Wherein operationally the second portion 426 of the pin 400 passes therethrough the keyhole type slot 287 being rotated such that the second portion 426 of the pin 400 is to be slidably engaged to a part A 293 of the first partial shoulder ridge 288 in the second axial position state 255 and the second portion 426 of the pin 400 is slidably engaged to a part B 294 of the first partial shoulder ridge 288 in the first axial position state 250, also see FIGS. 9 and 10.

Method of Use

[0164] Looking at FIGS. 1 to 20, a method is disclosed for using the dead bolt lock apparatus 55 for selectively securing and un-securing the door 65 to a door frame 75, comprising the steps of firstly providing the dead bolt lock apparatus 55 as previously described.

[0165] A second step of placing the twist lock assembly 225 in the first axial position state 250 via inserting the second portion 426 of the pin 400 through the keyhole type slot 287 such that the second portion 426 of the pin 400 slidably engages the part B 294 of the first partial shoulder ridge 288 to operationally rotationally engage the first element 80 secondary end portion 95 and the extension beam 130 second end portion 145 from the lock cylinder 85, see FIGS. 10, 13, and 20.

[0166] A third step of turning 245, 355, 365 the thumb lever 350 manually about the lengthwise axis 150 that turns the extension beam 130 about the lengthwise axis 150 that subsequently causes the bolt extension assembly 175 to engage the door frame 75 thus operationally securing the door 65 to the door frame 75, see FIGS. 3, 18, and 19.

[0167] As an option for the method for using the dead bolt lock apparatus 55, wherein the second placing step is reversed such that the second portion 426 of the pin 400 is selectively rotated and moved axially along the lengthwise axis 150 to be slidably engaged to the part A 293 of the second partial shoulder ridge 291 in the second axial position state 255 via moving manually the thumb lever 350 along the lengthwise axis 150 toward the lock cylinder 85 to disengage the open slot receptacle 180 and the female annular portion 185, thus placing into the second axial position state 255, thus rotationally having the lock cylinder 85 disengaged to the extension beam 130 that is engaged to the bolt extension assembly 175, see FIGS. 9, 12, 18, 19.

Conclusion

[0168] Accordingly, the present invention of a lock apparatus has been described with some degree of particularity directed to the embodiments of the present invention. It should be appreciated, though; that the present invention is defined by the following claims construed in light of the prior art so modifications of the changes may be made to the exemplary embodiments of the present invention without departing from the inventive concepts contained therein.
