Description

Safety seat convertible into push chair

Technical Field

The utility model relates to an infant product, in particular to a safety seat.

Background

Babies, children or pets and the like are a cumbersome and complex activity with fostering people, especially when traveling involves both vehicle travel and pedestrian travel such as walking, striding or running. Vehicle safety seats are available, which may be attached to a car seat or to a bicycle. However, when arriving at the destination, the user needs to lift and carry with both hands or keep in a push chair (also called a stroller), which needs to be carried in addition with the vehicle safety seat. The push chair occupies the space of the vehicle and increases the weight. More expense is involved in purchasing the vehicle safety seat and push chair separately. Furthermore, each transport of the pushchair is a cumbersome activity, as many operations are involved, such as folding, keeping the vehicle in storage, removing it from the vehicle, unfolding, lifting and tying the straps around the baby, child or pet. Several car safety seats and pushchairs have been designed in the past. However, none of them include a utility seat that can be easily converted between a vehicle safety seat and a push chair.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like, are used in a broad sense, and for example, "connected" may be a wall-mounted connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, and a communication between two elements, and those skilled in the art will understand the specific meaning of the terms in the present invention specifically.

Referring to fig. 1 to 6, the present embodiment provides a safety seat convertible into a push chair, including a safety seat 12, a wheel base assembly 13, a converter mechanism, front wheels 15a, 15b, rear wheels 16a, 16b, a telescopic handle 17, and a light source 18.

The safety seat 12 has a seat portion 12a and a back 12 b. The seat portion 12a, when in a substantially upper right position, provides a comfortable seat for a user, such as an infant, child or pet. In one embodiment, the backrest 12b is movable from an upright configuration to a sleep configuration, enabling the user to rest in a basic sleep position. The safety seat 12 has at least one harness 12c that is wrapped around a user, such as an infant, child or pet, to prevent them from falling, thereby providing a safe and secure seat.

The wheel base assembly 13 is composed of four walls 13a, 13b, 13c and 13 d. The front wall 13a has a turned portion so as to surround a closed area in four walls or to open the closed area. The wheel base assembly 13 also has a top portion 13e and a receiving space 13 f. The top portion 13e is a flat surface for receiving the seat portion 12a of the safety seat 12, the seat portion 12a being securely clamped to the top portion 13e by clamping elements such as bolts, nails, glue or other similar clamping devices or combinations thereof to form an integral structure therebetween. The seat portion 12a is optionally press-fit into the top portion 13e, whether or not additional clamping elements are required.

The housing space 13f is configured to selectively accommodate the pivot mechanism, the front wheels 15a, 15b, and the rear wheels 16a, 16 b. Specifically, the front wheels 15a and 15b are pivotally connected to the inner wall of the turning part via a shaft, and when the front wheels are stored, the front link 15c of the pivotal connection mechanism is folded, either manually or automatically, and the front link 15c is folded using the first switch so that the front wheels 15a and 15b can be hidden in the storage space 13 f. With the front wheels 15a, 15b, the front wall 13a is pivotally moved to a closed position so that the wheel base assembly 13 forms a housing having a full perimeter. Thus, the safety seat 12 can be positioned directly on the seat of the vehicle.

In addition, when storing, the rear wheels 16a, 16b are also folded and stored by the second link 16c of the manual or automatic folding switch mechanism, and the rear wheels 16a, 16b are folded by the second link 16c by the second switch, so that the rear wheels 16a, 16b can be hidden in the storage space 13 f.

In the unfolding mode, the first switch drives the first link 15c and the front wheels 15a and 15b to pivot, so that the front wheels 15a and 15b are projected from the accommodating space 13 f. After the front wheels 15a, 15b are projected, the front wall 13a is pivotally flipped open so that the front wheels 15a, 15b are in contact with the ground. Similarly, the second switch also moves the second link 16c and the rear wheels 16a, 16b so that the rear wheels 16a, 16b contact the ground.

To facilitate the pushing by the user, a telescopic handle 17 is provided in this embodiment, and when the safety seat 12 is used as a safety seat, the telescopic handle 17 is retracted. When the safety seat 12 is used as a push chair, the telescopic handle is extended, so that the parents can conveniently hold and push the safety seat.

In this embodiment, the mounting seat 12 further includes side wings extending forward from both sides of the backrest 12b, the side wings having a top and a bottom in the height direction of the backrest. The top and bottom portions are each provided with a light source 18 for illuminating the surrounding area, typically the frontal area, of the safety seat 12. This is an advantageous feature, which facilitates the parents' view of the street/ground, while facilitating the use of the push chair at night. Further, when the safety seat 12 is positioned in a vehicle, the light source 18 may act as a projector, attracting and entertaining users during commutes. The light source 18 may be an LED lamp that can be turned on and off by using a light switch. The optical switch may be provided anywhere throughout the device.

The safety seat 12 may additionally be provided with at least one lift handle to allow for lifting of the safety seat 12 and removal of the safety seat 12 into and out of the vehicle. The lifting handle may be mounted on the body of the safety seat 12 or the body of the housing 13. Optionally, the safety seat 12 may provide one or more other functions, such as a light shield to protect the user from the environment of sunlight, rain, and cold, storage area to store the user's needs, a locking mechanism to lock the safety seat 13 to the seat of the vehicle, and other functions.

The above description is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any person skilled in the art can make insubstantial changes in the technical scope of the present invention within the technical scope of the present invention, and the actions infringe the protection scope of the present invention are included in the present invention.
