Definitions
- the present invention relates to an accessory for a laser receiver for transmitting a laser line according to the preamble of claim 1.
- laser receivers In order to detect the center of a laser beam generated by a rotating rotating laser or a line laser, laser receivers are used which have a housing with a line-like sensor element running along a longitudinal side for detecting the laser beam.
- the sensor element should be directed towards the laser beam in such a way that the laser beam intersects the sensor element vertically and centrally.
- a display of the laser receiver shows when the center of the sensor element has been hit. This area is assigned a marking or notch in one long side of the housing, with which the laser line can be transferred to the work surface.
- FIGN. 1A, B show a known laser receiver 10 with an accessory for carrying a laser line 11 onto a work surface 12.
- FIG. 1A shows the laser receiver 10 in a view of a front side 13 of the laser receiver 10 and FIG. 1B in a view of a rear side 14 of the laser receiver 10.
- the laser receiver 10 comprises a housing 15, a first display 16, a second display 17, an operating device 18 with several operating elements and a sensor element 19.
- the first display 16, the operating device 18 and the sensor element 19 are arranged in a front surface 21 of the housing 15.
- a steel plate and a fold-out support element 23 are arranged on a rear surface 22 of the housing 15.
- the steel plate is integrated into the housing 15; the laser receiver 10 can be attached directly to a magnetic holder or magnetic objects using the steel plate.
- a first marking element 25 is integrated into a first side surface 24 of the housing 15, and a fold-out second marking element 27 is arranged in a second side surface 26 of the housing 15.
- the support element 23 is adjustable between a folded position and an unfolded position.
- a recess 28 for the support element 23 is flush with the housing 15 in the folded position so that the laser receiver 10 can be positioned with the rear surface 22 on a flat work surface.
- the support element 23 can be folded out by about 90 ° and made light positioning of the laser receiver 10 on the floor or on a horizontal work surface.
- the known laser receiver 10 has the disadvantage that the support element 23 only rests on the work surface 12 with a narrow contact surface and the position of the laser receiver 10 is unstable when the laser line 11 is transferred to the work surface 12. In addition, the angular position of the known laser receiver 10 cannot be changed, so that the sensor element 19 cannot be optimally aligned with the incident laser beam.
- the object of the present invention is to develop an accessory for a laser receiver which facilitates the transmission of a laser line from a laser receiver to the work surface for the operator.
- the laser line should be transferred to the work surface with a high degree of accuracy.
- the accessory according to the invention for a laser receiver for transmitting a laser line to a work surface includes:
- connection device for connecting the laser receiver with the accessory part
- a swivel joint which is arranged between the base plate and the connecting device, wherein the connecting device is rotatable about an axis of rotation relative to the base plate between a first angle and a second angle.
- the accessory according to the invention enables stable positioning of the laser receiver on the work surface and precise alignment of the laser receiver on the laser beam to be grasped.
- the back of the base plate is placed on the work surface, to which the laser line is to be transferred.
- the size of the base plate is adapted to the size of the laser receiver that is to be connected to the accessory and is chosen so large that the accessory can be stably positioned on the work surface.
- the swivel joint which is arranged between the base plate and the connecting device, enables the laser receiver to be precisely aligned with the laser beam, so that the sensor element is arranged as perpendicularly as possible to the laser beam.
- the first and second angles limit an angular range in which the swivel joint can be adjusted.
- the swivel joint can preferably be locked in at least one rotational position between the first angle and the second angle.
- lockable means that the swivel joint is securely arranged in the rotary position and the rotary position is not left without intervention by the operator.
- a swivel joint which can be locked in at least one rotational position between the first and second angle, enables the laser receiver to be stably arranged in a rotational position so that the laser line that the laser beam generates on the sensor element can be transmitted to the work surface.
- the swivel joint can be locked in several rotational positions between the first angle and the second angle.
- a swivel joint which can be locked in several rotational positions between the first and second angle, makes it possible to arrange the laser receiver in relation to the laser beam in such a way that the laser beam strikes the sensor element as perpendicularly as possible.
- the visibility of the laser line depends, among other things, on the angle at which the laser beam strikes the sensor element, with vertical impingement being given before.
- the swivel joint can particularly preferably be locked in any rotational position between the first angle and the second angle.
- the visibility of the laser line depends, among other things, on the angle at which the laser beam strikes the sensor element, vertical impingement being preferred.
- a swivel joint which can be locked in any rotational position between the first and second angle, enables the laser receiver to be arranged in relation to the laser beam in such a way that the laser beam strikes the sensor element perpendicularly.
- the accessory part has a marking element which is arranged on a side face of the base plate.
- a marking element which is arranged on a side surface of the base plate has the advantage that the marking element rests on the work surface and the laser line can be transferred to the work surface with high accuracy.
- the marking element is preferably adjustable as a foldable ruler about a pivot axis between a folded position and an unfolded position.
- An as A folding ruler designed marking element has the advantage that the marking element can be made longer than a fixed marking element which is arranged on a side surface of the base plate.
- the pivot axis is arranged perpendicular to the axis of rotation of the swivel joint. If the pivot axis of the marking element is arranged perpendicular to the axis of rotation of the swivel joint, the marking element can plunge into the side surface of the base plate in the folded position and be flush with the side surface. In addition, with this arrangement of the pivot axis, the size of the base plate can be used. The longer the marking element, the better the operator can transfer the laser line onto the work surface.
- the accessory part has a first marking element which is arranged on a first side surface of the base plate, and a second marking element which is arranged on a second side surface of the base plate. If the base plate has a first and a second marking element, which are arranged on the first and second side surface of the base plate, the laser line can be transmitted with high accuracy on both sides of the work surface.
- the first marking element can be adjusted as a foldable first ruler around a first pivot axis between a folded position and an unfolded position and the second marker element can be adjusted as a foldable second ruler around a second pivot axis between a folded position and an unfolded position.
- a foldable first and second ruler have the advantage that the first and second marking elements can be made longer than fixed marking elements which are arranged on the side surfaces of the base plate.
- the first pivot axis is arranged perpendicular to the axis of rotation of the Drehgelen kes and the second pivot axis is arranged perpendicular to the axis of rotation of the rotary joint.
- the first and second marking element can plunge into the first and second side surface of the base plate in the folded position and are flush with the side surfaces.

- An accessory with a spray device enables the laser line to be easily transferred to the work surface.
- the Spray device transfer the laser line to the work surface.
- the spray device has, for example, a nozzle that is aligned parallel to the laser line.
- the spray device preferably has a user interface and / or an interface to the laser receiver.
- a spray device which has a user interface and / or an interface to the laser receiver, offers the possibility of transferring a laser line to the work surface by triggering the operator or by triggering the laser receiver.
