What is claimed as new and desired to be protected by Letters Patent
is set forth in the appended claims:
1. A flexible tensile force transmitting cable system, comprising:
an axially movable cable for transmitting a tensile force;
a flexible tube for receiving said cable for axial movement of said
cable therein; and
a casing surrounding said tube for absorbing a pressure force, said
cable being axially movable relative to said tube and said casing,
said casing including a plurality of form-parts joined to one another
to form a continuous axial passageway defined by an inside dimension
of varying diameters, said form-parts having abutting end faces
between adjacent form-parts with complementary configurations enabling
dispositions of said casing along arcuate paths, said form-parts being
stringed on and traversed by said tube, said tube having an outside
diameter that is equivalent to a smallest inside diameter of said
form-parts.
2. The cable system of claim 1, wherein, for each of said form-parts,
one of said end faces thereof has a concave configuration and the
other one of said end faces thereof has a convex configuration.
3. The cable system of claim 1, wherein a first set of said form-parts
is alternately joined to a second set of said form-parts, said first
set of form-parts having opposite convex end faces, said second set of
form-parts having opposite end faces, each having one of a concave
shape and an annular shape.
4. The cable system of claim 3, wherein each of said first set of
form-parts has an inside dimension corresponding to a cross section of
said tube, said passageway in said second set of said form-parts
having an inside dimension exceeding said cross section of said tube.
5. The cable system of claim 1, wherein said tube is made of plastic.
6. The cable system of claim 1, wherein said form-parts are made of a
material selected from the group consisting of plastic and ceramic.
7. The cable system of claim 1, wherein fittings secure said casing at
opposite ends of a frame assembly.
8. A flexible tensile force transmitting cable system, comprising:
a cable for transmitting a tensile force;
a flexible tube for accommodating the cable; and
a casing surrounding said tube for absorbing a pressure force, said
cable being axially movable relative to said tube and said casing,
said casing including a plurality of form-parts joined to one another
to form a continuous axial passageway defined by an inside dimension
of varying diameters, said form-parts having abutting end faces
between successive form-parts with complementary configurations
enabling dispositions of said casing along an arcuate path, said tube
having an outside dimension corresponding to an inside dimension of
the passageway, each of said form parts having an interior recess
forming a section of said axial passageway with an interior dimension
with a diameter exceeding that of the tube for creating a space for
compensatory movement of said tube within said axial passageway when
the cable therein transmits a tensile force.
9. The cable system of claim 8, wherein said form-parts have opposite
end faces, one of the end faces thereof has a concave configuration
and the other one of said faces thereof has a convex configuration.
10. The cable system of claim 8, wherein a first set of the form-parts
is alternately joined to a second set of the form-parts, with said
first set of form-parts having opposite end faces of convex
configuration, and with said second set of form-parts having opposite
end faces of a configuration selected from the group consisting of a
concave shape and an annular shape.
11. The cable system of claim 8, wherein said tube is made of plastic.
12. The cable system of claim 8, wherein said form-parts are made of a
material selected from the group consisting of glidable plastic and
ceramic.
13. A pull cable system, comprising:
a cable for transmitting a tensile force; and
a casing surrounding said cable for absorbing a pressure force, said
cable being axially movable relative to said casing, said casing being
composed of a plurality of form-parts joined to one another in
end-to-end disposition to form a continuous axial passageway, each of
said form-parts having a circumferential cylindrical collar centrally
located thereon, said form-parts having abutting end faces between
successive form-parts with complementary configurations enabling
dispositions of said casing along an arcuate path, said axial
passageway defined by varied inside dimensions.
