Abstract
Abstract Door locking means comprising a door for closing an opening surrounded by a frame that has a channel extending from top to bottom of one side, the door being hingedly connected to the side of the frame opposite said channel side, and being non-pivotally movable relatively to the frame in the direction of the door width to move the door into and out of the frame channel. Each of the hinges comprises a pin and a journal in which the pin has pivotal movement when the door has been withdrawn from the channel and in which the pin also is laterally movable to permit non-pivotal movement of the door into and out of the frame channel. Lockable means which may be a cam plate bears on the door edge opposite the frame channel to move the door into the channel. The cam may be provided with a key-operated lock cooperating with means on the frame for retaining the door in the channel and preventing movement of the door from either side. The doors embodying the invention may be house, cabinet or other type doors.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
135 words
Door locking means comprising a. a door frame surrounding an opening closed by a door, said frame having a vertically extending channel on one side, b. a door non-pivotally movable relatively to the frame in the direction of the door width into and out of said frame channel at one vertical edge of the door, c. hinges connecting the other vertical edge of the door to the frame, each hinge comprising a pin and a journal in which the pin has pivotal movement when the door has been withdrawn from the channel and in which the pin also is transversely movable to permit non-pivotal movement of the door into and out of the frame channel, and d. lockable means bearing on the door edge opposite the frame channel to move said door into the channel.
Claim 2
Dependent Claim
135 words
Door locking means comprising a. a door frame surrounding an opening closed by a door, said frame having a vertically extending channel on one side, b. a door non-pivotally movable relatively to the frame in the direction of the door width into and out of said frame channel at one vertical edge of the door, c. hinges connecting the other vertical edge of the door to the frame, each hinge comprising a pin and a journal in which the pin has pivotal movement when the door has been withdrawn from the channel and in which the pin also is transversely movable to permit non-pivotal movement of the door into and out of the frame channel, and d. lockable means bearing on the door edge opposite the frame channel to move said door into the channel.
Claim 3
Dependent Claim
34 words
The door locking means defined by claim 1, in which the frame channel has surfaces which face the door edge and the door sides adjacent said edge from top to bottom of said door.
Claim 4
Dependent Claim
77 words
The door locking means defined by claim 1, in which the hinge journals surround an opening circular in cross section communicating with an opening between two parallel sides spaced apart to receive the hinge pin and permit movement of the pin into the circular part of the opening for pivotal movement relatively to the journal, and to permit lateral movement of the pin out of the circular part for movement with the door toward the frame channel.
Claim 5
Dependent Claim
50 words
The door locking means defined by claim 3, in which the surfaces of the circular opening in the hinge journals merge into the parallel sides of said opening by a curved surface which prevents binding of the hinge pin in the journal when the pin moves laterally in the opening.
Claim 6
Dependent Claim
84 words
The door locking means defined by claim 1, in which each hinge comprises a door attachment plate integral with a thickened body portion at one edge of the plate, a pin extending upwardly from said body and a pin extending downwardly from said body, and each hinge comprises a frame attachment plate integral with a pair of vertically spaced journals for reception of the pins of the door attachment plate, said body portion of the door attachment plate fitting between the vertically spaced journals.
Claim 7
Dependent Claim
41 words
The door locking means defined by claim 1, in which the lockable means bearing on the door edge opposite the frame channel comprises a cam plate pivotally attached to the frame and movable into and out of door edge bearing position.
Claim 8
Dependent Claim
24 words
The door locking means defined by claim 6, in which the cam plate is provided with a handle for pivotally moving said cam plate.
Claim 9
Dependent Claim
33 words
The door locking means defined by claim 6, in which the cam plate and the door frame are provided with cooperating key-locked means for locking the cam in its door edge bearing position.
Claim 10
Dependent Claim
33 words
The door locking means defined by claim 1, which includes means mounted in the frame and movable through the frame channel into door bearing position for moving the door out of the channel.
Claim 11
Dependent Claim
42 words
The door locking means defined by claim 1, which includes a shelf-like projection that extends from the door frame into the door opening if the door bottom edge is spaced from the floor or sill, for supporting the door to prevent sagging.
Claim 12
Dependent Claim
190 words
Door locking means comprising a. a door frame surrounding an opening closed by a door, said frame having a vertically extending channel on one side, b. a door non-pivotally movable relatively to the frame in the direction of the door width into and out of said frame channel at one vertical edge of the door, c. hinges connected to the door and to the frame connecting the door at its top and bottom edges to the frame, each hinge comprising a plate fastened to either the top or bottom of the frame and a pin extending from the door into one of said plates, each of said plates having an opening consisting of a circular area and a parallel sided area through which the pin can move into and out of the circular area, said pin having pivotal movement in the circular opening when the door is moved out of the channel and is transversely movable to permit non-pivotal movement of the door into and out of the frame channel, and d. lockable means bearing on the door edge opposite thE frame channel to move said door into the channel.
Claim 13
Dependent Claim
190 words
Door locking means comprising a. a door frame surrounding an opening closed by a door, said frame having a vertically extending channel on one side, b. a door non-pivotally movable relatively to the frame in the direction of the door width into and out of said frame channel at one vertical edge of the door, c. hinges connected to the door and to the frame connecting the door at its top and bottom edges to the frame, each hinge comprising a plate fastened to either the top or bottom of the frame and a pin extending from the door into one of said plates, each of said plates having an opening consisting of a circular area and a parallel sided area through which the pin can move into and out of the circular area, said pin having pivotal movement in the circular opening when the door is moved out of the channel and is transversely movable to permit non-pivotal movement of the door into and out of the frame channel, and d. lockable means bearing on the door edge opposite thE frame channel to move said door into the channel.
