A conventional rocking chair is often designed with a fixing structure which is not able to fold, so that the conventional rocking chair has a big size and cannot be stored easily.
Therefore, the conventional rocking chair has limitation of being used in a specific place. For example, it only can be placed inside a house and cannot be carried out with a user.
In order to improve this disadvantage, a foldable rocking chair is provided in the market. The foldable rocking chair can be folded or unfolded by a folding mechanism, so that the foldable rocking chair can be transported or stored easily.
However, the conventional folding mechanism has no design to prevent an error operation, so that the conventional folding mechanism may be activated to fold the foldable rocking chair accidentally. That is, there is a safety risk with the foldable rocking chair. As a result, it is an important issue to design a folding mechanism with a safety lock to prevent the foldable rocking chair from folding accidentally.

FIG.9 is a diagram illustrating that the rotary-type locking device 35 is in a locked state as the foldable rocking chair is in a folded state according to the embodiment of the present invention. FIG.1O is a diagram illustrating that the rotary-type looking device 35 is in an unlocked state according to the embodiment of the present invention. FIG.ll is a diagram illustrating that the rotary-type locking device is in the looked state according to the embodiment of the present invention. As shown in FIG.8, an engaging protrusion 322 for contacting the first engaging rib 353a or the second engaging rib 353b is formed on the second rotating base 32.

As ir is desired to unlock the rotary-type locking device 35, the rotary button 351 can be rotated to drive each driving column 351a to slide from the deep end 352b1 to the shallow end 352b2 of the corresponding inolined slot 352b. Because of interference of the driving column 351a and the inclined slot 352b, the driving component 352 overcomes a resilient force of the recovering component 354 to push the engaging component 353 to move into the third rotating base 33, so that the engaging protrusion 322 is separated from the first engaging rib 353a. As a result, the second rotating base 32 can rotate relative to the third rotating base 33, so as to implement an unlocking function of the rotary-type locking device 35, as shown in FIG.lO. As shown in FIG.l1, as the upper supporting tube 21 and the lower supporting tube 11 unfold to a maximum angle, the engaging protrusion 322 is spaced from the first engaging rib 353a, so that it only needs to operate the press-type locking device 34 to adjust the angle between the upper supporting tube 21 and the lower supporting tube 11. As the rotary button 351 keeps rotating, the first engaging rib 353a contacts the engaging protrusion 322 so as to implement a looking function. As it is desired to fold the foldable rocking chair completely, it has to unlock the rotary-type locking device 35.
Preferably, as shown in FIG.3, a hallow space is formed on the engaging component 353, and a restraining edge 353c is formed on an inner side of the engaging component 353 so as to divide the hallow space into a first containing space 353d and a second containing spaoe 353e.

As shown in FIG.5, at least one first rib portion 311 is formed on the first rotating base 31, and a side of each tooth 342a of the gear 342 is contacting against the at least one first rib portion 311. As shown in FIG.6, at least one second rib portion 333 is formed on the third rotating base 33, and the other side of each tooth 342a of the gear 342 is contacting against the at least one second rib portion 333. That is, the two sides of each tooth 342a contacts against the corresponding first rib portion 311 and the corresponding second rib portion 333 respectively. The at least one second rib portion 333 restrains the gear 342 from rotating relative to the third rotating base 33, so that the gear 342 only can move axially. The at least one first rib portion 311 contacts the corresponding tooth 342a in a detachable manner for restraining the first rotating base 31 from rotating relative to the third rotating base 33.
The recovery component 343 is disposed between the gear 342 and the third rotating base 33, and two ends of the recovery component 343 contact against the gear 342 and the third rotating base 33. The reccvery component 343 is fcr recovering the gear 342 to an initial position. The button 341 passes through the first rotating base 31 axially to contact the gear 342. As the press-type locking device 34 is desired to be unlocked, the button 341 is pressed to force the gear 342, so that the gear 342 overcomes a resilient force to be pushed into the third rotating base 33. As a result, the plurality of teeth 342a is separated from the first rib portion 311, so that the first rotating base 31 can rotate relative to the third rotating base 33 to adjust the angle between the lower supporting tube 11 and the upper supporting tube 21. The press-type locking device 34 can be unlocked with the rotary-type locking device 35 cooperatively to achieve a purpose of folding the foldable rocking chair.
Preferably, a first inclined surface 342al is formed on a side of each tooth 342a close to the first rotating base 31, and a second inclined surface 311a corresponding to the first inclined surface 342a is formed on the first rib portion 311. As the upper supporting tube 21 is desired to rotate relative to the lower supporting tube 11 to the maximum angle, the button 341 is pressed to force the gear 342, and the second inclined surface 3lla of the first rib portion 311 contacts against the first inclined surface 342a1 of the tooth 342a, so that the gear 342 overcomes the resilient force to be axially pushed into the third rotating base 33. As a result, the plurality of teeth 342a is separated from the first rib portion 311 of the first rotating base 31, so that the first rotating base 31 can rotate relative to the third rotating base 33.
Preferably, as shown in FIG.3, at least one pressing portion 341a is formed on the button 341 for passing through the first rotating base 31 and contacting the gear 342. A hock pcrtion 341a1 is disposed on an end of each pressing portion 341a, and the hock pcrtion 341a1 is used fcr contacting against an inner surface of the first rotating base 31 to prevent the button 341 from separating from the first rotating base 31 outwardly.
In contrast to the prior art, the foldable rocking chair of the present invention can be locked safely by cooperation of the press-type locking device and the rotary-type locking device, so that it is more effective to prevent the foldable rocking chair from folding accidentally than using only one lock mechanism. Iwo locking devices with different locking methods can effectively prevent a user from perfcrming an error operation, resulting in folding the foldable rocking chair accidentally. As a result, the present invention can achieve an effect of double protection.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
