Abstract:
A manual emergency tool assembly comprising:A. a first operating head having a first handle extending therefrom, said first handle having a cylindrical shape, i. a first semicircular notch being formed therein adjacent to said first operating head, ii. a first elongated segmental shaped notch being formed therein on the diametrically opposite side of said first handle from said first semicircular notch, and axially spaced from said first semicircular notch and extending toward the free end of said first handle, iii. a circumferentially extending semicircular notch being formed therein at the end of said first elongated segmental shaped notch closer to the free end of said first handle, iv. a second elongated segmental shaped notch being formed therein on same side of said first handle as said first semicircular notch and extending from said circumferentially extending semicircular notch to the free end of said first handle, B. a second operating head having a second handle extending therefrom, said second handle having a cylindrical bore therein for receiving said first handle in a telescopic relationship, a securing arrangement housing attached to the end of said second handle opposite said second operating head, said securing arrangement housing having a cylindrical bore therein for receiving said first handle, a. a rotatable cylindrical locking pin being received in a first bore in said securing arrangement housing, said first bore being perpendicular to and partially intersecting the cylindrical bore in said second handle, said rotatable cylindrical locking pin having a semicircular notch therein which in a first position of said rotatable cylindrical locking pin may be aligned with the cylindrical bore, such that said first handle may be telescopically received and reciprocate in said second handle, with said first semicircular notch aligned with said rotatable cylindrical locking pin, said cylindrical locking pin may be rotated to a second position to face the semicircular notch in said cylindrical locking pin away from said first handle, such that a portion of the locking pin is positioned in said first semicircular notch to secure said first and second handle in a fully telescoped position with respect to each other, b. a fixed locking pin received in a second bore in said securing arrangement housing, said second bore being perpendicular to and partially intersecting the cylindrical bore, such that a portion of said fixed locking pin extends into said cylindrical bore, said second bore being located closer to said second handle than said first bore, and on the diametrically opposite side of said cylindrical bore in said second handle, whereby to insert said first handle in the cylindrical bore in said second handle, said rotatable cylindrical locking pin is rotated to align the semicircular notch therein with the cylindrical bore, and said second elongated segmental shaped notch is aligned with said fixed locking pin, said first handle being inserted until the fixed locking pin is located in the circumferentially extending semicircular notch, the handles being rotated with respect to each other until the fixed locking pin is aligned with the first elongated segmental shaped notch, further inserting said first handle in said second handle until said first semicircular notch is aligned with said rotatable cylindrical locking pin, rotating said cylindrical locking pin to face the semicircular notch in said cylindrical locking pin away from said first handle, such that a portion of the locking pin is positioned in said first semicircular notch to secure said first and second handle in a fully telescoped position with respect to each other.
