DETAILED DESCRIPTION

[0031] FIG. 2 shows a first embodiment of an accessory 30 according to the invention for transferring a laser line 31 to a work surface 32. The accessory 30 is combined with a laser receiver 33 and is held by the operator against the work surface 32 that is in the form of a wall. The task for the operator consists in transferring the laser line 31 as accurately as possible to the work surface 32.

[0032] The accessory 30 comprises a base plate 35, a connection device 36 connecting the accessory 30 to the laser receiver 33, and a rotary joint 37. The base plate 35 has a front side 38 and a rear side located opposite the front side 38. The rear side of the base plate is designed to be flat and is used to position the accessory 30 with the laser receiver 33 on the work surface 32. The size of the base plate 35 is adapted to the size of the laser receiver 33 and is selected to be such that the accessory 30 can be stably positioned on the work surface 32. The rotary joint 37 connects the connection device 36 to the base plate 35, wherein the connection device 36 is rotatable about an axis of rotation 39 relative to the base plate 35.

[0033] The laser receiver 33 comprises a housing 41, a display 42, an operating device 43 with a plurality of operating elements, and an elongated sensor element 44, the longitudinal direction of which defines the measurement direction 45 of the laser receiver 33. The display 42, the operating device 43, and the sensor element 44 are arranged in a front face 46 of the housing 41. The laser receiver 33 has in one side face two magnetic elements or two steel elements with the aid of which the laser receiver 33 can be attached via a magnetic connection.

[0034] In order to support the operator in transferring the laser line 31 to the work surface 32, the accessory 30 has a first marking element 47 and a second marking element 48, which are attached to the base plate 35. The first and second marking elements 47, 48 are designed as foldable rulers and are adjustable about a pivot axis between a folded-in state and a folded-out state. The first marking element 47 is arranged on a first side face 51 of the base plate 35 and is adjustable about a first pivot axis 52, and the second marking element 48 is arranged on a second side face 53 of the base plate 35 and adjustable about a second pivot axis 54.

[0035] The first and second pivot axes 52, 54 are arranged parallel to the first and second side faces 51, 53 and perpendicular to the axis of rotation 39 of the rotary joint 37. This arrangement has the advantage that the first and second marking elements 47, 48 can be designed to be longer than marking elements having pivot axes that are arranged parallel to the axis of rotation 39 of the rotary joint 37. As noted above, in a third preferred embodiment, the accessory has a spray device shown schematically in FIG. 2 as 101, which comprises a container 102, a control element 103, and an actuating element 104. The spray device preferably has a user interface 105 and/or an interface to the laser receiver.

[0036] FIG. 3 illustrates the accessory 30 according to the invention of FIG. 2 without the laser receiver 33 and marking element 38 removed for clarity. The accessory 30 comprises the base plate 35, the connection device 36, and the rotary joint 37.

[0037] The connection device 36 is used to connect the accessory 30 to the laser receiver 33. In the exemplary embodiment, the connection device 36 is designed in the form of an angle plate, which has a horizontal plate 55 and a vertical plate 56 oriented perpendicularly to the horizontal plate.

[0038] A first magnetic element 57 and a second magnetic element 58 are arranged in the vertical plate and form a magnetic connection with the magnetic elements of the laser receiver 33 (FIG. 2). As an alternative to the arrangement in the vertical plate, the first and second magnetic elements can be arranged in the horizontal plate and form a magnetic connection with magnetic or steel elements of the laser receiver 33.

[0039] By means of the rotary joint 37, the angle plate 36 is adjustable about the axis of rotation 39 within an angular range between a first angle θ.sub.1 and a second angle θ.sub.2. (See, e.g., FIG. 4B). In the exemplary embodiment, the angle plate 36 is adjustable within an angular range of approx. 90° between the first angle θ.sub.1 of 0° and the second angle θ.sub.2 of approximately 90°.

[0040] FIGS. 4A, B show the accessory 30 of FIG. 2 in a first rotational position (FIG. 4A) and in a second rotational position (FIG. 4B). The base plate 35 is arranged on the work surface 32 with a rear side 59 located opposite the front side 38.

[0041] The visibility of the laser line 31 (see, e.g. FIG. 2) depends, among other things, on the angle at which the laser beam generated by a rotating laser or line laser is incident on the sensor element 44 of the laser receiver 33, wherein perpendicular incidence is preferred. The first rotational position (FIG. 4A) corresponds to the first angle θ.sub.1 of 0°, and the second rotational position (FIG. 4B) shows an intermediate angle of approx. 45° in the angular range of the rotary joint 37 between the first and second angle.

[0042] FIGS. 5A-C show a second embodiment of an accessory 60 according to the invention for transferring a laser line 61 onto a work surface 62. The accessory 60 is combined with the laser receiver 33 and is held by the operator against the work surface 62 that is in the form of a ground or floor. In this case, FIG. 5A shows the accessory 60 and the laser receiver 33 in a three-dimensional illustration, FIG. 5B shows them in a view of the front side of the laser receiver 33, and FIG. 5C shows them in a view of a side face of the laser receiver 33.

[0043] The accessory 60 comprises a base plate 63, a connection device 64 connecting the accessory 60 to the laser receiver 33, and a rotary joint 65. The base plate 63 has a front side 66 and a rear side 67 located opposite the front side 66.

[0044] The rotary joint 65 connects the connection device 64 to the base plate 63, wherein the connection device 64 is rotatable about an axis of rotation 68 relative to the base plate 63. With the aid of the rotary joint 65, the connection device 64 is adjustable about the axis of rotation 68 within an angular range between a first angle θ.sub.1 and a second angle θ.sub.2. In the exemplary embodiment, the connection device 64 is adjustable within an angular range of approx. 90° between the first angle θ.sub.1 of approx. −45° and the second angle θ.sub.2 of approximately 45°.

[0045] In order to support the operator in transferring the laser line 61 to the work surface 62, the accessory 60 has a first marking element 71 and a second marking element 72, which are attached to the base plate 63. The first and second marking elements 71, 72 are designed as fixed indication notches attached to the side faces of the base plate 63. The first marking element 71 is attached to a first side face 73 of the base plate 63, and the second marking element 72 is attached to a second side face 74 of the base plate 63.

[0046] FIGS. 6A-C show the accessory 60 of FIG. 5 in three different rotational positions. The accessory 60 is adjustable about the axis of rotation 68 between the first angle θ.sub.1 and the second angle θ.sub.2. FIG. 6A shows the accessory 60 in a first rotational position, FIG. 6B shows it in a second rotational position, and FIG. 6C shows it in a third rotational position.

[0047] The visibility of the laser line 61 depends, among other things, on the angle at which the laser beam generated by a rotating laser or line laser is incident on the sensor element 44 of the laser receiver 33, wherein perpendicular incidence is preferred. The first rotational position of the accessory 60 (FIG. 6A) corresponds to the first angle θ.sub.1 of −45°, the second rotational position of the accessory 60 (FIG. 6B) shows an intermediate angle of approx. 0° in the angular range of the rotary joint 65 between the first and second angle, and the third rotational position of the accessory 60 (FIG. 6C) corresponds to the second angle θ.sub.2 of +45°.
