Description

Technical Field

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

[0002] In modern life, especially in spaces with limited space, such as small apartments, student dormitories, multi-functional hotel rooms, multi-functional offices in workplaces, hospital wards, and family entertainment rooms, the demand for multi-functional furniture is increasing. Existing convertible or folding beds are mostly limited to basic bed functions. While they offer folding or unfolding capabilities, they only provide basic rest and typically cannot simultaneously provide additional functions such as entertainment and storage. Similarly, entertainment features like ping-pong tables and pool tables often require separate spaces, are inconvenient to move once installed, occupy considerable space, and have low efficiency. They cannot meet diverse living needs within limited spaces. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a multifunctional convertible bed that can be transformed into a ping-pong table, a billiard table, a bed, and a basketball court. This greatly improves space utilization, ease of use, and sports experience. The bed and entertainment tabletop are shared in space, and the bed can be easily switched between different functions, bringing great convenience.

[0004] The technical problem to be solved by this utility model is achieved through the following technical solution: a multifunctional deformable bed includes a deformable modular box, a support device at the bottom of the modular box, a lifting mechanism for lifting the modular box in the middle of the support device, symmetrical side supports for flipping the modular box on both sides of the support device, and a flipping shaft that cooperates with the side supports on the side of the modular box. The lifting mechanism pushes the modular box upward to the flipping height. When the modular box is in its initial form, the top surface faces upward, and the top surface of the modular box is set as a ping-pong table surface, while the bottom surface of the modular box is set as a billiard table surface. When the modular box is rotated 180°, the bottom surface of the modular box faces upward to become a billiard table surface. The modular box, through the cooperation of the lifting mechanism and the side supports, flips and rotates to achieve rapid conversion between a ping-pong table and a billiard table.

[0005] The table tennis table surface includes a first panel and a second panel that are hinged together. The first panel and the second panel are laid flat. After the second panel is flipped along the first panel, it overlaps with the front of the first panel.

[0006] When the ping-pong tabletop of the modular unit is set horizontally upwards, the second panel flips over and engages with the free end of the first panel. The space below the initial position of the second panel serves as a storage compartment. Fixed side panels are located on both sides of the storage compartment, and the first side panel is hinged along the upper edge of the fixed side wall. The first side panels rotate towards each other and flatten to form a support for the folding mattress. A folding mattress, including a fixed pad and a flip pad, is located below the first panel. The flip pad is integrally formed with the back of the first panel. After flipping, the flip pad is horizontally aligned with the fixed pad, transforming into a bed frame. After transformation, it can be used as a master bed in the master bedroom, a ping-pong table, or in conjunction with an oval rotating dinner tray. It is suitable for family gatherings, company tea parties, and conference tables. With a storage compartment under the ping-pong tabletop, it integrates multiple functions—ping-pong table, billiards table, and bed—effectively utilizing space.

[0007] As a further embodiment of this invention, the first panel has two first bed boards on both sides that cover the flip-up pad, and a headboard between the two first bed boards. After the flip-up pad and the fixed pad are folded, the headboard covers the end of the fixed pad. A flip-up shaft is set on the headboard. Second bed boards are provided on both sides of the fixed pad, and a nursing table is provided between the end of the fixed pad and the headboard. The nursing table has legs at both ends, and the legs are hinged to the outer surface of the corresponding second bed board. The nursing table and adjustable legs provide additional value to the use of the bed. The nursing table can be used as a temporary work surface or dining table, making it convenient for users to perform some daily activities or nursing work in bed. The clever folding design of the flip-up pad and the fixed pad can effectively save space. When the nursing table is not needed, it can be folded or stowed away, so that the bed does not take up too much space, making it suitable for small spaces or environments that require flexible space utilization.

[0008] As a further embodiment of this invention, a hinge shaft is provided at the mating edge of the first and second bed boards on corresponding sides. The hinge shaft includes a first connecting groove plate and a second connecting groove plate. A shaft hole is provided at the mating point of the first and second connecting groove plates, and a hinge shaft passes through the shaft hole. The first connecting groove plate is secured to the first bed board body. Positioning holes are provided on all three sides of the first connecting groove plate, and positioning screws are installed in the positioning holes for fastening. The second connecting groove plate is secured to the second bed board body. Positioning holes are provided on all three sides of the second connecting groove plate, and positioning screws are installed in the positioning holes for fastening. By setting a hinge shaft and using a hinge shaft inserted through the shaft hole, the connection between the first and second bed boards becomes more stable, preventing them from coming undone due to repeated use during rotation. The hinge shaft effectively connects the two bed boards and drives their rotation or folding, increasing the structural stability and durability of the folding mattress.

[0009] As a further embodiment of this invention, a buffer gap is provided between the second bed board and the first side board. The buffer gap is in the form of an irregularly shaped mounting groove, with an L-shaped lower part. An irregularly shaped mounting plate of matching shape and size is installed within the groove. The matching of the irregularly shaped mounting groove and the mounting plate ensures precise positioning and docking of the components, making the connection between the bed board and the side board more reliable and aesthetically pleasing. The pre-reserved irregularly shaped mounting groove prevents interference during bed frame deformation.

[0010] As a further embodiment of this invention, the storage compartment is further equipped with a flipping device for automatically flipping the rotating plate. The flipping device includes a flipping motor and a flipping frame. The bottom of the flipping frame is hinged to the back panel of the billiard table, and the bottom of the flipping motor is also hinged to the back panel of the billiard table. The flipping motor shaft is hinged to the middle of the flipping frame, and a folding frame is hinged to the top edge of the flipping frame. A flipping hinge shaft is provided between the flipping frame and the folding frame, and bearing rollers extend from both ends of the flipping hinge shaft. The flipping device is installed in the storage compartment, effectively utilizing space. At the same time, the hinge structure between the flipping motor and the flipping frame, as well as the hinged connection between the motor shaft and the middle of the flipping frame, ensures flexible and stable flipping.

[0011] As a further embodiment of this invention, the folding frame is rotated 180° along the hinge axis and then aligned linearly with the flipping frame. A positioning groove is provided at the free end of the folding frame, and an external support rod is provided between the positioning groove and the free end of the flipping pad. Hooks are provided at both ends of the external support rod; one hook pulls the flipping pad, and the other hook pulls the inner groove. By rotating 180° and aligning the folding frame linearly with the flipping pad, a stable positioning state is maintained, preventing loosening or asymmetry during use and enhancing the stability and reliability of the device.

[0012] As a further embodiment of this invention, the storage compartment includes a folding headboard frame. The folding headboard frame includes two folding arms hinged to the outer wall of the fixed side panel. The two folding arms are arranged in parallel, and a connecting plate is located at the top of each arm. The connecting plate has an L-shaped hinge lug perpendicular to the connecting plate, which hinges to a background panel. A handle is located on the background panel. The parallel arrangement of the two folding arms and their hinge to the outer wall of the fixed side panel ensures the stability and sturdiness of the headboard frame after folding. The connecting plate and the L-shaped hinge lug work together to fold and unfold the background panel, facilitating storage. The handle allows for easy pushing and pulling of the background panel, simplifying operation.

[0013] The headboard consists of a main board with extension boards on both sides. Several butterfly hinges are installed along the length of the main board between the extension boards and the sides of the main board. The extension boards on both sides of the main board and the butterfly hinges between the extension boards and the sides of the main board ensure a smoother and more stable folding or unfolding of the headboard. The butterfly hinges distribute mechanical stress, preventing structural deformation caused by single-point hinges.

[0014] As a further embodiment of this invention, the support device includes a frame-shaped base with four legs, each leg having a caster wheel at its bottom. A lifting mechanism is located in the center of the frame-shaped base; the lifting mechanism is a central scissor lift with a lifting platform at its top, on which the assembled housing rests. The central scissor lift smoothly adjusts the height of the lifting platform. Through evenly distributed force, swaying or tilting during the lifting process is effectively avoided.

[0015] The side supports are located at both ends of the frame base. The side supports include side positioning plates that can be stored in the frame base and a rotating frame. After the side positioning plates are flipped, they coincide with the end frame of the frame base and widen the frame of the frame base. The side positioning plates are stored by flipping and are flipped for support when in use, which effectively utilizes space and achieves stable support.

[0016] The rotating frame includes a first support and a second support, which are hinged together. A right-angle folding chain is provided between the lower part of the first support and the frame base. After the right-angle folding chain is unfolded, the first support and the second support are flipped together to a vertical support state. The second support is flipped to a vertical state again. Both the first support and the second support are provided with limiting baffles at the bottom. The free end of the first support is provided with a V-shaped groove frame that rotates with the flipping shaft.

[0017] The hinged connection between the first and second supports, combined with the unfolding function of the right-angle folding chain, allows the first and second supports to be flipped together to a vertical support state. The flipping process is simple and efficient, and the operation is convenient and smooth. The limiting baffle effectively prevents the support from excessive rotation or displacement during the flipping process. The flipping shaft can flip freely in the V-groove frame, and the lifting control effectively separates it from the support.

[0018] As a further embodiment of this invention, the combined housing is flipped up to be vertically positioned on a ping-pong table using a lifting mechanism and a side support. The back of the second panel is designed as a basketball panel, with retractable hooks on the basketball backboard. When the basketball backboard is vertical, a basketball hoop for shooting is hooked onto the retractable hooks. Within a limited space, it can be transformed into a basketball panel as needed. The retractable hooks do not interfere with the transformation process, allowing for flexible assembly and disassembly of the basketball hoop.

[0019] The beneficial effects of this utility model are:

[0020] This utility model provides a multifunctional convertible bed, including a deformable modular box. A support device is provided below the modular box, and a lifting mechanism for raising and lowering the modular box is provided in the middle of the support device. Side supports for flipping the modular box are symmetrically provided on both sides of the support device. A flipping shaft that cooperates with the side supports is provided on the side of the modular box. The lifting mechanism pushes the modular box upward to the flipping height. When the modular box is in its initial form, the top surface is facing upward, and the top surface of the modular box is set as a ping-pong table, while the bottom surface of the modular box is set as a billiard table. The modular box can be rotated 180°, and the bottom surface of the modular box is facing upward to become a billiard table. The modular box can be flipped and rotated through the cooperation of the lifting mechanism and the side supports to quickly transform between a ping-pong table and a billiard table.

[0021] The table tennis table features a storage compartment underneath, integrating multiple functions such as a table tennis table, a billiards table, a bed, and a basketball court. This greatly improves space utilization, ease of use, and the sports experience. The bed and entertainment table share space and can be switched between different functions with simple operation, bringing great convenience. Attached Figure Description

[0039] Example 1

[0040] like Figures 1 to 3 As shown, a multifunctional convertible bed includes a deformable modular box 4, a support device 1 at the bottom of the modular box, a lifting mechanism 2 for lifting the modular box in the middle of the support device, and side supports 3 symmetrically arranged on both sides of the support device for flipping the modular box. The side supports can be hidden and folded. The support device includes a frame-shaped base 102, and four legs 101 are provided on the four feet of the frame-shaped base 102. Each leg is provided with a universal wheel 111 at the bottom. The support device can be manually pushed to move the modular box as a whole.

[0041] The lifting mechanism 2 is located in the middle of the frame base. The lifting mechanism is a middle scissor lift. The top of the middle scissor lift is equipped with a lifting platform 201, and the combined box is placed on the lifting platform.

[0042] In use, activate the lifting platform 201. The lifting platform rises, driving the combined container upwards, suspending the combined container in the air. The height avoids the maximum height when the side supports are open, facilitating the opening of the side supports.

[0043] The side brackets 3 are set at both ends of the frame base. The side brackets include a side positioning plate 302 that can be stored in the frame base and a rotating frame. After the side positioning plate is flipped, it coincides with the end frame of the frame base and widens the frame of the frame base.

[0044] First, flip the side positioning plate and support it on the end frame to widen and support the end frame.

[0045] The rotating frame includes a first support 303 and a second support 304, which are hinged together. A right-angle folding chain 301 is provided between the lower part of the first support and the frame base. After the right-angle folding chain is unfolded, the first support and the second support are flipped together to a vertical support state. The second support is flipped to a vertical state again. Both the first support and the second support are provided with a limiting baffle 331 at the bottom. The limiting baffle 331 limits the position. After the second support is rotated open, it forms a straight support with the first support. The first support is vertically set on the end frame.

[0046] After the second bracket rotates and opens, it forms a straight support with the first bracket. The free end of the first bracket is provided with a V-shaped groove 305 that rotates with the flip shaft. The side of the combined box is provided with a flip shaft that cooperates with the side bracket. Handles 402 are provided on both sides of the flip shaft. The lifting mechanism pushes the combined box upward to the flip height. The lifting mechanism 2 is activated, and the lifting platform moves downward, driving the combined box to move downward synchronously. The flip shaft falls to the bottom of the V-shaped groove. The lifting platform continues to move downward. The combined box is completely supported by the rotating frames on both sides. The combined box can be manually pushed to rotate circumferentially along the flip shaft 401. The rotation stops when it reaches the horizontal or vertical direction. Depending on the actual needs, it can be flipped onto the ping-pong table or rotated in the opposite direction to the billiard table.

[0047] Restart the lifting mechanism 2. After the lifting platform rises, it supports the combined box again and continues to rise, avoiding the space where the rotating frame retracts. Rotate the second bracket 304 and fold it with the first bracket 303. Then retract the second bracket 304 into the frame base.

[0048] Next, the lifting mechanism is moved downwards, and the lifting platform is moved downwards until it reaches the usable height of a ping-pong table, billiard table, or bed.

[0049] Example 2

[0050] like Figure 5 As shown, when the combined cabinet is in its initial state, with the top surface facing upwards, the top surface of the combined cabinet is set as a ping-pong table surface 5. The lifting mechanism 2 is activated to adjust the height, synchronously adjusting the height of the combined cabinet to 76cm for the ping-pong table surface. Fine-tuning can be made according to the user's height to achieve optimal usability.

[0051] Example 3

[0052] like Figure 4 As shown, the bottom of the modular housing is designed as a billiard table. Rotating the housing 180° so the bottom faces upwards, the height is adjusted using lifting mechanism 2, simultaneously raising and lowering the housing to a height of 81cm for the billiard table. Fine-tuning can be made to accommodate users of different heights for optimal use. Alternatively, the height can be adjusted according to industry standards or user preferences.

[0053] Example 4

[0054] The ping-pong table surface 5 includes a first panel 502 and a second panel 501 that are hinged to each other. The first panel and the second panel are in a flat state. After the second panel is flipped along the first panel, it is set perpendicular to the front of the first panel. It can meet the needs of one user to practice ping-pong.

[0055] Example 5

[0056] like Figures 10-11 As shown, the ping-pong table surface 5 includes a first panel 502 and a second panel 501 that are hinged to each other. The first panel and the second panel are in a flat state. After the second panel is flipped along the first panel, it overlaps with the front of the first panel.

[0057] When the ping-pong tabletop 5 of the combined box is set horizontally upward, the second panel flips over and engages with the free end of the first panel. The space below the initial position of the second panel is set as a storage compartment 15. Fixed side panels 405 are provided on both sides of the storage compartment. The first side panel 406 is hinged to the upper edge of the fixed side wall. The first side panels rotate in opposite directions and flatten to form a support plate for the folding mattress. A folding mattress is provided below the first panel. The folding mattress includes a fixed pad 433 and a flipping pad 404. The flipping pad is integrally set with the back of the first panel.

[0058] like Figure 12 As shown, the first panel has two first bed boards 441 on both sides that wrap the flip pad, and a headboard between the two first bed boards. After the flip pad and the fixed pad are folded, the headboard wraps the end of the fixed pad. A flip shaft is set on the headboard, and a second bed board 433 is provided on both sides of the fixed pad.

[0059] A connecting hinge shaft 12 is provided at the mating edge of the first bed board 441 and the second bed board 433 on the corresponding side. The connecting hinge shaft includes a first connecting groove plate 13 and a second connecting groove plate 10. A shaft hole is provided at the mating point of the first connecting groove plate and the second connecting groove plate. A hinge shaft passes through the shaft hole. The first connecting groove plate is clamped on the first bed board body. Positioning holes are provided on all three sides of the first connecting groove plate. Positioning screws 11 are provided in the positioning holes for fastening. The second connecting groove plate is clamped on the second bed board body. Positioning holes are provided on all three sides of the second connecting groove plate. Positioning screws are provided in the positioning holes for fastening.

[0060] A buffer gap is provided between the second bed board and the first side board. The buffer gap is in the form of an irregularly shaped mounting groove 431. The lower part of the irregularly shaped mounting groove is L-shaped, and an irregularly shaped mounting plate 14 with a matching shape and size is provided inside the irregularly shaped mounting groove. The irregularly shaped mounting plate is manually removed to free up operating space in the irregularly shaped mounting groove.

[0061] Manually flip the flipping pad to align it horizontally with the fixed pad, transforming it into a bed frame. Activate the lifting mechanism to adjust the height, simultaneously adjusting the height of the combined housing. The optimal bed frame height is 60cm. The bed frame height can be adjusted according to industry standards or user preferences.

[0062] A nursing table 434 is provided between the end of the fixed pad and the headboard. The nursing table has table legs 432 at both ends, and the table legs are respectively hinged to the outer surface of the second bed board on the corresponding side.

[0063] During use, the nursing table 434 is rotated and opened along the table legs to a horizontal position, and the nursing table is used as a temporary work surface or a dining table. At this time, there is a limit stop 16 on the outer panel of the second bed board, and the table legs rest against the limit stop to ensure that the nursing table will not tip over and remains in a horizontal position.

[0064] It allows users to perform daily activities or caregiving tasks in bed. When not in use, the care table can be folded or stowed away, so the bed doesn't take up too much space, making it suitable for small spaces or environments that require flexible space utilization.

[0065] Example 6

[0066] The space enclosed by the first bed board and the headboard is provided with a first tray to support the flipping pad, and a second tray to support the fixing pad is provided between the two second bed boards. The flipping pad and the fixing pad can be removed together, and teaching aids or toys for demonstration, teaching or entertainment can be placed on the first tray and the second tray.

[0067] Activate the lifting mechanism and side support to rotate the horizontally positioned bed 90° to a vertical position. Suspend a television, blackboard, or other display screen on the first tray for leisure and entertainment.

[0068] Example 7

[0069] like Figure 6 As shown, the storage compartment 15 is also equipped with a flipping device 9 that drives the flipping plate to flip automatically. The flipping device includes a flipping motor 901 and a flipping frame 902. The flipping motor is connected to an external power source through a wire. After power is turned on, the flipping motor is started and the flipping motor shaft performs telescopic movement.

[0070] The bottom of the flip frame 902 is hinged to the back plate of the billiard table, the bottom of the flip motor body is also hinged to the back plate of the billiard table, the flip motor shaft is hinged to the middle of the flip frame, the top edge of the flip frame is hinged to a folding frame 903, a flip hinge shaft is provided between the flip frame and the folding frame, and bearing rollers 904 extend from both ends of the flip frame.

[0071] When the 404 flip pad needs to be automatically flipped, the flip motor is started, the flip motor shaft extends, and the flip frame rotates upward. After the bearing roller contacts the basketball panel, it rolls along the basketball panel, driving the flip pad to rotate upward, so that patients can sit up by leaning on it during use.

[0072] The rotating motor shaft retracts, driving the rotating frame to rotate back. After the bearing roller 904 contacts the basketball panel, it rolls along the basketball panel, driving the rotating pad to rotate downwards back to its initial position.

[0073] When it is necessary to rotate the flip pad to the vertical direction, the folding frame 903 is rotated 180° along the hinge axis and then arranged in a straight line with the flip frame. The free end of the folding frame 903 is provided with a positioning groove 905. An external support rod 906 is provided between the positioning groove and the free end of the flip pad. Hooks are provided at both ends of the external support rod. One end hooks pull the flip pad and the other end hooks the inner groove.

[0074] When the flipping pad flips over to the fixed pad, it is hooked and pulled by the external support rod 906, and slowly laid down and folded with the fixed pad.

[0075] During use, if the patient is using it independently without a caregiver, it is convenient for them to sit up. The flipping motor is connected to the controller, which is wirelessly connected to a remote control. The patient can control the flipping motor with the remote control, causing the motor shaft to extend and drive the flipping frame to rotate upwards. After the bearing rollers contact the basketball panel, they roll along the basketball panel, driving the flipping pad to rotate upwards, allowing the patient to sit up using the flipping pad. Once the desired position is reached, the patient can stop the flipping motor by controlling it with the remote control.

[0076] When the patient wants to lie flat, they can restart the flipping motor by controlling it with the remote control. The flipping motor shaft retracts, driving the flipping frame to rotate back. After the bearing roller 904 contacts the basketball panel, it rolls along the basketball panel, driving the flipping pad to rotate downwards back to the initial position.

[0077] Example 8

[0078] like Figures 8-9As shown, the storage compartment 15 is provided with a folding headboard 8. The folding headboard includes a folding arm 801 that is hinged to the outer wall of the fixed side panel. The two folding arms are arranged in parallel. The top of the two folding arms is provided with a connecting plate 802. The connecting plate is provided with an L-shaped hinge 803 that is perpendicular to the connecting plate. The L-shaped hinge is hinged to a background plate. The background plate is provided with a handle.

[0079] Pull the handle to move the backdrop 804; the two folding arms rotate along the hinge point, pulling the backdrop, which is placed horizontally in the storage compartment, into a vertical position. A limiting baffle is provided on the fixed side panel to prevent the folding arms from moving, ensuring the backdrop remains vertical after being flipped upwards for use.

[0080] like Figure 13 As shown, the background plate 804 includes a main board 841, extension plates 842 on both sides of the main board, and a number of butterfly hinges 843 along the length direction between the extension plates and the sides of the main board. When all the butterfly hinges on both sides are fastened, the extension plates are laid flat, forming a plane with the main board.

[0081] When in use, a pre-made soft cushion is placed on the background board as decoration and a backrest, which looks beautiful and has practical value at the same time.

[0082] When the bed is transformed into a ping-pong table, the flipping motor is activated. The motor shaft extends, driving the flipping frame to rotate upwards. The bearing rollers contact the basketball court panel and roll along it, driving the flipping pad to rotate upwards. The flipping pad continues to rotate to a vertical position and is then hooked by the external support rod 906, causing it to flip towards the fixed pad and slowly fold down with it.

[0083] Then rotate the first side panel to a vertical position, making it an integral part of the fixed side wall, and deform it to form a storage compartment. First, use the handle to pull the background panel 804, and the two folding arms will rotate downwards along the hinge point to retract the vertically placed background panel into the storage compartment.

[0084] Then flip the second panel away from the first panel, so that the first and second panels are laid flat, and it is transformed into a ping-pong table surface again.

[0085] Example 9

[0086] like Figure 7 As shown, the combined box is flipped to be vertically set on the ping-pong table surface 5 by the cooperation of the lifting mechanism 2 and the side bracket 3. The back of the second panel is set as a basketball panel 7. The basketball panel is provided with a retractable hook 701. The retractable hook uses a plug-in dovetail groove. When the basketball panel is vertically set, a basketball hoop 702 for shooting is hooked on the retractable hook.

[0087] Adjust the lifting mechanism to raise or lower the combined box to the usable height, open the retractable hook, hook the basketball hoop onto the retractable hook, and shoot.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
