Abstract
Abstract A motion transmitting remote control assembly which prevents connection of the outer casing members of adjoining mechanical push-pull control sections unless the inner translating core members are connected. The assembly includes at least two inner translating core members for transmission of motion and being detachably connected for allowing connected and disconnected positions. At least two outer casing members slidably receive the inner translating core members and are detachably attached by a coupling nut for allowing attached and unattached positions. A spring-loaded finger member having a flange portion is pivotally housed in a longitudinal cavity in one of the core members. A head member is connected to the other core member by an extension member. The first-mentioned core member has a slot which terminates in a radial bore adjacent the longitudinal cavity for receiving the extension member and the head member. The finger member has a reactive surface which cooperates with an interaction surface on the head member for moving the finger member to a retracted position when the inner translating core members are connected in order to provide an operable position of the assembly whereby the outer casing members may be connected. Additionally, the second-mentioned inner translating core member engages a shoulder surface defined by its associated outer casing member to limit axial movement of the second core member.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
118 words
A motion transmitting remote control assembly of the type for transmitting longitudinal movement along a curved path and comprising; a flexible motion transmitting means for transmission of motion and having detachable connection means for allowing connected and disconnected positions, outer casing means for slidably receiving said motion transmitting means and having detachable attachment means for allowing attached and unattached positions, and control means having an operable position for permitting said outer casing means to be moved to said attached position only when said motion transmitting means is in said connected position and an inoperable position for preventing said outer casing means from being moved to said attached position when said motion transmitting means is in said unconnected position.
Claim 2
Dependent Claim
118 words
A motion transmitting remote control assembly of the type for transmitting longitudinal movement along a curved path and comprising; a flexible motion transmitting means for transmission of motion and having detachable connection means for allowing connected and disconnected positions, outer casing means for slidably receiving said motion transmitting means and having detachable attachment means for allowing attached and unattached positions, and control means having an operable position for permitting said outer casing means to be moved to said attached position only when said motion transmitting means is in said connected position and an inoperable position for preventing said outer casing means from being moved to said attached position when said motion transmitting means is in said unconnected position.
Claim 3
Dependent Claim
18 words
An assembly as set forth in claim 1 including enclosure means for limiting access to said control means.
Claim 4
Dependent Claim
48 words
An assembly as set forth in claim 1 wherein said control means includes interference means movable between a stored position and an interference position in response to said connected and disconnected positions of said motion transmitting means for providing said operable and inoperable positions of said control means.
Claim 5
Dependent Claim
34 words
An assembly as set forth in claim 3 wherein said control means includes coaction means for moving said interference means to said stored position when said motion transmitting means is in said connected position.
Claim 6
Dependent Claim
25 words
An assembly as set forth in claim 4 wherein said control means further includes biasing means for urging said interference means to said interference position.
Claim 7
Dependent Claim
35 words
An assembly as set forth in claim 5 including abutment means for cooperating with said interference means when said interference means is in said interference position to provide said inoperable position of said control means.
Claim 8
Dependent Claim
33 words
An assembly as set forth in claim 6 wherein said motion transmitting means includes at least two inner translating core members for providing said connected and disconnected positions of said motion transmitting means.
Claim 9
Dependent Claim
27 words
An assembly as set forth in claim 7 including a longitudinal cavity in at least one of said inner translating core members for housing said control means.
Claim 10
Dependent Claim
40 words
An assembly as set forth in claim 8 including motion limiting means for limiting axial movement of a second inner translating core member so that said second core member may cooperate with said control means to provide said inoperable position.
Claim 11
Dependent Claim
95 words
An assembly as set forth in claim 9 wherein said interference means includes a finger member having a flange portion, said finger member and said flange portion being positioned in said longitudinal cavity of said first-mentioned core member and pivotally attached therein to allow movement between protruded and retracted positions relative to said core member for providing said interference and stored positions, said biasing means urging said finger member to said protruded position and said flange portion engageable with said abutment means when said finger member and said flange portion are in said protruded position.
Claim 12
Dependent Claim
32 words
An assembly as set forth in claim 10 wherein said detachable connection means includes a head member and an extension member connecting said head member to said second inner translating core member.
Claim 13
Dependent Claim
115 words
An assembly as set forth in claim 11 wherein said detachable connection means further includes a slot extending radially inwardly from the outer edge of said first-mentioned inner translating core member and terminating in a radial bore adjacent said longitudinal cavity for receiving said head member and said extension member, a collar surface defined by said radial bore in said first-mentioned core member, and a seating surface defined by said head member of said second-mentioned core member adapted to seat on said collar surface of said first-mentioned core member, said connected position includes said head member positioned in said radial bore adjacent said longitudinal cavity and said seating surface being engageable with said collar surface.
