The invention relates to disappearing door structures, and is particularly adapted to be embodied in a safe, or the like, wherein the door disappears or recedes into a space provided adjacent a side wall thereof.
One form of the invention is embodied in a safe having a door and disengageable pivot connections'between the safe and door about which the door swings in its initial opening and final closing movements. During the major portions of its opening and closing movements, the door swings around the pivotal axes of a double hinge secured to the door` and to a carrier which is mounted in avrunway extending parallel with and adjacent one side wall of the safe, the construction being such that the door is swung from its closed position around the disengageable pivot connections and the pivotal axes of the double hinge into a position wherein it is parallel to the side of the safe along which the runway extends. The door is then locked against movement relative to the carrier and pushed with it along the runway until the door does not roject beyond the front wall of the safe. n auxiliary closure member pivoted to an extension of the door closes the front end of the runway when the door is in its closed position and is so constructed and mounted that it prevents one from inserting ones hands into said runway in such manner that ones lingers will be injured or .cut olf between the door and parts of the runway.
may be provided with interlocking tongues and grooves whenv the safe is to be re and heat resisting.

Each spring 73 reacts with the base of its socket and the carrier member or mullion 72 so that it tends to rotate the intermediate bar 70 in a clockwise direction (Figs. 5 and 5a) around the pivotal axis. 71. The bar 70 may rotate in this direction until a surface 70d provided upon it engages the carrier member or mullion 72 (Figs. 2 and 5).
The intermediate bar 70 has a bar 70a secured to it by screws 70b and the bar 7 0a is ivoted at 76 to a hinge member 70" fixed to the plate 33a (Fig. 5a) Y As stated above, the hinge'or cam guide pins 48 extend vertically and are located in the positions which would be occupied by the hinge pins for usually hinging the door shell 30 upon the door` frame 15.
The operation of the improved apparatusA stood that the door will first swing on the pins `48 until the door is disengaged from the tongues and grooves in the 'door frame 15 and until the surface 7 0d on the intermediate bar y abuts against the carriage member or mullion 72. This engagement of the mullion by the surface 7 0d limits further angular displacement of the pivotal axis 7 6 around the axis 71 and thus prevents further movement of the door around the pins 48. The door then swings on the axis 76 untilthe plate 33a engages the mullion 72, whereupon the dopr swings around both of the axes 76 and 71'until it is in the position wherein it is shown in Figs. 3 and 5 and may be pushed back into the guide frame 21. Vhen the door is pushed back into the guide frame, the latch 40 loc'ks it to the carriage 26 so that it can not be displaced around its pivotal axes 71 and 76.
When the door is closed subsequently the hinge means 35, the cam slotted bracket 50 and the pins 48 operate in the reverse manner.
While we have shown and described certain embodiments of our invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is ourintention to claim all novelty inherent in our invention as broadly as possible, inview of the prior art.
