Wall or floor saw

A wall or floor chain sawing device comprising:

• a chain bar assembly comprising:
• a chain bar guiding a chain at least partly around a perimeter of the chain bar, the chain bar having a longitudinal extension,
• a chain bar housing attached to and partially covering the chain bar and the chain;
• and
• a supporting plate to which the chain bar and the chain bar housing are attached;
• a motor;
• a track interface arranged to co-operate with a guiding track;
• a power transmission arrangement adapted to transfer a motion from the motor to the chain;
• and
• a first pivotable support rod and a second pivotable support rod,
• wherein each of the first pivotable support rod and the second pivotable support rod has a corresponding first end and second end,
• wherein each first end is pivotably attached to a first mounting bracket, the first mounting bracket being at least indirectly attached to the motor,
• wherein each second end is pivotably attached to a second mounting bracket that is comprised in the chain bar assembly,
• wherein the first pivotable support rod and the second pivotable support rod are configured to move the chain bar assembly in a circular movement in a cutting plane while maintaining the chain bar assembly in a direction of the longitudinal extension of the chain bar within the cutting plane, and
• wherein the second mounting bracket is releasably mounted to the supporting plate by a releasable attachment means that runs in an adjustment slot in the second mounting bracket, wherein, when released, at least a part of the releasable attachment means is adapted to travel within the adjustment slot, allowing the longitudinal extension of the chain bar to be adjusted to a desired angle.

• a motor;
• a track interface arranged to co-operate with a guiding track;
• a power transmission arrangement adapted to transfer a motion from said motor to the chain;
• a locking arrangement configured to move between a first locking position and a second locking position;
• and
• a first pivotable support rod and a second pivotable support rod,
• wherein each of the first pivotable support rod and the second pivotable support rod has a corresponding first end and second end,
• wherein each first end is pivotably attached to a mounting bracket, the mounting bracket being mounted to a holding frame via the locking arrangement arranged in the second locking position, the holding frame being mounted to the motor,
• wherein each second end is at least indirectly pivotably attached to the chain bar assembly,
• wherein the first pivotable support rod and the second pivotable support rod are configured to move the chain bar assembly in a circular movement in a cutting plane while maintaining the chain bar assembly in a direction of the longitudinal extension of the chain bar within the cutting plane,
• wherein a support rod plane runs through the first pivotable support rod and the second pivotable support rod and a locking plane runs through the locking arrangement,
• wherein, in the second locking position, the locking arrangement is positioned between the first pivotable support rod and the second pivotable support rod such that the support rod plane and the locking plane are separate from each other, and
• wherein, in the first locking position, the locking arrangement is positioned between the first pivotable support rod and the second pivotable support rod such that the support rod plane and the locking plane coincide.

• a motor;
• a track interface arranged to co-operate with a guiding track;
• a power transmission arrangement adapted to transfer a motion from said motor to the chain, the power transmission including a first end pivotably connected to an output shaft of the motor and a second end pivotably connected to an input shaft of the chain bar housing;
• and
• a first pivotable support rod and a second pivotable support rod,
• wherein each of the first pivotable support rod and the second pivotable support rod has a corresponding first end and second end,
• wherein each first end of the first pivotable support rod and the second pivotable support rod is pivotably attached to the motor via a first mounting bracket,
• wherein each second end of the first pivotable support rod and the second pivotable support rod is pivotably attached to a second mounting bracket that is comprised in the chain bar assembly,
• wherein the first end of the power transmission arrangement is configured to rotate about a rotation axis of the output shaft of the motor,
• wherein the second end of the power transmission arrangement is configured to move in an arc in a same or parallel plane with a pivotable movement of the first pivotable support rod and the second pivotable support rod,
• wherein the chain bar assembly comprises a supporting plate to which the chain bar and the chain bar housing are attached,
• wherein the second mounting bracket is releasably mounted to the supporting plate by a releasable attachment means that runs in an adjustment slot in the second mounting bracket, and
• wherein, when released, at least a part of the attachment means is adapted to travel within the adjustment slot, allowing the longitudinal extension of the chain bar to be adjusted to a desired angle.
