Abstract
Abstract The bowden cable drivingly connecting a crank on a motorcar door to a carrier for the window in the door has a plastic compression member whose ends abuttingly engage retaining members near the crank and the window carrier. The ends are of noncircular cross section, and their angular movement about the longitudinal axis of the cable is prevented by conforming engagement with respective retaining members.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
178 words
In a window operating mechanism including a window carrier movable in a predetermined path, a driving device, an elongated bowden cable including a tension member and a compression member, said tension member drivingly connecting said carrier and said device, and said compression member being formed with a longitudinal bore therethrough receiving said tension member, and retaining means associated with respective, longitudinally terminal portions of said compression member adjacent said carrier and said device respectively for abuttingly retaining the associated portions, the improvement which comprises: (a) said compression member essentially consisting of flexible material, and at least one of said longitudinally terminal portions thereof being of non-circular cross section, (b) the retaining means associated with said one portion including a retaining member conformingly engaging said one portion and thereby preventing angular movement of the engaged portion about an axis longitudinal of said bowden cable, and (c) said retaining member being formed with a recess receiving said one longitudinally terminal portion, and said retaining means including yieldably resilient means opposing longitudinal movement of said compression member inward of said recess.
Claim 2
Dependent Claim
178 words
In a window operating mechanism including a window carrier movable in a predetermined path, a driving device, an elongated bowden cable including a tension member and a compression member, said tension member drivingly connecting said carrier and said device, and said compression member being formed with a longitudinal bore therethrough receiving said tension member, and retaining means associated with respective, longitudinally terminal portions of said compression member adjacent said carrier and said device respectively for abuttingly retaining the associated portions, the improvement which comprises: (a) said compression member essentially consisting of flexible material, and at least one of said longitudinally terminal portions thereof being of non-circular cross section, (b) the retaining means associated with said one portion including a retaining member conformingly engaging said one portion and thereby preventing angular movement of the engaged portion about an axis longitudinal of said bowden cable, and (c) said retaining member being formed with a recess receiving said one longitudinally terminal portion, and said retaining means including yieldably resilient means opposing longitudinal movement of said compression member inward of said recess.
Claim 3
Dependent Claim
37 words
In a mechanism as set forth in claim 1, respective parts of said one portion and of said retaining member jointly constituting a tongue-and-groove connection securing said compression member against angular movement relative to said retaining means.
Claim 4
Dependent Claim
36 words
In a mechanism as set forth in claim 2, said part of said one portion being formed with two longitudinal grooves oppositely spaced from said axis and engaged by said part of the associated retaining member.
Claim 5
Dependent Claim
48 words
In a mechanism as set forth in claim 1, said retaining member being forked and including a stem portion and two branch portions extending from said stem portion in a common direction, said one longitudinally terminal portion being formed with two longitudinal grooves respectively receiving said branch portions.
Claim 6
Dependent Claim
27 words
In a mechanism as set forth in claim 4, said branch portions being elongated and offset from said stem portion transversely to the direction of elongation thereof.
Claim 7
Dependent Claim
223 words
In a window operating mechanism including a window carrier movable in a predetermined path, a driving device, an elongated bowden cable including a tension member and a compression member, said tension member drivingly connecting said carrier and said device, and said compression member being formed with a longitudinal bore therethrough receiving said tension member, and retaining means associated with respective, longitudinally terminal portions of said compression member adjacent said carrier and said device respectively for abuttingly retaining the associated portions, the improvement which comprises: (a) guide means for guiding said carrier in said path, said guide means including a guide member engaging said carrier during said movement of the carrier in said path; (b) said compression member essentially consisting of flexible material, and at least one of said longitudinally terminal portions thereof being of non-circular cross section; (c) the retaining means associated with said one portion including a retaining member conformingly engaging said one portion and thereby preventing angular movement of the engaged portion about an axis longitudinal of said bowden cable, said retaining member being fixedly secured to said guide member; and (d) wall means defining an elongated guide channel, said wall means being fixedly fastened to said guide member, and said channel extending from said retaining member toward said device in an arc, said bowden cable being received in said channel.
Claim 8
Dependent Claim
223 words
In a window operating mechanism including a window carrier movable in a predetermined path, a driving device, an elongated bowden cable including a tension member and a compression member, said tension member drivingly connecting said carrier and said device, and said compression member being formed with a longitudinal bore therethrough receiving said tension member, and retaining means associated with respective, longitudinally terminal portions of said compression member adjacent said carrier and said device respectively for abuttingly retaining the associated portions, the improvement which comprises: (a) guide means for guiding said carrier in said path, said guide means including a guide member engaging said carrier during said movement of the carrier in said path; (b) said compression member essentially consisting of flexible material, and at least one of said longitudinally terminal portions thereof being of non-circular cross section; (c) the retaining means associated with said one portion including a retaining member conformingly engaging said one portion and thereby preventing angular movement of the engaged portion about an axis longitudinal of said bowden cable, said retaining member being fixedly secured to said guide member; and (d) wall means defining an elongated guide channel, said wall means being fixedly fastened to said guide member, and said channel extending from said retaining member toward said device in an arc, said bowden cable being received in said channel.
Claim 9
Dependent Claim
18 words
In a mechanism as set forth in claim 6, said guide channel being substantially L-shaped in cross section.
Claim 10
Dependent Claim
18 words
In a mechanism as set forth in claim 6, said compression member essentially consisting of synthetic resin composition.
Claim 11
Dependent Claim
17 words
In a mechanism as set forth in claim 8, said composition including a tubular layer of polypropylene.
