Support device with floating pins bag
First Claim
1. A method of operating a device comprising the steps of:
- a. extending a pin through a spring carried by said device, b. placing said spring in a release mode, so that said pin fits loosely in said spring and thereby allows pin movement, by applying a flexing force to at least one end coil of said spring to increase a diameter of said spring, c. moving said pin outward from said device so that a first end of said pin may interact with an object, and d. placing said spring in locking mode, so that said pin is held tightly by said spring and thereby restrains pin movement, by relaxing said flexing force on said end coil, wherein any said pin-object interaction selectively inhibits object movement.

Abstract
A device particularly adapted to engage an irregular bottom surface of an object and then carry that object includes a support block. In the support block is a set of longitudinally spaced apart upright bores. On each side of the bores in a top wall of the block is a guide channel for a slide bar. Ends of these bars operatively connect with a reciprocating mechanism attached to one end of the block. In each bore is a sleeve having an inner opening formed with an upper section for a spring. An upper and lower end coil of a coil portion of each spring connects with an arm that projects outwardly. The upper arms fit respectively in upward facing slots in one slide bar while the lower arms fit respectively in downward facing slots in the other slide bar. In the sleeve inner openings and extending respectively through the coil portion of each springs is a support pin. Top ends of these pins fit in openings in a top cover plate fastened to the support block top wall. A bottom end of each pin then seats on one end of a transversely positioned conduit in a top surface of a bottom cover plate fastened to a bottom wall of the support block. Opposite ends of these conduits connect with a distribution channel in the block bottom wall. For use, the device distribution channel is connected to an air supply. At the same time, the reciprocating mechanism is activated to move the slide bars and rotate the end coils of the springs. Movement of the end coils transfers to the remaining coils of each spring to increase a diameter of each spring coil portion and shift each spring from a locking mode to a release mode. Air from the distribution channel then floats the pins upward to selectively engage the bottom surface of the object above. The reciprocating device then is deactivated allowing the springs to return to a locking mode about the pins.

3. A method of operating a device particularly adapted to support an object located above said device, said method comprising the steps of:
-
a. locating a spring in a release mode in a vertical bore of a support block of said device and applying a force to at least one end coil of said spring to increase a diameter of said spring to place said spring in said release mode, b. extending a pin through said spring, c. moving said pin upward until said pin engages said object, d. securing said engaging location of said pin by placing said spring in a locking mode, and step a. further including operatively connecting an arm attached to said spring end coil to a slide bar carried by said support block, and e. moving said slide bar, wherein, with said pin locked in place, said pin supports said object.

4. A method of operating a device particularly adapted to support an object located above said device, said method comprising the steps of:
-
a. locating a spring in a release mode in a vertical bore of a support block of said device, b. extending a pin through said spring, c. moving said pin upward until said pin engages said object, d. securing said engaging location of said pin by placing said spring in a locking mode by applying a force to at least one end coil of said spring to decrease a diameter of said spring to place said spring in a locking mode, and step d. further including operatively connecting an arm attached to said spring end coil to a slide bar carried by said support block, and e. moving said slide bar, wherein, with said pin locked in place, said pin supports said object.

5. A method for supporting an object, said method comprising the steps of:
-
a. locating a spring in a bore of a support block, b. loosely extending a pin through said spring, c. moving said pin upward to engage said object with an outer end of said pin by applying a force to an inner end of said pin, d. maintaining said pin-object engagement by placing said spring in a locking mode by applying a rotational force to at least one end coil of said spring to decrease a diameter of said spring, and step a. including said support block having a set of spaced apart bores with said bores carrying respective springs and pins, and step d. including operatively connecting arms attached respectively to said spring end coils to a slide bar carried by said block, and e. moving said slide bar.

6. A method of operating a device comprising the steps of:
-
a. placing a pin inside a spring carried by said device so that a first end of said pin extends outward from said spring for engagement with an object, b. placing said spring in a locking mode, so that said pin is held tightly in place by said spring, by applying a flexing force to at least one end coil of said spring to reduce a diameter of said spring, c. placing said spring in a release mode, so that said pin is held loosely by said spring, by relaxing said flexing force on said spring end coil, and d. moving said pin toward said spring to separate said pin from said object, wherein any said pin-object engagement with said spring in said locking mode selectively inhibits object movement.
