Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates to a waning device for generate a safety signal and, more particularly, to a warning device which is mountable either on a stroller frame or a safety seat for generating the signal while the safety seat is safely connected with the stroller.
2. Description of the Related Art
Stroller and car seat becomes a necessity to every family having an infant or baby. The conventional foldable stroller is considered as a convenience tool to carry the baby or young child during outdoor activities such as foot traveling and shopping. According to rules and regulations, the car seat must be employed in every vehicle for transporting the baby or young child. Therefore, the stroller and the car seat play the main role for the parents to carry their babies.
However, it is a hassle for the parent to move the baby back and forth from the safety seat to the stroller. Especially when the baby falls asleep, the parent may merely wake him or her up while moving him or her from/to the safety seat to/from the stroller. Once the baby wakes up, the parent may take longer time to soothe him or her back to sleep.
Therefore, the parent may put the safety seat on the stroller so as to carry the safety seat and the stroller at the same time. In U.S. Pat. No. 5,676,386, a baby stroller is provided with an engaging device for the parent to move the baby from the car to the stroller without waking up the baby. As the engaging device is a complex mechanism, the user cannot make sure whether the safety seat has been safely engaged to the stroller.

SUMMARY OF THE INVENTION

To overcome the shortcomings, the present invention intends to provide a warning device to help the user to make sure the safety of the engagement between the safety seat and the stroller.
A warning device according to the present invention includes a safety seat, a baby stroller frame and an electronic device. The safety seat has a seat body, a handle and a pair of connecting elements; the baby stroller frame has a connecting base provided with a pair of receptacles adapted for engaging with the connecting elements. In addition, the electronic device has at least a signal generating element, a battery, electronic circuit and at least a first touching switch received in either one of the receptacles or the connecting elements for generating a safety signal when the connecting elements is fully inserted into the receptacles. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 1 to 4, an embodiment of warning device according to the present invention includes a safety seat 2, a baby stroller frame 3 and an electronic device 4. The safety seat 2 has a seat body 21, a handle 22 and a pair of connecting elements 23.
The baby stroller frame 3 has a connecting base 31 provided with a pair of receptacles adapted for engaging with the connecting elements 31. The baby stroller frame 3 may further comprise a pair of opposed side portions 32 for installing the electronic device 4 which has at least a signal generating element 46, a battery 45, and electronic circuit (not shown) and at least a first touching switch 42 which is receivable in either one of the receptacles 311 or the connecting elements 23 for generating a safety signal when the connecting elements 23 is fully inserted into the receptacles 311.
In this embodiment, the first touching switch 42 is mounted inside the receptacles 311. The connecting elements 31 each comprises a plug 231 for inserting into the receptacles 311 so as to connect the safety seat 2 to the baby stroller frame 3. While the plug 231 is fully inserted into the receptacles 311 and touched the first touching switch 42, the signal generating element 46 is generating a safety signal for showing the connection between the plug 231 and the receptacles 311 has been safely completed.
Preferably, the handle 22 may formed with a pair of latch 232 for locking the safety seat 2 to the baby stroller frame 3 that prevents the plug 231 leaving the receptacles 311. Referring to FIG. 2, the handle 22 is rotatable and positionable by a positioning mechanism 24. The handle 22 can be positioned in an accessible position 10, a securing position 20 and a supporting position 30. Referring to FIGS. 2 and 5, while the handle 22 is rotated from the accessible position 10 to the securing position 20, the latch 232 is relatively rotated to a position that locks the safety seat 2 to the baby stroller frame 3.
Oppositely, when the handle 22 is rotated and positioned in the accessible position 10, the latch 232 is relatively rotated to an unlocked position, this permits the safety seat 2 to be moved from the stroller frame 3. Further, when the handle 22 is rotated and positioned at the supporting position 30, it would help to steady the safety seat 2 against a possible rocking.
Persons of ordinary skill in the art will appreciate that the connecting base 31 may be formed with a pair of latching slot 312 as shown in FIG. 3 for engaging with the latch 232.
Referring to FIG. 4, the electronic device 4 may further comprise a control panel 41, a power switch, and a second touching switch 43 which installed inside the latching slot 312. While the latches 232 is fully engaged into the latching slot 312 and touched the second touching switch 43, the signal generating element 46 is then generating a safety signal, for instance a sound or light for showing the engagement thereof has been safely completed.
Persons of ordinary skill in the art will further appreciate that, although in the preferred example, the first and second touching element 42 and 43 are connected inside the receptacles 311 and the latching slot 312, but either could alternatively be installed at the plug 231 and the latch 232 for showing the safety seat 2 is safely connected to the baby stroller frame 3.
Although certain apparatus constructed in accordance with the teachings of the invention have been described herein, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all embodiments of the teachings of the invention fairly falling within the scope of the appended claims either literally or under the doctrine of equivalents.
