Abstract
Apparatus for securing against removal of the hinge pin of a door or other closure. The arrangement comprises an inner sleeve with holes to align with a hole in the hinge pin to accomodate a holding pin. An outer cylinder encloses the inner sleeve to prevent the escape of the holding pin. A wafer lock has a body which extends through the outer cylinder into the inner sleeve which is provided with internal notches or grooves. Removal of the key causes wafers to extend form the key body to grip the notches or grooves thereby preventing removal of the hinge pin from the hinge. Other embodiments of the inner sleeve fascilitate its use.
Claims17
Apparatus for securing the exposed end of a hinge pin to prevent retraction of said pin, said pin including a hole along a diameter of said pin adjacent said exposed end, comprising:
- a. inner sleeve means for enclosing said exposed end and including openings aligned with said hole to accomodate a holding pin means to engage said sleeve means with said pin;
- b. outer cylinder means to enclose said inner sleeve means to prevent said holding pin from being removed;
- c. lock means for insertion through said outer cylinder means and extending into the interior of said inner sleeve means;
- and
- d. key means for causing expansion of gripping means out of said lock means to engage said inner sleeve means to prevent removal of the latter from said hinge pin thereby maintaining said holding pin means in place and securing said hinge pin.
Apparatus for securing the exposed end of a hinge pin to prevent retraction of said pin, said pin including a pair of openings along a diameter of said pin at right angles to each other adjacent said exposed end, comprising:
- a. inner sleeve means for enclosing said exposed end and including openings aligned with said openings to accommodate holding pin means to engage said sleeve means with said pin;
- b. outer cylinder means to enclose said inner sleeve means to prevent said holding pins from being removed from said openings;
- c. lock means for insertion through said outer cylinder means and extending into the interior of said inner sleeve means;
- and
- d. key means for causing expansion of gripping means out of said lock means to engage said inner sleeve means to prevent removal of the latter from said hinge pin thereby maintaining said holding pin means in place and securing said hinge pin.
A method for securing the exposed end of a hinge pin to prevent retraction of said pin, said pin including a hole along a diameter of said pin adjacent said exposed end, comprising the steps of inserting inner sleeve means over the end of said pin, said inner sleeve means including openings aligned with said hole to accommodate a holding pin means to engage said sleeve means with said pin inserting an outer cylinder means over said inner sleeve means to prevent said holding pin from being removed, and lock means containing key means through said outer cylinder means into the interior of said inner sleeve means, and removing said key means for causing expansion of gripping means out of said lock means to engage said inner sleeve means to prevent removal of the latter from said hinge pin thereby maintaining said holding pin means in place and securing said hinge pin.
