Adjustable carriage holder for support apparatus
A carriage holder for support of an apparatus includes identical upper and lower support plates having on their outer edge a number of indentations corresponding to the number of apparatus to be supported, said indentations providing aligned radial horizontal grasping surfaces on one side of said apparatus. The carriage holder also includes a series of vertical spring pivot pins joining said upper and lower support plates, adjacent to each said indentation, each such pin bearing a torsion spring loaded retractable clamp member to provide grasping surfaces in retracted position opposite to the grasping surfaces of said indentations. The carriage holder also includes an unobstructed aperture in each of said aligned support plates for mounting said carriage holder on a shaft. The carriage holder further includes a locking mechanism to hold said carriage in a fixed position on the shaft.
1. A carriage holder for support of an apparatus comprising:
identical upper and lower support plates having on their outer edge a number of indentations corresponding to the number of apparatus to be supported, said indentations providing aligned radial horizontal grasping surfaces on one side of said carriage holder;
a series of vertical spring pivot pins joining said upper and lower support plates, adjacent to each said indentation, each such pin bearing a torsion spring loaded retractable clamp member to provide grasping surfaces in retracted position opposite to the grasping surfaces of said indentations;
an unobstructed aperture in each of said aligned support plates for mounting said carriage holder on a shaft; and
a locking mechanism to hold said carriage in a fixed position on the shaft.
2. A locking mechanism to hold a platform plate in an adjustable fixed position on a shaft comprising:
a locking lever having a handle and body portion containing an aperture larger than a diameter of the shaft to fit over the shaft, tabs located laterally between said aperture and said handle, and bores on either side of the locking lever aperture through which stabilizing pins are disposed to guide a force mechanism applied in orientation to the locking lever to maintain it in locked position; and
mounting blocks affixed to said platform plate on either side of said locking lever containing bushings to accommodate said tabs of said locking lever thereby providing an axis of rotation to said lever, the locking position occurring when the rim of said aperture is rotated by said force mechanism into a contact engagement zone with the shaft.
3. The carriage holder of claim 1 , wherein said torsion spring is anchored by extension of a spring wire to a loop engaging a stationary post to prevent rotation of the spring.
4. The locking mechanism of claim 2 , wherein the force mechanism comprises one or more of a solenoid, a hydraulic or pneumatically activated piston, and a spring.
5. The locking mechanism of claim 2 , wherein the force mechanism is configured to apply a force to prevent slippage of the locking mechanism given the weight bearing load of the platform, wherein the force does not impede axial rotation of said platform about the shaft.
6. The carriage holder of claim 1 , wherein said locking mechanism comprises:
a locking lever having a handle and body portion containing an aperture larger than a diameter of the shaft to fit over the shaft, tabs located laterally between said aperture and said handle, and bores on either side of the aperture through which stabilizing pins are disposed to guide a force mechanism applied in orientation to the locking lever to maintain it in locked position; and
mounting blocks affixed on either side of said locking lever containing bushings to accommodate said tabs of said locking lever thereby providing an axis of rotation to said lever, the locking position occurring when the rim of said aperture is rotated by said force mechanism into a contact engagement zone with the shaft.
