Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a window glass open position regulating device particularly suitable for a window regulator for raising and lowering a window glass of an automobile.

2. Description of the Related Art In the one in which a door glass that is moved up and down by a window regulator is arranged in a window part of a door, a bottom dead center position switching means for switching the bottom dead center position when the door glass is opened to upper and lower stages is provided. An automobile door window opening / closing structure provided with an operating means for switching the bottom dead center position switching means is proposed as Japanese Utility Model Laid-Open No. 62-96476.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the one disclosed in Japanese Utility Model Laid-Open No. 62-96476, a carriage attached to a geared wire is used when the restriction of the lowering of the windshield by the stopper of the bottom dead center position switching means is released. Since it interferes with the rotation of the stopper, if the window glass is once raised by the handle via the geared wire and the carriage does not escape upward with respect to the stopper, the stopper can be operated even if the manual lever of the operating means is operated. I couldn't rotate smoothly because of the link.

Moreover, if the stopper is used to rotate the window glass while the lowering of the window glass is being restricted by the stopper, a large load acts on the stopper because the window glass is attached to the carriage, and the carriage is moved upward by the rotation of the stopper. If it does not move to the position, the stopper cannot be unlocked from the carriage, a large force is required to rotate the stopper, and slack may occur in the geared wire.

SUMMARY OF THE INVENTION The object of the present invention is to solve the above-mentioned problems, only by sliding the switching piece with respect to the holding body, the switching piece rotates the stopper ring with respect to the guide tube, and a part of the stopper ring is moved. The guide ring of the guide tube is closed, and the stopper ring blocks the downward movement of the carriage that moves along the guide groove of the guide tube, and the downward movement of the window glass is reliably regulated by the stopper ring. The carriage does not obstruct the rotation of the stopper ring with respect to the guide tube, even if the stopper ring is rotated with respect to the guide tube while the stopper ring keeps the window glass from descending. Therefore, it is not necessary to move the carriage upward along the guide groove of the guide tube, and the stopper ring is designed as a guide tube. When the groove is opened, the restriction of the window glass descending by the stopper ring is released, the rotation of the stopper ring prevents the carriage from moving upward along the guide groove of the guide tube, and the rotation of the stopper ring requires a large force. It is an object of the present invention to provide a device for restricting an open position of a window glass that does not require a cable and does not cause slack in a cable.

Means for Solving the Problems A window glass open position restricting device of the present invention is provided with a cable movably in an axial direction inside a guide tube, and a window glass provided on the cable via a carriage. A guide groove for guiding the carriage along the longitudinal direction is formed, and a stopper ring for preventing movement of the carriage is rotatably arranged outside the guide tube, and the guide ring guides the guide tube on the stopper ring. A groove along the groove is formed, and a holding body held by the guide tube is provided at both ends of the stopper ring, and a switching piece for rotating the stopper ring with respect to the guide tube is slidable on the holding body. It has a configuration characterized by being provided.

When the cable inside the guide tube is moved up and down, the carriage moves up and down in the longitudinal direction of the guide tube together with the window glass and the cable while engaging with the guide groove formed in the guide tube along the longitudinal direction. When the switching piece slides with respect to the holding body, the switching piece rotates the stopper ring with respect to the guide tube.

When a part of the stopper ring blocks the guide groove of the guide tube, the stopper ring blocks the downward movement of the carriage and the stopper ring regulates the lowering of the window glass, and the groove of the stopper ring guides the guide tube. At the same position as the groove, the stopper ring opens the guide groove of the guide tube, the carriage passes through the guide groove of the guide tube, and the restriction of the downward movement of the window glass by the stopper ring is released.

The stopper ring is formed by bending a flat plate-shaped metal plate having a plurality of engaging holes into a ring shape.

It is also possible to provide the stopper ring with a plurality of engagement protrusions and to provide the switching piece with a plurality of engagement holes with which the engagement protrusions of the stopper ring engage.

Effect of the Invention As described above, according to the open position restricting device for a window glass of the present invention, the cable is provided inside the guide tube so as to be movable in the axial direction, and the window glass is provided on the cable through the carriage. , A guide groove for guiding the carriage along the longitudinal direction is formed in the guide tube, and a stopper ring that blocks the movement of the carriage is rotatably arranged outside the guide tube. By forming a groove along the stopper ring, a holder for holding the guide tube at both ends of the stopper ring, and a switching piece for rotating the stopper ring with respect to the guide tube slidably provided on the holder, the switching piece The sliding piece rotates the stopper ring with respect to the guide tube only by sliding the stopper ring against the holding body, and a part of the stopper ring moves to the guide tube. Since the stopper ring blocks the downward movement of the carriage that moves along the guide groove of the guide tube by closing the guide groove of the groove, the downward movement of the window glass can be reliably regulated by the stopper ring. The ring can be easily attached to the guide tube.

In addition, even if the stopper ring rotates with respect to the guide tube while the stopper ring keeps the downward movement of the window glass, the carriage does not interfere with the rotation of the stopper ring with respect to the guide tube. When the stopper ring opens the guide tube guide groove, it is not necessary to move it upward along the tube guide groove, and the stopper ring does not prevent the carriage from moving downward, and the stopper ring lowers the window glass. Can be released, and since the carriage does not move upward along the guide groove of the guide tube due to the rotation of the stopper ring, a large force is not required to rotate the stopper ring, and the slack in the cable There is no fear of causing.
