Description

Folding baby crib

[0001] The present application claims priority to the Chinese patent application No. 2024104730628, filed on April 19, 2024, and titled "Folding baby crib", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of baby products, in particular to a folding baby crib. BACKGROUND

[0003] A baby crib refers to a bed specially used for infants and young children, which can provide a comfortable and safe sleeping environment for the baby. Compared with a fixed-structure baby crib, a folding baby crib can better meet various use scenarios such as use, storage, and transportation, as it can be flexibly switched between an unfolded and a folded structure, and thus is more popular among families.

[0004] However, the structure of the folding baby crib in the related art is complex, and it is difficult for a user to unfold or fold the baby crib, and the experience is not good. Moreover, the volume of the folded baby crib is still large, and it occupies too much storage space.

[0005] SUMMARY

[0006] Therefore, it is necessary to provide a folding baby crib to solve the problems of complex structure, large operation difficulty, and large storage space occupation in the prior art.

[0007] The present application provides a folding baby crib, which comprises:

[0008] an upper crib enclosure, the upper crib enclosure comprising a first upper enclosure rod set, a joint lock, and a second upper enclosure rod set, the first upper enclosure rod set being rotatably connected with the second upper enclosure rod set through the joint lock, and the joint lock having a locked state for locking the first upper enclosure rod set and the second upper enclosure rod set, and an unlocked state for releasing the first upper enclosure rod set and the second upper enclosure rod set;

[0009] an unlocking switch, the unlocking switch being arranged on the first upper enclosure rod set and the second upper enclosure rod set, and the unlocking switch being controllably connected with the joint lock to control the joint lock to switch between the locked state and the unlocked state;

[0010] a crib leg mechanism, the crib leg mechanism comprising a first crib leg assembly and a second crib leg assembly, an upper end of the first crib leg assembly being connected with the first upper enclosure rod set, and an upper end of the second crib leg assembly being connected with the second upper enclosure rod set; and

[0011] The lower bed enclosure comprises a first lower rail group, a folding joint and a second lower rail group, one end of the first lower rail group is rotationally connected with the lower end of the first bed leg assembly, the other end of the first lower rail group is rotationally connected with one end of the second lower rail group through the folding joint, and the other end of the second lower rail group is rotationally connected with the lower end of the second bed leg assembly;

[0012] The locking state of the joint lock corresponds to the unfolded state of the folding baby crib; when the joint lock is in the unlocked state, the first upper rail group and the second upper rail group are flipped downward and folded together, the first lower rail group and the second lower rail group are flipped upward and folded together, and the first bed leg assembly and the second bed leg assembly move towards each other.

[0013] The folding baby crib has an unfolded state (i.e. a use state) and a folded state (i.e. a non-use state). When the folding baby crib is in the unfolded state, the joint lock is in the locked state. At this time, the joint lock locks the first upper rail group and the second upper rail group, and the first upper rail group and the second upper rail group maintain a horizontal posture away from each other. At the same time, the first bed leg assembly and the second bed leg assembly, as well as the first lower rail group and the second lower rail group, all maintain an unfolded posture away from each other. The folding baby crib maintains an unfolded frame structure, thereby facilitating use. When the folding baby crib is not needed, the user operates the unlocking switch to unlock the joint lock. The joint lock releases the first upper rail group and the second upper rail group. Then the user presses the upper bed enclosure downward and pulls the lower bed enclosure upward. At this time, the first upper rail group and the second upper rail group are flipped downward and move towards each other synchronously, and the first lower rail group and the second lower rail group are flipped upward and move towards each other synchronously. Until the first upper rail group and the second upper rail group, as well as the first lower rail group and the second lower rail group, are folded together, the first bed leg assembly and the second bed leg assembly also move towards each other under the pulling of the upper bed enclosure and the lower bed enclosure. Thus, the folding baby crib is folded into a compact square structure, which has a small volume and occupies less space, thereby facilitating storage and transportation. When the folding baby crib needs to be used again, the first bed leg assembly and the second bed leg assembly are pulled in opposite directions, respectively. Thus, the first upper rail group and the second upper rail group, as well as the first lower rail group and the second lower rail group, are pulled and flipped to be unfolded. The first upper rail group and the second upper rail group are locked again by the joint lock. The structure of the entire folding baby crib is simple, the unfolding and folding operations are convenient and labor-saving, the implementability is strong, and the use experience of the user is improved.

[0024] Referring to FIG. 1, FIG. 3 and FIG. 4, a folding baby crib 100 is shown in an embodiment of the present application, specifically, only the bed main structure part of the folding baby crib 100 is shown in FIG. 1, and the rest of the bed board, bed mattress and other components are not shown in the figure, but this does not constitute a limitation on the scope of protection of the present application.

[0025] Exemplarily, the folding baby crib 100 includes an upper bed enclosure 10, an unlocking switch 20, a bed leg mechanism 30 and a lower bed enclosure 40. Among them, the upper bed enclosure 10 is connected with the lower bed enclosure 40 through the bed leg mechanism 30 to form the main structure of the folding baby crib 100, which plays a role in supporting and loading the rest of the components and bearing the weight of the baby. In this embodiment, the folding baby crib 100 in the unfolded state is in the shape of a rectangular frame structure, of course, in other embodiments, the folding baby crib 100 can also be in the shape of a sphere, an egg type, etc.

[0026] In the present application, the upper bed enclosure 10 includes a first upper enclosure rod group 11, a joint lock 12 and a second upper enclosure rod group 13, the first upper enclosure rod group 11 is rotatably connected with the second upper enclosure rod group 13 through the joint lock 12, and the joint lock 12 has a locking state of locking the first upper enclosure rod group 11 and the second upper enclosure rod group 13, and an unlocking state of releasing the first upper enclosure rod group 11 and the second upper enclosure rod group 13; the unlocking switch 20 is arranged on the first upper enclosure rod group 11 and the second upper enclosure rod group 13, and the unlocking switch 20 is controllably connected with the joint lock 12 to control the joint lock 12 to switch between the locking state and the unlocking state.

[0027] Further, the bed leg mechanism 30 includes a first bed leg assembly 31 and a second bed leg assembly 32, the upper end of the first bed leg assembly 31 is connected with the first upper enclosure rod group 11, and the upper end of the second bed leg assembly 32 is connected with the second upper enclosure rod group 13; the lower bed enclosure 40 includes a first lower enclosure rod group 41, a folding joint 42 and a second lower enclosure rod group 43, one end of the first lower enclosure rod group 41 is rotatably connected with the lower end of the first bed leg assembly 31, the other end of the first lower enclosure rod group 41 is rotatably connected with one end of the second lower enclosure rod group 43 through the folding joint 42, and the other end of the second lower enclosure rod group 43 is rotatably connected with the lower end of the second bed leg assembly 32.

[0028] The locking state of the joint lock 12 corresponds to the unfolded state of the folding baby crib 100; when the joint lock 12 is in the unlocked state, the first upper surrounding rod group 11 and the second upper surrounding rod group 13 are flipped downward and folded close, the first lower surrounding rod group 41 and the second lower surrounding rod group 43 are flipped upward and folded close, and the first bed leg assembly 31 and the second bed leg assembly 32 move toward each other.

[0029] In summary, the implementation of the technical scheme of the embodiment has the following beneficial effects: the folding baby crib 100 has an unfolded state (i.e. a use state) and a folded state (i.e. a non-use state). When the folding baby crib 100 is in the unfolded state, the joint lock 12 is in the locked state. At this time, the joint lock 12 locks the first upper surrounding rod group 11 and the second upper surrounding rod group 13, and the first upper surrounding rod group 11 and the second upper surrounding rod group 13 maintain a horizontal pose away from each other. Meanwhile, the first bed leg assembly 31 and the second bed leg assembly 32, as well as the first lower surrounding rod group 41 and the second lower surrounding rod group 43, all maintain an unfolded pose away from each other. The folding baby crib 100 maintains an unfolded frame structure, thereby facilitating use.

[0030] When the folding baby crib 100 is not needed for use, the unlocking switch 20 is operated to unlock the joint lock 12. The joint lock 12 releases the first upper surrounding rod group 11 and the second upper surrounding rod group 13. Immediately thereafter, the user presses down the upper crib surrounding 10 while pulling the lower crib surrounding 40 upward. At this time, the first upper surrounding rod group 11 and the second upper surrounding rod group 13 are flipped downward and close to each other synchronously, and the first lower surrounding rod group 41 and the second lower surrounding rod group 43 are flipped upward and close to each other synchronously. Until the first upper surrounding rod group 11 and the second upper surrounding rod group 13, as well as the first lower surrounding rod group 41 and the second lower surrounding rod group 43, are folded close to each other. The first bed leg assembly 31 and the second bed leg assembly 32 also move toward each other under the pulling of the upper crib surrounding 10 and the lower crib surrounding 40, thereby making the folding baby crib 100 fold into a compact square structure, which has a small volume and occupies less space, thereby facilitating storage and transportation.

[0031] When the folding baby crib 100 needs to be used again, the first bed leg assembly 31 and the second bed leg assembly 32 are pulled in opposite directions, respectively, so as to pull and flip the first upper surrounding rod group 11 and the second upper surrounding rod group 13, as well as the first lower surrounding rod group 41 and the second lower surrounding rod group 43, to unfold. The first upper surrounding rod group 11 and the second upper surrounding rod group 13 are locked by the joint lock 12 again. The structure of the entire folding baby crib 100 is simple, the unfolding and folding operations are convenient and labor-saving, the implementability is strong, and the use experience of the user is improved.

[0032] Please continue to refer to Figure 1, on the basis of the above embodiment, the first upper rail group 11 and the second upper rail group 13 each include an upper connecting rod 11a, a first upper rail 11b, a second upper rail 11c, a first connecting joint 11d and a second connecting joint 11e. One end of the upper connecting rod 11a is rotatably connected with the first upper rail 11b through the first connecting joint 11d, and the other end of the upper connecting rod 11a is rotatably connected with the second upper rail 11c through the second connecting joint 11e.

[0033] That is, it can be understood that the first upper rail group 11 and the second upper rail group 13 adopt the same structure design, which helps to reduce the design and manufacturing cost, and makes the folding baby bed 100 obtain a more regular and consistent shape.

[0034] Two upper connecting rods 11a are each provided with an unlocking switch 20, and two first upper rails 11b are connected with a joint lock 12, and two second upper rails 11c are connected with a joint lock 12.

[0035] When the folding baby bed 100 needs to be folded, two unlocking switches 20 on both sides are operated at the same time, so that the two joint locks 12 are unlocked synchronously, and then the first upper rail group 11 and the second upper rail group are pressed down, and the two first upper rails 11b and the two second upper rails 11c are synchronously turned down with the rotating connection of the first connecting joint 11d and the second connecting joint 11e as the fulcrum, and in the turning process, the two first upper rails 11b and the two second upper rails 11c are gradually rotated and close to each other until they are close to each other, thus completing the folding operation of the upper bed rail 10.

[0036] In another embodiment, the first upper rail 11b and the second upper rail 11c are each provided as a hollow pipe. For example, the first upper rail 11b and the second upper rail 11c adopt a hollow circular pipe, which can reduce the weight of the folding baby bed 100 and reduce the manufacturing cost. Of course, in other embodiments, the first upper rail 11b and the second upper rail 11c can also adopt a solid rod.

[0037] Please continue to refer to FIG. 1 and FIG. 2, the unlocking switch 20 includes a switch body 21, a pull rope 22 and a sliding block 23, the switch body 21 is connected with one end of the pull rope 22, the other end of the pull rope 22 is connected with the sliding block 23; the joint lock 12 includes a shell 121 and a stopper 122, the stopper 122 is arranged in the shell 121, the shell 121 is rotationally connected with the opposite end of the two first upper surrounding rods 11b, the shell 121 is rotationally connected with the opposite end of the two second upper surrounding rods 11c, the sliding block 23 is slidably arranged in the cavity of the first upper surrounding rod 11b and the second upper surrounding rod 11c; in the locked state, the sliding block 23 extends out of the first upper surrounding rod 11b and the second upper surrounding rod 11c and abuts against the stopper 122; in the unlocked state, the switch body 21 pulls the sliding block 23 to retract into the interior of the first upper surrounding rod 11b and the second upper surrounding rod 11c through the pull rope 22, so that the sliding block 23 is separated from the stopper 122.

[0038] When it is needed to switch the folding baby crib 100 from the unfolded state for use to the folded state, it is only needed to press the switch body 21, the switch body 21 slides and synchronously pulls the pull rope 22, so that the pull rope 22 can further synchronously pull the sliding block 23, the sliding block 23 retreats from the outside to the cavity of the first upper surrounding rod 11b and the second upper surrounding rod 11c (in the locked state, at least part of the sliding block 23 extends out of the cavity and is clamped with the stopper 122), the sliding block 23 is separated from the stopper 122 to realize the unlocking of the joint lock 12, the first upper surrounding rod 11b and the second upper surrounding rod 11c obtain the rotational freedom degree of the opposite rotation, so as to be flipped and folded. That is to say, compared with the existing unlocking structure, the present scheme only needs to complete one pressing operation of the switch body 21 during the unlocking operation, which is simple, convenient and labor-saving.

[0039] It can be understood that the two first upper surrounding rods 11b each extend with the sliding block 23, the two sliding blocks 23 are simultaneously clamped or separated from the corresponding one stopper 122; the two second upper surrounding rods 11c each extend with the sliding block 23, the two sliding blocks 23 are simultaneously clamped or separated from the corresponding other stopper 122.

[0040] Further, the unlocking switch 20 further comprises an elastic reset member, which is arranged in the cavity of the first upper surrounding rod 11b and the second upper surrounding rod 11c, and one end of the elastic reset member is connected with the sliding block 23, and the other end of the elastic reset member is fixed to the side wall of the cavity. When the sliding block 23 is pulled back into the cavity of the first upper surrounding rod 11b and the second upper surrounding rod 11c, the elastic reset member is compressed and deformed by the sliding block 23. When the folding baby crib 100 is switched from the folded state to the unfolded state again, as soon as the first upper surrounding rod 11b and the second upper surrounding rod 11c are unfolded to the horizontal position, the elastic reset member outputs an elastic pushing force to the sliding block 23, so as to push the sliding block 23 to quickly extend out of the cavity and be re-coupled with the blocking block 122, thereby completing the automatic locking of the upper bed surrounding 10, and improving the automation level and user experience of the folding baby crib 100.

[0041] Optionally, the elastic reset member can be, but is not limited to, any one of a spring, an elastic column, an elastic sheet and the like.

[0042] Please continue to refer to FIG. 2. In another embodiment, the sliding block 23 is provided with a clamping step 231, which comprises a positioning surface 231a in the vertical direction and a buckling surface 231b in the horizontal direction. When the clamping step 231 is coupled with the blocking block 122, the positioning surface 231a abuts against the vertical side surface of the blocking block 122, and the buckling surface 231b is buckled on the horizontal top surface of the blocking block 122.

[0043] The sliding block 23 extends out of the lumen under the pushing of the elastic reset member, and is positioned by the abutment of the positioning surface 231a and the vertical side surface of the blocking block 122, so as to form a cooperative positioning of the sliding block 23 and the blocking block 122, thereby limiting the freedom degree of the first upper surrounding rod 11b and the second upper surrounding rod 11c in the horizontal direction. At the same time, the buckling surface 231b is buckled above the horizontal top surface of the blocking block 122, further restricting the freedom degree of the first upper surrounding rod 11b and the second upper surrounding rod 11c in the vertical direction relative to the blocking block 122, that is, ensuring that the first upper surrounding rod 11b and the second upper surrounding rod 11c cannot be accidentally folded downward, the joint lock 12 remains in the locked state, thereby ensuring that the folding baby crib 100 is in the unfolded state and the structure is stable and reliable.

[0044] Please continue to refer to FIG. 1 and FIG. 2, and in addition, on the basis of any of the above embodiments, the folding baby crib 100 further comprises a synchronous mechanism 50, one end of the synchronous mechanism 50 is rotatably connected with the first upper surrounding rod group 11, and the other end of the synchronous mechanism 50 is rotatably connected with the second upper surrounding rod group 13. In the length direction of the folding baby crib 100, the first upper surrounding rod group 11, the first bed foot assembly 31 and the first lower surrounding rod group 41 on the left side constitute a left side bed main body, and the second upper surrounding rod group 13, the second bed foot assembly 32 and the second lower surrounding rod group 43 on the right side constitute a right side bed main body. By arranging the synchronous mechanism 50, the action of the left side bed main body and the right side bed main body can be kept synchronous and consistent during the turning and unfolding or folding operation.

[0045] Specifically, in one embodiment, the synchronous mechanism 50 comprises a first supporting rod 51, a synchronous gear set and a second supporting rod 52, one end of the first supporting rod 51 is rotatably connected with the first upper surrounding rod group 11, the other end of the first supporting rod 51 is connected with the synchronous gear set, the synchronous gear set is connected with one end of the second supporting rod 52, and the other end of the second supporting rod 52 is rotatably connected with the second upper surrounding rod group 13, and the synchronous gear set is rotatably arranged in the housing 121.

[0046] The first supporting rod 51 and the second supporting rod 52 are respectively connected with the first upper surrounding rod group 11 and the second upper surrounding rod group 13 to realize the installation and fixation of the synchronous mechanism 50; the synchronous gear set has rotational freedom and rotates stably, and has a synchronous keeping effect on the left side bed main body and the right side bed main body when the left side bed main body and the right side bed main body are turned and unfolded or folded, thereby avoiding asynchronous action to affect the unfolding and folding effect.

[0047] Further, the synchronous gear set comprises a first fixed gear 53, a first movable gear 54, a second movable gear 55 and a second fixed gear 56, the first fixed gear 53 is engaged with the first movable gear 54, the first movable gear 54 is engaged with the second movable gear 55, the second movable gear 55 is engaged with the second fixed gear 56, the first fixed gear 53 is fixedly connected with the first supporting rod 51, and the second fixed gear 56 is fixedly connected with the second supporting rod 52. When the left side bed main body and the right side bed main body are relatively rotated, the first movable gear 54 is engaged and rotated with the first fixed gear 53 and the second movable gear 55 at the same time, and the second movable gear 55 is engaged and rotated with the first movable gear 54 and the second fixed gear 56 at the same time, the first fixed gear 53 and the second fixed gear 56 gradually rotate close to each other (cooperating with the folding baby crib 100 folding structure) or gradually rotate away from each other (cooperating with the folding baby crib 100 unfolding structure), which neither interferes with the structure switching of the folding baby crib 100, nor has good rotation adaptability, and the transmission ratio of the gear engagement is stable, avoiding the generation of slip phenomenon, and better constraining the rotation asynchronous phenomenon of the left side bed main body and the right side bed main body, thereby ensuring the synchronism of the action.

[0048] Of course, other embodiments of the above-mentioned gear set can also be replaced by a transmission ratio stable mechanism such as a synchronous belt wheel, a synchronous two-wheel, etc., which will not be described here.

[0049] Please continue to refer to FIG. 1 and FIG. 3, in addition, in still another embodiment, the lower bed enclosure 40 further comprises a linkage rod 44, both ends of the linkage rod 44 are connected with a corresponding bed folding joint 42 respectively. Specifically, the first lower enclosure rod set 41 and the second lower enclosure rod set 43 each comprise a first lower enclosure rod and a second lower enclosure rod, the two first lower enclosure rods are rotationally connected through a bed folding joint 42, the two second lower enclosure rods are rotationally connected through another bed folding joint 42, when the folding baby crib 100 is in the unfolded state, the two first lower enclosure rods and the two second lower enclosure rods are in the same horizontal plane, when the folding baby crib 100 is in the folded state, the two first lower enclosure rods and the two second lower enclosure rods are synchronously flipped upward until they are folded together; during this movement process, the linkage rod 44 can ensure the synchronization of the movement of the first lower enclosure rod set 41 and the second lower enclosure rod set 43, while enhancing the overall structural strength and rigidity of the lower bed enclosure 40, and improving the load capacity of the folding baby crib 100.

[0050] In order to facilitate the movement of the folding baby crib 100 when it is in the unfolded state for use, in an embodiment, the bottom of the first bed leg assembly 31 and the second bed leg assembly 32 is each provided with a caster 60. Specifically, the first bed leg assembly 31 and the second bed leg assembly 32 each comprise two bed leg pipes, a total of four bed leg pipes are arranged in a rectangular structure in the horizontal plane, and each bed leg pipe is provided with a caster 60 at the bottom, thereby further improving the support stability and movement flexibility.

[0051] In order to enable the folding baby crib 100 to be stably stopped at the use location, the caster 60 is provided with a brake 60a. The brake 60a can be manually controlled or controlled by stepping, which can be flexibly selected according to actual needs.

[0052] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the description.

[0053] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are all within the protection scope of the present application.
