Abstract

The invention concerns a door lock (1) which can be used in right-hand or left-hand mode. It has a hub (4) accommodated in a housing (2) and capable of being rotated from outside by an actuating element, and which displaces a bolt (3) between an open position and a closed position through a displacement element. A blocking element (5) can be used to re-set the lock (1) from right-hand mode to left-hand mode and vice versa. The construction and actuation of the door lock (1) to switch between modes is simplified by mounting the blocking element (5) on the hub (4) so as to be adjustable.

Description

Usable door lock on the left and right

The invention relates to a right and left usable door lock with a spindle mounted in the housing and rotatable externally with a control element, with said spindle the latch being movable between the position open when pushed into the housing and the position closed when it is pushed out of the housing, and with the block piece, which is so adjustable between two positions for shifting between right and left, that in a closed position it is supported by a rigidly connected stop in the direction opposite to the opening direction, and that the vertebra is between The positions of the open and closed positions are rotatable only 90 ° each time, with the direction of rotation being open or open. the positions closed in both uses are opposite each time.

Such a door lock is known from e.g. DE 43 22 877 Cl. For the choice of right / left use, the housing cover is in the area above the quadrilateral vertebra, by which the latch can be rotated to an open and closed position, equipped with backs which interact with the control element which can be inserted from the outside into the vertebra in such a way that both the right and left uses only 90 ° rotation, with the direction of rotation being closed to the open or open position. the opposite is true for both uses. The control element comprises recesses, cooperating with the backrests designed in the housing cover, and must be inserted into the vertebrae receiver and the recess of the housing cover in both applications by 90 ° rotation. Although the control element must be specifically tailored to the door lock, in both applications there may be confusion when operating the door lock.

A further right / left hand door lock is known from DE 92 12 503 Ul. With this door lock, there are two restraint noses that interact with the restraint bodies inside the housing. To shift between the two modes of use, the shutter body is switched inside the housing, which makes the interior of the housing designed relatively demanding.

DE-GM 19 20 339 discloses a further right or left usable door lock, in which a plywood panel is provided with stop tabs that can interact with two diametrically protruding stop surfaces from the vertebra, to limit the rotation. This mechanism is also relatively demanding and difficult to understand for the user from the outset.

It is an object of the invention to create a door lock of the type described above, which is easy to build and use.

This task is solved by the features set forth in claim 1. Thereafter, it is also envisaged that the locking piece for shifting is parallel to the plane of the cover of the housing movably resting on the spindle. In this way, the interior of the lock housing can remain virtually unchanged relative to a lock that is usable for only one use, so that predominantly suitable tools can be used at completion and cost-effective to manufacture. Inside the case, a rigid backrest can be provided in an easy way, and the change in relation to a conventional door lock for one use only essentially refers to a relatively simple change of the spindle.

A simple, unambiguous repositioning capability is achieved by having the locking piece guided by a spindle-based bridge.

It is easy to use in that the locking piece is easily accessible from the outside by means of the housing cavity through a means of exterior housing. e.g. longer or narrower side walls, bottom of housing or housing cover. The tunnel in the side wall has the advantage that the lock can also be moved in its already mounted state.

The mechanism for shifting between the two modes of use is further simple in design and can be operated in a good and unambiguous manner, with the bridge oriented parallel to the plane of the housing cover and in the open or open position. closed parallel to the respective side wall of the housing and in a vertebrae designed with a notch and at the bottom facing away from the housing cover, comprising a notch and providing a locking piece substantially square and on its underside facing the bridge, comprising a groove and a nose which from below it grabs into the undercut. The locking piece can be provided with e.g. as a piece of plastic, simply and indelibly put the clamp on the jumper and fixable.

Both locking positions for both applications can thus be safely adjusted and held so that the bridge between the two locking positions comprises a ramp.

The simple function of the simple design of the gearbox is to ensure that the stop, viewed from the rotational axis of the vertebrae, is arranged outside the locking piece along and parallel to its gearing, the backlash forming a secant about a circle about a radius corresponding to the distance between the rotational axis. the axis and the outermost sections of the locking piece, and that the two positions of the locking piece lie symmetrically with respect to the central rectangle of the section.

There is no need to change the interior of the housing relative to the lock case for only one use if it is intended that the backing is projected vertically from the housing cover into a projecting protrusion and that the projection window forms a tunnel in the housing cover to move the locking piece, leaving it visible and accessible from the outside solely in the closed position. At the same time, access to the locking piece from the outside is easily created when constructing the backrest.

If it is envisaged that both positions of the locking piece are marked on the outside of the housing cover and / or that the position is openly marked with the first, externally visible mark on the vertebra and the corresponding further marking on the outside of the housing cover, the user can easily recognize it, how the locking piece should be positioned for the intended use so that the adjustment can be made easily and without mistake.

Further, the design and safe operation are accelerated by the fact that the gear member is designed as a vertebrae-shaped finger extruder and that the latch comprises a contra-operating control curve with a contra-angular central section and associated end sections connected thereto, and that the transducer is closed in the middle of the central region. section and closed in left-hand position in a top-view view of the housing cover directed toward the end section, which is counterclockwise relative to the center section, and in right-hand use, it is directed clockwise to the end section, and provides a restriction on the rotation of the vertebrae beyond the open position by pushing the suetatel to the abutment area of the end section and by locking the latch to the strut in the housing.

The open and closed positions shall be unambiguous and secure in both applications and shall be recognized by twisting the vertebrae with measures that the vertebrae comprises a parallel section with a housing cover essentially a square outer contour with rounded edges and parallel to the outer contour of the square section on the side. narrow side of housing, supported elastic latch, which extends on its side from the vertebrae side by two laterally elastic fingers, on the longitudinal sides of the housing of water guides, so that they are restrained on the narrow side of the housing such that the convex locking nozzles are attached to the housing cover with their free ends. facing the bottom of the housing.

The invention is explained in greater detail by way of an embodiment and by reference to the accompanying drawings, where FIG. 1A shows a right or left usable lock for left use in the open position; FIG. IB the door lock of FIG. 1A in the closed position, FIG. 2A to 2C the door lock shown in FIG. 1A and IB, in cross-sectional view, side view, side view of the housing cover, respectively. a cross-section showing the setting for right-hand use, FIG. 3 shows the corresponding FIG. 2B, showing the closed position and FIG. 4A to 4C, a door lock in plan view from the bottom of the housing, showing the various settings in conjunction with the corresponding markings, and FIG. 5A to 5C, a further embodiment of the door lock in cross-section in side view and floor plan in open or open position. closed at right-hand setting.

In FIG. 1A shows a door lock 1, which, like the other sketches shown in the door lock, is usable right / left. The left application is shown in the open position, with the latch 3 being pushed into the housing 2. In FIG. 1B shows a corresponding representation in the closed position, the latch 3 being pushed out of the housing through the slot in the side wall 2.1. FIG. a notch inside the housing is shown, with the housing cover 2.3 being removed (cf. Figs. 2A and 2C). To move latch 3 between the closed position and the open position, a vertebra 4 with a coulter 4.1 is provided which grips into the control curve 3.1 with an arched central section and two boundary end sections 3.10 and 3.10 '. The steering curve is designed e.g. by representing the cut or deepening of the latch 3.

In left-hand use, shutter 4.1 is in the open-facing position relative to FIG. lower end section 3.10. To push the latch 3 out into the closed position, the spindle 4 is rotated by means of a non-shown control element with a latch inserted into the corresponding vertebra 4.2 receiver 4. To move the latch 3 into the closed position, the spindle 4 is rotated clockwise so that the latch 3 pushes out from the sidewall slot 2.1. After a rotation of 90 °, the closed position was reached, which contained 4.1, as shown in FIG. IB, reached the center of the arc of the steering curve 2.1. Further rotation clockwise is prevented by the locking piece 5 colliding against a stop 2.5 which is rigidly connected to the housing.

The block piece 5 is pivotably mounted parallel to the side of the square section of the spindle 4 designed bridge 4.3, with the block piece as shown in FIG. IB, for left-hand use, located on the right side of the bridge 4.3. The uncontrolled movement of the locking piece 5 on the bridge 4.3 is reliably prevented by the nodal ramp 4.4 on the side face of the bridge 4.3. However, the locking piece 5 can be easily pushed in the closed position along and parallel to the stop 2.5 by a simple means, e.g. ballpoint tips across the ramp 4.4 into the left position so that the agent is inserted into the conical recess 5.1.

The locking piece 5 is seated in the closed position shown in FIG. IB, to the stop 2.5, wherein this stop position is obtained by forming a secant of the circle with the center of the axis of rotation of the vertebra 4 by the backrest plane 2.5, wherein the radius r corresponds to the distance between the rotary axis and then the furthest point P locking piece 5. Due to this stop position, the spindle 4 is rotatable only counter-clockwise until the open latch position is reached and the feeder 4.1 is directed towards the final section 3.10. In the open position, no further rotation of the vertebrae is possible in a counter-clockwise fashion, since the socket 4.1 rests against the stop area of the end section 3.10 and the latch 3 collides against the strut inside the housing.

To reposition the door lock for right use, the locking piece 5 in the closed position on the bridge 4.3 must be pushed across the center vertical of the chopping block to the other position on the other side of the ramp 4.4. Such positioning of block block 5 for right use is shown in FIG. 2B, 3 and 4A. If the latch 3 in the side wall 2.1 is still on the left side, the buckle 4.1 is in the open position directed to the upper end section 3.10 ', as shown in FIG. 2B. To move the latch 3 to the closed position, the spindle 4, in plan view from the cover 2.3 of the housing, rotates counterclockwise, with the finger curved as shown in FIG. 3, in the closed position, rests in the center of the arc section of the steering curve 3.1, as is the case in FIG. IB in left use. In the closed position, however, the locking piece is now as shown in FIG. 3, positioned on the left edge of the bridge 4.3, so that the locking of the locking piece 5 on the stop 2.5 prevents further rotation of the spindle 4 counterclockwise across the closed position. In contrast, rotation of the vertebra 4 clockwise across the position is open without further possibility. Further rotation of the spindle 4 clockwise over the open position is prevented by the squeeze 4.1 colliding against the abutment area of the end section 3.10 'of the control curve 3.1 and also the latch 3 resting on the housing bracket 2.

As can be seen from FIG. 2C is a bridge 4.3 formed by a cutout 4.6 in the square section of the spindle 4, with the lateral area of the bridge on its from the cover 2.3 of the housing away from the quadrilateral receiver 4.2 away from the underside of the spanner 4.5. Along the outer contour, the roughly quadric locking piece 5 comprises a groove of cross-section 4.3 of the bridge 4.3 adapted to be grooved and, especially if made of plastic material, can be fastened to the bridge 4.3 by means of a clip. It is designed to a quadrilateral receiver 4.2, the groove arm so designed that, when moving the block piece 5, it can be retracted with the aid of the means to overcome the ramp 4.4. In FIG. 2C also shows the tapered recess 5.1 of block 5.

The stop 2.5 for locking piece 5 is clearly visible in FIG. 2A. It is designed as a pier from cover 2.3 of the housing, with a breakthrough in the form of a rectangular window through which the locking piece 5 from the outside in the closed position is freely accessible to be moved to the R and L positions, corresponding to both uses, as presented in FIG. 4A. In the open position, the locking piece 5 is not visible from the outside as shown in FIG. 4B and 4C. In the open position, the selected mode of use is instead indicated by a notch 4.7 on one side of the quadrilateral receiver 4.2 of the vertebra 4, the vertebra 4 projecting into a corresponding circular cutout of the housing cover 2.3, with a cross-sectional portion, thereby safe held in place. The corresponding R and L marks for both applications are embedded on the outside of the housing cover 2.3, so that the adjustment is visible from the outside without further ado. The selected mode of use may also become visible in the open position by the fact that the notch of the cover 2.3 of the housing is positioned at a position in which the locking piece 5 is open in the position.

As further illustrated in FIG. 2A comprises the bottom 2.2 of the housing 2 of different recesses, which, inter alia, are guidedly held by the latch 3 and the spindle 4. In FIG. 2A shows the upper side of the square section of the vertebra 4 resting on the flat side 6, as also seen in FIG. 2B. The latch 6 comprises two lateral toe-shaped spring sections extending parallel to and guided by the longitudinal sides of the housing 2. These elastic snap-on lugs 6 are convexly curved to the cover 2.3 of the housing and project with their free protrusions to the upper narrow side wall of the housing 2, where they are elastically supported. In rotation of the spindle 4 by means of a non-shown control element, the snap deflects upward against its spring force, the square section with its rounded edges sliding along the contact side of the snap until the second end position of the latch is reached and the side of the square section of the spindle 4 is offset by 90 °. it does not sit on the locking side of the snap 6. In this way, the position is closed and the position open is given unambiguously, clearly communicating to the user the position closed or. open.

As further illustrated in FIG. 2A and 2B comprise a housing 2 for mounting on a door on its narrow side wall shaped extensions 2.4. Further, inside the housing, bordering on a narrow side wall, there are provided eccentrics 7 for the pivot bars.

It should also be noted that receiver 4.2 does not have to be designed as a quad, but may have an appropriate outline corresponding to the control element used.

In FIG. 5A to 5C, a further embodiment of the door lock 1 is shown in which the stop 3.2 for the locking piece 5 is mounted, e.g. shaped, on latch 3, on its side facing the housing cover. The stop 3.2 comprises a preferred vertical support 3.3, by which the latch 3 relies on the cover 2.3 of the housing, e.g. at a puncture of 2.30, as well as a horizontal support 3.4, by which the latch 3 is supported on the inside of the cover 2.3 of the housing. Supports 3.3 and 3.4 not only provide additional stop stability, but also improved latch control 3.

In FIG. 5B and 5C are also shown in the sidewalls 2.1 arranged punctures 2.10 through which, e.g. Using a latch, move the door lock 1 from right to left or vice versa. This is especially advantageous when the door lock is mounted on the door and the block piece 5 is not accessible through the window in the form of a puncture 2.30 in the cover 2.3 of the housing. Breakthroughs

2.10 in the sidewalls 2.1, of course, may also be provided for in the first embodiment, in which a stop 2.5 is mounted on the cover 2.3 of the housing.
