Abstract:
An elongate base for a patient supporting platform, comprising;a frame; first and second hydraulic jacks mounted at spaced apart locations on said frame adjacent opposite ends thereof, each of said first and second hydraulic jacks being configured to connect to said patient supporting platform for effecting a lifting and lowering of said patient supporting platform relative to said frame, said first and second hydraulic jacks each having a reciprocal input mechanism for effecting when reciprocated a lifting of the respective end of the patient supporting platform, each said reciprocal input mechanism having a first part of a two part releasable connection thereon; a manually operable member and a mount for mounting said manually operable member for reciprocal movement relative to said frame; a first linkage member having thereon a pair of longitudinally spaced second parts of each of said two part releasable connections, each said second part being releasably connected to a respective one of said first parts to effect a connecting of said manually operable member to each of said input mechanisms, said first linkage member being configured to convert the reciprocal movement of said manually operable member to a reciprocal movement of said first linkage member to effect a simultaneous lifting of said patient supporting platform in response to the reciprocal movement of said first linkage member; wherein each said first part is an elongate rod having a first section of a first diameter, said first section having an annular groove therein defining a second section of a second diameter less than said first diameter; wherein each said second part is a plate connected to said first linkage member and having a two sector opening therethrough, a first sector of said opening being configured for reception of said first section of said elongate rod therethrough so as to facilitate installation and removal of said first linkage member, said second sector of said opening being smaller in size than said first sector and being configured to receive therein only said second section of said elongate rod so as to facilitate a securement of said first linkage member to each of said reciprocal input mechanisms to thereby facilitate simultaneous operation of said reciprocal input mechanisms in response to reciprocal movement of said first linkage member.
