A top frame unit of a baby crib includes a plurality of three-way couplers and a plurality of top frame rods. Each coupler includes a root part and first, second and third tube parts that extend in different directions from the root part. The root part is formed with a cap-receiving recess that is in spatial communication with the first tube part. Each top frame rod includes a rod body that has opposite first and second rod ends, and an anchor cap that is mounted on the first rod end of the rod body. Each top frame rod is extended removably through the first tube part of one of the couplers such that the anchor cap thereof is disposed removably in the cap-receiving recess, and such that the second rod end of the rod body is extendible removably into the second tube part of another one of the couplers.

We claim: 1. A baby crib comprising: a bottom frame unit; a top frame unit; and a plurality of support rods that interconnect said bottom frame unit and said top frame unit, wherein said top frame unit includes: a plurality of three-way couplers, each of which including a root part and first, secon
We claim: 1. A baby crib comprising: a bottom frame unit; a top frame unit; and a plurality of support rods that interconnect said bottom frame unit and said top frame unit, wherein said top frame unit includes: a plurality of three-way couplers, each of which including a root part and first, second and third tube parts that extend in different directions from said root part, said root part including a thread-less cap-receiving recess hole through said first tube part, said third tube part being sleeved on a respective one of said support rods; and a plurality of top frame rods, each of which includes a rod body that has opposite first and second rod ends, and a thread-less anchor cap mounted on said first rod end of said body and shaped to engage said cap-receiving recess hole without protruding from said root part, wherein a first top frame rod is configured to extend removably through said first tube part and said cap-receiving recess hole of a first coupler such that said anchor cap of the first top frame rod is disposed removably in said cap-receiving recess hole of said first coupler without protruding from said root part of said first coupler, wherein a second top frame rod is configured to extend removably through said first tube part and said cap-receiving recess hole of a second coupler such that said anchor cap of the second top frame rod is disposed removably in said cap-receiving recess hole of said second coupler without protruding from said root part of said second coupler, and wherein said plurality of three-way couplers comprises at least three identical three-way couplers. 2. The baby crib as claimed in claim 1, wherein said bottom frame unit is foldable and is operable so as to bring said support rods close to each other when said top frame rods are removed from said couplers. 3. The baby crib as claimed in claim 1, wherein said rod body of each of said top frame rods is a tubular body. 4. The baby crib as claimed in claim 3, wherein each of said top frame rods further includes a positioning unit for retaining releasably said rod body on said first tube part of said one of said couplers. 5. The baby crib as claimed in claim 4, wherein said rod body of each of said top frame rods is formed with a radial hole that is spaced apart from said anchor cap, said positioning unit including: a U-shaped resilient arm disposed in said rod body; and a stop button mounted on one end of said resilient arm and extending through said radial hole in said rod body to arrest undesired removal of said rod body from said first tube part of said one of said couplers. 6. The baby crib as claimed in claim 1, wherein said rod body of each of said top frame rods includes first and second tubular parts that are interconnected removably and that are provided respectively with said first and second rod ends. 7. The baby crib as claimed in claim 6, wherein each of said top frame rods further includes a coupling unit for interconnecting releasably said first and second tubular parts of said rod body. 8. The baby crib as claimed in claim 7, wherein: said second tubular part has an end segment inserted removably into said first tubular part and formed with a first radial hole; said first tubular part is formed with a second radial hole to be aligned with said first radial hole in said second tubular part; and said coupling unit includes: a U-shaped resilient arm disposed in said end segment of said second tubular part, and a coupling button mounted on one end of said resilient arm and extending through said first radial hole in said second tubular part and into said second radial hole in said first tubular part. 9. The baby crib as claimed in claim 1, wherein each of said anchor caps is configured to engage a respective one of said cap-receiving recess holes non-rotatably. 10. The baby crib as claimed in claim 1, wherein cap-receiving recess holes correspond in shape to said anchor caps. 11. A top frame unit adapted for connection to a plurality of support rods of a baby crib, said top frame unit comprising: a plurality of three-way couplers, each of which includes a root part and first, second and third tube parts that extend in different directions from said root part, said root part including a thread-less cap-receiving recess hole through said first tube part, said third tube part being adapted to be sleeved on a respective one of the support rods; and a plurality of top frame rods, each of which includes a rod body that has opposite first and second rod ends, and a thread-less anchor cap mounted on said first rod end of said rod body and shaped to engage said cap-receiving recess hole without protruding from said root part, wherein a first top frame rod is configured to extend removably through said first tube part and said cap-receiving recess hole of a first coupler such that said anchor cap of the first top frame rod is disposed removably in said cap-receiving recess hole of said first coupler without protruding from said root part of said first coupler, wherein a second top frame rod is configured to extend removably through said first tube part and said cap-receiving recess hole of a second coupler such that said anchor cap of the second top frame rod is disposed removably in said cap-receiving recess hole of said second coupler without protruding from said root part of said second coupler, and wherein said plurality of top frame rods comprises at least three identical top frame rods. 12. The top frame unit as claimed in claim 11, wherein said rod body of each of said top frame rods is a tubular body. 13. The top frame unit as claimed in claim 12, wherein each of said top frame rods further includes a positioning unit for retaining releasably said rod body on said first tube part of said one of said couplers. 14. The top frame unit as claimed in claim 13, wherein said rod body of each of said top frame rods is formed with a radial hole that is spaced apart from said anchor cap, said positioning unit including: a U-shaped resilient arm disposed in said rod body; and a stop button mounted on one end of said resilient arm and extending through said radial hole in said rod body to arrest undesired removal of said rod body from said first tube part of said one of said couplers. 15. The top frame unit as claimed in claim 11, wherein said rod body of each of said top frame rods includes first and second tubular parts that are interconnected removably and that are provided respectively with said first and second rod ends. 16. The top frame unit as claimed in claim 15, wherein each of said top frame rods further includes a coupling unit for interconnecting releasably said first and second tubular parts of said rod body. 17. The top frame unit as claimed in claim 16, wherein: said second tubular part has an end segment inserted removably into said first tubular part and formed with a first radial hole; said first tubular part is formed with a second radial hole to be aligned with said first radial hole in said second tubular part; and said coupling unit includes: a U-shaped resilient arm disposed in said end segment of said second tubular part, and a coupling button mounted on one end of said resilient arm and extending through said first radial hole in said second tubular part and into said second radial hole in said first tubular part.
