Abstract
Abstract A monocontrol mechanism for magnetic tape recorders wherein a lever is movable lengthwise and is pivotable in a universal joint which is mounted in a sealed housing. The lever can be depressed by hand against the opposition of a spring to thereby disengage a portion thereof from the locking device in the housing and to be thereupon pivotable between a number of predetermined positions against the opposition of an indexing device which is designed to yieldably hold the lever in any selected predetermined position. Once the pressure upon the lever is terminated, the spring is free to expand and reengages the lever with the locking device. The lever can actuate one or more electric switches, gears, links and/or other controlled units in the housing during movement to or from the predetermined positions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
205 words
In a structure of the character indicated, such as a magnetic tape recorder, a combination comprising a support; an elongated control member; a joint installed in said support and mounting said control member for pivotal movement between a plurality of predetermined positions and for lengthwise movement between first and second positions, said control member being movable lengthwise in each of said predetermined positions; biasing means for urging said control member to said first position; locking means including a first portion provided in said support and a second portion provided on said control member and arranged to engage said first portion in said first position of said control member so as to hold the latter against movement between said predetermined positions; indexing means including a first section provided in said support and a second section provided on said control member and cooperating with Said first section to yieldably oppose the movements of said control member between said predetermined positions, at least in said second position of said control member and to locate said control member in the selected predetermined position thereof; and at least one controlled unit actuatable by said control member in response to movement of said control member to one of said predetermined positions.
Claim 2
Dependent Claim
205 words
In a structure of the character indicated, such as a magnetic tape recorder, a combination comprising a support; an elongated control member; a joint installed in said support and mounting said control member for pivotal movement between a plurality of predetermined positions and for lengthwise movement between first and second positions, said control member being movable lengthwise in each of said predetermined positions; biasing means for urging said control member to said first position; locking means including a first portion provided in said support and a second portion provided on said control member and arranged to engage said first portion in said first position of said control member so as to hold the latter against movement between said predetermined positions; indexing means including a first section provided in said support and a second section provided on said control member and cooperating with Said first section to yieldably oppose the movements of said control member between said predetermined positions, at least in said second position of said control member and to locate said control member in the selected predetermined position thereof; and at least one controlled unit actuatable by said control member in response to movement of said control member to one of said predetermined positions.
Claim 3
Dependent Claim

A combination as defined in claim 1, wherein said support is a housing and said control member is a lever having a first portion located within said housing and including said second portion of said locking means and said second section of said indexing means, said lever further having a second portion which extends from said housing and is accessible for manual movement of said lever from said first to said second position against the opposition of said biasing means and thereupon between said predetermined positions against the opposition of said indexing means.
Claim 4
Dependent Claim
15 words
A combination as defined in claim 1, wherein said controlled unit is an electric switch.
Claim 5
Dependent Claim
41 words
A combination as defined in claim 1, further comprising motion transmitting means interposed between said control member and said controlled unit and arranged to actuate said controlled unit in response to movement of said control member to said one predetermined position.
Claim 6
Dependent Claim
14 words
A combination as defined in claim 1, wherein said joint is a universal joint.
Claim 7
Dependent Claim
78 words
A combination as defined in claim 1, wherein said first section of said indexing means comprises a plurality of rollers and resilient means for biasing said rollers toward each other, said second section of said indexing means including a homing portion provided on said control member and arranged to move between a pair of said rollers against the opposition of said resilient means in response to pivotal movement of said control member to or from a predetermined position.
Claim 8
Dependent Claim
67 words
A combination as defined in claim 1, wherein said first section of said indexing means comprises a face cam and said second section of said indexing means comprises a follower which tracks said face cam during pivotal movement of said control member between said predetermined positions, said first section further comprising means for biasing said face cam against said follower in all positions of said control member.
Claim 9
Dependent Claim
67 words
A combination as defined in claim 1, wherein said first portion of said locking means comprises a plurality of cavities one for each of said predetermined positions of said control member, and said second portion of said locking means comprises a locking element which extends into the corresponding cavity in each predetermined position of said control member and while said control member assumes said first position thereof.
Claim 10
Dependent Claim
59 words
A combination as defined in claim 1, wherein said first portion of said locking means comprises a plurality of projections and said second portion of said locking means comprises a cupped element which receives selected projections of said first portion in each of said predetermined positions of said locking member and while said locking member assumes said first position.
Claim 11
Dependent Claim
36 words
A combination as defined in claim 1, wherein said predetermined positions include a neutral position and a plurality of additional positions, said locking member being pivotable between said additional positions by moving through said neutral position.
