Abstract
Abstract A motion transmitting remote control assembly of the type for transmitting motion in a curved path by a flexible motion transmitting core element including a motion transmitting core element and a guide assembly for movably supporting the core element. The guide assembly includes a rigid end fitting having a bore therethrough. The core element includes a rigid bar extending therefrom and supported for reciprocating movement in the bore of the end fitting. The assembly includes a support fitting for supporting the end fitting on a support structure. The assembly is characterized by a swivel joint interconnecting the support fitting and the end fitting at an intermediate position spaced from the ends of the end fitting for allowing pivotal movement of the end fitting about the swivel joint and movement of the bar into the end fitting and through the swivel joint.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
218 words
A motion transmitting remote control assembly (10) of the type for transmitting motion in a curved path by a flexible motion transmitting core element (12), said assembly (10) comprising: a motion transmitting core element (12); guide means (14) for movably supporting said core element (12), said guide means (14) including a rigid end fitting (16) having first and second ends (18, 20) with a bore (22) therethrough and between said ends (18, 20), said core element (12) including a rigid bar (24) extending from said first end (18) of said end fitting (16) and supported for reciprocating movement in said bore (22) of said end fitting (16); support means (26) for supporting said end fitting (16) in a support structure (28); and characterized by swivel joint means (30) interconnecting said support means (26) and said end fitting (16) at an intermediate position spaced from both of said first and second ends (18, 20) for allowing pivotal movement of said end fitting (16) and said bar (24) about said swivel joint means (30) while at the same time allowing movement of said bar (24) in said end fitting (16) and through said swivel joint means (30), said guide means (14) including a flexible conduit (32) attached to and extending from said second end (20) of said end fitting (16).
Claim 2
Dependent Claim
218 words
A motion transmitting remote control assembly (10) of the type for transmitting motion in a curved path by a flexible motion transmitting core element (12), said assembly (10) comprising: a motion transmitting core element (12); guide means (14) for movably supporting said core element (12), said guide means (14) including a rigid end fitting (16) having first and second ends (18, 20) with a bore (22) therethrough and between said ends (18, 20), said core element (12) including a rigid bar (24) extending from said first end (18) of said end fitting (16) and supported for reciprocating movement in said bore (22) of said end fitting (16); support means (26) for supporting said end fitting (16) in a support structure (28); and characterized by swivel joint means (30) interconnecting said support means (26) and said end fitting (16) at an intermediate position spaced from both of said first and second ends (18, 20) for allowing pivotal movement of said end fitting (16) and said bar (24) about said swivel joint means (30) while at the same time allowing movement of said bar (24) in said end fitting (16) and through said swivel joint means (30), said guide means (14) including a flexible conduit (32) attached to and extending from said second end (20) of said end fitting (16).
Claim 3
Dependent Claim
95 words
An assembly as set forth in claim 1 wherein said swivel joint means (30) includes a spherical male portion (34) and a coacting spherical female portion (36), said support means (26) having a passageway (38) therethrough with one of said male (34) and female (36) portions disposed in said passageway (38), said support means (26) having at least one slot (40) extending parallel to said passageway (38) through said male (34) and female (36) portions for allowing said support means (26) to open during assembly to snap said male (34) and female (36) portions together.
Claim 4
Dependent Claim
38 words
An assembly as set forth in claim 2 wherein said passageway (38) is flared outward from said swivel joint means (30) in both directions for allowing said end fitting (16) to swivel about said swivel joint means (30).
Claim 5
Dependent Claim
55 words
An assembly as set forth in claim 3 wherein said support means (26) includes retaining means (46) for retaining said support means (26) in an aperture (48) in the support structure (28) which surrounds said support means (26) and prevents said support means (26) from opening to disengage said male and female portions (34, 36).
Claim 6
Dependent Claim
47 words
An assembly as set forth in claim 4 wherein said end fitting (16) is circular in cross section and said male spherical portion (34) is disposed about said end fitting (16), said female spherical portion (36) is disposed in said passageway (38) of said support means (26).
Claim 7
Dependent Claim
123 words
An assembly as set forth in claim 5 wherein said support means (26) comprises a snap-in support fitting (50) having a body portion (52) with said retaining means (46) thereof including a flange (54) for engaging the support structure (28) at one extremity of the aperture (48) therein to prevent the support fitting (50) from moving through the aperture (48) and a pair of flexible legs (56) extending toward said flange (54) in a cantilevered fashion from said body portion (52) and spaced from said flange (54) for moving through the aperture (48) as said support fitting (50) is inserted therein and for engaging the support structure (28) at the other extremity of the aperture (44) for retaining said support fitting (50) therein.
Claim 8
Dependent Claim
61 words
An assembly as set forth in claim 6 wherein said body portion (52) includes a raised portion (58) in the space between said legs (56) and said flange (54) for close positioning to the support structure (28) within the aperture (44) for preventing said body portion (52) from opening to thereby maintain said male and female portions (34, 36) in engagement.
