DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Please referring to FIGS. 1, 2A and 2B, the present invention aims to provide a walk assisting apparatus 100 that integrates a walker and a walk assistant. It includes a first body 10, an elevated bracket 20 connected to the first body 10, a second body 30 connected to the elevated bracket 20 in a detachable manner, and a handgrip 40 connected to the second body 30 in a detachable manner. Through assembly of the first body 10, the elevated bracket 20 and the second body 30 the walk assisting apparatus 100 can be constructed to become a walker, or through assembly of the second body 30 and the handgrip 40 the walk assisting apparatus 100 can be constructed to become a walk assistant, thereby the walk assisting apparatus 100 can be changed in varying styles to aid children to learn walking at different growing stages.

[0031] More specifically, the first body 10 includes a plurality of first wheels 11 and a first frame 12 connected to the first wheels 11 and formed in an annular fashion. The first frame 12 is formed in a full annular shape to become a structure with greater strength to provide sufficient support power and safety for the children when in use. The elevated bracket 20 includes two bracing arms 21 and a loading tray 22 to bridge the bracing arms 21. Each bracing arm 21 has one end remote from the loading tray 22 with a confining sleeve 211 located thereon. The loading tray 22 has one end remote from the confining sleeve 211 with a latch slot 221 formed thereon. The elevated bracket 20 is foldable to facilitate storing and save storage space. The second body 30 includes a plurality of second wheels 31, a second frame 32 connected to the second wheels 31 and leaned on the loading tray 22 and the bracing arms 21, and two wedge holes 33 formed on the second frame 32.

[0032] Also referring to FIG. 3, in this embodiment the walk assisting apparatus 100a is formed in a walker with a center space to allow a child to extend the legs to the ground surface and exert forces on the ground surface to move the walk assisting apparatus 100a, thereby can train the child to walk by using the legs.

[0033] The second body 30 includes a housing space 50 to accommodate the child so that the child can be held in the housing space 50 to maneuver the walker to move. In this embodiment the walk assisting apparatus 100a is preferably to include a seat 60 in the housing space 50 to support the child before the child is not yet skillful in using the legs to exert the forces so that the child can extend the legs to the ground surface to slide the first wheels 11 in moving. Please referring to FIGS. 4A through 4D, the second frame 32 includes a latch element 321 latchable on the latch slot 221 and two confining blocks 322 that can be coupled respectively with the confining sleeve 211 (as shown in FIG. 2B). The latch element 321 includes a spring 3211 connected to the second frame 32 and extended in normal conditions, a handle 3212 connected to the spring 3211 and a locking block 3213 connected to the handle 3212 and pressed by the spring 3211 to lean on the latch slot 221. Referring to FIG. 4C, when the second body 30 and the elevated bracket 20 are coupled together the spring 3211 is extended to push the handle 3212 and position the locking block 3213 in the latch slot 221, then the second body 30 cannot be removed from the elevated bracket 20. Please referring to FIG. 4D, by drawing the handle 3212 to compress the spring 3211 the locking block 3213 can escape the latch slot 221, then the second body 30 can be removed from the elevated bracket 20. Through the aforesaid structure the first body 10, the elevated bracket 20 and the second body 30 can be easily assembled or detached. Also referring to FIGS. 3, 4A and 4E, furthermore, the seat 60 includes an inverse hook 61 corresponding to the loading tray 22 and two latch boards 62 at two sides of the seat 60. The second frame 32 includes an inclined slot 323 corresponding to the inverse hook 61 (also referring to FIG. 2A) and two latch blocks 324 corresponding to the latch boards 62. As shown in the drawings, each latch block 324 has a sloped surface 325, and each latch board 62 has a latch hole 63 latchable by each latch block 324. During installation of the seat 60 by inserting the inverse hook 61 into the inclined slot 323 (as shown in FIG. 4B) and push the seat 60 downward toward the first body 10, each latch board 62 can slide along the sloped surface 325 in a slightly bending manner, and when the latch hole 63 is corresponding to the latch block 324 the bending force of latch board 62 vanishes so that the latch block 324 can be wedged in the latch hole 63 to form latching, thereby installation can be accomplished simply and quickly.

[0034] Please referring to FIGS. 5, 6A and 6B, in this embodiment the walk assisting apparatus 100b is formed in a walk assistant to allow a child to grasp the handgrip 40 and move the walk assisting apparatus 100b. Such a style is suitable for the child with sufficient leg development and walk capability to train the balance sense of the child during walking.

[0035] More specifically, the handgrip 40 includes a handgrip bar 41 and two latch tenons 42 connected to two ends of the handgrip bar 41 corresponding to the wedge holes 33. In one embodiment each latch tenon 42 includes an eccentric anchor rib 43, and each wedge hole 33 is formed in an asymmetrical shape corresponding to the latch tenon 42 and the anchor rib 43 so that the latch tenon 42 and the wedge hole 33 can be coupled only in a specific direction to provide fool-proof function.

[0036] In addition, please referring to FIGS. 7A and 7B, in order to increase pleasure and motivation for the child to walk the walk assisting apparatus 100b can include an ornamental tray 70 with a plurality of ornaments 71 movable with the second wheels 31. The ornaments 71 can be figure toys in animal shapes or the like. The ornamental tray 70 and the second wheels 31 can be bridged by a transmission element such as a bevel gear (not shown in the drawings) to generate chain movements. When the child moves the walk assisting apparatus 100b the second wheels 31 rotate and drive the ornaments 71 on the ornamental tray 70 to rotate or move, thereby can motivate the child to practice walking.
