Definitions

• the invention relates to a sash lock for a door or flap, in particular of control cabinets or the like, with a housing fixed to the door leaf or the flap and with a housing rotatably arranged in the housing, rotatably rigidly connected on the inside of the door leaf with a sash tongue and on the outside of the door leaf with a closing actuation such as handle, cylinder lock or the like actuating shaft which can be coupled, the housing for its attachment to the door leaf having a rosette arranged on the outside of the door leaf and inside the door leaf having an external thread for screwing on a fastening nut until it abuts the door leaf.
• a fastening nut designed as a ring nut is screwed onto the external thread of the housing until it rests against the inside of the door leaf, the rosette serving as an abutment.
• the door leaf is clamped between the rosette and the screwed-on fastening nut and the cam lock is thereby fastened to the door leaf.
• the fastening nut for the assembly of the sash lock on the door leaf must be threaded over the sash tongue, which is correspondingly cumbersome.
• every change in the appearance of the rosette visible on the outside of the door leaf is associated with a change in the entire housing, so that responding to customer requests with regard to the optical appearance of a sash lock is very complex.
• the invention is therefore based on the object of simplifying the assembly of a sash lock with the features mentioned at the outset and also enabling different configurations of the rosette.
• the basic idea of the invention provides that the rosette and the housing of the sash are formed separately and can be connected to one another by means of a positive connection.
• the invention has the advantage that the fastening nut can already be screwed onto the housing during the pre-assembly of the housing with the actuating shaft, because the rosette and housing are now to be attached separately to the door leaf and only connected to one another by the final assembly of the sash lock.
• the housing needs to be attached to the inside of the door leaf and the rosette to be placed on the front of the door leaf, the two parts, depending on the form-fitting designs used, preferably being brought into engagement with one another by rotation.
• the pre-assembled fastening nut By screwing the pre-assembled fastening nut on the outer circumference of the housing until it rests against the door leaf, a firm connection is made between the rosette and the housing of the sash lock.
• the separate design of the housing and the rosette has the advantage that the rosette can be produced as a single component and thus can be easily adapted to customer requirements with regard to its appearance.
• the housing projects with a shoulder outwardly of the door leaf in the direction of the rosette and is enclosed on its circumference by the mounted rosette, which facilitates the provision of the positive connection.
• the positive connection is designed as a bayonet lock.
• radially protruding projections are formed on the attachment of the housing, which protrude into the rosette when the rosette and housing are assembled to one another trained recesses can be inserted and locked against each other with the rosette by relative rotation of the rosette and housing.
• the housing can be secured against rotation in the fastening opening of the door leaf, wherein, according to one embodiment of the invention, the fastening opening formed in the door leaf and accommodating the housing has at least one supporting surface on its edge corresponding to a projection for forming an anti-rotation device for the housing Can have mounting opening.
• a support surface is assigned to each of the projections formed on the housing.
• the support surfaces are preferably arranged in the corner regions of the rectangular fastening opening.
• the rosette is provided with a seal arranged in its contact surface on the door leaf; it can further be provided that a seal is arranged between the inner surface of the rosette surrounding the housing and the outer periphery of the extension of the housing.
• the seal provided in each case is firmly connected to the rosette, whereby according to alternative embodiments of the invention the seal in question can be foamed or is preferably introduced from plastic in the manufacture of the rosette, for example in the so-called 2-component process.
• a viewing window is formed in the rosette and the actuating shaft protrudes beyond the shoulder of the housing leading it into the area of the viewing window of the rosette and is provided with a marking on its protruding area such that the rotational position of the actuating shaft is determined by the identification visible in the window of the rosette can be determined; this creates the possibility of determining the locking or unlocking state of the sash lock by simply inspecting the viewing window.
• the marking consists of a different color, for example red or green, or that the marking consists of a positional statement in writing, for example in the form "open / close” or "on / off ".
• Fig. 2 the subject of Figure 1 after assembly on the door leaf in a front view.
• 3 the object of Figure 2 in section along line III - III in Fig. 2nd
• the cam lock consists of a housing 12 to be fitted on the inside of the door leaf and a rosette 13 to be fitted on the outside.
• the housing 12 projects with a shoulder 19 through the fastening opening 11 of the door leaf 10 and engages in the rosette 13 in such a way that the rosette 13 Approach 19 encloses the housing 12.
• radially projecting projections 20 are formed on the extension 19, to which recesses 21 are assigned in the inner surface of the rosette 13 surrounding the extension 19 such that the projections 20 of the housing in a specific rotational position of the rosette 13 and housing 12 relative to one another the recesses 21 of the rosette 13 are to be inserted and after mutual rotation the projections 20 of the housing 12 move out of the recesses 21 and hook behind correspondingly arranged projections of the rosette 13.
• a fastening nut 15 which is screwed onto an external thread 14 located on the outside of the housing 12, is furthermore arranged, which, when the sash lock is mounted on the door leaf 10, with the mutual positive connection of the rosette 13 and the housing 12 up to a firm contact on the inside of the door leaf 10 is rotated, and in this position the housing 12 and the rosette 13 can no longer separate from one another, so that the sash lock is mounted on the door leaf 10 as a whole.
• the shape of the fastening opening 11 is adapted to the outer circumference of the extension 19, including the four radially projecting projections 20, in that the corner regions of the edge of the fastening opening 11 receiving the projections 20 of the extension 19 are designed as inclined support surfaces 27, which correspond to the outer surfaces of the projections 20 such that the housing 12 with its projections 20 is positively and thus secured against rotation in the mounting opening 1 1.
• the projections 20 have a correspondingly large axial width, so that they extend beyond the abutment on the support surface 27 into the recesses 21 of the rosette 13.
• the rosette 13 and the housing 12 are locked by a relative rotation of the rosette 13 with respect to the housing 12 which is fixed in the fastening opening 11 against rotation.
• An actuating shaft 17 is arranged in the interior of the housing 12, at the end of which a serrated tongue 16 is attached in a rotationally rigid manner and is fastened by means of a screw nut 18.
• the actuating shaft 17 extends with an actuating contour 25 into the shoulder 19 of the housing 12 and forms at its outer end a front collar 26 with which the collar 26 covers the front edge of the housing 12.
• the front collar 26 of the actuating shaft 16 or the actuating contour 25 is covered by a shoulder surface 24 surrounding the insertion opening 22 in the rosette 13. So that the rotational position of the cam lock can be made visible, there are cutouts located opposite one another in this shoulder surface 24 as viewing windows 23, these viewing windows 23 exposing the front face of the collar 26 of the actuating shaft 17.
• the collar 26 is configured on its outer end face in different colors, for example red and green, so that in one rotational position, preferably the locking position of the actuating shaft 17, the areas of the collar 26 colored in red lie in the viewing windows 23, while in the open position of the cam lock when the actuating shaft 17 is rotated accordingly, the green areas of the collar 26 are visible in the viewing windows 23.
