Description

[Detailed Description of the Invention] The present invention relates to a child proof interlocking door glass lowering control device.

Conventional childproof devices only restrict the opening and closing of doors, but this device allows children to lower the window glass without permission, which is extremely dangerous.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a child-proof interlocking door glass lowering regulating device that can simultaneously regulate the opening/closing of a door and the amount of lowering of the door glass.

The child-proof interlocking door glass lowering regulating device according to the present invention is configured to achieve the above object by providing a mechanism that also regulates the amount of descent of the door glass in conjunction with the child-proof of the door.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a door glass lowering control device linked to a childproof door according to the present invention will be described below with reference to FIGS. 1 to 4. FIG. FIG. 1 is a perspective view of a window regulator and a door glass lowering restriction device, and FIG. 2 is a detailed view of the door glass lowering restriction device. In FIG. 1, 1 is a door glass, and an X-shaped lift arm 2 is connected to the lower end of the door glass. Further, the spiral spring 3, the sector gear 4, the pinion 5, and the regulator handle shaft 6 constitute a door glass elevating means, and the elevating means is provided on the lift arm. Furthermore, a pin 2a as an engaging portion is formed at the end of the lift arm 2.
is slidably engaged with a guide groove 9 formed in the door. In FIG. 2, 7 and 8 are links that are pivotally supported by shafts 7a and 8a, respectively. When the lever 7b of the link 7 is turned counterclockwise, the link 8 is also rotated counterclockwise via the rod 10, and the tip 8b of the link 8 as a regulating member is inserted into the guide groove 9 formed in the door. The lowering amount of the door glass 1 is regulated to be safe for children.

Next, the operation of the above embodiment will be explained.

FIG. 3a shows a case where the mechanism for regulating the amount of descent of the door glass is free, that is, when the tip 8b of the link 8 is in a position where the door glass can be fully opened. Since the pin 2a serving as a joint can freely slide within the guide groove 9, a child can lower the window glass without permission as shown in FIG. 3b, which is extremely dangerous. In this embodiment, when the lever 7b of the door glass lowering amount regulating mechanism is turned counterclockwise and locked in conjunction with the child proof of the door, this movement is transmitted to the link 8 via the rod 9, and the link 8 is moved counterclockwise. The tip 8b of the link 8 is fitted into the guide groove 9 corresponding to the door glass opening degree that is safe for children, and at that position, the movement of the pin 2a at the lower end of the lift arm 2 of the window glass 1 is blocked at point L. As a result, the amount of descent of the window glass 1 can be limited to a level that is not dangerous, as shown in FIG. 4b.

As mentioned above, the present invention is equipped with a mechanism that regulates the amount of descent of the door glass in conjunction with the childproof door opening/closing mechanism, thereby significantly improving safety when a child is seated in a car.

Claims (1)

[Scope of utility model registration request] A door glass disposed on the door so that it can be raised and lowered; a lift arm that supports the door glass and is pin-coupled in an X shape; an engaging part provided at the lower end of the lift arm; and a guide for the engaging part. a door glass raising/lowering means for swinging the lift arm to raise and lower the door glass; and a door glass lifting means that is fitted into the guide groove and locks the engaging portion when the door glass is opened at a child-safe door glass opening. The present invention also includes a regulating member that moves out of the guide groove and occupies a position that does not impede movement of the engaging portion when the door glass can be fully opened, and a link mechanism that moves the regulating member in conjunction with a child-proof mechanism.
