DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0006] The present disclosure will be further described below with the aid of embodiments and drawings.Before describing the present disclosure in detail, it should be noted that similar symbols in the drawings represent similar elements.In addition, the terms "first", "second" and "third" referred to in the present disclosure are only used to distinguish different embodiments, not to indicate the priority of the embodiments.

[0007] First embodiment 1 to 3, a baby bed 100 according to a first embodiment of the present disclosure includes a main body 1 and a support frame 2 supporting the main body 1. The support frame 2 includes a lower frame 2A, an upper frame 2B, and an operation module 23. The lower frame 2A stands on a flat surface (e.g., the ground) and has a lower support rod 21. The upper frame 2B is connected to the main body 1 and includes an upper support rod 22. The operation module 23 is connected to the lower support rod 21 and the upper support rod 22. The upper support rod 22 and the lower support rod 21 are sleeved together. The upper support rod 22 can move up and down relative to the lower support rod 21, and the height of the main body 1 can be adjusted. The operation module 23 is configured to lock and unlock the upper support rod 22 and the lower support rod 21.

[0008] In this embodiment, the lower frame 2A has two lower support rods 21. Each of the lower support rods 21 has a hollow, upright outer tube segment 211 and a lower support segment that is bent downward and extends from the outer tube segment 211 so as to stand on a plane. The upper frame 2B has two upper support rods 22. Each of the upper support rods 22 has an upright inner tube segment 221 and an upper support segment 222 that is bent upward and extends from the inner tube segment 221 to connect and support the main body 1. The outer tube segment 211 and the inner tube segment 221 are located below the side of the main body 1. Two connecting rods 20 connect the two outer tube segments 211 and the two inner tube segments 221, respectively, to increase the support strength.

[0009] 3 to 6, the outer tube segments 211 of the lower support rod 21 are arranged side by side, and each of the outer tube segments 211 has a tube opening 2111 at the top, and the opening 2112 faces the other outer tube segments 211. The inner tube segment 221 of the upper support rod 22 is inserted into the outer tube segment 211 from the tube opening 2111 and can slide up and down relative to the outer tube segment 211, and the height of the main body 1 can be adjusted by adjusting the length extending from the tube opening 2111 or the length stored in the tube opening 2111 (as shown in FIG. 1). Each of the inner tube segments 221 has a plurality of locking portions 2211 arranged in the vertical direction, and one position of the locking portion 2211 corresponds to the opening 2112. In the first embodiment, the opening 2112 and the locking portion 2211 are vertically elongated holes extending in the vertical direction. The support frame 2 further includes two anti-slip sleeves 28 and two holding members 29. A slip-prevention sleeve 28 is sleeved onto the lower end of the inner tube segment 221. A retaining member 29 is positioned over the tube opening 2111 against which the slip-prevention sleeve 28 abuts to prevent the inner tube segment 221 from separating from the outer tube segment 211.

[0010] The operation module 23 includes a fixed base 24 , two locking members 25 , a restoring member 26 , and an unlocking member 27 .

[0011] The fixed base 24 is connected to the outer tube segment 211, and the position of the fixed base 24 corresponds to the opening 2112. In the first embodiment, the fixed base 24 has two sleeve parts 241 arranged on the outer tube segment 211 and an attachment part 242 connected to the sleeve parts 241. The attachment part 242 has a transverse accommodating groove 243 extending in the left-right direction and communicating with the opening 2112, and a longitudinal accommodating groove 244 extending in the up-down direction and communicating with the transverse accommodating groove 243. The locking member 25 and the returning member 26 are accommodated in the transverse accommodating groove 243. The unlocking member 27 is accommodated in the longitudinal accommodating groove 244 and partially extends from the attachment part 242 for pressing.

[0012] The locking members 25 are disposed on the fixed base 24 and are movable between a locked position (position shown in FIG. 4) and an unlocked position (position shown in FIG. 6). Each of the locking members 25 has an interfering portion 251 that extends into the corresponding opening 2112 to engage with one of the locking portions 2211 at the locked position, and a drive portion 252 for the unlocking member 27 to drive. In other words, when the position of one of the locking portions 2211 of the inner tube segment 221 is aligned with the opening 2112, the corresponding interfering portion 251 can pass through the opening 2112 and extend into the locking portion 2211 aligned with the opening 2112. Thus, when the locking member 25 is located at the locked position, the interfering portion 251 extends into the locking portion 2211 to restrain the inner tube segment 221 from moving downward. In this embodiment, the drive portion 252 has an inclined slot 253. Two inclined slots are arranged symmetrically in a direction gradually approaching each other from top to bottom. The return member 26 is connected to the lock member 25 and returns the lock member 25 to the lock position. In the first embodiment, the return member 26 is a compression spring, and the opposite ends of the return member 26 abut against the two lock members 25, respectively. The lock member 25 and the return member 26 are accommodated in the horizontal accommodation groove 243, and the lock member 25 can move linearly only in the left-right direction.

[0013] The unlocking member 27 is disposed on the fixed base 24 and can be pressed. The unlocking member 27 has two pin parts 271 that can slide along the inclined slot 253. The unlocking member 27 is pressed to move in the up-down direction, and drives the locking member 25 to approach each other in the left-right direction by sliding along the inclined slot 253 via the pin parts 271, and moves from the locked position to the unlocked position. As a result, the interference part 251 is disengaged from the locking part 2211. In the first embodiment, the unlocking member 27 is accommodated in the vertical accommodation groove 244 and partially extends from the mounting part 242 due to the pressing. The unlocking member 27 is restrained by the vertical accommodation groove 244, so that the unlocking member 27 can only move linearly in the up-down direction. As shown in FIG. 4, before the unlocking member 27 is pressed, the locking member 25 is located at the locked position, and the pin part 271 is located at the lower end of the inclined slot 253. When a user pushes the unlocking member 27 from bottom to top, the unlocking member 27 moves upward, and the pin part 271 also moves upward at the same time. When the pin part 271 moves upward, it presses the inner wall of the inclined slot 253 and slides along the inclined slot 253, thereby driving the locking members 25 to approach each other in the left-right direction. As shown in Fig. 6, when the pin part 271 moves to the upper end of the inclined slot 253, the locking members 25 move to the unlocked position and the engagement between the interference part 251 and the locking part 2211 is released. At this time, the upper support rod 22 can move freely in the up-down direction.

[0014] In the first embodiment, the interference portion 251 has a downward inclined surface 2511. When the inner tube segment 221 is moved upward, the locking portion 2211 moves against the inclined surface 2511, and pushes the inclined surface 2511 to move the locking member 25 toward the unlocked position, thereby releasing the engagement between the locking portion 2211 and the interference portion 251. In other words, when the user wants to adjust the main body 1 upward, the user does not need to press the unlocking member 27 to move the locking member 25 to the unlocked position. The user can directly pull the upper support rod 22 upward to bias the inclined surface 2511 of the interference portion 251 by the lower edge of the locking portion 2211, and push the interference portion 251 out of the locking portion 2211. The interference portion 251 is returned by the return member 26 until the next locking portion 221 is aligned with the opening 2112, and extends to the next locking portion 221 to achieve auto-lock. When the user wants to adjust the main body downward, he / she needs to press the unlocking member 27 to move the locking member 25 to the unlocked position. After the main body 1 is lowered to the appropriate height and the corresponding locking portion 2211 is aligned with the opening 2112, the user can release the unlocking member 27, and the locking member 25 can return to the locked position to lock the upper support rod 22.

[0015] Second embodiment 7 to 9, the baby bed 100 of the second embodiment of the present disclosure is substantially the same as the first embodiment, but has some differences in the operation module 23. In the second embodiment, the outer tube segment 211 of the lower support rod 21 does not have an opening 2112, and the tube opening 2111 is disposed in the fixed base 24. The fixed base 24 has a casing 245, two pivots 246, and a positioning plate 247. The casing 245 forms a storage space. The two pivots 246 are disposed in the casing 245 adjacent to the holding member 29, and extend from the casing 245 in the front-rear direction. The positioning plate 247 is disposed in the casing 245 and abuts against the upper surface of the holding member 29. The locking member 25 is disposed relative to the pivot 246. Each of the locking members 25 has a pivot portion 254 and an interference portion 251. The pivot portion is sleeved in the pivot 246. The interference portion 251 extends from the pivot portion 254 and abuts against the upper surface of the holding member 29 in the locked position. The unlocking member 27 has an avoidance groove 272 through which the pivot 246 passes, a restraining hole 273 through which the interference portion 251 passes, and a restraining groove 274 extending in the vertical direction and configured to accommodate the return member 26. When the unlocking member 27 is pressed, the unlocking member 27 moves upward, and the interference portion 251 is driven to rotate upward as the restraining hole 273 moves upward. The return member 26 is a compression spring, and the opposite end of the return member 26 abuts against the casing 245 and the unlocking member 27, respectively. For convenience of explanation, the front half of the fixed base 24 shown in FIG. 7 is omitted. The upper end of the return member 26 may abut against the lower side of a stud (not shown) for fixing the bolt 3.

[0016] In the second embodiment, when the user wants to adjust the main body 1 upward, the user can directly pull the upper support rod 22 upward, drive the interference part 251 to rotate upward by the lower end of the lock part 2211, and release the interference part 251 from the lock part 2211. At the same time, the interference part 251 moves the unlocking member 27 upward to compress the return member 26, and drives the return member 26 to store elastic force. When the next lock part 2211 is aligned with the interference part 251, the interference part 251 extends into the lock part 2211, and a space is created for the interference part 251 to rotate downward. At the same time, the unlocking member 27 is returned by the return member 26, and drives the interference part 251 to return. When the interference part 251 is located at the lock position, the interference part 251 extends into the corresponding lock part 2211, and the upper edge of the lock part 2211 abuts against the interference part 251, preventing the upper support rod 21 from moving downward. In addition, the lower surface of the interference portion 251 abuts against the upper surface of the holding member 29 supported by the lower support rod 21, enhancing the support strength. When the user wants to adjust the main body 1 downward, the user can pull the upper support rod 22 upward to move the upper edge of the locking portion 2211 away from the interference portion 251 and provide space for the interference portion 251 to rotate. Then, the user can press the unlocking member 27 to rotate the interference portion 251 upward to the unlocked position. After the main body 1 is lowered to the appropriate height and the corresponding locking portion 2211 is aligned with the interference portion 251, the user can release the unlocking member 27 so that the interference portion 251 returns to the locked position to lock the upper support rod 22.

[0017] In the second embodiment, the positioning plate 247 and the interference portion 251 in the locked position abut indirectly against the upper surface of the holding member 29 and against the end face of the lower support rod 21. In another embodiment, in the absence of the holding member 29, the positioning plate 247 and the interference portion 251 in the locked position may abut directly against the end face of the lower support rod 21. Thus, the positioning plate 247 and the interference portion 251 in the locked position may abut directly or indirectly against the end face of the lower support rod 21.

[0018] Third embodiment 10 and 11, the baby cot 100 of the third embodiment of the present disclosure is substantially the same as the first embodiment. However, in the third embodiment, the upper support rod 22 is sleeved on the outside of the lower support rod 21, and the joint structure is upside down compared to the first embodiment. That is, in the first embodiment, after the upper support rod 22 and the lower support rod 21 are sleeved together, the lower support rod 21 is located on the outside and the upper support rod 22 is located on the inside, whereas in the third embodiment, after the upper support rod 22 and the lower support rod 21 are sleeved together, the upper support rod 22 is located on the outside and the lower support rod 21 is located on the inside. Furthermore, the structure disposed on the outer tube segment 211 of the lower support rod 21 in the first embodiment and the structure disposed on the inner tube segment 221 of the upper support rod 22 are upside down in the third embodiment. That is, the upper support rod 22 in the third embodiment has the same structure as the outer tube segment 211 in the first embodiment, and the lower support rod 21 in the third embodiment has the same structure as the inner tube segment 221 in the first embodiment.

[0019] Similarly, in the third embodiment, the operation module 23 is disposed on the upper support rod 22 upside down compared to the first embodiment, and moves up and down together with the upper support rod 22. Furthermore, in the third embodiment, the operation and principle of the operation module 23 are substantially the same as those of the first embodiment, and only the pressing direction of the unlocking member 27 is from top to bottom, which is the opposite to that of the first embodiment. Also, when the user wants to adjust the main body 1 (shown in FIG. 1) upward, in the third embodiment, the user does not need to press the unlocking member 27 either, and the user may directly pull the upper support rod 22 upward to bias the inclined surface 2511 of the interference part 251 by the upper edge of the lock part 2211, and push the interference part 251 out of the lock part 2211. Until the interference part 251 moves to the next lock part 221, the interference part 251 is returned by the return member 26, and extends to the next lock part 221 to realize auto-lock.

[0020] Similarly, in a variation of the second embodiment, the upper support rod 22 may also be sleeved onto the outside of the lower support rod 21, with the joint structure being upside down compared to the second embodiment.

[0021] As described above, the operation module 23 can be located in the center of the long side of the main body 1, which is convenient for the user to operate. Furthermore, the overall structure of the support frame 2 is simple and easy to manufacture, and the weight of the support frame 2 can be lightened to facilitate transportation and movement.
