A frame folding mechanism 30 of the crib frame 1 may be connected to the frame portion 10 and the supporting portion 20, respectively, so as to operate the supporting portion 20 to be easily folded, and stably hold the supporting portion 20 in the unfolded position or the folded position.
The frame folding mechanism 30 may include a transverse rod 320 positioned below the frame portion 10; a connecting rod 310 having a right end (without limitation, see
The transverse rod 320 may be centrally disposed below a lower surface of the frame portion 10 in the longitudinal direction of the frame portion 10 (i.e., a left-right direction in
The transverse rod 320 may be formed with a folding fixing groove 321 and an unfolding fixing groove 322 (as shown in
Optionally, the transverse rod 320 may also be provided with any fixing groove other than the folding fixing groove 321 and the unfolding fixing groove 322, so that the supporting portion 20 can be kept at a desired angle or position as required.
In this embodiment, each side of the transverse rod 320 has a folding fixing groove 321 and an unfolding fixing groove 322. The number of the folding fixing groove 321 and the unfolding fixing groove 322 is not limited in the present application. Correspondingly, in this embodiment, the frame folding mechanism 30 may have two connecting rods 310 and two clamping assemblies 330. The number of connecting rod 310 and clamping assembly 330 is not limited in the present application. Optionally, the transverse rod 320 may have another number of folding fixing groove 321 and unfolding fixing groove 322, and the frame folding mechanism 30 may have another number of connecting rod 310. Optionally, the number of the folding fixing groove 321 and the unfolding fixing groove 322 corresponds to the number of the connecting rod 310 and the number of the clamping assembly 330. In this embodiment, the frame folding mechanism 30 has one transverse rod 320. Optionally, the frame folding mechanism 30 may have another number of transverse rod 320, which may be arranged parallel to each other or at an angle.
As shown in
The sliding sleeve 331 may be formed into a relatively flat and approximately hexahedral shape, which is convenient to be held and operated by hand. There may be two unlock buttons 332, which are respectively disposed on both sides of the sliding sleeve 331, and are convenient to be actuated by fingers (such as a thumb and a forefinger) pressing inward (toward the transverse rod 320). The two unlock buttons 332 can achieve more stable fixation, and may be symmetrically arranged. The number of unlock button 332 is not limited in the present application, that is, there may be another number of unlock button 332.
As shown in
The reset member 334 may be formed as an elastic element as shown in
In other embodiments, the reset member 334 may be formed as a spring disposed between the clamping portion 333 and an inner wall of the sliding sleeve 331. The reset member 334 may also be formed in another form as long as it can apply an inward pushing force on the clamping portion 333.
In other embodiments, the clamping assembly 330 may only have one unlock button 332 and one clamping portion 333. One, two or more reset members 334 may be provided as required.
A peripheral size of the clamping portion 333 may correspond to sizes of the folding fixing groove 321 and the unfolding fixing groove 322, so that the clamping portion 333 may exactly extend into and be held in the folding fixing groove 321 or the unfolding fixing groove 322. When the clamping portion 333 extends into the folding fixing groove 321 or the unfolding fixing groove 322, a gap between the clamping portion 333 and the folding fixing groove 321 or the unfolding fixing groove 322 is as small as possible, or the clamping portion 333 and the folding fixing groove 321 or the unfolding fixing groove 322 form a tight fit. Due to an elastic restoring force of the reset member 334, the sliding sleeve 331 will not slide easily, so that the crib frame 1 is more stable without shaking after being unfolded. More specifically, the unfolding fixing groove 322 is a through hole, and the clamping portion 333 is directly clamped into the through hole, which increases a cooperation area between the clamping portion 333 and the unfolding fixing groove 322, so that the sliding sleeve 331 and the transverse rod 320 may be fixed and limited more reliably, that is, the frame portion 10 and the supporting portion 20 will not shake relatively, so as to ensure the overall stability of the crib frame 1 after unfolding. Especially, under the action of the reset member 334, the clamping portion 333 is clamped into the through hole more deeply, the cooperation area is larger, the stability of the crib frame after unfolding is better, and the possibility of shaking of the crib frame is further reduced. Since a large locking force is not required when folded, the folding fixing groove 321 may be provided as a sinking groove, which ensures a better limitation and fixation to be formed between the clamping portion 333 and the folding fixing groove 321, so as to prevent the support portion 20 from falling after being folded, and at the same time, facilitates disengagement of the clamping portion 333 from the folding fixing groove 321, so as to facilitate unfolding of the supporting portion 20, that is, the unfolding and use of the crib frame 1.
The clamping portion 333 may be provided with a guiding portion 3332. The guiding portion 3332 may be a chamfer or a tapered surface or the like. The guiding portion 3332 may guide the clamping portion 333 into the folding fixing groove 321 and/or the unfolding fixing groove 322. With the help of the pushing force provided by the guiding portion 3332 and the reset member 334, the clamping portion 333 may automatically enter the folding fixing groove 321 or the unfolding fixing groove 322, or at least reduce a force required to further move the clamping assembly 330, when its guiding portion 332 contacts the folding fixing groove 321 or the unfolding fixing groove 322.

Optionally, the connecting rod 310 may only have the first connecting rod portion 313 or the second connecting rod portion 314.
The first connecting rod portion 313 and the second connecting rod portion 314 may be formed in a bent shape and mirror-symmetrical with each other. Optionally, the first connecting rod portion 313 and the second connecting rod portion 314 may be asymmetrical with each other. The bent shape may make the connecting rod 310 occupy less space under the frame portion 10, and at the same time, it may keep the supporting portion 20 stable relative to the frame portion 10.
A bending angle formed by the first connecting rod portion 313 and the second connecting rod portion 314 may be greater than 90 degrees. The bending angle formed by the first connecting rod portion 313 and the second connecting rod portion 314 may be less than 180 degrees. A bending portion formed by the first connecting rod portion 313 and the second connecting rod portion 314 may be a gentle transition.

In another embodiment (not shown), the upper recess 323 and the lower recess 324 may be formed on the elastic deformation portion 336, and the upper projection 337 and the lower projection 338 may be formed on the transverse rod 320. That is, the upper recess 323 and the lower recess 324, and the upper projection 337 and the lower projection 338 in this embodiment are just interchanged with each other with respect to those in the previous embodiment.
It should be understood that the recesses 323, 324 and projections 337, 338 on the transverse rod 320 and the elastic deformable portion 336 may prompt positions of the folding fixing groove 321, the unfolding fixing groove 322 or another fixing groove, so that an operator may still conveniently determine the positions of the folding fixing groove 321, the unfolding fixing groove 322 or another fixing groove even if these positions cannot be directly observed by the operator. The positions of the projections 337 and 338 and the recesses 323 and 324 may be interchanged with each other.
