The wheel carrier 41 includes a pair of spaced apart wheel plates 411 for rotatable coupling with the wheel 42, and is formed with a and that has a top open end 412 (see Figure 10), and a horizontally extending guiding groove 415 that extends transverse to the post hole 413, that is in spatial communication with the post hole 413, that is disposed at one side of the post hole 413, and that has a lateral open end 414. In this embodiment, a part of the guiding groove 415 overlaps the post hole 413, and the guiding groove 415 has a groove-defining wall formed with a first guiding slot 416 adjacent to the open end 414 and a second guiding slot 417 disposed 41 further has a first positioning rib 418 disposed in the guiding groove 415 Opposite to the open end 414.
The wheel coupling unit 5 includes a coupling post 51, a guiding and positioning component 52, a biasing member 53, and a limiting member 54.
The coupling post 51 has an upper section inserted 320 of the positioning member 32 of the fixing seat 3, and a lower section extended into the post hole 413. A rivet 60 is used to fix the upper section of the coupling post 51 and the upper end 322 of the tubular 31 of the fixing seat 3.
The guiding and positioning component 52 is coupled tothelowersectionof.thecoupljngpostsl, isdisposed in the post hole 413, and is formed with an inclined guiding surface 521 at a top side thereof. In this embodiment, the guiding and positioning component 52 includes a hollow tube sleeved on the lower section of the coupling post 51 and retained thereat by a rivet 61 such that the inclined guiding surface 521 faces in the front direction. In addition, the inclined guiding surface 521 is an oblique oval in shape.
The limiting member 54 includes a generally rectangular main body 541 extended into the guiding groove 415, a press part 542 extending from one end of the main body 541 and outwardly through the open end414 of theguidinggroove 415, acrossshapedsecond posit ioning rib 544 formed at an opposite end of the main body 541 and aligned with the first positioning rib 418, a protrusion 543 disposed on the main body 54]. proximate to the second positioning rib 544, a resilient arm 545 extending from the press part 542 toward the protrusion 543, a first hook part 546 extending from the distal end of the resilient arm 545 and located together with the protrusion 543 on the same side of the main body 541, and extending into and movable along the first guiding slot 416, and a second hook part 547 extending from another side of the main body 541 opposite to the first hook part 546 slot 417. It is noted that the first hook part 546 and the protrusion 543 may be located on different sides of the main body 541 in other embodiments of this invention. The first and second hook parts 546, 547 serve to retain movably the limiting member 54 in the guiding groove 415. In this embodiment, the protrusion 543 has opposite first and second lateral sides549, SSOthatarerespectivelydjspo$edproxjmate to and distal from the second positioning rib 544, and an inclined contact surface 548 that interconnects the first and second lateral sides 549, 550 and that surface 521 of the guiding and Positioning component 52.
The biasing member 53 is disposed in the guiding groove 415 and has Opposite ends mounted respectively on the first and second positioning ribs 418, 544.
The biasing member 53 biases the limiting member 54 toalockingpositjon, wheretheprotrusjon543exteflds into the post hole 413.
To mount the wheel unit 4 to the fixing seat 3, a force is first applied to the press part 542 to move the limiting member 54 to a releasing position, where the protrusion 543 ceases to extend into the post hole 413. Next, the lower section of the coupling post 51 together with the guiding and positioning component 52 is extended into the post hole 413 via the open end 412 until the disc portion 321 of the positioning member 32 is disposed adjacent to the top end of the wheel carrier 41 (see Figure 10) . When the press part 542 is subsequently released, the restoring force of the biasing member 53 drives the limiting member 54 to the locking position, where the protrusion 543 extends into the post hole 413 and is disposed between the guiding and positioning component 52 and the lower end323ofthetubularportjofl32Oiethepti 543 blocks the guiding and Positioning component 52.
The wheel unit 4 is mounted to the fixing seat 3 at this time and is capable of rotating about the coupling post 51 for 360 degrees when the caster 300 is placed on the ground. Moreover, since the protrusion 543 of the limiting member 54 blocks the guiding and positioning component 52, the wheel unit 4 cannot be removed from the fixing seat 3 at this time.
As shown in Figures 11, 12 and l3,to remove the wheel unit 4 from the fixing seat 3, a force is applied to the press part 542 in a direction (I) as best shown in Figure 12, so that the first and second hook parts 546, 547 move along the first and second guiding slots 416, 417 and so that the limiting member 54 is moved to the releasing position, where the protrusion 543 ceases to extend into the post hole 413 and ceases to block the guiding and positioning component 52.
Atthistime, thewheeJ.unjt4canbepulledjfladjrectjon (II) as best shown in Figure 13 for removal from the fixing seat 3.
As shown in Figures 14 and 15, when folding the carriage frame 2, the wheel unit 4 is suspended above theground, andthe protrusion S43iscapableof sliding along the inclined guiding surface 521 of the guiding and positioning component 52 from a first (highest) contact position toa second (lowest) contactposjtion on the inclined guiding surface 521 by virtue of weight of the wheel unit 4, thereby resulting in rotation of the wheel unit 4 relative to fixing seat 3 to a storage position, where the wheel unit 4 faces the front direction. In this embodiment, the protrusion 543 abuts against a top end of the inclined guiding andagainst a bottom end of the inclined guiding surface 521 when at the second (lowest) contact position defined on the inclined guiding surface 521, which corresponds to the storage position. Preferably, the inclined contact surface 548 of the protrusion 543 matches the inclined guiding surface 52]. when the protrusion 543 is at the second (lowest) contact position.
In particular, once suspended above the ground, the wheel unit 4 rotates in a first direction (V) as best shown in Figure 15 when the first lateral side 549 of the contact surface 548 of the protrusion 543 slides downwardly along the inclined guiding surface 521, and in a second direction (VI) opposite to the first direction as best shown in Figure 15 when the second lateral side 550 of the contact surface 548 of the protrusion 543 slides downwardly along the inclined guiding surface 521. As shown in Figure 15, in this embodiment, when the inclined contact surface 548 of theprotrusion 543 slides to thesecond (lowest) contact position on the inclined guiding surface 521, the direction of the wheel unit 4 is consistent with the inclined guiding surface 521 in facing the front direction (i.e., the storage position), and the wheel carrier 41 of the wheel unit 4 is spaced apart from the disc portion 321 of the Positioning member 32.
In this position, the wheel unit 4 will not interfere In practice, the presence of the inclined contact surface 548 on the protrusion 543 is optional since automatic rotation of the wheel unit 4 to the storage position by virtue of the weight thereof is still possible even without the inclined contact surface 548.
In summary, the caster 300 of this invention is
provided with the limiting member 54 and the guiding the wheel unit 4 to the storage position when the latter is suspended above the ground to facilitate folding of the baby carriage, and that cooperate to position the wheel unit 4 on the baby carriage. Moreover, the limiting member 54 is movable between the locking and releasing positions relative to the guiding and positioning component 52, thereby facilitating mounting and removal of the wheel unit 4 to and from the fixing seat 3.
