Definitions

  • This door lock comprises an elongate. locking rod that is mounted in one side of the door frame to engage in an elongate recess in the side of the door opposite the door hinge.
  • This locking rod is constantly urged by springs into engagement with the recess and is held in engagement with the recess by a second. operating rod that is mounted in the door frame alongside the locking rod but at the opposite side thereof from the recess.
  • the operating rod is cylindrical for the major part of its periphery but has an elongate recess in it around part of its periphery.
  • a spring-pressed pin on a rotary lock member can lock the operating rod in locking engagement with the locking rod.
  • a second pin eccentrically mounted in this same lock member to engage in a second elongate recess in the operating member can rotate the operating member to and from locking engagement with the locking mem ber.
  • This invention relates to a device for locking a door or the like which on one side is part-rotatable about an axle in a surrounding frame or case.
  • the invention has for its main object to provide a device of this kind which is practically completely safe against burglary due to a locking effect being produced over the entire or at least major part of the longitudinal extension of the door.
  • Another object of the invention is to provide a locking device which is located to the door frame instead of the door proper which results in that the latter can be simplified considerably and the locking mechanism as a whole be made more effective.
  • FIG. 1 is a perspective view of a door frame and a door with an edge portion of the door cut away for clearer illustration;
  • FIG. 2 is a perspective view of an upper portion of the locking device on a larger scale and with portions of the door frame cut away;
  • FIGS. 3 and 4 show horizontal sections through the locking device in two different positions, said sections being taken in downward direction above a rotatable knob mounted on the frame;
  • FIG. 5 is a perspective view of a portion of the locking device surrounding the rotatable knob, the front portion of the door frame being removed;
  • FIG. 6 is a top view of the frame and the door adjacent the axle or so-called lifting hinge of the door.
  • reference numeral 10 generally denotes a rectangular door frame which is mounted in a door opening and which comprises two vertical frame pieces 12, I4, an upper frame piece 16 and a lower frame piece or door step 18. Suspended in the frame which may be made of metal, plastic or other suitable material is a door 20. This is supported by a shaft or axle 22 extending adjacent the vertical frame piece 12 and having its center line preferably located in the central plane of the door panel 20. The cylindrical shaft 22 is rigidly united with the door by means of transversal screws 23 (FIG. 6) or similar fastening means.
  • the axle has at both ends an extension having the shape of a central dowel 24 extending into the upper or lower frame piece l6, 18, respectively, of the frame in which pieces each dowel is mounted in a bearing such as a ball bearing 26.
  • the lower one of these bearings carries also the axial load from the door.
  • the frame piece 12 is formed with a step 28 fitting the edge of the door when the door is turned from closed position. indicated by full lines, to open position indicated by dash and dotted lines, as shown in FIG. 6.
  • the locking device according to the invention is mounted to the opposite vertical side of the door frame.
  • the frame piece I4 has a generally U- shaped profile open towards the door opening, an elongated ope rating member 30 with its both ends rotatably mounted by means of dowels 32 in projections 34 rigidly united to, or formed in one piece with, the frame.
  • the operating member 30 extends over practically the entire vertical longitudinal side of the frame and has a cylindrical shape with the exception of a recess 36 which suitably occupies one quadrant or a similar portion.
  • the operating member 30 is actuated from outside by means of a knob 38 (FIGS. 1 and S) rotatably mounted in the frame piece 14 and preferably located at that side of the door which faces the room.
  • the knob 38 has an eccentrically located pin 40 adapted to cooperate with a recess 42 (FIG. 5) formed in the operating member 30 so that when the knob 38 is turned clockwise the operating member is caused to rotate counterclockwise according to FIG. 3 over about one eighth of a revolution.
  • the operating member 30 can be locked against rotation in both its operative positions by means of a pin 43 which is mounted centrally within and axialiy displaceable inside the knob 38.
  • a locking member Arranged outside the operating member 30 and in parallel relationship therewith is a locking member having the shape of a cylindrical roll or rod 44 (FIGS. 4 and 5) rotatably mounted on a central pivot rod 46.
  • This pivot rod extends into each of the horizontal frame pieces 16, 18 where it is'rigidly united with a transversely extending pin 48 (FIG. 2).
  • Each pin 48 is slidably mounted in a horizontal groove 50 in the frame pieces 16 and 18, respectively.
  • the roll or rod 44 is rotatable about the pivot 46 extending from the top of the frame to the bottom with the transverse pins 48.
  • the operating member 30 on each of its ends is .devised to cooperate with a torsion spring 52 (FIG. 2) which tends to rotate the member clockwise from the position shown in FIG. 4 to that shown in FIG. 3.
  • the locking member 44 is at its ends under the actuation of springs 54 which tend to displace the member towards the left from the position shown in FIG. 4 to that shown in FIG. 3 in which latter position the member is in engagement with a longitudinal recess or groove 56 is formed in the adjacent narrow side of the door.
  • This recess or groove is located symmetrically to the central plane of the door and has two suitably plane lateral surfaces 58, 60 which are so inclined to one another that the width of the recess diminishes towards the bottom of the recess.
  • the pin 43 To open the door the pin 43 must, to begin with, be drawn out and thereafter the knob 38 rotated so that the operating member passes from the position accord ing to FIG. 3 to the position according to FIG. 4.
  • the recess 36 has now been displaced to a position that is symmetrical relative to the locking member 44 so that this member can be withdrawn from the engagement with the recess 56in the door.
  • the springs 54 continue to force the roll 44 into engagement with the recess 56 in the door, but as their power exercises a minor load only on the door, said spring power can be mastered so that the door can be opened.
  • the locking member 44 now performs a rolling movement along the inclined surface 58 and along the door edge portion 64 adjacent the recess 56, said locking member by parallel displacement being caused to enter the recess 36 of the operating member as is understood from FIG. 4.
  • the locking member or roll 44 is automatically returned to its outer end position due to actuation by the springs 54, and the operating rod 30 due to actuation by the torsion springs 52 is rotated back to the position according to H6. 3. Then the roll 44 is locked again so that the door cannot be closed unless the pin 40 forces the operating mem ber 30 into the position according to FIG. 4. Thus the locking device of the door cannot be caught unintentionally. However, if desired, the operating member 30 can be blocked in the position shown in FIG. 4 by insertion of the pin 43 of the knob 38 into the recess 42 so that the locking roll 44 thus without any obstacle can be forced into the door recess 56 for closing and opening the door.
  • a lock 66 (FIG. 1) is provided which may consist of a key-actuated bolt of known kind adapted for cooperation with the operating member 30. Since the door is to be opened inwards no particular handle is required on the exterior side.
  • the locking device and the door are highly burglaryproof since the door is blocked at its free narrow side over a very long portion.
  • the so-called lifting hinge as a shaft extending from end to end in a centre plane of the door, the door cannot be removed by lifting it from the hinge or hinges.
  • the locking member 44 must not have a continuously coherent cylindrical surface cooperating with the recess in the door, but may be composed of a plurality of coaxial cylinder bolts in mutually spaced relationship which are displaceable in parallel from a locking position to a releasing position as described above and which then may be mounted on a common pivot rod 46.
  • a lock for a door which is hingeable in a door frame about an axle mounted in one side of the frame, comprising two elongate members mounted in the opposite side of the door frame in parallelism to said axle, one of which is an operating member that is rotatable about an axis parallel to the axis of said axle, and the other of which is a locking member reciprocable in a direction transverse to said axes for movement from an open position, in which it is engaged with an elongate recess in said operating member that extends parallel to said axes, into a locking position in engagement with an elongate recess in the free adjacent edge of the door that extends parallel to said axes, and vice versa.
  • a lock as claimed in claim 1 wherein a spring is connected to said operating member and constantly urges said operating member rotatably into a position in which the recess in said operating member will register with said locking member.
  • a lock as claimed in claim 1 wherein an actuating member is rotatably mounted in the door frame to rotate on an axis at right angles to the axis of rotation of said operating member, and a pin is reciprocably mounted in said actuating member for movement transversely to and from engagement with the recess in said operating member, and is adapted when engaged with the last-named recess to lock said operating member in locking engagement with said locking rod.
