Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a bed frame and a children's bed. Background Technology

[0002] Children's beds are primarily used to provide a place for children to rest or play. Typically, to facilitate storage and transportation, they are designed with a foldable structure to reduce their size. A typical children's bed consists of uprights and multiple foldable armrests connected between the uprights. These armrests are pivotally connected, and by pivoting, they bring the uprights closer together, allowing the bed to fold. However, due to structural limitations, the surface of the armrests in commonly used bedspreads is often uneven after pivoting. This can easily cause the bed linens laid on the armrests to not lie flat and look untidy.

[0003] In addition, to facilitate the rest of younger infants, most children's beds on the market now come with a hammock. To ensure the mattress in the hammock remains flat and for the infant's comfort, the hammock typically has a support structure to support the mattress, which can be folded up with the children's bed. However, the support structure of most children's beds on the market still has a considerable volume when folded, making it inconvenient for storage and transportation. Utility Model Content

[0152] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0153] Figures 1 to 4 A schematic diagram of a children's bed 1000 according to an embodiment of the present invention is shown. The children's bed 1000 is mainly used to provide a place for children or infants to rest or play. Specifically, the children's bed 1000 has a generally rectangular frame structure, including a bed frame 10 (see...). Figure 5 , Figure 13 or Figure 17 ) and the children's bed cover 1200 (e.g., a cloth cover, etc., placed outside the bed frame 10) Figures 1 to 4 The bed frame 10 is foldable, allowing the children's bed 1000 to be folded and switched between an unfolded and folded state. When folded, the children's bed 1000 has a small volume, making it easy to store and transport.

[0154] Figure 5 A perspective view of a bed frame 10 according to a first embodiment of the present invention is shown. The bed frame 10 includes a first upright 111, a second upright 112, and an armrest tube mechanism 120. The second upright 112 is disposed opposite to the first upright 111. The armrest tube mechanism 120 is movably connected between the first upright 111 and the second upright 112. The armrest tube mechanism 120 in its unfolded position (see...) Figure 5 and Figure 6 ) and closing position (see Figure 8 It can be switched between the two positions. When the handrail tube mechanism 120 is in the extended position, the handrail tube mechanism 120 is at least partially parallel to the horizontal plane.

[0155] The aforementioned bed frame 10, by movably connecting the armrest tube mechanism 120 between the first upright 111 and the second upright 112, allows the armrest tube mechanism 120 to have an unfolded position and a folded position. When the armrest tube mechanism 120 is in the folded position, the entire bed frame 10 is in a folded state, making the bed frame 10 smaller in size for easier storage and transportation. Since the armrest tube mechanism 120 is at least partially parallel to the horizontal plane when it is in the unfolded position, the children's bed cover 1200 (e.g., a cloth cover) installed on the armrest tube mechanism 120 tends to be flat when the armrest tube mechanism 120 is in the unfolded position, resulting in a better fit with the armrest tube mechanism 120 and thus a neater appearance for the bed frame 10 covered with the children's bed cover 1200.

[0156] In some embodiments, multiple first columns 111 and multiple second columns 112 are provided, with the multiple first columns 111 and multiple second columns 112 alternately arranged in the circumferential direction, and a handrail tube mechanism 120 is provided between adjacent first columns 111 and second columns 112. Thus, when all handrail tube mechanisms 120 are in the extended position, each first column 111, each handrail tube mechanism 120, and each second column 112 is sequentially connected to form a ring structure. It should be understood that "multiple" as used in this utility model refers to at least two.

[0157] Specifically, see Figure 5 The bed frame has two first uprights 111 and two second uprights 112, and four armrest tube mechanisms 120. When all armrest tube mechanisms 120 are in the extended position, each first upright 111 and each second upright 112 is connected by the armrest tube mechanism 120 to form a rectangular bed frame 10. See also... Figures 5 to 8In some embodiments, the handrail tube mechanism 120 includes a first handrail tube assembly 121, which includes a first handrail tube 122. The first handrail tube 122 has a first pivot end 1221A and a first sliding end 1221B. The first pivot end 1221A is pivotally connected to either the first column 111 or the second column 112, and the first sliding end 1221B is pivotally connected to and slidably connected to either the second column 112 or the first column 111. In other words, when the first pivot end 1221A is pivotally connected to one of the first column 111 and the second column 112, the first sliding end 1221B is pivotally connected to and slidably connected to the other. When the handrail tube mechanism 120 is in the extended position, the first column 111 and the second column 112 are separated from each other (see...). Figure 5 and Figure 6 ), and the corresponding first handrail tube 122 is at least partially parallel to the horizontal plane.

[0158] See Figure 6 and Figure 7 In some embodiments, the first armrest tube 122 includes a first tube segment 1222 and a second tube segment 1223 that are connected to each other and arranged at an angle. The first end of the first tube segment 1222 away from the second tube segment 1223 is a first pivot end 1221A, and the first end of the second tube segment 1223 away from the first tube segment 1222 is a first sliding end 1221B. Positioning the first pivot end 1221A and the first sliding end 1221B at the ends of each tube segment facilitates the connection between the first armrest tube 122 and the first upright 111 and the second upright 112. Simultaneously, when the armrest tube mechanism 120 is in the unfolded position, the first armrest tube 122 has its maximum unfolded length, maximizing the distance between the first upright 111 and the second upright 112. This results in the bed frame 10 having a larger accommodating space to support the children's bed cover 1200 when unfolded, increasing the area of ​​the children's bed cover 1200 in the unfolded position, and providing a larger space for children to rest or play. More specifically, see Figure 6 and Figure 7 When the handrail tube mechanism 120 is in the unfolded position, the first tube segment 1222 is parallel to the horizontal plane, and the second tube segment 1223 extends downward from the second end of the first tube segment 1222.

[0159] In some embodiments, the included angle α between the first pipe segment 1222 and the second pipe segment 1223 is greater than 90°.

[0160] More specifically, in some embodiments, the included angle α between the first pipe segment 1222 and the second pipe segment 1223 is 150°. Of course, in some alternative embodiments, the included angle α between the first pipe segment 1222 and the second pipe segment 1223 can also be 100°, 120° or 140°, etc., and no specific limitation is made here.

[0161] To improve the ease of connecting the first handrail tube 122 to the first upright 111 and the second upright 112, and to improve the ease of switching the first handrail tube 122 between the extended and retracted positions, see [reference needed]. Figure 6 and Figure 8 In some embodiments, the bed frame 10 further includes a apex corner 130. More specifically, in some embodiments, the first upright 111 or the second upright 112 is provided with a apex corner 130, and the apex corner 130 has a first pivot portion Q1, which is used to pivot with a first pivot end 1221A.

[0162] Furthermore, in some embodiments, the bed frame 10 also includes a slider 140. The slider 140 is slidably mounted on either the first upright 111 or the second upright 112. Each slider 140 has a second pivot portion Q2, which is used for pivotal connection with the first sliding end 1221B. When the apex 130 connected to a certain first armrest tube 122 is located on either the first upright 111 or the second upright 112, the slider 140 connected to that first armrest tube 122 is located on the other. When the user needs to switch the bed frame 10 from an unfolded state to a folded state, that is, when the armrest tube mechanism 120 is switched from an unfolded position to a folded position (from... Figure 6 The status shown has switched to Figure 8 In the indicated state, the user pushes or pulls the slider 140, causing the slider 140 to move the first sliding end 1221B of the first armrest tube 122 downwards (in the F1 direction) along the corresponding first column 111 or second column 112. This allows the first sliding end 1221B of the first armrest tube 122 to rotate at the second pivot Q2 of the slider 140, and simultaneously causes the first pivot end 1221A of the first armrest tube 122 to rotate at the first pivot Q1 of the apex 130, thereby causing the first column 111 and the second column 112 to move closer together. When the user needs to switch the bed frame 10 from the folded state to the unfolded state, that is, when the armrest tube mechanism 120 is switched from the folded position to the unfolded position (from... Figure 8 The status shown has switched to Figure 6 In the state shown, push the slider 140 to cause the slider 140 to drive the first sliding end 1221B of the first handrail tube 122 to move upward (in the F2 direction) along the corresponding first column 111 or second column 112. This will cause the first sliding end 1221B of the first handrail tube 122 to rotate at the second pivot part Q2 of the slider 140, and at the same time cause the first pivot end 1221A of the first handrail tube 122 to rotate at the first pivot part Q1 of the apex 130, thereby causing the first column 111 and the second column 112 to move away from each other.

[0163] More specifically, in some embodiments, such as Figure 5 and Figure 6As shown, in the annular bed frame 10 formed by connecting multiple first uprights 111, multiple second uprights 112, and multiple first handrail tube assemblies 121, each apex 130 on the first uprights 111 or second uprights 112 includes a first apex portion 131 and a second apex portion 132, which are connected to each other and arranged at an angle. Both the first apex portion 131 and the second apex portion 132 are provided with a first pivot portion Q1, which is used to pivotally connect with the first pivot end 1221A of the first handrail tube 122. Similarly, each sliding member 140 on the second uprights 112 or the first uprights 111 may also include a first sliding portion 141 and a second sliding portion 142, which are connected to each other and arranged at an angle. Both the first sliding part 141 and the second sliding part 142 are provided with a second pivot part Q2, which is used to pivotally connect with the first sliding end 1221B of the first handrail tube 122. Thus, when the sliding member 140 slides on the second column 112 or the first column 111, the first sliding ends 1221B of the two first handrail tubes 122 connected to the same sliding member 140 will slide up and down with the sliding member 140 and pivot relative to the sliding member 140. Simultaneously, the first pivot ends 1221A of the two first handrail tubes 122 connected to the same apex 130 will pivot relative to the apex 130.

[0164] See Figures 5 to 8 In this embodiment, the first handrail tube assembly 121 includes two first handrail tubes 122. The first pivot end 1221A of one first handrail tube 122 is pivotally connected to the first column 111, and the first sliding end 1221B of the other first handrail tube 122 is pivotally connected to and slidably connected to the second column 112. The first pivot end 1221A of the other first handrail tube 122 is pivotally connected to the second column 112, and the first sliding end 1221B of the other first handrail tube 122 is slidably pivotally connected to the first column 111. In other words, when the first handrail tube assembly 121 includes two first handrail tubes 122, the first pivot end 1221A of one of the first handrail tubes 122 is pivotally connected to the first column 111, while the first sliding end 1221B of the first handrail tube 122 is pivotally connected to and slidably connected to the second column 112; and the first pivot end 1221A of the other first handrail tube 122 is pivotally connected to the second column 112, while the first sliding end 1221B of the first handrail tube 122 is slidably pivotally connected to the first column 111. More specifically, when the handrail tube mechanism 120 is in the unfolded position, the two first handrail tubes 122 in the first handrail tube assembly 121 are arranged side by side in the horizontal direction, and the projections of the first tube segments 1222 of the two first handrail tubes 122 on a vertical plane parallel to the LR direction (left-right direction) and perpendicular to the horizontal plane at least partially overlap (see...). Figure 7 ).

[0165] The following is combined Figure 5 and Figure 7 To explain the meaning of the above-mentioned "two first handrail tubes 122 are arranged side by side in the horizontal direction, and the projections of the first pipe segments 1222 of the two first handrail tubes 122 on the vertical plane that is parallel to the LR direction (left and right direction) and perpendicular to the horizontal plane at least partially overlap".

[0166] Figure 5 The diagram schematically illustrates a bed frame 10 comprising two first uprights 111, two second uprights 112, and a handrail tube mechanism 120, as shown in this embodiment. When unfolded, the bed frame 10 is generally square in shape and is generally symmetrical both horizontally and vertically. See also... Figure 5 and Figure 7 Taking one of the first pillars 111 and 112 arranged along the left-right direction as an example, when the two first handrail tubes 122 between them are in the unfolded position, the first segments 1222 of the two first handrail tubes 122 are arranged side by side in the horizontal direction (specifically, in the front-back direction), and the two first segments 1222 partially overlap in the front-back direction. Alternatively, taking one of the first pillars 111 and 112 arranged along the front-back direction as an example, when the two first handrail tubes 122 between them are in the unfolded position, the first segments 1222 of the two first handrail tubes 122 are arranged side by side in the horizontal direction (specifically, in the left-right direction), and the two first segments 1222 partially overlap in the left-right direction.

[0167] It should be noted that, unless otherwise explicitly specified and limited, the directional terms such as "front," "rear," "left," and "right" for the bed frame 10 in various embodiments of this utility model are based on the "front," "rear," "left," and "right" orientations shown in the illustrations of the bed frame 10. Furthermore, the "front" and "rear" directions are schematically indicated by arrows B and P, and the "left" and "right" directions are schematically indicated by arrows L and R. These directional terms are only used to make the description of the embodiments of this utility model clearer and are not intended to unduly limit the scope of protection of this utility model.

[0168] See Figure 5 and Figure 6 In some embodiments, both the first column 111 and the second column 112 are provided with apex corners 130. Each apex corner 130 includes a first apex corner portion 131 and a second apex corner portion 132, which are connected to each other and arranged at an included angle. Both the first apex corner portion 131 and the second apex corner portion 132 are provided with a first pivot portion Q1, which is used to pivotally connect with the first pivot end 1221A of the first handrail tube 122.

[0169] See also Figure 5 and Figure 6In some embodiments, a sliding member 140 is slidably provided on both the first column 111 and the second column 112. The sliding member 140 can slide up and down on the first column 111 and the second column 112. Each sliding member 140 includes a first sliding part 141 and a second sliding part 142, which are connected to each other and arranged at an included angle. Both the first sliding part 141 and the second sliding part 142 are provided with a second pivot part Q2, which is used to pivotally connect with the first sliding end 1221B of the first handrail tube 122. When each of the first armrest tube assemblies 121 switches from the unfolded position to the folded position, the sliding member 140 located on each of the first uprights 111 and the second uprights 112 moves downward (in the F1 direction) along the corresponding first uprights 111 and second uprights 112. At the same time, the first sliding end 1221B of each of the first armrest tubes 122 pivots relative to the second pivot part Q2 of the sliding member 140, and the first pivot end 1221A of each of the first armrest tubes 122 pivots relative to the first pivot part Q1 of the apex 130. In this way, each of the first uprights 111 and each of the second uprights 112 can move closer to each other, so that the bed frame 10 switches from the unfolded state to the folded state. When each of the first armrest tube assemblies 121 switches from the folded position to the unfolded position, the sliding members 140 located on each of the first uprights 111 and the second uprights 112 move upward (in the F2 direction) along the corresponding first uprights 111 and second uprights 112. At the same time, the first sliding end 1221B of each of the first armrest tubes 122 pivots relative to the second pivot part Q2 of the sliding member 140, and the first pivot end 1221A of each of the first armrest tubes 122 pivots relative to the first pivot part Q1 of the apex 130. In this way, the first uprights 111 and the second uprights 112 can be moved away from each other, so that the bed frame 10 switches from the folded state to the unfolded state.

[0170] See Figure 6 and Figure 9 In some embodiments, the apex 130 is provided with a locking mechanism 150. When the armrest tube mechanism 120 is in the unfolded position, the locking mechanism 150 can lock into the slider 140 to restrict the slider 140 from sliding relative to the column 110, so that the bed frame 10 remains in the unfolded state.

[0171] See also Figure 6 and Figure 9In some embodiments, the locking mechanism 150 includes a locking member 151 pivotally connected to a apex corner 130. Specifically, a support base 133 is provided on the apex corner 130, and the locking member 151 is pivotally connected to the support base 133. The locking member 151 has an operating end 1511 and a locking end 1512, and the sliding member 140 is provided with a locking engagement portion 143. The locking member 151 is pivotable between a locked position and an unlocked position. When the locking member 151 is in the locked position, the locking end 1512 can lock into the locking engagement portion 143. When the locking member 151 is in the unlocked position, the locking end 1512 can disengage from the locking engagement portion 143. More specifically, the pivot point between the locking member 151 and the support base 133 is located between the operating end 1511 and the locking end 1512, so that when the locking member 151 pivots on the support base 133, it has a roughly "seesaw" structure. That is, pressing and rotating the operating end 1511 brings it closer to the center of the first post 111 or the second post 112, so that when the locking member 151 rotates, the locking end 1512 tilts away from the center of the first post 111 or the second post 112. Of course, the locking member 151 can also be configured to pull the operating end 1511 to disengage the locking end 1512 from the locking engagement part 143.

[0172] Further, see Figure 9 In some embodiments, the locking mechanism 150 further includes a reset member 152. The operating end 1511 is operable to pivot the locking member 151 from a locked position to an unlocked position, and the reset member 152 biases the operating end 1511 to pivot the locking member 151 constantly toward the locked position. The reset member 152 is, for example, a spring that abuts against the operating end 1511 and provides a reset force away from the center of the first post 111 or the second post 112. When the user needs to switch the locking member 151 from the locked position to the unlocked position, simply pressing the operating end 1511 causes the locking end 1512 to tilt away from the center of the first post 111 or the second post 112, thereby disengaging the locking end 1512 from the locking engagement portion 143. Under the action of the reset member 152, the user only needs to release the operating end 1511 to switch the locking member 151 from the unlocked position to the locked position.

[0173] Alternatively, in other embodiments, the support base 133 may be omitted, and the locking member 151 may be directly pivotally connected to the apex 130 (see...). Figure 32Specifically, a mounting base 134 is provided on the apex 130, and a pressing channel 1341 is provided within the mounting base 134. The operating end 1511 of the locking member 151 extends into the mounting base 134 and is accommodated within the pressing channel 1341. More specifically, the pressing channel 1341 extends through the mounting base 134 along its length, and a button 153 is movably disposed within the pressing channel 1341. The button 153 is located on the side of the operating end 1511 facing away from the column 110 and abuts against the operating end 1511. In this way, the user can directly push the operating end 1511 to rotate around the pivot point between the locking member 151 and the apex 130 by horizontally pressing the button 153, so that the locking end 1512 is raised to disengage from the locking engagement part 143. Thus, the user only needs to horizontally press the button 153 to rotate the locking member 151 without pressing the rotating operating end 1511, making the operation more convenient and faster.

[0174] Of course, in some alternative embodiments, the implementation of the locking mechanism 150 is not limited to the examples above, as long as it can lock the sliding member 140.

[0175] See Figures 5 to 9 In some embodiments, the first handrail tube assembly 121 further includes a rotating connection mechanism 123. Two first handrail tubes 122 are pivotally connected via the rotating connection mechanism 123. Specifically, when the first handrail tube assembly 121 includes two first handrail tubes 122, the two first handrail tubes 122 are rotatably connected via the rotating connection mechanism 123. When the sliding member 140 corresponding to one of the first handrail tubes 122 moves downward on the first column 111 or the second column 112, the first sliding end 122B of the first handrail tube 122 moves downward, causing the first handrail tube 122 to tilt and have a downward tendency. At this time, the rotating connection mechanism 123 also moves downward under the influence of the first handrail tube 122. Under the action of the rotating connection mechanism 123, the other first handrail tube 122 can also have a downward tendency, thereby enabling the sliding member 140 corresponding to the other first handrail tube 122 to move downward relative to the second column 112 or the first column 111. As can be seen, the rotating connection mechanism 123 has a linkage function, enabling the two first handrail tubes 122 between adjacent first uprights 111 and second uprights 112 to rotate synchronously. By setting the rotating connection mechanism 123, the user can push or pull a single sliding member 140 downwards to retract all the handrail tube mechanisms 120, thereby realizing the folding of the entire children's bed 1000.

[0176] Specifically, the rotating connecting mechanism 123 is connected to the first segment 1222 of the two first armrest tubes 122, and when the two first armrest tubes 122 are in the unfolded position, the two first segment 1222 have overlapping areas. Furthermore, when the armrest tube mechanism 120 is in the unfolded position, that is, when the two first armrest tubes 122 are in the unfolded position, the rotating connecting mechanism 123 is located below each first segment 1222. This avoids the rotating connecting mechanism 123 protruding above the horizontal plane where the first armrest tubes 122 are located, thus preventing problems such as the children's bed sling 1200 not fitting properly.

[0177] It should be noted that "when the handrail tube mechanism 120 is in the unfolded position, the rotating connecting mechanism 123 is located below each of the first tube segments 1222" means that when the handrail tube mechanism 120 is in the unfolded position, along the first connecting portion 12311 (see...) Figure 7 ) and the second connecting part 12312 (see Figure 7 From the perspective of the orientation of the rotating connection mechanism 123, the height of the end of the rotating connection mechanism 123 with the first connecting part 12311 is lower than the height of the upper surface of the first tube segment 1222. In other words, the end of the rotating connection mechanism 123 with the first connecting part 12311 will not protrude from the horizontal plane of the upper surface of the first tube segment 1222, thereby improving the fit of the children's bed cover 1200 on the armrest tube mechanism 120.

[0178] See Figures 6 to 8 In some embodiments, the rotating connection mechanism 123 includes a rotating member 1231. Two rotating members 1231 are provided, and each rotating member 1231 has a first connecting portion 12311 and a second connecting portion 12312. Each first handrail tube 122 is correspondingly connected to the first connecting portion 12311 of each rotating member 1231, and the two second connecting portions 12312 are rotatably connected. When the two first handrail tubes 122 in the first handrail tube group 121 are in the unfolded position, the two rotating members 1231 are stacked on top of each other; when the two first handrail tubes 122 in the first handrail tube group 121 switch from the unfolded position to the folded position, the two rotating members 1231 rotate relative to each other through the second connecting portions 12312 to form a certain included angle. Specifically, when the first column 111 and the second column 112 approach each other, the included angle between the two rotating members 1231 gradually increases.

[0179] Specifically, in some embodiments, such as Figure 10 As shown, the rotating component 1231 includes a first clamping plate 12313, a connecting plate 12314, and a second clamping plate 12315. The connecting plate 12314 is connected between the first clamping plate 12313 and the second clamping plate 12315, and the first clamping plate 12313, the connecting plate 12314, and the second clamping plate 12315 form a retaining groove 12316 (see...). Figure 10The rotating component 1231 is arranged in a generally U-shaped structure. Both the first clamping plate 12313 and the second clamping plate 12315 are provided with a first connecting portion 12311 and a second connecting portion 12312, with the first connecting portion 12311 being closer to the opening of the retaining groove 12316 than the second connecting portion 12312. The first handrail tube 122 is confined within the retaining groove 12316 and connected to the two first connecting portions 12311. More specifically, both the first connecting portion 12311 and the second connecting portion 12312 are limiting holes. By placing the first handrail tube 122 within the retaining groove 12316 and connecting it to the first handrail tube 122 through screws or bolts passing through the limiting holes (first connecting portions 12311), the first handrail tube 122 can be stably mounted on the rotating component 1231. Furthermore, the two rotating components 1231 can be rotatably connected by a rotating shaft or the like passing through the limiting holes (second connecting portions 12312).

[0180] See Figure 10 In some embodiments, the rotating member 1231 further includes reinforcing ribs 12317. Both the first clamping plate 12313 and the second clamping plate 12315 are provided with reinforcing ribs 12317, with the reinforcing ribs 12317 on the first clamping plate 12313 extending toward the second clamping plate 12315, and the reinforcing ribs 12317 on the second clamping plate 12315 extending toward the first clamping plate 12313. By adding reinforcing ribs 12317, the overall structural strength of the rotating member 1231 can be improved. Furthermore, the ends of each reinforcing rib 12317 near the opening of the retaining groove 12316 can be used to support the first handrail tube 122 (see...) which is confined within the retaining groove 12316. Figure 7 ).

[0181] See Figure 11 and Figure 12 In some alternative embodiments, the rotating connection mechanism 123 includes two rotating connection portions 1232, each of which includes a clamping plate 12321 and a connecting post 12322 fixed to the clamping plate 12321. The clamping plate 12321 is provided with a first connecting portion 12311, and the two first handrail tubes 122 are respectively connected to the first connecting portions 12311 of the two rotating connection portions 1232, and are pivotally connected through the connecting posts 12322 of the two rotating connection portions 1232.

[0182] See also Figure 11 and Figure 12The clamping plates 12321 of the two rotating connecting parts 1232 and the connecting posts 12322 of the two rotating connecting parts 1232 enclose a retaining groove 12316. The two first handrail tubes 122 are confined within the retaining groove 12316 and connected to the corresponding first connecting part 12311. Alternatively, one of the two first handrail tubes 122 is located within the retaining groove 12316 and connected to the corresponding first connecting part 12311, while the other is located outside the retaining groove 12316 and connected to the corresponding first connecting part 12311. Still alternatively, both first handrail tubes 122 are located outside the retaining groove 12316 and connected to the corresponding first connecting part 12311.

[0183] See Figure 13 and Figure 14 In some embodiments, the bed frame 10 further includes a first protective component 160. Specifically, the first protective component 160 is disposed on the first armrest tube 122 and located at the pivot joint of the two first armrest tubes 122, that is, at the connection between the first armrest tube 122 and the rotating connection mechanism 123. When the armrest tube mechanism 120 switches from the unfolded position to the retracted position, the two first armrest tubes 122 pivot relative to the rotating connection mechanism 123 respectively, and together with the rotating connection mechanism 123, form a first shearing trap area 127 (see...). Figure 8 The first protective component 160 is used to shield the first shear trap area 127 (see comparison). Figure 8 and Figure 14 In this way, during the folding process of the bed frame 10, not only can the children's bed cover 1200 be prevented from entering the first shearing trap area 127, thus avoiding the impact on the smoothness of folding the bed frame 10, but the user's hands can also be prevented from accidentally entering the first shearing trap area 127, thereby preventing possible pinching injuries.

[0184] In one embodiment, at least one of the two first handrail tubes 122 between the first column 111 and the second column 112 is provided with a first protective component 160. In other words, any one of the first handrail tubes 122 may be provided with the first protective component 160, or both of the first handrail tubes 122 may be provided with the first protective component 160.

[0185] See Figure 14 and Figure 15In some embodiments, the first protective component 160 includes a first protective baffle 161 and a first protective connector 162 connected to each other. The first protective baffle 161 is used to shield the first shearing and clamping area 127. In this embodiment, the first protective baffle 161 is generally trapezoidal in shape, and the first protective connector 162 is disposed at one bottom edge of the first protective baffle 161. In this embodiment, the first protective baffle 161 and the first protective connector 162 are integrally formed. In other embodiments, the first protective baffle 161 and the first protective connector 162 can also be connected by riveting, welding, or other methods. The side of the first protective connector 162 facing away from the first protective connector 162 forms a first arc-shaped concave surface 1621 that can fit against the outer wall of the first handrail tube 122. In this embodiment, two first connecting protrusions are spaced apart on one side of the first arc-shaped concave surface 1621, and each first connecting protrusion is provided with a first connecting hole 1622. In other embodiments, the number of first connecting protrusions and first connecting holes 1622 may be more than two or less than two. The corresponding first handrail tube 122 is provided with two first fixing holes (not shown in the figure) that are respectively opposite to the two first connecting holes 1622. Two fasteners (such as rivets, screws, or pins) pass through the corresponding first connecting holes 1622 and the first fixing holes to connect the first protective component 160 and the first handrail tube 122. In this way, the stability of the first protective component 160 after installation can be improved. Of course, in some alternative embodiments, the first protective component 160 can also be connected to the first handrail tube 122 by snap-fit, or the first protective component 160 can also be integrally formed on the first handrail tube 122.

[0186] Figure 16 A perspective view of a bed frame 10 according to a second embodiment of the present invention is shown. Similar to the first embodiment described above, the bed frame 10 includes a first upright 111, a second upright 112, and an armrest tube mechanism 120. The second upright 112 is disposed opposite to the first upright 111. The armrest tube mechanism 120 is movably connected between the first upright 111 and the second upright 112. The armrest tube mechanism 120 is in the unfolded position (see 16 and 17). Figure 17 ) and closing position (see Figure 19 It can be switched between the two positions. When the handrail tube mechanism 120 is in the extended position, the handrail tube mechanism 120 is at least partially parallel to the horizontal plane.

[0187] Comparing the bed frame 10 of the first embodiment with the bed frame 10 of the second embodiment (see...) Figure 5 and Figure 16 As can be seen, the armrest tube mechanism 120 of the bed frame 10 in the second embodiment is different from the armrest tube mechanism 120 of the bed frame 10 in the first embodiment.

[0188] See Figure 16In some embodiments, the handrail tube mechanism 120 includes a second handrail tube group 124, which includes both a second handrail tube 125 and a third handrail tube 126, and there are two of each of the second handrail tube 125 and the third handrail tube 126. See also Figure 17 Each second handrail tube 125 has a second pivot end 1251A and a second sliding end 1251B. The two second pivot ends 1251A are pivotally connected, and the two second sliding ends 1251B are slidably disposed on the first column 111 and the second column 112, respectively, and pivotally connected to the first column 111 and the second column 112. Each third handrail tube 126 has a third pivot end 1261A and a fourth pivot end 1261B. The two third pivot ends 1261A are pivotally connected, and the two fourth pivot ends 1261B are pivotally connected to the first column 111 and the second column 112, respectively. When the handrail tube mechanism 120 is in the deployed position, at least a portion of each second handrail tube 125 and at least a portion of each third handrail tube 126 are parallel to the horizontal plane. Therefore, when the armrest tube mechanism 120 is in the unfolded position, the child bed cover 1200 (e.g., a cloth cover) installed on the armrest tube mechanism 120 tends to be flat, which makes it fit better with the armrest tube mechanism 120, and thus makes the bed frame 10 covered with the child bed cover 120 look neater.

[0189] See Figure 18 In some embodiments, the second handrail tube 125 includes a third tube segment 1252 and a fourth tube segment 1253 connected and arranged at an angle. The first end of the third tube segment 1252 away from the fourth tube segment 1253 is a second pivot end 1251A, and the first end of the fourth tube segment 1253 away from the third tube segment 1252 is a second sliding end 1251B. Meanwhile, the third handrail tube 126 includes a fifth tube segment 1262 and a sixth tube segment 1263 connected and arranged at an angle. The first end of the fifth tube segment 1262 away from the sixth tube segment 1263 is a fourth pivot end 1261B, and the first end of the sixth tube segment 1263 away from the fifth tube segment 1262 is a third pivot end 1261A. When the handrail tube mechanism 120 is in the extended position, each of the third tube segments 1252 and each of the fifth tube segments 1262 are located on the same horizontal plane, and the fourth tube segment 1253 extends downward from the second end of the third tube segment 1252, and the sixth tube segment 1263 extends downward from the second end of the fifth tube segment 1262. Furthermore, the second handrail tube 125 and the third handrail tube 126, which are connected to the first column 111 or the second column 112, are arranged side-by-side in the horizontal direction, and the projection portions of the fifth tube segment 1262 and the third tube segment 1252 on a vertical plane parallel to the front-back direction (BP direction) and perpendicular to the horizontal plane coincide.

[0190] The following is combined with Figure 16 and Figure 18To explain the meaning of the above-mentioned "the second handrail tube 125 and the third handrail tube 126 connected to the first column 111 or the second column 112 are arranged side by side in the horizontal direction, and the projection of the fifth tube segment 1262 and the third tube segment 1252 on the vertical plane that is parallel to the front-back direction (BP direction) and perpendicular to the horizontal plane coincides".

[0191] Figure 16 The illustration schematically shows a bed frame 10 comprising two first uprights 111, two second uprights 112, and a handrail tube mechanism 120, as shown in this embodiment. When the bed frame 10 is in its unfolded state, it is generally square in shape and generally symmetrical both horizontally and vertically. In this embodiment, taking one of the first uprights 111 and the second upright 112 arranged along the front-to-back direction as an example, when the two second handrail tubes 125 and the two third handrail tubes 126 arranged between them are in the unfolded position, the second handrail tubes 125 and the third handrail tubes 126 are arranged side-by-side in the horizontal direction (specifically, in the left-right direction), and the third segment 1252 of the second handrail tube 125 and the fifth segment 1262 of the third handrail tube 126 partially overlap in the left-right direction (see...). Figure 16 and Figure 18 ).

[0192] See Figure 16 and Figure 18 In some embodiments, the second pivot ends 1251A of the two third pipe segments 1252 are arranged side by side in the horizontal direction and their projections on a vertical plane parallel to the front-back direction and perpendicular to the horizontal plane partially overlap. Specifically, taking a first column 111 and a second column 112 arranged in the front-back direction as an example, when the two second handrail pipes 125 arranged between them are in the unfolded position, the second pivot ends 1251A of the two third pipe segments 1252 are arranged side by side in the horizontal direction (specifically, in the left-right direction), and the second pivot ends 1251A of the two third pipe segments 1252 partially overlap in the left-right direction.

[0193] In some embodiments, the included angle α between the third pipe segment 1252 and the fourth pipe segment 1253 is greater than 90°.

[0194] More specifically, in some embodiments, the included angle α between the third pipe segment 1252 and the fourth pipe segment 1253 is 150°. Of course, in some alternative embodiments, the included angle α between the third pipe segment 1252 and the fourth pipe segment 1253 can also be 100°, 120° or 140°, etc., and no specific limitation is made here.

[0195] In some embodiments, the included angle α (not shown in the figure) between the fifth pipe segment 1262 and the sixth pipe segment 1263 is greater than 90°.

[0196] More specifically, in some embodiments, the included angle α between the fifth pipe segment 1262 and the sixth pipe segment 1263 is 150°. Of course, in some alternative embodiments, the included angle α between the fifth pipe segment 1262 and the sixth pipe segment 1263 can also be 100°, 120° or 140°, etc., and no specific limitation is made here.

[0197] See Figure 16 and Figure 18 The second handrail tube assembly 124 also includes, for example, the rotating connecting mechanism 123 described in the first embodiment. Specifically, the rotating connecting mechanism 123 is connected to the second handrail tube 125 and the third handrail tube 126. In this embodiment, a second handrail tube assembly 124 is provided with two rotating connecting mechanisms 123, and the second handrail tube 125 and the third handrail tube 126, which are arranged opposite to each other, are connected by a rotating connecting mechanism 123 along the parallel direction of the second handrail tube 125 and the third handrail tube 126.

[0198] See Figure 16 In some embodiments, the bed frame 10 further includes, for example, the apex corner 130 and the slider 140 described in the first embodiment, and the apex corner 130 has a locking mechanism 150. Referring to the description in the first embodiment, each first column 111 and each second column 112 is provided with an apex corner 130 and a slider 140.

[0199] Specifically, the apex 130 includes a first apex portion 131 and a second apex portion 132, which are connected to each other and arranged at an included angle. Both the first apex portion 131 and the second apex portion 132 are provided with a first pivot portion Q1, which is pivotally connected to a fourth pivot end 1261B. Specifically, the slider 140 includes a first sliding portion 141 and a second sliding portion 142, which are connected to each other and arranged at an included angle. Both the first sliding portion 141 and the second sliding portion 142 are provided with a second pivot portion Q2, which is pivotally connected to a second sliding end 1251B.

[0200] When using the bed frame 10 in this embodiment, when the user needs to switch the bed frame 10 from the unfolded state to the folded state, that is, when the armrest tube mechanism 120 is switched from the unfolded position to the folded position (from... Figure 17 The status shown has switched to Figure 19 When in the state shown, its working process can be described using the handrail tube mechanism 120 set between a first column 111 and a second column 112.

[0201] See Figures 17 to 19The user pushes or pulls the slider 140, causing the slider 140 to move the second sliding end 1251B of the corresponding second handrail tube 125 downwards (in the F1 direction) on the corresponding first column 111 and second column 112. Since in the unfolded state, each third tube segment 1252 is horizontally arranged, the fourth tube segment 1253 extends downwards from the second end of the third tube segment 1252, the fifth tube segment 1262 is horizontally arranged, and the sixth tube segment 1263 extends downwards from the second end of the fifth tube segment 1262, when the second sliding end 1251B moves downwards with the slider 140, the second handrail tube 125 pivots, and the two second pivot ends 1251A rotate relative to each other, causing the two second handrail tubes 125 to move closer together. Simultaneously, as the second armrest tube 125 moves downward, the rotating connecting mechanism 123, in conjunction with the movement of the second armrest tube 125, causes the third armrest tube 126 to rotate downward relative to its corresponding apex 130. The two third pivot ends 1261A rotate relative to each other, bringing the two third armrest tubes 126 closer together, ultimately allowing the first upright 111 and the second upright 112 to come together. By providing the rotating connecting mechanism 123, the user can retract all the armrest tube mechanisms 120 by simply pushing or pulling a single sliding member 140 downwards, thus achieving the folding of the entire children's bed 1000.

[0202] When using the bed frame 10 in this embodiment, when the user needs to switch the bed frame 10 from the folded state to the unfolded state, that is, when the armrest tube mechanism 120 is switched from the folded position to the unfolded position (from... Figure 19 The status shown has switched to Figure 17 When the state shown is as described, its working process can also be described using the handrail tube mechanism 120 set between a first column 111 and a second column 112.

[0203] See Figure 19 The user pushes the slider 140, causing it to move the second sliding end 1251B of the second handrail tube 125 upwards along the corresponding first column 111 and second column 112. At this time, the two second handrail tubes 125 move away from each other, pushing the first column 111 and second column 112 away from each other. During this process, the fourth pivot end 1261B of the two third handrail tubes 126 rotates upwards relative to the first pivot part Q1, and the two third handrail tubes 126 move away from each other, also pushing the first column 111 and second column 112 away from each other. When the two second handrail tubes 125 and the two third handrail tubes 126 are fully extended, the slider 140 can be locked onto the first column 111 and second column 112 by the locking mechanism 150.

[0204] See Figures 20 to 22 The bed frame 10 provided in the second embodiment may further include a second protective component 170. Wherein, Figure 20The partial structure of the bed frame 10 is shown, with the second armrest tube assembly 124 in the unfolded position. Figure 21 Showing Figure 20 The bed frame 10 is in the middle, and the second armrest tube assembly 124 is in the transition position between the unfolded position and the folded position; Figure 22 This shows Figure 20 The bed frame 10 is in the folded position, with the second armrest tube assembly 124 in the retracted position. In this embodiment, the second protective component 170 is disposed on each of the second armrest tubes 125 and / or the third armrest tubes 126. In other words, the second protective component 170 may be disposed only on each of the second armrest tubes 125; or only on each of the third armrest tubes 126; or simultaneously on both the second armrest tubes 125 and the third armrest tubes 126. Further, the second protective component 170 is located at the pivot joint of the second armrest tubes 125 and the third armrest tubes 126 connected to the first column 111 or the second column 112, that is, at the connection between the second armrest tube 125 and the rotating connection mechanism 123; and / or at the connection between the third armrest tube 126 and the rotating connection mechanism 123. When the handrail tube mechanism 120 switches from the extended position to the retracted position, the second handrail tube 125 and the third handrail tube 126, which are connected to the first column 111 or the second column 112, pivot relative to their respective rotating connection mechanisms 123, and together with the corresponding rotating connection mechanisms 123, form a second shearing trap area 128 (see...). Figure 19 The second protective component 170 is used to shield the second shear trap area 128 (see comparison). Figure 19 and Figure 22 In this way, during the folding process of the bed frame 10, not only can the children's bed cover 1200 be prevented from entering the second shearing recess area 128, thus avoiding the impact on the smoothness of folding the bed frame 10, but the user's hands can also be prevented from accidentally entering the second shearing recess area 128, thereby preventing possible pinching injuries.

[0205] like Figure 19 As shown, when the handrail tube mechanism 120 switches from the extended position to the retracted position, the two sixth tube segments 1263 pivot relative to each other and gradually enclose to form the third shear trap zone 129. Specifically, this refers to the area formed by the inner sides of the two sixth tube segments 1263. Specifically, as... Figures 20 to 22 As shown, in this embodiment, the second protective component 170 is disposed on each of the third handrail tubes 126, and when the second protective component 170 is disposed on each of the third handrail tubes 126, the second protective plate 170 extends from the fifth tube segment 1262 to the sixth tube segment 1263. Thus, the second protective component 170 is also used to shield the third shear trap area 129 (see Figure 19 and Figure 22In this way, not only can the child's swaddle 1200 be prevented from entering the third shearing trap 129, but also the hand can be prevented from accidentally entering the third shearing trap 129.

[0206] Specifically, such as Figure 23 As shown, in the second embodiment, the second protective component 170 of the bed frame 10 includes a second protective baffle 171 and a second protective connector 172 connected to each other. The second protective baffle 171 is used to shield the second shearing and clamping area 128 and the third shearing and clamping area 129. In this embodiment, the second protective baffle 171 is generally trapezoidal in shape, and the second protective connector 172 is disposed at the bottom edge and side edge of one side of the second protective baffle 171. In this embodiment, the second protective baffle 171 and the second protective connector 172 are integrally formed. In other embodiments, the second protective baffle 171 and the second protective connector 172 can also be connected by riveting, welding, or other methods. The side of the second protective connector 172 facing away from the second protective baffle 171 forms a second arc-shaped concave surface 1721 that can fit against the outer wall of the second armrest tube 125 and / or the third armrest tube 126. In this embodiment, two second connecting protrusions are spaced apart on one side of the second arc-shaped concave surface 1721, and each second connecting protrusion is provided with a second connecting hole 1722. In other embodiments, the number of second connecting protrusions and second connecting holes 1722 may be more than two or less than two. The corresponding second handrail tube 125 and / or third handrail tube 126 are provided with two second fixing holes (not shown in the figures) respectively opposite to the two second connecting holes 1722. Two fasteners (e.g., rivets, screws, or pins) pass through the corresponding second connecting holes 1722 and second fixing holes to connect the second protective assembly 170 and the second handrail tube 125 and / or the third handrail tube 126. This improves the stability of the second protective assembly 170 after installation. Of course, the second protective plate 170 can also be installed on the second handrail tube 125 and / or the third handrail tube 126 in other ways, such as by snap-fit, etc., without specific limitations.

[0207] like Figure 17 and Figure 18 As shown, when the handrail tube mechanism 120 switches between the extended and retracted positions, the two sixth tube segments 1263 pivot relative to each other and gradually enclose to form a third shear trap region 129. Specifically, this refers to the area formed by the outer sides of the two sixth tube segments 1263. Optionally, in some alternative embodiments, the second protective baffle 171 of the second protective assembly 170 may also be of other shapes. For example, the second protective baffle 171 is generally a rectangular sheet structure. Figure 27 and Figure 28As shown, in one embodiment, the second protective baffle 171 includes a first plate 1711 and a second plate 1712 connected to each other. The first plate 1711 is generally a right-angled trapezoidal sheet structure, and the second plate 1712 is generally a triangular sheet structure. The second plate 1712 is disposed at the oblique side edge of the first plate 1711, so that the entire second protective baffle 171 is generally rectangular. Thus, as... Figures 24 to 26 As shown, when the second protective baffle 171 is installed on each of the third handrail pipes 126, the first plate 1711 can simultaneously block the second shear trap area 128 and the third shear trap area 129, ensuring that the third shear trap area 129 is always blocked. This means that both the third shear trap area 129 inside and outside the sixth pipe section 1263 will be blocked (see...). Figure 18 , Figure 19 , Figure 22 and Figure 26 Specifically, such as Figure 27 and Figure 28 As shown, an arc-shaped groove 1713 is formed at the connection between the first plate 1711 and the second plate 1712. This arc-shaped groove 1713 is used to adapt to the sixth pipe segment 1263 and serves to avoid it, so that after the second protective baffle 171 is installed on the third handrail tube 126, the first plate 1711 and the second plate 1712 can be in the same vertical plane, so as to respectively block the third shear trap area 129 on the inner side and the third shear trap area 129 on the outer side of the sixth pipe segment 1263. Specifically, a second connecting hole 1722 is formed on the groove wall of the arc-shaped groove 1713 and the first plate 1711, respectively. Two fasteners (such as rivets, screws, or pins) pass through the corresponding second connecting holes 1722 and are connected to the sixth pipe segment 1263 and the rotating connecting mechanism 123 (such as the rotating part 1231 or the clamping plate 12321) to connect the second protective component 170 to the third handrail tube 126.

[0208] It should be noted that the "inner side" of the sixth pipe segment 1263 refers to the side of the sixth pipe segment 1263 facing the angle less than 180 degrees formed between it and the fifth pipe segment 1262; the "outer side" of the sixth pipe segment 1263 refers to the side of the sixth pipe segment 1263 facing away from the angle less than 180 degrees formed between it and the fifth pipe segment 1262. In other words, the "inner side" of the sixth pipe segment 1263 refers to the side facing away from the angle less than 180 degrees formed between it and the fifth pipe segment 1262. Figure 24 The lower side of the sixth tube segment 1263 in the deployed state of the handrail tube mechanism shown; the "outer side" of the sixth tube segment 1263 refers to the area where... Figure 24The upper side of the sixth segment 1263 of the handrail tube mechanism in its deployed state is shown. Optionally, in some alternative embodiments, the handrail tube mechanism 120 includes a second handrail tube group 124, which may include only two of the aforementioned second handrail tubes 125. Each second handrail tube 125 has a second pivot end 1251A and a second sliding end 1251B. The two second pivot ends 1251A are pivotally connected, and the two second sliding ends 1251B are slidably disposed on the first column 111 and the second column 112, respectively, and pivotally connected to the first column 111 and the second column 112. When the handrail tube mechanism 120 is in the deployed position, at least a portion of each second handrail tube 125 is parallel to the horizontal plane.

[0209] Alternatively, in some alternative embodiments, the handrail tube mechanism 120 includes a second handrail tube group 124, which may consist of only two of the aforementioned third handrail tubes 126. Each third handrail tube 126 has a third pivot end 1261A and a fourth pivot end 1261B, with the two third pivot ends 1261A pivotally connected and the two fourth pivot ends 1261B pivotally connected to the first column 111 and the second column 112, respectively. When the handrail tube mechanism 120 is in the deployed position, at least a portion of each third handrail tube 126 is parallel to the horizontal plane.

[0210] Figure 29 A perspective view of a bed frame 10 according to a third embodiment of the present invention is shown, which is similar to the first or second embodiment described above. The bed frame 10 includes a plurality of uprights 110 (which can be considered as the first upright 111 and the second upright 112 in the first or second embodiment) and a plurality of armrest tube mechanisms 120. More specifically, the plurality of uprights 110 are spaced apart circumferentially, and an armrest tube mechanism 120 is movably connected between adjacent uprights 110. The armrest tube mechanism 120 is switchable between an unfolded position and a folded position, allowing the bed frame 10 to switch between an unfolded state and a folded state. When the armrest tube mechanism 120 is in the unfolded position, it is at least partially parallel to the horizontal plane. When the bed frame 10 is in the unfolded state, the plurality of uprights 110 are spaced apart from each other (see...). Figure 17 When the bed frame 10 is in the retracted state, the multiple uprights 110 retract into each other.

[0211] In some examples of the third embodiment, the handrail tube mechanism 120 includes at least one of a first handrail tube group 121 and a second handrail tube group 124.

[0212] Specifically, in Figure 29The bed frame 10 shown in the third embodiment includes both a first armrest tube assembly 121 and a second armrest tube assembly 124. Specifically, the first armrest tube assembly 121 can be referred to in the first armrest tube assembly 121 of the bed frame 10 provided in the first embodiment, and the second armrest tube assembly 124 can be referred to in the second armrest tube assembly 124 of the bed frame 10 provided in the second embodiment.

[0213] In some embodiments, such as Figure 29 As shown, the bed frame 10 includes four uprights 110 spaced apart circumferentially. To clearly understand the handrail mechanisms 120 between each upright 110, the four uprights 110 can be referred to sequentially as the first upright 111, the second upright 112, the third upright 113, and the fourth upright 114. A first handrail assembly 121 is provided between the first upright 111 and the second upright 112, and between the third upright 113 and the fourth upright 114, with two first handrail assemblies 121 facing each other. A second handrail assembly 124 is provided between the first upright 111 and the fourth upright 114, and between the second upright 112 and the third upright 113, with two second handrail assemblies 124 facing each other. When the bed frame 10 is in its unfolded state, it has a generally rectangular structure.

[0214] See Figure 29 In some embodiments, the first column 111, the second column 112, the third column 113, and the fourth column 114 are each provided with a apex corner 130 and a sliding member 140. The apex corner 130 includes a first apex corner portion 131 and a second apex corner portion 132, which are connected to each other and arranged at an included angle. Both the first apex corner portion 131 and the second apex corner portion 132 are provided with a first pivot portion Q1. Specifically, one first pivot portion Q1 is pivotally connected to the first pivot end 1221A of the first handrail tube 122, and the other first pivot portion Q1 is pivotally connected to the fourth pivot end 1261B of the third handrail tube 126.

[0215] See also Figure 29 In some embodiments, the slider 140 includes a first sliding portion 141 and a second sliding portion 142, which are connected to each other and arranged at an included angle. Both the first sliding portion 141 and the second sliding portion 142 are provided with a second pivot portion Q2. Specifically, one second pivot portion Q2 is pivotally connected to the first sliding end 1221B of the first handrail tube 122, and the other second pivot portion Q2 is pivotally connected to the second sliding end 1251B of the second handrail tube 125.

[0216] See Figure 30Furthermore, in the third embodiment, the bed frame 10 includes both a first protective component 160 and a second protective component 170. Specifically, the structure and location of the first protective component 160 can be referred to the first protective component 160 in the bed frame 10 provided in the first embodiment; the structure and location of the second protective component 170 can be referred to the second protective component 170 in the bed frame 10 provided in the second embodiment, and will not be repeated here.

[0217] It should be noted that, in the third embodiment, the second protective baffle 171 in the second protective component 170 can have the aforementioned trapezoidal sheet structure (see...). Figure 23 and Figure 30 Of course, it can also take the form of a rectangular sheet structure as described above (see...). Figure 27 and Figure 31 ).

[0218] See Figure 33 and Figure 34 The fourth embodiment of this utility model also provides a bed frame 10, which is a variation of the bed frame 10 shown in the first embodiment above. It includes multiple uprights 110 and multiple armrest tube mechanisms 120. The multiple uprights 110 are spaced apart circumferentially, and an armrest tube mechanism 120 is movably connected between each pair of adjacent uprights 110. Each armrest tube mechanism 120 includes at least one pair of armrest tubes, each pair comprising two armrest tubes that intersect and are pivotally connected. Each armrest tube mechanism 120 is switchable between an unfolded position and a folded position, allowing the bed frame 10 to be switched between an unfolded state and a folded state.

[0219] It should be noted that the "pair of handrail tubes" in the fourth embodiment can refer to two first handrail tubes 122. However, it should be emphasized that these two first handrail tubes 122 are straight tubes, meaning that the first tube segment 1222 and the second tube segment 1223 are on the same straight line. Furthermore, compared to the bed frame 10 in the first embodiment, the bed frame 10 in the fourth embodiment omits the rotating connection mechanism 123. This means that when two first handrail tubes 122 are provided between the two uprights 110, the two first handrail tubes 122 are directly pivotally connected rather than pivotally connected through the rotating connection mechanism 123.

[0220] Further, see Figure 35 and Figure 36 The bed frame 10 in the fourth embodiment also includes a plurality of third protective components 180. Specifically, each pair of armrest tubes is provided with a third protective component 180, and the third protective component 180 is mounted on at least one armrest tube and located at the pivot joint of two armrest tubes. When each armrest tube mechanism 120 switches between an extended position and a retracted position, each third protective component 180 is used to shield the fourth shearing clamping zone α1 formed between the two armrest tubes (i.e., the two first armrest tubes 122) in the corresponding pair of armrest tubes (see Figure 34 In this way, when folding this type of bed frame 10, it is also possible to prevent the child's bed cover 1200 or hands from accidentally entering the fourth shearing and clamping area α1.

[0221] Specifically, see Figure 35 and Figure 36 The third protective component 180 includes a third protective baffle 181 and a third protective connector (not shown in the figures) that are interconnected. The third protective baffle 181 is used to shield the fourth shearing and clamping zone α1. In this embodiment, the third protective baffle 181 is generally rectangular in shape, and the third protective connector is located at one edge of the third protective baffle 181. In this embodiment, the third protective baffle 181 and the third protective connector are integrally formed. In other embodiments, the third protective baffle 181 and the third protective connector can also be connected by riveting, welding, or other methods. The side of the third protective connector facing away from the third protective baffle 181 forms a third arc-shaped concave surface (not shown in the figures) that can fit against the outer wall of the handrail tube. In this embodiment, two third connecting protrusions (not shown in the figures) are spaced apart on one side of the third arc-shaped concave surface, and each third connecting protrusion is provided with a third connecting hole (not shown in the figures). In other embodiments, the number of third connecting protrusions and third connecting holes may be more than two or less than two. The corresponding handrail tube has two third fixing holes (not shown in the attached drawings) that are respectively opposite to the two third connecting holes. Two fasteners (such as rivets, screws, or pins) pass through the corresponding third connecting holes and third fixing holes to connect the third protective component 180 and the handrail tube. This improves the stability of the third protective component 180 after installation. Of course, in some alternative embodiments, the third protective component 180 can also be connected to the handrail tube by snap-fit, or the third protective component 180 can be integrally formed on the handrail tube.

[0222] See Figure 37 and Figure 38 The fifth embodiment of this utility model also provides a bed frame 10, which is a variation of the bed frame 10 shown in the second embodiment above. It includes multiple uprights 110 and multiple armrest tube mechanisms 120. The multiple uprights 110 are spaced apart circumferentially, and an armrest tube mechanism 120 is movably connected between each pair of adjacent uprights 110. Each armrest tube mechanism 120 includes two pairs of armrest tubes, which are pivotally connected to each other. Specifically, each pair of armrest tubes includes two armrest tubes, which intersect and are pivotally connected. Each armrest tube mechanism 120 can be switched between an unfolded position and a folded position, allowing the bed frame 10 to be switched between an unfolded state and a folded state.

[0223] It should be noted that the "pair of armrest tubes" in the fifth embodiment can refer to the second armrest tube 125 and the third armrest tube 126. However, it should be emphasized that the second armrest tube 125 and the third armrest tube 126 are straight tubes, meaning that the third tube segment 1252 and the fourth tube segment 1253 are on the same straight line, and the fifth tube segment 1262 and the sixth tube segment 1263 are on the same straight line. Furthermore, compared with the bed frame 10 in the second embodiment, the bed frame 10 in the fifth embodiment omits the rotating connection mechanism 123, meaning that the second armrest tube 125 and the third armrest tube 126 are directly pivotally connected rather than pivotally connected through the rotating connection mechanism 123.

[0224] Further, see Figure 39 and Figure 40 The bed frame 10 in the fifth embodiment also includes a plurality of third protective components 180. Specifically, each pair of armrest tubes is provided with a third protective component 180, and the third protective component 180 is mounted on at least one armrest tube and located at the pivot joint of the two armrest tubes, that is, the third protective component 180 can be mounted on the second armrest tube 125 and / or the third armrest tube 126. Therefore, when each armrest tube mechanism 120 switches between the extended position and the retracted position, each third protective component 180 can be used to shield the fourth shearing clamping zone α1 formed between the second armrest tube 125 and the third armrest tube 126 (see Figure 34 In this way, when folding this type of bed frame 10, it is also possible to prevent the child's bed cover 1200 or hands from accidentally entering the fourth shearing and clamping area α1.

[0225] This utility model also provides a bed frame 10 (not shown in the figure), which includes multiple uprights 110 and multiple armrest tube mechanisms 120. The multiple uprights 110 are spaced apart circumferentially, and an armrest tube mechanism 120 is movably connected between each pair of adjacent uprights 110. Specifically, for the entire bed frame 10, the armrest tube mechanism 120 includes the armrest tube mechanism 120 in the fourth embodiment and the armrest tube mechanism 120 in the fifth embodiment. In other words, this bed frame 10 can also be considered similar to the bed frame 10 shown in the third embodiment, the only difference being that each first armrest tube 122 in the first armrest tube group 121 is a straight tube, and the second armrest tube 125 and third armrest tube 126 in the second armrest tube group 124 are both straight tubes; and the rotating connection mechanism 123 is omitted. In the first armrest tube assembly 121, the two first armrest tubes 122 are directly pivotally connected; in the second armrest tube assembly 124, the second armrest tube 125 and the third armrest tube 126 are directly pivotally connected. Furthermore, since each armrest tube mechanism 120 of the bed frame 10 is also equipped with a third protective component 180, the bed frame 10 can still prevent the child's bedding 1200 from being pinched or prevent hand injuries during folding. In summary, depending on the type of bed frame 10, different types of protective components (such as the first protective component 160, the second protective component 170, or the third protective component 180, etc.) can be selectively installed on the armrest tubes of the bed frame 10. When each handrail tube mechanism 120 switches between the extended and retracted positions, each protective component is used to shield the shearing and trapping area formed between the two handrail tubes in the corresponding pair (such as the first shearing and trapping area 127, the second shearing and trapping area 128, the third shearing and trapping area 129, the fourth shearing and trapping area α1, etc.). In this way, it can prevent the child's bedding or hands from being trapped.

[0226] The bed frame 10 and children's bed 1000 proposed in this utility model have at least the following technical effects:

[0227] In the bed frame 10 and children's bed 1000 of this utility model, by movably connecting the armrest tube mechanism 120 between the first upright 111 and the second upright 112, the armrest tube mechanism 120 can have an unfolded position and a folded position. When the armrest tube mechanism 120 is in the folded position, the entire bed frame 10 can be in a folded state, so that the bed frame 10 is smaller in size for easy storage and transportation. When the armrest tube mechanism 120 is in the unfolded position, it is at least partially parallel to the horizontal plane. Therefore, when the armrest tube mechanism 120 is in the unfolded position, the children's bed cover (e.g., a cloth cover) installed on the armrest tube mechanism 120 tends to be flat, so that it fits the armrest tube mechanism 120 better, and thus the bed frame 10 covered with the children's bed cover has a neater appearance. In other words, when the bed frame according to this utility model and the children's bed 1000 including the bed frame are in the unfolded state, the upper surface of the armrest tube component is flat, so that the children's bed covering laid on the bed frame is more flat and smooth.

[0228] The bed frame 10 and children's bed 1000 proposed in another aspect of this utility model have at least the following technical effects:

[0229] In the bed frame 10 and children's bed 1000 of this utility model, regardless of the construction of the bed frame 10 (for example, the upper end of the armrest tube mechanism 120 is flush, or the first armrest tube 122, the second armrest tube 125 and the third armrest tube 126 can all be straight tubes, etc.), protective components can be set to cover the shearing and trapping area (for example, the first protective component 160 is set to cover the first shearing and trapping area 127, the second protective component 170 is set to cover the second shearing and trapping area 128 and the third shearing and trapping area 129, or the protective component 180 is set to cover the fourth shearing and trapping area α1). This prevents the children's bed cover 1200 from entering the shearing and trapping area during the folding process of the bed frame 10, thus avoiding the impact on the smoothness of the folding of the bed frame 10, and also prevents the user's hands from accidentally entering the shearing and trapping area, thereby preventing possible pinching injuries.

[0230] See back Figures 1 to 4The crib cover 1200 of the children's bed 1000 may include a generally rectangular bottom support piece 1210 and four side support pieces 1220 respectively connected to the four sides of the bottom support piece 1210. The shape of the bottom support piece 1210 is adapted to the horizontal cross-sectional shape of the bed frame 10 in its unfolded state. For example, in this embodiment, both the horizontal cross-sectional shape of the bed frame 10 in its unfolded state and the bottom support piece 1210 are rectangular. More specifically, each side support piece 1220 is connected between a corresponding first upright 111 and a second upright 112, that is, a side support piece 1220 is connected between each first upright 111 and each second upright 112. The bottom support piece 1210 is connected to two first uprights 111 and two second uprights 112. The bottom support piece 1210 and the four side support pieces 1220 enclose a receiving cavity.

[0231] In some embodiments, the crib cover 1200 may further include a protective element 1230. The protective element 1230 is connected to the end of each side support piece 1220 away from the bottom support piece 1210, and is fitted onto each armrest tube mechanism 120. By connecting the bottom support piece 1210 and the side support pieces 1220 to the bed frame 10, a space for the crib 1000 to accommodate children can be defined, within which children can play. Furthermore, the protective element 1230 fitted onto the armrest tube mechanism 120 prevents the armrest tube mechanism 120 from being exposed, thus avoiding bumps and dents, and also improves the aesthetics of the crib 1000. The protective element 1230 may be made of a flexible material. For example, the protective element 1230 may be a fabric cover.

[0232] In some embodiments, the side support sheet 1220 may be a sheet of fabric, a sheet of mesh, etc., and is not specifically limited herein. Furthermore, when the side support sheet 1220 is a sheet of mesh, the side support sheet 1220 may be considered to be transparent, allowing the user to observe the child's situation in the accommodating space from outside the bed frame 10 at any time.

[0233] Furthermore, in some embodiments, an operating element 1300 is provided at approximately the center of the bottom support piece 1210 (e.g., Figure 1 , Figure 2 and Figure 41 (As shown in the diagram). For example, the operating element 1300 can be a structure such as webbing, rope, or loop (e.g., a rigid pull ring, handle, or hook). In this embodiment, the operating element 1300 can be a webbing pull ring. The operating element 1300 can be operated to switch the bed frame 10 from an unfolded state to a folded state.

[0234] When a user needs to switch the children's bed 1000 from the unfolded state to the folded state, the user presses the operating end 1511 to release the locking member 151; then, the user pulls the operating member 1300 upward or pushes or pulls the sliding member 140 in the F1 direction. In this way, with the cooperation of the armrest tube mechanism 120, the top corner 130 and the sliding member 140, the first uprights 111 and the second uprights 112 included in the bed frame 10 can be brought closer to each other, thereby folding the children's bed 1000.

[0235] See Figures 1 to 4 as well as Figure 41 and Figure 43 In some embodiments, the children's bed 1000 also includes a hammock 200. The hammock 200 is detachably connected to the bed frame 10 and installed within the bed frame 10. Of course, in some alternative embodiments, the hammock 200 may also be fixedly connected to the bed frame 10. In one embodiment of the present invention, the hammock 200 may be accommodated within a receiving cavity formed by a bottom support piece 1210 and four side support pieces 1220.

[0236] See Figure 1 In one embodiment, the hammock 200 is provided with an operation opening 201, which is positioned opposite to the operating component 1300. When the user needs to switch the children's bed 1000 from the unfolded state to the folded state, their hand can pass through the operation opening 201 and pull the operating component 1300 upwards. The upward movement of the operating component 1300 causes the bottom support plate 1210 to fold upwards, and the folding of the bottom support plate 1210 causes the four uprights to fold, thereby switching the children's bed 1000 to the folded state. When the children's bed 1000 is in the unfolded state, a mattress can be placed in the hammock 200 to cover the operation opening 201, making it convenient to support infants and young children. Both the hammock 200 and the children's bed have a small volume when folded, making them easy to store and transport.

[0237] Specifically, such as Figure 41 and Figure 43As shown, the hammock 200 includes a hammock cover 210 and a support assembly 220 supported on the bottom of the hammock cover 210. The hammock cover 210 includes a generally rectangular bottom cover 211 and four side covers 212 respectively connected to the four sides of the bottom cover 211. The bottom cover 211 and the four side covers 212 form a receiving cavity 230 for accommodating the mattress 300 and the infant. In this embodiment, the four side covers 212 are detachably connected to the four side support pieces 1220 by zippers 240. In other embodiments, the four side covers 212 can also be detachably connected to the four side support pieces 1220 by means of button fastening, Velcro fastening, etc., or directly fixed connection. The bottom cover 211 has a first opening 2111 opposite to the operating member 1300 at approximately the center position. In this embodiment, the hammock covering 210 is made of mesh fabric, making the entire hammock 200 lighter and more breathable. In other embodiments, the hammock covering 210 may also be made of other lightweight and breathable non-mesh fabric materials.

[0238] Specifically, such as Figures 43 to 45 As shown, the support assembly 220 includes a pivot seat 221 and a plurality of support tube assemblies 222 circumferentially pivotally connected to the pivot seat 221. In this embodiment, the pivot seat 221 is generally annular in shape, and a second opening 2211 is formed in the middle of the pivot seat 221. The second opening 2211 is opposite to the first opening 2111 and the operating member 1300, that is, the operating port 201 of this utility model may include the second opening 2211 and the first opening 2111. The operator can operate the operating member 1300 through the second opening 2211 and the first opening 2111. The pivot seat 221 includes a first surface 2212 facing away from the bottom cover 211 (e.g., ...). Figure 45 (as shown) and the second surface 2213 facing the bottom cover 211 (as shown) Figure 46 (As shown). The second surface 2213 of the pivot seat 221 is provided with a plurality of pivot components 2214, each pivot component 2214 including two pivot members 2214a arranged relatively apart. In this embodiment, there are four pivot components 2214, and the support tube group 222 has four corresponding groups and is pivotally connected to the four pivot components 2214 respectively.

[0239] Furthermore, when the hammock 200 is in the unfolded state, the length of each support tube assembly 222 is less than the length of each column 110. Thus, the shorter length of each support tube assembly 222 results in a smaller gravitational torque on each assembly, leading to better support stability for the entire support component 222.

[0240] Specifically, each support tube assembly 222 includes multiple interconnected tube segments, which are at least partially retractable into each other. It should be understood that "multiple" in this document refers to at least two. In this embodiment, as... Figures 43 to 45 As shown, each support tube assembly 222 includes an inner support tube 2221 and an outer support tube 2222 slidably sleeved outside the inner support tube 2221. The inner support tube 2221 has a first end 2221a and a second end 2221b, and the outer support tube 2222 has a third end 2222a and a fourth end 2222b. The first end 2221a of the inner support tube 2221 is pivotally connected to the corresponding pivot assembly 2214. The second end 2221b of the inner support tube 2221 is inserted into the outer support tube 2222 via the third end 2222a of the corresponding outer support tube 2222 and slidably sleeved with the outer support tube 2222. The fourth end 2222b of the outer support tube 2222, away from the pivot seat 221, is connected to the hammock covering 210. In other embodiments not shown, each support tube assembly 222 includes a first tube segment, a second tube segment, and a third tube segment connected sequentially from near the pivot 221 to away from the pivot 221, wherein the second tube segment can be folded together with the first tube segment, or the second tube segment can be folded together with the third tube segment. Of course, the present invention is not limited to this, and the support tube assembly 222 can also be folded together by means other than sliding or folding.

[0241] In this embodiment, as Figure 43 and Figure 44 As shown, the fourth ends 2222b of the four support tube assemblies 222 are respectively connected to the four apex corners of the bottom covering 211. Specifically, each of the four apex corners of the bottom covering 211 is provided with a sleeve 2112 extending towards the center of the bottom covering 211. In this embodiment, the sleeve 2112 is sewn onto the bottom covering 211 using the same mesh fabric material as the bottom covering 211. The outer support tube 2222 of each support tube assembly 222 is inserted into the sleeve 2112 and is fixedly connected to the sleeve 2112 by fasteners 2113 such as rivets. In this embodiment, the length of the sleeve 2112 is the same as the length of the outer support tube 2222. This design serves two purposes: firstly, it avoids the sleeve 2112 from being too long and affecting the extension and retraction of the support tube assembly 222; secondly, it ensures that the sleeve 2112 has sufficient length so that the support tube assembly 222 does not swing irregularly during the folding or unfolding of the children's bed 1000, thus preventing it from affecting the folding and unfolding.

[0242] like Figures 45 to 47As shown, the support tube assembly 222 can switch between an extended state and a shortened state. In this embodiment, the extended state of the support tube assembly 222 refers to the state where the first end 2221a of the inner support tube 2221 and the fourth end 2222b of the outer support tube 2222 are farthest apart, and the shortened state of the support tube assembly 222 refers to the state where the first end 2221a of the inner support tube 2221 and the fourth end 2222b of the outer support tube 2222 are closest together. When the support tube assembly 222 is in the extended state, the inner support tube 2221 extends at least partially out of the outer support tube 2222. When the support tube assembly 222 is in the shortened state, the inner support tube 2221 retracts into the outer support tube 2222, that is, the inner support tube 2221 is completely hidden within the outer support tube 2222. Of course, in other embodiments, the inner support tube 2221 does not necessarily have to be completely hidden within the outer support tube 2222, that is, a portion of the inner support tube 2221 may be hidden within the outer support tube 2222. When the support tube assembly 222 is in a shortened state, the distance between the first end 2221a of the inner support tube 2221 and the fourth end 2222b of the outer support tube 2222 is less than the distance between them when the support tube assembly 222 is in an extended state.

[0243] In this embodiment, both the inner and outer tubes are hollow tubular structures. The length of the outer supporting tube 2222 is greater than or equal to the length of the inner supporting tube 2221, so that when the supporting tube assembly 222 is in a shortened state, the inner supporting tube 2221 is completely retracted into the outer supporting tube 2222. In this embodiment, the length of the outer supporting tube 2222 is slightly greater than the length of the inner supporting tube 2221 to ensure that the inner supporting tube 2221 is retracted into the outer supporting tube 2222 to the maximum extent. In other embodiments, the lengths of the outer supporting tube 2222 and the inner supporting tube 2221 can also be adjusted according to the size of the children's bed and the folding configuration. Figure 48 and Figure 49 As shown, when the children's bed is in the folded state, multiple support tube assemblies 222 pivot relative to the pivot seat 221 to a position approximately below the pivot seat 221, and simultaneously switch to a retracted state. This results in a smaller volume, facilitating storage and transportation. The hammock 200 is installed within the bed frame 10 and can switch between an unfolded and folded state. One or more armrest tube mechanisms 120 of the bed frame 10 can form the top frame 1110 of the bed frame 10. When the hammock 200 is in the folded state, the folded height of the support assembly 220 is lower than the height of the highest point of the top frame 1110. That is, the length of the outer support tube 2222 is less than or equal to the vertical distance from the bottom covering 211 to the highest point of the top frame 1110 when the hammock 200 is in the unfolded state, thus reducing the overall height of the children's bed when folded.

[0244] The structure of one of the support components 220 is described in more detail below:

[0245] like Figure 50 and Figure 51 As shown, the support assembly 220 also includes an anti-contact assembly 223, which is disposed between the inner support tube 2221 and the outer support tube 2222 to prevent direct contact between the two. Specifically, the anti-contact assembly 223 includes a first anti-contact element 2231 disposed on the inner support tube 2221 and a second anti-contact element 2232 disposed on the outer support tube 2222, with both the first anti-contact element 2231 and the second anti-contact element 2232 being at least partially located between the inner support tube 2221 and the outer support tube 2222.

[0246] The anti-contact component 223 is provided so that only the first anti-contact component 2231 partially contacts the outer support tube 2222, and only the second anti-contact component 2232 partially contacts the inner support tube 2221. The inner support tube 2221 and the outer support tube 2222 do not directly contact each other, resulting in a small contact area and smooth sliding. Furthermore, both the first anti-contact component 2231 and the second anti-contact component 2232 can be made of plastic material, reducing friction between them and further enhancing the relative sliding between them.

[0247] like Figure 54 and Figure 55 As shown, the first anti-contact member 2231 includes a first insertion portion 2231a and a first abutment portion 2231b connected to each other. The first insertion portion 2231a is generally cylindrical, and a first engaging finger 2231c is provided on the side wall of the first insertion portion 2231a. The first abutment portion 2231b is generally frustum-shaped, with a radial dimension larger than that of the first insertion portion 2231a. The first abutment portion 2231b is integrally formed with the first insertion portion 2231a, and the first abutment portion 2231b closes one end of the first insertion portion 2231a. The first abutment portion 2231b is fixed to one end of the first insertion portion 2231a and closes one end of the first insertion portion 2231a. A first engaging hole 2221c is provided on the inner support tube 2221. When the first anti-contact member 2231 is installed on the inner support tube 2221, the first insertion part 2231a is inserted into the inner support tube 2221 through the second end 2221b of the inner support tube 2221, and the first engaging finger 2231c engages with the first engaging hole 2221c, thereby fixing the first anti-contact member 2231 to the inner support tube 2221. The first abutting part 2231b is located outside the inner support tube 2221 and closes the second end 2221b of the inner support tube 2221. The radial dimension of the first abutting part 2231b is larger than the outer diameter of the inner support tube 2221.

[0248] like Figure 55As shown, the second anti-contact member 2232 includes a second insertion portion 2232a and a second abutment portion 2232b connected to each other. The second insertion portion 2232a is generally cylindrical, and a second engaging finger 2232c is provided on the side wall of the second insertion portion 2232a. The second abutment portion 2232b is generally a boss structure integrally formed on one end of the first insertion portion 2231a. Alternatively, the second abutment portion 2232b is generally a boss structure fixed to one end of the first insertion portion 2231a. A second engaging hole 2222c is provided on the supporting outer tube 2222 (see...). Figure 48 and Figure 49 When the second anti-contact member 2232 is installed on the support outer tube 2222, the second insertion part 2232a is inserted into the support outer tube 2222 through the third end 2222a of the support outer tube 2222, and the second engaging finger 2232c engages with the second engaging hole 2222c, thereby fixing the second anti-contact member 2232 to the support outer tube 2222.

[0249] Furthermore, such as Figure 50 and Figure 51 As shown, the fourth end 2222b of the supporting outer tube 2222 is also provided with an end cap 224, which is at least partially inserted into the supporting outer tube 2222 to close the supporting outer tube 2222.

[0250] Furthermore, when the hammock 200 is in the extended state, the support tube assembly 222 is in the extended state; when the hammock 200 is in the retracted state, the support tube assembly 222 is in the shortened state. When the support tube assembly 222 is in the extended state, as... Figure 51 As shown, the first abutting portion 2231b of the first anti-contact member 2231 and the second insertion portion 2232a of the second anti-contact member 2232 abut and limit the contact. This limits the maximum elongation of the support tube assembly 222 and prevents the inner support tube 2221 from detaching from the outer support tube 2222. When the hammock 200 is in the retracted state, the first abutting portion 2231b of the first anti-contact member 2231 and the end cap 224 abut and limit the contact. Alternatively, the third end 2222a of the outer support tube 2222, i.e., the end of the outer support tube 2222 where the second anti-contact member 2232 is inserted, can abut and limit the contact with the pivot seat 221.

[0251] The folding process of the children's bed in this embodiment is described in detail below:

[0252] When the crib is folded up, after the locking element 151 is released as described above, the four uprights 110 are in the unlocked state, as follows: Figure 41As shown, the operating member 1300 can be pulled upward through the first opening 2111 and the second opening 2211, causing the bottom support piece 1210 to retract towards the operating member 1300, i.e., towards the center position, and be lifted upward. Simultaneously, the bottom support piece 1210 pulls the four columns 110 together towards the center position. In this way, on the one hand, the bottom support piece 1210 is retracted between the four columns 110 in the retracted state and will not fall downward; on the other hand, the upwardly pulled bottom support piece 1210 simultaneously generates an upward thrust on the pivot seat 221, allowing the support assembly 220 to retract well, i.e., the support tube assembly 222 can pivot downward relative to the pivot seat 221, and simultaneously contract under the pushing action of the bottom support piece 1210 and the bottom covering 211. Figure 49 The state shown. Therefore, the children's bed... Figure 56 The intermediate state shown gradually converges to Figure 57 The folded state shown. After the crib is folded, as shown... Figure 58 As shown, the folded children's bed can be wrapped in a mattress 300 and secured with straps 310 on the mattress 300. Since the folded height of the support assembly 220 is lower than the highest point of the top frame 1110 when the hammock 200 is folded, the folded hammock 200 is enclosed within the children's bed, and since the highest point of the hammock 200 is lower than the top frame 1110, the folded hammock 200 does not affect the folded size of the children's bed, ensuring a smaller folded volume.

[0253] In an embodiment not shown, the operating element 1300 may be omitted. When the children's bed is folded, the four uprights 110 can be released and external force applied to make them close together. However, the bottom support plate 1210 may fall downwards under gravity, requiring manual lifting to fold it back together. During the folding process, the support tube assembly 222 will not automatically pivot downwards and retract relative to the pivot seat 221. In this case, the support assembly 220 will hinder the overall folding of the children's bed. Therefore, it is necessary to manually lift the pivot seat 221 to rotate and retract the support tube assembly 222 relative to the pivot seat 221 before the children's bed can be folded to the folded state.

[0254] In this embodiment, during the folding process of the crib, after the support tube assembly 222 pivots downward relative to the pivot seat 221, the inner support tube 2221 of the support tube assembly 222 can automatically slide into the outer support tube 2222, that is, the support tube assembly 222 can automatically retract, so that the folded height of the support component 220 is lower than the height of the highest point of the top frame 1110. In other embodiments, during the folding process of the crib, after the support tube assembly 222 pivots downward relative to the pivot seat 221, the inner support tube 2221 of the support tube assembly 222 will not automatically slide into the outer support tube 2222. In this case, external force needs to be applied to make the inner support tube 2221 slide into the outer support tube 2222, so that the support tube assembly 222 retracts, so that the folded height of the support component 220 is lower than the height of the highest point of the top frame 1110.

[0255] The aforementioned children's bed and hammock 200 have at least the following technical effects:

[0256] The aforementioned children's bed includes a bed frame and a hammock. The bed frame includes a top frame, and the hammock includes a hammock cover and a support assembly. When the hammock is installed inside the bed frame, the children's bed can be switched between an unfolded and a folded state. When the children's bed is in the folded state, the folded height of the support assembly is lower than the height of the highest point of the top frame, thus making the hammock 200 have a small volume when folded, facilitating storage and transportation.

[0257] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0258] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
