Definitions

• the object of the invention is to provide a device for continuously marking the same distances when carrying out roof battens, cladding or slab laying in the construction industry, which makes the time-consuming measuring of equal distances with the yardstick on a construction site unnecessary.
• this device should, if possible, be designed in such a way that the distance can be set within a predetermined range, in which a continuous marking then takes place when the device is operated.
• the device according to the invention consists of a drum-like body, the cylindrical outer surface of which has marking means at a predetermined mutual distance and on the axis of which a holding device is articulated to enable its unwinding onto the component to be marked.
• the drum-like body is simply rolled off on the surface to be marked.
• the marking means protruding from the drum circumference then mark the desired ones Distances.
• the roofer simply has to drive the device along on the rafters and thus the slat distances are marked evenly and precisely.
• the advantage over measuring with a folding rule is not only in the shorter working hours, but also in the fact that an incorrect measurement is practically no longer possible.
• the distances are marked much more accurately than if you were to measure with a ruler on such a construction site.
• the drum-like body consists of individual segments which can be adjusted in the radial direction, with adjacent segments overlapping one another at least in the area of their lateral surfaces in such a way that even with maximum radial adjustment of the individual segments, a closed ne or almost closed outer surface is retained.
• the distance dimension to be marked can be set within a predetermined range.
• the individual segments can, for example, be guided in radial slots of a circular disc or an axis cross - in the latter case if four segments are present - and in the area of these slots, e.g. B. can be locked by screw connections.
• the segments themselves which are made of plastic, for example by injection molding, can have lateral cavities.
• the marking means for example in the form of a micro-fabric rubber, can be accommodated in such a cavity, which opens into the jacket surface in a slot-like manner, the edge of this fabric rubber emerging from the slot.
• a further embodiment of the invention enables a simultaneous radial adjustment of all segments in that on the side of the circular disc opposite the segments there is axially arranged a further disc which is rotatable relative to the segments and which has a number of curved slots corresponding to the number of segments for receiving the segment attachment. By turning this additional disc, all segments are then simultaneously adjusted in the radial direction, which makes handling the device easier.
• a simultaneous radial adjustment of all segments enables an embodiment of the device in which on the axis of the drum-like body consisting of segments, an actuating body which engages with the segments and is profiled in such a way that the segments are rotated radially outward against its spring tension by its rotation are movable.
• the actuating body can consist of an eccentric with a number of eccentric surfaces running symmetrically to the drum axis corresponding to the number of segments.
• 1 shows a side view of an embodiment of the device according to the invention
• 2 shows a cross section through the holding device of this device
• FIG. 3 is a plan view of this device according to FIG. 1,
• FIG. 6 shows the end view of a segment according to FIG. 5,
• the device is clamped in a holding device 1, which consists of the actual handle and a fork-shaped part 5.
• This fork-shaped part 5 has two pins 6, between which the circular disk 8 shown in FIGS. 8 and 9 is clamped. These pins 6 engage in the two
• the circular disk 8 in this case has four radial slots, each at 90 °, which serve to guide the segments shown in FIGS. 4 to 6. 1 and 3, only two segments 2 are shown, namely in the two end positions defined by the slots 4.
• a rib 17 is provided on the segment 2, the width of which corresponds to the slot width 4.
• a scale is arranged radially on its side facing the circular disk 8, on which the respectively desired distance can be read. After appropriate setting of the segments, they are fastened using the screw 12 and the wing nut 3. From FIGS. 5 and
• the segments 2 have lugs 11 and 14 on their lateral boundaries, which are attached on opposite sides. During the radial adjustment of the segments, these lugs ensure that a closed or almost closed drum running surface is retained, so that the rolling process is not disrupted.
• these parts produced by injection molding are provided with cavities 15, as can be seen in FIG. 4.
• One of these cavities serves for sewing on a micro-fabric rubber 13, which is introduced in such a way that one of its edges passes through the
• the cylindrical surface of the drum-like body consists of mutually toothed segments 24, which by means of one on a
• Drum axis 20 mounted actuator 26 can be moved radially outward against a spring tension.
• the actuating body consists of a gearwheel 26.
• the segments 24 are guided by means of pins 22 anchored in two outer disks, which engage in guide grooves 27 of the segments 24.
• the spring tension mentioned for the segments 24 is brought about by a rubber ring 28 which is placed in a groove around the circumference of the segments 24.
• Segments 24 are pressed outwards, as a result of which the outside diameter of the drum-like body is enlarged. As a result of this enlargement, the spacing of the signature stamp 21 attached to the circumference of the segments 24 also changes.
• the change in the distance between the marking stamps and thus the change in the marking distance can also take place by means of rings of various thicknesses mounted on the drum-shaped body. The marking stamps are then attached to the outermost ring.
