Abstract
Abstract There is disclosed an automatic lubricating device for a remotely operable bowden cable which consists of an outer wire and an inner wire relatively frictionally slidably inserted in said outer wire and which is connected between operating means and actuating means so that the actuating means may be remotely operated by pulling the inner wire of the bowden cable, wherein an oil cover provided with an inner-wire receiving aperture is interposed between an outer-wire holding cap directly supporting the end of the outer wire and an oil cover attaching bracket fixed to one or each of said operating and actuating means, and lubricating oil is enclosed in a lubricating oil storage chamber formed in said oil cover, said lubricating oil being applied to the inner wire inserted in said inner-wire receiving aperture, the arrangement being such that the back and forth movement of the inner wire produced as a result of the operation of the operating means is utilized to cause said lubricating oil to flow along the relative slide interface between the inner and outer wires.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
246 words
In a remotely operating device including operating means having a fixed housing and an operating lever grippably pivotally mounted on said housing; actuating means disposed remotely from said operating means; and a bowden cable including an outer wire and an inner wire for interconnecting said operating means and said actuating means, the improvement comprising an automatic lubricating means for the bowden cable, said lubricating means comprising a bracket projecting from the housing and having an inner-wire receiving hole; an outer-wire holding means threadedly coupled to said bracket, for adjusting the outer wire said outer-wire holding means having a recess for receiving the outer wire and an inner-wire receiving hole; wherein when the outer-wire holding means is coupled to the bracket, an adjustable volume lubricating oil storage chamber is defined by the bracket and the outer-wire holding means; wherein one end of the inner wire is connected to the actuating means while the other end is passed through said receiving holes and said lubricating oil storage chamber and is connected to the operating lever and one end of the outer wire is connected to the actuating means and the other end is fitted in said recess of the outer-wire holding means; and wherein the interior of the bowden cable, between the outer and inner wires, communicates with said lubricating oil storage chamber through the inner-wire receiving hole formed in the outer-wire holding means whereby lubricating oil flows between said inner and outer wires thereby reducing friction therebetween.
Claim 2
Dependent Claim
246 words
In a remotely operating device including operating means having a fixed housing and an operating lever grippably pivotally mounted on said housing; actuating means disposed remotely from said operating means; and a bowden cable including an outer wire and an inner wire for interconnecting said operating means and said actuating means, the improvement comprising an automatic lubricating means for the bowden cable, said lubricating means comprising a bracket projecting from the housing and having an inner-wire receiving hole; an outer-wire holding means threadedly coupled to said bracket, for adjusting the outer wire said outer-wire holding means having a recess for receiving the outer wire and an inner-wire receiving hole; wherein when the outer-wire holding means is coupled to the bracket, an adjustable volume lubricating oil storage chamber is defined by the bracket and the outer-wire holding means; wherein one end of the inner wire is connected to the actuating means while the other end is passed through said receiving holes and said lubricating oil storage chamber and is connected to the operating lever and one end of the outer wire is connected to the actuating means and the other end is fitted in said recess of the outer-wire holding means; and wherein the interior of the bowden cable, between the outer and inner wires, communicates with said lubricating oil storage chamber through the inner-wire receiving hole formed in the outer-wire holding means whereby lubricating oil flows between said inner and outer wires thereby reducing friction therebetween.
Claim 3
Dependent Claim
37 words
A remotely operating device as set forth in claim 1 wherein said outer-wire holding means, comprises an oil cover threadedly coupled to said bracket and a holder cap having said recess therein coupled to said oil cover.
Claim 4
Dependent Claim
29 words
A remotely operating device as set forth in claim 1 wherein said outer-wire holding means comprises an oil cover having an integrally formed front portion with said recess therein.
Claim 5
Dependent Claim
23 words
A remotely operating device as set forth in claim 1 wherein a felt member impregnated with oil is provided in said oil chamber.
Claim 6
Dependent Claim
