The following statement is a full description of this invention, including the best method of performing it known to me/us:

Rocker circular saw

The invention relates to a rocker circular saw according to the preamble of claim 1.

For example, generic rocker saws can be found in the two own intellectual property documents DE 20 2010 011 450 U1 and DE 10 2011 117 521 B3 as well as in European patent application EP 0 071 902 Al and German utility model G 83 27 078 U1. Such saws are used to cut firewood or the like and have a saw blade mounted rotatably and fixed in position on a frame with a lying axis horizontal, wherein the saw blade can be driven by an electric motor. A rocker with a workpiece carrier or a material receiving channel is hinged to the frame so that after inserting material to be cut, e.g. in the form of medium-thick branches, which then extends parallel to the axis of rotation of the saw blade, the material receiving channel together with the material to be cut can be swivelled in the direction of the saw blade and a safe cut through the material to be cut is achieved for the operator. Rocker circular saws of this type have already proven themselves many times in practice.

In the case of cross-cut saws, where instead of a bulk material channel accommodated on a rocker and a fixed saw blade, a rocker-operated saw blade is provided, it is already known to equip the saw with a collapsible and mobile saw table in order to be mobile with the saw in the working operation, see for example the US patent specification US 6,530,583 B1.

Also known are saws that have a saw table mounted on an extendable scissor frame to vary the cutting height. For example, Chinese patent application CN 107511530 Al shows a sawing device wherein the saw table is mounted on a frame designed as lazy tongs (Nuremberg scissors). Lazy tongs or Nuremberg scissors are sprocket chains consisting of several crossed scissor levers and are used, for example, in lifting platforms.

Based on the generic prior art, it is an object of the present invention to further develop a rocker circular saw in such a way that it is suitable for broader fields of application and user groups.

This object is solved by the features of claim 1.

A rocker circular saw according to the invention has a frame on which a saw blade is mounted stationary and rotatable about a preferably horizontal axis of rotation and on which a rotary drive for the saw blade is mounted. Furthermore, the rocker circular saw includes a rocker with a cut material receiving channel attached to the top of a cantilever. On a bearing arrangement, the extension arm is mounted pivotable about an axis parallel to the axis of rotation underneath or on the underside on the frame below the axis of rotation, so that the material receiving channel is pivotable towards and away from the saw blade between a sawing position and a material insertion position.

The rocker circular saw according to the invention is characterized in that the frame is designed as lazy tongs or Nuremberg scissors with joint axes extending in parallel to the axis of rotation, wherein the frame comprises a detachable locking device to lock the frame in an erected working position or to allow it to sink into a folded transport position. The bearing arrangement, with which the cantilever is attached to the frame, can be detached in order to place the rocker, which is hinged to the frame with its cantilever in the working position, on the frame sunken into the transport position after the bearing arrangement has been detached and the locking device has been released. The geometry and dimensions of the frame and the rocker are matched to each other in such a way that a cuboidal packing volume enclosing the rocker circular saw in the transport position is smaller than a cuboidal packing volume enclosing the rocker circular saw in the working position.

Due to the smaller packing size in the transport condition with the rocker laid on top, there are not only advantages in the storage of the rocker saw at the end user, but also in the storage in the sales department as well as in transport from the manufacturer to the individual trade levels.

Further advantageous further developments are subject of the subclaims.

In terms of the robustness required for the intended use of a rocker circular saw, combined with a lightweight construction, it is advantageous if the frame has two scissor legs connected to each other by cross bars, wherein each of the scissor legs is designed as a double scissor, i.e. each has two lower scissor levers and two upper scissor levers hinged on top of the lower scissor levers. In the working position, the cantilever can then be accommodated between the two scissor legs or can envelop the two scissor legs on the outside or be attached to one of the two scissor legs on the inside and to the other scissor leg on the outside, wherein the cantilever in turn advantageously has two cantilever bars connected by at least one cross bar and the cut material receiving channel, so that also in this respect a lightweight construction with high robustness results.

Therein, the locking device can comprise, at least on one, preferably on each of the scissor legs, a locking bolt, which in the working position connects and fixes the two lower scissor levers together and which is received with each of its two ends on a locking axle attached to the associated lower scissor lever and thus prevents the frame, which is erected in the working position, from folding.

Advantageously, the one end of the locking bolt on the one of the two advantageously lower scissor levers - an attachment of the locking lever to the two upper scissor levers of the respective scissor leg would also be conceivable - is designed in such a way that the locking bolt is fixedly but rotatably accommodated thereon, for example by the bolt axis being designed as a screw bolt and the locking bolt having a corresponding eye with which it is rotatably held fixedly on the screw bolt. The second axle assigned to the other end of the locking bolt can then be removably secured on the other scissor lever and, for example, be secured against removal with a safety split pin on the scissor lever there.

The frame can be locked not only in the upright working position but also in the sunken transport position if, in order to fix the locking bolt to the second removable - locking axle, a further receptacle for the locking axle in the transport position is provided in addition to a receptacle for the locking axle in the working position. Such a receptacle could be, for example, a lug on the respective scissor lever provided with a corresponding hole serving as an axle bearing. However, it would also be conceivable to design the two axle bearings as two holes next to each other penetrating the scissor lever.

Furthermore advantageous, a damper is provided which urges the rocker in the direction away from the saw blade. If the material receiving channel gets out of control of the operator, it is ensured that the saw does not come into contact with the material to be cut. For this purpose at least one damper rod may be attached to the rocker, for example to one of the cantilever bars, wherein the damper rod penetrates an eye provided for this purpose on the frame, which eye is preferably provided on one of the upper scissor levers, for example on a lug attached there. Around the damper rod penetrating the eye in the working position, a ring spring can be placed, which is supported with its one end on the lug containing the eye and to which on the side of the rocker a stop is assigned, for example at the rocker-side end of the damper rod, at which the ring spring engages when the rocker moves towards the saw blade. The damper rod can then be secured to the frame with a safety split pin behind the eye, so that the rocker can be easily detached from the frame at this point. The safety split pin can therefore be regarded as part of the detachable bearing arrangement for the rocker.

The bearing arrangement, by which the cantilever is pivotally mounted on the frame, advantageously connects two parallel, lower scissor levers to the cantilever with rotational freedom, whereby further two supports, for example on two parallel, upper scissor levers, are included in the bearing arrangement, for example, two inwardly projecting bolts with support rollers, e.g. made of rubber, on which the cantilever can rest in the cut material insertion position of the cut material receiving channel, so that the pivoting movement of the rocker away from the saw blade is limited to a degree corresponding to the cut material insertion position.

It is advantageous for sawing material in arm thickness or larger if the radius of the pivoting movement of the material intake channel is relatively large compared to the radius of the saw blade, whereby this is limited by the ergonomics of the rocker circular saw which need to be designed at table height. In addition, the material to be cut should strike the saw blade at an angle and in a position that helps to avoid unwanted kick-back forces induced by the saw blade on the material to be cut and thus on the rocker and on the operator. The axis of rotation of the saw blade, the potential point of impact of the cut material and the axis of the cut material channel should therefore be aligned with each other as far as possible.

In this sense, it is therefore advantageous if the bearing arrangement for hinging the cantilever to the frame has two rocker bearing bars projecting downwards from the two lower scissor levers, at which the cantilever is rotatably connected to the frame, wherein each of the rocker bearing bars carries at its lower end one of the bearing axles to which the associated cantilever bar is hinged. This enables the extension of the cantilever and thus the radius of the pivoting movement of the material receiving channel towards the saw blade, while at the same time the cantilever is positioned at a relatively slight angle to the vertical when the material to be cut hits the saw blade.

To connect the cantilever with the two lower scissor levers with a degree of rotational freedom in the angular range between the sawing position and the cut material insertion position, the bearing arrangement can comprise two rocker bearing axles, which can be designed as screw bolts, for example, and each of which projects inwards from one of the two parallel lower scissor levers or rocker bearing bars, to penetrate one of the cantilever's cantilever beams there. This way the cantilever can be removed from the frame just by loosening the screw connection and pulling off the rocker bearing axles, if necessary additionally by loosening the connection at the safety split pin of the damper rod. As an alternative to the screw bolts, simple socket pins secured with a safety split pin could be used as rocker bearings.

In order to create space for placing the cantilever on the frame sunken into the transport position, it is also advantageous if the saw blade is mounted on the frame on one side in the direction of the axis of rotation protruding the frame on the outside, so that there is space above the frame for the cantilever bars or the cantilever. The rotary drive or electric motor for driving the saw blade can also be arranged above the frame on the side of the saw blade facing the frame in the direction of the axis of rotation, as the rotary drive is relatively small compared to the extention of the saw blade in the radial direction, so that there is still enough space underneath the motor to place the cantilever or the cantilever bars.

The cantilever can be additionally fixed on the frame in the transport position by a motor suspension supporting the rotary drive and the saw blade having an insertion opening for inserting the cantilever bar of the cantilever facing the saw blade when the rocker is placed on the frame sunken into the transport position.

Around the saw blade, a saw blade cover can also be attached to the frame, which is interrupted on the side facing the cut material receiving channel, but otherwise at least largely closed. Material placed in the cut material receiving channel can then be fed to the saw blade by swivelling the rocker, whereby the saw blade is only in the relevant sawing area not covered by the saw blade cover. This reduces the risk of injury when operating the rocker circular saw.

If, in addition, a cover sheath is fitted there, which protrudes at the cut material receiving channel towards the saw blade and complements the saw blade cover to form a completely or almost completely closed saw blade housing, i.e. has two cover blades covering the area left free by the saw blade cover, an even further minimisation of the risk of injury is achieved. With regard to a small transport packaging size, it is particularly advantageous if the length of the cover sheath is matched to the height of the saw blade cover in such a way that the cover sheath does not protrude upwards over the saw blade cover when the rocker is placed on the frame sunken into the transport position.

Further advantageous, a pedestal element is attached to lower ends of the respective lower scissor levers located on a side of the frame facing away from the cut material receiving channel, wherein the pedestal element comprises a plurality of feet projecting downwards and a cross bar extending in the direction of the axis of rotation and connecting the lower ends.

In addition, a number of wheels can be mounted on the lower ends of the respective lower scissor levers on a side of the frame facing the material receiving channel.

In particular in the case of a saw blade projecting outwards beyond the frame on one side located in the direction of the axis of rotation and an adjoining rotary motor, it is advantageous in terms of a high resistance to tipping, if the frame has a pedestal element which projects outwards beyond the scissor frame on the side of the saw blade and has a pedestal on a side of the saw blade remote from the frame. This also applies to the wheels. Here, one of the wheels may be arranged at the side of the saw blade facing away from the frame, for which purpose, for example, the lower scissor lever supporting this wheel may be angled outwards.

Further features and advantages of the invention are explained in more detail on the basis of the embodiment of the invention shown in the figures.

Figure 1 shows a perspective side view of the rocker circular saw according to an embodiment of the invention in working position; figure 2 a further perspective side view of the rocker circular saw shown in fig.1 in working position; figure 3 a perspective side view of the rocker circular saw shown in figs.1 and 2 in transport position with rocker laid on top; figure 4 a further perspective side view of the rocker circular saw shown in figs.1 to 3 in transport position with rocker laid on top; and figure 5 a perspective side view of the frame of the rocker circular saw shown in figs.1 to 4 in sunken transport position.

Fig. 1 shows a rocker circular saw with a frame 1, to which a saw blade 2, which cannot be recognised under a saw blade cover 2a (in this respect reference is made to Figs. 3 to 5), and its rotary motor 3 are fixedly attached with horizontal axis of rotation. Furthermore, a rocker 4 is attached to the frame 1, with a cut material receiving channel 6 for the insertion of cut material and a cantilever 5, which is attached to the frame 1 in a rockable manner and supports the cut material receiving channel 6.

The frame 1 has a structure that can be erected and folded in the manner of lazy tongs or Nuremberg scissors, with two scissor legs 7, each of which has two lower scissor levers 8a, 8b and two upper scissor levers 9a, 9b as double scissors, wherein the scissor legs 7 are connected with each other by means of cross bars 11, 11a.

On the upper cross bar 11, an upwardly projecting motor support 12 is welded on, which carries the rotary motor 3 and the saw blade 2 connected to it. On the two lower scissor levers 8a, the lower ends of which point to the side facing away from the cut material receiving channel 6, a pedestal element 13 is screwed underneath, which has two feet connected by a cross bar. The cross bar extends in the direction parallel to the horizontal axis of rotation of the saw blade 2. On the other side, two wheels 13a are fitted to the two lower scissor levers 8b, whose lower ends point to the side of the cut receiving intake channel 6, to facilitate movement of the rocker circular saw.

The cantilever 5 has two cantilever bars 14, which are connected to each other via a cross bar 15 and the cut material receiving channel 6 and which are hinged to the frame 1.

The hinging points are located at the lower end of two rocker bearing bars 17 which project downwards from the two lower scissor levers 8a above a lower scissor joint and are shown in fig. 2. For the rockable attachment of the rocker 4 to the frame 1, a bearing arrangement designated 16, 17, 18 is provided, which on the one hand comprises the rocker bearing bars 17 and bearing axles 18 inserted at their lower ends, on which bearing axles 18 the two cantilever bars 14 are rotatably mounted and which bearing axles 18 are designed as removable screw bolts. On the other hand, the bearing arrangement 16,17,18 comprises two supports 16 inwardly projecting at the axes of the middle scissor joints between the lower scissor levers 8a and the upper scissor levers 9b, which are designed as rubber support rollers 16 pushed onto the inwardly projecting joint axes. The support rollers 16 thus limit the rocking movement in the direction away from the saw blade 2 to a position which is used for inserting material to be cut and in which the cut material receiving channel 6 is not penetrated by the saw blade 2.

To remove the rocker 4 it is enough to simply disengage the two cantilever bars 14 from the bearing axle 18 and release an additional connection of the rocker 4 to the frame 1 at a damper rod 27 which can in particular be easily seen in fig. 4.

The damper rod 27 is attached with its one end to one of the two cantilever bars14 and is inserted with its other end into an eye on a lug 29 of one of the two parallel upper longitudinal bars 9b of the frame 1 (as shown in fig. 5) and is secured there with a safety split pin 28 as shown in fig. 4. Around the damper rod 27 is a ring spring 26 which is also designated in fig. 2 and which is supported at one end on the lug 29 on the frame side and at its other end on a corresponding stop on the damper rod on the rocker side, thus urging the rocker away from the saw blade 2 during sawing.

After removing the rocker 4 from the frame 1, the frame 1 can be folded from its upright working position shown in figs. 1 and 2 into its transport position shown in figs. 3 to 5.

For this purpose, a locking device 10,19,20,21 must be released, which holds the frame in the erected working position. The locking device 10,19,20,21 comprises a locking bolt 10, as shown in particular in fig. 2, which is received with each of its two ends on a locking axle 19,20 attached to the associated lower scissor lever 8a,8b. In the position of the locking bolt 10 attached to the two lower scissor levers 8a,8b, this prevents the frame 1 from collapsing.

One of the two locking axles 19,20, namely the locking axle 19 attached to the lower scissor lever 8a, is inserted as a removable bolt into a bearing eye formed on a lug on the lower scissor lever 8a and secured against being pulled out with a safety split pin 21. If - after removing the rocker 4 - the safety splint 21 is now pulled off and the bearing axle 19 removed, the frame 1 sinks into its transport position, see fig. 5.

To transport or pack the rocker saw in transport or packing condition, which is angular and relatively compact as compared to its working position and which requires only a small packing volume or a small storage area, the removed rocker 4 is laid, as shown in fig. 3 and 4, on the frame 1, which has been lowered into its transport position as shown in fig. 5.

In order to create space underneath the rotary drive 3 for the cantilever bar 14 to be placed there, the motor suspension 12 has a slide-in channel or slide-in opening 30 (see fig. 5) through which the corresponding cantilever bar 14 can be inserted.

Deviations and modifications from the shown embodiment are possible without leaving the scope of the invention.
