Description

Technical Field

[0001] The present invention relates to the technical field of baby products, and more specifically to a baby bed that can be easily folded and stored.

Background Art

[0002] A baby bed is a fairly common baby-related product suitable for providing a comfortable sleeping environment for a baby. Generally, a baby bed includes components such as a bed body for placing a baby, a frame for supporting the bed body, and a cloth cover laid on the frame. Here, the frame includes an upper frame surrounding the activity and lying range of the baby, a leg frame supported on the ground, and a side rod connected to the upper frame and the leg frame. When a baby is using it, the connection between the upper frame, the side rod, and the leg frame is in a locked state to prevent the entire baby bed from moving, being disturbed by an external force, or falling due to the baby's turning over or rolling.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, after the baby has finished using it, the user needs to unlock the locked connection points one by one in the above-mentioned locked state to change the upper frame, the side rod, and the leg frame to a movable state with respect to each other, and then the baby bed can be folded and stored, but the procedure is complicated and time-consuming. Also, when a parent holds the baby in the baby bed with one hand, the above frame cannot be stored and folded with one hand, and the storage operation cannot be performed unless the parent places the baby in another place, further reducing the usability of the baby bed.

Embodiments for Carrying Out the Invention

[0031] Next, embodiments of the present invention will be described with reference to the accompanying drawings. Similar component numbers in the accompanying drawings represent similar components.

[0032] At least one object of the embodiments of the present invention is to provide a baby bed that can be easily folded and stored.

[0033] Referring to Fig. 1, Fig. 1 is a perspective schematic view of the first embodiment of the baby bed of the present invention. The baby bed 1 of this embodiment is suitable for accommodating infants. When the user wants to use the baby bed 1, the baby bed 1 can be deployed to the deployed state shown in Fig. 1. On the other hand, when the user finishes using the baby bed 1, the baby bed 1 can be folded and stored in the storage state as shown in Fig. 10. Thereby, the space in the user's room can be saved when the baby bed 1 is not in use. Also, in this embodiment, in order to prevent the baby bed 1 from being accidentally folded due to external force disturbance during use or inadvertent collision by the user, causing the infant to be accidentally injured, the baby bed 1 further has a locking function for locking the deployed state and an unlocking function for releasing the above locking state.

[0034] Specifically, the baby bed 1 includes a housing 10 including an upper frame 100, a lower frame 200, and side rods 300, a locking mechanism 20, and an unlocking mechanism 30. Here, the upper frame 100 can be regarded as the handrail of the baby bed and includes a first lateral portion 110, at least one first longitudinal portion 120, and at least one first pivoting portion 130. In this embodiment, the number of the first longitudinal portions 120 is two, which are arranged opposite to each other, and these first longitudinal portions 120 are respectively pivoted to both ends of the first lateral portion 110 via the first pivoting portions 130. The lower frame 200 can be regarded as the base of the baby bed frame and includes a second lateral portion 210, at least one second longitudinal portion 220, and at least one second pivoting portion 230. In this embodiment, the number of the second longitudinal portions 220 is also two, which are respectively pivoted to both ends of the second lateral portion 210 via the second pivoting portions 230 on both sides. Moreover, each second pivoting portion 230 has an upright portion 232, and an appropriate distance can be maintained between the lower frame 200 and the ground as the support legs of the baby bed 1. The side rods 300 are connected to the first pivoting portion 130 and the second pivoting portion 230 such that the upper frame 100 and the lower frame 200 face each other. The locking mechanism 20 is arranged on the first longitudinal portion 120, and the unlocking mechanism 30 is arranged on the first lateral portion 110.

[0035] As shown in FIG. 1, the upper frame 100 and the lower frame 200 each form a rectangle. The length of the first lateral portion 110 is shorter than the length of the first longitudinal portion 120, and the length of the second lateral portion 210 is shorter than the length of the second longitudinal portion 220. In other words, the unlocking mechanism 30 of the baby bed 1 is provided on the short side of the handrail of the bed frame, which is the long side portion of the folded bed frame. Thereby, the length occupied by the baby bed 1 in the room after being folded can be shortened.

[0036] On the one hand, the first vertical portion 120 includes a first pipe member 122 and a second pipe member 124, and the locking mechanism 20 is connected between the first pipe member 122 and the second pipe member 124. Specifically, the locking mechanism 20 of this embodiment is switchable between a locked state and an unlocked state. When the locking mechanism 20 is in the locked state, the first pipe member 122 and the second pipe member 124 are fixed to the locking mechanism 20. When the locking mechanism 20 is in the unlocked state, the first pipe member 122 and the second pipe member 124 are rotatable with respect to the locking mechanism 20. The operating mechanism of this part will be described later.

[0037] The second vertical portion 220 correspondingly includes a third pipe member 222 and a fourth pipe member 224 with respect to the first vertical portion 120, and the third pipe member 222 and the fourth pipe member 224 are pivotally attached to each other. Preferably, the lower frame 200 includes at least one third pivot portion 240 connected between the third pipe member 222 and the fourth pipe member 224, and a bottom pipe 250 arranged parallel to the second lateral portion 210. One end of the bottom pipe 250 is connected to the third pivot portion 240. In this embodiment, the lengths of the first pipe member 122 and the second pipe member 124 are substantially equal, and the lengths of the third pipe member 222 and the fourth pipe member 224 are also substantially equal. In other words, the baby bed 1 becomes in a semi-folded state from the unfolded state in FIG. 1 to the stored state in FIG. 10. Such a design not only makes the left-right symmetry beautiful, but also the center of gravity position of the baby bed 1 is stable during the folding process, which is advantageous for the user's one-handed operation and folding.

[0038] Preferably, the baby bed 1 further includes at least one carrier 40, which is, for example, a flexible lining, disposed between the second lateral portion 210, the second longitudinal portion 220, and the bottom tube 250, and supports the infant to lie on its side. When it is necessary to store the baby bed 1, the housing 10 can be directly folded without removing the carrier 40, which is very simple and convenient. Of course, in addition to supporting the infant with a flexible lining, the carrier 40 can also select a highly rigid plate-like material to enhance the support strength of the bottom of the baby bed 1, and a soft and thick mat can be laid on the upper part to make the infant comfortable when lying on its side. The present invention is not limited to this.

[0039] Referring to FIG. 2, FIG. 2 is a partially enlarged schematic view of the upper frame in FIG. 1. As shown, the first pivoting portion 130 includes an upper cover portion 132 and a lower cover portion 134 externally fitted to the first tube member 122 of the first lateral portion 110 and the first longitudinal portions 120 on both sides. The lower cover portion 134 is externally fitted to the first lateral portion 110, the upper cover portion 132, and the side rod 300. In other words, the first pivoting portion 130 restricts the first longitudinal portion 120 to be able to rotate only through the axis of the first lateral portion 110. Preferably, the first lateral portion 110 includes a tube body 112 formed with a positioning post 112a, a pivoting groove G is formed in the lower cover portion 134, and the positioning post 112a is slidably provided in the pivoting groove G. When the baby bed 1 is in the unfolded state as shown in FIG. 2, the positioning post 112a is located at the lower end portion of the pivoting groove G (the end portion close to the side rod 300). When the baby bed 1 is folded into the storage state as shown in FIG. 10, the positioning post 112a rotates to the upper end portion of the pivoting groove G (the end portion away from the side rod 300) together with the first lateral portion 110. Such a design can not only restrict the rotation direction of the first longitudinal portion 120, but also define the rotation stroke of the first tube member 122 through the positioning post 112a and the pivoting groove G, avoiding excessive unfolding or folding of the baby bed 1.

[0040] Hereinafter, the locking mechanism and unlocking mechanism of the baby bed 1 of this embodiment will be described in detail. Referring to FIGS. 3 to 10, FIGS. 3 to 6 are respectively schematic cross-sectional views of the unlocking mechanism of FIG. 2 and the locking and unlocking states of the unlocking mechanism of FIG. 1, FIG. 7 is a schematic view of the unlocking and folding storage of the upper frame of FIG. 1, FIG. 8 is a partially enlarged schematic view of the lower frame of FIG. 1, and FIGS. 9 and 10 are respectively perspective schematic views of the baby bed during folding storage and complete folding storage. As shown in FIGS. 3 and 4, the locking mechanism 20 includes a lock case 21, a position limiting member 22, and a connecting member 23. Here, the position limiting member 22 is tubular and fixed to the lock case 21, and the connecting member 23 is slidably provided in the hollow portion of the position limiting member 22. Further, the unlocking mechanism 30 includes an unlocking case 31, an operating member 32, at least one driving member 33, and at least one positioning member 34. Here, at least one position limiting portion 31a and an accommodation hole A are formed in the unlocking case 31. The operating member 32 is formed through the accommodation hole A, and at least one chute S is formed in the operating member 32. The positioning member 34 is, for example, a positioning pin and is slidably provided in the position limiting portion 31a and the chute S. The driving member 33 is, for example, a cable, and a part of it is embedded in the first lateral direction portion 110 and is connected to the positioning member 34.

[0041] On one hand, the first pipe member 122 includes an actuator 122a, a positioning portion 122b, and a return elastic member 122c. Here, the actuator 122a is disposed at one end where the first pipe member 122 is connected to the locking mechanism 20, and the driving member 33 is connected to the actuator 122a. The positioning portion 122b is, for example, a sheath of the driving member 33 and is fixed to the first pipe member 122. The return elastic member 122c is, for example, a linear spring and is connected between one end close to the first pivoting portion 130 of the actuator 122a and the positioning portion 122b. In other words, the driving member 33 is connected to the operating member 32 and the actuator 122a via the positioning member 34, and the operating member 32 is connected to the locking mechanism 20 via the driving member 33. Preferably, the locking mechanism 20 further includes an interlocking elastic member 24. Here, the interlocking elastic member 24 is, for example, a spring and is disposed between the other end of the actuator 122a (the end close to the locking mechanism 20) and the connecting member 23.

[0042] When the locking mechanism 20 is in the locked state as shown in FIG. 4 and the unlocking mechanism 30 is not performing an unlocking operation as shown in FIG. 3, the right end of the actuator 122a abuts against the return elastic member 122c and enters into the position limiting member 22, abuts against the interlocking elastic member 24, further deforms the interlocking elastic member 24, and pushes a part of the connecting member 23 into the second pipe member 124. In other words, when the locking mechanism 20 is in the locked state, the first pipe member 122 is clamped to the position limiting member 22 via the actuator 122a, and the connecting member 23 is clamped to the second pipe member, whereby the first pipe member 122 and the second pipe member 124 are fixed to the locking mechanism 20 and cannot rotate freely, ensuring that the baby bed 1 is maintained in the deployed state.

[0043] When the user attempts to unlock and fold up the baby bed 1 for storage, the operating member 32 can be pushed into the accommodation hole A. At this time, the positioning member 34 slides to the center of the operating member 32 under the common position limitation of the position limiting portion 31a and the chute S. In this embodiment, since the extending direction of the chute S is inclined with respect to the extending direction of the first lateral portion 110, when the positioning member 34 slides to the center of the operating member 32, the driving member 33 is pulled and the actuator 122a is slid to the positioning portion 122b to disengage from the position limiting member 22. At the same time, since the interlocking elastic member 24 is no longer abutted against the actuator 122a, the connecting member 23 enters the inside of the lock case 21 and is no longer clamped by the second pipe member 124, and the unlocked state as shown in FIGS. 5 and 6 is achieved. In other words, the connecting member 23 is selectively clamped to the second pipe member 124 by the abutment of the interlocking elastic member 24. Thereafter, the user can rotate the first pipe member 122 and the second pipe member 124 counterclockwise and clockwise in FIG. 7 respectively to start the folding storage of the baby bed 1.

[0044] On the one hand, as shown in FIG. 8, the third pivoting portion 240 includes an auxiliary upright portion 242 and a pivoting position limiting portion 244. Here, the auxiliary upright portion 242 can assist the upright portion 232 at the central portion of the baby bed 1 to support the frame body 10, and the pivoting position limiting portion 244 is, for example, a bump, which is arranged at one end of one of the third pipe member 222 or the fourth pipe member 224 and is used to limit the third pipe member 222 and the fourth pipe member 224 in one direction. In other words, when the third pipe member 222 and the fourth pipe member 224 are deployed parallel to the ground, the pivoting position limiting portion 244 clamps with the third pipe member 222 or the fourth pipe member 224, making it impossible for both of them to continue to pivot downward. Conversely, when the user starts to fold and store the baby bed 1, just kicking the third pivoting portion 240 upward by a certain distance with the foot, the third pipe member 222 and the fourth pipe member 224 will not be clamped by the pivoting position limiting portion 244 and will rotate relative to each other with the bottom pipe 250 as the pivot axis to reach the state shown in FIG. 9. Finally, the user can further move the side rods 300 on both sides closer to the middle to completely fold and store the baby bed 1 to reach the state shown in FIG. 10.

[0045] In addition, when the baby bed 1 is deployed from the stored state to the deployed state, the actuator 122a automatically enters the position limiting member 22 under the elastic force of the return elastic member 122c again, abuts against and presses the interlocking elastic member 24, and further pushes the connecting member 23 into the second pipe member 124 to lock it, which is quite simple and convenient.

[0046] In addition to this, in this embodiment, an example is given in which the first pipe member 122 is clamped to the position limiting member 22 via the actuator 122a and clamped to the second pipe member 124 via the connecting member 23, but the present invention is not limited to this. In other possible embodiments, the actuator 122a can also be arranged at one end of the second pipe member 124 and clamped to the first pipe member 122 via the connecting member 23 to form a locked state, and the same effect can be obtained.

[0047] Furthermore, in this embodiment, the first vertical portion 120 and the second vertical portion 220 are assembled using the first pipe member 122, the second pipe member 124, the third pipe member 222, and the fourth pipe member 224, and a part of the locking assembly and the unlocking assembly are drilled in the hollow portions of the above-mentioned pipe members. However, the present invention is not limited to this. In other possible embodiments, all of the above-mentioned pipe members can be replaced using solid rods. At the same time, a chute or a receiving groove that can slide or expand and contract the above-mentioned assembly can be provided in the rod member, and the same effect can be obtained.

[0048] Referring to FIG. 11, FIG. 11 is a partially enlarged schematic view of the upper frame of the second embodiment of the baby bed of the present invention. The baby bed 1 of this embodiment is similar to the baby bed 1 shown in FIG. 1. The difference is that the unlocking mechanism 30' in FIG. 11 further includes a protection member 35, and the protection member 35 is drilled in the unlocking case 31'.

[0049] Specifically, in the unlocking mechanism 30' of this embodiment, in order to prevent the user from accidentally contacting the operating member 32 and accidentally folding the baby bed 1 and causing injury to the infant, a protection mechanism is newly provided so that the user does not accidentally contact the operating member 32. Referring to FIGS. 12 and 13, where FIG. 12 is a schematic exploded view of the components in FIG. 11, and FIG. 13 is a schematic view of a partial configuration of the components in FIG. 11. In this embodiment, an operation hole H is formed in the pipe body 112' of the first lateral portion 110'. Further, the unlocking mechanism 30' further includes a protection elastic member 36. In addition to the structures in FIGS. 3 and 5, a support portion 31b and an opening O are formed in the unlocking case 31'. Here, the support portion 31b is recessed toward the inside of the unlocking case 31'. The protection member 35 is drilled in the operation hole H, and a part of it is exposed through the opening O so that the user can operate it. The protection elastic member 36 is, for example, a linear spring and is disposed between the protection member 35 and the support portion 31b.

[0050] As shown in Fig. 13, the protection member 35 includes a stopper portion 35a having a shape corresponding to the upper edge of the operation member 32. When the locking mechanism 20 is in the locked state, since the upper edge of the operation member 32 and the stopper portion 35a are in contact with each other, the user cannot directly push the operation member 32 into the accommodation hole A, and the baby bed 1 cannot be folded and stored. Thereby, it is ensured that the baby bed 1 is not accidentally folded due to the user's accidental contact with the operation member 32.

[0051] Referring to Figs. 14 and 15, here, Fig. 14 is a schematic cross-sectional view of the unlocking mechanism of Fig. 11 in the unlocked state, and Fig. 15 is a schematic cross-sectional view of the unlocking mechanism of Fig. 11 in the unlocked state. When the user attempts to fold and store the baby bed 1, it is only necessary to pull the operation member 35 to the left in Fig. 14 with one hand, thereby sliding the stopper portion 35a to the left so that it does not contact the upper edge of the operation member 32. At this time, the user can use other fingers to push the operation member 32 into the accommodation hole A and perform the above-mentioned unlocking and folding storage processes. When the user releases the hand from the unlocking mechanism 30', the protection member 35 is pulled to the right in Fig. 14 by the elastic force of the protection elastic member 36 and contacts the upper edge of the operation member 32 again. In other words, the operation member 32 can selectively contact the stopper portion 35a by the protection elastic member 36, thereby avoiding the user accidentally contacting the operation member 32 and accidentally folding the baby bed 1.

[0052] Referring to Figs. 16 and 17, here, Fig. 16 is a partially enlarged schematic view of the upper frame of the third embodiment of the baby bed of the present invention, and Fig. 17 is a schematic cross-sectional view of Fig. 16. The baby bed 1 of this embodiment is similar to the baby bed 1 shown in Fig. 11. The difference is that the operation member 32 and the protection member 35" of this embodiment are respectively arranged on both opposite sides of the unlocking case 31".

[0053] Specifically, a positioning groove 112b is formed on the inner side of the tube wall of the tube body 112”. In this embodiment, the number of the positioning grooves 112b is, for example, two, and they are arranged at intervals in the extending direction of the first lateral portion 110”. On the other hand, the support portion 31b” is, for example, a lever, and both ends are fitted into the positioning grooves 112b. In other words, the support portion 31b” extends in the extending direction of the first lateral portion 110” and is fixed to the tube body 112”. The protective elastic member 36 is externally fitted to the support portion 31b”, and the protective member 35” is fixed to the protective elastic member 36. Thereby, the protective member 35” can be guided and positioned via the support portion 31b”. The operating member 32 and the protective member 35” can be respectively arranged on both opposite sides of the unlocking case 31”, which is more ergonomic for manual operation.

[0054] Referring to FIG. 18, FIG. 18 is a schematic exploded view of a partial assembly of a fourth embodiment of the baby bed of the present invention. The baby bed 1” of this embodiment is similar to the baby bed 1 shown in FIG. 1. The difference is that the baby bed 1” in FIG. 18 further includes a lower frame locking mechanism 50. Here, the number of the lower frame locking mechanisms 50 is two, and they are respectively arranged between the third pipe member 222 and the fourth pipe member 224 on both sides of the baby bed 1”.

[0055] Specifically, compared with the third pivoting portion 240 of the baby bed 1 position - limiting the third pipe member 222 and the fourth pipe member 224 in one direction via the pivoting position - limiting portion 244, the lower - frame locking mechanism 50 of this embodiment has a precise locking and unlocking function, whereby the third pipe member 222 and the fourth pipe member 224 are fixed in the deployed state or switched between the deployed state and the stored state. Referring to FIGS. 19 and 20, where FIG. 19 is a partially enlarged schematic view of FIG. 18 and FIG. 20 is a cross - sectional schematic view of the lower - frame locking mechanism of FIG. 18 in the locked state. As shown, the lower - frame locking mechanism 50 includes a third pivoting portion 240", a locking member 51, a lower - frame operating member 52, and a lower - frame elastic member 53. Here, the third pivoting portion 240" is provided at one end of the third pipe member 222 and includes a third pipe - member case 246 fixed to the third pipe member 222, and is provided at one end of the fourth pipe member 224 and includes a fourth pipe - member case 248 fixed to the fourth pipe member 224. The third pipe - member case 246 and the fourth pipe - member case 248 together define a pivoting cavity C. The locking member 51 is slidably provided within the pivoting cavity C. The lower - frame operating member 52 is, for example, a support leg that assists in keeping the baby bed 1" standing upright, is connected to the locking member 51, and the lower - frame elastic member 53 is, for example, a spring and is disposed between the locking member 51 and the bottom pipe 250".

[0056] Specifically, the lower frame locking mechanism 50 selectively engages with either or both of the third pipe member case 246 and the fourth pipe member case 248 via the locking member 51 to obtain the effect of locking or unlocking. As shown in FIGS. 19 and 20, the third pipe member case 246 and the fourth pipe member case 248 each have a round lid shape at their respective ends, and engaging features 246a and 248a are formed on the inner surfaces defining the pivoting cavity C. Here, the engaging features 246a and 248a are, for example, bumps corresponding to the circumferential positions of the pivoting cavity C. On the other hand, the locking member 51 includes an engaging portion 51a and an extending portion 51b. Here, the engaging portion 51a is a gear and has a shape corresponding to the engaging features 246a and 248a, and the extending portion 51b is cylindrical, connected to the engaging portion 51a, and the lower frame operating member 52 is fixed to the extending portion 51b. Thus, when the third pipe member 222 and the fourth pipe member 224 are in the deployed state, since the engaging portion 51a receives the abutment of the lower frame elastic member 53 and simultaneously engages with the engaging features 246a and 248a, the third pipe member case 246 relatively fixed to the third pipe member 222 and the fourth pipe member case 248 relatively fixed to the fourth pipe member 224 cannot rotate relative to each other, locking the third pipe member 222 and the fourth pipe member 224 in the deployed state.

[0057] Referring to FIG. 22, FIG. 22 is a schematic cross-sectional view of the unlocking state of the lower frame locking mechanism of FIG. 18. When the user attempts to unlock the third pipe member 222 and the fourth pipe member 224, the user only needs to kick the lower frame operating member 52 a certain distance in the horizontal direction D of FIG. 20 with the foot. At this time, the locking member 51 is moved to the position shown in FIG. 22 by the lower frame operating member 52. Thereby, the engaging portion 51a moves to the right side of the pivot cavity C without clamping with the engaging feature 246a, making the third pipe member case 246 and the fourth pipe member case 248 rotatable relative to each other, and at the same time, the third pipe member 222 and the fourth pipe member 224 can be unlocked. At this time, the user only needs to kick the third pivot portion 240” upward a certain distance to fold the lower frame 200” of the baby bed 1” from the unfolded state to the stored state so as to store the baby bed 1. When the user unfolds the third pipe member 222 and the fourth pipe member 224 again, the engaging features 246a and 248a rotate relative to each other until they are aligned, and the engaging portion 51a is reset again by the elastic force of the lower frame elastic member 53 and engages with the engaging features 246a and 248a simultaneously. In other words, the lower frame locking mechanism 50 engages with at least one of the engaging features 246a and 248a through the engaging portion 51a, and further achieves the effects of locking and unlocking the third pipe member 222 and the fourth pipe member 224, and can improve the stability and convenience during the use of the baby bed 1”.

[0058] In addition, so that the user can simultaneously unlock the lower frame locking mechanisms 50 on both sides, the baby bed 1” of this embodiment further includes a lower frame synchronization mechanism 60, and the lower frame synchronization mechanism 60 is connected between these lower frame locking mechanisms 50.

[0059] Referring to FIGS. 19 to 23, where FIG. 21 is a schematic plan view of the lower frame synchronization mechanism in the locked state of FIG. 18, and FIG. 23 is a schematic plan view of the lower frame synchronization mechanism in the unlocked state of FIG. 18. Specifically, the lower frame synchronization mechanism 60 includes a synchronization member 61 having a disk shape or a spherical shape, and link members 62 having a rod shape corresponding to the number of the lower frame locking mechanisms 50. The synchronization member 61 is pivotally connected to one end of these link members 62, and the other ends of these link members 62 are respectively fixed to the locking members 51 of the lower frame locking mechanisms 50 on both sides.

[0060] Specifically, in this embodiment, the synchronization member 61 is disposed within the bottom tube 250”, and is pivotally fixed to the center of the bottom tube 250” by a fixing member such as a screw or a rivet drilled into the central locking hole of the synchronization member 61. On the other hand, at least a part of these link members 62 is disposed within the bottom tube 250”, and the lower frame operating member 52 is externally fitted onto the bottom tube 250”. Further, as shown in FIG. 19, the lower frame synchronization mechanism 60 further includes a plurality of synchronization locking members 54. Here, the synchronization locking members 54 are, for example, rivets, and the bottom tube 250” is formed with a plurality of synchronization position limiting grooves T having a length corresponding to the number of the locking members 51 and the moving length of the lower frame operating member 52 in the lateral direction D. These synchronization locking members 54 are drilled through the groove holes provided in the extending portions 51b of the corresponding locking members 51, the lower frame operating member 52, the link members 62, and the synchronization position limiting grooves T. In other words, the locking members 51 and the link members 62 are relatively fixed in the lateral direction D, but are relatively rotatable in the circumferential direction of the extending portions 51b. The locking members 51, the lower frame operating member 52, and the link members 62 are slidable in the lateral direction D by the length of the synchronization position limiting grooves T.

[0061] When the user unlocks the lower frame lock mechanism 50 on one side as described above, the lower frame operation member 52 drives the interlocking member 62 and they both move in the lateral direction D, that is, towards the center of the bottom tube 250". Since the synchronization member 61 is pivotally fixed to the center of the bottom tube 250", the synchronization member 61 also rotates by the interlocking member 62 on one side. As a result, the interlocking member 62 on the other side is moved towards the center of the bottom tube 250" in the direction opposite to the lateral direction D and rotated from the position in Fig. 21 to the position in Fig. 23, simultaneously unlocking the lower frame operation member 52 and the lock member 51 on the other side. In other words, due to the interlocking relationship among the lock member 51, the lower frame operation member 52, the synchronization member 61, and the interlocking member 62, the user only needs to unlock the lower frame lock mechanism 50 on one side, and the lower frame synchronization mechanism 60 will simultaneously unlock all the lower frame lock mechanisms 50. This saves the process of the user moving to each position of the baby bed 1" to unlock it, greatly improving the operational convenience.

[0062] Referring to FIGS. 19, 24 and 25, where FIG. 24 is a front schematic view of the lower frame locking mechanism of the baby bed in the deployed state of FIG. 18, and FIG. 25 is a front schematic view of the lower frame locking mechanism of the baby bed in the stored state of FIG. 18. As shown, the lower frame locking mechanism 50 of this embodiment preferably further includes a pivot position limiting member 55, where the pivot position limiting member 55 may be a plug having a cover, and a convex portion 55a is formed inside the cover. On the other hand, a pivot position limiting groove R is formed in one of the third pipe member case 246 and the fourth pipe member case 248. When the assembly of the assemblies is completed, the plug portion of the pivot position limiting member 55 is drilled into the third pipe member case 246, the fourth pipe member case 248 and the locking member 51, the cover portion closes one end of the pivot cavity C, and the convex portion 55a is fitted into the pivot position limiting groove R. With such a configuration, when the third pipe member 222 and the fourth pipe member 224 switch between the deployed state and the stored state as shown in FIGS. 24 and 25, the pivot position limiting member 55 not only flattens the appearance of the third pivot portion 240”, but also can rotate synchronously with the locking member 51. In addition, by fitting the convex portion 55a into the pivot position limiting groove R, the rotation strokes of the locking member 51 and the pivot position limiting member 55 are limited to both ends of the pivot position limiting groove R, and the frame operating member 52 can be rotated to an appropriate position without hindering the storage of the third pipe member 222 and the fourth pipe member 224 while the baby bed 1” is between the deployed and stored states.

[0063] Referring to FIGS. 26 to 29, where FIG. 26 is a partially enlarged schematic view of the fifth embodiment of the baby bed of the present invention, FIG. 27 is an exploded schematic view of the assembly of FIG. 26, FIG. 28 is a perspective schematic view of the lower frame operating member of FIG. 27, and FIG. 29 is a perspective schematic view of the fourth pipe member case and the interlocking member of FIG. 27 from another angle. The baby bed 1” of this embodiment is similar to the baby bed 1” shown in FIG. 18, and the difference is that the baby bed 1” of this embodiment achieves the effect of locking and unlocking directly through the lower frame operating member 52'''.

[0064] Specifically, the lower frame locking mechanism 50''' of this embodiment includes a third pivoting portion 240''' and a lower frame operating member 52'''. The third pivoting portion 240''' includes a third pipe member case 246''' and a fourth pipe member case 248'''. The third pipe member case 246''' is fixed to the third pipe member 222, and the fourth pipe member case 248''' is fixed to the fourth pipe member 224. The third pipe member case 246''' and the fourth pipe member case 248''' together define a pivoting cavity C, and at least one of the third pipe member case 246''' and the fourth pipe member case 248''' forms an engaging feature within the pivoting cavity C. In this embodiment, an engaging feature 248a is formed on the fourth pipe member case 248''', and the engaging feature 248a is, for example, a long groove. On the other hand, the lower frame operating member 52''' is rotatably connected to the third pivoting portion 240''', and a part of it is exposed with respect to the third pivoting portion 240'''. Here, the lower frame operating member 52''' includes an engaging portion 52a. In this embodiment, the engaging portion 52a is, for example, a lug corresponding to the size of the engaging feature 248a, and the engaging portion 52a is selectively clamped to the engaging feature 248a.

[0065] Furthermore, the fourth tube member case 248''' further forms a pivot groove 248b in the pivot cavity C, where the engagement feature 248a, i.e., the long groove, extends along the radial direction of the fourth tube member case 248''', the pivot groove 248b is configured along the circumferential direction of the fourth tube member case 248''', communicates with the long groove 248a, and the engaging portion 52a is slidably provided in the long groove 248a and the pivot groove 248b. Also, the lower frame locking mechanism 50''' further includes a lower frame elastic member 53, and the lower frame elastic member 53 is disposed between the lower frame operating member 52''' and the third pivoting portion 240''' along the extending direction of the engagement feature 248a. Referring to FIGS. 30 and 31, where FIG. 30 shows a schematic view of a right cross-sectional view in the deployed state of the third pivoting portion and the lower frame operating member of the baby bed in FIG. 26, and FIG. 31 shows a schematic view of a right cross-sectional view in the unlocked state of the third pivoting portion and the lower frame operating member of the baby bed in FIG. 26. As shown in the figures, when the baby bed 1” is in the deployed state, the lower frame operating member 52''' is pressed against the lower frame elastic member 53 such that the engaging portion 52a is clamped by the engagement feature 248a. Thus, the third tube member case 246''' and the fourth tube member case 248''' cannot pivot relative to each other, thereby locking the lower frame 200'' in the deployed state. When the user wants to fold the baby bed 1'', the user only needs to kick up the lower frame operating member 52''' upward by a distance along the extending direction of the engagement feature 248a. At this time, the engaging portion 52a moves from the engagement feature 248a to the pivot groove 248b and can slide circumferentially relative to the fourth tube member case 248''' along the pivot groove 248b. Thereby, the third tube member case 246''' and the fourth tube member case 248''' are unlocked and can pivot freely relative to each other.

[0066] In addition to this, the baby bed 1'' of this embodiment also has a function of synchronizing the unlocking of a plurality of lower frame locking mechanisms 50'''. As shown in FIG. 27, the baby bed 1'' further includes a plurality of lower frame synchronization mechanisms 60'''. In this embodiment, the number of the second longitudinal direction portions 220 and the lower frame synchronization mechanisms 60''' is, for example, two. Each lower frame synchronization mechanism 60''' corresponds to each lower frame locking mechanism 50''' and includes an interlocking member 62'''. Here, the interlocking member 62''' is configured to be pivotable within the pivot cavity C and is clamped to the lower frame operating member 52'''. Specifically, a clamping portion 52c is formed on the lower frame operating member 52'''. Here, the clamping portion 52c is, for example, a hole. A convex column 62a is formed on the interlocking member 62''', and the convex column 62a is clamped to the clamping portion 52c. On the other hand, the lower frame 200” further includes a bottom tube 250'''. This bottom tube 250''' is connected to the third pivot portion 240''' of these lower frame locking mechanisms 50''' and is fixed relative to the interlocking member 62 of these lower frame synchronization mechanisms 60'''. Thereby, when the user kicks up the lower frame operating member 52''' upward by a certain distance along the extending direction of the engagement feature 248a as described above, the interlocking member 62''' pivots with respect to the fourth tube member case 248''' due to the operation of the lower frame operating member 52'''. Further, the bottom tube 250''' connected to the other third pivot portion 240''' is synchronously pivoted, and the other third pivot portion 240''' has the same movement mode, achieving the effect of synchronous unlocking.

[0067] Referring to FIGS. 32 to 36, FIG. 32 is a perspective schematic view of a sixth embodiment of the baby bed of the present invention, FIG. 33 is a cross-sectional schematic view of the baby bed of FIG. 32, FIG. 34 is a schematic view of the disassembled parts of the baby bed of FIG. 32, FIG. 35 is a front cross-sectional schematic view of the baby bed of FIG. 32 in a locked state, and FIG. 36 is a front cross-sectional schematic view of the baby bed of FIG. 32 in an unlocked state. The baby bed 1''' of this embodiment is similar to the baby bed 1'' of the fifth embodiment. The difference is that the lower frame locking mechanism 50'''' of this embodiment includes a third pivoting portion 240'''' and a lower frame operating portion. Here, the lower frame operating portion includes a plurality of lower frame operating members 52''''. By operating any of these lower frame operating members 52'''', the user can unlock the baby bed 1''''.

[0068] Specifically, the lower frame operating portion includes a clamp member 51', a pivoting member 55', and a plurality of lower frame operating members 52''''. Here, the clamp member 51' is slidably provided in the pivoting cavity C and is selectively clamped to the engagement feature 248a. The pivoting member 55' is pivotally connected to the clamp member 51'. These lower frame operating members 52'''' are coupled to the pivoting member 55' and are at least partially exposed with respect to the third pivoting portion 240''.

[0069] As shown in FIG. 33, the pivoting member 55' of this embodiment is, for example, a tubular member bored in the bottom tube 250'', and the end of the pivoting member 55' is configured within the pivoting cavity C and clamped with the clamping member 51'. On the other hand, the lower frame operating portion further includes a plurality of interlocking members 62'''' externally fitted on the bottom tube 250'' and relatively fixed to the pivoting member 55'. Here, the number of the lower frame operating members 52'''' corresponds to the number of the interlocking members 62'''', and these lower frame operating members 52'''' are respectively arranged on the corresponding interlocking members 62''''' . Thereby, when the user pulls and lifts any one of the lower frame operating members 52'''', the lower frame operating member 52'''' pivots the pivoting member 55' by the interlocking member 62''''' , and further, the clamping member 51' clamped with the pivoting member 55' is slid in the extending direction of the engaging feature 248a to unclamp it from the engaging feature 248a, and it can be switched from the locked state of FIG. 35 to the unlocked state of FIG. 36. When the user stops pulling up the lower frame operating member 52'''', the clamping member 51' is driven by the elasticity of the lower frame elastic member 53 to return the pivoting member 55' to the locked position by the clamping member 51'.

[0070] In this embodiment, the interlocking member 62'''' is externally fitted outside the bottom tube 250''. However, the present invention is not limited to this. In other possible embodiments, the interlocking member 62'''' may also be completely covered inside the bottom tube 250'', and the bottom tube member 250'' is exposed from the lower frame operating member 52'''' for operation by the user.

[0071] Compared with the prior art, the baby bed 1 of the present invention includes a locking mechanism 20 and an unlocking mechanism 30, and can lock the housing 10 in the deployed state or release the above-mentioned locked state. Further, due to the pivoting relationship between the components of the housing 10, the user can unlock and fold it with only one hand at a time, and there is no need to disassemble each component one by one, which can greatly save the time required for storing the baby bed 1 and improve the convenience in use.

[0072] The present invention has been described above in connection with the best mode for carrying it out. However, the present invention is not limited to the above-described embodiments, and various modifications and equivalent combinations based on the essence of the present invention must be covered.
