Title: Window for vehicle cabs, especially for vehicles employed in agriculture and in construction
Claims: What we claim is: 1. In combination: a motor vehicle cab having an upper frame member extending in the transverse direction of said cab, a lower frame member arranged in substantially parallel spaced relationship to said upper frame member, and two lateral frame members respectively arranged at the opposite ends of said upper and lower frame members and laterally interconnecting the same so as to define with each other and with said upper and lower frame members a substantially quadrangular window opening with the extension thereof in the transverse direction of said cab representing the length of said window opening and with the extension transverse to said length representing the width of said window opening; a window pane covering up said window opening and having an inner side facing toward the interior of said cab and having an oppositely located outer side facing away from the interior of said cab, said window pane having a first edge adjacent and substantially parallel to said upper frame member, a second edge opposite and substantially parallel to said first edge, and two lateral edges arranged opposite to each other and respectively extending from said first to said second edge; hinge means laterally spaced from each other and partly connected to said upper frame member and partly arranged on said inner side of said pane for hingedly connecting said window pane to said upper frame member; a yoke member bridging said hinge means and being connected thereto while being associated with and located exclusively only at said inner side along the first edge of said pane but in spaced relationship thereto, web means pivotally interconnecting said yoke member and said upper frame member relative to said hinge means, said yoke member having a longitudinal section arranged at and along said first edge while extending in the transverse direction of said cab, said yoke member also having lateral legs respectively arranged at said oppositely located lateral edges, said lateral legs having those ends thereof which are remote from said longitudinal section spaced from said second edge; and actuating means arranged between said second edge and said last mentioned legs and respectively connected to said legs and said lateral frame members. 2. The combination according to claim 1, in which said legs extend from the sides of said longitudinal yoke section in the direction toward and only approximately halfway to said second edge. 3. The combination according to claim 1, in which said longitudinal yoke section forms together with said lateral legs a U-profile, and which includes elastic insert means interposed directly between said pane and said longitudinal yoke section. 4. The combination according to claim 1, in which said lateral legs extend in spaced relationship to said lateral edges of said window pane. 5. The combination according to claim 1, which includes tensioning means and spreading means associated with said tensioning means, and in which said yoke member is connected to said pane solely by spreading means and said tensioning means. 6. The combination according to claim 5, which includes elastic insert means arranged between said spreading means and said pane. 7. The combination according to claim 5, in which said pane in the region of said yoke member is provided with bores, and in which said spreading means includes screw bolt means respectively extending through the bores from said outer side of said pane while being provided with a head outwardly spaced from said outer side, elastic compressible ring means surrounding said screw bolt means within the region of said bores and between said head and said outer side of said pane, and means associated with said screw bolt means for tightening said screw bolt means to firmly press said elastic compressible ring means between said head and said pane. 8. The combination according to claim 1, which includes sealing means around the outer edges of said pane and comprising sealing lip means for sealing engagement with said upper and lower frame members of said cab in closed position of said window pane. 9. The combination according to claim 8, in which said sealing means includes a hollow elastic body having said sealing lip means arranged thereon. 10. The combination according to claim 1, which includes latch means arranged within the region of said second edge of said pane for latching said pane in closing position to said lower frame member. 11. The combination according to claim 1, which includes holding means arranged on said window pane within periphery thereof, and windshield wiper means secured directly to said holding means. 12. The combination according to claim 1, in which said upper frame member has a downward extension having said hinge means interconnecting said upper frame and said web means, and in which said hinge means are U-shaped, one of the legs of said U-shaped hinge means downward extending around said extension in open position of said pane.
