3,252,256 SASH CHANNEL ASSEMBLY Raymond G. Sprecher, Detroit, Mich., assignor to Geueral Motors Corporation, Detroit, Mich., a corporation of Delaware Filed Nov. 4, 1963, Ser. No. 321,053 Claims. (Cl. 49-351) This invention relates to window regulator mechanisms and more particularly to a sash channel assembly for a vehicle body window regulator mechanism. v
One feature of this invention is that it provides an improved sash channel assembly for a vehicle body window regulator mechanism. Another feature of this invention is that it provides a sash channel assembly having spaced discontinuous walls located generally parallel with respect to each other and adapted to receive therebetween the edge portion of a glass panel. A further feature of this invention is that it provides a sash channel assembly including a support member having spaced rows of wall members providing discontinuous side walls of a sash channel adapted to receive and to be secured to the edge portion of a glass panel. Yet another feature of this invention is that the wall members of one row are nonoppositely located with respect to the wall members of the other row whereby the wall members of one row alternate with the wall members of the other row. Yet a further feature of this invention is that decorative members are releasably secured to each of the rows of wall members to conceal the wall members and the edge portion of the glass panel.
These and other features of this invention will be readily apparent from the following specification and drawings wherein:
FIGURE l is a partially broken away side elevational view of the front door of a vehicle body having a window regulator mechanism mounted therein and embodying a sash channel assembly according to this invention;
FIGURE 2 is a partially broken away view ,taken generally along the plane indicated by line 2--2 of FIG- URE l;
FIGURE 3 is an enlarged sectional View taken generally along the plane indicated by line 3 3 of FIG- URE l;
FIGURE 4 is a sectional View taken generally along the plane indicated by line 4 4 of FIGURE 1; and
FIGURE 5 is an exploded perspective View.
Referring now particularly to FIGURE l of the drawings, a conventional front door of a vehicle body mounts a conventional cross arm type of window regulator mechanism 12 which is adapted to be connected to the door window 14 to move the window between a closed position, as shown, and an open position, not shown, wherein the window 14 is located within the door well which is defined by the door inner and outer panels 16 and 18, respectively, of door 10. Window 14 opens and closes the rearward portion of the door window opening and the forward portion of the door window opening is opened and closed by a conventional pivoted type of ventilation window 20.
The sash channel assembly 22 forms the connection between the window regulator mechanism 12 and the window 14 and includes a sash or support member 24, the upper planar face 26 of which forms the base wall of the sash channel which receives the lower edge portion of the window 14 as will be described. A slotted depending tab or ear 28 at the forward end of member 24 mounts the forward guide shoe assembly and an apertured depending ear 30 adjacent the rearward end of the member 24 mounts the rear guide shoe assembly, with both guide shoe assemblies being adapted to move within United States Patent O the usual front and rear guide channels which control lateral movement of the window within the window opening and window well. The member 24 also includes a plurality of depending apertured ears 32 which are adapted to be releasably secured to upwardly extending tabs or arms of a cam channel 34 to thereby connect the sash channel assembly 22 to the window regulator mechanism 12.
Rows 36 and 38 of like generally T-shaped wall members 40 extend upwardly from the support member 24 at opposite edge portions of the planar face 26 thereof, with the rows 36 and 38 defining the discontinuous side walls of the sash channel, the base wall of which is defined by the face 26 of the member 24 as previously mentioned. Each of the wall members 40 is of like construction and includes a generally rectangularly shaped pad portion 42, the face 44 of which is broached or otherwise finished during manufacture so that the distance between the faces 44 of the rows 36 and 38 is within the desired manufacturing tolerance.
The edge portion 46 of the Window 14 is received between the faces 44 of the Wall members 40, with a rubber or other resilient channel 48 surrounding the edge portion so as to wedge this edge portion between the faces 44 of the members 40 and thus secure the support member 24 to the lower edge portion of the window 14.
Since the channel 48 will show intermediate each successive pair of wall members 40, it is desirable that'the rows 36 and 38 of wall members be provided with some type of decorative covering. As best shown in FIGURE 5, a decorative molding 52 is provided for each row of wall members, with each molding 52 including an upper return bent edge or flange 54 and lower inwardly extending hook fiange portions 56. In order to mount the moldings 52l on their respective rows of wall members, the
upper bent edge 54 of the molding is hooked over the upper edge of the wall members and located within a recess 58 thereof, as best shown in FIGURE 3, and then lwall members of vrow 38 since the molding 52 of the one row is of a different cross sectional configuration than the molding of the other row.
Thus, this invention provides an improved sash channel assembly.
1. In a vehicle body having a Window opening therein, a movable window for opening and closing the opening, and a window regulator mechanism for moving the window, a sash channel assembly for operatively connecting the window to the window regulator mechanism comprising, in combination, a support member having a generally planar face defining the base Wall of a channel and having spaced rows of wall members extending from said face and defining spaced discontinuous'walls for receiving an edge portion of the window therebetween, means .located between said wall members and the opposite faces `of the window for wedging the window between said wall members, a molding for covering each of said walls, each molding having portions thereof fitting between the members of one wall and the face of the window respective to the one wall for mounting each of said moldings on said support member, and vmeans securing said support member to the window regulator mechanism.
2. The structure recited in claim 1 wherein said means located between said wall members includes a resilient member wedged between the wall members and a respective face of the window.
3. The structure recited in claim 1 wherein said wall members include spacing means extending o-utwardly therefrom and each of said moldings engages said spacing means to locate the portions of the molding tting between the wall members and the faces of the window.
4. In a vehicle body having a window opening therein, a movable window for opening and closing the opening, and a window regulator mechanism for moving the window, a sash channel assembly for operatively connecting the window to the window regulator mechanism comprising, in combination, a support member having spaced rows of walls members defining spaced discontinuous walls for receiving an edge portion of the window therebetween, means securing the edge portion of the window to said wall members of each of said walls toA secure the window to said support member, means mounted on said wall members for covering each of said discontinuous walls, and means securing said support member to the window regulator mechanism.
5. A sash channel assembly comprising, in combination, a support member having a generally planar face dening the base wall of a sash channel and having spaced rows of generally T-'shaped wall members extending from said face and defining spaced discontinuous side walls of a sash channel adapted to receive the edge portion of a glass panel therebetween, the wall members of one of said spaced rows being nonoppositely located with respect to the wall members of the other of said rows whereby said wall members of said one row alternate with said wall members of said other of said rows, resilient means located between the shank portion of said T-shaped wall members and the faces of said panel for wedging said panel between said wall members, and a generally U- shaped decorative member covering each of said rows of wall members, said decorative member including an upper edge portion hooked over the upper edge of the cross portion of said wall members and spaced lower edge portions hooked over the lower edges of said cross portion of said wall member.
