Warning device for a car seat base
View Patent ↗A warning device for a car seat base includes a car seat base, a support leg and a color signal revealing mechanism. The car seat base is capable of mounting on a vehicle seat and provided with a support face for supporting a car seat thereupon and a signal window for showing signals by colors. The support leg is movably and rotably mounted to the car seat base. Once the length of the support leg is not yet good enough to abut the car seat base, or someday the lock means of the support leg is failed, the weight of the support leg would carry itself moving downward, by this way to cause the signal element to reveal a warning signal from signal window to the user.
1. A warning device for a car seat base, including:
a car seat base ( 1 ), capable of mounting on a vehicle seat ( 100 ), having a support face ( 13 ) for supporting a car seat ( 20 ) thereupon and a signal window ( 17 ) for showing signals by colors;
a support leg ( 2 ), movably and rotably mounted to the car seat base ( 1 ), having a folded position ( 21 ), an unloaded erecting position ( 22 ) and a loaded erecting position ( 23 ); and
a color signal revealing mechanism ( 4 ) installed between the car seat base ( 1 ) and the support leg ( 2 ), including a signal element ( 41 ) and an abutting element ( 44 ); wherein the abutting element ( 44 ) has an upper end pivoted with the signal element ( 41 ), and a lower end for abutting upward by the support leg ( 2 ) when the support leg ( 2 ) is moved to the loaded erecting position ( 22 ); and wherein the signal element ( 41 ) is associated with the support leg ( 2 ) through the abutting element ( 44 ), and when the support leg ( 2 ) is moved to the unloaded erecting position ( 22 ), the signal element ( 41 ) reveals a first color area ( 42 ) from the signal window ( 17 ); and when the support leg ( 2 ) is moved to the loaded erecting position ( 22 ), the signal element ( 41 ) reveals a second color area 43 ) from the signal window ( 17 ).
2. The warning device for a car seat base of claim 1 , wherein the signal element ( 41 ) is a rotor having the first color area ( 42 ) and the second color area 43 ).
3. The warning device for a car seat base of claim 1 , wherein the support leg ( 2 ) includes an upper tube ( 24 ) and a lower tube ( 25 ) telescopically and lockably connected with the upper tube ( 24 ); wherein the lower tube ( 25 ) can be locked in a position to stick on a vehicle floor ( 10 ), and let the upper tube ( 24 ) to support the weight of the car seat base ( 1 ) in the loaded erecting position ( 23 ).
4. The warning device for a car seat base of claim 1 , wherein abutting element 44 is biased by a resilient element ( 45 ) to keep the signal element ( 41 ) revealing the first color area ( 42 ) before the support leg ( 2 ) moving to the loaded erecting position ( 23 ).
5. The warning device for a car seat base of claim 1 , wherein the support leg ( 2 ) is substantially parallel to a downside of the car seat base ( 1 ), when being rotated to the folded position ( 21 ).
6. The warning device for a car seat base of claim 1 , wherein the car seat base ( 1 ) has a pair of rear extending coupling element ( 12 ) for connecting to a vehicle fixed point (ISOFIX) ( 11 ).
7. The warning device for a car seat base of claim 1 , wherein the car seat base ( 1 ) has a plurality of hooks ( 14 ) for retaining the car seat ( 20 ) atop the support face ( 13 ).
8. The warning device for a car seat base of claim 1 , wherein the car seat base ( 1 ) has a pivot mount ( 16 ) formed with a slot ( 26 ) for guiding the support leg ( 2 ) to move between the unloaded erecting position ( 22 ) and the loaded erecting position ( 23 ), and permitting the support leg ( 2 ) to rotate between the unloaded erecting position ( 22 ) and the folded position ( 21 ).
9. The warning device for a car seat base of claim 8 , wherein the support leg ( 2 ) is pivoted to the pivot mount ( 16 ) by a pivot pin ( 27 ), and the pivot mount ( 16 ) is inserted through the support leg ( 2 ) and the slot ( 26 ), so as to keep the support leg ( 2 ) to be retained within the slot ( 26 ) and capable of rotation, moving upward and downward.
