Definitions

• the invention relates to a door lock, which can be used on the right or left, with a nut accommodated in a housing and rotatable from the outside with an actuating element, with which, via an adjusting element, a bolt between an open position inserted into the housing and one from the The extended position of the housing can be moved, and with a blocking piece which can be adjusted between two positions for switching between the right / left use in such a way that in the closed position it is supported on a stop fixed to the house in a direction opposite to the opening direction , and that the nut can only be rotated back and forth by 90 ° between the open and the closed position, the direction of rotation being opposite in each case for the two types of use to achieve the open position or the closed position.
• a door lock of this type is specified for example in DE 43 22 877 C1.
• the housing cover in the area above a square nut, with which a bolt can be moved by turning it into an open and a closed position is provided with stops which can be inserted into the nut from the outside
• the actuating element cooperate in such a way that only a 90 ° rotation is possible both in the right-use mode and in the left-use mode, the direction of rotation from the closed position to the open position and vice versa being reversed in the two types of use.
• the actuating element has cooperating formations with the stops formed in the housing cover and, in the two types of use, must be rotated through 90 ° in a receptacle of the nut and the recess in the housing cover. In addition to the fact that the actuating element must be specially matched to the door lock, there can also be confusion in the handling of the door lock in the two types of use.
• Another door lock with right / left use is specified in DE 92 12 503 U1.
• two stop lugs are provided on a nut, which interact with a stop body in the interior of the housing.
• the stopper body is adjusted inside the housing, for which purpose the interior of the housing is designed to be relatively complex.
• DE-GM 19 20 339 discloses a further door lock that can be used on the right or left, in which a locking plate is provided with stop tabs which can interact with two stop surfaces projecting diametrically from the nut in order to limit rotation. This mechanism is too relatively complex and not easy for a user to understand from the start.
• the object of the invention is to provide a door lock of the type described at the outset, which is simple in structure and in operation.
• the blocking piece is adjustably mounted on the nut.
• the interior of the lock housing can remain practically unchanged compared to a lock that can be used in only one type of use, so that largely corresponding tools can be used in manufacture and manufacture is inexpensive.
• a fixed stop in the interior of the housing can be provided in a simple manner, and essentially the modification compared to a normal door lock for only one type of use relates to the relatively simple modification of the nut.
• a simple, unambiguous adjustment possibility is achieved in that the blocking piece is displaceably guided on a web formed on the nut.
• the handling is simple in that the blocking piece for adjustment via an opening in the housing wall, i.e. e.g. the long or narrow side wall, the housing base or the housing cover is accessible from the outside by means of a handle.
• a breakthrough in the side wall has the advantage that the lock can be changed even in the assembled state.
• the mechanism for switching between the two types of use continues to have a simple structure and is easy and clearly usable because that the web is directed parallel to the plane of a housing cover and in the open or closed position parallel to a respective side wall of the housing and is formed by a recess in the nut and has an undercut on an underside facing away from the housing cover and that Blocking piece is essentially cuboid and has on its underside facing the web a fitting groove and a nose under the undercut nose.
• the blocking piece can, for example as a plastic piece, be simply and securely attached to the web in a clip-like manner and can be moved.
• the two positions of the blocking piece for the two types of use can be set and maintained safely in that the web has a ramp between the two positions of the blocking piece.
• a simple function with a simple design of the changeover mechanism is ensured in that the stop, seen from the axis of rotation of the nut, is arranged outside the blocking piece along and parallel to its adjustment path, the stop being a second to a circle around the rotation axis forms, the radius of which corresponds to the distance between the axis of rotation and the most distant portion of the blocking piece, and that the two positions of the blocking piece are symmetrical to the central perpendicular of the secant.
• the interior of the housing need not be modified at all compared to a lock housing for only one type of use if it is provided that the stop is formed by a notch projecting vertically from the housing cover into the interior of the housing and that the notch is formed by the notch Window in the housing cover forms the opening for the adjustment of the blocking piece, which is only visible and accessible from the outside in the closed position. At the same time, the accessibility of the blocking piece is created from the outside in a simple manner when the stop is formed.
• the two positions of the blocking piece are marked on the outside of the housing cover and / or that the open position is marked by a first marking on the nut which is visible from the outside and a corresponding further marking on the outside of the housing cover, the user can recognize without difficulty how he has to position the blocking piece for the desired type of use, so that the setting can be made easily without confusion.
• the training and safe function is favored by the fact that the adjusting member is formed as a finger-like driver molded onto the nut and that the bolt has a control cam cooperating with the driver with an arcuate central section and end sections adjoining it laterally, and that the driver in the closed position in the middle of the middle section and in the open position in the left-hand use in plan view from the housing cover in the end section lying counterclockwise with respect to the middle section and in the right-hand use in the clockwise end section and that the limitation of the turning of the nut beyond the open position is given by the driver striking the stop portion of the end section and by the bolt resting on an abutment in the housing.
• the measures are taken to recognize that the nut has a section parallel to the housing cover with an essentially square outer contour with rounded edges and that along the outer contour the square section is supported on a side parallel to the narrow side of the housing, a resilient tumbler which is supported on its side facing away from the nut by means of two lateral resilient finger-like extensions on the long sides of the housing on the narrow side of the housing such that the extensions are directed under the convex curvature of the housing cover with their free ends towards the housing base.

• a type of left-hand use is shown in the open position, with a latch 3 being inserted into a housing 2.
• 1B shows a corresponding illustration in a closed position, the bolt 3 being pushed out of the housing 2 through a slot in a side wall 2.1.
• the figures show a section of the interior of the housing, with a housing cover 2.3 (cf. FIGS. 2A and 2C) being removed.
• a nut 4 is provided with a driver 4.1, which engages in a control curve 3.1 with an arcuate central section and two adjoining end sections 3.10 and 3.10 '.
• the control curve is formed, for example, by a shoulder in a recess or a recess in the bolt 3.
• the driver 4.1 is deflected in the open position into the lower section 3.10 according to the figures.
• the nut 4 is rotated by means of an actuating element, not shown, with a square which is inserted into a corresponding receptacle 4.2 of the nut 4.
• the nut 4 is turned clockwise, so that the bolt 3 is pushed out of the slot in the side wall 2.1.
• the closed position is reached, in which, as shown in FIG. 1B, the driver 4.1 has reached the center of the arcuate section of the control cam 2.1.
• a further clockwise rotation is prevented by a blocking piece 5 striking a stop 2.5 fixed to the housing.

• An inadvertent displacement of the blocking piece 5 on the web 4 is reliably avoided by a knob-like ramp 4.4 on a side surface of the web 4.3.
• the blocking piece 5 can, however, in the closed position along and parallel to the stop 2.5 by means of a simple handle, such as e.g. a ballpoint pen tip, can be moved slightly over the ramp 4.4 to the left position by inserting the handle into a conical recess 5.1.
• the blocking piece 5 sits in the closed position shown in FIG. 1B on the stop 2.5, this stop position being achieved in that a secant of a circle is formed with the stop plane of the stop 2.5 with the center point M of the axis of rotation of the nut 4, the radius r corresponds to the distance between the axis of rotation and the most distant point P of the blocking piece 5. Because of this stop position, the nut 4 is only rotatable counterclockwise until the open position of the bolt is reached and the driver 4.1 is deflected into the end section 3.10. In the open position, a further turning of the nut counterclockwise is not possible, since the driver 4.1 comes to rest on a stop area of the end section 3.10 and the bolt 3 abuts an abutment inside the housing.
• FIGS. 2B, 3 and 4A Such positioning of the blocking piece 5 for the right-hand use is shown in FIGS. 2B, 3 and 4A.
