Definitions

the invention relates to a firewood circular saw according to the preamble of claim 1.
the saw blade associated, mounted on the frame protective housing is integrally formed. Accordingly, the working gap is determined in size. Logs or trunk sections whose diameters are larger than the clear opening of the working slit can not be sawn off. As a rule, however, firewood is not sorted by diameter, so that logs or rollers with a comparatively large diameter can be contained in a batch. These have to be split into shorter pieces before subdivision. The known arrangements therefore prove to be not user friendly enough.
the pivoting of the upper part of the protective housing advantageously allows an extension of the clear input width of the working gap. It is therefore also possible to machine billets or rollers with a comparatively large diameter. Nevertheless, the return device and the stop arrangement result in a high level of occupational safety.
the designed as an open-top box lower part in the area facing away from the entrance of the working gap edges of its opening with upwardly projecting, the upper part associated, lateral guide straps be provided. These ensure a reliable lateral guidance of the upper part, whereby the work safety is increased.
the guide tabs for receiving the upper part associated pivot axis and elements of the stop assembly and the return device are.
At least one guide tab can have concentric arc slots to a bearing pin associated with the upper part, in each of which a stop pin attached to the adjacent side wall of the upper part, preferably a continuous stop pin, engages.
This design of the stop device makes it difficult in an advantageous manner unwanted interference with the stop device, whereby the security is increased.
the stop pin can also attack the upper end of a return spring in an advantageous manner, the lower end can engage a pin bridging the guide tabs, so that there is a compact design of the return device.
a further advantageous measure may consist in that the bearing remote end of the upper part is formed as a run-up slope. This ensures that the upper part is automatically swung up by a starting workpiece.
the lower edge of the upper part with respect to the axis of the saw blade can be concave, which has a favorable effect on the pivoting process.
FIG. 1 and 2 constructed according to the Wippsägenkar firewood circular saw includes a mobile machine frame 1, which is expediently constructed in the manner of a truncated pyramid.
a shaft 2 is mounted, which cooperates on the one hand with a drive motor, not shown, and on the other hand carries a machine frame on one side flanking saw blade 3.
a receiving channel for sawing exhibiting feed member is provided at the front of the machine frame 1 a relative to the stationary saw blade 3 movable.
This is formed in the example shown as an axis parallel to the saw blade axis pivotable rocker 4, which has a receiving channel 5 for the pole containing, in cross-section v-shaped receiving piece 6.
the saw blade 3 is associated with a mounted on the adjacent side edge of the machine frame 1 protective housing. This consists of a lower portion of the saw blade 3 receiving lower part 7 and a cross over this, an upper portion of the saw blade 3 associated Upper part 8.
the upper edge of the lower part 7 is rising from front to rear.
the lower edge of the upper part 8 is sloping from front to back.
a working gap 9 opening towards the advancing member is limited.
the clear input width of the working gap 9 limits the permissible thickness of the workable shegguts.
the upper part 8 is pivotable about an axis parallel to the saw blade axis 10 from a lower, the figure 1 underlying stop position in an upper, the figure 2 underlying stop position.
the upward pivoting movement is expediently counter to the force of a restoring device, which automatically returns the upper part 8 to the lower stop position.
woods with a normal diameter of the type indicated at 11a in FIG. 1 can be cut.
Firewood batches may, however, also include woods with a much larger diameter of the kind indicated in FIG. 1 at 11 b.
the pivot axis 10 of the upper part 8 is located in the rear, that is in the area of the protective housing remote from the entrance of the working gap 9.
the lateral guide plates 12 provided in the rear of the protective housing with its upper edge überrag-, which are expediently formed as flat sheets, which bear against the opposite inner sides of the lower part 7 forming box and are connected to the box side walls. The rear edge of said tabs may rest against the rear wall of the box.
the upper part 8 is expediently designed as a downwardly open, in cross-section U-shaped box, in which the guide plates 12 engage. These lie on the box inside, so that there is a reliable, lateral guidance.
a lateral guide tabs 12 bridging, indicated in Figure 4 bolt 10a is provided, which projects beyond the lateral guide tabs 12 and engages in associated, visible in Figure 4 above holes 10b of the upper part 8 forming box.
At least one, preferably both of the bolts 10a carrying guide plates 12 are, as shown in Figure 4 further below, provided with a pin axis to the axis and thus to the pivot axis of the upper part 8 concentric arcuate slot 13.
the upper part 8 contains the curved slot 13 of a guide plate 12 in the example shown, the aligned arcuate slots 13 both guide plates 12 associated, laterally projecting, indicated in Figure 4 above pin 14, which engage in the respective adjacent arch slot 13.
the upper part 8 may be provided with a side projecting pin bridging its lateral walls.
Each of the engaging in an arcuate slot 13 pin 14 acts as a stop member, which starts to limit the pivot angle of the upper part 8 at the ends of the associated arcuate slot 13. In the lower position, the stops are at the lower end, in the upper position at the upper end of the associated curved slot 13.
a spring 15 shown in FIG. 3 is provided in the example illustrated. This is formed in the example shown as a tension spring, the upper end of the upper part 8 and the lower end of the lower part 7 attack.
the upper end of the spring 15 may suitably engage the abovementioned pin 14a provided for forming the pins 14.
the lower end of the spring 15 can engage a pin 16 bridging the guide tabs 12 or side walls of the lower part 7.
the restoring device can also be formed by a spring arrangement containing a plurality of springs. The use of other types of springs, such as a bow spring, etc. would be conceivable.
the bearing remote end of the upper part 8 is useful as formed with the lower edge of the upper part 8 an obtuse angle forming run-on slope 17.
Thicker blanks of the type indicated at 11 b in Figure 1 run, as shown in Figure 1 can be seen on the run-on slope 17, whereby the upper part 8 is raised.
the adjoining the run-on slope 17 lower edge 18 of the upper part 8 is formed concave with respect to the axis of the saw blade 3. This facilitates the sliding of the upper part 8 on a piece of wood which presses it up, as can be clearly seen from FIG.
the recording channel 5 containing, in cross-section v-shaped receiving piece 6 is provided with a saw blade 3 associated slot into which the saw blade 3 can dive to make a cut.
the saw blade 3 is also protected in the region of the working gap 9 in such a way that no engagement is possible from the side.
the receiving piece 6 is flanking with the above-mentioned slot, best seen in Figure 1 visible Abdeckschilden 19 which engage in the lower part 7 and upper part 8 forming, respectively U-shaped box.
the cover plates 19 are provided with recesses associated with the shaft 2 or the saw blade attachment.
the receiving piece 6 is provided with covers 20 which are laterally offset with respect to the recesses mentioned and which laterally flank the lower part 7 in the lowest engagement position, as can be seen from FIG.
the lower part 7 is provided in the region of the lower rear corner with an ejection opening 21 provided here in the lower region of the narrow rear wall, via which the airflow generated by the saw blade 3 can emerge and sawdust can be ejected.
the outlet opening 21 may open into the environment or into an associated disposal facility.
the ejection opening 21 is associated with a fixed to the lower part 7 connector 22 having a connection piece 23 for connecting a suction hose or a like a filter basket or the like. Trapped container. Of course, it would also be conceivable to connect such a collecting container directly to the lower part 7.
