Description

Stroller that can be folded with one hand

The utility model relates to a baby carriage that can be folded with one hand, in particular to a device that can control the folding of the baby carriage with one hand.

Baby strollers are widely used. They can be used indoors for infants to ride or temporarily rest, and outdoors, they can be pushed by elders to walk around. One can reduce the fatigue of the elders when walking with them, and the two can make infants feel more comfortable. Comfortable activity space, so to provide a more practical stroller.

At present, there are many devices installed on the stroller, such as a brake device that can make the stroller stay in a suitable place, an orientation device that can control the steering of the wheels, a detachable and assembled armrest device, and a reversing device that can adjust the direction of the handle. The adjustment and positioning device that can adjust the inclination angle of the back pad, and the folding device that can make the entire stroller fold into a smaller state, the settings of each device can further improve the use efficiency of the stroller.

Among them, the design of the folding device can be seen in many types at present. For example, the creator of this article has designed the Taiwan Bulletin No. 248148 "Improved Stroller Folding Device (1)" and the Taiwan Bulletin No. 24 No. 8777 "Improved Stroller Folding Device (2)", these two structures are designed with the help of the locking devices on both sides. When folding, you only need to pull the locking devices on both sides upwards, that is The locking device can be detached from the positioning seat on the frame to achieve the purpose of completely retracting the frame. Because the above two structures emphasize the easy-to-pull structure, it is not only affirmed by the patent, but also very popular in the market. The reason The design of its entire structure is designed according to the needs of the user. After the user pulls up the latching devices on both sides with the control of both hands, each frame can be closed by the thrust due to interlocking, providing an easy-to-use Collapsed structure.

However, the above-mentioned folding devices must be controlled by both hands on the switch on both sides, or held at the handle with one hand, and the other hand is pulling the linkage rod to achieve the purpose of folding. Therefore, during use , which creates quite a few problems:

1. It is quite inconvenient to use: when the stroller you see so far is to be folded, you must use both hands to control the switches on both sides before the stroller can be folded, whether you pull the switches on both sides with both hands or hold it with one hand At the handle, the pull rod is designed with the other hand. If the user happens to use one hand or hold the baby, and there is no suitable place to place the object or the baby, the stroller can be folded with only one hand, which is equivalent. Difficult or even impossible to reach, causing considerable inconvenience.

2. Difficult to control: Due to the current folding structure, it is necessary to use both hands to control it. If the switch is turned on with both hands, or the pull rod is pulled with one hand, if the force applied on both sides is uneven due to improper force application, it will cause The switch on one side is not fully turned on. At this time, even if the frame is pressed down forcibly, the frame cannot be closed, and the switches on both sides must be pressed or pulled again with greater force to open. However, for users, there is already a problem of difficult control.

Therefore, the main purpose of this utility model is to provide a baby carriage that can be folded with one hand. The baby carriage is provided with a locking device on both sides between the handle bar and the front tilt bar, and a locking device is provided at the center of the handle. The click device has a turntable inside, each of the turntables is connected with the linkage piece of the click device with a flexible line, the linkage piece is fixed with the actuator seat of the click device, and the lower end of the turntable is set There is a toggle piece, and a control seat is provided on the turntable. The side of the control seat extends a protruding piece, which corresponds to the ring piece of the turntable. The cooperation between the lug piece and the ring piece, if the control seat is not pressed down When the push button is pressed, the turntable cannot rotate. When you want to close the stroller, you can press down the control seat with the palm of your hand to make the protrusion shift, and then pull the toggle piece up with your fingers to make the turntable Rotate according to the center point, and the synchronous flexible wires on both sides can pull up the connecting piece and the actuator seat. At this time, the force of pushing down the handle can be added to make each frame fold, because The design of the turntable can achieve the purpose of linkage, the design of one-hand control can achieve the purpose of easy operation, and the design of two-stage switch can achieve the purpose of safety, and provide a combination of linkage, easy operation and safety. stroller.

In order to achieve the above object, the utility model provides a baby carriage that can be folded with one hand. There is a locking device between them. The locking device is composed of an actuating seat that can move up and down and a fixed positioning seat. The separation and closing of the actuating seat and the positioning seat make the baby carriage in a folded or unfolded state. It is characterized in that: there is a push device at the center of the handle bar, the push device can drive the actuator seat of the latch device on both sides with a flexible wire, and when it is to be folded, the push device can be controlled so that the actuator seat and the latch device The positioning seat is separated to achieve the purpose of folding.

The above-mentioned stroller that can be folded with one hand is characterized in that the push device is composed of a front cover and a rear cover, and a turntable integrated with the handle bar is arranged inside, and a toggle plate is formed at the lower end of the turntable, and the two corresponding Flexible lines are fixed at each place, a ring is provided at an appropriate place on the periphery, and a control seat is fixed at an appropriate place on the handle bar. A reed is provided between the control seat and the handle bar. If the control seat is pressed down, the swivel can be driven to rotate by the toggle piece, and the flexible wires on both sides can be pulled simultaneously.

The aforementioned stroller that can be folded with one hand is characterized in that the flexible wire can be located inside the handlebar and connected to a linking piece, and the linking piece and the actuator seat of the locking device are fixed in one body to achieve linked movement. the goal of.

The biggest feature of this utility model is to provide a structure that can fold the whole stroller with only one hand. The utility model can make the stroller foldable with one hand through the cooperation of the push device and the catch device. combined action, and in terms of the overall structure of the utility model, it has the following effects:

1. Ease of operation: The utility model is designed in conjunction with the push device and the catch device, so that the user can perform the folding action with only one hand. For the user, it can avoid the difficult operation with one hand to provide an easy-to-operate structure.

2. The linkage relationship is reliable: the design of the utility model is that the flexible wires on both sides are driven by the turntable. The stroller can be easily folded away.

3. Safety: The button device of this utility model is a two-stage design. The control seat must be pushed down to make the turntable rotate, so it can avoid accidents caused by sudden external force applied to the toggle piece. , and provide a structure with a considerable safety effect.

Below in conjunction with accompanying drawing, further illustrate the specific structure feature and purpose of the present utility model.
