Abstract

A child stroller apparatus (100) includes a standing frame (102), a push handle frame (108) having a side segment (108A) pivotally connected with the standing frame (102) via a pivot connection (118), an adapter (132) configured to couple to a detachable part (202, 206) by engagement of the adapter (132) with the detachable part (202, 206), and a locking mechanism (170) for locking the adapter (132) in a desired position on the side segment (108A). The adapter (132) is fixedly connected with a handle (160) that is located behind the adapter (132) when the child stroller apparatus (100) is in an unfolded state for use so that the handle (160) is slidable along the side segment (108A) for adjustment between a lowest position in which the adapter (132) is adjacent to and at the same level as the pivot connection (118) and a plurality of upper positions in which the adapter (132) is spaced apart from and above the pivot connection (118). The locking mechanism (170) includes a latch (172) and a release actuator (174) respectively connected with the handle (160) to selectively lock the adapter (132) in a desired one of the lowest position and the upper positions.

Description

CROSS-REFERENCE TO RELATED APPLICATION(S) This application is a divisional application of EP patent application no. 19172563.9 filed on May 3, 2019, which respectively claims priority to US provisional application no. 62/666,326 filed on May 3, 2018, and to US provisional application no. 62/792,577 filed on January 15, 2019. BACKGROUND 1. Field of the Invention The present invention relates to child stroller apparatuses. 2. Description of the Related Art Caregivers usually rely on a stroller apparatus to transport babies and children. A stroller apparatus is typically constructed from a metal frame that comprises an assembly of metal and plastic parts, and a fabric element that connects or wraps around the metal frame. When it is unused, the stroller apparatus can be collapsed for convenient storage or transport. Some existing stroller apparatus may be configurable to include one or multiple seats so as to be able to transport one or more children at a time. However, a stroller apparatus accommodating multiple seats can have a very large frame structure, which can be difficult to maneuver, store and transport. Moreover, the seats are usually installed at fixed positions that are far from the caregiver, which does not facilitate interaction between the child and the caregiver. Therefore, there is a need for a child stroller apparatus that can be convenient to operate, and address at least the foregoing issues. SUMMARY The present application describes a child stroller apparatus that is convenient to operate, and has a mount system configurable to accommodate various detachable parts, such as one or two detachable child seats. According to one aspect, the child stroller apparatus includes a standing frame, a push handle frame having a side segment pivotally connected with the standing frame via a pivot connection, an adapter configured to couple to a detachable part by engagement of the adapter with the detachable part, and a locking mechanism for locking the adapter in a desired position on the side segment. The adapter is fixedly connected with a handle that is located behind the adapter when the child stroller apparatus is in an unfolded state for use so that the handle is slidable along the side segment for adjustment between a lowest position in which the adapter is adjacent to and at the same level as the pivot connection and a plurality of upper positions in which the adapter is spaced apart from and above the pivot connection. The locking mechanism includes a latch and a release actuator respectively connected with the handle to selectively lock the adapter in a desired one of the lowest position and the upper positions.
