For dogs with various sizes, there are pet strollers of different sizes correspondingly, so as to have dogs of various sizes to rest in the pet strollers either sitting or lying down safely and steadily and provide them the most comfortable outing and walking circumstance.
Most large-sized pet dogs are the favor and priority of many pet owners because of their mild temper and stability. Relatively, walking large pet dogs requires larger pet strollers. Although the current large pet strollers available in the current market are feasible for large-sized pet dogs, these pet strollers become less feasible to those older medium and large-sized pet dogs since they become more difficulty to move and turn around in the pet strollers. As a result, it can often be found that old medium- and large-sized dogs have a hard time to enter their pet strollers, which leads to inconvenience to the pets and their owners.
Hence, there is a need in the market to create a more feasible pet stroller for older medium and large-sized pet dogs. It would be more convenience to the older medium and large-sized pet dogs if the canopy structure of the pet stroller is able to be rapidly transformed among a covering mode, a front opening mode, and a full-opening mode, so as to not only avoid the pet dogs from jumping out of the pet stroller, but also make it more convenient for pet dogs with difficulty of moving to hop on and off, that can improve the overall utility and convenience thereof.
An object of the present invention is to provide an adjustable supporting frame and canopy structure of a pet stroller that allows the pet stroller to be selectively transformed into a covering mode, a front opening mode, or a full-opening mode mainly by means of an adjustable supporting frame and an adjustable canopy, which is not only suitable for normal medium and large-sized dogs to use, but also more suitable for older medium and large-sized dogs with difficulty of moving to use, so as to enhance the overall utility and convenience of the pet stroller.
In order to achieve the above object, the present invention provides a pet stroller with an adjustable supporting frame and canopy structure, which comprises a pet stroller body, an adjustable supporting frame and an adjustable canopy. The pet stroller body has a frame shaped chassis rack.
The frame shaped chassis rack comprises a rear frame arranged on the back side thereof, a folding brace respectively diagonally arranged on the two sides of the frame shaped chassis rack and the rear frame, a stroller grip extendedly arranged on the top of the rear frame, a base plate arranged on the frame shaped chassis rack, two steering wheels respectively arranged on the two sides of the front end of the frame shaped chassis rack, and two wheels respectively arranged on the two sides of the back end thereof.
The adjustable supporting frame comprises two rotation shaft boxes respectively arranged on inner sides of the folding brace of the two sides of the pet stroller body. Each rotation shaft box is connected with the frame shaped chassis rack and the rear frame respectively through two props. The rotation shaft box comprises a canopy strut extended diagonally upwards from the front end thereof and a front window strut extended forward parallelly from the front end thereof. The front window strut has two sliding sleeves respectively arranged on the two sides thereof. Each sliding sleeve is connected to the frame shaped chassis rack through a prop.
The adjustable canopy covers on an external side of the pet stroller body and corresponds to the adjustable supporting frame, so as to allow the adjustable canopy to be switched among a covering mode, a front opening mode, and a full-opening mode through adjusting positions of the canopy strut and the front window strut.
In a preferred embodiment, when the adjustable canopy is in the covering mode, the canopy strut is extended diagonally forward and the front window strut is extended forward and parallel to the frame shaped chassis rack. When the adjustable canopy is in the front opening mode, the canopy strut is extended diagonally forward and the front window strut is upwardly turned and parallel to the canopy strut, so as to form an opening at the front of the adjustable canopy. When the adjustable canopy is in the full-opening mode, the canopy strut is backwardly turned and leant against the rotation shaft box and the front window strut is also backwardly turned and leant on the front side of the canopy strut, so as to allow the adjustable canopy to be opened from the front to the back.
