 5 is located on one side of the wall bed frame 4, such as... Figure 4 As shown, the self-locking stop 5 is located on the left side of the wall bed body 4. The self-locking stop 5 has an abutment surface 51. In this embodiment, the self-locking stop 5 is a U-shaped stop, and the abutment surface 51 is located on the upper surface of the U-shaped stop. The drive assembly 6 is disposed on the wall bed body 4. The locking member 7 is connected to the drive assembly 6. The locking member 7 has a bottom surface 71. When the wall bed body 4 is in the unfolded state, the wall bed body 4 is in a horizontal state. The drive assembly 6 drives the locking member 7 to extend into the self-locking stop 5, and the bottom surface 71 of the locking member 7 abuts against the abutment surface 51 of the self-locking stop 5. The locking member 7 and the self-locking stop 5 cooperate with each other to prevent the wall bed body 4 from rotating relative to the wall bed cabinet 2.

[0021] The self-locking wall bed 1 of this embodiment is provided with a self-locking stop 5 on the wall bed cabinet 2 and a drive assembly 6 and a locking member 7 on the wall bed body 4. The bottom surface 71 of the locking member 7 abuts against the abutting surface 51 of the self-locking stop 5. If the wall bed cabinet 2 has a tendency to tilt towards the wall bed body 4, the blocking of the locking member 7 on the wall bed body 4 will prevent the wall bed cabinet 2 from tilting. At the same time, if the wall bed body 4 has a tendency to rotate upward, the blocking of the self-locking stop 5 on the wall bed cabinet 2 will prevent the wall bed body 4 from rotating upward. Therefore, the bottom surface 71 of the locking member 7 and the abutting surface 51 of the self-locking stop member 5 form a mutually self-locking structure. In this embodiment, the wall bed 1 with self-locking function prevents the relative rotation of the wall bed body 4 and the wall bed cabinet 2 by mutually locking the bottom surface 71 of the locking member 7 and the abutting surface 51 of the self-locking stop member 5, thus preventing the wall bed cabinet 2 from tipping over towards the wall bed body 4 due to insecure installation or looseness.

[0022] The following is a more detailed description of the wall bed 1 with self-locking function according to this embodiment: Please refer to Figures 9 to 11 See also Figure 4 and Figure 5 As shown, Figure 9 This is a perspective view of the driving component and locking member according to the first embodiment of this application. Figure 10 It is a sectional view diagram and Figure 11 yes Figure 10 A schematic diagram of its operation is shown; as shown, the drive assembly 6 includes a lock body 61, a drive member 62, and an elastic member 63. The lock body 61 is fixed to the wall bed frame 4. In this embodiment, the lock body 61 is provided with a screw hole 611. The lock body 61 is fixed to the wall bed frame 4 by screws 612 threaded through the frame side tube 41 of the wall bed frame 4 and threaded into the screw hole 611. This reduces the installation space and improves the concealment of the drive assembly 6, preventing children from easily unlocking it and improving the product's safety level. The lock body 61 has a first side 601 and a second side 602. The first side 601 is located on the side closer to the self-locking stop 5, such as... Figure 10 As shown, the first side 601 is located on the left side of the lock body 61, and the second side 602 is located on the right side of the lock body 61. The first side 601 is provided with an opening 613, which is used for the locking member 7 to extend and retract within the lock body 61. One end of the driving member 62 passes through the second side 602 and is connected to the locking member 7. An elastic member 63 is disposed between the locking member 7 and the second side 602. The elastic member 63 is a spring, which is fitted onto the driving member 62. When the wall bed body 4 is in the extended state, the elastic member 63 is in the reset state. When the driving member 62 drives the locking member to retract into the lock body 61, the elastic member 63 is in an elastic state and has a tendency to push the locking member 7 out of the lock body 61.

[0023] As stated above, please refer to the following: Figure 4 and Figure 5 As shown, the drive assembly 6 includes an L-shaped groove 64. One side of the L-shaped groove 64 (horizontal groove 641) extends along the length of the wall bed body 4, and the other side is located away from the locking member 7 and extends upward (vertical groove 642). The other end of the drive member 62 is located within the L-shaped groove 64. The wall bed body 4 is in an unfolded state, and the other end of the drive member 62 is located on one side of the L-shaped groove 64, as shown... Figure 5 As shown, the other end of the drive member 62 is located on the side of the horizontal groove 641 away from the vertical groove 642. When the wall bed body 4 is unlocked, it drives the other end of the drive member 62 to slide to the other side of the L-shaped slide groove 64; in other words, the other end of the drive member 62 slides into the vertical groove 642. The drive member 62 drives the locking member 7 to retract the lock body 61, causing the bottom surface 71 of the locking member 7 to separate from the abutting surface 51 of the self-locking stop 5. The locking member 7 and the self-locking stop 5 are unlocked, and at this time the wall bed body 4 can rotate upward and retract into the wall bed cabinet 2. The drive member 62 is an L-shaped rod.

[0024] Please see Figure 12See also Figures 6 to 8 As shown, Figure 12 This is an exploded view of the unlocking member and gas spring according to the first embodiment of this application; as shown, the wall bed 1 with self-locking function also includes an unlocking member 8. The unlocking member 8 is fixedly mounted on the gas spring 3 and located at the pivot end between the gas spring 3 and the wall bed body 4. In this embodiment, the unlocking member 8 has a slot 81 corresponding to the gas spring 3. The lower end of the unlocking member 8 has a connecting hole 82. The upper end of the unlocking member 8 has a protrusion 83. The unlocking member 8 is engaged with the other end of the gas spring 3 via the slot 81, and is pivotally connected to the wall bed body 4 together with the other end of the gas spring 3 via the connecting hole 82, and is fixedly mounted on the gas spring 3. The protrusion 83 is configured to push the other end of the drive member 62 away from the other side of the L-shaped slide groove 64. During the folding of the wall bed frame 4, the unlocking member 8 pushes the other end of the driving member 62 away from the other side of the L-shaped slide groove 64. In other words, the unlocking member 8 pushes the other end of the driving member 62 to slide from the vertical groove 642 to the horizontal groove 641. When the other end of the driving member 62 is pushed to the junction of the vertical groove 642 and the horizontal groove 641, the elastic member 63 resets and pushes the locking member 7 to extend out of the lock body 61, while simultaneously causing the other end of the driving member 62 to slide towards the side of the horizontal groove 641 away from the vertical groove 642.

[0025] Please see Figures 13 to 15 See also Figure 9 As shown, Figures 13 to 15 This is a schematic diagram of the unfolding process of the self-locking wall bed according to the first embodiment of this application; as shown, the side of the locking member 7 adjacent to the self-locking stop member 5 has an inclined surface 72. The inclined surface 72 is located on the left side of the locking member 7. The inclined surface 72 has an angle with the bottom surface 71. During the unfolding process of the wall bed body 4, the self-locking stop member 5 contacts the inclined surface 72, and pushes the locking member 7 towards the inside of the lock body 61 and compresses the elastic member 63 via the inclined surface 72. After the wall bed body 4 is fully unfolded, the elastic member 63 resets and drives the other end of the driving member 62 to slide towards the side of the horizontal groove 641 away from the vertical groove 642. 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 stop member 5, and the bottom surface 71 of the locking member 7 abuts against the abutting surface 51 of the self-locking stop member 5.

[0026] Please see Figures 16 to 18 , Figure 16 This is a schematic diagram of the unfolded state of the wall bed with self-locking function according to the second embodiment of this application. Figure 17 This is a diagram illustrating the flipping of the support leg tube. Figure 18This is a three-dimensional view showing the connection of the drive assembly, locking element, and zipper cable. As shown in the figure, the difference between this embodiment and the first embodiment is that, in addition to the wall bed cabinet 2, gas spring 3, wall bed body 4, self-locking stop 5, drive assembly 6, and locking element 7, the wall bed 1 with self-locking function in this embodiment also includes support legs 9 and zipper cable 10. One end of the support legs 9 is pivotally connected to the other side of the wall bed body 4. One end of the zipper cable 10 is connected to the other end of the drive assembly 62, and the other end of the zipper cable 10 is wrapped around the pivot end between the support legs 9 and the wall bed body 4. When the wall bed body 4 is in the unfolded state, the support legs 9 are located at the lower end of the wall bed body 4 and support the wall bed body 4. When the support leg tube 9 rotates upward around its pivot point with the wall bed body 4, it winds the other end of the zipper cable 10. In this way, the zipper cable 10 drives the locking member to retract into the lock body 61, so that the bottom surface 71 of the locking member 7 separates from the abutting surface 51 of the self-locking stop member 5.

[0027] In summary, this application provides a wall bed with a self-locking function. This is achieved by installing a self-locking stop on the wall bed cabinet and a drive assembly and a locking component on the wall bed frame. When the wall bed is unfolded, the drive assembly drives the locking component to extend into the self-locking stop, causing the bottom surface of the locking component to abut against the abutting surface of the self-locking stop. Because the locking component and the self-locking stop are mutually locked through their bottom surfaces and abutting surfaces, relative rotation between the wall bed frame and the wall bed cabinet is prevented, thus preventing the wall bed cabinet from tipping over towards the wall bed frame due to insecure installation or looseness.
