FIELD OF THE INVENTION The present invention relates to a reversible baby stroller with a brake structure.

c 5 More particularly, the present invention includes a handlebar having an actuated member.

00 0 O The scope of the present invention relates to a reversible baby stroller with a brake structure. The frame of the baby stroller has a reversible handlebar. Besides, the handlebar has an actuated member, and is connected between the actuated member and the brake mechanism through the flexible wire. Further, whether the handlebar is in the position of the front or the rear, the user can use the actuated member to control the brake mechanism.

BACKGROUND OF THE INVENTION The conventional baby stroller usually has a handlebar for the user to push. The fixed type handlebar is positioned behind the rear of the frame seat in the baby stroller, and is convenient for the user to push the baby stroller from the rear. Further, the rear legs having a brake apparatus, in other words said brake apparatus is positioned on the lower side of the handlebar, which can be controlled for movement and to stop the baby stroller.

Since the fixed type handlebar is pushed by the user from the rear of the seat, the baby cannot see the user and feels unsecure and unstable.

Besides, some baby strollers use the reversible handlebar. The handlebar is jointed on the frame, and selectively fixed by either face or back to the baby for further pushing the baby stroller. However, when the handlebar is changed to face the baby as a pushing position, the user is required to choose another side to operate the brake apparatus, and has more trouble in the operation. This is because the original brake apparatus is o positioned on the lower side of rear legs. In order to overcome the above problem, some

O

of the front wheel sets have the brake apparatus. However, this method is not only a waste, but also causes confusion and inconvenience to the user. Similarly, the user can M 5 not recognize which set has already been released or is in the brake status.

00oO SUMMARY OF THE INVENTION According to the above mentioned descriptions, the conventional reversible baby stroller with a brake structure has an inconvenient operation and expensive cost. The present invention related to a reversible baby stroller with a brake structure can overcome the above disadvantages. The handlebar in the present invention has an actuated member.

The flexible wire is connected between the actuated member and either front or rear brake mechanism, and said actuated member can control the brake mechanism as well as select the baby stroller in either movement or stop status. The actuated member and the flexible wire are both positioned on the handlebar. Therefore, the actuated member moves along the handlebar when the user changes the direction of the handlebar. Further, the user can operate the actuated member through the flexible wire to drive the brake mechanism as well as to achieve convenience.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Please refer to Figure 1 and Figure 2. The present invention relates to a reversible baby stroller with a brake structure. The present invention mainly provides that the user can change the direction of the handlebar 1 either in the front or in the rear of the baby stroller as well as control the same brake mechanism on the handlebar. The present invention comprises a frame of the baby stroller 10, a brake mechanism 2, and a driving mechanism 3.

The above mentioned frame 10 of the baby stroller consists of multiple tubes, and the wheel set 11 is joined with wheel 12 for movement. Besides, it also includes a seat portion 13 for baby to sit. Further, the frame of the baby stroller 10 includes a joint portion 14, a front positioning portion 15, a rear positioning portion 1 6 [Al, and a handlebar 1. Please refer to figure 5. The handlebar 1 has a reversible sleeve 17. The end is joined with the joint portion 14 of the frame 10 in the baby stroller. It can use the sleeve 17 on either the front portion 15 or the rear portion 16 to lock for positioning.

C-)

O Therefore, the handlebar 1 rotates and positions in either the front or the rear by the joint O portion 14. Further, it can provide the user to choose either face or back to the baby to push the baby stroller for convenience.

Cc 5 Please refer to Figure 3. The brake mechanism 2 is positioned on the wheel set 11 00 in the lower side of the frame 10 in the baby stroller, and can control the brake of the wheel 12. In the present preferred embodiment, the brake mechanism 2 includes a wheel base 21, a brakebar 22, and a slider 23. The slider 23 is inside the wheel base 21, and also can slide inside the wheel base 21. The brake rod 22 is penetrated through the slider 23, and moves along the slider 23. The position of the brakebar 22 is changed and forms a lock with the wheel 12, and can prevent the wheel 12 rotating. An elastic member 24 is positioned between the slider 23 and the wheel base 21. By using the electric member 24, the slider 23 and the brakebar 22 return to the released position which is not in contact with the wheel 12. Further, the brake mechanism 2 also can use the brake pad (not shown in the figure). The friction of the contact between the brake pad and wheel 12 makes the wheel speed down or stop.

Please refer to Figure 4. The brake apparatus 2 can be controlled by a driving apparatus 3. The driving apparatus 3 includes an actuated member 31 and a flexible wire 32. In the present preferred embodiment, the actuated member 31 is positioned on one side of the handlebar 1 as well as joined with the handlebar 1. The user can switch to either a positioning location 311 or a released location 312. Please refer to Figure 4. In the present preferred embodiment, the positioning location 311 in the actuated member 31 has a lock portion 8 The handlebar 1 has a positioning portion 9. When said actuated member 31 rotates to the positioning location 311, said lock portion 8 uses a spring 7 to push into the positioning portion 9 for said actuated member 31 to remain at O a positioning location 311. When the lock portion 8 is away from the positioning location

O

9, the actuated member 31 again returns to the released position 312.

Please refer to Figure 6. The above mentioned flexible wire 32 is positioned M, 5 between the actuated member 31 and the brake mechanism 2. In the present preferred 00oO embodiment, the flexible wire 32 is positioned on the inside of the handlebar 1. Further, both ends are individually connected between the actuated member 31 and the slider 23 N or the brake pad. The rotation of said actuated member 31 through the flexible wire 32 can drive the brakebar 22 to move. Further, the brakebar 22 can either limit the movement or releasethe wheel 12. In the present preferred embodiment, the flexible wire 32 is extended to the downside in the inside of the handlebar through the single side of the apparatus. Further, it is connected with a transferred junction 4, and said transferred junction 4 has two flexible branch wires 321 individually connecting with the brake mechanism 2 in both sides. Besides, the actuated member 31 also can be positioned in between the handlebar 1 (not shown in the figure). Further, both sides can extend the flexible wires 32, and said pair of flexible wires 32 are individually connected with the brake mechanism 2.

According to the above mentioned components, the user can select the handlebar 1 positioning either in the front portion 15 or in the rear portion 16 for either facing or backing the baby, and pushing the handlebar 1 to move the frame 10 of the baby stroller.

Since the actuated member 31 is positioned on the handlebar 1 and the flexible wire 32 is along the handlebar, the actuated member 31 and the flexible wire 32 move along the handlebar 1, but do not affect the brake function. When the user wants to brake, the actuated member 31 is first pulled. When the brakebar 22 or the brake pad are pulled c-i through the flexible wire 32, either said brakebar 22 or the brake pad makes the brake on o the wheel 12. The actuated member 31 is positioned in the positioning location 311 as well as being fixed, the brakebar 22 makes the wheel 22 remain in the brake status. For releasing, the actuated member 31 is also pulled to the released position 312. Further, the M 5 elastic member 24 assists the brakebar 22 or the brake pad to release the limitation on the 00oO wheel 12.

It will be appreciated that, although a specific embodiment of the invention has CI been described herein for purposes of illustration, various modifications may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not limited except as by the appended claims.
