Detailed Description

Referring to fig. 1 to 4, fig. 1 is an external view of a foldable game bed 10 according to a first embodiment of the present invention in an unfolding mode, and fig. 2 to 4 are schematic views of a part of the foldable game bed 10 according to the first embodiment of the present invention in different operation stages. The foldable playard 10 may be combined with a fabric to form a closed space to provide a safe playing environment for infants. The collapsible play yard 10 may include a plurality of upright members 12, a plurality of cross braces 14, and a locking mechanism 16. Each upright member 12 may include a pole 18, a corner joint 20, and a slip joint 22. In the present invention, the corner joints 20 and the sliding joints 22 can be considered as part of the upright members 12, or can be considered as specific members independent of the upright members 12.

A corner fitting 20 may be provided at the top end of the rod 18. A slip joint 22 is movably disposed on the rod 18. Each of the cross braces 14 may include an inner bar 24 and an outer bar 26. The inside rods 24 and the outside rods 26 are interleaved with each other and rotatably connected between two adjacent upright rods 12 using the corner joints 20 and the sliding joints 22. The collapsible play yard 10 is switchable between an expanded mode and a parallel mode (i.e., a collapsed mode). The folding play yard 10 switched to the parallel mode is referred to later fig. 24. As shown in FIG. 1, if the sliding joint 22 slides upward to approach the corner joint 20, the inner bar 24 and the outer bar 26 form an intersecting X-shape, and the foldable play yard 10 is positioned in the unfolded mode to provide a safe play space. If the sliding joint 22 slides downward relative to the rod 18, the inner rod 24 rotates clockwise and the outer rod 26 rotates counterclockwise, so that the rod 18, the inner rod 24 and the outer rod 26 are adjusted to be close to parallel to each other, and the foldable game bed 10 is positioned in parallel mode.

As shown in fig. 2-4, the latch mechanism 16 may include a latch body 28, a latch 30, a release 32, and a guide 34. The latch body 28 may have first and second ends 281, 282 that are oppositely located. The first end 281 may be pivotally or fixedly disposed at the corner joint 20 of the upright member 12. In other possible variations, the first end 281 may alternatively be disposed at the upper end of the upright member 12, such as the top of the rod 18, but the application is not limited thereto. The latch 30 may be disposed at the second end 282 and may removably engage or disengage the cross bracket 14 when the latch body 28 is compressed and flexed. For example, the latch body 28 may be bent in the first direction D1 to separate the latch 30 from the cross bracket 14, as shown in the latched phase of fig. 2 to the unlatched phase of fig. 3; alternatively, the latch body 28 may be flexed in the second direction D2 to engage the latch 30 with the cross brace 14, as shown in the unlatched stage of fig. 3 to the latched stage of fig. 2. The release latch 32 may be disposed at the second end 282 adjacent to the latch 30. When the release portion 32 is pressed by an external force, the latch main body 28 can be bent to disengage the latch portion 30 from the cross bracket 14. The guide 34 may connect the latch 30. The guide portion 34 slidably contacts the cross bracket 14 when the cross bracket 14 is slid upward relative to the upright member 12 by the sliding joint 22, and serves to guide the latch body 28 to be bent and deformed, so that the locking mechanism 16 locks the cross bracket 14.

In the first embodiment shown in fig. 2-4, the latch body 28 is a bendable latch member secured to the corner fitting 20. The latch body 28 is deformed and bent so that the engagement and disengagement of the latch portion 30 with the cross bracket 14 are performed. Further, the locking portion 30 may have an arc-shaped structure, and the size (e.g., arc) of the arc-shaped structure is adapted to the tube diameter (or arc) of the cross stent 14; in this way, the locking mechanism 16 can engage the cross bracket 14 in a tight fit and still allow for simple separation of the locking mechanism 16 and cross bracket 14 using the pressure release 32 and curved latch body 28. After the locking mechanism 16 is disengaged from the cross-shaped frame 14, the sliding joint 22 can slide down along the rod 18, so as to rotate the inner rod 24 and the outer rod 26 of the cross-shaped frame 14 to a nearly parallel position, and the foldable game bed 10 can be folded for storage. To open the foldable playard 10, the towing slider 22 slides the rods 18 upward, and the guide portion 34 guides the locking portion 30 of the locking mechanism 16 to lock the cross-shaped frame 14, thereby restricting the movement of the cross-shaped frame 14 relative to the upright member 12 and positioning the foldable playard 10 in the unfolding mode.

In particular, the present invention folding playard 10 does not have a separate upper armrest; the upper armrest refers to a bar member that is parallel to the ground when the foldable play yard 10 is in the unfolded mode for holding an infant. The present invention positions the cross brace 14 at the upper end of the upright members 12 so that the inner 24 and outer 26 side members of the cross brace 14 provide the armrest function.

Please refer to fig. 1, 5 and 6. Fig. 5 and 6 are schematic views of a part of a foldable game bed 10 according to a second embodiment of the present invention at different stages of operation. In the second embodiment, components having the same numbers as those in the first embodiment have the same structures and functions, and thus, description thereof will not be repeated. The second embodiment differs from the first embodiment in that the latch mechanism 16 of the second embodiment may include a latch 30' designed as a snap-fit structure and which will serve to support the bottom surface of the cross bracket 14. The taper below the snap feature of the second embodiment can be designed as a release 32 of the lock mechanism 16, while the side surface of the taper adjacent the cruciform baffle 14 can be designed as a guide 34 of the lock mechanism 16. The unfolding and folding processes of the folding game bed 10 of the second embodiment are similar to those of the folding game bed 10 of the first embodiment, and therefore, the description thereof will not be repeated.

Please refer to fig. 1, fig. 7, and fig. 8. Fig. 7 and 8 are schematic views of a partially collapsible play yard 10 according to a third embodiment of the present invention at different stages of operation. In the third embodiment, the components having the same numbers as those in the previous embodiments have the same structures and functions, and thus, the description thereof is not repeated. The locking mechanism 16 of the third embodiment does not clamp (i.e., the operational aspect of the first embodiment) or clasp (i.e., the operational aspect of the second embodiment) the crossing stent 14. The third embodiment differs from the previously disclosed embodiments in that the closure mechanism 16 of the third embodiment may include a closure 30 "having a first closure structure 36 and a cross-shaped stent 14 having a corresponding second closure structure 38. The first locking structure 36 releasably locks the second locking structure 38 to limit relative movement between the upright member 12 and the cross brace 14. The first locking structure 36 and the second locking structure 38 may be a slot and a post, respectively, that is inserted into the slot to limit movement between the locking mechanism 16 and the cross-shaped stent 14; the locking mechanism 16 is deformed by external force to disengage the post from the slot, allowing the cross-shaped bracket 14 to move freely relative to the upright member 12 and the locking mechanism 16. The actual configuration of the first locking structure 36 and the second locking structure 38 may vary according to design requirements, such as a cylindrical shape, an elliptic cylindrical shape, or a polygonal cylindrical shape, so that other possible embodiments are not listed. The unfolding and folding processes of the foldable game bed 10 of the third embodiment are similar to those of the foldable game bed 10 of the previous embodiment, and the description thereof will not be repeated.

Please refer to fig. 1 and fig. 9. Fig. 9 is a schematic view of a partially collapsible play yard 10 according to a fourth embodiment of the present invention. In the fourth embodiment, the components having the same numbers as those in the previous embodiments have similar structures and functions, and thus, the description thereof is not repeated. For example, the guiding portion 34 may have a guiding slope capable of slidably abutting against the cross bracket 14 to drive the latch body 28' to deform and bend, and the second locking structure 38 may be a protrusion for being inserted into a slot of the first locking structure 36. The difference between the fourth embodiment and the previously disclosed embodiment is that the locking mechanism 16 of the fourth embodiment may comprise a latch body 28' designed as a rotary latch member pivotally connected to the corner joint 20 of the upright member 12; in addition, the locking mechanism 16 may also include a locking portion 30A designed as a hook structure. The hook structure may have two sections that are connected in a bent manner, two opposite side surfaces of any rod of the cross-shaped bracket 14 are clamped by the two sections of the hook structure, and the bottom surface of any rod of the cross-shaped bracket 14 is supported by the connection place of the two sections of the hook structure. The latch body 28' is rotatable relative to the corner fitting 20 in either a clockwise direction R1 or a counterclockwise direction R2 so that the locking portion 30A can hook onto or disengage from the cross bracket 14, respectively, thereby limiting or allowing movement of the cross bracket 14 relative to the upright members 12. In the fourth embodiment, the latch body 28' preferably rotates in the clockwise direction R1; however, if there is sufficient clearance between the latch body 28 ' and the upright member 12 (e.g., changing the shape of the latch body 28 ' or the corner joint 20 or the sliding joint 22), the latch body 28 ' can also be rotated in the counterclockwise direction R2 to engage and disengage the locking portion 30A with and from the cross bracket 14. Furthermore, the present invention may optionally include a fastening element (e.g., a rivet, bolt, or screw) to connect the latch body 28 'to the corner fitting 20, such that the latch body 28' and the corner fitting 20 may have a corresponding clearance. The unfolding and folding processes of the foldable game bed 10 of the fourth embodiment are similar to those of the foldable game bed 10 of the previous embodiment, and the description thereof is not repeated.

Specifically, as shown in fig. 9, the locking mechanism 16 of the fourth embodiment can be selectively engaged with or disengaged from the cross-shaped bracket 14 by using slots and posts, as described in the third embodiment; however, the practical application is not limited thereto.

Please refer to fig. 10 to 13 and fig. 24. Fig. 10 is an external view of a foldable play yard 10 'according to a fifth embodiment of the present invention, fig. 11 is an exploded view of components of a part of the foldable play yard 10' according to the fifth embodiment of the present invention, fig. 12 and 13 are side views of the part of the foldable play yard 10 'according to the fifth embodiment of the present invention at different stages of operation, and fig. 24 is an external view of the foldable play yard 10' according to the fifth embodiment of the present invention in a parallel mode. In the fifth embodiment, the components having the same numbers as those in the previous embodiments have the same structures and functions, and thus, the description thereof will not be repeated. The collapsible playard 10 'may include a plurality of upright members 12, a plurality of cross braces 14, and a locking mechanism 16'. The locking mechanism 16' will be disposed in the rod staggering region of the cross stent 14. The thickness of the locking mechanism 16 'is preferably similar to the height of the overlapping inner bar 24 and outer bar 26 so that the folding playard 10' has a flat, aesthetically pleasing appearance in either the extended or parallel modes.

As shown in fig. 11-13, the locking mechanism 16' may include a first housing 40, a second housing 42, a locking transmission 44, and a resilient assembly 46. The first housing 40 may have a first engaging portion 48 and a first locking portion 50. The first engaging portion 48 can be a recessed structure formed on the side of the first housing 40 for engaging with the outer rod 26. The first locking portion 50 can be a slot structure formed inside the main body of the first casing 40, as shown in fig. 12 and 13, for locking the locking transmission member 44. The second housing 42 is rotatably coupled to the first housing 40 and has a second engaging portion 52 for engaging with the inner rod 24. The second engaging portion 52 may be a recessed structure formed on the side of the second housing 42, and may have a structure similar to the first engaging portion 48.

The lock drive 44 is movably disposed between the first housing 40 and the second housing 42. The locking transmission member 44 may have a second locking portion 54, and the second locking portion 54 is designed as a protruding structure to fit into the slot structure of the first locking portion 50. The inside lever 24 and the outside lever 26 may be disposed between the first housing 40 and the lock transmission 44. When the second locking portion 54 disengages the first locking portion 50 to allow relative rotation between the first housing 40 and the locking transmission 44, the inner link 24 can rotate relative to the outer link 26; when the second locking portion 54 is inserted into the first locking portion 50, the inner link 24 cannot rotate relative to the outer link 26. The resilient member 46 may be a compression spring disposed between the second housing 42 and the lock transmission 44. The elastic restoring force of the elastic component 46 can push the locking transmission piece 44 to move toward the first housing 40, so as to maintain the engagement between the first locking portion 50 and the second locking portion 54.

The locking mechanism 16' may have a release portion 56 movably disposed on the first housing 40; the projection 58 of the release portion 56 is detachably inserted into the broken hole 60 of the first housing 40. If the release latch 56 is moved into the recessed area of the first housing 40, the protrusion 58 can be inserted into the hole 60 to push the second locking portion 54 away from the first locking portion 50, so that the locking transmission member 44 can rotate relative to the first housing 40 to allow the inner bar 24 and the outer bar 26 to rotate relative to each other. If the external force applied to the releasing part 56 is removed, the elastic restoring force of the elastic component 46 pushes the locking transmission piece 44 to lock the second locking part 54 to the first locking part 50; in this way, the protrusion 58 can move out of the hole 60 to disengage the release latch 56 from the recessed area of the first housing 40.

When the first locking portion 50 and the second locking portion 54 are separated from each other, the inner rod 24 and the outer rod 26 can pivot with respect to each other about the assembly of the first housing 40 and the second housing 42, and the sliding joint 22 can slide downward, thereby preparing to fold or unfold the foldable game bed 10. If the sliding joint 22 slides upward to pivot the inner link 24 and the outer link 26, the second housing 42 and the locking transmission member 44 can rotate relative to the first housing 40; if the second locking portion 54 is aligned with the first locking portion 50, the elastic member 46 pushes the second locking portion 54 of the locking transmission member 44 to lock the first locking portion 50 of the first housing 40, so as to restrict the relative rotation between the inner bar 24 and the outer bar 26, and the foldable playard 10 can be positioned in the unfolding mode.

Please refer to fig. 14-17. Fig. 14 is an external view schematically showing a foldable play yard 10 "according to a sixth embodiment of the present invention, and fig. 15 to 17 are side views of a part of the foldable play yard 10" according to the sixth embodiment of the present invention at different stages of operation. In the sixth embodiment, the components having the same numbers as those in the embodiments disclosed above have the same structures and functions, and therefore, the description thereof will not be repeated. The collapsible playard 10 "may include a plurality of upright members 12, a plurality of cross braces 14, and a locking mechanism 16". The locking mechanism 16 "may be disposed at the junction of the cross bracket 14 and the slip joint 22.

As shown in fig. 15 and 16, the locking mechanism 16 "may include a latch body 62, an actuator 64, and a resilient member 66. The latch body 62 is movably disposed within the cross-shaped support 14 and may generally be disposed within the stem of the cross-shaped support 14, although practice is not limited thereto. An actuator 64 may be connected to the latch body 62 and slidably disposed in the cross bracket 14. The latch body 62 is pulled to perform a synchronous action when the actuating member 64 is pushed to move relative to the rod of the cross type bracket 14 by the external force of the user or the elastic restoring force of the elastic member 66. The resilient assembly 66 may be disposed between the cross bracket 14 and the latch body 62. A slot 68 may be formed on the rod 18 of the upright member 12, and the elastic restoring force of the elastic element 66 may push the latch body 62 to engage with the slot 68. The actuator 64 is forced to move backward relative to the lever 18, so as to disengage the latch body 62 from the slot 68 of the lever 18 and compress the elastic member 66 to store elastic restoring force. In this manner, the cross stand 14 can be rotated relative to the upright member 12 to stow the collapsible play yard 10 ".

As shown in fig. 16 and 17, the cross-shaped bracket 14 can be pivotally connected to the sliding joint 22 of the upright member 12 by a connecting shaft 70; the latch body 62 may have a track 72, and the track 72 slidably and rotatably engages the connecting shaft 70. The connection shaft 70 and track 72 combination allows the cross bracket 14 and locking mechanism 16 "to rotate relative to the slip joint 22 of the upright member 12. Thus, the latch body 62 may protrude out of the cross bracket 14 for insertion into the slot 68 of the pole 18 for limiting rotation between the upright pole 12 and the cross bracket 14 so that the folding play yard 10 "can be positioned in the deployed mode. If the latch body 62 is disengaged from the slot 68 and received within the cross bracket 14, the cross bracket 14 can be rotated relative to the upright member 12 to stow the collapsible play yard 10 ".

Referring to fig. 18 to 20, fig. 18 is an external view of a foldable game bed 10 "according to a seventh embodiment of the present invention, and fig. 19 and 20 are side views of a part of the foldable game bed 10" according to the seventh embodiment of the present invention at different operation stages. In the seventh embodiment, the components having the same numbers as those in the embodiments disclosed above have the same structures and functions, and therefore, the description thereof will not be repeated. The lock mechanism 16 "of the folding play yard 10" may be disposed at the connection area of the cross bracket 14 and the sliding joint 22, and the lock mechanism 16 "may include a latch body 74, a lock 76, and a release 78.

The latch body 74 may be disposed at the cross bracket 14 and rotatably engage the slip joint 22 of the upright member 12. The locking portion 76 may extend outwardly from the latch body 74, and the release portion 78 may be disposed at a front end of the locking portion 76.
