Baseframe With Attachment

Abstract

An articulating support arm, an articulating support arm and baseframe in combination and a method of installing an articulating support arm on a baseframe are described. The baseframe and the support arm have corresponding interlocks thereon. The interlocks can be engaged or disengaged by appropriately bringing the support arm into contact with the baseframe. When the interlocks are engaged with one another, the support arm is held in position by the interlocks to allow fasteners to be inserted to lock the support arm and baseframe together and prevent the interlocks from disengaging.

I claim: 
     
         1 . An articulating support arm for adjustably supporting an object at a workstation, said arm comprising a base connected directly or indirectly to said workstation, an elongated member and a platform, said elongated member having an inner end and an outer end, said inner end of said elongated member being pivotally connected to said base, said outer end of said elongated member being pivotally connected to said platform said platform being capable of supporting said peripheral thereon, said platform being adjustable to various lockable and releasable positions relative to said base, said base having an inner portion and an outer portion, said outer portion having releasable interlocks thereon, said interlocks corresponding to interlocks on a plate of a baseframe, said interlocks being engageable and releasable by appropriately moving said base and said plate into and out of contact with one another, said support arm having one or more releasable locking mechanisms to lock said platform in a particular position, to unlock said platform for movement to a different position relative to said base and relocking said platform relative to said base, said interlocks being sufficiently secure to hold said base against said plate before any fasteners are used in addition to the interlocks, said base being substantially parallel to said plate when said interlocks are engaged with one another before any fasteners are connected in addition to said interlocks.

         7 . A support arm as claimed in  claim 3  wherein said interlocks engage one another when said projections are located within said loops. 
     
     
         8 . A support arm as claimed in  claim 2  wherein said fasteners are screws that affix said base to said plate after said interlocks are engaged. 
     
     
         9 . A support arm as claimed in  claim 6  wherein said fasteners are screws that affix said base to said plate when said interlocks are engaged, said screws extending through openings located at or near an inner edge of said base and said plate. 
     
     
         10 . A support arm as claimed in  claim 1  wherein there are two interlocks on said plate that are shaped to engage with two corresponding interlocks on said base. 
     
     
         11 . An articulating support arm for use with a baseframe having a movable plate therein, said support arm having a base, said baseframe comprising an elongated body with channels along each side, said plate and said base having corresponding interlocks thereon, said interlocks being shaped to releasably interlock with one another when said arm is appropriately brought into contact with said baseframe. 
     
     
         12 . A baseframe and articulating support arm in combination, said baseframe being mounted beneath a working surface at a workstation, said combination comprising said baseframe having a movable plate that is sized and shaped to be connected to a base of said support arm, said support arm having at least one pivotally connected elongated member with a platform at a free end opposite to said base, said plate having interlocks thereon corresponding to interlocks on said base, said interlocks being sized and shaped to releasably engage one another when said base is moved into contact with said plate, with one or more fasteners to lock said base to said plate after said interlocks engage one another. 
     
     
         13 . A baseframe and articulating support arm in combination, said baseframe being mounted beneath a working surface at a workstation, said combination comprising said baseframe having a movable plate that is sized and shaped to be connected to a base of said support arm, said support arm having at least two pivotally connected elongated members with a platform at a free end opposite to said base, said plate having interlocks thereon corresponding to interlocks on said base, said interlocks being sized and shaped to releasably engage one another without fasteners when said base is appropriately moved into contact with said plate, said base being substantially parallel to said plate when said interlocks of said base and said plate engage one another. 
     
     
         14 . A baseframe and articulating support arm in combination as claimed in  claim 13  wherein half of said interlocks are loops and half of said interlocks are projections that are sized to fit in said loops. 
     
     
         15 . A baseframe and articulating support arm in combination as claimed in  claim 14  wherein said interlocks on said plate are loops and said interlocks on said base are projections. 
     
     
         16 . A baseframe and articulating support arm in combination as claimed in  claim 13  wherein said interlocks are located on an outer portion of said plate and base. 
     
     
         17 . A baseframe for use with an articulating support arm, said baseframe comprising an elongated body with channels along each side, said channels being shaped to support a plate that is movable longitudinally along said baseframe, said articulating arm having a base that is sized and shaped to fit on said plate, said base having releasable interlocks on an outer portion thereof, said releasable interlocks on said base corresponding to said interlocks on said plate, said interlocks being lockable and releasable by appropriately moving said interlocks into and out of contact with one another respectively, said interlocks being sufficiently secure to hold said base against said plate before any fasteners are used in addition to said interlocks, said base being substantially parallel to said plate when said interlocks are engaged with one another before any fasteners are installed. 
     
     
         18 . A method of installing an articulating support arm to an underside of a plate mounted on a baseframe beneath a working surface of a work station, said support arm having a base, said plate and said base having corresponding interlocks thereon, said base and said plate being sized to fit together in contact with one another, said method comprising commencing with said baseframe connected to an underside of said working surface, manually moving said support arm into contact with said plate in such a manner relative to said baseframe that said interlocks interlock with one another through said contact, said interlocks being located so that when said support arm is released after said interlocks are engaged with one another, said base is parallel to and generally aligned with said plate and said support arm remains in that position without any external force being applied to said support arm, subsequently inserting fasteners between said base and said plate to fixedly secure said base on said plate and to prevent said interlocks from disengaging when external forces are applied to said support arm. 
     
     
         19 . A method as claimed in  claim 18  including the steps of removing said fasteners and disengaging said interlocks by moving said support arm away from said baseframe. 
     
     
         20 . A method of connecting an articulating support arm to an underside of a plate mounted on a baseframe beneath a working surface of a workstation, said plate having two first interlocks thereon, said support arm having an attachment surface with two second interlocks thereon, said second interlocks corresponding to said first interlocks, there being at least one fastener, said method comprising manually placing said attachment surface in contact with said plate in such a manner as to cause said interlocks to engage with one another, said arm being fully supported by said plate when said interlocks are engaged with one another, installing at least one fastener to cause said attachment surface to be securely mounted on said plate, and installing fasteners to lock said attachment surface on said plate.
