Brake unit for baby stroller

Baby carriage brake control structure

The scope covered by this creation is a baby carriage brake control structure, especially the brake control structure is installed at the position of the push rod to facilitate the operator.

Generally, strollers carrying infants usually have a pushable handlebar, wherein the fixed handlebar is attached to the rear of the stroller frame seat part for the user to stand behind the stroller frame to push the stroller; In addition, a brake device is provided under the rear leg tube, that is, under the handlebar, to control the walking and parking of the stroller; generally, when using the stroller, the operator's foot pedal is mainly used to control the stroller's brake device; However, because the brake device is located at the end of the rear leg, and its position is usually hidden by other components, such as a food basket and a slanted backrest, the operator cannot accurately step on the brake structure when using it, or it is difficult to visualize it. It is quite inconvenient to use to confirm whether the car is braked or not.

In order to solve the above-mentioned lack of the conventional brake control device of the traditional baby stroller at the end of the rear leg, and the operators foot pedals to operate the brake device, this creation is to install the brake control structure on the push rod and connect it to the brake device. They are connected by a linkage, so that the operator can directly control the brake with their hands; the brake control structure is composed of a base, a housing, an operating rod, and a holder, wherein the operating rod can be operated The braking device forms a braking state, and the operating lever is clamped by the retaining member to keep the braking device in the braking state. The retaining member can also release the operating lever to return to the original position to form the braking state, thereby achieving convenient operation The effect of the operator.

The other purpose of this creation and the scope of further application can be clearly understood from the following detailed description. However, these detailed descriptions and the mentioned embodiments are for illustrative purposes only, because the various changes and amendments made in the spirit and scope of this creation are sufficient for professionals in this industry to learn from these detailed descriptions. It is clearly known from the description and drawings, but these detailed descriptions and drawings are for illustrative purposes only, and should not be limited to this creation. The description is as follows:

First, please refer to the second embodiment of the stroller brake control structure shown in FIG.

Please refer to Figures 2 to 4, the brake control structure 2 is connected with a brake device 3 and a linkage 4. The brake device 3 is installed between the lower end of the foot tube 12 behind the baby carriage frame 10 and the wheel set 13, and is used to lock the wheel set 13 to form a braking state, and can release the lock on the wheel set to make the brake state The wheel 13 can resume rotation.

The linkage 4 is connected between the braking device 3 and the brake control structure 2. In this embodiment, the linkage 4 is a flexible wire body.

The brake control structure 2 is installed on the push rod 11 provided with a long slot 111, and is composed of a base 21, a housing 22, an operating rod 23, a holder 24, a connecting rod 25 and an elastic element 26; The base 21 is a fixed device on the hand push rod 11 and has a long slot 211 opposite to the long slot 111 of the hand push rod 11.

Housing 22: is connected to the base 21. The housing 22 includes a receiving groove 221 capable of accommodating the movement of the operating rod 23, a receiving groove 222 capable of accommodating a holder, and a pivoting portion 223.

The connecting rod 25 penetrates the long slot 111 of the push rod 11 and the long slot 211 of the base 21. The connecting rod 25 is connected to one end of the link 4 so that the connecting rod 25 is in the slot 111 of the long slot. Pull the linkage 4 within the range to drive the braking device 3.

The operating rod 23 is pivotally connected to the base 21 and can be moved within the accommodating groove 221 of the housing 22. The operating rod 23 is in contact with both ends of the connecting rod 25 so that the operating rod 23 is moved , The connecting rod 25 must be pushed to move to drive the braking device 3 through the connecting member 4; the operating rod 23 further includes an operating portion 231 that can be pulled by the operator and a latching portion 232.

The holder 24 is pivotally connected to the pivot portion 223 of the casing 22 and placed in the receiving groove 222 of the casing 22, and an elastic element 26 is installed between the holder 24 and the base 21 or between the casing 22 , The holder 24 is reciprocally rotated. The holder 24 is located at the upper end position of the operating rod 23 and has a detent protrusion 241. The detent protrusion 241 can be used when the operating rod 23 moves to the upper end position. , It can form a latching position with the latching portion 232 of the operating rod 23 to keep the operating rod 23 at the upper end position. The operator can push the holder 24 to rotate, so that the operating rod 23 is separated from the latching protrusion 241 of the holder 24 And return to the lower end position.

With the above-mentioned components, when the brake device 3 is in the released state, the operating rod 23 is located at the lowermost position. When the operator wants to brake, the operating rod 23 is pulled, and the connecting rod 25 is pushed by the operating rod 23 through the linkage. 4. The braking device 3 is driven to restrict the rotation of the wheel set 13 to form a braking state. When the operating lever 23 is moved to the upper end position, the catch protrusion 241 is locked and positioned at the upper end position, so that the braking device 3 Keep the pair of wheels 13 in a braking state. When the operator wants to release the braking state, he pushes the retainer 24 to rotate, so that the locking projection 241 is separated from the locking portion 232 of the operating lever 23, so that the operating lever 23 returns to the lower end Position to release the restriction of the brake device 3 on the wheel set 13.

In summary, this creation has excellent practicability, novelty and advancement, and meets the requirements of a new patent application. The application is filed in accordance with the law. I implore the examiner to grant the patent as soon as possible.
