Definitions

  • the invention relates to a locking device for preventing the reopening of a door opening after the closing of a door that previously released the door opening, the wing automatically locked in its position before the release by means of a releasable locking device, with either in a working position or an ineffective position bringable, switchable locking member.
  • a wing is known from FR-A-1 489 150. It is built in a rotatably mounted door, and its locking device consists in a known manner of a spring-loaded lock latch on the door and a cooperating striking plate on the fixed frame. If you close such a door or if it is slammed shut, for example by wind pressure, it can only be opened again by manually operating the lock latch. The latter is done with the help of a rotary handle or a rotary knob.
  • this wing is now equipped with a locking device with a switchable locking element, as proposed by FR-A-1 489 150, the locking device can be overridden if necessary. This is useful if you have to step through the door with the relevant locking and locking device several times in a short time.
  • the door can now be brought into the closed position by hand, by wind pressure or in some other way, without the locking device being effective. As a result, it can be opened from the outside at any time.
  • the locking member interacts with the lock latch.
  • this locking device cannot be used.
  • this locking device requires a loading spring. If this fails or breaks, the locking device in the working position is released automatically. If the door is inadvertently closed, it cannot be opened from the outside.
  • the object of the invention is therefore to develop a locking device on a wing with a locking device of the type described above so that a safe functioning is guaranteed and it can be installed in a wing without a lock latch.
  • the locking device is formed on a wing with a releasable locking device according to the preamble of claim 1 in accordance with the characterizing part of this claim.
  • Sliding sashes in particular doors, are equipped in a known manner with a locking device, the spring-loaded bolt of which interacts with a fixed bolt member on the fixed frame in the sliding-closing end movement, to be precise, engages behind it in the closed position.
  • the bolt can be disengaged using the operating handle of the changeover gear. If the locking device is in its release position, the aforementioned spring-loaded latching of the bolt and bolt element occurs when the wing is closed.
  • the sliding sash is transferred from the locking position, possibly via an intermediate position, for example a tilting position, to the ready-to-move position with the aid of the operating handle or change-over gear and at least one drive rod coupled therewith.
  • the tilt position can already be the ready-to-slide position.
  • the locking device is still in its working position, so that the wing cannot be moved yet. Only when the operating handle is turned further can the release position of the locking device be reached, in which its bolt is out of operative connection with its striking plate or the like.
  • the wing can now be moved as desired and pushed back into the starting position without the latching device locking when, according to the invention, in a rotary position of the latter beyond the ready-to-move ready position of the operating handle, the locking member is in the range of movement of the return movement of the drive rod or rods or a related approach or fitting part can be brought.
  • the operating handle Contrary to normal use, in which the operating handle returns to the ready-to-move position or is turned back again after the latching device has been disengaged and a subsequent shifting movement, the operating handle remains in the rotary position beyond the ready-to-move position when the locking device is effective until the Locking device is released again.
  • This particular rotational position of the control handle is easily recognizable optically, so that one can also determine from a distance whether the locking device is in the working or release position.
  • the loading spring of the movable latch of the locking device pushes the actuating element back into the ready-to-slide position or the previous position at the moment in which the return movement of the drive rod is released by the adjustable locking member. If the sliding ready position is reached, for example, by a 90 ° rotation of the actuating member, then a further 30 ° or 45 ° rotation movement can achieve the position in which the locking member can be brought into its working position (FIG. 2) .
  • the locking member does not require a spring, so that this source of failure is switched off.
  • this locking device can be used wherever there is a drive rod with a gearbox anyway.
  • the sash is automatically brought from the locking position, for example via a 90 ° rotation of the operating handle, into the ready-to-slide position, from which it can be moved directly.
  • the wing is in a parallel offset position, for example opposite the wall or an adjacent element in front of which it is to be pushed.
  • there are also sliding leaves that are in the closed position in the same plane as the neighboring element for example a fixed glazed field in front of which they are to be pushed.
  • the sash must be parked in parallel before moving.
  • the parallel parking is preceded by a tilt position.
  • the releasable locking device can block the transition from the tilted position into the ready-to-slide position.
  • the position preceding the ready-to-move position namely the tilting position of the wing, is to be secured or released by the latching device.
  • a second 45 ° creates the transition to the parallel storage position, which is also the ready-to-slide position.
  • the actuating member should allow a rotary movement beyond 90 °.
  • the mode of operation of the locking member and the locking device which can be blocked or released by the locking member, is basically the same as that of the only lockable and sliding wing. If the locking member is to be brought into the working position when the sash is displaced, the operating handle must also be "rotated" beforehand in this case, for example by 30 °, in order to raise the connecting rod or its attachment or the like by the necessary amount. If with ineffective locking member the parallel parked or in a tilt-back standby position, due to an automatic or by its weight or by wind pressure u. Like.
  • the locking device prevents returning to the ready position for sliding and thus an (opening possibility for this wing.
  • the wing may return to the tilt position by itself when the locking member is in the working position, but it can by one external person may be pulled out from below and brought into its parallel storage position, from which one can subsequently shoot it in the opening direction. This prevents the external persons from being locked out. Otherwise, the actuating member is moved further into a position suitable for activating the locking member comparable to depressing a door handle.
  • a particularly preferred embodiment of the invention is characterized by a toothed rack of the adjusting gear which forms or is connected to a sliding link and is connected to the drive rod in a drive connection, the toothed rack being in engagement with a pinion or partial pinion which can be rotated by means of the operating handle.
  • the rack or the sliding member is coupled in a development of the invention with at least one drive rod on the closing side of the wing.
  • the toothed rack or the sliding member carries, for example, at least one coupling bolt or the like, which engages in an opening or in a receptacle of the drive rod.
  • the locking member is designed as a slide which is mounted in the transmission housing and projects outward.
  • the protruding end of the slide forms a handle with which it can be transferred from the ineffective to an effective position and vice versa.
  • the locking member can be locked in its effective and an inactive position. This prevents accidental adjustment, in particular returning to the ineffective position. This would be possible, for example, if the sliding link or the rack is in the active position Locking member is not present, but a small game is available, as can be achieved and drawn in the embodiment of FIG. 2. When the control handle is released, this game is automatically canceled due to spring action.
  • a preferred variant of the invention is characterized in that the locking member can be locked by means of a locking device, in particular a snapper, the two catches of which are located on the gear housing, preferably a rear wall of the housing. Snappers are very robust, reliable and inexpensive locking devices.
  • the drawing shows an embodiment of the invention.
  • an operating handle 2 is rotatably mounted in a gear housing 1 of a door or window fitting for actuating at least one drive rod, not shown, with which the door or the window sash can be locked with respect to a fixed frame or another known changeover position.
  • a toothed segment or partial pinion 4 sits on the axis of rotation 3 of the service handle 2 in a rotationally fixed manner. Its teeth 5 mesh with those 6 of a toothed rack 7.
  • the toothed rack forms a sliding member which can be transferred from the lower sliding position shown in FIG. 1 to the upper sliding position shown in FIG. 2.
  • the teeth of the partial pinion extend over an angle of, for example, approximately 120 °. The entire sliding distance of the rack 7 corresponds to this angle.
  • the rack 7 preferably carries two coupling pins 9 and 10, which in FIG. 2 extend vertically downward from the plane of the image and project beyond the rear wall 8 of the housing on.
  • This opening of the latching device is associated with a tensioning of a return spring, in particular the latching device, which on the one hand automatically brings the latching device back into its latching position and on the other hand returns the operating handle 2 to its horizontal 90 ° rotational position (not shown). If, starting from the position of the operating handle according to FIG. 2, the door is moved in the opening direction in the direction of arrow 13 and then, or after a short displacement distance, the operating handle is released, the reset is of course also carried out, but then the two parts the locking device so far apart that locking is no longer possible. If, however, the door is subsequently returned to the sliding closed position counter to arrow 13, the latching device automatically comes into operation when the operating handle is in a horizontal position. It is then no longer possible to open the slide again. The door can only be pushed open again if the locking device is again overridden in the manner described.
  • the adjustable locking member 14 built into the gear housing 1 according to the invention can be moved from its ineffective position shown in FIG. 1 into its effective working position shown in FIG. 2 convict.
  • its upper end 15 is located directly or at a short distance below the lower end 16 of the rack 7, i.e. in the downward movement range of the rack 7.
  • a downward movement of the rack 7 is at most by the in Fig. 2 drawn game, but not possible by an amount necessary for the locking device to take effect. Therefore, when the door is closed by sliding, the locking device cannot come into effect when the door has reached the closed position. It is thus possible for the door to be pushed back into the closed position from the outside and, in the absence of an external operating handle, to be returned to the open position from the outside can be brought.
  • the rack 7 or a corresponding or coupled element must be such be designed so that in the slightly over the tilt position (z. B. 30 °) position of the fitting "sliding" of the locking member 14 is possible in the same way as with the fitting shown in the drawing, which only one locking and one Readiness for sliding provision.
  • a locking device which consists of a cutter housed in the locking member 14, consisting of a compression spring 17 and a cutter body 18, and two in the sliding direction of the locking member 14 on the rear wall 8 of the gear housing located catches 19 and 20 is constructed.
  • the distance between the two catches corresponds to the displacement distance of the locking member 14 from the ineffective to the active position.
  • the lower end of the locking member 14 in the drawing is guided through a corresponding opening of the gear housing 1 to the outside and forms a handle 21 for adjustment.
