Description

Technical Field

[0001] This invention relates to the field of crib technology, and more specifically, to a folding crib. Background Technology

[0002] The inventors discovered that existing baby folding beds generally have a locking mechanism. When the baby folding bed is unfolded, the locking mechanism is locked, keeping the baby folding bed stably unfolded. However, when the user needs to fold or close the baby folding bed, the user needs to unlock the locking mechanism first, and sometimes even unlock multiple parts, such as unlocking the bottom connecting rod and the top connecting rod, before folding the connecting rod and closing the baby folding bed. The operation is relatively troublesome and the folding efficiency is not high. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that existing folding beds are relatively cumbersome to operate and have low folding efficiency.

[0004] To solve the above-mentioned technical problems, the present invention provides a folding bed, the folding bed comprising:

[0005] Bottom folding rod assembly;

[0006] A base is provided at both ends of the bottom folding rod assembly, and at least one of the bases is provided with a rotating body, which is connected to the end of the bottom folding rod assembly and can rotate as the bottom folding rod assembly is folded;

[0007] A drive unlocking component, one end of which is connected to the rotating body and the other end of which is connected to the top folding rod assembly above, is used to be pulled towards the rotating body when the rotating body rotates to unlock the top folding rod assembly.

[0008] In one embodiment, the drive unlocking component includes a pull cord, one end of which is wound around the circumferential surface of the rotating body, and the other end is connected to a zipper mechanism of the top folding rod assembly. The zipper mechanism is used to automatically lock the top folding rod assembly and can be unlocked by the pull cord.

[0009] In one embodiment, the pull rope is built into the upright, and the two ends of the upright are respectively connected to the base and the top folding rod assembly.

[0010] In one embodiment, a channel is provided on the base, and the pull rope passes through the channel, the upright, and the top folding rod assembly, and is connected to the zipper mechanism.

[0011] In one embodiment, the top folding rod assembly includes two top connecting rods;

[0012] The zipper mechanism includes a lock seat and a second latch. The lock seat is connected to one of the top connecting rods and has a second lock hole. The second latch is connected to another of the top connecting rods and is connected to the pull rope. The second latch is inserted into the second lock hole. The pull rope is used to pull the second latch out of the second lock hole when force is applied.

[0013] In one embodiment, a pull-unlock mechanism is further included. The pull-unlock mechanism is mounted on the bottom folding rod assembly. The pull-unlock mechanism is used to lock the bottom folding rod assembly. Rotating the pull-unlock mechanism can unlock the bottom folding rod assembly. Pulling the pull-unlock mechanism can cause the bottom folding rod assembly to fold.

[0014] In one embodiment, the bottom folding rod assembly includes a middle folding rod assembly and two side folding rod assemblies. The middle folding rod assembly is located between the two side folding rod assemblies. Each end of the side folding rod assembly is connected to a base. The two bases located on the same side of the two side folding rod assemblies are connected by bottom edge rods. The middle folding rod assembly is connected between the two bottom edge rods. The lifting unlocking mechanism is mounted on the middle folding rod assembly.

[0015] In one embodiment, the pull-unlock mechanism includes a first base, a pull ring, a rotating shaft, a first locking tongue, and a bottom center rod. The bottom folding rod assembly is rotatably connected to the first base, the rotating shaft is rotatably disposed within the first base, the pull ring is connected to the top of the rotating shaft and is located at the top of the first base, and a first locking hole is provided on the rotating shaft.

[0016] The first locking tongue is connected to one end of the bottom center rod and can move along the length of the bottom center rod, while the other end of the bottom center rod is connected to the side folding rod assembly;

[0017] The first locking tongue has a through hole. The lifting unlocking mechanism also includes a second base, a locking guide rod, and a connecting rod. The two sides of the second base are respectively hinged to two folding rods of the bottom folding rod assembly through the connecting rod. The locking guide rod is vertically installed on the second base. The upper end of the locking guide rod is inserted into the guide channel of the first base along its length. The first locking tongue is sleeved on the locking guide rod through the through hole. The hole wall of the through hole is provided with a locking block. The locking block and the locking tongue are respectively located on both sides of the locking guide rod. In the locked state, the first locking tongue is inserted into the first locking hole, and the locking block is inserted into the locking groove on the surface of the locking guide rod.

[0018] When unlocking, rotating the pivot by the pull ring can drive the first locking tongue to move away from the pivot and disengage the locking block from the locking groove to release the mutual locking between the locking block and the locking groove. Thus, the pull ring can drive the pivot, the first base, and the bottom center rod to slide upward relative to the locking guide rod to fold the bottom folding rod assembly.

[0019] In one embodiment, the pull-unlock mechanism further includes a second torsion spring, which is mounted on the first base and disposed on the rotation axis of the pull ring. The second torsion spring is used to drive the pull ring to maintain a preset angle between it and the first base.

[0020] In one embodiment, the maximum length of the first bolt inserted into the first keyhole is greater than or equal to the maximum length of the lock block inserted into the lock groove.

[0021] In one embodiment, during unlocking, the pivot rotates, causing the lateral edge of the first lock hole to slide relative to the driving ramp of the front end of the first lock tongue, thereby driving the first lock tongue to move away from the pivot and causing the lock block to disengage from the lock groove.

[0022] A folding bed includes a bottom folding rod assembly, on which a lifting and unlocking mechanism is provided; the lifting and unlocking mechanism is used to lock the bottom folding rod assembly, and the bottom folding rod assembly can be folded by lifting the lifting and unlocking mechanism.

[0023] The lifting and unlocking mechanism includes a first base, and a pull ring is provided on the top of the first base. The pull ring is hinged to the top of the rotating shaft through a rotating shaft. A second torsion spring is sleeved on the rotating shaft. The second torsion spring is used to drive the pull ring to maintain a preset angle between it and the first base.

[0024] The beneficial effects of the folding bed provided by this invention include:

[0025] The user can unlock the bottom folding rod assembly by manually rotating the lifting unlocking mechanism, and then lift the mechanism again to fold the bottom folding rod assembly. As the bottom folding rod assembly rotates, a rotating body rotates with it, pulling the unlocking component towards the rotating body, thereby folding the top folding rod assembly. This achieves full unlocking and folding of the folding bed. The operation is simple and quick, efficiently and reliably converting the driving force generated by the rotation of the bottom folding rod assembly to drive the unlocking of the top folding rod assembly, ensuring efficient and reliable unlocking and folding.

[0051] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0052] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0053] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0054] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of this invention is usually placed, they are only for the convenience of describing this invention 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, and therefore should not be construed as a limitation of this invention.

[0055] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0056] It should be noted that, where there is no conflict, the features in the embodiments of the present invention can be combined with each other.

[0057] Please refer to Figure 1-Figure 2 This embodiment provides a folding bed 100, which includes a bottom folding rod assembly 1;

[0058] A base 5 is provided at both ends of the bottom folding rod assembly 1. At least one of the bases 5 is provided with a rotating body 11, which is connected to the end of the bottom folding rod assembly 1 and can rotate as the bottom folding rod assembly 1 is folded.

[0059] A drive unlocking component is provided, with one end connected to the rotating body 11 and the other end connected to the top folding rod group 6 above. The drive unlocking component is used to be pulled towards the rotating body 11 when the rotating body 11 rotates to unlock the top folding rod group 6.

[0060] Specifically, when the bottom folding rod assembly 1 rotates, the rotating body 11 rotates with the bottom folding rod assembly 1, pulling the unlocking component to move toward the rotating body 11, thereby unlocking the top folding rod assembly 6 and folding the top folding rod assembly 6, thus realizing the full unlocking and folding of the folding bed 100. The operation is simple and quick, and can efficiently and reliably convert the driving force generated by the rotation of the bottom folding rod assembly 1 to drive the unlocking of the top folding rod assembly 6. The unlocking and folding are efficient and reliable.

[0061] refer to Figure 8 , Figure 9 and Figure 13 In some embodiments, the drive unlocking component includes a pull cord 10, one end of which is wound around the circumferential surface of the rotating body 11, and the other end is connected to the zipper mechanism 9 of the top folding rod assembly 6. The zipper mechanism 9 is used to automatically lock the top folding rod assembly 6 and can be unlocked by the action of the pull cord 10.

[0062] Specifically, the zipper mechanism 9 can automatically lock the top folding rod assembly 6. When the bottom folding rod assembly 1 rotates relative to the base 5, the rotating body 11 rotates with the bottom folding rod assembly 1, thereby winding the pull rope and pulling the pull rope toward the rotating body 11, thus pulling the zipper mechanism 9 to unlock the top folding rod assembly 6. After unlocking, the top folding rod assembly 6 can be driven to fold freely downwards. The pull rope design is simple and low-cost, and can efficiently convert the driving force generated by the rotation of the bottom folding rod assembly 1 to drive the top folding rod assembly 6 to unlock.

[0063] refer to Figure 5 In some embodiments, the pull rope 10 is built into the upright 4, and the two ends of the upright 4 are respectively connected to the base 5 and the top folding rod group 6.

[0064] Specifically, the base 5 is located at the junction of the bottom folding rod assembly 1 and the upright 4, and the top folding rod assembly 6 is connected to the top of the upright 4. The pull rope is built into the upright 4, which ensures the overall structure is simple and protects the pull rope from being exposed to the outside and getting tangled and damaged.

[0065] refer to Figure 1 In some embodiments, a lifting unlocking mechanism 7 is also included. The lifting unlocking mechanism 7 is mounted on the bottom folding rod assembly 1 and is used to lock the bottom folding rod assembly 1. Rotating the lifting unlocking mechanism 7 can unlock the bottom folding rod assembly 1, and pulling the lifting unlocking mechanism 7 can drive the bottom folding rod assembly 1 to fold.

[0066] Specifically, when the bed is unfolded, the lifting unlocking mechanism 7 can lock the bottom folding rod assembly 1; when folding is required, first rotate the lifting unlocking mechanism 7 to unlock the bottom folding rod assembly 1, and then pull the lifting unlocking mechanism 7 to fold the bottom folding rod assembly 1. In this embodiment, the lifting unlocking mechanism 7 can lock the bed, and the bed can be unlocked and folded with a simple rotation and lifting operation, making the operation extremely simple and efficient.

[0067] Please see Figure 1 and Figure 2The bottom folding rod assembly 1 includes a central folding rod assembly 2 and two side folding rod assemblies 3. The central folding rod assembly 2 is located between the two side folding rod assemblies 3. Each end of a side folding rod assembly 3 is connected to a base 5. The two bases 5 located on the same side of the two side folding rod assemblies 3 are connected by bottom edge rods 1-1. The central folding rod assembly 2 is connected between the two bottom edge rods 1-1. A lifting unlocking mechanism 7 is installed on the central folding rod assembly 2. Thus, the lifting unlocking mechanism 7 is installed at the center of the bottom of the folding bed 100, reducing the possibility of accidental activation by external objects and improving the safety of the folding bed 100. Furthermore, the bottom structure of the bottom folding rod assembly 1 is more robust, ensuring the structural strength of the folding bed when unfolded.

[0068] Please see Figures 1 to 3 The lifting unlocking mechanism 7 includes a first base 71, a pull ring 73, a rotating shaft 74, a first torsion spring 76, a first locking tongue 77, a first return spring (not shown in the figure), a bottom center rod 79, and a second torsion spring 80. The bottom folding rod assembly 1 is rotatably connected to the first base 71. The rotating shaft 74 is vertically and rotatably disposed inside the first base 71. The pull ring 73 is connected to the top of the rotating shaft 74 and is located at the top of the first base 71. A first locking hole 75 is provided on the rotating shaft 74. The first torsion spring 76 is installed inside the first base 71 and sleeved on the rotating shaft 74. The first torsion spring 76 is used to drive the rotating shaft 74 to return to its original position.

[0069] The first locking tongue 77 is connected to one end of the bottom center rod 79 via a first return spring. The first locking tongue 77 is inserted into the bottom center rod 79 and can move along the length of the bottom center rod 79. In this way, the first locking tongue 77 is not easily touched by external objects and accidentally unlocked. Furthermore, when the first locking tongue 77 is driven to move away from the pivot 74, the first return spring can apply a reverse force to the first locking tongue 77 to make it press against the pivot 74, preventing the first locking tongue 77 from being pushed too far by the pivot 74 and separating too far from the pivot, thus preventing it from being unable to be inserted into the first lock hole 75 and reset when relocking is required.

[0070] One end of the bottom center rod 79 is connected to the first base 71, and the other end of the bottom center rod 79 is connected to the side folding rod group 3.

[0071] The first locking tongue 77 has a through hole 78. The lifting unlocking mechanism 7 also includes a second base 81, a locking guide rod 82, and a connecting rod 83. The two sides of the second base 81 are hinged to the two folding rods of the middle folding rod group 2 through the connecting rod 83. The folding rods are hinged to the first base 71. The locking guide rod 82 is vertically installed on the second base 81. The upper end of the locking guide rod 82 is inserted into the guide channel at the lower part of the first base 71 along the length direction. The first locking tongue 77 is sleeved on the locking guide rod 82 through the through hole 78. The hole wall of the through hole 78 is provided with a locking block 781. The locking block 781 and the first locking tongue 77 are respectively located on both sides of the rod body of the locking guide rod 82. In the locked state, the first locking tongue 77 is inserted into the first locking hole 75, and the locking block is inserted into the locking groove 821 on the surface of the rod body of the locking guide rod 82.

[0072] When unlocking, by rotating the pivot 74 via the pull ring 73, the lateral edge of the first lock hole 75 can push the first lock tongue 77 to move away from the pivot 74 through relative sliding with the driving inclined surface 771 at the front end of the first lock tongue 77 (when the pivot 74 rotates at a large angle, the first lock tongue 77 can even slide out of the first lock hole 75 on the pivot 74), and cause the lock block 781 to disengage from the lock groove 821, releasing the mutual locking between the lock block 781 and the lock groove 821, so that the bottom folding rod assembly 1 can be folded: when folding, pulling the pull ring 73 upward can drive the pivot 74, the first base 71, and the bottom center rod 79 to slide upward relative to the locking guide rod 82, thereby folding the entire bottom folding rod assembly 1.

[0073] In this embodiment, the locking groove 821 of the locking guide rod 82 cooperates with the locking block 781 on the wall of the through hole 78 to achieve mutual locking between the locking guide rod 82, the bottom center rod 79, and the first base 71; the connecting rods 83 on both sides are symmetrically arranged on both sides of the locking guide rod 82, and can rotate synchronously and at the same angle when folding. In addition, the locking guide rod 82 cooperates with the guide channel at the bottom of the first base 71 to ensure that the two folding rods of the middle folding rod group 2 rotate symmetrically, thereby ensuring that the folding bed is upright from left to right and preventing tilting or tipping during folding.

[0074] In this way, the lifting and unlocking mechanism 7 has a simple structure, reliable transmission, and is not prone to jamming. Moreover, it is easy to operate. Users can unlock and fold the folding bed 100 by turning and pulling the ring 73 with one hand.

[0075] Specifically, the maximum length of the first locking tongue 77 inserted into the first lock hole 75 is greater than or equal to the maximum length of the locking block 781 inserted into the lock groove 821. This ensures that the travel of the first locking tongue 77 is greater than or equal to the travel of the locking block 781. When the first locking tongue 77 is pushed to move away from the rotating shaft 74, there is sufficient distance for the locking block 781 to disengage from the lock groove 821, thereby releasing the mutual locking between the locking block 781 and the lock groove 821.

[0076] The diameter of the through hole 78 along the length of the first latch 77 minus the diameter of the locking guide rod 82 is greater than or equal to the maximum length by which the first latch 77 is inserted into the first lock hole 75. When the first latch 77 is pushed to move away from the pivot 74, there is sufficient clearance between the through hole 78 and the locking guide rod 82 for the first latch 77 to move, and there is also sufficient space for the lock block 781 to disengage from the lock groove 821 and unlock.

[0077] In some embodiments, the pull ring 73 is hinged to the top of the rotating shaft 74 via a rotating shaft. A second torsion spring 80 is sleeved on the rotating shaft, with one end connected to the surface of the rotating shaft and the other end connected to the first base 71. The second torsion spring 80 is used to drive the pull ring 73 to maintain a preset angle between it and the first base 71. Specifically, the elastic force of the second torsion spring can make the pull ring 73 form a certain angle with the first base 71, that is, stand upright on the surface of the first base 71. This can shorten the distance that the operator has to reach down to operate the pull ring 73, avoiding the problem that short people have difficulty touching the pull ring 73 from above when it is attached to the top surface of the first base 71, thus improving the user experience.

[0078] Furthermore, in other embodiments, the top surface of the first base 71 has a groove 72 (see [link]). Figure 1 Alternatively, the second torsion spring 80 can be configured to drive the pull ring 73 to be placed in the groove 72, which can then accommodate the pull ring 73. Thus, after the user releases the pull ring 73, it will automatically return to the groove 72 under the action of the second torsion spring 80.

[0079] Please see Figure 6 and Figure 7 The base 5 has a channel 51 through which the pull rope 10 passes, through the upright 4 and the top folding rod assembly 6, and connects to the zipper mechanism 9. This prevents the pull rope 10 from being exposed, thus preventing external objects from accidentally pulling the pull rope 10 and causing the zipper mechanism 9 to unlock accidentally.

[0080] Please see Figure 8 and Figure 9The top folding rod assembly 6 includes two top connecting rods 61; the zipper mechanism 9 includes a lock seat 91, a second latch 93, and a second return spring (not shown in the figure). The lock seat 91 is connected to one of the top connecting rods 61, and a second lock hole 92 is provided on the lock seat 91. The second latch 93 is connected to the other top connecting rod 61 and is connected to the pull rope 10. The second latch 93 is inserted into the interior of the top connecting rod 61. In this way, the second latch 93 is not easily touched by external objects and is not easily unlocked by accident.

[0081] The pull rope 10 is used to pull the second locking tongue 93 out of the second locking hole 92 when force is applied. The two ends of the second return spring are respectively connected to the second locking tongue 93 and the top connecting rod 61. The second return spring is used to drive the second locking tongue 93 into the second locking hole 92. In this way, the pull lock mechanism 9 has a simple structure, reliable transmission, and is not prone to jamming.

[0082] The working process of the folding bed 100 provided in this embodiment:

[0083] 1. Unlocking and folding process: Please refer to Figure 10 The user can unlock the bottom folding rod group 1 by manually rotating the lifting and unlocking mechanism 7. Lifting the lifting and unlocking mechanism 7 again will cause the bottom folding rod group 1 to fold. During the rotation of the bottom folding rod group 1 relative to the base 5, the rotating body 11 rotates with the bottom folding rod group 1 to pull the pull rope 10, unlocking the zipper mechanism 9, so that the top folding rod group 6 can be folded, thereby realizing the full unlocking and folding of the folding bed 100. The operation is simple and the folding is efficient.

[0084] 2. Unfolding process: The user moves the uprights 4 on both sides away from each other, which will cause the top folding rod group 6 and the bottom folding rod group 1 to unfold. When the top folding rod group 6 and the bottom folding rod group 1 are fully unfolded, the locking block 781 on the bottom folding rod group 1 will automatically insert into the locking groove 821 to lock the movement of the bottom folding rod group 1. The second locking tongue 93 on the top folding rod group 6 will automatically insert into the second locking hole 92 to lock the top folding rod group 6.

[0085] The beneficial effects of the folding bed 100 provided in this embodiment include:

[0086] 1. The user can unlock the bottom folding rod assembly 1 by manually rotating the lifting unlocking mechanism 7, and then lift the lifting unlocking mechanism 7 to fold the bottom folding rod assembly 1. During the rotation of the bottom folding rod assembly 1 relative to the base 5, the rotating body 11 rotates with the bottom folding rod assembly 1 to pull the pull rope 10, unlocking the zipper mechanism 9, and folding the top folding rod assembly 6, thereby realizing the full unlocking and folding of the folding bed 100. The operation is simple and quick, and can efficiently and reliably convert the driving force generated by the rotation of the bottom folding rod assembly 1 to drive the unlocking of the top folding rod assembly 6. The unlocking and folding are efficient and reliable.

[0087] 2. The lifting unlocking mechanism 7 and the zipper mechanism 9 have simple structures, reliable transmission, and are not prone to jamming.

[0088] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
