  • a base body a swivel arm, a saw head, a saw blade
  • a blade guard holder a blade guard.
  • the guide rail is under, for example Intermediate layer of supports on a surface to be worked on. The roles interact positively with a corresponding profile of the guide rail.
  • the swivel arm is arranged laterally next to the base body and around an axis pivotable, which runs parallel to a plane in which the rollers lie.
  • a free end area the swivel arm is connected to the saw head on which the saw blade is attached.
  • the saw blade is in one plunge direction with the help of the swivel arm, d. H. from a starting position substantially perpendicular to that plane in the rollers are arranged, can be placed in a working position.
  • a blade guard holder is connected to the saw head, which is opposite to the plunge direction extends away from the saw head. This blade guard holder is used for recording and guiding the blade guard which at least partially covers the saw blade. Means positively interacting components of the base body, the swivel arm and The blade guard holder ensures that the blade guard holder is independent from the orientation of the swivel arm, always parallel to the immersion direction.
  • the blade guard which can be attached to the blade guard holder, is on one in the direction of immersion pointing free end open and has two recesses, which also are designed to be open in the immersion direction and are partially parallel to the Extend the total height of the blade guard measured in the direction of immersion. Both recesses have different, parallel to the immersion direction Length, the end region pointing in the immersion direction of that recess with the greater length forms a stop at which a counter to the direction of immersion pointing free end of the blade guard holder comes to rest when the saw blade or the swivel arm is in a starting position.
  • the saw blade When sawing, the saw blade is first moved from the starting position to the Working position moves. The saw blade dips into the ground. Subsequently there is a displacement of the entire sawing device in a perpendicular to Plunge direction of sawing along the guide rail by means of a Feed device. A cut is made from the saw blade in the ground.
  • the Distance between a free end region of the Blade protection and a blade protection stop pointing in the direction of immersion corresponds at most to the distance between one against the immersion direction facing surface of the blade guard holder and the one facing in the direction of immersion free end area of the blade guard.
  • the blade guard arrives essentially simultaneously with the beginning or shortly after Beginning of the immersion process of the saw blade in the subsurface, on the surface of the substrate to the system and the blade guard holder is moved against the blade guard in the immersion direction.
  • the view is through the leaf protection on the surface of the surface to the saw blade and thus to the processing point very badly affected. For the It is therefore very difficult for users to determine the immersion depth of the saw blade in the ground ascertain.
  • the immersion depth of the created slot can be, for example, by means of a Meterstick only after a corresponding displacement of the sawing device along the Guide rail.
  • the invention has for its object a safe and easy to use sawing device to create, with the immersion depth of the saw blade in the ground with simple means is displayed to the user.
  • the means for indicating the immersion depth of the saw blade are preferably from Marks formed, which are arranged on the blade guard holder and / or the blade guard are.
  • the markings are arranged, for example, on the blade guard Elevations, depressions or colored sections formed in the direction of immersion are arranged one behind the other.
  • the marking on the blade guard is expedient of at least a scale extending parallel to the immersion direction and the marking the blade guard holder formed from its counter surface.
  • the immersion depth is identical with the value on the scale that lies in the same plane as the counter surface the blade guard holder.
  • the scale is, for example, in several sections with 1cm Length divided and all sections are numbered, their value in the direction of immersion increases.
  • the Blade guard When the blade guard is attached to the blade guard holder, the Blade protection on the counter surface of the blade guard holder to the system. So the leaf guard in a direction parallel to the immersion direction compared to the The scale does not have to be aligned, advantageously the zero value of the Scale on the same level as the blade guard stop.
  • the diameter of the saw blade used in the sawing device depends the required immersion depth of the saw blade in the ground. To be a good one To be able to guarantee handling of the entire sawing device are for small Immersion depths Saw blades with a small diameter and for large immersion depths Saw blades with a large diameter are used. So that the user both when using a large saw blade, as well as with a small saw blade Immersion depth is always displayed, there are preferably two standards on the blade guard arranged, the zero value of a second scale in a first scale Immersion direction advanced by an amount that is half the difference in diameter of both Saw blades corresponds. For example, additional information on the two scales, which refers to the radius of the saw blade gives the user the Information on which scale to use for which saw blade diameter.
  • the counter surface of one is expedient formed against the immersion direction free end of the blade guard holder.
  • the sawing device shown in FIGS. 1 and 2 has a base body 1, a Swivel arm 2, a saw head 3, a saw blade 15, a blade guard holder 4 and one the blade guard 5 covering the saw blade 15.
  • the base body 1 has four rollers 17 provided, with the help of the base body 1 attached to a guide rail 12 and is displaceable along this.
  • the guide rail 12 is interposed by supports 13 fixed on the surface of a substrate 14 to be processed.
  • the basic body 1, not shown, contains one, not shown Drive motor which drives the saw head 3 on which the saw blade 15 is attached.
  • the saw head 3 is located on a free end region of the swivel arm 2, which is arranged laterally on the base body 1 and pivotable about an axis which is parallel to a plane in which the rollers are arranged.
  • At the Swiveling of the swivel arm 2 takes place on the saw head arranged saw blade in a direction substantially perpendicular to that Level runs in which the roles are arranged.
  • the saw head 3 is connected to a blade guard holder 4 which opposes one Immersion direction, i.e. in a direction facing away from the ground 14, from which Saw head 3 extends away.
  • This blade guard holder 4 has two spaced apart arranged and parallel to each other guides 16 on the recording and serve to guide the blade guard 5.
  • the swivel arm 2 and the Blade guard holder 4 ensures that the guides 16 of the blade guard holder 4, regardless of the orientation of the swivel arm 2, always perpendicular to extend in the plane in which the rollers 7 of the base body 1 are arranged.
  • the blade guard 5, which can be plugged onto the blade guard holder 4, is on one in the immersion direction pointing free end is open and has two recesses 10, 11th on, which are also open in the immersion direction and partially over the Extend the total height of the blade guard 5 parallel to the direction of immersion.
  • the length of the recess 10 extending parallel to the total height is greater than that Recess 11.
  • the recess 11 has a perpendicular to the direction of immersion measured width, which is larger than an intercept not shown between the swivel arm 2 and the saw blade holder 4.
  • the width of the recess 10 exceeds the width of the recess 11.
  • the sheet protection has mutually facing inner contours of the recess 10 Guide grooves 18 into which the guides 16 of the blade guard holder 4 are inserted can be.
  • the end regions of the guide grooves 18 pointing in the immersion direction form two stops 6 on a free against the direction of immersion End 7 of the blade guard holder 4 come to the system when the sawing device in a starting position.
  • the one on the scale 9 The value "500” corresponds to half the diameter of the saw blade with 1000 mm Diameter and the value "700” on the scale 8 corresponds to half Diameter of the saw blade with 1400 mm diameter.
  • the swivel arm 2 is pivoted in the immersion direction.
  • the saw blade 15 dips into the ground 14.
  • the distance L1 between one in the immersion direction free end area and one in the immersion direction Pointing stop 6 of the blade guard 5 corresponds at most to the distance L2 between a counter surface of the Blade guard holder 4 and the free end region pointing in the immersion direction Blade guard 5.
  • This arrives at the same time or shortly after the start of the immersion process of the saw blade 15 in the ground 14 of the blade guard 5 on the surface of the base 14 to the system and the blade guard holder 4 is moved opposite the blade guard 5 in the immersion direction.
