Description

269646 IX. Description of the Invention: [Technical Field] The present invention relates to a child care appliance, and more particularly to a toddler and a dining chair dual-purpose vehicle having both a toddler and a meal function. [Prior Art] During the learning walk of the child's growth process, the walker is usually used to help the child feel the leg strength and get used to walking. Referring to Fig. 1, a walker 2 of the novel "No. 190172" "Children's Walker Positioning Device" patent created by the inventor has a central hollowed-out chassis 21, and a plurality of peripheral edges along the bottom surface 211 of the chassis 21 are spaced apart. The roller 22 is disposed, and the plurality of rollers 22 are pivotally disposed on the foot of the chassis 23, a front frame that is pivotably pivoted to the chassis 21, and a front axle And a rear plate 26 pivotally disposed on the bottom plate of the chassis 2, a set of top plates 26 which are sighed at the top of the rear frame 24, 25 and provided with a receiving groove 261, and can be placed in the receiving portion Seat 27 of slot 261. The front frame is slidable with the rear frame 25 in a retracted position relative to the chassis 21 and a deployed position, and the pedals 23 are movable relative to the chassis 21 to a collection. Position and a stand up position. If the front and rear frames 24, 25 of the walker 2 are first used to the position of the open position, and the stand 23 is placed in the storage position, the child riding the mouth of the child is only required When the foot is on the ground, the roller can be used to move around. § To prevent the child from moving with the walker 2, the chassis (four) will be read as long as the frame is moved to the selected position. And the roller 22 is suspended, thereby achieving the purpose of positioning the walker 2 to move 1269646. If the walker 2 is to be returned to the state where it can be moved around, The tripod 23 is then moved toward the stowage 21 to the stowed position to restore the walker 2 to an active state. When not in use, the front and rear frame 24, 25 are first pushed to swing from the deployed position toward the chassis 21 to be in the folded position, and the top plate 26 is also interlocked and leans toward the chassis. 21 close. Although the patent case has the function of both toddler and safety positioning, there are still some points that can be improved: First, for convenience, the baby rice will be fed directly on the walker 2 'but because of 4 The walker 2 has a low height, and the eater must squat to be proud of it's still inconvenient in use. 'The height is lower than the table, and the special dining chair is required, which has the disadvantage of being expensive. When it is necessary to raise the habit of eating children at the table, the walker 2 needs to hold the child away from the walker 2, and it is relatively inconvenient to prepare the young child and need to purchase the dining chair. Content] is to provide a toddler with a walker and therefore, the purpose of the present invention is relatively convenient to use and avoid waste.

Further, the legs 32 are directed toward the 12 l269646 chassis seat 30 and are located at the storage position. As shown in FIG. 6, when the preferred embodiment is to be used as a toddler, the front and rear of the second front and rear frame 532, 531 are first pulled 536, 534, and the two front side bars 535 and the second The rear side bars 533 will oscillate in a direction away from the chassis seat 30 and interlock with the second sliding sleeve 523 to slide in the direction of the frame 521 to approach the second front mast 532. , until the top of the hoist, 53 is located in the second unfolding position, and the top plate unit ^ is also supported by the second and the second 牟ς〇 牟ς〇 1 枰 枰 532 532, 531 in the chassis seat 3〇=Up, at this time, the front link 536 is abutted against the disk body & the positioning can be obtained and the legs 32 are all (4) in the pure position, so that the child can ride The rollers 31 move along the ground 9 to move the steps.

Referring to FIG. 4, FIG. 5 and FIG. 6, the preferred embodiment is to be used as a dining chair, and the movable cover portions 7ΐ2 and Η] of the front and rear fixing members 71 and 72 are first turned toward the pass-through unit 711. The direction of the 721 is opened to release the frame cut, and then the frame 521 is pulled away from the remote chassis seat 3, and the first front and rear frame 512, 511 of the link unit 51 can be linked to each other. Moving away from the direction of the & disk holder 30, the two rear side bars of the first rear bar frame 5 ι=3 will interlock the first sliding sleeve 522 to slide along the frame 521 toward the first front bar 512. The two front side bars 515 of the first front mast 512 will also rotate the slider 41 and move along the sliding slot 336 from the folding end 337 to the limiting end 338 and be restrained by the positioning member 42. Being fixed at the limiting end 33^' II, the lower link unit .51 is supported on the chassis seat and positioned in the first deployed position, and the legs are further away from the The direction of the chassis seat 3〇 is moved to the supporting position, so that the rollers 3; 13 1269646 are held away from the ground 9 and the preferred embodiment can be fixed to the ground 9 for convenience. Fresh young children 'Finally, the frame 521 is mounted at the pedal foot placement for children 8, Beijing particular purpose may be formed as shown in the state 5 and an infant is seated T easy meal. Referring to FIG. 6 , FIG. 8 and FIG. 9 , the clamping body 422 of the positioning component 42 is firstly pulled to drive the base body 421 away from the limiting end 338 of the sliding slot 336 and the fastening portion 427 is to be folded. The card is placed in the locking portion 339, so that the sliding member 41 which is originally secured is movably removed from the limiting end and can be slid in the sliding slot 336 again when the sliding member 41 moves to the receiving portion. When the end 337 is closed, the second side rod 515 moves with the two movable members 41 and interlocks the rear side rod 513 to swing toward each other in the direction of the chassis seat 3 并 and drives the two first sliders 522 along the same. The frame 521 is slid away from the first front frame 512, so that the first rear frame 511 and the first front frame 512 can be swung to the first folding position, thereby driving the The frame 521 abuts against the chassis seat 3 and abuts against the bearing portions 711 and 721 of the front and rear fixing members π, and then the two movable cover portions 712 and 722 are fastened, and the frame 521 can be positioned at The chassis base 3 is formed in a state as shown in FIG. Then, the front link 536 of the second front frame 532 that is abutted against the disk body 61 is removed, and the two front side bars 535 and the two rear side bars are interlocked toward each other toward the chassis seat 30. The direction of the swing and drive the two second sliders 523 the stone frame 521 to slide away from the second front frame 532, so that the first rear bar 531 and the second front frame 532 are from the first The two deployed positions are swung to the second folding position, thereby driving the top plate unit 6 to lean toward 14 1269646 = the chassis seat 3G is folded. Finally, the legs 32 are all moved toward the chassis seat 3 to the collection. The position can complete all the folding actions and form a state of complete folding as shown in FIG. 2. Referring to FIG. 9 , it is worth noting that the fastening portion 427 of the positioning member 42 is released from the fastening portion 339 to automatically push the base body 421 back to the j by using the elastic restoring force of the elastic body 424. The position of the limit end 338 of the chute 336 is not adjacent to the position of k, (10) π%, and the body 422 is also pulled.
