Free movement preventing device for window glasses of automobiles

Claim 2

In an automotive vehicle including panel means which has at least one window opening and a window glass mounted in said panel means for movement substantially in a vertical direction between a closed position wherein the window glass closes the window opening and an open position wherein the window opening is fully opened and weather strips mounted along said window opening on each side of said window glass, the improvement comprising window glass mounting means including window glass support bracket means secured to the window glass, substantially vertically extending guide rail means stationarily disposed in said panel means, guide follower means for slidably connecting said bracket means to said guide rail means and for guiding said window glass along said guide rail means, power means for moving said window glass in the vertical directions, and pressing means secured to a part of said panel means spaced substantially below the weather strips mounted along said window opening to be in continuous frictional contact with only the inside of said window glass and to continuously limit the rotation of a lower part of said window glass toward the inside of said automotive vehicle.

Claim 3

A free movement preventing device for window glasses in accordance with claim 1 in which said pressing means includes an engagement element and is slidably attached on an oblique side portion of said panel means whereby an engagement pressure of said engagement element of said pressing means on said window glass may be adjusted.

Claim 4

A free movement preventing device for window glasses in accordance with claim 2 in which said window glass is at its lower part provided, with spacer means, and said engagement element is brought into contact with said spacer means and hence said window glass when said window glass is in the closed position, thereby limiting the inward deflection of the lower part of said window glass.

Claim 5

A free movement preventing device for window glasses in accordance with claim 2 in which said pressing means is mounted on the part of said panel means along a vertical line measured from the crossing point of a front edge and an upper edge of the window glass.

Claim 6

A free movement preventing device for window glasses in accordance with claim 2 in which said engagement element of said pressing means is secured to a body thereof having channel shaped cross-sectional configuration, and a bottom wall of said body is secured to said panel means through an elongated slot provided on said oblique side portion thereof.

Claim 7

A free movement preventing device for window glasses in accordance with claim 5 in which said engagement element comprises a roller which is rotatably mounted on said body of said pressing means.

Claim 8

A free movement preventing device for window glasses in accordance with claim 5 in which said engagement element comprises strip means secured to said body of said pressing means.

Claim 9

A free movement preventing device for window glasses in accordance with claim 5 in which said panel means comprises an outer panel and an inner panel to which said pressing means is attached.

Claim 10

In an automotive vehicle including panel means which has at least one window opening and a window glass mounted in said panel means for movement substantially in vertical directions between a closed position wherein the window glass closes the window opening and an open position wherein the window opening is fully opened and weather strips mounted along said window opening on each side of said window glass, the improvement comprising window glass mounting means including window glass support bracket means secured to the window glass, substantially vertically extending guide rail means stationarily disposed in said panel means, guide follower means for slidably connecting said bracket means to said guide rail means and for guiding said window glass along said guide rail means, power means for moving said window glass in the vertical directions, pressing means, including a body portion and a roller, secured to said panel means and spaced substantially below said weather strips to be in continuous contact with only the inside of said window glass and to continuously limit the deflection of a lower part of said window glass toward the inside of said automotive vehicle, said pressing means being slidably attached on an oblique said portion of side panel means so as to adjust an engagement pressure of the roller of said pressing means on said window glass, said roller of said pressing means being rotatably secured to the body portion of said pressing means, said body portion having a channel shaped cross-sectional configuration, and a bottom wall of said body portion being secured to said panel means through an elongated slot provided on said oblique side portion thereof.

Claim 11

In an automotive vehicle including panel means which has at least one window opening and a window glass mounted in said panel means for movement substantially in vertical directions between a closed position wherein the window glass closes the window opening and an open position wherein the window opening is fully opened and weather strips mounted along said window opening on each side of said window glass, the improvement comprising window glass mounting means including window glass support bracket means secured to the window glass, substantially vertically extending guide rail means stationarily disposed in said panel means, guide follower means for slidably connecting said bracket means to said guide rail means and for guiding said window glass along said guide rail means, power means for moving said window glass in the vertical directions, pressing means, including a body portion and a roller, secured to said panel means and spaced substantially below said weather strips to be in continuous contact with only the inside of said window glass and to continuously limit the deflection of a lower part of said window glass toward the inside of said automotive vehicle, said pressing means being slidably attached on an oblique said portion of side panel means so as to adjust an engagement pressure of the roller of said pressing means on said window glass, said roller of said pressing means being rotatably secured to the body portion of said pressing means, said body portion having a channel shaped cross-sectional configuration, and a bottom wall of said body portion being secured to said panel means through an elongated slot provided on said oblique side portion thereof.

Claim 12

A free movement preventing device for window glasses in accordance with claim 9 in which said window glass is at its lower part provided with spacer means, and said roller is brought into contact with said spacer means and hence said window glass when said window glass is in the closed position, thereby limiting the inward deflection of the lower part of said window glass.
