Vehicle window arrangement having an angled opening for inserting a cable end during assembly
View Patent ↗A window-raising device for a vehicle provides a two-cable winding drum, a hood to support and partially surrounding the drum on a support plate to form a cable passage. A flange extends from the winding drum to support sliding movement of an end of one of the cables. An opening in the flange is defined by an outer side ramp that is angled relative to an axis of rotation of the drum. The ramp is positioned between two walls that are roughly parallel to the axis of the drum and formed below the flange. The present invention thereby permits a reduction in the total height of the winding drum for the same number of grooves. The cable is inserted at an angle relative to the axis of the drum by sliding it on the ramp. Thus, the drum and the device as a whole are made more compact.
1. A device for raising and lowering a vehicle window, comprising:
a cable having two ends;
a drum having a plurality of grooves on an outer surface of the drum for receiving portions of the cable, a first end of the drum having a receiver that receives one of the cable ends, a second end of the drum including a flange extending radially outward further than the grooves, the flange including an opening extending axially through the flange; and
a hood having a sidewall partially surrounding the drum, the sidewall and a portion of the drum flange cooperating to form an arcuate passage, a second end of the cable being received through the arcuate passage and into the opening in the flange.
2. The device of claim 1 , wherein the hood sidewall includes a first axial portion, a radially extending portion and a second axial portion that extends between the radially extending portion and the drum flange and wherein the second end of the cable is received between the radially extending portion and the drum flange and the second axial portion and a body of the drum, respectively.
3. The device of claim 1 , wherein the opening in the flange is adjacent a ramp that extends at an angle relative to an axis of the drum.
4. The device of claim 3 , wherein the angle of the ramp is approximately 45 degrees relative to the axis of the drum.
5. The device of claim 3 , including a sidewall on opposite sides of the ramp, each sidewall extending in a direction generally parallel to the axis of the drum.
6. The device of claim 1 , including projections extending from the drum flange in an axial direction and including a brake box having projections that cooperate with the flange projections such that rotation of the brake box projections causes rotation of the drum.
7. The device of claim 6 , wherein the opening in the flange extends into one of the drum flange projections.
8. The device of claim 7 , wherein the one drum projection includes an angled ramp surface that is angled relative to an axis of the drum, the angled surface guiding the second end of the cable into the opening.
9. A vehicle window raiser assembly, comprising:
a cable;
a winding drum having a body portion that has a plurality of grooves that support a portion of said cable for winding said cable, the drum having a radially extending flange at one end of the body portion extending radially outward further than the grooves, the flange including an opening; and
a hood having a sidewall extending along a portion of the length of the drum body portion at a first radial dimension and a passage portion having a second, larger radial dimension, the passage portion and the drum flange cooperating to form a tunnel that guides and supports an end of the cable prior to the end of the cable being inserted into the opening in the flange.
10. The assembly of claim 9 , wherein the drum flange has a radial dimension that is approximately equal to the second radial dimension of the passage portion of the hood.
11. The assembly of claim 9 , including projections extending from the drum flange in an axial direction and including a brake box having projections that cooperate with the flange projections such that rotation of the brake box projections causes rotation of the drum.
12. The assembly of claim 11 , wherein the opening in the flange extends into one of the drum flange projections.
13. The assembly of claim 12 , wherein the one drum projection includes an angled ramp surface that is angled relative to an axis of the drum, the angled surface guiding the end of the cable into the opening.
14. The assembly of claim 9 , wherein the opening in the flange is adjacent a ramp that extends at an angle relative to an axis of the drum.
15. The assembly of claim 14 , wherein the angle of the ramp is approximately 45 degrees relative to the axis of the drum.
16. The assembly of claim 14 , including a sidewall on opposite sides of the ramp, each sidewall extending in a direction generally parallel to the axis of the drum.
